Patent GB-1004660-A (GB)
Title: Production of compounds containing sulfur and nitrogen
Inventor: METZGER HORST
IPC: C08G18/38
Filed: 1964-03-26
Abstract: The invention comprises compounds of the general formula <FORM:1004660/C2/1> in which R is an unsubstituted or halogensubstituted substituted alkyl, aryl (including alkaryl), aralkyl or cycloalkyl radical, R1 and R2 are alkyl radicals and R1 is a hydrogen atom or an amide group of the formula <FORM:1004660/C2/2> the radical R is as defined above and may bear one or two halogen atoms such as Cl or Br atoms.  They may be obtained by reacting an isocyanate of the formula R-N = C = O, or a substance which will form such an isocyanate under the reaction conditions with an oxosulphoniumylide of the formula <FORM:1004660/C2/3> if desired in the presence of an inert solvent, at a temperature of from - 10 DEG C. to 100 DEG  C.  Suitable isocyanates are phenyl, p-tolyl, benzyl, methyl, ethyl, isopropyl, n-butyl, n-octadecyl, cyclohexyl, cyclododecyl, p - chlorophenyl, o-chlorophenyl, 4 - chloro - 3 - methylphenyl, 2-methyl cyclohexyl and b  - chloroethyl isocyanates. The equivalent carbamyl chlorides e.g. those formed by reaction of a primary amine with phosgene, may be used instead of isocyanates. Suitable solvents are for example ethers, hydrocarbons, chlorohydrocarbons, N,N - dialkylsubstituted amides or lower fatty acids, N-alkyllactams or dialkyl sulphoxides.  The products depend on the amounts of reactants used i.e. if an ylide is reacted with an isocyanate in the molar ratio of 0.5: 1 a substituted malonamide is obtained, but if the molar ratio is 1: 1 or an excess of isocyanate is used a mixture of the mono- and di-addition products is formed. The products are useful as intermediates for pharmaceuticals, dyes and pesticides.  Malonic dianilide, p-chloroacetanilide, acetanilide, malonic acid-N,N1-butyldiamide and malonic acid-N,N1-isopropyl-diamide respectively are prepared by catalytic desulphurization with Raney nickel of the appropriate substituted oxosulphurylene amide.

Title: Improvements relating to gas turbine engine fuel systems
Inventor: MORDELL DONALD LOUIS
IPC: F02C7/22
Filed: 1947-05-13
Abstract: 647,342. Gas turbine plant. ROLLS-ROYCE, Ltd. May 13, 1947, No. 12937. [Class 110(iii)] [Also in Group XXIX] A fuel control system for a gas-turbine engine comprises a flow restricting means through which the actual fuel flow to the engine passes, means for varying the flow restricting means solely in accordance with the temperature and pressure of the engine air intake, and pressure sensitive means subject to a pressure drop derived from the flow restricting means and operative to vary the delivery of fuel. As shown the flow restricting means 13 is arranged in a pipe-line 12 delivering fuel from an engine-driven swash-plate pump '7 to the injectors 3 of the engine 1 and comprises two parallel flow paths one through an orifice 15 and the other through two orifices 17, 19. The orifice 15 is varied by a valve 20 actuated by a capsule 21 connected to a thermal bulb exposed in the engine air intake whilst the orifices 17, 19 are differentially controlled by a valve 23 actuated by an evacuated capsule 24 subject to variations in the air intake pressure. A diaphragm 26 which constitutes the pressure sensitive means is exposed to the pressure drop across the orifice 17 through passages 27, 28, such pressure drop being opposed by a loading spring 30 adjusted by a pilot's control lever 32. The diaphragm 26 adjusts the control valve 33 of a servomotor 10 which in turn adjusts the angularity of the swash plate 8 of the pump 7. The servo control valve 33 is supplied by a branch 34 from the pipe line 12 a further branch 34A supplying fluid continuously to one side of the servopiston 9. The other side of the servopiston is supplied from a conduit 35 .connecting the servo control valve 33 to a sump 5, at a point between restricted orifices 37, 38 of which the orifice 38 provides the greater restriction. By suitable choice of the valves 20, 23 and the orifices 15, 17, 19, the effective area of the orifice 17 may be arranged to vary directly as the engine intake pressure, and a function of the effective areas of all the orifices, which is given in the specification, may be arranged to vary as a desired function of the air intake temperature. As a result, the actual fuel flow for each position of the lever 32 is that appropriate to the highest efficiency of the engine for the particular engine intake pressure and temperature conditions. If desired, the flow restricting means 13 may be arranged in the suction pipe 6 of the pump 7. Alternatively a constant delivery pump may be used in conjunction with a byepass relief valve. In this case the fuel delivery is controlled by adjusting the spring or other loading of the relief valve, or by adjustment of a throttle valve in the pump delivery.

Title: Improvements in or relating to hoeing and like implements
IPC: A01B35/14
Filed: 1932-06-04
Abstract: 402,764. Implements for working land. MILLER, G. J., Court Lodge Farm, Chelsfield, Kent. June 4, 1932, No. 13023. [Class 6 (i).] In a trailing implement attachment for a farm tractor of the self-supporting type the implement is adapted to be raised and lowered about a horizontal coupling-bar 7 by a handlever 3 mounted upon a bracket 1 at the side of the tractor in front of the driver's seat and the driving wheels. The coupling-bar 7 is mounted on a bracket 9 at the rear of the tractor and carries a pair of universal joints 12 which are connected to the frame 13 of a rearsteered hoe. The bar also carries a pivoted arm 14, coupled to the lever 3 by a wire or chain 15 and to the frame 13 by chains 16, 17. When it is required to use the hoe in rigid alignment with the tractor, a plate 21, pivotally mounted on the shaft 7, is swung down to engage between the limbs of a U-shaped plate 22 bolted to a plate 23 on the frame 13 ; alternatively this may be effected by bolting crossed bracing bars to the frame 13. The hand-lever 3 is locked in its two operative positions by a latch bar 24 notched to engage a pin 25 projecting laterally from the bracket 1.

Title: Method and apparatus for producing a continuous tobacco rod
IPC: A24C5/34
Filed: 1960-04-12
Abstract: 945,839. Cigarette-making machines. K. KÍRBER. April 12, 1960 [July 18, 1959], No. 13028/60. Heading A2C. [Also in Division G3] In a method for equalising or levelling a tobacco stream in which inequalities are removed from the upper surface of the tobacco stream, both the equalised tobacco rod and the unequalised tobacco stream from the distributer are measured, the two measurement values are compared and a modification of the trimming plane is effected until the difference of the two measurements is zero. As shown, a cigarette rod-making machine comprises a distributer 1, a receiving belt 2, a forming wheel 3 consisting of a primary wheel 4 with a suction groove and a secondary wheel 5 with a groove having a carded surface at its base, a trimming device 6, a forming belt 7 and rod-forming mechanism 8. A guide duct 9 transfers tobacco withdrawn by the trimming device to the secondary wheel 5. A carding roll 10 picks the tobacco off the secondary wheel 5, which rotates more slowly than the primary wheel to provide a minor tobacco stream of manageable crosssection, and spreads it on to the tobacco stream on the belt 2. By this arrangement the tobacco stream carried by the belt 2 is underlaid by the minor stream as regards the position at the trimming point. A radiation source and ionisation chamber system 11 measures the tobacco stream coming from the distributer 1 and a similar measuring appliance 12 measures the cigarette rod. The measurements of the two appliances 11 and 12 are supplied to the differential amplifier 15. The output measurement of the differential amplifier 15 is supplied to the control device 17 for regulating the upward and downward movement of the trimming device 6 and this raises or lowers the trimming device 6 until the two measurements correspond. The control impulse from the measuring appliance 12 is utilized both for controlling the distributer and for the difference measurement above. For the control of the distributer the measurement value obtained from the appliance 12 is compared with a standard value. For this purpose the measurement value supplied by the appliance 12 is fed to a control unit 22. If the measurement value received from the appliance 12 differs from the standard value the control unit 22 delivers a control signal to the control unit 19 which alters the speed of the distributor. This in turn alters the measurement value of appliance 11 which will alter the height of the cutting plane so that the measurement value of appliance 12 returns to the standard value.

Title: Improvements relating to electric torches
Inventor: CHUEN TANG WING
IPC: F21Y101/00
Filed: 1954-05-05
Abstract: 755,275. Electric torches. TANG FUN KEE MANUFACTURING CO., Ltd. May 5, 1954, No. 13057/54. Classes 39(2) and 75(4). An electric torch provided with a focusing- reflector located within a lamp housing detachably secured to the body of the torch is adapted to project white or coloured light alternatively through an aperture in a cap member by providing at least one set of light-permeable coloured plastic segments between the reflector 16 and the cap member 1 so that they can be operated to move in unison from an open or retracted position, in which they do not obstruct the light rays, towards the centre into a closed position in which they form a colour screen extending across the reflector. In the example the plastic segments 6, Fig. 3, are arranged in overlapping relation and carried by simultaneously operable toothed sectors 7 which are engaged by a rotatable toothed annulus provided with a finger operated knob 14, so that the segments can be opened or shut similarly to an iris diaphragm. Two separate sets of segments of red and green plastic material respectively are provided, one set being closed above the bulb 19 by movement of the knob 14 to the right, and the other by movement of the knob to the left. The knob is secured on the lower end of an arm 13 which is riveted at its upper end to the edge of an annular disc 12 located between edge flanges formed on upper and lower annular discs 10, 11 which are dished upwardly and downwardly respectively, rotation of the disc 12 in one direction being communicated to the upper disc 10 by an upwardly projecting lug 35, Fig. 6, on the former coming into abutment with a downward lug 44, Fig. 10 (not shown) on the latter. Rotation of disc 12 in the other direction is communicated to the lower disc 11 by the abutment of a lug 36 and a lug 45, Fig. 11 (not shown). Each of the discs 10 and 11 is provided with a series of holes adjacent to its periphery to receive pivot pins for metal sectors 7 to which the plastic segments 6 of the respective colours are attached. The teeth of the two sets of sectors 7 are engaged by vertical teeth on the inside edges of stationary rings 4 and 5 of U- shaped channel section, the ring 4 being inverted relative to 5. The return of the discs 10, 11 to their normal positions in which the coloured segments are retracted, is assisted by a wire coil spring 31, Fig. 6, surrounding the central hole of the intermediate disc 12 and with both ends projecting laterally in the same direction, so that one is engaged by a lug 32 struck downwardly from the upper disc 10 and the other by a lug 33 struck upwardly from the lower disc 11 and extending through a slot 34 in the disc 12. The screw-threaded metal end cap 1 has a central hole the surrounding edge of which bears on the bevelled edge of a glass 2 and retains it upon a beaded seating on a disc 3 located between the cap 1 and the inverted channel ring 4. The bulb 19 is pre-focused and held within a screw-threaded holder 20 by a locking ring 21.

Title: Improvements in or relating to television scanning standards convertors
Inventor: MACNAMARA TERENCE CAMERON
IPC: H04N7/01
Filed: 1955-05-06
Abstract: 801,140. Television. HIGH-DEFINITION FILMS, Ltd. May 7, 1956 [May 6, 1955], No. 13197/55. Class 40 (3). In an arrangement for converting image signals from a first set of scanning standards to a second set of scanning standards which includes the steps of reproducing a visible or electron image by the first standards and scanning this image by the second standards to produce signals having the latter standards, undesired changes in amplitude of the latter signals are reduced by including a recurrent control signal in the original image signals so that it forms part of the reproduced image and employing this control signal, after conversion to the second set of scanning standards, to reduce the undesired amplitude changes. Such changes are found to occur when the frame scanning rates of the two standards differ the amplitude varying at a rate equal to the difference in the two frame frequencies. Fig. 1 shows an embodiment of the invention which is concerned with converting sequential type signals reproduced as an image 1a on tube 1 to interlaced type signals by scanning the image by means of a television camera 5 to which interlaced scanning control signals are supplied. In accordance with the invention a control signal comprising pulses having an amplitude equal to peak white and occurring during the line retrace periods of the first scanning standard is derived from a generator 3 and combined with the original image signals in mixer 2 for application to tube 1, the blanking pulses applied to this tube being made narrower than usual to allow the control signal to appear as a strip S of standard light intensity (i.e. peak white) down one side of the image 1a. To allow signals representative of this strip to be produced by camera 5 the line blanking pulses applied to control unit 6 asociated with the latter are also made narrower than usual, such pulses being derived from a special generator 7 controlled by a normal interlaced pulse generator 8. The image signals from camera 5 are then supplied, via unit 6, to a gate circuit 10 controlled by the narrow blanking pulses from generator 7 to select only that portion of the signals which corresponds to the scanning of the strip S. Such signal portion comprises the peak white pulses which, after conversion, also exhibit the undesired amplitude variations of the image signals and to reduce the latter the pulses may be integrated to give a correction waveform for controlling the modulator 9, to which the composite output signal from unit 6 is supplied or, alternatively, they may be employed to operate a clamp circuit (in modulator 9) which adjusts the amplitude of the signal at the beginning of each line scan. The output of modulator 9 is fed to a blanking stage 11 which blanks out the peak white pulses and the converted signal is then combined with conventional interlaced synchronizing signals to produce a signal having the required scanning standards.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 25, 1946.] [Class 43] A collar-stud comprising a base 1, and a head 3 which is integral with the stud-neck 2, or is rigidly connected thereto, both head and neck being of a flattened shape is characterised in that the head is displaced sideways, so that it projects further from one edge 6 of the neck than the other 7 and thus forms a locking angle 9, the neck being secured to the base at a point displaced relative to the base in a direction opposite to the displacement of the head relative to the neck. The head is wider than both the neck and the length of the stud-hole, and its perimeter lies inside an imaginary circle 8 centred at the apex of the locking angle 9, the radius being smaller than the width of the head. The head may be of a smaller width than the stud-hole, and is then inserted in the longitudinal direction of the stud and displaced to one side,. The stud-neck may be wide enough to fill the stud-hole entirely, and may be short enough to cause compression of the shirtband and collar when in position. In Fig. 3 the neck is narrower than before and another locking angle 10 is formed at the neck edge 7 ; in this case the neck may be rounded in cross section and may merge into the plane head. The stud head may be curved to offer a bearing surface for the knot of the tie ; for similar purposes it may be bent outwardly from the plane of the stud-neck. In Fig. 7 the head is elastically compressible, being provided with a resilient threadlike extension 11, the outer end 12 of which is thiust into an aperture in the lower portion of the head, the head and neck being preferably made of steel or other resilient material. The stud may be made of celluloid, synthetic resin, sheet-metal, etc., and the base, neck and head may be made integral by press-moulding,.

Abstract: 133,270. Carrington & Sons, S. R., Carrington, W. E., and Smith, H. May 9, 1919. Stretching in manufacture.-In machines in which hat brims are gripped between pairs of arms which are afterwards forced apart, the arms are returned to their initial positions by means of a weight. The pairs of arms a, b, and c, d, are caused to approach one another vertically by a cam (not shown), which actuates a lever g having an arm h which presses on the upper pair of arms a, c. The same cam forces the lower pair of arms b, d apart laterally, and lugs e, f on these arms cause the upper pair to follow the motion of the lower pair. The lower arms are connected by a rope or the like l, which passes over pulleys o, r, and around a sheave q from which depends a weight s, the connexion being such that the weight tends to cause the arms b, d, and consequently also the arms a, c, to approach one another. The gripping faces of the arms are formed of blocks t of hard wood, having the grain perpendicular to the gripping surfaces, and provided with teeth on those faces.
