IPC: B62K1/00
Filed: 1930-09-26
Abstract: 360,137. Unicycles; rail-ring vehicles. PURVES, J. -A., Chilliswood, Trull, Taunton, Somerset. Sept. 26, 1930, Nos. 28901/30, 36210/30, and 20986/31. [Classes 79 (i) and 136 (iii).] A vehicle adapted to be propelled by human power, by an internal-combustion engine, or by electric, hydraulic, or other means, comprises a sphere or spheroid, or preferably an annular part thereof, adapted to roll along the ground and provided within it with a trolley or carriage running on an internal track &c., the vehicle being steered principally by lateral displacement of the load or the major part of it relatively to the central vertical plane of the outer rolling member. The spherical annulus 1, Figs. 1 and 2, may be constructed of a number of spaced circumferential members connected by transverse members and covered by lattice-work to permit fore and aft vision, the outer rolling surface being provided with tyres &c. A carriage 3, adapted to carry an engine &c. 4 and passengers, runs on one or more circular rails 2, its wheels 5 being driven by chain &c. gearing from the engine &c. 4. Steering is effected by a lateral movement of the load, e.g. by rack and pinion mechanism, or by pivotal movement of slings 13, Fig. 5, supporting a platform 14 carrying the engine, passengers, &c. on a trolley 12. Alternatively, the load may be carried by a ring-like member which is provided with wheels to run on the track, and with an inner circular &c. loadcarrying frame adapted to pivot about a horizontal axis. In other modifications, the track 22, Fig. 10, itself is tilted, as by means of control wires or rack and pinion mechanism 28, spring- pressed rollers 26 preventing lateral oscillation. Alternatively, steering may be effected by changes in the angular momentum of one or more flywheels, which are mounted on vertical axes and are provided with braking-mechanism. The vehicle may be driven by the reaction of water discharged by a pump from a pipe, and then re-collected. The vehicle may be driven electrically by means of a motor and batteries &c., or by electromagnetic action between the trolley and its track, e.g. by means of electromagnets, conducting-strips and brushes, &c.

Title: Improvements in silencers for machine guns, and other automatic fire-arms
IPC: F41A21/30
Filed: 1928-10-09
Abstract: 299,449. Wilman, Z. Oct. 27, 1927, [Convention date]. Addition to 289,420. Machine guns. - Relates to devices of the kind described in the parent Specification for subduing sound and flame at the muzzle of a gun. According to the invention, the device comprises a tube 3 screwed to a socket 1 itself screwed to the muzzle of the gun, the tube 3 being provided with valves 14 to prevent the issue of the gases after the bullet, holes 5 for the passage of gases from the tube 3 to a surrounding casing 6, and means for preventing the rush of the gases back into the barrel. Conical baffles 4 may be fitted inside the tube in a known way. The space between the tube 3 and the casing 6 is divided into three chambers a, b, c by partitions 7, 8 attached to the tube 3, and the casing 6 is slidably mounted and can recoil against a spring 10. The.valves 14 are normally held open by a spring 16. When a shot is fired and the bullet passes through this device, gases pass through the holes 5 to the chamber a, and the pressure in that chamber is communicated by pipes 19 to the tails of the valves 14, which are thereby rocked and close the orifice 13 after the discharge of the bullet. The pressure of the gases in the chamber a also checks, the recoil of the gun by its action on the partition 7, and by its opposite action on the rear wall 9 of the casing 6 causes that casing to recoil against the spring 10, thereby enlarging the chamber a and connecting it to an outlet hole 23. Part of the gases from the chamber a also escape to the chamber b through non-return valves in the partition 7. The pressure in the chamber a. is thus reduced to such an extent that a flow back of the gases to the barrel is prevented. At the end of the recoil of the casing 6, the valves 14 are forced open by the positive action thereon of a projection 18 at the end of the tube 3, if they have not already been reopened by the spring 16 on the reduction of pressure from the pipes 19.

Title: Improvements in and relating to optical systems
IPC: G02B27/10
Filed: 1936-10-26
Abstract: 486,111. Optical systems. LAND, E. H. Oct. 26, 1936, No. 29089. [Class 97 (i)] A light-dividing system, particularly for stereoscopic photography or projection, comprises a prism having its hypotenuse face so situated that axial rays, i.e. rays corresponding to the line of separation of the right and left eye images, meet it at the critical angle of total reflection, so that rays to one side of the axis are totally reflected at the said face, while rays to the other side of the axis pass through. The system shown in Fig. 1, comprises two right-angled prisms 10, 11 having their hypotenuses 12, 13 parallel and separated by an air gap. The rays 18 forming the left-eye image are incident on the prism 10 and pass through the system to be focused by the lens 14 on the space 16 of the film 15. The rays 19 forming the right-eye image are received by a mirror 20 and are deviated so as to enter the prism 11, being totally internally reflected at the hypotenuse 13 so as to be focused by the lens 14 on the image space 17. The system also prevents unwanted rays from reaching the image spaces 16, 17. Thus, in Fig. 2, rays 22 which enter the left-eye orifice of the system from a point 21 to the right of the field to be photographed (represented by the points 23, 26) are totally reflected at the surface 12 of the prism and are thereby prevented from reaching the film; and, in Fig. 3, rays 25 entering the right-eye orifice from a point 24 to the left of the field will, after reflection at the mirror 20, pass through the surface 13 of the prism 11. In using the system for projecting stereoscopic pairs of images on to a screen, polarizers 27, 28 may be inserted in the two beams, the spectators then being provided with suitable analyzers. In projection, a single prism could be used to separate the paths of the two beams, such prism preferably being achromatic. Specification 423,874, [Group XL], is referred to.

Title: Manufacture of aromatic carboxylic acid chlorides
IPC: C07C51/60
Filed: 1935-10-22
Abstract: Aromatic carboxylic acid chlorides are manufactured by heating aromatic carboxylic acids containing a negative substituent in p-position to the carboxylic group with at least four times their weight of thionyl chloride in the presence of an inorganic catalyst which favours the elimination of hydrochloric acid, advantageously at the boiling point of thionyl chloride.  Suitable catalysts are the chlorides of metals of the third, fourth and fifth groups of the periodic system, e.g. aluminium chloride, tin tetrachloride or antimony pentachloride.  Examples describe the preparation of chlorides from: (1) terephthalic acid; (2) nitroterephthalic acid; (3) chloroterephthalic acid; (4) p-nitro-, p-chloro-, p-bromo- and p-hydroxybenzoic acid (the chloride of the last-named acid being obtained first in the form of its sulphurous acid ester, which is saponified); (5) 1 : 4-naphthalenedicarboxylic acid; (6) 4 : 4<1>-diphenyldicarboxylic acid.

Title: Improvements in an arrangement for firing from a distance charges of powder or explosive for operating apparatus situated in boreholes
Inventor: SCHLUMBERGER MARCEL
IPC: E21B43/1185
Filed: 1951-12-12
Abstract: 705,002. Selective firing of explosive charges. SOC. DE PROSPECTION ELECTRIQUE PROCEDES SCHLUMBERGER. Dec. 12, 1951 [Jan. 30, 1951], No. 29147/51. Classes 9(1) and 85 In an arrangement for 'the selective firing in sequence of a plurality of charges of explosive, particularly charges for operating apparatus in boreholes such as the sample taking means of a sampling tool, wherein the electrical firing of a charge produces the mechanical priming of an adjacent charge, the unprimed charges are divided into groups, each group R 1 , R 2 , R 3  being inserted into one of a corresponding number of electric circuits 1, 2, 3 which cannot be fed simultaneously. Before the firing operation one charge R 1-1 , R 2-2 , belonging to each of the different circuits, minus one, is primed; on firing a primed charge R 1-1  it mechanically primes a desired charge R 3-1  in the circuit having no primed charge. In the event of a misfire the firing sequence can be maintained, the arrangement being such that the primed charge to be next fired after the misfired charge can prime a charge in each of the unprimed circuits. Before priming the igniters are earthed at both ends. The firing of a charge results in the priming of, at the most, one charge in each series. In the embodiment shown of the sampling tool, on the firing of charge 6-1, sampling means 7-1, which is connected by a cable 8-1 to the body 5 of the tool, is ejected and, in the drawing out of cable 8-1, pulls wire 12-3 that is connected to it clear of the spring contact 10-3 of the igniter R, of charge 6-3, allowing contact 10-3 to engage with the electric cable 3 of firing system. Wire 12-3 passes through cable 8-2 of means 8-1, so that in the event of the misfire of charge 6-1 the subsequent firing of charge 6-2 will prime igniter R 3 . The system may be suitably modified to allow for more than two consecutive misfires.
