Patent DE-3120923-A1 (DE)
Title: Glue application device
Inventor: RIESMEIER WILHELM
IPC: B05C1/02
Filed: 1981-05-26
Abstract: In a device for the application of liquid glue to workpiece sides which are continuously conveyed past and onto which an edge strip is adhesively bonded, a glue layer is formed on an application roll. For this purpose, the application roll is arranged upright with a lower part in a glue reservoir, and, by virtue of entrainment as a result of the roll rotation and the accumulation effect in an accumulation pocket adjacent to the roll, the glue is conveyed upwards to a roll upper part which comes into contact with the workpieces. So that the edge strips can also be glued at the same time, an auxiliary roll counter-rotating with respect to the application roll with the same circumferential velocity as the latter is arranged, axially parallel, directly adjacent to the roll upper part of the application roll, of the same height as the latter. At the discharge side of the two rolls, an accumulation chamber, parallel to the rolls, for the glue, is formed by a wall which reaches as far as the two rolls and extends at least over the height of the rolls.

Patent DE-3150441-A1 (DE)
Title: Bucket for a bucket elevator
Inventor: NEUMANN RAINER
IPC: B65G17/36
Filed: 1981-12-19
Abstract: The invention relates to a bucket for a bucket elevator, which has a bucket trough delimited by two lateral bucket end walls. It may arise, especially during the conveyance of adhesive bulk goods, that residues of discharged bulk material remain stuck to the bucket troughs, thus causing a gradual build-up of solidly compacted bulk-material adhesions in the bucket with the repeated operations of ladling and discharge. To avoid this disadvantage, the invention provides that the bucket troughs have a flexible wall region. This wall region, which may consist for example of rubber, plastic, woven fabric or the like, is capable of deforming during the discharge operation, so that adhering residues readily detach and are thus discharged.

Title: Dual circuit motorcar brake system
Inventor: VOLLMER OTTO
IPC: B60T8/18
Filed: 1982-04-08
Abstract: In the case of a motorcar brake system with a plurality of circuits, preferably a dual circuit motorcar brake system with a footbrake valve for controlling the brake pressure in a front axle brake circuit and in a rear axle brake circuit of a motor vehicle, a pressure transducer is separately provided or incorporated in the footbrake valve, by means of which the pressure in the front axle brake circuit can be controlled as a function of a load-related pressure of the rear axle brake circuit; a retaining valve (15; 71) is provided for the compressed air of the rear axle brake circuit entering at the pressure transducer (9) and controlled as a function of the load. The retaining valve comprises a piston and spring arrangement, by means of which the load-related brake pressure entering into the retaining valve is kept constant despite dynamic axle load displacements. Reductions in the rear axle brake pressure caused by dynamic axle load displacements during braking or by a brake force regulator during downhill running thereby do not cause any corresponding reduction in the front axle brake pressure. Such a reduction in the front axle brake pressure is only brought about, deliberately, when a fall in pressure in the two brake circuits is initiated by way of the footbrake valve. <IMAGE>

Title: Circuit arrangement for counteractive gain control
Inventor: RALL BERNHARD DIPL ING
IPC: H04M9/08
Filed: 1982-05-14
Abstract: In a circuit arrangement for counteractive gain control in speech-controlled intercom or hands-free devices in communications systems, use is made of OTA amplifiers whose control inputs are connected via two resistors and into which the adjustable control currents determining maximum gain can flow. These can be reduced in each case by a transistor, one transistor being controlled by a speech-controlled control unit and the other transistor, using a differential amplifier, by the voltage at the connection point of two resistors connected in series between the control inputs of the amplifiers. A negative feedback from the output of the differential amplifier to the transistor controlled by the control unit ensures that the summation amplification of the two counteractively controlled amplifiers always remains constant and its amplification range can be adjusted to the desired extent.

Title: Circuit arrangement for telecommunications switching systems, in particular telephone switching systems, with concentrators with isolated switching operation in the event of functional failure of the concentrator control lines
Inventor: HILLIGES FRIEDRICH
IPC: H04Q3/60
Filed: 1982-06-30
Abstract: In a telephone switching system with concentrators with isolated switching operation in the event of functional failure of the concentrator control lines, the concentrator is connected to the exchange via two separate line systems (G1/g1/G11, G2/g2/G12), each of which provides a control channel in each case for connection of one and the other of two concentrator controllers (KE1, KE2) to the central control mechanism (AST, P, ...) of the higher-order exchange. In the event of functional failure of both line systems (G1/g1/G11, G2/g2/G12) due to interference, the concentrator controllers (KE1, KE2) instigate isolated operation as an emergency measure. In the event of failure of one line system only (e.g. G2/g2/G12), the concentrator controller concerned (e.g. KE2) handles only internal connections within the concentrator, while only the other concentrator controller (e.g. KE1) with the intact line system (e.g. G1/g1/G11) controls external connections. If the concentrator controller (e.g. KE2) with the defective line system (eg. G2/g2/G12) receives connection data of an external connection, it transfers them to a memory (N2); in this operating mode, the other concentrator controller (e.g. KE1) is prompted to interrogate this memory (N2) at regular intervals, to accept connection data and to set up corresponding external connections. A further memory (N1) accepts from the concentrator controller (e.g. KE1) with the intact line system (e.g. G1/g1/G11) connection data for internal connections; the concentrator controller (e.g. KE2) with the defective line system (e.g. G2/g2/G12) retrieves connection data from this memory (N1) at regular intervals and sets up internal connections. <IMAGE>

Title: Ignition system for an internal combustion engine
Inventor: KUGLER KARL-HEINZ
IPC: F02P3/05
Filed: 1982-08-14
Abstract: An ignition system is proposed which serves to ignite the fuel/air mixture compressed in a cylinder of an internal combustion engine. This ignition system contains connected in series - viewed in the direction of the current - the primary winding (5) of an ignition coil (6), the emitter-collector path of a final transistor (7) and a measuring resistor (8). In addition, a control device is provided which serves to keep the amount of ignition energy constant and is connected by its input (59') to the connection present between the emitter of the final transistor (7) and the measuring resistor. According to the invention, the input (59') of the control device is under the influence of an electrical compensation variable which is dependent on the control current of the final transistor (7), and in addition under the influence of an electrical compensation variable which is dependent on the supply voltage. By means of this measure, interference influences which can occur as a function of the current flowing via the base-emitter path of the final transistor (7) and can also occur as a function of fluctuations in the supply voltage are avoided at the measuring resistor (8). <IMAGE>

Title: Control device with elastic feedback
Inventor: THEILMANN HUBERT DIPL ING
IPC: G05B13/02
Filed: 1982-10-21
Abstract: In the control device with elastic feedback, in addition to the manipulated variable y said device is fed a signal corresponding to the variable system amplification of the controlled system at the respective working point and said signal is multiplicatively connected to the output signal of the timing element in the feedback. The system amplification is calculated virtually without delay in a computing circuit from the controlled variable differential  DELTA x and the manipulated variable differential  DELTA yvz which is delayed in a delay element of the first order whose timing constant is equal to the system timing constant. In this way, the controller can always be operated with optimum control amplification even in the event of considerable changes in the system amplification. The control device is mainly used in controlled systems with variable, non-linear system amplification, for example in pressure or flow controlled systems. <IMAGE>

Patent DE-3311727-A1 (DE)
Inventor: FRANK PETER
IPC: G01S7/4865
Filed: 1983-03-30
Abstract: An apparatus for measuring the delay time interval between electrical pulse signals, particularly in conjunction with electrooptical range finders. A coarse measuring counter counts clock pulses from a quartz oscillator during the interval and a fine measuring interpolator determines the residual time from the end of the interval to the next clock pulse. Residual time at the start of the measuring interval is avoided by exactly synchronizating the start of measurement with a timing pulse front (n+2) of the quartz oscillator.
