Title: Improvements in or relating to a steam generating power plant and method of producing steam
IPC: F22G5/00
Filed: 1953-09-23
Abstract: 731,338. Steam superheaters; water-tube steam boilers. COMBUSTION ENGINEERING, Inc. Sept. 23, 1953 [Oct. 9, 1952], No. 26210/53. Classes 123 (2) and 123 (3). The steam generator of a steam power plant operating with a reheat cycle has a vertical furnace chamber A fired by corner-mounted, tilting burners 21 the combustion gases from which leave the furnace through a lateral pass D locating successively the high temperature section 22 of a superheater and the tube banks 24, 26 of a reheater and then flow downwardly through a pass E in which is positioned the tube banks 28, 29, 30 of the low temperature section of the superheater and an economizer 32. The furnace A and lateral pass D are lined with steam generating tubes extending from lower headers 6, 17, 18 to a steam and water drum 11. The steam from the drum passes to a header 48 and thence through tubes 49, 52 lining downpass E into headers 51L, 51R from which it passes through superheater banks 30, 39, 28 to a header 56. From this header the steam flows through a pipe 58 wherein its temperature is adjusted by an attemperator spray 62, the steam then passing successively through a heatexchanger H in indirect contact with steam to be reheated and through superheater 22 to the high pressure stage of a turbine 80. A second attemperating spray 75 is provided in the pipe 74 leading from the heat exchanger to super heater 22 to regulate the final temperature of superheat. Steam to be reheated passes from the turbine through pipe 84, through the heat exchanger H and reheater 24, 26 and returns to the low pressure stage of the turbine through pipe 90. As shown in Fig. 2, the heat exchanger H consists of a row of pendent U-tubes 64 each mounted axially within a larger diameter U- tube 68. The temperature of superheat and of reheat is controlled overall for any given combustion rate by adjusting the tilt of burners 21, control by gas. recirculation and gas by-passing being used in conjunction with this tilting burner control if desired. Individual control of superheat temperature is obtained by regulating the water supply to spray 75 whilst for individual control of reheat temperature the water supply to spray 62 is regulated manually or automatically to control the temperature of the partially superheated steam entering the heat exchanger H and thus indirectly to control the reheat temperature. Spray desuperheating of the steam to be reheated is thus eliminated and the load range over which the superheat and reheat temperatures can be held constant is considerably extended.

Title: Improvements in or relating to the production of optical lenses and other devices having an optically accurate finish
IPC: B29C43/00
Filed: 1945-10-12
Abstract: 602,126. Moulding lenses &c. from plastic materials. JOHNSON, J., and COMBINED OPTICAL INDUSTRIES, Ltd. Oct. 12, 1945, No. 26747. [Class 87(ii)] An article having an optically accurate finish is moulded by laying a preformed blank 12 of thermoplastic material on a metallic die 13, applying a high-frequency electric current to an upper metallic die 14 to heat the blank and, when the blank reaches moulding temperature, switching the current off and raising a press platen 20 to apply the moulding pressure to the blank. The blank is cooled during moulding by the dies which are relatively cold due to their high thermal capacity and the fact that very little heat is generated in them by the high frequency current. The dies may be positively cooled by making them hollow and passing water through them or by supporting them in hollow sockets which receive cooling water, in which case the dies are electrically insulated from the sockets by a good conductor of heat such as mica. The cooling arrangement described in Specification 572,748 may be used. The upper die 14 is screwed into a metallic socket 15 which is rigidly secured to the upper platen 17 of the press. A block 16 of insulating material is positioned between the socket and the platen. The lower die 13 is slidably mounted in a surround 18. A helical spring 21 is situated beneath the die to restrain the downward movement of the die and to facilitate removal of the moulded article by raising the die when the platen 20 is lowered. The lower platen is earthed. One or both of the dies may be mounted in surrounds of insulating material such as glass or porcelain. The blank may be prepared by mechanical operations as described in Specification 556,743. The general arrangement of the moulding press may be that illustrated in Specification 556,743 or Specification 572,748. Specification 585,580 also is referred to.

Filed: 1942-10-20
Abstract: 580,959. Telecontrol of temperatureregulating installations. LANDIS & GYR SOC. ANON. Oct. 20, 1942, No. 26777/45. Convention date, Nov. 24, 1941. Divided out of 577,744. [Class 40 (i)] In a system for selectively controlling the current in the auxiliary heaters of a number of thermostats, the necessary signal is sent by means of two impulses sent at characteristic points in the cycle of synchronous switches at the sending and receiving stations, the signal being registered on relays and causing the control of a regulating resistance by a local follow-up system. Thermostat selection is effected by keys R and temperature controls by keys T, the control relays, other than line relay ER and busy relay ZR, have operating and releasing windings and the armatures remain in the last set position. When a key R, T of each group is actuated, corresponding contacts r, t of distributer S1 are marked, motor M1 is started'and maintained for one revolution over off-normal contact S1<11> and line relay ER receives an impulse from S1(0). Relay ER starts motor M2 of the receiving distributer S2 maintained over S2<11> and providing a momentary impulse over S2<1> which restores relays ER1, ER2, ET, which were left operated after the preceding adjustment. As the distributers rotate, the thermostat selecting relay ER1 or ER2 is operated, together with a temperature control relay ET to marka contact t in one or other of the control switches L1, L2 over which motor MR1 or 2 is started to adjust the resistance Wl or 2 and the switch L1 or 2 which opens the motor circuit when the gap in the ring reaches the marked contact. When the transmitter distributer approaches normal contact S1<1>, energizes the restoring windings of the transmitting relays. The keys are rendered ineffective, once a selection has been made, by relay ZR which also lights an engaged lamp BL, the relay ZR being held over an off-normal contact of S1 and being sluggish enough to hold on until W1 and W2 has been set.

Title: A process for the production of aromatic hydrocarbons from unsaturated hydrocarbons
IPC: C07C15/00
Filed: 1939-09-28
Abstract: 536,491. Hydrocarbons. FIFE, J. G. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). Sept. 28, 1939, No. 26797. [Class 2 (iii)] In a process for the production of aromatic hydrocarbons from unsaturated hydrocarbons, the latter are first freed from peroxides, and then subjected to catalytic cyclization. As initial materials, hexene-1, heptene-1 and -2, and 2-methyloctene are specified ; also mixtures consisting of or containing olefines, obtainable by vapour phase cracking of hydrocarbon materials containing solid paraffin wax. The initial material may be freed from peroxides by treatment with a reducing agent, e.g. acidified ferrous sulphate or sodium bisulphite, or by distillation or extraction. Oxides of metals of the sixth group of the periodic system, e.g. chromium oxide, may be used as catalysts alone or in admixture with oxides of the third or fourth group. The process may also be carried out in the presence of activators, e.g. potassium hydroxide. The presence of hydrogen prolongs the life of the catalyst. In examples, benzene and xylene are obtained from hexene-1 and octene-2 using a chromium oxide catalyst, the starting material being freed from peroxide by treatment with ferrous sylphate acidified with sulphuric acid. The results obtained are contrasted with those obtained without the preliminary purification from peroxides.

Title: Improvements in or relating to automatic self-regulating swash-plate pumps
IPC: F04B49/24
Filed: 1956-09-04
Abstract: 842,361. Swash-plate pumps. RECHERCHES ETUDES PRODUCTION R. E. P. Sept. 4, 1956 [Sept. 5, 1955], No. 27062/56. Class 102(1). A swash-plate pump, of the type described in Specification 842,360, comprises pistons 9, Fig. 1, reciprocating in cylinders 7, each cylinder being provided with inlet ports 8 and an outlet valve 10 whereby liquid is delivered through conduits 11 to a chamber 12 and the pump outlet 6. Each cylinder is surrounded by a sleeve 33 which is movable axially by a spider member 31 in accordance with the delivery pressure in the chamber 12 acting on a piston member 29. Each cylinder 7 is provided with at least one set of ports 34, Fig. 2, arranged on a spiral while the sleeve 33 is provided with a helical groove 35, for each set of ports 34, the pitch of which is close to that of the ports, the arrangement being such that at a low delivery pressure of the pump the groove 35 does not communicate with the ports 34 but as the delivery pressure increases the sleeves 33 are moved axially and the groove 35 registers successively with each of the ports 34, thus at a predetermined pressure the groove 35 is in communication with all the posts 34. Such an arrangement provides a regulation of the pump delivery in that the pistons 9 are provided with an axial bore communicating with a groove 37 which successively register with the ports 34 during the delivery stroke, thus as the sleeve 33 moves to register the groove 35 and the ports 34 part of the liquid in cylinder 7 is by-passed during the delivery stroke, the groove 35 being open by ports to the pump inlet. When the delivery pressure is such that the sleeves 35 are moved to by-pass the whole of the liquid in the cylinders a small amount of liquid is still required to be pumped to allow for leakages, thus delivery is achieved by one pump piston 9S, shown in the lower half of Fig. 2. The piston 9S is provided with a groove 37S, which is narrower than the groove 37 of the remaining pistons, and the cylinder housing this piston is provided with an extra port 34 offset from the spiral and this provides for wire-drawing, which would normally occur on the last port 34 of each cylinder, to be confined to a single cylinder. Reference has been directed by the Comptroller to Specification 738,906.

Abstract: 1372479 Cable burying - trenching apparatus FURUKAWA DENKI KOGYO KK 9 June 1972 [15 Nov 1971 (2) 8 May 1972] 27158/72 Heading E1F [Also in Division H2] A plough-type cable-burying device 1 intended for use in submarine cable laying comprises a steel tubular body 11 which guides the cable 4 into the trench (6) (see Fig. 1). Sledges 13 are secured to the body 11 by brackets 12, and are adapted to remain in constant contact with the ground to stabilize the device 1, the rear lower portion of which comprises a protective blade 15, four cultivating blades 16, 16' which initiate the cut in the trench (6), and a plough-type digging blade 14 having a front digging portion with a sharp knife edge 14a and a soil expelling portion 14b. The cable first passes through cable guide cylinders 18, which are fitted with guide brackets 20 for towing wires 3 which are secured to metal fittings 17. In a further embodiment, Fig. 7, horizontal base plates 23 are secured on each side of the tubular body 11, and support pneumatic cylinders 24 extending through the plates 23 and provided at their lower ends with stabilizing sledges 13. Gas under pressure is fed under remote control from gas reservoirs 31 to the cylinders 24 to select the cutting depth of the device or to pull the blades clear of the ground. The digging element 14a is separated from element 14b and pivoted on pin 32 on a centre plate 33 on the lower side of the body 11. A remote controlled motor 35 drives a crank mechanism 34 which causes the element 14a to oscillate back and forwards and thus reduces the dragging force. In order to maintain the attitude of the cutting device such that the minimum strain is put on the cable 4, the dimensions are chosen such that the turning moment M Fig. 9 (not shown) is in the correct direction, or as in Fig. 8 (not shown) a lead weight is provided within the cavity (40) of the hollow expelling element 14b.

Title: Improvements in or relating to continuous brewing processes
Inventor: LEAVERS DONALD GIPSON
IPC: C12C7/20
Filed: 1963-07-10
Abstract: In the continuous heat treatment and hopping of brewers' wort, in which a slurry of hops in wort is formed and fed in continuous flow to a boiling vessel and boiled therein by the heat from either injection of steam or an indirect heating surface, the hops are maintained in suspension without mechanical agitation by means of turbulence arising from either the steam injection or from ebullition (as the case may be) and from recirculation of the wort and hops through the vessel.  Prior to the formation of the hop-wort slurry, the wort is pre-heated e.g. to 180 DEG F., or pre-boiled by direct injection of steam or indirect heat exchange with steam.  A proportion of the hops may be added before the pre-boiling.  The level of wort or slurry in the pre-boiling and boiling vessels is controlled by a weir.  The heat-treated and hopped wort is filtered. The hop-wort slurry may be prepared by entraining hops into wort swirling around the wall of a mixing vessel, the rate of withdrawal from the vessel of the resultant slurry being such that there is no static level of liquid in the vessel, or by mixing hops and wort in a small agitated vessel. According to the disclosures of the examples, pressures of 10 and 15 inches water gauge were maintained in the boiling vessel and a steam supply was either injected at a gauge pressure of between 20 and 30 lbs. per sq. inch or passed through an indirect heat-exchanger to provide an evaporation rate of 6% per hour.
