IPC: B01J31/16
Filed: 1976-08-09
Granted: 1982-07-16
Abstract: A process is described for preparing aromatic isocyanates by contacting an aromatic carbamate of the formula R(NHCO2R')n at 150 DEG -350 DEG  C under reduced pressure with one or more metal or metal compound catalysts dissolved in an inert solvent. In the formula R is a divalent aromatic, R' is a monovalent aliphatic, alicyclic or aromatic with at most 8 carbon atoms and n is 1 or 2. The metal is dissolved in a concentration of at least 1/1000% by weight of the solvent. The vapors of the resulting aromatic isocyanate and alcohol or phenol are fractionally condensed under reduced pressure and the aromatic isocyanate is separately collected.

Abstract: A pressure operated electrical switch and an alarm system for use in hospitals and nursing homes is constructed such that a force is applied to a pressure plate therein. Once the load is reduced below a predetermined value the pressure plate will move under spring influence to close/open a microswitch or electrical contact means. The normal force applied to the pressure plate is the load on the leg of the hospital bed when occupied. If the bed occupant gets out of the bed the load on the pressure plate is reduced below a predetermined value, and the consequent movement of the pressure plate opens/closes the switch means to actuate the alarm.

Abstract: A device for automatically closing the elevator deck of lift gate is actuated by a drive device and constituted by a parallelogram deformable under the action of the drive device. The arm of the parallelogram intended to support the elevator deck extends beyond its point of articulation on the lower adjacent arm of the parallelogram, thus defining an extension. The elevator deck is articulated on the lower end of the extension of the arm supporting the elevator desk. An articulation element of adjustable variable length is mounted to pivot, on the one hand, on the elevator deck and, on the other hand, at an appropriate point of the chassis or of the upper arm of the deformable parallelogram, so that the distance between these two points of articulation of the element of articulation of variable length decreases when the lift gate is being raised. When the element of articulation takes its position of minimum length, it acts as a fixed connecting rod causing the elevator deck to pivot at the end of lift of the lift gate from a position determined by the prior adjustment in length of the element of articulation to a new position.
