Filed: 1916-10-02
Abstract: 107,702. British Northrop Loom Co., (Northrop Loom Co.). Oct. 2, 1916. Shuttles; shuttles, changing bobbins in, automatically.-In a shuttle of the kind described in Specification 19449/13 for weft-replenishing looms, the bobbin-holding spring A, Fig. 2, the spreader C, and the bobbin-directing guide B are assembled and retained together before insertion in the shuttle, so that they can be inserted as a unit and held in place by the usual bolt D. The spreader C, shown separate in Fig. 6, is inserted between the legs of the shank of the spring so that a hole a therein registers with the holes in the legs, and the guide B, Fig. 5, comprising top and bottom plates e, d connected by an incline c, is placed with its plates over and under the spring and spreader before the top plate is bent, the incline b on the spreader fitting against the inside of the incline c on the guide. The sides f and end g of the guide-plate e are then bent, as shown, to enclose the top of the spring and spreader, and the whole is inserted in the shuttle so that the flanges h and plate d enter grooves therein, as shown in Fig. 4. The bolt D is then inserted and secured in the usual manner.

Title: Improvements in the manufacture of concrete pipes
IPC: B28B21/24
Filed: 1966-03-30
Abstract: 1,136,742. Centrifugally moulding concrete pipes. HUMES Ltd. 30 March, 1966 [2 April, 1965], No. 13989/66. Heading B5A. The internal surface of a centrifugally formed concrete pipe is smoothed by rotating a smoothing roller in contact therewith at a peripheral speed greater than that of the pipe. A horizontally disposed mould (10) with end plates (12), (13) is rotated by a motor (14). Concrete mix is fed into the mould and it is compacted by a longitudinally extending and centrally offset smoothing roller (15) running freely at the same speed as the mould wall. When compaction of the pipe is nearly complete, the roller is rotated at an increased speed by a motor (16). Pressure is applied to the pipe by means of hydraulic rams (17) on which the roller (15) is mounted. The roller, of any appropriate diameter and material, may extend only part way through the pipe and may also be freely supported under gravity.

Filed: 1925-06-04
Abstract: 235,198. Nier & Ehmer. June 5, 1924, [Convention date]. Lantern doors and door fittings. -In a vehicle lamp the rim e carrying the front glass g is secured to the sheet-metal paraboloidal body a by means of a stiff edge on one part engaging over one or more resilient curved segments on the other part. The internal diameter of the stiff edge is slightly less than the maximum diameter of the segments, and the part carrying the segments also has a shoulder m so placed that it arrests the stiff edge intermediate the swell of the segments and their points of attachment. With the construction shown in Fig. 1 the rolled edge k of the rim e is engaged over a shallow hook n, and is then pushed over a diametrically opposite curved segment o. The radius of curvature of the edge is approximately equal to that of the hook n, but is somewhat less than that of the segment o. In the form shown in Fig. 5 the hook n is dispensed with and the whole circumference of the body a is provided with a curved member p preferably divided into segments p<1>, p<2>, p<3> by cuts q. The curved segments may be formed integrally with the lamp body. For removal, the rim e may be forced over the curved segments by turning a suitable key in a slot r, Fig. 6, cut either in the rim a or in the shoulder m, or by turning a segmental device u, Fjg. 9, pivotally mounted on the body a and adapted to pass through a slot x cut in the shoulder m.

Filed: 1937-05-25
Abstract: A cast compound roll having a shell of unalloyed or alloyed white or grey cast-iron with a shore hardness of 45-100 DEG  is formed with a core of an alloyed or unalloyed steel having a carbon content of from 0,5-2,0 per cent.  In an example, the core contains approximately 0,55 per cent carbon, 0,8 per cent manganese, 0,25 per cent silicon, 0,06 per cent phosphorus, and 0,05 per cent sulphur, and the chilled cast-iron shell contains approximately 3,5 per cent carbon, 3,5 per cent manganese, 3,0 per cent nickel, and 1,5 per cent chromium. Other elements such as nickel, chromium, vanadium, and molybdenum may be present in the core.  The casting temperature of the steel approaches the melting temperature of the cast-iron shell sufficiently closely to avoid melting of the latter when the core is cast on to it.

Title: Improvements in or relating to pest control compositions
IPC: C07C23/12
Filed: 1943-09-08
Abstract: A pest control composition consists of an aliphatic hydrocarbon boiling in the kerosene range, i.e., 150-360 DEG  C., or a mixture of such hydrocarbons, having dissolved therein at least one isomeric form of benzene hexachloride, other than b  benzene hexachloride. A pure aliphatic hydrocarbon such as decane or undecane, or a mixture of aliphatic hydrocarbons boiling within the specified range and derived from petroleum or by a coal distillation process, may be used.  Crude benzene hexachloride, obtained, for example, by chlorinating benzene at 50 DEG  C. while exposed to sunlight or the light of a mercury arc lamp, may be employed; or the crude product may be treated to separate a substantial proportion of the a  isomer, e.g., by fractional crystallisation or filtration, or of the g isomer by preferential extraction after evaporation of the unchanged benzene, the product containing the g  isomer being used to prepare the compositions.  It is also possible to use the a  isomer.  The compositions may also contain other additions such as pyrethrum extract sesame oil, or the solvent used in extracting the g  isomer, e.g., xylene or a chlorinated aliphatic hydrocarbon.  Specifications 573,689, 573,693, 586,439 and 586,442 [all in Group IV], are referred to.

A process for increasing the molecular weight of polyesters comprises heating a polyester produced by reacting a polyol or glycol with a 6- hydroxycaproic acid or an alkyl ester thereof or with an epsilon-caprolactone, at 150 to 300 C., in the presence of an ester interchange catalyst while continuously removing polyol or glycol from the reaction mixture. The 6-hydroxycaproic acid or epsilon-caprolactone may be substituted by C 1-6  alkyl, and the polyol is preferably ethylene glycol, diethylene glycol, dipropylene glycol, 1,3-propanediol, 1,4-butanediol, 1,5-pentanediol or 1,6-hexanediol. The catalyst may be one or more of alkoxides and acylates of titanium, zirconium, aluminium, zinc, cadmium, magnesium, tin, lead and antimony, organic tin compounds, zinc borate, lead borate, antimony trioxide and litharge, the concentration of catalyst preferably being from 5 p.p.m. to 0À5% by weight. The polyol or glycol may be removed by conducting the process under pressure, preferably from 300 to 1 mm. Hg, or in a stream of inert gas, preferably nitrogen. The polyesters prepared by the process of the invention may be converted to polyurethanes by reaction with isocyanates.

Abstract: 659,010. Two-stage hydraulic pumps. INTEGRAL, Ltd., WESTBURY, F., BRAY, P. E., and PACKENHAM, E. W. June 2, 1949, No. 14837. [Class 102(i)] [Also in Group XXIX] A two-stage hydraulic pump comprises two pumping units in tandem, the second stage unit being a radial cylinder pump whose pistons 23 are operated on their working strokes by a cam on eccentric 24 with which they are held in contact only by the liquid supplied by the first stage unit, and an off-loading valve 46, (see Group XXIX), subjected to the final delivery pressure and controlling the latter automatically by relieving the first stage pressure back to the inlet and thereby rendering inoperative one or more pistons of the second stage unit at a predetermined delivery pressure whilst permitting the other pistons to operate at full stroke. When the delivery pressure exceeds a maximum value the valve cuts off communication between the first and second stages and delivery ceases. Liquid enters the pump at 15 and is delivered by a gear pump 12, 13 to an annular duct 21 communicating through inlet valves 22 with the cylinders 27. The liquid is delivered through valves 28 to an annular duct 30 communicating with an outlet 33. In one embodiment the inlet valves of one or more pistons are loaded by stronger springs than the other pistons so that they cannot open when the first stage delivery pressure is reduced. In another embodiment, the valve controls two or more ports leading to different groups of cylinders and the ports are closed successively as the delivery pressure rises. Specification 582,182 is referred to.
