Title: Improvements in or relating to the valve mechanisms of hydraulically operated jaw crushers
IPC: B02C1/00
Filed: 1960-04-01
Abstract: 894,023. Jaw crushers. GAULDIE, K. March 30, 1961 [April 1, 1960], No. 11639/60. Class 59. [Also in Group XXIX] A valve mechanism for a hydraulicallyoperated jaw crusher having a plunger 1 reciprocated in a cylinder 3 comprises a valve 9 which is rotatably mounted in a cylinder 9a and has a pair of ports 12 of like size and located diametrically opposite each other whereby during alternate complete to-and-fro movements the valve hydraulically connects the plunger by the ports, to a ram cylinder 7 and during intervening complete to-and-fro movements connects it elsewhere. The cylinder 3 in which the plunger reciprocates is mounted on trunnions 4, 5, so as to oscillate as the plunger is reciprocated by a crank 6 on a shaft 2. The trunnions form the valve cylinder 9a in which the valve 9 is rotated by a chain drive 10 at a quarter of the speed of the shaft 2, and during the alternate complete to-and-fro movements, the fluid displaced by the plunger passes through ports 11 and the ports 12 which are in communication with passages 14, 18 in the valve cylinder 9a, a recess 19 and a passage 16 leading to the ram cylinder 7 of the jaw crusher. During the intervening to-and-fro movements of the plunger, the rotation of the ram closes the communication between the ports 12 and passages 14, 18, and diametrically-opposed ports 13 communicate with passages 15, 20 in the valve cylinder 9a and a recess 21 and passage 17 leading to a fluid-receiving air chamber 8 or a second ram cylinder. In an alternative embodiment, the valve 9 is oscillated by a crank driven from the shaft 2. Specifications 642,315 and 839,091 are referred to.

Abstract: 590,323. Feeding closure caps. KRUEGER, E. A. July 19, 1943, No. 11724. [Class 125 (ii)] [Also in Groups II and XXX] Articles such as closure caps for bottles, jars &c. are brought from random orientation into ordered sequence and loaded into a hopper 32, Figs. 1 and 4, by way of the lid 33, the hopper being rotated around shaft 25 by means of a motor 18, and flights 48 causing the articles to be guided on to a back plate 29 in such a way that they slide downwards and become located between plate 29 and gauge ring 37, whereafter they pass into chute 50 in single file. Articles jammed between plates 29, 37 are freed by lifting gauge plate 37 by a cam-actuated lever 39, Fig. 4. The articles in chute 50, some of which are wrong side up, are checked momentarily by escapement detent 86, Fig. 7, whereafter they fall into recesses 66b of a star wheel 66, rotated on shaft 62 from motor 18. Those which are right side up are supported on a ledge 68, Fig. 8, the article being shown at C, and are carried round in this position. The others are not thus supported and tilt, under the action of a spring 69, into a recess 67 behind the star wheel as shown in Fig. 9, the recess being shaped as in Fig. 12, so that the article is turned over while being carried round by the star-wheel. The articles are thus delivered at throat 74 into chute 75 in the same sequence that they entered the star-wheel. The articles may be checked momentarily at the entrance to chute 75 by an escapement detent similar to 86, Fig. 7. The escapement mechanism includes a cam 78, Fig. 7, on shaft 62, a roller 80 on a lever 79, a spring 81 and a pawl 84 with upper and lower detents 87, 86 respectively. A modified form of device for turning over articles which are wrong side up is described in which the ledge 68 upon which the articles are supported forms part of a resiliently hinged wall of recess 67. The formation of this recess is otherwise the same as before.

Title: Electro-magnetic circuit breakers
IPC: H01H71/38
Filed: 1925-05-09
Abstract: 253,679. Railing, A. H., and Angold, A. E. May 9, 1925. Automatic circuit-breakers; sparking-preventing. - A direct-current electromagnetic circuitbreaker of the kind comprising a magnet for holding the contacts closed, a blow-out device with a magnetic circuit including magnetic material and a load winding which opens the breaker under the influence of load current and is connected in parallel with an inductive circuit, has the inductive circuit comprising a winding arranged on the magnetic circuit of the blow-out device of the breaker. As applied to a circuitbreaker of the type described in Specification. 252,514, the hold-on coil 2 is energized from a suitable source and normally attracts an armature 3 on a spring-controlled arm 4 carrying a movable contact 5 which engages a contact 6. The hold-on magnet 1 may be solid, but its polepieces and armature are laminated and the former carry load windings 13, 14, in shunt with which are inductive windings 17 comprising a few turns of conductor wound on the blow-out magnet 15 in the same sense as the additional blow-out coils 16, which may be series coils as shown, or shunt coils or voltage coils energized from some suitable source. The current flows through contacts 6, 5, lead 19 and coils 16 and then through windings 13, 14 and 17 in parallel, to the conductor 23. On overload a back E.M.F. is set up in the windings 17, which E.M.F., if small, does not appreciably affect the current distribution between the parallel paths, but if the overload is sudden, as for instance on short-circuit, the large back E.M.F. sends a larger proportion of the current through the windings 13, 14 which overcomes the holding-on action and allows the spring 7 to open the switch. The magnet 15 is laminated so that flux changes respond quickly to current changes, the inductive effect being increased by the coils 16. An adjustable air-gap or magnetic bridge may be used for varying the back E.M.F., or the magnet 15 may have a conducting ring closed on itself or through a resistance, adjustable or otherwise. A switch may be arranged to open the circuit of wings 17 or 13 and 14 when the breaker is being closed.

Abstract: 1,222,186. Removal of hydrocarbons from hydrogen. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 10 March, 1969, No. 12383/69. Heading C1A. [Also in Division C5] The hydrocarbon-containing H 2  stream from the hydroprocessing of a hydrocarbon oil is purified by a process which includes mixing it with the hot reactor gases from the non-catalytic partial combustion, optionally with steam and/ or CO 2  of a mineral oil. Hydroprocessing means hydro-cracking, -finishing, -desulphurization, and hydrogenation, and includes catalytic reforming, and the H 2  stream may be delivered to the partial combustion stage or preferably be mixed with the reactor gases after they have left that stage, e.g. in a carburetter. Partial combustion may be carried out as described in Specification 851,542, the H 2  stream being added to the reactor gases before they enter the waste heat boiler. The mineral oil fraction may be liquid or gaseous and may include the residue from a deasphalting step, in which the deasphalted oil forms the feed to the hydro-process, see Fig. 2 (not shown). The mixed gas may be subjected to conventional CO-conversion and purification steps, and final H 2  recycled to the hydroprocessing stage. In another embodiment, see Fig. 3, the initial H 2  stream 20 comes from a catalytic reformer 19, and the final purified H 2  21 is passed to a catalytic hydrocracker 22 which produces a contaminated H 2  stream 23 which may be sent directly to the partial combustion stage 8 or first mixed with the stream 20.
