Abstract: 912,506. Toothed wheels; linkwork. HUCK, W. F. Sept. 24, 1959, No. 32486/59. Classes 80 (1) and 80 (3). In a composite anti-backlash gear-wheel wherein two similar narrow gears are mounted side-by-side on a common hub and are urged by spring means in opposite angular directions, the hub 22 has a number of arms 30 to each of which is pivoted at 34 an arm 36 carrying on a single pivot 44 two links 46, 48, respectively pivoted at 50 to the two side-by-side gears 20 (only one of which is seen in Fig. 1). Each arm 36 is urged outwardly by a spring 58 seated in an opening in the hub 22 so that the pairs of links 46, 48 urge the two gears in opposite directions relatively to the hub 22. The relative movements are limited by a pin 62 carried by the hub and engaging oversize openings in the two gears.

Title: Improvements relating to bottle brushing machines
IPC: B08B9/36
Filed: 1930-11-04
Abstract: 361,571. Bottle-brushing machines. MEADOWCROFT & SON, Ltd., W. and MEADOWCROFT, W., Regent Street, Blackburn. Nov. 4, 1930, No. 33104. [Class 138 (i).] In a bottlebrushing machine, the bottles are mounted on brushes d<4> which surround a revolving central brush C. The brushes d<4> revolve about their own axes in the opposite direction to the central brush and also are intermittently or continuously rotated about the axis of the central brush. A ring brush J, which is stationary, may partly surround the ring of bottles. End stationary brushes may also be provided. The arrangement is such that when the bottles are on the revolving brushes the action of these brushes and the revolving central brush imparts a rotary motion to the bottle. If it is desired to rotate the brushes d<4> continuously around the axis of the centre brush C, plates which carry planet pinions may be driven from reduction gearing or direct from a source of power. Ratchet gearing may be used to produce intermittent rotation. The bottles may be transferred from any suitable conveyer, such as that described in Specification 360,663, [Group XXX].

Title: Improvements in or relating to welding presses operating by dielectric heating
Inventor: STANLEY EDMUND CHRISTOPHER
IPC: B29C65/04
Filed: 1958-10-17
Abstract: 856,774. Dielectric heating of plastics. RADIO HEATERS Ltd. Oct. 15,1959 [Oct. 17, 1958], No. 33251/58. Class 39(3). In radio-frequency dielectric heating apparatus for welding plastic sheet material the actuating mechanism for the electrode plunger 2 comprises a horizontal beam 1 pivoted at 17 to the plunger 2 and at 4 to the thrust rods 5 and 6, and at its centre 9 to a vertical link 8 which carries a further pivot pin 10 resting on a fixed open bearing 11. A leaf spring 12 bears on the pivot pin 10 with a downward pressure determined by the setting of a screw 14 or, alternatively, a cam. When the pedal 7 is depressed the beam 1 is rotated anti-clockwise to lower the electrode 3 into contact with the workpiece 16 and further depression of the pedal causes the beam to pivot about the point 17 and the pivot pin to rise against the pressure of the leaf spring 12. The electrode 3 then exerts a controlled pressure on the workpiece 16. A screw 18 limits the depth to which the electrode sinks in the workpiece. In another embodiment the leaf spring presses directly on the centre pivot pin of the beam and the pivot 17 is replaced by a roller fitting in a slot in the plunger to allow for lateral movement of the beam.

Title: Variable ratio gearing
IPC: F16H29/04
Filed: 1935-12-02
Abstract: 464,214. Variable speed gearing. HEJDUK, F., and NEUMANN, J. Dec. 2, 1935, No. 33347. Convention date, April 17. [Classes 80 (ii) and 80 (iii)] In a variable-ratio gear consisting of a main .transmission including a differential gear, the ratio of which is modified by a secondary transmission, the shaft of the main transmission has fitted thereon an eccentric or cam which causes oscillation of a lever which drives the secondary transmission shaft through a selflocking free-wheel friction coupling, while backward movement is prevented by an additional friction pawl. The rotary motion of any type of measuring apparatus, e.g. a liquid passage meter, is transmitted through gearing 20, 21 to a shaft 22 on which are keyed a cam 24, Fig. 4, and a wheel 23, Fig. 2, forming part of a differential gear, the wheel 37 of which is free on shaft 22 and drives through gearing 38, 40 a counting mechanism 39. The cam 24 oscillates a lever 26 free on a shaft 27 and the lever is connected to a disc 28 adapted to drive through a friction ratchet device 29, 30 a casing 32 which is connected through the shaft 27 and gearing 33, 34 with the carrier 35 of the differential. Backward movement of the casing is prevented by a detent 44. The lever 26 is urged towards the cam by a spring 43 and its throw is adjusted to vary the speed of the counting-mechanism by the use of an adjustable stop which may comprise an adjustable screw 41 on the lever coacting with a pin 421 which may either be fixed or, as shown, mounted on a member such as a thermostat 52 to eliminate the effect of temperature on the volume measured. The pin 42<1> may, if desired, be fitted with a visible indicator to show the net gear ratio. The Specification as open to inspection under Sect. 91 describes also a construction in which the secondary transmission comprises a friction disc movable across the face of a gear-wheel 4 driven from the main shaft. This subjectmatter does not appear in the Specification as accepted.

Title: Method and apparatus for filling open mouth receptacles
IPC: B65B1/26
Filed: 1955-11-22
Abstract: 786,368. Filling-machines. CARTER, C. F. Nov. 22, 1955 [April 28, 1955], No. 33426/55. Class 94(1). A device for filling containers with powder under vacuum conditions comprises means for withdrawing air from the container and two screened openings through which vacuum is alternatively applied, with consequent drawing in of limited air through the other screen for cleaning purposes. Material is fed in by. increments. The device is especially applicable to lined containers. The container C is placed on a lift plate 10 with a ring 40, having depending suction tubes 42, resting on its mouth, and with its liner L arranged over the ring and tubes. The lift plate presses the assembly against a sealing ring 35 on a filling head 12 carrying a shroud 13. The head has a central filler tube 23, vacuum connections 30 32, and atmospheric connections 31, 33. It has two separated chambers 20, 21 with screens 24, 25, each chamber having its vacuum and atmospheric connection. The shroud has vacuum and atmosphere connections 16, 17. All the connections and the filler tube are controlled by fluid pressure operated valves 1-7. At the commencement of filling, valves 1, 3, 6, 7 are open to give an air flow through both container and shroud, and then valves 3 and 7 are closed to produce vacuum inside and outside the container and draw off air through tubes 42 and orifices 41. When the desired vacuum is reached, valve 5 opens to let in an increment of material. Valves 1, 5 are then closed and valves 2, 4, 7 opened, this causing a cleaning flow of air through screen 25 into the container, and a drop of vacuum in both container and shroud. Valves 2, 7 are closed and when the desired vacuum is again established, valve 5 opens to let in another material increment. Prior to the next increment screen 24 is cleaned by opening valves 1, 3, and so on until filling is complete.

Abstract: In order that the carding action between worker rollers and a main cylinder may be less severe in the early stages of carding than later, the first worker roller has an axial spacing between adjacent rows of teeth of 1.6 to 20 mm. and each successive worker roller has a narrower axial spacing than the worker roller preceding.  The effective height of the teeth of the first and second worker rollers is preferably at least 3.5 mm. and the working angle of the teeth of the first worker roller ranges from 58 to 68 degrees with the second worker roller having a greater working angle than the first, say by 5 degrees.  Successive worker rollers may be of increasing diameters. In association with the above arrangement there may be provided a taker-in with wire clothing of less effective height than is conventional and with one or more worker rollers about its periphery (Fig. 5, not shown).  The taker-in shaft is located lower than that of the doffer roller.
