Patent DE-2639568-A1 (DE)
Title: Filter with frequency dependent transfer function - consists of components with single or multiple gate circuits some of which are affected by propagation time
Inventor: FETTWEIS ALFRED PROF DR
IPC: H03H17/02
Filed: 1976-09-02
Abstract: The filter is for analogue signals present in quantised or coded form. Its components are realised by gate circuits. Starting from a branching off or bridge circuit with reactive components, its reactive or conducting components are in the form of one or two gate circuits respectively, affected by propagation time, while resistive components are in the form of single gate circuits unaffected by propagation time. Non-reactive multiple gate components (transformer, gyrator, circulator) are in the form of propagation time free multiple gate circuits. Adaptors are provided for gate connection in the gate circuits, by which gate impedances are matched to each other. Individual components or individual circuit sections are in the form of multidimensional digital filter networks so that they do not contain delay-free directed loops.

Title: Safety belt with automatic accident release mechanism - has spring-operated unlocking device triggered by certain strain level on belt
Inventor: WIRTH MANFRED
IPC: B60R22/32
Filed: 1976-09-11
Abstract: The safety belt is provided with an automatic accident release mechanism which is triggered by the heavy strain applied in an accident. The strain on the belt must first reach a certain min. force so that the belt does not open every time it is stressed. This can be achieved by an attached wire that expands to a leaser degree or by a small curve in the belt stretched flat by the stress and triggering a mechanism that operates the unlocking button. The lock can be open, e.g. by a bolt which is depressed by a spring mechanism, wherein the strength of the spring can determine the strength of the strain on the belt. The mechanism can be so adjusted that the belt only opens after a certain number of seconds following impact.

Title: Safety pneumatic tyre is filled with balls - contg. air or foam to give continued running after puncture
Inventor: VESTER GERHARD
IPC: B60C5/00
Filed: 1976-10-28
Abstract: A safety tyre is of conventional body construction and contains stable balls, filled with air or with plastics foam, these balls are of elastic material, such as rubber or the same material as the tyre itself. The tyre is also inflated or may be completely filled with the same foam material. The tyre will not collapse on a sudden burst, thus causing risk of an accident.

Title: Transfer line for machining long workpieces - has walking beam transporters loaded by roller tables arranged in parallel on each side
Inventor: JUNG GEB STROMBERG RUTH
IPC: B23Q7/05
Filed: 1976-11-30
Abstract: The transfer line for continuous machining of long sections and tubes consists of pairs of walking beam transporters, arranged between parallel roller tables. Stops at the end of the roller tables ensure that the transporters move the workpiece correctly into the processing machines between the roller tables. A workpiece can be split exactly into halves and is finally deposited in a storage bin. The individually driven rollers of a roller tables receive the long workpieces from a loading devide and take them to a stop. Walking beams transfer them to the first machine. After transfer by the same walking beams to the next roller table, a stop is followed by transfer on walking beams to machine for the other end. The work is taken to a measuring station to set a stop so that the work is precisely halved by the parting saw.

Title: Flue gas analyser - using suction device and several flasks with reagent and indicator
Inventor: TITZE KARL
IPC: G01N33/00
Filed: 1977-03-05
Abstract: An apparatus for the determination of CO2 and other gases, e.g. for the flue gas analysis of heating plant, uses several flasks with reagents through which the gas is sucked and which indicate by the colour change of an indicator additive the reading directly. The flasks are joined by taps which can be opened to mix their contents. This enables even unskilled people to check their own heating installation for efficient combustion. It requires only very simple equipment and ready-made chemical reagents.
Patent DE-2710662-A1 (DE)
Title: Connection for charging battery from load circuit - using nonlinear resistors in series with load and diodes in series
Inventor: KROGE HARRY VON
IPC: H02J7/00
Filed: 1977-03-11
Abstract: The application is typically to the provision of a dc power supply to an electronic circuit functioning together with a load fed from a suitable supply. In order to achieve satisfactory charging of the battery over a wide range of load current, a non-linear resistor is connected in series with the load and the coltage developed across it by the current then used as a source for battery charging. In practice the non-linear resistor consists of diodes in series such that their combined forward voltage drop is slightly higher than the required charging voltage. Further diodes in series with the battery help to regulate the charging process. The circuit can be adapted for use with both ac and dc power sources.

Title: Data processing unit keyboard illumination - using single strip light in retractable reflective holder
Inventor: POTT FRITZ
IPC: B41J29/19
Filed: 1977-04-19
Abstract: A keyboard illumination device for data processing units is partic. applicable to cash registers and accounting machines which may have to be operated in darkened or poorly lit surroundings. It avoids the necessity of individual lamps for each key leading to expensive keyboards, undesired heat generation, and costly illumination level control where required. A holder (4) supporting a lamp (7) and having a reflecting surface (6) may be pivoted out of the body of the unit, thus enabling the lamp to illuminate the keyboard (12). The lamp is of elongated construction and stretches the breadth of the keyboard. The keys may be top coated with fluorescent material.

Title: Vibration generator for compacting device - has phase of two rotary counterweights altered by reciprocating rack and pinion drives
Inventor: FECHTER LEONHARD DIPL ING
IPC: B06B1/16
Filed: 1977-08-11
Abstract: The vibration generator, suitable for compacting materials, has two parallel units (1, 2) rotating in opposite directions. At one end, they are connected by gear pinions (8). Each incorporates a counterweight (16). At the other end, the housing (10, 11, 12) extends outwards forming a hollow sleeve (7) through which each is varied. Inside the sleeve is a sliding sleeve (20) with a helical groove (22) around part of its outside. Attached to the inner sleeve is a control spindle (27) reciprocated by a rack and pinion gear (29, 30). When the two vibratory units (1, 2) are driven from one end (6), the rack and pinion drives vary the position of the counterweights due to the helical groove, which converts reciprocating movement into partial rotary movement.

Title: Safety cover for car bonnet - has deformable foam construction which releases adhesive to grip pedestrians thrown onto bonnet
Inventor: HEISS WERNER
IPC: B60R21/34

Title: Function control for PBX - has hold memory retaining addresses of connection circuits for reconnection when free
Inventor: SEHR WERNER ING GRAD
IPC: H04Q3/62
Filed: 1978-02-27
Abstract: The function control is for the identification of the connection circuit's address and the operator-set's address to allow storage into the hold store and the renewed connection of the operator set as connection circuits become free. This identification process occurs during the formation of outgoing as well as during existing connections between the operator sets and the connection circuits. An optical signal appears at the operator set concerned when that set is reconnected to the connection circuit whose address has been retained in the hold store.
