Title: Electric line connecting clamp - has insulating housing with cylindrical depression and resilient protrusion, reducing aperture at end furthest from inserting point
IPC: H01R4/30
Filed: 1980-03-21
Abstract: The clamp can be used as a terminal box and has an insert with a screw for line securing. The insert with the screw is arranged in an insulating housing with a cylindrical depression for the screw guiding and for preventing dropping out. The cylindrical depression (15) has a protrusion (24) on the end, away from the insert (12), which is of flexible material and reduces the depression opening. Thus the opening is smaller in the region of the protrusion than the diameter of the screw head, but greater than that of the screw stem. The length of the screw (20) with its head is greater than the length of the depression from the clamping insert to the protrusion. Preferably the screw end is tapered and/or the threaded bore (19) in the insert has an increasing diameter towards the screw. Both the screw tip and the threaded bore may be conical.
Patent DE-3013716-A1 (DE)
Title: Transmitter circuit for radio controlled model - operates on two servo motors simultaneously controlling differing functions
IPC: A63H30/04
Filed: 1980-04-12
Abstract: The controller enables the transmission simultaneously of two signals to separate servo motors to permit the desired symmetry. The single controller (10) feeds a voltage follower (12) acting as a buffer amplifier. The amplifier output divides into two channels which pass to the input terminals of an electronic switch (16). One channel passes directly to the switch, the other via an attenuator (14). The output of a detector (15) connected to the direct channel controls the position of the electronic switch. Depending upon the position of the controller (10), and hence on the output polarity of the voltage follower (12), the attenuated channel is connected to one or other of the switch outputs (17,18) and the unattenuated channel to the opposite output (18,17). The switch outputs go to the transmitter. The effect of one channel with respect to the other can readily be adjusted by trimming the attenuator (14) to take account of the handling characteristics of the aeroplane. A typical application of the controller is to setting aileron position in a model aeroplane. When turning and banking the deflection of the ailerons may with advantage not necessarily be the same on each wing.

Patent DE-3023765-A1 (DE)
Inventor: MUELLER WOLFGANG HANS EDUARD D
IPC: C07C67/38
Filed: 1980-06-25
Abstract: A process for preparing fatty acid esters by reacting olefins, aklanols and carbon monoxide in the presence of a compound of cobalt and a promoter consisting of pyridine, non-orthosubstituted alkylpyridines or mixtures thereof. The reaction output is at first treated with a gas containing oxygen in a non-damaging manner and then reprocessed in two distillation stages. The first distillation stage is operated at a higher pressure than the second. In the first distillation stage there is produced a distillate free of cobalt and a sump product containing all of the cobalt used as catalyst. In the second distillation stage the sump product of the first distillation stage is again distilled to produce another distillate free of cobalt and a cobalt concentrate as sump product. This cobalt concentrate is incorporated into pyridine, a non-orthosubstituted alkylpyridine or a mixture thereof to form a suspension. The suspension is then treated by a mixture of carbon monoxide and hydrogen at a temperature of 100 DEG  to 250 DEG  C. and a pressure at least 50 bars, and this treatment product is fed back into the fatty acid ester synthesis.

IPC: B65B27/00
Filed: 1980-06-27
Abstract: Steel wire, for example annealed welding wire, is welded together to form a ring having a circumference approximately 4.5 times the height of the netting stack (1) or the diameter of the bundle. The ring is stretched out to form a loop (6) which is caught by means of lozenges in the netting stack (1) in the vicinity of the corners of the latter or is drawn under the bar bundle, bent up around this and tied round it. By means of a mandrel (7) inserted into the projecting lugs (8), these are rotated to a minimum of 180 DEG , so that the loops, into which crane hooks can be introduced, are obtained. It is therefore no longer possible for twisted steel wires to slide apart from one another, as hitherto. <IMAGE>

Title: Method for automatic, transaction-time dependent generation of cryptographic codes for encryption and decryption of information
Inventor: EICHEL DIETRICH
IPC: H04L9/08
Filed: 1981-10-07
Abstract: In data processing system memory areas protected by passwords and technical system measures or in transceiver units of office computer or microelectronic systems designed according to esoteric principles, in which access to protected memory areas is secured by means of a personal identification number, on the basis of the date and time of a transaction time synchronised between the source (transmitter) and the sink (receiver) or the difference between a synchronised time and the transaction time with a secret, irreversible algorithm, either an address is calculated in a protected memory area and at this location in the transceiver unit a code number of defined length is used for the encryption or decryption of information, where identical (two-way) or complementary (one-way) codes may be involved in the transceiver unit or a two-way code is calculated directly. The method is suitable for a large number of applications in which information is transmitted from a source (transmitter) to a sink (receiver) and needs to be authenticated for security reasons and/or needs to be encoded in the transmitter for data protection or other secrecy reasons and converted back into open information in the receiver, where the transaction time can be incorruptibly restricted within the system to a specific time and/or can be correspondingly documented.

Patent DE-3146818-A1 (DE)
Title: Mechanical actuating device for disc brakes
Inventor: FELDMANN JOACHIM ING GRAD
IPC: F16D55/14
Filed: 1981-11-26
Abstract: Disc brakes have the disadvantage compared to drum brakes that the braking force fed in by the actuation of the brake is not reinforced. In disc brakes, the self-reinforcing factor in the application of the brake linings must be achieved by a higher power. The application elements are pressed against the brake discs in an axial application movement via oblique tracks. According to the invention, these oblique tracks are divided into a large and a small angle of inclination, the large angle of inclination being assigned to the free path of the application elements up to the point of contact of the brake linings with the brake discs and the small angle of inclination being assigned to the region which applies the application force.
