Title: Improvements in or relating to the construction of locomotive axle boxes and keeps
IPC: B61F15/04
Filed: 1932-01-26
Abstract: 386,449. Vehicle axle-bearings ; lubricating. ROGERS, J. D., 12, Wetherby Mansions, Earls Court Square, London. Jan. 26, 1932, Nos. 2383 and 15435. [Classes 12 (i) and 12 (iii).] In a locomotive axle-box of the kind in which the axle-box consists of an inverted U-shaped frame slidable between horn blocks the bearing being constituted by or accommodated in the arch of the frame, the vehicle springs are slung from the keep and the latter is connected directly with the axle-box. As shown in Fig. 1, a spring hanger s has trunnions t mounted in bearings u in the keep a, and the keep a has a dovetail recess q on each side engaging a rib on the axle-box r. A grease-container x within the keep has a perforated plate j and a spring- pressed follower-plate e. Two chains w on the plate e pass through holes in the keep and indicate the amount of grease in the axle-box and permit the plate e to be retracted when required. A cover-plate y can be removed to permit the introduction of grease into the container x from the side. This construction may be modified by suspending the hanger s by means of D or triangular shaped lugs directly from the floor of the keep. In a modification, the keep 10, Fig. 3, is integral with the hanger 11 and is connected with the axle-box 12 by two short cylindrical or taper pins 13 each of which has a central bore 14 for removal purposes. The keep may also be dovetailed to the axle-box. The dovetail keys on the axle-box 12, Fig. 5, which engage the keep, may be formed by welding a steel strip 17 into a shallow recess.

Title: Improvements in electric clocks and other time keeping apparatus
IPC: G04C15/00
Filed: 1934-01-24
Abstract: 432,272. Electric clocks. BURNAND, W. E., 14, Oakholme Road, Sheffield. Jan. 24, 1934, No. 2407. [Class 139] In a synchronous motor clock, wherein an auxiliary escapement controlled mechanism, wound by the motor, takes over the drive during current stoppages, time indicating hands driven respectively by the primary and auxiliary driving mechanisms are arranged to indicate the time of stoppage of the supply by the angular displacement between them. As shown in Fig. 1, a gear wheel A, driven by the synchronous motor, is rigid with wheels B, H, and drives a hand F<1> frictionally to facilitate hand setting. The wheel B through a gear wheel C winds the spring D of the auxiliary movement, a friction clutch interposed between C and D preventing overwinding. The spring D drives under the control of the escapement (not shown), a wheel E which through wheel G rotates a hand F<2> . The escapement is adjusted slightly slow and the hand F<2>, Fig. 2, which therefore tends to lag, is carried around by the ratchet wheel H and pawl I in synchronism with the hand F<1> during running of the motor. When the supply fails, the hand F<2> is rotated by the wheel G, so that when the motor again takes over the drive and hand F<2> is locked to wheel H the angular displacement between the hands indicates the time of stoppage of the supply. The hand F<2> may, alternatively, be locked to the hand F<1> electromagnetically and released when the supply fails and the arrangements shown may be applied to both the hour and minute hands of the clock. In a modification, another hand F<3>, Fig. 4, is frictionally driven by the hand F<2> but when the supply fails it is locked against forward movement by an arm K rigid with the hand F<1>. When the supply again becomes available the displacement between the hands F<3> and F<2> indicates the stoppage period.

Patent GB-888350-A (GB)
Title: Improvements in and relating to plants for the stacking of sheet metal
IPC: B65G21/20
Filed: 1960-01-25
Abstract: 888,350. Endless conveyers. UNGERER, F. Jan. 25, 1960, No. 2597/60. Class 78 (1). [Also in Group XVI] In a plant for the stacking of sheet metal the sheets are held by suction on the underside of an endless depositing conveyer belt before being dropped on a stack and suction heads are provided on the upper side of the lower strand of the conveyer, those suction heads which are situated above the stacking place and act on the sheet metal through the belt, being controllable by rays in dependence on the position of a sheet to be dropped. As shown, an endless conveyer belt 3 is driven by an electric motor 4 and has series of holes 23 therein arranged in longitudinally extending bands 25. The holes 23 flare outwards towards the outside of the belt 3. At the upper side of the lower run of the conveyer are mounted suction heads 6-11. The heads 6 form a series extending transversely of the conveyer belt and during operation of the machine exert continuous suction. There are three heads 9, Fig. 2, disposed transversely across the belt 3, one above each of the bands 25. Located outside and between the heads 9 over the parts of the belt 3 which are free from holes are further suction heads 28, 29, which exert suction continuously. The suction heads 7, 8, 10, 11 are arranged similarly to the heads 9. Metal sheets 16 are fed successively by a conveyer 15 to the lower run of the belt 3 where they are picked up and held in contact with the belt 3 owing to the suction exerted by the several heads 6-11. When a sheet reaches the position 16<SP>1</SP> its leading or trailing edge is detected by means sensitive to visible or invisible rays, e.g. a photo-electric cell, which actuates valves in the supply lines of the heads 7-11 so as momentarily to disconnect them from a source of suction and connect them to a supply of compressed-air. The sheet 16 is thereby detached from the belt 3 and, owing to its forward momentum, describes a parabolic curve in falling on to a receiving table 18 having a resilient abutment 19 which arrests the leading edge of the sheet. The actuation of the valves may be so rapid as to allow a longitudinal spacing of the metal sheets on the belt 3 of as little as one inch and there may be a delay, of variable length, between the sensing of a sheet edge and the actuation of the valves. The suction heads 28, 29 prevent sagging of the belt 3 and prevent it from flapping when compressed-air is blown through the heads 7-11. Instead of having holes the belt 3 may consist of an airpermeable fabric, e.g. wire gauze, in which case the suction heads have lips of resilient material which engage the belt. In modifications, the metal sheets are held away from the belt 3 by projections on the outside of the belt so as to permit a more rapid separation of the sheets from the belt. The projections may be in the form of individual lumps or longitudinal strips and may coincide with the holes 23.

A coiled spring 18 is arranged loosely around the lower part of the handle on which the sleeve 16 slides. The handle is formed with a central bore 14 and radial openings 13 whereby water from the inside portion of the material may drain away when the mop is twisted about the loose coils 18.
Patent GB-933634-A (GB)
Title: Control system
IPC: G05D23/22
Filed: 1960-01-25
Abstract: 933,634. Automatic control. LEEDS & NORTHRUP CO. Jan. 25, 1960 [Jan. 30, 1959], No. 2716/60. Class 38 (4). An electric signal dependent in magnitude and sense on deviation of a variable from a desired value is caused to correct the variable automatically and, during such correction only, the charge on the condenser varies until it cancels the deviation signal. In Fig. 1, variations of the temperature of a compartment 10 are detected by a thermocouple 14 which energizes an indicator 17 operating a balancing potentiometer 18. Indicator 17 also controls the slider of a potentiometer 22 so that an output voltage E 2  is produced having a magnitude and polarity corresponding to the extent and sense of deviation of the temperature from a desired value set by angularly positioning the body of potentiometer 22. The voltage E 2  is applied through a thermionic valve amplifier 35 to operate a relay 44 or 45, according to the sense of deviation, so that a servomotor 13 runs in the appropriate direction to correct the temperature by adjusting a valve 12 controlling the supply of steam heating to the compartment. Auxiliary contacts C associated with relays 44 and 45 complete charging circuits for a condenser 40 which then supplies an increasing negative feedback voltage to the input of amplifier 35. Resistors 56 and 73 may differ so that the time constant and hence the period of operation of motor 13 differs according to whether temperature is being increased or decreased. The voltage E 2  and the feedback voltage are alternately switched to the input of amplifier 35 by a vibratory relay within the amplifier. Closure of a switch 38 introduces a condenser 37 so that a rate component E 3  is added to the temperature deviation voltage, while closure of a switch 67 connects a discharge resistor to condenser 40 to introduce an integral component of control. Change over of a switch 60 introduces a voltage from a potentiometer 84 adjusted in accordance with changes of the temperature of the steam to anticipiate consequential changes of compartment temperature. Change over of switches 50-52 disables automatic control and permits servomotor 13 to be controlled manually by means of a reversing switch 77. Continued automatic balancing of the input voltages to amplifier 35 under manual control ensures that the system may be changed to automatic control at any time without shock. Application to the control of boiler pressure or temperature with servomotor 13 controlling the fuel supply to a burner is referred to. In a modification additional relays may be energized by amplifier 35 to control additional servomotors. The auxiliary contacts of the additional relays then connect additional resistors in parallel with the charging resistors of condenser 40 so that the period of operation of the servomotors is reduced when more are operated. Modification of the charging resistance in dependence on another variable is also described.

IPC: C03B37/04
Filed: 1964-01-24
Abstract: <PICT:0997307/C1/1> <PICT:0997307/C1/2> In the production of glass fibres in which molten glass is projected in the form of fine streams through orifices arranged in rows on the peripheral band of a rotating hollow body and the streams are transformed into fibres by the action of gaseous currents, the peripheral band is maintained at a substantially constant temperature throughout the whole of its height and the diameter of the orifices is given a decreasing value from the upper part of the band to the lower part so as to obtain fibres of substantially the same diameter.  The hollow body 1 has a band 2 with orifices 3 decreasing in diameter, for example, at the top, two rows of 1.1 mm.; middle, 14 rows of 1.0 mm.; at the bottom, 4 rows of 0.9 mm.  The molten glass is spread evenly over the band 2 from a distributer 4 having orifices 5, the distributer 4 rotating with the body 1.  The streams 9 are attenuated by blast from an annular chamber 6 with slot 7 and the temperature of the band is maintained constant by a high frequency coil 8.  In addition, as shown, a cooled screen 11 adjacent the slot 7 may be provided to assist in equalizing the temperature of the band 2 and to increase the velocity of the gaseous current.  A further blowing ring 12 may direct, through orifice 13, a current of fluid to envelope the fibres produced.  As shown in Fig. 3, the streams 9 from the largest diameter orifices A extend further and from the smallest orifices C a less distance than those through orifices B through the gaseous blast so that there is less entanglement of fibres. An upstanding tip 14 prevents diversion of the alternating gas to the space above the body 1.  Specification 812,657 is referred to.

Abstract: 883,386. Thermal switches; fluid-actuation of switches. ECKERFELD, A. Jan. 31, 1958, No. 3309/58. Class 38 (5). [Also in Groups XI and XIII] In Fig. 1, cold water controlled by a valve 2 flows through a pipe 4 provided with a heating coil 3, the water then passing into a chamber 6 which includes a bimetal diaphragm 7 engaged by a pin 11 of a switch 13 controlling the heating coil circuit. An adjustable throttle screw 10 is provided in a pipe 8 through which the water flows after leaving the chamber 6. Upon opening the valve 2, the pressure of the water causes the diaphragm to flex from the position shown and the switch contacts are closed. The layer of the diaphragm adjacent the chamber has a higher coefficient of expansion than the layer remote from the chamber, and upon being heated to a predetermined temperature by the heated water, causes the diaphragm to return to its original position and the switch contacts to separate. An indicator lamp 30 is connected across part of the heating coil. In the construction shown in Fig. 2, the surface of a bimetal diaphragm 27 nearest a chamber 19 is covered with a heat-insulating elastic material 29 which also surrounds the edge of the diaphragm, a switch-operating pin 26 which engages the diaphragm being enclosed by a corrugated packing 25. A pipe 18 connects the cold water supply pipe with the chamber 19 and flow of water through the apparatus is controlled by a valve 16 and a throttle 20, the latter causing the pressure in a chamber 22 to be lower than that in the chamber 19. The diaphragm is thus flexed from the position shown and contacts 28 are closed. The heatinsulating material 29 prevents the diaphragm from coming into contact with the cold water in the chamber 19.
