Title: Apparatus for detecting foreign metallic bodies in pneumatic vehicle tyres
IPC: G01V3/15
Filed: 1960-06-16
Abstract: 895,089. Locating conductive bodies. ROSSNER, H., and BERANEK, J. June 16, 1960 [June 18, 1959], No. 21169/60. Class 37. In an arrangement for detecting foreign metallic bodies in pneumatic tyres, the change of inductance of a search coil 10, Fig. 1, resulting from the presence of such a body within the field of the coil is used to produce an indication. The coil is embedded in an insulating material and is U-shaped as in 17, 18, 21 to embrace the tread of a tyre 19 which is mounted to be rotated for search purposes. Different sizes of plug in coils may be provided for different tyre widths and the coil may be adjustable as by swivelling or bending relative to the housing. Coil 10 forms a part of a tuned circuit A, Fig. 5, in an oscillator comprising the left-hand side of double triode 20, the generated frequency of the oscillator being compared in a pentode 40 with the output from an oscillator comprising the right-hand triode and tuned circuit B 57-59 to provide a control voltage for an indicator tube 44 which actuates a light indicator in housing 11. Capacitors C46, C48 suppress the high frequency, and capacitor C34 permits adjustment to frequency correspondence in the absence of a foreign body.

Patent GB-628926-A (GB)
Title: Improvements in or relating to reversible rotary vane type fluid motors
IPC: F16H61/40
Filed: 1947-08-06
Abstract: 628,926. Rotary engines and pumps. MANLY CORPORATION. Aug. 6, 1947, No. 21379. Convention date, May 24, 1940. [Class 110(ii)] The engine or pump is of the type described in Specification 627,924 with different pressures acting on the undersides of the outwardly-sliding vanes while they are passing over the inlet and outlet ports, and the sealing arcs between, has valve means to ensure the correct fluid flows to the various ports and passages when the rotor is reversed. Fig. 8 shows one arrangement in which fluid under pressure is supplied to engine inlets 37 and exhausted from outlets 36 and fluid is also supplied to under-vane ports 46 ... 49 at differing pressures. Fluid under pressure enters from a pipe 39 and divider, one stream being controlled by a valve 88 (see Specification 627,924) and being led to ports 37, with a control valve 103 positioned as shown. Fluid exhausted from ports 36 passes back to source by way of pipes 42, 38 . The other part of the stream from 39 flows up a pipe 45 and is directed to under vane ports by an automatic valve 72 controlled by fluid going to or from ports 36, 37. The ends of the valve 72 may have dash-pots instead of springs. The Figures 9 and 10 show arrangements to secure quiet running and means for catering with inertia loads when the motor, on reversal of flow of fluid, temporarily acts as a pump. The floating valve 170 has a supply 45 feeding into a wide inlet 164, wider than a piston 172 on the valve and hence the fluid supply may pass to both chambers 165,166 when the piston is in mid-position. Fluid is supplied by a pump 190 and passes through one of the check valves' 195 or 196 when its pressure exceeds that in the corresponding end of the floating-valve bore. The pressure in pipe 192 is maintained constant by a relief valve 197. The auxiliary force from pump 190 has a pressure greater than that of the fluid in pipe 42, and passes through check valve 195 into bore 177 to the vane slots 46 to hold the vanes outwards during the time the rotor is " over-running" on reversal. The pressure required to open a relief valve 184 is preferably slightly higher than that in the bore 177. After reversal of the rotor, the vanes discharge fluid into slots 46 and build up pressure in the bore 177 to close the check valve 195 and open the check valve 184. Fig. 10 shows a further arrangement in which pressure fluid in the pipe 43 is supplied to a pair of ports 37 and, by way of a check valve 206, to a bore 204 to force a valve 201 to the right and supply high pressure fluid from a source 45 to undervane ports 47. A valve piston too is moved independently of the piston 201 to control the fluid flow to and from a pair of undervane slots 46. On reversal of flow in the circuit, the pressure in pipe 42 and bore 220 drops, and piston 200 is pressed to the right by a spring 225. Pressure fluid then passes into the end 220 via bores 233, 234 and restores the piston 200 to the left during the " over-run of the rotor on reversal.

Title: Ballast Operated Filter
IPC: E04H4/12
Filed: 1968-05-06
Abstract: 1,190,886. Swimming baths. FILTRATION EQUIPMENT CORP. 6 May, 1968 [5 May, 1967], No. 21382/68. Heading A4N. [Also in Division B1] A gravity-flow floating filter 10 is backwashed by causing it to sink in the pool of filtrate 11 in which it floats. As described with reference to a floating swimming-pool 13, a pump 45 forces dirty water from a main body e.g. a river 12 into a gullet 28 surrounding a "rapid sand" filter 10a of the cellular type disclosed in U.S.A. Specification 3,080,062. The liquid level L 1  is maintained by controlling pump 45 by a float-operated switch 47. Filtrate leaves through the filter base and enters the pool, whose level L 2  is maintained by scuppers 16. A pontoon 20 causes the filter body 10 to float. To cleanse the filter a bleed valve (42) (Fig. 1, not shown) in line 38 is opened, allowing supernatant air to escape from pontoon 20 so that the latter sinks, Fig. 3 (not shown), causing backwashing of the filter by rising filtrate. Dirty backwash is discharged through line 52. A platform 17 extends inwardly of the pool around its entire periphery.

Title: Improvements in processes for the treatment of yarns and textile fibres and machines therefor
IPC: D06B3/02
Filed: 1922-08-05
Abstract: 206,250. McIntosh, D., and McIntosh, G. Aug. 5, 1922. Materials supported on endless conveyers.-For treatment with liquids, yarns and masses of fibres, such as wool, are supported between a pair of carrier bands or tapes 1, 2 passing over a plurality of single rollers 3, 4 immersed in liquid; by arranging these rollers so that the adjacent sections of the bands form obtuse angles one with the other, or by the use of tapes instead of a band the desired light pressure treatment of the materials when passing over the rollers is obtained. A pair of squeezing-rollere 6 may be placed at the entry of the vat, and another pair 7 at the discharge end; to prevent lapping of the fibre round the latter of these squeezing rollers, the lower band 2 is extended by rollers 8 so as to obviate an acute angle in the bond. The lower band is then brought back through the vat in order to agitate the liquor. The rollers 3, 4 are supported inside the vat by plain socket bushes 11 at one side and at the other by open bushes 12 closed by pins 13.

Title: Improvements in or relating to sheet feeding apparatus
IPC: B41F33/00
Filed: 1960-06-22
Abstract: 913,722. Feeding sheets. GOLDING, W. F. June 12, 1961 [June 22, 1960], No. 21876/60. Class 100 (1). In an electrical circuit means for indicating the absence of a sheet correctly registered against front lays in a sheet-feeding apparatus, means is provided whereby the apparatus will still operate when no sheets are being fed, or when there is no sheet within a distance from the lays equivalent to the length of a sheet. As described, the invention is applied to apparatus for feeding sheets 11 over a pivotable table 10 provided with fixed front lays 14, from where each sheet is taken by grippers 15 on intermittently-driven chains into a platen press. When the sheet is registered correctly, the table 10 and lays 14 are swung downwardly to enable the grippers 15 to feed the sheet. An arm 19, which is pivoted at 20, is lowered by a link 21 at each sheet-feeding operation to the position shown, and has resiliently-mounted therein two plungers 25, 37 with adjusting nuts. The plunger 25 has a base contact 17 which cooperates with a contact 18 secured to the table 10 and provided with an edge 24 adjacent the lays 14. A finger 34, pivoted at 35 to the plunger 25, extends past the plunger 37 and overlies a recess 43 in the table 10. An electric circuit 44 is established to stop the apparatus only when a sheet 11 covers the recess 43 on the table 10 but is not in register with the lays 14, thus enabling the circuit to be completed through the mating contacts 17, 18, the plunger 25, arm 34, and plunger 37. If there is no sheet present, or a sheet is not sufficiently advanced to cover the recess 43, or no sheet has been fed, the circuit is not completed, since the arm 34 drops into the recess 43 away from the plunger 37. The press, which drives the sheet-feeder, is driven through known electromagnetic clutch and brake mechanism operated by a relay 45 in the circuit 44, and when the circuit 44 is established the clutch is disengaged and the brake applied to stop the press instantly.
