Title: Furniture and frame constructional kit - comprises strips drilled at regular intervals held apart by distance pieces
Inventor: HOLL FRANZ
IPC: A47D11/00
Filed: 1979-11-15
Abstract: The constructional kit is for furniture, play and tent frames etc, comprising perforated strips with holes (2) at regular intervals. These are used to form multiple strips (4) of two or more, held at a fixed distance apart by distance pieces (5), with the holes accurately in line, and connectors secure the strips together. The strips can be radiused at the ends. The distance pieces can be cylindrical washers whose bore diameter is the same as that of the holes and with coaxial cylindrical spigots (6) at the ends, fitting in mating counterbores (8) in the strips.

Title: Composite safety glass for windows, doors etc. - contains grid made of thick metal or rod remaining intact if panes are broken
Inventor: SCHAEFER BERND
IPC: E06B3/66
Filed: 1979-12-14
Abstract: Composite safety glass. An outer frame is employed to support at least one inner pane and one outer pane, both being made of glass or a polymer. The panes are sepd. by a spacer to form a cavity, in which a grid made of thick metal wires or rods is located; the grid is self-supporting. The length and breadth of the grid are pref. at least equal to the dimensions of panes; and the ends of the wires or rods are pref. located in holes in spacer. The grid wires or rods may be coated with polymer. Spacer may be located slightly inside the space between panes to leave an outer gap, which is filled with a sealing material. The grid rods pass through the sealing material and enter the outer frame. With conventional safety glass, the wire grid is relatively thin, so a roller shutter or similar safety device must also be used, e.g. to prevent entry or the theft of goods in a shop window. The invention uses a thick wire grid so no other safety device is required.

Title: Lightweight three=phase inverter - has transformer with three chopper stages with flip=flops controlling reference and delay flip=flops
Inventor: OTTO FRANZ
IPC: H02M1/08
Filed: 1980-02-25
Abstract: The three phase inverter powered by a l.v. source is lightweight and suitable for a light aircraft such as a glider. The circuit includes three chopper stages driven in sequence by a clock pulse device so that the d.c. voltage is converted into three phase shifted sections at the output of a transformer to give the required output voltage. The clock pulse device controls three controlling flip-flops in parallel at a frequency which is a multiple of the driving frequency, e.g. twelve times the driving frequency. The controlling flip-flops give an output voltage which is twice the driving frequency, and each controls a reference flip-flop which gives two square waveform pulses in phase opposition at the driving frequency. Between each controlling flip-flop and reference flip-flop is a comparator and a sawtooth generator interconnected with a delayed flip-flop in parallel with the reference flip-flop.

Patent DE-3102117-A1 (DE)
Title: Thread-tightener unit
Inventor: KOSLOWSKI GERHARD
IPC: B65H59/16
Filed: 1981-01-23
Abstract: In order to make both the high-frequency and low-frequency variations of the thread tension harmless during the winding of textile threads, there is proposed a thread-tightener unit, in which, in the thread running direction, first a rotational-energy accumulator looped round and driven by the thread and thereafter a looping-thread brake are arranged. The rotational-energy accumulator possesses a thread-deflecting device for the thread following up in the event of a thread stop. This prevents thread from winding round the rotational-energy accumulator as a result of its kinetic energy and inertia when the thread tension suddenly ceases. <IMAGE>

Patent DE-3112414-A1 (DE)
Title: Relay circuit
Inventor: STROBEL HUBERT
IPC: H01H47/32
Filed: 1981-03-28
Abstract: A relay circuit contains a relay having at least one switching contact and a magnetic coil operating the switching contact, the current supply for the magnetic coil being supplied by a current supply circuit. In order that the current supply circuit can operate over a wide operating voltage range and is suitable for its function without a transformer and without any deterioration of the efficiency, a switched-mode power supply, having two outputs to which a filter capacitor is connected, is provided in the current supply circuit. The inductance of the switched-mode power supply is formed by the magnetic coil of the relay which, together with a freewheeling diode connected in series with it, is connected in parallel with the filter capacitor so that the relay is triggered or tripped as a function of the current consumption at the outputs of the switched-mode power supply, depending on whether the current consumption is above or below the triggering value. <IMAGE>
Patent DE-3114861-A1 (DE)
Title: Separator for low-viscosity liquids; in this case, determination of the oil-film thickness in oil separators or the like (drawing off oil)
Inventor: HAMMERSCHMITT NIKOLAUS
IPC: B01D17/02
Filed: 1981-04-13
Abstract: In the separator chamber of an oil separator, the water level is displaced downwards by the oil, at a density of 0.85, by 5.6 cm for every 1 cm of oil above the water level, and, with the oil at a density of 0.90, the water is displaced downwards by 9 cm for every 1 cm of oil above the water level. In order reliably to delimit the oil-film thickness towards the bottom, there is arranged, in the region of the water-level fluctuations, a large-volume compensation vessel which receives the oil which overflows at the oil-column bottom at the lower overflow (010). In the case of the falling water level, this oil flows back into the oil-collecting chamber (21). With the following rise in water level, the oil flows away via the oil discharge (04). By constant repetitions, it is made possible to use the water-level fluctuations for drawing off the oil. This pump-like action is achieved in that a subatmospheric pressure is generated in the large-volume compensation vessel (21a), located in the region of the water-level fluctuations, by the sinking water level. The rising water level causes a superatmospheric pressure in the narrow cross-section of the oil discharge (04) which is likewise located in the region of the water-level fluctuations. The channel (02c) in the water-discharge cross-section favours the pump effect because the displacement is considerably increased without increasing the throughflow quantity. <IMAGE>

Title: Method and device for measuring the length of the distance travelled by a rotating running wheel of a vehicle and/or its speed
Inventor: HOLZHAUER BERND ING GRAD
IPC: G01P3/487
Filed: 1981-09-07
Abstract: This method and device are intended to make it possible to eliminate, on the one hand, the friction between a standing and a moving measuring part and, on the other hand, to improve the accuracy and form of indication. The method for this purpose is distinguished by the fact that pulses coming from a magnet rotating with the running wheel are supplied via a receiver, for example a reed contact or the like, to a computer and the latter calculates the linear distance in dependence on the size of the running wheel and its revolutions and outputs this distance to a digital display. The device comprises at least one pulse transmitter permanently connected to the running wheel, the path of movement of which is associated with a receiver which is stationary with respect to the rotational movement, for example a reed contact or the like which is connected to a digital display via a microprocessor or the like. <IMAGE>
