Patent DE-2751276-A1 (DE)
Title: Control circuit setting movable component in certain position - has position pick=up whose signal is compared with signal representing required position
Inventor: HIRSCHMANN JOSEF
IPC: G05D3/18
Filed: 1977-11-16
Abstract: The component moves along a certain path, driven by an electric drive. The device has a position pickup generating a feedback signal representing the position of the component. A comparator circuit is used. It compares this feedback signal with an input signal representing the component nominal position. Its output signal controls the electric drive system. The input signal (E) representing the nominal position is applied to the comparator (4) input through a limiter circuit (7). This circuit is used for limiting the rate of rise of this signal.

Title: Measurement and control for fluid flow valve position - is performed by logic circuit permitting energy consumption calculation
Inventor: LENZ KARL
IPC: G05D23/19
Filed: 1978-01-09
Abstract: The operation of a valve in a fluid flow is controlled and measured in order to provide control and measurement of energy consumption. The position of a valve (14) in a fluid flow (12) is measured and controlled (18, 20, 22, 32) by a logic programming circuit (26) to which a position sensor (48) is connected via a multiplexer. Temperature sensors (40, 42) measure temperature of the fluid inlet and outlet flow in order that energy loss may be calculated for control of valve when compared with predetermined value. Fully closed and fully open valve positions are indicated and intermediate positions determined from a control low curve to permit control of fluid flow.

Patent DE-2846998-A1 (DE)
Title: Cartridge, e.g. for practice use, which sheds mass - giving short range with initially realistic ballistic behaviour
Inventor: BUGIEL HORST-GEORG DIPL ING
IPC: F42B8/14
Filed: 1978-10-28
Abstract: Inside the cartridge e.g. to achieve reduced range, the bullet is coupled through an element made from a resilient substance to a ballast weight or weights. The later release of the energy stored in the resilient element by the firing impulse causes the ballast weight(s) to be thrown off. The resilient element may be mounted in a contg. cavity formed in the rear face of the bullet. By the use of an under-calibre bullet a design which allows the gas force to impinge directly on the rear ballast weight may be used. The bullet may be of multiple type. Combination of inertial mass and elasticity in the system can produce a simulation of the ballistics of service ammunition in the initial trajectory while the loss of weight in flight leads to a shortened overall range. The cartridge is suitable for safe use on small practice ranges and may be given more realistic ballastic performance than the lightweight ammunition normally supplied for this purpose. System may also be used for sepg. multiple-type bullets or to control flight-path by suitable design of the angle of throw-off.

Title: Ironing press for textile sandwich contg. electrical heating strip - has resilient heat resistant facing to receive needle points of template
Inventor: ALTMANN DIETER
IPC: H05B3/36
Filed: 1980-04-10
Abstract: An ironing press is intended for bonding fixed electrical conductors into a sandwich fabric, using a hot-melting adhesive to fix the conductor in position. The pattern of the conductor (7) is fixed by a needle board (4), in which the projecting needles (5) form a template around which the conducting strips or wires are wound. The sandwich (8,9) is pushed onto these needles and the upper pressing plate (3) descends to heat the glue. The pressing plate (3) is faced with an elastic, porous blanket (12) of material possessing the necessary heat resistance to withstand the ironing temperature, bonded by adhesive (11) to the pressing plate. The elastic behaviour of the blanket (12) is such that the needles (5) can penetrate into it without damage and withdraw again as the press is re-opened. The needle board or template (4) can have fixed needles, and thus requires no intricate mechanisms to enable the needles to be pushed back into it during pressing.
