Title: Improvements in bogies for all kinds of rolling stock
IPC: B61F3/08
Filed: 1923-03-05
Abstract: 194,698. Broussouse, F. L. March 7, 1922, [Convention date]. Axle-trucks and bogies; springs, arrangement of, and mounting bodies on; axle-bearing guiding arrangements.-In a bogie for railway and like vehicles the lateral elements of the bogie truck are constituted by the suspension springs of the bogie, articulated directly to the grease-boxes and having suitably different curvatures and dimensions for the purpose of maintaining a constant distance between the grease-boxes, whatever may be the deflection of the springs. The bolster 10 is connected at each end by two sets of leaf springs 8, 9, each set comprising two upper springs 8<2> pivoted to the top of the greaseboxes 4, 5, and two lower springs 8' connected to the bottom of the same grease-boxes. The pivots 14, 15 are on a diagonal line through the centre of the grease-box, and each upper spring 8<2> in its normal position is convex, and each lower spring 8<1> flat, so that under load, when the upper spring tends to become flat and the lower one concave, the pivots 15 move away from, and the pivots 14 towards, each other, so that the distance between the centres of the axle-boxes remains unchanged.

Title: Improvements in or relating to Paperboard Containers
IPC: B65D65/40
Filed: 1967-02-10
Abstract: 1,173,782. Laminated containers. INTERNATIONAL PAPER CO. 10 Feb., 1967 [21 March, 1966], No. 6503/67. Heading B5.N. [Also in Division B8] A container is formed from laminated sheet material resistant to penetration by fluids and comprising a first outer layer 94 of thermoplastic material, a layer 93 of paperboard, an inner layer 92 of thermoplastic material, a layer 91 of metal, and a second outer layer 90 of thermoplastic material. As described the thermoplastic layers are all of low density polyethylene and the metal layer is aluminium foil. The sheet material is originally in the form of a scored blank from which the container for liquids is produced by folding and heat-sealing (see Division B8). The blank includes adhesive portions which when the container is formed lie in a gable top closure portion and facilitate the formation of a pouring spout. The exposed edges of the blank may be protected by a bead of hot-metal material or by a polyethylene- " Cellophane" (Registered Trade Mark)-polyethylene tape sealed therearound or by immersing the blank edges in a chromium salt solution and drying. Alternatively the edge of the blank is skived away at 9 to expose the edge of the inner face of the layer 92 which, after folding, is adhered to the same surface as the layer 94.
Patent GB-820185-A (GB)
Title: Improvements in and relating to the production of alkyl aluminium sesquichlorides
Inventor: BARCLAY WILLIAM
IPC: E04B7/08
Filed: 1957-02-27
Abstract: Alkyl aluminium sesquichlorides are prepared by reacting aluminium with a primary alkyl chloride in the presence of an inert solvent, the reaction being initiated by a primary alkyl bromide or iodide, suitably in amount from 1 to 30 molar per cent of the total halide used.  It is desirable that the alkyl groups of the alkyl chloride and of the initiator should be the same. The reaction may take place between 0 DEG  and 250 DEG  C., preferably between 50 DEG  and 180 DEG  C.  Suitable solvents are paraffinic and saturated alicyclic hydrocarbons.  The sesquichloride so produced may be dehalogenated by the process of Specification 762,200 to give an aluminium trialkyl without separating the sesquichloride from the solvent.  The example describes the production of ethyl aluminium sesquichloride from aluminium and ethyl chloride using decalin as a solvent and ethyl bromide as reaction initiator.
Patent GB-1413886-A (GB)
Title: Coating of substrates of irregular thickness
IPC: B05D1/28
Filed: 1973-02-09
Abstract: 1413886 Coating uneven substrates; coating apparatus BAYER AG 9 Feb 1973 [10 Feb 1972 1 July 1972] 6556/73 Headings B2E and B2L A process of coating an uneven substrate with a surface layer by the reverse process comprises: producing a deformable, but hardenable surface layer on a support; pressing the layer onto the substrate while the layer is still deformable, uniform contact pressure being applied over the whole contact area where the pressure is being applied; hardening the layer; and removing the support. The substrate may be a sheet e.g. natural or simulated leather, wood, wool or other fleeces, woven or knitted fabrics or surfaces formed thereof, the simulated leather being p.v.c. foam, or p.v.c. or other polymer coated fabrics. The coating is preferably a polyurethane, many details of which are given, and may alternatively be p.v.c., polyvinyl acetate, polystyrene, or acrylate copolymers. The coated support is preferably placed on a conveyor and the substrate is fed from an inclined plate under a brush roller. The brush roller has two helical rows of bristles extending in different direction from its centre and rotates in an opposite sense to the motion of the conveyor. A layer of paper between the. bristles and the substrate prevents the substrate being taken up on the brush roller but smooths out folds and removes air bubbles. Uniform pressure is provided by a tube roller comprising a tubular elastic impermeable tube and rigid gas-tight discs 2 supported on an axial shaft, the roller being partly filled with water to give an excess pressure of 0.1 to 10 atmospheres. Alternatively, the shaft may be hollow and formed with holes so that gas may enter the tube roller to provide the excess pressure.

Title: Improvements in or relating to coin-freed turnstiles
IPC: G07F17/14
Filed: 1925-03-11
Abstract: 240,724. Deluce, S. A. N. March 11, 1925. Turnstiles.-Turnstile arms c are locked by a bolt i pressed by a spring j into engagement with one of four notches e' in a disc e mounted on a squared portion of the turnstile spindle b. When a coin is inserted in a slot n' and a handle n<3> pulled, a lever k is actuated to withdraw the bolt and allow the arms to be rotated through 90‹, the coin being then released and the turnstile locked by the bolt engaging in the next notch. The bolt i is held in retracted position during the movement of the arms by a detent p engaging a forked shoulder i' on the bolt. The detent is tripped to free the bolt by tappets g' on a disc g which is mounted on the spindle b engaging an arm p<2> on the detent. A ratchet wheel f engaged by a pawl v prevents backward rotation of the arms. The arms c are stopped in the proper position to close the stile by a spring-pressed plunger bearing against a square collar s on the spindle b. Coin action, mechanical-connection; coin-discharging mechanism.-The coin forms a connection between an abutment n<2> on a sliding plate n operated by the handle n' and a slide l with which the lever k engages. Just before a notch e<1> comes into line with the bolt i a cam e<2> provided on the disc e in advance of each notch moves the bolt further back thereby moving the slide l by means of the lever k to release the coin which drops into a money-box. The bolt is thus prevented from being held back by onecoin while the turnstile is turned to admit more than one person.

Title: Improvements in or relating to packaging machines
IPC: B65B9/20
Filed: 1957-02-27
Abstract: 839,014. Converting rotary into oscillatory motion. FRANK, C. A. Feb. 27, 1957 [Feb. 27, 1956], No. 6595/57. Class 80 (1). [Also in Groups VIII, XVII, XVIII and XL (b)] A device for giving an adjustable stroke oscillatory motion to a walking beam 17 in a packaging machine (see Group XVII) comprises a helical cam 176 driven by a motor 198 through bevel gears 178, 180, the cam causing a slider 183 to travel back and forth on rods 181. The cam, slider and rods are mounted in a housing 170 which is rotatable relative to the remainder of the device by worm-gear means 191, 193. The slider 183 carries a roller 185 which gives reciprocatory motion to a further slider 187 movable on fixed vertical rods 188. The slider 187 oscillates the beam 17 through a roller 26 attached to an arm 17<SP>1</SP> fixed on the beam pivot shaft. When the rods 181, 188 are parallel, the maximum range of oscillation of the beam 17 is produced, but as the angle between these rods is increased by rotating the housing 170, the oscillation is reduced until, when the rods are at rightangles, it is substantially zero.

Title: Improvements in and relating to automatic talking machines
Inventor: GUEST LAWRENCE VINCENT
IPC: G11B17/16
Filed: 1958-02-28
Abstract: 839,666. Automatic gramophones. BIRMINGHAM SOUND REPRODUCERS Ltd. Feb. 17, 1959 [Feb. 28, 1958], No. 6597/58. Class 40 (2). In an automatic gramophone of the kind described in Specification 823,749, means for stopping the machine after the last record has been played comprises a stop plate 23 and a cut-off lever.35 mounted for rectilinear and swinging movements during an automatic cycle such that they follow one path while the spindle of the record steadying arm is in raised position, and in another path to stop the machine when the said steadying arm spindle is in lowered position. Operation of a start button 26, Fig. 1, draws a latch lever 18 down to move a switch lever 15 to the ON position, and at the same time latches itself behind a pin 30. During an automatic cycle a plate 11 oscillates to and fro, and while records remain on the centre post, the plate 23 and lever 35 remain in the relative positions shown in Fig. 2. When the last record falls to the turntable (at a late stage in the automatic cycle) lever 35 passes, under the influence of a spring 38, partly into a notch 32, Fig. 3, on the steadying arm spindle 9, but is limited in such movement by a pin 41, Fig. 8, and serves to limit swinging movement of the stop plate 23 acted upon by a spring 45. After the return movement of plate 11 a projection thereon engages a pin 43 on lever 35 and moves the latter longitudinally by means of a pin-and-slot mounting 36 so that the lever 35 makes a further rotary movement to embrace pin 41 and permits stop plate 23 to move likewise, as shown in Fig. 6. At the end of the following automatic cycle, i.e. when the last record has been played, a projection 47 on plate 11 engages a pin 46 on stop plate 23 and moves it longitudinally to release, via a pin 20, the plate lever 18 and stop the machine.

Title: System for controlling the firing of non-guided projectiles
IPC: F41A19/68
Filed: 1972-02-14
Abstract: 1376018 A firing control system THOMSONBRANDT 14 Feb 1972 [17 Feb 1971] 6830/72 Addition to 1164107 Heading F3C A firing-control system for non-guided projectiles comprising an array of tubular projectile launchers clustered about a main axis, tracking means for ascertaining the location of a target, computing means responsive to the tracking means for calculating the aim-off angle for the launchers and driving means controlled by the computing means and operatively coupled with the array for maintaining the axis trained along the aim-off angle. The array is divided into a plurality of groups of launchers, the launchers of each group being trained on the same area of space which area is different from the area on which any other group of launchers is trained. Preferably the launchers are fired in pairs, the launchers of each pair coming from different groups and being diametrically opposed to each other with respect to the main axis. Triggering means may be provided which are automatically actuated by the computing means during a predetermined firing period. The tracking means comprises a tracking radar 2 controlled by a computer 1, input signals determining the azimuthal sweep and the speed of azimuthal rotation of the aerial 3 of the radar and the target range d within which interception is to take place being fed manually into the computer. The computer 1 feeds a position extrapolator 5 which pre-calculates the aim-off angle, a range plotter 6 which determines when the target is within the firing range, and an area projector 7 which establishes the probable error in the aim-off angle. The output of the extrapolator 5 controls a tracking drive 8 of the gun 13 and the range plotter 6 a trigger stage 9. The area projector 7 controls the operation of a group selector 10 which selects the launchers to be fired in view of the error established by the area projector 7. Outputs from the group selector 10 and trigger stage 9 control a firing stage 11. Several examples of the groupings of the launchers are disclosed together with salvo firing data and the area in space covered by projectiles from the groupings (Figs. 3 to 7 and 10 to 19, not shown). Adjacent launchers may diverge from each other.
