Patent GB-1104280-A (GB)
Abstract: 1,104,280. Magneto-resistive devices. FUJI ELECTRIC CO. Ltd. 7 Feb., 1967 [7 Feb., 1966], No. 5886/67. Heading H1K. The resistance/unit length of the bridging portions 3 of a magneto-resistive device formed of a semi-conducting material including parallelaligned needles 2 of relatively high conductive material, is lower than that of elongate portions 4. The needles are arranged perpendicularly to the axes of the elongate portions 4, and parallel to the axes of the bridging portions 3. The relatively low resistance/unit length of the bridging portions 3 may be produced by relatively large thickness and/or width, or by the provision of metal coatings, e.g. of Au or Ni, on the portions 3. Suitable semi-conducting materials are GaSb or InSb, while the needles may be of iron-, nickel- or chromium-antimonide. The meandering form of the device is produced by masking and etching, additional etching of the elongage portions 4 being employed if the bridging portions 3 are required to be relatively thick.

Abstract: 1,228,476. Pneumatic tyres. DUNLOP CO. Ltd. 3 July, 1968 [5 July, 1967], No. 31839/68. Heading B7C. Compensation for preferential wear at the end nearer the mid-circumferential plane of the near-side bars of a uni-directional tractor tyre tread is provided by adjusting the dimensions and/or arrangement and/or composition of those bars with respect to the bars on the offside creating an asymmetric wear characteristic across the tread. In Fig. 9, an off-side bar has a head portion 2, symmetrical about the midcircumferential plane X-X. A near-side bar 1<SP>1</SP> has an enlarged head portion 3 providing increased ground-contacting area, which may be symmetrically disposed as shown, or off-set to either side of the plane X-X. The leading edge f<SP>1</SP>, extended in the circumferential direction, may blend smoothly with the bar edge h or join therewith via a step i. In a second embodiment (Fig. 10), the near-side bar 1<SP>1</SP> is given greater rigidity by broadening of its base j<SP>1</SP>, k<SP>1</SP>. Increased ground-contacting area is obtained, in a third embodiment, by reducing the angle between the bars 1<SP>1</SP> and the mid-circumferential plane, and increasing the length of the bars. A fourth embodiment uses a harder, more wearresistant material for the near-side bars, and a fifth adds rigidity to these bars by arranging them so that their heads join with either the stems or the heads of the adjacent leading offside bars.

Gases, e.g. air, entrained in the liquid coolant of an I.C. engine cooling system are separated therefrom by incorporating into the system a separating tank 22 which receives an induced flow of coolant from an air cooled radiator 14 having horizontal tubes 17 by means of an arrangement comprising a tube 29, Venturi tube aspirator 32 and U-tube 36. In operation, coolant supplied from the engine 10 through a line 33 to the Venturi 32 creates a suction to induce coolant flow through tube 29 which, as shown, is connected to the outlet header 16 of the radiator. Liquid coolant and entrained gas enters the tank 22 through the end 31 of U-tube 36. The separated gas is vented through cap 35 to atmosphere and gas-free liquid is returned to the inlet 12 of circulation pump 11 by way of return line 38. Coolant from the engine 10 is normally directed to the radiator inlet header 15 through a line 18 which has a thermostatie valve 20. The bottom of the outlet header 16 is connected by line 21 to the pump inlet 12. A common dividing wall 23 provided with an aperture 34 separates the tank 22 from the outlet header 16. A line 39 is provided to direct liquid coolant into the tank 22 when valve 20 is closed. In a modified embodiment (Fig. 2) the separating tank (22) is located adjacent the inlet header (115), a check valve (41) being provided in the gas-free liquid return line (138) to prevent afterboiling occurring. The gas-free liquid return line may be omitted (Fig. 3).

In a motor vehicle hydraulic circuit for supplying from a single pump 9 both a suspension levelling system and a power steering system having an open-centre control valve 8, the two systems are supplied in parallel by pressure lines P 1 , P 2 , and a controllable check valve 16 between a levelling valve 15 and suspension units 22, 23 is arranged not to open if the pressure in the line P 2  is less than that in the suspension units. The check valve 16 has a control line 29 connected to the pressure line P 2  upstream of the levelling valve 15. During normal running the steering system offers too little resistance to fluid flow to create sufficient pressure in the line P 2  to open the check valve 16, but by turning the steerable wheels to full lock enough back pressure can be caused to open the check valve so that the suspension height is adjusted in accordance with the position of the levelling valve 15. A hydropneumatic accumulator 32 may be connected to the pressure line P 2  upstream of a check valve 31 so that sufficient pressure to keep the valve 16 open is retained while the levelling operation is completed.
