Title: Improvements in and relating to hydraulic relief valves
Inventor: TOWLER JOHN MAURICE
IPC: G05D16/10
Filed: 1953-06-06
Abstract: 783,413. Hydraulic systems; valves. ELECTRAULIC PRESSES, Ltd. May 21, 1954 [June 6, 1953], No. 15655/53. Classes 69 (2) and 135. A relief valve in an hydraulic system comprises a normally closed closure member subjected to the pressure in the system and loaded by a body of liquid trapped against bodily displacement which has a volume such that under pressure it is compressed to permit the opening of the valve when a predetermined pressure in the system is reached. The relief valve comprises a valve plunger 2 slidable in a body 1 having a connection 3 to system pressure and an exhaust port 10 and is loaded by a light spring 6 housed in a chamber 4 connected at 5 to a vessel 11, Fig. 4, in which a considerable volume of liquid is to be trapped. The relief valve 32, and vessel 11 are included in a system having a continuously rotating pump 29, a double-acting ram 33 controlled by a manuallyoperable valve 36 and a pair of master control valves 30, 31. Each master valve comprises a casing 12, Fig. 2, having first and second inlet ports 15, 17 and first and second outlet ports 18, 19 and a fixed ported sleeve 13 mounting a valve plunger 14 loaded by a spring 22 against system pressure admitted through the port 15. The only difference between the valves 30, 31 is that the valve 31 is more lightly loaded than the valve 30. With both valves in the position shown in Fig. 2, system pressure is transmitted through their ports 17, 18 to the vessel 11 and chamber 4. On movement of the valve 36 to connect ram cylinder port 35 to system pressure the ram is raised in its cylinder and at the same time system pressure is directed to the underside of the plunger 14 of the valve 31. When the ram reaches the end of its upward stroke, system pressure builds up and overcomes the lighter spring of this valve to raise the plunger thereof and cut communication between its ports 17, 18 and so isolate the vessel 11 and chamber 4 from the system. Any subsequent increase in pressure in the system will compress the liquid in the vessel 11 and chamber 4 to permit the opening of the relief valve. On movement of the valve 36 to connect ram cylinder port 34 to system pressure the undersides of the ram and the plunger 14 of the valve 31 are connected to exhaust. The ram falls in its cylinder and the plunger 14 resumes its initial position to again interconnect the ports 17, 18. When the ram reaches the end of its downward stroke pressure beneath the plunger 14 of the valve 30 builds up to raise this plunger to isolate the vessel 11 and the chamber 4 from the system and as before on any subsequent rise in pressure the relief valve will open. The ports 19 of the valves 30, 31 are connected to exhaust and any excessive pressure in the vessel 11 and chamber 4 consequent upon excessive pressure in the system will be relieved therethrough to permit additional opening of the relief valve. A washer 7 is provided on the plunger 2 of the relief valve to dampen the closing movement of this valve.

Title: Improvements in and relating to the wet separation or classification of solid materials
IPC: B03B5/50
Filed: 1940-10-30
Abstract: 547,096. Wet separating. DORR CO., Inc. Oct. 30, 1940, No. 15875. Convention date, Nov. 7, 1939, [Class 82 (ii)] In the wet separation or classification of solid materials, a stream of liquid containing suspended solids is provided having an horizontal and unobstructed upper surface and in communication with an underlying and substantially static body of liquid, the stream being controlled to cause selected solids to pass downwardly into the underlying body of liquid from which they are removed. The stream flows through a zone or pool of progressively increasing depth controlled by an overflow weir located below the communication with the underlying body of liquid. The upper part of the lower end of a classifying tank 7 provided with reciprocating means such as rakes 8 to remove material therein upwardly is covered by a sloping roof 13 divided into sections 13a, 13b by a transverse slot 26 bounded by a depending lip 38 and a baffle 15 on which is adjustably mounted a partition 41 having an overhanging lip 41A forming a weir. The side walls 16 and an end wall 18 mounted on the tank 7 form with the deck 13 a trough within the upper part of which is fitted, and adjustably mounted therein, a U-shaped trough 35 having an end wall which forms with the well 18 a feed section or trough 17. The lower end of the wall 21 terminates a short distance from the part 13b to form a transverse slot 22 the size of which is adjustable by a gate adjustably mounted on the wall 21, and the base 27 of the trough is provided with an upstanding baffle 37. The upper portion of the sides of the tank 7 extend higher than that of the upper sides of the trough so that a higher liquid level is maintained therein than in the pool in the zone 28 formed between the wall 21 and the weir 41A. In operation, the solids in suspension are fed into the feed section 17 and flow through the opening 22 in a relatively thin sheet, over the baffle 37 and down through the slot 26 into the tank 7. As no opening is provided in the tank, the suspension fills up the latter and forms a pool in the zone 28 bounded by the weir 41A. Further supply of suspension causes the latter to overflow over the weir, only the largest particles passing through the slot 26 into the tank below. The rest of the solids in the suspension pass over the weir 41A and are discharged over a lip 14 at the end of the section 13a. Additional water from a pipe 42 may be supplied to the tank 7 and, as there is no outlet from the latter, causes an upward current of water through the opening 26, thus carrying therewith any small or intermediate-sized particles that have passed through the slot.

Filed: 1969-03-26
Abstract: 1294323 Casting-machines; forging screw-threads UNITED KINGDOM ATOMIC ENERGY AUTHORITY 12 March 1970 [26 March 1969] 15958/69 Headings B3F and B3H A method of casting teeth, ribs or screwthreads on a member or on or in a sleeve 17 comprises rotating a core 18 bodily i.e. without any rotation thereof about its own axis, in a locus about the axis A of the sleeve 17, and pouring molten metal between the core 18 and sleeve 17, the movement of the core not being stopped until the casting metal has solidified and hardened. The sleeve 17 is heated by an induction coil 23 and may have longitudinal grooves on its inner surface to produce keying between the cast annulus and the sleeve. After casting is complete, the table 12 and thus the core 18 are lowered by means of a spindle 13 whose thread is such that the lowering also serves to screw the core 18 off the helical teeth produced by the casting. The table 12 is supported on a flange 16 by resilient members 27 which allow slight lateral movements of the table to permit accurate positioning of the core 18 with respect to the casting before lowering of the table is begun. The rotating movement of the core 18 is effected by arms 21, 22 releasably attached to the top of the core and to eccentrics 6, 7 mounted on rotatable spindles 2, 3. The rotating movement serves to swage the tooth tips so that no final machining of the cast article is necessary. Improved swaging is obtained by slightly increasing the common throw of the eccentrics during cooling of the metal through the plastic state.
