Title: Circuit arrangement for signal level adaptation in electronic digital technology
Inventor: ERBELE KURT
IPC: H03K19/018
Filed: 1985-06-13
Abstract: The invention concerns a circuit arrangement for signal level adaptation in electronic digital technology, between a signal output (SA) of a first switching circuit system (S1) and a signal input (SE) of a second switching circuit system (S2), the first switching circuit system (S1) being supplied from a first operating voltage source (B1), and the second switching circuit system (S2) being supplied from a second operating voltage source (B2), one of the two poles of each operating voltage source (B1, B2) being in each case connected to a reference potential (BP) in such a way that the poles which are not connected to the reference potential (BP) have different polarity relative to the reference potential (BP). The circuit arrangement has two transistors (TS1, TS2), which are complementary to each other. The reference voltage element (D1) causes safe transition of the first transistor (TS1) from conducting to blocking state and vice versa, on changing from the first limit signal level value (SP1max) to the second limit signal level value (SP2min). The first resistor (R1) limits the collector current of the first transistor (TS1) (Fig. 1). <IMAGE>

Title: Transfer device for forming machines and the like
Inventor: WISEBAKER ROBERT E
IPC: B21D43/05
Filed: 1985-06-29
Abstract: A transfer device for forging machines has grippers which open wide and are mounted on a transfer slide which can be moved backwards and forwards between a pick-up position and a release position. Two gripper fingers are articulated at one end on a piston of a pneumatic spring carried by the transfer slide and between their ends, are connected rotatably to connecting members which, for their part, are articulated on the transfer slide. In the gripping position of the system, the connecting members are inclined in such a way that gripping portions of the grippers are moved together in order to grip the workpiece. When the grippers are open, the connecting members move to an alignment position, the grippers being spread apart in order to release the workpiece, and the fingers being caused to move sideways, freeing the workstation and allowing a return movement of the transfer device to the pick-up position to be initiated before the tooling frees the workstation. The geometry is such that wide opening operations are provided, allowing the grippers to free shoulders on the workpieces and to free the tooling which forms the workpieces in the dies of the machine.

Title: Method for producing highly compressed heating bodies using PTC thermistor heating elements
Inventor: HILLINGER ERICH
IPC: H05B3/52
Filed: 1985-12-03
Abstract: During the production of highly compressed heating bodies which are provided with PTC thermistor elements or PTC elements, it has been found that, if the compression is carried out in a normal manner (that is to say by pressing, rolling or hammering) the heating elements (which are intrinsically very brittle and thus can be loaded only in compression) break up and thus can become unserviceable. The object was thus raised of finding a compression method which, in conjunction with a suitable construction of the heating body loads its heating elements essentially only by compression forces, that is to say largely precludes bending and tensile stress within the heating body. This object is achieved according to the invention in that the heating bodies, whose heating elements are arranged between rail-like power supply lines, are closed in a sealed manner by a cap consisting of elastic material, are then inserted into a high-pressure container which is filled with a fluid medium and, via this medium are subjected to a high pressure which acts on the heating bodies on all sides and produces a reduction in the volume of the heating bodies.

Patent DE-3601035-A1 (DE)
Title: Bubbling device with perforated plate elements for atomisation of gaseous media in the bath water
Inventor: FRENKEL WALTER
IPC: A61H33/02
Filed: 1986-01-16
Abstract: In order to facilitate exchange of a plate element 1 of a bubbling bath installation which forms fine bubbles, the element has on its underside an annular connecting web 1c which engages in a recess 3a in a circular grid 3 in sealing and releasable fashion; the circular grid 3 is firmly fitted concentrically around a perforation 2c, preferably at the underside of a top film 2a of the bubbling bath installation. Within the connecting web 1c the perforation portion 1a of the plate element 1 is preferably depressed like a well. This depression and the fact that the circular grid 3 is located inside the bubbling bath installation require a low height of the components, which is desirable from a safety point of view, and ensure that the formation of fine bubbles is scarcely impaired by the body of the individual taking a bath. If the plate element is obstructed, for example by lime or bath additives, it can be removed, cleaned or exchanged for a new one in a very simple manner. The bubbling bath installation can be re-used in this way. The sealing connection between the connecting web 1c and the recess 3a is effected via a snap-on connection, a bayonet catch, a cone connection or a screw thread. <IMAGE>

Title: Universal joint
IPC: F16D3/41
Filed: 1986-02-22
Abstract: The proposal is for a universal joint which consists of a spider and of respective yokes, the two fork arms of which, each of which contains a bearing hole, are pivotably mounted, by means of a bearing bush and bearing elements, on an end pin of the spider. The outer circumferential surface of the bearing bush is cylindrical. The shape of the inner circumferential surface, as seen in cross-section, is non-circular, the inner radius varying in the circumferential direction, when measured from the centre line of the bearing bush, in such a way that this dimension is larger in the circumferential area of loading by higher forces than in the circumferential area of loading by smaller forces. The inner radius is enlarged where the largest bearing forces act. While retaining simple production and assembly, for the same price, of the universal joint, which remains small, light and compact, a considerable increase in the life of the bearings - by a factor of 2 or more - is thereby achieved.
