Title: Heat engine
Inventor: KLEINWAECHTER JUERGEN DIPL PHY
IPC: F02G1/04
Filed: 1985-03-12
Abstract: In a heat engine, especially a Stirling engine, comprising a displacement piston and a working piston which, coupled to one another, are arranged, linearly guided so that they are capable of oscillating in a housing tightly sealed off from the outside, the gas space between displacement and working pistons being connected to the gas space between displacement piston and housing by way of a heater, cooler, regenerator arrangement, and an external heat source being connectable, in order to permit a problem-free output of mechanical energy through the closed housing to the outside, it is proposed that a magnetic or magnetisable coupling device (9, 15), arranged inside the housing (1) be connected at least to the working piston (2) and that a corresponding magnetic or magnetisable coupling device (8, 18) be movably supported outside the housing (1) parallel to the piston travel. In order, in particular, to be able to control the oscillation behaviour of working piston and displacement piston in each operating phase, it is further proposed that a device for setting the phase position between working piston (2) and displacement piston (4) be formed by a magnetically coupled mechanical mechanism, especially a crankshaft mechanism. In particular, it is proposed that from the translatory movement of the pistons, a rotational movement, transmitted to the said pistons, be measured, ... Original abstract incomplete. <IMAGE>
Patent DE-3511302-A1 (DE)
Title: Grille or mat as floor covering
Inventor: ARENS HORST G
IPC: E04F19/10
Filed: 1985-03-28
Abstract: A grille or a mat which is used as floor covering and has a multiplicity of grid openings delimited with respect to one another by up-ended webs can be designed in an anti-slip manner by using stoppers consisting of non-slip material. In this arrangement, each stopper has a shoulder or collar and a shank. The shank has a cross-section corresponding to the grid openings and is of a length which slightly exceeds the height of the grille or mat webs. The shoulder or collar projects laterally beyond the shank by an extent which corresponds approximately to half the thickness of the grille or mat webs. During walking on the grille or the mat, the shoulders or collars form the anti-slip means on the upper side, while the ends, of the shanks, projecting from the underside become the anti-slip means of the bearing surface. To maintain the spacing between the grille or the mat and the bearing surface, other stoppers can be used which have a neck and a base and engage from the underside into the grid openings of the grille or of the mat.

Patent DE-3529404-A1 (DE)
Title: Rotor transmission for wind power stations
Inventor: ECKERT RUDOLF
IPC: F03D80/70
Filed: 1985-08-16
Abstract: The rotor transmission fulfils all requirements made of it. It translates the slow speed of the rotor transmission housing into a fast output speed. This is achieved by the rotating transmission housing with the necks of the rotor blades. The main shaft is a recessed hollow shaft and is clamped to the tower jib. The internally toothed gear rim is bolted to the transmission housing; it drives the small gear wheel on the countershaft. This is rigidly connected to the large gear wheel. Due to the recessing of the hollow shaft, the large gear wheel drives the working shaft by way of the pinion. The bearing of the countershaft is rigidly connected to the main shaft. All toothed parts are designed for changing in order to double the service life. Brake disc or brake drum are bolted directly onto the rotor transmission housing. The rotor transmission absorbs the forces acting from all directions equally well. It is therefore suitable both as a leeside and a windward-side rotor. It lends itself to series construction in various sizes and can be used on its own or in a plurality of power units.

Title: Multi-chamber light for vehicles
Inventor: THIEMANN HUBERT
IPC: F21V19/00
Filed: 1985-08-30
Abstract: In the case of a multi-chamber light for vehicles, the incandescent lamps are connected by cables to one another and/or to a multiple plug. The collar, which holds the incandescent lamp, of the individual reflectors has at least one holder for a contact spring. The holder and the contact spring are designed such that the contact spring which is inserted into the holder is locked except for the direction from which it is inserted. Seen in the insertion direction of the spring, two slotted wall parts are arranged on the reflector collar laterally adjacent to the contact spring, the slots in which wall parts run at right angles to the insertion direction of the contact spring. These slots hold the cable in a clamped manner resting against the contact spring, so that the contact spring is also fixed in the direction from which it has been inserted. The welding between the cable and the contact spring is not carried out until the contact spring and cable have been inserted.

Title: Method and circuit arrangement for receiving data signals occurring on a transmission line used in time division multiplexing
Inventor: HABERER HERBERT DIPL ING
IPC: H04J3/16
Filed: 1985-09-18
Abstract: To control the reception of data signals occurring in time slots of a transmission line (Ltg) used in time division multiplexing in reception channels (EK1 to EKn) provided for these data signals, a bit string is defined for each one of the reception channels which has a number of control bits permanently allocated to the time slots associated with a pulse frame which corresponds to the number of these time slots, through the occurrence of which control bits in a specific binary state the occupancy of the associated time slot is in each case displayed as a reception time slot for the respective reception channel within the pulse frame concerned. The control bits of the bit string in each case associated with the reception channels are made available consecutively and in cyclically repeated fashion in consecutive pulse frames in the timing pattern of the time slots. The data signals occurring on the transmission line (Ltg) in time slots which correspond to one another are in each case accepted only by the reception channel for which the relevant time slots are marked as reception time slots by the binary states of the control bits allocated to these time slots. <IMAGE>

Title: Process for producing ventilation hoses
Inventor: JAEGER ANDREAS
IPC: B29D23/00
Filed: 1985-10-19
Abstract: The invention starts from a process for producing ventilation hoses which are provided with a multiplicity of fine slits for the passage of air and are held by clips on a support tube. To improve this fastening, that is to say to prevent detachment of the hoses, according to the invention the still unslit hose bodies are finally dimensioned by heat treatment after their vulcanisation. This may take place at a temperature of 50-150 degrees Celsius for 12 to 48 hours. Hoses are thus obtained which are very dimensionally accurate and can therefore be readily fastened.
Patent DE-3618318-A1 (DE)
Title: Hypodermic syringe
Inventor: RAU ROLAND DR MED
IPC: A61M5/315
Filed: 1986-05-30
Abstract: A hypodermic syringe (1) (Fig. 1) is used, initially, for the separate storage and, subsequently, for the administration of two injectable media (9 and 10). At the same time, part of a first liquid (9) can be ejected, and this is followed by mixing of the second liquid (10) with the left-over remainder of the first liquid (9) and, finally, expulsion of this mixture. This entire process results from a continuous advance operation by pressure upon a thrust rod (7). In order to obtain this sequence, releasable stop elements (11) which act in the movement direction of the hollow piston (6) in an interim position in the course of its displacement path are provided between the hollow piston (6) and the barrel (2). The hollow piston (6) can thereby be advanced up to an interim position in which these stop elements rest against each other. In this position, excessive engagement is prevented by support of the advancing piston (8) located in the region of stop projections (11a) on the inside of the hollow piston (6). This results in a pressure increase in the hollow piston (6), so that it can burst open at its front (12) at intended breaking points (13). The two liquids (9 and 10) are then mixed and, finally, when the advancing piston (8) has left the region of the stop elements (11) the mixture comprising the first and second liquids (9 and 10) can be completely...

Title: Device for transporting ink ribbons in typewriters or office machines of similar design
Inventor: LANGE HEINZ
IPC: B41J33/26
Filed: 1986-05-31
Abstract: Devices for transporting ink ribbons in typewriters or similar office machines are intended always to guarantee a reliable transportation of the ink ribbon and should additionally be cost-effective and favourable in assembly. The invention guarantees an expedient design of the ink-ribbon transporting devices due to the fact that both ends (32, 33) of a finite toothed belt (17) are attached in each case by a clamping piece (34, 35) releasably to side walls (36, 37) in the machine frame, and that a spring (38) is arranged spread out at least between one clamping piece (34, 35) and the assigned side wall (36, 37). The toothing of this toothed belt (17) is always engaged with a gear wheel (16) by means of which a transporting roller (21) which drives the ink ribbon can be driven in the simplest manner during the movement of the carriage (1). <IMAGE>
Patent DE-3622482-A1 (DE)
Title: Wire cutter auxiliary device
Inventor: ROTH WOLFGANG
IPC: B23D57/00
Filed: 1986-07-04
Abstract: Wire cutter auxiliary device for machines (machine tools), which can be coupled, for the purpose of cutting by wire by means of cutting wires of the most varied design (machining method) and any geometry, to components (most varied materials) with the aid of at least one of the motor and drive devices present on the machine. The device is used to machine components by means of a cutting wire moving round or to and fro in the device. This cutting wire performs corresponding cutting work during the passage of an operating section (see also sketch). The particular advantage of the device is that it can be mounted as an auxiliary device at any suitable point on an existing machine and uses at least one of the existing movement axes as a feed. The drive for the rotating wire can either be taken from the machines or is produced by means of an integrated motor. The circular geometry of the wire permits arbitrary contours to be cut. Owing to the slight cutting width of the wire, both the expenditure of energy and the metal-removal rate are very low. A design resembling an angle scanning unit permits even difficult geometrical conditions to be taken into account without high outlay. The low cutting forces permit a high lability and minimum stabilisation (devices) of the components. <IMAGE>

Title: Die orifice for extruding a ceramic composition
Inventor: MUELLER HERBERT
IPC: B28B3/26
Filed: 1986-07-05
Abstract: A die orifice (1) for extruding a ceramic composition to form honeycomb bodies has a die body (1) in which feed channels (21) are provided on the inlet side (E) and, on the outlet side (A), outlet channels (31) are arranged in the form of a grid. The mould body (10) comprises individual core segments (11) of plate-shaped design; the feed channels (21) are in this arrangement formed by cutouts (22, 23) which run in the flow direction (S) of the ceramic composition and axially perpendicular thereto and are provided on the outsides of said core segments (11), and the outlet channels (31) are formed by slits (32, 33) which run between the individual core segments (11) and are formed in the latter. In addition, the core segments are clamped by means of tie bolts (16) between two clamping strips (14, 15) which are fastened in a receiving plate (2). By virtue of this design, it is possible to produce the die orifice (1) very economically and also from wear-resistant materials. It is also very easy to influence the flow behaviour of the ceramic composition and it is possible to exchange damaged parts of the die orifice (1) in a short time. <IMAGE>

Patent DE-3639174-A1 (DE)
Title: Hydraulic control device
Inventor: SCHWERIN GUENTHER
IPC: F15B13/04
Filed: 1986-11-15
Abstract: A hydraulic control device (10) with control spool (34), hydraulically pilot-controlled stop block (15) and choke valve (13) is proposed which in the lowering position enables control pressure to be produced largely free of leakage flow for actuating the push-open piston (17) in the stop block (15). The choke valve (13), working as a pressure balance in the lifting position, works during lowering as a pressure reducer whose regulated outlet pressure in the outlet space (23) is fed by the control spool (34) to a pressure space (57) at the push-open piston (17), while the spring space (24) at the choke spool (18) is relieved to the tank (48). To this end, the control spool (34) has two oblique passages (78, 79), passing through several piston sections (58, 65, 67), and control notches (76, 77) lying offset on the same piston section (65). Instead of a continuous leakage flow, only small control-oil quantities are required for regulating movements of the push-open piston (17) so that the control device (10) works in an energy-saving manner irrespective of the respective pressure of the variable displacement pump (81). <IMAGE>
