Title: Improvements in or relating to labelling machines
Inventor: SHERRINGTON JOHN EUSTACE
IPC: B65C3/12
Filed: 1950-10-09
Abstract: 693,707. Labelling machines. RAWSONS (LABELLING MACHINES), Ltd. Oct. 3, 1951. [Oct. 9, 1950] No. 24612/50. Class 73. [Also in Group XVI] A labelling machine in which an article is rotated to apply the label has means to guide the label as it is fed to a gumming roller to ensure accurate positioning of the label on the article. Suction pads 54 on arms 53 extract a a label from the top of a magazine (not shown) and deposit it on a pair of conveyer belts 68. The belts 68 run over guide plates 81 and between adjustable lateral guides 86 which ensure alignment of the labels kept on the belts by rollers 82 carried by links 83 on a cross spindle 84. As the labels leave the belts 68 they pass onto a rotating grooved gum roller 90 from which they are guided by picker plates 104 into contact with an article which is placed between freely rotatable retaining rollers 6, 7 onto a rubber covered driving roller 14 by displacing the roller 6 upwards and rearwards against a spring mounting. The rotation of the article completes the label application as it rotates against the roller 6 which may be rubber covered. Themounting of the shafts 7 a, 8, 14a are all adjustable to allow for both different sized and tapered articles. Means are provided to raise the label pile automatically to keep it at a constant height and jets of air are played on the top edges of the pile to prevent more than one label at a time being withdrawn. A handleis provided to interrupt the vacuum supply and to stop the label feed when desired. The article supporting rollers and the label magazine and feed mechanism may be relatively adjustable laterally of the machine to apply the labels to different parts of the bottles.

Title: Process for the elimination of the unconverted polymer-forming monomers from synthetic linear high polymers
Inventor: LUDEWIG HERMANN FRITZ KARL
IPC: C08G63/78
Filed: 1953-09-08
Abstract: Monomer is removed from a fibre-forming condensation polymer by blowing superheated steam through the polymer melt in a turbulent manner.  The quantity of steam should be frm two to five times the quantity by weight of the melt.  In examples (1) caprolactam is polymerized in te presence of water and acetic acid by heating in an autoclave for an hour at 10 atmospheres pressure while allowing steam to escape.  After blowing off steam completely the melt stands for several hours at 260 DEG  C. and steam at 270-280 DEG  C. is blown through the melt for 3-4 hours using about 3 times as much steam as melt.  The melt is then spun after standing for 10-30 minutes for degassing.  The melt has a relative viscosity of 2.15 and contains 3.5 per cent water soluble compounds, 7 per cent monomer and dimer having been removed.  (2) Polycaprolactam chips are melted on the grid and steam at 260-280 DEG  C. is continuously blown in from below at 100 grams per minute, the polymer being supplied at 20 grams per minute.  The melt is then degassed and spun.  (3) An interpolymer from adipic acid and hexamethylene diamine (90-80 parts) and caprolactam (10-20 parts) is steam treated.  (4) Polycaprolactam containing 1/400 mol. of acetic acid per mol. lactam is blown at 270 DEG  C. with five times the quantity of steam to remove 6-7 per cent water-soluble compounds of a total of 10-11 per cent.  The polymer has a relative viscosity of 2.4.  (5) Similar to (4) the steam being condensed and the resulting solution when sufficiently concentrated evaporated to recover lactam.

Abstract: 675,455. Floor polishers. HOOVER; Ltd. Oct. 16, 1950 [Oct. 27, 1949; Oct. 27, 1949], No. 25154/50. Class 138 (i). Relates to floor polishers provided with means for facilitating assessment of the degree of polish obtained on the floor surface. A lamp is mounted on the polisher in such a position that light rays therefrom can be directed downwards and rearwardly to be reflected towards the operator's eye from the surface being polished. In the embodiment shown in Fig. 1 the polisher comprises a frame 10 and two motor driven brushes 11 (of which only one is shown), the motor and gearing (not shown) being enclosed in a hood 14. The hood has a front window 16 and a rear window 15 through which light rays from a front lamp 18 and a rear lamp 17 are projected forwardly and rearwardly of the polisher, respectively. The bail 19 of a handle 12 is pivoted to the casing at 13 below the level of the windows and in normal operation is inclined rearwardly at about 45 degrees to the vertical. The windows are arranged in relation to the lamps such that the front lamp illuminates the floor to a further distance in front of the polisher than the rear lamp illuminates the floor behind the polisher. Rays of light from the rear lamp 17 are reflected from the floor towards the operator's eye. In another embodiment one lamp is so arranged as to direct light both forwardly and rearwardly. The embodiment in Fig. 3 shows a lamp 33 mounted in a recess 34 in the bail 35 of the pivotal handle which lamp shines downwardly and rearwardly through a window 37. In this case the angle at which light rays are diverted downwardly and rearwardly on to the surface being polished may be varied, and a separate front lamp is provided. In another embodiment employing only one power driven brush the handle is rigid and inclinable with the frame and one lamp is arranged in the frame to direct light both rearwardly and forwardly. Specification 648,967 is referred to.

Title: Water-in-oil emulsions and their use as cylinder lubricants
IPC: F02B3/06
Filed: 1954-09-02
Abstract: A lubricating composition, which is suitable as the cylinder lubricant in internal combustion engines, especially diesel engines, which are run on a sulphur-containing fuel, consists of a water-in-oil emulsion wherein the oil is a lubricating oil and the aqueous phase contains at least 0.05 mol per litre of a salt of lithium or a divalent metal.  The lubricating oil may be a residual or distillate mineral oil, a synthetic hydrocarbon oil (e.g. of the polymerizate or alkylate type), or an ester oil. Blends of lubricating oils may be employed and these may include fatty oils. The lubricating oil may also contain such additives as pour point depressors, viscosity index improvers, extreme pressure agents, antioxidants, antifoaming agents, detergents and antiwear agents. The salt which is dissolved in the aqueous phase of the emulsion may be organic or inorganic and salts mentioned are formates, acetates, propionates, salicylates, phthalates, levulinates, glycocollates, succinates, nitrates, nitrites, chromates and sulphates.  Divalent metals mentioned are the alkaline earth metals, magnesium, zinc, cadmium and lead. Mixtures of salts may be employed and the emulsion may contain undissolved, dispersed or crystallized salt in addition to dissolved salt.  If desired, the water solubility of the salt may be increased by the addition of an auxiliary substance.  The emulsion may be prepared with the aid of one or more emulsifiers such as esters of polyhydric alcohols oil-soluble polyvalent metals salts of fatty, naphthenic or sulphonic acids, lecithin, oxidized vegetable oils, lanolin, resin acids, and polyhydric alcohol-fatty acidpolycarboxylic acid condensation products. Mixtures of emulsifiers may be employed such as a mixture of a polyvalent metal sulphonate with a polyvalent metal salt of an alkyl-substituted aromatic carboxylic or hydroxycarboxylic acid and/or a polyvalent metal phenolate of an alkyl-substituted phenol.  Numerous emulsifiers are specified.  In the examples, water-in-oil emulsions are described in which the oil is mineral lubricating oil and the aqueous phase contains magnesium sulphate, calcium nitrate or nitrite, or the acetate of lithium, calcium, barium, magnesium, zinc or lead.  For comparison purposes, similar emulsions are described in which the salt present in the aqueous phase is potassium carbonate, aluminium chloride, or the acetate of sodium or aluminium.  Emulsifiers used in the preparation of the emulsions of the examples are glycerol mono-oleate, basic calcium petroleum sulphonate, mixtures of basic calcium petroleum sulphonate and/or basic calcium salts of C14-C18 alkylated salicylic acids with calcium phenolates of C14-C18 alkylated phenols, and mixtures of basic calcium petroleum sulphonate with basic calcium salts of C14-C18 alkylated salicylic acids or with the calcium salt of a dioctyl phenolformaldehyde condensation product.
