IPC: B21D39/06
Filed: 1932-12-30
Abstract: 412,959. Relining bearings, bushes, &c. LUHMANN, K., 1, Seestrasse, and MARTIN, K., 2, Brandenburgerstrasse, both in Kirchm÷ser, Havel, Germany. Dec. 30, 1932, Nos. 36963, 36964, and 36965. Convention dates, Dec. 30, 1931, Feb. 20, 1932, and July 20, 1932. [Classes 83 (i), 83 (ii), and 83 (iv).] Casting ; rolling annular bodies.-Connecting- rod &c. brasses are relined with antifriction metal and bored or rolled to size without resetting the rods in which the brasses are mounted. Connecting-rods 31, 32 with brasses 35, 41, 38 are mounted in a lathe by brackets 33 with the brasses in place. They are end-faced and bored. Each brass in succession is relined from a movable crucible and a rolling &c. tool rotated by a face-plate P rolls the bearings to size. Casting, Fig. 1. The lining metal is melted in a closed crucible 43 on a carriage 44. The core is held between lathe centres 40. A pipe 42 feeds the metal to the mould. A container 45 supplies fuel to the burner which is supplied with preheated air by an air heater connected by a metal flexible tube to the crucible. A container 46 provides compressed air which may be preheated to a pipe 47 for forcing the metal into the mould. A pipe 48 feeds air to the bearing after casting to improve its crystalline structure. Rolling, Fig. 2. The rolling device is mounted between centres 8 and carries rollers 1 in holders 2 in a spider 3. A core 5 axially movable on a spindle 6 adjusts the rollers. Co-operating screwed sleeves 9, 10 are loose on the spindle 6. An adjustable set-screw 16 on a bush 14 attached to the sleeve 9 co-operates with a collar 101 on the sleeve 10 to limit the projection of the rollers. In a modification a single pressure roller 1 is used.

A photographic film base comprising a polymer or copolymer of vinyl chloride vinyl acetate, acrylonitrile or vinylidene chloride or polyethylene terephthalate, or a paper, cloth or fibre sheet impregnated or coated with such a polymer or copolymer, is subbed by coating it with a solution of a vinylidene chloride polymer or copolymer in a mixture of 70-50% by volume of an aromatic hydrocarbon and 30-50% by volume of a ketone, drying in a current of air at 50-85F. and 80 10% relative humidity at an air speed of 0. 5-4 m./sec. to give micro holes over the surface of the layer, and is then coated with a photosensitive layer or a receiving layer containing nuclei for the silver salt diffusion process. The photosensitive layer may be a silver halide emulsion layer. The reverse side of the base may be coated with a hydrophilic anti-curling layer which may contain an antihalation dye. The vinylidene chloride for the subbing layer may be copolymerized with vinyl chloride or acrylonitrile. In Example 2 the reverse side of the film base is coated with an aequous dispersion of a polyvinylidene chloride, a watersoluble colloid and rice starch.

Title: Gas turbine engine fuel control system
IPC: F02C9/32
Filed: 1974-11-06
Abstract: 1492924 Automatic control of gas turbine engines LUCAS INDUSTRIES Ltd 6 Nov 1974 [10 Aug 1973] 37917/73 Heading G3N Stalling of a gas turbine during acceleration is prevented by sensing an engine operating parameter which increases with engine speed but decreases when the engine compressor stalls and using this signal to determine a limit for the amount of fuel supplied to the engine. In the arrangement shown the static pressure head at the compressor outlet P2 is supplied to function generator 11 together with the engine speed N2 (or high-pressure spool speed) and temperature T1 to provide bias and gain control signals which modify a dynamic pressure head signal P2, this being an operating parameter which reduces immediately a stall occurs. This modified signal which represents the allowable maximum acceleration is compared with an actual acceleration signal produced by differentiator 12 in comparator 13 to produce a fuel limit signal for acceleration control. The control logic 15  includes a 'lowest wins' circuit so that the normal control signal can be over-ridden by the limit signal should a stall be sensed.
Patent GB-1196548-A (GB)
Title: Apparatus for Controlling the Operation of a High-Speed Lift
IPC: B66B1/16
Filed: 1968-08-08
Abstract: 1,196,548. Automatic speed control. INVENTIO A.G. Aug. 8, 1968 [Aug. 8, 1967], No.37938/68. Heading G3R. In a control system for a high speed lift, a register SE indicates the next floor at which the lift would be able to stop; the value on this register is compared with a value representing the actual position of the lift and from the difference # a value V m  is continuously generated which represents the maximum speed at which the lift may be travelling in order that it stop at the indicated floor; the value V m  is compared with the actual speed V i  of the lift and when these are equal a calls monitor 39 determines whether there is a call to the indicated floor, in which case an automatic speed control system causes the speed of the lift to decrease according to the value V m , or not, in which case the lift continues and the register SE is advanced to indicate the next floor. The automatic speed control system is employed to cause the lift to follow a predetermined acceleration low diving starting and to maintain a constant running speed. The lift cage CA is driven by a winch motor SM which also drives a tachogenerator T producing the speed signal V i  and a pulse generator disc DP which in conjunction with counter 55 produces a signal α representing the position of the lift. The counter 55 is supplied with pulses Q through a divide by 8 circuit 57; the pulses are also applied direct to a second counter 56 but this is normally held off by a gate 59. When the difference # approaches zero a control circuit 58 opens gate 59 to start counter 56 and closes a gate 60 to stop counter 55. The signals a and # are therefore fixed but a new signal α<SP>1</SP> is generated. The two signals α<SP>1</SP>, 6 are applied to a function generator 37 which produces the value V m , the signal α<SP>1</SP> providing a more precise value V m  as the lift comes to a halt. The lift CA carries sensors DB, DH co-operating with overlapping magnetic plates H<SP>1</SP>, B<SP>1</SP> to generate signals H, B indicating the proximity of the lift to floor level N. When both signals H, B are being generated, i.e. the lift is exactly at the floor N, a signal is applied from a floor generator ME to correct the counter 55 for errors due to slip, &c. at the winch. The Specification describes in detail a binary logic system employing all NOR gates which may employ either semi-conductors or electromagnetic relays Figs. 5-13 (not shown) and also briefly an analogue system performing the same operations Figs. 14- 19 (not shown).

Patent GB-1552949-A (GB)
Title: Isotope separation procesys
IPC: G02B27/00
Filed: 1976-09-15
Abstract: For separating the isotopes of an element, a gaseous compound of this element is simultaneously irradiated by IR radiation of two different wavelengths for a time of less than 10<-5> seconds. In this case, the first radiation has a wavelength which corresponds to an absorption band of the gaseous compound. The absorption band in question must in this case be one which corresponds to a form of molecular vibration in which the atoms of the element to be separated participate. The second radiation has a power density which is higher than 10<6> Watt/cm<2> and has the effect that the compound is isotopically selectively excited and converted. This conversion can either be a decomposition or a reaction with a second gas and the separation or enrichment of the isotopes is carried out by the converted molecules then being separated off from the unconverted molecules and isolated.   As a result of this multiple photon absorption, an additional isotope enrichment is achieved in comparison to hitherto employed processes of single photon absorption.

Filed: 1975-09-18
Abstract: A vegetable or animal oil, fat or mixture thereof is separated into a less saturated liquid and a more saturated solid fraction. The oil or fat is dissolved in 0.5 to 4 times the amount of a C2- to C3-alkanol which contains 2 to 10% water. The solution is cooled below the solution temperature. The upper layer which is formed thereby and contains the suspended crystalline solid fraction is decanted off from the lower layer containing the liquid fraction, and the solvent is removed from both fractions. It is possible in this process to minimise the solvent losses and to keep the crystallisation times short.
