Title: Improvements in diesel locomotives
IPC: B61C15/02
Filed: 1963-05-02
Abstract: 1,046,503. Engine turning gear. J. L. GRATZMULLER. May 2, 1963 [May 10, 1962], No. 17402/63. Heading F1K. [Also in Division B7] In a diesel locomotive an auxiliary diesel engine 6 drives a generator 7 feeding a electric motor 8 capable of exerting sufficient tractive effort to start and accelerate a train to a speed at which a main diesel engine 1 can propel the train through a mechanical transmission without a slipping clutch being provided. As shown, the electric motor 8 is coupled by reduction gearing 10 and a free wheel 11 to the crankshaft of the main engine 1, which drives the locomotive wheels through a gearbox 2 and reversible gearing 4. The electric motor 8 thereby serves whilst starting the train to rotate the main engine 1 idly until fuel is supplied and then to start the main engine 1, which may be preheated by cooling water from the auxiliary engine 6. The generator 7 also feeds a circuit 13 supplying the ventilation and lubrication services of the locomotive and a circuit 14 for the train heaters, automatic or manual .switches preventing simultaneous feeding of both motor and heaters to prevent overloading of the generator 7. In another embodiment the electric motor 8 is connected by a chain drive to the shaft connecting the main engine 1 to the gearbox 2, a free wheel being interposed between the chain drive and the engine 1 so that the engine 1 is not rotated when the electric motor is driving. The locomotive may include more than one main diesel engine.

Patent GB-257380-A (GB)
Title: Improvements in horns or warning devices of the diaphragm type
IPC: G10K9/10
Filed: 1925-07-08
Abstract: 257,380. Griffiths, T. L. July 8, 1925. Diaphragm horns.-A warning horn has a series of spring hammers and a rotatable cam for retracting the hammers and subsequently releasing them to strike the diaphragm, or equivalent sounding member. As shown in Fig. 1, a number of hammers 5 are pivoted in radial slots in a ring 3 and are pulled towards the diaphragm 7 by springs 8. Teeth like cams 16 on a rotatable back cover plate 13, Fig. 4, engage tail pieces on the hammers so that when the cover is rotated the hammers are caused to strike the diaphragm 7 by being first retracted and then suddenly released. The number of cams is unequal to the number of hammers so that the hammers are operated in succession. The rotatable cover 13 is provided with three handles 15 so that one handle is always in a convenient position for actuation. In the construction shown in Fig. 10, spring hammers 42 are retracted by a central cam 31 rotated by a crank 37 through a free-wheel or ratchet clutch. The hammers are supported against lateral movement by arms 45. The cam may be operated by an electric motor instead of by hand.

Title: Improvements in and relating to resinous condensation products and methods of preparing the same
IPC: C08L67/00
Filed: 1927-07-01
Abstract: 273,748. British Thomson-Houston Co., Ltd., (Assignees of Adams, L. V.). July 1, 1926, [Convention date]. Adhesives.-The condensation of a polyhydric alcohol with an aromatic polybasic acid or its anhydride is carried out rapidly to produce a product in the heat-hardened or insoluble-cold condition (C stage), and the product is ground ana treated with a liquid or a material liquefiable at the treating temperature until complete solution occurs. Suitable treating liquids comprise glycol diacetate, diethyl phthalate, acetone oils, benzyl alcohol, acetate or benzoate, toluidine, cresol, tricresyl phosphate, triacetin, anisol, o-cresyl benzoate, ethyl lactate, indene, and indene polymer, or low boiling solvents such as acetone may be employed. In an example a glycerine-phthalic anhydride resin is heated for 36 hours at about 170 C. with one of the above liquids in a closed container. The product, whose viscosity may be varied by partial or complete vaporization of the solvent or by thinning with acetone &c., may be used as an adhesive. Oils, gums, natural and synthetic resins, asphalt and cellulose derivatives may be incorporated with the solution. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention may be applied to other synthetic resins, such as resins of the phenol-aldehyde and urea-aldehyde types, and in connection with urea-aldehyde resins, diphenyl amines, toluidine, pyridine or other amine compound are mentioned as suitable solvents. This subject-matter does not appear in the Specification as accepted.

Title: Physiological fluid pressure measuring apparatus
IPC: A61B5/021
Filed: 1963-05-03
Abstract: 982,632. Physiological fluid pressure measurement. E. I. DU PONT DE NEMOURS & CO. May 3, 1963 [June 21, 1962], No. 17560/63. Heading A5K. Apparatus for measuring the pressure of physiological fluids in the body comprises an apertured body-membrane depressor element 11, a rigid displaceable foot 15 freely slidable in the aperture 12 and having its body-contacting surface disposed inwardly from the bodycontacting face of the depressor element by a distance equal to the non-variant distance which the flesh intrudes into the aperture when stressed by the depressor element and an electric transducer responsive to displacement of the foot for measuring the fluid pressure as a function of the displacement of the foot. The membrane-contacting surface 16 of the foot 15 is set behind the membrane-contacting surface 17 of the depressor element 11 to compensate for errors in measurment arising from the intrusion of the membrane into the aperture 12 in the depressor element 11. The foot and depressor element are made of polymeric material and the foot is supported in the aperture by a metal spring 18 which electrically interconnects a lead 24 with a conducting strip 31 stretched across the near side of the foot. A curved resistive strip 35 on a support 36 contacts the conducting strip and is connected to a second lead 46, the circuit being completed by a battery 21 and a microammeter 26. In use the foot is displaced in dependence upon the fluid pressure beneath the body membrane against which the surfaces 16, 17 are pressed. This varies the area of contact between the conducting and resistive strips so that the total conductance and thus the current in the circuit varies to give a measure of the fluid pressure under test. In alternative constructions (not shown), the displacement of the foot varies the capacitance in an alternating current circuit, the reluctance in a magnetic circuit, the induction of a transformer or the amount of light reflected to a photo-electric cell by a mirror on the rear of the foot. Specification 982,633 is referred to.

Title: Improvements in method and apparatus for assembling receptacle parts
IPC: B21D51/26
Filed: 1935-06-20
Abstract: 445,817. Making tins &c. CROAD, A. K., 70, Chancery Lane, London.-(American Tobacco Co. ; 111, 5th Avenue, New York, U.S.A.) June 20, 1935, No. 17718. [Class 18] Receptacles or tins in which two parts, one of which may have a hinged lid, are assembled by telescoping one within the other, have the parts fed in the relative positions shown in Fig. 15 by pushers 47, one of which has an inclined face 51, a ram A inserting the forward edge of the tilted part into the other, after which continued movement of the ram aligns the two parts by the engagement of a roller 83 with a fixed abutment 84, thus canting a platform 81 and thereafter presses the parts together until the two beads shown engage. The parts are fed intermittently by gravitation in pairs down a shoot C, Fig. 6, and are then moved along a table 20, by feeders 47 which are secured, with lost motion by a spring bolt 48 to a reciprocating slide 50, Fig. 11. The two receptacle parts are then pressed into engagement and thereafter pivoted dogs 128 on slide 50 eject the receptacle on to a receiving table 136. The intermittent feed from shoot C' is effected by pivoted dogs 25, Fig. 25, actuated by wedges 30, Fig. 27 to release the lowermost pair while the remainder are held, a plate 31 carrying the wedges being reciprocated by the engagement of an inclined surface 45 on a reciprocating bar 44 carried by the feeders 47, with a roller 41 on an arm 39 pivoted at 40 and connected with a link 36 secured to the plate 31. The slide 50 is reciprocated by a connecting rod 60<1> driven by gears 61 from the main shaft 141. The dogs 128 for ejecting the cans are retracted and projected by frictional engagement of a bar 133 engaging the tails of the dogs with a bar 120, Figs. 11 and 13, an extension 122, Fig. 7, on which is resiliently engaged by a plate 123. When slide 50 begins to move from left to right from the position shown in Fig. 6, owing to the frictional drag on bar 120 this begins to move later than the slide 50 so that the dogs are rocked to engage behind the cans. At the other end of the path of the slide 50 the bars 120 are contacted by stops 137 and pushed back so that reverse movement of the slide retracts the dogs. The rams A, B, Figs. 5 and 15 are actuated respectively by gears, cranks and connecting rods indicated at 75, 73, Fig. 5, from the main shaft 121. The cam is held during actuation of the rams by a fixed plate C, Figs. 16 and 18, having inclined surfaces 85, 86 for supporting the two can halves, and a movable holder D, Figs. 5 and 16 reciprocated by means of a bell-crank 99, Fig. 2 and a connecting rod 102 actuated from a cam slot 108. The member D also carries a rod 112 which resiliently contacts a plate 91 pivoted to member C so that a part 95 grips the can.
