Abstract: 1,064,908. Housings for electrical equipment. STANDARD TELEPHONES & CABLES Ltd. Nov. 10, 1965, No. 47658/65. Heading H1R. [Also in Division H2] A housing for an apparatus assembly has a mounting plate 2 connected to a base-plate 1 by a series of plugs 4 and sockets 3 (Fig. 1, not shown). The housing has a cover 6 firmly held against the mounting plate by a U-shaped handle 7 pivoted in brackets 8 on the base-plate. This handle 7 may be moved either in the direction " B " such that extensions 18 engage the underside of the mounting plate 2 and detach this and the cover from the base-plate or, alternatively, in the direction " A " where only the cover 6 is released. In a modification (Figs. 3 and 4, not shown), a block (16) is attached by a bracket (11) to the mounting plate, the block projecting through an aperture in the cover, the bracket being attached to the cover by screws (15). When the cover has been removed, the handle may be returned to a position on the block (16) where it is gripped by the block, thus ensuring firm contact between the mounting plate 2 and the base 1. Extra gripping means may be provided by a spring clip arrangement (20, 17).

The delayswitch, however, produces a signal corresponding to logical one in the absence of a natural heart beat and as such, the pulses produced by the combination of the oscillator-divider are gated to the electrode 11. The delay switch comprises a full-wave rectifier including diodes (44, 46), Fig. 2 (not shown), so that the switch responds to both positive and negative natural heart beat signals, a parallel combination of a timing capacitor (50) and a timing resistor (54) determining the said pre-determined period, an inverter (66), and a transistor (60) which is non-conducting in the absence of a natural heart beat signal, but which starts conducting almost instantly following the occurrence of a natural heart beat for the said pre-determined period, which may be 0.3 secs. The quartz crystal oscillator 18 comprising a digital clock circuit, and the frequency divider 20 use integrated circuit chips. An electrode 12 at ground or reference potential, is either placed in contact with the heart or is subcutaneously connected to any other part of the body.

Reduction in contrast of the picture produced on the screen 2 (Figs. 1 and 2) of a television receiver and caused by the reflection of ambient light at such screen is minimized by means of a removable translucent cover-plate 6 which is also partially light-absorbent so that ambient light which traverses plate 6 twice (i.e. before and after reflection) is attenuated to a greater extent than light originating at the screen 2. Plate 6 is preferably made of plastic in which a glass section may be embedded and the area not coincident with screen 2 may be made opaque. Additionally, plate 6 may be formed with an aperture coincident with screen 2 in which may be positioned either selected ones of a plurality of translucent/absorbent sections of different characteristics (some of which may be colour selective) or a selectable number of similar sections. The area of plate 6 coincident with screen 2 may be formed as a magnifying lens 13 (Fig. 2) or as a stepped Fresnel lens as shown in Fig. 3. The plate 6 which is provided with an aperture 9 giving access to the receiver controls 4 fits over a projected edge 5 at the front of the receiver and is retained by means of lugs 7 and co-operating recesses 8. When not employed for the prevention of contrast reduction plate 6 may be utilized as a base support for the receiver when the latter is operated on an uneven surface.

Abstract: 1,062,069. Rolling. MORRIS MOTORS Ltd. Nov. 17, 1965 [Dec. 1, 1964], No. 48682/64. Heading B3M. A machine for rolling splines, screw threads or worms in a metal article comprises a pair of heads (3), (4) carrying rolls (5), and slidable on slideways (2), and hydro-mechanical means for moving the heads so that the rolls engage the workpiece simultaneously. The axes of the rolls (5) lie on the same horizontal plane as the axis of the workpiece, and the latter is carried in a fixture (6), comprising a centre (7), and a live centre (8), carried in a sliding tailstock (9). The centre may be replaced by V-plates, or a combination of V-plates and centres may be used. The drive for the rolls is provided by an electric motor which drives a belt and adjustable pulley arrangement connected to a main drive box (10), the output shaft (11) of the box drives shafts (18), (19) through gears (13), (15), and each of these shafts is connected to the arbor (24) of a roll (5) by a worm and wheel (20), (21), a shaft (22), and helical gearing (23). Shaft (18) is journalled in a floating housing (25), Fig. 6 (not shown), and can be axially adjusted to by a micrometer (26). Sliding heads (3), (4) are actuated simultaneously to move the rolls relative to the work by levers (36), which are connected to recirculating ball type lead screws (35), Fig. 1 (not shown). The latter are moved axially by nuts rotated by shafts (32), (33), fixed on to a worm-wheel (30), rotated by a worm (29), driven by an hydraulic motor (28). The limits of travel of the heads are controlled by adjustable stops (41), (42). Backlash in the gearing is eliminated during feed movement of heads (3), (4), by a self-adjusting brake (43), Fig. 5 (not shown), fitted on to each roll arbor (24). Each brake comprises a drum (44) keyed to the arbor, and a friction member (45) riveted to a shoe (46) pivoted at (47). Each of the brakes is applied during movement of the head towards the work, by a spring- loaded button (48). However, when the head is retracted, a rod (49), Fig. 2 (not shown), abuts the stop (42) and displaces rods (50) (51), so that a plunger (52) disengages the brake.

A combined amplifier and mixer or separator comprises a field effect transistor 12 (Fig. 2) having a low voltage rating and high gainbandwidth product having its source-drain path in series with the emitter collector path of a bipolar transistor 20 having a high voltage rating and dissipation whereby transistor 20 provides across its load a voltage swing larger than the rating of the F.E.T. The circuit shown is used for the video stage of a television receiver, the sound carrier being selected by a timed circuit 45, 46 and the video signal being passed by way of series and shunt peaking chokes 23, 25 to the C.R. tube 41. In Fig. 3 the circuit is used to amplify the R-Y, B-Y and G-Y and Y signals in a colour television receiver and to mix the colour signals with the Y signal. The Y signal is applied at 51 to a preamplifier FET 50 having a negative feedback gain control 53 and a brightness control 57 which varies the voltage on a second gate, the control voltage being obtained from a horizontal scanning pulse H. The output is derived via a peaking and matching circuit 60- 64 via a delay line 52 and matching circuit 70, 73 and is applied to the gates of F.E.T.'s 75, 76 and 77. The R-Y and B-Y signals are supplied to F.E.T.'s 95 and 99 connected in parallel with 75 and 77 to effect mixing. The R-G signal is derived from the outputs of 95 and 99 and applied to an F.E.T. 106 in parallel with 76 to effect mixing, feedback through resistor 102 effecting correction of the signal. The outputs from the parallel pairs of F.E.T.'s are fed to three bipolar transistors 90-100 to form series circuits basically of the Fig. 2 type. The R, Y and G signals are fed to the CR tube via peaking circuits such as 91, 92, diode 132 serving to protect the gating circuit. It is suggested that the mixing with the luminescence signal could alternatively be effected at the CR tube control electrode.
