Title: Improvements in or relating to locomotives tractors or the like
IPC: B61C17/12
Filed: 1932-02-16
Abstract: 386,457. Controlling motor vehicles. RENAULT, L., 8, Avenue Emile Zola, Billancourt, Seine, France. Feb. 16, 1932, No. 4614. Convention date, April 17, 1931. [Class 79 (v).] In locomotives, tractors, and the like driven by internal-combustion engines, engagement of the main clutch is facilitated by automatic means controlling the fuel supply so as to ensure that the driving and driven elements of the clutch are always in synchronism, further means providing that the members of the variable-speed gear are necessarily in synchronism before they are brought into engagement. The engine 1 is connected by a clutch 2 to a changespeed gear 3 driving a shaft 4. The engine shaft and the driven clutch shaft 6 are connected by gears 10 .. 13, one comprising a friction coupling, to shafts 8, 9, Fig. 3, one screwed and the other splined to engage a rack 14 engaging a sector 15 controlling the fuel pump or carburetter 19 of the engine by a link 18. Except when the engine shaft and the shaft 6, and thus the shafts 8, 9, are running in synchronism, end movement of the rack 14 to control the engine speed and secure such synchronism is produced. For the synchronizing-means 14 &c. may be substituted differential gearing or centrifugal means. Hand control 20 for the fuel is provided.

Abstract: 1389211 Inspecting fruit on a conveyer D K ALEXANDER 15 Feb 1972 [16 Feb 1971] 4716/71 Heading B8A Fruit 1 on an endless conveyer (seen in diagrammatic cross-section in Fig. 2) is inspected by viewing the passage of its image on a screen 4 as the fruit is rotated. The results may be entered on a keyboard 10. The information is thus passed into a magnetic tape 6 via a recording head 7. A reading head 8 controls subsequent routeing of the fruit. Separate operators sitting along the conveyer may be used to view respective lanes of fruit. Alternatively there may be an additional mirror 2<SP>1</SP> (Fig. 3, not shown) so that two lanes may be viewed simultaneously. The viewing screen 4 may be formed with grid lines to enable specific areas of the fruit to be identified. The screen 4 may be mounted so as to move along a limited distance at the speed of the conveyer (Fig. 4, not shown). There may be a scanner which responds to colour &c. of the fruit in a series of lanes of the conveyer (Fig. 5, not shown), and passes information to devices which cause a redistribution of the fruit in different lanes. A weigher may cause further selection. The keyboard may be mounted on a conveyer (kc) (Fig. 6, not shown) which is mounted adjacent the main conveyer. The keys may operate reed switches or Hall effect devices and may be connected to a memory. The conveyer may be of the kind described in Specification 1,176,396. The fruit may engage rods 96 thereby causing scanning deflection of mirrors 92.

Title: Improvements relating to metal working presses
IPC: B21D24/02
Filed: 1932-02-18
Abstract: 388,566. Cupping- presses. FITZPATRICK, H. D., 94, Hope Street, Glasgow.-(Marquette Tool & Manufacturing Co.; 6500, West 65th Street, Chicago, U.S.A.) Feb. 18, 1932, No. 4786. [Class 83 (iv).] A metal-working press comprises an upper reciprocating ram and a pressure pad whose movement is yieldingly resisted by a fluid-pressure cushion having a controlling valve which is normally held on its seating by fluid pressure, until this pressure is overcome by pressure in the cushion. In a double acting press, a ram 13 carrying a die 21 is reciprocated by links 17 connected with a crank shaft 15 while a co-operating central die 20 is connected by link 19 to a second crankshaft 18. Mounted on the base 10 is a baseplate 23 which supports a die 24 enclosing a second die 25 which rests on a pin 26 supported on a pressure member 27 connected to the piston 28 of a hydraulic cylinder 29. A valve casing bolted to this cylinder is provided with a valve 36 controlling the flow between the cylinder and a pipe 45 leading to a pressure reservoir 43 to which air or similar fluid pressure may be admitted from a pipe 47 through a pressure regulating valve 48. Fluid from a branch from the pipe 47 also flows along a pipe 52 to a valve casing 54a and thence through a pipe 42 to a cylinder 40 having a piston 39 connected to the valve 36 which is normally held on its seating by the pressure in the cylinder 40. The stem of valve 36 also carries a piston 38 of a diameter intermediate between the diameters of valve 36 and piston 39. The hydraulic pressure in the pipe 45 acts on the piston 38 to tend to open the valve against the normally greater seating pressure of the piston 39. The cylinder 40 is controlled by a pair of automatic valves 56, 59 mounted in the casing 54a and actuated through a rocker 70 from a cam 68 on a member 67 driven by a chain 73 from part of the main driving gearing 22. When valve 56 is opened the pipe 42 leading to cylinder 40 is open to the fluid pressure in the pipe 52 but when valve 56 is closed and valve 59 is open the pipe 42 is in communication with a passage 61 open to the atmosphere. The valve 36 can then be unseated by the hydraulic pressure on the piston 38. In operation during the approach of the ram to the work the parts are in the Fig. 1 position, the valve 36 being seated by the adjustable pressure in the cylinder 40. As the die operates on the work the piston 28 is forced downwards and the increasing pressure finally opens valve 36 and liquid escapes through the pipe 45 to the container 43. When the ram ascends the reservoir pressure on piston 38 opens the valve 36 and restores the piston 28 to its upper position whereupon the valve is seated by pressure admitted to the cylinder 40.

Filed: 1943-03-29
Abstract: 572,576. Sound deadening in buildings. JACOBSON, V. March 29, 1943, No. 5046. [Class 20 (ii)] An acoustical construction adapted to be placed in the path of sound waves issuing from a factory or a testing:house for internal combustion engines so as to absorb and dissipate the sound, comprises a stacked mass of porous blocks assembled to form confined non-planar passages for the passage of the sound. In one example Fig. 1, the blocks 4 of porous material are provided with tapered edges, which, when the blocks are erected on supports such as 1, form recesses 6 disposed in a direction along the height of the wall; these recesses and the apertures 7 in the blocks break up the sound waves and cause dissipation. The blocks may have sides which taper and may be superposed to form ledges 13 facing upwardly, or downwardly, or in both directions as shown in Fig. 6. The blocks may be of cruciform section and the vertical faces may be tapered to form ledges when they are superposed, the blocks also having vertical aligning apertures which can be left hollow or filled with sound absorbing material The superposed blocks having tapered side faces, may be provided alternatively with long and short wings so that when superposed passages 21, Fig. 10, at right angles to the main vertical passages between the blocks may be provided, the projecting ends of the wings being recessed at their edges to receive the supporting angles 20 for the projections. The blocks may be hollow with internally and externally inclined vertical faces so that when superposed in directions at right angles vertical and horizontal connected passages are formed to dissipate the sound. The vertical edges of the hollow blocks may be provided with projections 26, Fig. 16, which abut to form hollows 27 between the blocks and internal ledges inside the passages. The blocks may be of hexagonal section or polygonal section to form main channels and subsidiary vertical channels 31, Fig. 19. between the blocks; and the blocks may have vertical faces which taper inwardly from each end toward the centre and be provided with internal end and central ribs 35, 36, Fig. 21 respectively.

Abstract: 1361174 Helicopter rotor blade UNITED AIRCRAFT CORP 1 Feb 1973 [14 Feb 1972 19 July 1972] 5081/73 Heading B7W A helicopter rotor blade has a spanwise tubular spar 10, an outer skin 12 and rigid fluidimpervious filler material 14 between the spar and the skin, and an indicator (16), Fig. 2 (not shown), for indicating a change in pressure in the spar, and there are sparwise extending channels 17 located in the filler material and in communication with the outer surface of the spar. These channels communicate with a cap (18) at the blade tip which is vented to atmosphere through a spring valve (19), so that if a crack develops in the spar, gas therein may leak to atmosphere so that a pressure drop is registered. The channels 17 are formed by placing a resilient tube (20), Fig. 3 (not shown), against the spar before filling the skin with the filler and withdrawing it when the material has hardened; alternatively channels may be formed by strips of sheet material (22), Fig. 4 (not shown), bonded to the spar. In a further embodiment, spar 110, Fig. 6, is covered by a plurality of blankets 118 each consisting of a sheet (122), Fig. 8 (not shown), either having ribs (124) attached, leaving channels (135), Fig. 7A (not shown) between, or in which channels (135) are cut. The sheets (122) of adjacent blankets overlap, but the ribs do not abut, so that oblique transverse ducts 125 are formed, connecting the spanwise channels (135) with a spanwise duct (120), Fig. 7 (not shown), at the trailing edge of the spar 110. The aft part of the blade is filled with honeycomb material 114 which is perforated so that adjacent cells communicate with one another and with the duct (120) so as to form a sump for gas leaking from the spar so that a pressure drop may be indicated by indicator 116 in the event of a crack in the spar.

Abstract: 466,051. Television. GENERAL ELECTRIC CO., Ltd., EDWARDS, G. W., and ESPLEY, D. C. Feb. 21, 1936, No. 5284. [Class 40 (iii)] During scanning by a disc 11, of which a plurality of revolutions are necessary for a complete cycle of the scanning apertures 1..405, which, during different revolutions of a cycle, are not in the same relation to a fixed system when a synchronizing signal is to be emitted, synchronizing signals are generated by slots 1 .. 405 in the disc which co-operate with a fixed slit 17 in a relationship which is varied cyclically during the scanning cycle. The synchronizing slots are distributed similarly to the scanning holes, and the spiral to be effective is chosen by a slot 16 in an intercepting disc 15. According to modifications : the slots are on a circle, and the one to be effective is chosen by apertures in a disc, whose radius is n times the radius of the scanning-disc and which rotates with 1/n of the angular velocity of the scanning-disc, where n is the number of revolutions in a complete scanning cycle, Fig. 3 (not shown) ; the number of slots is, as nearly as possible, equal to N/n where N is the number of scanning- apertures, and the slots co-operate with different fixed slits, of which one is selected by an intercepting disc, Fig. 4 (not shown) ; the slots co-operate with slits in a disc, whose speed of rotation is less than <1>/100 of that of the scanning- disc, Fig. 5 (not shown). A framing signal of less frequency than the line-synchronizing frequency is generated by blocking one or a few of the synchronizing slots. Alternatively, slots, which are different from the line-synchronizing slots but co-operate with the same photoelectric cell, are exposed during some revolutions of the scanning-disc, Figure accompanying Complete Specification (not shown).
