Title: Improvements relating to the projection of light
IPC: F21V7/00
Filed: 1930-07-10
Abstract: 360,910. Vehicle &c. lamps. MORSHEAD, L.' R.,'64, Victoria Street, London, and MARTIN, H., 31, Beauchamp Road; East Molesey, Surrey. July 10, 1930, No. 20904. [Class 75 (iv).] Lantern obturators; lens-holders special to lanterns.-In a vehicle lamp or like light projector a projected beam of light, which converges towards a focal point or zone, is divided into a number of portions, one of which is then formed into a concentrated beam, the remaining portion or portions being deflected and utilized for local illumination. signalling; or like purposes. For a near-side head lamp the centre of the filament of an incandescent electric lamp bulb i coincides with the centre a<1> of a hemispherical reflector b and the focus of an ellipsoidal reflector a, and a step or prismatic lens c is arranged to refract those rays of light which do not fall on the reflector a. The lens c may be mounted on seatings formed at the inner ends of radial pins h, which are screwed into a collar m surrounding the reflector a, and a radial. pin l which slides through the collar m and is screwed into a nut o which bears on a bow spring n in pin and slot engagement with the collar. The upper portion of the convergent beam then diverges downwardly and is concentrated into a flat-topped beam by means of a frontal focusing lens g, whilst the lower portion is cut off by means of a sector plate d<1> and is reflected downwardly through an aperture f<2> in the lamp casing f on to a second reflector x which redirects the light partly horizontally and partly downwardly. The reflector x may be adjusted about a vertical axis by means of a screwed pin x<1> and a wing nut x<2>, its lower portion may be slightly curved or upwardly inclined, and it may be protected from dust' by means of a frosted or clear glass front plate. The reflector d<1> may be carried by a bracket d<2> which is mounted on a screwed pin d<3> engaged by a wing nut d<4>, a spring washer or helical spring d<5> being interposed between the bracket d<2> and the lamp casing. The bracket d<2> may be, made in two parts hinged together under the action of a helical spring d<6>, the outer part being connected to a Bowden wire d<8> so that the driver may lower the reflector d<1> to provide a full beam for inspecting sign-posts and the like. The reflector d<1> may be replaced by simple or prismatic lenses and the frontal lens may be replaced by a compound lens, or by a cylindrical lens when the lamp is used as an aircraft landing light, and the flat-topped beam may be coloured by means of a glass or like filter pivotally mounted in front of the reflector d<1>. For an offside headlamp the cut off portion of the projected beam may be directed upwardly through a lens or aperture in the lamp casing, or the obturating reflector may be arranged to direct the light both upwardly and downwardly. Specification 340,522 is referred to.

Title: Method of fabricating an aeronautical propeller blade and the like
IPC: B21D53/78
Filed: 1935-07-24
Abstract: 460,237. Making screw propellers. SMITH, J. W. July 24, 1935, No. 21072. [Classes 83 (ii) and 83 (iv)] Rolling forging.-A rolled or extruded billet 10, Fig. 1A or 1D, with longitudinal flowlines is rolled out to make a propeller blade between a pair of die rolls or between a die roll 14 and platen 15 so that the metal flows along the curved lines of the finished blade from root to tip. The roll 14 is lowered and pressed in to the work by cam 50 on rotating shaft 70 bearing against the cam roller 49 to rock the shaft 53 which pulls down the link 52 and so straightens the pairs of toggles 30a, 31b, carrying the roll. A quick return oscillating beam 56 then reciprocates the platen 15 through an adjustable link 57 to roll out the work. The platen 15 is mounted on a cradle 20, Fig. 7 with an arcuate base so that it can tilt with the roll 14 to give the required twist to the blade. The roll is rotated from the reciprocation of the platen through a rack 59, Fig. 4 secured to the casing rotating the pinion 64, Fig. 7 on the roll shaft. The roll 14 is lowered further for the next pass by altering the initial angle of the toggles as follows : pin 48b is moved by hand or automatically from hook 47a to hook 47b by a rack thereby moving crank-pin 45 to alter the position of link 44 which pulls on the links 40 of the toggles to alter their angular setting from 53a to 53b. An adjusting screw 45b sets the throw of the crank-pin for the required amount of reduction of the pass. If the lever 67 is not moved the pin 48b remains in position and so the original pass remains. The machine is started by hand operated clutch 78 and performs the sequence of lowering the roll, then moving the platen to the right, lifting the roll and returning the platen. The roll and platen may be heated by automatically controlled electric elements 4 and 5 respectively, e.g. for working on aluminium or magnesium alloys. A pair of oscillating or rotating rolls may be used instead of a roll and platen.

Title: Refrigeration system provided with compressor unloading mechanism
IPC: F25B31/00
Filed: 1953-07-29
Abstract: 734,904. Fluid-pressure servomotor-control systems. CARRIER CORPORATION. July 29, 1953 [Sept. 30, 1952], No. 21081/53. Class 135. [Also in Groups XIII and XXVIII] The cold storage compartment 12, e.g. of a vehicle is cooled by the evaporator 6 of a refrigerating system including a continuouslyrunning compressor 2, and when the temperature of the compartment reaches a predetermined minimum a thermal bulb 16 closes a solenoid-actuated valve 14 in the liquid line 7, the low evaporator pressure is transmitted to the line 7 through a restricted by-pass 40 round the expansion valve 8 and this decrease in pressure is utilized to unload the compressor 2. As shown, the compressor has a plurality of cylinders each having an unloading device 20 normally held out of action by oil pressure transmitted from an oil pump (not shown) through a restriction 24 and a pipe 23. When unloading is required, the oil is bled from the unloading devices 20 through a pipe 25 and a valve 27 to the compressor crankcase. Valve 27 is normally held closed by the high pressure in line 7 being transmitted through a pipe 32 to the underside of diaphragm 29, but when valve 14 closes, the reduction in pressure in line 7 allows a spring to open valve 27. Each compressor cylinder 40 has a piston 41, an annular discharge valve 44 which is spring- loaded and an annular suction valve 35 loaded by springs 43 and disposed above a suction port 42. A sleeve 36, beneath which is disposed a stop 39, is slidable on the cylinder 40 and abuts spring-loaded rods 37, the springs 38 of which keep the rods and the sleeve in lowered position as long as the end 53 of a lever 51 is lowered. This position of lever 51 is normally maintained by oil pressure supplied through pipe 23 to the space beneath a piston 49 attached to the outer end of lever 51. When unloading is required, the oil pressure in pipe 23 is relieved, a spring 54 forces down piston 49, then end 53 of lever 51 is thus raised, the sleeve 36 is raised and the rods 37 are raised to hold the suction valve 35 in open position.

Patent GB-211229-A (GB)
Abstract: 211,229. Relay Automatic Telephone Co., Ltd., and Johnson, B. B. Nov. 17, 1922. Drawings to Specification. Automatic exchange systems; party-line systems.-In a system in which connections to a party-line are established over a common route irrespective of the particular station to be called, the ringing-controlling-apparatus for selecting the appropriate ringing-current from a plurality of such currents is not responsive to impulses but is operated in dependence upon the setting of the selecting-apparatus. The ringing-apparatus comprises a set of determining relays, each of which corresponds to a particular station on the party-line, and two synchronous distributors, the first successively connecting to a ringing-lead the different signalling currents, whilst the second, in conjunction with the operated determining relay, so controls a further relay that the ringing-lead is only connected to the called line at the intervals when the second distributor is supplying the appropriate ringing-current. In the case of calls to non-party lines, a separate signalling current is connected to the ringing-lead. The invention is described with reference to a system employing relays only which is identical with part of the system described in Specification 211,232, in which a wanted line is selected by an impulseresponder of the type described in Specification 181,119, whilst the talking connection is completed over an alternative route in the manner described in Specification 181,120.

Title: Improvements in or relating to thread detecting devices
Inventor: COOKE ALBERT EDWARD
IPC: D04B35/10
Filed: 1954-07-20
Abstract: 811,704. Knitting-machines. TRIP-LITE Ltd. July 4, 1955 [July 20, 1954], No. 21134/54. Class 74 (2). A yarn detecting device for a circular machine comprises one or more stationary guides 22 and a guide 27 mounted on a spring-loaded movable lever 26, the lever being cranked at 30 for attachment of the spring 37 which is secured to a member 33 such that the effect of the spring is least when the lever and eye 27 are in the normal yarn feeding position but which effect increases as the lever moves its eye away from the normal path of the yarn. The lever is pivoted in a casing 18 such that with the yarn in its normal position the pull of the spring on the crank passes in line with the pivot point. As the lever moves the effective leverage of the crank is increased and the spring exerts an increasing pull on the yarn. In the event of yarn failure or undue slackness the crank engages an electrical contact 38 to cause stoppage of the machine. The tension of the spring may be varied by a screw 35 adjusting the position of the member 33. If desired the lever may move in either or only one direction from the position it occupies when the yarn is feeding normally. Alternatively a weight, which may be changed, may be attached to the crank 30 or a compression spring may replace the tension spring, the crank being suitably provided to accommodate the compression spring in this case.

The stator 3 of the apparatus shown is slotted and carries a plurality of primary and secondary windings on respective teeth adjacent primary and secondary windings being separated by a tooth carrying no winding and serving to reduce the leakage flux between the windings. The rotor 2 includes teeth 10 of width substantially greater than the width of the stator teeth. The stator may include further pairs of secondary windings, the voltages in the two windings of each pair being 180‹ out of phase and the voltages in corresponding windings of different pairs being out of phase by 120‹ or any other desired angle.
Patent GB-211622-A (GB)
Abstract: 211,622. Goold, L. W., (Burroughs Adding Machine Co.). Dec. 12, 1922. Multiplying-apparatus with operating-means. -In machines of the Hopkins type such as those described in Specifications 18058/07, 18320/08, 18321/08 and 18322/08 wherein multiplying plates are utilized to determine the differential movements of the actuating ranks, means are provided for (1) ensuring the continued operation of the motor in order to effect the second cycle of operations, required whenever the multiplier is more than unity; and (2) locking the release and step-back or decimating keys during the entire multiplying operation. (1) The clutch-operating bar 38, Fig. 8, normally rests with its pin 37 in a notch 34<a> of a bar 34 slid to the left when any of the multiplier keys or the motor key is depressed. Each tens multiplying plate 9, corresponding with digits above unity, is provided with a heel 9<a> adapted, when the plate is raised at the end of the first cycle of operation, to engage an universal bail 39<a> and, by rocking it clockwise about pivots 39<b>, to actuate a link 40, bell-crank 41 and rod 42 so as to force bar 34 further forward. This causes the pin 37 to ride completely upon the horizontal edge of the bar and the latter is maintained by rod 42 in its forward position to prevent the motor from restoring it during the first cycle. (2) The release and decimating keys are connected by links with arms on a shaft 51. These arms are provided with pins 55<a> normally obstructed by the bent ends 62a of a plate 62 pivoted at 62<b>. A horizontal lever 66 pivoted at 67 bears at one end against the rear end of bar 34 so that while this bar occupies its forward position, that is, throughout the first cycle and part of the second, the lever is turned and a pawl 70 carried by its upturned end moves away from beneath a block 71 on the underside of plate 62. Consequently this plate descends and retains the pins 55<a> so that neither of the keys can be operated. The pawl 70 is held displaced by a hook 64 until the latter is again raised by the return of the operating sector 29 whereupon, lever 66 having meanwhile resumed its normal position, the pawl 70 under the action of its spring 72, now under tension due to this resumption, moves back and raises the plate 62 to inoperative position.
