Title: Improvements in or relating to electric accumulator batteries
IPC: H01M4/64
Filed: 1947-10-14
Abstract: 643,087. Accumulators. GAZDA, H. O., and VIECELLI, L. Oct. 14, 1947, No. 27576. Convention date, Oct. 16, 1946. [Class 53] An accumulator plate comprises a conducting frame in which are supported a number of conducting carriers for the active material, the carriers being made of a material unaffected by the chemical reactions in the accumulator and the active material being in thin layers which are covered with a material permeable to ions, for example a film formed by dipping the plate in a film-forming solution. Fig. 3 shows a part of a plate comprising a frame 5 supporting carriers 6, 7.. Each carrier is made from a strip of aluminium or a lead-aluminium . or lead-antimony alloy which is covered with a thin foil of lead forming the active material which is covered with a film of regenerated cellulose. The strip may be folded in zig-zag as shown at 6 or rolled up as at 7 and the completed carriers may be connected to the frame by soldering. Two similar carriers may be inserted from opposite sides in the same opening, being soldered to metal sheets which extend across the central plane of the opening. Fig. 5 shows a modification in which fins 10 formed on a cast or extruded frame form the carriers. The fins are coated with lead electrolytically and are then covered with a film permeable to ions. ‹

Abstract: 604,391. Pneumatic despatch apparatus. LAMSON ENGINEERING CO., and HERRING, R. L. Oct. 22, 1945, No. 27747. [Class 78 (i)] Control apparatus for pneumatic despatch apparatus of the small coin type has a control chamber formed in two parts ; an upper part 6 containing a timing piston 11 and rod 12 and communicating at one end with the dispatch terminal at a point adjacent to the door or main valve 5 thereof and open at the other end 40 to the atmosphere ; and a lower part adapted to be attached to said upper part and comprising a dashpot cylinder 13 closed at the bottom and having an auxiliary piston 15 slidable therein to which the rod of the timing piston is attached, the rod of the timing piston carrying a plate or door 20 slidably mounted thereon and adapted to engage a seat on the upper cylindrical part of the chamber to seal it against the atmosphere when the main terminal valve is closed. Loose fitting piston 11, having air vents 23, and working in cylinder 6, carries on its rod 12, an abutment 22 which engages the slidable door 20 so as to lift it to close the lower end of cylinder 6. The piston rod slides through disc 9 which is attached by rods 10 to ring 8, the latter being detachably mounted by bayonet joint 25 to cylinder 6. The movement of piston 11 is controlled by plunger 15 working within dashpot 13 and by adjustable air inlet 19. Dashpot 13 is supported by a cage of rods 17. Mode of working. When door 5 is opened to insert a carrier, air is admitted, and piston 11 falls. When door 5 is shut and the carrier is despatched forward into the vacuum, the piston 11 remains in its position to allow air to flow both into the pneumatic tube until the carrier is discharged at the other end when the extra inrush of air past piston 11 pushes it up and door 20 rises to seal off the cylinder 6 from the atmosphere. Specification 455,346 is referred to.

Title: Wave filter
IPC: H03H9/00
Filed: 1939-10-13
Abstract: 533,171. Impedance networks. STANDARD TELEPHONES & CABLES, Ltd. Oct. 13, 1939, No. 27845. Convention date, Nov. 5, 1938. [Class 40 (iii)] In a band-pass lattice filter employing piezo-electric elements, instead of the series and diagonal branches Z<SP>1</SP>, Z2 having anti-resonance and resonance frequencies coinciding with the mid-band frequency f4, as indicated in Fig. 3, these critical frequencies f3,f5 are spaced slightly on either side of the mid-band frequency, as in Fig. 4. This produces a small hump in the attenuation curve and improves the distortion and cut-off properties of the filter, as well as increasing the available band-width. The attenuation at the mid-band frequency f4 is preferably made equal to that at the cut-off frequencies f2, f6. The shifting of the critical frequencies is obtained by having one pair of crystals slightly longer than the other pair, and by increasing the values of the shunt capacities. These capacities may be wholly or partly replaced by shunt capacities at the ends of the network.

[Class 103 (ii)] [Also in Group XX] In a light-polarizing device for use as a viewing analyzer for vehicles, one or more parts of an analyzing filter is movably mounted so that the direction of the transmitted vibrations from the filter, or from the effective part thereof, may be varied. The filter can thus be adapted to prevent dazzle both from polarized light from oncoming vehicles and, in fog, from the lamps of the vehicle itself. A single filter may be mounted in a suitably rotatable housing or a number of parts with different directions for the transmitted vibrations may together be slidably mounted to enable the required part to be brought into the field of view. The adjustment may be made directly by hand, or electrically or mechanically from a foot or steering-wheel control.

Abstract: 1,260,518. Knitting-machines. WIRKMASCHINENBAU KARL-MARX-STADT VEB. 3 June, 1969, No. 28078/69. Heading D1C. A device for transferring pre-fabricated goods from a storage bar 26 to each division of a straight-bar machine includes a transfer bar 7 transported to the needles by arms 9 which deposit it on a slide (4 Fig. 1 not shown) movable towards the needles. The loaded storage bar is movable on a carriage 19 across the machine and locked in position at each division. The arms 9 are locked in the receiving position shown by a pin 17 engaging a notch 15. Manual rotation of cam shaft 20 raises comb 28 between the points of the transfer bar so that the loops remain on the tips and lowers the storage bar. Fabric is then pulled onto the transfer bar. The arms 12 are lowered, so that the arms 9 whose ends engage the arcuate rack 11, are swung through 180‹. The fabric is thus deposited on the slide which is fixed to toothed racks (3) and thereby conveyed to the needles.

Abstract: 300,768. Orr, S. A., and Suenderhauf, O. L. Oct. 24, 1927. Operating and controlling gates electrically and pneumatically. - Power-operated gates at roadcrossings are controlled in conjunction with road and rail signals by. trains approaching the crossing from either side. A train passing the insulated rail sections 45, 46, 47 energizes in succession the relays 49, 50, 51, the armatures of which are interlocked so as to be held in operated position until the last wheels of the train clear the sections 47. Relays 49, 50 control signallamps 12, 13 and audible signal 11. Relay 51 controls the magnet 39 of the electromagnetic valve 42 which is energized to pass air under pressure from pipe 10 to the gate-operating cylinders 2, 2<a>, thereby causing the gates to descend to close the road-way, and to the trainstop operating cylinders 29, 29<a>, which remove a track-member from the path of a train-stopping valve arm on the train. Signal-lamp G<1> for indicating to the rail traffic that the road gates are closed is controlled by contacts 27 closed by the gates in their active position and a lamp R<1> for indicating that the track trip shoe 32 is moved clear of the train-carried apparatus is energized by closure of contacts 33 by an arm carried by the track trip device. To prevent closure of the gates whilst a road vehicle is across the rails, spring supported contact-making surfaces 18 are arranged between the rails so as to energize a relay 61 when a vehicle is across the tracks and thereby prevent operation of the valve 42. Fig. 2 shows the gates and the operating mechanism and the road traffic signals 11, 12, 13. The gate 5 slides with rollers in channel guides 4a on cylindrical posts 2, 2<a> in each of which moves a piston 3 connected to the gates by cables 6 and subjected to air pressure from the pipe 9. Spring- cushions 8 are fitted at the bottom of the cylinders. Barriers 14 obstruct the side walks when the gate is lowered.
