Title: Improvements in or relating to coin freed vending machines
IPC: G07F11/16
Filed: 1938-10-10
Abstract: 519,951. Coin-freed vending machines BRECKNELL, MUNRO & ROGERS (1928), Ltd., and DOLMAN, H. J. Oct. 10, 1938, No. 29243 [Class 27] In coin-freed vending machines in which the articles are delivered one by one from the bottom of a pile by mechanism which requires re-winding from time to time, a part of the delivery mechanism is located above and clear of the top of the pile and follows the latter downwards as it diminishes through successive deliveries, thus necessitating re-raising of this member with consequential re - winding of the actuating mechanism before the pile of articles can be replenished. Fig. 2 shows a weight 3 mounted over the top of the pile and connected to both h ends of a chain passing round a lower sprocket 26. Thus the tendency of the weight is to rotate the sprocket 26 in a counter - clockwise direction. The sprocket shaft is geared to the shaft 38 so that one complete rotation of the sprocket shaft causes one quarter revolution of the shaft 38 thus causing one of the four arms 31 on a notched wheel to move under the pile and deliver the lowest package. A coin,falling down the shoot 4 tilts the lever 39 to release the lever 46 from the projection 42, but momentarily holds it by the upper projection 43 until the coin rolls off and the lever 39 is restored by the spring 45. The lever 46 is then free to be rotated through one revolution by its geared connection with the shaft 38, thus allowing the sprocket 26 to rotate and effect deivery of an article. In a modification, the member which is located over the pile is an additional weight connected to the main weight through a lost-motion device.

S., 49, Twyford Street, Islington, London, and BROMFIELD, H., 3, Sandgate Avenue, Tilehurst, near Reading. Oct. 17, 1934, No. 29704. [Class 132 (ii)] [See also Group XVIII] Game apparatus in which vertical pins 11 have in front of them a surface 22 with its rear edge above the bottom of the pins, a ring 25 being projected as by hand along the surface so as to fall over one of the pins is characterized in that the pins are carried on one or more members (band 2) which may be moved to bring the pins from a vertical playing position to an inoperative position or vice versa. The ring 25 is projected up a glass surface 22 and through a slot 24, the box 1 being covered by a glass sheet 20. The endless band 2 carries three sets of pins 11, 12 and 13 differently spaced and is mounted on drums 3, 4 of which drum 3 is rigid with a knob 8 outside the casing and a ratchet 9 coacting with a pawl 10 so that the band may be moved forward only, to change the set of pins in use. Such forward movement also carries any rings 25 on the pins 11 or band 2 forward so that they drop into a trough 28. The two sets of pins not in playing position are hidden by the front of the casing and by a flap 26 hinged at 27. The trough 28 is biassed clockwise against a stop to the position of Fig. 1 and is rigid with a rim 28<1>, Fig. 3, having a slot 31. A handle. outside the casing is rigid with a disc 29 having a coin pocket 32. If a coin is dropped down the slot 33 in casing 1, it rests in both pocket 32 and slot 31 so that when the handle rotates disc 29 counterclockwise, the coin carries trough 28 with it ; the rings drop into a shoot 34 and the coin into a lower receptacle. Locking means are provided for holding the band 2 in each of its three playing positions. The band 2 may be of balata ; the pins 11 of metal, wood, synthetic resin or casein product ; and the rings 25 of an aluminium alloy. The pins may be of various colours and heights. In a modification, not shown, the band carrying the pins in the above construction, is replaced by a number of parallel members. Each member is built up of two triangular end pieces connected by three plates carrying the pins. The members are rotatable by sprocket and chain gearing which is connected to the shaft of a forward drum ; from the latter a calico band passes beneath the members to a rear drum, so that as the members are rotated by a handle on the forward drum to change the pins, the band delivers the playing rings to a trough. This construction also is controlled by coin-freed mechanism. Specification 421,751 is referred to.

Title: Improvements in or relating to aircraft
Inventor: DAVIDSON IVOR MACAULAY
IPC: B64C9/38
Filed: 1958-09-18
Abstract: 866,608. Controlling aircraft. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Sept. 9, 1959 [Sept. 18, 1958], No. 29911/58. Class 4. An aircraft comprises a pair of wings having lift control means for varying the lift produced by the wings extending along the trailing edge of each wing, and a control for varying the setting of the lift control means, the wings being cambered with the maximum camber substantially at the mid-chord point of the wings and the neutral point of the aircraft being to the rear of the mid-chord point. The wing 2 has a chord line 41, along which is positioned the mid-chord point O of the chord C and the neutral point N of the aircraft, and a camber line 42 so arranged that the point of -maximum camber coincides with the mid-chord point 0 with the point N always aft of point 0, preferably at 55%C. The aircraft centre of gravity is approximately positional at point O, and though they may be vertically displaced, G will never be aft of N. The camber line 42 may be a circular arc or a parabolic arc. The trailing edge of the wing carries a flap 5 associated with jet propulsion nozzles in the manner disclosed in Specification 787,012 and 823,591, the flaps being controlled for simultaneous movement in the same or opposite directions by mechanism as disclosed in Specification 790,193 and 823,591 in order to deflect the jets. Consequently the lift on the wings, which are set at zero incidence in flight, is composed of a component LF resulting from the jet flap effect and a component LC resulting from wing camber, both components acting at the mid-chord point O. The invention may be applied to a cambered wing 50, Fig. 8, with conventional trailing edge flaps 51 in place of the jet flap arrangement of Fig. 6, though such wing should preferably be provided with nozzles for blowing air out or sucking air in over the upper surface of the flaps for bounding layer control in known manner. An arrangement is described, Fig. 7 (not shown), for a retractable or extension flaps and apparatus such as disclosed in Specification 823,591 is described for actuating the elevators for control during supersonic flight. Specifications 758,269 and 829,753 also are referred to.

Abstract: 1508085 Liquid level detector HECTRONIC AG 20 July 1976 [21 July 1975] 30073/76 Heading G1A A liquid level detector comprises a hollow body 10 of translucent or transparent material having a widened upper part 11 joined to a closed and narrow part 12 by a shoulder 13, a light source 16 arranged in the body so that light passes out through the walls of the narrow part 12 and, in the absence of liquid outside the detector, through the shoulder 13 to reach detector 19. In the presence of liquid, light is refracted away as shown by the dotted lines and does not reach the detector. The path from shoulder 13 to the detector is constructed so that light from directions other than those from the source does not reach the detector. As shown, light from the source 16 is collimated by a lens at the end thereof and strikes conical mirror face 26a. After passing through wall 12c and shoulder 13, the light is directed to the detector by reflecting surface 11b. Opaque block 118 both supports the source and prevents light therefrom reaching the detector directly. The detector may be movable along the axis of widened part 11 to adjust the detector for maximum sensitivity. In alternative embodiments different elements, comprising internal reflecting surfaces and opaque sections to reduce the angles of acceptance may be used between shoulder 13 and detector 19 to reduce the response to scattered or extraneous light. In another embodiment, the source is located at the closed end 12b of the narrow part 12 and the walls 12c of part 12 are inwardly convex to direct the light out of the tube. The detector is annular in this embodiment and preceded by an annular tapering passage between opaque elements replacing elements 111 and 118.
Patent GB-300894-A (GB)
Abstract: 300,894. Clavel, R. Nov. 19, 1927, [Convention date]. Inkless printing; resist printing.-Silk fabrics are loaded by applying in paste form to one or both sides thereof, or in parts to form patterns, a metallic compound such as stannic chloride thickened with gum arabic, dextrin, starch, degradation products of starch, sugar, &c. The silk is then treated with baths containing further loading agents and substances such as alkali phosphates for conversion of the metallic compounds into insoluble substances. Acids or salts having an acid reaction and protective colloids such as size, albumen, &c. may be added to the paste or be applied to the fabric before the treatment with the paste. The paste may also contain sodium silicate. The salts required for the precipitation of the insoluble substances may be. applied by overprinting with a second paste. Variegated colour effects are produced by dyeing the treated fabric with mordant dyes, the dyes being absorbed by the treated parts, the other parts being dyed with other dyes. The treated parts of the fabric exhibit crape effects. When one side only of the fabric is to be loaded, the other side is reserved with a thickener to prevent the penetration of the loading paste through the fabric.

Abstract: 1293099 Controlling I.C. engines FIAT SpA 28 June 1971 [6 July 1970] 30202/71 Heading F1B Hand throttle for an I.C. engine comprises a bracket 3, 4, 5 to the upper limb of which is secured a short smooth-bore socket 10. A tubular member 12 is rotatably received in the socket and is retained by a circlip 14. The upper end of the member 12 has a shoulder 13 and is knurled externally. The member 12 is threaded internally and receives a second externallythreaded tubular member 18, having a plain extension 20 with a flat on it, which passes through a D-shaped hole in an intermediate limb 22 of the bracket. A series of triangular section annular grooves 26 are formed inside the member 18, which can be moved parallel to its axis, relative to the bracket, by rotation of the member 12. A third tubular body 28 extends through and projects beyond each end of the member 18. At the upper end of the body 28 is a button 45, which when depressed withdraws a spring-loaded stop pin 53 from the grooves 26, so that the body 28 may be moved axially relative to the member 18. Connected to the lower end of the body 28 is a cable 34 which runs in a sheath 36 attached to the limb 5 of the bracket, the other end of the cable being connected to a fuel supply control lever. The idling speed of the engine is set by moving the body 28 to its lowest position relative to the member 18, so that the stop pin engages a wide groove 27, and then rotating the member 12 to achieve the required speed. Thereafter discrete increases in engine speed can be obtained by depressing the button 45 and lifting the body 28, which is retained in the raised position by allowing the stop-pin to engage in one of the grooves 26.

Title: Improvements in or relating to travelling wave tubes and the manufacture thereof
IPC: H01J25/38
Filed: 1954-10-20
Abstract: 763,545. Travelling-wave tubes. WESTERN ELECTRIC CO., Inc. Oct. 20, 1954 [Oct. 21, 1953; Oct. 21, 1953], No. 30211/54. Class 39(1). In a travelling-wave tube comprising an electron gun assembly 10 and a collector assembly 11 connected by an elongated glass envelope 12 enclosing a helix 14 supported by three rods 15 preferably of ceramic material, increase in the temperature of the helix, due to excess radio frequency power which the helix is unable to transmit with consequent decrease in power output and efficiency, is reduced by collapsing a portion 18 of the envelope 12 into intimate contact with the rods 15 over a significant portion of their periphery. The length of the portion 18 is preferably about one third the length of the helix 14, and the envelope is collapsed from the shape shown in Fig. 2 to the shape shown in Fig. 3 in which the envelope is in contact with the rods 15 over a third or more of the periphery of each rod. The collapsing operation is carried out using the circuit arrangement shown in Fig. 6. An aligning tube 24 at one end of the helix 14 is connected by a lead 31 to a terminal pin 17, and a support ring 28 at the other end of the helix is connected through a fuse wire 30 to the collecting cylinder 27 to establish through the helix a direct current path which is completed by a lead 32, switch 33 and battery 39. The envelope is exhausted by a vacuum pump 36 connected by rubber tubing 37 to the collector cylinder 27, and current is passed through the helix sufficient to soften the glass envelope but not to such an extent that collapse occurs. A heat reflecting cylinder 40 is placed around the envelope to provide the additional heat necessary to allow atmospheric pressure to collapse the envelope. The cylinder 40 may cover the whole length of the envelope to be collapsed, or may be moved along the envelope, and is provided with a thermocouple 42, preferably in contact with the envelope 12, and a meter 43 to enable the collapse to be stopped before the envelope comes into contact with the helix. Either before or after the collapsing operation, the cylinder 40 is removed and the helix outgassed by passing a current through the direct current path. When evacuation has been completed, the fuse wire 30 is burnt out by application of a short high current, and the collector cylinder 27 is then sealed off. Specifications 726,823 and 734,771 are referred to.
