Title: Improvements in or relating to electric coils
IPC: H01F41/06
Filed: 1955-12-21
Abstract: 771,825. Electric coils. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 21, 1955 [Dec. 24, 1954], No. 36654/55. Class 35. In a rectangular electric coil wound with its turns in planes at right-angles to the axis, each coil having a cranked portion passing from one plane to the next, this cranked portion is prevented from progressing from a flat part of the coil to a corner by causing it to reverse its progression after a certain number of turns. As shown in Fig. 1, the winding is commenced with turns 1, 2, 3, &c. having cranked portions 11, 21, &c. At the end of the layer, turn 6 rises up into the next layer so that subsequent turns, e.g. 7, lie between turns of the first layer, except for the cranked parts which naturally ride over the thickness of the wire producing a hump in the coil. As shown, the cranked part tends to be progressively displaced along a line A<SP>1</SP>, B<SP>1</SP> and then B<SP>1</SP>, C<SP>1</SP> and would eventually reach the corner of the coil and upset the winding. To avoid this the progression is reversed after a few layers have been wound, by spacing the turns as shown in Fig. 6. This may be achieved by reducing the wire diameter, e.g. by increasing the tension or by compression between rollers to flatten the wire slightly. Alternatively the winding mandrel may be stepped so that at a certain diameter the winding length is increased by about 10 per cent of the wire diameter. Alternatively a sector of the winding space may be enlarged, so that as the cranked part progresses into this sector its direction is reversed. A further alternative is to suddenly increase the pressure of a leather pad bearing on the coil as it is being wound. If desired, the progression may be reversed several times.

Title: Fluid flow measurement
IPC: G01F1/704
Filed: 1957-11-25
Abstract: 862,891. Measuring fluid flow. CALl- FORNIA RESEARCH CORPORATION. Nov. 2.5, 1957, No. 36665/57. Class 69 (1). [Also in Group XL (b)] The rate of flow V of a fluid stream is determined by injecting a known quantity A of radioactive isotope material into the stream and obtaining the total number N of counts produced in a radiation detector positioned at a downstream point during the passage of the quantity A. Relative rates of flow can be determined from the relationship V α A/N which can be modified by a proportionality factor F determined by the detector response and the geometry of the system to enable the absolute rate of flow to be determined using the relationship V = FA/N. A known amount of radioactive material 15, Fig. 1, is injected into a fluid stream 11 at point 12 and the counting pulses produced in the Geiger-counter 23 are supplied to an integrating circuit 25 which totals the counts received during the passage of the injected isotope. The proportionality factor F is obtained using the arrangement indicated in Fig. 2, in which a section of pipe 30 similar to pipe 10 is filled with the fluid comprising the stream 11 and the counting rate of the detector 23 is noted when a known amount of the radioactive material 15 is introduced, F is then calculated in counts per unit time registered from one unit of radio-activity per unit volume of fluid. From the values obtained for A, N and F the rate of flow at point 12 may be determined. Automatic measurement of fluid flow rate can be arranged by periodically introducing the isotope into the stream. Figs. 4-7 (not shown) indicate the application of the arrangement to the measurement of fluid flow in branch pipes and streams.

Title: Method of and apparatus for slitting relatively stiff material in sheet form and stacking the separated parts of such material
Inventor: BEER CLIFFORD NORTHMORE
IPC: B21D43/22
Filed: 1961-10-12
Abstract: 993,011. Sheet delivery apparatus. WEYBRIDGE MACHINE TOOL CO. Ltd. Jan. 8, 1963 [Oct. 12, 1961], No. 36694/61. Heading B6H. [Also in Division B8] A method of slitting sheets (e.g. metal sheets) and stacking the separated parts, comprises passing the sheets through slitting apparatus and immediately thereafter allowing the separated sheet parts to fall gravitationally on to platforms on opposite sides of the longitudinal slitting line, lowering the platforms progressively or step-by-step as the sheet parts are added thereto, and depositing the stacks on means enabling such stacks to be discharged from the platforms. Metal sheets are slit longitudinally into two parts and the two parts supported at their adjoining edges as they leave the cutting apparatus by a bar 11. The free edges of the parts tip under the influence of gravity and the parts fall on to stacks 44. Each stack is supported by battens 27 carried by fourspaced, parallel, L-shaped arms 24. The latter are secured together by cross-bars 25 and mounted on a shaft 23 supported at each end by brackets 22 on carriages 15. The carriages are united by cross members 17 (not shown) and are slidable in an outer stationary frame 14. Photo-electric means 46 control hydraulic means 28, whereby the carriages are lowered as sheets parts are deposited on the stack to maintain the top of the stack at a predetermined level. Hydraulic means 30, pivotally mounted on lugs depending from the carriages, control the angular setting of the arms 24. When the stack is complete, the hydraulic means 30 is operated to swing the stack from an inclined to a horizontal position. The hydraulic means 28 is then operated to lower the stack and deposit the battens and stack supported thereon, on driven or freely rotatable rollers 41 of a feed-off unit 40. The carriages are provided with racks 21 co-operating with pinions 20 at each end of a shaft 19 carried by the outer frame 14, to ensure that the carriages move equal distances when the hydraulic means 28 is operated. The sheet parts are stabilized as they fall from the bar 11 by air blasts issuing from nozzles 45. The sheet parts are aligned at one edge by the arms 24 or a face plate secured thereto and are aligned at the two edges perpendicuar to said one edge by end plates 31, Fig. 5 (not shown). One or both of said end plates is or are adjustable in position, the end plates being mounted on a screw-threaded shaft for this purpose. Said shaft is supported by beams adapted to rise and fall with the carriages 15 and said beams carry an electric motor adapted to drive said shaft through a chain and sprocket drive whereby all the end plates are adjusted simultaneously. Specifications 955,566 and 955,567 are referred to.

Title: A process for the manufacture of blown asphaltic bitumens
Inventor: MAIR JOHN MONTGOMERIE
IPC: C10C3/04
Filed: 1955-12-23
Abstract: In the blowing of heated residual petroleum oil with free oxygen-containing gas, e.g. air, to produce a blown asphaltic bitumen, the temperature of the gases and vapours present in the vapour space is controlled by spraying water, preferably by injection through hollow cone spray nozzles, jets or perforated manifolds, in a direction avoiding water impinging upon the surface of the oil. Steam may be introduced similarly.  Rates of 0,01-1,5 gallons water and 1 to 5 lbs. steam per hour per ton of oil feed per day are specified.  In a preferred operation, steam is introduced at a fixed rate continuously and the amount of water varied to obtain fine temperature control and the temperature of the gases and vapours is maintained at least 30 DEG C. below the temperature of the surface layers of oil.  In an example 200 tons per day of an asphaltic bitumen of penetration value 120 was air blown using 8 tons steam at 140 lbs./sq. inch, and 0,5 gal. water per hour per ton of feed; the temperature of the gases and vapours was thereby maintained at 180 DEG C. \sB 5 DEG C

Title: Process for the manufacture of tubular thermoplastic films
IPC: B29C48/10
Filed: 1961-10-13
Abstract: 1,008,404. Films. FARBWERKE HOECHST A.G. Oct. 13, 1961 [Oct. 13, 1960], No. 36895/ 61. Addition to 849,466. Drawings to Specification. Heading B5B. In a process for the manufacture of films of artificial thermoplastic material wherein a heated tube of artificial thermoplastic material is disteneded by the application of internal pressure to form a tube of larger diameter while the zone of transistion between the narrower and wider portions of the tube is in an elastic state, during the distention at least two concentric annular portions of at least a part of the wall of the tube in the zone of transition are so heated that a temperature gradient or gradients are created across the said part of the wall, at least one of said concentric portions being heated to a temperature within a range extending from the crystallite melting point or softening point of the thermoplastic material to 60 C. below the said point and at least one other of the said concentric portions being in the molten state at a temperature within a range extending from a temperature slightly below the crystallite melting point or softening point to a temperature above the said point, and the wider portion of the tube is maintained in its distended state while being cooled. Specified materials include polyolefins, e.g. polyethylene and polypropylene, polymers of olefins of high molecular weight, polyfluoroethylenes and polyvinyl chloride. The concentric portion of the wall of the tube that is in the molten state may have a temperature not more than 60 C. above the crystallite melting point or softening point. Either the outer part of the wall of the tube or the inner part of the wall of the tube or both may be heated to a temperature above the crystallite melting point and the remainder of the wall of the tube may be maintained at a temperature within a range extending from the crystallite melting point or softening point to 60 C. below the said point. Alternatively, an annular portion of the wall of a tube issuing from an extruder in the molten state may be cooled to a temperature within a range extending from the crystallite melting point or softening point to 60 C. below the said point. Heating of the film may be effected by passage through a bath or spray of a hot liquid, or a blast of hot gas, or by radiation. Films so made have strengths from about 200-1000 kg. per sq. cm., and corresponding elongations from about 50 to several hundred per cent, e.g. 500%, the strengths and elongations of the films obtained being varied by variation of the temperature distribution across the wall of the tube. This may be achieved by varying the bath temperature or the velocity at which the tube is fed into the tempering bath or other tempering device.

Filed: 1959-11-06
Abstract: 933,767. Automatic steering control. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Nov. 6, 1959 [Nov. 6, 1958], No. 37704/59. Class 38 (4). In an automatic pilot automatic control of a control surface is entirely eliminated and motoroperated control means set to zero automatically when manual steering is initiated. In Fig. 2 a ship's rudder (not shown) is automatically controlled by a signal generator 9 operated in either direction, through gearing 8 and against the action of a spring 10, by a gyro-compass repeater motor 7 to maintain a course which is indicated on a dial 4 of a further compass repeater motor 1. Operation of independent manual steering (not shown) disengages automatic steering, opening a switch 6 to de-energize motor 7 and permit spring 10 to return generator 9 to a zero position. When automatic steering is restored after setting a new course, pointer 17 indicates any deviations from that course. Switches 22, 23 operated through a slipping clutch 20 in dependence on the sense of automatic correction are utilised for anti-hunt purposes. A limit switch 16 operated on excessive movement of signal generator 9 operates a warning device and causes switch 6 to open. In one modification, the two compass repeater motors are replaced by a single motor and generator 9 is released by disengagement of an electromagnetically operated clutch and restored to its zero position by a spring-urged member acting on a heart-shaped cam. In this arrangement course deviations are indicated by a second pointer associated with dial 4. In another modification generator 9 is restored to its zero position by relative rotation of two portions of an obliquely cut cylinder urged towards each other by a spring. In a final modification, contacts cam-operated by generator 9 control a reversible motor which restores generator 9 to its zero position when automatic steering is disabled. Application to course setting from remote stations connected by wire or ratio is referred to.
