Filed: 1975-12-29
Abstract: 1502510 Cathode-ray tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 Dec 1975 [11 Dec 1975] 52975/75 Heading H1D In a cathode-ray display tube in which an electrode-e.g. the shadow mask of a colour television tube-makes spring contact with a conductive layer on the envelope wall 1, sparking at the contact, due to the protrusion through the coating of glass projections arising from the roughness of the glass surface, is pre vented by ensuring that, beneath the area of contact of the spring 6, the surface roughness of the glass is at least 25% smaller than the thickness of the layer. The remainder of the envelope surface is left with its normal roughness to facilitate adhesion of the conductive layer. The reduction of roughness is produced by polishing the glass, or by smoothing the relevant area of the die employed in manufacturing the envelope.

A weft machine, which may be circular, is provided with one or more of warp knitting units so that interknitted weft and warp fabrics, or adjoining integral weft and warp fabrics may be knitted. The units may be situated at either or both ends of the weft machine bed or beds or intermediate their ends. In one embodiment each warp unit comprises a series of needles U-Z mounted in a bed, and a series of yarn guides A-G in a block 7. The needle bed is reciprocated by means of a pin 100 engaging a slot 101 in cam 1. A cam follower 6 controls lateral movement of the yarn guides via linkage 5, 18, and the guides are swung between the needles by a pivoted lever 9 controlled by a cam follower 8. The cam is swung anticlockwise and returned to the neutral position during a first stitch forming cycle, and then in the opposite direction so that the guides wrap different needles on the next course. On alternate courses warp yarn is wrapped by guide A around the end weft needle 13. The unit is movable across the beds so that borders may be knitted on fashioned blanks. In a modification for knitting warp fabric intermediate the ends of the weft fabric the warp yarn guide controls pass above the weft yarn guide track. The warp fabric may be joined at either, or both edges to, or interknitted throughout with the weft fabric. This is achieved by wrapping the weft needles adjacent the edge warp needles with warp yarn from the outer warp yarn guides, or by laying in the weft across the warp needle bed, or bath.

Abstract: 1371109 Automatic tension control BELL & HOWELL CO 23 Nov 1971 [15 April 1971] 54264/71 Heading G3R In apparatus using information recording tape located in a tape containing means, tape is withdrawn from the tape containing means, formed into a loop and placed in driving engagement with a capstan, the tension in the tape loop being retroactively controlled. In an embodiment, tension of magnetic tape from a cassette is equalized on both sides of a capstan by a closed-loop tension control for each side which control motors driving respective tape spools. The tension in tape portion 33 on one side of capstan 24 is measured by feeler 60 to provide an actual tension signal from strain gauges 61, 62, which is compared in an operational amplifier 43 with a tension reference from a potentiometer 54, that is across a regulated supply 55, to provide a tension error signal which controls motor 71, driving spool 20, through a power amplifier 68 which includes transistors 73, 78. The closed loop bandwidth and stability are increased by an integrating capacitor 210 across amplifier 43, by providing a bias signal to the power amplifier via switch 96 and variable resistor 98, and by capacitor 93 and RC network 94 in the power amplifier 68, which includes a speed feedback path 91. To reduce tension in the tape whilst it is withdrawn from, or returned to, the cassette 13 i.e. when the control system is open loop, a switch 89 opens to add resistance 300 to the spool drive motor circuit. This motor is stopped by closing switch 92, thus grounding the input to the power amplifier. The tension in tape portion 34 is similarly controlled through amplifier 48, power amplifier 168 and motor 171. Motors 71, 171 and capstan motor 24, which is controlled through variable resistor 201 and reversing switch 200, may be of permanent magnet type. The tape may be withdrawn from, or replaced into, the cassette, and positioned around capstan 24 by apparatus as disclosed in Specification 1370156

A positive action rotary clutch particularly suitable for use in high-speed office machinery comprises a driving member 2 having a driving element 12 which continuously drives a clutchengaging member 11. A clutch-actuating rod 10 is secured to the member 11 and passes through bores 8, 9 in the driving member 2 and in a gear 3. Dogs 6 on one face of the gear 3 may engage the member 11 and drive is then transmitted to an output gear 4. The other face of the gear 3 has dogs 7 which may be engaged by a brake 13 axially movable with the rod 10. The rod also carries an armature 15 of an electromagnet 16. A cam 18 is continuously driven with the driving member 2 and the rod 10 is biased to the left by a spring 17. The cam rotates at the same speed as the member 2 and engages the rod 10 with maximum lift when the plane through the dogs 6 and the rod is substantially at right angles to the longitudinal axial plane of the member 11. If the magnet is energized at this point of lift the rod 10 is held against return, the member continues to rotate until it engages the dogs 6 and the gears 3, 4 are driven. To disengage the drive, the magnet is de-energized and, as the cam 18 passes the maximum lift position, the brake arms 13A move into the path of the dogs 7. With the cam now in its minimum lift position, the member 11 moves clear of the dogs 6. Although the member 11 moves axially into the path of the dogs 6 during each revolution there is no engagement due to the relative rotational positions of the dogs 6 and the member. In place of the cam 18, a cam secured to the housing 1, by co-operating with a detent on the member 11, causes one forward-and-return movement of the rod 10 for every revolution of the driving member 2.
