Title: Programmed control system for windscreen washer wiper - operates with variable programme and failsafe manual by=pass
Inventor: DEGWERT HARTMUT DIPL PHYS
IPC: B60S1/48
Filed: 1976-09-20
Abstract: The wiper and wash control for the vehicle has an improved electronic control is which two or more programmable modes of washing and wiping are provided so that the driver has maximum attention to the driving while ensuring a clear windscreen. For normal cleaning the washer switch is briefly pressed to operate the washers are wipers for a limited period. Longer application of the was button sets a longer programme in which the wash and wipe action is repeated for a set number of cycles. This enables the driver to preset the cleaning process while overtaking. The circuit includes four transistors (T1 to T4).

Title: Crane lighter buoyancy system - has supplementary tanks coupled to bow and stern during transit and manoeuvred by pumping out and flooding
Inventor: TAX HANS
IPC: B63B35/44
Filed: 1976-10-04
Abstract: The crane lighter has detachable supplementary buoyancy tanks and a jib (14) overhanging one end (12) of the rectangular pontoon hull (10). At this end, provision is made along the sides (26, 28) for securing supplementary buoyancy tanks (30, 32) if necessary to increase the crane lift. Connecting fittings are such that they are engaged or disengaged by pumping out or flooding tanks. When not in use the tanks are secured to the pontoon ends, or both to one end, to support the lowered jib. To improve pontoon handling in this condition, one or both tanks can have a partially sloping bottom.

Title: Electric pulse counter with bistable stages - resets counter to initial reading when complementary reading is reached by use of chain of electronic stages
Inventor: REINER ROBERT DIPL ING
IPC: H03K23/66
Filed: 1976-12-14
Abstract: The counter has a counting chain consisting of bistable electronic stages controlled by pulses applied to the counting input. When a pulse is applied to the counting input, at least the first switching stage changes its state, thus changing the counter reading by one binary unit. Each second change of each stage causes a change in at least one following stage, or a corresp. resetting of states of the stages resets the counting chain to a certain initial state (A). Starting from an individual counter reading (A) and a complementary reading (B), when a number (C) differing from (B) by at least one binary unit is reached, the counter is automatically set to the reading (B) and also the counter is prepared to be reset to the state (A) by a following pulse.

Title: Mfr. of paint brush with plastic holder - in which bristles are placed in end of mould and plastics injected into mould
Inventor: WITTE WALDEMAR
IPC: A46D3/00
Filed: 1977-03-08
Abstract: Mfr. of brushes, esp. paint brushes, orthe bristle components of such brushes consists of forming a package of bristles and pushing it into the end of a mould. A plastics material, esp. foaming plastics, is then forced inside the mould, surrounding the root of the bristle packet in all regions except for a short length near the mouth of the mould. In this short length, direct contact between the plastics and the bristles is prevented. A plastics block may be formed around the root of the bristles before being introduced into the mould, so that it is bonded to the remaining plastics forming the paintbrush handle. By protecting the outermost region of the bristles near the mouth of the mould from contact with the plastics forming the casing to the bristles, an exact boundary to the end of this plastics is defined and strands of plastics material do not extend along the package or bristles, detreacting from the appearance and resilience of the brush.

Title: Magnetic head with cassette scanning sound - applies along several tracks and has head mirror equal to tape width and motion symmetrical to pole mirror
Inventor: CHRISTIAN ERNST DR
IPC: G11B5/55
Filed: 1977-05-24
Abstract: The magnetic head is operated in conjunction with a cassette with sound recording to record or scan several soundtracks simultaneously. The magnetic head can be adjusted at right angles to the direction of motion of the tape and can be in at least two positions where it can scan the entire width of the tape. The length of the head mirror (3) is approximately equal to half the width of the magnetic tape. It can move in a direction at right angles to the direction of motion of the tape and can traverse at equal distances below and above the pole mirror (2). Depending on the number of tracks to be scanned, it comprises magnetically active core surfaces consisting of one or more systems. The non-magnetic part is subjected to twice the wear as the material from which the pole mirror is mfd.
Patent DE-2728155-A1 (DE)
Title: Blocking mechanism actuating seat belt spool shaft - has resilient circular segment which can dislocate spool shaft from centre
Inventor: ADOMEIT HEINZ-DIETER DIPL ING
IPC: B60R22/34
Filed: 1977-06-20
Abstract: The design proposes a seat belt end fixing to the retractor mechanism spool which prevents the complete uncoiling of the strap and hereby the final maximum impact stress on the spool shaft. The spool body(10) has a flattening(34) on which a circular segment-shaped part(48) is screwed-on. The two parts serve as a clamping assembly for the seat belt end(44). The seat belt then is led around rounded corner(36) of the spool body(10) and along a further flattened surface(30), around the circular part(38), circular part(52) of segment(48), and circular part(70) of segment(30) to the straight section of the seat belt. In uncoiled condition the spool takes up several windings of the belt on the basically circular surface. However when the windings are spent and the seat belt arrives at the lip(72), further uncoiling produces a reactionary force against the rotation, spool shaft(16) is shifted from its centre position and the dislocation engages the blocking mechanism which prevents further uncoiling of the belt.

Title: Analogue indicator with nematic cell plate - has display regions activated successively by matrix switching circuit
Inventor: BECK GUENTER
IPC: G01R13/40
Filed: 1977-06-25
Abstract: An indicator device consists of a plate-shaped nematic cell on one side of which are deposited indicator tracks of 0-59. On the other side, concentrically arranged, are a second track, a minutes track and an hours track. The various tracks consist of transparent conductors which terminate in connecting pads on the outer edge of the indicator. The seconds, minutes and hours tracks are successively activated during each seconds pulse. During the seconds activation period, the corresponding region of the 0-59 track is activated. During the minutes activation period, the seconds and minutes signals are switched to the corresponding region of the 0-59 track. During the hours activation period, the seconds, minutes and hours signals are switched. The basic principle may be used to provide an analogue display of other digital parameters.

Title: Electric motor driven compressor for refrigerator - has regulator for motor speed ensuring constant refrigerant flow rate
Inventor: SCHELAUSKE PETER J DIPL ING
IPC: F25B49/02
Filed: 1977-08-27
Abstract: The performance of refrigerator electric motor driven compressor is adjusted when the refrigerant temp. falls. The performance of the compressor is controlled by its driving electric motor speed. When the temp. and the mass flow rate decrease then the motor speed is increased and vice versa. The motor speed is increased as reciprocal of the decrease of mass flow rate. The regulator uses sensors responding to refrigerant pressure or temp. at the compressor inlet.
