Title: Tape lifter
IPC: G11B15/61
Filed: 1969-06-20
Abstract: 1,255,727. Recording and playback. RCA CORPORATION. 20 June, 1969 [24 June, 1968], No.31337/69. Heading G5R. A web supporting and lifting arrangement, particularly for enabling a recording tape to be lifted from a rotating recording head in a video recording system during a non-recording mode, to minimize wear, comprises a member with a web support surface and a number of holes communicating with and inclined to the surface with a plunger slidable in each hole. An actuator movable parallel to the surface cooperates with the plungers so as to be able to cause or permit them to move into or out of engagement with a supported web to lift it from or lower it to the surface. The support surface may be a fixed mandrel 8 in which is mounted a rotating head wheel 11, the tape 14 overlying the mandrel and the heads. Flexible rods 16 are supported in holes 15 in the mandrel. Upward movement of the actuator 18 pushes the rods through the holes to lift the tape away from the rotating head. In an alternative arrangement (Fig. 5, not shown), the tape is supported by a rotating mandrel in which heads are mounted. Rigid rods pass through holes in the mandrel and bear internally on the surface of a shaped actuator, which may but need not rotate with the mandrel. U-shaped pieces may be used instead of rods in either embodiment. The wrap of the tape may be normal to the mandrel axis (Fig. 1) or skewed (Fig. 5). The relation between tape and heads may also be orthoganol, as in a quadruplex recording system.

Filed: 1966-07-13
Abstract: 1,188,287. Pneumatic tyres. DUNLOP CO. Ltd. 12 July, 1967 [13 July, 1966], No. 31372/66. Heading B7C. A pneumatic tyre has a tread portion 1 provided with ribs or blocks 2 and a shoulder portion provided with protuberances 6, the resistance of which to deflection under a given load per unit area is substantially less than that offered by a corresponding adjacent unit area of the tread portion under the same load whereby when a load is applied to the shoulder portion as the tyre rolls along the road surface to ride over an edge formed on the road surface disposed at a slight inclination to the direction of rotation of the tyre, the protuberances are compressed or deflected by the load applied by the edge gradually to transfer the edge load to the main load-carrying tread area of the tyre as the tyre is steered over the edge. The protuberances may be circular, elliptical, or polygonal in crosssection and uniformly spaced apart. The area covered by the protuberances may extend in height to 1/6 of the height of the tyre measured from the edge of the tread to the bead base radially around the tyre section curvature. The shoulder portion may be provided with a stepped shoulder portion 3, or a rounded or angled shoulder portion, near the tread edge.

Title: Vertical deflection current stabilization in colour television receivers
Inventor: HALL C J
IPC: H04N3/16
Filed: 1971-07-05
Abstract: 1393249 Cathode-ray tube circuits RCA CORPORATION 30 June 1972 [5 July 1971] 31463/71 Heading H4T [Also in Division G3] A feedback control system for the vertical deflection current in a colour television receiver includes an arrangement for eliminating the effects of variations in the current in a parallelconnected convergence circuit. As shown in Fig. 2, a vertical deflection winding 12, which may be connected in series with a temperature compensating thermistor, is supplied through a push-pull amplifier 10 driven by a sawtooth generator and preamplifier 28. The current in winding 12 and parallel convergence circuit 32 flows through an S-correction capacitor 18 and current sensing resistor 20 to ground. A resistor 22 provides feedback to the sawtooth generator, while a resistor 26 is connected to the preamplifier 28 in order to stabilize the current in winding 12. A further resistor 40 is connected in series with convergence circuit 32, and develops a voltage through transformer 42 which is equal in magnitude and opposite in polarity to the voltage produced by the convergence current in resistor 20. Thus the feedback signal through resistor 26 represents only the current in winding 12, which can therefore be regulated independently of the convergence current. In another embodiment, Fig. 3 (not shown), the voltage across resistor 40 is amplified by a transistor to produce a feedback voltage cancelling that produced by the convergence current flowing in resistor 20.
