Title: Single lever water mixing valve - has stop ring on guide member limiting rotation in temp. increasing direction
Inventor: ZWINK HELMUT
IPC: F16K31/60
Filed: 1978-04-13
Abstract: The single-lever mixing valve has a guide member turning in a housing and coupled to the control members, while a setting shank pivots on the guide member and turns with it. Turning the guide member alters the temperature of the mixed water emerging, while the shank controls its quantity. A stop ring (10) fits in various angular positions on the guide member, and once fitted cannot turn on it. This has a first radial stop face (23) working with a radial stop face (12) on the housing (1) to limit rotation of the guide member in the temp. increasing direction.

Patent DE-2821400-A1 (DE)
Inventor: HUMMEL JAN
IPC: A01N43/30
Filed: 1978-05-16
Abstract: For temporarily buffering serial bit sequences of asynchronous start-stop signals with different reception and transmission speeds, in order to achieve delay times which are as small as possible, there are in a read-write memory (1) cells for the storage of serial information bit sequences of an output pointer and of an input pointer to realise a pushup storage function. The position of the start pulse of a signal written in by means of the write-in pointer (EZ) is determined by an information store adjusting device (3), a masking device (4, 5, 6) and a start pulse detection device (7, 8, 9) with a priority encoder (7). The output pointer (AZ) is adjusted to the position of the start pulse by means of a part (10, 11) of an output pointer adjusting device (10, 11, 12). Once a filling level of the read-write memory (1), predetermined by a part (4) of the masking device (4, 5, 6), has been reached, reading out is initiated by further displacing of the output pointer (AZ) by means of another part (11, 12) of the output pointer adjusting device (10, 11, 12). <IMAGE>
Patent DE-2822976-A1 (DE)
Title: Lubrication system for IC engine - has wide overflow pipe between sump and container to equalise pressures
IPC: F01M11/00
Filed: 1978-05-26
Abstract: The engine has an additional oil container (8) beneath the crankcase sump (4). Oil returns to the sump by gravity from the bearings and there is an overflow pipe (2) from the sump to the additional container. The crankcase has a relief valve operated by differential pressure so that the air pressure in the sump fluctuates above and below atmospheric pressure. The overflow pipe has a cross section larger than that needed for the oil flow. The top (9) of the pipe is inclined so that oil enters at one side (10) only. This allows air to flow backwards and forwards between the sump and container and prevents emulsification of the oil.

Title: Clock controlled power pack - has auxiliary control circuit regulated by low-pass filter inductor current and connected to switch
Inventor: TENDULKAR GAUTAM
IPC: H02M3/137
Filed: 1978-05-29
Abstract: A DC voltage is applied to the powr pack input terminals to which a switch and a low-pass filter shunted by a free-wheel diode are connected. The low-pass filter is connected to the output terminals. Its output voltage serves as a regulating voltage for a control circuit which delivers the control signal for the switch. The low-pass filter output voltage is the actual value of a voltage controller whose output signal is applied together with a control variable to an auxiliary controller whose output signal is the control signal. The auxiliary controller (RG2) is a current controller controlled by the current in the low-pass filter inductor (L). This controller, the inductor (L) and switch (Thy) form a control path with low time constant.

Title: Pneumatic conveyor system for cement etc. - has setting regulator controlled by pressure in air and material supply pipes
IPC: B65G53/66
Filed: 1978-12-08
Abstract: The system conveys under pneumatic pressure liquid or party building materials, e.g. mortar, from a vessel used in mining and tunnelling. The vessel outlet is shut-off by flap valve, or other suitable fitting. The valve works in conjunction with a double-acting pneumatic cylinder (33), whose pressure chambers are supplied by a setting regulator (19). The latter is controlled by a differential signal resulting from the pressure in the air supply pipe (9) and that in the pipe (11) through which the material is delivered. If the vessel outlet has a rotary flap valve, its shaft carries a vibrator and is coupled to a setting piston extension.

Title: Washing appts. for skis - uses water jets to remove dirt and hot air blast to dry (NL 24.7.79)
Inventor: MISIC PETER
IPC: F26B3/04
Filed: 1979-01-18
Abstract: Washing appts. for skis consists of a tube (1) of rectangular cross-section with a height slightly greater than the width of the ski.

Title: Prestressed silicate glass pane having slight convexity - deformed in bending press contg. spherically curved top die
Inventor: SCHEUFEN HUBERT
IPC: C03B23/031

Title: Electronic binary adder circuit - process commences with higher order digits to achieve fast execution cycle
Inventor: HOELZLE JOSEF
IPC: G06F7/50
Filed: 1979-01-23
Abstract: A digital binary adder is designed to provide fast execution times. The process considers two multi digit numbers (Am, A7-1, ----A1) and (Bn, Bn-1......B1) where n = m. Unlike previous designs the process commences with the addition of the most significant digits and continues down to the least significant pair. Considering two specific digits Ai and Bi, if the result of the addition (ai+bi) does not generate a carry, then no correction is required to higher order digits. If a carry is generated then all higher order results must be corrected. The basic circuit consists of AND gates (e.g. U22) and exclusive-OR gates (e.g. E22) operating as half adder units. As the bit positions increase in order to significance the number of half adder stages increases to accommodate corrections as a result of carry-bits generated in the lower positions. The circuit includes a shift-register, with a half-adder (HA) and a number of flip-flops (FF1, 2, 3, 4, 5).
