Title: Thermal energy machine using compression principle - has separate units for compression and expansion with heat exchanger in exhaust from reciprocating expander
Inventor: DENS HORST
IPC: F02B33/44
Filed: 1992-06-11
Abstract: The thermal energy machine has separate units for the compression and expansion, one compression unit being able to supply several expansion cylinders. For compression, a rotary compressor is used whose rotor is cooled with fluid through a hollow rotor shaft. This gives good cooling of the air compressed so as to make the compression almost isothermal. The energy in the exhaust gas is passed to the compressed air by a heat exchanger after the compressor. After the heat exchanger is a non-return valve which generates an under-pressure (partial vacuum) in combination with the energy exchange in the heat exchanger, this also being used to create mechanical energy. USE/ADVANTAGE - For providing power, heat and cooling using single heat pump for small and medium plant in building. Low-loss, almost isentropic expansion gives excellent efficiency.

Patent DE-4303469-A1 (DE)
Title: SVHS video recorder
Inventor: KLUTH HANS-JUERGEN DIPL ING
IPC: H04N9/83
Filed: 1993-02-06
Abstract: An SVHS video recorder is constructed as a dual-standard device and also provides for VHS operation. Because of the different frequencies of the picture carrier in VHS and SVHS, two FM modulators are therefore needed during the recording and two FM demodulators during the replaying. It is the object to reduce the circuit expenditure for these modulators and, at the same time, to effect a compensation in the timing errors of the luminance signal. The modulation is effected on to a carrier with distinctly increased frequency, which is subsequently reduced to the frequency suitable for the recording by means of a mixing carrier (M1, M2), and the frequency of the mixing carrier is switched between VHS and SVHS operation. Particularly for an SVHS video recorder with an additional operating mode for VHS operation. <IMAGE>

Title: Device for recognising a thread in a channel through which air flows
Inventor: BOEHMER WALTER
IPC: D04B35/14
Filed: 1993-03-13
Abstract: The invention relates to a device of this type, particularly for use on cop-preparation appliances or feeders to a thread-piercing appliance, the channel cross-section being monitored by means of a sensor arrangement. The object of the invention is to improve the permanent reliability of such a device. This object is achieved, according to the invention, in that the transmitter (9) and receiver (11) of a sensor arrangement are arranged outside mutually aligned orifices (4) of a channel (1). An air gap (13, 14) is present between the outlet of the orifices and the radiation source and receiver respectively. Advantageously, the orifices are arranged on the smaller radius of curvature of a channel curve (2) and transversely relative to the curve plane. A carrier (5) for the sensor arrangement can be fastened releasably to a reinforcing insert (3) having the orifices. Contact with the thread or with the suction-air flow surrounding it in the channel is avoided by means of the external sensor arrangement. Particularly reviving agent which is carried along therefore does not reach the sensor arrangement. The air gaps allow cleaning without dismounting. <IMAGE>

Title: Method of regulating the position of a welding head above a weld
Inventor: KROTH EBERHARD DR
IPC: B23K9/127
Filed: 1993-05-22
Abstract: A method of continuously regulating the position of a welding head with regard to a weld to be produced by the welding head is described, in which the welding head arranged at a distance above the weld performs an oscillating movement superimposed on its linear welding movement, while the arc ohmic resistance varying with time or a variable analogous to it is measured, and a measure of the height of the welding head above the weld and of the lateral deviation of the welding head with regard to the weld is derived from the measuring signals, which measuring variables are fed into the control circuit. The method is characterized in that the measured values for the right-hand oscillation half-waves with respect to the weld are analyzed separately from the measured values for the left-hand oscillation half-waves with respect to the weld, and in that the one group of measured values thus obtained is fed into the control circuit as actual height values, and the other group of measured values thus obtained is fed into the control circuit as actual lateral values.

Title: Method for moving a rotating body
Inventor: FREUND MICHAEL
IPC: H02P8/22
Filed: 1993-06-15
Abstract: This is a method for moving a rotating body into a desired position. In an exemplary embodiment, a roll (12) of a printer (11) is brought by a stepping motor (13), via a drive device (14), into a predetermined desired position, the stepping motor carrying out a number of microsteps between the complete steps. The method is characterised in that to calibrate the stepping motor/drive device (13, 14), for each complete step of the stepping motor (13), the stepping error (advance non-uniformity) over a complete cycle is determined on the roll (12). To compensate for each stepping error, the necessary current ratio I1/I2 in the coils of the two-phase stepping motor is calculated and the number of microsteps for moving the roll (12) into its desired position is determined therefrom, is recorded in a table (21) and this is stored in a memory, and the data of the table are fed in association with complete steps as correcting values to the stepping motor control (23). <IMAGE>

Title: Electric motor
Inventor: LEHMANN RUEDIGER
IPC: H02P6/34
Filed: 1993-09-20
Abstract: An electric motor having a rotor which produces a constant magnetic field and having a stator with a plurality of coils which produce a rotating magnetic field, and at least one Hall element. The Hall elements (H), which control the current flow through the coils (S) of the stator (ST) of an electric motor, react not only to the magnetic field of the rotor (R) but also to the rotating field of the coils (S) of the stator (ST). This leads to the electric motor running irregularly and to a reduction in the torque. In order to achieve smooth running which is as optimal as possible and to achieve the maximum torque, means (M) are provided which screen the Hall elements (H) from the rotating field of the coils (S) or deflect the lines of force of the coils (S) such that these lines of force no longer pass through the Hall elements (H). The invention is suitable for electric motors whose rotating field is controlled by means of Hall elements. It is suitable in particular for capstan motors. <IMAGE>
