Patent DE-2333561-A1 (DE)
Title: Oscillating hypocycloidal gear drive - has internally toothed wheel attached to piston to produce linear oscillating motion
Inventor: HALLER ERNST GEORG
IPC: F16H21/36
Filed: 1973-07-02
Abstract: With hypocycloidal gears, if the pinion pitch circle diameter is half the diameter of the internally toothed gear wheel, then a point on the circumference of the pinion will describe a straight line which is a diameter of the larger gear. The invention uses this principle in a manner different from existing applications by rotating the pinion about a point on its circumference and making the internally toothed wheel a part of the piston. The idea can be further developed by the use of additional gears meshing with both the pinion and internal gear.

Title: Double path rectifier for respiration signals - has gain adjustment control for amplification of positive and negative fractions
Inventor: BECKERT GERHARD
IPC: A61B5/087
Filed: 1973-07-02
Abstract: Double path rectifier for electrical respiration signals has a valve and amplifier arrangement to detect solely the positive or negative fractions in the electrical signal, respectively amplified by a factor or 2. A superposer is for the corresponding fractions in the original, synchronously superposed. The amplifier has an adjuster for the gain to values different from the factor of 2. Preferably when the smaller positive or negative fraction is detected and amplified, the adjuster is constructed solely to adjust the amplification gain to higher values than 2. An operational amplifier is used; at least one of the feedback and signal coupling resistors is variable and forms the adjuster for the gain. Disturbance in the summed signal, which is of diagnostic use, are eliminated.

Title: Variable axial piston hydraulic transmission - has primary and secondary pump and motor pistons from coaxial input and output shafts
Inventor: NEUKIRCH JOHANNES
IPC: F16H39/10
Filed: 1973-07-04
Abstract: This hydraulic transmission has co-axial input and output shafts and consists of two cylinders that contain the spring-loaded hydraulic pistons. The primary cylinder that is driven by the input shaft is the pump, the second cylinder with its pistons surrounds the pump cylinder and forms the hydraulic motor.

The swashplate angle of the pump can be varried and with it the angle of motor section swashplate. The balanced hydraulic circuit prevents excessive loading on bearings, control cones and other highly stressed parts.

Title: Turbogenerator stator packet - has eddy current losses reduced by displaced slots cut into sides of packets teeth
Inventor: FRITZ WERNER DR-ING
IPC: H02K1/16
Filed: 1973-10-24
Abstract: The stator packet, for turbogenerators, has slots cut into the sides of its teeth to reduce eddy current losses. The slots extend into the teeth a distance approx. equal to 1/4 of the tooth's width. The slots on opposite sides of a tooth are displaced w.r.t. one another so that they do not coincide. This choice of positioning and length of slot does not significantly weaken the stator packet's teeth. These transverse slots may be used alone or in conjunction with the more usual longitudinal slots set down into the teeth parallel to their axes.

Title: Mfg concrete reinforcing rods - stock material sprayed with oil emulsion before drawing
Inventor: HUFNAGL WALTER DIPL ING
IPC: B21B45/02
Filed: 1973-12-13
Abstract: The wire from which the reinforcing rods are made is unwound from the spool, straightened out and drawn or reduced in diameter by any conventional method such as rolling, to give it a profile. Before the material is passed through the drawing die or the roll, it is sprayed with a water-oil emulsion. The spraying process is carried out before each drawing or rolling stage. The emulsion consists of 5 to 25% oil and 95 to 75% water. The oil used has a low viscosity. The use of the oil emulsion improves the throughput and reduces wear on the work rolls or dies etc.

Title: Stirling heat pump for heating unit - has piston sealed with flexible welded metal bellows, with regenerative heat exchange
Inventor: RAETZ KARLHEINZ DIPL PHYS
IPC: F25B9/14
Filed: 1974-01-04
Abstract: Heat pump has a piston sealed with a flexible, welded metal bellows, adiabatic losses on which are prevented by regenerative heat exchange. The regenerator consists of metal foil strips, which are wound from alternately smooth and edged foils. More particularly the largest volume can be attained with high gas pressure, the metal bellows is vacuum tight, and H2, as the ideal working gas, can be used. Frictional losses at the piston are eliminated. The additional spring force required for compression of the gas is recovered on expansion. Metal bellows can be produced of hysteresis free alloys.

Title: Multi feed rear view mirror - with central, horizontal section for through viewing for added safety
IPC: B60R1/08
Filed: 1974-07-29
Abstract: The interior rear view mirror is divided into separate horizontal sections. The middle section has no mirror surface, and coincides with a gap in the mirror housing. The driver is able to look through the mirror to see traffic lights and signs, and pedestrians, without having to move his head, and without losing the advantage of a rear view. At night the central section greatly reduces glare from following vehicles. The remaining mirror surfaces can be plane or curved and can also be separately pivoted for individual adjustment to cover blind spots etc.
Patent DE-2437895-A1 (DE)
Title: Epitaxial growth from liq. phase - by contacting melt and substrate prior to heating jointly to high temps
Inventor: WEYRICH CLAUS DR
IPC: C30B19/12
Filed: 1974-08-06
Abstract: An epitaxial layer is grown on a substrate by bringing the matl. of the melt in contact with the substrate at a low temp. and by heating them jointly to a high temp. This dissolves some matl. of the substrate in the melt which is later deposited as epitaxial layer on the substrae when the temp. drops. The melt film thickness is held between a specified upper and lower limit. This process saves the awkward tipping operation of the melt at max. temp; and the whole substrate surface is covered by the melt and protected against atmospheric attack. The epilayer can be procured with an excellent uniform thickness.

Title: Dehydrated potato prod. prepn. - using differential speed pressing drums to peel cooked potatoes
Inventor: WESTOVER JACK D
IPC: A23L19/12
Filed: 1975-01-09
Abstract: Pieces of cooked unpeeled potato are placed between a pair of apertured cylindrical pressing drums which are rotated at different speeds to provide a shearing action which severs the ligaments of edible potato that extend through the openings in the drums from the adjacent peelings, to force cooked edible portions of the potato through the apertures in the drum leaving the peeling on the surface of the drum. The mashed potato is then dried to give a non pasty dehydrated potato, in higher yield and better flavour.
