Title: Serial tetrad adder/subtractor in BCD-8421 code with negation complement circuit
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1984-07-06
Abstract: This tetrad adder/subtractor has as the main circuit a dual tetrad adder 1 and as a correction circuit a subtracting circuit 2 for subtracting the number 6 and has a pre-adding circuit 3 for the addition of the number 6 by means of which the number 6 is added to the summand present at the B inputs during the addition and which does not have a nines complement circuit but a fifteens complement circuit for executing additive subtractions because the normal negating complement circuit is a fifteens complement circuit in BCD-8421 coding. The additions are thus carried out normally in this adder/subtractor and the subtractions are carried out by means of additive subtraction. During the subtraction, the B inputs are the minuend inputs and the A inputs are the subtrahend inputs. During the addition, the complement environment is preactivated in the circuit 4 and the pre-adding circuit 3 is preactivated. During the additive subtraction, the complementing is preactivated in the circuit 4 and the pre-adding circuit 3 is not preactivated. <IMAGE>

Title: Furniture
Inventor: SCHLEY PETER
IPC: A47B47/03
Filed: 1984-08-18
Abstract: This is an office cabinet whose sides are constructed as gap-forming double walls consisting in each case of an inner side piece and an outer side piece, it being possible for the outer side piece to be connected directly to the inner side piece, that is to say dispensing with the interconnection of a mounting frame. Nevertheless, a gap which is desired for installation and aesthetic reasons is produced in the sides of the office cabinet. Due to the outside cladding of the sides, the mounting slots or similar mounting devices required for mounting shelves can be made directly in the inner side pieces and still remain invisible through the outer side pieces, such that a satisfactory interior design is guaranteed and, furthermore, the office furniture according to the invention is also satisfactory in aesthetic terms in its outer appearance. <IMAGE>

Title: Discharging circuit without significant losses for symmetrically arranged electronic switches in branched pairs
Inventor: VOGELMANN HEINRICH
IPC: H03K17/66
Filed: 1985-06-20
Abstract: A circuit which considerably reduces the connection and disconnection losses of controllable switches is specified for self-commutated four-quadrant power converters, which are mainly used to supply three-phase motors and direct current actuating drives. The energy stored in the fundamentally necessary disconnection discharge capacitors Ca1 and Ca2 and the connection discharge chokes L1 and L2 is transferred by the circuit without significant losses to two voltage sources Ur1 and Ur2, which are capable of negative feeding. Because of the short oscillation times in the circuit, clock frequencies of up to 20 kHz can be achieved. The circuit is particularly suitable for multiple-motor drives with bipolar transistors as electronic switches, since the voltage sources Ur1 and Ur2 can then be used in common for all branched pairs. <IMAGE>
Patent DE-3523369-A1 (DE)
Title: Four-pole network for current limiting
Inventor: KRAHL BURGHARD
IPC: H02H9/02
Filed: 1985-06-29
Abstract: In the case of the proposed four-pole network for limiting the current through a load resistor, a transistor is connected in the longitudinal branch of the four-pole network. A further transistor is opened by the voltage drop on a measurement resistor, which is likewise connected in the longitudinal branch. The opening of the further transistor is linked to blocking of the transistor located in the longitudinal branch and hence to current limiting. The connection of the pick-off of a voltage divider - which is connected in parallel with the collector-emitter junction of the transistor in the longitudinal branch - to the base of the further transistor leads to a recursive output characteristic of the four-pole network. In consequence, the power loss of the four-pole network in the event of a short-circuit on the output side is considerably reduced.

Title: Safety device on the feed drum for monitoring the double-sheet monitoring apparatus
Inventor: JENTZSCH ARNDT DIPL ING
IPC: B65H7/12
Filed: 1985-09-23
Abstract: The invention relates to a safety device on the feed drum for monitoring the double-sheet monitoring apparatus on sheet-fed printing machines. The aim of the invention is to provide a safety device with which, in the event of unnoticed failure of the double-sheet monitoring apparatus, the feeding of double or multiple sheets into the printing machine is prevented and machine damage is thus avoided. The object of the invention is to develop a safety device with which the sheet transport on the feed drum is monitored for double or multiple sheets and the setting thereof is coupled to particular paper thickness with the top-lay setting. According to the invention this is achieved in that, to a known linkage mechanism for setting the gap between the top lay and feed table, there is coupled a second linkage mechanism which executes virtually the same regulating paths as the first linkage mechanism and whose final link, designed as an angle lever, is provided with a limit switch which interacts with the grippers of the feed drum and is disposed in the main circuit. The first linkage mechanism and the second linkage mechanism are designed such that, with central setting by the regulating spindle, the distance change of the top lay and of the limit switch are the same. <IMAGE>

Filed: 1985-12-21
Abstract: Handling for the user of nipper pliers with two handle legs (11, 12), each with a jaw (14, 15), which are connected operatively by means of a joint (13) is optimised and improved by an ergonomic design of the handle legs (11, 12). This is achieved in that the handle legs (11, 12) are opposite one another elliptically at the lower end, in that the handle legs (11, 12) are elliptical along the coupling faces with the hand and with the fingers, and in that the handle legs (11, 12) have an elliptical cross-section in the region of the coupling face with the hand. The advantage of this design of the hand side of the nipper pliers is that, for all uses, the handle legs (11, 12) are as closely matched as possible to the anatomy and anthropometry of the human hand. <IMAGE>
