Title: Circuit arrangement for generating a pulse-width-modulated pulse train
Inventor: KLINGENBERG WOLFGANG ING GRAD
IPC: H03M1/00
Filed: 1982-08-27
Abstract: To relieve a digital control (1) which is used for the digital generation of a pulse-width-modulated pulse train, a signal sequence of "1" and "0" signals representing the respective on and off duration of the pulses (duty ratio) is transmitted in parallel by the digital control (1) into a buffer store (2) which can be read out repeatedly. A shift register (3) is reset with the contents of the buffer store (2) whenever the last of the signals output serially out of the shift register (3) as determined by a shift clock, is shifted out, a change in the buffer store contents occurring only when the duty ratio of the pulse in the pulse train to be generated is changed. The pulse train which can be picked at the serial output of the shift register (3) can be used, for example, for driving a direct-current motor (6) via a motor bridge circuit (5). <IMAGE>

Title: Wire take-off device for intermittent operation and high degrees of nonuniformity
Inventor: LIEKMEIER FERDINAND DIPL ING
IPC: B21C49/00
Filed: 1982-09-23
Abstract: The invention relates to a motor-driven wire take-off device which is equipped with two compensators and hence allows continuous unwinding from the wire coil despite high degrees of nonuniformity in the demand for wire by the following machine. The compensator devices are connected up to one another in such a way that one compensator only compensates the nonuniformity without exercising control, while, during this process, the second compensator remains inhibited. Only after a limit position is reached is this second compensator released and, in addition to further wire take-off, also brings about a control pulse which changes the continuous take-off speed of the drive. This double-compensator device can operate both with simple take-off drives and with calibrating wire-drawing machines connected in between.

Title: Charging device
Inventor: OEJELID GOERAN
IPC: H02J7/02
Filed: 1982-10-02
Abstract: The invention relates to charging devices for electrical accumulators. An object was to achieve a charging current which is largely independent of the internal resistance and charge state of the accumulator as well as of voltage fluctuations of the mains, and to reduce this current automatically when more than 90% of full charge has been reached. A further object was the arrangement of a measurement of the rising accumulator voltage during charging which is sufficiently precise and easy to read off that the charge state can be determined thereby. A further object was to facilitate the individual charging of a plurality of simultaneously connected accumulators using only one charging device. The objects are achieved particularly economically by a special thryistor circuit which is supplied with the multiple voltage of the accumulator, a high precision digital voltmeter, matched thereto, and an electronic stepping switch.

Title: Device for milling a helical groove in the side wall of a predrilled hole
Inventor: BUSSMER PETER
IPC: B23B51/00
Filed: 1982-10-22
Abstract: It is often necessary to fasten bolts in bores of marble tread plates of overhanging stairs and also other workpieces made of a similar material, for example connect two successive tread plates. The invention describes devices, by means of which it is possible to mill in the side wall of such bores designed as a blind hole helical threads into which correspondingly shaped adaptors, especially coupling members for two successive tread plates, can then be screwed. In a device for milling this helical groove, the spindle of the milling cutter (14) is driven by a motor (9) which is carried on a frame (1) attachable to the constructional part, the cutter axis being mounted so that it forms an acute angle with the axis of the bore (15). Provided on the frame (1) is a guide piece (3) which carries a screw thread (4) and which is arranged rotatably relative to the counterpiece (5) carrying a corresponding counterthread and connected firmly to the frame. The arrangement is such that, as a result of the rotation of a handle piece (17) and the helical movement of the counterpiece (5), a mounting of the cutter axis is so pivoted or moved on a circular path that the cutter axis (13) describes a helical surface (Fig. 1). <IMAGE>

Patent DE-3301863-A1 (DE)
Title: Fan heater with throughflow or circulating heating in tunnels equipped with heating wire
Inventor: REIBER KURT
IPC: F24H3/04
Filed: 1983-01-21
Abstract: The air to he heated is intensively heated to the maximum extent in the tunnel throughflow process along the heating wire on the whole spiral tunnel length. The heating air thus heated can be used for space heating or else for individual purposes, e.g. as a hot blower, for disinfection, for heating fuel oil up to the flame point and for hot-air supply to the oil burner, for heating baking ovens, the still hot baking-oven air being tunnel-heated again in the circulation process, and in general anywhere where large quantities of heat are quickly condensed. Hot-air ventilation is required. Additional power is saved when there is a reduced pressure in the tunnel space, since the air can then take up heat more readily and on reversion to normal pressure increases by a further few degrees of heat. The conversion of the electrical energy into heat energy takes place in the tunnel fan heater with a high efficiency, which means saving power. The drawing shows the fan heater made of three ceramic parts and without a ventilation device.

Patent DE-3321119-A1 (DE)
Title: Hydraulic drive device
Inventor: SCHULZE ECKEHART
IPC: B23Q5/36
Filed: 1983-06-10
Abstract: A hydraulic drive device is specified which comprises a double-acting hydraulic cylinder as a drive part and an electrohydraulic follow-up control valve as a control part which, with an electrically controllable preset desired value and mechanical actual-value feedback, controls the working stroke of the hydraulic cylinder via an elongated measuring spindle which also performs the movements, for example, of the tool or workpiece and is arranged so as to run along the central longitudinal axis of the valve housing. The housing is flange-mounted on the respective fixed machine element via an intermediate piece which is in good thermal contact with the measuring spindle. It is made of a material which has a greater coefficient of thermal expansion than the spindle material, and the axial length of the intermediate piece is selected in such a way that a temperature-induced length change of the intermediate piece corresponds to the length change of at least that section of the spindle which is equal to the minimum axial distance of its end which can be coupled to the moving part from a driving member which sits on the spindle and whose displacement brings about the axial shifting of the valve-actuating member. Optimum temperature compensation is obtained for a defined value of the working stroke of the hydraulic cylinder.
