Abstract: 245,201. Fiddes, J. Oct. 2, 1921. Corrugating. - In a machine for corrugating barrel and like hoops, preferably after bending and joining the ends, of the type comprising a pair of positively driven parallel spindles carrying rolls at their ends and adjusted towards each other without affecting their parallel relationship, one of the spindles is mounted in a pivoted frame adjusted in one or both directions by hydraulic means. The hoop s is placed against guide rollers t on a table and between the corrugating-rolls a, b, the shaft d of the roller b of which is mounted in a frame f moved inwards about its pivot g by an hydraulic ram k. The frame may be withdrawn on release of the pressure operating the ram k by a spring or weight or by a small ram connected to the frame by a lever and link and communicating with an accumulator continuously supplied with pressure from a pump driven by the main shaft, or from an external source. The supply to the main ram mav be controlled by a hand-operated valve m. Both rams may be controlled by the valve m and arranged so that when pressure is admitted to one it is cut off from the other. The roll spindles are connected by toothed wheels having deep teeth.

Abstract: 155,053. Henderson, J. B. Sept. 22, 1919. Gyroscopic apparatus. - In order to stabilize the field of view of an optical instrument, such as a camera, mounted on an oscillating platform, such as an aeroplane, the light is directed into the instrument by a mirror carried by a frame which is so mounted between the oscillating platform and a stabilizer that it oscillates through half the angle of swing of the platform. A gyroscope 5, having a vertical axis, is pendulously mounted on horizontal pivots 6, 7 in a ring 2 which is mounted on horizontal pivots 3, 4 in a support 1 secured to the aeroplane &c. The mirror 27 for directing light into the camera &c. 29 is carried by an L-shaped frame 9, the corner of which is connected by a universal joint 10 to the ring 2. One end 9<a> of the frame rests on a roller 11, Fig. 2, carried by an arm 12 which is pivoted on bearings 13, 14 in a housing 15 secured to the gyro-casing. The other end 9<b> of the frame rests on a roller 16, Fig. 3, carried by an arm 17 which is pivoted in a housing 20 carried by an arm 21 to which is secured a sleeve 22 mounted on a boss 23 on the frame 1 co-axial with the pivot 3. The axes 6, 7 and 3, 4 respectively bisect the lines 10, 11 and 10, 16. The position of the crank 21 can be adjusted by a screw 24 engaging the lug 26. The frame 9 carries two further mirrors 30, 32 inclined at 45 degrees so as to furnish views of the horizons parallel to the axes 3, 4 and 6, 7 respectively to observers looking through the vertical telescopes 36, 34 secured to the support 1. These telescopes are used to detect precession of the gyroscope, which can be corrected by adjusting the screw 24 or by vertical adjustment of the pivot 4, the pivot bearing being secured to a vertical screw 40 engaging with an adjusting-nut 43. The telescopes 34, 36 may be arranged so as to be used simultaneously by the two eyes of an observer, or their fields of view may be combined in a single eyepiece.

Patent GB-443098-A (GB)
Title: Improvements in or relating to the production of knitted fabrics
IPC: D04B15/00
Filed: 1934-08-15
Abstract: 443,098. Knitting. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and BOALER, W. H., c/o British Celanese, Ltd., Spondon, near Derby. Aug. 15, 1934, No. 23488. [Class 74 (ii)] A circular knitting - machine for producing non-laddering fabric as shown in Fig. 6, is provided with a series of transfer points, which are caused to enter, in succession, loops which have been drawn down by the needles, and stretch them over the heads of adjacent needles, before these adjacent needles are caused to rise again. Transfer points 48 which may have loop-holding notches 111, are mounted in a point cylinder 49 pivoted eccentrically with respect to the needle cylinder, and are lowered by point cams 61, acting on butts 60, to cause them to enter the loops drawn by the needles. The point cylinder rotates in the same direction as, and with a peripheral speed somewhat greater than, the needle cylinder, and when each point has overtaken its needle to the extent of 1¢ needle spaces, it has (by reason of the smaller diameter and eccentricity of the point cylinder, or under the action of a cam 80) moved out to a position between two needles instead of behind them. The needles now rise to pass through the stretched-out loops, so that each loop lies around two adjacent needles. The transfer points are now raised out of the loops by the point cams. Thus, in the next course, each needle draws one loop through two old loops. Fig. 22 shows the path taken by the transfer points when operated by the cam 80. The points rock on a curved edge 83 of their butts 60. A clutch 39, carried by a rod 40, may engage with either of gears 35, 38, to drive the machine in either direction. Movement of the rod 40 to the left, as when starting reciprocatory knitting, actuates a rod 95. This first operates to lift the transfer point depressor cam, and then, after an interval, (determined by a lost motion device), so that any points already depressed will be raised, the whole transfer point assembly is rocked towards the centre of the needle cylinder, about bearings 91, so removing the points from the needles. By rendering the transfer points inoperative, horizontal stripes may be produced. Certain transfer points may be omitted or rendered inoperative (e.g. by selective patterning mechanism) to produce a recurring pattern, in which case at least one loop in every wale should be transferred in each pattern repeat. The spacing of the transfer points may be greater than that of the needles, to produce a more open fabric. The loop transfer may be to preceding adjacent needles, the peripheral speed of the point cylinder being less than that of the needle cylinder. In the Provisional Specification, yarn feeders, and associated point cylinders, are said to rotate bodily around the needle cylinder of a multi-feeder machine.

Abstract: 1,017,556. Packages. KODAK Ltd; May 29, 1964 [June 13, 1963], No. 23547/63. Heading B8C. [Also in Division H5] A sheet of X-ray film is packaged between two sheets of light-impervious paper, a tape coated with a heat-sealing adhesive being heated and applied to the four package edges. Alternatively, the film may be placed inside a folded sheet and the tape applied to the three open edges. The tape extends beyond the package corners and may have a rip-strip incorporated in the extension. In a further embodiment, a strip of X-ray film is fed between two webs of light-impervious paper, heat-sealing adhesive tape being drawn from two reels to seal adjacent edges of the webs. The tube thus formed may be cut into lengths and the transverse edges similarly sealed; or the strip package may be rolled on the reel. An adhesive activated by applying a solvent or plasticizer may be used in place of a heat-sealing adhesive, but in either case the adhesive is of the delayedsetting type. The seam of the package in roll form may be opened either by tearing apart the outer webs, or by pulling a rip-strip in the fold of the edge-binding tape. One, or a pair, of intensifying screens may be included or formed on the interior of the packaging material.

Title: Improvements in and relating to a regulating arrangement for grid controlled electric discharge vessels
IPC: G05F1/42
Filed: 1934-08-16
Abstract: 429,140. Converting. SIEMENS-SCHUCKERTWERKE AKT. - GES., Siemensstadt, Berlin. Aug. 16, 1934, No. 23691. Convention date, Nov. 9, 1933. [Class 38 (ii)] In arrangements comprising a number of grid-controlled discharge devices such as mercury arc rectifiers 5 connected to a common supply network 4 and feeding either a common load circuit or a number of independent load circuits 1, provision is made for simultaneous regulation by a common control element and also for independent regulation of the individual rectifiers. In the arrangement shown, ignition impulses are distributed to the grids of the several rectifiers through rotary distributers 6, the rotary elements of which are mounted on a common shaft driven by a synchronous motor 8. Simultaneous regulation of the several rectifiers may be effected by angular displacement of the field of the synchronous motor by adjustment of the relative magnitudes of two field components provided by the windings 9, 10. Alternatively, this regulation may be effected by phase shifting devices (transformers or variably saturated chokes) provided in the A.C. supply to the motor. Independent regulation of the several rectifiers is effected by angular displacement of the non-rotary elements of the distributers 6 by separately controlled motors 7. Synchronous generators may, however, be substituted for the rotary distributers 6, in which case independent regulation of the several rectifiers may be effected by angular displacement of the generator fields by relative adjustment of two components as in case of the motor field for effecting simultaneous regulation. In alternative arrangements, (not illustrated), non- rotating grid control apparatus is employed. For example a group of phase-shifting transformers having their rotors mechanically coupled may be employed for simultaneous regulation, a further group of phase-shifting transformers with independently adjustable rotors being employed for independent regulation. Specifications 406,913, 413,797, and 416,021 are referred to.
