Title: Improvements in and relating to Propellers or Aircraft.
Inventor: CLEAVER HOWARD CRUNDEN
IPC: B64C11/20
Filed: 1917-09-08
Abstract: 118,683. Cleaver, H. C. Sept. 8, 1917. Screw propellers. - Two-bladed laminµ for assembly as screw propellers are constructed of multiple parts with edge-to-edge diametrical or diagonal glue joints. A large number of modifications are described, of which Figs. 3, 4, 5, 8, 9, 10, 12, 13, and 15 show examples, the principle being that when the laminµ are not sufficiently wide to give the requisite strength at the hub, the additional pieces D, D<1> are fitted, as shown in Figs. 9, 12, 13, and 15. These laminµ are assembled fanwise as shown in Fig. 2, which also shows the hub-pieces D, D<1>. In constructing four-bladed propellers, the laminµ I, I<1> are crossed as shown in Fig. 16, with hub-pieces D, D<1>, D<2>, D<3>, or the modified form shown in Fig. 17 is adopted. The Specification also describes keys o for the laminµ, examples being shown in Figs. 18 and 21. Fig. 28 shows a number of laminµ with keys o, the joints h<4>, h<5>, h<6> being in staggered relationship.

Abstract: 616,360. Copying-telegraphy. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 30, 1946, No. 12996. Convention date, May 2, 1945. [Class 40 (iii)] In a system for the telegraphic transmission of messages, documents, photographs &c. by electro-optical means, an image of reduced dimensions compared with that transmitted is formed at the receiver on a film of high sensitivity and is utilized for the projection of an enlarged image on a relatively slow printing paper. The reduced image is preferably formed on a positive film and the printing may be effected on heliographic paper with the use of a high-pressure mercury lamp. The recording of an image may be performed in a period of approximately 8 secs. with a band width of 80 to 100 kc/sec. and the period allowed for printing may be 16 or more secs.-a number of reduced images being printed simultaneously.

Title: Machine for welding the longitudinal seams of tapered tubes
IPC: B21C37/18
Filed: 1929-12-09
Abstract: 350,495. Making tubes, posts, &c. DEHN, F. B., 103, Kingsway, London.- (Union Metal Manufacturing Co. ; 1432, Maple Avenue, North East, Canton, Ohio, U.S.A.) Dec. 9, 1929, No. 13021/31. Divided on 350,486. [Classes 83 (ii) and 83 (iv).] Drawing; drawing-dies; ; uniting by fusion.-In a machine for welding the longitudinal seams of tapered tubes, which may ultimately be converted into sheet metal posts, tubular expansible dies are used and are yieldingly held in engagement with the pre-formed tube as it is drawn through. The curved sheet s, Fig. 4, with an open seam is passed from the bending machine to the draw-bench c and enters a bell 97 to which are pivoted at 102, four dies 99, 100, 101, the lower die being stationarily supported by a bracket 109 whilst the upper die 99 is pressed downwards by a fluid pressure cylinder 106 pivoted thereto at 108. The lower and upper dies carry coacting V-shaped guides 113, 114, Fig. 3, respectively, which engage the free ends of the dies 101 and restrain their opening. The interior surfaces of the dies at the end where the tube emerges therefrom may be curved as shown to approximately the intermediate curvature of the finished tube or may be flat. The tapered tube is drawn through the dies by means of a drawbar clamped thereto, a longitudinal slot 110 in the lower die accommodating the bar and clamp. To prevent the edges of the tube from overlapping, the upper die is provided with a longitudinal rib 115 merging into a tapered rib 116, Fig. 8, carrying a lower inclined flange 117 which causes the edges to come together in the correct positions above an anvil 119 where they are fusion welded by means of an electric arc or a torch 118. On entering the bell 97 the edges are maintained level by means of two rollers 138a, Fig. 1, carried by a bar 139a vertically movable on pillars 141a. Links 143 connect the bar 139a to levers 144 pivoted to supports 145 and loaded with adjustable weights 146. The levers 144 may also be operated by hand and may be locked under clips 147 to maintain the rollers in the elevated position when not required. Instead of the V-guides 113, 114, each die may be pressed against the tube by means of a separate fluid cylinder or by mechanical means which allow the dies to expand and conform to the diameter of the tube. The draw-bar is hooked to a chain 122, Fig. 10, which is driven from a motor through a belt drive 135 and either the belt 130, clutch 128, and worm reduction gear 125, or at a slower speed through a reduction drive 133, belt 140, reduction gear 127, clutch 128 and further reduction gear 125. The edges of the sheet blank are thickened by a cold-rolling operation to facilitate welding. Specification 350,486 is referred to.

Title: Improvements in electric control systems
IPC: B61L3/12
Filed: 1930-07-07
Abstract: 358,587. Track apparatus for stopping trains. STEVENS, R. J., Dunoon, Coombe Lane, Kingston Hill, Surrey. July 7, 1930, Nos. 13383/31 and 13384/31. Divided on 358,516. [Class 105.] The motor of a Dieselelectric locomotive is supplied from a Ward-Leonard generator, the field of which is in circuit with a thermionic valve for control thereby. The grid potential of the valve is varied by an iron shield manually movable between the primary and secondary of a transformer to alter the coupling therebetween and so to vary the secondary voltage, the swing of which is applied to the grid. An iron plate 56, located at the side of the track, may be raised from a signal-box, so that as the locomotive passes, it projects between the primary and secondary of another transformer suspended under the locomotive. The coupling between the transformer windings is thus reduced so that the grid swing of another valve is also reduced and this causes the locomotive to slow down to a creeping speed. A second shield on the track causes the brakes to be applied fully and the locomotive brought to rest.

Title: Monitoring system for machine tools
IPC: G05B19/048
Filed: 1977-03-31
Abstract: The machining apparatus has movable members (20, 120), the movement of which is monitored by limit switches (24, 25, 124, 125). Control devices (17, 117) control these movable members. To monitor the function of individual operations and movements, first monitoring units (34 to 37), e.g. signal lamps, are connected to a control means (11, 12, 26) for the automatic machining operations. The first monitoring units (34 to 37) are thus actuated by the individual machining operations or are illuminated. Second monitoring units (38, 39), which, for example, can likewise be designed as signal lamps, are connected to the control devices (17, 117) and are actuated by them. By a spatial allocation in accordance with the functional relationship between first and second monitoring units, it can thus immediately be established, when monitoring units respond, which control device is working or is not yet working during which machining operation. <IMAGE>

Abstract: 135,845. Rochefort, F. Nov. 22, 1918, [Convention date]. Movable-abutment type; cooling parts; working- fluid supply.-A rotary four-stroke internal-combustion engine of the geared-vane type comprises a number of pairs of curved cylinders C<1>, C<2> adapted to rotate at a uniform speed and to cooperate with rigidly interconnected pistons p<1>, p<2>, which are geared by links B, B<1>, rollers R<2>, and fixed cam-tracks K to rotate with the cylinders, but alternately fast and slow. Cam-operated valves S admit air to the rotating cylinders, where it is compressed by the piston until the temperature is sufficient to ignite the combustible vapours, which are injected gradually into the cylinder by cam-operated pumps. Expansion then takes place until 'the exhaust ports L are uncovered by the piston, and the gases escape through an exhaust pipe w arranged so as to utilize their reaction.. The valve S admits a scavening-charge of cold air, part of which escapes through the ports L, and part of which is forced back past the valve S by the advancing piston. While one piston is ex. hausting hot air, the opposite piston is compressing. A fixed casing V surrounds the rotating cylinders, which circulate air for cooling. A series of cylinders may be arranged co-axially.
