Title: Driers for road materials
IPC: F26B11/02
Filed: 1925-12-21
Abstract: 254,978. Cummer, F. H. Dec. 21, 1925. Tar-macadam, plant for making.-Relates to apparatus for drying road stone, of the kind in which the stone traverses a rotary drum 4 arranged within a stationary furnace-jacket 3. According to the invention, the outside of the drum is protected from flame by means such as spaced rings 22, Fig. 2, which rotate with the drum.

Nov. 10, 1934, No. 32452. [Class 96] Absorbent paper for towelling &c. is given high wet-strength without much loss of absorptivity by impregnating it with a dilute solution of albuminous adhesive, e.g. not more than 5 per cent of glue, gelatine, &c., and drying so as to leave thin adhesive coatings on the fibres. The adhesive may be prepared from bones, fish, hides, casein, blood albumen, &c. and may be tanned, e.g. using ¢ per cent of formaldehyde, alum, or tannic acid in a 5 per cent adhesive solution, the soaked paper being passed between squeeze rolls which allow the paper to retain its own weight of solution. A little softening material, e.g. glycerine, soap, alcohol, or preservative, e.g. sodium orthophenylphenate, may be used ; or the paper may be softened by a doctor-blade. The paper, which may be crÛped and /or embossed, may be made from kraft pulp and may be impregnated before complete drying in the paper-machine.

Abstract: 939,855. Collapsible hand carts. O. M. STANLEY. Sept. 21, 1960 [Sept. 22, 1959], No. 32470/60. Class 108(1). A collapsible wire mesh or sheet metal shopping cart comprises one or two front castor wheels 16, legs 22 which may be nested between legs 21 of a similar cart, a fixed body portion 12 having a fixed shelf 24, a shelf 32 hinged to the shelf 24 at 37, a flap 28 also hinged at 37 and which may be erected as shown to provide with the shelf 24 a seat for a child, holes 26 in the body 12 for the child's legs, and an upwardly sloping tray or receptacle 14 hinged at 15 to the body 12. When goods have been removed from the cart it may be collapsed by pushing the cart and tray 14 against a wall or the rear of a similar cart so that the tray is pivoted upwardly until it contacts lugs 36 on the shelf 32. Further pushing of the cart then pivots the tray and shelf upwardly together into the collapsed position. The shelf 32 and the back rest 28 have limited swinging movement by virtue of the construction of the hinge 37, or by provision of stops or chains, Fig. 3 (not shown), and the tray may be lightly spring biased to an open position. In the three similar cart constructions shown in Fig. 2, pivoted side members 56 in one embodiment may be opened fan wise by hooks 58 on the tray 14d, and flanges 60 are provided on the side walls 12d, to limit the movement of the members 56. In the right hand cart in Fig. 2 the tray 14a is deepened by the provision of a pivoted drop bottom pan 48 which may also be pushed up by the wall or another cart acting as an abutment. In a modification, Fig. 8, the tray is provided with an end gate 57 pivoted on a spring hinge 64, so that as goods are advanced against the gate by forward movement of a wall 66 controlled by a cord 69, the gate is pivoted down and forms a ramp. The wall 66 may be returned on release of the cord by a spring tape 72 wound on a reel 74.

Abstract: 663,158. Gas turbine plant. NETTEL, F. Dec. 20, 1949, No. 32629/49. Class 110(iii) [Also in Groups XXVII and XXXV] In a supercharger set for internal-combustion engines an exhaust gas turbine 17 drives a supercharging and scavenging blower 15. At starting, the turbine shaft is driven by an electric motor 20 or other power unit, and air from the blower being directed by a flap valve 26 into a combustion chamber 28. Fuel fed into chamber 28 by a nozzle 30<SP>1</SP> is ignited and the hot gases so formed are led into the exhaust manifold 12 and so enter the turine 17, whereupon the latter accelerates to a speed in excess of that of motor 20 which can now be uncoupled by an over-running clutch 19 and stopped. After adjusting the fuel supply to nozzle 30<SP>1</SP> in order to bring the supercharger set 14 to its rated speed a magnetic or other form of slip coupling 21 on the blower shaft is rendered operative to drive a gear train 22 and start the engine; the fuel supply to nozzle 30<SP>1</SP> now being reduced or stopped altogether and the valve 26 being adjusted to allow air from the blower to enter intake manifold 11. The mass of the rotating part of the supercharger set may be increased to facilitate starting and the flap valve and the valve 31 controlling the fuel supply to nozzle 30<SP>1</SP> may be conjointly controlled.

Title: Improvements in or relating to non-resonant antennae
IPC: H01Q11/04
Filed: 1952-12-29
Abstract: 723,513. Aerials. NATIONAL RESEARCH COUNCIL. Dec. 29, 1952 [Dec. 26, 1951], No. 32919/52. Class 40 (7). A directional non-resonant end-fire aerial comprises two radiating grids of the same size and shape, each grid being a continuous conducting member of zigzag form made up of a number of acute-angled elements disposed in succession upon opposite sides of a longitudinal axis and in a single plane, said grids being in the same or parallel planes with their axes parallel and the elements of one grid adjacent to the spaces between the elements of the other grid. In one embodiment the aerial is carried by a horizontal supporting arm 2 mounted on a mast 1. The zigzag grids are arranged in parallel horizontal planes and with their axes in the same vertical plane. One grid consists of the wire 6 arranged as shown and the other of wire 7. These wires are connected at their adjacent ends to a feeder 8 leading to a transducer 9. The other ends of the wires are either left open or shorted if the aerial is a wavelength or more long, a terminating resistor is stated to be desirable for lengths considerably under a wavelength. Each V-shaped element located wholly on one side of the axis is dimensioned according to the relationship L - d = #/2 where L is the length of the conductive path round the V, d the distance along the axis spanned by the V and # the optimum operating wavelength. The number of elements is chosen so that the vector sum of their back radiation effects is zero or nearly zero at wavelength #. However, to prevent any back radiation over the relatively wide band over which the aerial is effective a reflecting grid comprising conductors 3, 4 and 5 is provided. The supporting arrangements need not be as described and may be of metal providing they are insulated from the aerial grids. At ultra-high frequencies the elements may be placed side by side in the same plane.

The sheet 2 is formed with apertures 11 along the flow channels so that the fluids between which heat is to be exchanged are separated by only.a single thickness of metal. Marginal channels 7 for rubber packing are welded to opposite sides of the composite plates. In a modification the metal sheets are formed with apertures 12, 13, Fig. 2, and marginal packing grooves. The edges of the sheets may, however, be formed to accommodate a packing frame 24, Fig. 3. In another arrangement, the composite plate is provided with channel strips 110, Fig. 10, and packing channels 109.

Abstract: 191,925. Beever, E. Dec. 12, 1921. Table games.-A toy or game apparatus comprises two figures representing respectively a goal keeper with pivoted arms and an opponent with a pivoted leg, connected so that the goalkeeper's arms swing downwards and then upwards when the opponent's leg is drawn backwards by the operator and then allowed to kick the ball under spring action. The ball rests against a bar w which may be moved by means of a finger piece so as to adjust the ball laterally relative to the kicking leg d' of the figure d. The operator pulls back a lever i connected to the kicking leg by a spindle h, arm g and link f. On release of the lever i a spring k returns the leg and the ball is kicked towards the goal b. The goal keeper c has two pivoted arms c<1> actuated by links n, rod p, lever q, spring s and an arm t on the spindle h, the arrangement being such that the arms c<1> are lowered as the lever i is drawn back and are raised into a defensive position when the lever is released to kick the ball. A spring u cushions the downward movement of the rod p and a spring c2 limits the upward swing of the arms c'. Springs 1, 2 adjusted by screws 1<1>, 2' limit the movements of the lever q and thus allow the swing of the arms c<1> to be adjusted.
