Filed: 1966-07-29
Abstract: 1,199,918. Coating BURMAH OIL TRADING Ltd. 28 July, 1967 [29 July, 1966], No. 34247/66. Heading D1L. [Also in Division B2] Flexible or semi-flexible sheet material is coated with a material having a high viscosity by extruding a suitable amount of the viscous material at substantially constant volume rate onto the peripheral surface of a roller, and rotating the roller to bring the material disposed on its surface into contact with the sheet material whereby the coating material is transferred from the surface of the roller to 'the sheet material, there being no metering of the viscous material whilst it is on the roller or on the sheet other than that achieved by the extrusion. The viscous material may be extruded onto the surface of a roller by means of an extrusion die having a suitably shaped orifice and supplied with material 'by a constant displacement pump. The opposite sides of the sheet material may be coated by extruding a suitable amount of the viscous material onto the peripheral surface of an additional second roller mounted adjacent to the first roller with its axis of rotation parallel to the axis of rotation of the first roller and rotating the second roller preferably in the direction opposite to the direction of rotation of the first roller. The sheet material may be paper, paper tissues, cellulose, metal foil, textile materials or a plastics material. The sheet material may be coated with a material having a viscosity of at least 300 centistokes e.g. 12,000 to 15,000 centistokes at a temperature which the material is applied. The viscous materials may be blends of natural .synthetic waxes e.g. petroleum waxes (paraffin waxes, microcrystalline waxes or mixtures thereof), thermoplastic polymers or co-polymers e.g. polyethylene, ethylene-vinylacetate copolymers or ethylene-ethylacrylate copolymers, natural resins e.g. rosin or rosin esters, synthetic resins e.g. polystyrene. The sheet material may be coated continuously at a rate of 50 to 500 ft. per minute. In Fig. 1 a viscous coated material is fed through feed means 1 to a constant displacement delivery pump 2 driven by a variable speed drive 3. The coated material is pumped by pump 2 through a filter 4 to extrusion die 5, and extruded through the orifice 6 of the die onto the peripheral surface 7 of heated roller 8. The material is then transferred by a rotation of the roller 8 to web 9. The tension of the web may be controlled. The coated webs are useful as packaging materials and they may subsequently bonded to a further web immediately after coating to form a laminate.

Title: Improvements in the refining or purification of benzol, petrol and like light spirits
IPC: C10G25/00
Filed: 1932-12-03
Abstract: <PICT:0409816/III/1> Light spirit such as benzol or petrol is refined, after removal of any bases, by percolating at 40--80 DEG  C. through a bed of coke or other inert material with ferric sulphate mixed or not with Fuller's earth.  It is afterwards neutralized, as by filtration through solid neutralizer in a coke filter bed, and distilled. The spirit may be forced through the filter bed, which bed may be made by evaporating a solution of ferric sulphate containing the coke.  For example, benzol, free or freed from bases, is pumped from a storage tank a to an overhead tank c from which it passes through a heater d, a tank e containing the bed of purifier in a removable vessel, a cooler f, and a neutralizer g, to a still.  A byepass j, an overflow h, and a pipe i allowing return of the benzol to the tank c for retreatment, are provided. Specification 269,242, [Class 91], is referred to.

Abstract: 907,206. Transistor switching circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 4, 1960 [Oct. 12, 1959], No. 34555/59. Class 40 (6). In a circuit for controlling the connection between a power pack 3 having two separate voltage outputs V1, V2 and a utilization circuit 4, such as a transistor logic switching circuit, so that the connection of voltage V1 to the circuit 4 is only completed when both of voltages V1, V2 exceed predetermined minimum values, the voltage at point A can only reach a sufficient value to permit transistor T1 to conduct, so energizing relay L and closing contact L1 when voltage V1 is large enough to cause Zener diode Z2 to break down and develop a voltage across resistor R4 greater than that established across Zener diode Z1, voltage V2, of opposite polarity to voltage V1, being simultaneously sufficiently great to maintain transistor T2 non-conducting. If voltage V2 is not sufficiently large, transistor T2 conducts, so bringing point A to earth potential and cutting transistor T1 off. A peak-limiting diode D1 may be connected in parallel with the relay coil L.

Title: Control device for speed regulation of motors
IPC: B65H23/18
Filed: 1954-11-30
Abstract: 761,841. Electric control systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 30, 1954 [Dec. 2, 1953; Feb. 10, 1954], No. 34616/54. Class 40 (1). The speed regulating member of an electric motor, e.g. a brush rocker or the contact arm of a speed regulating resistance, is motor-driven under control of a magnetically operated followup or null type switch, the follower member of the follow-up switch or the displaced control member of the null-type switch being driven by the regulating member directly or through a selsyn system. As shown, Fig. 1, a disc 3a is rotated through a shaft 6 from the normal position, illustrated, according to the speed variation required to cause one or other of the switches 3c-3d to be closed, depending on the sense of movement of the disc 3a, relative to a concentric permanent magnet cam 3e. A corresponding contactor 2a, 2b is thereby energized to drive a pilot motor 1b to adjust the brush rocker 1a to vary the speed of the main motor 1. The brush rocker movement, through a selsyn system 4, 5 rotates the magnetic cam 3e in the follow-up sense until it assumes the normal position shown relative to the disc 3a when it opens the operative switch 3c-3d to stop the motor 1b. In a modification, Fig. 2, using a null-type switch, the disc 3a is stationary and the controlling movement is applied to the stator of the selsyn transmitter 4 or receiver 5 or to the stator or rotor of a differential selsyn 7 disposed between transmitter and receiver. This causes a corresponding rotation of the magnet 3e to energize the speed-adjusting motor 1b which as it adjusts the brush rocker la returns the magnet 3e to its normal neutral position. The selsyn system may be dispensed with and the magnet 3e adjusted directly by the motor lb, the speed of which may be reduced as the neutral position is approached. Reversing and stopping of the main motor 1 may be effected by a contact assembly geared to the member 3a. Linearity of the speed variation response of the main motor relative to the angular movement of the control member may be effected by variable ratio-gearing between the pilot motor and rocker 1a or other speed control member.

Abstract: 467,570. Converting. GENERAL ELECTRIC CO., Ltd., and THOMPSON, W. G. Dec. 16, 1935, No. 34854. [Class 38 (ii)] Relates to a converting arrangement employing discharge devices comprising an arc gap and means for periodically breaking down the gap and consists in the provision of mechanical switching means which periodically bridges the arc-gap to relieve the gap of current during the major part of the conducting period. In the form shown in the Figure, a polyphase rectifier arrangement has arc-gaps 6 and in parallel therewith a commutator switch 13 driven by a motor 11 at a speed corresponding to the frequency of the supply, the rotor position being adjusted so that the arc-gaps become conductive just before the commutator switch closes and cease conducting just after the switch opens. In this way sparking at the commutator switch is prevented. Means may be provided for adjusting the moment of ignition, the commutator also being adjusted. If desired this may be effected automatically. In a modification the commutator switch connections on the transformer side are connected to tappings on the secondary windings to compensate for the larger voltage drop across the arc than across the switch. In a further modification the commutator switch is provided with trailing segments following each main segment and connected thereto through graded resistances so that at the end of a conducting period resistance is progressively inserted in circuit to reduce the current. In a further modification the resistances are varied with load either mechanically or by forming them from resistance material having a negative temperature coefficient of resistance. Specification 429,060 is referred to.

In a cutting tool mounting attachment for a lathe the cutting tool is automatically lifted from the work at the end of the cutting run and the lathe drive reversed so that the cutting tool is returned to its starting position. The attachment comprises a shaft 2 with an eccentric head 6 carrying a cutting tool 7. The shaft which is rotatable is axially located in a clamping portion 1 to which is attached a casing 12 housing a switch 16. Within the casing and connecting ends 14 and 17 of the shaft and switch respectively is a shifting head 15 rotatably movable by means of a lever 27. A rotatably adjustable disc 22 is located coaxially in the casing and is connected to the shifting head by a spring 25. The lever is rotatable through a 90- degree arc in a slot 34 in the casing. This movement is conveyed to the shafts 2 and 17 by the shifting head 15 the extreme positions being determined by a pin 9 in slot 10 (Fig. 3, not shown) in the clamping portion 1. In operation the lever 27 is moved manually to an extreme position so as to engage the cutting tool with a workpiece. In this position the switch is actuated to start the lathe. The forces acting on the cutting tool in operation hold the lever in this position against the tension of the spring 25. At the end of the cut, the tool leaves the workpiece and the spring force returns the lever to the other extreme position which effects the reversing of the motor to return the tool and attachment to its starting position ready for the manual operation of the switch to commence another cutting operation. The lever 27 is axially displaceable into a neutral position and retained therein by spring catch means.
