Title: Variable duration and sequence pulsed data signals evaluation - by using preliminary pulse sequence transmitted prior to main data transfer as reference
Inventor: BEUSS BRUNO ING GRAD
IPC: H04L25/04
Filed: 1978-11-11
Abstract: Signals received via transmission line are evaluated via a control unit connected to the pulsed data signals receiver. Noise -free evaluation of the data signals is achieved independently of the properties of the transmission link. Prior to initiation of data transmission, via differential length and variable sequence pulse-signals, a pulse sequency suitable for use as the basic or fundamental signal is fed into the transmission line, the pulse duration and pulse pauses being shorter than those used during data transfer. This pulse sequence is then measured on the reception side w.r.t. pulse duration and pulse pause evaluated on a 1 to 1 time scale. The measurement results are then digitally stored and used as a reference for subsequent evaluation of the data transmission.

Title: Force measurement device for screws, dowels etc. - consists of radially-expandable, sprung ring between compressing discs
Inventor: GASSMANN HORST-DETLEF
IPC: G01L5/24
Filed: 1979-03-14
Abstract: A force measurement device to screws, dowels, and similar fixing devices consists of a spring element between two discs. It is a simply constructed device giving a direct readout of the stress in the fixing element. The spring element is a radially expandable ring (1). The discs (2) have conical surfaces (2a) sloping towards each other to form a radially increasing gap between the discs into which the ring fits. The inclined surfaces of the discs form slip surfaces for the ring facilitating its radial expansion under increasing compression. As the compressive force increases and the ring expands its ends separate. Indicating devices (3) on the ends of the ring show the degree of separation and thus the compressive force on the discs.

Patent DE-2938095-A1 (DE)
Inventor: BRAUN KURT
IPC: G05B19/07
Filed: 1979-09-20
Abstract: What is proposed is a packaging machine, in which the individual trigger times are determined and controlled electronically by means of an electrical control device. For this purpose, for example, the angular position of a shaft is detected and a signal is read out from a memory according to the respective angle value. For a speed-dependent control of the trigger points, the addresses of the memory are changed. The proposed machine is characterised, above all, by high adaptability to changed conditions, since, in the event of a change, only the memory contents have to be varied in each case.

Title: Hydraulic amplifier for servomotor - uses hand-operated pump as control pressure source allowing variable amplification in dependence on supplied pressure medium
Inventor: KYSTER ERIK
IPC: F15B17/02
Filed: 1979-10-17
Abstract: The hydraulic amplifier for a servomotor has a hand-operated control pump (24) incorporated in the control lines (26,27) for the motor and used to provide a pressure difference.

Title: Flat pouch production and filling method - forms two strips into troughs before joining by lengthwise seams
Inventor: WALTER KURT ING GRAD
IPC: B65B9/04
Filed: 1979-11-10
Abstract: The method continuously produces and fills flat cushion-type pouches sealed on four sides, these being formed by two strips of sheet material joined together. After the filling space has been formed by two lengthwise and on transverse seams, the material is inserted and the filled and sealed pouches are parted off. Before the two strips (1,1') are joined together, they are shaped into troughs to form the filling space (2). They are then joined by lengthwise seams, and after filling and sealing are parted off in the lengthwise and transverse directions.

Title: Phase locked loop circuit - increases locking speed by shunting out low-pass filters resistor during pull-in
Inventor: LIEHN HANS-JOACHIM
IPC: H03L7/107
Filed: 1979-12-20
Abstract: The phase locked loop has a phase detector comparing the phase of a reference oscillator with that of a voltage controlled oscillator (VCO). The detector output is coupled via a low pass filter to the control input of the VCO. A switch (17) bridges or partially bridges the resistor (12) in the low pass filter's (14) RC circuit during the pull-in process. The phase detector (11) has a second output (20) that produces pulses during pull-in and a static signal in the locked state of the loop. The second output is connected via an integrator (18) to the control input of the switch. The loop locks rapidly when used even with an inexpensive low pass filter.

Title: Telephone answering unit with initial start speech detection - uses strict timing circuitry and speech detection to minimise pauses and coordinate incoming call replay record
Inventor: ALBRECHT RUDOLF
IPC: H04M1/64
Filed: 1980-01-31
Abstract: The phone call answering unit with speech detector and time control circuitry eliminates waste of unused storage when recording the message and ensures time to reply is at its most economical commensurate with long distance telephone calls. For recording the local message the equipment uses a microphone (19) and amplifier (17) feeding into a tape recording unit (1) which is switched on by a control circuit (25,13) when the speech detector circuits (21,23) detect commencement of speaking by the user. This eliminates blank tape and wasted time at the head of the message. All pauses during the message are ignored by the speech detector and the tape continues running. For incoming calls through the telephone circuit (5) the tape records as controlled by the control circuit (13) and according to timing signals given by a timing circuit (25) which ensures co-ordination of the replayed message and recorded message.

Title: Test facility for safety circuit operation - allows fault to be simulated to check operation of fault detection circuitry
Inventor: KADELBACH VOLKER DIPL ING
IPC: G08B29/12
Filed: 1980-06-13
Abstract: The safety control circuit is of the type used on a vehicle gear change system to indicate a fault condition and includes a facility for checking the circuit operation. In normal operation, the control circuit (10) provides an output (A) to actuate the power solenoid (12) of the gear change unit.
