Title: A=D converter for signal processing network - uses analogue frequency evaluation and digital correction of quantisation errors
Inventor: BOEHME ROLF DR SC TECHN
IPC: H03M1/00
Filed: 1979-11-23
Abstract: The A/D converter includes an analogue circuit for frequency evaluation with one or more sample-and-hold devices. This circuit is coupled between the signal input and the input of the A/D converter with a digital processor, allowing digital correction, connected after the latter. The analogue signal converts the spectrum of the analogue input signal to bring it within the optimum handling range of the A/D converter, the frequency characteristic of the analogue circuit determined by the characteristics of the analogue signal. The sample-and-hold devices prevent any variation in the analogue signal value at the output of the analogue circuit, during the conversion time of the A/D converter.

One of the two, at least, has a connecting device permitting assembly of the components in a prescribed mutual position, of T-shaped cross-section. This can be made in flat mat shape, and easily transported, for quick conversion to a T section.
Patent DE-2948770-A1 (DE)
Title: Data packing circuit for variable-length data - has memory, two shift register, logic and two counters coping with fixed word length format
Inventor: SARAN AMITABH
IPC: G06F7/76
Filed: 1979-12-04
Abstract: The data packing circuit has an m-bit-per-word memory to store and output data words of variable length, where the m bits contain a data word of variable length, unused bits and a limiting bit to mark the boundary between data word and unused bits. An m-bit shift register receives the output of the m-bit memory in parallel. An n-bit shift register receives the contents of the m-bit register serially. Logic prevents unused bits and the limiting bit being loaded into the n-bit register whilst bits are being shifted out of the m-bit register. A counter counts the bits left in the m-bit register and releases the memory for loading the next m-bit word into the m-bit register after this register's previous contents have been shifted out completely. A second counter co-operates with the n-bit register in the same way.

Title: Microphone arrangement for noisy environment - uses motor-driven movement of microphone mouth mask during speech periods
Inventor: HANNI MANFRED ING GRAD
IPC: H04R1/08
Filed: 1979-08-03
Abstract: In very noisy environments, the use of well-fitting mouth masks containing a microphone is known but constitutes an inconvenience. The appts. is arranged with a double microphone (DM) and adjacent mouth mask on a suspended arm (HB) which has a worm wheel (Z) pivoted at a point (DL2) above the microphone. The worm (Sch) is fitted to an axle (W) of a fractional horse power motor (M) which can be marginally turned around another pivot point (DL1). When the speech key (Ts) is despressed, a capacitor (C) discharges through a solenoid (HM) causing the worm gear to disengage from the wheel (Z) and permitting the tension spring (F2) to pull the mouth mask (Mk) against a stop (A2) and against the speaker's mouth. Due to the compensating action of the double microphone, it is not necessary to press the mouth mask very tightly onto the speaker's face. When the speech button is released, the motor is switched on to move the mouth mask away from the speaker and allowing him to breath freely.
Patent DE-3000934-A1 (DE)
Title: Laser pulse generating system - discharges pulse of shorter length than pumping pulse through partially transmissive reflector (FI 30.4.80)
Inventor: SUOMINEN OLLI
IPC: H01S3/08
Filed: 1980-01-11
Abstract: A laser material (1) which is optically pumped by a light source (4) is disposed between two resonator reflectors (2,3) one of which (3) is partially transmissive. The dimensions of the laser material and the resonator, and the properties of the reflectors and the length and output of the light pulse, are so selected that the relaxation oscillation can be utilised. This allows the first relaxation pulse to discharge the main portion of the energy accumulated in the laser material as a short laser pulse. The power of the laser begins to increase heavily as the energy in the laser rod exceeds the threshold value of 40mJ. During the time taken for the amplification of spontaneous emission signal, additional energy is pumped into the laser rod. The higher up above the threshold one gets, the more energy will the laser pulse contain.
Patent DE-3009346-A1 (DE)
Title: Proximity detector system with optical input signal - uses variable preset internal frequency to block interference from similar adjacent equipment
Inventor: WERTENAUER HELMUT
IPC: H03K17/94
Filed: 1980-03-12
Abstract: The circuit uses modulated light as the initiating signal in e.g. a system for the automatic flushing of urinals. An oscillator and amplifier, preferably a phase locked loop (1), has two outputs (a,b). The frequency is set by selectable resistor values (8,10). The first output (a) drives (6) an amplitude modulated light source (7). The input signal circuit comprises a photosensitive receiver (3) and an amplifier (2). If light from the emitter (7) is reflected onto the receiver the phase locked loop responds giving an output (b) to a power amplifier (4) which in turn drives the function to be controlled (5). Light of any other frequency does not stimulate any response, thus incident light from a suitably tuned neighbouring installation has no effect, and no optical screening is required.

Title: Inclined staircase lift
Inventor: LANDGRAF KURT
IPC: B66B9/08
Filed: 1981-04-18
Abstract: The invention relates to an inclined staircase lift, consisting of a platform (3') with ramps which can be swung from a bottom approach position into a top locking position. The platform is mounted and is movable in a known manner on a transport device running along a staircase, one barrier (1, 1') each being provided on the ascending side and the descending side. The barrier (1, 1') is mounted on a side wall (2') or the like connected to the platform (3') and can be swung from a vertical, top approach position into a horizontally directed locking position. The essence of the invention consists in the fact that a locking device (2, 14) is provided for each barrier (1, 1') and ramp (16, 16'). The locking device (2, 14) locks the barrier (1, 1') and the ramp (16, 16') against pivoting in the locking position. In addition, an actuating device (17) acting on the individual locking device and neutralising the locking of the barrier (1, 1') against pivoting upwards and the locking of the ramp (16, 16') against pivoting downwards is provided at the individual stops so that, at the individual stops, for example in each case only the barrier and ramp on the ascending side - at the lowermost floor the barrier and ramp on the descending side - can be swung up and down respectively for access to or for leaving a lift car. <IMAGE>
