Title: Cleaning aid for rotating knife - using a fibre material strip wound into a firm roll which may be cut into slices
Inventor: FAITA EBERHARD
IPC: A47L21/00
Filed: 1975-09-09
Abstract: Aid for the mechanical cleaning of knife blades especially rotating blades used for cutting e.g. bread, sausage etc. consists of an absorbing fibrous cellular material. The fibre material strip is wound into firm roll (1) which can be cut into slices across the front surface. The fibre material strip has a smooth structure on either side and the outer end of the strip is firmly glued to the circumference of the roll. The strength of the fibre material strip varies between 0.04 to 0.2 mm, but is pref 0.06 mm, and the diameter of the roll corresponds roughly to the radius of the rotating knife to be cleaned less the radius of the knife hub.

Title: Reduced humidity air conditioning unit - has two stage electrically operated heat exchanger for air in closed circuit
Inventor: KEMMER JOSEF DIPL PHYS DR
IPC: F24F1/0358
Filed: 1975-09-25
Abstract: The method of air conditioning of completely or partially enclosed workplaces is carried out with a cooling unit and a secondary electrical heater. The air which is dehumidified and reheated by the cooling unit is blown into the work room, optionally after passing over the secondary heater and either passes out through working openings or is passed through a ground suction unit into a return pipe for recycling in a partially or completely closed circuite to the fan. In case of a closed air circuit, a very low air moisture content can be obtained, which even allows dewatering of the work materials. The installation may include a cooling unit with heat exchangers, a fan, a secondary heater, a run-off for water or condensation and switching pipes for a washing machine, to provide a closed air circuit which can be used for drying spun-dry clothes.

Title: Electromechanical filter with several special resonators - executes intercoupled orthogonal flexural vibrations
Inventor: KUENEMUND FRIEDRICH DIPL ING
IPC: H03H9/50
Filed: 1976-02-26
Abstract: The electromechanical filter consists of parallel rod-shaped mechanical flexural resonators lying in one plane and interconnected by coupling wires. Electrostrictive transducers are located at the input and output of the chain. One or more (4, 6) of the resonators in the chain executes two orthogonal flexural vibrations which are coupled to one another as a result of a deformation (16, 16') in the surface of that resonator(s). The advantage lies in using extra pole resonators without requiring the coupling factors of the input and output resonators to be increased.

Title: Ventilation control for caravan - has variable throughput roof fan and floor level grilles opening automatically according to airflow
Inventor: SCHOETTLER BENNO
IPC: B60H1/26
Filed: 1976-03-09
Abstract: The roof of the caravan is fitted with a motor driven ventilator in a resonance free mouting, and covered by an external cap. The cap lifts as the airflow through the ventilator is increased, and closes to conserve heat. Fresh air is admitted via floor level grilles in the side walls, with shutters to control the inflow of the cold air. The system prevents the build-up of suffocating CO and CO2, especially when cooking or sleeping. The variable cover and flaps conserve heating and prevent the inside of the van becoming too cold.

Title: Manual actuating mechanism for multiway valve - has lever with handle lockable to fixed structure to prevent operation
Inventor: BRAKEL KORNELIUS
IPC: F16K35/02
Filed: 1976-03-19
Abstract: The actuating mechanism for a multi-way valve has a handle (24) supported on a lever (15) and selectively lockable to fixed structure (19) to prevent operation of the lever. The handle is a rod having a hand knob at one end supported for axial and rotary motion in a bearing (18) on the lever. In the locked position of the handle, the other end of the rod engages a hole (23) in the fixed structure. Rotation of the knob about the rod axis releases a latch (33) and allows the rod to withdraw axially, under pressure of a spring (28), from the hole to free the lever for angular movement about its pivot axis.

Title: Tuning circuit for HF receiver with local oscillator - has tuning voltage varied so that rate of tuning decreases as required frequency is approached
Inventor: KLANK OTTO ING GRAD
IPC: H03J5/02
Filed: 1976-06-09
Abstract: Local oscillator is a VCO. In order to generate a tuning voltage a comparator compares a first number which represents the state of a counter which periodically counts the oscillations of the local oscillator, taking into consideration the i.f., with a second number fed through a coder to a store and representing the sender. The two numbers are compared digit by digit, beginning with the highest. A store (10) is provided for storage of the comparison result, and an amplifier (16) generates the tuning voltage from the store (10) outputs through resistors (11-15) of different values, so that the rate of tuning depends on the number of equal digits in the two numbers. This rate is high when all digits are different, and decreases as the number of equal digits increases.

Title: Charging and discharging of inductor - takes place through capacitor connected to AC supply via controlled rectifier and unidirectional switch is used
Inventor: MORI HARUMOTO DIPL ING
IPC: H01L39/14
Filed: 1976-10-07
Abstract: The object of the circuit is to remove the heavy currents associated with the charging and discharging of a highly inductive circuit from the supply system, and thus reduce the rating of the supply components. The problem is solved by using a capacitor as an intermediate energy store. The controlled rectifier (3), connected to an ac supply (R,S,T), feeds a capacitor (C) preferably through a smoothing choke (DCL). The inductive load (1) is connected to the capacitor via a unidirectional switch (S1, D1), and is bridged by a second such switch (S2, D2). With the first switch open and the second closed the capacitor charges to a set voltage at a rate determined by controlling the rectifier (3). The rectifier then turns off, the first switch closes and the charge is transferred to the inductor (1).

Title: Advancing pit prop and mine roof covering system - uses lubricated zigzag folded plastics sheets, successively overlapped to guard against roof falls
Inventor: LEWER HANS
IPC: E21D23/03
Filed: 1976-11-05
Abstract: An advancing pit prop system includes application of plastics, sheets to the roof as a protection against falls during operation. These sheets may be of polyethylene, and are folded in a zig-zag manner to form a bundle between 0.6 and 1 m thick. Each sheet is inserted between the top parts of the pit props so that it is overlapped with the free edge of a previously applied sheet. The pit props are then advanced, trapping the sheet, so that it is held in position. Lubricant can be applied between the sheets. Their thickness can be between 0.2 and 0.5 mm, their tear resistance is at least 15N/mm2 and elongation at least 4m/m or 400%. Alternatively, instead of a single sheet, two or three sheets, each 0.075 to 0.3 mm may be used on top of each other. A hygroscopic salt layer can be retained by the sheet.

Title: Wiped wall thin film evaporator - having all glass lined construction with PTFE wipers and distribution tray
Inventor: MITCHELL JAMES
IPC: B01D1/22
Filed: 1976-12-16
Abstract: Thin film evaporator consists of a cylindrical vessel with PTFE wipers on rotor operating on its inner surface to create a falling liq. film down the heat transfer surface. A distributor device above this surface serves to distribute the liquor over the surface. Both the inner surface of the vessel and the rotor are glass enamelled with corrosion resistant enamel. At least one distributor tray is provided on adjustable enamelled supports. The gap between the tray and the wall can be adjusted to create the desired feed effect. The supports extend to the outside and are sealed into the vessel wall. A number of parallel finger elements extend from enamelled rods made from PTFE. The centrifugal action of the rotating arms keeps these in contact with the walls. For use in evaporators where corrosive liquors are being treated.
