Patent GB-690931-A (GB)
Title: Improvements in hydraulic speed regulators
Inventor: GARDNER ROBERT STEVENSON
IPC: B66B1/12
Filed: 1950-01-24
Abstract: 690,931. Fluid-pressure servomotor-control systems. NATIONAL COAL BOARD. Dec. 1, 1950 [Jan. 24, 1950], No. 1811/50. Class 135 A control system for a hydraulic overspeed governor for a winding &c. engine comprises an engine-driven pump 1, ducts 2, 2a having non- return valves 3 and connected to opposite sides of the pump, a duct 6 having non-return valves 5 and interconnecting the ducts 2, 2a, pressureresponsive throttling devices 8 in each of the ducts 2, 2a, a weight-loaded adjustable leak-off valve 13 and a ram 15 slidable in a cylinder 14. Each throttling device 8 comprises a leak-off piston valve 4b urged downwardly by a weight 7b into a cylinder 9 to uncover ports 9a leading to the sump. and upwardly by the entry of pressure liquid beneath the valve through a hole 21 in the cylinder bottom. Each weight is connected to a two-armed lever 10 carrying a cam follower 22 engageable with a cam 12 mounted on a disc 11 driven by the engine. The ram 15 is held in the bottom of its cylinder 14 by springs 19b, 16d, levers 15a, 19. 17, 16, 16c and a trip catch 17a against liquid pressure in the duct 6. The lever 16c being operatively connected to the engine brake and/or the throttle valve. The operating speed of the engine, depending on whether men or freight are to be raised or lowered in the cage operated by the engine, is first set by adjusting the amount of opening of the leak-off valve 13 which is then locked in this position by wedges &c. If men, the valve 13 is moved towards its closed position so that pressure build up in the duct 6 takes place at low engine speed. If freight, the valve 13 is moved towards its open position which permits leakage to sump and hence necessitates faster running of the engine to build up the same pressure in the duct 6 to control the ram 15 and hence the engine speed. Should the engine speed rise unduly above its operating speed the piston valve associated with the pump outlet, depending on its direction of rotation, will move upwardly due to the increased pump pressure to throttle the leakage to sump whence the resultant increase in pressure in the duct 6 raises the ram 15 sufficiently to trip the catch 17a and so operate the engine brake and/or the throttle valve. When the cage is approaching the end of its travel in either direction one or other of the cams 12 rotates its lever 10 to raise the appropriate piston valve and so throttle the outlet to sump, increase the pressure in the duct 6, raise the ram 15 and again operate the brake and/or the throttle. Specification 513,176 is referred to.

Filed: 1967-01-13
Abstract: 1,166,561. Measuring visibility photoelectrically. AGA A.B. Jan. 13, 1967 [Jan. 17, 1966], No.1862/67. Heading G1A. In apparatus for measuring the effects of fog, mist, rain &c. on visibility, a beam of light is transmitted into the atmosphere and light reflected back by moisture particles such as cloud, fog, rain, snow &c., detected photo-electrically by a receiver located adjacent the transmitter, the transmitter or receiver being provided with optical elements so as to have a radiation diagram of the form shown in Fig.7. This diagram has a form according to the formula where G is the intensity of light transmitted or received at an angle # from the axis of the transmitter or receiver, # o  is the angle when the intensity is half the maximum and n is substantially equal to 2. If the transmitter or receiver has a diagram as indicated in Fig. 3 and which is obtained with a diaphragm and a collimating lens, the apparatus produces two values of visibility (on either side of a maximum) for each value of received intensity Fig.4 (not shown). The insertion on one side of the axis of the transmitter (or receiver) between the source (or detector) and the collimating lens, of either a concave mirror, with its axis substantially at right angles to this axis, Fig.5 (not shown), or a prism or cylindrical lens, Fig.6 (not shown), produces the required radiation diagram of Fig. 7 enabling discrimination between high and low visibilities.

Abstract: 976,425. Emptying containers; packaging machines. ARENCO A.B. Jan. 17, 1963 [July 9, 1962], No. 2183/63. Headings B8C and B8T. A tube-filling machine has means for directly conveying rows of tubes 17 to tube holders 36 from cartons 4 which are fed upside down on a conveyer 3, said tubes falling first into an auxiliary supporting surface 15 and then on to a main supporting surface 16. The main supporting surface is removed to allow the tubes to fall into auxiliary tube-holders 18; the auxiliary tube-holders are then spaced apart by a scissors mechanism such that each auxiliary tube-holder is above a main tubeholder 36. A second main supporting surface 34 is removed and the tubes fall into the main tube-holders, said tubes then being fed to the filling part of the machine. A row of tubes 17 resting on the main supporting surface 16 moves in the direction of motion of the conveyer and interrupts a photo-electric beam 55, which actuates a clutch 44, through which the conveyer is driven, disengaging said clutch and thus stopping the conveyer. At the same time compressed air actuates a pneumatic member 26, extending a piston 28, thus removing the main supporting surface 16 from beneath the tubes and allowing the tubes to fall into the auxiliary tube-holders. A scissor mechanism 37 is manoeuvred by means of a fork 38 and piston 39 to position each auxiliary tube-holder above a main tube-holder 36, into which the tubes fall when the plate 34 is removed by pneumatic means 35. An alternative embodiment may include a spot 58 on the carton wall which reflects a photo-electric beam, the varying intensity of the reflection actuating, in known manner, the mechanism of the machine. Furthermore, the various members may be manoeuvred by cam discs instead of by pneumatic means. Specification 895,900 is referred to.

Title: Dyeing process
Inventor: KENNEDY JOHN GEORGE
IPC: D06P3/50
Filed: 1958-01-24
Abstract: Azo dyes are formed on fabrics by treating the fabric, impregnated with a diazotised amine, with urea and then effecting coupling of the diazotised amine with a coupling component.  In one embodiment, the fabric is treated with a mixture of a diazotisable amine and a coupling component, such as betaoxynaphthoic acid or phloroglucinol, diazotisation of the amine then being effected on the fabric at a temperature below 30 DEG C., and a solution of urea applied, whereupon the temperature is finally raised to 60 DEG -100 DEG C. to effect coupling.  In another embodiment, the fabric is first impregnated with an amine which is diazotised in situ and then treated with urea, by adding it to the diazotisation bath or by applying it from a separate bath, and finally treated in a bath containing the coupling component; or as an alternative, the coupling component may be added to the separate urea bath when this is employed.  The fabric may be rinsed with acidified water after diazotisation but before treatment with urea.  The process is applicable to fabrics of polyamide, polyacrylonitrile, polyethylene glycol terephthalate, polyethylene, cellulose acetate or cellulose triacetate fibres. Examples are given.  The Provisional Specification refers also to the use of sulphamic acid, sodium acetate or a sodium acetate/acetic acid buffer instead of urea.

Abstract: 584,874. Last pulling machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS F., and WOODCOCK, R. B. Jan. 31, 1945, No- 2405. [Class 17 (i)] [Also in Group XXIV] A support which carries a shoe in a machine for removing such shoe from its last by the action of a power driven tool is moved towards the too] by the same means which control the application of power to the tool, so that the tool is rotated only when the shoe is being moved towards it, and danger t( the operative from contact with the tool is thereby reduced With this same object a guard is interposed between the tool and the shoe, the tool acting on the counter of the shoe through the intermediary of the guard. The invention is described as applied to a machine of the general character described in Specification 354,205, the treadle 32 by which the machine is controlled being connected through a lever 28 to the last pin 22 to movethe shoe towards the rotatable tool 24, substantially as in that specification. The treadle is also connected by a rod 124 to a lever 118 pivoted at 112 to the machine frame and attached at its other end, through a ring 106 in a manner to permit rotation of such disc, to the lower disc 90 of a pair of horizontal disc members 80, 90 which compose a clutch. The disc 90 on upward movement under treadle action is positively clutched to the upper disc 80 by the engagement of pins 96 thereon in axial recesses 98 in the upper disc, the undersurface of which is provided with inclined surfaces leading to the recesses 98. The upper disc 80 which is loose on the shaft 78, is continuously driven by an electric motor through gears 86. A spring 128 mounted between collars on the rod 124 serves to declutch the discs 80, 90 when pressure on the treadle 32 is released by the operative, on termination of the shoe removal operation. A guard plate 48 of rigid material covered on both sides with layers of flexible material is carried by two curved spring rods 54, 56 which are mounted in sockets 62 at one end of a table 64 fixed to the upper part of the machine, as described in Specification 406,335, to extend the guard in front of the roll 24, which may be of wood or other rigid material. The arrangement permits yielding pressure to be developed between the shoe and the roll 24 through the guard plate when the shoe is moved towards the roll.
