Abstract: 990,321. Corrugating. TREFIMETAUX. Dec. 10, 1963 [Dec. 13, 1962], No. 48779/63. Heading B3E. A machine for corrugating metallic tubes, e.g. aluminium sheaths of electric cables, comprises a rotary tool holder through which the tube to be corrugated is passed axially and is characterized in that the holder is fitted with at least one corrugating member consisting of a rod extending radially through the holder into the bore thereof which carries at its inner extremity a projecting rotary ball and a device for regulating the depth of the ball within the holder. The machine comprises a frame 1 in which is rotatably mounted a sleeve 2, driven via a pinion 4, to one end of which is keyed and screwed a tool-holder 5 having a hard plastic flanged bush 9. Four screwed rods 15, in the end of which are located and retained superposed balls 17, 18, are located in tapped radial holes 13a-13d and extend through aligned holes in the bush 9 which is an interference fit in the holder 5. The holes 13a-13c are angularly spaced within an angle of 90 degrees whilst the fourth hole 13d is further angularly displaced from the preceding hole, all of the holes being positioned along a helical path. A second set of similarly arranged holes 14a-14d are provided for producing corrugations of a different helical pitch. Vernier type adjustment of each of the rods is effected via a graduated scale marked on a flattened portion thereof in conjunction with a graduated chamfer about the tapped holes 13. The leading ball 17 is of a larger diameter than the succeeding ones which may also vary in diameter. With the tool-holder 5 rotating, the rods 15 being so adjusted that the forming balls 17 produce a progressive increase in the depth of corrugating, a tube 30 is initially axially moved into contact with the balls which corrugate the outer wall thereof. The tube is subsequently drawn through the tool by the action of the tool thereon, the tube being backed up by the portion of the bushing opposite to the balls. In an example the tool-holder speed is 800 r.p.m., the corrugation depth and pitch 3.2 mm. and 14 mm. respectively, the initial and final tube diameter 38.3 mm. and 37.2 mm. respectively, a nd the tube feed rate 1.12 metres per minute.

Title: Production and purification of bisphenol-a
IPC: C07C39/16
Filed: 1963-12-12
Abstract: A process for working-up crude bisphenol-A (2,2 - (4,41 - dihydroxydiphenyl)propane), prepared by condensing phenol with propadiene, propyne or mixtures thereof in the presence of a Friedel-Crafts or Lewis acid catalyst, includes the steps of (1) distilling the crude product to separate more volatile materials, (2) vacuum-distilling the residue to obtain a distillate of bisphenol-A and resinous by-products and (3) separating the bisphenol-A from the by-products by treatment with a solvent for the by-products, the solvents being benzene, toluene, xylene or a chlorinated aliphatic hydrocarbon.  The resinous by-products, after separation from the bisphenol-A, may be recycled for use in the preparation of more bisphenol-A, if desired after a preliminary treatment with phenol and boron trifluoride or hydrogen chloride.  An example is given.
Patent GB-492270-A (GB)
Abstract: 492,270. Automatic control systems. ELECTROFLO METERS CO., Ltd. (Republic Flow Meters, Inc.) March 15, 1937, No. 7495. [Class 38 (iv)] Fluid pressure &c.-A normally balanced member, such as a lever, subject to a condition to be controlled, selectively engages one of two sets of contacts in sequence according to the direction of its displacement from a normal position, and not until a relatively remote contact is engaged are the circuits which these contacts control brought into operation; when this occurs, a relay closes auxiliary circuits initiating the desired action of an electric motor and actuates means for closing a holding circuit which is maintained until all contacts have been disengaged by the reverse movement of the lever. One of the auxiliary circuits may energize a magnet tending to restore the lever to its normal position in advance of the correction of the controlled condition. The Figure shows a regulator according to Specification 463,549, [Group XXIX], adapted to control a reversible electric motor 20 to adjust a flue damper 16 in accordance with fuel conditions in a boiler furnace. A diaphragm 28 is subject to pressure difference across the tubes in the boiler and displaces a balanced beam 34, one end of which co-operates with an orifice 74 of a fluid pressure relay comprising a diaphragm 52. Accordingly, clockwise movement increases fluid pressure in this relay and the diaphragm 52 carries upwardly a contact arm 122 which in succession closes contacts 132, 130, 128. When the last connection is completed, a relay 164 is energized and contacts 170, 172, 174 respectively close (1) a retaining circuit for the relay through contact 132, (2) a circuit through the reversible motor 20 and contact 130, and (3) a circuit through restoring magnet 186 which is maintained so long as the relay is energized. Similar effects occur on anticlockwise movement of the beam 34 from its mean position, but in association with contacts 138, 136, 134, relay 165, the other circuit through the reversible motor, and restoring magnet 187. The damper 16 is thus adjusted in accordance with fuel supply to maintain a constant pressure drop in the boiler furnace. The apparatus may be arranged to vary the speed of an electric motor driving a blower, by means of a reversible motor adjusting a rheostat, or selectively to energize high and low speed motors driving the blower. In these cases, correlated operation of a damper controlling the air from the blower may be secured by actuation thereof by a fluid pressure servomotor governed by the beam 34 as described in Specification 463,549. The arrangement may be such that the damper in each extreme position adjusts the motor rheostat one step in an appropriate direction, while the damper may be quickly displaced by the action of the magnet 186 or 187 to a new position to anticipate the result of the change in motor speed.

Title: Method of forming molecular diffusion bonded joints
Inventor: GREENSPAN HAROLD JACK
IPC: B23K20/00
Filed: 1970-10-16
Abstract: 1275377 Welding by pressure NORTH AMERICAN ROCKWELL CORP 16 Oct 1970 49346/70 Heading B3R [Also in Division C7] A method of forming a diffusion bonded joint between metallic elements comprises heating the elements to a temperature below their melting points, and applying a steady unidirectional compressive force thereto with the elements mounted within a rigid restraining mass which prevents deformation in a lateral direction and which expands upon cooling from the bonding temperature. Mating surfaces of the workpieces which are at an angle to the compressive force (i.e. other than normal) or parallel thereto may thus be bonded together. As shown, Fig. 3, two cylindrical workpieces 30, 32 to be bonded at contacting cylindrical surfaces 34, 36 and a flange member 48 to be bonded to the end of workpiece 32 to form a finished member 64, Fig. 4, are mounted within a rigid restraining body 42 and with rigid cylindrical bodies 38, 40 mounted within the workpieces 30, 32. The workpieces and restraining members are mounted in a container 52 which may be evacuated and then filled with inert gas through connection pipe 58. The assembly of vessel 52 together with the workpieces and restraining bodies is mounted within a ceramic body 43 within an outer wall 45 which together supplement the restraining action of member 42. Platens 60 with electrical heaters 47 apply the compressive force necessary to effect bonding. The vessel 52 with the assembled workpieces and restraining members may be heated prior to mounting within the ceramic body 43. Restraining members 38, 40, 44, 50 may be of stainless steel while the outer restraining member 42 may be of a precipitation hardenable advanced alloy (see Division C7) which expands upon cooling from the bonding tem perature as does also the ceramic body 43, to facilitate release of the workpiece. The workpieces may be of titanium and in one embodiment (Figs. 5-8, not shown) titanium shims are placed between the restraining members to prevent their being bonded to each other during the bonding operation. Reference is made to diffusion bonding of workpieces of aluminium, stainless steel, titanium, nickel, tantalum, molybdenum, zirconium and columbium.

Filed: 1972-10-30
Abstract: 1413335 Banknote validation NATIONAL REJECTORS Inc GmbH 30 Oct 1972 [29 Jan 1972] 49863/72 Heading G1A The authenticity of sheet material is tested by a device using a pulsating radiation source, a detector receiving radiation transmitted or reflected by the sheet which is mounted on a conveyer, a detector circuit tuned to the source pulsation frequency, and a sensing device responsive to amplitude modulation of the pulsations by line patterns on the sheet. The source comprises an IR radiation emitter in the form of a GaAs LED energized by an oscillator. The radiation passes through an aperture (3) or a lens and is transmitted through a banknote as it is passed between the source and a plurality of semiconductor detectors (4) the outputs of which are applied to a selective amplifier tuned to the same frequency as the oscillator. The amplitude of the resulting signal varies in accordance with the passage of features of the note through the radiation beam and produces a characteristic envelope which can be analyzed for specific frequency components by means of a pair of parallel selective channels incorporating band-pass filters and rectifiers which feed amplitude discriminators (10) to produce logic outputs to a verification circuit (11) which is arranged so that a pass signal is produced only if the correct frequency is produced at the correct time relative to a synchronizing signal produced by the mechanical system moving the note through the measuring station. A circuit may be included for checking the dimensions of the note. An optical filter may be placed between the note and the photo-detectors to reduce the amount of ambient light.
