Title: Improvements in an appliance for testing vehicle tyres and road surfaces more particularly at very high speeds of travel
IPC: G01M17/02
Filed: 1936-06-15
Abstract: 460,001. Testing physical qualities of materials. SEIDL, E. June 15, 1936, Nos. 16675 and 16676. Convention dates, June 15, 1935 and May 28, 1936. [Class 106 (ii)] A device for testing wheel tyres and road surfaces comprises a rotating frame in which the wheels are mounted so as to bear on the inner surface of a hollow body forming the track, the centrifugal forces arising during rotation of the frame acting wholly or approximately in the middle plane of the running wheels. The track a forms the inner surface of a vertical cylinder. In special cases a hollow cone or allied shape may be used. The track may be of concrete or ferroconcrete on which a coating of asphalt, metalling, &c. may be disposed. The track may be preferably formed from segments between which air-gaps are left and behind which are disposed substances used in road construction such as broken stones with sand or soil sub-support peat, &c., the exterior surround a<2> being solidly made of ferroconcrete or masonry. The shaft b of the carriage c is fixed in a foot plate bl at an angle to the vertical. The foot plate may be rotated by a worm gear e. The carriage c which is jacketed with sheet metal to be of lenticular form to decrease air-resistance is an iron or girder construction in which the driving motors f for the running wheels d are arranged. The openings i<1> out of which the wheels project are jacketted in a stream line manner. The wheels d are arranged at the end of levers k pivoted in the structure. The motor to which current is supplied by way of a slip ring b, drives the wheel through bevel gear m, shaft n, cardan shaft g, and bevel gear o. The wheels d have their middle sectional planes perpendicular to the axis of the carriage. The levers are provided with counterweights l which if desired can be adjusted during the drive so that the force of the pressure against the track is about equal to the fraction of the weight of the actual vehicle bearing on the running wheel. Spring tensioning devices or air-cylinders may be used instead of the levers. The inclined position of the shaft b enables wear to take place over a broad band of the track.

Title: Improvements in spraying apparatus
IPC: F23G7/04
Filed: 1946-06-03
Abstract: 612,864. Spraying-apparatus. BABCOCK & WILCOX, Ltd. (Babcock & Wilcox Co.). June 3, 1946, No. 16771. [Class 69 (iii)] [Also in Group XXIV] In apparatus for uniformly spraying the side and rear walls of a chemical recovery furnace, the liquor supply pipe 16, Fig. 2, is connected to a nozzle producing a substantially flat spray and given rotary oscillatory movements, about its own axis B-B and a horizontal transverse axis A-A respectively, by two driving means operated at a substantially constant velocity between extreme points of travel of the pipe. The pipe 16 is rotatably and detachably supported in bearings 36, 37 of a frame 35 and connected by a toggle-clamped joint 21, swivel joint 23 and piping to a swivel joint 27 through which and a trunnion bearing 32 the axis A-A passes. The frame 35 is reciprocated by linkage 45, 46, Fig. 1, from a cam roller 53 driven from a cam 54 by a constant-speed motor 58, the cam being such that uniform velocities of the rod 46 are produced. A casing 52 freely mounted on the cam-shaft 47 having a sleeve 51 houses the cam and rod 46 and encloses a spring urging the rod against the cam. To vary, even during operation, the swept angle of oscillation, the lever 45 is slotted and clamped by a hand wheel to a collar freely mounted, but retained, on a fulcrum rod 47 rigidly secured to a second collar adjustably clamped to a slotted base-plate 48. A turnbuckle in the rod 42 effects minor adjustment of the stroke. Similar adjustable linkage 61, 64, Fig. 2, connected at the intersection of the axis A-A and pipe 16 produces rotary strokes of the pipe from a cam 66 driven from the motor 58 90 degrees out of phase with the cam 54. The nozzle and spreader plate are arranged as described in Specification 612,865, with the spray horizontal at the top and lowermost positions of the pipe and inclined in turn to each side during upward and downward strokes. The pipe 16 may be released for replacement by breaking the joint 21 or by removing latch pins on the rods 42, 61 and releasing the toggleclamped joint 31 and bearing 32.

Title: Improvements in automobile headlights
IPC: F21V5/00
Filed: 1920-06-21
Abstract: 145,498. Corning Glass Works, (Assignees of Churchill, W.). Jan. 12, 1917, [Convention date]. Lenses.-In a vehicular headlight in which the light source is located at or around the focal point of a mirror for projecting a parallel beam of light, the lantern front is formed with horizontal prisms whose refractive power is sufficient to refract the light rays downwardly to an amount at least equal to the maximum upward divergence of rays due to the dimensions of the light source. The face of each prism is inclined at a greater angle at the centre than at points farther away, so that the refractive power of the prism is less at its ends that at the centre. In one form, in which a lantern front has fifteen prisms C formed by stepping its rear face, the central parts of the front faces of the seven central prisms are inclined at an angle of 6 degrees, whereas the central parts of the front faces of the remainder decrease gradually to 2 degrees for the top and bottom prisms. Ribs having lateral light diffusive power may be formed on the cover glass. In one form, the ribs are parts of cylinders whose axes are at right-angles to the length of the prisms and at an angle of 2 degrees to the underlying prism. The lower part of the chamfered edge of the lantern front is sand-blasted or otherwise matted to prevent upward deflexion of light.

Title: Methods and apparatus for banding packages of expansible material
IPC: B65B13/06
Filed: 1968-04-08
Abstract: 1,218,423. Banding machine. TITAN EISENWARENFABRIK G.m.b.H. 8 April, 1968 [8 April, 1967], No. 16836/68. Heading B8C. [Also in Division A4] Band sections of predetermined length are fed into a band guide surrounding a package of expansible material, compressed by a plunger 17 in a baling chamber, and the ends of each band section are interconnected before the package is allowed to expand to tighten the band. Band feeding and cutting.-A band 27 having recesses 96 defining the sections, Fig. 7, is fed vertically downwards, Fig. 3, from a coil between pairs of pulley wheels 42, 43 mounted on pivoted levers 35, 36 and driven by a pinion 56 through gears 54, 54<SP>1</SP>. The minimum distance between the two wheels 42 and the two wheels 43 is determined by spacer and spring devices 59, 63 and 61, 64. The band is fed through a slot 92 in a cutting device 88, Fig. 5, having sliding catches 93 which engage in the recesses 96 in the band. The device 88 is then carried downwardly on columns 89 by the band against the action of springs 90 and engages switches (not shown) to stop the feed and activate a piston 97 which pivots a lever 99, causing blades 106, 107 to cut the band. The lever also moves slides 111, the bevelled ends of which engage in recesses 113 in the catches 93 to move them apart. The grip on the band is accordingly released and the springs 90 expand to push the device 88 upwardly. The piston reverses the movement of lever 99, the arms 111 initially remaining stationary. The catches 93 are then released ready to engage the next recesses in the band. Band guiding.-The band is fed into a guide 116, Fig. 1, which has doors (119, 120), (Fig. 2), which may be opened to remove manually the band end. The band passes along a pivotable guide 118 and into guides 133, 30, 29, 31, 134 in the baling chamber. The position of the corner guide 31 is determined by the final position of the plunger 17 which carries the guide 31 against the action of a cylinder 131. The guide 29 is pivoted at 128 and is swung out of the path of the plunger 17 by a piston-rod 130. After the band ends are interlocked, an end plate 12 of the baling chamber is raised and the package is pushed out by the plunger 17. An abutment 126 on the end plate 12 pushes the pivotable guide 118 aside. To bind a package at more than one location, a plurality of band sections may be fed at the same time into corresponding guides. Alternatively, the banding apparatus may be displaced along the package. All the walls confining the compressed package may be movable. A wrapper may be applied before or after banding. Air nozzles may be provided to clean the chamber after discharge of the package.

Title: Improvements relating to electrical circuit arrangements utilising ferromagnetic cores
IPC: H03K23/76
Filed: 1956-06-01
Abstract: 824,190. Circuits employing multi-stable magnetic elements. GENERAL ELECTRIC CO. June 1, 1956 [June 1, 1955], No. 17010/56. Class 40 (9). [Also in Group XIX] A counting circuit with automatic reset comprises a ferromagnetic core 10 having a winding 12 in series with a resistor 21 and a winding 14 in series with a capacitor 24 connected in parallel across terminals 17 and 18 to which pulses are applied. The voltage and time duration of the pulses is such that a given number of pulses is required to take the core from a given initial stable state to saturation. While the core is being moved towards saturation only a small voltage is developed across resistor 21 and an analysis of the circuit is given to show that, by suitable choice of components and in particular by making the number of turns of winding 12 less than the number of turns of winding 14, this small voltage need not produce an output across condenser 24 following the end of an input pulse. When the core is saturated, a pulse generates a voltage across resistor 21 sufficient to charge condenser 24 which discharges on termination of the pulse and is such as to reset the core to its initial stable state. The initial stable state may be reverse saturation and may be set by means of a D.C. source 27 used to charge the condenser 24. The circuit may be cascade connected with the output taken from across resistance 21 or capacity 24. The output may be taken from a third winding on the core 10 connected to energize a resistance in series with a rectifier. To prevent voltage being fed back to the pulse source when the core 10 is reset a rectifier may be included in the lead 11.

Title: Improvements in and relating to the production and use of vat dyestuffs and intermediates
IPC: C09B5/48
Filed: 1930-06-04
Abstract: Chloraminoanthraquinones; indanthrones.-Anthraquinone derivatives are made by condensing a chlorinated phthalic anhydride (other than 4-chlorphthalic anhydride) with chlorbenzene in presence of aluminium chloride, mononitrating the product, reducing the nitro group to an amino group, and cyclizing the product.  The mixture of chlorinated a - and b -aminoanthraquinones thus obtained is separated by fractional crystallization from sulphuric acid, and the products condensed to indanthrones chlorinated in the outer benzene ring, by treating with a copper catalyst and an acid-absorbing agent, such as sodium acetate or carbonate, in an organic solvent such as nitrobenzene, the condensation being preceded, in the case of the b -amino compound, by halogenation in the a -position.  In examples, 4 : 5-dichlorphthalic anhydride is condensed with chlorbenzene, nitrated, reduced with ferrous sulphate and ammonia, and the product heated with sulphuric acid to effect ring-closure.  By careful addition of water, 2 - amino-3 : 6 : 7 - trichloranthraquinone is precipitated and filtered off; the filtrates, on further dilution, yield 1-amino-2 : 6 : 7-trichloranthraquinone.  The first-named product, on bromination in dilute sulphuric acid, yields 1-brom-3 : 6 : 7-trichlor-2-aminoanthraquinone, which is condensed to a product, probably 3 : 31 : 6 : 61 : 7 : 71-hexachlorindanthrone, by heating with copper chloride, soda-ash, and nitrobenzene.  The 1-amino-2 : 6 : 7-trichloranthraquinone yields, in a similar manner, a product which is probably 6 : 61 : 7 : 71-tetrachlorindanthrone, without previous bromination. Specification 330,217, [Class 2 (iii), Dyes &c.], which briefly describes the preparation of 3 : 31 : 6 : 61- (or 7 : 71)-tetrachlorindanthrone from 4-chlorphthalic anhydride and chlorbenzene, is referred to.  The Provisional Specification gives detailed examples of this preparation.
