Title: Improvements in or relating to spring suspensions for motor driven vehicles
IPC: B60K17/04
Filed: 1921-04-28
Abstract: 175,924. Perfecto Gear Differential Co., and Starr, C. E. April 28, 1921. Transmission gear of invariable ratio; spring drives.-The driving-gear and the spring suspending-member are constructed and arranged to cause the direction of application of the load, as supported from the driving-axle of the vehicle, to be automatically inclined forwardly or rearwardly of the supporting axle when the driving wheels meet obstructions in the roadway to assist in driving the wheels over these. Enclosing the driving-axle 1 is a stationary housing 2 surrounded by a rotatable sleeve 3 formed at its outer end with a triangular flange 4 on bearing pins 5, in the apices of which are mounted planet pinions 6 meshing with a central pinion 16 keyed on the end of the axle 1 and an internally-toothed ring 13 fixed to the wheel hub 9'. Pinned to the inner end of the sleeve 3 is a collar 35 having depending lugs 36 between which is pivoted a shackle 38 gripping the centre of a longitudinal spring 39 pivotally connected at its ends through links 40 to brackets 31, 41 depending from the frame members 32. To prevent longitudinal displacement of the wheel relative to the chassis, the cover 28 of the brake drum 18 has an extending arm 30 pivoted at its end to the bracket 31. The arrangement is such that rotation of the axle 1 tends to rotate the planet pinions 6 and sleeve 3 in the opposite direction, the tendency being counteracted normally by the attachment of the spring 39 to the sleeve 3, but when the wheel encounters an obstacle some rotation occurs and the spring is thrust forwards to assist in overriding the obstacle.

Title: Improvements in and relating to lens systems
IPC: G02B13/18
Filed: 1946-04-24
Abstract: 611,636. Lenses. NAAMLOOZE VENNOOTSCHAP OPTISCHE INDUSTRIE DE OUDE DELFT. April 24, 1946, No. 12367. Convention date, Sept. 5, 1942. [Class 97 (i)] In lenses having at least one aspherical surface, the difference in the refractive indicies of the media on either side of the surface for the mean wavelength of light used is at the most 0.3. This minimizes refractive errors due to errors in the aspherical surface. As shown, a planoconcave lens C is separated from a lens E having an aspherical surface 4 by a layer D of cement such as Canada balsam, synthetic resin or gelatine or a layer of liquid such as water, the refractive indices fulfilling the above condition. The lenses may be formed by coating a surface with cement and pressing the other to the cement. Alternatively, two complementary aspherical surfaces may be formed by a thin layer of cement.

Abstract: 611,173. Footwear. KAMBORIAN, J. S. April 24, 1946. No. 12377. Convention date, Sept. 22, 1943. [Class 17(ii)] The lining ply lb of a shoe upper is permanently united by an inseam 6 to the margin of a thin flexible sock lining 5, the outer ply 1a of the upper being free from the upper lining at least at one end of the shoe, so that an end stiffening element 4 with a substantially horizontal flange 4a may be interposed between the upper and its lining at the free end with the flange underlying the inseam. The shoe may be force-lasted over a last 2 inserted therein, a middle or platform sole 11 being secured by adhesive to sock lining 5 and a cover or wrapper 7 which may be attached to the upper la or integral therewith being pulled over the side edges of the sole 11 and its edges a turned in and secured to such sole. An outer sole S and heel are then attached. The wrapper 7 may be in two separate portions one at the heel end and the other at the forepart. Where a heel stiffener is employed this may be in two parts the horizontal flange portions extending for the full width of the shoe and overlying one another.

Patent GB-712697-A (GB)
Title: Improvements relating to the production of silicones
IPC: C08G77/00
Filed: 1951-05-28
Abstract: Polysiloxane resins are prepared by reacting an organo silicon compound of the formula R2SiX2 with a silicon orthoester, or an organo silicon compound of the formula R2Si(OR1)2 with a silicon tetrahalide, X being halogen, R an alkyl, aryl, aralkyl or alkaryl radical and R1 an alkyl or aryl radical.  An alkyl or aryl halide is eliminated. In modifications a compound of the formula RSiX3 or RSi(OR1)3 may also be used or mixtures of two or more bifunctional compounds with both a silicon tetrahalide and a silicon orthoester. A compound R2SiX2 may be partially condensed with a silicon orthoester and a compound R2Si(OR1)2 partially condensed with silicon tetrachloride and the two systems then mixed and condensed with each other.  The reactions may be catalyzed, e.g. by aluminium or ferric chloride and may be effected in solution or otherwise.  The yield (as final baked resin) of resins prepared by the method of the invention is favourably compared with the yield of corresponding resins prepared by a hydrolysis method.  Examples: (1) A mixture of dimethyldiethoxysilane, ethyl orthosilicate, diphenyldichlorosilane and silicon tetrachloride, of R/Si ratio 1.6, was heated in the presence of aluminium and ferric chlorides. Toluene was added and the mixture poured into iced water to eliminate residual chlorine and catalyst.  The resin, after filtering and removing solvent, gave fairly hard coatings on baking at 250 DEG  C.  (2) A mixture of silicon tetrachloride, dimethyldiethoxysilane and diphenyldiethoxysilane and a mixture of ethyl orthosilicate, dimethyldichlorosilane and diphenyldichlorosilane were separately heated in the presence of aluminium and ferric chlorides until about half the chlorine had been eliminated and the two products then combined.  Heating was continued, in later stages in the presence of toluene, until 2 per cent. of the original chlorine remained.  The product was then treated as in Example (1).  The initial R/Si ratio of the two mixtures was 1.4.  (3) A mixture of dimethyldichlorosilane, diphenyldichlorosilane, ethyl orthosilicate and silicon tetrachloride, of R/Si ratio 1.3, was heated in the presence of aluminium and ferric chlorides, in later stages in the presence of p  toluene and additional ferric chloride, until the chlorine content had fallen to 4 per cent. of the original value. The product was then heated as in Example 1.

Abstract: 1,072,813. Transformers and inductors. MARRISON & CATHERALL Ltd. Feb. 8, 1966 [March 24, 1965], No. 12426/65. Heading H1T. [Also in Division E2] A metal strap for laminated C-type and E- type cores is held in tension by two brackets, one attached to each end of the strap, and tension applied by screw means passing through both .brackets. In the C-core of Fig. 1, each bracket 3 is of sheet metal bent to have a base integral with two tapering sides 4, with extensions (6), Fig. 2 (not shown), at one end bent inward to form an apertured bridge 7. The lower edge of the bridge 7 is above the upper surface of the base (5) to provide a transverse slot (11). The strap 2 is passed between the sides and through the slot (11) and is looped back under the bracket and up through a second transverse slot (12) provided midway along the base (5), so that each end of the strap is held in frictional engagement between the main part of the strap and the core surface, particularly round the adjacent curved corners of the core. The tension screw means is a bolt 9 passing through the aperture in each bridge 7. Alternatively the bracket may be bent such that the sides and bridge are integral and the base is formed by bending part of the sides inward, which may then be welded together, (Fig 5, not shown). The brackets may be die-cast and several of the tensioning devices may be applied to one core.
