IPC: A21C9/08
Filed: 1952-11-05
Abstract: 744,366. Bread-making. BAKER PERKINS, Ltd. Nov. 5, 1953 [Nov. 5, 1952], No. 27827/52. Class 87 (2). A bread tin 21 is tilted about one of its ends and a plurality of dough pieces (as shown, four) are fed in succession and in parallelism to the same point at the upper end of the tin. Each dough piece except the last (i.e., as shown, the first three) rolls down the inclined bottom of the tin and the pieces lie one behind another, but the last one lies where it falls. As shown the tins are supported by an inclined conveyer 19 but may alternatively be pushed along inclined rails. The conveyer 19 is continuously driven, the tins being arrested thereon by stop means (not shown) actuated by counting means 22 which operate on completion of a count of four dough pieces. The four pieces are formed from an initial piece 1 which, after elongation between a plate 4 and a conveyer 2, is cut into four by rotary knives 6. The four cut pieces fall onto a transversely-moving conveyer 10 which delivers them one after another to a conveyer 11, the pieces being steadied by counterweighted tiltable flaps 12 and being delivered between fixed guides 13. Conveyer 11 takes the pieces under a moulding plate 14 whence they fall into the tin. The plate 14 has a dough-piece-restraining flap 18 which may be replaced by a roller.

IPC: F01D3/00
Filed: 1948-10-28
Abstract: 658,778. Gas turbine or jet propulsion plant; centrifugal and screw pumps. ROLLSROYCE, Ltd. Oct. 28, 1948. [Classes 110(i) and 110(iii)] [Also in Groups XXIV and XXXIII] In a gas turbine power plant, the axial thrust generated in a rotor is balanced by that produced in a shaft-coupling having helical splines. The two stages of a centrifugal compressor may be joined by the coupling and the axial thrust of one stage is transmitted by it to the shaft of the other, stage. If the axial thrusts of the stages are in opposition the thrusts are balanced or the overall thrust which is met by a thrust bearing is reduced. If the axial thrusts are in one, direction, the total thrust is taken by a single thrust bearing. The compressor and turbine shafts of a jet-propulsion gas turbine may be joined by the coupling to eliminate or reduce the overall thrust. The coupling may be applied to each rotor set in a gas turbine plant in which two turbine stages separately drive two axial-flow compressor stages. The coupling may be applied to the drive of a marine propeller. Fig. 5 shows a gas turbine plant for driving an airscrew shaft 182. The turbine shaft 155 and high-pressure compressor shaft 160 are coupled by helical splines on a shaft end 161 and a sleeve 156. The sleeve 156 has axial spline engagement with the shaft 155. The shaft 160 is coupled to the lowpressure stage rotor by a helical spline coupling 165. The reduction gear between the turbine set and the shaft 182 comprises a lay shaft 174 with helical toothed wheels 178. 179. The wheel 178 meshes with a pinion on a high-speed shaft 170 with a helical spline coupling 169. The wheel 179 meshes with an internally toothed ring 181.

Title: Catalytic hydrocracking
IPC: F02B3/06
Filed: 1959-08-18
Abstract: A catalyst characterized by hydrocracking activity comprises 15-40% wt. SiO2, 1-8% wt. CoO and 3-20% wt. MoO3, the remainder being Al2O3; it is preferably prepared by admixing mechanically the SiO2 and Al2O3 components, either the mixture or the Al2O3 prior to admixture being impregnated with CoO and MoO3.  Preferred surface area characteristics of the catalyst and its Al2O3 component are given. Specified Co and Mo ingredient precursors are cobalt-ammonium chloride, nitrate and sulphate and cobalt nitrate, fluoride, chloride, bromide, chlorate and bromate; molybdenum oxydibromide, oxydichloride, oxytetrafluoride, tetrabromide and tetrachloride, as well as ammonium molybdate.  The foregoing catalyst is used for hydrocracking hydrocarbons (including mixtures), particularly of initial boiling point at least about 400 DEG F., a 50% point of at least about 500 DEG F. and an end boiling point of at least about 600 DEG F. and boiling substantially continuously between the said initial and end boiling-points, said fractions including gas oils, residual stocks, cycle stocks, whole topped crudes and heavy hydrocarbon fractions obtained by destructive hydrogenation of coal, tars, pitches and asphalts.  The hydrocracking process is effected between 600 and 950 DEG F. at a LHSV between 0.1 and 10 and a hydrogen partial pressure between 700 and 3000 p.s.i.g., employing a molar ratio of hydrogen to hydrocarbon between 2 and 80.  It may be carried out batchwise, but preferably continuously, e.g. in a fixed or moving (cocurrent or countercurrent flow) bed or fluid operation. In examples, a 650-920 DEG F.  Guico gas oil and a 650-800 DEG F. West Texas gas oil are hydrocracked, the products being analysed in terms of dry gas (including propane), C4's, C5's, heavy naphtha, fuel oil and cycle stock; the heavy naphtha was further analysed in terms of per cent paraffins, naphthenes, aromatics and olefins, the fuel oil and cycle stock in terms of diesel index, and the fuel oil also in terms of per cent aromatics and olefins. Specification 576,058 is referred to.

Title: Vacuum deposition of ferromagnetic metal films
IPC: H01F41/20
Filed: 1965-07-06
Abstract: <PICT:1104708/C6-C7/1> A ferromagnetic metal is vacuum evaporated, directed and condensed on a substrate surface at an angle of incidence of greater than 45 degrees and thereafter cooled to room temperature, the evaporated metal being deposited on the substrate in a series of bursts.  The angle of incidence is the angle the stream of vapourized metal makes with the normal to the substrate.  By the process magnetic films having coercivities greater than 100 oersteds can be produced and a film can be arranged to have a chosen coercivity over a range. The ferromagnetic metal may consist of Co, Fe, Ni, a Co-Fe alloy, a Co-Ni alloy or a Ni-Fe alloy containing between 1 and 74 or 86 and 99% by weight Ni and the balance Fe. Sulphur (e.g. 0.5 to 4% by weight) may be incorporated in the metal by simultaneous evaporation so as to modify the metals magnetic properties.  The substrate may be a tape loop drum or disc, e.g. of polyethylene terephthalate.  The thickness of the deposited metal film may be less than 5000 Angstroms. Fig. 1 shows a vacuum chamber 10, e.g. at 2 x 10-5 mm. Hg.  A vessel 32 contains ferromagnetic material heated by an induction coil 58 which is supplied with modulated current to provide bursts of evaporated metal each of 5 to 10 seconds duration.  The evaporated metal may be deposited on tape 30 as it is wound between reels 34.  The angle of incidence of the metal on the tape and the distance of the tape from the metal source can be adjusted at 54.  A shield 60 limits the area of tape exposed to volatilized metal.  A Cu cooling coil is provided at 64.  The tape reels can be driven in either direction so that tape can be coated with several layers without interrupting the vacuum.  Resistance heating may be used instead of induction heating.  After coating, a sample may be allowed to cool to 50 or 60 DEG C. before air is allowed into the chamber.  Reference is made to two step vacuum deposition with an intermediate air cooling step as disclosed in Specification 1,104,709.

Abstract: 855,969. Transistors. PYE Ltd. Sept. 3, 1958 [Sept. 10, 1957], No. 28535/57. Class 37 A transistor comprises a semiconductor wafer, the opposite surface regions of which have different conductivity characteristics, with a base electrode on each main surface, the base electrodes being so arranged that when a voltage is applied between them they provide a field parallel to the emitter-collector current path. In the embodiment which is a PNIP type transistor the base electrodes 1, 2 are annular and surround the emitter and collector zones E, C respectively. When a voltage 3 is applied between them of the polarity shown holes are repelled from the annular intrinsic zone beneath electrode 2 and therefore focused towards the collector zone. The amplification factor of the transistor may thus be varied by means of an adjustable resistor R or by application of a modulating signal voltage across this resistor. The invention is also applicable to NPIN transistors and drift transistors.
