Title: Improvements relating to dobbys for looms
IPC: D03C1/04
Filed: 1961-09-22
Abstract: 988, 690. Dobbies for looms. A. W. OMAR. Sept. 22, 1961, No. 34039/61. Heading D1E. A loom dobby comprises a number of operating rods 1 to each of which at their end 3 is attached a harness of heald cords. The rods 1 are selectively actuated by a reciprocating driving member 4 driven from a shaft 31 under control of a pattern drum 10 with pegs 11. The pegs 11 are adapted, through double lever devices 12, 12a, to engage selected clutch members 6 on member 4 with tongues 9 on the rods 1 to move them to the left against spring pressure to be held by retaining members 14 engaging in recesses 17. The selected rods 1 are thus held to the left whilst the driving member 4 makes its return stroke and is retained there as long as a fresh peg 11 is presented to the double lever 12, 12a on successive steps of the pattern drum 10. In the absence of such a fresh peg 11 the rod 1 is released and this is effected by a second reciprocating member 22 driven from the shaft 31 out-of-phase with the driving member 4. The member 22 carries a lever 21, 19 pivoted at 20a which, when the member 22 is moved to the left, engages with an abutment 25 which pushes the part 19 down to engage a tongue 26 on rod 1. The rod 1 is thereby moved slightly further to the left and unless retaining member 14 is held up by a peg 11 it falls and allows the rod 1 to return under its spring pressure to the right. This return movement is controlled by the return movement of member 22, the tongue 26 acting against the part 19 of lever 21, 19 which is released when member 1 moves against a stop.

Abstract: 205,736. Wade, H., (Lockwood, L. V.). Dec. 14, 1922. Blowing.-A bottlemaking machine comprises the combination of a mould - carrier carrying a series of invertible moulds in an orbital path with a neck - screwing device carried by each mould. The threaded shank of the screwing mandrel passes through a nut mounted in a tubular member which interlocks with the neckmould section and rotates with the mould. Each mould B<2> comprises a pair of main mould sections 3 and a pair of neck-mould sections 3<a>, each pair meeting in a vertical plane and being provided with arms 3<c> and 3<b> respectively. The inner ends of these arms are pivoted at 4 to a face-plate 1<a>, and links 8<a> connect the arms with a plunger 8 passing through a trunnion 1 journaled in a bearing box 2 which is secured to the rotating table B. The inner end of the plunger 8 carries a roller 8b engaging with a cam C carried by the centre column A<1> of the machine. Thus the mould B<2> is caused to open as the table B moves round the column A'. The neck-mould sections 3<a> interlock with a tubular member 5<b> which carries a nut 5 through which passes the shank 10 of a hollow, screwed mandrel E, the upper end of which is provided with a threaded tip 10<a>, adapted to project into the neck-mould. A gear-wheel E<1> secured to the mandrel is operated by local gears F', F<2> to raise and lower the mandrel. Stops 6a, 7a engage lugs 6, 7 on the wheel E<1> to limit this movement, the gears F', F<2> being frictionally mounted on the spindles 12 to allow of slipping. The elevating and lowering gears are rotated in opposite directions by means of shafts 16 and gears 16<a> from the motor 20, mounted on the wheeled carriage A of the machine. Each set of local gears is resiliently mounted on a standard 15, a spring 21 being employed to press the gears into engagement with the wheel E<1>. An additional mandrel-turning device G may be mounted on a standard 27, the curved rack 26 of the device being carried by one arm 25 of a bell-crank lever, the other arm 25<b> being pressed by a spring 28, as shown in Fig. 13. A second device G may be mounted on the standard 27. The mandrel is elevated at the station S-1 and the metal introduced at S-2, a funnel L and blow-head H being employed. The mandrel is partially lowered by the device G and completely lowered at S-3, to meet a bubble-blower E, as shown in Fig. 8. The stem 32 is kept pressed against the conical seat in the mandrel E by a piston 34. Air is supplied by a pipe 30 and escapes from the hollow mandrel by holes 10<f>, finally passing into the mould by the passage 11<a>. After leaving the station S-3, the mandrels are inverted by the gears 9 engaging the bevel rack D, and are then opened for the bottles to be transferred to a blowing machine. The table B is rotated by means of the gear B<3>. The moulds may be retained in an upright position during their travel by means of a locking device or by frictional contact between the trunnions 1 and bearings 2. Specification 126,782 is referred to.

Title: Improvements in or relating to the treatment of organic refuse or the like material
IPC: B03B9/06
Filed: 1960-10-07
Abstract: 929,870. Compost fertilizer. COMPOST ENGINEERS Ltd., D. F. REES, S. A. GOTHARD, and L. P. BRUNT. Oct. 5, 1961 [Oct. 7, 1960], No. 34417/60. Class 111. Organic refuse e.g. dustbin refuse is aerobically fermented by continuously feeding the material into a first trough provided with means for moving the material therealong, continuously removing the partially fermented material at the other end of the trough on to a conveyer in such a manner that aeration is effected, returning substantially half the material into the first trough to be recirculated and passing the remainder to a second trough also provided with means for moving the material therealong. Partially fermented and unfermented refuse is thereby mixed in substantially equal proportions. Preferably the material after passing along the second trough is also continuously removed on to a conveyer, substantially half this material being returned to the second trough, the remainder forming the output of the process. Preferably the conveyers moving refuse to and from the troughs are smaller than, and move more quickly than the means for moving refuse within the troughs, which may be e.g. open-ended trucks or belt conveyers. In one embodiment, Fig. 1, a concrete tank 31 divided by central wall 32 into troughs 33 and 34 containing tracks 35 and 36 whereon run plate-like trucks 37. One end of the troughs are partially closed by plates 33a and 34a. Refuse 40, Fig. 2, is loaded on to truck 37 from belt conveyer 39. At the other end of the trough, the material is aerated by being lifted on bucket elevator 41 on to conveyer 42 which is provided with means, e.g. a deflecting plate for dividing the material, half to be returned via conveyer 44, Fig. 3, to the intake end of trough 33, the rest to be passed to trough 34. At the other end of 34, a deflection plate on conveyer 47 divided output from recycled material. The apparatus may also contain means for measuring and adjusting moisture and temperature, for removing unfermentable material e.g. glass and means for mixing other material e.g. sewage sludge with the refuse. The refuse may be recycled several times round the troughs to complete fermentation.

Title: Device for acoustic advertisements or the like
IPC: G09F25/00
Filed: 1935-12-12
Abstract: 453,087. Gramophones. CRONER, U., 109, Kurf³rstenstrasse, Berlin. Dec. 12, 1935, No. 34511. [Classes 40 (ii) and 118 (ii)] A gramophone carried by a motor vehicle is employed both as a device giving warning of approach and as an advertising or like medium. The table o carrying the record is rotated continuously by a motor e, a switch s being provided in the battery-motor circuit to stop the motor e when the vehicle is not in use. The stylus n, together with the soundbox m, is carried by a pivoted arm v on a lower extension u of which is an armature which can be attracted by an electromagnet b to insert the stylus in the record groove and cause sounds to issue from the horn. A spring f and a stop r control the movement of the arm v. The circuit through the magnet b is completed by depressing a key t to close a gap c in a byepass shunting the switch s in the battery-motor circuit. The switch s may act as an ignition switch, and would then be of the socket type which is withdrawn when the vehicle is stationary. The motor e would, when the switch s is taken out, not be excited and would start to rotate only when the gap c is closed. To mask the sound from the gramophone while the table o is speeding up, the horn is adapted to be sounded in the usual way by a circuit passing through a contact d and through the reed chamber g. The contact d has a part carried by a centrifugal governor q rotated by the motor e, and is broken when the table o attains the speed necessary for proper functioning of the gramophone. The table o may be of steel or other metal, and may carry the sound groove, which is preferably circular, either directly or on a flat ring mounted thereon. The table o may be driven from a moving part of the vehicle, and may be replaced by a drum, band, magnetic wire, &c. Means are provided for enabling the horn reed to be actuated at will.

Title: Improvements in or relating to centrifugal strainer separators
IPC: B04B3/02
Filed: 1955-12-02
Abstract: 808,376. Centrifugal strainer separators. BAKER PERKINS Ltd. Dec. 2, 1955 [Dec. 13, 1954], No. 34586/55. Class 46. In a centrifugal separating machine of the " pusher " type a casing 26 houses a basket 30 mounted on an end wall 28 keyed to a rotary shaft 14. The shaft 14 is hollow to accommodate a shaft 22 rotatable with it and supporting at one end a conical pusher plate 31 carrying a scraper ring 34 adapted to move over the basket 30 when the shaft 22 is reciprocated by a piston 20 working in a cylinder 18. The piston is actuated hydraulically in the forward or propelling direction of the scraper 34 under control of a control valve 78 and distribution valve 65; its return stroke results from accumulation of material on the basket 30. Mounted on the pusher plate 31 is frusto-conical distributer 35 recessed in its inner surface to accommodate filter screens 40, 41 of which the one 40, adjacent the distributer 35, is woven and the other is of mesh. The space between the screen 40 and the distributer 35 communicates through channels 43, 44 with the space between the pusher plate 31 and the basket wall 28 whence it passes to the easing 26 ; the easing is divided into compartments which separate this liquor and liquor from different parts of the basket 30 from one another. Slurry to be treated enters the distribution core 35 from an inlet pipe 39 and while the liquor drains away as above described, the solids move towards the base of the core 35 to traverse passages 37 between lugs which support the cone on the pusher plate 31 and accumulate on the inner surface of the basket 30, this accumulation pushing back the scraper 34 and pusher plate 31. The return may be slowed down by partially closing a valve in the return circuit from the valve 65. A nozzle 52a sprays wash water on the slurry on the screen 41 and a pipe 54 on to the material on the basket 30. As the solids pass from the basket 30 between a rim 46 thereon and a member 49 having a radial flange 49a and a frusto-conical one 51, the wetter and drier solids from adjacent the basket and more remote from it are intermixed. An electric motor drives, through a belt, a shaft 14a mounted on the cylinder 18 which is formed as an enlargement of the shaft 14.
