Patent DE-2428890-A1 (DE)
Title: Heated or cooled roll - with contact-free power supply and measuring signal output, e.g. for use in textile or film drawing
Inventor: GUNTERMANN REINHARD
IPC: G05D23/24
Filed: 1974-06-14
Abstract: In a heated or cooled roller, e.g. a draw roll for textile yarn, films, etc., having at least one temp. measuring element, esp. a temp.-sensitive resistance, torating with it as well as an active measuring signal transducer esp. an RC-oscillator mounted on a co-rotating system, the current supply part of the measuring signal transducer is provided with a rectifier the input of which is coupled to the output of a stationary high frequency generator via a condenser consisting of one fixed plate and one plate rotating with the roller. In contrast to known systems the temp. is sensed directly and the use of integrated components gives simple reliable, and less costly system of relatively high precision. Since the power is supplied by a contacless system, maintenance is low and mechanical failures are largely eliminated.

Title: Centrally controlled telephone PBX - has group relays each serving group of terminals for call transmission
Inventor: PATTYN JEAN-LUC
IPC: H04M3/54
Filed: 1974-08-14
Abstract: The centrally controlled private branch telephone exchange has mutually authorised terminals grouped together for the mutual acceptance of conversations. With each group is associated a group relay. When a terminal in one group calls, the contacts (3c, 4z) denoting that terminal are connected over an evaluator to the group relay belonging to the respective group. Only when a non-interrogated call appears, belonging to the same group of terminals and the respective terminal does not answer, the switching elements are connected and switch the call to an answering terminal. The call starting switches are preferably connected via a group relay contact, a multiplex circuit, the non-answering terminal line and the switched through current path.

Title: Hardwearing non-slip rubber elastic stud for portable appliances - has supporting sole with recess surrounding protruding compressible non-slip element
Inventor: OESTREICH DIETER DR ING
IPC: A47B91/04
Filed: 1974-08-21
Abstract: The rubber-elastic stud feet for portable appliances such as telephones, kitchen machines etc., comprises a supporting layer which is divided into at least two supporting elements and at least one anti-slip element (1.4) which is mounted spaced from but in between the two supporting elements and is dimensioned so that when in the relaxed state it protrudes beyond the sole of the stud determined by the first elements. When loaded, the non-slip element (1.4) is compressed into the recess (1, 3) and shortened and when the stud is moved relative to the tabletop it is bent sideways and rests with its head against the side of the ajoining supporting element, thereby acting as a non-slip support. The sides of the surrounding supporting element defining the recess are preferably provided with a shoulder for the head of the protruding element to increase the wedging effect.

Title: Oil fired hot water boiler - fitted with servo operated valve to reduce wastage of residual heat
Inventor: WEBER EGON
IPC: F24H9/20
Filed: 1975-02-19
Abstract: A butterfly valve or slide valve is fitted to the uptake pipe leading from the boiler to the chimney. The valve (1) is operated by servo motor (2), connected to the control system for the burner in such a way that the first ignition impulse also initiates opening of the valve, and that the valve is closed when the burner is shut down. By this means, dissipation of residual heat into the chimney will be substantially slowed down, causing more of the heat to be transferred into the water.

Title: Controller for magnetic stripe tags processing stations - photo-sensors starting station depends on distance and transport speed
Inventor: LAGOE DUNCAN JOSEPH
IPC: G06K1/12
Filed: 1975-07-10
Abstract: The invention provides a control arrangement to optimise the operation of individual processing stations for article cards or tags which contain magnetisable stripes, as well as print areas. The arrangement has photosensitive sensors in the card path before the processing stations directed at the middle area of the stripes. The sensors are triggered by the front edges of the magnetisable stripes of each card, the stripes being separated from one another by gaps. Depending on the speed of transport indicated by an impulse emitter and the distance to the processing station, the station is started by the sensor through a delay counter.

Patent DE-2600121-A1 (DE)
Inventor: ZISTERER PETER
IPC: A63C11/02
Filed: 1976-01-03
Abstract: The ski rack has holding bars (3) assigned in each case to one ski or a pair of skis (10) and attached to a fixed base body (2). The ski rack serves for the orderly storage of the skis or pairs of skis in a substantially vertical direction, for example in a storage room. The holding bars (3) are linked in each case to the base body (2) in the horizontal direction and, in the position of use, engage around the skis or the pairs of skis on one side and have an inner and an outer holding limb (5, 6) running parallel or approximately parallel to the linkage axle (7). Said holding limbs bound a cross-sectional area (11) of the bar whose projection into the horizontal plane varies when the holding bar (3) is pivoted. The holding bar (3) can thus be pivoted downwards in the position of use to the extent that the two holding limbs (5, 6) support the skis or pairs of skis hanging freely by frictional force with the ends of the skis arranged below the holding bar (3) bearing against a counter-surface. <IMAGE>

Title: Vehicle self locking differential - has additional freely rotating shaft providing viscous drag if relative torques on half shafts are different
Inventor: STAUDENMAIER GERHARD
IPC: F16H48/20
Filed: 1976-03-06
Abstract: The self locking differential incorporates an additional freely rotating shaft which provides viscous drag if the relative torques on the two half shafts are different. The additional element transfers torque from one shaft to the other so that both wheels tend to lock together. The system operates without any mechanical friction which would lead to wear and imbalance. The system also enables large torque transfers to be achieved at low axle speeds and low transfers at high speeds, i.e. when travelling. This system operates for traction as well as braking so that a measure of anti-skid control is obtained for the rear wheels.

Title: Fabric measurement appts. - has a section where fabric forms a loop for sensor to control fabric advance when working with a stretch material
Inventor: PABST MANFRED DIPL ING
IPC: D06H3/00
Filed: 1976-05-20
Abstract: Appts. for measuring the length of moving fabric piece goods has sensor which accommodates to the strength of the fabric before the material passes through a looped section between two rollers. The sensor triggers control units to determine the loop of fabric to give the least amount of stretch to the material and to ensure that it follows a straight path between the rollers. The system allows fabrics with a high stretch potential, such as knit goods, to be measured accurately and to follow a straight path as they move through.

Title: Magnetic flaw detector for conducting materials - uses phase comparison between exciter and detector coils to locate discontinuities
Inventor: FOERSTER FRIEDRICH DR PHIL
IPC: G01M99/00
Filed: 1976-09-17
Abstract: The magnetic flaw detector for determining discontinuities in materials, esp. electrically conducting materials, is suitable for continuous measurements on pipelines for example. The detector comprises a frequency generator (53) which feeds an induction coil (57) placed on the upper surface of the material (1). Two identical pick-up coils connected in opposition (73) are connected to an analyser (77) and to a pre-amplifier (61) in a differential mode. The output of the pre-amplifier feeds a phase-sensitive rectifier (63) whose amplified output is fed back to the generator to control its frequency. A phase-shift network (67) is connected between the rectifier and the exciter coil. The phase difference between the excitation and detected fields is maintained constant irrespective of the thickness and electrical conductivity of the material under test.
