Title: Four:stroke reciprocating engine - has connecting rods acting on cam track in rotary element on output shaft controlling valves
Inventor: FELITHAN WERNER
IPC: F01B5/00
Filed: 1976-02-25
Abstract: The four-stroke IC engine is of the type having a combustion chamber with reciprocating pistons and controlled inlet and exhaust ports, and connecting rods linked to the piston, whose free ends are coupled to means converting the pistons movement into rotation of the output shaft. The con-rod ends engage a cam track which is connected with a guide element controlling the opening and closing of the ports and rotating with the shaft. The element has its axis of rotation radially displaced relative to the longitudinal axis of the combustion chamber and is rotatable relative to the combustion chamber housing. The cam track has at least two portions covering the entire expansion stroke and the entire inlet stroke of the pistons and, between these portions, further portions which return the pistons to top dead centre during the exhaust and compression strokes.

Title: Meter circuit with extended range - has shunt diode and resistor to vary operating characteristic over initial part of meter range
Inventor: SEYFARTH PAUL DIPL ING
IPC: G01R15/00
Filed: 1976-12-24
Abstract: The circuit for extending the initial part of the operating range of a meter comprises a resistor (R2) in series with a rectifier diode (D5) connected in shunt with the meter. A direct voltage -U2 biases the rectifier diode by means of a Zener diode (Z) and resistor network (R3-5). When the input voltage to the transformer (u) is low, the shunt rectifier diode is non-conducting and the meter reading remains proportional to the output voltage of the rectifier bridge circuit (D1-4). As the output voltage of the bridge reaches the threshold value (U2) so the shunt diode (D5) becomes conducting and the meter is effectively shunted by the resistors in series with the diode (R2+R5).

Title: Multi-purpose serving trolley and room heater - has convector plates forming side walls of trolley supporting hot plate
Inventor: MEYER THOMAS
IPC: F24H3/00
Filed: 1977-01-10
Abstract: The multi-purpose serving trolley has an upper hot plate (10) and an additional room heating system formed by plate-like convectors (7, 8) which form part of the side walls (6, 7, 8) which define a storage space beneath the hot plate. The outer surface of the convectors which emits the heat forms a flush connection with the peripheral edge of the hot plate (10). The trolley can be box-shaped in which case the convectors are provided on two adjoining side walls or can be circular where the convectors are fitted over between 50% and 70% of the periphery. By forming part of the side walls the convectors take up no additional space. The vertical convectors produce an upward h ot air current which carries along the hot air above the hot plate so that the latter is kept fairly cool where there are no articles being heated.

Title: Dynamic sound reproduction system - operates by splitting sound into its elements of tone and melody using moving reference point
Inventor: HUEBNER PETER
IPC: H04R3/12
Filed: 1977-02-09
Abstract: A dynamic acoustical system is used giving different tone elements of a sound in a room in different time spans so that it is possible to produce, record, relay and reproduce these dynamic room acoustics. The division of the tone into its elements occurs by changing the amplitude characteristics by the stimulated movements of a reference point. The system requires the composition parameters such as tone and melody tobe acoustically separated, synchronously recorded and taken to the separate channels of a sound carrier for the division of sound. These sound elements are used as mono signals.

Title: Mixer tap with rotationally symmetrical body - has outlet pipe extended centrally through mixer body
Inventor: KRIPPENDORF MANFRED ING GRAD
IPC: F16K11/20
Filed: 1977-02-26

The outlet pipe (2) has a contact surface (8) with the tap body eccentric to the main vertical axis, preventing rotation. Supply of water from the mixer body (1) to either the outlet (2) or a spray hose (15) is selected by a manual valve with pistons (7) which regulate the flow through a rear orifice (4). The rotationally symmetrical form of the mixer body permits surface finishing and polishing by machine.
Patent DE-2709597-A1 (DE)
Title: Groove spacing control in stereo disc recording - uses amplitudes of recorded and adjacent signals for obtaining control signals for drive motor
Inventor: KERN OTMAR
IPC: G11B3/00
Filed: 1977-03-03
Abstract: The process is used in the groove cutting in the record disc production. In this way the centre distances of adjacent spacing of the grooves, carrying signal recordings, are controlled. The control uses simultaneously the amplitude of the signal to be recorded and the signal amplitude of the adjacent, previously recorded groove. The recording element is driven by a motor, controlled by a signal which is obtained by automatic adding of opposite modulation signals. Thus the proximity of the modulated grooves is obtained, which does not exceed the premitted minimum spacing. If a two-component recording is used, the outer edge of the groove modulating signal (right channel) is undelayed, while the inner edge of the groove modulating signal (left channel) is delayed. The two signals are used for generating the control signal.

Title: Safety interlock for fitting seat belt - with pressure switch in squab and switch in clasp
Inventor: HOEFER BERND
IPC: B60R22/48
Filed: 1977-04-16
Abstract: The seat belt system is interlocked with a warning circuit which operates if the belt clasp is not fastened. The circuit incorporates a switch (13) inside the seat, so that if the seat is occupied the alarm is primed. A time delay operates on the warning so that the warning does not operate until the driver has time to enter the car and fit the belt. The warning can be either optic or acoustic.
Patent DE-2717497-A1 (DE)
Title: Waste bin with built-in fire extinguishing device - has cistern with air-locked outlet pipe-closed via spring loaded cap with fusible material
Inventor: LEMKE HORST
IPC: B65F1/14
Filed: 1977-04-20
Abstract: The casing (2) of the bin has a pocket-type emptying space and a water-filled cistern (1) on top. The cistern can be refilled through a filler opening closed up with cap (4). In one corner of the cistern base the outlet pipe (6) terminating in outlet orifice (7) above the emptying space is provided. The outlet pipe is mounted with a rising pitch towards the outlet orifice, so that when the cistern is filled, an airlock forms in the portion of the outlet pipe near to the orifice. The orifice is closed by a cap (8) fitted to the pipe by an easily fusible compound. When fire starts in the bin, the accumulated heat melts the compound, the cap drops off and the outflowing water extinguishes the fire.

Title: Electronic dishwasher water pressure control - involves pulse sequence produced by oscillator and fed to motor to regulate speed
Inventor: SCHMID JOACHIM
IPC: A47L15/42
Filed: 1977-05-10
Abstract: The dishwasher has a washer arm which rotates at a rate depending on the water pressure. The arm is supplied by a water pump driven by an electric motor and the pressure of the washing water can be altered. The electric motor is supplied at a set rate (by an impulse sequence) by voltage time products from the operating voltage supplied from the main source. A time circuit gradually changes over the supply voltage of the electric motor to the operating voltage. The impulse sequence is produced by an oscillator in which an ignition impulse is produced for the variable phase control. The impulse is conveyed to the control electrode of the triac. The motor shaft has a speed indicator with the readings conveyed to the integrated switch circuit.
