Patent GB-989027-A (GB)
Title: Process for the manufacture of sections and apparatus for carrying out the process
IPC: B21C37/08
Filed: 1962-07-24
Abstract: 989,027. Making beams and tubes; die-rolling; welding by pressure. VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE A.G. July 24, 1962 [July 28, 1961], No. 28466/62. Headings B3A, B3M and B3R. A process for making sections, e.g. U, trough or angle sections, and tubes from metal strip and of constructions assembled therefrom comprises strain hardening the strip by cold rolling over at least part of its longitudinal and lateral extensions prior to shaping it into the section. Steel strip 32 from a reel 33 travels over a feed roller set 34, past a strip cutter 35 to an end welding machine 36, through an adjustable roll stand 37 to a shape rolling machine 38. The roll stand 37 may comprise a four-high unit of back-up rolls 39, 40 and adjustable ridged rolls 41, 42 which produce corrugations in the strip without any reduction in its width to increase its yield point and tensile strength and decrease its elongation. The strip may be completely or partially, corrugated in transverse, longitudinal or oblique directions or in a combination of said directions. Sections having substantially right-angled corners are formed such that convex and concave curves 10, 9, formed on the sheet form the outer and inner corners respectively of the sections, Figs. 10 and 8 (not shown). A box section, Fig. 9 (not shown), is produced by longitudinally welding two U-shaped members along the untreated zones 11. U -shaped sections are formed from strips 23, 24 having different material thicknesses but identical overall thicknesses by a punch roll 21 and die roll 22. The ends of strips having a common overall thickness may be welded together to facilitate a continuous rollforming process. Sections may be joined at their crests by resistance welding using flat electrodes or if the corrugations of the sections run parallel by interposing a member 29 having transverse corrugations or wire elements between them and applying electrodes 30, 31. Suitable corrugated strips are formed into door frames, Fig. 10; flat tubes for the heat-exchange purposes, Fig. 21, corrugated tubing, structural panels, Fig. 27, and a lattice type guider, Fig. 29, comprising a pair of corrugated open box sections welded to a corrugated zig-zag central member.

Title: Improvements in and relating to moulds for packing for pistons and the like
IPC: B29D99/00
Filed: 1930-09-24
Abstract: 363,416. Dies for moulding piston packings &c. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Dempsey, P. W.; 269, North Dithridge, Pittsburg, U.S.A.) Sept. 24, 1930, No. 28593. Convention date, Dec. 2, 1929. [Class 87 (ii).] Dies for moulding piston and like packings are provided with two co-operating adjacent annular grooves for receiving excess material during the pressing operation, one groove being of relatively small capacity and receiving the excess material in the first instance, and the other of greater capacity to receive the overflow from the first groove, the co-operation between the grooves being such that the resistance to the flow of the excess material increases as the pressing operation proceeds. One of the dies shown in Fig. 1 for making cup-shaped packings is formed with a boss 6 which makes a sliding fit in the orifice 7 of the upper die. The lower die is provided with an annular groove 11 adjacent to the edge of the packing 4 and the upper die is provided with a larger and deeper groove 12, the inner edge of which is in register with the outer edge of the groove 11. The dies are charged with a roughly-shaped packing and then placed in a suitable press. During the closing operation, the space between the registering edges of the two grooves continually diminishes and finally is closed, thus creating an increasing back pressure to the flow of the material. Gas escapes through vent-holes 14 provided at intervals in the groove 12. Fig. 4 shows moulds for making flat packings, two articles being produced at one operation. Two similar moulds, provided with recesses 16 for the packing, are fitted with concentric grooves 18, 19 to receive the excess material. A flat central plate 21 is placed between them, and the whole placed in a press as in the previous case. For small packings, each die may be made to produce a quantity at one operation.

Title: Improvements in or relating to the manufacture of coaxial cables
Inventor: CLARKE GEORGE WILLIAM
IPC: H01B13/20
Filed: 1948-11-04
Abstract: 649,624. Making air-space cables. STANDARD TELEPHONES & CABLES, Ltd. Nov. 4, 1948, No. 28673. [Class 36] A machine for applying helical insulating and spacing members 53, Fig. 9, to the inner conductor 52 of an air-spaced coaxial cable comprises means for feeding a rod or tube of insulating material through a cutting head wherein helices are cut from said rod or tube and mounted on the conductor in spaced relation. The insulating tube 4, Fig. 1, is drawn off a supply drum 1 and passed through guide tube 5, feed unit 6 and guides 9, 10, 13 to the cutting head 12, being hung in a catenary loop between the drum and the cutting head. A roller 14 rests on the lowest part of the loop. As the tube 4 is drawn into the cutting head 12 the roller 14 is pressed upwards and actuates a motor in feed unit 6 which rotates rollers 7, thus drawing a further length of tubing off the drum. The drum 1 and feed unit 6 are continuously rotated at the same speed as the spindle of the cutting head 12 through which the tube passes, thus ensuring that the tube 4 is continuously rotating. This continuous rotation of the drum is independent of the intermittent rotation caused by drawing off the tubing. The rotating tube 4 is fed into the cutting tool 32, Fig. 5, which is carried in the cutting head 12. This tool carries a stationary knife 35 which is so shaped that it draws the tube forward, at the same time making a helical cut therein. A preliminary shallow helical cut may be made by knife 38 which is adjustable to allow for slight variations in the pitch of the helix. The conductor 19 is fed through a housing 41 and bush 42 and its direction of travel forms an acute angle with the direction of travel of the tube 4. The bush 42 is provided with a projection which engages the helix as it emerges from the cutter and guides it around the conductor. When the desired number of turns of the helix have been applied a cut-off knife 51, Fig. 3 (not shown), operates to sever the applied helix 20 from the main body of the insulating tube 4. The applied helix is a tight fit on the conductor 19 and travels forward with the conductor. After the desired length of the conductor has passed the operation is repeated. In the case where the insulating material is in the form of a rod an additional knife is provided to remove the core of the rod as the helices are formed.

Title: Improvements in or relating to holders for pencils or crayons
IPC: B43K29/06
Filed: 1932-10-14
Abstract: 408,028. Pencil &c. sharpeners. KRAUSS, F., 8, Wildpretmarkt, Vienna. Oct. 14, 1932, No. 28783. Convention date, Oct. 17, 1931. [Class 146 (iii).] Relates to pencil and crayon holders of the kind having a conical nose and sharpening-members adapted to be forced inwards to engage the lead within the nose. In the construction shown in Fig. 1, sharpeners 4 are attached inside the conical nose 3 by plate springs 5 and project through slots 2 in the nose so that they can be depressed by hand to engage the lead 6, which is withdrawn into the nose to bring the blunt point between the sharpeners before the latter are depressed. In another construction the nose is slit to provide spring sections, to which the sharpeners are attached. In another construction the plate springs and sharpeners are attached to a ring having a limited sliding movement determined by finger-pieces projecting through slots in the casing ; the springs pass through fixed guides which maintain them in inoperative position. In the construction shown in Fig. 4, the plate springs 5 and sharpeners 4 are carried by a sleeve 17 in which the lead-holder 21 can move, and is attached to a projecting screw-threaded shaft 19 for rotating it to withdraw or advance the lead. When the lead is withdrawn so that the point is between the sharpeners, the shaft 19 carrying the parts 17, 21 is pressed inwards against the action of a spring 22 until the sharpeners contact with the inside of the nose 3 and are thereby forced inwards to engage the lead, which is then rotated by turning the shaft 19. The springs 5 slide through fixed guides 16, which maintain them in inoperative position and serve also to prevent them from rotating while the lead is being rotated between the sharpeners. The Specification as open to inspection under Sect. 91 comprises also a pencil holder recessed at its upper end to receive a cylindrical spring and a conical nose, the nose being adapted to be depressed against the spring whereby sharpeners mounted on plate springs inside the holder are engaged by the conical nose. This subject-matter does not appear in the Specification as accepted.

Title: Method of and apparatus for measuring electromagnetic radiation intensity
IPC: G01J1/16
Filed: 1965-07-09
Abstract: 1,103,416. Photo-electric measurement. WALTER HEIMANN [trading as FORSCHUNGSLABORATORIUM PROF. DR. ING. WALTER HEIMANN]. July 9, 1965 [July 14, 1964], No.29248/65. Heading G1A. A method of measuring the intensity of electromagnetic radiation for example in the determination of temperature changes of glass, involves the use of a mechanical modulator to modulate the radiation at a certain frequency and to produce a reference electrical signal at the same frequency, the difference between the reference electrical signal and the detected radiation signal being indicated. The mechanical modulator is a selfexcited rotary pendulum D having at one end a conventional modulator e.g. a diaphragm or mirror chopper B, to modulate radiation from source O to be measured, and at the other end, means to modulate an amplifier V to produce a reference signal S 4 . In a simple system, the signal S 2  from the detector E passes through narrow band amplifiers V 1 , V 2  tuned to the modulation frequency and mixer M 1  to be combined in mixer M 2  with the amplified reference signal to produce a difference signal which is demodulated by phase sensitive rectifier LJ and indicated at Z. The amplifier A is adjustable to allow balancing of the signals in mixer M 2 . In a system in which the source is measured in association with a reference radiation source which, however, may itself vary, the radiation from this source R is passed alternately with radiation from the measured source O by means of a mirror on the pendulum B, to the detector, to obtain a signal proportional to the difference between the two sources. Variations in the output of source R are measured by comparing signals obtained from the source R with the reference signal S 4  and fed (S 5 ) to the mixer M 1 , so that variations in the measured signal due to variations in the source R are removed.
