Title: A transmission for vehicle trains comprising trailers with driven wheels
Inventor: HUTTER WOLFGANG
IPC: B62D59/02
Filed: 1957-12-31
Abstract: 836,946. Driving trailer wheels. ALLGAIER-WERKE G.m.b.H. Dec. 31, 1957, No. 40446/57. Class 79(2) A transmission for a trailer with wheels driven from a power take-off shaft of a tractor or other motor vehicle comprises a mechanical transmission consisting of shafts, gears and the like, an infinitely variable gearing for equalizing the peripheral speeds of the wheels of the tractor and trailer, and a control rod linkage for varying the transmission ratio of the infinitely variable gearing, the said linkage being connected with a movable member of the hitch which is displaced by the longitudinal forces between the coupled vehicles. As shown the running gear of the trailer comprises a central support member 1, the front end of which supports a draw bar 6 having a hitch eye which is connected with the claw coupler 7 of the motor vehicle 26. The draw bar is longitudinally displaceably mounted on the hitch bar 21 which is held by a collar 22 between two springs 23, 24 which retain it in a central position if no tractive pull is transmitted through the draw bar. The driven wheels 3 are rotatably connected with the power take-off shaft 9 of the vehicle through an articulated shaft 8, transmission shaft 10, bevel wheels 11, 12 and spur gear 13, 14 with interposed infinitely variable gear 15. The gear 15 may be an hydraulic gearing of the axial piston type, with mechanically coupled primary and secondary members. A control lever 16 connects the variable gear 15 to the draw-bar 6 through a rod coupling 20, 19, 18, the double armed lever 19 of which is suspended from a shock absorber 25. By deflection in one or other direction of the lever 16, the speed of the bevel wheel 11 in relation to the transmission shaft 10 can be increased or decreased thereby to adjust the peripheral speed of the wheels 3. In a modification the control lever 16 is actuated by the claw coupling member which is adapted to move axially to and fro against spring pressure. In another modification, the infinitely variable gear is incorporated in a branch of the main power transmitting line, the power transmitted to the gearing 15 being transmitted through a reduction epicyclic gearing arranged co-axially with the main shaft. In another modification a device is provided for clamping the rod linkage, the device being coupled to and operated by a differential locking device and/or braking system of the vehicle. Additional means are provided for varying the transmission ratio of the infinitely variable gearing when the rod coupling is clamped. Specification 745,126 is referred to.

Abstract: 1,263,344. Injection moulding. L'OREAL. 13 Aug., 1969 [13 Aug., 1968], No. 40548/69. Heading B5A. Plastics material is injected under pressure into a receptacle 1 or a mould which is preheated sufficiently to sinter the material applied to the walls thereof and when a parison has formed in the receptacle or mould, excess material is removed and the parison is heated to polymerize the plastics material. The moulded product may be a lining on the inner surface of the receptacle, in which case the walls of the receptacle are precoated with a primary key coating. Alternatively in the case of a mould, an anti-adhesion layer may be used. In the drawing material is injected into the receptacle 1 by a screw 9 rotating in a tube 8 connected to a hopper 10. Air from the receptacle escapes through apertures 3 in a cylinder 2. When the receptacle is full current is supplied to an electromagnetic device 5 to cause a piston 4 to press against the lower end of the cylinder 2, thereby closing the apertures 3. Pressure is then applied to the material in the receptacle by further material supplied by the screw 9. After sufficient time has elapsed to apply a lining to the receptacle, excess material is removed, e.g. by a suction device. Plastics material is prevented from adhering to the piston 4 by cooling fluid supplied through conduits 16. Numerous examples are given of suitable moulding cornpounds with stabilizers and pigments.

In a nut, bolt and washer assembly used in securing together apertured workpieces 12, 30, a non-deformable washer 20 having a concave face 22 adapted for the removal of compressive stresses from the bearing face of the nut 11 is positioned so that the flat face 23 of the washer bears on the surface of the workpiece 12. The concave conic face of the washer is formed with a frusto-conical recess having a cone angle of 172-176 degrees. As the nut is tightened the concave face 22 causes the bearing face 40 of the nut to expand circumferentially and at the same time a few of the threads of the nut nearest its bearing face will become partially disengaged from those of the bolt 10. In a modification the washer has a stepped recess as in Fig. 3 (not shown), the recess having a width smaller than that of the bearing face of the nut and the inner and outer margins of the recess lying on a conic surface having a cone angle of 172-176 degrees.

[Class 81 (i).] Liquid or semi-liquid medicinal products containing iodine in excess of the amount capable of solution in the vehicle at ordinary temperatures are prepared by introducing the vapour of iodine into a vehicle heated in liquid form to a temperature above the vaporization temperature of the iodine. The iodine enters into colloidal solution in the free form. Suitable vehicles or solvents for the iodine are paraffin hydrocarbons, higher olefines, glycerol and glycol. Liquid petrolatum or refined mineral oil is a suitable solvent of the saturated hydrocarbon class, and in a convenient method of preparing an iodine solution is heated to about 320‹ F. and finely powdered iodine is then added with agitation whereby vapours of iodine are generated and absorbed. For the preparation of nasal &c. sprays small quantities of menthol, phenol and eucalyptol may be added to this solution. Petroleum jelly, paraffin wax, stearic acid &c. may be added to the solution in petrolatum for the production of salve-like preparations. In preparing a solution in glycerol, tannin is added and the temperature employed is between about 230 and 280‹ F. Phenol and menthol may be added to the product.

The term "undried leaves" includes fresh leaves air dried for up to 11 days at room temperature. Thus, the leaves may be heated to 60-170 C. to promote the activity of naturally occurring enzymes in the leaves, the heating preferably being effected for not more than 3 hours, best 20-60 minutes. This heating may be effected under dry or wet conditions. In an alternative method the leaves are heated to 25-50 C. for 10 minutes to 10 hours in the presence of an acidic or neutral buffer. A third method involves the use of an added enzyme, an extract of the undried leaves being heated at 25-50 C. in the presence of a #- glucosidase or a crude enzyme thereof. Solvent extraction to recover the oleandrin may be effected with water, an organic solvent or mixtures thereof. After working up, the oleandrin may be separated from other constituents by column chromatography.
