Title: Improvements in or relating to methods of treating rubber surfaces
IPC: B29C37/00
Filed: 1932-11-10
Abstract: Rubber surfaces such as the outer surfaces of golf balls are subjected to the action of a rubber solvent in such manner that unevenness of the surfaces is removed, and then to a hardening treatment such as vulcanization or treatment with a halide of an amphoteric element.  In an example, golf balls received from a mould are subjected to carbon tetrachloride vapour for a few seconds, or other solvents such as benzol, gasoline, butyl acetate, ethylene dichloride, and carbon disulphide may be used, or if desired the balls may be sprayed with or immersed in the liquid solvent.  After the solvent treatment the balls are dried and then subjected to the action of anhydrous tin tetrachloride in vapour form or dissolved in ethyl acetate, ethylene dichloride or other solvent.  The balls are then washed preferably in a liquid having a solvent action on the addition product of the rubber and the tin tetrachloride.  The balls are subsequently polished to provide a hard, smooth surface with a low coefficient of friction. The process is applicable to natural or synthetic rubber, crude or deresinized balata, guttapercha and similar material.  The rubber may be mixed with pigments, accelerators, colour stabilizers, and plasticizers.  Specification 384,911 is referred to.

Filed: 1953-11-17
Abstract: 731,048. Friction clutch-brake. SINGER MANUFACTURING CO. Nov. 17, 1953 [Dec. 12, 1952], No. 31867/53. Class 80 (2). [Also in Groups XXXIV and XXXV] An electric motor, comprising an inner stator 12 and outer rotor 18, has a clutch-brake disc 58, fast on its output shaft 22, and movable axially therewith to engage, leftwards, a clutch surface 62 on the rotor 18, and rightwards a brake surface 61 on an axially adjustable ring 27, the shaft being supported at the clutch end in an anti-friction bearing 45 in a cup 40, mounted in a corrugated flexible steel or copper diaphragm 38, the inner periphery of which lies in the plane of the rolling elements 45 of the bearing, said diaphragm flexing as the shaft, and its bearing move axially for clutch-brake actuation. The other end of the shaft 22 is mounted axially free in a roller bearing the inner race 24 of which is small enough to pass through its bearing cup 20, so that by removing screws 29 which clamp the end-wall 28, diaphragm 38 and brake-ring 27 to the motor housing, the entire shaft assembly including the clutch-disc 58, brake-ring 27 &c. can be withdrawn rightwards from the motor without affecting an axial adjustment of the clearance between the brake-ring 27 and the motor housing provided by screws 30, Fig. 7, which pass through clearance holes in the end-wall 28, and tapped holes in the brake-ring 27 to bear against the motor end-face, and have lock nuts which retain the diaphragm clamped on removal of the assembly. Clutch-brake actuation is by a lever 63 pivoted between ears 65 on an outer clamped member 48 of the bearing cup 40 and engaging a pin 66 on ears 67 on the end-wall 28, positively in the braking direction, and resiliently, through a leaf-spring 69, in the clutching direction. A pair of springs 72 acts on the lever 63 in the braking direction through a beam 77 adjustable by a screw 78, additional brake pressure being supplied by the diaphragm 38. Figs. 3 and 4 (not shown) use actuation by fluid-pressure supplied to the space between the diaphragm 38 and end-wall 28, which is sealed at the bearing-cup 40 by a flexible bellows. Pressure may engage the clutch and vacuum the brake, or, by the provision of a second seal at the left end of the bearing cup 40, a second pressure space may be formed to provide for pressure braking as well as clutching. Figs. 5 and 6 (not shown) provide hydraulic clutch application, by a manually moved piston in a master cylinder supplying pressure-fluid to a small cylinder carried centrally by a cap carried about the bearing cup 40 by the end-wall 28 and having a piston attached to the bearing cup 40. Four adjustable brake-engaging springs are grouped around the cylinder. In this form the actuating lever 63 is omitted, as it may also be in the previous form.

Filed: 1949-12-13
Abstract: 672,305. Electric heating elements. DAVIDSON, A. D., and SCAMMELL, E. W. Dec. 12, 1950 [Dec. 13, 1949], No. 31911/49. Class 39(iii) An electric immersion heater, comprising a tube containing a resistance unit, carries an automatic cut-out 10 and a heat-absorbing member 11 which protects those parts 1 of the tube uninfluenced by the heatabsorbing properties of the casing of the cut-out 10, and hence prevents local overheating of the tube. The member 11 may be a metal strip, e.g. of copper or silver, descending below the level of the parts 1 of the tube, or may be metal wires coiled round the tube and projecting below the parts 1, or it may be a heat-absorbing metallic body attached to the parts 1. The lower parts 2, 3, 4 of the tube do not need protection since the cut-out 10 will operate before the liquid level falls below them.

Title: Improvements in and relating to the measurement of forces
IPC: G01L11/00
Filed: 1928-11-05
Abstract: 323,591. Mason, C. C., Apthorpe, W. H., and Cambridge Instrument Co., Ltd. Nov. 5, 1928. Dynamometers; elastic - diaphragm pressure gauges.-Relates to a method for measuring a force comprising balancing the said force by a second force of which the magnitude may be regulated irrespective of the distance between the point of application of the force to be measured and the point at which regulation of the second force takes place. A lever 1 is pivoted in a frame 5 by a flexible strip 6 and the shorter end is biassed by a spring 7 whilst its other end supports a solenoid core 8 in a bobbin 9. The relatively fixed contact 12 is adjustable with respect to the frame 5 as shown and is in electrical connection therewith whilst the movable contact 11 is insulated by its supporting members 13 and 14. The frame 5 carries the insulated terminal 15 and the terminal 16 and resistance coil 17 in electrical connection with it. The force to be measured' is applied to the lever 1, for instance by connecting the diaphragm 3 to a source of pressure, and the current in the main electrical circuit comprising the solenoid 9 and the resistance 17 is increased gradually by decreasing the value of the resistance 20. Immediately the pull of the solenoid 9 upon its core 8 is sufficient to overcome the force due to the pressure on the diaphragm 3 the long arm of the lever 1 falls, the contacts 11 and 12 meet and short circuit the resistance 17 causing an instantaneous increase in the current through the ammeter 22. The value of the force measured is read at the moment of change. It is stated that the invention can also be carried out by substituting a fluid pressure system for the electrical system.

Title: Automatic control means for electrically driven mine hoisting machinery
IPC: B66B1/52
Filed: 1958-10-09
Abstract: 862,514. Controllers. SOC. DES FORGES ET ATELIERS DU CREUSOT. Oct. 9, 1958 [Oct. 18, 1957], No. 32235/58. Class 38 (3). [Also in Group XXX] A controller 44 for an electric motor driving a mine hoist is adjusted to provide acceleration and deceleration of the motor by means of a shaft 43 driven by a main shaft 1 which is subject to the movement of the hoist cages and is geared to spur wheels 14, 21, mounted on threaded portions 15, 22 of a fixed shaft 16. Hollow shafts 23, 24 are provided with abutments 27, 28 adapted to co-operate with dogs 29, 30 mounted on the spur wheels. When the hoist is moved away from a " top landing " position, the dog 29 engages the abutment 27 so that rotation of the hollow shaft 23 is transmitted to the sun-wheel 38 of a differential gear, the sun-wheel 37, integral with shaft 34, being locked by a stop 55 on a cam 46. The rotation of the satellite carrier 40 is transmitted to the shaft 43 until a spring-biased roller 50 on cam 45 enters a recess and turns the cam into a locking position. This represents the end of the acceleration period, and the controller occupies the normal-running position until the dog 30 engages the abutment 28 on the hollow shaft 24. The sun-wheel 38 is then locked by the stop 55 on cam 45, and the sun-wheel 37 is driven by the shaft 34 to turn the satellite carrier 40 in the opposite direction, and, with it, the shaft 43 thereby causing deceleration of the hoist. At a suitable moment the brakes are applied through the agency of limit switches. During a subsequent winding operation the hoist motor turns in the opposite direction, the dog 30 controlling the acceleration sequence, whilst the dog 29 subsequently adjusts the controller during the deceleration period. When the hoist is adapted for multiple-level service, the control of the motor at the intermediate stopping positions of the cages is effected by a further differential gear which has sun-wheels coupled respectively with the shafts 1 and 24. The satellite carrier is locked during the acceleration and deceleration periods by a brake controlled by a level selector, so that the shaft 24 is driven in the appropriate direction. The control of the motor upon approaching the extreme landings is effected by the dogs 29, 30, independently of the level selector and the further differential gear, Fig. 5 (not shown).

Abstract: 974,563. Fastenings. YALE & TOWNE MANUFACTURING CO. July 24, 1963 [Aug. 23, 1962], No. 32386/62. Heading E2A. A fastening for doors comprises a spring- loaded latch bolt 16, a follower 26 which, when moved angularly in one direction from an intermediate position co-operates with the bolt to provide a "dead locked" position and which when angularly moved in the other direction co-operates with the bolt to withdraw the latter, and two operating means, e.g. knobs 24 provided with locks 32, 33, adapted to be mounted on opposite sides of a door, said means having a lost motion connection with the follower 26 whereby the latter can be moved angularly to either of the two positions by either of the operating means, without moving the other means. Knob 20 is mounted on a spindle 20a bearing a cam 21 engageable with feet 17a of the bolt 16 to withdraw the bolt from the keeper 19 by rotation of the knob in either direction, steps 17b being provided to retain the bolt in the withdrawn position. A second cam 22 is mounted on the opposite side of the bolt lath and is movable through spindle 22a by knob 24. Spindle 22a supports the freely movable follower 26 bearing a peg 26a movable so that in one direction the peg 26a engages one of the feet 17a to withdraw the bolt, but in the other direction it engages stops 27 on the bolt lath 17 to prevent its withdrawal; a spring-loaded detent 28 preventing removal of the peg. A bore 29 extends through the follower 26 and is engaged by tongues 30, 31 of the respective locks 32, 33, the cross-section of the bore 29 being such that relative free movement can take place between the follower and the tongues 30, 31. When the peg 26a is in the "dead lock" position as in Fig. 4 the cam 22 can be returned to withdrawal position as in Fig. 3 without moving the follower 26. In operation, when the cam follower 26 is not in the "dead lock" position the bolt can be withdrawn by means of knobs 20, 24. When the follower is in the "dead lock" position the bolt may only be withdrawn by means of either of the key locks 32, 33. The knob 24 may be replaced by a pin tumbler lock, or the inner cylinder lock 32 replaced by a turnbutton.

Title: Improvements in or relating to apparatus for measuring relative movements or deflections of associated or interconnected parts
IPC: G01D5/347
Filed: 1939-12-18
Abstract: 537,611. Photo-electric apparatus for measuring deflections. KAPELLA, Ltd., DAVY & UNITED ENGINEERING CO., Ltd., and REASON, R. E. Dec. 18, 1939, No. 32429. [Class 40 (iii)] [Also in Group XXXVIII] Deflections of a pillar B, Fig. 3, of a press or similar structural deviations are detected and measured by a photoelectric apparatus comprising two photo-electric cells 24, 25 on which two beams of light 20, 21 are directed through two sets of apertures 13, 14 and 26, 27, one set defining sharp edges of the beams at right angles to each other, and the other set determining the amount of light passing through to the respective cells in accordance with relative alignment of the beam or beams and the structure. For example, the set of apertures 13, 14 may be mounted with the lamp 15 and accessory parts at the base of the pillar and the set of apertures 26, 27 with the cells 24, 25 may be attached to the top of the pillar. The two cells are connected through two amplifiers 34, 35 to two electric measuring instruments with scales 36, 37 at a desk 12. The various parts are adjusted so that normally the pointers of the two instruments are in the middle of their respective scales marked zero. If the top of the pillar deviates in the direction X or W, the amount of light passing through to the cell 25 is unaffected, but the amount striking the cell 24 increases or falls and the corresponding pointer moves to one side or the other of the zero of its scale 36. Similarly any deviation in the direction Y or Z is indicated on the scale 37. The optical devices may be arranged in various ways. Various specific constructions including means for making vanous adjustments are described with reference to various Figures not shown here. The light beam is interrupted by a rotating apertured disc 22, preferably in conjunction with a mask having sinusoidal apertures, to produce periodic pulsations of say 1,000 cycles per second which is suitable for amplification by three.stage amplifiers. Signalling : If the deviations reach predetermined limits indicated by adjustable red index marks 43, 431 on the scales 36, 37, relays operate to sound a signal bell 41. To ensure that the deviations intermediate between the axes WX and YZ shall not become excessive before the bell is sounded, an arrangement of three relays 38, 39, 40 is provided. These relays are connected as shown in Fig. 5. The relays 38, 40 are respectively connected across the output rectifier devices 58, 59 of the amplifiers 34, 35. The relay 39 is connected between the relays 38, 40, so that the several relays share between them the output of each amplifier. These three relays all control one relay 52 for the bell 41. If the relay 39 is given an impedance twice that of each of the relays 38, 40, the relay 52 will be operated by maximum values of deviations in all directions represented by the six-sided field shown in Fig. 6, which approximately coincides with a circle.
