Title: Loop pile carpets
Inventor: WITTAUER SIEGFRIED
IPC: D03D27/00
Filed: 1964-10-05
Abstract: Yarn of uniform denier, intended to form loops of uniform height in the pile of multicoloured woven or tufted carpets, is formed by plying two or more single end components, e.g. bulky, multifilamentary, nylon yarns, of different colours or shades thereof, at least one of which is fed non-uniformly, e.g. through a cam-operated traversing guide, to the twister.  The number of turns per unit length of ply twist of at least one component varies in random fashion such that there is a minimum deviation from the average number of turns per unit length of ply twist of that component of at least 10% in a multitude of sections along the length of the plied yarn.

Abstract: 1313888 Position encoders LEM INSTRUMENT CORP 26 Aug 1970 [2 Oct 1969] 40998/70 Heading G4H A position encoder for a shaft 16, &c. comprises a number of electrically energizable position indicating segments 52, an inverter 18 for applying electric signals to the segments and a diode matrix 20 connected to the segments for providing electric signals corresponding to the position of the shaft. The segments 52 form a conductive track on the encoder disc 12 which is made of plastics and is provided with a second track 32 formed of conductive elements 34 and non-conductive spaces 36. A brush assembly 14 rotates with the shaft 16 and includes brushes 72, 82, 84. The track 32 is energized by a source 41 and the brush 72 is connected via a further brush 78 to the input of the inverter. As the brush assembly rotates the inverter alternately applies signals on its output leads 98, 100 to the brushes 82, 84 via further brushes 94, 96. The control of the signals on the brushes 82, 84 by the signal on the brush 72 enables the eighteen segments 52 to provide a ten degree resolution for the encoder. In a modification the inverter is replaced by solenoid operated switch contacts. An encoder having outputs for the sine of the angular position of the shaft, the quadrant and sign is also described and a pair of encoder discs having their brush assemblies connected by gearing to enable position counts for a number of revolutions of the shaft is described. The tracks on the encoder disc may co-operate with magnetic sensors.

As illustrated, the shaping is effected by supplying a compressed fluid, e.g. air, via port 50 and simultaneous approach of annular supports 4, 9. The member 34 may be secured to support 9 (as illustrated) for movement therewith, or may be rotatable and axially movable relative to that support. The member 33 is rotatable and axially movable relative to the support 4. Flexible   diaphragm 5 is optional, and annular springs 21, 32, when radially expanded by outward axial movement of annular members 10, 22 relative to the supports due to supply of, e.g. air to spaces X, assist in clamping the beads and prevent their movement relative to the supports. Instead of the springs, the diaphragm may be suitably reinforced adjacent the supports. Tread and breaker supporting elements 37, 38 (or 51, 52, Fig. 7, not shown) integral with, or separate from (Fig. 7), the members 33, 34 may be provided. The carcass may be expanded by expansible rigid sectors instead of by inflation pressure as illustrated. The carcass may be built up on the apparatus.

Title: Television signal blanking
IPC: H04N5/16
Filed: 1971-09-08
Abstract: 1306667 Video blanking circuit ROBERT BOSCH FERNSEHANLAGEN GmbH 8 Sept 1971 [8 Sept 1970] 41905/71 Headings H3T and H4F A method of blanking a television video signal comprises using an emitter coupled pair of transistors 2, 3 as a current switch to pass or blank current from a direct current source, modulated with the video signal, to an output. One transistor of the current switch has a reference potential on its base and the other has a blanking signal applied thereto. Transistor 1 may function as the current source modulated by video signals Á. A blanking signal at A causes the transistor 3 to cut off and the output is clamped at supply potential. By using a second pair of transistors 2<SP>1</SP>, 3<SP>1</SP> with a transistor 1<SP>1</SP> or resistor current source 1<SP>1</SP>, which remains constant when set, and a differential amplifier 6, the blanking level lies at the zero crossing points of the signal. If the current through 1<SP>1</SP> is adjusted by preset resistance of 500 # the blanking level is adjusted. The 5K # resistance to the base of transistor 1 may be replaced by a further transistor (7, Fig. 3a, not shown) which is driven by clamping pulses to clamp the video signal to a reference level.
