Title: Improvements in or relating to time stamps
IPC: G07C1/06
Filed: 1931-05-08
Abstract: 378,893. Time recorders; ink-ribbon mechanism. INTERNATIONAL TIME RECORDING CO. OF NEW YORK, Endicott, New York, U.S.A.-(Assignees of Bishop, L. C. ; 58, Taft Avenue, Lynnbrook, and Sprecker, A. L. ; 30, Elinor Place, Freeport, both in Long Island, New York, U.S.A.) May 8, 1931, No. 13702. Convention date, May 20, 1930. [Classes 100 (ii) and 100 (iv).] A time stamp comprises a platen 32 connected by a rod 34 to the movable core 35 of an electromagnet 37. An operating switch 63 is connected by links 54, 65, 50 to a block 76 operating contacts 77, 78 in the supply to the electromagnet. Movement of the switch makes the circuit and the armature 45 is attracted to core 39, causing the arm 50 to be raised and a latch is released whereby the contacts 77, 78 are opened. The electromagnets 81 are energized once each minute by an electrical impulse and the armature 84 is connected through the bell crank 89 to the pawl 96 on the ratchet wheel 99 and also to the lever 94 actuating the ratchet mechanism of the clock face. The wheel 99 is carried by the shaft 90 upon which is mounted the wheel 100 gearing with wheel 101 secured to the minute wheel 102. The minute, hour, day, and month wheels are geared together by cam-and-ratchet devices whilst the year wheel is fixed by hand. A bell crank 143 is connected at one end to the moving core 35 and at the other to a lever 144 pivoted to a T-shaped piece 145, which is pivoted to levers 147, 148. A lever 149 is pivoted to the lever 148. The ends of lever 147 form ratchet pawls and those of 149 retaining pawls of the reels 150, 151 of the ink ribbon reels. A projection 158 of the lever 149 is connected by springs 155, 157 to the pin 156 and the bottom of the member 145 respectively. The movement of the lever 144 causes one reel to be actuated and when the ribbon is unwound the lever 144 turns the member 145 in one direction or the other to bring the ratchet mechanism of the other reel into operation to rewind in the other direction. Other printing matter is formed on members 191 which may be turned from outside the casing, an indicator being provided. Specification 236,199, [Class 139, Watches &c.], is referred to.

Title: Thermal method and system of magnetic recording
IPC: G11B11/115
Filed: 1959-04-22
Abstract: 916,764. Cathode-ray storage tubes. GENERAL MILLS Inc. April 22, 1959 [April 22, 1958], No. 13734/59. Class 39 (1). [Also in Group XIX] Information is recorded on a magnetic film or strip by first uniformly pre-magnetizing the film transversely, and then locally heating discrete areas above the Curie point so that when cooled the magnetization in these areas is reversed. Fig. 2 shows magnetic film 26 (which may be an evaporated MnBi or MnAs film about 1,000 .U. thick), on a glass or like substrate 28, which has been pre-magnetized to make the upper surface of N polarity and subsequently heated at 74, 76, 78 to produce the pattern shown. Fig. 3A shows schematically an electron discharge tube and its control circuitry for read-in-the read-out circuitry (Fig. 3C, not shown) is similar-where the local heating of the magnetic film 96 is effected by unblanking an electron beam from gun 88. An electromagnet 102 pre-magnetizes film 96, and an electrically energized resistive coating 100 allows its preheating (where necessary) to a temperature just below the Curie point. For read-in the beam is accurately focused by coils 92 and 112 to produce a spot on the film 190 and the spot is moved across it horizontally by a sawtooth generator 138. The beam is normally blanked off by modulator 182, but signals act to unblank the tube and reverse the magnetisation of film 96 at the corresponding point. For read-out the positive voltage applied to the film is replaced by a negative voltage from a read-out switch, the electron beam is de-focused so as to cover the whole film and permanently unblanked by a signal, and an " image " of the film is formed in the region of a detector 114 (Helmholtz deflection coils 120 mounted each side of the tube causing the electrons to be deflected in the reverse direction after they are " reflected " from the negatively charged film). This image is deflected by a sawtooth generator 226 similar to unit 138 over detector 114.

Abstract: 358,070. Light current relays and electromagnetic switches. RAY, F. I., Parkminster, Bushey Hall Road, Bushey, Hertfordshire, and BIDDLECOMBE, A. W., Bramshaw, Boleyn Gardens, West Wickham, Kent. May 5, 1930, No. 13763. [Class 38 (v).] In order to ensure a steady retractive movement without an appreciable time lag of the armature of a D.C. telephone &c. relay a thin plate 15 of non-magnetic material such as copper is mounted on the relay core adjacent the polepiece 6 and extends to the yoke piece 3. The action of the induced-currents in the thin copper plate 15 is to diminish oscillatory movement and to prevent any temporary re-attraction of the armature during the releasing movement but is not sufficient to slow down appreciably the time of release. In order to prevent vibration or irregular action of the contact springs, the springs which are left out of contact after the completion of the armature movement are supported by being provided with side wings which engage with the side recesses of an insulating block 10 which may be of the form shown in Fig. 8, and which may be painted white to enable the working of the springs to be observed with ease. The plate 15 may extend only half-way over the core and winding, Fig. 3, and as shown in Fig. 6, the plate 15 is moulded into the coil cheek 14a. The armature 5 is held on the knife-edge 4 formed at the end of the L-shaped yoke 3 by a spring-loaded washer surrounding a screw 16.

Title: Improvements in or relating to pick-off devices for gyroscopes
IPC: G01C19/28
Filed: 1942-10-01
Abstract: 560,472. Electric signalling systems. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MOSS, E. B. Oct. 1, 1942, No. 13811. [Class 40 (i)] [Also in Groups XX and XXIX] Relates to pick-off devices for detecting or measuring movement of the spin axes of gyroscopes (preferably other than air-driven), and of use for operating erecting devices in free gyroscopes or for operating a rate-of-turn or other indicator, or for operating a control. According to the invention, the pick-off comprises two devices influenced to a varying degree by the air disturbance resulting from deflection of the gyro rotor. As shown in Fig. 1, a rate of turn gyro driven electrically or by air jets has a parabolic periphery which, on deflection, varies the air pressures in two Pitot tubes 10, 11 communicating with opposite sides of a diaphragm 6 arranged to operate the controlled mechanism. In a modification, Fig. 2, the air picked up by the two tubes is directed on to two resistance wires 14, 15 enclosed in casings 20, 21 and arranged in a Wheatstone bridge. The casings are connected through a restriction 23. Baffles 28 prevent back-flow influencing the resistance wires. Any tilt of the gyro rotor 13 varies the amount of air flowing past the two resistance wires, and the cooling effect varies the resistance so as to give a right or left indication on an instrument 19. In a further modification, Fig. 3 (not shown), the air flow, instead of influencing the resistances 14, 15 is led by branch pipes to influence resistances 16, 17 in the other arms of the bridge and thence to reservoirs. In this case the rate of rate-of-turn is indicated. In a further modification, the flow is led past all four resistances to afford an indication of the combined effect of the rate of turn and the rate of rate-of-turn. In a further modification, the Pitot tubes are dispensed with, the resistance wires being placed directly in the air stream.

Title: Improvements in firing mechanism for pyrotechnic devices
Inventor: SCHERMULY ALFRED JAMES
IPC: F42C7/12
Filed: 1951-06-12
Abstract: 685,981. Pyrotechnic devices. SCHERMULY PISTOL ROCKET APPARATUS, Ltd. Oct. 31, 1951 [June 12, 1951], No. 13876/51. Class 9(ii) Firing mechanism for pyrotechnic devices such as signal flares comprises a cylindrical member 1 with a forward recess 2 accommodating a detonator holder 21 and communicating with a longitudinal bore 3 in which is a spring-pressed firing pin. In a transverse bore 5 is a pushbutton slide 9 which holds the firing pin 16 in the retracted position. The inner end of the slide has a flange 10 engaging a shoulder 6 in the bore 5 to limit outward movement of the slide, while a pin 13 extending through a bore in the member 1 co-operates with a slot 12 to limit inward movement and prevent rotation of the slide which is held, prior to use of the pyrotechnic device, by passing a split pin 27 through a bore 15 in its outer end. The member 1 has an annular groove 8 into which the casing 25 of the device is cannelured. On removal of the split pin, the slide 9 is pushed inwards bringing an aperture 11 into adignment with the bore 3 and thus releasing the firing pin, the point 20 of which extends into a groove 14 in the slide which rests against a flange 18 of the pin. This flange is cut away at 19 to prevent the formation of an air cushion which would impede movement of the firing pin. The firing mechanism is assembled by first placing the slide in its bore, inserting the transverse pin 13 and then placing the holder 21 containing a" detonator 24 in position. The member 1 is then placed in the casing and the slide caused to move outwards so that the pin 27 can be inserted. An explosive charge is placed in the casing and above it a signal, the casing then being closed by a cap. The firing pin with its spring 28 is then inserted and the bore 3 closed by a retaining screw 29.

Title: Air brakes
IPC: B60T15/14
Filed: 1975-06-23
Abstract: 1514163 Railway air brakes DAVIES & METCALFE Ltd 23 June 1975 [29 March 1974] 13959/74 Heading F2F Pneumatic control means are controlled electronically to produce a pressure overcharge of predetermined pressure and duration in a rail vehicle brake system in which the air pressure in a train brake pipe 34 is reduced to apply brakes. In the system in Fig. 1 having a main reservoir pipe 5 at say 7 bar pressure and a triple valve 2 connected to a control line 14, an exhaust outlet 22 and the reservoir and brake actuator pipes 5 and 34, for nomal brake released running control pressure at say 5 bar is supplied through the pipe 14 to a chamber 12 below a diaphragm 13 of the triple valve which remains in equilibrium when the train pipe pressure is also 5 bar. To apply the brakes the control pressure is selectively reduced to between 5 and 3À5 bar in the pipe 14 and chamber 12 displacing the diaphragm 13 and hollow valve stem 19 downwardly to connect the actuator pipe 34 to atmosphere through the stem 19 and the outlet 22, until the diaphragm 13 is again balanced in its central position. To create a pressure overcharge a push-button PB1 or PB2 of a respective brake controller is pressed energizing an electro-valve 52 to charge a reservoir 28 at an increased train pipe pressure through pipes 53 and 27 and a one-way valve 53A. An electro-valve 26 in line 25 is also open permitting pressure to rise in a chamber 23 below a second diaphragm 18 of the triple valve 2 raising the stem 19 until a new equilibrium pressure of say 5À4 bar is attained in the actuator pipe 34 and the reservoir 28. The raised pressure is maintained for a time determined by a capacitor, (C1, Fig. 3, not shown) in a control box 65, which begins charging when the valve 52 is energized. At the end of the set time the valve 52 closes and the reservoir 28 bleeds through pipes 27 and 25 to the chamber 23 and thence through a choke 93 and the chamber 16 to the outlet 22, the triple valve reducing the pressure in the pipe 34. At a set lower pressure a second choke valve 94 opens to dump the pressure in the chamber 23. Should the train driver apply the brakes during an overcharge the valve 26 is closed and a switch 77 subject to brake pipe pressure and say 5 bar above and below its diaphragm closes until the brakes are released. When the brake pipe pressure reaches 5 bar the switch 77 opens and the overcharge is reapplied. An alternative application of the system to an existing brake system is also described. Reference has been directed by the Comptroller to Specification 1,291,230.

Title: Improvements in and relating to fibre strengthened materials
Inventor: CHARLES JAMES ANTHONY
IPC: C21D8/00
Filed: 1963-04-08
Abstract: An alloy having a banded micro-structure of one or more phases in a ductile phase, at least one of the former phases being capable of plastic deformation and of being converted by heat treatment to a hard strong form, is worked to deform that phase and is then heat treated to harden that phase without destroying the ductility of the matrix phase.  The process may be applied to a steel having for example 0.2% carbon and 0.45% manganese, and a banded structure of ferrite and pearlite, which is worked and then heated to a temperature such as 750 DEG C. for a few seconds to convert only the pearlite to martensite, and then quenched before general diffusion of carbon occurs.  Alloys having the desired banded structure may be produced by bonding together by heavy deformation a mass of alloy parts together with other alloying materials which interact therewith to produce phases harder or stronger than the initial alloy.  In a further embodiment sheets, bars or wires of alloy steel are coated with ferrite stabilizing elements such as chromium, tungsten, molybdenum, silicon, vanadium, phosphorus, titanium, tin, niobium or aluminium and bonded by working to produce a body having bands of ferrite interspersed possibly with bainite or martensite.  Examples of such composites are a steel containing 0.45% carbon and 2% manganese bonded with iron containing 12% aluminium in a 1:1 ratio, and steel containing 0.028% carbon and 1.55% aluminium bonded with steel of 0.84% carbon and 0.82% manganese in a 1:1 ratio.
