Development and characteristics of high pressure control valv

Remotely operated high pressure valve protects test personnel

High pressure valve used in testing certain spacecraft systems is safely opened and closed by a remotely stationed operator. The valve is self-regulating in that if the incoming pressure drops below a desired value the valve will automatically close, warning the operator that the testing pressure has dropped to an undesired level

Insertion device for pressure testing

Test device which introduces either pressure or vacuum into a test pipe or tube, is insertable into the tested item where it secures itself into position and requires no external support. The unit has an operating range from zero to 25,000 psig and to any vacuum level that available equipment can reach

Replaceable filters and cones for flared-tubing connectors

Connector is modified by machining the cone from one end before the fitting is bored to accommodate a metallic-filament type of slip-in filter. Thus, when surface of the cone is damaged, only the cone needs replacement

An analysis of local solicitors’ attitudes to and use of mediation

Legal practitioners are considered to be the “gate-keepers” for a significant proportion of the mediation work currently being undertaken in the UK. This small-scale study undertaken in Canterbury explores the attitudes of local legal practitioners to mediation and as its use as a process for resolving disputes. The study provides an initial review of current research in the field of civil mediation in the UK, which whilst limited and now a little dated, reveals some practitioner ambivalence towards mediation and potentially provides some key themes regarding legal practitioners’ uncertainty about the use of mediation. This could arguably go some way to explain why mediation is not more widely used for a range of dispute categories. The data collected from local legal service providers who practice in the areas of family law, civil and commercial law and employment law, reveal some key themes. The then study draws a range of conclusions, both positive and negative regarding the use of mediation in the area of family law practice and the attitudes of law firms are highlighted and contrasted with those of individual solicitors. The responses from the participants associated with civil and commercial practice areas tended to be more positive, particularly with regard to the idea of introducing a more compulsory element to the use of mediation, whilst the responses from those practitioners in the area of employment law seemed to suggest a lack of use and understating of the process. The study concludes with the view that the findings from local practitioners appear to reinforce the research undertaken by Professor Dame Hazel Genn in a study she undertook some seven years ago, and do indicate that the attitudes of legal service providers towards mediation are still mixed. This may serve to explain (at least in part) why mediation remains significantly under-used and the changes introduced by the government to encourage the use of mediation have so far not been received that favourably by all legal practitioners

Solicitors attitudes to mediation - a Canterbury study

The area of dispute resolution and particularly ADR provides a research rich landscape. It is therefore somewhat surprising that little empirical research has actually been undertaken in this area in the UK. Such university-based research not only encourages outreach into the legal services community and assists knowledge exchange activities, but also informs and enriches the undergraduate Law curriculum and on a macro level, can achieve impact and recognition through influencing policy-making. A recent small-scale study undertaken by the Canterbury Christ Church Mediation Clinic which is part of the School of Law (The Christ Church Study) into solicitors’ attitudes to mediation has been undertaken and the findings are compared to those of an earlier study undertaken by Dame Professor Hazel Genn

Perceptions of Regular Education and Special Education Professionals Regarding Involvement in the IEP Process

Special education and regular education professionals in public high schools in Virginia were surveyed regarding their perceptions of student, parent, special and regular educator involvement in the IEP conference. The survey aimed to compare the teachers\u27 perceptions on the ideal level of involvement with what actually occurs in the schools. Students and regular education teachers had lower levels of actual involvement in the IEP conference than the teachers believed it should be. Furthermore, both groups of teachers indicated that the primary responsibility for developing the IEP should fall to the special education professional

Bench vise adapter grips tubing securely and safely

Plastic self-compressing adapter with grooves, attached to the jaws of a bench vise, secures thin-wall tubing vertically or horizontally during cutting and flaring operations without marring or damaging it. Magnets incorporated in both sections of the adapter prevent detachment from the jaws when the vise is opened

Perturbation of an Eigen-Value from a Dense Point Spectrum : An Example

We study a perturbed Floquet Hamiltonian $K+\beta V$ depending on a coupling constant $\beta$. The spectrum $\sigma(K)$ is assumed to be pure point and dense. We pick up an eigen-value, namely $0\in\sigma(K)$, and show the existence of a function $\lambda(\beta)$ defined on $I\subset\R$ such that $\lambda(\beta) \in \sigma(K+\beta V)$ for all $\beta\in I$, 0 is a point of density for the set $I$, and the Rayleigh-Schr\"odinger perturbation series represents an asymptotic series for the function $\lambda(\beta)$. All ideas are developed and demonstrated when treating an explicit example but some of them are expected to have an essentially wider range of application.Comment: Latex, 24 pages, 51
