Abstract: 957,225. Road traffic signals on vehicles. FORD MOTOR CO. Ltd. Nov. 7, 1962 [Dec. 8, 1961], No. 44102/61. Heading G4Q. The rotor 6 of a self-cancelling indicator switch carrying spring pressed contacts 15 is returned to its "off" position after completion of a turn by the engagement of a cam 1a or 1b on the steering column with the outer end of a spring- centred striker 9 pivoted on switch case 10, such engagement in turn causing striker 9 to engage one of the yieldable striker pins 7 on rotor 6. The pins 7 are urged towards each other and against rotor abutments 10 by a strong spring 8 so that the pins are held substantially rigid with the rotor 6, it being possible to override the cancelling action by holding or moving switch lever 11 in or to the "on" position when the appropriate pin 7 will yield. Rotor 6 is positively held in its "on" and "off" position by a spring pressed ball 13.

Title: Electro-optical transistor chopper
IPC: H03K19/14
Filed: 1964-11-03
Abstract: <PICT:1065450/C4-C5/1> An electro-optical transistor chopper (see Division G1) comprises a light-emitting semi-conductor diode optically coupled to a transistor or transistors.  The diode comprises a hemispherical region of N-type conductivity 92 and a P-type region 94.  When forward biased, the rectifying junction 96 between the regions emits light which passes through the antireflection coating 108 and is reflected by the gold mirror 104 on to a transistor having two emitters 84, 86 diffused into a base region 82 which is itself diffused into a collector substrate 80. The transistor and the diode are stuck together by a pliable transparent cement 102.  To avoid absorption of radiation in the hemisphere, it is composed of material having a larger band gap than the material in which the junction 96 is located.  Ga As0. 6 is preferred for the region in which the junction is located and Ga Asx P1-x, where x \s5 0.5 for the hemisphere. Indium-gallium arsenide may be used.  Either the junction is diffused into the hemisphere which is subsequently etched to produce the region 94, or the region 94 is produced epitaxially. The transistor is composed of germanium or silicon.  In modifications the double emitter transistor is replaced by two transistors connected in parallel, Fig. 14 (not shown), or with commonly connected collectors and bases, Fig. 9 (not shown).  In these embodiments the transistors are formed on a glass substrate. In another modification, Fig. 10 (not shown), the N-type region of the light-emitting diode is of planar form.

The vibration may be provided by several vibratory drives, or by a single drive 7 located either adjacent the centre of the cascade, so that the upper and lower halves of the cascade vibrate with different amplitudes, or located at the centre of gravity of the cascade, with adjustable masses fixed to either half of the cascade to provide the required respective magnitudes of vibration. The base 9 of each annular surface may be doublewalled, and heated by steam, fed individually to each surface through a control valve, or cooling gas may be fed to nozzles in the base of each surface to agitate the material. Alternatively the material may be agitated by rotary vanes, or by providing gravity shoots on each, or between adjacent, annular surfaces. When used for vacuum drying, e.g. plastics, a pump 5 is used to generate the required vacuum.

Title: Device for dispensing and applying a pressure sensitive, heat sensitive or pressure heat sensitive tape
IPC: B65C11/00
Filed: 1966-10-11
Abstract: 1,118,370. Applying adhesive labels cut from strips; securing articles to cards. TAPELER CORP. 11 Oct., 1966 [22 Oct., 1965; 25 April, 1966], No. 45494/66. Headings B8C and B8F. A feed member 29 of square cross-section, Fig. 2, in a device for applying lengths of pressure- or heat-sensitive tape, has at each of its four corners, an axial cutting edge which co-operates with an anvil 38 to sever a length of tape from a reel 11, the tape being retained on the feed member by prongs 39. Shafts 25 and 26, which support the anvil 38 and feed member 29 respectively, are carried at each end in frames 24 affixed to the casing of the device by springs 28. A pawl 32, pivoted on members 20 at the bottom of an actuating stem 16, engages with one from a set of four pins 30, which extend through the end of the feed member. When an operator depresses the actuating stem, the pawl turns the feed member through 90 degrees anticlockwise, whilst the anvil acts with the cutting edge between faces 29A, 29B of the member, thus to sever the tape held on face 29B which turns parallel to a surface (36), Fig. 4 (not shown), the adhesive side of the tape being disposed downwards. During the depression of the stem 16, the members 20 engage with the frames 24 and force them downwards until the face 29B is pressed against the surface (36), the prongs on the face being pushed into a recess 26A in shaft 26. In a second embodiment, Figs. 10-12 (not shown), the frames, carrying the anvil and feed member, are supported by the inturned shoulders of a pair of hangers (40). When the actuation stem is depressed, side members (120) at the stem base wedge the hangers apart and push the frame downwards. The anvil (138), Figs. 6, 7 (not shown), has grooves to facilitate only partial severance of the tape, complete severance occurring by rupture after the tape is applied to the surface (36). A rubber strap (47) around part of the reel periphery imparts resistance to rotation and a roller guides the tape to the feed member. For heat-sensitive tapes a heater (48) is located in the shaft of the feed member. In a third embodiment for use with weak tapes, an arm 51, Fig. 13, pivoted at 52 and carrying a roller 53 is upwardly biased against a stop 57 by an adjustable spring 55. The sudden pull, caused by the turning of the feed member 229, is cushioned by the roller 53 yielding towards a lower stop 58. Reel 211 is biased by a coil spring (64), Fig. 17 (not shown), and a roller 245 is equipped with a one-way clutch. If a normal strength tape is used the roller 53 is by-passed. The feed member may have transverse channels (67), Fig. 19 (not shown), for mounting an article, e.g. a pencil on a surface, such as a card, and the channels may each have an insert of foam rubber (68).
