Title: Deflation detector for pneumatic tyres
IPC: B60C23/04
Filed: 1947-08-12
Abstract: 634,874. Pneumatic tyres. SPANGLER, F. Aug. 12, 1947, No. 22389. [Class 144 (i)] An electrically-operated tyre-deflation indicator comprises a piston 2 loaded, by a spring 7, against the pressure in the air-tube 5 of the tyre and fitted in a metal sleeve 1 secured to the wheel-rim 3 which forms one terminal of the operating-circuit, the piston-rod 10 being insulated from the other terminal 15 of the circuit, the circuit being automatically closed, on tyre-deflation, by the lift of an adjustable nut 14 on the rod 10 into contact with a nut clamping the (otherwise) insulated terminal 15. The closure of the detector-circuit may be utilized to operate a visual signal (such as a lamp), or an audible signal; and, it may be adapted to stop the vehicle by interruption of the motor-ignition, or brake-application.

Title: A machine for high speed sorting or counting of articles

IPC: B07C5/36
Filed: 1962-06-12
Abstract: 954,333. Photo-electric sorting apparatus. MANDREL INDUSTRIES Inc. June 12,1962, No. 22470/62. Heading G1A. [Also in Divisions B8 and G4] Objects 2 such as beans, seeds, capsules or the like to be sorted or counted are picked up by nozzles 10 projecting from a rotating vacuum drum 11 and conveyed past an inspection station 14 (photo-electric as illustrated although reference is made to magnetic electrostatic or other types), the signals from the station after appropriate sensing in a unit 21 and delay in a unit 22 being employed to control a stationary air ejection nozzle 60 which is situated within drum 11 and positioned to aim outwardly through each of nozzles 10 as they are rotated past. Selected objects 2 may thus be ejected to a bin 30, the remainder being ejected to a bin 31 as the nozzles come adjacent a stationary cut-off shoe 33 having a cavity 50 maintained at an elevated pressure by air supply via hose 58. A second cavity 51 maintained at a high pressure by air supply via hose 59 serves to cleanse the nozzles of any product fragments or dirt before further objects are picked up. A stationary interrupter shoe 32 is located beyond the pick-up position and serves briefly to interrupt the passage from each nozzle to the interior of the drum and is effective to cause a single object to seat firmly on the nozzle and any excess objects to drop away. The release of air from ejection nozzle 60 is controlled by an electromagnetically operated valve mechanism 24, details of which are described with reference to Fig. 4 (not shown). Shoes 32 and 33 are supported by mechanism 24 and are urged by springs 39 and 53 to make an air-tight sliding seal with the inner surface of the drum which is ground smooth and oiled. Assembly 24 with shoes 32 and 33 is attached to the end of a vacuum pipe 56 which communicates with the interior of the drum and about which the drum rotates under the control of motor 13. The products are supplied from a hopper 1 to a feed bowl which is rotated by a motor 4. More than one ejecter nozzle 60 and valve mechanism 24 may be provided at different points around the drum to allow for sorting into more than two categories. Reference is made to the use of water and inert gases in place of air to operate the ejector nozzle. The apparatus may be employed to separate any specified number of products by causing the ejector to eject continuously until the specified number is counted by the sensing unit 21.

Each roller comprises a spider 63 covered with sheets 59 so that during the passage of the yarn superfluous dye is expressed and the yarn is stretched longitudinally. Final delivery takes place between rollers 37, 38.

Abstract: 388,061. Improving commutation in dynamo-electric machines. PLATEN, B. C. VON, 99, Ostermalmsgatan, Stockholm.-(Assignee of Glesum Internationale Patent Akt.-Ges. ; Vaduz, Liechtenstein.) Aug. 14, 1931, No. 22979. Convention date, Aug. 18, 1930. [Class 35.] Indicators, applications of.-In a continuous current machine having an open coil winding in which is induced an alternating-current voltage having definite zero voltage intervals, voltage or current impulses set up on incorrect. commutation between separate elements, together forming a commutator brush are utilized to influence the electromotive forces induced in the commutating circuit so as to obtain complete commutation. The Figure shows an armature winding 6 carrying alternating current connected to a rotating two-segment commutator 2, 3 through slip-rings 4, 5. In series with the winding 6 is the armature winding 7 of an alternating current commutation generator 8. The generator 8 has two counteracting field windings 9, 10 fed from a continuous current source 29, 30. The commutator 2, 3 is connected with a continuous current circuit by a brush 13 and a second brush in two parts 14, 15. These two brush parts are connected together by a condenser 16 and a potentiometer resistance 17. The primary windings of two transformers 18 are connected to points in the resistance 17 through oppositely directed rectifiers 20, 211, which may consist of crystals, copper oxide rectifiers - or thermionic valves. The secondary windings of the transformers 18 are connected, if required, through rectifiers 22, 22<1>, to two three-electrode valves 24, 24<1>, the usual grid bias batteries 26, condensers 27 and grid leaks 28 being provided. Each valve controls one of the windings 9, 10 so that as the result of under or over-commutation, current flows in one or other of these windings and a compensating electromotive force is injected into the circuit of the winding 6. In a modification, the windings 9, 10 are provided on an intermediate exciter, the armature winding of which supplies the field of the commutation generator. The condenser 16 or the resistance 17 may be dispensed with. The resistance may be inductive so that the apparent resistance increases with the frequency of the impulses passing therethrough, or it may be adjustable with respect to the frequency. Inductances may also be connected in the primary or secondary circuits of the trans- - formers 18. The impulses set up between the brush parts may influence the commutation in other ways as by introducing condensers, resistances and inductances in circuit or they may be used to indicate the current direction between the brush parts so that the exciting current of the commutation generator can be adjusted manually. The commutation generator may have additional exciting windings chiefly for use at starting. The invention is particularly applicable to motors, generators and transformers of the type described in Specifications 323,498, [Class 35, Dynamoelectric generators &c.], and 360,418.

Modified forms of the apparatus of the invention are described in which (a) the oxygen inlet conduit 16 enters through the opening 24 (Fig. 3, not shown) and (b) the oxygen enters through an annular inlet such as 28 disposed about the gaseous product exit (Fig. 5, not shown). The non-gaseous material may be suspended in carbon monoxide, and the carrier gas may also contain oxygen.

Abstract: 747,465. Fluid pressure railway brakes. WESTINGHOUSE AIR BRAKE CO. Aug. 9, 1954 [Nov. 17, 1953], No. 23061/54. Class 103 (1). In a fluid pressure brake distributer valve for railways, in order to prevent depletion of the control reservoir pressure into the auxiliary reservoir when the charging valve device 9 moves to charging position after final release of a brake application, fluid under pressure from the brake pipe passage 28 will flow to the auxiliary reservoir 3 by way of choke 27, space 26, choke 30, passage 23 and chamber 24, passage 31, chamber 32, encircling the service valve device 7, and the usual communications (not shown). If, during this time, pressure of fluid in the brake pipe passage 28 and hence in passages 21 and 22, which is connected to space 26 through a choke 25, is less than that in the control reservoir 6, the control reservoir will equalize into the brake pipe at a rate controlled by chokes 25 and 27 in series but no dissipation of control reservoir pressure into the auxiliary reservoir will occur, the choke 25 being smaller than the choke 30. Overcharges in the auxiliary reservoirs 3 and 6 may be dissipated to the brake pipe independently past check valves 11 and 10 respectively and through chokes 48 and 42.

Thus the fluxes in the magnetic paths may use the whole of the iron available without the necessity of passing perpendicularly to the laminations. The strips may be continuous and of one width or they may be jointed and of varying widths in which latter case the cross-sections will be of a cruciform shape.
