Title: Automatic control for vehicle parking brake - has microswitches as sensors to determine occupation of driving seat, holding brakes off
Inventor: YATES LYNTON
IPC: B60T7/12
Filed: 1980-06-02
Abstract: The application of the automatic brake control is to specialised vehicles employed in factories, for example fork lift trucks, side loaders, and similar appliances. The object is to prevent release of the vehicle brakes if there is no driver on board and in the driving seat. Occupation of the driving seat is monitored by electrical sensors, typically microswitches on each side of the seat cushion. This arrangement of electric sensors, requires only small movements of the seat. It thus simplifies the mechanical construction of both seat and brake interlock. The electric circuit works in conjunction with a solenoid valve operating on the hydraulic brake circuit to hold the brakes off when the seat is occupied. Release of the hand brake then only permits vehicle movement when the seat is in use.

Title: Rotating body bearing esp. for balancing machines - has vertical and inclined stiffening members giving omnidirectional support
Inventor: HIMMLER GUENTHER ING GRAD
IPC: F16C27/00
Filed: 1980-06-20
Abstract: A bearing for a rotating body, esp. in a balancing machine, provides rigid support w.r.t. the machine bed for the rotating body in the radial plane for all directions. This is achieved using two support springs (8, 7), whilst retaining sufficient space for an additional processing device, esp. one which can be attached to the central axis of the body in the horizontal direction. The first support spring (8) forms part of the vertical stiffening component. The second support spring (7) forms the resultant of the vertical residual stiffness component and the total horizontal stiffness component. The first support (8) is vertical and the second (7) at an angle (2) to the horizontal. One or both are offset so that their axes (12, 13) intersect off the bearing central axis.

Patent DE-3027220-A1 (DE)
Title: Desulphurisation of coke oven gas - by ammonia scrubbing and stripping with improved pH control
Inventor: ANTHES JOHN A
IPC: C10K1/12
Filed: 1980-07-18
Abstract: In the desulphurisation of coke oven gas, the washed gas is scrubbed with aq NH4OH soln., and the used soln. then stripped of acid gases (including H2S) in a stripper. Improvement is the addn. to the used NH4OH soln. in the stripper of some prim. water-washings of the coke-oven vas, which contain NH4 salts of strong acids e.g. NH4C1, and are conventionally sent to the scrubber instead. These washings raise the PH in the stripper and so aid the thermal breakdown of NH4 salts of weak acids, including NH4HS. The H2S concn. in the coke oven gas after scrubbing is less than from conventional NH3-absorption processes, and is environmentally acceptable.
Patent DE-3029034-A1 (DE)
Title: Narrow band radio receiver - has A=D converter and shift register for detecting identifying signal and extending battery life
Inventor: ESPRESTER RALF DIPL ING
IPC: H04B1/16
Filed: 1980-07-31
Abstract: The narrow band signal is picked up by the antenna (1) and fed to the narrow band input section (2). The input section (2), which is continually on, processes the signal in an analogue fashion and demodulates it, passing the output signal to a sampling circuit (3), where it is analysed at regular time intervals. The values are then passed, via an analogue/digital converter to a shift register (5) where they are then stored. The sampling and timing of the shift register (5) are controlled by a common timing impulse generator (7). The pulse frequency of the generator (7) is divided in a counter (8) in the ratio of 5 to 1 and the reduced frequency entered into the analysing unit (6) at the start of the process cycle. The latter (6) is also connected to the shift register (5) and tests its entire contents for the presence of an identifying signal. If this is established, a corresponding signal is produced to start a pre-programmed command. In this way, input power to the receiver is reduced and battery life extended.

Patent DE-3044665-A1 (DE)
Title: Suction filter press has floor pivoting centrally - between horizontal operating position and tilted position for cake discharge
Inventor: HORN MARTIN
IPC: B01D29/01
Filed: 1980-11-27
Abstract: A suction filter for sepg. slurries into compact sludge and clear filtrate has a fixed dome mounted on a base frame contg. a central pivot. About this pivot tilts the filter floor which in its horizontal position forms a sealed pressure vessel and carries the cloth for filtering slurry fed into the top of the dome to a controlled level. Compressed air fed into the dome above the slurry forces filtrate out through a pipe descending below the floor. After filtration, the air supply is interrupted and the floor is mechanically tilted into a generally upright position. A pulsating air supply is now delivered below the cloth, causing the filter cake to detach and fall. The floor can then be rotated for a fresh cycle. The press is compact, with no pivoting parts projecting from the contour, and is easily operated. The basic unit is small and can be combined in a battery with others.

Title: Digital, clocked comparator circuit
Inventor: LEHMANN ERWIN ING GRAD
IPC: H03K19/21
Filed: 1981-01-28
Abstract: The invention shown in Figure 3 relates to a digital, clocked comparator circuit for high clock frequencies with the basic function of an "exclusive"-OR circuit for two input variables. Unlike known comparator circuits with a relatively slow-switching "exclusive"-OR circuit and an equally slow-switching D-type flip-flop, the subject matter of the invention comprises only fast-switching NAND circuits and a comparatively fast-switching JK-type flip-flop. The input variables (A and B (or A and B)) produced in flip-flops (1 and 2) disposed upstream are combined in two NAND circuits (5 and 6) and the two inputs (J and K) of a JK-type flip-flop (9) are activated with the resulting signals. Two further NAND circuits (7 and 8) which are also activated with the input variables and, in addition, with the signals obtained at the outputs (Q or Q) of the JK-type flip-flop (9) prevent the setting or resetting of the JK-type flip-flop (9) if the latter is already in the correct logical state before a clock pulse is received from the clock (T) which clocks the output signal (X). <IMAGE>
Patent DE-3108908-A1 (DE)
Title: Hydraulic power amplifier
Inventor: BELART JUAN
IPC: B60T13/12
Filed: 1981-03-09
Abstract: The invention starts from a hydraulic power amplifier in which amplifier piston and brake valve are arranged parallel to one another and in which a lever acts on a pedal-operated piston rod, which lever is pivotably mounted on the amplifier piston and opens the brake valve during brake actuation. In the known arrangement, it has to be regarded as a disadvantage that the amplifier piston moves away from the piston rod during brake actuation, so that considerable idle travel of the pedal occurs if there is a failure of auxiliary power in the brake-actuating position. In contrast, the invention (Fig. 1) proposes that a first lever (14) linked to the piston rod (8) be pivotably mounted in the housing (1) and that a second lever (17) be arranged essentially parallel to the first lever (14), one end of which second lever (17) lies in the line of action between piston rod (8) and amplifier piston (4) and the other end (23) of which acts on the brake valve (20, 25). Furthermore, the levers (14, 17) are rotatably connected to one another. By a design of this type, the idle travel of the pedal is reduced to a minimum if there is a failure of auxiliary power in the brake-actuating position. <IMAGE>

Title: Method and arrangement for storing or transmitting and for recovering image signals
Inventor: LUX PETER DR RER NAT
IPC: H04N19/124
Filed: 1981-06-23
Abstract: During the transformation coding of images, an increase in the range of values of the coefficients generated during this process is produced by the arithmetic operation on the image signals. To reduce or completely to eliminate this increase, the possible range of values of the coefficients is determined as a function of the preceding coefficients and the quantising characteristic is set accordingly. For this purpose, it is only necessary to store the maximum value of the preceding coefficients or the minimum difference between the preceding coefficients and half the maximum value range and, as a function of this, to switch over the characteristics memory which controls the quantiser. During the decoding, the characteristic of the decoder is correspondingly switched over as a function of the previously decoded coefficients. <IMAGE>
