Title: Elastic-stocking knitting machine with electronic control device - operating variable-speed yarn feed and control drum motors
Inventor: LUCAS HARRY
IPC: D04B15/50
Filed: 1980-01-23
Abstract: A circular knitting machine for the prodn. of elastic stockings, having a positive-feed device for at least one elastic yarn and a pawl-and-ratchet-operated control drum, has a computer-controlled drive mechanism which regulates the speed of the positive-feed device and the movement of the control drum in relation to the speed of the revolving cylinder. The computer receives input signals from a revolution-counter monitoring the knitting cylinder, and outputs synchronised control signals to at least one step motor driving the feed device and the control drum according to a pre-programmed relation. This arrangement replaces a proportion of the complicated mechanical controls with a simplified electronic system, which can be added to existing machines without requiring substantial machine modifications.

Title: Correctable ink decolourised by alkaline eradicator - contains weak acid or acid salt forming buffer with eradicator on writing over correction
Inventor: MECKE NORBERT DIPL CHEM DR
IPC: C09D11/16
Filed: 1980-05-08
Abstract: Chemically correctible ink for writing-erasure systems is acidic and contains dyestuffs (I) decolourised by an alkaline ink eradicator. Improvement is that the ink contains an additive of 0.1-10 (0.5-5) wt.% weak acid or acidic salt with a pKa value of over 0, which forms a weakly acidic buffer mixt. on the paper with the alkaline constituents of the eradicator. The systems can be used in fibre-tipped pens. On writing over the corrected area, the buffer inhibits the eradicator.
Patent DE-3024493-A1 (DE)
Title: Controlling addn. of gas or liq. to drink - by balancing double system responsive to property changes
Inventor: WIELAND DIETER DIPL ING
IPC: B01F3/04
Filed: 1980-06-28
Abstract: The addn. of a gas and/or liq. component into a second liq. for making drinks is controlled by initially measuring a physical and/or chemical property of one component, deriving a standard amt. of added component, and controlling the component feed adjuster by a first system responsive to the standard amt. and an instantaneous index value. The property concerned is measured in the mixt. and the actual value is compared with an index value by a second control system. When a permitted deviation is exceeded, a corrective signal alters the instantaneous index value at specified intervals. The first control system supplies the second control system with a signal indicating the change in the feed adjuster and which is compared with the deviation from the index value and ceases to activate the feed adjuster when a predetermined change is reached therein. The appts. is also claimed. Used for adding CO2 with a concentrate to mineral waters, etc., and produces a standard mixt. without hunting of the controls. The coarse forward regulation is refined by the periodic reverse regulation.

Title: Inductive rotation speed and direction sensor - has passive integration capacitor terminating transfer channel suppressing external noise, channel capacitance
Inventor: BAJORAT KLAUS ING GRAD
IPC: G01P13/04
Filed: 1980-12-02
Abstract: An inductive revolution rate and rotation direction transducer is maintenance free, robust and has a high degree of angular resolution. It can operate at temperatures up to 200 degrees without loss of performance. Each phase voltage produced by a permanently stimulated multiple pole a.c. generator with n-phase stator windings is passively integrated and fed to an electronic evaluation device via a transfer channel. The transfer channel is terminated on both sides by a half of the integrating capacitor. The above arrangement excludes the effects of external noise sources and channel capacitance. The evaluation unit rectifies the integrated phase voltage, amplifies it and feeds it via a bandpass filter to a trigger which determines the null points of the phase. The trigger element outputs are input to an OR gate common to all evaluation units.

Patent DE-3047875-A1 (DE)
Inventor: KISS LORANT
IPC: D06F67/02
Filed: 1980-12-18
Abstract: The drying cylinder (1) of the equipment has mutually parallel channels (4) underneath its surface. At the two ends of the cylinder, both inlet branches (5) and outlet branches (11) for a heat transfer medium are provided. The individual channels (4) are connected to the inlet and outlet branches (5, 11) in such a way that the heat transfer medium flows in opposite directions in each pair of adjacent channels. The channels are either unchanged in cross-section, or their cross-section decreases, so that the flow is accelerated. The heat transfer medium used is a combustion product which is mixed with air. The result of using the equipment is that, in spite of the relatively thin dimension of the cylinder wall, the surface of the drying cylinder (1) has a uniform temperature. <IMAGE>

Patent DE-3134785-A1 (DE)
Title: Sealing ring, in particular a piston ring
Inventor: HELLER RUDOLF
IPC: F16J15/3268
Filed: 1981-09-02
Abstract: On a sealing ring for mounting on a piston plate, a clamping collar projects at an angle from a sealing lip of the sealing ring, the collar engaging under elastic stress on that side of the plate which can be subjected to pressure medium. Engaging on the opposite side of the piston plate, which can be produced as a simple punched part, is a projection of the sealing ring, the piston plate thus being grasped pincer-fashion. In the case of piston plates which can be pressurised from both sides, a second, essentially identical clamping collar acting under stress is provided instead of the projection. <IMAGE>
Patent DE-3141059-A1 (DE)
Inventor: POLLOK HANS-JUERGEN DIPL ING
IPC: F16C33/10
Filed: 1981-10-13
Abstract: A self-pumping thrust bearing for electric machines having a vertical shaft is disclosed in which oil circulates through radially-extending bores in a rotating thrust ring to suck hot oil from an oil space and transfer it to a ring canal disposed in a stationary part. In order to make the transition from the rotating thrust ring to the stationary ring canal as loss free as possible, there is arranged on the outside at the thrust ring a circular canal into which the bores lead. This circular canal is bounded on the side facing the stationary part by a height-adjustable ring which is held at the thrust ring with a gap between the ring and the thrust ring. The transfer of oil therefore takes place around the entire circumference of the thrust ring so that turbulence is avoided. The quantity of oil pumped can be adjusted by adjusting the width of the gap.
Patent DE-3151231-A1 (DE)
Title: Vehicle tyre with variable road adherence
Inventor: SCHULTE GERD
IPC: B60C11/16
Filed: 1981-12-21
Abstract: In contrast with other proposals, which usually appear too complicated, relating to pneumatic vehicle tyres with spike properties, the tyre structure according to the invention simultaneously ensures maximum safety and protects the road because of the road adhesion which is variable as a function of speed, which is achieved by virtue of the fact that the tread is composed of a plurality of circumferential rings (2, 3, 4) of differing diameter which are adjacent to one another, the, preferably central, tread ring (2) which is kept inherently stable by means of fabric or metal inlay belts (5) having a larger diameter than the lateral tread areas (3, 4) of a conventional type and being clamped in a radially soft manner by means of beads (6, 7) on both sides and a cavity (8) which is located below them and is also circumferential and being adjustable in respect of its resilience by means of dividing chambers installed in the cavity and having intermediate valves. The lateral tread areas (3, 4) provided for example with spikes contribute at a low speed of revolution of the wheel to the road adherence to a maximum degree but in the case of more rapid travel lift off automatically; these are therefore genuine multi-purpose tyres. <IMAGE>

The cavity (16) is filled with a fluid. Damping is effected by the fact that the taper (13) is driven into the bore (12). During this process, the cross-section of the annular gap (21) according to Fig. 2 decreases continuously. <IMAGE>
