Patent DE-3826516-A1 (DE)
Title: Device for applying a paste onto grid material in the form of a strip
Inventor: OSTRANDER PAUL RAYMOND
IPC: H01M4/20
Filed: 1988-08-04
Abstract: In the case of a control system or regulating system for a paste feed shaft, the density and the thickness of a lead-oxide paste, which is applied onto a strip of a battery grid material via a feed shaft, are controlled or regulated independently of one another as a function of in-line measurements of the density and thickness downstream of the paste feed shaft. The paste density is controlled or regulated independently on two sides of the strip by means of feed shaft stirring devices which rotate independently, can be driven separately and are at a distance in the transverse direction, as a function of the density measurements on both sides of the strip. The plate thickness is controlled or regulated independently on two sides of the strip by setting the height of the ends of a monitoring roller as a function of the thickness measurement carried out downstream and by matching to the height of the feedshaft as an entity.

Title: Service trolley
Inventor: SCHUMM WILHELM
IPC: A47B31/06
Filed: 1988-09-27
Abstract: A service trolley for passenger-carrying vehicles, in particular coaches, has drawers which are guided in guides in a manner running obliquely upwards to the horizontal and to the direction of movement, so that the drawers endeavour to remain in the drawn-in state under the effect of gravity. A device for detachably latching the trolley to the vehicle in its centre aisle and for centrally locking the drawers comprises an actuating element which, on the one hand, causes the latching of the trolley and simultaneously unlocks the drawers, and, on the other hand, when the trolley is unlatched automatically draws in the drawer still drawn out, via a lever which is coupled to the actuating member and can be brought into contact with a guide arm articulated on the drawer.

Title: Heat increaser
IPC: F24H4/02
Filed: 1988-12-24
Abstract: Heat increaser for space heating, consisting of a burner, an evaporator which is heated by the burner and in which a heat transfer medium, introduced in the liquid state, evaporates under steam and then drives an expansion engine, the power of which is transmitted to the compressor of a heat pump impinged by outside air. A liquid or gaseous heat transfer medium for heating up the space air is first conveyed through the condenser of the heat pump, then through the condenser downstream of the expansion engine and then preferably through a heat exchanger which cools down the combustion gases below their dewpoint. The expansion engine and compressor form a free-piston unit, the pistons being set in rotation about the geometrical axis to build up a carrying gas cushion, so that the mechanical unit runs in contactless fashion and thus free from wear.

Patent DE-3911043-A1 (DE)
Inventor: KOERBER GUENTHER DIPL ING
IPC: E02D19/18
Filed: 1989-04-05
Abstract: The device consists of guide rails (13, 14) inserted in pairs into a suspension-filled slot (10) in the earth. The ends of a sealing membrane (12) are guided on the guide rails (13, 14) during the lowering. The two rails (13, 14) are mounted on the guiding wall (40) of the slot (10) in the earth by self-aligning bearings (38, 39) so that they can be aligned exactly vertically and parallel to one another on account of their dead weight. In addition, both guide rails (13, 14) are provided with sliding rails (27, 28). The membrane sheet (12a, 12b) to be lowered is fastened to a weighted horizontal spacer (31) which is guided laterally in the sliding rails (27, 28) via carriages (29, 30). In this way, canting of the membrane sheet (12a, 12b) in the guide rails (13, 14) is avoided during lowering, the spacer (31) ensuring the parallelism and alignment of the guide rails (13, 14). <IMAGE>

Title: Processing small size fruits by defrosting in container - also used for thermal sterilisation and cooling to packaging temp.
Inventor: WULF GUENTER DIPL ING
IPC: A23L3/16
Filed: 1989-09-15
Abstract: Fruit is processed for use in foodstuffs, e.g. strawberries to form a yoghurt additive, in an enclosed container (1) when an initially frozen charge is defrosted by heating and with any necessary additives is heated to sterilisation temp., followed by cooling to packaging temp. to accelerate defrosting liq.  collecting at the container base (5) is extracted, and via a feed-line (19,16) including pumps, valves and a heat exchanger (17) is returned to the container head at appropriate temp., pref. the fruit sterilisation temp.

Patent DE-3935994-A1 (DE)
Inventor: LENHARDT KARL
IPC: E06B3/673
Filed: 1989-10-28
Abstract: The description relates to a process and device for combining two sheets of glass (1, 2) to form an insulating glass pane by injecting a bead (9) of substances in paste form into the space between the two glass sheets. For this purpose a nozzle (3) is used which is taken around the pair of sheets by an automatic handling device which mutually moves the nozzle (3) and the two glass sheets. During this process the nozzle penetrates into the intermediate space in such a way that its aperture (8) faces away from the direction of movement. When, at the end of the injection process, the nozzle (3) approaches the beginning (12) of the bead, it is stopped and directed, especially by being pivoted by a quarter turn about a spindle (14) on the outer edge of the bead (9), in such a way that its aperture (8) points into the intermediate space. The nozzle (3) is then again moved along the edge of the glass sheets to close the remaining gap (13).

Abstract: A line device, preferably a line terminating device (LE) of a communication system which contains transmitting and receiving circuits (S1, S2, SN; E1) to which transmitting lines (SL1, SL2, SLN) and receiving lines (EL1) are connected, contains at least one receiving circuit (E1) comprising a circuit arrangement (KS) for compensating for crosstalk. A single circuit arrangement (KS) compensates for the crosstalk from several transmitting lines (S1, S2, SN) to one receiving line (EL1). For the compensation, a reference signal (R(1)1, R(1)2, R(1)N) of the transmitting signal is branched off from each transmitting circuit (S1, S2, SN) and a compensation signal (K1, K2, KN) is simulated by an adaptive filter (F1, F2, FN). The individual compensation signals are additively mixed with the receiving signal via subtraction inputs of a subtraction circuit (S). A part of the output signal of the subtraction signal (S) is supplied to the control signal inputs (RS1, RS2, RSN) of the adaptive filters (F1, F2, FN), the other part is processed further to become the receiving signal (DA1).
