Title: Improvements in and relating to controlling devices for wireless sets
IPC: H03J5/00
Filed: 1929-11-16
Abstract: 335,441. Nisenson, J., and Chanin, A. Nov. 29, 1928. [Convention date]. This subject-matter was laid open to inspection under Sect. 91 of the Acts, Feb. 11, 1930]. Tuning-apparatus, control of. - A device. for automatically tuning a wireless receiving set to predetermined wavelengths incorporates means to render the loud-speaker inoperative during the tuning operation. The drawing shows an arrangement for tuning a receiver to two wavelengths by means of push-buttons 18, 18<1>. Operation of push-button 18 energizes the electromagnet 5 from the filament battery A through circuit 19, 24 and 23, thus closing contacts 14 - - 17. Closure of contacts 16, 17 connects condensers 12, 13 across the input of valve 33 and circuit L, L1 respectively, contact 14 completes the circuit of an indicator lamp 11, and 15 provides an alternative return to the battery negative for the electromagnet 5 through a resistance R and contact 20. Electromagnet 23, when energized by button 18, draws down arm 22, thus energizing electromagnet 27 which actuates arms 25 and 29 and closes contacts 25, 26 and 29, 28. Closing of contacts 25, 26 breads the return circuit of electromagnet 5, but also de-energizes 23 so that contacts 20, 22 again close and provide electromagnet 5 with an alternative return; in addition, the sound reproducer 34 is thereby short-circuited to prevent reproduction of undesired sounds. Closing of contacts 29, 28 serves to keep electromagnet 27 energized by button 18, when contacts 22, 21 re-open. To tune in a second station, button 18<1> is pressed, again energizing electromagnets 23 and 27, the former breaking the circuit of electromagnet 5, while electromagnet 5<1> inserts condensers 12<1>, 13<1> across the receiver circuits in place of 12, 13. The operation of electromagnets 23 and 27 is the same as when button 18 is depressed.

Title: Improvements relating to gas cushion vehicles
Inventor: COCKERELL CHRISTOPHER SYDNEY
IPC: B60V1/00
Filed: 1960-10-13
Abstract: 989,222. Centrifugal compressors; turbines. HOVERCRAFT DEVELOPMENT Ltd. Oct. 13, 1961 [Oct. 13, 1960], No. 35169/60. Headings F1C and FIT. [Also in Division B7] A rotor 1, Fig. 3, has a number of ports 4, formed in its cylindrical surface 5 supported by ribs 6, which extend substantially the axial length of the rotor. Air, fed through inlet 7, issues through ports 4 to form blades of air 10 which sweep around the casing 2 and thereby pump air from an inlet 8 to an outlet 9. Vanes 12 deflect the blades of air to enable them to finally move in the same direction as the pumped air. The air flowing through ports 9a and 9b may be combined, or the air from the port 9b may be collected and fed back to the energizing source feeding the air for the air blades to the rotor. Water may be used instead of air to form water blades to pump the air and the water may then be collected and fed back to the energizing means. An alternative embodiment provides at the inlet 8 a channel each side of the vanes 12, and the latter so deflects the blades of air that they leave the vanes in a similar direction to that at which they left the rotor and thereby provide a second stage of air blades. In further embodiments the vanes 12 are omitted; one such embodiment has ports 4 which extend away from the direction of rotation and may thereby drive the rotor by the reaction of the air passing through the ports. The rotor, may be so placed in the casing that the space swept by the air blades decreases from the inlet port to the outlet port. Another embodiment has a plain cylindrical rotor with ports spaced circumferentially, and air fed axially along the interior of the rotor issues radially to form blades which pump air from an axial inlet, concentric with the rotor axis, to an outlet in the periphery of a volute casing. Compressors 20, Fig. 7, generally of the type shown in Fig. 3 but without the vanes 12, are arranged on a vessel which is supported on a cushion of air. The compressors 20, supplied by ducts 32, 33 with air compressed by compressors 31, provide a curtain of air adjacent the periphery of the vessel, some of which air is recovered for re-use, the remaining portion being provided by the compressors 31 which are driven by engines 30. The compressors 20 are driven by engines 41 through chains 40 and sprockets 42, Figs. 7 and 8. The drive shafts 36 of the compressors 20 are supported in bearings 35 carried by radial ribs 37 and may be additionally supported by bearings 43.

Title: Cylindrical tool carrier for machines for chipping timber substantially parallel to the fibre
IPC: B23Q11/00
Filed: 1962-09-15
Abstract: 967,770. Woodworking apparatus. P. A. KIRSTEN. Sept. 15, 1962, No. 35251/62. Heading B5L. A wood-chipping machine comprises a cylindrical body member 10 having arranged in each of a number of peripheral recesses 36 a paring cutter 12 which, together with its holder 13, is held in the recess by interlocking adjustable means 14, 28, 29 and pressed against the wall 26 of the recess by a wedge-shaped pressure-bar 15; an insert 19 is fitted in the mouth of the recess 36 so as to be flush with the periphery of the member 10, leave a slot 24 leading to a chip-collecting space 25 in the pressure-bar, and be spaced slightly above the upper surface of the bar 15. The cutter 12, Fig. 1, which is interlocked in a recess 36 by a pair of holders 14, is set for cutting chips of depth p by a graduated adjustment screw 30 acting on each holder 14 which, after adjustment is locked in position by a screw 29. The pressure-bar 15 is spring- pressed outwardly to clamp the cutter and holder against the wall 26 and also the depending leg of the insert 19 against the wall 27. The cutter 12, Fig. 5, is inclined to the axis of the carrier 10 while in front of each cutter are several side-by-side scoring cutters 31 which determine the axial length of the chips, the length being such that the chip in its axial length will bridge the width of the inclined slit and pass into the space 25. These scoring cutters 31, shown in Figs. 5 and 10, are finely adjustable similarly to the paring cutters and are secured at equal distances apart in a plate 51 which is supported by a pre-adjusted stop 56. Chips collected in the spaces 25 may be blown out by compressed air fed from the central shaft of the carrier; alternatively, air may be blown into the space as shown in Fig. 5 by means of vanes 39 carried for rotation with the member 10; the chips are arranged to be evacuated in each case after the space 25 has left the chipping zone. In the embodiment shown in Fig. 8a, the chips are blown out in the axial direction, vanes 45, 49 then circulating the air while ribs provided on the casing 50 loosen chips that are jammed and an extra air blowing device 147 directs compressed air into the space from a central shaft 150. Instead of providing scoring cutters 31 to determine the length of the chips to be cut the same effect may be obtained by using cutters 12 having stepped or interrupted cutting edges.

Patent GB-418943-A (GB)
Title: Improvements in or relating to processes of making vinyl esters
Filed: 1933-12-18
Abstract: Vinyl esters are manufactured by reacting acetaldehyde, preferably in the form of paraldehyde, with an aliphatic carboxylic acid anhydride by heating the mixture and continuously distilling off the vinyl ester.  The reaction may be carried out in the presence of a non-volatile inorganic acid catalyst, e.g., sulphuric, phosphoric or toluenesulphonic acids, preferably in amount between 0,25--2 per cent.  In examples: (1) acetic anhydride and paraldehyde are boiled in the presence of sulphuric acid, the volatile products being removed through a fractionating column and the distillate refractionated several times to yield vinyl acetate; (2) the same reaction mixture is boiled in a flask connected for simple distillation, the vapours being introduced into a continuous still near the middle of the column; a mixture of vinyl acetate, acetaldehyde and acetic acid passes over and is fractionated after adding copper acetate and sodium acetate, whilst higher boiling and unreacted materials collect in the still kettle and are returned to the reaction vessel; (3) the reaction mixture is heated as in (2) and when the still head temperature reaches 133 DEG  C. a further quantity of reagents is added continuously; the distillate is fractionated as in (2), whilst high boiling bye-products accumulating in the reaction vessel are removed by drawing of portions of the reaction mixture into a tar pot from which volatile products are returned to the reaction vessel; (4) the procedure is as in (3) except that the vapours are led into a continuous still provided with a tray-containing column, whence the higher boiling constituents are returned to the reaction vessel, whilst the vapours pass into a second continuous still where they are fractionated into a heads-cut containing vinyl acetate and acetaldehyde, and a tails-cut containing acetic acid and anhydride; these fractions are then fractionally distilled.  The paraldehyde may be replaced by the equilibrium mixture of acetaldehyde and paraldehyde obtained by treating acetaldehyde with sulphuric acid, or the similar mixture found when the recovered acetaldehyde stands in contact with accompanying traces of sulphur dioxide. Vinyl propionate and butyrate may be similarly produced.  Reduced pressures may be employed, especially when making the higher boiling esters.

Title: Improvements in or relating to apparatus for drying and heating ores, stone, slag, and other materials
IPC: F26B17/14
Filed: 1937-12-23
Abstract: 504,956. Rotary - scraper drying apparatus for stone, ores, or slag PRIEST, C. F. Dec. 23, 1937, No. 35638 [Class 34 (ii)] Stone, slag, ores, e.g. small iron ore and other materials, are dried in a fixed vertical casing 10 having on its inner side a series of ring trays 12 with central orifices 13 coaxial with the casing, in which is placed a rotary central shaft 14 carrying disc trays 29 alternating with the ring trays, so forming annular spaces alternately at the shaft and casing; scrapers 34 on arms 33 on the shaft 14 engage the upper surface of the disc trays 29 and scrapers 32 on arms 31 on the casing engage the ring trays 14 so that material fed in at a top hopper 35 is passed down the casing, to which hot air is supplied at the top and other levels and is withdrawn at the bottom. The inclination and spacing of the frusto-conical trays decrease progressively downwards. The scrapers 34 may be tangential to the orifices 13 and are twisted at the ends. Material passes from the hopper 35 to a table 37 with supports 39 and a fixed cone 48, from which material is discharged through an annular space 38 to the trays by scrapers 43 rotating on arms 42. A vertically adjustable ring 51 regulates the feed to the table. Burnt gas from furnaces 60 passes up through pipes 61 with ducts 62, 66 having dampers 63, 67 into the casing ; some gas passes into a space 50 round the hopper 35 through holes 64 into the casing, whence all the gas is withdrawn at the bottom through an exhaust flue 65 in a discharge hopper 59. Cool air may be added to the hot gas through inlets 68 with dampers 69. The material falls at the bottom into a conical vessel 56 and hence through apertures 53 in the lower end of the hollow shaft 14 into a discharge hopper 59 and shoot 72 with a rotary sealing valve 73 to an elevator 74. The shaft 14 is rotated by a motor 24 and carries on radial arms 15 horizontal and vertical wheels 16, 19 running on tracks 17, 20.
