Title: Improvements in track construction for endless track vehicles
IPC: F16G13/06
Filed: 1945-11-21
Abstract: 606,143. Endless tracks for vehicles. FOOD MACHINERY CORPORATION. Nov. 21, 1945, No. 31304. Convention date, March 4, 1943. [Class 79 (i)] An endless track for vehicles comprises a series of inside links alternating with a series of outside links the ends of which overlap the ends of the inside links and are pivotally jointed thereto, elastic rings interposed between the opposing surfaces of the links and tightly compressed therebetween, the rings forming seals for preventing loss of lubricant and ingress of dirt to the joints, the elasticity of the rings and the degree of compression to which they are subjected being correlated with respect to the chain pitch and sprocket diameter to allow internal torsional displacement of the rings when the chain passes over the sprockets, so preventing slipping of the rings with respect to the links. As shown in Fig. 1a, each track comprises a pair of chains 30 secured together by grousers 31. Each chain comprises an assembly of inside and outside links. The inside link 40 consisting of a channel-shaped member with a web 44 and walls 43, the walls at each end having bores 45, 46 into which is pressed a bearing sleeve 47. The outside link is similarly a channel-shaped member having a web 76 and walls 75, the walls at each end having bores 78, 79. The links are pivotally joined by a pin 60 secured by rivetting. To prevent loss of lubricant and ingress of dirt a rubber sealing ring is 85 interposed between the walls of the inner and outer links. The ring is protected by a metal sheath 88. The ring is made of such a size as to be compressed that when relative movement takes place between the links, the friction force between the faces of the ring and adjacent faces of the links is such as to prevent slipping of the adjacent faces and deflection can only take place through torsional deflection of the rubber for normal deflection. For abnormal deflection as when the track is rolled up the rubber ring would slip with respect to the link faces. In order to avert friction between the inner face 90 of the ring and the surface 89 of the bearing sleeve 47 the said surface is made concave and the ring is provided with a bead 95 on its outer face for the same purpose, e.g. as described in Specification 606,144.

Title: Improvements relating to cathode ray tubes
IPC: H01J9/22
Filed: 1956-10-19
Abstract: An organic film is deposited on a phosphor screen of a cathode-ray tube as a temporary step in the process of providing the screen with a metallic coating (see Group XL (a)) by floating it on the surface of a supporting solution which contains at least one water-soluble salt, e.g. potassium silicate, calcium nitrate, aluminium nitrate or trisodium phosphate, to improve the adhesion of the film and subsequently pouring off the supporting solution so that the film adheres to the surface.  Potassium silicate with an average mol. ratio of K2O to SiO2 of 1:3.45 is preferred.  The organic film may comprise nitrocellulose and a plasticizer in amyl acetate.  The phosphor screen is first applied in the form of silicates while the solution for supporting the organic film contains potassium silicate. Specification 693,672, [Group XL (a)], is referred to.
Patent GB-519496-A (GB)
Title: Improvements in and relating to pick-up control mechanism for automatic gramophones
IPC: G11B3/52
Filed: 1938-11-04
Abstract: 519,496. Gramophone pick-up arm control mechanism. GARRARD ENGINEERING & MANUFACTURING CO., Ltd., and OFFEN, F. J. Nov. 4, 1938, No. 32040. [Class 40 (ii)] Relates to pick-up control mechanism for use in automatic gramophones having a feeler arm which is moved into and out of contact with the edge of a positioned record to detect its diameter. According to the invention, the return movement of the feeler arm is utilized to cause a pressure yieldably to be, applied to the pick-up arm to push the pick-up needle into the starting groove of the record after it has been deposited on the edge of the record. As shown in Fig. 1, the pick-up arm 1 is pivoted on an horizontal pivot 3 on an arm 4 on a vertical rotatable spindle 5 through which a rod 6 passes for lifting and lowering the pick-up. The diameter of the record is detected by a " feeler" arm 21 having a roller 22 at its free end which is brought against the edge of the record under the influence of a spring 28, Fig. 2, when a drum cam 26 co-operating with a lever 23 on the spindle 24 of the feeler arm 21 allows the inward movement of this lever. After this, a cam 19a allows a bell-crank 14 to be moved by a spring 20 to cause a lug 13 thereon to bear on a pin 16 on a lever 17 fast with the sleeve 5 and thereby swing the pick-up arm inward. This inward movement is limited by the abutment of a stop 36 on the lever 17 against a pin 30 or 31 on a lever 29 fast on the spindle of the feeler arm 21 according to the diameter of the record. The needle 2 is now just over the edge of the record and is lowered thereon by the co-operation of cam 12a with lever 7 pivoted at 8 and having a forked end 9 bearing on a collar 10 on the rod 6. During this lowering operation, horizontal displacement of the pick-up arm is prevented by a frictional grip due to the wedging of the pin 30 or 31 between the stop 36 and a rectangular stud 37 on the lever 17. After the needle has been lowered, drum cam 26 operates to withdraw the feeler arm 21 from the edge of the record, whereupon the pin 30 or 31 acts on lug 35 on a small lever 33 pivoted at 32 on the lever 17 and influenced by a spring 34 anchored to the lever 17. This spring thus transmits movement to the lever 17 causing the needle to be moved inward to engage the starting groove of the record. When the record is played, the needle follows the grooves and the lever 17 moves freely away from the reach of levers 14 and 29. This pick-up control mechanism may be used with the record-changing mechanism described in Specification 486,999 and with the record-delivery mechanism described in Specification 511,840.

Title: Improvements in brakes for textile spinning and like spindles
Inventor: BARRETT WALTER
IPC: D01H7/22
Filed: 1964-08-06
Abstract: Means for braking a spinning &c. spindle, comprises a stationary assembly, 11 Fig. 2 (not shown), for supporting the spindle, on which assembly an annulus 22 is slidably and rotatably mounted; the annulus has cam-means 25 which, when the annulus is rotated, co-operate with cam-means 26 in the assembly to raise the annulus to engage a flange 19 of the wharve and lift it into engagement with a braking surface 21 on the assembly.  The assembly 11 comprises a bolster with a nut 15 which draws a flange 12 into engagement with the base of a housing 20 resting on the rail 14.  The braking surface 21 is pivoted on an adjustable cap 21 which serves to prevent the whorl and spindle from being displaced upwardly.  The cam-means 26 are on a plate 27 secured to the base of the housing by springs 28.  To apply the brake, a handle 23 is rotated in the direction in which the spindle rotates so that the driving-torque transmitted through flange 19 assists the braking-action; this action is also assisted by the springs 28 acting through plate 27.

An assembly 23 for mounting a wheel balancer 31, 32 on a wheel 10 comprises a centrally flanged body 24 carrying a plurality of symmetrically arranged radially adjustable centring means 55, each having screw-threaded actuating means 43, 44 connected by gear means 48, 50, adjacent the central flange 25, with a common control means 51, 52 for simultaneous centring operation into engagement with the wheel. As shown, the centring means 55 comprise rim-flange engaging fingers each removably pinned to a slide member 40 which is radially adjustable in a bracket 36 riveted to the body 24. Each slide member 40 carries a fixed nut 42 having screw-thread engagement with one end of a shaft 46, the other end of which is keyed to a pinion 47 and secured against axial displacement to the body flange 25. Simultaneous rotation of the pinions 47 to effect centring displacement of the finger-carrying slides 40 is effected by a ring gear 50 which is secured to a manually-rotatable collar 51 to embrace, and bear about the flange 25. The assembly 23 is secured to the wheel 10 by two connectors 60 each shaped as shown in Fig. 7 to provide an off-set apertured foot 61 to fit over a wheel-fixing stud, and having aligned apertures 64, 67 and 74 on its weight distribution axis X-X to receive assembly-body holding screws 65 which engage a screw-threaded sleeve 68 fixed in the aperture 67. The off-set feet of the connectors provide for diametricallyopposed spacing of the body-holding screw apertures whether or not there is a pair of diametrically - opposed wheel fixing studs. Correct centring and spacing of the connectors 60 on the wheel 10 is achieved by a ring tool which is manually centred over the axle cap 13 and has locating spigots to fit in the connector apertures 74. With the connectors centred and clamped on the wheel by the wheel securing nuts 22, the body 24 is screwed thereto and finally centred by operation of the fingers 55. The balancer 31 is then mounted on the body 23 as by clips engaging equispaced posts 33 on the body periphery.

Title: Improvements relating to the reduction of sparking at contacts in making and breaking electric circuits
IPC: H01H9/54
Filed: 1932-11-14
Abstract: 407,780. Sparking - preventing in switches; light-current relays. SIEMENS BROS. & CO., Ltd., Tothill Street, London, and EDWARDS, H. J., 5, Summerhill Road, Dartford, Kent. Nov. 14, 1932, No. 32186. [Class 38 (v).] In order to minimize sparking at the contacts when light-current relays of the type used in communication are used to control currents at voltages of the order of power systems, as in traffic signalling systems, the relay load contacts are associated with other contacts adapted temporarily to connect a condenser across the relay load contacts, the control of the other contacts being so effected that a delay is introduced between the opening of the load contacts and the condenser contacts. In Figs. 1, 2, the relay contacts a<1> control the load circuit pl and are shunted by a condenser QA and contacts b1 forming a circuit having a minimum of resistance. When a1 are to be closed, the armature A is arranged first to close b1 to complete the shunt circuit through QA, and when a1 open, they are protected by QA which is subsequently disconnected by the opening of b1. Alternatively, b1 may be controlled by a relay which may be either rendered sluggish in action, Fig. 3 (not shown) or controlled by a contact which is opened by the relay controlling a1, Fig. 4 (not shown). The contacts b1 may alternatively be themselves shunted by a similar protective condenser and contacts, Fig. 5 (not shown). In Fig. 6, the contacts a1 close first so that QA is not charged when b1 close. The charge acquired between the opening of a1 and the subsequent opening of b1 is dissipated in a resistance YA, thus protecting a1 against sparking when they are closed. In another form, Fig. 7 (not shown), the resistance is connected in circuit only after b1 have opened. The invention is also shown in its application to a system wherein several relays have a common condenser and set of spark-taking contacts controlled by a relay, Fig. 8 (not shown).

Abstract: 939,109. Programme controls for sterilizers. AMERICAN STERILIZER CO. Sept. 20, 1960 [Sept. 21, 1959], No. 32317/60. Class 81(1). An arrangement for the automatic control of a steam-pressure sterilizer device provided with an autoclave, which comprises a plurality of programme control members each arranged to control the phasing of an invariable sterilization programme, a selector device operable to bring any one of the control members into operative association with means for causing such operative control member to actuate operating elements for operating the sterilizer device, and a sensing device responsive to an operating condition of the sterilizer device and arranged to restart any sterilizer programme in which such operating condition fails to achieve a predetermined standard. If there is a fault in the carrying out of a programme, e.g. too low a vacuum or too low a temperature, the programme is discontinued and is automatically repeated after the programme store has been returned to its initial position. As shown, the steam pressure sterilizing device comprises an autoclave 1 to which steam at a predetermined pressure is led through a double cover from a steam source 29, through an interposed cut-off valve 2 and a pressure control 3, and into the autoclave through a valve 4, a condensation remover 5 serving for the drainage of the steam. Six cam-shafts 22, 40, 43, 44, 45, 46 are arranged on a selector disc 27 with a click-stop device 28. Each cam-shaft comprises, corresponding to their particular arrangement and construction, the individual cams of a predetermined programme. They can be brought in accordance with their programme into the functional position by the main shaft 19 of the driving device comprising an arm 20 pulled by solenoid 23 to bring a pinion 21 rotated by gear-wheel mounted on shaft 19 and driven by motor 36 into engagement with a corresponding gear-wheel on the particular cam-shaft selected. On rotation the cams actuate microswitches 26 which control solenoid valves 13, 14 and 15 to which vacuum is applied on energization of a vacuum pump 11, movement of a cam-shaft 22 operates microswitch and applies vacuum to valve 7 to open it and the autoclave is evacuated and after a certain time is closed and steam valve 4 opened to allow steam into the autoclave and after a further period the live steam valve 4 is closed by operation of a microswitch and the vacuum valve 7 again opened for carrying out the drying process. The end of the programme is determined by the cam operating the switch for stopping the vacuum pump when no driving means is available for actuation of the valves. The operation may be performed manually and instead of the vacuum pump a water jet pump can be used.

Title: Process for the manufacture of candles, tapers and the like and to an apparatus for carrying out such process
IPC: C11C5/02
Filed: 1923-12-27
Abstract: 231,235. Burian, E. Dec. 27, 1923. Candles and tapers are made by repeatedly passing the wick through molten wax or the like and a die until the desired thickness is obtained, the die being expanded or replaced by a larger one, without loosening the wick, each time the full length of the wick has passed through the bath. The coated wick is cut into candle &c. lengths and headed &c. in known manner. Candles with layers of different quality may be obtained by changing the contents of the wax &c. bath. In the apparatus shown, an endless band 4 of wick passes through a bath 5 of wax, a 2-part die 12 in a clamp or tongs 11, and over drums 1, 2, 3. The clamp 11 is carried by a bolt 14 removably secured by screws 16 in a socket 15 on the edge of the bath. Each time the wick has passed through the bath the clamp is replaced by one containing a larger die. The drums 2, 3 are slightly inclined to each other to - ensure close winding, a grooved roller 9 is adjustably pressed against the wick to keep it in the centre of the wax coating and to ensure the windings on the drums 2, 3 are kept parallel, and the drum 2 is mounted on a frame 6 slidably arranged on a frames 7 so that the distance between the drums 2, 3 can be adjusted to allow for the lengthening and thickening of the wick as it is impregnated. The die can be adjusted automatically by connecting the adjusting mechanism to one of the drums or to the driving mechanism, and the contents of the bath may be replaced automatically, e.g. after the wick has passed through the bath one or more times, by connecting to the driving mechanism the valves governing the supply and removal of wax. In a modified apparatus the wick is drawn backwards and forwards through the bath, and a replaceable and adjustable die is put at each side of the bath.
