Title: Tungsten filament mount and a method of making
Inventor: GEORGE FREDERICK J
IPC: H01K3/02
Filed: 1969-12-03
Abstract: 1,254,616. Tungsten filament assembly. SYLVANIA ELECTRIC PRODUCTS Inc. 3 Dec., 1969 [3 Dec., 1968], No. 59039/69. Heading H1F. A filament assembly for a quartz halogen lamp bulb comprises a stabilized coiled-coil tungsten filament 1 from which extend at either end, perpendicularly to the axis of the coiled coil, coiled legs 2, each coiled leg having a tungsten support wire 4 inserted in good electrical contact therein for substantially the whole length of the leg to short out the coils of the leg to prevent ineffective incandescence, the support wires having preformed bends in those parts within the legs to shape the legs to reduce the spacing between them and thus allow a smaller press seal to be used in the bulb. The coiled legs are crimped on to their support wires. A length of molybdenum ribbon is welded to the free end of each support wire and the filament mount is press sealed in a quartz envelope. During fabrication of the filament it has a fibrous microstructure which permits cold working, but after insertion of the support wires it is stabilized in a jig. All dimensions of the filament assembly are given.

Abstract: 1,161,464. Seats. STEWART-WARNER CORP. 29 Dec., 1967 [30 Dec., 1966], No. 59130/67. Headings A4J and A4U. In a tilting chair, a back-rest rotates about the axis of a torsion bar 38, which opposes its rearward pivoting motion, while a seat participates in this motion to a reduced extent, by turning about its front pivotal connections 90, by which it is mounted on a stationary support body 22. The ends of bar 38 are secured in extensions 32, 34 of the support body, which has integral side walls 24, 26. The backrest, which is adjustably clamped in angularly adjustable shoe 64, turns plates 44 about bearings 42, carried on bar 38 and applies a moment to the bar 38, by means of screw 50 engaging arm 48, fast with the bar. The rotation of plates 44 is transmitted to the rear of the seat by toggle linkage 56 connected to seat fastenings 84. In another form, pivots 90 are replaced by a torsion bar (100, Figs. 8 and 9, not shown).
Patent GB-1433797-A (GB)
Title: Skid control system for a vehilce braking system
IPC: B60T8/1764
Filed: 1973-12-21
Abstract: 1433797 Antiskid braking systems KELSEY-HAYES CO 21 Dec 1973 [10 Jan 1973] 59388/73 Heading F2F An antiskid braking system comprises an electronic circuit for generating a repetitive reference signal, including means for causing the repetition rate of the reference signal to represent a speed substantially corresponding to the speed of the vehicle so long as the deceleration rate of a selected wheel does not exceed a predetermined value, and for causing the said repetition rate to change in a predetermined fashion when the deceleration of the selected wheel exceeds the predetermined value. The skid control circuit 18 includes a logic circuit 20 which selects a wheel, a rate limited phase locked loop circuit 22, frequency divider circuits 24, 26, a frequency comparator circuit 28, a lowspeed cutout circuit 30 and a gate circuit 32 and a conventional brake pressure modulator 33 is controlled. Digital signals W 1 , W 2  derived from wheel speed sensors 35, 37 are fed to circuit 20 which compares the signals and causes the signal having a higher frequency to be duplicated at terminal 20c and the lower frequency signal similarly duplicated at terminal 20d, so that the signal representing the speed of the faster wheel is supplied to input 22a of circuit 22 and the slower speed signal to input 28a of circuit 28. The circuits 22, 24 co-operate to develop a digital signal at output 22b whose frequency is equal to a predetermined multiple of the frequency of the faster wheel signal as long as the rate of change of frequency thereof does not exceed predetermined limits, i.e. the phase of the signal at input 22c is locked to the phase of the signal at 22a. Circuit 22 is constructed to limit the rate at which the frequency of the signal at output 22b can decrease and this output is also frequency divided by circuit 26 so that the signal at output 26b represents a proportion of the speed of the fastest running wheel and forms the vehicle velocity reference signal V r . Circuit 28 compares the frequencies of the signals at inputs 28a, 28b and produces an output at 28c when the signal at 28a is less than that at 28b and causes brake pressure to be relieved providing that the vehicle speed is greater than a predetermined minimum as established by circuit 30. In a modification Fig. 3 the circuit 78 also includes an up-down logic circuit 80, a 64 bit shift register circuit 82, an additional frequency comparator circuit 128, a frequency adder circuit 84, a gating circuit 132, a frequency standard circuit 86, a fail safe circuit 88 and an amplifier circuit 90. Circuit 86 generates five digital signals, an up-rate signal, a down-rate signal, a low speed signal, a slip frequency signal and a clock signal, the operation being such that the frequency of the signal at output 82c represents the speed of the faster running wheel multiplied by sixty-four minus the speed represented by the slip frequency which is constant in this circuit.

Title: Device for releasing individual coins of a coin store
IPC: G07F5/20
Filed: 1968-12-13
Abstract: 1,242,075. Selective coin release mechanism. KIENZLE APPARATE G.m.b.H. 13 Dec., 1968 [27 Dec., 1967], No. 59438/68. Heading G4V. A coin store with means for selectively releasing individual coins, in which different denominations of coins are kept in different channels, the channels being parallel and inclined in the direction of motion of the coins, empties the coin channels one after the other in a sequence depending on the size of the coins contained therein, the release being effected by the movement of a control member to operate a tripping member covering the coin channels, said tripping member having several releasing tongues of different lengths, are being assigned to each coin channel, which act one after the other on laterally movable coin locking see-saws, one in each channel, to release the coins therefrom. The channels 1, 2, 3 are formed between vertical plates 4-5, 6-7, 8-9 closed at the bottom by adjustable rails 11 and rails 10. A selector 17 rests on the open top of the inclined channel against lugs 14 and 15 on the sides 4 and 9 under the action of a spring 18 or its own weight. Projections 22, 23, 24 extend downwards from the selector into the coin channels and can engage pivoted see-saw members 25, 26, 27, which are pressed by springs 45, 46, 47 against the outside wall of each channel. Long noses 33, 34, 35 and shorter noses 36, 37, 38 project into the coin channels via slots cut in the walls. The projections 22, 23, 24 are of different lengths and correspond to different coins to be used in the device. When a large coin enters shoot 1 it rolls until stopped by long nose 33 of see-saw 25, and in this position bears on part 31 of the selector 17, raising it to such a height that projection 22 can bear on see-saw 25, but the shorter projections 23 and 24 are too high to bear on see-saws 26 and 27 whereby their long noses 34, 35 block the lower ends of the respective channels 2 and 3. Operation of lever 29 moves the selector transversely across the shoots and causes the long nose of see-saw 25 to be pushed out of shoot 1, thereby releasing the lowermost coin. At the same time the short nose 36 of the see-saw enters through the slot 4<SP>11</SP> into shoot 1 and pinches the second to lowest coin against the shoot, thus preventing more than one coin being released until the operation is repeated. When all the largest coins have been dispensed, the same mechanism operates with channel 2 via projection 23 and see-saw 26. If any coins are left after selection they may be returned from the shoots by moving rails 11 to allow them to fall out of the coin store. Rails 11 may be adjusted to accommodate coins of varying diameter so that they may be discharged in the order of descending value. The apparatus is suited to deliver single coins to a credit store for goods dispensed in discretionary quantities (e.g. petrol), the coins of highest value being used first and the coins of lowest value being used last or returned if the quantity of goods required has been delivered prior to using all the coins.

Title: Process and apparatus for removing volatile components of materials
IPC: B29C48/82
Filed: 1973-12-22
Abstract: 1431978 Evaporating solvent from plastics WELDING ENGS INC 22 Dec 1973 59703/73 Heading BIB [Also in Divisions B4 and B5] A volatile component is removed from a plastics material in a screw extruder, by a gas which is injected into the material in a zone of the extruder to flow in the opposite direction to that in which the material is being delivered by the extruder screw. The gas is injected at 28 at a location in the zone 27 at which the material fully fills the screw flight and is at a pressure which is lower than that of the gas and of the material downstream thereof, but is higher than at an upstream location 34 at which the gas and volatile component are vented. The described apparatus comprises a non-intermeshing twin-screw extruder heated by a jacket 16 and which, upstream of the zone 27 comprises a zone, or more than one zone, separated by cylindrical or reverse pitch screw segments, in which vapour is removed e.g. at above atmospheric pressure, by a vent 20 adjacent a reduced diameter shaft section 22 of the screws. The zone 27 is defined between pressure sealing cylindrical, or reverse thread, screw segments 24, 26, and a lower pressure of material adjacent vent 34 is maintained by a reduced diameter screw shaft with the higher pressure adjacent location 28 being maintained by the segment 26 and a decreased screw pitch ensuring that the screw is filled. The gas and component are removed at atmospheric pressure, or under vacuum at 34, with intermeshing twin screws 30, 32 being provided to return any escaping plastics material. Downstream of zone 27, water may be injected to effect cooling of the plastics, being removed as vapour under reduced pressure at 38 together with some of the gas injected at 28. The plastics may comprise polystyrene, polypropylene and polycarbonates, but the examples relate to polyethylene from which hexane or a mixed hexane-cyclohexane solvent volatile component is removed by steam.
