Patent DE-3110829-A1 (DE)
Title: Process for purifying phosphoric acid gypsum
Inventor: HUTTER JOSEF DR
IPC: C01F11/46
Filed: 1981-03-19
Abstract: Purification of phosphoric acid gypsum within the context of a process, according to which the gypsum is first filtered off from the phosphoric acid, is washed with water, is then slurried with water and is again filtered off and washed, the filtrate produced during the second filtration being recycled in its entirety into the process, that part, which in order to maintain the water balance, has to be transferred out going to the phosphoric acid filtration stage as washing water, the remainder being used as water for slurrying the phosphoric acid gypsum. Preferably, the filtrate of the second filtration is separated into a contaminated mud filtrate and a clean washing water filtrate, that part which is put onto the phosphoric acid filter as washing water, being entirely drawn, if possible, from the stream of the contaminated mud filtrate.

Patent DE-3115158-A1 (DE)
Title: Diesel engine with a starting aid
Inventor: KUHN PETER PROF DR ING
IPC: F02N19/00
Filed: 1981-04-15
Abstract: It is the aim of the present invention to facilitate the starting of high-speed diesel engines so as to make it possible to dispense with glow plugs or coils. The inventive idea starts from the fact that the intake valve in the abovementioned engines closes so late that, due to the re-expulsion of previously induced air after bottom dead centre, the charging efficiency during starting is only about 0.6 and that it can be increased significantly by advancing the closing of the intake, leading to an increase in the final compression temperature and hence to easier starting. According to the invention, the closure of the intake during starting is advanced by increasing the valve play of the intake valves during starting, this being achieved by the use of hydraulic valve play compensating elements in which the hydraulic compensation of the play is disabled so that a suitably set mechanical play takes full effect. With the aid of the present invention it is under certain circumstances possible to determine the compression ratio in a manner which is optimum for consumption rather than with regard to reliable starting.

Title: Air drier
Inventor: REPPICH ANDREAS DIPL ING
IPC: B65D23/08
Filed: 1981-08-21
Abstract: An air drier having two treatment chambers (31, 32) is proposed, through which the flow can pass alternately and which are, as a result, alternately regenerable. The two treatment chambers (31, 32) are arranged in a single container (1), only a single cartridge (4) being used. Container (1) and cartridge (4) are divided into two along the length by a multi-component transverse wall (16, 20, 21, 30). A compact construction is achieved in this manner, which requires only a small space. At replacement, only a single container (1) and a single cartridge (4) must be demounted or exchanged, that is the maintenance is simplified. The air drier is intended for use in compressed air brake units of motor vehicles. <IMAGE>

Title: Container transport vehicle with a container which can be set down
Inventor: SCHULTE HEINZ
IPC: B60P1/64
Filed: 1981-11-05
Abstract: In a container transport vehicle (1) with a container which can be set down, the container is of two-component construction, the frame (6) being provided so as to be separable from the container constructed for example as a platform (7) for stackable material. The container is thus composed of two functional elements, namely the actual container and the frame which gives the container the rigidity necessary for transport. As a result, a considerably cheaper construction of the actual container is made possible which can be set down frequently for a relatively long time for loading and unloading purposes whilst the more expensive vehicle with the frame (6) can serve a plurality of containers alternately. The containers (platform 7) are constructed with feet (9) so as to be stackable. <IMAGE>

Patent DE-3202681-A1 (DE)
Title: Emergency power supply circuit for a dynamo-supplied load
Inventor: TROUSSAS JOANNIS DIPL ING
IPC: H02J9/06
Filed: 1982-01-28
Abstract: An electric circuit is described for the short-term power supply of a dynamo-supplied load in the event of dynamo failure, according to Patent ... (Application P 3145775.4). On the one hand, the load is connected via a capacitor in the dynamo circuit so that both half cycles of the dynamo current reach the load. However, the load is additionally connected in an emergency circuit, which is blocked by a semiconductor switching element during normal dynamo operation. The semiconductor switching element is controlled by the combination of a large capacitor and a small capacitor which are connected together with their polarities in reverse parallel via a high-resistance resistor, the small capacitor normally being connected by means of its negative terminal to the control electrode of the semiconductor switching element and blocking said switching element. In the event of dynamo failure, the large capacitor discharges via the control electrode of the semiconductor switching element, so that the latter is switched on for the duration of the capacitor discharge and connects the load to the emergency power source. In this case, the capacitor which is located between the dynamo and the load acts as a return-flow block and prevents the return flow of the current from the emergency power source to the dynamo. Once the capacitor has discharged, the voltage at the control electrode of the semiconductor switching element falls below the threshold value of the switching element again and the current from the emergency power source to the load is automatically interrupted.

Title: Device for determining the real or the virtual distance of a light source from a measurement plane
Inventor: MORANDER KARL-ERIK
IPC: G01B11/02
Filed: 1982-06-15
Abstract: In the case of a device for determining the real or virtual distance of a light source from a measurement plane, using an optical imaging system which images a light beam (which emerges from the light source) onto a photo-detector, in order to reduce the relative measurement error, at least one element of the optical imaging system and/or the light source and/or the photo-detector is displaced by a displacement device in such a manner that a change in the incidence position of the light beam (which is imaged on the photo-detector) does not take place (or takes place only to a reduced extent) as a consequence of a change in the real or virtual distance of the light source from the measurement plane. The real or virtual distance and its change are determined by an evaluation circuit which evaluates the displacement value of the displacement device. <IMAGE>
Patent DE-3223196-A1 (DE)
Inventor: SCHUMACHER KARL
IPC: B62D7/02
Filed: 1982-06-22
Abstract: To obtain unequal angles of turn for two-steerable wheels of a vehicle inexpensively, each wheel is turned through a gear. The two gears have a center to center distance corresponding to the track of the steerable wheels and are dimensioned to accommodate therebetween a meshing pinion mounted eccentrically on a swing arm. While driving one or each of the gears by means of a steering drive element in the same direction of rotation, the positive engagement of the two gears through the pinion and the eccentric mounting of the pinion on the swing arm produce a larger angle of turn of the wheel running inside the turn as compared to the angle of turn of the wheel running at the outside of the turn. To also ensure a steady, flutter-free straight run of the steerable wheels the swing arm end remote from the pinion is adjustable by a selected amount. In addition, the pinion is designed as a duo-pinion comprising two superposed partial pinions adjustable under the resilient force of at least one interposed torsion spring to reduce the tooth space of the entire duo-pinion. Due to this provision, always at least one tooth of one of the gears is in play-free engagement with the duo-pinion.
