Title: Improvements in or relating to automobile seat construction
IPC: B60N2/12
Filed: 1957-03-21
Abstract: 806,863. Seats. FORD MOTOR CO. Ltd. March 21, 1957 [April 24, 1956], No. 9309/57 Class 52(2) A Vehicle seat has an angularly adjustable back rest which may be swung forward about an oblique axis extending from a point intermediate of the side of the seat to the back. As shown a front seat has a divided back rest for driver and two passengers respectively, each part tiltable as described below. The inner side of the driver's back rest 21 is connected at the bottom by a universal ball joint to a support 26 carried by the seat frame. Welded to the outer side is a bracket 33 to which is pivoted an L-shaped arm, welded at the lower end to a sleeve 39 pivoted to the side seat frame member 16. Pivoted at 46 to a downward extension 47 of the outer side frame of the back rest is a second L-shaped arm 44 which is embraced in the collar 39 by a yoke 52. A fixed pin 51 extends across the collar 39 and is engaged by notches 49 on the underside of the arm 44. The yoke is connected by a pin to member 58 in which there is an arcuate slot 71 having as centre of curvature a point on the oblique axis of tilt of the seat. A lever 64 is pivoted to the seat frame 16 at 62 and carries a projection 69 engaging in the arcuate slot 71. On raising the lever the yoke 52 is raised against the action of spring 54 and angular adjustment of the back is possible. The adjustment may be made by power means using a rotating screw inside the collar instead of the pin and notch device. The seat may be slidable on a track 18

Title: Improvements in brake mechanism for vehicles
IPC: B60T11/04
Filed: 1926-04-08
Abstract: 266,925. Clark, D'A. M., (Bendix Brake Co.). April 8, 1926. Blocks and shoes acting on drums; compensating for wear; force-transmitting mechanism. - In a vehicle brake, particularly for the steering- wheels of a motor-vehicle, of the kind in which friction members or shoes 24, 26 applied to a drum 10 are connected together by a free pivot 36 so as to anchor at one end or the other according to the direction of rotation of the drum, a centring device for the shoes on release of the brake is adapted yieldingly to engage the pivot between the shoes. In the construction shown, the device consists of a bent lever 54 pivoted at one end 64 to the fixed backing-plate 22 and at the other end connected to a spring 68, the' pivot 36 normally resting in the elbow of the lever 54 and adapted by a wedging action to tension the spring 68 when the pivot is moved in either direction by the application of the brake. The operating cam 30 for the shoes is mounted on a spindle 52, which is carried at the free end of an arm 50 pivoted on a fixed spindle 48 and moves in an elongated slot in the plate 22. Eccentric studs 42, against which abut plates 38 on the shoes 24. 26, are mounted on the plate 22 to form anchoring points for the shoes, and are adjustable to compensate for wear. A spring 46 for returning the shoes into contact with the anchors 42 is connected to the spindle 48. In applying the brake with the vehicle moving, say, in the forward direction. the leading shoe 26 would be carried forward by the drum and pivot about the axis 36, while the following shoe 24 would pivot about its anchoring point 42. Application of the brake is effected by a lever 74 having a ball end 76 bearing against an arm 72 depending from the cam spindle 52 approximately into line with the axis of the spindle 48. In actual practice, the centre of the ball 76 is arranged slightly above the axis of the spindle 48, the effect being that a rocking of the arm 50 and application of the shoe 26 occur, irrespective of the direction of motion of the vehicle, before the cam 30 is effective, so that, in applying the brake when driving backwards, a lost motion occurs before the true leading shoe 24 is applied. The centre of the ball 76 is also displaced slightly from the swivelling axis of the wheel, so that, on a turn, a greater braking pressure is applied to the inside wheel.

Title: Improvements in and relating to the hydrolysis of organohalogenosilanes
IPC: C07F7/08
Filed: 1953-04-07
Abstract: <PICT:0745154/IV(a)/1> In a process for the continuous hydrolysis of one or more organochlorosilanes, the silane or silane mixture 1 and water (per se or containing HCl) 2 are simultaneously introduced at 3 into a circulatory system, containing a pump 4 and heat-exchanger 5, until a continuous overflow of the formed organopolysiloxane and acidcontaining water occurs at 6, whence the overflow materials are allowed to settle at 7 into an upper layer comprising the siloxane which issues at 9, and a lower layer comprising acidulated water which issues at 10, the latter being returned to the circulatory system.  If desired, the acidulated water may be separately distilled to obtain gaseous HCl and a 21 per cent HCl azeotrope which can then be returned to the system.  The process may be operated at 25 DEG  to 80 DEG  C. and at feed ratios of 8 to 13 mols. of water per mol. of silane.  Silanes specified are monomethyl-, dimethyl-, monophenyl- and diphenyl-chlorosilanes. Examples are given.  Specification 575,667 and U.S.A. Specification 2,483,963 are referred to.

Title: Improvements relating to chloride-fluoride fused salt baths
IPC: C25C3/00
Filed: 1956-03-27
Abstract: 813,457. Electrolytic fused salt baths; production of aluminium, titanium and zirconium. PECHINEY COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES. March 27, 1956 [March 30, 1955; July 6, 1955], No. 9546/56. Class 41. Oxygen-containing compounds present as impurities in chlorides and fluorides for use in chloride-fluoride electrolytic fused baths are converted into fluorides by treatment with a strong fluorinating agent, such as hydrogen fluoride, or an alkali metal, alkaline earth metal or ammonium bifluoride, e.g. at 200-600‹ C. A bath containing such impurities may be treated as such, but if chlorides which would be converted into undesirable fluorides are to be used in the bath, they are added in dry oxygen.- free form to the fluorinated other constituents. Thus for refining titanium and zirconium. using a bath of alkali metal and/or alkaline earth metal chlorides, the dry chlorides are mixed with 10 per cent ammonium bifluoride and heated to 300-500‹ C. part of the chlorides also being transformed into fluorides. In the production of aluminium using a chiolite-barium chloride bath, to avoid the production of undesirable barium fluoride, the periodic make-up additions of aluminium fluoride and of sodium and barium chlorides are treated separately. Thus the aluminium fluoride is mixed with ammonium bifluoride and heated at 400- 500‹ C. in a graphite crucible with steady stirring with an aluminium stirrer, and when bubbling has ceased the molten salt is cooled to near room temperature by pouring into an aluminium vessel, whereafter sodium and barium chlorides which have been thoroughly dried at 120 C. are added to it.

The generated microwave oscillation is taken off by a strip line structure short circuited at one end and consisting of parallel conductive strips 11, 13 mounted on an insulating substrate 15, Fig. 3. The anisotropic material 17, which may be a thin plate of Y 3 Ga 0À95 Fe 4À05 O 12 , is located between the strips. In a preferred embodiment, Fig. I, the anisotropic material 1 has two easy axes of magnetization R1 and R2, damped magnetic precession occurring about each axis in turn when the direction of a permanent magnet field H b  between polepieces 7, 9 is modified by an orthogonal magnetic field H p  directed alternately in opposite directions. In a modification a pulsed coil may be substituted for the permanent magnet field. The arrangement may use an anisotropic medium with a single easy axis, in which case the bias field needs to alternate in direction as well as being axially displaced from the easy axis.

As suitable chemicals one or more of the following may be used, alkaline liquids such as caustic soda, or potash, soda ash, calcium hydroxide, and soap solution, a buffer salt such as sodium phosphate, sodium borate, common salt or Glauber's salt being used to moderate the action of the alkaline liquid. Suitable enzymes are those obtained from cereals, such as malt, and those prepared by means of fungi such as aspergillus flavus, aspergillus oryzµ and other aspergillus, penicillium, mucor and rhizopus, and by means of such bacteria as bacillus subtilis, mesentericus group, and bacillus carotovovus. Unwanted bacterial growth may be prevented by the addition to the enzyme bath of a liquid such as toluene or chloroform.
