Title: Improvements in fishing reels
IPC: A01K89/06
Filed: 1954-01-22
Abstract: 754,444. Fishing reels. GRICE, J. B. G. May 18, 1954 [Jan. 22, 1954], No. 2021/54. Class 48. A fishing reel has a spool carrying spindle 4 carried axially by an annular dish-shaped body 3/1 and a second spool carrying spindle 7 also carried by the body 3/1 at right angles to and of similar dimension to the spindle 4 and the arrangement is such that the spool 8 can be quickly detachably mounted in the usual. manner on the spindle 4 or in one of two positions on the spindle 7 so that the driving handles 29 can project either forwardly or rearwardly. The first spindle is a bush 4 mounted on a cover plate 2 and rotatable about a spindle 5 fixed to the body 1. The spool 8 is held on the spindle 7 or the bush 4 by a catch 10, pivotally mounted at 11 on the spool 8, pressed into engagement with a recess 9 on the spindle 4 or by means of a spring 13. The catch 10 is disengaged by a member 14, pivoted at 15 on the spool 8, on depression of one end of a lever 18 to depress the member 14 by an annular collar 17. The ends of the lever 18 project through slots 19 formed in the front and back plates of the spool 8 and the lever 18 is held central by a ball ended projection 20 engaging a radial boring in the spool bush. The spool 8 is driveably connected to the bush 4 by a spring loaded plunger 22 engaging a hole 23 in a flange 24 to which the bush 4, the cover plate 2 and a clicker wheel 25 are connected. The plunger 22 is held in position within the hole 23 by a spring clip 27. The lever 18 is counterbalanced by a screw 28. Rotation of the spool 8 when mounted on the spindle 7 is prevented by the plunger 22, or a pin 32 when the spool 8 is reversed, engaging one of a series of holes 31 in a flange 30. The teeth of the clicker wheel 25 are engaged by a clicker tooth 37 carried by a lever 34 loaded by means of a spring 36 and pivotally mounted on the body 1 at 35. A fixed stop 38 limits the penetration of the clicker tooth 37 between the teeth of the clicker wheel 25. A clicker lever 39 pivotally mounted at 40 on the body 1 and carrying a roller 41 is moved past a dead centre position to disengage the clicker tooth 37 from the clicker wheel 25.

Title: Welding apparatus
IPC: B23K9/02
Filed: 1960-01-20
Abstract: 878,547. Photo-electric control devices. L. & B. WELDING EQUIPMENT Inc. Jan. 20, 1960 [March 20, 1959], No. 2039/60. Class 40(3) [Also in Group XXII] In welding apparatus for resurfacing a row of spaced aligned workpieces, the on/off control of the welding head is effected in accordance with a row of spaced control patterns each corresponding in position to a space between adjacent workpieces and each having a range of selectible control dimensions sufficient to include the maximum and minimum spacings between the workpieces as measured in the direction of travel of the welding head. The patterns may be sensed mechanically or photo-electrically. In a machine for surfacing overlapping supports 5, attached to hinged links 3 and adapted to ride the supportng rollers of a tractor, the links 3 are held on the worktable 11 by a clamp 21 actuated through toggle linkage by a motor 27. A pair of welding heads 57 movable towards or away from each other by a handle 59 are carried by a carriage 47 suspended from a track 41. Substantially triangular patterns 71 are adjustably clamped to a member 17 on the work-table 11 at positions corresponding to the gaps between the supports 5. A light 95 and a photo-electric device 97 are mounted on an arm 113 adjustable longitudinally and transversely and carried by the carriage 47. The supports 5 are surfaced by depositing weld metal on adjacent parallel paths., Prior to welding each path, the sensing device 95, 97 is positioned to pass over the control patterns 71 at a position where the width of the patterns corresponds to the width of the gaps between the supports 5 in the path being welded, so that the sensing device stops deposition of weld metal in the gaps. When each path has been welded, the location of the sensing device 95, 97 relative to the patterns 71 is re-adjusted to correspond to the position and width of the gaps in the next path. The patterns 71 may be made of a flexible material such as rubber.

Title: Improvements in or relating to coil springs
IPC: B60T7/10
Filed: 1936-01-22
Abstract: 468,244. Springs; compensating for wear in brakes. NEATE, R. W. Jan. 22, 1936, No. 2068. [Class 108 (iii)] [Also in Group XXXIV] In a flat coiled spring the gap between the end of the outer convolution and the next convolution is obstructed by a guard in order to prevent unwinding of or injury to the spring, particularly when the spring is used as a buffer or as driving means for an angularly-movable member. The spring 1 may, as shown, be fitted to brake mechanism of the kind described in Specification 267,197, [Class 103 (i)], comprising a drum 3 rotatably mounted on a shaft 2 and connected by a cable 4 to trailer brakes, rotation of the drum in the brake-applying direction being effected by a toothed member 8 on a lever 7 rotating a toothed wheel 5 fixed to the drum, and in the brake-release direction being opposed by the spring 1 when a pawl 6 is released by the lever 7. The inner end of the spring is bent into the form of a square to engage a squared end of the shaft 2 and the outer end is bent outwardly into U-shape 10 to engage a pin 9 on the drum, and then backwardly upon itself to form the guard 11. During a normal brake application the pin 9 is rotated approximately to the position shown in broken lines. Should the pin rotate past this position, owing to increase in slack in the mechanism, it forces the guard in an anticlockwise direction and, on release of the brakes, the pin moves freely in a clockwise direction out of contact with the guard. If the slack is excessive, however, the pin rides over the guard and drops into the pocket 10, so that the slack is taken up automatically. To ensure correct positioning of the spring on the shaft 2, a slot formed in the innermost convolution may co-operate with a pin on the shaft.

Title: Improvements in and relating to acetylene generators
IPC: C10H15/02
Filed: 1955-01-24
Abstract: In an acetylene generator having a carbide hopper above a gas generating chamber, the hopper having at its lower end a valve regulating the carbide flow and controlled by the gas pressure, the valve is connected on its lower side to pressure-responsive means by an upwardly extending element situated to one side of the valve orifice.  Preferably the valve is connected to a cross-bar in turn connected to one or two push-pull rods which is or are connected to the pressure-responsive means through movement magnifying means. Also moving parts are preferably enclosed to shield them from carbide dust.  Referring to Fig. 1, a carbide hopper 1 is removably attached to a gas generator 2.  The flow of carbide is controlled by a plug 10 which is connected by a cross-bar 12 and two push-pull rods 13 through movement magnifying means to a conventional pressure-responsive diaphragm 7 controlled in turn by spring means in a casing 8. An internal casing 28 and tubes 29 protect <PICT:0829542/IV (b)/1> moving parts from carbide dust.  In the event of the plug 10 falling further than normally allowed by the pressure-responsive means, a ball 30 normally held by a catch is released due to a trigger 37 striking a ring 40.  The ball thus released blocks a hole 31 through which the carbide normally flows into the gas generator and cuts off further flow of carbide.

Abstract: 1,126,182. Delivering measured quantities of granular material. NATIONAL ENG. CO. OF CANADA Ltd. 19 Jan., 1966 [6 July, 1965], No. 2515/66. Heading B8N. An apparatus for delivering a measured quantity of material, such as sand, comprises an expansible measuring chamber 82 having an inlet portion 84, 100 and an outlet portion 88, 112 interconnected by a bellows 90 and a valve 126 actuated by a ram 142 for controlling flow through the inlet and outlet. The upper end 84 of the inlet portion is connected to the bottom of a feed chamber 42 communicating with a hopper 14 via a sliding gate valve 48. The lower end 88 of the outlet portion communicates with a delivery duct 12 which is connected by a screw 160 to a support 154 carrying a pair of guide rods 150. In order to vary the capacity of the chamber the support is raised thereby compressing the bellows, pins (152, Fig. 3) then being inserted into selected holes (150a) in the rods in order to retain the bellows in the desired position; a fine adjustment of the bellows may be effected by adjusting the screw 160. In operation, the ram 142 is actuated so that the valve 126 closes the outlet 88, material then falls from the chamber 42 into the measuring chamber. After a certain interval governed by a timer (174, Fig. 6), the ram is again actuated to close the inlet and open the outlet thereby allowing the material to be forced, by flushing air fed through a nozzle 222, into the duct 12; air is then fed via a nozzle 226 into the duct to deliver the material to a desired point. The material in the hopper 14 is assisted in flowing through the gate 48 by means of air being fed through a pair of screens 32, 34.

Filed: 1947-01-28
Abstract: 620,867. Computing-apparatus. FERRANTI, Ltd., and WALKER, D. F. Jan. 28,1947, No. 2598. [Class 106 (i)] For solving wx=yz, when x is unknown, two similar triangular electric networks are employed. Voltages differing in phase are applied across two potentiometers 1, 2, each potentiometer having two sliders. One slider 13 of potentiometer 1 is adjusted to apply a voltage proportional to w across the primary 11 of an input transformer 9 forming one side of a triangular network 8 and the other slider 23 to apply a voltage proportional to z across the primary 19 of an input transformer 21 of a second triangular network 18. A voltage pro. portional to y is applied by slider 14 to the primary 12 of a transformer 10 and a fourth voltage is applied to the primary 20 of a transformer 22. This last voltage is adjusted until a known device 27 shows that the output voltages of transformers 16 and 25 are in phase. It is proved in the Specification that when this occurs, provided the two input transformers in each network are of the same type, the value of the fourth voltage is proportional to x. Alternatively, the y and w voltage may be taken from one potentiometer and the x and z from the other, transformers 16 and 25 may be replaced by resistors and the potentiometers and transformer network may be replaced by other components.

Abstract: 1,209,681. Open-end spinning. VYZKUMNY USTAV BAVLNARSKY. 18 Jan., 1968 [1 June, 1967], No. 2769/68. Headings D1D and DIN. A break spinning device comprising an underpressure spinning chamber 1 and a combing out roller 6 for opening the fibres from a sliver 17, has the shaft 3 of the chamber 1 rotatably mounted on a rotatable hollow shaft 5 carrying the combing-out roller 6. Thus the speed of the chamber 1 may be increased while the speed of the shaft 3 relative to shaft 5 and therefore the rate of wear of bearings 4 is not. Shafts 3 and 5 are provided with pulleys 9, 10 to be belt driven. Alternatively they may be driven by separate high frequency electric motors, the rotors of which are mounted on the respective shafts. In Fig. 5 not shown the chamber (1) lies within a hollow combing out roller (6) and the air expelled through outlets from the spinning chamber passes into the hollow combing-out roller and then outwardly through apertures in the combing-out roller to assist in removal of filbres from the roller. As shown sliver 17 is fed to the combing out roller by rollers 16 driven by a chain 19. After being opened the fibres pass along a conduit 26 and into an entry conduit 22 formed in a cover 20 for the spinning unit. The fibres are thus fed to the surface of a cylindrical extension 25 of cover 20. A removable cover 21 is provided in cover 20 to enable the spinning chamber to be cleaned; cover 21 may be eccentrically mounted relative to the spinning chamber, see Fig. 7 not shown, and part of the tapering fibre entry passage 22 may be formed in it. Spinning unit; disconnecting from main drive. In Fig. 10 each spinning unit 8 is pivotally mounted on the machine frame 15 by a pin 37 carried by a vibration damping block 38. The unit is locked in its working position by a hooked lever 40 engaging a catch 39 on the unit. Normally the chamber 1 is driven by an associated pulley 9 engaging a belt 451 and combing-out roller 6 is driven by a pulley 10 engaging a belt 45. The roller 49 which co-operates with a pivotally mounted and spring biassed conductor (58) see Fig. 11 not shown, and feed sliver to the combing out roller 6, is driven from a worm wheel 50 engaging a wheel 51 on its shaft 52. If unit 8 is unlocked it pivots forward under its weight so that pulleys 9, 10 move from their belts and into engagement with braking pads 60. Alternative brake pad mountings are shown in Figs. 15, 16 not shown. 'In addition wheel 51 is moved out of engagement with worm 50 and feed roller 49 is thus stopped. Thus spinning stops. Stop motion A feeler 46 senses the thread leaving the spinning unit and on breakage actuates a signal 47 e.g. a warning light and an electromagnet 48 which displaces a clutch to stop drive to feed roller 49 and also brake the feed roller. Thus the feed of fibres to the chamber is stopped while the break is repaired.
