Patent GB-332189-A (GB)
Abstract: 332,189. Hamilton, R. M. Feb. 15, 1929. Totalizators.-In an oddscalculating apparatus for a totalizator, mechanism is provided for automatically affecting the horse and pool settings by the act of stamping a ticket with the prevailing odds. As shown in Fig. 1 applied to the calculating apparatus pertaining to one horse, the issue in a booth, 11 of a ticket on that horse advances a shaft 15 through the medium of a collector unit 14 and through a hunter gear 23 actuates one member 24 of a differential gear 25 driving a logarithmic drum 28 controlling a secondary drum 31. An impulse is simultaneously transmitted by a wire 16 to a pool collector 17 operating through another differential gear 36 a similar primary drum 38 and secondary drum 40. The difference of rotation of the secondary drums operates through a gear 43 the odds-indicating shaft 45, an arm 51 on which controls through lines 53 the setting of the odds-printing type in the stamping-machines 50. The shaft 45 also controls an odds-indicator 68 such as that described in Specification 326,152 and also the position of a multiplying-selector 64. When a ticket is stamped, unity is deducted from the horse side of the odds-calculating apparatus by means of a line 54 and a collector unit 55 connected with the other driving-member 57 of the differential gear 25. When the collector assemblage has moved through a pre-determined amount equal say to 10 units a contact is made at 66 to send an impulse through a line 65 to the multiplying- selector 64 and thence in the form of a product to pool-deducting collectors 58 geared to the driver 63 of the pool differential gear 36. These latter collectors are geared together successively in a 1 : 2 ratio so that by selecting one! or more of the units for operation, the wheel 63 can be given a rotation, equivalent to any value from 1 to 1023. The multiplying-selector 64 may take the form of a drum provided with a number of contact bars of different lengths and so positioned as to energize the lines leading to the collector units in combinations corresponding in effect with the setting of the shaft 45 and therefore of the drum. A convenient practical grouping of the various members shown diagrammatically in the figure is illustrated in the Specification. Specifications 307,816, 324,658, 326,444 and 331,539 also are referred to.

Title: Improved apparatus for the production of artificial silk
IPC: B65H75/24
Filed: 1930-11-05
Abstract: In the manufacture of artificial silk the spun material is wound on an unsplit resilient or collapsable sleeve e, for example of rubber, mounted on a rigid bobbin a, a second sleeve b of rigid material and split so as to be capable of contraction being interposed between the first and the bobbin, so that the sleeves and the material may be readily withdrawn from the bobbin.  The second sleeve is contracted and removed, thus permitting the first to be collapsed and removed without damaging the material, but the material may remain on the <PICT:0368748/IV/1> <PICT:0368748/IV/2> first sleeve for further treatment, the sleeve being then preferably perforated.  The sleeve b is held on the bobbin by the engagement of keys d on the bobbin with the slit and is provided with a spring handle c.  The Provisional Specification describes also a tube adapted to be placed on a plain bobbin to receive the silk and provided with a projection or flange to serve as a grip to facilitate removal, the tube being of rubber, celluloid, or other thin resilient material.

Title: Improvements in or relating to electric remote control systems
IPC: G08C19/48
Filed: 1936-12-04
Abstract: 487,226. Electric signalling systems. VICKERS - ARMSTRONGS, Ltd., and WATSON, J. P. Dec. 4, 1936, No. 33349. [Class 40 (i)] In a remote control system, the field winding 1 of the transmitter is connected to the supply, the armature 2 being connected to the stator winding 9 of the receiver having an armature with one or more paths 14 of low magnetic reluctance. For asynchronous running, the rotor 13 is provided with conducting paths to allow induced currents to circulate in the manner of an induction motor rotor. In order to provide the necessary phase shift in the supply to the receiver, a condenser 23 may be inserted in one of the lines. In a modification, Fig. 5, the switch 27 has four positions, and the rotor consists of two parts, rotor 37 being of the type used in Fig. 2, while rctor 38 is of the squirrel cage type. As shown the receiver rotor will run as an induction motor, whereas upon the connection, segment 36 to stud 29, being completed, the rotors will move in synchronism. With the switch arm 27 on the stud 32, there will be a position of the rotor 2 where no current is supplied to stator 9 and upon its being turned from this position, the rotor 37, 38 will rotate asynchronously, its velocity being dependent on the deviation of the rotor 2 from its zero position, but independent of its sign. In order to provide rotation of rotor 13 in the opposite sense, the switch arm contacts with stud 34. Instead of a composite rotor, a rotor as used in Fig. 2 may be employed. In a further modification, separate stators 9 and rotors 37, 38 are used, the supply being fed to one or other of the stators and a second switch being used to perform the functions of switch 27. Where there is persistent lag between the rotors, the difference between the position of the transmitter and receiver may be arranged to operate a hunter switch to cause the receiver to be carried towards synchronism by induction motor effect.

Title: Improvements in or relating to overload couplings
IPC: F16D43/20
Filed: 1956-11-01
Abstract: 799,816. Overload release positive clutches. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 1, 1956 [Nov. 4, 1955], No. 33373/56. Class 80 (2). An overload release clutch for use in shaft positioning mechanism &c. comprises a driving bevel gear 3 and shaft 2, an intermediate sleeve 8 screwed into a thread 7 the driving shaft, and a driven shaft 4 connected to the intermediate sleeve by a torsion and compression spring 12, a radial pin 11 in the driven shaft engaging with circumferential lost motion an axial slot 10 in the intermediate sleeve 8. When the load on the driven shaft 4 becomes excessive, the intermediate sleeve 8 is screwed out of the driving shaft 2 until it is no longer in threaded engagement therewith, against the torsional and compressive bias of the spring 12. When the intermediate sleeve 8 has been completely disengaged from the thread 7 in the driving shaft 2, teeth 9 on its periphery engage a stop 13 on a surrounding stationary casing 1, so that it is prevented from rotating backwards. Axial movement of the intermediate sleeve 8 when it is being screwed out of the driving shaft 2 also actuates a switch 15 to switch off an electric motor (not shown) driving the bevel gear 3 and shaft 2. To reengage the clutch after removal of the overload, the electric motor is caused to rotate in the opposite direction and the intermediate sleeve 8 screwed back into position. The spring 12 may be connected to the shaft 4 by adjustable means so that variation in the compressive and torsional bias can be effected. So that the clutch can be operated in both directions of rotation, instead of only one direction as shown, two oppositely threaded intermediate sleeves 8 may be provided.

Abstract: 1,112,324. Selective printing. CREED & CO. Ltd. 26 July, 1966, No. 33495/66. Heading B6F. Electrostatic printers.-An electrical signal operated character-by-character printer comprises a cruciform member 14 having four photo-sensitive surfaces 6 which are in turn: charged electrostatically at 17, exposed to a light image at 6, applied with dust ink particles at 15, and which are transferred to a printing surface 18 at position 16. Character selection.-A binary input signal is fed into a comparitor 10 and when a code 27 on a rotating stencil 1 sensed at photosensor 8 and which is identical with the incoming code, the output of the comparitor operates a flash control unit 13. This causes an image to be formed on the surface 6 by the light from the character which is in position 4 which corresponds to the code at the sensor 8. The sensor 8 may operate photo-electrically, magnetically or electrostatically. Impression arrangements.-Transfer of the ink particles is effected by pressing the platen 19 towards the ink surface 6. Housing.-The units 17, 5, 15 are in lightproof housing 20. While the store member 14 is exposed to light at the printing position, the dust particles cover the electrostatic image which is consequently not seriously damaged.

Title: Device for Determining the Temperature of Electrical Apparatus
Inventor: WALKER EDWARD PIPER
IPC: H01H37/00
Filed: 1966-07-26
Abstract: 1,161,985. Measuring temperature electrically. ENGLISH ELECTRIC CO. Ltd. July 25, 1967 [July 26, 1966], No.33644/66. Heading G1N. [Also in Division H2] In measuring the temperature of an electrical apparatus, e.g. a transformer, a temperature sensing element 1 Fig.1 is mounted in the oil in the upper part of the transformer and is incorporated in a heat sink arrangement, including heater windings 7, 8 supplied with a proportion of the transformer load current, which heat sink is designed to produce a "thermal image" of the temp. /time characteristic of the transformer. The arrangement compensates for errors due to time lag in the conduction of heat from the transformer windings to the sensing element. Temperature detector - Fig. 1 This comprises a positive temp. coefficient of resistance sensing element 1 encapsulated in silicone rubber 2 housing in fibreglass tube 3 surrounded by epoxy resin 4 in a paper housing 5. Heater windings 7, 8 are connected in series as shown in Fig.3. The temp. /time characteristics of the element due to each heater and of the transformer, are illustrated Fig. 2 (not shown). The effect of the two heaters 7, 8 is additive to produce a temp. /time characteristic which accurately matches that of the transformer windings. Measuring and protection - Fig. 3 The sensing element 1 is connected in one arm of a bridge fed with a stabilized D.C. supply. A meter 18 is calibrated to indicate temperature. The heaters are supplied via a current transformer 14. The voltage across element 1 is applied to transistor amplifiers 21-24 in circuit with potentiometers 28-31 calibrated in temperature units, for adjusting the bias level which must be exceeded before an associated relay 25, 26 or 27 is actuated to initiate a function. Thus as the temperature increases relay 25 operates first to switch on a cooler. Further increase in temperature to a second predetermined level causes relay 26 to actuate an alarm, and at a greater temperature level the relay 27 is caused to actuate a trip circuit to protect the transformer. Measuring length of time at each temp. level. The voltage across the sensing element 1 is applied to a second set of transistor amplifiers Fig.4 (not shown) and relays which sequentially switch coulombmeters on to a constant current supply, only one meter being connected at a time. As each predetermined temperature value is attained a coulombmeter is connected and accordingly their readings given a measure of the total length of time at which the transformer has been at various temperature bands, over a number of years.

Abstract: 993,421. Hinges. GRETSCH-UNITAS G.m.b.H. Sept. 21, 1961, No. 33831/61. Heading E2F. A hinge for a horizontally pivoted window comprises a first attachment plate 4 (Figs. 1, 2, 4) adapted to be mounted on the stationary frame 1, a movable plate 7 pivoted to the plate 4 at 8, and a second attachment plate 6 adapted to be mounted on the movable frame 2 and having a pivot 16 adapted to be received in a bearing 14 on the plate 7. When the window begins to open the plates 6 and 7 rotate together about the pivot 8, rotation about the pivot 16 being prevented by the inter-engagement of members, such as a peg 17 and a groove 15, on the attachment plates. The members remain in engagement until the normal open position (Fig. 4) is reached, when the plate 7 abuts a stop 12 on the attachment plate 4 and rotation about the pivot 8 is arrested. The window can then be opened to the 180 degrees position by rotation about the pivot 16. A coiled spring 10 is located on the pivot 8 to urge the plate 7 against the plate 4 and thereby provide frictional resistance to the normal opening movement. The pivot 16 is retained in the bearing 14 by a screw 18, and various means for introducing friction at this pivot are described. In particular, the screw may carry a sleeve 21, Fig. 7, having a cut-away portion to enable it to engage the pivot, or the screw itself may be shaped to engage the pivot. Alternatively, the U-shaped bearing 14 may be formed in two sections pivoted together at the base and drawn towards one another by the screw. In a modification, Figs. 11, 12, rotation about the pivot 16 is prevented by the engagement of the peg 17 behind a rib 25 on the plate 4, a recess 26 being provided in the plate 7 to receive the peg. The stop 12 is replaced by a stop 24 projecting from the plate 4, and a member 27 located on the pivot 8 between the nut 9 and spring 10 is anchored to the stop at 28 and increases the friction at pivot 8.
