Title: Process for the production of shockproof and cold resistant polypropylene
IPC: C08F10/06
Filed: 1963-04-17
Abstract: Propylene is polymerized using mixed Ziegler-Natta catalysts (defined) together with hydrogen which is present in the reactor only temporarily and in different quantities during the course of the polymerization, and another olefin is added in the absence of hydrogen towards the end of the polymerization, the other olefin being propylene and preferably ethylene and/or n-butene-1.  In the examples, propylene is polymerized in an autoclave containing titanium trichloride and aluminium diethyl chloride in benzene. Hydrogen is introduced (1) at the beginning of the polymerization and is subsequently vented and the polymerization completed in its absence, or (2) after an initial polymerization in its absence, or (3) in a limited amount such that the whole of the hydrogen is used up before the end of the polymerization, or (4) in the first stage only of a two-stage continuous polymerization process, the second stage completing the polymerization in its absence.  Ethylene and/or n-butene-1 up to a total of 10% based on the final weight of polypropylene produced may be added after the last of the hydrogen has been introduced.  The polymerization is terminated with iso-propanol.

Title: Method of and apparatus for feeding molten glass
IPC: C03B7/10
Filed: 1923-06-11
Abstract: 205,033. Hartford-Empire Co., (Assignees of Peiler, K. E.). March 22, 1923, [Convention date]. Delivering molten metal.-Relates to the method of feeding charges of molten glass through a submerged outlet, described in Specifications 194,675 and 195,376, which consists in alternately allowing the glass to issue from the outlet and then applying fluid pressure to retard the flow. According to the present invention, the fluid pressure is allowed to force the glass back against a resistance which is less than the resistance retarding the outflow of the glass. The device consists of a forehearth 11 having an opening 12 through which the metal is fed, the metal being divided into charges by shears 36. The feeding is further controlled by a cup 14 which is moved alternately to and from the outlet 12 and from which issues a stream of gas, preferably air at a fixed and controllable pressure, that tends to force back into the opening 12 the stub end of metal left after severing. The outflow of metal is regulated by a tube 13 which is arranged at an adjustable height above the opening. The stream of air from the cup 14 forces the pendant metal up into the tube 13, and the resistance to this movement is less than the resistance which acts on the metal flowing beneath the lower end of the tube. The bore of the tube may be of conical formation, or it may be restricted by a rod or tube the position of which is adjustable.

Abstract: 1173484 Cultivating micro-organisms on hydrocarbons VSESOJUZNY NAUCHNOISSLEDOVATELSKY INSTITUT BIOSINTEZA BELKOVYKH VESCHESTV 4 April 1967 15329/67 Index C5C 6C2 A micro-biological method of producing lipids comprises the steps of cultivating microorganisms capable of growing on a feedstock containing n-paraffin hydrocarbons on a nutrient medium containing such a feedstock, a nitrogen source, mineral compounds of phosphorus, potassium and magnesium, and trace elements, separating the micro-organisms from the nutrient medium and extracting lipids from them, and in the cultivation the nitrogen to n-paraffin hydrocarbon carbon ratio is 1:13 or lower i.e. giving more carbon relative to the nitrogen, whereby lipid production in the micro-organisms is promoted. Micro-organisms; Candida intermedia, Candida lipolytica, Candida quillermondii and Candida tropicalis, Nitrogen sources: ammonia water, sodium or potassium nitrate. The cultivation may be conducted in two stages, a first stage in which the micro-organisms are grown on a nutrient medium farowing their normal growth and protein is accumulated, and a second stage in which the nutrient medium utilized favours the production of lipids. The ratio of nitrogen to n-paraffin hydro-carbon carbon preferably is 1:13 in the first stage, but is no higher than 1:26 in the second stage. Spent nutrient medium separated from the microorganisms may be sterilized with ozone and then recycled. According to an embodiment, specified yeasts cultivated on C 11 -C 23  h-paraffins produced 18-32% of lipids based on the dry weight of the yeast. The crude lipid fraction obtained after extraction with solvent yielded 70% of polyglycerides with a molecular weight of 849 and 10% of mono- and diglycerides. The fatty acids were predominantly C 16 -C 18 . The lipid fraction also contained some hydrocarbon.

Title: A new or improved method and machine for filling, or partly filling, containers
Inventor: TROTTER ROBERT LAWSON
IPC: B65B43/60
Filed: 1948-06-11
Abstract: 650,503. Filling jars &c. LEVER BROS., & UNILEVER, Ltd. June 11, 1948, No. 15797. [Class 125(ii)] Jars, tins or the like are filled with liquid or paste by applying them to the underside of a rotary plate 2 in line with apertures 4 therein, whereby during the rotation of the plate 2 in contact with a stationary supply plate 15, the jars are exhausted, the vacuum is retained during the passage of the jar to the liquid or paste supply position, and the liquid or paste is admitted to the exhausted jar, the formation of bubbles being thus obviated. The first supply of liquid may be designed only partially to fill the jar, in which case a second exhausting of the jar prior to a second supply of liquid may be provided for. The jars 40 are fed by a belt or chain conveyer 30 to the filling machine, being released one at a time by a cam-operated finger 41 to be entrained by a rotating notched disc 31 which, in conjunction with a guide 33, presents the jars in succession to plungers 5 spaced circumferentially on a plate 3 which rotate in unison with the plate 2. The jars are accurately located on the plungers by pivoted V-guides 37, and, as the aperture 4 passes under a compressed air port in the plate 15, any paste lodging in the throughways of the plate 2 is blown into the jar. A cam-roller 12, belonging to end plunger 5, now raises a sleeve 7 which, through an interposed spring 9, raises the plunger 5 to press the jar resiliently against a pad 52. The aperture 4 then passes beneath an elongated suction port 21 in the plate 15, the exhausted jar being sealed by the plate 15 whilst the aperture 4 is passing from the suction port to the port 22 through which liquid is supplied to the jar under pressure. If a second vacuum stage is to be used, the auxiliary throughway 27 is brought into register with a vacuum port 26 in the plate 15 preparatory to registering the aperture 4 with a second liquid supply port 23. The jar then passes to a pressurerelief port 24 in the plate 15, so that when the cam-roller 12 falls, the jar may be separated from the pad 52 by a rotary notched disc 50 which co-acts with a guide 51 to position the jars on the conveyer 30 for transfer to the machine for applying paper caps as described in Specification 650,504. Paste removed by the suction system is collected in a trap between the filling machine and the suction pump. A small overlap between the application of the suction and the supply of the liquid is permissible, and, if paste is being packed, occluded air may be removed therefrom by feeding the paste as a ribbon through a vacuum chamber.

Filed: 1956-05-22
Abstract: 798,492. Incinerators. OAKLAND SCAVENGER CO. May 22, 1956, No. 15842/56. Class 51 (1). In an incinerator having a series of stepped travelling gates in a combustion chamber with a correspondingly stepped roof angularly disposed roof portions connect the horizontal parts of the roof with the substantially vertical riser portions, which terminate a substantial distance above the underlying grate to allow combustion products to flow from the lower grates to the upper grates. Refuse from a hopper 33 is delivered by a moving belt 34 down a shoot 36 to the uppermost grate 37 at the rear of the incinerator. The refuse passes down a series of grates 26 to the lowest grate 53, which discharges the residues on to a conveyer 66 constructed of interlocking pans so that moisture does not pass through it. Below each grate 26 is a horizontal row of pivoted overlapping louvres 56, each set of which can be opened by moving a bar 79, Fig. 2, connected by cranks 78 to the shafts 76 carrying the louvres 56. Vertical walls 54 below the grates and louvres 56 collect ash falling through the grates 26, and the ash is periodically dumped on to the conveyer 66 and quenched by sprays 71. Air inlet nozzles 52 at the side of each grate deliver air at different angles so that air is delivered over the entire width of the grate. The sloping parts 29 of the combustion chamber roof slope downwardly at about 45 degrees to break up the layers of hot gases and cause turbulence, and air inlet nozzles 61 in the roof of the chamber increase the turbulence. Gas or oil jets 61a in the front wall 22 of the chamber help to complete combustion, and a baffle wall 38 directs the products away from the shoot 36 to an outlet 62 in the side wall. Each grate 26 is driven by a separate motor, and the conveyer 66 discharges into a hopper 72. In a modification, Fig. 9, not shown, each grate is inclined downwardly at about 15 degrees to the horizontal. Specification 667,572 is referred to.
