Title: Improvements in artificial breakwaters
Inventor: LAURIE ALEC HIBBURD
IPC: E02B3/06
Filed: 1955-11-02
Abstract: 805,789. Sea-calming. PNEUMATIC BREAKWATERS Ltd. Feb. 4, 1957 [Nov. 2, 1955], No. 31333/55. Class 113. A breakwater comprises a container having a siphon system adapted intermittently to discharge air or other gas supplied to it from a suitable source in the form of large bubbles which inhibit wave motion in the ambient sea water. Air is supplied from said source to a pipe on the sea bottom fitted with adjustable valves spaced apart and each discharging air to a container. In the Provisional Specification the container has a closed top and open bottom and is fitted with an air discharge pipe comprising a U-tube which operates like an inverted siphon. In the complete Specification the container 1, supported on legs 4, has an open bottom and a closed top 2 except for an aperture 3 protected by a grid 16 and from which depends a tube 10 surrounded by a tube 11 having a closed bottom 12 and spaced from the closed top 2. A buoyant flanged ring or valve 14 slides on the tube 11 as is protected by a grid 15. When air is supplied to the container the water level therein drops below the grid 15, the valve 14 drops, and the container continues to fill with air until the latter reaches the open bottom of the tube 10, starts to escape up the tube, entraining the water therein, and there ensues a sharp discharge of the air in the container until the siphoning action causes water to rise again therein and the valve 14 closes against the top 2. Air pressure then builds up to displace the water in the container and the cycle is repeated.

Title: Improvements in or relating to a process and apparatus for siliconising shaped elements consisting of silicon carbide
IPC: C04B35/573
Filed: 1952-12-11
Abstract: 727,612. Electric heating resistances and crucibles. SIEMENSPLANIAWERKE AKT.- GES. FUR KOHLEFABRIKATE. Dec. 11, 1952 [Dec. 21, 1951], No. 31448/52. Class 39 (3). In siliconizing shaped elements of silicon carbide particularly the ends of resistance heating bars 7, the part of the element to be siliconized is embedded in silicon powder and heated to the melting temperature of the silicon in a melting chamber maintained at a pressure above atmospheric pressure by sealing off the melting chamber from the air by a protective covering. Thus the ends of silicon carbide resistance rods 7 extend through apertures 5 in a carbon tube 2 heated by current therethrough, said ends dipping into ,silicon 6 in the tube. A protective layer 8 of quartz and coke powder placed above the tube 2 serves as a thermal insulator, protects the rods 7 against oxidation and allows gases occluded in the heated ends of the rods 7 to escape. The layer 8 seals the heating tube 2 from the outside and maintains the silicon vapour therein under pressure so that the end of the rod 7 is impregnated and alloyed with silicon. The ends of the carbon tube 2 are sealed by carbon plugs 3 to which are attached current supply conductors 4.
Patent GB-1080999-A (GB)
Title: Hinge fitting for a seat and back rest
IPC: B60N2/22
Filed: 1966-07-13
Abstract: 1,080,999. Hinges; adjustable car seats. RECARO A.G. July 13, 1966 [July 17, 1965], No. 31504/66. Heading E2F. A hinge for an adjustable seat back as described in Specification 1,002,810 has a latching mechanism which secures the rotatably mounted pivoted pin actuating the locking members in its releasing position when the seat back is pivoted forward, and releases said pin to lock the hinge when the seat back returns to its original position, together with means for adjusting the mechanism to operate at different positions of the seat back. The mechanism comprises a disc 16 rotatably mounted on the hinge pin 3 and in frictional engagement with the hinge member 2, e.g. by provision of friction material secured to either 2 or 16, the disc having its outer edge bent over into a cylindrical flange which is divided into two ring segments 16' by two arcuate slots 16", the pivoted pin 11 carries a projecting finger 14 which engages in one of the slots when the rod is in the position releasing the locking member 9 from 8, but is pivoted out of the slot when the rod is in the locking position. The frictional engagement between the disc 16 and hinge member 2 is sufficient that when the finger 14 is out of the slot 16" (i.e. when the handle 13 is moved to release the locking members), pivoting of the said member carries the disc around the axis of pin 3 and hence brings a ring segment 16' under the finger to secure the pin 10 in its releasing position. On restoring the hinge to its original position, the finger relapses into the slot due to the torque exerted by the spring 15, and the locking members re-engage. The disc carries a control arm 17 by which its position relative to member 2 can be altered against the frictional engagement with the latter. The length of the arcuate slots 16" permits the seat to be adjusted in a rearward direction simply by pivoting after disengaging the locking members, and the provision of two slots allows for use of the seat in either an upright or reclining position. In Figs. 4 and 5 (not shown) is illustrated an alternative embodiment of the hinge wherein the locking members are mounted on the pivot pin of the hinge, one member being slidably mounted on splines. The locking members are actuated by a tubular core, axially slidable within the hinge pivot pin, and this core carries a radially extending finger engaging in slots in a friction disc as before. The hinges are fitted with a return spring and two hinges may connected by the shaft mounting the locking members for the two sides of the seat, the second hinge locking the actuating rod, locking members and latching mechanism.

Title: Process for improving aqueous dispersions
Inventor: WHITBY FRANCIS JOHN
IPC: C08F2/22
Filed: 1960-09-13
Abstract: Aqueous dispersions are stabilized with an agent comprising a water-soluble salt of a synthetic copolymer of a half-ester of an unsaturated dicarboxylic acid with an ethylenic hydrocarbon which copolymer has an intrinsic viscosity in acetone between 0.01 and 0.1. The half-ester may be a C1- 12 alkyl or an aralkyl ester of maleic, fumaric, citraconic, mesaconic, itaconic or glutaconic acid; ortho hydrocarbon may be ethylene, propylene, butylene, styrene, alpha-methylstyrene or vinyl toluene; and the salt may be an alkali metal, ammonium or amine salt.  It is stated that polymers of the specified intrinsic viscosity result from slow mass polymerization at temperatures not above 120 DEG C. in the presence of a chain modifier which may be an amine, Schiff's base, nitro-compound, hydrazine, diazoamino-compound, haloalkane, thiuram or xanthic disulphide, or a mercaptan, thioglycollic acid or an ester thereof, or sulphur, selenium or phosphine.  In specific examples monobutyl maleate is copolymerized with styrene using benzoyl peroxide as catalyst, in Example 1 alone and in Example 2 with di-t-butyl peroxide, the modifier being beta-nitrostyrene in Example 1 and t-dodecylmercaptan in Example 2.  Both polymers are converted to the sodium salt.  The copolymer salts are used in amounts of 0.1 to 5% by weight of solids to stabilize dispersions of pigments in paints or polymer latices e.g. of natural rubber or of a polymer or copolymer of isoprene, butadiene, isobutylene, styrene and acrylonitrile.  The examples illustrate the stabilization of a styrene-butadiene copolymer latex. Specification 929,239 is referred to.

Title: Threads of foamed polyurethane and textile products comprising such threads
IPC: D01D5/00
Filed: 1955-11-04
Abstract: Threads which consist at least in part of foamed polyurethane having open pores are obtained by cutting a sheet of foamed polyurethane having the length and thickness of the thread required.  In one embodiment, the sheet is tightly formed into a roll which is secured and cut into slices, suitably with heated knives at 150-380 DEG  C., at right angles to the cylinder axis of the roll, the slices having the thickness of the thread required; the thread is then obtained by unrolling the slices. Alternatively the sheet may be shredded with heated wires, or cut under compression by means of cutter blocks (see Fig. 13) which comprise two calibrated co-acting grooved rollers 18. The threads obtained may be stretched up to five times their original length and may then be thermally aftertreated at 60-380 DEG  C. with infra-red radiation, by passing over hot calenders, or by passage through hot air.  Desirably <PICT:0825838/IV (a)/1> <PICT:0825838/IV (a)/2> <PICT:0825838/IV (a)/3> <PICT:0825838/IV (a)/4> <PICT:0825838/IV (a)/5> <PICT:0825838/IV (a)/6> <PICT:0825838/IV (a)/7> <PICT:0825838/IV (a)/8> (see Figs. 6-10), the threads 8 produced are reinforced with other natural or synthetic fibres 9, 10 and 11, such as wool, cotton, linen, jute, polyamides, polyesters, polyacrylonitrile and rayon.  If cutter blocks are used, these reinforcing fibres 21 may be embedded in the polyurethane threads 22 at the moment the sheet is cut (see Figs. 14a and 14b), suitably after the reinforcing fibres have been treated with a bonding agent.

Title: Improvements in or relating to electrical telecommunication circuits
Inventor: KNIGHT RONALD GEORGE
IPC: H04M7/10
Filed: 1965-07-26
Abstract: 1,049,359. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. July 26, 1965, No. 31807/65. Heading H4K. A sub-station is connected to the exchange by two 2-wire lines which are transformercoupled at each end and provide " go " and " return " channels, while a phantom circuit serves for the transmission of signalling conditions. The phantom loop may be completed at the sub-station through either of two paths separated by diodes D1, D2, one including a ringer RC. In the normal condition, negative potential is applied at the exchange to the " return " phantom through gate G1 When the sub-station is called, a bi-stable circuit I, R, changes over and positive potential is substituted through gate G2 to operate the ringer RC. Transistor T2 connected to the " go " phantom, responds to the loop closure and its output LSB goes negative. Upon the reply of the subscriber, contact S1 opens momentarily and contact S2 closes, so that the output of T2 goes positive to reset the bistable circuit I, R, thus tripping the ringing. When the sub-station calls, the closure of contact S2 operates transistor T1 and its output LSA controls T3 to give a calling signal. Dialled impulses are repeated forward by T1 T3. If the subscriber fails to clear at the end of a call, he may still be called from the exchange, but he must first clear and then reseize the line in order to trip the ringing.

Title: Improvements in and relating to the varnishing and printing of hollow bodies
IPC: B41F17/22
Filed: 1954-11-08
Abstract: <PICT:0782990/III/1> In a method of automatically varnishing and printing cylindrical or conical hollow bodies, prefabricated hollow bodies are conveyed by means of a flexible endless conveyer chain having uniformly spaced projecting rods for carrying the bodies from a varnishing to printing and other machines which are driven synchronously in a positive manner from the same source of energy. As shown in Fig. 1, cans 1 are fed by a conveyer belt 2 to a magazine 3 from which tongs 9 on a rotary plate 13 driven step-by-step grip a can while tongs 10 transfer a can to a mandrel 8 on a rotary plate of a varnishing machine 5.  After varnishing, tongs 11 grip a varnished can while tongs 12 transfer a can to a projecting rod on an endless conveyer chain 17 driven by a sprocket 12.  The cans are conveyed through a drying chamber 21 and are then transferred to the mandrels 22 on a rotary plate 29 of a printing-machine 23. After being printed they are restored to the chain or another chain and dried by passing through a drying chamber 32.  The cans are then discharged by means such as an air jet on to conveyer 35.  Finishing-machines such as for applying closures may be incorporated in the apparatus.  The tongs are operated by sliding cams and all parts are driven synchronously from a central shaft. A machine may be uncoupled from the shaft and driven by a motor such as 6 or 31.  Devices 42 are mounted to signal when there is no can on the chain to stop the machine.  A take-up device on the printingmachine allows for different spacing of the cans on the chain after leaving the machine.

Abstract: 661,288. Processing photographic films. PATERSON, D. M. Oct. 26, 1949 [Dec. 15, 1948], No. 32383/48. Class 98 (ii). A spool for receiving photographic film for treatment in a processing tank comprises a pair of spaced coaxial plates rotatable relatively to one another about. their common axis and each having on its inner face a spiral track defined by upstanding walls, each track having one end open for the insertion therein of the leading end of a film, one or each track being provided with at least one ratchet tooth, which has one face in a plane substantially radial to the axis of the plates and a second face inclined to the firstmentioned face, said inclined face being directed towards the entry end of the track in which the tooth occurs, and any succession of such ratchet teeth in a single track being spaced apart from one another. As shown, the spool is housed within a processing tank 1 having a light-tight cover 2 and comprises spaced plates 5, 6. A sleeve 7 projects from the inner face of plate 5 and provides an hexagonal recess 38 in which engages the end 37 of a winding knob 32. Projecting from the inner face of plate 6 is a sleeve 12, which is slotted longitudinally and has an internal rib 19 for engagement in a groove 17 on sleeve 7 whereby relative axial movement of the plates is obviated. Each plate 5 or 6 comprises spokes 10 integral with sleeve 7 or 12 and, as shown for plate 5, the inner face of each plate is formed with a spiral track 8, between adjacent convolutions of which slots 11 and grooves 9 are formed. Ratchet-teeth 20 project from the walls of the track, the inclined face of each track being disposed nearer the entry end 24 of the track. Humps 21 are also formed on the wall opposite each tooth and on the side thereof away from the entry end 24 to ensure a firm grip on the film during loading. In use, the plates are relatively rotated until the entry ends of the two tracks are opposite to each other. The leading end of the film is then inserted in the tracks until it has passed the first tooth and hump 20, 21 on each track. Thereafter, one plate is held stationary and the other is rotated so that the film moves further into the track of the stationary plate. When the plate has been rotated through 90 degrees the direction of rotation is reversed so that the film remains stationary. By keeping one plate stationary and oscillating the other plate, the film is wound on to the spool.
