IPC: B65B69/00
Filed: 1951-03-08
Abstract: 705,391. Stripping blasting cartridges. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 31, 1951 [March 8, 1951], No. 5605/51. Class 9(1) Blasting cartridges are stripped of their wrappers by rotating the cartridges while applying gradually increasing pressure until the ends of the wrappers unfold and the outer edge of the wrappers become  free. Apparatus for unwrapping the blasting cartridges comprises a rotatable roller 1 on the surface of which are longitudinal ridges 2, the roller being spaced from a curved plate 3 having similar projections 4. The plate 3 is supported by arms 5 depending from a shaft 6 and a guard 7 is mounted on bearings 8. The position of the plate 3 is adjusted by means of a hand-wheel 9 rotation of which moves an adjusting pin 10 passing through the machine frame 12 to bear against the plate, which is held by a spring 13. Clearance between the plate and the roller is adjusted according to the diameter of the cartridges which are then fed into the apparatus through an opening 16, the cartridges being placed parallel to the roller 1. As the cartridges travel between the plate and the rotating roller the pressure on the cartridges progressively increases, so that when the cartridges fall from the plate on to the shoot 14 and into the tray 15 the ends of the wrappers are unfolded and partially unrolled.

Title: Improvements in electric calculating systems
IPC: G01F1/50
Filed: 1948-02-26
Abstract: 654,976. Control of A.C. motors. BAILEY METERS & CONTROLS, Ltd. Feb. 26, 1948, No. 5738. Convention date, Feb. 28, 1947. [Class 38(iii)] [Also in Group XXXVIII] A two-phase motor 38 drives a potentiometer arm 31 to balance a voltage E4 against a, voltage E3 proportional to the product of fluid flow and pressure in a pipe 1. The out-of-balance voltage E5= E3ŒE4 is amplified at 35 and fed in parallel to the grids of tetrodes 46, 47. The anodes of these tubes are fed in anti-phase through respective saturable core reactors 48, 49 and a transformer 50 from the same A.C. supply which produces the voltages E3, E4. Dependent on the phase sense of the out-ofbalance voltage one or other of the tubes 46, 47 conducts. If, e.g., tube 46 conducts, the impedance of the associated reactor 48 is reduced and both windings of the motor 38 are effectively energized therethrough from the transformer 50, the motor winding 55 being fed through the phase shifting condenser 58. When on the other hand tube 47 conducts, the impedance of reactor 49 is reduced and both windings of the motor are fed therethrough to reverse its direction of rotation.
Patent GB-992290-A (GB)
Title: Improvement in gas filtering apparatus
Inventor: WELLS ALFRED JOHN
IPC: B01D46/04
Filed: 1963-02-13
Abstract: The invention relates to gas filtering apparatus of the kind comprising a casing with inlets for dust-laden gas and an exhaust for filtered gas, and a filter assembly including a bank of bags arranged side by side in closely spaced relation, the bags including inserts to hold them open in use, and the dust being collected outside the bags.  Such an apparatus is characterized by the provision of nozzles arranged to direct compressed high energy gas into the spaces between the adjacent bags and thus on to their exteriors, i.e. the upstream faces of the filtering medium. The apparatus may be used, in addition to its normal filtering role, as a means for separating air from pneumatically conveyed powders, so as to exhaust the air and retain the powder in a silo or hopper.  The apparatus is designed particularly for dealing with fibrous dusts which tend to clog the spaces between the bags. The high velocity gas jets on the upstream side of the filter material induce reverse flow of filtered air from within the bags, which clears the pores of the filter material.  The apparatus is similar to that described in Specification 914,187, except that the nozzles are of course on the upstream side of the bags, and the bag structure is as described in Specification 905,113. The jets may be supplied with gas either individually through valves, or in groups from manifolds, each manifold being controlled by a valve.  The valves may be opened sequentially, or simultaneously periodically.

Title: Road traffic signal control system
IPC: G08G1/08
Filed: 1970-02-09
Abstract: 1,246,771. Road traffic signals. OMRON TATEISI ELECTRONICS CO. 9 Feb., 1970 [15 Feb., 1969], No. 6061/70. Heading G4Q. A system for controlling traffic at a junction of a minor road 2 with a major road 1 by means of traffic signals 20, 10, comprises sonic detectors 3a, 3b situated in the minor road at opposite sides of the junction. A controller 9 sequences the signals in a known manner and normally gives right-of-way to traffic on the major road; however, right-of-way is given to traffic in the minor road when this traffic comes within the detection zone A of the detectors 3a, 3b to produce a signal operating the controller. Traffic turning left or right from the major road 1 into the minor road 2 may also enter a zone A and thus cause the controller to give an unwanted right-of-way to the minor road. To prevent this occurring, the signal produced by a detector 3a or 3b by means of a vehicle within a zone A is only effective to operate the controller if the signal lasts for a predetermined time. Thus a vehicle which has halted in the minor road due to signals 20 being at red, produces a signal effective to operate the controller 9 whereas a vehicle turning from the major road into the minor road passes through a zone A in too short a time to operate the controller. As shown, the controller 9 produces a signal on a line 2R connected to AND gate 5 when the minor street signals 20 are at red and a signal on a line 2G connected to AND gate 6 when the signals 20 are at green. A timer 7 operates to transfer a signal from AND gate 5 to OR gate 8 only when the signal from detector 3a or 3b lasts for a predetermined time. This ensures that a signal D for operating the controller cannot be produced when the signals 10 are at green and vehicles from the major road are passing through the zones A. However, traffic halted in the minor road by the red signals 20 generates a signal D. If the signals 10 are red and signals 20 are green, the signals from detectors 3a, 3b pass directly from a gate 6 to the gate 8 to generate a further signal D and extend the green period on the minor road.

Title: Improvements in or relating to electrical apparatus for indicating the conditions inthe cylinders of internal combustion engines
IPC: G01L23/22
Filed: 1939-02-24
Abstract: 525,635. Determining physical qualities of materials. NAPIER & SON, Ltd., D., and RAMSAY, F. R. F. Feb. 24, 1939, No. 6144. [Class 37] Apparatus for indicating conditions in the cylinders of internal combustion engines comprises means for passing a current between the points of the sparking plug and measuring this current, without interfering with the normal working of the sparking plug. An auxiliary gap A, preferably of the quenched type, is connected in series with the lead to the sparking plug B from the magneto C. Across the sparking plug points is connected a circuit comprising a rectifier D, a high resistance E, a direct-current meter F, and a battery G. The rectifier D opposes the passage of the spark voltage through the meter circuit but allows current from the battery G to pass. A resistance H may be connected between the gap A and the sparking plug B to assist in quenching the spark and preventing high-frequency oscilla' tions. An electrolytic condenser may be connected in parallel with the meter F to provide additional damping and a variable shunt resistance may be employed to vary its scale. A diode or other rectifier may be connected in the lead from the ignition apparatus C instead of or in addition to the series spark gap A. A high resistance may be used in place of the valve, or a series condenser in place of the gap. The current through the meter F is an indication of the richness of the mixture, maximum current corresponding to the condition for maximum power. Heavy detonation causes a small rise of current. In a modification a high-frequency spark is employed and is prevented from passing through the meter circuit by a high resistance or high frequency choke. The spark may be produced by means of a series gap having one electrode connected to the ignition apparatus and the other electrode connected through a high frequency coil to earth and through a condenser to the sparking plug. In another modification the meter and battery are connected in series with the lead to the ignition apparatus, the circuit including a high-frequency choke and being shunted by a condenser or spark gap to filter the spark impulses.

Abstract: 418,957. Thermionic valve-holders. CINCH MANUFACTURING CORPORATION, 2335, West Van Buren Street, Chicago, U.S.A.- (Assignees of Knutson, C. L. ; 2335, West Van Buren Street, Chicago, U.S.A.) Feb. 28, 1934, No. 6496. Convention date, March 2, 1933. [Class 39 (i).] A socket assembly for thermionic valves and the like comprises a supporting structure having an aperture therethrough and a laminated socket structure having laterally extending attaching means engaging opposite sides of the supporting structure adjacent to the aperture, to secure the socket position in alignment with the aperture. Detent locking means may be provided to prevent accidental rotation of the socket. The socket shown comprises a top plate 1, Fig. 2, a bottom plate 2, a spacing washer 3 and a guide washer 4 secured by a rectangular rivet 5. The bottom plate carries a number of contact members 7 and has three notches 11 which engage corresponding projections 10 extending into a circular hole in the base-plate 8. The top plate has holes for the insertion of the valve pins, and carries three lugs 13 vertically above the notches 11 adapted to fit into notches 12 on the base-plate. In fixing, the bottom plate is inserted in the opening in the base 8 so that the projections 10 slip through the notches 11, as shown from below in Fig. 3. The socket is now rotated through an angle of 60‹, when the lugs 13 snap into the notches 12, as shown in Fig. 4. The socket is thus held axially by the pressure of the plate 1 on the base 8, and of the projections 10 on the bottom plate 2, and is locked against rotation by the lugs 13. The spacing member 3, Fig. 2, touches the projections 10 and prevents radial movement of the socket. In a modification for use with very thin base-plates, the projections 10 are bent downwards so as to space the plates 1, 2 rigidly apart. To prevent the projections 10 from slipping beneath the spacing member 3, additional bosses are made in the base-plate which engage the bottom plate 2 and prevent radial movement of the socket. The contact members consist of an oval tube 15 split to allow expansion and provided with a split flange 14 and a wiring terminal 17. Specification 421,961 is referred to.
