Title: Meat section cutting machine - hahas spiral shaped er protruding from housing slit in which it rotates
Inventor: KUBALEK SEN MIROSLAV
IPC: B26D1/28
Filed: 1975-07-29
Abstract: The cutting machine consists of a housing in which a spiral shaped cutter blade is mounted behind a lost in the housing. The meat can be placed on a table mounted normal to the housing. The shortest radius of the spiral is equal to the distance of its centre of rotation to the side of the housing so that when the blade rotates, its edge will gradually protrude further through the slot until it has completed one revolution and is again flush with the housing. A guard is mounted over the cutter blade, which when swung into position will switch the drive motor on for one revolution.

Title: Instrument protection by cooling - is esp. for radiation pyrometers and uses water jacket around instrument to release protective shield
Inventor: VOGT HANS-WILHELM
IPC: G12B17/00
Filed: 1975-08-02
Abstract: The methods of cooling are for instruments, typically radiation pyrometers mounted in environments receiving a large amount of radiated heat. The methods depend on cooling the instrument with water or air and interrupting the radiation with a shield should the coolant flow fail. The water coolant (4) is fed throught a jacket round the instrument (1) and then through a U tube (16), the weight of which holds a latch (11) in place and this holds a shield (8) out of the beam of heat radiation (12). If the coolant runs out, the latch (11) trips and the shield falls into place. Other arrangements involve spring loaded pistons (41) mounted in cylinders, which release a shield (30) when the coolant supply fails, or which use a coolant motor and fan (53) supplied by an electric supply (65) which also holds a shield (50) out of the beam by an electromagnet (64) and pulley (60).

Title: Motor vehicle tyre with increased directional stability - with tread surface incorporating suction chambers with air slots
Inventor: VOLLSACK ERHARD
IPC: B60C11/117
Filed: 1976-01-07
Abstract: Motor vehicle tyre has incorporated in its tread surface suction chambers with air slots, which have any geometrical shape and of which the suction area is greater than the base area. The junction between the suction chamber wall and the tread surface may have a curvature which coressponds to any geometrical curve. The suction including the air slots is pref. shaped according to the laws of fluidics. The air slots pref. open out in the contour line of the suction chamer. In operation, the air slot first contacts the road. Due to compression of the tread material, air flow causing air displacement is created in the air slot and in the suction chamber. If chamber and slots are covered by the roadway, there is min. partial pressure in the chamber, sufficient to prevent lateral sliding of the tyre.

Title: Hand control for hydraulic brakes - has simple change-over switch to select foot- or hand control
Inventor: VENTURINI GIANCARLO
IPC: B60T11/18
Filed: 1976-02-21
Abstract: The vehicle is fitted with both foot pedal control brakes (p) as well as hand lever (11) control.

Title: Bright annealing steel in vacuo or inert gas - using long preheating cycle to remove organic matter from surface of steel
Inventor: PFENDER KARL
IPC: C21D1/74
Filed: 1976-08-12
Abstract: In a process of annealing metals, esp. bright-annealing steels in bell-type containers or pots moving laong a row or round a turntable, the preheating step to 400 degrees C in one or more pots in vacuo or inert gas, for evapn. of hydrocarbons adhering to the surface of the steel, is equal to or longer than the charging, annealing, and cooling steps. Pref. the charging step is shortened and the time saving is used in the preheating step, esp. when using a separate station for each step, where preheating occurs both in the charging station and in the preheating station. Alternatively, six stations are used, employing two stations for preheating and cooling and one station each for charging and annealing.

Title: High speed data processor ink transfer roller - has porous sponge structure shielded to control ink ejection by centrifugal force
Inventor: MUELLER HEINZ
IPC: B41J27/12
Filed: 1977-03-11
Abstract: The ink transfer roller for a high speed data processing system is designed to avoid scattering and wasting of ink. It comprises an open porous sponge-like plastic material whose pores contain the ink which is ejected from the roller by centrifugal force as it rotates. The roller surface is partly shielded so that ink can only be ejected in metered amounts. The pores on the flanks of the roller are sealed off by fusion, coating, or marking. The roller surface can be covered with a metal powder which only permits metered amounts of ink to leave the roller surface during rotation.
Patent DE-2713041-A1 (DE)
Title: Pulse generation in axial pulsed gas laser - voltage pulse rising time is synchronised with gas breakdown, ensuring laser pulse reproducibility
Inventor: WLADIMIROFF WLADIMIR DR
IPC: H01S3/097
Filed: 1977-03-24
Abstract: The laser is pumped by voltage pulses reaching a peak after a given rise time. Each laser pulse is generated by a gas breakdown at the end of the breakdown period. The continuously rising edge of the voltage pulses during the whole breakdown period is so controlled, that the peak is reached at the instant at which the laser gas conductivity abruptly rises at the end of the breakdown period. Thus the voltage pulse rising time is synchronised with each gas breakdown, and laser pulses are generated with max. reproducibility. The laser tube is connected to an inductance (L1).
