Title: Manufacture of polymeric materials from butadiene or its homologues
IPC: C08F36/04
Filed: 1943-02-15
Abstract: Rubber-like products are obtained by polymerizing an aqueous mixture comprising (a) one or more saponifiable derivatives of acrylic acid, methacrylic acid or a -chloracrylic acid; (b) butadiene-1 : 3 or its homologues or mixtures thereof; (c) persulphuric acid or a water-soluble persulphate; and (d) a water-soluble salt of an oxyacid of sulphur having reducing properties.  The saponifiable derivatives referred to are the esters, amides and nitriles of the said acids. In examples, butadiene is polymerized with acrylonitrile, methylmethacrylate and ethylacrylate in the presence of sodium hydrosulphite, sodium thiosulphate or sodium sulphite and ammonium persulphate. Phenyl-b -naphthylamine is used as an anti-oxidant and the sodium salts of sulphated sperm oil alcohols are used as emulsifying agent.  Disodium hydrogen phosphate and citric acid or sodium acetate and acetic acid are also added.  The polymers are coagulated with alcohol and brine and are washed and dried.  In another example, 2 : 3-dimethylbutadiene is polymerized with acrylonitrile.  Other salts of oxyacids of sulphur mentioned are alkali metal and ammonium pyrosulphites, bisulphites and sulphoxylates and addition compounds with aldehydes and ketones. 2-Methyl butadiene-1 : 3 is specified as a butadiene homologue. Soaps, sulphonated fats and oils and soluble cellulose ethers may be used as emulsifying agents.

Abstract: 866,666. Fasteners. BOOTS AIRCRAFT NUT CORPORATION. Jan. 22, 1960, No. 2465/60. Classes 89(1) and 89(2). An insert-fastener comprises a single flatplate 10 having teeth 11 and a screw-thread 19 to receive a screw 32, the side-pieces of the insert being joined by an archedportion 24. The thread 19 is parallel for part of its length and tapered on the portion adjacent the end 24. To secure a plate 33 to a phenolic or like base 15, the insert is entered into a slot 30, Fig. 5, in the base, and the screw is passed through a hole 31 in the base and screwed into the insert, which expands and is secured in the slot by the teeth 11. To obtain a better anchor for the insert, a longer screw is used to compress the end 24, thus moving the teeth 11 further into the base 15, and on further rotation of the screw, the thread on the insert is distorted to grip and lock the screw at 34, 35. In a modification, the insert has additional sinusoidal legs 38, 39, Figs. 8 and 9, bent to form downwardly-extending ends 38a, 39a, each of which has an upset 50 so that after the screw is screwed into the insert to expand the latter, the legs collapse and a plate 42 may be secured to the base 15 and the screw may then be removed. The base has an additional slot 45 for the legs, and the latter may have teeth 52 which grip the walls of the slot.

Patent GB-399370-A (GB)
Title: Process for the concentration of latex
IPC: C08C1/075
Filed: 1933-01-27
Abstract: Latex is concentrated by distributing it in finely-divided form in a layer of concentrated latex.  This extracts rubber particles and increases in bulk, while liquid, poor in rubber, passes through and forms a lower layer.  In a continuous process, a vat with a collecting channel around its upper rim, and a discharge opening near the bottom is filled with latex, on the surface of which is floated a layer of latex cream.  Latex to be concentrated, treated if desired with anti-coagulants such as soaps or carragheen moss, is sprayed on to the surface of the cream, preferably through a layer of air or other gas.  The cream layer increases in bulk and overflows into the collecting channel, while the liquor poor in rubber passes through, and is discharged from the lower part of the vat.  To ensure a gentle flow, the discharge may be led upward to just below the top of the vat, and baffles may be formed in the vat below the cream layer.

Abstract: 176,603. South, E. J. H. Jan. 27, 1921. Emptying; washing-out; filling.-Apparatus of the kind described in Specification 897/14 is provided with means whereby a locomotive may discharge its boiler products into the apparatus at the same time as another locomotive is being washed out or refilled. Each pipe line 7, 7<a>, 7<b> leading from different cleaning stations in the shed has two branches, one branch 9 opening into a collector 15 at the top of the separator 4, and the other branch 8 connected to the discharge passage of the supply pump 6. A gate valve 12 in each pump-discharge branch automatically closes a valve 11 in the corresponding collector branch when water is being pumped through the discharge branch. Similarly, a flap 10 in each collector branch automatically closes a valve 13 in the corresponding pump-discharge branch when boiler products are passing through the pipe line to the separator. The feed-valve 16 of the heater 5 is so operated by each of the flaps 10 as to open when boiler products are passing through a pipe-line. The operation of the feed-valve may be controlled by a thermostat in the separator or collector. The valves 13 may be dispensed with, and the flaps 10 so connected to the gate valves 12 in the respective pipe lines that the operation of a flap by the boiler products holds the corresponding gate valve in the closed position. Manually-operated valves 14 are fitted in each pump-discharge branch. As described in the above-mentioned Specification, excess water from the pump passes through a relief valve 20 back to the tank. The pump exhaust discharges through a separator 21 into the water in the separate tank compartments. The water may be heated by live steam, the admission to the compartments being controlled by thermostats.

Abstract: 1483134 Sorting seeds RANKS HOVIS McDOUGALL Ltd 20 Jan 1976 [28 Jan 1975] 3747/75 Heading B2H  A method of separating a mixture of seeds into wanted and unwanted seeds comprises feeding the mixture onto the surface 7 of an inclined upwardly moving belt where they come into contact with at least one fence 22 disposed at an angle to the direction of movement of the belt. In the embodiment shown in Fig. 2, there are a plurality of fences 22 each provided with an opening 23 and having its lower edge either just in contact with or spaced very slightly from the upper surface 7 of an endless belt. The surface 7 comprises tufts (27) of nylon bristles on a cotton woven backing. When a mixture of seeds is fed from a hopper (17) onto the surface 7 at a region 20, the mixture tumbles downwardly along first one fence 22 through opening 23 and then downwardly again to the next fence. The unwanted seeds, which may have a rough or hairy texture or have a different size or shape from the wanted seeds, get caught by the tufts and are carried upwardly by the moving belt, passing under any fence they may encounter before being discharged from the top end of the belt by a brush (12) Fig. 1 (not shown). The wanted seeds eventually reach the bottom end of the belt and are collected in a receptacle (26). In another embodiment, Figs. 5 and 6, the mixture is fed onto an edge region of the belt 29 through a plurality of inlets 36 and moves along the fences 39. The wanted seeds eventually reach the opposite edge of the belt and are discharged into a duct 34. The unwanted seeds are carried upwardly by the belt until they reach a rotating brush 40 which hurls them into an exit path constituted by a plurality of overlapping plates 43.

Title: Improvements in or relating to timber-stacking apparatus and the like
Inventor: AITKEN ROBERT LOUDON
IPC: B65G47/31
Filed: 1957-02-04
Abstract: 829,039. Stacking. TIMBER AUTOMATION Ltd. Jan. 31, 1958 [Feb. 4, 1957], No. 3760/57. Class 94(1).  Apparatus for stacking lengths of timber with horizontal spacing between them comprises a movable support for a layer of timber and stripping means for removing the layer, the stripping means moving more slowly than, but in the same direction as, the support so that the lengths are deposited onto the stack at spaced intervals. In one embodiment, the timber is advanced by a conveyer to collect against a stop 2. When the desired number of lengths has assembled, fingers 3 on a carriage 4 running along beams 5 pivoted at 6, are raised by anticlockwise pivoting of the beams, to lift the timber from the conveyer. Movement of the beams causes members 26 on a lever 27 to rise into the path of advancing timber on the conveyer. The members 26 are pivoted on an arm 29 on a support 33 secured to one of the beams. The fingers 3, having raised the layer of timber clear of the stop 2, the carriage advances to carry the layer to a position above the stack. The layer slides beneath a stripping member 35 on an arm 7, pivoted at 8 to a lever oscillated by a cam 38 through linkage 39-45. As the layer reaches its foremost position it contacts a switch 52 and a series of spacer sticks are released from magazines 51 to rest on the layer transversely of the lengths. The stack is supported on vertically movable beams 47 running on rails 49, the beams descending in steps corresponding to the depth of each layer and its spacers. The carriage withdraws and the layer abuts the stripper 35 which is, however, moved in the same direction by the cam and linkage. The timber lengths are thus discharged from the fingers 3 onto the beams 47 or stack at spaced intervals, the spacers finally resting across them. The last part of the forward movement of the carriage causes a roller 30 on the arm 27 to run up a cam plate 31<SP>1</SP> on the carriage so that the members 26 are withdrawn to permit a new layer to build up against the stop 2. The various movements are adjustable for different timber dimensions and spacings. In another embodiment (not shown) a layer is assembled on a table from which it is stripped onto the fingers of a carriage and from which it is discharged onto the stack as before.
