Title: Improvements in the bonding of poly-alpha-olefin fibres
Inventor: ERLICH VICTOR LEOPOLD
IPC: D04H1/4258
Filed: 1962-07-04
Abstract: The slippage of fibres in fabrics made from one or more alpha-olefin polymers is prevented and bonded fibres fabrics comprising fibres made from alpha-olefin polymers are made by applying to the fibres a bonding agent comprising an alpha-olefin polymer having a melting or softening point at least 25 DEG C. below that of the polymer of the fibres, heating them at a temperature intermediate that of the melting points of the polymer of the fibres and the bonding agent for a time sufficient to fuse substantially all of the polymer of the bonding agent and to soften or fuse only the surface of the fibres so that the bonding agent becomes sufficiently fluid to enable the the major portion thereof to accumulate at the intercrossings of the fibres and coalesce with the fibre surfaces at the intercrossings and then cooling them to harden the fused and softened portions to form bonds between the fibres at the intercrossings.  The fibres and the bonding agent may be made from polymers formed by the polymerisation of ethylene, propylene, isobutylene, butene or 3-methyl-butene-1. The bonding agent which may be a single polymer, a blend of two or more polymers or a copolymer may be applied to the fabrics as a solution in an organic solvent, e.g. carbon tetrachloride or an aromatic hydrocarbon, as an aqueous dispersion which may contain emulsion stabilizers, e.g. stearic acid or 2-amino-2-methyl-1-propanol, or in dry form as a powder or as cut fibres.  The fabrics may be heated by running them through drying chambers on continuous belts or tenter frames or by running them over heated metal rolls and may subsequently be cooled to below 60 DEG C. by contact with cold air or water.  The fabrics may then be run through a mechanical cleaning device to remove loose particles of dry bonding agent and calendered.  In the manufacture of bonded fibre fabrics the alpha-olefin polymer fibres may be mixed with fibres of cotton, viscose rayon, nylon or acylic resins prior to the application of the bonding agent.

Title: Improvements in or relating to indicators for electric cartridge fuse links
IPC: H01H85/30
Filed: 1938-09-02
Abstract: 517,905. Fusible cut-outs. LAWSON, BECK, Ltd., and BECK, A. J. A. Sept. 2, 1938, No. 25670. [Class 38 (i)] The blowing of a fuse is indicated by the change in appearance of a transparent or translucent tube surrounding the indicating wire in parallel with the fuse, due to volatilisation of this wire. The material and resistance of the wire and the calibre of the tube are therefore chosen so as to ensure the deposition of particles on the walls of the tube when the wire fuses. Fig. 1 shows a cartridge fuse with the auxiliary wire 4 and tube 1 inserted in a groove 2 and sealed by the usual cement for the caps 6. Fig. 3 shows an indicating link wherein the wire 4 is clamped by spade terminals 7 forced into the ends of the tube 1.

Title: Improvements in or relating to heel-attaching machines for use in the manufacture ofboots or shoes
IPC: A43D79/00
Filed: 1920-09-07
Abstract: 150,743. United Shoe Machinery Corporation, (Assignees of Pope, J. H.). Sept. 8, 1919, [Convention date]. Heels, machine for. - In a heel-attaching machine of the type described in Specifications 3314/91, 5084/03, and 2393/15, the nail-drivers are displaced during the loading of the nail block to give clearance for long nails required for high heels. The machine is looked from operation unless the nail block is in alinement with the driver gang, and unless the nail loader is in its receiving position. A sweeping device removes nails improperly lying on the nail block. As shown, the swinging loader-arm carries an upstanding rod 54 engaging a slot 56 on a sleeve 58 having lugs 64 connected by a link 66 to a plate 18 carrying the drivers 20 and sliding in ways 16 on the vertically reciprocating cross-head 14. The plate 18 is therefore slid to the left as the loader block 38 carries nails to the nail block 24. When the loader block reaches delivering position, a tripping projection 50 above the nail block engages a projection 48 on a shutter below the loader block, removing the shutter from a pin 46 and allowing a. spring 52 to withdraw the shutter from beneath the loader block to permit the nails to faill into the openings 22. As the loader block returns, a brush 53 passes over the nail block and removes any nails lying theron. Except in its uppermost position, the slide 18 is locked to the cross-head 14 by a latch-rod 70 having adjusting-nuts 76 engaged by a yoke on a lever 78 pivoted to the crosshead 14. The other end of the lever slides over a rod 80 fixed to the frame, the rod having adjusting nuts 84 at its end. The starting-handle 25 has a link 86 with a collar 90 at its end adapted to be locked against depression and prevent the operation of the machine unless the locks are released. One lock comprises a sliding member 92, Fig. 2, having a projection 98 engaged by a projection 100 on a part swivelling with the loader block 38 when this block is in the position shown. In any other position, the lock 92 engages under the collar 90 and prevents the machine from being started. The nail block 24 slides in ways 26 and when in correct position is locked by a slide 102, Fig. 3. The lock is withdrawn, to enable the block 24 to be changed, by a milled head 110 having a pin 112 which may engage a hole as shown or the surface adjacent the hole to retain the slide 102 out of contact with the block 24. In this latter position a projection 114 moving with the member 102 engages under the collar 90 and prevents the machine being started.

Title: Method for the production of sintered magnesia articles from finely divided magnesium compounds
IPC: C04B35/03
Filed: 1955-09-08
Abstract: Sintered magnesia articles are produced by shaping finely divided magnesia or a finely divided compound of magnesium (other than magnesium sulphate) which decomposes thermally without melting to form magnesia into bodies of the desired form using 6-25 per cent by weight of the total magnesium content calculated as magnesia, of magnesium sulphate as a binder and heating said bodies above the sintering temperature (about 1100 DEG  C.) to decompose the magnesium sulphate.  Specified magnesium compounds are the carbonate, oxide and hydroxide, e.g. magnesite and brucite; a suitable magnesium hydroxide (which may contain sufficient magnesium sulphate) may be prepared by the process of Specification 693,108 or a mixture of oxide and hydroxide may be prepared by treating in aqueous suspension burned dolomite with an equivalent quantity of magnesium chloride and removing the so-formed calcium chloride liquor or a product already containing magnesium sulphate may be obtained by partly decomposing kieserite, e.g. in in a rotary kiln.  The magnesium sulphate may be synthetic or natural, e.g. Epsom salt or kieserite.  The shaped unsintered mixture of magnesium sulphate and other magnesium compound may contain 4-75 per cent by weight of water.  A shaft or rotary kiln may be employed for the sintering, which should preferably be performed at a temperature rising to 1500-1600 DEG  C.

Abstract: 1,117,142. Electric analogue calculating. INDUSTRIAL NUCLEONICS CORPORATION. 18 June, 1965 [19 June, 1964], No. 25949/65. Heading G4G. In a process involving a length of travelling material, a scanning gauge is movable across the width of material to provide a signal having a profile component associated with variations in a characteristic of the material across its width and another component associated with other variations in said characteristic, e.g. along its length, the profile component lying in a range of frequencies substantially unoccupied by the other component, and filtering means passes the profile component to a statistical variance computer. The characteristic is assumed to be the thickness of material. Statistical variance computer.-The variance v of a given component is computed using the relationship by the arrangement shown in Fig. 9. A programmer 100 synchronizes the operation of integrators 62, 76, 94 with the traversing of gauge 50 over one or more scanning cycles. Integrator 94 provides a time-varying output for normalization of the outputs of integrators 62, 76 in dividers 66, 80. The standard deviation # may be obtained from a square-root circuit 90. Separation of components.-The thickness variation comprises the cross-sheet component and machine-direction component, the latter being made up of long-term (low frequency) and short-term (high frequency) components. The long-term, short-term and cross-sheet components are separated by filters 120, 132, 140, Fig. 10 and are fed to respective variance computers, each of which may be identical to that shown in Fig. 9. In this embodiment, the cross-sheet component occupies a higher frequency band than the other components by virtue of a relatively high scanning speed imparted to the gauge. A summing amplifier 130 derives the total variance from the three components, and this value could be compared at 128 with the output of a variance computer receiving all three components. Modifications.-The scanning speed of the gauge may be made very low so that, in an automatic control system in which the longterm component is substantially cancelled by a retroactive servo system, the cross-sheet component occupies a frequency range which would otherwise be occupied by the long-term component.

Abstract: 817,439. Parking meters; coin-freed tiining mechanisms. TELEFONAKTIEBOLAGET L. M. ERICSSON. Aug. 19, 1957 [Aug. 17, 1956], No. 2617/57. Class 27 A coin-actuated timing mechanism in, for example, a parking meter comprises a rotor disc 103 having a radially-displaceable slide 111 with a feeler 221 co-operating with an abutment surface 125 at the end of a coin insertion slot 107 to gauge the diameter of the inserted coin and set the slide so that a pointer 145 indicates the time purchased and a clockwork mechanism is wound by the requisite amount. The rotor 103 carries a three-armed lever 116 and, according to the amount the slide is moved in by a coin, a stop 166 on the slide is disengaged from a shoulder 17 and a spring 120 rotates the lever so that a notch 220 engages either a pin 219 or 218 on the slide to lock it in the position to which it has been set. A projection 117 on another arm of the lever is then set to contact either a stop 126 corresponding to a smaller coin or a stop 127 corresponding to a larger coin and release the locking engagement of the notch 220 with the pins 219 or 218 after the requisite rotation of the disc 103 by an external handle. A pin 130 on the slide 111 engages teeth 132 to 139 on a winding plate 131 to wind the clockwork 160 through gearing 148, 149 and to set the pointer 145 through gearing 150, 151. For successive insertions of smaller coins, the pin 130 can engage alternate teeth 132, 134, 136 and 138 to set the pointer from initial position to full deflection by successive quarter-deflections and, if a smaller coin is inserted when the pointer has been returned by less than an eighth deflection, the teeth 133, 135 and 137 can be picked up. For a large coin, the slide is fully displaced and the pin 130 engages the short tooth 139 to give the full deflection of the pointer. To prevent the disc 103 from being rotated in reverse direction before the slide has been released, a pawl 1136 on the disc can enter recesses 238 in the frame 101a and, by engagement of the other end of the pawl with an arm 119 on the lever 116, turn the lever so as to release the slide. Coins are released from the slide to a passage 129 having a window 156 and collect against a spring 153. until forced past the spring into a collecting box by an arm 155 on the disc 103. A flag 141 is raised on expiry of the parking time by rotation of the wheel 151.

Filed: 1935-09-23
Abstract: 463,247. Vehicle couplings and brakes. TAPP, E. T. J. Sept. 23, 1935, No. 26293. [Class 103 (v)] [Also in Group XXXIV] In an automatic tractortrailer coupling of the kind in which a transverse pin on the tractor is gripped between closing jaws or hooks on the trailer, the relative displacement of fixed and movable jaws l, m respectively is effected by the actual engagement of the cross-pin d<5>, Fig. 1, with the movable jaws m, such engagement also causing the supporting arms j of the trailer to be raised to an inoperative position. In effecting a coupling, rollers d, d<3> on the cross-pin d<5> are guided into the movable jaws m by means of ramp surfaces f<1> formed at forward end of twin levers f constituting the draw-bar on the trailer. A slight raising of the levers f occurs, which relieves the retaining pawls n of the arms j from load prior to their being released from engagement with a ratchet o by the contacting of the cross-pin d<5> with a trip-lever p. The pawls n are carried by twin pivoted levers h which are formed with the jaws m, and which are then free to move upwardly under the weight of the trailer and to retract the jaws m into co-operative relation, Fig. 4, with fixed jaws l on the levers f. In addition, elevation of the levers h causes a striker q to contact with a brake-lever r and release the latter from engagement with a notch s which maintains the brakes in the applied position. The released lever r engages a bracket u on the lever h so that, before an uncoupling can be effected, the brake-lever must be moved forward and re-engaged with the notch s, thereby again applying the trailer brakes. In the coupled position, the trailer brakes may be actuated from the tractor as described in Specification 463,249, [Group XXXIV], that is, by movement in the tractor cross-head a of a plunger v which acts upon the lever p and through it upon the brake-rod w.
