Title: Method of and apparatus for making plastic lined vacuum bottle fillers
Inventor: ROWND ROBERT MCKEE
IPC: B29C49/24
Filed: 1965-04-09
Abstract: 1,039,954. Coated articles. ALADDIN INDUSTRIES Inc. April 9, 1965, No. 15197/65. Heading B6G. Vacuum flasks or other bottles are lined with plastics material such as polythene or polypropylene by introducing a shaped liner 2 (of generally conical form with a turned-out peripheral lip) into the bottle or flask 1, evacuating the space within the liner and between the liner and the bottle interior 7, introducing gas under atmospheric or other pressure into the liner to expand it against the walls 7, and hardening the liner. An electric heater 21 softens the liner before blowing. The liner interior is initially evacuated to prevent premature expansion, and is later filled with cooling air. The liner and bottle are supported in a rotated head 16 having passages 42, 54 for removal and introduction of air. To facilitate the initial evacuation the lip of the liner may have ribs &c. which space it from the top edge of the bottle. Automatically timed means are provided to introduce and remove the heater 21 and to admit and remove air. The liner 2 may be used immediately after moulding by replacing the heater 21 by a moulding core carrying the liner and having internal heating and cooling, and pressure and suction, channels.

Title: Improvements in cellulose derivative plastic compositions
IPC: C08K5/098
Filed: 1934-05-22
Abstract: Cellulose esters or ethers are stabilized by incorporating 0,01--0,3 per cent of a metallic salt of a hexahydro-benzoic acid calculated on the weight of the cellulose derivative.  The addition protects compositions containing cellulose esters or ethers from the discolouring effect of heat treatment.  Magnesium, calcium, strontium, barium, sodium, or potassium salts may be used.  Salts of naphthenic acid, or ethyl, methyl, propyl, or phenyl hexahydrobenzoic acid may be used.  The cellulose derivative may be an acetate, formate, propionate, butyrate, or nitrate, or a methyl, ethyl, or benzyl ether.  Plasticizers such as triphenyl phosphate, triacetin, dibenzyl tartrate, diethyl tartrate, dibutyl tartrate, dimethyl or diethyl phthalate, and ethyl toluene sulphonamide may be present. Solvents such as acetone, methyl acetate, ethylene-formal, ethyl lactate, formal glycerol, and diacetone-alcohol may be used.  Plastic compositions may be worked into sheets, rods, tubes, or blocks. Liquid compositions may be used as coating compositions, or for obtaining filaments, sheets, films, and foils by extrusion or casting by dry or wet processes.  The compositions may be formed into plastic sheets which are interposed between sheets of glass and the assembly is then pressed together.

Title: Improvements in machines for coating seeds and grain with powder
IPC: A01C1/08
Filed: 1944-08-11
Abstract: 585,421. Treatment of grain. JULIANS, E. H. Aug. 11, 1944, No. 15400. [Class 58] In a machine for covering the surface of grain with sterilizing powder, grain falls from a hopper 6 on to the inclined surface of an endless belt a covered with sterilizing powder, from which it subsequently passes into a discharge container 13. The belt travels in an upward direction, and, at the lower end of its run, it passes through a container 3 where it picks up powder on its surface. Projections 10 in the outer case 9 of the machine cause the grain to follow a zig-zag path during its descent, at the end of which it passes over a grating 12 which may be made to oscillate. As the grain passes over the grating any excess powder falls back into the container 3 and the grain then passes on through a shoot 24 in the container 13 to an elevator 22 for raising the grain to sacks 16. A scraper 27 bears on the belt to prevent any grain from being carried over the upper roller 2.

Title: Improvements relating to the treatment of waste liquors and precipitates therefrom obtained in the manufacture of cuprammonium silk
IPC: C01G3/10
Filed: 1928-05-25
Abstract: 291,380. Bemberg Akt.-Ges., J. P. May 31, 1927, [Convention date]. Copper sulphate.-Waste liquors, and precipitates from such, obtained in the manufacture of cuprammonium silk, are treated with sulphuric acid to dissolve the copper present as copper sulphate, and also carbonize any organic matter which may be present. Sulphuric acid in excess of that required to convert the copper into sulphate is added, unless already present, and the mixture heated above 100‹ C., preferably between 130‹-140‹ C. The organic matter is decomposed, with the separation of carbon, and may then be removed and the resulting solution worked up to obtain the copper sulphate in a form sufficiently pure to be used again in the production of spinning solutions.

Title: A new or improved method of manufacturing hooks
IPC: B21K1/72
Filed: 1954-05-26
Abstract: 785,917. Making loops; bending; forging. CARTWRIGHT BROS.(ENGINEERS), Ltd., and CARTWRIGHT, A. B. May 16, 1955 [May 26, 1954], No. 15485/54. Classes 83 (2) and 83 (4). A method of making hooks, particularly for hoisting purposes, comprises bending a bar to hook shape in two stages in dies and subsequently forming the bent bar to the correct hook shape in finishing dies. A heated bar has its end pointed in die recesses 10, Fig. 1, in a pair of upper and lower dies A, B. The pointed end is then placed on a portion 112 in the die A and initially bent, Fig. 5. A roller rotatably mounted on a horizontal axis may be used instead of the flat portion 112. The bent end is then inverted, placed on a step 111 on die A against a stop 12, Fig. 7, and bent against a curved portion 11 to partial hook formation. The hook end of the bar is then transferred into a further die recess 13, Fig. 9, and is further bent to full hook form. The hook is then transferred into a die recess 14, Fig. 1, in the die A and drop forged to the correct hook form, Fig. 10 (not shown). The drop forging operation also serves to sever the hook from the remainder of the bar. The bending of the bar may be performed in a press or in a drop forging hammer. The final drop forging operation may be performed in separate dies from the preceding operations and may be performed in a separate drop forging hammer. Hooks with stub tips may be produced instead of with pointed tips.

Density separators.-An apparatus for separating liquids from gases and particularly for use as a, steam drier has a water separating chamber 3 disposed between an outer casing 1 and an inner casing 2. The outer casing has a number of tangential steam inlets 7 which direct the steam outside the annular baffle 6. The inner casing constitutes the steam outlet 4 and has an annular baffle 5. The water is separated out by centrifugal force and travels in a spiral path to the water outlet 8 which may be a pipe arranged tangentially at the maximum diameter of the separating chamber 3. The water discharge outlet 8 may be a slot between the outer casing 1 and a flange on the inner casing 2. In a modification, the area of the steam inlet is regulable. A deflector 10, Fig. 6, obstructs the direct flow between the inlet and the outlet and vanes 11 are disposed at an angle between the deflector and the casing. The gap through the vanes is varied by means of the annular member 12, and this mav be connected by a rod 16 to the valve 14 in the steam outlet. In another modification a flanged piston 13 is employed to vary the area of the inlet. Reference has been directed by the Comptroller to Specification 202,387.

Abstract: 319,808. Kolloidchemie Studienges., Carpzow, J. B., March M., Lenzmann, R., and Sanders, H. May 30, 1928. Body colours or pigments are made by bring- ing dyestuffs into intimate contact with salt- or fresh-water mud containing at least 20 per cent of unsaturated colloidal compounds, stated to be unsaturated silicon compounds, in the naturally moist or still reactive state, in the presence of metal salts which can form silicates with the unsaturated colloidal constituents of the mud, such as salts of aluminium, magnesium, calcium, barium, iron or copper, or by forming the dyestuffs from their components in the presence of such a mud. The colloidal constituents may be separated from the mud by washing or centrifuging, and may be allowed to stand for some time in a state of suspension, in the absence of air, with or without the addition of bacteria foods and anaerobic bacteria cultures, in order to in-- crease their activity. In examples, (1) fuchsine is treated with alum in the presence of mud of the character described, (2) crude aniline or a mixture of aniline and tolidine is mixed with the mud, dried, and oxidized by air or other oxidizing agents such as nitric acid or hydrogen peroxide; blue-red to white-red body colcurs are formed.
