IPC: B60B15/02
Abstract: 132,267. Feuillette, Q. Jan. 18, 1918, [Convention date]. Block tyres.-In wheel tyres of the type comprising two or more rows of blocks i of wood, vulcanized rubber, &c., arranged in staggered order in the channelled rim of the wheel and removably secured by wedges j bearing on the opposed ends of adjacent blocks and held by bolts k passing radially through the rim and nuts l, the wedges are of such a shape and size that spaces are left between the tread blocks. The wedges which are used with wood blocks may be made resilient, and resilient washers are interposed between the nuts and the inside of the rim. The blocks are secured in channels formed by side flanges f, h and a central rib g, and the bottoms of the channels are formed with flat seatings for the blocks. The wheel is adapted for use on soft ground by removing some of the wedges j and substituting spuds m which take the place of the wedges in securing the blocks and project beyond them. In a modification adapted for lighter vehicles, the blocks r are made of vulcanized rubber with end flanges t at the base, and the wedges are in the form headed bolts u bearing on the flanges. The base of each block is reinforced by a metal strip s turned over at its ends where it enters the end flanges t.

Abstract: 1,040,482. Rolling tubes. N.T.W. MISSILE ENGINEERING Inc. April 8, 1963 [April 9, 1962], No. 13812/63. Heading B3M. A method of forming a tubular metal article of circular cross-section comprises drawing an annular blank axially through a sizing die and simultaneously rolling the inside wall of the blank. A blank W is clamped on to a rotatable head C and held within an annular die D, the head, blank, and die being rotated together by a power unit B. A rolling head F is held axially and rotatably stationary inside the die D during rolling. The workpiece is moved axially to the right during rolling, its wall becoming progressively thinned between the die and rollers. A number of rolling passes may take place, the head F being radially expanded between each pass. Three freely rotatable rollers 101 (Fig. 6, not shown) are held in cylindrical cups in the rolling head and are urged inwardly by springs 110. The cups may be rotated to skew the rolls and are clamped in position by bars 103. Radial adjustment of the rollers is effected by axial movement of wedge members 120, projections on the bases of the roller supports co-operating with slots 123 in the members. The blank to be rolled is provided with an internal annular slot adjacent one end to allow the jaws of the clamping head 52 to grip the blank firmly.

[Also in Groups XXII and XXIX] In a hydraulic control apparatus according to the parent Specification in which co-operating pressure members e.g. of a roller or roller andbreast mill are maintained in working relationship by one or more actuators, the means for controlling flow in the power lines and permitting preselection of the pressure and compensating for leakage, variation in viscosity or temperature or back surge comprise a regulating valve controlling, and sensitive to, the pressure in the power lines and a bleed for the fluid in the lines. A gear type pump 3 supplies liquid at a constant pressure to an outlet which is connected to a relief valve 4 discharging to a reservoir 2 and to a pressure stabilising valve 6 which supplies a slightly reduced pressure to pressure regulating valves 12 which supply working pressure to actuators 1 for loading the machine members. Needle metering valves 20 at the working pressure stage bleed liquid back to the reservoir. The stabilising and regulating valves are similar and each comprises two chambers 13, 14 connected by a passage controlled by a valve 16 which is controlled by a spring-loaded diaphragm or bellows 17 which forms one wall of the second chamber 14. One stabilising valve may supply several reducing valves which may be arranged radially around it. Distension of the bellows provides for surge accommodation. The relief, stabilising and regulating valves are adjustable to set the pressure at each stage. The regulating valves may be connected directly to the pump outlet.

Abstract: 797,387. Automatic voltage control systems. BOSCH GES., R. May 8, 1956 [May 9, 1955], No. 14190/56. Class 38 (4). In an automatic control system for a selfexcited D.C. generator in which the field is controlled by a vibrating contact regulator and the cut-out is combined with a load current limited, the limiter increases the energization of the coil of the voltage regulator to reduce the generator output when the load current becomes excessive. The generator 10 supplies an accumulator 13 and other loads through the current coil 33, the frame of the cut-out 16, cut-out contacts 30, 32, and an earth return. The voltage coil 34 of the combined cut-out and limiter is connected in series with the voltage coil 19 of a vibrating contact voltage regulator. Coil 34 is shorted out by the limiter contacts 29, 31 when the load current is sufficient to pull in the armature 26. In a modification, Fig. 2 (not shown), the two voltage windings are connected in parallel and are in series with a common resistor. The cutout/limiter winding is then open-circuited on overload.
