Title: Improvements in composite material and shaped bodies thereof
IPC: C22C33/02
Filed: 1947-01-27
Abstract: A composite metal article comprises a matrix of compacted powdered ferrous metal having intercommunicating pores and a cuprous metal filling the pores, characterized in that the ferrous matrix contains up to 1.7 per cent of combined carbon and forms 70-90 per cent by volume of the article and the matrix and infiltrant metals are alloyed with each other by diffusion heat treatment, e.g. at 500 DEG to 900 DEG C.  The matrix may thus contain cuprous metal in solution and the infiltrant may contain ferrous metal in solution as a result of quenching the material, e.g. from at least 835 DEG C.  This dissolved metal may be precipitated, e.g. by heating at between 315 DEG  and 650 DEG C.  The material may contain alloyed additions of phosphorus, manganese, nickel, chromium, silicon, vanadium and/or titanium introduced with either the infiltrant metal or the matrix. Thus the infiltrant metal may contain up to 2 per cent of manganese which ensures that any residue remaining outside the matrix is fluffy and easily removed.  The infiltrant metal may also contain 2-5 per cent of iron.

Title: Improvements in conveying apparatus
IPC: B65G33/04
Filed: 1922-01-27
Abstract: 186,300. Nielsen, R. Sept. 21, 1921, [Convention date]. Screw elevators.-Packages 6 are delivered singly to the upper end of a rotating helical platform 28 and are prevented from rotating with the platform by stops 39, 40 so that they are lowered as the platform rotates. The platform 28 is carried by arms projecting from a vertical shaft 20 rotated at a comparatively slow speed and geared at the upper end to a shaft 13 carrying a cam 12 which effects the reciprocation of a cage 10 carrying one package 4 once during each rotation of the platform, the timing being such that the upper part 29 of the platform comes between the rollers 9 and removes the package 4 during the continued descent of the cage. A pivoted stop 8, Fig. 3, at the end of an ordinary inclined roller conveyer is withdrawn by a tappet 46 on the cage to permit the passage of another package to the cage. When a package in the cage is not in position to be removed by the platform, a latch 50 remains in alignment with a stop 52 on the floor 7, and the descent of the cage is arrested. This latch is moved out of the path of the stop when the package is correctly positioned. The rotation of the shaft 20 is so timed that the lower part 30 of the platform moves between sets of rollers 31, 32 at the upper end of a roller conveyer at the time when a package is in position to be removed at the lower end.

Title: Improvements in devices for transforming a reciprocating linear motion into a rotarymotion and in particular in devices of this kind for actuating a rotating element ofa cartridge magazine or a belt feed mechanism in an automatic firearm
IPC: F16H31/00
Filed: 1952-01-31
Abstract: 696,354. Cartridge feed mechanisms. BREVETS AEROMECANIQUES SOC. ANON. Jan. 31, 1952 [Feb. 19, 1951], No. 2638/52. Class 92(ii) [Also in Group XXIV] Relates to mechanism for transforming a reciprocating linear motion into a uni-directional rotary motion, and in particular to the ammunition feed mechanism of an automatic firearm. According to the invention the reciprocating part 1, Figs. 1 and 2, actuates a reciprocating member 3 carrying a freely rotatable pinion 4, this pinion being in mesh 'with pinions 9, 10 located on either side of it and subjected to the action of unidirectional stopping means, such as pawls 19, 20, means being provided for coupling at least one of the pinions 9, 10 to the member 2 to which the unidirectional rotary motion is to be imparted. In the construction shown the part 1 is connected to the member 3 by bellcrank and link mechanism 6, 7, 8. When the member 3 moves upwards the pawl 20 holds the pinion 10 stationary and the pinion 4 drives pinion 9 in an anticlockwise direction. This movement is communicated to the member 2 by the shaft 11 of pinion 9, a ratchet wheel 12, and ratchet 13, the latter together with member 2 being mounted on a sleeve 16 rotatable on the shaft 11. When the member 3 moves downwards the pawl 19 holds the pinion 9, and the anti-clockwise movement imparted to the pinion 10 serves to rotate a pinion 23 through pawl and ratchet mechanism 21, 26 and sleeve 24, the pinion 23 being geared as shown to the member 2. The mechanism enclosed in the broken lines of Fig. 2 may be omitted if the member 2 is to be rotated only by the pinion 9; such an arrangement is illustrated in Figs. 3 and 6 applied to means for accelerating rounds of ammunition towards the the outlet 28a of the magazine 28 of an automatic firearm. In this case a cam surface 1a on a recoiling part 1 causes vertical reciprocating motion of the member 3 carrying the pinion 4 which functions in the manner described above, the part which is given a unidirectional rotary movement being a torsion bar 31 which is keyed to the pinion 9 (not shown), and to tubular shaft fitted with a toothed wheel for engaging the rounds. Specifications 696,350 and 696,353 are referred to.

Title: Electric Switch
IPC: H01H1/16
Filed: 1966-01-20
Abstract: 1,151,331. Toggle switches; roller contacts. WESTWOOD SWITCHGEAR Ltd., and D. W. C. SMITH. 25 Nov., 1966 [20 Jan., 1966], No. 2722/66. Heading H1N. Each pole of a three pole switch has two pairs of opposed fixed contacts, 10, e.g. of copper, the upper and lower pair each being bridged by a roller contact 28, e.g. of copper, and one contact of each pair being connected by a fuse 12 (see Figs. 1, 8). A pair of fixed neutral contacts 13 (Fig. 1) are connected by a link. The fixed contacts are mutually insulated by screens 14. The six rollers 28 are carried by a carriage 20 comprising insulating blocks 22, 22a and screens 23. Carriage 20 has two bosses 35 at each end vertically reciprocatable (perpendicular to plane of Fig. 4) in slots (36, Fig. 9) in the switch housing, thus allowing rollers 28 to break with contacts 10, the blocks 22 moving between contacts 10 to limit arcing. Each roller 28 comprises two parts providing a V-groove to make point contacts with the edge 11 (see Fig. 10) of contact 10. The two parts are urged together by coil springs (30, Fig. 5) around rods (29) supported in blocks 22. The carriage 20 is reciprocated between "make" and "break" by a snap action toggle mechanism comprising a manual bell crank lever 44 coupled to a lever (40, Figs. 2, 3), with an over-centre toggle spring (41) provided at each end of the carriage 20, each lever 40 being coupled to a rockable fork (42, Fig. 9) embracing the lower boss 35. The near fixed contacts (as in Fig. 4) are secured between the screens 14 which are held on fixed bars 51. The bars 54 of the front fixed contacts are releasably latched in the housing. The fixed contacts may be series or parallel connected. The fixed contact may be in two parts spring urged away from or towards one another. The roller may have a rounded edge running in a V-groove in the fixed contact. The roller may be the fixed contact.

Title: Improvements in and relating to engine starter drives
IPC: F02N15/06
Filed: 1933-01-28
Abstract: 406,462. Turning-gear. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Jan. 28, 1933, No. 2751. Convention date, Jan. 30, 1932. [Class 7 (v).] In an engine starter comprising a pinion 11 moving axially on a threaded sleeve 9 driven from the shaft 1 through a coil spring, the pinion is prevented from rebounding towards the driven gear of the engine by a centrifugal element in the form of an eccentrically weighted detent ring or disc 17 loosely surrounding the shaft 1. In one form, Fig. 2, the ring 17 is retained in a groove 18 in the sleeve 9 by a split ring 20. Longitudinal extensions 21 of the pinion teeth are provided with retaining shoulders 19 having a face 22 steeper than the face 23. The ring 17 is normally maintained in its lowest position by gravity, and rides over the face 22 when the pinion 11 is moved axially into mesh with the engine gear by rotation of the shaft 1. When the engine starts and the pinion moves axially out of mesh, the ring 17 rides over the face 23 and is then maintained by centrifugal action in its eccentric position, co-operating with the face 23 to prevent return of the pinion so long as the shaft 1. is rotating. In modifications, (1) the weighted ring slides over the face of a flange on the pinion and is retained by an annular disc and a snap ring ; (2) the ring 33, Fig. 9, is pivoted at 34 on a flange on the pinion and normally urged into latching position by a spring 35 ; (3) a weighted detent member 37, Fig. 12, sliding on a flange 40 on the pinion and controlled by a spring 44 is connected to the flange by pins 39, 41 engaging slots; and (4) a detent ring 52, Fig. 15, is normally centered by a spring 54 and has a peripheral groove 55 for engagement with lugs 58 on extensions 57 of the pinion teeth.

Title: Fluid pressure relief valve
IPC: F15B13/01
Filed: 1962-01-25
Abstract: 981,782. Valves. SHAFER VALVE CO. Jan. 25, 1962 [Feb. 2, 1961], No. 2810/62. Heading F2V. [Also in Division G3] The subject matter is similar to that described in Specification 989,957 but the oscillating piston and rotary valve may be replaced by a double-acting power device 13, Fig. 1, and a gate valve 10. Additionally the lower end of tank 43 is connected by conduits 46, 47 through a valve 48 to the lower end of the device 13 whilst the lower end of tank 45 is connected by conduits 49, 50 through a similar valve 51 to the upper end of the device 13. Each valve 48, 51 is of identical construction and comprises a chamber 56, Fig. 2, with a seat 57 leading to conduit 46 or 49 whilst a movable valve closure 59 coacts with the seat. The closure 59 includes a head of resilient material and a stem 60 passing into a chamber 66 where it is provided with a piston 65, the chamber 66 being open to a conduit 71 or 77 connected to the upper end of tank 43 or 45; the diameter of stem 60 is of greater crosssectional area than that of the part of the head which engages the seat 57. A port 62 in the side of chamber 56 leads to conduit 47 or 50; the closure 59 is urged to the closed position by an adjustable spring 73. The upper part of chamber 66 is vented. If pressure fluid is supplied to a conduit 44, Fig. 1, the oil pressure in tank 45 acts through conduit 49 directly and the closure 59, Fig. 2, to unseat it and permit the air to flow via conduit 50 to the top of the power device. Concomitantly the pressure in conduit 77, Fig. 1, lifts the piston 65, Fig. 2, of the other valve 48 and unseats its closure member so allowing oil from the bottom of the device to exhaust the rough conduits 47, 46, Fig. 1, into the bottom of tank 43. The operation is reversed when pressure is supplied to conduit 41. Should the device 13 be stopped at an intermediate position the valve 48 acts to hold it in that position. If the oil in the device is subjected to extremes of temperature the closure 59 acts on a relief valve in response to pressure variations in chamber 56. A double check-valve 17 is connected across the gate valve 10, Fig. 1, and the supply for the control system is obtained from a point between the check valve elements. A piston 34, which actuates the control valves 20, is moved by pressure in lines 31, 32, which pressure is a measure of the flow in the line controlled by the gate valve; each line 31, 32 embodies a valve 38 for retrieving the pressures on the piston 34 whereby the piston and control valves 20 return to the neutral position after each operation.

Abstract: 545,231. Resorcinol-formaldehyde condensates. SOC. DES USINES CHIMIQUES RHONE-POULENC. March 3, 1941, No. 2846. Convention date, March 4, 1940. [Class 2 (iii)] [Also in Group VIII] For affixing foils of plastic material, having a basis of cellulose acetate, to wood, a product of the condensation of resorcinol and formaldehyde is used as the adhesive. One part resorcinol is dissolved in two parts of a 30 per cent. solution of formaldehyde in water, the temperature is increased to 60‹C. and is maintained at this for 30 minutes. The semicondensate is then applied with a brush to the surfaces to be joined, and these are assembled and placed in a press with heated platens. The pressure should be increased slowly at first and then heat applied to bring about the polymerization of the semi-condensate, the adherence of the plastic material and wood being thus obtained. When the semi-condensate is not to be used immediately 10 per cent. of ethyl acetate may be added thereto.
