Title: Cam-roller catch for maintaining car door open - has plastics roller on elastic mounting which yields and recoils as cam is traversed
IPC: E05C17/52
Filed: 1977-01-21
Abstract: The cam-roller catch for car doors holds the door open and now inc. an elastic roller-mounting improving the durability of the mechanism. The roller (111) traverses the peak of a bi-ramped (A, B) cam as the door (119) opens, and the mounting successively yields and recoils as the peak is traversed. The return of the roller over the peak of the cam is, thus resisted, by the elasticity of the mounting. The roller is of durable plastics with a low coefficient of friction, and is mounted on an axle (112) spanning the legs of a 'U' piece (113). The 'U' shape piece is in turn mounted on the free end of a cantilever blade-spring (35) which is bolted (36) to the door. A cellular elastic buffer (39) may interpose the free end of the blade-spring and the wall of the door post.

Patent ES-484655-A1 (ES)
Title: Process for the continuous dehydration and calcination of hydrated aluminum fluoride for the manufacture of high purity aluminum fluoride
IPC: C01F7/50
Filed: 1979-10-02
Abstract: The invention relates to a continuous, two-stage process for complete dehydration and subsequent calcination of aluminum fluoride hydrates. The known processes used for this purpose are satisfactory for producing relatively small quantities of aluminum fluoride. In the production of larger quantities of aluminum fluoride however several problems arise with respect to trouble free control and supervision of the process and maintainance of the equipment. The disadvantages which up to now have been mainly due to the process itself are removed by the combination of the following process steps: (a) Dehydrating the aluminum fluoride hydrate in a first step, to produce aluminum semi-hydrate AlF3.0.5H2O by means of a generally known method (b) heating the aluminum semi-hydrate in a second stage in an indirectly heated, horizontal rotary kiln to remove the remaining water of crystallization, and then calcining at ca. 500 DEG -600 DEG C.

Title: Self organising general pattern class separator and identifier.
IPC: G06T7/00
Filed: 1981-03-25
Abstract: A system is provided for the separation into and the indentification of classes of events wherein each of the events is represented by a signal vector comprising the signals s, sz . . . , sj . . . , sN. The system comprises a plurality of assemblies, each of the assemblies including a matrix of junction elements for respectively receiving as inputs the different respective signals of a vector. The junction elements provide a transfer of information Aijs, i.e., the product of the transfer function of the element and the signal input applied thereto. The information transferred by the junction elements is summed in each assembly. In the training mode of operation information summed in each assembly is applied to a scalar multiplier and the resulting information is in turn applied to a threshold stage which is actuated to produce an output if the input applied thereto attains a prescribed value. Concurrently, the summed outputs of the junction elements are fed back to these elements to modify their transfer functions. The outputs of the threshold stages are finally processed for identification of the classes of events.
