Patent DE-2332401-A1 (DE)
Title: Automatic lubrication of chain drives - with oil mist lubrication triggered by trip relay action
Inventor: LEBON CORNELIS FRANCISCUS ANTO
IPC: B65G45/08
Filed: 1973-06-26
Abstract: An electrical relay is continuously tripped by the links of a chain drive so as to generate an actuation signal for a solenoid operated three way pneumatic valve operating at line pressure (approximately 6 atmospheres). The valve output drives an intensifier to pressurise the lubricant to 120 atmospheres. A number of lubricant ejector valves are fed from the intensifier and are synchronised with the trip relay actuation so as to emit a lubricant mist on the chain rollers. The lubricant ejectors are spring loaded spool valves with a built in non-return valve stage.

Title: Reverse osmosis to separate tartar from wine - as filtered crystals from cooled osmotic concentrate
Inventor: RHEIN OTTO HEINRICH
IPC: C12H1/02
Filed: 1974-08-12
Abstract: Accelerated crystallisation process in which a solution is passed by a pump to one or more reverse osmosis modules in which a concentrate of super-satd. soln. is separated from a permeate. The concentrate enters a crystalliser to form crystals which are deposited in a filter from which filtrate flows on to be re-united with the permeate. If desired, the crystallisation can be further accelerated by diffusing a fluid of minute bubbles of inert gas, e.g. nitrogen, through the supersatd. soln.; alternatively, the supersatd. soln. can be subjected via immersed electrodes to an alternating current at about 50 to about 200 hertz. Accelerated crystal sepn. from a soln. esp. the removal of tartar as crystals from wine or other tartar-producing drinks. Rapid elimination of tartar in a continuous process which has no adverse effect on the flavour, appearance or other quality of a wine.

Patent DE-2450240-A1 (DE)
Title: Internal combustion engine - with compressor cylinder, reaction chamber for fuel dissociation and expansion cylinder for gaseous fuel ignition
Inventor: HEITLAND HERBERT PROF DR ING
IPC: F02B1/02
Filed: 1974-10-23
Abstract: An internal combustion machine can be operated to produce exhaust gases with lower content or toxic components by compressing a volume of air in a compression cylinder and passing it into a reaction chamber at higher temps. where fuel is continuously introduced and converted by thermal and/or catalystic reaction into dissociated fuel gases. The fuel gas/air mixt. is passed into an expansion cylinder where it is ignited and performs work as it expands. This results in an easy control of the fuel dissociation by adjusting the pressure in the reaction chamber, the temp. or the fuel feed rate. Using a gaseous fuel results in much less toxic components in the exhaust gases, compared with liq. fuel.

Title: Tensionless drawn wax strand for non-bending candles - where tension applied by one drum, is relieved by crosswinding to other
Inventor: BRAND HELMUT DR
IPC: C11C5/02
Filed: 1974-12-03
Abstract: A drawn wax candle strand is produced without inbuilt tension, by passing it during each cycle in which it moves through the molten wax, round the grooved drums in a crosswise run. To accentuate further the bending action in opposite directions, the strand may be made to pass round an additional drum revolving in the opposite direction. Eliminates the compression and stretching taking place in parallel running strand which result in bent candles.

Title: Scissors type lifting table for deep drawing plant - has fast operation but low inertial stresses at motion reversing positions
Inventor: LANG SIEGFRIED
IPC: B29C51/38
Filed: 1975-02-04
Abstract: In a scissors type lifting table for a deep drawing plant with a table platform mobile within two extreme positions a main frame, as well as at least one, pref. double-member, lifting scissors between the main frame and the platform table, the drive of the scissors on its pivot arms takes place via an oscillating crank slot with motor-swung crank. Pref. the scissors drive assembly of motor, transmission gear, crank pivot shaft and crank, is so arranged w.r.t. the scissors and at the same time the effective dia. of the circle of revolution of the crank is selected in such a way that the circle of motion of the effective guide path for the crank slot is tangential to the scissor arms in the two extreme positions of the scissors unit. This meets the requirements for the transport level of the plastic film within the deep drawing plant to be at about the working height for a man when standing, where the use of a trench for the lifting table and its drive is ruled out by the need for universal adjustability, and at the same time ensures a drive system with smooth acceleration and retardation but a rapid overall movement.

Title: Rotary hydraulic machine with concentric rotor - has stator with even number of concave recesses matching rotor ends
IPC: F01B13/02
Filed: 1975-02-12
Abstract: The machine has a rotor (2) mounted centrally in a stator which is in the form of a cylinder with an even number of segmental recesses (11-16) in it. A vane section (3) runs through the centre of the rotor. One end (31) of this has a convex radius equal to the radius of the stator recesses and the other end (32) is formed by two curves each having the same radius as the recesses and leaving a cusp between them. The hub of the rotor (2) is tangential to the smallest diameter of the stator which occurs between the recesses. The length of the vane section is also equal to the smallest stator diameter. The construction enables the vane section to be guided linearly within the hub.

Patent DE-2511018-A1 (DE)
Inventor: KLOTZ HUGO DIPL ING
IPC: B60L1/00
Filed: 1975-03-11
Abstract: The circuit arrangement is intended for an air-conditioning system of a passenger carriage with a power supply from DC or AC voltage systems at the various voltages which are possible with railways of 3000 V DC, 1500 V DC, 1500 V 50 Hz or 1000 V 16 2 DIVIDED 3Hz. It is intended to be easily possible to vary the cooling power of a compressor via the compressor rotation speed without it being necessary to take special precautions to ease commutation in the AC voltage mode. In this case, the system is based on a double-motor drive having two motors (1, 2) which operate on one shaft and are supplied via a main bridge rectifier (7) in the case of DC voltage directly and in the case of AC voltage via an upstream-connected autotransformer (3) and an armature voltage switching device (41, 51, 61). The two motors, which are designed for the mean system voltage of 1500 V, are connected in series or in parallel depending on the voltage value. At the same time, the double-motor drive (1, 2) is connected to a field-weakening switching device (101, 111) in the case of a DC voltage supply and to the armature voltage switching device (41, 51, 61) in the case of AC voltage supply in order to achieve the desired stepped rotation speed adjustment. In consequence, taps (4, 5) and one of the winding ends (6) of the autotransformer (3) can be connected to the main bridge rectifier (7), an additional auxiliary bridge rectifier (8), which is connected to the highest voltage stage (6) of the autotransformer (3), being connected to the shunt-wound field winding (9) of the coupled motors (1, 2). <IMAGE>
Patent DE-2511020-A1 (DE)
Title: Accelerator and brake pedal mechanism for motor vehicles - has electromagnetic interlock system to speed brake application
Inventor: TEETZ GUENTER
IPC: B60T7/06
Filed: 1975-03-11
Abstract: The brake pedal and the brake are kept in the off position by a resistance determined by the normal off pressure of the foot. For safety reasons the resistance can be a little more than the off pressure. The holding force is prematurely released if the gas pedal is quickly moved up, at least by the time the idling position is reached. The mechanism on the brake pedal consists of an electromagnet (1) and a ferro magnetic counter plate (2) fixed to the brake pedal. The operation of this electromagnetic system follows the position of the gas pedal (5) automatically. The holding force is adjusted by a potentiometer. An extension to the principle has a hydraulic system with throttle to transmit the pedal force and the design can also be adapted for use with radar distance warning systems and automatic transmissions.
