Title: Improvements in or relating to thrust and/or lift producing devices for use in a fluid medium
IPC: F03D5/02
Filed: 1957-07-23
Abstract: 859,007. Endless band propellers. MATTHEWMAN, W., and WILLIAMS, E. H. Oct. 22, 1958 [July 23, 1957 ; Nov. 23, 1957 ; Jan. 1, 1958], Nos. 23214/57, 36563/57 and 4/58. Class 4. A lift and/or thrust producing device for use in a fluid medium comprises a plurality of blades travelling in unison through the medium round an endless path, each blade being pivotable about a hinge between an operative, position on a working run in which the working surface of the blade is held facing the direction of travel, and an inoperative position on an idle run in which the blade is held edgeon to its direction of travel, the blade having portions of its working surface on each side of its hinge. In the Figure, which shows an application to lifting aircraft three blades 16, 17, 18 are supported between two flexible chains 14, or bands, (one only shown) by hinge axles 15. The chains run over sprockets 12, 13, the latter being rotated by a shaft 11. The arrangement is that only one blade, e.g. blade 16, is on the thrust or lift producing run at any time. This blade moves through the air in the direction of arrow 28 and the pressure on the blade keeps it pressed against a stop 24 integral with one link of the chain 14. On completing the run, a roller 40 on the blade engages a spiral section 42 of a guide surface 41, which rotates the blade relatively to the chain, so that by the time the blade (e.g. blade 17) commences its return run, it is aligned with its direction of travel. This rotation stresses a leaf spring 25 attached to the stop 24, this spring keeping the roller 40 in contact with guide 41. When roller 40 leaves guide 41 at the end of the return run (e.g. blade 18) the leaf spring rotates the blade to abut stop 24 again, in which position it is again held by fluid pressure on the working run. As an alternative to springs 25, a flange 45 may be provided on each blade, having the same effect through aerodynamic causes. In an alternative embodiment, each blade is disposed about its hinge axle 15 so that the stops 24 are disposed towards the inside of the space enclosed by the flexible chains, and the guide rail 41 is disposed outside this space. Aerodynamic effects are relied on to rotate the blade relatively to the chain at the end of the working run. The device may be adjustable to provide thrust and lift, either by tilting of the whole device, or by movement of idling shaft 10 angularly about shaft 11. During the working run, the blades may travel through a duct in which they are a working fit. The devices may be used in contra-rotating pairs. They may also be used totally submerged in a liquid medium. Each blade may be flat and rigid, or may comprise a framework over which rubberized fabric is stretched by tensioning springs.

Title: Improvements in the construction of spring assemblies for the interiors of mattresses or cushions and machine for use in producing the same
IPC: B21F33/04
Filed: 1956-07-27
Abstract: 812,719. Connecting mattress springs. KEEBLE, D. July 4, 1957 [July 27, 1956], No. 23215/56. Class 83 (4). [Also in Group XIV] The invention relates to a tie wire for fastening together the end coils of helical springs forming a mattress, and to a machine for assembling the mattress. A tie wire 11 is formed with V-shaped loops 12 offset from the remainder of the wire and the arms of the V are bent to form hook-shaped parts 13 at the open end of the loops. The tie wires are placed so that the hooks 13 engage the end turns of a row or coil springs and the loops 12 are wrapped about the overlapping end turns of that and an adjacent row of coil springs at the points where the turns overlap. A cross-wire forming a stuffing edge may be secured to the mattress by passing the wire through hooks 13 and wrapping the loops 12 about the end row of springs. Between the loops 12 the tie wires may be crimped for greater resiliency. The machine for assembling the mattress includes a rotatable member 14 having a radial slot 15 to receive the end turns of two adjacent overlapping springs 10 and the loop 12 of the tie wire, clamping slides 22, one on each side of the rotatable member 14, movable over the end turns and tie wire to hold them in position in the radial slot, and means to turn the rotatable member to wrap the loop in the tie wire about the end turns of the springs. The clamps 22 are held in position by guides 24 and are retracted against the action of springs 25, being retained in the retracted position by a pivoted spring catch 26. The member 14 is rotated by a gear-train as shown, driven from a shaft 35, which is also connected to a cam 37 on shaft 38 which engages abutments 36 on the underside of slides 22 and causes the slide to retract. To hold the radial slot 15 in the vertical position when member 14 is stationary, shaft 33 of the gear-train carries, besides the pinion 32, a disc 42 having a recess engaged by spring-loaded detent 43. An assembled row of springs is released by rotation of a lifting plate 45 by movement of a bar 47 abutted by a pin 46 secured to the plate 45. A machine includes a row of applicators as described above, which may be duplicated in inverted position for securing the top end turns of coils, together simultaneously with the bottom turns. Alternatively, after securing one set of end turns together, the mattress may be inverted and the process repeated.

Title: Apparatus for determining the slip of vehicle wheels
IPC: G01P3/60
Filed: 1969-05-07
Abstract: 1,214,751. Measuring slip of vehicle wheels. DAIMLER-BENZ A.G. 7 May, 1969 [8 May, 1968], No. 23252/69. Heading G4H. [Also in Division F2] To measure the slip of vehicle wheels 11, 12 (Fig. 1) having coupled thereto wheels 14, 16 with z and n.z teeth respectively, a pulse from a magnet sensing wheel 14 enables counter 26 to count pulses from a magnet sensing wheel 16 until a further pulse is received from wheel 40. The count is then decoded to give no signal, a signal on lead 41 or a signal on lead 42 depending on whether a count of 50, less than 50 or greater than 50 is obtained to indicate the slip. Similar apparatus may be used for measuring the slip of four wheels by measuring the slip of wheels 12, 52 (Fig. 6) relative to wheel 11 and the slip of wheel 52 relative to wheel 51. The resulting signals on leads 58, 59, 61 are fed to logic circuitry 62 controlling electromagnetic valves in brake pressure lines for the wheels.

Title: Polycondensation method and apparatus
IPC: C08F2/00
Filed: 1964-06-05
Abstract: 1,070,287. Polycondensation apparatus. MONSANTO CO. June 5, 1964 [June 11, 1963], No. 23355/64. Heading B1X. A polymerization column for the continuous production of polycondensation polymers is horizontally partitioned into distinct zones A, B and C, namely a reaction zone, an evaporation zone, and a final zone, and has level control means 28 and 29 maintaining the liquid in zones A and B at a predetermined level. The column is run with different pressures in each zone but with the same temperature throughout. The reaction zone A has a plurality of suspended buckets 16, the output of one bucket becoming the input of the next lower bucket, controlled by standpipe overflows 14. The monomer product from zone A is introduced into zone B through a spray nozzle 20 to impinge against the inner surface of the column, for falling film and flash evaporation with vapours fed off through vent 22 after passing through demister 24. The prepolymer product then passes to zone C which is under a high vacuum and consists of a plurality of sub-zones defined by discs 33 and 34 interconnected by controls 32 and 52. In the upper part of zone C the discs 32 and controls 32 are equivalent to the reaction buckets in zone A, and packing 38 may be provided in cases of low viscosity between discs 33 and perforated discs 34 in the lower part of zone C. The liquid level between the perforated discs is controlled by varying the area of inter-sub-zone gas discharge. Normally gas flows through a cap portion (56, Fig. 3, not shown) which is gas but not liquid permeable or through slot (58, Fig. 4, not shown) of control 52. As the liquid rises the area for gas discharge decreases so increasing the pressure and causing liquid flow through the perforated disc. The polymer is withdrawn from zone C by a screw or gear pump 64. The vacuum source communicates through port 68. The apparatus is applicable to the production of polyethylene terephthalate by carrying out ester interchange between ethylene glycol and dimethyl terephthalate to form bis-2-hydroxyethyl terephthalate monomer (in zone A) which is polymerised under reduced pressure (in zone C). The buckets may be removed from the zone A and a spray nozzle installed to define a dual-zone evaporator, as in a nylon run.

Title: Improvements relating to apparatus for signalling on and controlling trains from thetrack by inductive action
IPC: B61L3/22
Filed: 1947-08-26
Abstract: 665,604. Train control and cab signalling system. THOMPSON, H. A. July 19, 1948. [Aug. 26, 1947] No. 23493/47. Class 105. A train control and cab signalling system comprises a telegraph-type relay actuated from a trackside line wire through an inductive collector A and amplifier B and serving to energize one or other of a set of tuned reed relays R1, R2, R3, the line wire being normally supplied with current of frequency f<SP>1</SP> to energize a silent-type tuned-reed relay R1 but at a distant signal at clear the line-wire current is of a frequency f<SP>2</SP> and actuates a gong-sounding tuned-reed relay R2 provided that a relay D normally held energized over contacts 12/13 of the silent-type tuned-reed relay has dropped, the circuit to the gong-sounding tuned-reed relay R2 including back contacts 21/20 of the relay D. A brake magnet P is in series with the relay D but is slow acting. The driver must therefore manually reset the relay D as soon as the distant signal has been passed so as to re-close front contacts 2/4 of the relay D which are in the circuit to the silent-type tunedreed relay R1. During passage of the distant signal at clear the relays D and P received current over contact 24/25 of the tuned-reed relay R2. but the armature of relay D was dropped beyond the magnetic range. A further gong-sounding tuned-reed relay R3 responsive to line wire current of frequencyÀ#<SP>3</SP> permits the signalman to give coded bell signals to the driver as for instance when stopped at a home signal at danger, it being noted that with line-wire current of frequency f<SP>3</SP> the magnet D and brake magnet P will be de-energized since the tuned-reed relays R1, R2 will not then be closing the contacts 12/13 or 24/25. Specifications 18443/14 and 12228/15, [both in Class 105], are referred to and in the Provisional Specification, Specification 165,493, [Class 105], also is referred to.

Abstract: 788,820. Capsules, applying; making boxes. DETREZ, R. Aug. 16, 1955 [Aug. 17, 1954], No. 23526/55. Classes 18 and 125(2). [Also in Group XXII] A container closure, e.g. a bottle capsule 2 or a box or like bottom is expanded into the neck of the container 1 by means of fingers 3a formed by slots in the lower end of a cylinder 3 and spread apart by the tapered lower end of a plunger 4 co-operating with tapering parts on the internal surfaces of the fingers. After the slots have been made, the lower ends of the fingers are deformed towards the axis of the cylinder to bring the fingers very close together. As shown, a head 6 is lowered by a cam 7 until a sleeve abuts the upper end of the container whereupon an outer sleeve 12 and an adjustable abutment 15 continue to descend, the latter forcing the plunger 4 into the fingers 3a to spread them. This motion is limited by the sleeve 12 abutting the sleeve 9 and any further force exerted by cam 7 is absorbed by a spring link 8. In modifications, the receptacle can be moved instead of the head, the motion may be produced by hydraulic or pneumatic means, or the fingers may hold the capsule prior to insertion in the neck.
