Aeroplanes; planes, arrangement and construction of; steering, balancing, and regulating altitude.-An aircraft having one or more planes normally nested against a main plane but adapted to be separated therefrom has means for adjusting the amount of separation and also for varying their angles of incidence A monoplane is shown having a thick wing 1 attached to the fuselage at its centre bv a fin 13 and connected also to the fuselage by vertical and inclined struts 4‹, 6. A second vertical strut 5‹ connects the wing to a plate braced to the undercarriage by three struts 7, 8. Normally nested within the hollow undersurface of the wing 1 is a narrower wing 2 which can be raised and lowered by four screwed shafts 4<1>. 4", 5<1>, 5<11>, these shafts being so mounted in ball bearing sockets at each end that they are never in compression. These shafts engage screwed sockets connected by universal mountings 32, 33 to the spars of the wings 2 which have also universal mountings for smooth sockets sliding on the struts 4‹, 5‹. The mountings 32, 33 are capable of sliding on fore and aft guides connected to the wing spars to prevent binding as the plane is tilted. The screwed shafts are turned by bevel gear or by worm and screw gears, splined to the upper ends of the shafts, contained within the thickness of the wing 1 and these gears are driven by shafts 26. having universal joints 28 at intervals, extending along the wing span. These shafts 26 are driven from a vertical shaft 27, extending through the fin 13, by hand or by an electric motor or from the main motor. When all four shafts are turned simultaneously the wing 2 is moved without tilting but by differential movements of the front and rear shafts the wing 2 can be given different angles of incidence. Machines with greater wing span have additional sets of vertical struts and screwed shafts. Specification 257,280 is referred to.

IPC: G01N29/22
Filed: 1959-06-12
Abstract: 849,194. Ultrasonic inspection devices. STEWARTS & LLOYDS Ltd. June 12, 1959, No. 20134/59. Class 40(7). [Also in Group XXIX] Relates to weld testing by an ultrasonic beam in a water-filled tank through which longitudinally welded tubing passes. According to the invention the ultrasonic transducer is positioned on a mounting which carries tube-engaging means and which is on the free end of a cantilever support extending horizontally from a slide and the slide is mounted for vertical displacement on a column adjacent to the tank. Crystal transducer 15 is supported on a "search" tube 135 which is movable towards welded tubing 11 by a pinion engaging a rack on the search tube, Figs. 1 and 5 (neither shown). The search tube is oriented by worm gear 92, 95, see also Figs. 1 and 3 (neither shown), carried by shafts e.g. 55 moving in sleeves e.g. 50 mounted on a cantilever 49. Rollers 65 follow displacement of the tubing surface, limited vertical movement being accommodated by bushings 56 and limited horizontal movement by horizontal bushings, Figs. 3 and 4 (neither shown). Table 30 is rotatable and can be locked to place the cantilever over tank 140 through which the tubing to be tested runs or over tank 16 which contains a submerged tube specimen with an imposed defect in its welded seam for periodic checking and calibration of the ultrasonic apparatus. An air-operated actuator 70 lowers the cantilever which is normally in the raised position shown in Fig. 12A. Tank 140 has inner and outer sections (see Group XXIX) each having fixed pieces and movable gates e.g. 150, 155 formed by removable plates to allow for differing tube diameters, Figs. 9 and 10 (neither shown). When a run of pipe is to be welded concurrent energization of relay A causes closure of tank 140 gates after a predetermined time and subsequent filling of the tank. After a further pre-set interval air enters actuator 70 to lower the inspection device into the tank, see also Fig. 12B (not shown). To prevent damage to the device if the tubing buckles microswitch 195 de-energizes relay A. When a check with tube 13 is required table 30 is rotated manually and switch 198 is closed to cause automatic lowering of the inspection device into tank 16.

Title: Improvements in or relating to rotary brushes
IPC: B24D13/10
Filed: 1947-07-25
Abstract: 649,098. Rotary brushes; grinding and polishing wheels. OSBORN MANUFACTURING CO. July 25, 1947, No. 20168. Convention date, Dec. 13, 1941. [Classes 19 and 60] A rotary brush section comprises an annular brush-back, brushing material held in said brush-back, fabric sides embracing said brushing material and a series of circumferentially spaced radially extending means interconnecting said sides. In the drawings, the brush comprises an annular channel-form brush-back 1 carried by an adapter 2 for mounting on an arbor or mandrel. Brushing material, e.g. bristles 3 is held in the brush-back by a wire ring 4. Sheet material 5 embraces the brush material and double lines of radial stitching 6 which is continuous around the brush body draw the fabric sides together to form a plurality of pockets, Figs. 4 and 5, such pockets being effective to retain powdered abrasive or polishing material. In another form of the invention, Fig. 8. the brushing material is radially divided by a plurality of thin sheets 7 which thus divide the pockets formed by the radial stitching 6 connecting the' sheets 5. The side sheets may extend to the back of the brush or may be cut away as in Fig. 8 to provide for ventilation of the brush material. Instead of connecting the side sheets in deep scollops they may be connected by simple radial stitching 6<SP>1</SP>, Fig. 10. In another form instead of using stitching the sides may be otherwise secured together along a series of circumferentially spaced radially extending lines. Thus, adhesive may be used for securing the sides or when certain types of plastic sheet material are used, simply the application of heat and pressure along radial lines. A plurality of the annular brush sections may be assembled with the tufts of one section adjacent the radial stitching of the next, thus somewhat interlocking the same and avoiding streaking of the work. When cloth is used as siding material a plurality of layers may be used with the warps and woofs staggered to prevent unravelling and three or more layers may previously be sewed or glued together. Further, the fabric may be impregnated with lacquer, glues or drying oils such as linseed oil. Tampico fibre, sisal fibre, bristles and steel wool are mentioned as brush material whilst the fabric sides may be of woven or braided cloth, textiles, felt, paper or plastic sheet material. The Specification as open to inspection under Sect. 91, also states that the brushing material may consist of buffing cloth. This subject-matter does not appear in the Specification as accepted.

Circular rib 11a abuts the top of plug 1 to space the cap from the plug and prevent distortion of the cap when the entire top surface of the cap is subjected to pressure. Flexible strip 15 causes a warning rattle against projections 8a when cap 2 is turned without depressing area 8. An alternative embodiment (Fig. 4, not shown) provides a tear strip integral with plug 1.
Patent GB-203020-A (GB)
Abstract: 203,020. Tillander, A. E. May 2, 1922. Automatic speed or power control.-In a speedcontrol apparatus for motor vehicles in which a trip contact device is operated to break or shortcircuit the ignition circuit when a predetermined speed is exceeded and to cut off the ignition even when the vehicle slows down below the limit, the stopping of the engine is adapted to bring the trip device back to its operative position. The contact device is constituted by a lug 17 on a rod 11, a T-shaped trip member 20, and contacts 18, 19, 22. The rod 11, which is moved by the speed sensitive element 4, through a rack 12 and pinion 13 actuates an indicating drum 14, and the lug 17 moves between the lugs 24 on the member 20 until the speed limit is exceeded, whereupon it strikes the left-hand lug and turns the member 20 so as to short-circuit the ignition circuit through contacts 19, 22 and spring 23. The stopping of the engine immediately restores the parts to normal so that it can be started again. To permit the limit speed to be varied the con. tacts, instead of being supported on the casing, are all mounted in an adjustable frame 25 slidable in a guide member 26 and pivoted by means of a link 29 to a control lever 27. The lever 27 may also be connected to a signal device comprising a semaphore or the like 33 having a number of openings 36 covered by different coloured glasses and which are adapted to move past a lamp placed behind the semaphore. The rod 11 is provided with recording pen 15 adapted to trace a speed diagram on a drum 16 rotated by means associated with the vehicle-driven shaft 1. The adjustment of the contact device is recorded by a pen arm 30 which is secured to the frame 25.

Title: Improvements in or relating to steaming ovens and the like
IPC: G05D16/12
Filed: 1948-07-31
Abstract: 639,457. Steam ovens. GREEN & CO. (ECCLESFIELD), Ltd., W., and PEARSON, F. July 31, 1948, No. 20403. [Class 28(i)] [Also in Group XXIX] In a steaming oven 3 in which any rise of steam pressure is restored to normal by automatically reducing the supply of gas, such steam pressure on the water in a trough 6 drives the water out into a float .chamber 16 whereby the float 17 is raised up to operate a gas valve 22 supplying gas to the burners 8. The water level in the trough 6 is maintained by a float 7. The valve 22 has a byepass opening 32, and a stop 31 to prevent complete cut-off of the gas. The gas supply through the valve 22 at 26 is reduced only after a predetermined rise in steam pressure, such delay being provided by a lost motion head 38 and another head 33 which suspends the float 17 in the chamber until sufficient water has been forced therein to float it up. Since such ovens operate at about atmospheric pressure and are therefore of light metal, there is provided a pressure safety valve 11, and a non-return air vent to prevent a vacuum inside. The oven 3 is surrounded by a space 4 for the rising hot gases passing finally through a vent 9. Outer insulation 2 is provided. The oven is provided with tray supports 5. The gas valve head 27 mounted in a flexible diaphragm 28 is floated up to partially close an opening 26, Fig. 4, but is prevented from completely closing 26 by a downwardly projecting adjustable stop 31, a pilot hole 32, however, continuously supplies gas to a pilot jet 24 near the burners 8. Delayed action is provided in the operation of the valve by a head 33 which suspends the float 17 in the chamber 14 so that reduction of the gas supply begins only after the steam has forced sufficient water into the chamber 14 to float up the float 17. The bottom of the float chamber 14 has a drain tap 15 and a removable plug 16 for cleaning.

Abstract: 498,531. Pressure gauges. KELLY, R. D. July 26, 1937, No. 20608. Convention date, July 27, 1936. [Class 106 (ii)] Relates to the type having a reservoir of liquid exposed to a gas and means providing a path whereby the liquid may be removed against the force of gravity in proportion to the pressure of the gas, the change in mass of liquid in the reservoir being a measure of that pressure, characterized that this measurement is effected on a balance which is brought to a normal equilibrium position for each measurement. A beam 13 pivoted about a fulcrum 12 on a base 10 supported on levelling screws 11 carries on the short arm a cistern 14 containing liquid, preferably mercury 15. The long arm 16 is graduated and carries a jockey weight 17. A post 18 is provided with a mark to indicate the balanced position of the beam. A bracket 19 supports the evacuated barometer tube 20 the lower end of which is sealed by the mercury in the cistern. The column of mercury above the level in the cistern exerts no force on the beam and variations in height may be indicated by calibrating the beam. In a modification, Fig. 2, two brackets 27, 28 are provided, the one carrying the barometer tube 30 as before while the other carries a micrometer screw plunger 39 which dips into a second cistern 35 carried by the beam 34 balance of which is indicated by pointer and scale 41, 42. By screwing the plunger up and down balance is attained and barometric pressures are read on scale 43 and the co-operating graduated head 40. A further form is that shown in Fig. 1, but the cistern is carried by the base and the barometer tube by the beam. In a last form, Fig. 4, the beam 68 carrying the cistern 71 is pivoted in a gas-tight manner in the wall 62 of a chamber 61 fixed to the base and carrying the barometer tube 63. The gas to be measured is admitted to the chamber through a cock 65 while the tube 63 is exhausted through a cock 70. A partial vacuum may be measured by connecting the pipe 69 to the vacuum and the chamber 61 to atmosphere via cock 65.
