Inventor: EICHENHOFER KURT-WILHELM DR
Filed: 1974-05-22
Abstract: Ketazines (R1)(R2)C=N-N-C(R1)(R2) (I) where R1 and R2 = opt. branched, opt. substd. (cyclo)alkyl or aralkyl gps. with =12 or R1 and R2 may form part of a 5-10C alicyclic ring system or one of the gps. R1 and R2 = opt. substd. aryl gp. with =10C, are made by reacting H2O2, a ketone R1R2CO and ammonia in the presence of ammonium carbamate (II). The (II) acts as catalyst and is stable to hydrolysis in the presence of ree NH3; the co-product of the process, ammonium carbonate, can be reconverted into (II) and all other unconverted reaction components can be recycled.

Title: Pneumatic nail driving fixture - has nail store with feed and drive operated by pistons
Inventor: SATO TUTOMU
IPC: B25C1/04
Filed: 1974-08-14
Abstract: The nail driving fixture consists of a housing with handle and operating lever. A drive system is mounted in the housing which consists of a piston to which a nail driving mandrel is attached. This mandrel is in line with the nail to be driven in.

Title: Vibration generator for process equipment - with energy stored in elastic spheres fitted with transducers
Inventor: MASAO INOUE
IPC: B06B3/02
Filed: 1974-09-26
Abstract: The vibration generator has a spherical shape with a number of transducers spaced around it, with their centres of action directed into the sphere. The spheres are either hollow, or are elastic balls filled with a hard core. The vibrational energy is concentrated and directed out of the spheres through link rods. Several spheres can be coupled together into an array to provide a directional vibrational force to the working tool. The spheres are vibrated in their normal modes and at set overtones. The separate spheres in the array are selected with different frequencies to generate the desired composite signal. The elastic part of the spheres stores and concentrates the vibrational energy.

Title: Engine with reciprocating piston - turns reciprocating into rotary motion by means of spiral grooves in piston
Inventor: PUCHAS CHRISTIAN
IPC: F01B3/04
Filed: 1974-09-30
Abstract: The engine contains a piston in line with and directly coupled to the output shaft. Guide pins between the piston and the cylinder slide in axial grooves in the cylinder walls. They also fit into grooves which run in sinusoidal spirals round the outside of the piston. The resulting constraint on the piston causes it to rotate as it reciprocates and thus to turn the output shaft. The construction is useful for small engines of low power ratings which it enables to be built compactly and with low weight. The out of balance forces are very small and can be eliminated altogether in a two cylinder engine.

Title: Automatic packaging machine - for frozen fish blocks in plastic foil by endless belts feeding end and side welding beams
Inventor: KRUGMANN ALFRED R
IPC: B65B51/30
Filed: 1974-12-03
Abstract: A block of deep-frozen fish is passed broadside by two endless belts to a stop and, when the latter is released, by a pusher against a curtain of plastic foil, until it is wrapped in on three sides. The fourth is closed by a twin welding mechanism. A cutter blade between the two seams prepares a curtain for the next block. Another pair of endless belts takes the block to a transverse sealing station where two reciprocating welding beams complete the two cross welds half-way up the block. This is a compact installation, suitable for restricted space conditions which can package frozen fish blocks in a vacuum or inert gas atmosphere fully automatically. The machine is easily adjusted for differences in fish block sizes for different countries.

Title: Safety monitor switch for dual braking system - resetting button lifts contacts off ratchets
Inventor: FEIN BERTHOLD
IPC: B60T17/22
Filed: 1974-12-04
Abstract: The safety monitor switch for the dual brake circuit is mounted in a cylindrical metal housing which is screwed into the pressure monitoring valve. The valve operates on a shaft (17) leading into the switch and pushes a connecting bar (16) across two contacts (27) with the bar secured on the contacts via ratchet surfaces. The switch is cancelled by a simple plunger (40) through the baseplate (21) to lift the contact bar off the contacts. The switch does not have to be unscrewed from the brake circuit. The contacts are fitted into the switch simply by pressing the plastic base plate into the metal housing to be secured by tags (34).

Title: Load controlled vehicle brakes - with loading holding off brake control for failsafe operation
Inventor: CORTEY PIERRE
IPC: B60T8/18
Filed: 1975-02-14
Abstract: The vehicle brakes are fitted with a brake pressure control valve in which the piston is subjected to a servo control force proportional to the axle loading. The loading correction is arranged so that with increasing loading the servo force is reduced. This provides a fail-safe operation so that in the absence of any loading signal, i.e. with failure in the loading sensor, the control valve automatically sets the brake pressure correction for a maximum axle loading.

Title: Annular kiln for firing carbon product - with recycling of controlled flue gases portion with cooling air for optimum combustion
Inventor: FISCHER KARL-HEINZ
IPC: C04B35/52
Filed: 1975-05-02
Abstract: Electrodes and carbon bricks are fired in an annular kiln in which a part of the flue gases are purified and recycled in the same direction of flow as the admitted air into the cooling zone of the kiln as flushing gas. The flow rate of the latter is so chosen that the oxygen content of the gas mixt. suffices for an optimum combustion in the firing zone, and that the amount of flue gases provides the required heat transfer to the charge in the preheating zone. This prevents the ignition of the bonding medium vapours in the preheating zone. The optimum combustion in the firing zone is ensured and an adequate heat transfer is provided in the preheating zone. The emission of flue gases into the atmosphere is reduced considerably.

Title: Fuel converted by heat rejected from power generation cycle - produces gas to drive secondary power generation cycle
Inventor: BACHL HERBERT PROF DR ING
IPC: G21D9/00
Filed: 1975-06-20
Abstract: A combination of two thermal power proceses with a fuel conversion process consists of utilising the waste heat of a fairly high temp. primary thermal power process to provide the additional heat demand of the fuel conversion process operating at >=10 bars pressure. The gaseous reaction producs from the conversion process are expanded in a secondary thermal power process, in which the reaction products condense out a different temp. levels and are selectively separated from the remaining gases. In one pref. process the primary power source is a nuclear reactor, supplying e.g. helium at 900-950 degrees C to a turbine where it is cooled to 600-650 degrees C. Fuel is fed into the conversion process and the coke is removed at. More efficient generation of mechanical or electrical power and high-molecular hydrocarbon compoundsd is obtd. The decomposition of the latter is intentionally avoided by using a relatively low temp. in the fuel conversion stage.

Title: Flat notched key for cylinder lock - has inclined notch faces and longitudinal rib preventing its copying
Inventor: KRIESTEN KARL
IPC: E05B19/00
Filed: 1975-10-17
Abstract: The cylinder lock is used for operating with a flat key. The key shank has on its narrow edge locking notches which engage with the tumbler pins when the key is inserted into the lock channel. The key cannot be copied with available key copying machines. The longitudinal central plane of the key channel in the lock is inclined at an angle to the longitudinal plane passing through the axis of the tumbler pins. The locking notch base faces (18) are inclined in transverse direction of the key at acute angle alpha to the key shank longitudinal plane. Hence the distance of the notch base faces (18) from the key back (19) is greater than the corresponding distance to the other key edge F2.
