Patent DE-3120834-A1 (DE)
Title: Pneumatically working drilling hammer
Inventor: BEISCH HANSPETER ING GRAD
IPC: B25D16/00
Filed: 1981-05-26
Abstract: A pneumatically working drilling hammer, with a drive motor arranged perpendicularly to the tool for producing an axial and rotary movement of the tool in such a way that an eccentric for actuating a working piston guided in a cylinder liner and a bevel gear sitting on the cylinder liner are driven via a pinion attached to the motor shaft, is to be improved to the effect that the ratio of output to weight is more favourable and the space requirement and design effort are reduced to a minimum. This is done by virtue of the fact that the motor-shaft pinion transmits its rotary movement directly and simultaneously to an eccentric shaft provided with a corresponding gear and having a hollow space and to a bevel-gear shaft of hollow design likewise containing a meshing gear for the pinion, and that the eccentric shaft is at the same time designed as a crank pin for the drive of the working piston and the bevel-gear shaft is at the same time designed as a bevel gear for the drive of a cylinder liner imparting the rotary movement to the tool, and that the bevel-gear shaft as well as the eccentric shaft are each rotatably mounted on a pivot pin projecting into their hollow spaces.

Patent DE-3134551-A1 (DE)
Title: Stepping switching mechanism for the precise setting of a pick-up head, in particular of a magnetic transformer head, transversely over a recording carrier
Inventor: PAPE MANFRED ING GRAD
IPC: G11B5/55
Filed: 1981-09-01
Abstract: In the case of a stepping switching mechanism for the vertical adjustment of a scanning head fastened on a control feeler, for example of a magnetic transformer head, to one of several predetermined positions of a recording carrier, in particular of a video tape, low weight and volume are to be achieved along with high reproducing accuracy by a few sturdy mechanical parts. For this purpose, according to Fig. 2, in the invention a worm segment (6), driven by an electric motor (4), is in engagement with a worm wheel (11) only over about 270 DEG  angle of rotation of each revolution. The said worm wheel (11) has a number of teeth corresponding to the number of tracks of the recording carrier and is connected to a pitch wheel (12) with a coaxial, constant pitch face (13), on which a control feeler (14) with the magnetic head (21) rests under spring pressure. At the circumference of the pitch wheel (12), detents (16) corresponding to the number and spacing of the tracks of the recording carrier are provided. During the engageless phase of rotation of the worm segment (6), a ball lock (18, 19) engages in the said detents and securely holds the pitch wheel (12), and consequently the magnetic head (21) guided by the control feeler (14), on a particular track of the recording carrier. By connecting the worm wheel (11) to an optoelectronic control means, in this case a track search is also possible. <IMAGE>

The connecting tabs (21) of the metal foils (2) are connected together in pairs and project out of a parallelepiped pressed sheathing (3) which protects the capacitor against external influences. <IMAGE>
Patent DE-3138098-A1 (DE)
Title: Heating system for a motor vehicle
Inventor: HANDA NORITOSHI
IPC: B60H1/08
Filed: 1981-09-24
Abstract: An auxiliary heater (20) uses a U-shaped ribbed heating pipe (42) in a housing which is either fastened to or integral with a cylinder block (26). Coolant is fed into the housing (30) from the cooling jacket (26) or from a heat exchanger (38) via an inlet (32) by means of a coolant pump (36) for coolant after a vehicle cabin has heated up. The heated coolant is discharged via an outlet (34) of the housing and subsequently conducted to the heat exchanger (38). The direct connection between the auxiliary heater and the coolant (26) reduces the expenditure in terms of lines and permits the weaker pump (36) to be used. The arrangement also reduces the surface over which heat can be lost and at the same time promotes the heating up of the engine. <IMAGE>
Patent DE-3138561-A1 (DE)
Title: Protection device for steam turbine systems, whose functional safety can be tested
Inventor: CARLHEIM KURT-WERNER DIPL ING
IPC: F01D21/18
Filed: 1981-09-28
Abstract: A protection device for steam turbine systems, whose functional safety can be tested, having a plurality of monitors (20, 23, 28) which monitor operating parameters that are critical to operating safety and, if limit values which can be predetermined are exceeded, apply a rapid-closure signal to associated trip devices (16, 17, 18, 25, 26). When a rapid-closure signal occurs, the trip devices (16, 17, 18, 25, 26) generate a hydraulic rapid-closure trip signal, which drives a main trip device (8). When a rapid-closure trip signal occurs, the main trip device (8) relieves the pressure on the servo piston (3) of a steam shut-off valve (1) and hence causes a rapid closure. A bypass changeover switch (9), which is arranged in a bypass line (11) to the main trip device (8), enables the trip devices (16, 17, 18, 25, 26) and, if applicable, the monitors (20, 23, 28) as well, to be tested individually for their serviceability, and in consequence a rapid closure of the steam shut-off valve (1) is prevented. The capability for rapid closure of the steam shut-off valve (1) in the case of danger is maintained even during testing by means of a further main trip device (10), which is driven by further trip devices (31, 32). <IMAGE>

Title: Regulation of the flushing operation in WC flushing cisterns (by means of a permanently flexible sponge)
Inventor: STOERZLE HORST
IPC: E03D1/14
Filed: 1981-11-13
Abstract: Using this method, it is possible to alter the functioning of surface-mounted WC flushing cisterns, which use their entire water contents at each flushing, in a very simple way, such that both flushing with the entire quantity of water and flushing with part-quantities, which can be infinitely adapted to the particular flushing need, is possible. This water-saving alteration is brought about by a permanently flexible plastic sponge piece adapted to the particular flushing-cistern model in terms of size. This plastic sponge piece is fixed in the flushing-cistern lid (e.g. by adhesive bonding), in such a way that when the lid is mounted it bears, by way of the centre of its underside, with moderate pressure on the outlet valve or another constructional part closely associated therewith and moved upwards on actuation of the triggering handle (see drawing). Fastened in this way, the sponge piece is compressed against the lid by the outlet valve or constructional part (e.g. pusher lever) moved upwards on triggering of the flushing operation. With the increased elastic restoring force produced thereby, the sponge piece closes the outlet valve automatically, against the pressure of the water flowing out, as soon as the triggering handle is released. <IMAGE>

Title: Spacer and extension element for use in prefabricated building elements
Inventor: JUKES CHRISTOPHER E
IPC: E04B2/86
Filed: 1982-03-23
Abstract: A prefabricated spacer and extension member which is usable as a permanent element and is in the form of a locking plate is usable with a likewise "permanent" wall construction in order to produce a concrete wall having a spur or buttress. One plate or a plurality of plates can connect two or more connecting members of the wall structure in an extended linear dimension which is greater than the normal width of a wall block or a wall building unit, the width of which usually corresponds to the width dimension of a connecting member. The spacer and locking plate usable as a permanent element has preformed slots which co-operate with projections on the connecting members, in such a way that after a deformation of the projections the connecting members are locked to one another and a rigid member of increased strength is formed. If such a structure is filled with concrete, suitable spurs or buttresses are thereby produced.

Patent DE-3229161-A1 (DE)
Title: Process and device for winding textile webs onto lap rods
Inventor: TOEGEL ALFRED DIPL ING
IPC: B65H18/20
Filed: 1982-08-04
Abstract: The invention relates to a process and a device for winding textile webs onto lap rods, especially webs of nonwoven or other light and superficially rough materials. Webs of nonwoven, wadding or other material sensitive to tensile force cannot be wound by conventional methods and devices, especially when the material web has a large thickness. To solve this problem, it is proposed by means of the invention that the start of the material web (11) be laid in an intially open elongate loop (13) around the lap rod (4) and introduced into a winding space (12) open on one side. The winding space (12) is formed by three rollers (8, 9 and 10) which are driven in the same direction at a speed increasing from roller to roller in the conveying direction. After the loop has penetrated, the rollers (8 and 9) move together, with the roller (10) being simultaneously lowered, as a result of which the winding space (12) for the lap rod (4) and the loop (13) is closed. The rollers (8 and 9), while being moved together, bring the inner faces of the hitherto open loop (13) into bonding contact with one another. The loop (13) closed round the lap rod (4) in this way is pressed against the lap rod by the rollers (8, 9 and 10) and set in rotation about the axis of the lap rod, the loop tightening round the lap rod and forming a first lap. After the initial lapping, the rollers (8, 9) move apart from one another again, with the roller (10) simultaneously being raised, and gradually open the winding space (12) to form a winding trough in which the lap increasing in size rests and is driven. <IMAGE>

Title: Device for fastening stock rails or travel rails in railway switches
IPC: E01B7/02
Filed: 1982-08-18
Abstract: A device for fastening rails in switches, namely both the inner stock-rail fastening and the inner travel-rail fastening in such switches, is to be equipped with elastic overload or tilt protection which prevents fractures on both the spring shackles and on the bed plates, irrespective of whether these are produced from individual parts in welded construction or in one piece as cast or forged parts. The bed plate (3) for the rail (1) carries a slide chair (8) for the switch blades and a clamping-plate fastening (4 to 7) on the outside of the rail foot (2). An essentially U-shaped spring shackle (17) for holding down the rail foot (2) on the slide-chair side can be pushed into a recess (10) on the underside of the slide chair (8), which recess (10) extends across the inside of the rail foot (2). In the clamped state of the spring shackle (17), the free ends (19) of the legs of the spring shackle (17) are secured by catch connection (14) to shaped portions of the slide chair (8), and located in the recess (10) on the underside of the slide chair (8) is a boss-like shaped portion (21') which acts as an abutment for the spring shackle (17) when the latter is clamped. In the clearance area (22') between the boss-like shaped portion (21') and the inside of the rail foot (2) a further boss-like shaped portion (21'') is provided on the underside of the slide chair (8). During normal restraint of the clamping shackle (17), the boss-like shaped portion (21'') has slight play (26) relative to the top side of the clamping shackle. But this slight play (26) is overcome during tilting stress on the rail (1) while forming a short lever arm (22'') at the spring shackle (17). <IMAGE>
