Title: Improvements in multiple joints for metallic scaffoldings, framings and the like
IPC: E04G7/16
Filed: 1936-12-23
Abstract: 478,224. Scaffold clamps. TRIGGS, W. W. (Soc. Anon. Rolla, Traverso, & Storace) Dec. 23, 1936, No. 35319. [Class 20 (ii)] A multiple scaffold clamp comprises interconnected saddle members for receiving the scaffold members and a hinged clamping member for each saddle member so arranged that the axis of at least one of the scaffold members does not intersect the axes of the others. As shown in Fig. 1, the cradles 11<1>, 11<11> of two clamps are hinged directly to the extremities of the main cradle 11, the hinge-bolts 19 of the cradles, also serving as the hingebolts for the clamping bolts 151, 15<11> of the main clamping member 12. The scaffold members A, B, C are clamped in the main and auxiliary saddles by semi-cylindrical clamping members 12, 12<1>, 12<11>, and the scaffold members B and C are adjustable in a plane at rightangles to the axis of the scaffold member A and their axes do not intersect. In a modification, Fig. 3, the auxiliary saddle members 11<1>, 11<11> are pivoted directly to the main saddle member 11 by means of a common hinge-pin 22, the scaffold members B, C in this case being relatively angularly adjustable in the plane, or parallel to the plane, containing the axis of the main scaffold member A. In a further modification, Fig. 6, the auxiliary saddle members are disposed on the side of the main saddle member 11 remote from the axis of the main scaffold member A so that the axes of the scaffold members may be adjusted relatively in parallel planes ; in this example, the main clamping member 12 is provided with a hooked-shaped ear 212 and a slotted extension 212<1>, so that on release of the clamping bolts 26 the member may be moved axially in a direction parallel to the axis of the main scaffold member A to give a quick release.

Title: Manufacture of asbestos products by electrophoretic deposition
Inventor: HERON GORDON FREDERICK
IPC: C25D1/12
Filed: 1963-05-28
Abstract: Articles containing substantial proportions of both chrysotile asbestos fibres and organic polymeric material are produced by forming a mixed colloidal anionic aqueous dispersion of chrysotile asbestos fibres and particles of the polymeric material, applying a voltage between two electrodes immersed in the dispersion whereby the fibres and particles migrate towards the anode and form a deposit on it or on an ion-permeable membrane, e.g. a fine mesh cloth, in the path to the anode, and when a deposit of the required thickness has been formed removing the anode or membrane and the deposit as a unit from the dispersion. Typically the deposit is subsequently stripped from the anode or membrane either before or after drying.  The dispersion may also contain additional fibres not colloidally dispersed as well as other finely divided material, these additional materials being co-deposited with the asbestos and polymeric material, and may contain a water-soluble soap so that if the anode is of a metal that corrodes during the process a water-insoluble soap is also included in the deposit, thereby improving its wet-strength. To maintain the composition of the dispersion constant, the dispersion which preferably is continuously or periodically circulated in a separate circuit through a reservoir from which dispersion is fed by a metering pump to and through the electro-deposition bath is replenished periodically or continuously, e.g. with undispersed constituents which are dispersed by a pump in the reservoir circulation. The organic polymeric material may be synthetic rubbers, thermoplastic resins such as polythene, polyvinyl chloride, polystyrene or polyester resins, thermosetting resins or mixtures thereof. The additional fibres employed may be amosite or crocidolite asbestos or undispersed chrysotile asbestos, slag wool, or chopped glass fibre rovings while finely divided particles of metal, graphite, colloidal silica, clay, or lentonite may also be included in the dispersion, bentonite acting as a subsidiary dispersion agent. Examples of anionic dispersing agents are alkyl aryl sulphonates, alkyl sulphosuccinates or sulphated higher alcohols. The anode may be of Al, Zn, Cu, Pb, or Fe or of non-corrodible materials such as Pt or carbon, and may be a plate or cylinder.  Several anodes may be employed simultaneously and a diaphragm may be disposed close to the cathode to prevent cathodically evolved gas contaminating the dispersion.

Title: Improvements in or relating to pressure wave transmitters and receivers incorporating magneto-strictive devices
IPC: B06B1/02
Filed: 1932-12-15
Abstract: 411,903. Audible-signalling apparatus. MARCONI INTERNATIONAL MARINE COMMUNICATION CO., Ltd., Electra House, Victoria Embankment, and HINTON, N. P., 57, Broughton Avenue, Finchley, both in London. Dec. 15, 1932, No. 35620. [Class 118 (ii).] A magnetostrictive pressure wave transmitter and receiver is provided with a tapped winding so that a different and higher value of winding inductance is utilized for reception than for transmission. A discharge tube is connected across the grid and cathode of the receiving valve to prevent paralysis of the receiver during transmission. As shown in the Figure the winding of the magnetostrictive body MS is tapped at T3 and a polarizing battery B is connected through a high frequency choke HFC to this point. When the transmitting spark coil, (not shown) but connected to t1, t2 and shunted by main spark gap G is energized, the auxiliary spark gap SG breaks down and oscillating energy is applied between T3 and T2. The oscillating circuit is tuned by variometer V to the natural frequency of vibration of the magnetostrictive body. The voltage across T2, T3 is stepped up across the whole coil by auto-transformer action but the neon tube N breaks down to prevent excessive voltage passing to the receiving valve and paralyzing the receiver. During reception neither the spark gap SG nor the neon tube N breaks down so that the transmitting portion of the apparatus is isolated and the whole voltage generated in the winding W passes to the receiving valve. Specifications 402,123 and 411,879 are referred to.

Abstract: 1,182,363. Substation circuits. STANDARD TELEPHONES & CABLES Ltd. 26 July, 1968, No. 35856/68. Heading H4K. A subset for a looped PCM communication system comprises a stepping register 20 on to which all circulating codes are displayed while the subset is in the standby condition during which time the codes are inspected by an empty channel code detector 28 should the subset require a free channel for a call and are inspected by a subset number detector 22 should the code of the subset be circulated round the loop as a calling condition, detection of a code either by 22 or 28 operating a bistable 29 so that a store 30 records the position of the associated channel in a system cycle and so that a counter 25 synchronized by the bit stream on the loop operates a gate 21 repetitively for the duration of that channel so that the subset in that channel terminates the code arriving over the loop and substitutes a code read serially off the stepping register 20. The codes sent from 20 originate from a pushbutton set 26, on which calling codes are set up, or from a microphone encoder 37. Received codes when the subset is calling are the sent codes returned round the loop either unmodified (station busy) or modified (station being rung) and circuit 32 monitors these conditions with control over decoder 34 to connect appropriate ringing or busy tone to the earpiece 35. A clock 23 driven by the bit stream on the loop drives a synchronizing code detector 24 which with the appearance once each cycle of a synch. code zeros a channel counter 25.

Title: Process and Apparatus for the Heat Treatment of Synthetic Filaments and Threads
IPC: D02J13/00
Filed: 1967-08-08
Abstract: 1,178,470. Heat treatment of filaments. BARMAG BARMER MASCHINENFABRIK A.G. 8 Aug., 1967 [9 Aug., 1966], No. 36346/67. Heading B5B. In a process for the heat treatment of synthetic filaments and threads so that they may be stretched, set, and optionally shrunk in one working step, the filaments are passed over first and second heated rollers rotating at different peripheral speeds, the filament or thread is passed through a heating zone between the first and second heated rollers in such a way that in its passage between the two rollers the filament or thread is always at least at the temperature at which it left the first roller, but below the setting temperature of the filament or thread, the temperature of the second roller being sufficient to heat the filament to its setting temperature. Preferably the filament or thread passes through the heating zone without contact with any part of the apparatus, and the heat treatment on the two rollers and in the interposed heating zone is advantageously effected in the absence of air, an air-suction extractor being provided on the housing if desired. Either or each of the first and second heating rollers may be a stepped roller having steps which can be heated to different temperatures. Preferably the second heating roller is a stepped roller having a first step of larger diameter than the second step, so that a reduction in filament speed occurs as the filament passes from the first step to the second step, thus enabling the filament to shrink. The temperature of the two steps of the roller may also differ. Any convenient heating arrangement may be used in the heating zone, infra-red radiation, electrical induction or resistance heating being mentioned. Preferably the ends of the heating arrangement lie as close as possible to the heating rollers. In operation a filament 30 is drawn off by a creel 2, 4 from a supply position (not shown). The filament passes into the housing (not shown) through a slot (not shown) and travels with slight pre-tension over a heated roller 7 and associated guide roller 8. The filament is heated to its drafting temperature whilst on roller 7 and then passes without any contact over a heating arrangement 14 to a heated roller 9 which is maintained at the setting temperature for the filament. If shrinkage of the filament occurs during setting the filament, after travelling over the step 12 and guide roller 10 is guided on to a step 13 of the heated roller which runs at the same rotational speed as step 12 but is of smaller diameter thus enabling the filament to shrink. The filament loops several times around the step 13 of the heated roller and around guide roller 11 before emerging from the protecting and insulating housing (not shown) through a slot at the bottom (not shown).

Title: Improvements in or relating to centrifugal machines
IPC: B04B9/06
Filed: 1920-12-30
Abstract: 176,186. Broadbent & Sons, Ltd., T., and Broadbent, H. Dec. 30, 1920. Driving. - A centrifugal drying - machine is waterdriven and has maintaining and accelerating jets b, c; a hollow cylindrical valve e with a differential piston automatically cuts out the accelerating-jet after it has been working for a predetermined time, The piston f has two heads; one works in the chamber d<2> while the other, which is the larger of the two works in the chamber d<3>. The chamber d<2> has ports h leading to the accelerating-jet c and ports i leading to the maintaining-jet b. The chamber d<3> may be connected to the pres. sure pipe j through the relay valve k, and a port s in the wall of the chamber is opened by the action of the float in the tank v. When starting the machine, the operator moves the valve k to admit pressure to raise the pistons f, e to open the ports h, i to both jets c, b, and the cross-bar r then restores the valve k to its neutral position. When the jets have operated for a certain time, a definite quantity of water has collected in the tank v and the float then causes the port s to open. The piston f descends to the level of the port s and the piston e closes the ports h, thus cutting off communication to the accelerating-jet c. By manually moving the valve k to open the chamber d<3> to exhaust, the piston descends to cut off both jets b, c. If any part of the mech. anism fails, the piston drops to cut off the jets. A brake band z<2> is connected to a piston working in a cylinder y connected by a pipe x to the maintaining-jet, so that the brake band is held off while the maintaining-jet is in operation. A weight or spring may be added to the piston to apply the brake when the jet is cut off, and a dash-pot may delay the action.

Title: Center valve filter
IPC: B01D33/00
Filed: 1964-09-07
Abstract: An inward-flow vacuum filter drum (20), Fig. 1 (not shown) having solid end plates and trunnions has peripheral cells formed by radially- and axially-extending ribs (30), (32) which are interrupted at their centres so that a channel (31) is formed around the centre of the drum.  This channel is covered by an annular housing (50) of closed rectangular section, which is fixed to the framework of the apparatus and which constitutes the "valve" structure of the filter. Over an arcuate span of 180 DEG , filtrate flows axially along the cell bottoms (the imperforate inner cylinder (22) of the drum) to the housing (50) and out of a vacuum pipe (58) extending therefrom through the base of the filter tank.  A partition (64) across housing (50) separates this span from the next span, where wash liquid applied at (68) is withdrawn through a vacuum pipe (55) extending horizontally from housing (50).  A further partition (66) marks the beginning of the final, cake-removal, span where the vacuum is relieved.  In a modification, Figs. 6-8 (not shown), the housing (50) is replaced by a deckle strap, and the inner cylinder (22) has a central circumferential slot opposite the deckle strap so that filtrate flows directly into the drum interior; the washing phase is omitted.  In another embodiment, Figs. 9-13 (not shown), the filtrate flows directly into the drum interior and is discharged through an end pipe sealed through one of the trunnions; the valve element extends for only 120 DEG  over the cake-discharge and submergence portions of the filter cycle.  The circumferential gap in the drum is closed by a sealing band which rotates with the drum.  The valve element is held circumferentially fixed by a trough-shaped shoe which is itself prevented from moving by an axially-extending bar; the sealing band is guided over its trough portion.
