In the embodiment shown the tubes are located in bores in the blocks and engage in apertures 21 provided in ears 17 of adjacent blocks. In an alternative embodiment, Fig. 6 (not shown) the blocks do not possess ears, and the tubes engage in apertures 21 provided in plates (23) which span the interfaces of the blocks and are received in recesses 14 in the blocks. In a further alternative embodiment, Fig. 8 (not shown), the tubes are integral with the plates (23) and engage in respective bores in adjacent blocks. All the blocks may be interlocked to provide a self-supporting ring section, or only some of the blocks may be interlocked the remainder being wedged into position to provide an expansion-type ring-section. The segments may have different lengths and some may be wedge-shaped. Adjacent ring sections are connected by means of rods 22 which are received in the aligned tubes 19.

Abstract: 1335372 Distribution valve for hydraulic motor RIVA CALZONI SpA 2 Nov 1970 [7 Nov 1969] 52068/70 Heading F1A A rotary distributor for the supply and return of liquid to the stationary conduits 19 of an hydraulic motor, comprises a rotary member 3 provided with arcuate inlet and outlet slots 16, 17 which register with openings 18 in a non- rotatable plate 4, the plate 4 being provided with sealed recesses 18a around the permanent interconnections between the openings 18 and the conduits 19 whereby the pressure in the recess acts to prevent the contacting surfaces of the member 3 and the plate 4 from separating. The motor is of the radial piston kind having an output shaft 7 rotating the member 3. The slots 16, 17 are in communication with respective passages 10, 11 in a hollow casing, a ring 12 separating the passage 10 from the passage 11. The pressure of liquid from the passage 10 acts on an annular end surface of the member 3 surrounding the ring 12 to produce a force A urging the member 3 against the plate 4. In a similar manner, pressure from the passage 11 acts within the ring 12 to produce a force B. Since the areas of the member 3 separated by the ring 12 are identical, the forces A and B are the same whichever of the passages 10 or 11 is used as the inlet. The ring 12 may be replaced by an apertured plate, Fig.7 (not shown) providing several pressure areas which are summed to produce the forces A and B. Balancing recesses 16a, 17a for the slots 16, 17 are provided.

Abstract: 1,132,290. Forming silica tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 Dec., 1966 [8 Dec., 1965], No. 54475/66. Heading C1M. A hollow fused silica article is made by feeding silica powder into a flame so that molten silica is deposited on an auxiliary fused silica tube surrounding a mandrel made of tungsten or molybdenum, wherein the deposited silica is fused to the auxiliary fused silica tube, and wherein the mandrel and the hollow fused silica article are subsequently separated. During the deposition process, a supply of non-oxidizing gas, e.g. hydrogen, may be fed into the interior of the auxiliary tube to prevent oxidation of the mandrel. The wall thickness of the auxiliary tube may be at least 3 mm. In one apparatus (Fig. 1) the mandrel 1 is clamped in a rotatable holder 3. A fused silica disc 11 is fused to auxiliary silica tube 5 on the mandrel 1 and the molten silica is deposited on to the disc so that a mass of silica 29 is built up around the auxiliary tube. On cooling, the mandrel and silica mass separate by shrinkage. Alternatively (Fig. 2), the mandrel 33 may be rotated about a horizontal axis whilst the supply of molten silica 43 is not moved relative to the mandrel, and the auxiliary silica tube 35 is continuously withdrawn from the mandrel.

Abstract: 1312949 Hydrostatic transmission control DEERE & CO 20 Nov 1970 [22 Nov 1969] 55313/70 Heading F2D [Also in Division F1] An hydraulic drive, e.g. for the grain tank discharge conveyer of a combine harvester, comprises a variable displacement hydraulic motor 1, e.g. a rotary cylinder block, swashplate motor, Fig. 2 (not shown), supplied by a pump 28, the displacement control member 6 of the motor being actuated by a spring-loaded piston 10 in a cylinder 13 connected to an accumulator 35 and, through a throttle 16, to a control fluid supply, e.g. pump 28 or a separate pump, Fig. 6 (not shown), such that, in operation, motor 1 initially runs at maximum torque and minimum speed, and is automatically adjusted to run at minimum torque and maximum speed. In operation, manual valve 31 is opened to connect the delivery from pump 28 to throttle 16 and the hydraulic actuator of valve 26, which then also connects pump 28 to motor 1. Spring 12 biases motor control member 6 to its maximum displacement setting so that motor 1 initially provides maximum torque at minimum speed until, after a time determined by the setting of throttle 16, the pressure builds up in cylinder 13 to charge accumulator 35 and bias piston 10 against spring 12, the time taken for the piston to move member 6 to its minimum displacement position being dependent on the pressure at which the gas chamber of the accumulator is initially charged. In Fig. 2 (not shown), the accumulator comprises a flexible bladder in an extension of the control cylinder on the motor casing and the throttle is formed in a partition between the accumulator and control piston chambers. In Fig. 3 (not shown),  the control cylinder and accumulator are separate and connected by piping to an adjustable throttle. In Fig. 5 (not shown), the accumulator comprises a free piston in an extension of the control cylinder, and an adjustable throttle is provided. In Fig. 7 (not shown), the control piston is double-acting and controlled by a, follow-up servo-valve responsive to the control pressure.
