Title: Improvements in the construction of roofs for dwelling houses
IPC: E04B7/02
Filed: 1925-01-26
Abstract: 248,149. Thomson, R. Jan. 26, 1925. Roofs.-Each of the rafters of the pitched portions of a roof is carried at a point remote from its lower end by a horizontal framework, preferably of cantilever form, which is carried by chimney stacks, party walls, partitions, beams, or other available supports within the building, so that outward thrust on the external walls is avoided and tie-beams may be dispensed with. In semidetached houses, Figs. 1 and 2, the framework consists of four main members 1 - - 4, of which the members 3, 4 act as double-arm contilevers, resting upon a ledge 8 provided on each chimney 5, and strengthened by struts 9 which are supported by channel-iron members 10 carried by the chimneys. Each member 1, 2 is carried by a party wall 7, and the ends of the member 1 are carried by one pair of the cantilever arms 3, 4. and the other member 2 is supported by a partition 11 and carries the longer pair of cantilever arms 3, 4. Joists 12 for the flat part 13 of the roof are carried by the members 1, 2. The rafters 14 of the back and front pitched portions of the roof are hinged to the joists 12 by bolts 16. The rafters 17 of the side pitched portions are notched to engage the members 3, 4, to which they are nailed. Where chimney stacks are not available, the ends of the members 1, 2, which bear upon the party wall 5, may be supported by members borne by partitions. The rafters 14 may be connected by members 22, serving as ceiling joists. All the rafters are bolted or nailed to the framework 1 - - 4. For a detached house, a beam 3, Fig. 5, rests at a point intermediate of its length on a ledge 8 of a chimney stack 5, and its two projecting parts form cantilevers, which are strengthened by struts 9. The beam 3 supports the opposed rafters 14, which are hinged together at their upper ends and may be connected by members 22 serving as ceiling joists. In all cases, the lower ends of the rafters 14 rest upon supports 19 bearing on wall plates 20. The members 1, 2 may be of steel. Specification 216,977, [Class 20 (i), Buildings and structures, Kinds &c. of], is referred to.

Patent GB-868159-A (GB)
Title: Treatment of films formed from highly crystalline polymers of alpha-olefins
IPC: C08J7/14
Filed: 1959-01-23
Abstract: A film formed from a highly crystalline polymer of an alpha-olefin of the general formula: R-CH=CH2, where R is an alkyl, cycloalkyl, cycloalkenyl or aryl group, is contacted with one or more chlorinating, sulphonating or chlorosulphonating agents and any excess agent is removed.  The film may be formed from polypropylene or polybutylene or a mixture thereof, may be pre-stretched in one or more directions if desired, and may be contacted with the agent by passing it through a bath thereof at room temperature.  Specified agents include gaseous chlorine, sulphur dichloride, concentrated sulphuric acid, oleum, phosphosulphonic acid, chlorosulphonic acid and sulphuryl chloride.  The agent may be dissolved in a solvent, e.g. chloroform or dichloro- or trichloro-ethylene, and the film may be contacted with the agent for from 0,5 seconds to 15 mins.  After treatment, the agent is removed by washing with suitable liquids, solvent, if used, having previously been removed by evaporation. The treated film may be aminated by passage through a bath containing an amine in the pure state or in solution, and if the solvent previously used is soluble in the amination bath, the solvent-evaporating step may be omitted.  Suitable amines include isobutylamine, tetramethylenepentamine, mono- or di-ethanolamine, ethylene diamine and ethyleneimine.  After amination, the film is washed and dried. The treatment modifies the film surface by the introduction of polar groups, and so improves the adhesivity of the films to one another and to films of other materials, enabling their use in the production of photographic films (see Group XX), and of laminates (see Group VIII) and tubular sheets.

Title: Improvements in or relating to methods of and machines for sifting nails
IPC: B23Q7/12
Filed: 1919-02-05
Abstract: 142,550. British United Shoe Machinery Co., (United Shoe Machinery Corporation). Feb. 5, 1919. Rotary sieves.-A machine for sifting nails, particularly boot and shoe tacks, comprises a drum rotated progressively in one direction, the movement of rotation being periodically retarded, arrested, or reversed. The driving-shaft 48 carries an arm 50 on the end of which is a pinion 56 engaging an internally-toothed fixed gearwheel 44. The pinion 56 carries a crank 57 having a pin 58 connected by a link 60 with a crank 64 on a shaft 14 which drives the sifting-drum 4 by means of a pinion 16 engaging one or other of two gear-wheels 18, 20 formed at the ends of the drum. In the arrangement shown, the drum first rotates in the forward direction with a speed which diminishes towards the end of the movement, and then rotates for a short distance in the reverse direction, in order that the material which has been carried up during the first movement may fall towards the bottom of the drum and be carried back past the vertical medial plane of the drum. By placing the pin 58 nearer the axis of the pinion 56, the amplitude of the reverse movement may be diminished or reduced to zero, so that the rotation of the drum is intermittently arrested, or its speed is reduced, without actual reversal of the direction of rotation. The drum is mounted on rollers 22, 28 and is provided with gear-wheels at each end, in order that it may be reversed and driven from either end. The nails are fed to the drum from a hopper 8 through a shoot 12 which is vibrated by means of an impact member in the form of a rod 66 carried by the shaft 14. The rod 66 engages a lug 68 on the shoot when the shaft is rotating at its maximum speed, and moves the shoot against the action of a spring 70.

Title: Improvements relating to apparatus for use in the drawing, spinning and twisting of yarns
IPC: D01H1/00
Filed: 1934-01-27
Abstract: 432,639. Drawing, spinning, twisting, and winding yarns. DAWES, F., 11, The Grove, Hipperholme, near Halifax, Yorkshire. Jan. 27, 1934, No. 2844. [Class 120 (ii)] Apparatus for use in drawing, spinning, and twisting yarns, and for winding spun yarn comprises ring or cap spindle apparatus provided with means constituting a support for the yarn during winding adapted to be drawn along the spindle so that the ultimate length of the support is much greater than that at the commencement of winding. The invention is applicable to operations commencing with the two spindle gill box up to and including twisting, excepting single and two-fold weft ; yarn may be spun in this manner and rewound on to spools as required. As shown in Fig. 2, a short reciprocation is imparted to a ring rail 81, and the yarn is wound on a support, constituted as shown in Fig. 19, by a flexible tube 47 which is stored in a collapsed condition in a cap 52 and is drawn down the spindle over the conical portion 45 by means of a sleeve 5. The cap 52 also assists in the rotation of the yarn. A collar 14 carries the sleeve 5 and is lowered by racks and pinions 64, 65 geared with the front roller shaft. As shown in Fig. 22, a reciprocating spindle 55 is provided with a cap operating in the usual manner to twist and wind the yarn. The support may comprise cords 7, Figs. 7 and 8, arranged in grooves in the exterior surface of a hollow rotary spindle 1 and attached at one end to a weight 8 arranged inside the spindle and at the other to the sleeve 5. The grooves are shallow at the part of the spindle where the traverse is effected and deeper at the lower part, so that the cords afford a support for the yarn while it is being wound and are withdrawn from the body of the wound portion. A slotted ferrule 121 is mounted on the spindle to provide a surface for commencing the cop and facilitating its removal. A sleeve may be fitted to extend the cords at the traverse part of the spindle or wires may be arranged in grooves and adapted to be expanded to support the yarn at this part. Spring ribbons coiled around pins at the top of the spindle may be used in place of the cords. As shown in the cap spindle apparatus, the cords 57, Fig. 22, may be endless and' then pass through spaced holes 58 in the hollow spindle 1 and are operated by a collar 14. The rings are secured by clips 83 to the ring rail 81 which is reciprocated by a double heart cam. The cops are doffed by means of mandrels 122 which are mounted in clips 127 carried by a shaft 128 mounted in arms 130 fixed to a shaft 131. The mandrels are positioned over the wound cops which are thereupon raised by the racks 64 and stripped from the spindles and located on the mandrels. By operating the hand-wheel 129 the cops are turned into the dotted line position and may be removed as convenient.
