Title: Improvements in or relating to lubricating systems for dual wheel structures for vehicles
IPC: B60B11/02
Filed: 1939-07-29
Abstract: 531,837. Brakes for vehicle twin-wheels. DIFFERENTIAL WHEEL CORPORATION. July 29, 1939, No. 22081. Convention date, July 29, 1938. [Class 103 (i)] In twin-wheels for road-vehicles, which are normally independently rotatable but are clutched together upon the application of a brake to one of them so that both wheels are braked, means are provided for conveying lubricant from the wheel bearings to the relatively movable parts concerned in effecting the clutching action. The device is the same as that described in Specification 529,912 and comprises an inner wheel 12 mounted by bearings 4, 5 on the axle 1 and an outer wheel 22 rotatably mounted upon the hub 11 of the wheel 12. A brake drum 51 is mounted with limited rotation relatively to the wheel 12 being secured by bolts 95, to a carrier 40 rotatable upon the hub part 39 of the wheel, the bolts and projections 94 on the carrier extending through slots in the wheel 12. An annular plate 96 is secured to the drum 51 and the carrier 41 by the bolts 95 and has a finger 103 projecting between the ends of a friction clutch split-ring 77 adapted to engage a drum 71 secured to the outer wheel 22. A projection 83 fixed to the wheel 12 also extends between the ends of the clutch ring 77. Interengaging lugs 87, 88 on the ring 77 and wheel 12 position the ring laterally. Upon application of brake shoes 55 by cam 57 to the drum 51 the wheel 12 tends to turn relatively to the drum causing relative displacement of the projections 83, 103 thus expanding the clutch ring 77 against the drum 71 so that the wheel 22 is in effect clutched to the wheel 12. Lubricant from the wheel bearings is directed by a ring 105 on the hub 21 through passages 107 in the parts 83, 88 and over the outer face of wheel 12 to the bearing surfaces of the wheel and plate 96 and escapes through apertures 96, 109. A disc 62 catches lubricant escaping from the inner end of the wheel hub and directs it to escape openings in the flat face of the drum 51. In a modified construction, passages are provided in the hub part 39 by which lubricant can flow from the chamber of the bearings 4 past the bearings 38 of the carrier 41 to the bearing surfaces between the carrier and the wheel 12. Excess lubricant escapes through openings 96, 109.

Abstract: 745,756. Valves. LEWIS, E. C. Jan. 13, 1954 [Aug. 11, 1953], No. 22086/53. Class 135. A rotary valve comprises a body part 4 adapted to be mounted in a position for use such as the wall 1 of a cask and having a bore 7 across which extends a face part 10 with one or more offset ports 15, and a valve member 8 rotatably mounted in a bore 7 in the body part and having at one end one or more offset ports 21 corresponding to and adapted to be brought into and out of register with the ports 15 on rotation of the valve member by a tubular or like key 27 one or each radial projection 28 on which is adapted to pass through a gapped flange 20 on the body part 4 to retain the key in connection with the valve member. The face part 10 consists of a disc of synthetic rubber or like material. This disc 10 and a similarly ported backing plate 11 are held against a shoulder in the body part 4 by a threaded retaining rim 12 carrying a sealing washer 121 and having notches 13 to facilitate its rotation. The body part 4 is held against a packing 14 by a notched retaining ring 5 screwed into the cask wall 1. The valve member 8 is held axially between the disc 10 and a flange 20 having gaps 29 to facilitate the insertions of the radial lugs 28 on the key 27 into gaps 30 in a flange 25 at the back of the valve member. The key can only be inserted and withdrawn in the closed position of the valve. The ports 21 are connected by inclined passages 22 to an axial passage 23 the outer wall of which is embraced by the key. The rotary movement of the valve is limited by a removable set screw 32 engaging an arcuate slot in the valve member 8. The head of the set screw 32 engages a groove 33 in the cask wall to prevent rotation of the body part 4. Rotation of the disc 10 and plate 11 is prevented by tongues 18 engaging a groove in the counterbore 9.

Title: Improvements in weft knitting machines
IPC: D04B15/32
Filed: 1966-05-18
Abstract: 1,140,839. Knitting machines. J. C. DOUGHTY. 10 May, 1967 [18 May, 1966], No. 22150/66. Heading D1C. The knitting instruments of a weft machine are remotely operated by elements which have their movements magnified whereby, comparatively, the movements of the elements result in a larger movement of the instruments. The connection between the elements and instruments may be mechanical, electrical, hydraulic or pneumatic. As shown in Fig. 1, the movement of a butt 32 on a lever 29 is transmitted to a needle 28 and by suitably positioning the pivot point 30 the needle can be caused to move an increased distance compared with that of the butt 32 operated by cam 33. Alternatively, an hydraulic piston and cylinder arrangement can be utilized to multiply the movement of the needle compared with the actuated element. In a further hydraulic arrangement, Fig. 4, fluid under pressure is caused to flow above or below a piston 37 operating a needle and the flow is controlled by valves operated by cams 44, 45 to transmit the cam movement to the needles but in a magnified form so that for a small cam movement the needles effect comparatively greater movement. Specification 952,381, 1,136,381, 1,136,382, 1,136,385 and 1,136,386 are referred to.

Title: Improvements in and relating to electric lamps embodying reflectors
Inventor: RANBY PETER WHITTEN
IPC: H01K3/00
Filed: 1956-07-17
Abstract: Method of providing a light-reflecting coating over a part of the interior surface of the envelope of an electric discharge or incandescent lamp, which may be fluorescent, comprises the steps of applying a coating of a lacquer or resin to that part of the interior surface which is not to be provided with a reflecting coating and, when the lacquer or resin coating is dry, applying to the interior surface a suspension of finely-divided reflecting material in a liquid medium which does not dissolve or react chemically with the lacquer or resin, baking the envelope, and removing, e.g. by blowing with compressed air, the reflecting material from that portion of the interior surface previously coated with the lacquer or resin, but not from the remainder of the surface.  The reflecting material can be titanium dioxide, magnesium oxide or silica.  The lacquer or resin is one which when coated with the reflecting material, renders the material non-adherent after baking.  Suitable materials are solutions of ethyl cellulose in xylene, nitrocellulose in butyl acetate, and resins of the polymerized methacrylate type in ethyl acetate. The lacquer or resin can contain a small amount of a silicone material. The suspending medium for the reflecting material may be water, and the suspension may be thickened by ammonium alginate or methyl cellulose.  In a specific example the lacquer solution is prepared by dissolving ethyl cellulose and a solution of a silicone in ethyl methyl ketone such as MS1107 supplied by Hopkins and Williams, in xylene.  The suspension of reflecting material is prepared by grinding titanium dioxide with distilled water and mixing with an aqueous solution of a propylene glycol alginate. The lacquer solution is poured into a glass tube which is held horizontal and rolled until about one-third of its surface is covered with the lacquer.  The tube is dried and the suspension of reflecting material used to coat the inner wall of the tube by pouring, spraying or welling-up.  The tube is dried and then baked to about 500-550 DEG  C.  When cool, the titanium dioxide which has not fallen from the previously lacquered portion of the tube is blown off with compressed air.  The tube is then coated with fluorescent material-by electrostatic deposition or by coating with a liquid suspension, drying and baking-and then made into a lamp.  The tube can be coated with different phosphors along its length.  Known methods of applying the reflecting material to a lamp tube are referred to.

Filed: 1924-09-19
Abstract: 238,394. Grosskopf, R. Sept. 19, 1924. Rotary machines; tripping-arrangements.-In a. printing-machine having an intermittentlyrotated impression cylinder, a pointer moving over a scale is provided to indicate when the cylinder is stationary, so that the cylinder may be thrown into and out of gear during this period if a sheet is fed to it in an out-of-register position. In a stop-cylinder machine, the printing- cylinder b is driven from the shaft a through gears a<1>, c, the latter of which engages a gear d having a cut-away portion d<1> so as to drive the impression cylinder e intermittently. Arms c<2>, d<2> on the two shafts cause the re-engagement of the gears c, d, and a roller g on a spring-pressed arm engages a notch in a drum f to hold the impression cylinder in the stationary position. To disengage the impression cylinder if a sheet is fed out of register, a handoperated lever h is provided to move the cylinder e axially and thus disengage the gears c, d. To avoid shock, the engagement and disengagement of the cylinder must be effected while it is stationary, and this period is indicated by a pointer l moving over a marked sector m and driven from the shaft b<1> of the printing-cylinder by pinions i, k. The pointer may be operated from the. shaft a or oscillated by a cam disc attached to the pinion k.

Title: Improvements relating to the spindles of yarn winding frames
IPC: B65H54/14
Filed: 1930-07-24
Abstract: 354,042. Controlling delivery in yarn winding-frames. HIBBERT, O., Windsor House, Stockport Road, Hyde, Cheshire. July 24, 1930, No. 22285. [Class 120 (ii).] In band-braking means for the spindles of yarn winding-frames, wherein the band passes over an inclined portion of the spindle, and the spindle is capable of a movement of oscillation about a horizontal axis as well as a movement of revolution, fine adjustment means are provided for moving one end of the band in a direction parallel to the axis of the spindle to allow of slight variation in the amount of the braking force applied. The spindle 1 is provided with an inclined portion 2, and is pivoted about an axis 5 in a carrier 6 which may be attached to the frame of a machine bv means of a screw 7. The spindle may thus revolve on the support 3 or oscillate about the axis 5. In operation, the spindle is mounted substantially horizontally. A double band of material 8 is arranged in frictional contact with the part 2 by looping it round a projection 10 on the carrier 6 and fastening the two ends on to a projection 9. The projection 10 is screw-threaded at 11 to receive a nut 12 which when screwed in one direction moves the band 8 up the incline 2 and increases the braking force and when screwed in the other direction allows the band 8 to slip down the incline 2 to decrease the braking force.

Abstract: 998,105. Ratchet clutches. FICHTEL & SACHS A.G. June 8, 1962 [June 15, 1961], No. 22323/62. Heading F2C. An automatic bidirectional ratchet clutch comprises two separate sets of pawls effective for opposite directions of rotation and operated by a cam disc having angular lost-motion in relation to the pawl carrier. In the arrangement shown in Fig. 2 oppositely acting pairs of pawls 5, 5a are pivotally mounted on a carrier 4 for engagement with the driven member 6, and the driving shaft 1 has a splined connection with a cam disc 3 capable of an angular displacement a relative to the carrier 4. The cam disc 3 has lobes 7 which, for clockwise drive as shown, render the pawls 5 effective for driving and the pawls 5a ineffective. When the drive is reversed the angular movement of disc 3 disengages pawls 5 and engages pawls 5a. In order to eliminate noise during overrunning a friction sleeve 11 with radial lugs 17 may be placed between the pawls and driven member 6, Fig. 6, and a ball detent 12 on the cam disc prevents undesired change in the direction of rotation. In a further arrangement, Fig. 4, the pawls 10 are mounted within and operated by cam recesses 8 in the driving disc 9.

Abstract: 693,542. Automatic exchange systems. EK, F. Sept. 24, 1951, No. 22340/51. Class 40 (iv). In a system in which each switching stage comprises sets of selectors with a controller for the operation of the selectors of each set, each controller includes apparatus which on the occurence of a wrong switching operation by a selector blocks testing operations to all selectors of the set to which that selector belongs for a predetermined time and then automatically reconnects them for operation. As shown in Fig. 2, four sets of selectors VG1-VG4 are each provided with a controller M1-M4 and a relay F1-F4. When a fault occurs in the set VG1 controller M1 responds and a momentary operating current brings up F1 which locks in series with common relay T1 and opens the test circuit for the set of selectors VG1. T1 operates, thus connecting up thermo-relay VR which pulls up and energizes T2. VR is thus deenergized and restores with delay, whereupon T3 operates over front T1 and T2 and releases F1 and T1. The set VG1 is then again available for use.

Filed: 1974-05-20
Abstract: 1507982 Microwave oscillator and frequency changer MULLARD Ltd 18 July 1975 [20 May 1974] 22477/74 Heading H3T A microwave oscillator comprises a transmission-line-resonator, means for coupling an external negative resistance device to the resonator and a variable reactance in series between the negative resistance device and the resonator whereby to adjust the operating frequency of the oscillator. A microstrip circuit is formed on a ferrite substrate using the photographic mask of Fig. 1. A Gunn diode, 1À7 mm. from the pad 1 is bonded thereto by a wire. A further wire connects pad 1 to a varactor diode mounted near the left hand end of an open circuit transmission line resonator 6. Resonator 6 is coupled capacitatively to port 3 of a gyromagnetic circulator 6, which transfers microwave energy to an antenna connected to the port 4. The received signal is transferred to the port 5 where an A.F. doppler signal is produced by a Schottky diode, the signal being extracted from port 4 via pad 22. Filters 7-11, 13-15 and 19-21, prevent microwave frequencies reaching the D.C. bias connection points 12, 18, 20. The frequency of the oscillator may be pre-set by varying the length of the bond wires to pad 1 or by removing material from the right hand end of resonator 6 with a laser. Fine tuning is effected by varying the varactor bias. A network using a thermistor is described, Fig 2 (not shown) which provides a bias that maintains the oscillator frequency constant with temperature variations. If the Schottky mixer diode is not required, port 5 is terminated by a matched load.
