Title: Improvements in and relating to change-speed gearboxes
IPC: F16H63/18
Filed: 1947-05-29
Abstract: 638,301. Controlling change-speed gearing. MAGIS, A. A. G. May 29, 1947, No. 14278. Convention ' date, April, 8, 1943. [Class 80 (ii)] In change-speed gearing having constant-mesh gear pairs brought selectively into action by dog clutches all situated on one gearing shaft, the clutches are actuated by sliding normally to the shaft a common operating member having on opposite sides of the shaft duplicate cam plates with cam grooves or slots engaged by diametrically opposed trunnions on each clutch fork. As shown, applied to a motor vehicle, an input pinion 4, Fig. 1, drives through a gear 14 a layshaft 16 carrying gears 15 meshing, directly or through a reversing idler 17, gears 6 connectible to the output shaft 2 by dog clutches 5 slidably splined thereon. Trunnions 11, Fig. 2, on the clutch forks 10 engage cam slots 12, Fig. 3, in the side plates 13 of an operating member connected by arms 18, slidable in the gear casing, to an operating bell-crank lever 20, 19 co-acting with a notched quadrant 25. Stops 27 prevent movement of the forks 10 perpendicular to the shafts. Movement of the lever arm 19 in one direction gives successive gear ratios from reverse to fourth speed or vice versa, with a neutral position between each ratio. As applied to a bicycle bottom bracket gear, pinions 31, Fig. 10, clutchable to the crank shaft 30, mesh pinions 33 rigid with a layshaft driving through further gear pairs 35, 36 a'shaft carrying the chain wheel 38. An operating member 41 controls the clutches 32 as before to give four forward speeds. Gearing according to the invention is also applicable to rolling mill trains or machine tools and, when used for the latter, two gears of the kind having parallel driving and driven shafts may be employed in series to give multiple ratios.

Abstract: 1,159,003. Machine tool details. MULHEAD ENG. CO. Ltd. 29 March, 1967 [31 March, 1966], No. 14318/66. Heading B3B. A transfer machine has a base structure supporting a plurality of separable bed segments 11 which together define a closed circuit for a series of work-carrying platens 13 which occupy the whole circuit, are slidable over the segments 11, and are interconnected for simultaneous indexing with relative play to permit accurate individual location relative to tool heads 12. The bed segments 11 have a channel or groove 22 into which project sets of guide rollers 85, 88 mounted on the underside of the platens. A helically grooved cam 101 mounted in bed segment 11a co-operates with lower depending rollers 86 on the platens to index the entire train thereof to the approximate positions required. Hydraulically-operated plungers 14 project into holes in the platens to locate them accurately and individually in each work station and hydraulicallyoperated clamps 15, 16 act simultaneously and equally on the outer and inner flange portions of the platens to clamp them to the bed segments 11. Compressed air is supplied during indexing to recesses in the slide surface of the bed segments to facilitate sliding of the platens thereover. The platens are interconnected by bolts 73 having spring members 173, 174 under the bolt head and nut to allow for sufficient relative play between the platens. Plates 79, 80 also interconnect the platens and are bolted thereto through clearance holes to allow for this desired degree of play. Plate 79 acts to protect the joints between the platens from swarf. Swarf shoots 19 and a discharge conveyer 20 are provided in the bed. Further tool heads may be mounted around the circuit on suitable pedestals 105. Straight bed sections may be incorporated in the circuit though this necessitates removal of the central guide roller from each platen.

Abstract: 772,531. Ammunition projectile fuzes. BRINRO, Ltd. May 22, 1953 [June 6, 1952; June 12, I952], No. 14523/53. Class 9 (1). [Also in Group XL (b) ] The initiating -apparatus ofa projectile fuze e.g. a proximity fuze comprises a radiation responsive means and an optical system including a mirror rotated to scan an object field and to project successive partial images of the object field on to the radiation responsive means. In the Fig. 3 embodiment a plane mirror 10 inclined to the axis of motion is rotated about that axis and projects on infra-red sensitive photo-cell 3 through lens 12 partial images of an object field which is restricted by an aperture defined by zones R of transparent housing 14 coated with opaque material to the space between two conical surfaces. A wide angle forward facing blind zone is used to prevent premature operation of the projectile fuze, the angle exceeding 180 degrees where delayed action is required. The' mirror is rotated by the spinning of the missile, by motors driving ancillary apparatus or as in Fig. 3 by a winddriven turbine 16 in the nose, the speed being such as to ensure virtually instantaneous scanning of the whole field. The mirror inclination may be adjustable to vary the shape of the blind zone. A system for a proximity fuze to be initiated in response to increases or decreases of radiation of the type caused by a target coming within the object field of the optical system is described in Group XL (b).

Abstract: 728,897. Feed-water &c. heaters; steam generators. ROSSI, G. June 21, 1951 [June 21, 1950], No. 14810/51. Classes 64 (1) and 123 (2). A tubular heat-exchanger (e.g. in a steam boiler) comprises plane walls made up of upright contiguous tubes connected between headers and defining a fluid passage the crosssection of which decreases in the direction of flow of a fluid (the external fluid) flowing over the walls in a direction normal to the tube axes. The change in cross-section of the fluid passage may be gradual as shown for example in Figs. 10 and 11 or it may comprise successive steps as shown for example in Fig. 8 in which the distance between parallel tube walls 12 successively decreases. Fig. 2 shows part of a steam generator in which the passages E, P of decreasing cross-section are formed between walls A of boiler-water tubes and walls D, D<SP>1</SP> made up of return tubes, the combustion gases flowing generally vertically from the combustion chamber B over the top of the headers interconnecting the tubes of one of the walls A and then laterally through the narrowing passages in the direction of arrows K before flowing finally over spaced tube-walls F defining a feed-water heater. In another arrangement, Fig. 4 (not shown), the gases leaving the combustion chamber flow to the narrowing passages through gaps formed in one of the tube walls. The headers may be partitioned so that the internal fluid flows through groups of series-connected tubes. The tubes are attached by welding to the headers which are provided with bushes into which removable plugs are fitted to facilitate cleaning of the tubes, Fig. 15 (not shown).

Title: Improvements relating to cutting by oxy-acetylene and like jet cutting processes
IPC: B23K7/00
Filed: 1922-02-27
Abstract: 202,933. Godfrey, A. Feb. 27, 1922. Perforating or dividing by fusion. - In an oxyacetylene or like jet cutting machine having mechanical means to support and feed the blowpipe, heavy parts such as gas cylinders, gear boxes, and driving- motor are carried by an independent truck or other independent means moving in sufficient conformity with the blow. pipe to avoid excessive lengths of connections between such parts and the blowpipe. Blowpipes 11, 11<a>, suspended at an adjustable height from the work or supported therefrom by adjustable rollers 53 are respectively carried direct from and through a jointed or pivoted and telescopic arm 52 from a slide 8 which may be fed along a slideway 5 itself traversible along a series of connected girders 1 secured to cross-members 3, supported on pillars 4. The slide 8 may also have means to engage a template 55 and screws 54 may fix the jointed arm or be freed so that a member over the blowpipe 11<a> may be pressed against a stationary or revolving template while one of the feeds is engaged or while the work is rotated on a central table. The blowpipe 11 is carried by a sleeve 12 provided with an extension 12a adjustable by a screw 14 in a rotary head 13. The blowpipe 11<a> may be set to cut a bevelled edge. The feeds are described in Specification 202,666 and are derived from a flexible shaft 15 connected to a spindle driven by variable-speed friction gear 67, 68 from a motor 66 or other power. The blowpipes are connected to the gas cylinders 62, 63 by flexible piping 65 through controls 64. The motor, gearing and gas cylinders are mounted on a wheeled truck 60 or other independent carriage which is provided with an operator's platform 60<a>, which may be driven in synchronism with the feed of the slide 5 along the girders 1, by gearing 69, 70, worm gear 71, and friction roller 72 engaging the rail 61, the friction roller being pressed against the rail by an eccentrically mounted roller 73 operated by a hand lever 74. Surplus lengths of flexible pipes are taken up by passing the pipes over a fixed sector on the blowpipe slide and over a fixed and a counterweighted movable roll mounted on the truck. The machine is particularly applicable for cutting out a locomotive side frame without resetting the work, as described in Specification 202,666. Specifications 130,450, 163,432, 163,625, 202,932, and 202,934, are also referred to.

Title: Device for terrain photography by means of scanning systems
IPC: G03B7/22
Filed: 1968-03-28
Abstract: 1,222,231. Aerial photography. NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY, TRADE & COMMERCE FORSVARETS FORSKNINGS INSTITUT. March 28, 1968 [March 29, 1967], No.14875/68. Heading G2A. In an arrangement for photographing the ground from an aircraft, in which the terrain is scanned by a rotating mirror and the elemental strips are projected on to a photographic film, the magnitude of the elemental area ## is automatically changed according to the height h and velocity v of the aircraft. This enables the strips on the ground which are scanned successively to be in abutting relationship, as well as the corresponding strips produced on the film. Fig.2 shows an embodiment in which the terrain is scanned transverse to the line of flight by a rotating roof edge mirror D 1 , so that two scans are carried out in one rotation. The radiation (e.g. infrared) from the ground is reflected from mirror D 1 , through a defocusing system D s , to a detector D, whose output modulates a lamp M. The defocusing system D s  is shown in more detail in Fig.3, and comprises a fixed plano-concave lens L c2 , and a movable planoconvex lens L c1 . The two lenses are cylindrical, and such that they fit together to form a plane sheet. The movement of lens L c1  is controlled by a servomotor, which receives a signal from the velocity and altitude gauges of the aircraft. Thus the elemental scanning area ## is varied in the direction of flight, but not in the direction of scanning. Signals from detector D are received by lamp M, which is modulated thereby, and the modulated light passes through a field lens L and an automatically controlled slit to a roof edge mirror D 2  which rotates synchronously with mirror D 1 . The light is reflected from mirror D 2  through rotating microscope objectives M o  on to a moving film. An alternative method of automatically varying the elemental area ## in the direction of flight is by using a zoom optical system, whose focal length in the direction of flight is controlled automatically by the v/h value. In a third method, Figs.5 and 6, (not shown) the amount of light reaching a photo-electric cell is varied by a diaphragm whose size varies according to the v /h value.
