Patent DE-2121391-A1 (DE)
Title: Producing non woven resilient fabric
IPC: D04H3/00
Filed: 1971-04-30
Abstract: In the production of a non woven fabric web, a band of crimped, continuous filament tow of polyethylene terephthalate or cellulose acetate is drawn from a bale and passed over a banding roller which generally straightens the tow and removes any snags or false twists. The band of tow is then passed through a spreading zone comprising a number of gripping rollers, one roller of each pair being rubber and its mating roller having alternating lands or grooves which provide an intermittent and differential gripping action on the crimped filaments. The action of these rollers causes the crimps to deregister and separate, prior to entering spreader units. The original tow is spread in stages to entering spreader units. The original tow is spread in stages to a web of between two and ten times its starting width and having a substance of under one ounce per square yard. In this condition the web is delivered on to surface of an endless belt to be passed through a bonding agent applicator followed by a heater dryer section, which unifies and dimensionally stabilizes the spread web. Zig-zag stitching may be used to obtain dimensional stability as an alternative to a bonding agent.

Patent DE-2345019-A1 (DE)
Title: Self aligning bearing for motor spindle - resilient spherical body clamped between two bearing shells
Inventor: RETZLAFF WALTER
IPC: F16C23/04
Filed: 1973-09-06
Abstract: In prior designs the self aligning of the bearing was achieved by application of gripping eyelets acting in axial direction against one side of the spherical bearing body, and care had to be taken that the gripping moment of the eyelet should be appropriate to the force necessary to shift the bearing during self aligning action. The present design takes care of this relation automatically by using the two shell arrangement and an elastic adjustable gripping ring acts on a groove on the second shell which is divided into three segments by radially orientated gaps.

Title: Rotating element testing method - tests for irregularity of dimensions when element is slowly rotated about its axis
Inventor: BEYER RUDOLF
IPC: G01B7/28
Filed: 1973-10-30
Abstract: The element axis is held immobile in space, and its surface is tested point-by-point by a feeler movable in a coordinate direction parallel to or perpendicular to the axis of rotation. When the element rotates, the feeler is moved along a nominal reference line near the tested surface, and changes in the distance between the reference line and the tested surface are measured. The nominal reference line is continuously precalculated point-by-point in accordance with the element rotation, and the separately driven feeler is guided by a follower control device. The element rotation is differentially measured in the form of a first pulse train, and the feeler linear motion is similarly measured by a second pulse train. The feeler is guided in accordance with the comparison result of the two trains.

Title: Injector needle for meat preservation - having double acting valve to allow recycle of brine
Inventor: BACHERT ARTHUR
IPC: A23B4/28
Filed: 1974-01-29
Abstract: Valve for use with injector needle for meat pickling or preservation has an outlet port, a sliding valve arrangement operated by a lever, a pressurised supply of pickling brine or preservative soln., and a recycle port. (I) is normally closed by action of a spring and the brine flows in via a port and recycles from another port. (II). When a lever is depressed, brine is ejected from (I) to the needle and is progressively closed. The valve slide has its motion limited by stops. The recycle line is of the same cross section as the feed. The slide has two gates which can completely seal branches. During the preservation of meat by pickling with suitable brine, the brine is injected into the meat under pressure at pulses of short duration. If the pump is subjected to repeated pulses, it becomes damaged. To overcome this problem, the recycle is provided which means that the pump has a continuous throughput, esp. helpful on centrifugal pumps. Also with certain brines deposits can occur and solid crystals from in the soln. if evaporation has occurred. These cause abrasion and damage to the valve but if a continuous recycle is maintained this is reduced because the valve is continuously flushed. There is also less chance of breaking the needle. Normally it should be flushed out after use. Similarly the pump impellor can be damaged by crystals so by keeping the soln. moving this can also be avoided.

Title: Lamp operation with low intensity DC current - source voltage is higher than necessary for lamp operation
Inventor: HERRMANN WALTER
IPC: H05B39/09
Filed: 1974-04-26
Abstract: The arrangement is designed to supply lamps with a d.c. of lower rating yet higher voltage than is necessary for the working of a lamp. Preferably an electronic switch is used to chop the d.c. current and is in series with a self-inductance which charges a capacitor through a diode with the disconnection pulses so generated. The capacitor is continuously discharged through the lamp. The self-inductance is an isolating transformer in whose output winding the voltage surges appear when the circuit is broken. Such an arrangement can be used in an emergency kiosk which cannot be connected to the mains or other energy source requiring servicing, thereby only leaving the telephone lines themselves as the means of power supply.
