Title: Improvements in or relating to sidelay mechanisms for sheet feeding machines
IPC: B65H9/10
Filed: 1946-12-16
Abstract: 619,783. Feeding sheets. BACKHOUSE, H. T. Dec. 16, 1946, No. 37065. [Class 100 (i)] In a sheet-feeding apparatus, sheets are registered laterally on the layboard by means of a reciprocating drawbar 15 with which coacts a presser roller 18 mounted in a pivoted lever 16 to which is secured a cam member 19 which is engaged by a catch 20 to hold the roller 18 out of action as the drawbar moves away from the gauge bar 34 against which the sides of the sheets are registered. The arrangement is such that the drawbar 15 can slide over the sheets without buckling them after they engage the bar 34. A chain or like member 3 oscillates a square shaft 1 which via a collar 5 and arm 6 oscillates a bell crank lever 7 connected by a link 13 to the drawbar 15, and fitted with a roller 10 which acts upon the cam 19 to control the movements of the lever 16 which operates the roller 18 and also a smoother plate 31 which is pivoted to the gauge bar and is provided with an aperture through which the roller 18 projects. Starting from the position shown in Fig. 1 in which the latch 20 has been moved out of operation, clockwise movement of lever 7 causes roller 10 to permit downward movement of lever 16 and movement of bar 15 towards the right. The smoother 31 and roller 18 move down together until a screw 37 stops the smoother. Roller 18 then descends further against the action of a spring 28 until the sheet is gripped between the bar 15 and roller 18. After the sheet is registered, the roller 10 engages the lever 16 and the roller 18 and smoother are raised and the catch 20 then holds these in raised position as the bar 15 is returned to the left. Finally, the catch 20 is released by the action of the roller 10 and the parts assume the position shown in Fig. 1 ready for registration of the next sheet. The gauge bar 34 can be angularly adjusted about a pivot 38 by means of an eccentric sleeve 41 engaging a slot in the bar and held in adjusted position by a clamping screw 43. The mechanism is supported by a bracket 22 slidably mounted on a tube 4 in which the shaft 1 is mounted, and the bracket can be given a fine adjustment by means of a screw 45 and nut 46 mounted in a clamp 47 adjustably secured to tube 4 by a screw 48. An angle section bar may replace the tube 4. In a modification, means are described for adjusting a pair of side-registering devices as above longitudinally of the feed board, and the operating chain is fitted with a rack for securing it adjustably to the lever which operates the registering mechanism. By adjustment of the screw 37 the roller 18 may be stopped before it engages the sheet, and such an adjustment permits registration of the sheets against either side by throwing out of action either one of the registering devices.

Patent GB-842763-A (GB)
Title: Conjoint halogenation technique for polyolefines
IPC: C08F8/20
Filed: 1957-12-02
Abstract: Halogenation excluding iodination but including chlorosulphonation, of aliphatic olefin polymers comprises effecting the halogenation in two stages one of which consists in subjecting the polymer directly to the action of halogen gas to provide a portion of its combined halogen content, the other step consisting in halogenating the polymer in solution to provide the other portion of its combined halogen content.  The olefin polymer may be derived from ethylene, propylene or butylene and may be an essentially linear and unbranched polymer e.g. as prepared by the low pressure process.  The direct and solution halogenation stages may be carried out as disclosed in Specification 834,905, mixtures of halogens may be employed in either of the steps and the halogenation sequence is immaterial.  In the direct halogenation the polymer is preferably in finely divided form and the temperature is kept below the sintering temperature of the polymer.  In the solution halogenation the temperature is preferably sufficiently high for at least 5% of the polymer to dissolve in the solvent and a free-radical catalyst, e.g. peroxides and azo-catalysts, or activation with actinic light are preferably also employed.  The halogenated polymer may be isolated after the solution halogenation stage by precipitation, by addition to hot water to flash off solvent or by casting as a film on to a drum drier.  In the direct halogenation stage the fluid bed technique of mixing may be used and the halogenating gas stream i.e. fluorine, bromine, or chlorine or mixtures, including mixtures comprising chlorine and sulphur dioxide, may be diluted with inert gas to improve control over the reaction.  The entire halogenation procedure may be carried out by batch or continuous processes e.g. a continuous process employing countercurrent movement of the reactants between a series of reactors.  The p  halogenated products may be moulded, spun into filaments, cast into films or formed into expanded foam structures.

Title: Improvements in clutch mechanisms for washing machines
IPC: D06F45/24
Filed: 1958-11-22
Abstract: 867,389. Washing-machines. FERNANDEZ, E. Nov. 22, 1958, No. 37680/58. Class 138 (2). [Also in Group XIII] A clutch for a washing machine of the vertical spinning tub and agitator type includes a dog clutch between the reciprocatory drive and the agitator shaft, the clutch being engaged by the action of a frictionally actuated control disc when rotation of the drive is in one direction and disengaged by its rotation in the reverse direction. As shown, pulley 11 on motor 7 drives double pulley 13, 13<SP>1</SP>, pulley 131 drives belt 16 and pulley 17, and pulley 19 drives belt 20 and pulley 21 directly connected to crank 37 which reciprocates crank 32 in the conventional way by means of a connecting rod 35. The impeller 5 is fixed to shaft 23 on which collar 24 is keyed and can slide teeth 26 into engagement with teeth 33 on crank 32 by the movement to the right of lever 44 pivoting lever 30 and fork 28 about their fulcrum 29. When the motor rotates in the direction shown by arrow 59 (Fig. 3), the rotation of the pulley 21 turns control disc 38 as shown so that its projecting arm 42 pulls rod 44, lever 30 &c. to bring teeth 33 and 26 into engagement to operate agitator 5. The spin tub 2 is not rotated because of the presence of a free-wheel device 49 between pulley 13 and driven disc 46, and also disc 46 is held by the engagement of head 56 of lever 54 in one of the recesses 48 therein. Reverse rotation in the direction of arrow 62 (Fig. 2) turns control disc 38 in the direction of arrow 63 to disengage head 56 from recess 48, the forward movement of rod 44 by arm 42 separating teeth 26 from 33 and stopping the drive to the agitator, while there is now a positive drive from pulley 13 to disc 46 which is in frictional engagement with friction disc 53 fast on hollow shaft 14 driving tub 2 at high speed for spin drying.

Abstract: 858,985. Photographic cameras. GAUTHIER G.m.b.H., A. Nov. 24, 1958 [Sept. 18, 1958], No. 37687/58. Class 98(1) In a twin lens camera in which the shutter speed and diaphragm aperture are adjusted by means of pinions meshing with gear rings concentrically arranged on the taking lens mount, one of the pinions is axially displaceable so that in one position it engages both rings to effect compensating adjustments of the shutter speed and diaphragm aperture and in the other position it only effects a single adjustment. As shown, pinion 12 is mounted on axially movable shaft 14 which is keyed for rotation with knurled operating disc 16. Spring 17 holds pinion 12 in engagement with both the shutter speed 4 and diaphragm aperture 5 gear rings which mesh with the toothed portions of scale rings 6, 7. Depression of button 18 allows pinion 12 to adjust gear ring 4 to vary the shutter speed without producing a compensating variation of the diaphragm aperture. In another form, disc 16 is replaced by a knurled disc 19 having a pin and helical slot connection with a collar 20 and the adjustments are made by turning pushbutton 18. Disc 19 provides an adjustable axial stop for collar 20 which locates shaft 14 axially by resilient engagement with shoulder 14a. Accordingly, when disc 19 is rotated to a marked end position, spring 17 is compressed and pinion 12 can only mesh with gear ring 4. Exposure valves 26 are marked on scale ring 6 and cooperate with an index 27 on ring 7.

Abstract: 379,399. Postmarking and like machines ; typewriters. POSTAGE METERS & MACHINES CO., Stamford, Connecticut, U.S.A.-(Assignees of Ogden, J. W. ; 1132, Hope Street, Springdale, and Knauer, B. ; 7, Fenwick Place, East Norwalk, both in Connecticut, U.S.A.) June 2, 1931, No. 16093. Convention date, Jan. 20. (Classes 100 (ii) and 100 (iv).] Type-wheel machines; locking-devices.-In a machine for printing and recording values, e.g. a machine for printing postage indicia of different amounts on postal packets or on adhesive strips for application to the packets and in which printing-elements in a movable printing-member are set by controlling-devices in a stationary support, the connection between the printing-elements and controlling-devices includes a channel in the printing-member which is adapted to be aligned with a channel in the stationary support to enable the printing- elements to be adjusted. The controlling devices, which are in the form of keys 1, are connected to corresponding sectors 52a adapted to be moved a distance corresponding to the number on the key 1, this movement being transmitted by a gear-wheel 49 to racks 42, 43. These parts are mounted in a casing C which also carries the main operating-shaft 41. A meter M, similar to the one described in Specification 332,918, [Class 100 (ii), Printing processes &c.], is removably-mounted on a base adjacent the casing C, and can be detached for resetting purposes. The meter contains a shaft 11 which is arranged to be engaged and driven by the shaft 41 when the meter is in position. The shaft carries the printing-drum 3 or other printing-member and actuates the adding and subtracting registers R, R<1>. The meter is also provided with racks 21, 22 which register with the racks 42, 43 and are moved therewith. The racks 21 drive gear wheels 14 connected to the registers R, R<1>, and gear wheels on a 'shaft 26. The shaft 26 carries a corresponding number of one-toothed wheels 29 each mounted in a casing formed of two complementary members which form channels 28 for the reception of a number of movable elements such as balls. A continuation of the channels is formed in the printing-drum 3, and one-toothed wheels 27 are arranged in the continuation channels, the arrangement being such that the balls &c and the two teeth of the wheels 27, 29 completely fill the channels so that movement of the wheel 29 results in corresponding movement of the wheel 27, this latter movement being communicated to a corresponding printing-element 8 mounted in the drum. When the keys 1 have been operated, to set up the correct amount of the stamp, the shaft 41 is set in rotation and rotates the shaft 11. This results in the actuation of the registers R, R<1> and the rotation of the printing-drum 3 to bring the elements 8 into printing position. As soon as the drum moves, the channels in the drum and meter are brought out of register, and the balls located in the two sections act to lock the keys and printing- elements so that fraudulent impressions cannot be obtained. In a modification, a single channel for the balls &c. is provided, and the wheel 27 is returned by a spring.
