Title: Acousto=optical modulator - for speech signals with gradient lens and mirror membrane e.g. of teflon (RTM)
Inventor: WINZER GERHARD DR ING
IPC: G02B26/02
Filed: 1978-08-24
Abstract: An acousto-optical modulator for the modulation of the light intensity in telephone systems where many speech signals are transmitted by a time or frequency multiplex technique includes a gradient lens with a lens length equal to one-quarter of the pitch length. A reflecting surface of a mirror membrane lies opposite one of the front faces of the gradient lens and is angularly deflected by sonic action. The output conditions of the light input are varied in time to produce a light intensity modulation. This converts acoustical signals directly into optical signals without any electrical intermediary, ready for transmission by optical fibre light guides. The membrane is pref. made of 'Kaption', 'Teflon' or 'Hostaphan' (RTM).

Title: Turbulence jet for intermingling continuous filament yarns - within a cylindrical chamber closed by a rotatable slotted tube
Inventor: SCHUBERT GUENTER DR ING
IPC: D02J1/08
Filed: 1978-09-15
Abstract: A device for intermingling the filaments of a continuous filament yarn comprising slit which can be closed by means of a tube which fits within the chamber, having a bore of any desired cross-section, which also has a longitudinal slot similar to the one in the wall of the chamber, and which can be rotated by mechanical or pneumatic means to bring the two slots into alignment to allow a continuous yarn to be entered into the chamber without having to be threaded in from one end. This construction provides a simple means of closing the turbulence chamber in a manner which does not hinder the intermingling air jet or present the risk of snagging filaments. The air flow is automatically interuppted when the chamber is opened, and a group of chambers can be easily interlinded to allow simultaneous opening and closing.

Title: Drying machine for automatically washed glasses - takes dishwasher basket and blows drying air into upturned glasses
Inventor: BIERMAIER HANS
IPC: A47L15/48
Filed: 1978-09-16
Abstract: The drying machine for the glasses still stored in the crockery baskets but removed from the diswasher is set inclined in a resilient mounting where it can be set in vertical and horizontal vibration by a drive motor where upon air, pref. warm air, is blown into the upturned glasses. The vertical vibrations ensure that the water adhering to the surface of the glasses drains down much quicker whilst the still remaining film is evaporated off more quickly than with stationary glasses. The air blown into the inverted glass forces out the damp air. The horizontal vibrations ensure the glasses rotate in the basket tray so that drops forming around the bottom edge of the glass are wiped off by the rods which make up the tray.

Patent DE-2906670-A1 (DE)
Title: Load-compensated hydraulic control valve - has valves with common throttle member in union to hydraulic unit
Inventor: ZIRPS WILHELM
IPC: F15B13/04
Filed: 1979-02-21
Abstract: The valve provides load-compensated control of a hydraulic unit, having a control slide working in a housing and forming adjustable throttle openings. In the middle position this shuts off a union leading to the unit and in the end positions connects it to a supply or return union. Valves keep the pressure difference at the slide throttle opening constant independent of the pressure at the union to the unit resulting from a load on the latter, so that the value of the current flowing to this unionis dependent on the slide position. Second valves in the path from the unit union via the throttle opening to the return union likewise keep the pressure difference constant, and there is a control union in the housing. Both the valves have a common throttle member in the connecting passage between control slide and unit union.

Title: Sync. pulse generator for vertical deflection stage of TV receiver - only synchronises two frequency dividers when sync. pulses coincide with line frequency pulses
Inventor: MAI UDO
IPC: H04N5/06
Filed: 1979-06-13
Abstract: The sync. pulse generator has a frequency multiplier connected to the output of the line transformer. The multiplier is coupled via a first gate to a second frequency divider that synchronises a first frequency divider coupled directly to the multiplier's output. The second divider's output is connected to the set input of an RS flip-flop that controls the first gate. The flip-flop's output is connected to the input of a second gate whose second input is coupled to the receiver's pulse separation stage and whose output resets the second divider and the RS flip-flop. A third gate is coupled to the output of the RS flip-flop and to the output of the multiplier and its output is passed to a counter. The latter measures the duration of the set state of the flip-flop and set it in synchronism with a second flip-flop that opens a gate for the output pulses from the second divider.
Patent DE-2924087-A1 (DE)
Title: Measurement dial with adjustable scales - eliminates reading errors by having both scales readable w.r.t. null
Inventor: FALLER WOLFGANG
IPC: G01D13/10
Filed: 1979-06-15
Abstract: A measurement dial with adjustable scales for millimetres and hundredths is designed to prevent reading errors, e.g. for mfg. control or rotary machining (i.e. turning) applications. The actual measurement can be read w.r.t.null on both scales whereas on conventional instruments only the hundredths scale can be read in this way. A distance ring above the cover plate is connected to a larger milled ring via a driver. The drive disc moving the smaller scale is connected to a pin and parts of the larger scale. The drive pin engages the gear wheel and simultaneously turns the small scale. For a full rotation of the milled ring the small scale moves by one millimetre. Both scales can be returned to null by turning the large milled ring.

Title: UV curable scratch resistant coatings for thermoplastics - contg. polyunsaturated monomer and a photoinitiator, with heating during irradiation to improve adhesion
Inventor: KLEINE-DOEPKE WOLGANG DIPL CHE
IPC: B05D3/06
Filed: 1979-07-14
Abstract: Scratch-resistant coatings are applied to thermoplastic and thermoelastic substrates by applying a UV-curable compsn. comprising a radical polymerisable monomer with at least two polymerisable C-C double bonds (alone or mixed with other monomers contg. polymerisable double bonds with a b.pt above the curing temp) and a photoinitiator, and curing the coating by means of UV radiation at a temp between 70 deg C and the glass transition temp of the plastic. The process is esp useful for applying scratch-resistant coatings to polystyrene, rigid PVC, HIPS, polycarbonates, acrylic resins, etc., and esp to PMMA and polycarbonate glass. Curing the coating at elevated temp gives coating films with improved adhesion to the substrate.
