Title: Improvements in latches for doors
IPC: E05B65/22
Filed: 1923-05-15
Abstract: 215,579. Sleigh, H. L., Cheston, A. S., and Edmonds, E. C. May 15, 1923. Latches, sliding. - In a latch fastening for motor vehicle &c. doors of the type in which an extension of the handle engages the latch or part carried thereby so that the latch can be withdrawn by turning the handle, the latter being retained in its normal position when the door is slammed by a spring-controlled slide, the slide is housed in a recess in the latch and is provided with an opening through which the handle passes. The spring-shot latch bolt 1 is formed with a channel 6 terminating in a slot 7 and formed with ledges 8 on which a slotted member 9 is adapted to slide, the end of the slide 9 extending into the slot 7 being formed with a projecting lug 10 which projects through a slot 11 in the latch casing 2. A coil spring 12 mounted in the slot in the slide between the lug 13 and a stop 14 on the casing 2 tends to urge the slide outwards. The extension 16 on the handle 15 passes through the slots in the casing, slide and latch bolt, its hooked end being engaged with a bridge-piece 4 secured to the casing 2. The latch bolt 1 is withdrawn against its spring 5, on turning the handle 15, by the slide 9 engaging the inner end of the slot 7. When the bolt 1 is withdrawn on the door being slammed, however, as shown in Fig. 5, the handle 15 is held in its normal position by the slide 9, the lug 10 being held by the spring 12 closely against the edge of the extension 16 of the handle.

Title: Improvements in or relating to servomechanism
Inventor: LAMBERT DONALD RUDOLF
IPC: G05G17/00
Filed: 1955-05-04
Abstract: 786,791. Linkwork. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. April 6, 1956 [May 4, 1955], No. 12946/55. Class 80(3). In a mechanical servomechanism, particularly for record controlled statistical machines, the movement of a slidable bar 13 actuating a switch or other mechanism is determined by a small stationary electromagnet 8 controlling a bar 2 pivoted on a driving member 1 which is reciprocated, by means not shown, in the direction of-the arrows. The bar 2 is held by a spring 4 against a pin 18 and has a notch engaging the overturned end of the pivoted armature 6 of the electromagnet 8. In the position shown, the member 1 engages a spring 5 to hold the armature 6 closed. If the electromagnet is energized during movement of the member 1 to the left the armature remains closed and its upper end causes the moving bar 2 to be rocked to a position wherein its nose 17 engages and shifts the bar 13, which may be returned by a spring or other means. If, however, the electromagnet is de-energized during movement of the member 1, the bar 2 reciprocates idly, opening and closing the armature 6 without affecting the bar 13. A switch 12 in the electromagnet circuit may be controlled manually, mechanically or electrically. The member 1 may carry a plurality of bars 2 each controlled by a respective electromagnet 8 to operate a respective bar 13.

Title: Guidance system
Inventor: BURTON JOHN ROBERT
IPC: F41G7/26
Filed: 1961-04-11
Abstract: 930,961. Automatic steering control. Mc- DONNELL AIRCRAFT CORPORATION. April 11, 1961, No. 12981/61. Class 38 (4). [Also in Groups XXI and XL (c)] In a system for guiding a missile, detectors spaced round the missile respond to a beam of energy defining a path for the missile and control appropriate thrust producing means spaced round the missile so as to correct deviations of the missile from the beam by transverse movements without turning. In Fig. 2 a rocket missile launching tube 54 is aimed at a target with the aid of a sighting device 56. After firing, the missile is above a trough-shaped beam of infra-red light 40 emanating from a projector 39. A number of photo-cells 19, Fig. 1, are mounted on fins 14 which move outwards after launching, and when the missile descends into the light beam due to gravity, one of the cells responds to the light and detonates a propellant charge 18 in a recess located at a corresponding position round the circumference of the missile. The jet side-thrust thus produced together with similar thrusts produced by other photo-cell/charge combinations as the missile rolls, maintain the missile within the trough during its short flight. Charges 18 are located approximately at the centre of gravity of the missile to avoid turning effects. Mounting of the photo-cells directly on the missile without fins is referred to. In a modification each charge is replaced by a longitudinal row of charges, and pairs of charges in each row, equally spaced from the centre of gravity of the missile are available for detonation so that a flight of longer duration may be controlled. In another modification the charges are replaced by motor-operated control surfaces. Maintaining the missile within a beam of annular cross-section or maintaining it in the radiation instead of outside are referred to. Use of a radio beam is also referred to.

Abstract: 888,685. Dynamo-electric machines. SELECTRA Ltd., and KREBS, E. W. April 24, 1958, No. 13090/58. Class 35. In an induction motor with axial air-gap, the radial slot-windings are connected at alternate ends to form a wave-shaped winding. As shown in Fig. 1, the stator of a 12-pole, singlephase, shaded pole motor has a preformed wave-shaped winding 15 lying in open slots 12, and a short-circuited shading conductor 18 lying in semi-closed slots 17 parallel to the adjacent main winding slot. The core 10 is made of spirally-wound strip. The shading conductor, which is formed by threading through the slots 17 serves to secure the main winding in position. A squirrel-cage or wound rotor may be used. A capacitor motor is described in which the main and auxiliary windings are disposed in alternate deep and shallow semiclosed slots. Fig. 5 shows a change-pole winding 25 arranged in sixteen slots, and composed of two wave-shaped windings 26, 27 which may be energized similarly or oppositely to produce 8-pole or 16-pole operation. In polyphase machines, the phase windings may occupy different axial positions.

Abstract: 700,932. Open fireplaces. TUOHY, P. J. June 5, 1951, No. 13363/51. Class 126. In a boiler and boiler flue construction for use with open fireplaces the back and sides of the flue, the boiler supports and the skirting base are cast in metal as an integral unit, the flue back itself being shaped similarly to the bottom, rear and adjacent portion of the top of a semi-elliptically shaped boiler, constituting therewith a curved flue hugging the boiler for the major surface portion thereof. As shown the flue back 4, sides 4a, and skirting base 4b are cast integrally, the sides being rebated at 2a in order to support a boiler 1. A curved plate 5 extending between the sides continues the curved flue 2 around the top portion of the boiler leaving a throat 5b connecting the flue 2 with the main flue 6. The front of the integral unit is closed by cover plates 12, 19, the former being provided with an opening 11 which is normally closed by a door 15. The combustion gases from the fireplace are caused to flow through the boiler via ducts 3 as well as round the boiler through the flue 2. Flow of combustion gases up the flue 6 to the chimney is controlled by a sliding plate damper 16. The back 4 and sides 4a of the flue 2, below about the position where the plate 5 is fitted to the back 4 are preferably cast in a heavier gauge metal than the rest of the unit.
