Title: Contactless measurement of external ignition engine revolution rate - using coils detecting ignition coil magnetic field outside car
Inventor: NAKANO KAZUHARU
IPC: F02D45/00
Filed: 1980-08-18
Abstract: A contactless revolution rate measurement arrangement for vehicle external ignition combustion engines enables simple high precision measurements to be made at a point remote from the vehicle body. This enables final assembly checks to be made quickly as required in a factory. An electrical signal is induced in a measurement coil (3,4) by the magnetic field set up by the engine ignition coil. The signal is amplified in a noise-free amplifier (6,7) and fed to a low pass filter (8,9) passing an output signal frequency component proportional exclusively to the engine revolution rate. The low pass filter output is processed into a revolution rate signal by a correlating revolution rate counter (12). Two measurement coils (3,4) may be used, one either side of the car. In this case the two filter (8,9) outputs are added.

Title: Controllable positioning system for recording and reproducing apparatuses, in particular for video apparatuses with longitudinal track recording
Inventor: RICHTER MANFRED
IPC: G11B5/584
Filed: 1981-02-13
Abstract: A controllable positioning system for recording and reproducing apparatuses, in particular for video apparatuses with longitudinal track recording, is described. In the case of such apparatuses, the difficulty and complexity involved in video head switching and tracking control with extreme precision and greatest possible speed present a great problem. To solve this problem, according to the invention as shown in Fig. 1, a control system responsible for accuracy and a pulse generating stage for accelerating and braking pulse trains, responsible for the high switching speed, are provided, in which arrangement a switching device is used in the "normal mode" to close the control loop to form an output stage connected to a balancing stage and having a transformer connected to it, and to switch over to the pulse generating stage at the beginning of a movement cycle of the video head and not switch back to the control loop until the accelerating and braking operation for a head movement stage has been completed. <IMAGE>

Title: Process and apparatus for the recovery of heat in laundries
Inventor: ENGELBRECHT HANS
IPC: D06F39/00
Filed: 1981-03-25
Abstract: The invention relates to a process for recovering the waste heat occurring in laundries, all the waste-heat sources, such as washing machines, laundry driers, laundry mangles and smoothing presses, being included. The waste air from the laundry driers, hot mangles and smoothing presses is fed jointly to a combination heat exchanger (1), in which the sensible heat and the condensation heat of the steam carried along are extracted from the waste air and transferred to the fresh water streaming in counterflow. The water preheated in this way is heated further in counterflow in a heat exchanger (37) by the hot waste lye of the washing machines and is collected in a reservoir (18). The feeding of hot water to the washing machines achieves not only a saving of heating energy, but also, as a result of the reduction in the heating time, an increase in the throughput capacity. <IMAGE>
Patent DE-3113726-A1 (DE)
Title: Agricultural ground-working machine
Inventor: BRAUN JOSEF
IPC: A01D34/74
Filed: 1981-04-04
Abstract: In an agricultural ground-working machine (1), with at least one cutter (11) drivable about a vertically directed axis, the latter is supported on the ground (A) by means of a sliding plate (17) arranged concentrically and under the cutter (11) and, together with the sliding plate (17), is held in a supporting frame so as to be vertically adjustable relative to the associated drive-transmission member (3). For this purpose, the shaft (12) carrying the cutter (11) is held fixedly in terms of rotation and axially displaceably in a sleeve (5) connected to the drive-transmission member (3) and is supported in an axial direction on this sleeve (5). Damage to the cutter bezels by striking against obstacles is virtually prevented in this way. In particular, as soon as the sliding plate (17) arranged under the cutter (11) slides on an unevenness of the ground or on an obstacle, the sliding plate (17) and the cutter (11) connected firmly to the latter are raised according to the height of the elevation, so that the cutter bezels do not come into contact with the obstacle. However, the drive connection is not changed during this, and also no interruptions in force have to be allowed for. Moreover, no jolt-like loads occur, so that the components involved in force transmission can have small dimensions. <IMAGE>

Patent DE-3114793-A1 (DE)
Title: Brake magnet for electricity meters
Inventor: STEINGROEVER ERICH DR ING
IPC: H01F7/02
Filed: 1981-04-11
Abstract: The invention deals with brake magnets for electricity meters having an essentially U-shaped carrier body (1) at the legs of which one or more permanent magnet bodies (2, 3), which are magnetised with one or more tracks, of highly coercive permanent-magnet alloy are mounted, forming a working air gap (4) through which the magnetic fluxes of the permanent-magnet bodies pass, for a brake disc. At least one of the permanent-magnet bodies (2, 3) is provided on one side with a temperature compensation member (5) of hard ferrite which can consist of barium ferrite or barium strontium ferrite - either in solid form or in a compound with plastic. This very greatly reduces the influence of temperature fluctuations on the braking torque of the brake magnet, and the braking power can be finally calibrated by an adjustable shunt body (6) which is arranged on one side of one of the permanent-magnet bodies (2, 3) in parallel with the yoke (1a) of the U-shaped carrier body (1). <IMAGE>
Patent DE-3117114-A1 (DE)
Title: Filtering separator
Inventor: SCHMIDT WOLFGANG
IPC: B01D46/42
Filed: 1981-04-30
Abstract: Cartridge-shaped filter elements in filtering separators must be exchanged despite periodic cleaning by compressed air pulse flushing: the old cartridges must be detached and removed and the new ones introduced and attached, a procedure which is laborious, despite bayonet closures, particularly when the housing has great depth. According to the invention, a venturi nozzle (23), which is furnished at its free end with a sprung tensioning clip (26), is attached to each cartridge (20) inserted into the hole of the tube sheet (10) assigned thereto. Above each row of cartridges is provided a cross-beam (18) having stops (30) arranged above each cartridge interacting with the tensioning clips (26). Engagement of the tensioning clips (26) into the notches (30) fixes each cartridge-venturi nozzle combination (20/23). In a further development, the cross-beam (18) is displaceable in the longitudinal direction, the tensioning clips (26) being additionally tightened or relaxed. Finally, the cross-beam (18) is designed as a compressed air distributor of the pulsed backflushing having efflux nozzles (19) which lie axially to the cartridges (20) in the tensioned state. <IMAGE>

Title: Positively guided rail line, in particular for use in underground mining operations
Inventor: LACHNER HANS DIPL ING
IPC: E01B25/24
Filed: 1981-06-11
Abstract: The rail line according to the invention is constructed in the manner of an overhead twin-rail chain conveyor and has a chain (1, 6) which slides in a positive guide (7). The chain (1, 6) is articulated in three dimensions, can be collapsed to a limited degree and is free of self-locking in the collapsed state in the positive guide (7) and is driven by any desired number of intermediate drives by means of chain wheels which engage in them. As a result of the specified properties of the chain (1, 6) it is possible to insert the suspension chain which is formed behind each intermediate drive into the subsequent positive guide (7) so that the chain does not have to be prestressed and can be as long as desired. By arranging positively synchronised wheels in front of and after sharp bends it is also possible with the rail line according to the invention to reduce the friction between chain (1, 6) and positive guide (7) in bends considerably. <IMAGE>

Title: Laying plough
IPC: E02F5/10
Filed: 1981-10-01
Abstract: The invention relates to a plough for laying elongate elements in the soil, with a longitudinally extending shaft which has at the front a pulling ring and at the rear a downwardly extending ploughshare with a cutter inclined obliquely relative to the pulling direction, with a short guide fin extending parallel to the ploughshare, and with a sliding shoe arranged at the front end of the shaft. The invention is characterised in that there is arranged at the lower end of the ploughshare an elongate guide body which is widened relative to the thickness of the ploughshare and which is inclined obliquely downwards in the pulling direction, and in that at least the shaft together with the ploughshare and with the guide body is designed as a light-weight construction made of high-strength steel. In comparison with the known laying ploughs, a drastically reduced overall weight and a considerably reduced pulling resistance during work are obtained, the advantage of this being that the handling of the plough and its transport from and to the work point become fundamentally easier, and that the pulling force of conventional vehicles, that is to say no specially designed traction vehicles, is sufficient for pulling.
