Title: Electronically controlled tennis ball delivery machine - has motor-driven friction wheels and braking system operated by programmed controller
Inventor: KOELLNER GUIDO
IPC: A63B69/40
Filed: 1979-11-12
Abstract: Tennis balls are delivered singly by a selector device to enter a channel which feeds them between two rapidly rotating friction wheels for discharge through a delivery slot in a front plate. Each friction wheel is driven by its own electric motor. The whole structure is mounted to rotate about a vertical axis, and to tilt about a horizontal axis. The friction wheels are braked by an electronically operated control system. The whole can be operated by a programmed controller and also be a remote control panel, enabling the programme to be varied.

Title: Mortarless synthetic material building block - is quadruple T=shaped with locking serration and optionally filled vertical cavities
Inventor: DEGENKOLBE DETLEF DIPL ING
IPC: E04B2/24
Filed: 1979-11-17
Abstract: Use is made of blocks made from any artificial material suitable to requirements, as rapid-building blocks to be stacked dry. They are of twofold double-T shape in plan, with internal vertical hollows. Dry stacking is facilitated by complementary serrations of elevations and depressions in bearing surfaces. If required, final bonding can be completed by filling resultant hollow columns with reinforceable concrete. Unfilled hollow columns can be covered with fitting panels, of aluminium or other~### materials, or by modified blocks. The blocks provide easy transition from one thickness to another, and can be strengthened where required, or insulated.

Title: Check valve for forced circulation pipe systems - with disc leaving specified passage area open in neutral position
Inventor: ROCEK JAROSLAV DIPL ING
IPC: F16K15/03
Filed: 1979-11-21
Abstract: A stop valve with a check valve disc for pipe systems with a forced circulation esp. for nuclear power stations, has this disc pivoted above the valve seat in such a way that the centre of gravity of the disc keeps the plane of its seating surface at an oblique angle to the vertical plane of the stationary valve seat.

Patent DE-2951183-A1 (DE)
Inventor: SCHMIDT SYLVIA DIPL-ING
IPC: D21F1/48
Filed: 1979-12-19
Abstract: A method and apparatus are disclosed for influencing the fibers in the uppermost layer of a fibrous web lying on a screen, for example, in applying a watermark or evening the surface of the web, wherein a surface compression is exerted on the web by a screen roller and a second screen guided around the screen roller. The surface compression is maintained over a variable time period and causes a water film to appear on the upper surface of the web, in which the fiber density is much less than in the web prior to the surface compression. This water layer is forcibly aspirated from the web and the fibers therein thus experience a reorientation and become set in desired positions.

Title: Increasing output of generator - placing copper tube filled by pressurised hydrogen in series with windings to act as charge carrier multiplier
Inventor: ELSAESSER WERNER
IPC: H02N11/00
Filed: 1980-01-23
Abstract: The modification is to obtain better utilisation of the energy provided by the primary power source. An avalanche condition increases the charge carriers above the level achieved by e.m. induction. The proposed device consists of a closed hollow cylinder of copper (1). Inside the cylinder is a copper spiral, or element, (4) electrically connected to it at one end (5) but insulated (7) at the other end (6). The cylinder is evacuated and filled with pressurised hydrogen. The copper element is pref. lithium coated. The element is connected in series with leads (10,11) from the machine windings. Current flow through the element creates an electric and magnetic field which ionises the hydrogen and builds up a flow of charge carriers to the cylinder walls. This increases the current flow leading to increase in field strength and thus in charge carriers in an avalanche manner.

Title: Industrial solvent recovery by condensing from compressed carrier gas - via expansion engine mechanically driving compressor for loaded carrier gas
Inventor: BARTH PETER DIPL CHEM DR RER N
IPC: B01D53/00
Filed: 1980-10-14
Abstract: The system comprises compressing a current of carrier gas contg. solvent vapour and then cooling to condense much of the vapour as separable solvent for recovery. The gas with residual solvent vapour is passed through an expansion engine partic. an expansion turbine, to produce mechanical energy. The expanded carrier gas is heated and recycled to pick up more solvent vapour for recovery. The mechanical energy derived from the expansion engine is mechanically transmitted to drive the compressor for carrier gas contg. solvent vapour. The mechanical energy derived from the expansion engine can be supplemented with energy from an external source to drive a single stage of compression. The energy from the expansion engine can be fully employed to drive the first stage of a two or multi-stage compressor. Subsequent stages are then driven by energy from an external source. Pref. the carrier gas is an inert gas, such as nitrogen, or a gas with an oxygen content below the limit which would support combustion of the solvent vapour. The installation is used to recover solvent vapours from industrial processes, partic. from the prodn. of paints and varnishes, adhesives and the chemical cleaning of textiles. A higher recovery rate of solvent is associated with a reduced energy requirement of the operation of the recovery plant.
