Title: Charge injection device sensor for TV receiver - comprises insulating layer capacitors arranged in rows and columns of matrix for interlaced scanning system
Inventor: HERBST HEINER DR
IPC: H01L27/148
Filed: 1976-09-20
Abstract: The substrate (1) carries on its transparent insulating layer vertical strips (2-7) of conductive polysilicon forming rows of insulating layer capacitors. Another transparent insulating layer carries strips (8-11) of aluminium which form a column of insulating layer capacitors. The broader areas (81, 82, 91, 92, 101, 102) which over the gap between the strips (3/4 and 5/6) form each a gate of one of the insulating layer capacitors. Channels on the substrate surface in the gap between strips (2/3, 4/5 and 6/7) are doped in the opposite sense (dotted areas). They act as channel stops. The gate of a second or third capacitor is represented by an area of the vertical strip between two horizontal inversely doped areas.

Title: Floating flood weir system - has float elements on chains to swing across flow when tide is flooding and allowing tidal flow
Inventor: HOPPE HARTMUT DIPL ING
IPC: E02B3/02
Filed: 1976-09-23
Abstract: A flood weir is based for protection against high tides. The floats (4) are joined into float chains which are press-into the form of a floating dam when the tide is flooding (7). The dam is re-opened by the ebb flow. The float chains can be anchored to a fixed point at their bank-side end. This fixed point can also fulfil the function of a thurst bearing against the flood pressure. The floats (4) can be connected with a bank-side fixed point (6) via anchor houses (8) and in these the dam pressure can be transmitted by tension forces.

IPC: F16J15/34
Filed: 1976-11-29
Abstract: The mechanical seal for a rotating, axially movable shaft is esp. for heavy duty shafts subjected to thermally-induced longitudinal expansion e.g. alternating current generating machines. One sealing element (3) is mounted on the shaft and rotates with it. A threaded nut (5) on the shaft presses the seal against a shoulder (6) on the shaft. A sealing ring (8) of a stationary sealing element (7) is pressed against the rotating sealing element (3) by a spring (9). The fixed seal is held by a support ring (12) which is movable axially with the shaft. The support ring is prevented from rotating by several holder pins (24) between the housing (1) and ring.
Patent DE-2702264-A1 (DE)
Inventor: KLEEB MARKUS
IPC: H01H13/50
Filed: 1977-01-20
Abstract: Said switch is intended to be usable both for the selective connection of individual conductors or for soldering into circuit boards. It has a housing (2) in which switching contacts and an axially displaceable plunger (3) are arranged. The switching contacts are connected to solder tabs (11, 13, 14) which are distributed over the circumference of the housing (2) and project out of said housing (2). Adaptors (21, 31) which have an annular insulating body with a quadrilateral outline can be plugged onto the housing (2). The insulating body has contact springs on the inside, which contact springs make contact with one of the solder tabs (11, 13, 14) when the adaptor (21, 31) is plugged on. The contact springs are integral with pins (25, 35a, 36a) which all project out of the adaptors (21, 31) from the same quadrilateral side of them. When the adaptors (21, 31) are plugged onto the housing (2), the pins (25a, 35a, 36a) can be soldered into a circuit board (19). The push-button switch can, however, also be used without the adaptors, individual electrical conductors then being soldered directly to the solder tabs (11, 13, 14). <IMAGE>

Title: Test rollers for vehicle brakes - have revolution counters to measure change in wheel speed when braking
Inventor: BEISSBARTH OSMOND
IPC: G01L5/28
Filed: 1977-04-26
Abstract: The vehicle braking testing device has two rollers(1, 2) coupled together by a chain(4) and driven at the same speed by a motor(3) mounted on a shaft(5). The two shafts(5, 6) of the rollers are respectively positioned on needle or roller bearings on mounting blocks(7-10). The shaft(6) of the second cylinder carries a lever(12) connected to an operating cylinder(13). Two arms(14, 15) couple the shaft(16) of a freewheel cylinder(17) to the shaft of the second cylinder. So that the shaft of the freewheel cylinder clears the coupling chain(4), auxiliary chain guide wheels are provided. The speed of rotation of the freewheel roller is measured with a first revolution counter(22) and that of the driven rollers with a second rev. counter(25). In operation, a vehicle wheel is mounted on the driven rollers(1, 2) and the change in speed of rotation during braking is measured.
Patent DE-2722176-A1 (DE)
Title: Compression ignition engine with working piston - has auxiliary piston in bore in working piston crown to absorb peak pressures
Inventor: JESINGHAUS JOCHEN
IPC: F02B57/00
Filed: 1977-05-17
Abstract: The compression ignition engine piston crown has a bore which is closed by a flexible metal diaphragm. The bore is subject to gas pressure equal to or slightly less than the working pressure. The diaphragm will move towards the bore should the working pressure exceed the normal and thereby increase the combustion chamber volume. an alternative design employs the same principal by using a sprung plunger in place of the diaphragm. The plunger absorbs excess energy and returns it at the end of the combustion stroke. The pistons of a rotating double cylinder engine could have similar auxiliary pistons actuated by centrifugal force. Each auxiliary piston contains a fuel injection plunger fed by a fuel bore passing through the working piston as far as the centre shaft to joing a main fuel feed.

Title: Monitor for self-focussing lens - has reference sensor and phase-detecting comparing circuit
Inventor: KOENIG GOTTFRIED DIPL ING DR
IPC: G02B7/36
Filed: 1977-06-04
Abstract: The monitor allows the camera lens position to be adjusted according to a measurement of the brightness distribution in a plane which the light reaches through an aperture. An additional measurement is made in a plane optically equivalent to that containing the aperture. Each measurement is made using a set of photo-sensors. The sensors of the two sets are compared one-to-one in a phase detector circuit to control the adjustment of the lens position. Each set of photo-sensors pref. forms a circle centred on the optical axis. The one-to-one comparison is initiated from a ring-counter. The photo-sensors are photocells forming part of a monolithic integrated circuit.

Title: Chrominance signal suppressor in TV transmitter or receiver - has amplitude filter, second filter passing only colour information, and switch and threshold unit
Inventor: WEISS CHRISTOPH DIPL ING
IPC: H04N9/70
Filed: 1977-07-08
Abstract: The video signal has a low colour information content, and is esp. a black-and-white picture signal. The colour burst is filtered out from the composite signal (FBAS) using an amplitude filter (AS). The chrominance signal at the output of the filter (F) is passing only the colour information obtained during a burst, is suppressed in a first switch by interruption of a wire (S1) running to a threshold unit (SB). The rest of the colour information is evaluated for its amplitude in the threshold unit (SB), and when the amplitude is below the threshold, picture colour transmission is blocked.

Title: Dust-laden gas filter - with wedge shaped filter bags for better back flushing efficiency
Inventor: HOELTER HEINZ
IPC: B01D46/02
Filed: 1977-09-01
Abstract: In a filter assembly for dust-laden gases the bag filters are not designed in the convention round or rectangular shape but wedge-shaped. This doubles the cross-sectional area available for the incident gas flow. The reduced incident velocity results in a better backflushing efficiency. The filtering action is also improved.
