Patent GB-253141-A (GB)
Title: Improved device for time-setting and winding of a time indicator, such as a watch
IPC: G04B3/04
Filed: 1926-06-04
Abstract: 253,141. Soc. Anon. le Coultre et Cie. June 6, 1925, [Convention date]. Keyless mechanism which comprises a winding stem 10 arranged radially and in a parallel plane to the movement plate 11, the stern carrying a single pinion 17 and being slidable axially so that this pinion engages with a crown-wheel 18 for winding or with an intermediate wheel 19 for time setting, is provided with means for positively locking the stem in either of its set positions. Annular grooves 15, 16 in the stem coact with a spring 13 fixed to a plate 12, which plate 12 is attached to the movement plate 11 and holds the stem 10 in position. Engaging the lower face of the groove 16 and the undersurface of the pinion 17 is the claw-shaped end 23, 22 of a lever 20 pivoted at 21. When the stem is raised to engage the wheels 17, 19 for time setting the other end 26 of the lever 20 is thus also raised and prevents movement of a pin 28 on a pawl 27 of the spring winding mechanism. This prevents winding taking place during time setting. Conversely, during winding the pin 28 moves from the A to the B position and prevents movement of the lever 20 maintaining the wheels 17, 18 in engagement.

Filed: 1944-07-28
Abstract: 596,372. Asymmetrically-conducting resistances. STANDARD TELEPHONES & CABLES, Ltd. July 28, 1944, No. 14446. Convention date, Oct. 26, 1943. [Class 37] In the manufacture of rectifying buttons such as are connected in series to form a multiunit rectifier, a metal sheet 12 formed with holes as at 26 and partially punched out buttons 14 is supported on a fixture and covered by a mask apertured to receive the buttons 14. A layer of selenium powder is sprinkled over the mask and the mask removed leaving a layer 18 of selenium on each button, which is then suitably formed by pressure and heat. The plate 12 is then removed to a similar support 191 (Fig. 7) and an insulating mask 20, having apertures coinciding with but smaller than the buttons 14, is superimposed, followed by a mask 29 with larger apertures through which the counter-electrode alloy layers 30 are applied. The rectifier buttons are then electroformed as from a common electrical source having connection with each counter-electrode and the base plate 12. The buttons are then knocked out and extraneous portions of the mask 20 removed. This is facilitated by partially pre-punching the mask, which is, for example, a thin sheet of resinous material or insulating paper. Fuming with selenium dioxide may be included in the usual manner. The use of the mask 29 and the mask used for applying the selenium layer is not essential. Specifications 526,482 and 564,973 are referred to.

Patent GB-277118-A (GB)
Title: Improvements relating to vacuum braking apparatus for railway trains
IPC: B60T13/46
Filed: 1926-06-11
Abstract: 277,118. Le Clair, L. J., Brackenbury, A. G., and Westinghouse Brake & Saxby Signal Co., Ltd. June 11, 1926. Fluid - pressure.- A vacuum braking apparatus for railway trains comprises a brake application device provided with a valve 4 for automatically establishing communication between the train pipe and the atmosphere in which the flow of air to the train pipe through the automatic valve 4 is arranged to be independently controlled by a valve 15, so as to permit of graduation independently of the extent of opening of the automatic valve. The opening movement of the valve, in an emergency application, is effected automatically by the pressure obtaining within a vacuum chamber 2 relative to that obtaining in the train pipe 44. The stem of the valve 4 is perforated to receive a cam 10 on a spindle 11 and is extended and attached to a diaphragm 7 separating a vacuum chamber 2 from an atmospheric air chamber 5. The supply of air to the chamber 5 is regulated by a cylindrical valve element 14 provided with a valve 15 which co-operates with a valve seat 16 on the body portion 1. The valve 15 and valve seat 16 are provided with ports which register in the " off " position of the valve 4. When the handle 19 attached to the valve element if is moved from the " off " to the " on " position the valve 4 is raised by the cam 10 and the ports in the valve 15 and seat 16 at first close and then admit air into the chamber 5 by means of a narrow circular port in the valve overlapping one of the ports in the seat 16. This part of the movement corresponds to a service application of the brakes. Further movement of the handle 19 causes large ports in the valve 15 and seat 16 to register so that the chamber 5 is in free communication with the atmosphere, this position corresponding to an emergency application of the brakes. The valve 4 is opened automatically when air enters the pipe 44 during an application of the driver's valve. The air enters the vacuum chamber 2 through a small port 8 in the valve 4 so that the pressure of the atmosphere on the diaphragm 7 opens the valve. In modifications the air can be admitted to the train pipe through restricted orifices covered by a valve mounted on the valve 4, which former valve is raised in the initial movement of a lever, the valve 4 being raised after the orifices have been uncovered. The handle 9 and valve element 14 may be looselv mounted on the spindle 11 and a catch handle provided so that the valve 4 is only opened when the catch is properly gripped by the operator.

Title: Process for tempering vitreous and vitro-crystalline bodies
Inventor: DUTHOIT JEAN
IPC: C03C21/00
Filed: 1968-03-27
Abstract: 1,220,292. Chemical tempering. GLAVERBEL. 27 March, 1968 [28 April, 1967], No. 14778/68. Heading C1M. A body of glass or vitrocrystalline material is strengthened by an ion-exchange treatment, preferably of alkali metal ions, wherein metal ions in exterior layers of the vitreous body are substituted by other metal ions which diffuse into the body from a contacting medium, the nature of the ions and the temperature conditions being such that compressive stresses are set up in the exterior layers of the body either during the ion-exchange or when the body cools, the treatment being characterized by causing the temperature of the body to decrease substantially during the ion-exchange period, preferably by at least 40 C. If the substituting ions confer a lower coefficient of thermal expansion on the external glass layers, such as in the substitution of sodium ions in the glass by lithium ions, the initial temperature of the ionexchange is at least 1À05 Tg, where Tg is the temperature at which the glass viscosity is 10<SP>13.3</SP> poises. If the metal ions in the glass, e.g. Na<SP>+</SP> are replaced by larger metal ions, e.g. K<SP>+</SP>, the initial temperature of the ion-exchange is at least 0À6 Tg. Soda-lime glass or a vitrocrystalline material of the following composition in per cent by weight may be chemically tempered by this treatment: SiO 2 : 42À3; Al 2 O 3 : 31À2; Na 2 O: 10À4; K 2 O: 6À2; CaO: 1À8; TiO 2 : 7À4; As 2 O 3 : 0À7. The treatment may be carried out by conveying sheets of the vitreous material on an endless conveyer carrying racks through a tank of the ion-exchange medium in which the temperature decreases along the conveying path. A drawn glass ribbon may be treated by passing it over a bending roller at the top of a vertical drawing chamber and then along a horizontal lehr in which a tempering bath is provided through which the ribbon of glass is guided and progressively cooled. In another embodiment the ion-exchange medium forms a coating on the glass body. For example, a sheet of sodalime glass preheated to 490 C. can be immersed in and withdrawn from a bath of KNO 3  at 490 C. and then cooled slowly to 350 C.

Title: Improvements in magneto electric machines
IPC: H02K21/32
Filed: 1919-06-11
Abstract: 141,554. Olivetti, C. June 11, 1919. Magneto-electric machines. - Magnetos for igniting in internal-combustion engines and for other purposes are constructed to give six maxima of tension for each revolution of the armature: the maxima may occur at equal or unequal intervals from one another. Figs. 1 and 2 illustrate a construction in which maxima occur at intervals of 30, 60, 90, 30, 60, 90 degrees, as shown by the depressions 34, Fig. 14, of the interrupter cam 32. The field-magnet comprises one or more permanent magnets 12 fitted with pole-pieces 3, 3<1>, and between the rotating armature core 1 and the polepieces there are arranged four segments 4, 4<1>. 5, 5<1> of magnetic material. These segments are firmly held by two non-magnetic plates 6, 7 which may be adjusted for timing purposes through a limited angle around the armature shaft; two of the segments 4, 4<1> rest against the pole-pieces 3, 3' while the other two segments are positioned in the interpolar gaps. The armature comprises a soft iron core 1, carrying primary and secondary windings 16, 17, and two arc-shaped soft-iron segments 2, 2<1>, spaced apart from the ends of the core 1; the several parts ure secured together by means of end pieces 8, 9 mounted in bearings 10, 11. The intervals separating the maxima may be altered by suitably proportioning the lengths of the segments and of the ends of the armature core. The low-tension winding 16 is connected to an interrupter having an oscillating lever 41 and carried on the plate 7. Six sparks per revolution may be obtained by using an internal cam 32 with six projections or depression 34, as shown in Fig. 14, or four sparks having a relative displacement of 90 degrees by using cams of the character shown in Figs. 17 and 19. Magnetos of the type described may be arranged to give two sparks per revolution by turning the stationary segments into the position shown in Fig. 8. The segments 4, 4' may be omitted, Fig. 7. Modifications in which sparking occurs at unequal angles may be used for the ignition in V-engines.

Title: Improvements in fire ladders and the like
IPC: E06C5/34
Filed: 1927-06-02
Abstract: 279,348. Merryweather & Sons, Ltd., Osborne, J. H., and Burford, A. W. June 2, 1927. Portable wheeled ladder escapes.-The invention relates to ladder escapes more particularly of the kind described in Specification 167,397, and consists in the provision of improved control means whereby the extension of the ladder is limited according to its degree of elevation and lowering of the ladder can only follow a definite collapsing of the same. Clutches a, b which control the elevating and lowering of the ladder and clutches c, d which control its extension and collapse are respectively operated by arms 1, 2 through links 5, 6, bell-cranks 3, 4, and handlevers (not shown). Within a casing 10 a spindle 7 is arranged for rotation by a keyed worm-wheel 13 in mesh with a worm 15 driven from the ladder-elevating gear. The spindle rotates within an externally-threaded sleeve 9 which works through a nut 17 formed with a worm wheel 18 in mesh with a worm 19 driven from the ladder extending gear. The spindle 7 carries a head 21 having a cam face 22 designed to co-operate with rolls 23 on the bell-cranks 3, 4. In use, if an attempt is made to extend the ladder without elevating it, the sleeve 9 and spindle 7 will be moved axially until the head 22 moves the lever 4 to declutching position. If, however, the ladder is at the same time elevated, the worm 15 will rotate the spindle 7 until the low part of the cam 22 is opposite to the bell-crank 4, allowing extension to continue. Similarly, the bellcrank 3 can only be moved to lower the ladder if a corresponding collapsing of the ladder has already caused the spindle 7 to be withdrawn to the right.

Title: Synchronous motor controls
IPC: F04D9/00
Filed: 1960-04-28
Abstract: 904,930. Control of A.C. motors. WESTING- HOUSE ELECTRIC CORPORATION. April 28, 1960 [May 7, 1959], No. 14875/60. Class 38 (3). A control system for a synchronous motor 2 having a field winding 4 adapted to be connected to D.C. excitation leads 8 comprises a speed sensing circuit 26 operably connected to the field winding and providing a signal in accordance with the frequency of the motor slip, a polarity sensing circuit 28 connected to the field winding and providing a second signal during the intermediate region of the first half of the half cycle of induced field current of polarity opposite to the excitation source applied to the field winding, a pull-in sensing circuit 32 connected to the field winding and providing a third signal in the absence of a second signal, after a predetermined time delay, from said polarity sensing circuit, and an amplifier and power switching circuit 30 responsive to the simultaneous occurrence of either the first and second signal or the first and third signal for connecting the field winding 4 to the excitation source by way of a contactor 14 with an operating coil 16. As shown, the circuits 26, 28 and 32 comprise NOR elements, i.e. circuit apparatus adapted to provide an output in the absence of an input to the apparatus, and the circuit 30 includes NOR elements 300, 302 connected to form a flip-flop or MEMORY element 304. While the motor 2 is accelerating an input to the NOR element 300 appears periodically from the polarity sensing circuit 28, but an input signal from the speed sensing circuit 26 to the NOR element 302 prevents the MEMORY element 304 from switching " on " with a resultant output therefrom. At the desired synchronization speed both inputs to the NOR element 302 are zero so that the next signal from the polarity sensing circuit 28 to the NOR element 300 causes the MEMORY element 304 to switch to an input signal which, over an amplifying transistor 308 and a power transistor 312, energizes the operating coil 16 of the field contactor 14, whereby D.C. excitation is applied to the field winding 4. In some circumstances, e.g. when the motor 2 is started without load, the motor may synchronize prior to the application of the field excitation and in this case the polarity sensing circuit 28 which then has no output, is by-passed by the pull-in sensing circuit 32 which supplies a signal to the circuit 30 if the induced field current is zero, which signal replaces the signal from the circuit 28 in initiating application of the excitation to the field winding 4.
