Abstract: 1,090,929. Endless tape cassettes. COUSINO ELECTRONICS CORPORATION. Oct. 15, 1965 [Dec. 18, 1964], No. 43830/65. Heading G5R. A cassette in which a disc 38 supports the majority of a magnetic sound tape in a coil in the manner of Specification 793,521 has the following detail improvements:- (a) The tape portion 55 is arranged for feeding and playing in a plane parallel to the disc 38, saving cassette height by entrainment of the tape over guides 32, 33, Fig. 3. (b) Guides 27, 28 transfer the return tape portion 56, Fig. 3, to a position 57, advanced relative to the tape feed-out point 53, encouraging a gap 58 in the tape coil, which eases feed-out at 53. (c) When not in a playing machine, tape 57, Fig. 5 is nipped between the disc 38 and ribs 69 on the cassette lid while the disc is held against rotation by teeth 48, 49 on the disc 38 and on a member 34 raised by a spring 41. A member 70, Fig. 7, on the playing machine, depresses the member 34 when the cassette is loaded to release the tape. The cassette is loaded into a slot 76, Fig. 7, and latched by means 79, 80 and a blade-spring 92. It is tilted as shown to clear the means 79, 80 to remove it. The pinch roller 18 may be engaged by hand or automatically by solenoid. The head (Figs. 12-14, not shown) may be slidable to play any of four alternative tracks.

Abstract: 1,064,677. Pivots. HOOVER Ltd. Dec. 10, 1963 [Nov. 21, 1962], No. 44102/62. Heading E2F. A foot assembly for a fan heater comprises at least one support member, a T-shaped foot 19 mounted for movement in a generally linear direction relative to the support member between a retracted and an extended position, and means to permit relative pivotal movement of the support member and the foot in the extended position. The support member is a channel section frame 10 attached to the heater and having a vertical slot 15. A rivet 16 extending through the slot clamps the head 18 of the foot 19 to one side of the frame web 11 and clamps a friction disc (50) Fig. 3 (not shown) via a dished spring washer (51) to the other side. Between the head 18 and the friction disc (50) is a slide plate 30 and a spider like spring (32) Fig. 2 (not shown) having spring arms (33- 36) which have protuberances (42) running in vertical grooves (40) either side of the slot 15. Adjacent the end of the slot 15 and in line with each groove (40) is a circular hole (44) in the web 11 into which the lower pair of protuberances (42) can ride when the foot is extended, (full lines Fig. 1). The foot 19 can pivot with frictional resistance relative to the frame 10 and the foot head 18 has limiting stops 60, 61 engaging a sprag 62 of the slide spring (32) and extending through a hole (63) in the slide plate 30. In another embodiment Fig. 6 (not shown), the foot 19 pivots frictionally about a plate (70) having slots (80, 81) through which extend screws (82, 86, 87) so that it can move linearly of the support member. The plate (70) is latched in the position shown by a spring lever (90) engaging a slot in a flange of the plate. A protuberance (95) on the foot engages a pivotal limiting stop (96).

Abstract: 1523123 Analogue to digital converter TELECOMMUNICATIONS RADIOELECTRIQUES ET TELEPHONIQUES 27 Oct 1975 44113/75 Heading H3H In a cascaded a-to-d converter, for producing a Gray code, at least the first stage comprises a comparison unit K 1  having two comparators using references respectively above and below the average input value, and a transfer unit U 1  having a piece-wire straight line characteristic with discontinuities substantially at the reference values. For an input V 2  (Fig. 8) an output 24 passes to the next stage from the transfer unit while the comparator outputs, inverted, are passed to a word comparator 70 where words are compared as in Fig. 7. For word equality e9 = 1 and sign digit C forms output on d 1 , for b 1  a 2  b 3  a 4  greater, M = 1 and these form outputs on d 2 -d 5  and d, and vice versa when M = 0. The transfer characteristic slopes may have a companding effect and the digital output may be clocked (Fig. 14, not shown). The converter is said to be sensitive to small fluctuations around its zero point with amplifier drift, only affecting higher significance outputs.

Abstract: 1,013,286. Pressure responsive switches. GENERAL METALS CORPORATION. Nov. 22, 1962 [Dec. 12, 1961], No.44250/62. Heading H2B. A microswitch 52 is operated by an actuator pad 48 attached to the wall 34 of a doublewalled, hollow metallic diaphragm unit 32 disposed within a cavity defined by the wall of the base 14 of the switch housing and a rigid dome-shaped cap 18 secured thereto so as to limit expansion of the diaphragm in response to a pressure rise from inlet 42. The switch 62 is carried by a leaf spring 64 which is secured to the base 14 together with a bracket 76 by a screw 74. The leaf spring 64, which is flexible to permit pivotal movement of the microswitch and the bracket 76, are biased apart by a spring 82, which may be adjusted by means of a screw 84 reached through a cap 88 in the housing to vary the pressure setting of the switch. The diaphragm unit 32 may be in two parts welded, brazed, soldered &c. together and may be made of stainless steel and/or beryllium copper. 1,013,293. Automatic circuit breakers. ROWAN CONTROLLER CO. Dec. 15, 1961 [Jan. 5, 1961], No.45050/61. Heading H2B. In a circuit breaker the main contacts 42, 43 of which are closed or opened on depression of a spring-biased push-button 19, and in which latch means hold the button in a depressed condition while contacts 42, 43 are held closed by a further latch which is sensitive to current conditions, auxiliary contacts 73, 74 are arranged in an indicator circuit to be held either open or closed whilst the button is depressed. The indicator is a bulb 75 mounted in the outer end of the push-button 19 and provided with a translucent cover 87. A projection 70 on the button bears against a leaf spring 71 to operate the auxiliary contacts 73, 74. The movable contact 43 is carried by a spring urged contact plate 32 pivotally mounted on a further plate 27, which latter has a finger part 68 engageable with an inclined shoulder 65 of the push button to latch it in a depressed condition. The current sensitive latch is provided by a generally J-shaped bimetallic element 36, riveted to contact plate 32 and having a free end 38 engageable behind a latch surface 57 of the plate 27 when the push-button is depressed. Unlatching occurs on the passage of an overload current through the element 36 or, alternatively, on a second depression of the push-button whereby an inclined cam surface 62 thereon forces the element 36 out of engagement with the surface 57, whereupon a spring 48 urges the contact plate 32 clockwise as shown, to open main contacts 42, 43, and the finger part 68 of plate 27 disengages from its latching shoulder 65 to release the pushbutton and allow auxiliary contacts 73, 74 to open.
