IPC: B62J6/00
Filed: 1969-07-23
Abstract: 1281015 Warning lamps for bicycles; battery lamps P H MAC MAHON 23 July 1969 [29 Oct 1968] 36975/69 Heading F4R A warning lamp adapted to be attached to the outer end of a bicycle pedal comprises a translucent box-like housing 26 which has an opening 70 in each end wall 28, 30 and contains a pair of batteries 52, a gravity-actuated switch 46, and a pair of bulb socket shells 62 holding bulbs 68 which project partially through the openings. The socket shells are electrically connected by brackets 56 to respective terminals 60 of the batteries and are secured to a U-shaped connector 66 by means of centre contacts (not shown), insulating spacers 64 being provided. The assembly consisting of the connector 66, the brackets 56, the shells 62 and the bulbs 68 is held in the housing by the engagement of the bulbs with the openings 70, the connector 66 being sufficiently resilient to permit the bulbs to be moved towards one another to disengage the assembly from the housing when required. The switch 46 comprises an arm pivoted on one of a pair of posts 40 which are secured to the housing and are electrically connected to the adjacent terminals of the batteries and to each other. When the arm is at the lower side of the housing it rests clear of the connector 66 but if the pedal is rotated through 180 degrees to bring the arm to the upper side it then rests on the connector and completes the circuit to the bulbs. The outer end of the crank-pin (10) of the pedal may carry cam projections 75 so that as the pedals rotate the switch arm is periodically lifted clear of the connector 66 to flash the bulbs.

Title: Improvements in apparatus for drying grain
Inventor: SMALL WILLIAM CHARLES
IPC: F26B17/12
Filed: 1959-11-04
Abstract: 895,707. Drying grain. KENNEDY & KEMPE Ltd. Nov. 4, 1960 [Nov. 4, 1959], No. 37379/59. Class 34(2) In a grain drying apparatus, the grain is dried while falling down a number of vertical columns through which drying air is passed transversely, the columns being inside an outer casing and the wet grain being distributed at the top of the columns and the dry grain being collected at the bottom of the columns by respective conveyers. The drier comprises an outer casing 10, Fig. 1, housing vertical columns, Fig. 3, through which the grain falls by gravity and through which drying and cooling air is transversely passed from trunking 22, 25 respectively into air spaces formed between the columns at one side of the casing, which spaces alternate with exhaust spaces connected at the other side of the casing to a single exhaust 26. The columns comprise louvre plates 13 extending from side to side of the casing, the vertical portions 14 of which being spaced apart by gaps 16 through which the drying air enters at one face of the column and passes via a route through the grain therein made devious by inclined portions 15 of the louvres through the gaps on the opposite face of the column for exhaustion through the exhaust spaces. The air spaces are divided horizontally into sets separated by plates 17 and flanges 18, formed of inclined extensions of the vertical portions 14 of the louvre plates. The grain is raised by an elevator 12 having a wide discharge mouth for spreading the grain across a horizontal plate 28 from which the grain is removed by the upper run of a slat conveyer to a lower plate 31 having transverse slots above the open upper ends of the columns, through which the grain is distributed by the lower run of the conveyer. The dried and cabled grain is collected on a horizontal plate 33 which is so divided that each adjacent pair of columns delivers on to a separate portion from which it is swept by a further slat conveyer on to a lower plate 35.

Abstract: 1,016,884. Aerating and agitating liquids. AMERICAN MACHINE & FOUNDRY CO. Oct. 4, 1962 [Jan. 25, 1962], No. 37588/62. Heading B1C. [Also in Division A2] In the preparation of carbonated frozen desserts e.g. soft ice-cream or frozen custard, frosty milk shakes and malted drinks, streams of liquid confection mix and carbon dioxide gas are admixed at essentially atmospheric pressure under substantially non-turbulent mixing conditions before subjecting the mixture to a beating and chilling step, and the mixture obtained is then beaten and chilled. Carbon dioxide gas from a cylinder 10, Fig. 2, is commingled with liquid dessert in a zone 8 before these pass into a freezing chamber 26 furnished with a beater 30 powdered by motor 46. The chamber incorporates a gate or door 31 for cleaning and servicing, and a draw-off assembly 32 actuated by a handle 33. The liquid flow control element 48 enables the flow of liquid dessert mix through the conduit 25 into the zone 8 to be independent of the liquid level 24. That part of the liquid mix feed assembly 21 holding the concentric tube 23 is sealed off at the top 19, thus creating a gas reservoir for developing sufficient back pressure to ensure incorporation of the gas into the liquid mix and to maintain a uniform self-adjusting flow of carbon dioxide gas into the freezing chamber 26. The flow of gas is synchronized with the operation of the beater by a solenoid valve 28.

Title: Hydraulic follow-up valve for servo-assisted steering gear or the like
IPC: B62D5/09
Filed: 1973-08-08
Abstract: 1379200 Power assisted steering mechanism V LANGEN [trading as LANGEN & CO] 8 Aug 1973 [26 Aug 1972] 37605/73 Heading B7H [Also in Division G3] An hydraulic follow-up valve system, e.g. for servo-assisted steering gear, comprises two control valves 50, 51 operated by a common actuator 60 for alternatively establishing communication between servomotor chambers 58, 59 and a pressure source 13 or return lines 11, 44. Valves 50, 51 are formed by pistons 48, 49 slidably mounted in bores 46, 47 in a rotatable body 45 connected by mechanical feedback linkage to movable cylinder 55 of servomotor 54, the latter having a fixed piston 57. The actuator 60 contains adjusters 61, 62 for the setting of control springs 65, 66 which force respective tappets 69 against valve pistons 48, 49, The latter have ducts 71, 72 which communicate the pressures within respective servomotor chambers 58, 59 to reaction chambers 73, 74 in opposition to the forces of springs 65, 66. If actuator 60 is turned, say, in a clockwise direction, e.g. by a steering wheel, the compression of springs 65, 66 will respectively increase and decrease causing pistons 48, 49 to move upwardly and downwardly respectively. Consequently the pressure in chambers 58, 73 will rise whereas that in chambers 59, 74 will fall, thus causing cylinder 55 to shift to the left until the feedback linkage has rotated valve body 45 into a position in which pistons 48, 49 return to the neutral state. In a modification (Fig. 1, not shown) the actuator (20) is a piston slidably disposed in a valve body (40) and acting at its opposite ends on control springs (19, 36) respectively engaging landed valve pistons (3, 22) slidable within the body. Reaction chambers (18, 35) are provided at the other ends of the valve pistons and are in communication with the respective chambers (43, 42) of the servomotor (16). The cylinder (37) of the latter is fixed and the piston (38) movable and connected by a feedback link (41) to the control valve body (40) to provide a moving seat followup. An additional elastic feedback means may be provided. The control springs (19, 36) or 65, 66 may be of coil or leaf type. Several servomotors may be connected in parallel.

Title: Metallic Path Acoustical Seismic Source
IPC: G01V1/157
Filed: 1967-08-17
Abstract: 1,156,579. Generating seismic energy. TELEDYNE INDUSTRIES Inc. 17 Aug., 1967 [19 Oct., 1966], No. 37864/67. Heading H4D. In an arrangement for generating acoustical inpulses under water (e.g. for seismic surveying) by electrically " exploding " a wire bridging spaced underwater contacts the wire is supplied to the contacts via tubular means in which it is entrained in a flowing fluid. Thus the wire 18 (Fig. 2) carried by reel 16 is conveyed to a first electrode 12 via tubular means 20 in which it is entrained in a flow of water produced by a pump 32. Electrode 12 is provided with a bore 12a (Fig. 3) through which the wire is carried towards the second electrode 14 by the water flow the latter electrode being streamlined so that the flow causes the wire to " hug " its surface. The electrode structure (Fig. 3) is towed behind a vessel V (Fig. 1) by a cable C comprising the tubular means 20 and the electrical conductors 22, 24 which connect the electrodes to an electrical energy source 20 via trigger operated switch means 10. In operation a timer controller K releases brake 42 to allow a length of wire sufficient to bridge the contacts to be carried into the required position by the water flow, pump 32 being continuously driven by (internal combustion engine) motor 34. The brake then arrests reel 16 and causes trigger T to close contacts 10 so that the resulting " explosion " (vaporization) of the wire by the flow of current from source S produces a (steam) bubble the size and rate of change of which determine the energy of the resulting acoustical impulse.

Title: Method and apparatus for bending and annealing glass sheets
Inventor: LEFLET HERBERT ARCHIE
IPC: C03B23/025
Filed: 1966-08-24
Abstract: 1,132,790. Bending and annealing glass sheets. LIBBY-OWENS-FORD GLASS CO. 24 Aug., 1966, No. 37870/66. Heading C1M. In a method for bending and annealing glass sheets on a skeleton mould to produce a preselected stress pattern in the glass sheets, heating means applied directly to the shaping rail is operable to heat preselected areas of the sheet during engagement of the bent sheet with the shaping surface. A mould 11 comprises a relatively narrow continuous shaping rail 14, arranged in a closed configuration conforming in outline to the glass sheets and braced by rods 15 extending across the mould. The shaping rail is supported by posts 17 upstanding from a rack 12 and guide rails 20 are secured to the underside of the rack to guide the latter for movement over a roller type conveyer 21 through a tunnel furnace. One shaping rail is electrically heated, with power supplied by busbars 24 which extend through the desired zones of the furnace, the power being conducted to the shaping rail by coupling means 25. Electrical heating elements 26 of the resistance type are mounted on the shaping rail and connected by flexible conductors 27 to the two coupling means 25. Each coupling means 25 comprises a wheel 30 having an outwardly opening groove 31 in its outer periphery which groove receives the bus-bar (24). The wheel is journalled on one arm of a bifurcated arm 32 having its opposite end pivoted on a pin 33 received in a clevis bracket 34 secured as by bolts 35 below the mould, to the leading side rail 18 of the rack. The arm 32 projects backwardly towards the trailing side of the rack and is adapted to swing up and down about the pin 33 as an axis permitting the wheel to swing toward or away from the underside of the mould. Preferably supplementary heating begins when the mould is in or closely adjacent to the bending zone of the furnace, and is discontinued at the point within the annealing zone of the furnace whereat the remainder of the sheet has cooled to a temperature below 900 F. Supplementary heating of the shaping rail produces areas of tension and compression in the sheet so that the peripheral edge of the cut bent sheet is in compression and therefore stronger. Other means of supplementary heating include directing flames on to the shaping rail or passing hot fluid through a conduit attached thereto.

In a plasma generator, a direct current arc is sustained between first and second electrodes 3, 4, Fig. 1, and the plasma formed thereby is directed by gas jet 5, through the hollow second electrode into contact with a third electrode 6, an alternating current arc being created between electrode 6 and an electrode other than the first electrode. As shown, an alternating current source is connected between electrodes 4 and 6, electrode 6 being the workpiece. Cooling fluid is circulated through chamber 10 in hollow electrode 4, and may be ejected into the plasma within, or immediately below, electrode 4, Figs. 13 and 14 (not shown). Electrodes 3 and 4 may be mounted together on a frame and moved further away from electrode 6 after formation of the plasma. Two or three hollow electrodes may be provided between the first electrode 3 and the workpiece, the alternating current arc being formed between the two, or the last two, hollow electrodes, gas jets 5 being provided in front of each. Two or more assemblies of first and second electrodes 3, 4 may be provided, each hollow electrode 4 being connected to one of the phases of a multi-phase source 25, Fig. 6 (not shown), and the plasma jets from the assemblies being convergent. Alternatively, one assembly may be replaced by a workpiece, connected to the remaining phase of source 25, and on which the plasma jets are convergent. In a further arrangement, Fig. 9 (not shown), the plasma from electrodes 3, 4 is directed on to the ends of inwardly-moving wires 34, 35 &c., each of which is connected to one phase of a multiphase source 38. Known circuits are described for preventing mutual interference between the direct and alternating current circuits.

Abstract: 876,218. Indicating-apparatus; barometric gauges. BENDIX CORPORATION. Nov. 9, 1959 [Nov. 26, 1958], No. 37921/59. Classes 106 (2) and 106 (4). [Also in Group XIII] In indicating-apparatus with an elongated bimetal element 50 in its motion-transmitting mechanism to compensate for dimensional and/or elasticity changes with temperature, the element 50 is rotatably mounted in a coupling member 40, which is rotatably secured to a lever 36 projecting from a driven rock-shaft 20, and has an eccentric aperture, in which the element 50 fits, slidably and rotatably. In an altimeter, expansion and contraction of a capsule 24 in response to changes in ambient pressure cause rotation of a pointer 12 through a link 60, pivoted to the capsule 24 and to the bimetal element 50 which is eccentrically mounted a press fit in a member 40, itself rotatable in a crank arm 36 secured to a rockshaft 20, driving the pointer 12 through sector gear 18. The effect of the bimetal element 50 can be adjusted by moving it in or out of the member 40 to change its effective length and by turning it about its axis T to orient its bending plane. The component of the displacement of the element 50 radial to the crank 36 affects the transmission ratio while the tangential component affects the zero position of the pointer. When the element has been adjusted to give the correct response to temperature variation, the instrument is calibrated by turning the member 40 to readjust the transmission ratio and zero is adjusted by turning the scale 10. The sector gear 18 and crank arm 36 are held on the rock-shaft 20 by set-screws and the capsule 24 is adjustable relative to the instrument case by means 30, 70. Alternatively, the transmission ratio adjusting member 40 could be inserted in the motion-transmitting mechanism between the crank arm 36 and rock-shaft 20 or between the bimetal element 50 and link 60. " Invar " (Registered Trade Mark) and copper may be used for the element 50.

Abstract: 1,151,028. Injecting pastes into high-pressure filters. POLYSIUS G.m.b.H. 18 Aug., 1967 [30 Sept., 1966], No. 38200/67. Heading B1D. Paste is injected into a high pressure filter press 6 by first injecting it by means of a high pressure pump 2 into a reservoir 3 filled with fluid under pressure, and then allowing this pressure to drive the paste into filter 6. As described, a medium pressure compressor 12 feeds air to a high pressure compressor 14 and also to storage tanks 13. Compressor 14 charges buffer reservoirs 4 and hence reservoir 3 to high pressure. Next, paste from storage reservoir 1 is forced into a reservoir 3 by pump 2, while a low pressure pump 5 fills filter 6 with paste. Owing to the large size of reservoirs 3, 4 and also to an automatic discharge valve 15 shunting compressor 14, injection of paste into reservoir 3 does not significantly increase the pressure therein. Valves 7, 8 are then closed and valve 9 opened, letting paste be forced into filter 6. After filtration, valve 10 is opened to allow compressed air in reservoirs 13 to flush out the liquid in filter 6 through valve 11.
