Title: Improvements in or relating to electric emulsion treater
IPC: C10G33/02
Filed: 1956-10-31
Abstract: 840,116. Electrostatic separators. PETROLITE CORPORATION. Oct. 31, 1956 [Dec. 16, 1955], No. 33219/56. Class 117 An electric treater for oil-continuous emulsions comprises a container 11 having a substantially horizontal baffle structure 15 electrically connected to the container and dividing the container into an upper oil zone 16 and a lower treating zone 17 containing high voltage electrodes 35...37, and one or more distributers 100 delivering emulsion to the zone 17, the zones 16, 17 communicating with each other through a narrow space 20 at the periphery of the baffle 15. The area of the space 20 is not more than 20% of the area of the container at that level. Emulsion is delivered at 102 to pipes 101 each leading to a distributer 100 having a narrow, annular discharge opening located in an inter-electrode space 38, treated oil rising through the space 20 to the zone 16 from where the oil is led off, and the remainder of the emulsion is drawn off continuously or periodically from the zone 17. The electrodes 35...37 comprise members, which may be foraminous, having a peripheral frame 42 spanned by transverse rods or pipes 43 and. if desired, reinforced by longitudinal members 44. The electrode 36 is suspended by insulated hangers 45, and the electrodes 35, 37 by insulated hangers 75. which pass through framed holes 46. 76 respectively in the electrodes 35, 36 and are adjustably secured at their upper ends by nuts 57 in housings 47, 77 respectively located on the baffle structure 15. Current is led from a high voltage source 65 by conductors 62, 82 to the electrode 36 and to the electrodes 35, 37 respectively. The structure 15 comprises separate plates 31, apertured at 63a to accommodate the conductors 62, 82, and separated by narrow spaces through which oil can pass to the zone 16. Each plate 31 is supported by brackets 32 at its outer edge and at its inner is secured to an I-beam 24 suspended by hangers 26 from the top of the container 11. A hand-wheel 137 allows the width of the annular discharge orifice of the distributer 100 to be adjusted, and a hand-wheel 130 permits rotation of the upper surface of the orifice to dislodge foreign matter therein. In a modification, the electrode 36 is earthed through the baffle 15, the parts 45, 47 being dispensed with, the electrodes 35, 37 being connected to one end of a secondary, the other end of which is earthed. In this modification, the pipe 101 extends through the top of the container 11.

Title: Gaseous discharge tube cathode
IPC: H01J17/06
Filed: 1936-12-04
Abstract: 486,767. Thermionic valves. EDWARDS, D. V., and SMITH, E. K. Dec. 4, 1936, No. 33294. [Class 39 (i)] In a discharge device containing gas or vapour at a pressure of from À005 to 1 mm. the cathode is so arranged that the perpendicular distance from the emissive surface, or a sufficient portion thereof to carry the required load, to any other surface is not less than the mean distance traversed bv an electron before undergoing an ionizing impact. For a tube filled with argon at not less than À4 mm. or with xenon at not less than À2 mm. the requisite distance is about 1.2 cms ; with À05 mm. of argon or À025 mm. of xenon a distance of 2À8 cms. is necessary. If the cathode is plane or a simple cylinder the distance is measured from the actual cathode surface, but in other cases an equivalent surface, from which the electrons may be imagined to have been emitted with zero velocity is employed. The Figure shows a valve embodying such a cathode in the form of a cylinder 3, the diameter of which is equal to the distance in question, coated internally with emissive material and heated by an external heater 4. A number of cylindrical insulated screens 5 surround its cathode. The pressure in the device should be above the pressure at which the are drop suddenly decreases with increase of pressure and above that at which the permissible anode voltage increases as.the pressure decreases. A cathode consisting of a number of helical filaments arranged in a circle is also described.

Title: An Apparatus for Measuring Functions of Tri-Stimulus Values
IPC: D06B23/28
Filed: 1967-07-20
Abstract: 1,192,765. Photo-electric determination of tristimulus values. SUMITOMO CHEMICAL CO. Ltd. July 20, 1967 [July 20, 1966], No.33390/67. Heading G1A. Known types of spectro-photometers are modified for use in measuring colour density by tristimulus integration. In one arrangement Fig 1, a Hardy-type spectrophotometer is shown having a prism-mirror system 2-4 for dispersing the light from source 1, and Rochon and Wollaston prisms 5, 5a and a polarizer 5b for separating the beam into two polarized coordinates, which illuminate a sample 12 and a white standard 11 in an integrating sphere 30. The beams are alternately detected by detector 31 and a signal is transmitted via cam 14 to a recording system. This arrangement is adapted to generate instead of the normal functions of optical density, a more complicated one, the Kulbelka-Munk function. The Rockon prism 5 is caused to rotate to balance the reflected intensities from 11 and 12 this rotation being carried out by a servomotor 20 through a cam 13 shaped to provide the Kulbelka-Munk function. The rotation of the cam-shaft is coupled through a servomotor 7 to the tristimulus integrator 10, which uses information as to the reflected light intensity transmitted thereto, to calculate the tristimulus values. The integrator 10 receives the wavelength values from a motor 9 coupled to the recorder drum 17. A different cam and link-work construction is used in another arrangement, Fig. 4 (not shown). Both arrangements can have cams shaped to transmit the Fink-Jensen function instead of Kulbelka-Munk. In a second arrangement, Fig. 3, the spectrophotometer is of the type in which a sample 9 and white standard 8 are alternately illuminated and the photo-detector output amplified in respective channels. A servosystem including a fixed resistor 4 and linear or logarithamic potentiometer 15 is used to drive the recorder pen to indicate intensity values, the wavelength corresponding to rotation of the recording drum, synchronized with the angular movement of concave mirror 3. The potentiometer is wound so that the voltage tapped off is representative of a comparison of the reflected intensities according to the Kulbelka-Munk function. This voltage fed to the tristimulus integrator 20 with wavelength information from the drum.

Title: Improvements in or relating to detent devices
IPC: F16K11/07
Filed: 1962-08-31
Abstract: 1,017,829. Coupling mechanisms; shovelling machines. HYDRAULIC UNIT SPECIALTIES CO. Aug. 31, 1962 [April 30, 1962], No. 33523/62. Headings E1F and E2B. [Also in Division F2] A detent device for an operating member that is movable relative to a support comprises telescopic members 43, 47, the inner member 43 enclosing a spring-loaded cam member 45 (Fig. 3, not shown) engageable with detent means 44 positioned in recesses formed in the inner member 43, so that, to couple the members 43, 47 together, the detent means 44 are moved apart by the cam member 45 to engage grooves 48 of the outer member 47. The coupling mechanism is released by inward movement of the cable 64 of a Bowden cable to disengage the cam member 45 from the detent means 44 so that the telescopic members 43, 47 may slide freely. The detent device may be used to control co-operation of the valve system of an hydraulic system for controlling the raising and lowering of a shovel 7, as shown in Fig. 2, the detent devices controlling the positions of valve spools 29, 30. In this application, the cable 64 is connected to a bellcrank 68 slidable along a cam bar 69 as the shovel is raised or lowered, which upon abutting a projection 71 moves the cable to actuate a screw 65, thus uncoupling the members 43, 47. The valve spools are automatically returned to their neutral position by springs 41. In alternative embodiments, a centrally positioned member is either slidably or rotatably moved inwards to disengage the member 45 from the detent means 44. The member 45 may be constructed as a ball or alternatively it may be conical shaped.

Title: Improvements in and relating to rows of nails bound together by an adhesive
IPC: F16B15/08
Filed: 1964-08-17
Abstract: 1,022,175. Strips of nails. SIGNODE CORPORATION. Aug. 17, 1964 [Aug. 22, 1963], No. 33542/64. Heading B8C. [Also in Division F2] A method for producing a strip of nails stuck together comprises arranging the nails on a conveyer with their heads in overlapping relationship and the shanks of adjacent nails lying side by side, and conveying them to a station where adhesive is applied to bind the nails together. The nails 2 are formed with a part of their heads removed from along a chord that is a tangent to the nail's shank and are stored in a hopper 4 to be fed by a vibratory feeder (not shown) into a downwardly inclined track 8 where by means of a solenoid 14 and a vibrator 26 they are brought into single file with their heads in tiered overlapping relationship and their shanks parallel but slightly separated. The lower part of the track 8 leads them on to notched straps 60, 62 on the conveyer 28 where they are deposited with the aid of magnets and guide plates. The nested nails are moved to an adhesive station C where a saturated linear terephthalate copolyester adhesive is applied on the uppermost surfaces of the shanks from a slot in a block (not shown) with the aid of wiper pads, the block being held in engagement with the row of nails by means of a weight 156 and crank arm 158. The applied adhesive is given the desired flow characteristics by means of a hot air blower 172 so that it flows between the shanks and on to their lower surfaces. The shanks are brought closer together by moving the notched strap 62 towards the strap 60 at 144 and the adhesive is then cured under a heater 174. After conveyance to a taping station D polyester tapes are applied to the upper and lower surfaces of the strip of nails, the upper surface tape 175 being fed from a reel 176 via a roller 188 and supported by a resiliently biased bracket. The glued strip is passed under a cool air blower 210 to a knife assembly E where a knife is actuated to cut off equal lengths of the strip. The movement of the knife is regulated by a hydraulic cylinder 218 and a solenoid valve 266 controlled by a switch which is adjusted to respond to a predetermined amount of movement of the notched strip 62. The severed lengths 260 are removed from the conveyer by a separately driven belt 262.

Title: Improvements in the manufacture and production of phosphoric acid and hydrogen
IPC: C01B25/20
Filed: 1928-11-16
Abstract: 325,533. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 16, 1928. Hydrogen.-In preparing phosphoric acid and hydrogen by the action of water or steam on phosphorus at temperatures of about 650-700‹C., the reaction products contain some lower oxides of phosphorus which may be converted into phosphoric acid by cooling the reaction products to a slightly lower temperature (about 600‹C.) and maintaining them at this temperature for some time preferably in the presence of catalysts, such as alloys of copper and nickel, fireclay, carborundum carbon &c. A mixture of phosphorus and steam at a temperature of 300-320‹C. enters at A a reaction vessel C and passes over a catalyst 1 of copper-nickel alloy. The reaction products acquire a temperature, due to the reaction, of 650-700‹C, and are cooled in region B to about 600‹C. by injection of water, aqueous ammonia, or a solution of acids of phosphorus obtained in washing hydrogen prepared from phosphorus and steam as described in Specification 262,455. The cooled reaction products pass over a catalyst 11 consisting of fireclay. Specification 278,578 also is referred to.

Title: Improvements in or relating to motor vehicle fuel tanks
Inventor: STOTT THOMAS CHARLES FELIX
IPC: B60K15/04
Filed: 1958-10-21
Abstract: 875,380. Filling and venting tanks. VAUXHALL MOTORS Ltd. Oct. 16, 1959 [Oct. 21, 1958], No. 33692/58. Class 21. [Also in Groups XXVII and XXIX] A motor vehicle fuel tank 1 has a filler pipe 6 and an unrestricted vent pipe 12 both communicating with the tank below the desired maximum liquid level 16, and a restricted vent orifice 18 by which the space above the liquid level 16 is vented. As shown, the restricted vent orifice 18 is in the pipe 12. When the tank is being filled, it is vented freely through the end 14 of the pipe 12 until the end 14 is closed by the rising liquid level. Thereafter, the gases trapped above the level 16 can only escape at a reduced rate through the restricted vent orifice 18 so that continued introduction of fuel into the filler pipe 6 causes the fuel level therein to rise rapidly. The filling operation is then stopped and the restricted vent orifice 18 continues to operate until the level in the filler pipe 6 is equalized with that in the tank 1. Should the gases above the level 16 subsequently expand due to heat, the orifice 18 relieves such compression to prevent the liquid fuel from being forced up the pipes 6 and 12. Welded to the top wall 3 of the tank is a closed air chamber 17 which communicates with the tank 1 through a hole 15 in the wall 3. The portion of the pipe 12 that has the restricted vent orifice 18 is within the chamber 17. In a modified construction the filler pipe 6 extends into the tank 1 through the top wall 3 and terminates below the maximum fuel level 16. In this instance the restricted vent orifice could be formed in that portion of the filler pipe that is above the fuel level 16 and within the tank 1.

Title: Improvements in or relating to machines for finishing the edges of boot or shoe parts
IPC: A43D95/24
Filed: 1931-12-07
Abstract: 393,615. Boot-making machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. and KEALL, F. B., Union Works, Belgrave Road, Leicester. Dec. 7, 1931, No. 33822. [Class 17 (i).] Edge-setting or like machines for finishing edge portions of bottom parts on boots and shoes have means for varying the extent of oscillation of the tool at the will of the operator during the operation. The mechanism is generally similar to that described in Specification 5355/05, [Class 17, Boots &c.], and is particularly suitable for use in the attachment for setting sole edges at the waist, described in Specification 359,973. Alternative tools may be provided, for the curved and square edges of the waist, the tool holders being rotated to change the tool and locked in the position to which it has been rotated. A driving shaft 1, Fig. 5, has a reduced portion 2 provided with a ball 3 pivotally connected by a pin 6 to a sleeve 7 rotatably mounted in a bearing 4 swivelled as described in the earlier prior Specification. A sleeve 9 slidable along the shaft 2 carries a second ball 8 engaging an inclined portion 12 of the bore of the sleeve 7, a pin 10 passing through the ball and a slot in the shaft. The sleeve is adjustable during operation on a sole by a lever 20 connected to a treadle, adjustable stops 21, 22 determining the limits of movement and therefore the limits of the amplitude of oscillation of the tool, the maximum being approximately 3/16 " when the ball 8 is at the outer end of the sleeve. In a modification, the sleeve 9 carries a pin 63, Fig. 8, to which is pivoted a ring 62 carrying a second pin 61 which passes through lugs at one end of the sleeve 7. The arrangement is that as the sleeve 9 is moved by the treadle the inclination of the sleeve 7 to the shaft 2 is varied, and therefore the amplitude of the oscillation given to the tool. The rack described in the later prior Specification for rotating the tool holder to change the tool, is actuated by a pin 41 on a bell-crank lever 27 Fig. 6, pivoted at 28 and carrying a hand-lever 25 pivoted at 26 and provided with two arms 39, 40 actuating spring plungers moving in bearings 31, 32 secured to the lever 27. Each spring plunger co-operates with a plate 35, 36 respectively, to hold the rack in the position to which it has been last moved. As shown, the rack is locked in its outer position. To reverse the tool-holder the handle 25 is depressed. First, the arm 39 withdraws the latch 29 from the plate 35. The arm 40 then contacts with the bearing 32 to swing the lever 27 anticlockwise, the latch 30 snapping over the edge of the plate 36 when the movement is complete. Lifting of the handle 25 reverses the movements.

Title: Frequency changer
IPC: H02M5/27
Filed: 1960-10-03
Abstract: 891,187. Changing frequency. SIEGLER CORPORATION. Oct. 3, 1960 [Oct. 21, 1959], No. 33825/60. Class 38 (2). An arrangement for converting low frequency polyphase current into single phase current of higher frequency comprises, for each phase a, b, c, of the supply, a pair of silicon controlled rectifiers 16, 17; 18, 19; 20, 21; the rectifiers 16, 18, 20 being connected to one end and the rectifiers 17, 19, 21 being connected to the other end of a centre-tapped primary winding 25 of an output transformer 26 whose secondary winding 31 feeds a load, the centre tap 27 being connected to a neutral point n of the supply. Each pair of rectifiers is operative during the 120 degrees period of the input cycle when the voltage of their supply phase is most positive. During this period the two rectifiers conduct alternately providing an output at the desired frequency, this conduction being controlled through gate electrodes 24 by a control circuit including a control transformer 36, 37, or 38, whose core exhibits a square hysteresis loop and which has a primary winding supplied with a signal at the desired frequency. As shown, the transformers 36, 37, 38 are separate and their primary windings connected in series, but a single transformer may be used. Each transformer core is switched on each signal halfcycle providing outputs in two output windings (say 39 and 40) which are connected to the gates through diodes so that the rectifiers in a pair are pulsed alternately. To prevent the gating pulses being applied to the rectifiers of the non-operative phases, and so avoid deleterious effects, during the periods when the phases are negative with respect to the neutral point blanking pulses are applied to the control transformers through windings 57, 58 and 59 to over-ride the effects of the signal pulses. As shown, the supply phases are derived from a three-phase transformer 15 having zig-zag windings to prevent saturation. Alternatively, the supply may be derived direct from a generator, when rectifying elements may be included in the phase line to reduce excessive inverse voltage across the rectifiers 16 ... 21, and a three-phase zig-zag choke may be included to provide a neutral point in a three-wire supply.
