Patent GB-377334-A (GB)
Title: Improvements in and relating to automobile road vehicle construction
IPC: B62D37/06
Filed: 1931-05-09
Abstract: 377,334. Road vehicle suspension. DRECHSEL, A., 47, Gabelsbergerstrasse, Munich, Germany. May 9, 1931, No. 13797. Convention date, May 10, 1930. [Class 108 (ii).] The body part of motor cars or trailers is pivotally connected to the wheel axles for rotation about the longitudinal axis of the vehicle and is stabilized by a gyroscope. The body may pivot about a transverse axis in a frame pivoting about the longitudinal axis. Displaceable weights are provided to compensate for one-sided loads. In the form shown in Fig. 6, the car frame 17 is pivoted at 4, 5 to the centres of the front and rear axles. The body 18 is pivoted about a transverse axis 19 (2) in the frame 17. The suspension is preferably weight stable, a low centre of gravity being obtained by employing horizontal motor cylinders with air cooling, front wheel drive and by having the motor placed at the back and the car frame below the axles. To equalize the load a weight 26<1>, e.g. the accumulator, may be moved on rails by ropes controlled by a crank handle. Alternatively a damped pendulum may control contacts in the circuit of a reversible electric motor for moving the weight. The possibility of excessive rotation of the car body about its axes is avoided by buffers. Fig. 2 shows, on the left, an axle 6 provided with shock-absorbing coiled springs or air buffers and pivoted to the car frame at 4 (5), the mudguard 7 being fixed to turn with the wheel. On the right is shown an alternative in which the wheel is supported by springs 9, 10 braced by the inlet piece 8 to which the mudguard 11 is attached, the system 8, 9, 10 rotating about the pin 4 (5). In a further alternative each wheel axle and a cross spring rotate independently on the pivot 4, (5). In Fig. 6 the mudguard 25 is rotatable about a point in the car frame. In a modification, shown in Fig. 4, intended to lessen lateral oscillations, a spring parallelogram suspension 16 for the wheels carries a spring- centred rocking lever 15 in which the pivot pin 4 (5) bears. Vertical oscillations are lessened by a spring suspension which is soft at the middle and hard at the beginning and end of the swing. To compensate for heavy loads additional springs may be employed or in the case of air suspension the air pressure is regulated if desired automatically by a valve adapted to be opened when the springs are overloaded by an arm connected to the springs. Over bad roads the clearance may be increased be letting more air into the chamber of the air spring suspension. When the stabilization devices are not working the pivots of the body may be locked or the body elastically connected to the car frame by springs.

Title: Improvements in or relating to the manufacture of metal halides
IPC: C01B33/08
Filed: 1960-04-20
Abstract: <PICT:0909245/III/1> Metal halides, especially of magnesium, vanadium, tantalum, titanium, aluminium, zirconium, niobium, or beryllium, are prepared by cracking one or more gaseous hydrocarbons in contact with metal oxide particles at a temperature above 900 DEG C., and thereafter reacting the resultant carbon coated particles with at least one halogen at a temperature below 1400 DEG C.  The cracking is preferably effected at 1100 DEG -1400 DEG C.  The hydrocarbon preferably does not contain more than 4 carbon atoms, for example methane, and oxygen or an oxygen-containing gas may also be present.  The gases resulting from the cracking may be burnt to heat the oxide particles.  The oxide particles may be treated in stationary or fluidized beds, or in moving masses.  In Fig. 1, metal oxide particles are preheated in combustion chamber 1 by the burning of cracked gases from chamber 2, and the particles then pass to chamber 2, where they are contacted with hydrocarbon gases entering via line 8, thereby coating the particles with carbon, which then pass to halogenation chamber 3 and contacted with halogen entering via line 13.  The halide product is either withdrawn via line 7, or if in the vapour from either via line 15 or via heat exchanger 16 and line 18.  The oxide particles are preferably below 20 mm. in diameter.  The halogenation and cracking may be effected in the same zone.

Abstract: 774,626. Polishing machines. CORNING GLASS WORKS. May 13, 1955 [May 14, 1954], No: 13942/55. Class 60 A polishing machine has a length of track 12, a work-piece support carriage 13, a rotatable polishing head 21, means 15 for moving the carriage back and forth along the track progressively to associate the head with different surface areas of the work-piece 14, and means 33 for moving the polishing head back and forth transversely of the track to progressively associate the head with other surface areas of the workpiece. The means 15 consists of a. hydraulic cylinder which is connected by a rod and buffer springs 17 to the carriage 13 which has its direction of movement reversed each time a contactor 35 on the polishing head engages either one of two switch elements 1, 2. The latter control a solenoid actuated valve arranged to reverse the direction of fluid flow to the cylinder 15. The switch elements 1, 2 are resiliently mounted on insulated supports connected to the workpiece 14 which may be a mould for a television picture tube. Two further switch elements 3, 4 serve to reverse a second solenoid actuated valve controlling the cylinder 33 each time they are contacted by the polishing head 21. The cylinder 33 is connected by a rod 32 and buffer springs 17<SP>1</SP> to an arm 31 which causes a cap assembly 28 to rotate about a vertical pivot and hence to move the polishing head transversely of the work-piece. The weight 40 applies pressure to the polishing head which is supported on a horizontal pivot 27 and driven by a belt 26 from an electric motor 25. Each of the switch elements 1 to 4 includes a holding circuit which is broken whenever the oppositely disposed. switch element is actuated by the polishing head. If the carriage 13 or the polishing head 21 should fail to reverse additional switches operated by projections on the rods 16 and 32 stop' the machine. The cylinders 15 'and 33 are supplied by a constant displacement pump through needle valves which are So adjusted that the transverse movement of the polishing head is less than the diameter of its polishing surface for each reciprocation of the carriage 13.

Title: Improvements in or relating to the production of rubber articles from latex
IPC: C08J5/02
Filed: 1944-07-21
Abstract: In the production of rubber articles direct from dispersions, a "zinc amino complex" formed by dissolving zinc hydroxide or carbonate in ammonia, is added to stabilized latex, the amount of complex and stabilizing agent present being adjusted so that the latex thickens, but does not coagulate until the forming operation is complete.  1-10 per cent of the complex may be added depending on the amount of thickening desired.  In the case of commercial ammonia-preserved latex, the ammonia is preferably removed to enable the amount of stabilizer present to be controlled.  A suitable mix for making gloves consists of 160 parts by weight of latex of 60 per cent dry rubber content free from ammonia, 2 parts of sulphur, 0.5 parts of zinc oxide, 1 part accelerator, 5 parts mineral oil, 1 part antioxidant, 0.8 parts potassium oleate, and 12 parts of zinc amino complex made by dissolving 1 part zinc carbonate in 3 parts .880 ammonia.  Formers are dipped and dried for 1-15 min., and the dipping is repeated.  The thickened latex may also be coagulated by heat, e.g. by extrusion through hot nozzles.

Title: Tile fixing adhesive compositions
Inventor: JACKSON BARRY SIDNEY
IPC: C04B28/04
Filed: 1963-04-11
Abstract: A composition for mixing with water comprises 15 to 19 parts by weight of white Portland cement, 1 to 5 parts by weight of calcium fluoride and from 0.2 to 0.5 part by weight of water-soluble hydroxyethyl-cellulose.  The composition may also include 0.025 to 0.1 part by weight of sulphite lye powder as a wetting agent.  The composition when mixed with sufficient water to form a spreadable mass of dough-like consistency is used as an adhesive in fixing ceramic floor and wall tiles.  The water-soluble type of hydroxy-ethylcellulose is more readily soluble in cold water than thickening agents hitherto used in such compositions and therefore by its inclusion the composition is brought to a useful consistency more quickly and easily by mixing it with water.  The calcium fluoride component retards the initial stiffening of the mortar and thus allows more time for fixing the tiles to the surface.  After the initial retardation, however, the composition sets normally.ALSO:A composition for mixing with water comprises 15 to 19 parts by weight of white Portland cement, 1 to 5 parts by weight of calcium fluoride and from 0.2 to 0.5 part by weight of water-soluble hydroxyethyl-cellulose.

Title: Process for refining steel
IPC: C21C5/04
Filed: 1956-05-10
Abstract: A process for the production of steel in a hearth furnace comprises heating the slag, when the metal is ready for pouring, at such speed and in such time that it attains a temperature at least 100 DEG C. higher than the metal, and tapping the steel before a balance between the temperatures of the slag and the steel is restored.  The temperature of the metal may be kept sufficiently below the tapping temperature that the superheated slag raises it to the desired temperature just before tapping.  The superheat may be obtained by blowing with oxygen or, in the case of Siemens-Martin furnace by working with highly preheated regenerators.  The treatment may be the final stage of a duplex or triplex process, e.g. a basic Bessemer converter followed by a hearth furnace process, or a basic Bessemer converter followed by a Siemens-Martin process followed by a hearth furnace process.
