Title: Process and device for recording a circular track on a data storage disc
Inventor: SPENGLER WERNER DR
IPC: G11B21/10
Filed: 1986-09-24
Abstract: An auxiliary track is recorded on the data storage disc (1) with the aid of an additional read/write head (4'). When scanning the auxiliary track, position signals (83) are generated in dependence on the track position in the circumferential direction of the data storage disc and are buffer-stored. This scanning operation is repeated several times and average values of the position signals are thereby obtained for the individual track positions, which are stored. For recording circular tracks with the aid of the write head (4) on the data storage disc (1), at the same the auxiliary track is scanned. The corresponding current position signals and the associated stored average values are used to form difference signals, which serve as track-deviation signals for fine correction of the momentary radial position of the write head (4). <IMAGE>

Patent DE-3731408-A1 (DE)
Title: Brake system with slip control
Inventor: REINARTZ HANS-DIETER
IPC: B60T8/44
Filed: 1987-09-18
Abstract: A brake system with slip control is proposed, in which the brake pressure in the wheel brakes is influenced by discharge of pressure medium into a reservoir (valve 14) or by topping up of brake pressure medium by means of a hydraulic pump (16, 17) (valve 13). Should the pump (16 and 17) fail, the discharged pressure medium must be re-delivered from the brake master cylinder (1), thereby exhausting its volume of pressure medium. Flow sensors (27, 37) are therefore provided either in the pressure line (19, 20) or in the suction line (18) by means of which it can be detected whether the pumps (16, 17) are delivering. If it is detected that delivery is absent, the brake slip control is interrupted, that is the outlet valves remain in their closed positions. <IMAGE>

Patent DE-3743569-A1 (DE)
Inventor: SCHMIDT ALFRED
IPC: F01L13/06
Filed: 1987-12-22
Abstract: There is a slide valve for a fluid, in which a piston slide (3) in a housing chamber (2) of a valve housing (1) can move axially in a reciprocating manner, in which, in the valve housing (1), a housing channel (7) connected to a first connection (8) is provided with a through-flow opening facing the piston slide (3) and in which, in the piston slide (3) a slide channel (14), connected to a second connection (11), is provided with a through-flow opening facing the valve housing (1). In this arrangement, it is desired that the slide valve, in which flow stoppages resulting from fluid impurities do not occur, is designed such that the flow control can be carried out in a more finely sensing manner. This is achieved in that the outlet-side through-flow opening extends over a cut-out (16) originating from the associated channel (14), the cross-section of which cut-out (16) tapers in the axial direction towards the inlet-side through-flow opening when the piston slide (3) is in the blocked position. For flow control in the slide valve, not only is the overlapping region of the two through-flow openings moved but moving the piston slide also changes the cross-section available for the fluid to flow out of after passing through the overlapping region.

Patent DE-3807890-A1 (DE)
Title: Process and apparatuses for generating smoke for smoking
Inventor: SCHMIDT EDWIN P
IPC: A23B4/056
Filed: 1988-03-10
Abstract: In conventionally known smoke generators, the proportion of the pollutants volatile in the smoke resulting from exothermic reactions at the pyrolysis temperature can drastically increase by supplying fresh air to the site of pyrolysis. There is also the hazard of the smoke gas detonating. Cleaning the interior raises difficulties. Arranging electrical heating elements and other devices, including rotating devices, in the hot carbonisation space is also a disadvantage. These disadvantages are to be eliminated according to the invention by the inductive heating of the loose, removable pyrolysis plate on which smoke for smoking is continuously produced low in pollutants under temperature control and without supply of fresh air, with metered feed of sawdust and unimpeded discharge of the pyrolysis residues. Covering the sources of ignition by metal wire mesh prevents the detonation of the smoke gas. Problem-free, economical generation of low-pollutant smoke for smoking results therefrom for preserving and aromatising foods such as meat products, sausage products and fish products.
