Patent DE-2751023-A1 (DE)
Title: Television tube beam deflection control circuit - has horizontal and vertical deflection signals cross coupled to improve vertical linearity
Inventor: HOLLANDER WILLEM DEN
IPC: H04N3/16
Filed: 1977-11-15
Abstract: The control circuit improves the linearity of the vertical deflection in a television tube by cross coupling the horizontal and vertical timebase signals. The horizontal deflection circuit (7,11) is cross coupled with the vertical control circuit (13 to 20,23,26, 27) through separate transformers (8) and (26,27). These circuits are coupled so that alternative larger and smaller portions of the horizontal control signal are transferred to the vertical circuit during succesive periods of the vertical deflection signal.

Title: Increasing the viscosity of aq. polysaccharide soln. - by pre-hydrating the polysaccharide in fresh water before mixing with hard water, useful as oil well flooding medium
Inventor: CARTER WALTER HARRISON
IPC: C09K8/90
Filed: 1978-03-03
Abstract: The viscosity of aq. solns. of polysaccharide B-1459 in hard water is increased by pre-hydrating the polysaccharide in fresh water before mixing with the hard water. The process is esp. useful for making up viscous aq. polysaccharide solns. for use as water flood media which are injected to recover oil from subterranean reservoirs. When making up these solns. in the field, it is often necessary to use water contg. a large amt. of inorganic ions (brine). The use of such waters normally gives lower viscosity solns. than fresh water. By prehydrating the polysaccharide with fresh water this problem can be overcome.

Title: Processing of semi-solid wastes from tar separators - by comminuting and milling to form pumpable suspensions
Inventor: OTTE ERNST
IPC: C10C1/00
Filed: 1978-10-02
Abstract: The lower layer of thick tar contg. lumpy solid waste prods is (a) drawn off from the tar separator, (b) the solid material precomminuted, (c) opt. mixed with raw tar from the upper layer and (d) finally milled to form a suspension of the solid matter in tar, which can be pumped, opt. after heating to reduce the viscosity.

Title: Hydraulic sole press for mfg. of footwear - has several steel strips between heel and toe press plates adapting to any shoe model
Inventor: LEIBROCK THEO
IPC: A43D25/10
Filed: 1978-11-03
Abstract: The adhesive-covered sole can be pressed with the heel on to the lasted upper by the press wherein between the hydraulically operated press plates (2, 3) in the sole and heel area near the arch there are several strips (4) which lie close together side by side across the sole. One or more of these strips (4) can be impinged upon by hydraulic pressure so as to move vertically together with the press plates (2, 3) for the sole and heel. Each two strips can be connected together by a double-armed articulated lever and connected to the piston rod of a hydraulic cylinder. Since the greatest difference in the shape of the lasts concerns the difference in height in the instep area it is now possible to adapt to this difference by using the required number of strips (4).

Title: Horizontal deflection circuit for TV receiver - has interdependent coupling with vertical deflection circuit via transformer
Inventor: HUGO ROLF ING GRAD
IPC: H03K4/83
Filed: 1978-11-23
Abstract: The horizontal drive output amplifier, apart from energizing horizontal deflection coils, also supplies the vertical coils with a basic current supply function via transformer coils. A control circuit, generating rectangular pulses of a frequency suitable for vertical line scanning, is used for modulating the energy supplied. A similar shaping circuit is provided for the horizontal deflection coils. They consist of a thyratron-diode pair controlled by the output of an operational amplifier whose inverting input is connected to the constant current charge pulse generator, and whose non-inverting input receives output from the saw tooth generator after passing through integrator stages. The latter produce the required parabolic impulse shape. The output of the differential amplifier consists of rectangular pulses whose pulse widths are modulated with the parabolic second input signals.

Title: Roebel bar winding for large AC machine - has winding rods curved between their offset at keyway outlet and their contact ends
Inventor: FREDERIKS WERNER DIPL ING
IPC: H02K3/12
Filed: 1979-02-17
Abstract: A bar winding is formed from specially prepared single rods. It is esp. for Roebel bar windings for large a.c. machines, esp. turbogenerators. The winding rods are curved in the flank region, namely, between their offset - bent at an angle - at the keyway outlet and their contact ends.

Title: Busy track safety system - has frequency-sensitive decoders with outputs fed to AND=gates to ensure spacing of vehicles within limits
Inventor: REBHOLZ WOLFGANG DIPL ING
IPC: B61L23/18
Filed: 1979-05-31
Abstract: The system is required for short distance traffic services where vehicles can travel between two destinations, but overtaking is impossible without causing complete breakdown. A number of control signals are gathered together along the track from the signal conductor, which can be a slotted guide working in conjunction with antennae on the vehicles. These signals are led to a central system which contains a receiver and decoding devices which are frequency sensitive. The outputs from the decoders are fed to and gates and thence to a transmitter which provides all vehicles with a coded permission-to-travel signal, thence to a receiver which lifts the brake of the relevant vehicle.

Patent DE-2922614-A1 (DE)
Inventor: VOGEL GERHARD ING
IPC: F25B30/02
Filed: 1979-06-02
Abstract: The number of revolutions of the drive motor of the heat pump is varied, making it possible on the one hand to adapt better to instantaneous heat requirements and on the other hand to exert less load on and improve utilisation of heat emission media. The regulating variable for varying the number of revolutions is derived both from the heat requirements and from the temperature of the heat-emitting medium. Curve (2) illustrates the heat and/or coldness supplied by a non-regulated heat pump, while curve (3) shows the heat and/or coldness supplied by a regulated heat pump as a percentage of the nominal output of the system, depending in each case on the difference between the desired inside temperature and the given outside temperature. According to curve (3), substantial adaptation of the heat supplied to the heat requirements is guaranteed, while taking into account the delivery capacity of the medium supplying the heat and with optimum utilisation of the change in the difference in performance due to the temperature difference. <IMAGE>
