Patent GB-211898-A (GB)
Title: Improvements in and relating to the testing of engineering materials under torsion
IPC: G01N3/32
Filed: 1924-02-26
Abstract: 211,898. F÷ppl, O. Feb. 26, 1923, [Convention date]. Differential governors. - The Specification as open to inspection under Sect. 91 (3) (a) states that the apparatus, which is described for testing torsional strength under repeated oscillations, may be used for maintaining constant the speed of a driving motor for any purpose. The specimen rod a is fixed at one end a<1> and carries at the other end a fly-wheel c. This is coupled by a resilient link i and a slider crank mechanism h, g, f to the shaft f<1> which is driven by an electric motor or other prime mover at a number of revolutions synchronizing with the natural frequency of oscillation of the system a, c. An eddy-current brake k is provided for regulating the amplitude of oscillation of the system a, c such brake being regulated by a stepped resistance m. The amplitude may be read by a pointer o moving over a scale n. When resonance obtains between the revolutions of the shaft f<1> and the frequency of the system a, c, the phase difference is about 90‹. Variations in this phase difference due to the frequencies not being quite in resonance, is utilized to control the motor speed. A second crank p on the shaft f<1> is connected by a linkage q, s to the fly-wheel c. Normally the pivot pin traverses the straight line r, r<1>, but when the resonance conditions do not obtain, the pin r moves along a path comprising an ellipse with r, r<1> as the major axis. The pin a carres an indiarubber wiper t which engages the periphery of a wheel u and moves the wheel together with the screw x and bridge-piece y thus varying a fine resistance v in the field of the motor, or in the case of a steam-engine being used instead of the motor, the movement of the wheel u is used to control the engine throttle valve. This application of the apparatus does not appear in the Specifi.cation as accepted.

Title: An improved temperature-sensitive device
IPC: H01H37/22
Filed: 1949-02-28
Abstract: 661,048. Thermal switches. LANDIS & GYR SOC. ANON. Feb. 28, 1949. [March 12, 1948] No. 5443/49. Class 38 (v). In a thermal switch operable by a rod- and-tube, temperature-sensitive element, an adjustable resilient member and a last-motion device are arranged between the element and the contacts so as to avoid excessive mechanical stresses in the switch. The switch. shown is of the leaf-spring micro type. The tube 1 is fixed at its upper end to a housing 3 and the rod 2 carries a pin 15 engaging a slot 14 in a sleeve 13 which is urged upwardly by a spring 12 bearing on the housing of a bevel wheel 11. A nut 16 threaded on the outside of the sleeve carries an insulating switchoperating pin 10, and is engaged with the bevel wheel 11 through pins 17, the wheel 11 being engaged by a further wheel 19 on a shaft 18. The latter has a coupling member adjustably secured to it by a screw 22 and is rotatable through an angle limited by a pin 21 and stops on the housing 3 so as to adjust the pin 10. If the switch whilst at a low temperature is to be set to switch off at a high temperature, the pin 10 is moved upwardly only until the force of the contact spring 5 equals that of spring 1.2, after which further rotation of the nut 16 forces the sleeve 13 downwards. On the other hand, if whilst at a high temperature the switch is to be set to cut off at a low temperature, the pin 10 is adjusted downwardly to compensate for the large contraction of the tube 1. In a modification, Fig. 3, the pin 10 is mounted on a nut 23 screwed into the inside of sleeve 13 which is prevented from rotation by the engagement of a lug on a fixed ring 26 in a groove 27 on the sleeve. The rod 2 has an enlarged spherical head 24 seating on a conical surface of the sleeve.

Title: Improvements in volatile anaesthetic vaporising methods and apparatus
Inventor: EDMONDSON WILLIAM
IPC: A61M16/18
Filed: 1960-02-16
Abstract: 964,414. Anaesthetic apparatus. CYPRANE Ltd. Jan. 25, 1961 [Feb. 16, 1960], No. 5446/60. Heading A5T. Anaesthetic vaporizing apparatus comprises a liquid anaesthetic container 14 carried by a body 1 through which gas passes, a wick in the container, means 7 normally shielding the wick from gas passing through the body and adjusting means 9 for exposing a variable area of the wick to the gas and thus controlling the amount of anaesthetic vapour introduced into the gas. A valve body 1 has an inlet 3 and an outlet 4 interconnected by a chamber 2. A container 14 of liquid anaesthetic is threaded to the body adjacent to the chamber 2 and has a wicksupporting stem 17 which extends from its base and projects into the chamber 2. A hollow cylindrical valve element 7 in the body has a screw-threaded operating spindle 9 which projects outside the body. The valve element may be moved to cover the projecting end of the stem 17 and to seat against a washer 6 supported on a wall 16 separating the container and the chamber 2 and thus shield the wick supported by the stem from gas passing through the valve body around the valve element. Alternatively, the valve element may be raised from its seat by an adjustable amount to expose the wick to gas flowing through the valve body. Wicks of materials having different capillarities are used according to the amount of liquid it is desired to present to the gas stream in a given time. The wick may comprise cords of loosely twisted wasted yarn depending loosely around the stem. In an alternative construction, the wick is raised from an unexposed position to a variable exposed position by operating a screw (Fig. 3, not shown).

Title: Improvements in and relating to drop hammers
IPC: B21J7/36
Filed: 1941-04-28
Abstract: 548,891. Drop hammers. CRILEY, W. W. April 28, 1941, No. 5473. [Class 83 (iv)] [Also in Group XXVI] Friction lift drop hammers have the friction lift means made operative by fluid pressure operated means with valve control capable of variable adjustment manually at will in addition to preset adjustments. The constantly running friction rolls 7 are mounted in eccentric bearings, one being adjustably fixed by a rod 11 and nuts 13 and the other connected to a piston 14 for fluid pressure operation for the lift and spring return at 17 for the release. The cylinder is connected at 39 to an axially movable valve sleeve 35 supplied with pressure fluid at 38. Slidable in the sleeve is a piston valve 30 linked at 52, 49 to a wiper 46 engaged by a cam surface on the trip and maintained against it by the weight of the parts 51, 49, 48. A further axiallymovable sleeve 40 with exhaust ports 44 is linked to a lever 60 with arms 62, 63 that tend to move the sleeve to the right, Fig. 9, by gravity. The arm 63 coacts with a fixed stop 64 to set an absolute minimum limit to the stroke; the working limit being adjustably fixed by the end of a lever 75 controlled by a link 77 secured by nuts 78 to the frame. The sleeve 35 is linked at 70, 71 to a quadrant lever 72 for manual adjustment and the sleeve 40 is controlled by a treadle 66 acting through a lever 68 acting on the arm 62, another arm 23 of the lever being connected to the eccentric bearings controlling the trip sustaining clamps 18. On actuation of the treadle the clamps are released prior to engagement of the parts 68, 62. Full stroke actuation is obtained by pressing the treadle fully down, and the length of stroke is decreased proportionately to the movement of the treadle from this position which slides the sleeve 40 towards the sleeve 35. In the position shown in Fig. 9 fluid passes by the ports 31, 32 to the cylinder and the trip rises sliding the piston to the left by means of the wiper 46 until the supply port 36 is closed and the port 37 is connected to exhaust by registration of the ports 33, 44. The control at 72 provides for adjusting the time of pressure admission to take advantage of various amounts of rebound and to provide for variations in thickness of the dies 3, 5. When making adjustments of the dies it is required to have the trip in the lowered position. To prevent burning of the lifting surfaces the lever 72 is raised to its top position closing the supply port 31 and bring- ing an arm 85 into contact with the stem 83 of a bleed-valve to open it and release the air pressure in the cylinder.

Abstract: 1,125,652. Heat treating strip material. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 6 Feb., 1967 [8 Feb., 1966], No. 5505/66. Headings F4B and F4U. [Also in Division C7] Metallic strip 12 passing through a flotation furnace is heated or cooled by jets of gas or air from apertured jet plates 13, which gas or air jets supplied from plenum chambers 7 flotationally support the strip. The jet plates 13, are adjustable so that the distance of the apertures from the faces of the strip and/or the gas flow through the apertures may be varied to give the desired heat treatment across the width of the strip. Adjustment of the flexible jet plates 13 through screw tensioning adjusters 6 produces the desired contour (e.g. 2, 3, 4 or 5) of the jet plates across the strip. The gas exits through passages 10 to atmosphere or for recirculation. In a second embodiment, the jet plates may be formed from two hinged plates, the variation of the distance from the faces of the strip being effected by variation of the hinge angle (Fig. 2). In other embodiments, the plenum chambers are divided into sections, each section being fronted by a jet plate portion, each of the sections being adjustable to vary the distanc from the face of the strip of the jet plate section (Fig. 6), or the relative dispositions of the sections may be adjusted by means of screw adjusters (Fig. 5) in each case giving the desired contour of the jet plates across the width of the strip.

Title: Process for the production of stretch yarn
IPC: D02G1/02
Filed: 1961-02-14
Abstract: Monofilament or multifilament yarn of thermoplastic organic material e.g. polyacrylonitrile, polyamide, polyester, polyolefine or acetate, is crimped by high-twisting, heat-setting, untwisting to the "normal" state of twist i.e. a twist of the order of 10-300 turns/metre (to prevent the separation of the filaments of a multifilament yarn) heat-setting the untwisted yarn under uniform tension sufficient to maintain such state, then further high-twisting in the opposite direction to the first such twisting but not necessarily to a similar extent, heat-setting, again untwisting to the normal state of twist and again heat-setting the untwisted yarn with or without tension. The second and final heat-settings reduce the twisting moment of the yarn at normal twist to zero.  The crimped yarn is stated to have stable crimp, to be free of twisting tendency and receptive of dyeing.  The initial yarn may be composite, comprising constituent yarns of similar or different construction and/or materials.  The twisting and/or untwisting may be effected continuously or in separate stages (with intermediate wind-up of twisted, untwisted and/or heat-set yarn) by means of false-twisting and/or throwing machines which may also include one or more apparatus for one or more forms of yarn heating.  Heat-setting and/or treatments may be applied to the running yarn and/or to yarns wound or winding on rollers or bobbins and the final heat treatment may be applied to the yarn in hank form.  Heating means may comprise hot air, superheated steam and/or electrically heated plate(s).  Specification 817,771 is referred to.
