Title: Improvements in friction clutches and in gears embodying them
IPC: F16H3/66
Filed: 1946-09-03
Abstract: 625,318. Change-speed epicyclic gearing. CLERK, R. C. Sept. 3, 1946, No. 29174/47. Divided out of 625,277. [Class 8d (ii)] In a change-speed gear having at least two threeelement planetary gear trains controlled by an electromagnetically-operated friction clutch and at least two electromagnetically-operated friction brakes, one of the brakes, which compounds the trains to bring in the lowest gear ratio, is of the torque-assisted type. As shown, applied to a four speed and reverse gearing, a primary train A having its annulus A8 and planet carrier A6 connected to the driving and driven shafts 10, 11 respectively has a reaction sun A5 carrying the armature 15 of a combined electromagnetic clutch and brake, the clutch coil 12 of which is secured to the annulus A8 and 20 gives a direct drive through the gearing on engagement. Disengagement of the clutch and stationing of the armature 15 by the co-acting brake 3 gives third speed. For second, first and reverse speeds both the clutch 12 and brake 3 are released and the primary train A is cummulatively compounded, by the alternative operation of electromagnetic brakes 2, 1, R, with further gear trains B, C, D of mutually equal gear sizes and having, as far as possible, standardized interchangeable elements. The trains B, C have annuli B8, C8 connected to the driven shaft 11, planet carriers B6, C6 secured to the armatures 16, 18 of brakes 2, 1, and suns B5, C5 rotatable with the sun A5 and carrier B6 respectively, whilst the train D has an annulus D8 secured to the armature 21 of the brake R, a planet carrier D6 connected to the driven shaft 11, and a sun D5 rotatable with the armature 18. The brakes R. 1 are of the torqueassisted type described in the Provisional Specification and in Specification 625,277, and the brakes 1, 2, 3 and clutch 12 are of the kind described in Specification 599,462 having auxiliary synchronizing magnets 1S ... 4S. In the event of electrical failure, an emergency mechanical third speed may be engaged by screwing a bolt 40 through the gear casing to engage a peripheral notch in the armature 15. The clutch coil 12 is energised through a slip ring 13 and carries a vaned rotor 23 which picks up oil from the casing floor and delivers it through a gallery (not shown) to a duct 26 lubricating the trains through bores 28 ... 34 in the shafts 10 and 11. In Fig. 2 (not shown) an overdrive is added by interchanging the driving connections of the primary train and introducing an additional train between it and the secondary train having a sun connected to that of the primary, a planet carrier on the driven shaft and a brakeable annulus secured to the sun of the secondary train. In Fig. 3 (not shown) this arrangement is converted to a fourspeed gear by omitting the first speed train. Specification 597,563, [Group XXXII], also is referred to in the Provisional Specification.

Abstract: 469,530. Golf clubs. WETTLAUFER, W. L. Oct. 28, 1936, No. 29298. Convention date, Oct. 29, 1935. [Class 132 (ii)] In a golf club means are provided for adjusting the shaft in its relation to the toe and striking-face of the head without changing substantially the inclination of the shaft to the striking-face. In one form of the invention, the head 1, which may be formed with a plurality of ducts 5 ... 10 containing mercury, has a tapered socket 16 engaging the spindle 15 of a shank 3 in which is secured the shaft 2. The axis of the shaft 2 is offset relatively to the axis of the spindle 15, so that the requisite adjustment of the shaft along a circular path 17 is secured by rotating the shank on the head, the parts being subsequently locked in position by a screw 22 causing ribs on a flange 18 to engage recesses in the head. Fig. 10 shows a construction wherein the adjustment is made by turning the offset portion 31 of the club shaft 30 in the head socket, four bayonet slots 34 providing four locking positions. In another construction, the head socket and the offset shaft have each a square section to provide the four locking positions. In a further modification, Figs. 18 and 20, the shaft 51 is inserted in a selected socket in the head 45, a number of such sockets 47 ... 50 being provided. A shank 54 carries a tube 55 engaging one of the unoccupied sockets.
Patent GB-294227-A (GB)
Abstract: 294,227. Kßrpßti, J., and H³bsch, M. G. July 21, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Acetaldehyde.-In the production of acetaldehyde from acetylene, the acetylene and the sulphuric or acetic acid absorption medium are separately maintained in circulation systems having in common the reaction chamber in which the absorption medium falls in coherent thin streams. In an example, sulphuric acid of 25 per cent containing mercuric sulphate as catalyst is fed from a vessel 2 to the reaction chamber 1 from which it is drawn by a pump 7 through a heating-tube 16 to a distributor 9 which forms the thin streams. Mercury sludge collects in a recess 22 of a collecting tank 6 containing a thermometer 17. Water is fed from a vessel 4 to a chamber 3 and is drawn by a pump 10 through a pipe 12 to a distributor 13. Acetylene is supplied by a pump 14 and pipe 15 to the bottom of the chamber 1 and passes out through a reflux condenser 18 and pipe 19 to the bottom of the chamber 3 where it meets the washing water which dissolves the acetaldehvde. The acetylene freed from acetaldehyde is returned to the pump 14. Sulphuric acid of concentration above 45 per cent., such as 50-55 per cent, may be used. When acetic acid is employed, 0.1 to 0.2 per cent of sulphuric acid may be added. The temperature may be above 50‹ C. such as 70‹ C. The solution of acetaldehyde obtained may be of such strength that the aldehyde may be separated by salting out.

Title: Feeder mechanism for labelling machines
IPC: B65C9/14
Filed: 1972-06-23
Abstract: 1394907 Label feeding JOHANN WEISS MASCHINENFABRIK UND APPARATEBAU GmbH 23 June 1972 [20 July 1971] 29523/72 Heading B8F A label feeder machanism, which transfers labels 16 from a container 3 to a gumming drum 6, includes a feeder 4 having arms the ends of which describe an epicycloidic path, whereby a label 16a is picked up at one outer reversal point 17a of the path, transferred first to a rotating drum 5 midway between point 17a and the next outer reversal point 17b, and then to the gumming drum 6. The feeder 4 is fixed to a planet gear 23 which meshes with a fixed ring gear 22, and the shaft 21 of the planet gear is rotably mounted on the crank arm of a shaft 20 which is coaxial with the ring gear. Rotation of shaft 20 causes the ends 19 of the feeder 4 to move in an epicycloidic path with outer reversal points every 72 degrees and with a transmission ratio between the ring gear and the planetary gear of 1À25 : 1. The feeder 4 has suction apertures 18 in the ends 19 of its arms and the vacuum supply to these is controlled by a fixed valve plate 26 having a series of apertures 57 of varying sizes connected to a vacuum source, and a bronze rotary valve plate 25, having apertures 39, which is rotated with the shaft 20. The arrangement of the apertures is such that maximum suction occurs at apertures 18 at the instant of transfer of a label to the feeder and that the vacuum is shut off at the point of transfer to the drum 5 which also has suction apertures. A spring 29 holds the valve plates 25, 26 against the feeder 4. The outer reversal points of the epicycloidic path are loop shaped giving a small circumferential movement component at the moment of transfer to assist removal of a label 16 from the container 3. These loops are obtained by arranging that the ends 19 of the feeder arms are offset radially inwards of the pitch circle of the ring gear 22. After transfer to the gumming drum, supplied with gum by unit 7, the label is transferred by a stripper 13 to a suction belt 2, and then applied to bottles 8 rolling between the belt 2 and a sponge rubber surface 11. Prior to labelling the bottles are equally spaced on a conveyor 10 by a worm 9. Instead of the label-applying belt 2, a labelling cylinder may be employed. The labels may be front and/or back dated by devices adjacent the gumming drum 6 and the belt drum 1 respectively.

Title: Improvements in or relating to absorption-refrigerating apparatus
IPC: F25B15/10
Filed: 1939-11-15
Abstract: 536,384. Refrigerating. ELECTROLUX, Ltd. Nov. 15, 1939, No. 30162. Convention date, Dec. 14, 1938. [Class 29] Absorption systems.-In continuous-cycle inert gas systems having a pressure vessel 30 in the inert gas circuit, refrigerant condensed in the pressure vessel under'high cooling-air temperatures is utilized for rectifying vapour flowing between the generator 10 and the condenser 16. The vapour pipe 11 beyond the usual finned rectifier portion 12 is led into a vessel 13 supplied with condensate from the pressure vessel by a seal pipe 34 and connected by a conduit 14 to the condenser. The pressure vessel is connected by a pipe 31 with the gas heat exchanger 20 and by a pipe 32 with the pipe 17 'through which condensed refrigerant is supplied to the evaporator 18, 19.. Under normal conditions the pressure vessel contains inert gas, which is displaced by uncondensed refrigerant vapour from the condenser under high cooling-air temperatures. This vapour condenses in the pressure vessel, which may be finned, and flows into the vessel 13 where some of it is stored out of circulation, thus reducing the concentration of the solution and facilitating absorption.

Abstract: 700,625. Endless conveyers. FAIREST, Ltd., M. Nov. 21, 1951 [Dec. 11, 1950], No. 30220/50. Class 78 (1) [Also in Group XV] In a labelling machine cylindrical objects, such as bottles, travelling on an endless conveyer are engaged by a resiliently mounted endless belt to rotate them about their axes. The objects 2, Fig. 1, are spaced by a worm 4 on a conveyer 3 and pick up labels from boxes 6. A vertically adjustable arm 17, Fig. 2, on a driving shaft 18, driven by a motor not shown, carries a vertical shaft 16 driven by a chain 19 from the shaft 18, on which is a driven pulley 15 for a belt 7. Also mounted on the shaft 16 is a triangular frame 26 having an extension 27 from its apex to which a link 28 parallel to the arm 17 is connected so that the front of the frame 26 as it swings about the shaft 18 remains parallel to the conveyer 3. The frame 26 is urged towards a guide bracket 40 so that the belt 7 extends through a hole therein. The belt 7 passes round the driving pulley 15 and pulleys 29 fixed to the corners of the frame 26 and is tensioned by external pulleys 30 on arms 31 pivoted to the frame 26 and urged against the belt by a turn-buckle 33 on a divided connecting rod 32. Bell-crank levers 35 pivoted at 36 are engaged by spring-loaded plungers 37 to urge guide pulleys 34 against the belt 7. Pulleys 39 on fixed pivots on the frame 26 may be positioned opposite the gap between the delivery boxes 6 to divide the operative run of the belt 7. Thus the springs 46 resiliently keep the belt 7 extending through the hole in the guide bracket 40, while the guide pulleys 34 resiliently urge it into contact with each object opposite a box 6 allowing for small variations in successive objects. The guide plate 40 may be adjusted to and from the conveyer 3 for different sized objects by a handwheel 42, while a handwheel 25 gives adjustment for the height of the label application.
