Title: Crimping filamentary material
IPC: D02G1/12
Filed: 1963-07-03
Abstract: 1,047,166. Crimping yarns and fibres. CELANESE CORPORATION OF AMERICA. July 3, 1963 [July 3, 1962], No. 26348/63. Heading D1F. [Also in Divisions A2 and B5] A filamentary strand is crimped by continuously forcing a filamentary strand by frictional engagement with a continuously rotating surface 13 into a zone constricted in the direction of the strand thickness against an impedance at the exit from said zone afforded by frictional engagement with a second such surface 15, surface 13 moving at a speed greater by a predetermined amount surface 15, the path of the strand in the zone being inclined to the line of centres of the rotating surfaces. The filamentary strand may be a yarn, tow, sliver, or roving, of cellulose triacetate, secondary cellulose acetate, nylon, a polyester, a nitrile, an acrylic, or a vinylidene polymer or copolymer. The crimping chamber is formed by plates 14,16 supported between rolls 13, 15 in slits in side plates. Plate 16 has a piston-cylinder, mounted (Fig. 3 (not shown)), for easy removable into a retracted position while the positions of both plates may be adjusted by bolts. Rolls 13, 15 are preferably rubber covered, but they may have a rigid surface in which case they should be spring mounted. Alternatively the crimping chamber may be formed by roll 15 and plate 16. In one example a tow of cellulose triacetate filaments from a wet spinning column (see Division B5) is pretreated by, for example, steam and is then crimped. The crimped tow is set by saturated steam at 212-300‹F., is opened by rolls, with the lower rolls smooth and the upper rolls helically grooved, and stapled. The staple fibres are formed into a yarn which, on passing through boiling water, is formed into a bulky product. Alternatively, to form cigarette filters (see Division A2), the opened tow may be plasticized with 7% of its weight of glycerol triacetate, and condensed into a narrow bundle which is wrapped in paper and cut into plugs. It is stated that by using this crimping apparatus yarn having 50 crimps/inch and tow having 25 crimps/inch may be obtained.

Abstract: 1,193,612. Concentrating solutions by freezing. STRUTHERS SCIENTIFIC & INTERNATIONAL CORP. 1 June, 1967 [14 June, 1966], No. 26379/66. Heading B1G. In a process for concentrating a solution by crystallization, the crystal/solution slurry from a crystallizer is filtered to increase the crystal concentration prior to a further separation in a centrifuge or after initial separation in a centrifuge. As illustrated, beer or coffee solution is passed to a refrigerated crystallizer 51 and the resultant ice/solution slurry is passed through a filter 53 to a centrifuge 56. Ice is removed via a line 64 and solution from the filter and centrifuge is passed to a further crystallizer 58 and filter 60 when product solution is removed via a line 61 and ice crystals are passed to a tank 48 to join feed solution. Water used to wash the ice crystals in the centrifuge also joins the feed solution via a line 63. In another embodiment, Fig. 1 (not shown), the second crystallizer and filter are not present. In a still further embodiment, a centrifuge is arranged immediately downstream of the first crystalliser and a filter is arranged downstream of the second crystalliser.

Title: A method and device for counting courses in knitted fabric
IPC: D04B35/00
Filed: 1955-09-15
Abstract: 782,784. Testing fabrics. MARVEL SPECIALTY CO. Sept. 15, 1955 [Oct. 22, 1954], No. 26386/55. Class 42 (2). [Also in Groups XIX and XXXVII] The loop courses in knitted fabric are counted by extending the fabric to a tension whereat the intertwined end portions of side-by-side yarn course loops are extended into a series of parallel course-defining ridges on one side of the fabric, and passing a ridge-impulse course-counting mechanism across and in contact with the ridges. Fabric tensioning. As shown, Fig. 1, the fabric 10 to be examined is placed across rubber-. faced rollers 8, 9 and is held against roller 8 by a spring loaded roller 14 while roller 9 is manually turned clockwise to tension the fabric. Roller 9 is held against reverse rotation by a ratchet and pawl mechanism. Roller 8 is carried by a sleeve loose on a shaft 3 but is restrained from rotation by a spring 23 acting on a lever 11 fixed to the sleeve. When the fabric tension is such that the loops are extended to the desired extent without the yarns being stretched, it causes lever 11 to move sufficiently to close a switch 12 while a second arm 21 of lever 11 depresses a pawl 20 to lock roller 9 against further forward rotation. Course counting. Closure of switch 12 starts an electric motor driving a crank shaft 39 which, through a crank pin 41 and slotted lever 42, reciprocates a casing 28 along a plate 26 beneath the fabric 10. A nipple 30 projecting from casing 28 cortacts the fabric and successive course ridges on the lower surface of the fabric enter a cross groove in the nipple face and depress a plunger 35, Fig. 7, each pulsation of plunger 35 breaking contacts 33, 34 in a circuit 63. The pulses in circuit 63 are used to operate a counting mechanism. A disc on shaft 39 has a conducting segment which, together with a cooperating brush, is placed in circuit 63 and operates to transmit pulses to the counting mechanism only when the casing is moving from left to right, Fig. 1. At each break in circuit 63, a solenoid 54, Fig. 8, is de-energized to allow a spring-loaded pawl 53 to advance a ratchet wheel 51 by an amount determined by an adjustable stop 56. Ratchet wheel 51 is mounted on a shaft 49 which also carries a pointer indicating the total count on a dial on the top of the casing 2, Fig. 1. During return movement of casing 28, a sector-shaped plate 59, Fig. 5, on shaft 39 engages a disc 60 on the pointer shaft 49 and rotates it until a flat 61 on the disc reaches the dotted line position when the pointer will have been zeroized ready for the next count.

Title: Method for manufacturing diodes
IPC: H01L21/223
Filed: 1961-07-21
Abstract: 921,864. Semi-conductor rectifiers. HOFFMAN ELECTRONICS CORPORATION. July 21, 1961 [Aug. 3, 1960], No. 26595/61. Class 37. In a method of making a diffused junction silicon diode having a very low Zener breakdown voltage, impurities are diffused in the gaseous state into the silicon crystal, the crystal then being annealed (i.e. cooled) after which the crystal is reheated and again allowed to cool. It is stated that a diffused junction diode has generally more satisfactory properties than alloyed junction diodes and that the step of reheating and cooling gives such a diode a Zener voltage of the same order as an alloyed junction type. It is also suggested that the mechanism involved is one in which impurity atoms occupying interstitial positions in the crystal lattice are moved to substitutive positions during the reheating. Slices of boron doped silicon 14 are placed in a furnace 12 which is maintained at a temperature of 1250‹ C. Phosphorus pentoxide is placed in a crucible 15 and is evaporated at a temperature of 600‹ C., the gas being carried into furnace 12 by a carrier gas, such as nitrogen, which is pumped through tube 16 at a rate of one litre per minute. After about an hour when a surface concentration of phosphorus of 10<SP>21</SP> atoms per cubic centimetre has been obtained on the silicon slices, the latter are transferred to a chamber 13 initially at 1000‹ C. The furnace is switched off and the silicon slices are removed when the temperature drops to 200 ‹ C. The slices are then placed in another furnace at a temperature of 1250‹ C. for 20-30 minutes after which the temperature is allowed to drop to 200‹ C., the slices then being removed. Figs. 3 and 4 show the effect of re-annealing on a typical silicon diode, t 0  representing the optimum time for maintaining the second furnace at 1250‹ C. and Vz 2  representing the low Zener voltage achieved using this method. For a fourteen mils. thick slice of silicon which is doped with phosphorus so as to have a resistivity of about 0.003 ohm cm., this time t 0  is about 25 minutes. After re-annealing the silicon slices are sand-blasted or lapped to remove the phosphorus layer and are then plated with nickel and also possibly gold. The slices may be cut into smaller units which are then encapsulated to make Zener diodes, or they may be combined with other units e.g. a similar diode connected in the inverse sense, the combination forming a temperature-compensated Zener diode. Specification 907,120 is referred to.

Title: Improvements in or relating to pneumatic tyres
Inventor: FLETCHER HENRY RAYMOND
IPC: B60B3/00
Filed: 1962-07-11
Abstract: 1,045,486. Mudguards for vehicle tyres. DUNLOP RUBBER CO. Ltd. June 26, 1963 [July 11, 1962; Oct. 12, 1962; May 25, 1963], Nos. 26607/62, 38704/62 and 20978/63. Heading B7C. A pneumatic tyre is provided with a waterdeflecting annulus 1 which is attached by one edge of a side wall of the tyre, as in Fig. 3 or 4 (not shown), or held between a bead of the tyre and a wheel rim flange 9, as in Fig. 1, the annulus being in contact or in close relationship with the tyre side wall when the tyre is not under load, and the unattached portion thereof being movable axially outwardly to a waterdeflecting position during rotation of the loaded tyre. The annulus 1 is constructed from two layers 2, 3 of rubberized parallel steel cord fabric and a rubber ring 6 which is sandwiched between the radially inner edges of the layers 2, 3 so that it is positioned between the tyre and the wheel rim flange 9 when mounted on a tyre and wheel assembly. The free edge of the annulus is stiffened by an inextensible bead 4. During rotation of the tyre under load, the ground-contacting tread portion of the tyre is forced radially inwards, resulting in axially outward deflection of the adjacent portions of the side walls radially inward of the ground-contacting tread portion and subsequent flattening of an adjacent portion of the ring 6. As the annulus is substantially inextensible in a radial direction, this distortion of the ring 6 causes that portion of the annulus in the region of the ground-contacting tread portion to be deflected axially outwardly from the tyre side wall into the waterdeflecting position shown in dotted lines in Fig. 1. In a modification the ring 6 may be replaced by a bead of rubberized convolutions of wire arranged radially outwardly of one another, while the annulus 1 may be shaped to conform with the radially outer peripheral surface of the rim flange 9 before it extends along the tyre side wall. In further modifications, the layers of the annulus are formed from a single length of fabric and the stiffening bead 4 may be replaced by an annular inflatable tube which is reinforced with two plies of parallel cords and vulcanized so that when uninflated it is folded back upon the annulus and projects towards the radially inner edge thereof. In the embodiments of Figs. 3 and 4 (not shown), one edge of the annulus 1 is vulcanized to a side wall of the tyre in such a radial position that as the tyre is distorted under load, that portion of the annulus adjacent the groundcontacting portion of the tread moves axially outwards into its water-deflecting position as shown in dotted lines.

Abstract: 889,306. Battery charging systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 19, 1958 [Aug. 22, 1957], No. 26641/58. Class 38 (4). A battery charging apparatus operable from a number of different A.C. or D.C. voltage sources has a comparison device to connect the source to the battery only when the supply and battery voltages are in correct relationship. A transformer 2 primary winding is connected by a voltage-selecting switch SI-SVI to a source 6, to which is also connected a bridge rectifier 8 supplied through a capacitor 22 which operates a relay W on A.C. supplies, the relay being protected by a shunt connected voltage dependent resistor 23. Operation of relay W disconnects through a contact w1 a vibrator unit 1 whose driving coils 4, 5 may be connected in series or parallel. A polarized relay P has a coil 16 connected to the source through a rectifier 15 and one of resistors 9-11, and an opposing coil 17 connected to the battery 7 so that when the currents to the windings are similar, a contact p operates through a transistor 20 a relay A, whose contacts al, a2 connect the transformer 2 to the source, and the battery 7 to a rectifier 3 fed from the transformer secondary winding respectively. A capacitor 25 and choke 26 smooth the rectifier 3 output. The relay P only operates when the source voltage and battery voltage are in correct relationship, hence neither of these voltages need be known, also when the battery voltage rises or falls beyond determined values it is also disconnected.

Abstract: 784,127. Acoustic delay lines. ELLIOTT BROS. (LONDON), Ltd. Oct. 26, 1953 [Oct. 24, 1952], No. 26800/52. Class 40 (8). [Also in Group XIX] Apparatus for generating coded trains of electric pulses, e.g. for an electronic digital computer, comprises a length of thin wire, tape or the like of material having an appreciable magnetostriction, input circuits each electromagnetically coupled to one of a number of parts along the wire &c. which parts are spaced apart by distances determined by the product of the time spacing between successive pulse positions in the trains to be produced and the velocity of propagation of acoustic pulses in the magnetostrictive material, means for simultaneously passing a current pulse through one or more selected input circuits, and an output circuit electromagnetically coupled to a further part of the wire &c. which is spaced from an endmost one of the number of parts. As shown, input coils 7 are selectively connected by switches 8 to pulse input terminals 9, so that in response to a pulse 10, a binary number may be generated, in the form of a series-mode pulse train (pulse for " 1," no pulse for " 0 "), in the nickel wire 1 and in the output coil 3 which is connected through pulse-shaping and amplifying circuits 6 both to output terminals 12 and to an input coil 2 coupled to the wire, whereby a closed loop delay line store is formed. Those switches 8 not connected to coils 7 are connected to dummy coils 7a associated with a line 1a thus maintaining a constant load in the input circuits. The portions of wire 1 coupled to coils 2 and 3 may have a standing magnetization produced by e.g. permanent magnets such as 13, solenoids or remanent magnetization in the wire itself. The functions of coil 2 may be performed by the leftmost coil 7. The ends of the wire are received in reflection-suppressing sleeves 4 filled with grease. In a modification (Fig. 2, not shown), the switches 8 connect the coils 7 in parallel to terminals 9. Specification 780,005, [Group XIX], is referred to.

Abstract: 1,140,183. Separating hydrocarbons. TEXACO DEVELOPMENT CORP. 13 June, 1967 [28 June, 1966], No. 27170/67. Heading C5E. [Also in Division B1] C 10-24 -straight chain hydrocarbons are isothermally separated in the vapour phase from mixtures thereof with branched chain hydrocarbons by selective adsorption on a molecular sieve, preferably of Type 5A, the adsorbed straight chain hydrocarbons being subsequently desorbed in two stages, firstly with at least one straight chain hydrocarbon having an average number of carbon atoms in the molecule in the range exhibited by the five lowest components of the feed, and secondly with a straight chain hydrocarbon having an average of 1-4 carbon atoms less in the molecule than are present either in the lowest component of the feed or in the first desorbing medium. As shown, a vaporized mixture of fresh feed and purge recycle is charged by line 3 to adsorbent vessel 30 containing a Type 5A calcium sodium aluminosilicate molecular sieve, the effluent mixture of light desorbent displaced (from the previous cycle second stage desorption) and unadsorbed branched chain hydrocarbons passing by line 5 to fractionator 35, separated light desorbent passing by line 20 and line 7 to subsequent stages. When the adsorption stage is complete, the vessel 30a is depressured by venting through line 9, and vessel 50a is then purged in counterflow with light desorbent introduced by line 8 to remove surface adsorbed hydrocarbons, purge effluent being recycled by lines 9 and 2 with feed. After purging, vessel 30b is repressured and heavy desorbent fed in counterflow by line 10, effluent leaving by line 13 to fractionator 50 where the required straight chain hydrocarbons are recovered as the bottom product by line 24, and heavy and light desorbent fractions are recycled by lines 25 and 23 respectively. Thereafter, light desorbent is passed by lines 7 and 6 in counterflow into vessel 30c, effluent from which is passed together with light desorbent from line 23 by line 27 to fractionator 45, where it is separated into light and heavy desorbents, both of which are then returned to the process by lines 21 and 22 respectively. Vessels 30, 30a, 30b and 30c may be separate vessels operated through successive stages, or may comprise one vessel worked cyclically. The process is suitably performed at 575-700‹ F., the adsorption stage at 5-80 p.s.i.g., and the desorption stages at 1-20 p.s.i.g. above the highest adsorption pressure. When the feed is kerosene and/or gas oil, the heavy desorbent is suitably n-decane and the light desorbent n-heptane or n-octane.
