Abstract: 691,940. Rotary filters. TATTERSALL, F. MARSHALL, G. A., and SATTERLY, H. H. Oct. 15, 1951 [Oct. 17, 1950], No. 25298/50. Class 46 An outward flow rotary drum filter in which the unstrained liquid is fed to the interior of the drum through a tube arranged co-axially with the axis of rotation of the drum is provided with means for measuring the flow through the drum by the drop of pressure in the unstrained liquid as it enters the tube. As shown the drum 1 with cylindrical filtering surface 4 is closed at both ends by circular plates 3, 3<SP>1</SP> rotatable on bearings 6 supported on a tube 2 coaxial with the drum. The tube has an internal partition 11 forming two compartments, one, 9, serving for the discharge of debris washed into the troughs from the filter surface 4 by sprays 21, and the other, viz. 10 having circular openings 18 which serve for the supply of the unstrained liquid entering the tube through a bellmouth opening 14 from a chamber fed from a storage channel 16 through a sluice 17. A pipe 30 communicating with the chamber outside the bellmouth 14 records the pressure of water in the chamber before entering the tube 2 and a pipe 29 connected to compartment 10 of tube 2 records the pressure of the water after passing through the bellmouth.

Abstract: 1311609 Moulding food TAKASAGO PERFUMERY CO Ltd 19 April 1971 [31 March 1970] 25299/71 Heading B5A [Also in Division F2]  An apparatus for expanding thermoplastic food in a vacuum, e.g. chocolate or candy, comprises a mould 1 with a cover 4 sealed thereto by packing 3, and a valve 6 mounted on the cover to control a connection 5 to a source of vacuum. In operation, the food is placed in the mould, and a coupling 9 is placed over the connection 5. A connection 12 is then depressed within the coupling to cause a valve 6 therein to abut the valve 6 in the connection 5 and open a passage to vacuum. When the food has been expanded sufficiently, the coupling 9 is removed and the mould ispassed through a cooling tunnel. In Fig. 2, not shown, the valve takes the form of a rotary cock, and an inspection window (31) can be used to assess when the mould is full.

Title: Process for preparing allyl chloride and its monomethyl-substitution products
IPC: C07C17/156
Filed: 1965-06-16
Abstract: Allyl chloride and its monomethyl-substitution products are produced by a process wherein oxygen and either (a) a mixture of an olefin with 3 or 4 C atoms and HCl, or (b) a monochloroparaffin with 3 or 4 C atoms, or (c) a mixture of (a) and (b) is conducted over a catalyst containing elementary tellurium and/or a tellurium compound.

Abstract: 1,194,520. Milling. ESAB Ltd. 19 May, 1969 [21 May, 1968], No. 25470/69. Heading B3K. In a method of removing a welding bulge from a workpiece of circular cross-section, particularly a welded chain link 1, a rotating end mill 11 is displaced from an inoperative position (shown dotted) to an operative position and then caused to revolve about the axis of the workpiece to a final position 20. The cutter unit 8 which comprises a pneumatic motor, is pivotally mounted by pins 9 in a holder 7 and is normally urged by spring 12 against a stop 13 in the holder 7. The holder is mounted on a rotatable carrier 6 adapted to be rotated in either direction by a hydraulically operated rack 15 and gear 14 and an adjustable stop member 17 mounted on a support member 5 pivots the cutter to its inoperative, starting position at the end of an anticlockwise movement of the carrier 6. The method leaves a small remaining portion of weld bulge which may be removed by a punching operation but this may be omitted as the subsequent tumbling operation to which the chain is subjected can be relied on to remove it. In an alternative embodiment (Fig. 6, not shown) two cutter units are mounted on the rotatable carrier.

Title: Improvements in or relating to traffic control signals
IPC: G08G1/08
Filed: 1933-09-18
Abstract: 425,551. Road signals for controlling traffic. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, and TAYLOR, J. H., 28, Oxford Road, Waterloo, both in Liverpool. Sept. 18, 1933, No. 25770. Drawings to Specification. [Class 118 (ii)] In a road-pad operated traffic control system operated from D.C. mains, the lamps are controlled by electromagnetically - operated mercury contact switches and the control relays and cam shaft magnet are wound for a voltage lower than the mains voltage and are connected in series with resistances. The magnets controlling the mercury switches are operated directly from the cam shaft and, in operation, open circuits for the magnets controlling the corresponding lighting on the opposing road. A choke is connected in series with the lamp circuits to reduce the current flow when the lamps are switched on and condensers in parallel with the mercury switches absorb the inductive energy from the choke. The condensers controlling the timing circuits comprise blocks of condensers connected in parallel to enable various voltages to be easily catered for. The invention is described applied to a system having the usual vehicle extension and maximum timing facilities, and an additional maximum timing circuit is provided which becomes operative only in the event of faulty working of the system or a continuous fiow of traffic in a single direction, the circuit providing a pedestrian interval in this latter circumstance. Specifications 351,703 and 360,924 are referred to.

Abstract: 1,212,903. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. 21 May, 1969 [30 May, 1968], No. 25895/68. Heading H4K. Multiplex systems GE serve groups of subscribers' lines, each of which is allocated a fixed time slot in its system, the systems being connectible over co-ordinate matrix highway switching stages, such as A and B, to audio links AL which by demodulation and remodulation bridge differences between time slots used for originating and terminating paths in the exchange, a link system STL being provided for joining those originating and terminating paths that employ the same time slot as may occur when connecting subscribers with the same time slot from different multiplex systems, or as may be convenient in establishing incoming or outgoing connections. The link system STL provides amplification and is multiplexed to serve a number of connections simultaneously. The exchange is a p.b.x. and the A-stage gives access to satellite exchange links SL, tie lines TL, and exchange lines EL; each of these circuits having two appearances in the A-stage to permit use of a call-transfer facility FA. An operator's position MB has an appearance in the A-stage and also has access to that stage over a stage E. A register RG is accessible over stage D. To convert between multi-frequency keyset signals and other forms of signalling stores S are provided over non-t.d.m. switches L and M. While the use of link system STL allows the use of a single time slot when establishing a connection to or from an outside line, if no such slot is available, an audio link AL is employed.
