Patent GB-459118-A (GB)
Title: Improvements in or relating to method of and apparatus for irradiating substances
IPC: A23C3/07
Filed: 1935-04-26
Abstract: An apparatus for irradiating liquids comprises means for producing an unbroken film of uniform thickness and free of solid support, said film constituting the liquid to be treated, or a barrier interposed between said liquid and the source of radiation, or both.  The uniformity and continuity of the films may be secured by counteracting the contracting tendency of surface tension by the means described in Specification 459,043, namely, (1) imparting to the liquid a velocity component along the distributing edge or slot, (2) imparting an outward velocity to annular films, (3) contacting the film with guide wires.  Fig. 1 shows an apparatus in which the liquid to be treated is distributed in an annular film 50 and separated from the central source of radiation 35 by another film 61 acting as a <PICT:0459118/III/1> <PICT:0459118/III/2> <PICT:0459118/III/3> light filter and/or a gas barrier.  The film 50 is surrounded by a reflector 106 on the lower part of which it is collected in a gas-tight manner and guided to a trough 107.  In a modification, Fig. 3, the collecting trough is divided by a wedge-shaped p  partition 125; if the liquid collects on the inner side 126 of this the gas pressure within the annular film is increased diverting the liquid outwardly to fall into the outer trough as desired.  The barrier film 61 is also collected in a gas-tight manner in an annular trough 103.  The cross-section of the films is not necessarily circular and two or more sources of radiation may be contained in the inner space.  In a modification the film or films may be projected upwardly as shown in Fig. 19.

Title: Door operator with door panel position sensing and locking device
IPC: E05F15/14
Filed: 1973-06-19
Abstract: 1408665 Door operating mechanism VAPOR CORP 19 June 1973 [9 Nov 1972] 28941/73 Heading E2M A vehicle, particularly a railway vehicle, has a horizontally-bodily-movable door 11 operated by linkwork mechanism consisting of a lower linkwork actuated by a reversible motor 17 through a gearbox 18 and output shaft 19 and an upper linkwork which freely connects the door to the mechanism base plate 14, both linkworks incorporating means for monitoring the position of the door. The shaft 19 drives an arm 20 which is pivotally connected to a crescent-shape link 21 in turn connected to one end of an arm 24 of a cranked lever 22 mounted at 23 on the base plate, the other arm 25 being pivotally connected to an arm 26. With the mechanism in the full-line over-centre condition shown in Figure 1 the door is locked in the closed position. The arm 26 comprises two parts 25, 27 pivotally connected and urged into alignment by a spring 30, thus providing a pushback movement if the door is baulked during a closing operation, the arm 27 being connected to the door by an arm 28 and link 33. The upper linkwork comprises an arm 72 pivoted at 73 to baseplate 14 and connected to the door by link 74. Limit switches 40, 41 and 42 control door movement and are actuated by elements of the lower linkage and switch 62 actuates a door signal-light circuit. A further switch 68 is actuated by a manually actuated emergency handle to prevent inadvertant operation of the actuating motor. A further switch 80 associated with the upper linkwork is actuated when the door is closed to cut-out a door-open light circuit and to complete a circuit to the vehicle traction motors, this being further associated with a door locking mechanism 88, 89, 90 and a door lock switch which breaks the door operator circuit.

Title: Vehicle tandem wheel arrangements incorporating a traction control system
IPC: B62D49/06
Filed: 1969-06-09
Abstract: 1,212,949. Adjusting loads on wheels; driving tandem axles; endless tracks. KATRAK VEHICLE CO. 9 June, 1969 [28 March, 1969], No. 28984/69. Headings B7D and B7H. A vehicle provided with two pairs of road wheels 22, 26 arranged in tandem has means to equalize the load on these wheels during braking and acceleration comprising support members 16, 18 pivotable about a shaft 14 depending from the vehicle frame 10 and on which the wheels are joumalled, and a differential having an input shaft 34 and a pair of output shafts 30 on the ends of which are wheels 34 in frictional driving contact with the road wheels, the arrangement being such. that with the members 16, 18 on each side of the vehicle locked in a fixed angular position, under acceleration, a clockwise torque set up in the differential housing will by means of a bracket 52 and resilient bars 46 tend to pivot the members 16, 18 clockwise, thus counteracting the tendency of the wheels 22 to lift. Under braking an anticlockwise torque in the differential housing will cause the wheels 26 to remain on the ground. The members 16, 18 are locked by a bolt 42 passing through plates 36, 38 rigidly fixed to said members. The members can be locked in any required angular relationship. The bars 46 are secured to the bracket 52 at 50 and the members 18 at 48. In Fig. 5 an endless track is passed round the road wheels on each side of the vehicle and driven by a sprocket wheel 54 on shaft 30. In Fig. 6 an accelerating force tends to produce a counterclockwise torque in differential housings 70 thus moving links 84, 86 to the left, pivoting a bell-crank 90 clockwise and forcing down the front of pivoted lever 78 to prevent raising of the front wheels 64. Fig. 7 (not shown) illustrates a modified form of the embodiment of Fig. 6 for unpowered wheels. In Fig. 9 under acceleration a counterclockwise torque in differential housings 164 and 186 causes fluid to pass from the rams 168 and 190 thus lengthening ram 174 and shortening ram 192 to resist lifting of the front wheels 166. Under braking the rams 174 and 192 will alter their length in the opposite manner, thus resisting lifting of the rear wheels 188. Fig. 8 (not shown) illustrates a simplified version of the embodiment of Fig. 9 employing a single ram between the unpowered axles with a further ram between one axle housing and the vehicle body.

Title: A method of spraying flat sheet-like material and apparatus for performing the same
Inventor: ZAPP GUSTAV
IPC: B05B13/04
Filed: 1958-09-10
Abstract: <PICT:0835670/III/1> In a spraying system, particularly for the spraying of flat extended pieces of material having an irregularly contoured edge, e.g. hides, the operation of each of a number of spray guns is controlled by an associated photo-electric cell sensitive to the presence of the material.  The material 2, Fig. 1, arranged on the conveyer belt 1 made of wire mesh or netting, moves beneath the spider ring 4 which has a diameter greater than the width of the material being sprayed and which is mounted for rotation about the spindle 3.  The spider supports the spray guns 6 and preceding each gun in the direction of rotation of the spider are the photo-cells 7, one being associated with each gun.  Co-operating with each cell is a light source directing light downwards towards the moving belt.  When each cell commences its sweep over the material, the light reflected by the material produces a signal in the photo-cell which switches on the associated gun, on moving off the material the absence of reflected light switches off the gun. In a second arrangement another ring is mounted below the first ring and the material to be sprayed is conveyed between the ring planes.  The rings rotate in synchronism, the lower ring has a number of light sources mounted thereon, one source being associated with each cell of the upper ring.

In an evaporator comprising a series of flash chambers A, B, C communicating with condenser spaces 27, 26, 25 respectively, maintained at progressively lower pressures by ejector pump 50, the condensate collected in trays 33, 32, 31 is cooled by passing it into chamber 75 which is maintained at a lower pressure than chamber C by ejector pump 82 so that a portion of the condensate flashes into vapour which condenses on cooling tubes 80. The cooled condensate is withdrawn through line 88. Ejector 82 exhausts into the conduit 51 connecting chamber C to ejector 50 which discharges air from the system. The apparatus may be used for the desalination of sea water which is pumped in through tubes 80 and 45. A small portion of the sea water is then returned to the sea through conduit 56, and the major portion flows through tubes 46, 47 to heater 60. The heated feed then flows through flash chambers A, B, C. Part of the brine withdrawn from chamber C is discharged from the system, and the remainder is recirculated to tubes 46, 47 through line 72.

Filed: 1957-09-16
Abstract: 819,195. Aircraft undercarriages. BLACKBURN & GENERAL AIRCRAFT Ltd., and BETHELL, B. Sept. 16, 1957, No. 29129/57. Class 4. [Also in Group XXV] A mechanical interlock for two separately movable parts, e.g. an undercarriage of an airplane and the door of a compartment into which it retracts, comprises a bell-crank lever 1 which is pivoted at 2, between side plates 17, and one end of which is shaped at 5 to latch an element 6 on the undercarriage and retain the latter until the said door is opened. The other end of the lever 1 is provided with a notch 9, between an extension or nose 10 and an opposed edge merging into a cam surface 12, and this notch is normally engaged by a T- shaped element 15 connected to a rod 13 which is mounted on the door. An extension 3 of the lever 1 is spring loaded at 4, and similarly the element 15 is subjected to loading by a spring assembly 19 acting through a pivoted plate 18. When the door is opened the rod 13 is pulled to overcome a lost motion device and rock the lever 1 to the position shown in dotted lines, whereupon the element 6 rides down the cam surface 7 so further rocking the lever 1 to its maximum extent and causing the nose 10 to displace the element 15 and rod 13. On retraction of the undercarriage, the element 6 rides on a second cam surface 8 of the lever 1 to engage the latch 5, and closing of the door returns the element 15 to the position in engagement with the notch 9.

Title: Dental impression and moulding material
IPC: A61K6/90
Filed: 1935-10-23
Abstract: A dental impression material which is a resilient solid gel at about body temperature and a plastic sol above body temperature but below 100 DEG  C. contains (1) as its principal ingredient a reversible organic aqueous hydro-colloid containing a large proportion of water, and (2) balata or a balata-like thermoplastic material having the property of repeatedly changing, on repeated heating and cooling, from a rigid state at body temperature to a plastic state above body temperature but below 100 DEG  C. and back again.  The balata may be in the hydrated condition.  The thermoplastic material may be an isomer of rubber, having the formula (C5H8)n, produced by treating rubber with sulphuric or a sulphonic acid or both.  The hydrocolloid may be agar-agar, Irish moss, or gelatin.  Thus, 20 to 40 ounces of agar-agar are dissolved in 3 gallons of boiling water, 5 to 9 fluid ounces of glycerol are added thereto, and a solution in benzol or carbon tetrachloride of the above-mentioned rubber isomer is sprayed or atomized into the strongly agitated agar-agar, a very little at a time over a long period, the agar-agar mixture being kept at a temperature of about 100 DEG  C. and the amount of solution added being such as will give 1-3 per cent by weight of isomer on the water plus agar-agar.  To the mixture may be added also potassium sulphate (which acts as a plaster-hardening agent if the final material is used for moulding plaster of Paris), oil of winter-green (as a flavouring material), a bacterici -de such as menthol, vulcanized rubber threads, waxes, resins and gums.  The final mixture is poured into a mould, allowed to solidify and coated with a cellulosic material, e.g. by dipping in celluloid.

Abstract: 409,004. Electromagnetic relays. PETER, L. H., MACGREGOR, R. M., and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Oct. 20, 1932, No. 29399. [Class 38 (v).] A time-lag relay comprising a motor mechanism arranged to be started into operation when the relay is energized or de-energized and operatively coupled to a rotary mechanism adapted to effect operation of the relay contacts after this mechanism has been rotated to a predetermined extent, has the motor mechanism so arranged as to be coupled to the rotary mechanism when the relay is energized by means of an idler pinion which under these conditions is arranged to be in operative relation to gear wheels connected to the motor and rotary mechanisms. As shown in Fig. 5, the motor mechanism comprises a self-inter'- rupting stepping electromagnet 20 shunted by a rectifier 22, energized through back contacts 28 of the relay which becomes operative when the relay is energized. At the same time a clutch magnet 35 is energized, bringing an idle pinion 33 into engagement with the pinion 32 which is driven with the toothed disc 17 stepped round by the magnet 20. The stepping round of the disc thus rotates an adjustable cam 15 and after a predetermined angular movement corresponding to a predetermined time interval the projection 16 of the cam brings contacts 11, 12 into engagement to energize the coil 9 which on attracting its armature, operates the contact arm 1. The breaking of contacts 28 breaks the circuits of the stepping magnet 20 and of the clutch magnet 35 and the making of contacts 10 completes a holding circuit for the magnet 9. In an alternative arrangement. Fig. 7 (not shown), the stepping magnet 20 may be replaced by a small synchronous motor.

Filed: 1973-06-21
Abstract: 1415578 Draw-texturing yarns HEBERLEIN & CO AG 21 June 1973 [21 June 1972] 29592/73 Headings DID and D1F In a process for draw-texturing yarn by means of apparatus including a yarn drawing means 2, 3 and yarn false twist texturing means 6, prior to commencement of the texturing operation, a reserve of slack yarn is inserted between the drawing means and the texturing means. The reserve is formed by engaging the yarn with a yarn guide between the drawing and texturing means, which guide is positioned to increase the yarn path between the drawing and texturing means and is removed prior to commencement of the texturing process, whereby the slack yarn is taken up and yarn breakages reduced or avoided. In one embodient the yarn 1 is engaged by a guide 7 mounted on a pivoted lever 8 which is moved into and out of the yarn path. In a further embodiment, the yarn is selectively engaged with yarn guides outside the yarn path and released by a spring prior to texturing. In a still further embodiment, the yarn is wrapped round a pin inserted in the yarn path, which pin is removed prior to texturing. In an alternative embodiment, a yarn guide 9 is fixed to a lever 10 which mounts pressure rollers 11 for pivotal movement towards and away from a fixed roller 12. The rollers 11 and 12 form the last delivery rollers of the drawing device and in operation the yarn 1 passes round the rollers 11 and engages the guide 9 and then passes to the texturing device. Prior to texturing the lever 10 is pivoted to bring the rollers 11 into position where the yarn engages the roller 12 and is disengaged from guide 9, a reserve of slack yarn thereby being formed between the drawing and texturing means.
