Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/47
Filed: 1935-10-04
Abstract: 463,654. Cigarette-making machines. BINGHAM, A., and MOLINS MACHINE CO., Ltd. Oct. 4, 1935, No. 27416. [Class 130] In making mouthpiece cigarettes by uniting aligned adjacent stubs and cigarettes by securing wrapping material to or around them while they are moving axially, axially aligned stubs which have ends closely abutting are fed to the machine and means are provided to space the stubs apart from each other longitudinally. Stubs fed from a hopper into the flutes of a rotating drum 3 are each cut into three pieces which are retained on the drum by peripheral guides 8. The outer stubs fall away a little from the flutes but the centre ones are retained by a closer guide plate 9 formed with camshaped edges which engage the ends of the outer stubs to separate them from the inner ones. A fluted drum 10 feeds the separated stubs to a second conveyer comprising a fluted drum 16 where side plates 14 close the outer stubs axially on to the central stubs, the stubs being again separated by guides 17 ...19, of which the outer guides 17, 19 are disposed further from the drum 16 than the central guide 18 which is formed with cam-shaped edges to separate the stubs again. The stubs slide down inclines from the drum 16 and fall singly, under control of reciprocating plates, on to a disc conveyer, pivoted fingers, operated by the plates, positioning them thereon. The disc conveyer feeds them to or between spaced cigarettes moving axially.

Abstract: 1,205,981. Reciprocating pumps. TOWLER HYDRAULICS Ltd. June 11, 1968 [June 14, 1967], No.27504/67. Heading F1A. A reciprocating pump assembly comprises a primary pump A, and a hydroculically actuated secondary pump B having a plunger 8, the larger end face of which is connected to the cylinder of the pump A, the smaller end operating in a pump cylinder. Fluid displaced by the pump A raises the plunger 8. "Boost" oil is supplied under pressure to a part 11 and to the pump cylinder by way of ducts and a valve in the plunger 8, which is thereby returned towards the lowest position, in which it closes part 11 and is thus brought to rest. An electric motor Fig.3, (not shown) drives both the primary pump A and a "boost" supply pump; with no pressure in the system at the outlet of pump B the full delivery of A is fed into the system through a check valve, and a valve controlling the "boost" oil supply is in the closed position. At a predetermined pressure "boost" oil to the part 11 is admitted by the valve and B starts to pump, the output of A serving solely to reciprocate B. The system pressure continues to rise until the pressure driving B is fully discharged through the relief valve.

Title: Process for the deoxidation and purification of copper
IPC: C22B15/00
Filed: 1934-03-13
Abstract: In a process for deoxidizing copper by the violent intermixing of the bath of copper with a molten and fluid slag capable of absorbing the oxides contained in the metal, a metalloid whose oxidation product is more readily absorbed by the slag than copper oxide, is added to the metal bath before or during intermixing or between two successive intermixings, the quantity of metalloid added being lower than that for which the solubility at saturation in the copper of the oxidation product of said metalloid would be exceeded.  Examples of such metalloids are phosphorus, silicon and arsenic and the amount used is less than 5 per cent.  The slags used contain lime as the main constituent together with oxides of manganese, sodium, iron, magnesium, and aluminium.  Specification 409,911 is referred to.

Title: Method and apparatus of producing projections on glass surfaces
IPC: H01J29/02
Filed: 1956-09-10
Abstract: 831,980. Glass manufacture. OWENSILLINOIS GLASS CO. Sept. 10, 1956 [Sept. 20, 1955], No. 27556/56. Class 56. Projections are formed on a glass surface, particularly on the interior wall of a face plate for a cathode ray tube, by softening a localized area of the wall, establishing pressure contact between a portion of the softened area and a forming tool, and shaping the softened area. The depth of the softened glass is less than the thickness of the glass so that the exterior face of the wall is not distorted. The tool may be associated with vacuum means for drawing the surface of the glass into the recess. In Fig. 1, the cathode-ray tube face plate 15 rests upon locating buttons 18 and is positioned by two pairs of opposed fixed and movable rollers 24a, 24b, the rollers 24b being vertically movable by fluid-pressure means 25. The forming tools 19 are each moved towards the glass wall, by fluid-pressure means 16, through an annular burner 23 which is supplied with fuel at 23b and plays upon the glass wall to soften a limited area and depth thereof. Vacuum may be applied to the tools 19 through passages 19b, 17b a plug 19d, with very small axial grooves, permitting the vacuum to be applied to the tools but preventing glass from being drawn into the passage 19b. A motor-driven shaft 28 carries cams 30a, 30b, 30c, 30d which control vacuum supply valves 26a, 26b and fluidpressure supply valves 27a, 27b. The valves are operated in sequence so that the rollers 24b are forced up to grip the face plate in virtue of the slight taper of the flange 15a, and after a period sufficient for the burners 23 to soften the glass, the tools 19 are moved into contact with the glass and vacuum is applied to the cavities in the tools. Application of vacuum to the cylinders 16 and 25 permits the face plate to be removed. The shapes of the projections may be varied by altering the shapes of the recesses in the forming tools and the face plate may be thickened on the flange at the positions to be provided with projections so that any substantial reduction in wall thickness is avoided.

Title: Improvements in or relating to apparatus for the manufacture of dough-sheets
IPC: A21C3/02
Filed: 1936-10-13
Abstract: 469,919. Moulding dough. LOOSEWILES BISCUIT CO. Oct. 13, 1936, No. 27767. Convention date, June 5. [Class 87 (ii)] Apparatus for making thin, ribbed, dough sheets comprises two rolls 2, 3, the roll 3 being circumferentially grooved at 5 and a straight-edged deflector blade 10 engaging the ridges of the grooves to remove the sheet therefrom. To prevent wearing of the blade into the grooves, the blade and ridges are moved relatively either by forming the roll with helical oblique or waving grooves or by reciprocating the blade crosswise of the grooves. In that case, the blade 10 is adjustably mounted on a carriage 11 comprising two cross-shafts 12, 13 adapted to have limited sliding movement cross-wise of the machine frame and reciprocated by a cam acting on a cam follower on the shaft 13. The blade 10 rests on spring- yielding buttons 24, Fig. 3, in the carriage 11, and is held against sliding lengthwise on the carriage by bolt heads secured to the blade engaging slots in the carriage. The blade is prevented from backing away from the roll by adjusting thumb screws 23. The blade is pressed against the roll by thumb screws 25 engaging fingers 26 secured to the blade. The screws 25 are mounted on bolts 27 pivoted on the machine frame. The ribbed dough sheet is fed by a conveyer 35 to a receiving surface 37 where it is lapped or folded. The roll 2 may be provided with a blade 8 and a wiper 9. It may have adjusting mechanism 4. The dough-folding mechanism comprises a bar 39 reciprocated by slide rods 40 from a crank 43, connecting-rod 45 and cross-head 42. The rods 40 slide in bearings 41 which may pivot about axes 47 or may be locked by pins 48. The cross-head 42 is jointed to the rod 45, but the joint may also be locked by a pin.

Abstract: 721,422. Automatic frequency control systems. RADIO CORPORATION OF AMERICA. Nov. 4, 1952 [Nov. 19, 1951], No. 27783/52. Class 38 (4). A microwave generator 10 whose frequency is to be stabilized has its output applied directly over paths 14, 20 to one arm of a bridge, shown as a magic T, and over a gas cell 22 to the opposite arm 30, the other two arms 34, 36 containing oppositely poled rectifiers 38, 40 connected to one end of a resistance 55 to provide a control voltage over path 56 for stabilizing the frequency of generator 10. The energy from arm 32 is in opposite phase at the equally spaced rectifiers 38, 40, while the energy from arm 30 is in phase at rectifiers 38, 40, so that if phase adjuster 26 is set so that the energy fed to arms 32, 30 is in phase quadrature, the rectifiers produce equal and opposite voltages which cancel at resistance 55. If now, the frequency of the generator 10 varies, the phase of the energy from the gas cell is varied, and the voltage developed across 55 is of sign and magnitude dependent on the variation of phase from cell 22. Reference has been directed by the Comptroller to Specification 663,065.

Title: Improvements in polar coordinate aiming devices
IPC: G06G7/80
Filed: 1955-09-30
Abstract: 816,327. Electric analogue calculating. CONTRAVES A.G. Sept. 30, 1955 [Oct. 16, 1954], No. 27874/55. Class 37. [Also in Group XX] In a tracking system, polar co-ordinate data are generated by continuously variable speed motors on the assumption that the object tracked is following a straight path and if the observed coordinates differ from the generated values, manual corrections are applied to correct the co-ordinates and the data which define the flight path, the whole mechanism operating throughout in polar co-ordinates. Thus in a sighting device shown in Fig. 2 operators at 6, 7, 8 observe the target and if, for example, the generated azimuth co-ordinate is incorrect the operator re-aligns his sight with the target by operating the hand wheel 60, thus applying the correcting quantity #α. The other operators apply corrections ## and #r by the hand wheels 70, 80 to the elevation and range co-ordinates. The mechanism shown in Fig. 3 comprises motors M which run at speeds proportional to the applied voltages. The motors are also supplied with an exciting voltage 1. The corrected azimuth co-ordinate is obtained by adding in a differential D the quantity #α applied by the hand wheel 60 and the quantity generated by the motor M running at a rate determined by voltages, added in the + device, which respectively represent the generated value α and a fraction of a voltage # produced by a generator G to represent the product of the speed of the generator and a reference voltage 1, the fraction being produced by a voltage dividing device P. In a similar manner corrected elevation and range co-ordinates are produced from generated quantities A and r and the corrections ## and #r fed in by the hand wheels 80, 80. The quantities α, # and r are generated in accordance with the equations: In the diagram addition is indicated by +, the change to negative by -, and multiplication by x. Electrical connections are indicated by single lines and mechanical shafts by double lines, the quantities represented by the voltages or rotations respectively being as indicated, the quantities represented by shaft rotations being underlined. The quantities Iα, I#, Ir correspond to the similarly designated equations above. The Specification also describes a simplified construction which operates only in terms of α and r and so is suitable for use when tracking an object moving in a horizontal plane. Each of the above equations involves all of the co-ordinates α, #, r and derivatives thereof. It is shown that equations can be derived each involving only one co-ordinate and its derivatives. Computing arrangements operating in accordance with these equations are described. Specifications 733,086 is referred to.
