Title: Radial engine compressor with X and triangular reciprocating-piston rod guides on the coupled planetary drive
Inventor: SCHULZ WALTER
IPC: F01B9/02
Filed: 1982-03-02
Abstract: The light and short piston-rod drive pairs form four expansion spaces simultaneously in each cylinder. The piston rod bearing bosses are rotatably mounted with the uniform revolving finely toothed double planetary gearwheel on the pitch circle crankshaft, as a result of which the piston rods are guided backwards and forwards positively in a straight line. Fig. 1 shows an 8-chamber 4-stroke radial engine where the cylinder pairs are offset by 70 DEG  relative to one another and, via the planetary drive, produces an X-shaped stroke movement with an assymetric ignition sequence. Fig. 2 shows the three piston rod pairs, crossed in a triangle, of a 2-stroke radial engine controlled by means of the valves and scavenged by the high-pressure air from the blower, this engine pumps with the valves of the inner piston chambers as compressors or these can jointly form a 12-expansion chamber drive motor and, in the case of economy driving, the six co-operating inner-piston driving chambers can then be switched off. The reduced mass movements of the narrow piston-rod pairs float backwards and forwards between the explosion pressure drop and transmit only the converted torque outwards without damaging bearing loads and lateral piston friction pressures. This lightweight compact radial boxer engine compressor has a large volume and is suitable for high combustion force pressures. <IMAGE>

Title: Trailer train
Inventor: SCHMITT PAUL
IPC: B60D1/32
Filed: 1982-03-04
Abstract: In a trailer train which is composed of a towing vehicle (1) and an at least two-axle trailer (2), the trailer is coupled in an articulated fashion to a trailer coupling (4) arranged centrally at the rear of the towing vehicle (1). The front axle (5) of the trailer (2) is mounted in a bogey (6) which can be rotated about an axis of rotation (8) running at right angles with respect to the longitudinal central axis (7) of the trailer (2) as a function of the locking angle of the forked draw bar (3), and the rotary bearing (9) of said trailer being connected rigidly to the support frame (10) of the trailer (2). So that the distance between the towing vehicle and trailer can be selected to be as small as possible in order to reduce the air resistance and to increase the loading surface and so that, nevertheless, the ability to travel around bends and be shunted can be retained, it is proposed to couple the forked draw bar (3) to a steering part (11) which is mounted on the support frame (10) so as to be rotatable about an axis (12) which is offset in parallel on the longitudinal central axis (7) of the trailer with respect to the axis of rotation (8) of the bogey (6) towards the front side (16) of the trailer (2), and to equip the bogey (6) with a slide bar (15) which runs at right angles to the front axle (5) and intersects the axis of rotation (8) of the bogey (6) and in which a steering rod (13) is displaceably guided, which steering rod is coupled to the steering part (11) so as to be swivellable about an axis (14) running parallel to the axis of rotation (8). <IMAGE>

Title: Method for automatic adaptation of the volume and dynamic range of electroacoustic signals to the noise level occurring at the listening location
Inventor: PERSSON HANS-CHRISTIAN
IPC: H03G3/32
Filed: 1982-06-02
Abstract: By means of a control circuit with a relatively short control time, the level of the radiated useful signal is adjusted so that it follows the sum of the levels of the noise and the original useful signal, whereby simultaneous volume adaptation and dynamic range compression of the useful signal depending on the noise level with minimal additional sound pressure imposed on the listener and minimal reduction in reproduction fidelity are achieved. The circuit arrangement according to the invention provides an amplifier with a control component as a control route in the transmission path of the useful signal, while the control parameter is derived from the difference between the sum of the input level and the mean noise level on the one hand and the output level on the other hand.

Title: Circuit arrangement for generating axle counting pulses for axle counters
Inventor: BAUER FRANZ-LOTHAR ING GRAD
IPC: B61L1/16
Filed: 1982-06-21
Abstract: In a circuit arrangement for generating axle counting pulses for axle counters, use is made of a track instrument having two AC transmitter circuits in the form of anti-resonant circuits (L1/C1, L2/C2) connected in parallel. Coupled to each transmitter circuit is a receiver circuit (L10/C10, L20/C20) whose received voltage, which can be varied by the wheels to be counted, is further processed in an evaluation circuit. In this way, each of the two received voltages is fed after amplification and rectification to a convertor (U1 or U2). The convertors output an AC voltage whose signal frequency (F1, F2) varies with the magnitude of the DC voltage supplied. The signal frequencies (F1, F2) generated by the convertors pass via a band pass filter (BF1 or BF2) connected downstream of each convertor (U1 or U2) into a positioner (2) where the signals indirectly finally control an axle counting device as a function of direction. <IMAGE>

Title: Process and device for bonding synthetic turf sheets
Inventor: RUSSLAND HANS-JOERG
IPC: B05C5/00
Filed: 1982-07-17
Abstract: Perforated and therefore draining synthetic turf sheets are bonded to a prepared substrate in that the adhesive is applied in spots by the use of a perforated plate (1), through the holes of which said adhesive is allowed to drip onto the substrate. This avoids the holes in the synthetic turf sheet being filled with adhesive. In addition, this allows two-component reactive adhesives with a very limited pot life to be used. <IMAGE>

Title: Process for feeding an oil burner and oil burner for a firing plant
Inventor: DUEMPERT WALTER HORST
IPC: F23D11/44
Filed: 1982-11-03
Abstract: In an oil burner in which oil is supplied at a predetermined pressure by a pump to a nozzle which introduces the oil into a combustion stream, the oil being preheated before flowing from the nozzle, the oil is supplied to the nozzle by a pressure-raising device with a chamber in which the volume of the oil is increased by heating and partial gasification. It is thereby possible on one hand to reduce the predetermined pressure and hence the oil throughput, and on the other hand a more uniform combustion of the partially gasified oil results.

Title: Protective-earth conductor contact monitor for a plug-in, mobile protection device
Inventor: ZIELASKO HORST
IPC: H02H3/16
Filed: 1982-12-23
Abstract: The invention relates to a protective-earth conductor contact monitor for a plug-in, mobile protection device whose function is based on the principle of a residual current device (fault current circuit breaker) or differential current circuit breaker. The object is now to expand this protection device such that all the poles of a defective load apparatus are disconnected in the event of a fault current, even if the protective-earth conductor contact fails. The solution is regarded as being a monitoring circuit (10 or 20) which is connected in parallel with the protective-earth conductor contact (9). This monitoring circuit acts directly or indirectly on the tripping device (5) of the protection device. This ensures that disconnection results in the case of a fault current when there is a contact defect in the protective-earth conductor contact (9). <IMAGE>

Title: Ink jet printer
Inventor: HORIKE MASANORI
IPC: B41J2/21
Filed: 1982-12-23
Abstract: An ink jet printer with deflection control has a nozzle for ejecting an ink jet on the basis of the generation of oscillations and a deflection electrode which is arranged at a point at which an ink jet is divided up into droplets in order to be able to charge the individual droplets, the trajectory of the charged ink droplets being deflected in order to print desired data in a dot pattern. A number of nozzles is arranged in a direction of movement of an ink ejection head and a number of charge electrodes is arranged in accordance with the number of ink jets. Charged ink droplets are deflected by a deflection electrode which is assigned to all ink jets. A charge sensing electrode is arranged outside the field of movement of the ink jet head. A deflection control device compensates deflection of charged ink droplets by means of the output of the charge sensing electrode so that printed dots are aligned exactly with respect to one another. By means of a predetermined division method, image data are distributed to appropriate nozzles, and offset between the dots arising from the distance between the nozzles is compensated by the timing of the control of the application of charge current to the charge electrodes.

Patent DE-3314730-A1 (DE)
Title: Labelling machine for articles such as bottles
IPC: B65C9/10
Filed: 1983-04-22
Abstract: The invention relates to a labelling machine for articles such as bottles, with which bottles of different formats can be labelled. To this end, a dividing worm which is placed upstream of a turntable and is driven synchronously with the labelling machine can be switched from a single dividing distance to a multiple dividing distance. The series of articles to be labelled behind the dividing device is scanned to see whether it is a complete series or a series with a gap. The labelling station is controlled in dependence on the result of this scanning. If the series of bottles is complete, the removal elements which roll off from the front of a stack of labels can, as a result of the adhesive affect of the glue on their reception surface, accept a label in each rolling-off process and pass it on for application to the article. If, on the other hand, a gap in the series of bottles is ascertained, removal of a label in the rolling-off process is prevented by holding elements which operate on the front of the stack. In the machine according to the invention, it is therefore possible, without conversion of the removal elements, to label bottles of different formats on the same labelling machine. <IMAGE>

Title: A scrapeable piston pump
Inventor: CUKROWICZ FRANZ
IPC: F04B53/00
Filed: 1983-05-19
Abstract: The pump permits cleaning by means of a go-devil, without first having to open it. Inlet and outlet are controlled by slide valves (3 and 4), in which the pipe connection (1 and 2) is made axially and the liquid passage (11) is formed like a pipe bend. The control slide valves (3 and 4) are connected to one another by control ducts (5 and 6), these being led past the pump cylinder (7) so that they project with their cross-section into this thereby forming inlet and outlet apertures (10). The drive chain wheels (14 and 15) designed as a detachable keyway connection, of the control slide valves (3 and 4) can be engaged and disengaged by means of the threaded drive (18) and of the disengaged lever (17). In this way the control slide valves (3 and 4) can be brought either into the operating position or into the scraping position regardless of the position of the pump piston (8). Recesses (9) in the piston (8) mean that when scraping in the limit position of the piston the associated control duct has a circular passage. <IMAGE>

Title: Chain lock for round-link chains underground
Inventor: GARTE RUDOLF
IPC: E21C29/04
Filed: 1983-07-04
Abstract: Round-link chains according to DIN 22252 are installed underground for conveyor and cutting systems for the purpose of obtaining an endless chain as connecting members. These connecting members are the weakest link in the chain, because they have no expansion, also have a fastening which is not technically efficient and are held together by clamping pins which reduce the cross-section and, moreover, also quickly become rusty, this having an adverse effect on the dismantling. In principle, chain locks in cutting systems are regularly exchanged for new chain locks after a specific operating time, thus, for example, after 14 days. According to the invention, the abovementioned disadvantages are eliminated in that the chain lock possesses a continuous chain-link leg which has a smaller cross-section curved towards the centre, that is to say resilient, which absorbs the expansion of the chain lock. A high tensile force and a high bending moment are achieved with the rotatably mounted spline-shaft/spline-hub connection. The chain-lock connection with the spline-hub toothing receives two friction plates which serve as a safeguard against rotation and which thus make clamping pins unnecessary. The chain lock thus consists of two assembly parts, namely the chain shackle and the connection piece, and is therefore simple to mount and dismantle.
