Title: Antilock brake system, particularly for a multiple axle vehicle
Inventor: SABA MANFRED
IPC: B60T8/34
Filed: 1981-09-30
Abstract: An antilock brake system, particularly for a multiple axle vehicle, is proposed which has at least one sensed and one unsensed axle. The wheels (5, 6) of the unsensed axle are controlled by the regulated brake pressure for the sensed axle by way of a pressure reducing valve (13, 14). The pressure reduction of the pressure reducing valve is initiated by means of a signal from the antilock electronics unit (18) only when controlled braking is in progress. In order to prevent a brief interruption of the pressure reduction a throttle (25) is provided which retards any unwanted venting of the pressure reducing valves (13, 14). <IMAGE>

Title: Rostrum or platform whose height can be adjusted by hand
Inventor: KLEU GERHARD
IPC: F16M11/38
Filed: 1981-12-01
Abstract: In a rostrum or platform whose height can be adjusted by hand, having a platform, which is supported by a rectangular profiled frame, and four Y-cutters, arranged in pairs on two mutually opposite sides of the profiled frame, latching elements are arranged at the one end in each case of the longer limbs of the Y-cutters, which latching elements, at the set height position of the platform, latch into latching holes which are open downwards and are worked in on latching strips of the profiled frame, the latching elements being secured in the latching holes by an additional component. In order to dispense with the component which is used for security and to simplify the height adjustment of the platform, the latching holes are worked in on the upper edge of the latching strips in such a manner that they extend into the latching strips obliquely from the opening, the latching holes having, on the inner end, an expansion which extends parallel to the upper edge of the latching strips, and the latching holes of the one pair of cutters pointing in the opposite direction to the latching holes of the other pair of cutters.

Title: Air purification device for eliminating air-borne and odorous substances
Inventor: SCHMAHL ARNO
IPC: B03C3/155
Filed: 1982-01-19
Abstract: The invention is based on the object of providing an air purification device which operates with a low air velocity and has an intensified purification effect with respect to both odorous and air-borne substances and bacteria. According to the invention, this object is achieved if the air drawn in through a suction grid by means of a fan successively flows through a wire grating, arranged at a distance from the suction grid, and an activated carbon filter in turn arranged at a distance from the latter, the wire grating being connected via a lead to the positive pole and the activated carbon filter being connected via a further lead to the negative pole of a high-voltage generator. The activated carbon filter is preferably divided into superposed lamellae, between which gaps for the air to pass through are located. As a result, the disadvantages of conventional air purification equipment, namely the inadequate elimination of odour and the inadequate retention of air-borne substances, and also the corona discharge which causes an inadmissibly high ozone concentration in the issuing air, are eliminated.

Title: Motor vehicle with a driver's cab and a mounted camper body
Inventor: TOMFORDE JOHANN DIPL ING
IPC: B60P3/32
Filed: 1982-08-19
Abstract: The application relates to a motor vehicle with a driver's cab and a mounted camper body which is wider than the driver's cab and has a projecting part which extends into the region above the roof of the driver's cab, provides sleeping places and terminates approximately with the front edge of the roof of the driver's cab. An aerodynamically favourable design of a motor vehicle of this type is intended to be achieved according to the invention in that the projecting part is designed as the flat shell, the top side of which forms a hinged lifting or pivoting roof, and in that the width of the projecting part, in the region above the windscreen, corresponds to the width of the driver's cab and from there increases rearwards, preferably continuously, until it reaches the width of the camper body.
Patent DE-3232469-A1 (DE)
Title: Rotary kiln drying oven with infinitely adjustable control of speed of rotation
Inventor: HARTMANN HEINZ LEOPOLD DIPL IN
IPC: F26B11/02
Filed: 1982-09-01
Abstract: Infinitely adjustable changes in the speed of rotation of the rotary drum are disadvantageous in the case of running roller/friction wheel drives because, when the speed of rotation is reduced, the torque to be delivered increases on the side of the ascending friction wheel drives, and correspondingly decreases on the side of the descending friction wheel drives. The normally existing ratio of 6:4 of the drive torques on both sides is displaced in this case to about 8:2, which leads to harmful slip and increased wear of the friction wheels. The invention eliminates this disadvantage by means of a running roller/friction wheel drive with two separate controls of speed of rotation for the ascending and the descending friction wheel drives which are controlled in a compensatory manner by freely selectable associated characteristics, corresponding to the changes of speed of rotation of the drum, of the resultant changes in degree of filling, residence time of the material, temperature of the material, exhaust gas temperatures and/or the gas resistance of the drum, with respect to the heating gas flowing through, such that the ascending and descending friction wheel drives transmit about the same torques to the rotary drum at all speeds of rotation of the drum.

Patent DE-3247084-A1 (DE)
Title: Circuit arrangement for converting a binary signal, alternating between two levels, into a pulse code signal
Inventor: GOERNE JAN DIPL ING
IPC: H04L25/49
Filed: 1982-12-20
Abstract: In an arrangement containing two pulse generators (2, 4) for converting a binary signal, alternating between two levels, into a pulse code signal, the pulses of which are synchronised with the sudden changes in level of the binary signal, there is a timing element (7) which, upon the elapse of a maximum time since the last pulse generation, in each case initiates the emission of an intermediate pulse by the pulse generator which was last activated, and at the same time emits a blockade signal for the other pulse generator. If the blockade signal and the sudden change in level of the binary signal coincide, the blockade is neutralised by means of an inhibiting signal, which is derived from the sudden change in level of the binary signal, and this eliminates the possibility of any delay of the rising edge (phase jitter) of the pulse response to the sudden change in level of the binary signal. <IMAGE>

Title: Heat and power machine operated by external heat supply
Inventor: EDER FRANZ X PROF DR ING
IPC: F02G1/044
Filed: 1983-01-26
Abstract: The heat and power machine comprises two working cylinders filled with high pressure gas (for example helium) each with a displacer designed as a stepped piston, which with a phase displacement of approximately 90 DEG  are periodically moved to and fro and the narrower sections of which in coaxial auxiliary cylinders form additional, likewise periodically varying gas chambers. The working chambers in the cylinders separated by the displacement pistons are connected by way of heat recovery devices and heat exchangers by way of which heat energy is fed to the machine at high and very low temperature and the available heat output drawn off at moderately high temperature, that is effective water temperature. If the connecting lines between the working chambers with moderately high temperature and the working chambers in the auxiliary cylinders are connected to one another by way of a throttle valve, when the valve is opened the machine functions as a heat pump or cooling unit, and when the valve is fully or partially closed, in addition to the heat output a significant mechanical power is given off which can be used, for example, to generate current.
