Patent DE-3465942-D1 (DE)
Title: Locking tail-gate assembly
Inventor: OLINS RICHARD C
IPC: E05C19/06
Filed: 1984-03-13
Granted: 1987-10-15
Abstract: A tail-gate assembly comprises a stationary support, a slide mounted on the stationary support, a platform pivotally mounted on the slide, a latch member mounted on and projecting laterally from said loading platform, a latch plate mounted on said stationary support. The latch plate has a latch notch formed therein which has an entrance way opening in a direction to admit the latching member. The notch is proportioned to receive said latch member in a close fitting relationship so as to provide a vertical restraint limiting vertical movement and a rotational restraint limiting rotational movement of said platform. A pair of latching jaws each having a locking tooth at one end thereof, are mounted on the latch plate for pivotal movement between a closed position in which the locking teeth extend inwardly from opposite sides of said entrance way to prevent withdrawal of the latching member from said notch and an open position in which the teeth are displaced outwardly from said entrance way to admit and release the latching member. A closure spring normally urges the jaws toward the closed position, the closure spring is adapted to yield to permit the jaws to open in response to contact with the latch member as it is moved into engagement therewith. An actuator is provided on the jaws which is adapted to cause the jaws to interact with one another whereby movement of one jaw toward the open position causes movement of the other jaw toward the open position.

Abstract: PCT No. PCT/FR86/00028 Sec. 371 Date Oct. 3, 1986 Sec. 102(e) Date Oct. 3, 1986 PCT Filed Feb. 3, 1986 PCT Pub. No. WO86/04533 PCT Pub. Date Aug. 14, 1986.Improvements to machines for heating articles or products by condensation of primary vapor on said products or articles, the primary vapor isolated from the atmosphere by a secondary vapor mass. According to the invention, a first improvement is aimed at lowering the chlorine and fluorine ion contents in the primary and secondary vapors of the plant resulting from the decomposition of said vapors. To this effect, the invention provides an improved washing of the secondary liquid. Furthermore, a dry gas sweeping between damp atmospheric air and the secondary vapor prevents the introduction of atmospheric moisture. Another improvement relates to the automatic compensation of variations in operating conditions by controlling the power balance.

Abstract: Regeneration of a spent hydrocarbon conversion catalyst is accomplished by means of a moving bed of catalyst, where catalyst is passed through several treatment zones, in a unique regeneration vessel. The catalyst is first contacted with a hot oxygen-containing gas stream in a burning zone in order to remove coke. The catalyst is then passed into a drying zone for removal of water formed in the combustion zone by passing a hot dry air stream through the catalyst. This hot air stream is produced by exchange of heat with catalyst, thereby effecting cooling of the regenerated catalyst and by use of an air heating means located in the vessel. After passing through the drying zone, the air stream provides oxygen for combustion in the combustion zone.

Abstract: A bellows integral with a collection reservoir includes a handle grip reciprocable alternately to draw vomit into the reservoir from an attached catheter insertable into the throat, and vent air through an exhaust valve.  The  bellows-reservoir unit is detachably mounted to a frame which also includes a handle grip and springs. The grips are squeezed to draw in vomit and released to permit the springs to collapse the bellows.  The operation is one-handed, the device is portable, and the bellows-reservoir unit can be separated from the frame and discarded after use.  A one-way inlet valve in the catheter prevents vomit from draining back into the throat during aspirator operation.

Abstract: The excavator of the present invention has wheels which are suspended or respectively attached in a special way. When the excavator moves or is transported, the wheels are in their vertical normal position and for excavating purposes preferably all wheels are tilted sideways. This measure increases the seating surface of the excavator and therefore its stability on the ground. For this purpose, the wheels are tiltingly attached to axle extensions which can be moved in the direction of the axle. The said axle extensions are pulled in when the excavator moves, and for excavating tasks are pushed out towards the side whereby the tilting of the wheels takes place. Pistons inside the axle effect the moving of the axle extensions.
