PURPOSE:To improve safety by disabling a vehicle from starting at the time of pressure failure by controlling a shift lock device to inhibit its lock release, when a pressure in a pressure source not more than a present pressure is detected by a pressure detecting switch. CONSTITUTION:When a brake pedal 7 is stepped in, pedal step-in force is boosted with a booster 3 by pressure fluid from an accu...

PURPOSE:To prevent deterioration of shift feeling by controlling an output adjusting means so that the input rotational frequency decreases according to a designated change characteristic when a select operation from a non- running range to a running range is detected by a select operation detecting means. CONSTITUTION:When a select operation from a non-running range to a running range is detected...

Hydrogenation catalysts, which have a specific surface area of from 50 to 150 square meters per gram, solely or partially contain crystals having a spinel structure and copper in the form of copper oxide, and have been obtained by precipitating copper and aluminum in a ratio of from 0.25 to 3 atoms of copper per atom of aluminum from their compounds in the presence of a carbonate at a pH of from 4...

Tapered roller bearing cage has an inner (11) and outer (12) ring connected by ribs (13). There are pockets (16) on the underside of the ribs (13) as well as openings (18) on the lower circumferential surface (9) of the inner ring (11) between adjacent ribs (13). The inner ring (11) can have additional pockets (20) with slanted sides on the upper circumferential surface (8). The cage can be made o...

L'invention permet de déterminer la couleur à donner en particulier à une prothèse dentaire à partir de la mesure de la couleur des dents adjacentes dans la bouche du patient. Un instrument à fibre optique permet de capter la lumière réfléchie par une dent et de la transmettre à l'entrée d'un spectrocolorimètre associé à un microprocesseur, pour déterminer la réflectance spectrale diffuse de la de...

The method and apparatus of the invention use a beam of laser emitted optical energy to effect wound closure and reconstruction of biological tissue. In response to input as to tissue type and thickness, a computer determines the output power, exposure time and spot diameter of the emitted beam to control the application of optical energy to produce thermal heating of biological tissue to a degree...

The frame for a collapsible canopy is suspended on an externally threaded shaft which extends downwardly from a head in a concave socket at the free end of an overhead supporting arm. A nut which mates with the shaft beneath the frame can be rotated by way of a downwardly extending handle to move the frame into frictional engagement with the underside of the socket while urging the head against th...

A releasable, swivelable, quick connector assembly comprises a tubular male member, a tubular female member having an end portion configured to mate with the male member when inserted therewithin, and a retainer member including means for preselectively resisting assembly of said male member into said female member where said retainer is preassembled onto male member and where said retainer is pre...

A monoclonal antibody which binds preferentially to a subset of the human CD8 lymphocyte population whereby to positively and precisely distinguish between cytotoxic effector and supressor effector cells in the CD8 cell population. The monoclonal antibody recognizes a novel epitope of LFA-1 antigen by means of which it can bind CD8 cells which express the eptope on a surface antigen thereof. The C...

Disclosed are blends of about 99 to about 10 weight % of poly(ethylene terephthalate) and about 1 to about 90 weight % of a polyester of trans-4,4 min -stilbenedicarboxylic acid and at least one aliphatic glycol having 2 to 16 carbon atoms. The blends have improved gas barrier properties and improved chemical resistance.

An integrated alarm and access control system includes an access control package, an intrusion detection package and an interface unit. A position sensor determines if a door is open or closed and an electrically activated locking device locks the door in its closed position. A supervisory circuit provides line security. A door position relay and a first timer prevent an alarm signal from the supe...

A means and method for applying innerliner material to a tire building drum and more particularly to a means and method for cutting and applying the innerliner material and further allowing for stock width measurement and precise centering without the possible edge distortion of known guiding systems.

Process for the preparation of flexible polyesterpolyurethane foams by reacting at least bifunctional polyesterols with at least bifunctional organic isocyanates in the presence of catalysts and of a stabiliser mixture of organic and organosilicon compounds, water, optionally blowing agents and optionally conventional additives, in which a stabiliser mixture is used which consists of   a) a (me...
