Patent DE-3842988-A1 (DE)
Title: Gear pump
Inventor: SHUKLA PRABHAT NARAYAN
IPC: B29C48/38
Filed: 1988-12-21
Abstract: In the invention, the conventional gear pump with two gears, in which one gear drives the other gear via the meshing engagement and the contact between the gear teeth, is modified to the effect that double gear spindles are used so that each gear is driven independently with one and the same torque, and that the gears are closely adjacent to one another, with the result that the gears interlock but in essence do not touch one another.

Title: Switchable serial addition-subtraction circuit for BCD-8421-coded decimal numbers
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1988-12-30
Abstract: The serial addition-subtraction circuit according to the subject of the invention has a dual full adder-subtractor (1), which can be switched from addition to subtraction and vice versa, and a two-value correction circuit (5), using which the number 6 (LHHL) or the number 10 (HLHL) can optionally be added to the intermediate result number which is stored in the shift register (3). In the case of addition, if the sum of the two BCD-8421-coded decimal digits is greater than the number 9 (HLLH), the number 6 (LHHL) is added in circuit (5) to the intermediate result number which is stored in the shift register (3). In the case of subtraction, if the number 0 (LLLL) is underpassed, the number 10 (HLHL) is added to the intermediate result number which is stored in the shift register (3), and thus the same is achieved as by subtracting the number 6. The adder circuit (5) consists of five dual half adders (24 to 28). <IMAGE>

Title: Solidifying and utilising sewage sludge as soil improver - by mixing with absorbent fibrous waste material, pressing into blocks and drying
Inventor: ROLAND ROLF E
IPC: C02F11/12
Filed: 1989-06-10
Abstract: The sludge is mixed with an absorbent fibrous material contg. cellulose before being further treated.  The fibrous material is derived from cellulose materials from a waste material treatment system. The mixt. of sludge and fibrous material is pressed into rectangular blocks with or without surface grooves, or into cylindrical, spherical or pyramidal blocks which are easily stacked or piled. These blocks are then dried. The appts. used consists of a mixer, a press and a dryer.  If the resulting material is to be used as a fertiliser, the press can in some cases be omitted. The grooves in the rectangular blocks serve to allow circulation of air during drying. USE/ADVANTAGE - This invention is used in the disposal and making use of sewage sludges. An economical procedure is provided for drying and solidifying sludge using waste cellulose-like materials. Comparatively little energy is used, and the cellulose material is rendered incombustible by the process. The resulting material can be conveniently dumped, or can be used as a soil improver, in which application its stable structure is of advantage.

Title: Overvoltage protection circuit for dynamo-using appliance - has two freewheeling voltage sources of different strength connectable to short circuit by overvoltage detector
Inventor: STOLL BERNWARD
IPC: H02P9/10
Filed: 1989-09-08
Abstract: The protection is effective in the instance of a load drop.  The circuit has a switch controlled in pulse operation in dependence on the dynamo voltage. The switch disconnects and excitation coil of the dynamo from the operaitonal voltage in case of an overvoltage. A freewheeling diode forms a freewheel voltage and is used for short circuiting the disconnected excitation coil. A freewheel voltage source supplies a second freewheel voltage higher than the first one and is connectable into the short circuit of the excitation coil (1) on load drop via an overvoltage detector (8). Thus the excitation coil is supplied with a second freewheel voltage, opposing the disconnected excitation voltage. ADVANTAGE - Reduction of excitation current in the excitation coil on overvoltage without increasing lossy output in  dynamo normal operation.

Title: Bilge pump operating on water jet pump principle -  with jet of water being generated by forward motion of ship
Inventor: REHLING CHRISTOF BERNHARD
IPC: B63B13/00
Filed: 1991-02-09
Abstract: A device for pumping out water from the bilge of a ship operates on the principle of the water jet pump. The device consists of a housing (3) fixed to the floor of the bilge or to the underside of the ship. The housing (3) has an inlet (8) for the bilge water and encloses a nozzle (9). The nozzle (9) is connected to an inlet pipe (5) which extends in the forward direction and passes through a hole in the bilge floor. The housing (3) has an outlet (7) which is connected to a venturi (13) and an outlet pipe (14). The forward motion of the ship causes water to flow into the inlet pipe (5) and through the nozzle (9) where a low pressure is created which causes the bilge water to flow into the housing and then to be ejected by the jet of water from the nozzle through the outlet pipe (14). USE/ADVANTAGE - Bilge water pump which does not require a separate source of operating power.
