Title: Improvements in or relating to control of transistor oscillators
IPC: H03C3/00
Filed: 1960-05-20
Abstract: 954,053. Frequency modulation; transistor oscillator circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 20, 1960 [May 23, 1959], No. 17862/60. Headings H3R and H3T. In a transistor sine-wave oscillator the oscillation generated renders the transistor conductive only during part of the oscillation period and is of amplitude then so high that the collector current reverses during part of this period for a variable duration determined by controlling the emitter/base voltage, so varying the oscillation frequency introducing capacitor 11 in the tuned circuit. The resulting collector/base rectification produces limiting, and limiting of excursions of opposite polarity may be effected by a rectifier 20. The frequency varies inversely with increase of forward bias of the emitter, but frequency and amplitude are both independent largely of transistor characteristics and temperature. The capacitor 3 earths the base for radio frequencies. The inductance 12 and capacitor 11 may be dispensed with and the supply voltage fed through inductance 9.

Title: Improvements in and relating to the treatment of heavy hydrocarbons
IPC: C10G9/42
Filed: 1942-12-16
Abstract: Resinous products are obtained by subjecting the liquid distillates produced by the processes described in Specifications 566,281, 566,282, [both in Group III], 567,420 and 573,240 to a further heat treatment within the temperature range of 400-500 DEG  C., the resulting products being subjected to fractionation and/or solvent extraction to isolate different resins and hydrocarbon fractions.  In examples: (1) a heavy distillate of boiling range 200-395 DEG  C. obtained by the conversion of cracked residue by dripping the latter on to coke lumps heated to 440 DEG  C., was treated with furfural to separate (a) paraffinic and (b) non-paraffinic constituents.  The paraffinic portion (a) was distilled to leave a petroleum jelly which was then heated for 4 hours on a molten metal bath at 400-480 DEG  C. The distillate obtained was treated with furfural and on distilling off the furfural, a resin having a m.p. of 45 DEG  C. was obtained. The non-paraffinic portion (b) was also distilled to give gas oil and lubricating fractions and leave a resinous residue which was treated with petrol ether to separate two resins, (1) a resin insoluble in petrol ether but soluble in toluene, and (2) a resin soluble in the ether.

Title: Improvements in and relating to fuel oils
Inventor: GRAHAM ROBERT
IPC: C10L1/12
Filed: 1951-07-30
Abstract: A fuel oil composition which, on combustion in a furnace or internal combustion power plant, yields an ash which has a high melting point and thus does not adhere to or corrode the surfaces of the furnace or power plant, comprises a high ash residual fuel oil and a minor proportion of an oil-soluble organic compound of phosphorus.  The high ash residual fuel oil is a liquid fuel having an ash content of at least 0.005 per cent when measured by method I.P.-4/44 of the Institute of Petroleum, having a viscosity of at least 100 seconds Redwood I at 100 DEG F and consisting of or containing a residual petroleum oil; in addition to residual petroleum oil, the high ash residual fuel oil may contain other liquid fuels such as distilled or cracked hydrocarbon fuel oils.  In particular, the high ash residual fuel oil may be one which, on combustion, forms an ash containing a high proportion of vanadium and/or sodium compounds.  The oil-soluble phosphorus compound may be added to the high ash residual fuel in bulk or it may be injected, either as such or as a solution in a suitable solvent, into the fuel oil supply lines to the burner or burners of a furnace or internal combustion power plant at a point before the burner or burners.  Types of phosphorus compounds mentioned are (1) organic esters of oxyacids of phosphorus, such as the alkyl, aryl, alkaryl, aralkyl or cycloalkyl esters of the phosphoric or phosphorus acids, (2) organic derivatives of hydrides of phosphorus, such as the alkyl, aryl, alkaryl, aralkyl or cycloalkyl phosphines, (3) the phosphonium bases or salts thereof, (4) the alkyl, aryl, alkaryl, aralkyl or cycloalkyl phosphonic or phosphinic acids and salts or p  esters thereof and (5) the alkyl, aryl, alkaryl, aralkyl or cycloalkyl phosphine oxides.

Title: Improvements in and relating to fuel injection systems for reversible internal combustion engines
IPC: F01L13/00
Filed: 1946-06-17
Abstract: 613,561. Reversing. WIENE, P. E. June 17, 1946, No. 18091. Convention date, June 16, 1945. [Class 7 (v)] In a reversible multi-cylinder engine, in which control valves put individual fuel pumps for each cylinder in communication with different cylinder injectors for each direction of rotation, provision is made for moving the control valve in another sense to prevent sticking. As shown in Fig. 10, a control valve G1 for a three-cylinder engine is turned through an angle of 90 degrees by a lever X when reversing and oscillated by an eccentric V to prevent sticking. For ahead working, fuel is fed through a recess D and passage c1 to the injector on a cylinder C1, not shown. On reversing, the fuel is fed through the recess D and a passage g2 to the control valve of cylinder C2 and at the same time fuel from the pump of cylinder C3 flows by a passage g3 and a groove F to the passage c1 leading to the injector on cylinder C1. The passages, recesses and grooves may be duplicated to balance the valve, and drainage grooves E may be provided. In a modification, the valve is moved longitudinally for reversing and oscillated to prevent sticking. Figs. 13, 17 show an arrangement in which the control valve is incorporated in the fuel pump plunger shown shaded in the development view, Fig. 17, S being the suction orifices. For running ahead, the orifices S are placed on lines 20, 20, 21 and the fuel is pumped to the injector of cylinder C1 through passages c1a during the part of the stroke when the orifices S are cut off. For reversing, the orifices S are placed on lines 22, 23, 24 and fuel is pumped through passages c2 to the plunger of the pump on cylinder c2, whereas fuel coming from the plunger of the pump on cylinder c3 is delivered through passages a3, recesses F, connected by a passage C1b to the injector of cylinder 1. In a modification, the height is reduced by staggering the recesses F, but the valve is not balanced by duplication of the passages as shown in Figs. 13 and 17. Specification 611,423 is referred to.

Title: Improvements in blowpipe apparatus for cutting metals
IPC: B23K7/00
Filed: 1920-07-02
Abstract: 146,390. Davis-Bournonville Co., (Assignees of Plumley, S.). Jan. 13, 1919, [Convention date]. Dividing by fusion,-In a blow-pipe apparatus for cutting metals of the type in which the blowpipe is mounted in a universally movable frame moved according to pattern by a mechanically driven tracer roller, the track roller is mounted on an axis perpendicular to the plane of movement, and is - so arranged as to adhere to the edge of the pattern. In the form shown in Fig. 1, the blow-pipe 10 and the tracer carrier 13 are respectively mounted in the arms 7, 8 of a pantograph frame. A milled tracer roller 29, Fig. 2, is formed in the reduced end of a shaft 25 which is rotated by reducing-gear 23, 22, 20, 19 from a shaft 15 rotated by worm gear 16, 17 from an electric motor 12 carried by the arm 8. The speed may be varied by a rheostat motor controller. In order that the roller may adhere to the pattern a, it forms one pole of an electro-magnet, the other pole 30 of which is at the lower end of a shell 32 encircling the energizing coil 34 and turning in a bearing 27. The terminals of the coil are connected with insulated conductor rings 35, 36 in contact with brush terminals 37, 38 in circuit with the motor and a battery, a switch being mounted on the torch bracket so as to control the motor and also the magnetization of the tracer. The switch may also be connected mechanically with the cutting oxygen valve. The roller is also stated to be further caused to adhere to the pattern by the friction between the top surface of the pattern and the bottom of the pole 30, non-magnetic spacer 50 and shoulder 33 on the shaft 25. If desired, this frictional contact with the top of the patterns may be dispensed with by the use of a roller-bearing foot on the bottom of the tracer bracket 28, or alternatively a magnetic tracer may be dispensed with, in which case it is stated that the roller is caused to adhere to the pattern by friction between the top surface of the pattern and the shoulder 33 on the shaft 25. In another modification, a bar magnet tracer shaft is used, the conductor rings being placed on the top and bottom disks of a short surrounding coil, and the shoulder on the tracer shaft may either be in contact with the top of the pattern or raised clear of it as in the previous form.

Filed: 1916-12-29
Abstract: 126,345. Mansell, J. H., and Redpath, R. Dec. 29, 1916. Machine guns.-Consists in providing within an axially sliding breech block 3 a sleeve 5 which encloses the striker 6 and its spring 7, and which is capable of limited axial movement to operate a transverse sliding locking-block 4. The recoil compresses a spring 12 around the barrel 1, and also a spring 21 in a cylinder 15 beneath the barrel. At the end of the recoil, the sleeve is held back by a toe 24 which engages a lug 20 depending from the sleeve. 'During the run out of the barrel by its spring 12, the sleeve wedges the locking block aside and opens the breech, the spent cartridge being at the same time extracted by a pivoted hook 27 and ejected through an aperture 30 on the right. At the end of the run out, the too 24 is tripped by the engagement of an incline 36 carried by the barrel with another toe 37 at the front end of the longitudinal rocking shaft 23 which has the toe 24 at its rear end. The breech is then closed by the spring 21, a fresh cartridge being simultaneously fed by the mechanism described in Specification 126,346. At the same time also, the striker is cocked by a sear 55 controlled by a trigger through a wire 56, or by an automatic sear 54 which is tripped at the last moment by a toe 57 on the sleeve coming against a lug 58 on the sear. The striker may be recocked by hand by a lever 61 without opening the breech. The breech may be opened by hand by disconnecting the lug 20 of the sleeve from the rod 18 of the spring 21, the handle 59 on the lug 20 being made for this purpose like a pair of pincers which grips a groove in the rod 18 except when grasped by the hand.

Abstract: 1355355 Decoding HONEYWELL INFORMATION SYSTEMS Inc 2 June 1971 [2 July 1970] 18649/71 Heading G4C In a system for decoding data recorded by flux transitions in cells on a magnetic medium, e.g. a disc 10 (Fig. 1), square wave output signals from a comparator 32 detecting the polarity of the signal read from the medium after it has been differentiated are applied to integrators 48, 49 which operate during the first and second halves of a bit cell time respectively, to set or reset bi-stables 60, 61 in dependence on the polarity of the integrated outputs, and thus control via logic circuitry comprising gates 68, 70, 72 and an inverter 65, the generation of the decoded binary data by a bi-stable 62. As described clocking signals for the bi-stables 60, 61, 62 and FET switches 50, 52 controlling the integrators 48, 49 are derived from the output of comparator 32 via a pulse processor 34, phase detector 40, voltage controlled oscillator 42 and bi-stable 44. For double frequency coded data the logic circuitry comprises an equivalence gate so that if, for example, the output of integrator 48 at the end of the first half of a bit cell is the same as the output of integrator 49 at the end of the second half of the same cell bi-stables 60, 61 are both set and consequently bi-stable 62 is triggered to its reset state to indicate a recorded bit of " zero ". By operating the integrator over a half bit cell time errors due to for example noise are illuminated. The logic may be modified to decode phase modulated coded signals.
