Abstract: 1,059,505. Feeding sheets. SCHNELLPRESSENFABRIK A.G. HEIDELBERG. Jan. 13, 1965 [March 6, 1964], No. 1523/65. Heading B6B. In sheet feeding apparatus wherein an auxiliary pile table is used to support a depleted pile, so that the main table can be replenished and thus enable sheets to be fed continuously from the apparatus, the auxiliary table 1 is fitted on the main table 12, Figs. 5, and 9 to 16 (not shown), and comprises a lattice-like frame 2 in which there are two groups of rollers 5, the surfaces of one group projecting beyond the upper surface of the table 1, and the surfaces of the other group project beyond the lower surface of the table. The frame 2 has handles 3, extensions 8 for engagement by an auxiliary pile raising means, and has webs 6 which support the ends of the rollers. A narrower frame 4 secured to the frame 2 has roller supporting struts 7 which are reduced in height in a stepwise fashion, so that they taper towards their free ends. In the frame 2, there are several groups of rollers 5, each group comprising two rollers, one above the other and of equal diameter; and the frame 4 comprises several groups of rollers which decrease in diameter to suit the stepped struts 7. In modifications, a larger lower roller co-operates with two offset upper rollers, Figs. 8 and 19 (not shown), or upper and lower rollers are offset so that they do not touch each other, Fig. 17 (not shown). In use, the auxiliary table 1 is placed directly on the main table 12, and located thereon in some cases by a ribbed guard frame 10, Fig. 4 (not shown), and the pile table 12 is raised intermittently by a conveyer 21, Figs. 9-16, as sheets are separated from the top thereof by suckers 22. When the pile is depleted to a predetermined extent, an auxiliary conveyer 20 engages beneath the extensions 8 of the auxiliary table 1 and continues the intermittent raising of the pile. The main table 12 is lowered, a second auxiliary table 1 is placed thereon, a new pile is stacked on the combined tables, the new pile is raised until the top sheet thereon engages the first auxiliary table 1, and the latter is then gradually pulled out so that the depleted pile rests on top of the new pile: all this is accomplished during the continuous separation of sheets by the suckers 22. The rollers 5 &c. in the auxiliary table 1 facilitate easy withdrawal from between the two piles. In modifications, the rollers 5 &cmay be driven through chain means by a handcrank, to facilitate easier withdrawal of the table; or a strap &c. 25, Fig. 18, can be pulled against the action of a return spring, from a " roller-blind " means 26 to drive all the rollers 5, 5<SP>1</SP> frictionally as the table is withdrawn.

Abstract: 810,586. Extruding plastic material. WESTERN ELECTRIC CO. Inc. Jan. 17, 1956 [Jan. 24, 1955], No. 1567/56. Class 87(2). [Also in Group XXX] Solid plastic material (resins, rubber) is fed into an extrusion chamber, advanced, compacted and worked along a first portion of the chamber and then, in a second portion of the chamber, has its flow accelerated at a substantially constant rate whilst it is worked more intensely than in the first portion, and is discharged through an extrusion die. The worked material leaving the second portion of the chamber is worked with maximum intensity in a third portion, before discharge through the die. The invention is described in connection with a crosshead extruder for coating wires, solid plastic material being fed into a jacketted extrusion chamber 20, Figs. 2 and 3, through which it is pushed by a single-flight internallyheat-controlled screw 30 through a filter 36 to emerge at a die 53 where it coats an advancing wire 15. In the first portion of the chamber, A-B, the helical screw channel 75 is deep and of a depth that decreases in the feed direction, the material being conveyed along and compacted. In the second portion B-C the depth of the chaniiel 75 is a hyperbolic function of the length along the longitudinal axis of the screw, decreasing hyperbolically from point B to point C, whereby substantially constant acceleration is imparted to the material and the velocity of the material increases uniformlv from B to C. In the third portion C-D the channel 75 has a constant depth equal to the minimum depth in the portion B-C. Fig. 4 shows the variation in channel depth along the length of the screw. At the point B the material is beginning to melt and at the point C it is entirely molten. In a modification, Fig. 7, the central portion B-C of the screw is in the form of three frustoconical sections B-B<SP>1</SP>, B-B<SP>11 </SP>and B<SP>11</SP>-C of such shape that the portion B-C forms a channel the depth of which is approximately a hyperbolic function of the length B-C.

Title: Improved method of production, without catalyst, of synthesis gas from oxygen and hydrocarbons obtained by vapourization of petroleum products
Filed: 1956-01-23
Abstract: Modification of the parent Specification wherein a vaporized hydrocarbon oil is used instead of a gaseous hydrocarbon. According to the parent Specification in the production of synthesis gas by the non-catalytic interaction of a gaseous hydrocarbon and oxygen, the reactants are premixed and passed into the reaction chamber in streamline flow parallel to the axis of the reaction chamber by mutual impact of the two gas streams, the components of the kinetic energies of the two streams perpendicular to the general flow of the resulting mixture being substantially equal.  Liquid hydrocarbons specified are petroleum fractions capable of distillation at or below 320 DEG  C. at atmospheric pressure, e.g. gasoline, naphtha, and kerosene, and crude oils capable of only partial distillation at or below 300-350 DEG  C.  The apparatus of the parent Specification may be associated with an evaporator for the liquid hydrocarbon and the hydrocarbon may be heated by heat exchange with the synthesis gas produced.

Title: Improvements in and relating to brush control gear for alternating current commutator motors
Inventor: LANE ARTHUR CLIVE
IPC: H02K23/18
Filed: 1954-01-26
Abstract: 747,121. Brush-gear for dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 13, 1955 [Jan. 26, 1954], No. 2375/54. Class 35. The oppositely movable brushes of an A.C. commutator motor are moved by toothed gears which are controlled by a gear arrangement comprising a driving cam and a driven cam interconnected by a flexible member which un. winds from one cam as it is wound up on the other cam, the cams having gradually changing transmission ratios at least during a part of the movement of the control gear. A well-known arrangement is shown in Fig. 1 where a pilot motor P drives through gearing two brush rockers A, B. The present invention replaces the drive arrangement between the driving and driven shafts T, S by two cams M, N interconnected by a flexible member L as in Fig. 2 so that the transmission ratio between T and S varies with the rotation of the cams. The cams can be helical or screw shape as in Fig. 3 (not shown) whereby the shaft S can be rotated more than one revolution. In the arrangements shown in Figs. 2, 3 the member L has to be biased by a spring or weight to keep L taut when the cams rotate oppositely to the direction indicated by r 1  and r 2 . Such biasing will be unnecessary if two sets of cams N, Y and M, Q are mounted and interconnected by flexible members L, Z as in Fig. 4. The brush rockers may be rotated by hand through the cam arrangements described above.

Title: Pressurisation of enclosed chambers utilising fluid logic devices
Inventor: FURLONG OWEN DESMOND
IPC: F15C1/00
Filed: 1966-01-18
Abstract: 1,138,868. Fluid-pressure servomotor systems. WESTLAND AIRCRAFT Ltd. Dec.15, 1966 [Jan. 18,1966], No. 2386/66. Heading G3P. A fluid operated pressurization control system for an aircraft cabin 11 includes a fluid logic element for sensing the rate of change of pressure within the cabin and valve means 63 for controlling the rate of change, the valve means being preset to limit the rate of change by opposing the rate signal developed by the fluid logic elements in an associated fluid element with a regulated bias pressure which has to be overcome before the rate signal, amplified as required, becomes operative through the remainder of the system, and actuating means to control the inflow and outflow of fluid from the chamber to maintain a predetermined pressure. When cabin pressure increases, a capsule 110 is compressed to open a valve 107 to lower the pressure in lines 102 and 105 which are connected through restrictions 103, 104 to a supply manifold 5. The fall in pressure deflects a jet from nozzle 96 to an outlet 115 of a fluid amplifier 97 and causes deflection of a jet 127 in a further amplifier 126 into a line 132 to inflate a bellows 134 and to open an outlet valve 142 from the cabin against the pressure of a spring 139. A fall in cabin pressure closes the valve 107 and deflects the jet from the amplifier 126 into an outlet 130. This amplifier is also controlled by a diaphragm actuated valve 119 responding to the difference between cabin and external pressure. To limit the rate of change of pressure, an amplifier 10 connected to a capacitor C and filter 12 acts through amplifiers 23, 33 and 43 on a pair of amplifiers 59, 54 oppositely biased by the supply from the valve 67. When the bias is overcome, the amplifier 59 or 54 causes jet deflection in an amplifier 79 and in the amplifer 97 in opposition to that caused by the capsule 110. The valve 67 determines the range of acceptable rates of cabin pressure variation. A feedback from the output line 132 is fed to control jets 82, 83 of the amplifier 79 and a capacitor 87 is provided to delay the pressure change in one direction. Reference has been directed by the Comptroller to Specification 1, 085, 925.
