Title: Copy transfer for photocopier - applies fine grain opposingly-charged particles over toner image before transfer
Inventor: TANAKA SUSUM
IPC: G03G15/095
Filed: 1980-09-23
Abstract: A copy transfer process for a photocopier applies a layer of fine grain particles to the toner image before the copy sheet is brought into contact. This reduces the residual charge on the toner image and enables simple image transfer. The fine grain particles are charged with a polarity opposite to that of the toner image. It causes the charge image to be swamped so that a simple pressure process transfers the image. The system can be applied to most dry powder copiers.

Patent DE-3103923-A1 (DE)
Title: Process for removing hydrogen sulphide from industrial gases
Inventor: KLEEBERG ULRICH DR RER NAT
IPC: B01D53/52
Filed: 1981-02-05
Abstract: The invention relates to a process for removing the hydrogen sulphide from industrial gases having a low oxygen content, in particular having an oxygen content less than 0.1%. The hydrogen sulphide-containing gas is introduced into a scrubbing tower and is there scrubbed by a Stretford scrubbing liquid containing anthraquinone acids and/or salts thereof. The clean gas is conducted out of the scrubbing tower. The Stretford scrubbing liquid is taken off from a scrubbing tower delay tank fed to an oxidiser into which air is blown. Finally, sulphur is withdrawn from the oxidiser by flotation or the like and fed to sulphur processing, while the Stretford scrubbing liquid is pumped back to the scrubbing tower. In the Stretford scrubbing liquid, thiosulphate is formed during the scrubbing process. In order that interfering losses of the anthraquinone compounds used do not occur and that thiosulphate destruction in the waste water treatment is not required, oxygen is introduced into the hydrogen sulphide-containing gas. As a result, a thiosulphate level of above 15 grams per litre, preferably in the range from 20 to 200 grams per litre, is maintained in the Stretford scrubbing liquid. Surprisingly, interfering losses of the anthraquinone compounds used are avoided in this manner.
Patent DE-3104394-A1 (DE)
Title: Retention device for the winding shaft of a roller blind or the like actuable by a belt
Inventor: SCHMITT MANFRED
IPC: E06B9/86
Filed: 1981-02-07
Abstract: The invention relates to a retention device for the winding shaft of roller blinds which are actuated manually by a belt. In these roller blinds, precautions must be taken in order to protect the lowered roller-blind armour against being pushed up from outside in an unauthorised manner. Corresponding devices for this purpose are known in different versions, but they all presuppose an automatic retention of the winding shaft. The present invention serves this purpose in that there is provided in a cavity (13) of the belt pulley (11) a continuous internal toothing (27) which is normally held by the force of a leaf spring (30) in blocking engagement with a fixed toothed quadrant (29) which is arranged on the lower half of a bearing housing (17) extending into the cavity (13) of the belt pulley (11). When a pull is exerted manually on the belt (12) downwards in the vertical direction, the internal toothing (27) is automatically separated from the fixed toothed quadrant (29), so that the winding shaft (10) is released for a rotational movement in the winding or unwinding direction. As soon as this manual pull is cancelled, the internal toothing (27) is once again brought automatically into blocking engagement with the toothed quadrant (29) by means of the leaf spring (30). For this purpose, a bearing journal (15) for the winding shaft (10) is supported in a ball bearing (16) which is arranged in the bearing housing (17) so as to be vertically displaceable and which is prestressed upwards by the leaf spring (30). <IMAGE>

Title: Electronic device for determining the average fuel consumption of a vehicle
Inventor: SCHMITT GUENTER
IPC: G01F9/00
Filed: 1981-03-13
Abstract: In an electronic device for determining the average fuel consumption of a vehicle by integration of the fuel flow rate over constant displacement intervals of the distance covered by the vehicle with a displacement pulse generator which emits a displacement pulse for each displacement increment covered, and having a throughflow pulse generator which generates a volume pulse for each volume element which is flowed through, for the purpose of integration of the fuel flow rate over continuously formed displacement intervals whose upper limit is equal to the respective distance covered and whose lower limit extends back into the past by a predetermined amount, a shift register (9) is provided with a plurality of recording stages into whose first recording stage (10) a first binary number (L) can be fed by a loading circuit (13) at each displacement pulse when in each case a volume pulse occurs before this displacement pulse, or a second binary number (O) can be fed when no volume pulse occurs before the displacement pulse. The displacement pulses are used as shift pulses for shifting the fed-in binary numbers through the shift register. An evaluation circuit arrangement (19,20) which converts the contents of the recording stages into the value of the average fuel consumption is connected in each case to one output of the individual recording stages (10,11). <IMAGE>

Title: Lock for pivotable backrests of the rear seats of motor vehicles
Inventor: SCHROM RALF-H
IPC: B60N2/22
Filed: 1981-03-16
Abstract: A lock for pivotable backrests (10, 20, 21) of the rear seats of motor vehicles consists of lock elements (31) which are arranged on both sides of the backrest on the inner wall (30) of the body of the vehicle and of manually actuable bolt elements (15, 17, 26) which are permanently connected to the backrest (10, 20, 21), protrude laterally beyond the latter and interact with the lock elements (31). A linkage (15, 15a), which is mounted inside the backrest (10, 20, 21) or on the rear wall thereof in a horizontal or essentially horizontally arranged fashion and which engages on both sides in each case in a slotted guide (33) of the locking element housing (32) and has on its two ends in each case one actuation element (17), serves as the bolt elements, which actuation element (17) interacts during the rotation of the linkage (15, 15a) about its longitudinal axis with a catch element (34) inside the locking element housing (32). The actuation handle (18, 18a) for the linkage (15, 15a) is arranged in the longitudinal centre (200) of the backrest. As a result, central locking for backrests of the rear seats of motor vehicles is advantageously provided which is convenient to operate and can be used equally well for undivided and for divided backrests. This constitutes a decisive cost-reducing step because with locks of essentially the same design two different equipment variants on the vehicle (divided or undivided backrest of the rear seats) can be provided for. A further substantial advantage of the lock according to the invention consists in the fact that in the event of impact accidents undesired automatic release of the said lock cannot occur. <IMAGE>

Abstract: The invention relates to a device and a method for increasing the service life of kiln wall linings of rotary kilns in the cement industry and a rotary kiln equipped with such a device. The main feature of the device according to the invention is that it has indicating members fastened on the kiln shell and on the running ring, and has sensors arranged along the path of movement of the same. The sensors are connected to an electronic evaluation unit, which includes a power supply section, a pulse generator, a memory and an evaluation unit. The central unit is connected to the output unit or to the indicator. The main feature of the rotary kiln according to the invention is that the kiln is provided with indicating members fastened on the kiln shell and sensors arranged along the paths of movement of the same. In the case of the method according to the invention, the lag of the running ring during one revolution of the kiln with respect to the travel of the kiln shell can be determined by means of the indicating members arranged on the shell of the rotary kiln and on the running ring and by means of the sensors lying along the paths of movement. Furthermore, from time to time the constant ratio s/n of gap to lag is determined. The size of the gap can be continuously determined from this ratio; it is kept within a range between 1.5 and 20 mm, advantageously between 0.5 and 2.0 parts per thousand of the outside diameter of the rotary kiln by intervening in the kiln operation. The operation of the rotary kiln is preferably controlled by altering the firing, the raw material charge or the shell cooling.
