Title: Improvements relating to the polymerization of olefines
Inventor: NICHOLS GUS
IPC: C08F10/00
Filed: 1962-01-31
Abstract: C3 and C4 polyolefines are recovered free of aluminium chloride complex from a polymerization process in which one or more C3 and C4 olefines are polymerized with aluminium chloride catalyst whereby a polyolefine is formed in admixture with aluminium chloride-hydrocarbon complex, the mixture is settled to remove a major portion of the complex, the residual mixture is treated with anhydrous ammonia to form an aluminium chloride-ammonia complex which is then settled out. The olefines may be a butylene, e.g. isobutylene, or propylene and may contain a butane. The olefine may be contacted with the aluminium chloride at 0-80 DEG  F., the aluminium chloride-hydrocarbon complex may be separated in a first settling zone and the ammonia complex separated in a second settling zone, and the effluent from the second settling zone may be fractionated to remove unreacted hydrocarbons from the polyolefine.

Patent GB-311256-A (GB)
Title: Improvements in or relating to iron and steel alloys
IPC: C21C7/00
Filed: 1928-02-07
Abstract: 311,256. Haglund, T. R. Feb. 7, 1928. Alloys.-In the production of iron and steel alloyed with chromium or manganese by the reduction of iron oxide ores, rich, silicon-free chromium or manganese alloys, preferably ferroalloys, are added in such amounts that one part of the chromium or manganese is used as a reducing agent with the formation of a slag rich in chromium or manganese, while another part alloys with the reduced iron. A carbonaceous reducing agent may be used in addition, and metallic iron may be added. The raw material may contain chromium oxide which will form part of the slag, and the silicon content should be such that the slag will contain less than 20 per cent of silica. The slag should contain more than 30 per cent of chromium or manganese. Other alloy components, such as nickel, may be added, either in the metallic state, or as anoxide, or as a constituent of the chromium or manganese alloy. The whole of the charge may be mixed and briquetted. To reduce the amount of carbon in the final product, the slag is superheated before tapping, and magnesium oxide is added to raise the melting point of the slag.

Title: Improvements in or relating to hand-knitting devices
IPC: D04B39/00
Filed: 1940-03-04
Abstract: 545,494. Hand knitting-appliances. LUCHSINGER'S HANDELSGES (AMSTERDAM) FILIALE ZURICH. March 4, 1940, No. 4043. Convention date, Sept. 22, 1939. [Class 74 (ii)] A hand knitting-appliance has a set of fixed pins 19 and a set of slidable members 16 actuated by a cam plate 7 having an adjustable portion 74 so that the action upon the members 16 can be varied. In operation, a thread is wrapped around each of the fixed pins, and with the members 16 projected above the thread around the pins, a further length 25 of the thread is laid upon the members. The cam 7 is moved lengthways of the device to withdraw the - members 16 and to kink the thread 25 and the loops around the pins 19 are cast off as e.g. by a crochet needle. Upon subsequent movement of the cam 7 and projection of the members 16 more thread is laid and is kinked and the loops again cast off the pins 19. The adjustable portion 74 having a cam face 75 permits a more rapid retraction of the members 16, so that since fewer members 16 with their loops are retracted for the same movement of the cam the tension in the thread is reduced. By using additional spacing plates 71, the size of the knitted loops can be increased. With the form of device shown in Fig. 1, it is necessary to lift the block 21 carrying the pins 19 after each loop forming operation and to turn it through 180 degrees so that the fabric formed can be kept in its correct position. By providing a space 21<SP>11</SP>, Fig. 11, between the block 21 and the bed for the sliding members 16 through which space the fabric can pass the necessity for lifting and turning the block 21 is obviated.

Abstract: 1,043,112. Charge pumps; gas turbine plant. SCHWITZER CORPORATION. Jan. 31, 1964 [Feb. 13,1963], No. 4103/64. Headings F1B, F1G and F1T. An I.C. engine turbocharger comprises a valve which includes a member responsive to the gas pressure upstream of the turbine for opening the valve to permit gas to by-pass the turbine. The turbine is driven by the engine exhaust gases the pressure of which is attenuated, through the valve 44, Fig. 1, of a valve assembly 40, when reaching a predetermined value, thereby avoiding undesirably high intake manifold pressures at high engine speeds. The valve 44 is placed between a chamber 32 connected to the turbine inlet and a chamber 36 connected through a rectangular conduit to the turbine outlet 18. The valve seat 33 may be integral with partition 32a. In an alternative embodiment, Fig. 4, the valve assembly 40 is arranged on the engine exhaust manifold 20 and discharges gases therefrom, when the predetermined pressure is reached, through a conduit 61 to atmosphere independently or through an exhaust stack 18a connected to the turbine outlet.

Patent GB-582134-A (GB)
Title: Improvements relating to the production of polystyrene
IPC: C08F12/08
Filed: 1942-03-30
Abstract: In a process for polymerizing styrene in aqueous dispersion, a sulphite oxydizable by free oxygen is dissolved in the aqueous vehicle and air or an inert gas mixed with oxygen together with a catalyst for the sulphite oxidation is also present.  The sulphite is stable under the conditions of the polymerization in the sense that sulphur dioxide is not liberated from it. Sulphites specified are anhydrous sodium or potassium sulphites, ammonium sulphite, sodium bisulphite, sodium hyposulphite (Na2S2O4), potassium metabisulphite (K2S2O5) and acetone sodium bisulphite. Suitable oxidation catalysts are salts of copper, manganese, iron and cobalt, e.g. copper sulphate.  These may be present as impurities in commercial sulphites.  Emulsifying agents specified are sodium, potassium or ammonium stearates or oleate formed in situ and lauryl sulphonates. Protective colloids, e.g. gelatine, methyl cellulose, polyvinyl alcohol, saponin and gum arabic may be present.  Polymers of high molecular weight may be obtained by using only a small concentration of available oxygen in the reaction sphere.  Styrene containing diluents, e.g. ethyl benzene, plasticisers and fillers and obtained by pyrolysis of ethyl benzene or from coal tar, shale oil, petroleum distillates or drip oils from gas mains may be used.  "Aged" styrene is preliminary purified by distillation under reduced pressure or washing with sodium bichromate acidified with acetic acid or with ferrous p  sulphate in an atmosphere of nitrogen.  In an example, an aqueous emulsion containing styrene, stearic acid, commercial anhydrous sodium sulphite and ammonium hydroxide are heated at 90 DEG C., a slow stream of commercial nitrogen (containing 0.1 per cent of oxygen) being passed slowly through the vessel.  Polystyrene having an average molecular weight of 500,000 was obtained.
