Title: Improvements in Carton Filling and Sealing Machines.
Inventor: HELSON GILBERT FORESTER
IPC: B65B7/20
Filed: 1918-07-13
Abstract: 122,788. Nelson, G. F. July 13, 1918. Machines for making boxes. A complete machine for filling and closing cartons, in which cartons with opened top and bottom flaps are placed in holders 22 on an endless chain 18, comprises the following arrangement for closing the bottom flaps before the cartons are filled. Upon leaving the station A, the cartons are carried over a plate 69 and a swinging arm 71, which turn up the right and left hand bottom flaps respectively. The arm 71 is connected by a link 81, Fig. 4, to a lever 80, connected by a link 82 to an arm 77 on a shaft 74, which carries a roller 84 in the path of the holders 22. The arm is raised by the passage of a holder and is returned by a spring 78. In passing over the plate 69, the front and rear bottom flaps are opened out at right-angles to the carton by the tapered end 69<a> of the plate and receive a coating of glue from a roller 86. As the front and rear flaps leave the roller, they are folded upwards by a pair of curved fingers 101, 102, Fig. 1. During the folding of the bottom flaps, the cartons are retained in the holders by a strip 105, Fig. 1, provided with a curved end 105<a>, which bends downwards the top side and rear flaps and causes the top rear flap to travel under the strip. On leaving the strip, the top flaps spring to the vertical position. The cartons are supported at the bottom and the bottom flaps are held in the folded position by strips 106, 108.

Title: Lubricating grease compositions
IPC: B23B47/20
Filed: 1959-04-06
Abstract: A lubricating grease composition comprises a lubricating oil gelled to a grease consistency with one or more soaps of hydroxy fatty acids and minor proportions of a water-soluble nitrite and an oil-soluble imidazoline.  The lubricating oil may comprise a mineral and/or a synthetic oil.  Examples of synthetic oils are synthetic hydrocarbon oils, silicate or phosphate esters, silicones (including chlorinated methyl phenyl silicone), polyoxyalkylene compounds and their ethers and esters, aliphatic diesters (e.g. dialkyl sebacates and adipates) and pentaerythritol esters.  The soaps may be alkali metal, alkaline earth metal, lead or aluminium soaps and may be formed in situ.  The nitrite may be an alkali metal nitrite, which may be supplemented by other water-soluble nitrites (e.g. organic nitrites such as substituted ammonium nitrites) or by water-soluble chromates (e.g. ammonium chromates or sodium or potassium dichromate).  Among the oil-soluble imidazolines which may be employed are alkyl- or alkenyl-imidazolines, N-alkylol-2-alkyl (or alkenyl) imidazolines and N-aminoalkyl-2-alkyl (or alkenyl) imidazolines.  The grease composition may contain additional ingredients such as oxidation inhibitors and metal deactivators.  In an example, a lubricating grease consists of mineral lubricating oil, lithium 12-hydroxy-stearate, sodium nitrite and N-hydroxyethyl-2-heptadecyl imidazoline.  For comparison purposes, a similar composition is described wherein the imidazoline is replaced by calcium petroleum sulphonate.  A grease consisting of mineral lubricating oil, lithium 12-hydroxy-stearate and N-hydroxyethyl-2-heptadecenyl imidazoline is also described.

Title: Improvements in and relating to systems for controlling temperature by electrical heating
Inventor: CORBETT JAMES PATRICK
IPC: G05D23/24
Filed: 1955-04-22
Abstract: 826,913. Automatic temperature control systems. ENGLISH ELECTRIC CO. Ltd. April 17, 1956 [April 22, 1955], No. 11676/55. Class 38 (4). In an automatic temperature control system the power supplied to an electric heater is controlled through an amplifier by a signal corresponding to the difference between a D.C. reference signal and a D.C. signal dependent on the temperature to be controlled, and is also controlled through a further amplifier by a rate signal, derived through a transformer from the first-mentioned signal. As shown, variations of the temperature of an electrically-heated oven 1 from a value determined by a reference signal applied at 2 are detected by a bridge or other balanced circuit 4 which compares signal 2 with the signal produced by a resistance thermometer or thermocouple 3. Any difference serves to restore oven temperature to the desired value by controlling, through magnetic amplifiers 5 and 6, the energization of a transductor 9 the A.C. winding of which is in series with the oven heaters. To reduce hunting, a transformer 7 develops a signal dependent on the rate of change of the error which also controls transductor 9 after amplification by a further magnetic amplifier 8. Magnetic amplifier 6 serves as an isolating amplifier and has a gain of unity or less. Signal 2 may be in accordance with a programme as in Specification 797,419.

Title: An improved process for making waterproof materials from paper, pasteboard, fabric and the like
IPC: D21H17/22
Filed: 1936-04-27
Abstract: Fat-tight and waterproof sheets are made by treating fibrous material such as paper, pasteboard, cardboard, and fabric with a solution of one or more alkaline-reacting substances, impregnating the treated sheet with a protein and chemically hardening the protein, e.g. with formaldehyde or chrome alum.  The alkaline reacting substances, for example, sodium or potassium hydroxide, ammonia, sodium, potassium or ammonium carbonate or tri-sodium phosphate are preferably used in warm dilute solution. The material may also be treated with surface-tension reducing agents, for example saponins, peptones, ammonia or alkali soaps and alcohols, either by a separate treatment or as an addition to the alkaline substances.  After the protein impregnation, the material may be treated with substances which reversibly precipitate or salt out the protein, e.g. concentrated solution of alkali metal, ammonium and alkaline earth metal salts or sodium salts of sulphuric, tartaric, citric or lactic acids. Proteins having opposite charges may be used for the impregnation, for example basic proteins such as gluten, zein and histones may be mixed with an acidic protein such as globulin.  The excess of acid or alkali necessary to keep such mixtures in solution is neutralized by alkali or acid in the hardening bath so that mutual precipitation, in addition to hardening, occurs.  The pretreated sheet may be impregnated with protein and hardening agents simultaneously, by using alkali or ammonium compounds of tanning substances which are decomposed by acid treatment.  The sheet material may be shaped to form containers such as bags and sausage skins by sewing or stitching.  Preferably shaping is done after the reversible precipitation and prior to hardening. Examples describe (1) pre-treatment of paper with an aqueous solution containing potassium stearate and carbonate, followed by impregnation with casein-sodium or sericin, then with a concentrated solution of ammonium sulphate and final hardening in a bath containing formaldehyde and ordinary or chrome alum; (2) pretreatment of paper with caustic soda or sodium carbonate followed by impregnation with hide glue mixed with casein-ammonia and excess ammonia, leading the material through a concentrated solution of sodium citrate or magnesium sulphate, sticking to form a tube with gelatine or casein-alkali, hardening with a mixture of formaldehyde and acetic acid, washing, and softening with glycerine; (3) treating paper first with tri-sodium phosphate solution, which may contain peptone, then with warm gluten or gelatine, hardening in aluminium acetate with formaldehyde if desired, washing, and softening with calcium chloride.  The sheet may be coated with a cellulose ester varnish.  Specification 241,876, [Class 140], is referred to  Reference has been directed by the Comptroller to Specification 241,876.

Abstract: 857,140. Aerials. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 9, 1959 [April 9, 1958], No. 12003/59. Class 40(7). A directional aerial comprises a primary unit consisting of a radiator or receiver of relatively small longitudinal extension and whose directivity is a function of the transverse dimension of its aperture together with a hollow arrangement of dielectric material having tapered or stepped transverse dimensions, the larger end of the arrangement being substantially in the plane of the aperture of the primary unit. The primary unit may be a suitably fed lens, paraboloid reflector or horn but in the embodiment of Fig. 1 is a horn 1 having a lens 2 arranged in the mouth of the horn, which is also the aperture of the unit. Beyond the lens are three coaxial tubes of dielectric material 3, 4, 5 getting smaller in diameter the further they are from the aperture of the unit. It is stated that energy is canalized by the dielectric arrangement so that it travels more, nearly parallel to the axis thereof and that it is distributed in a zone substantially as shown in the Figure. The overall length of the dielectric arrangement may be of the order of ten times the working wavelength and the complete system is then equivalent to a horn with an aperture two or three times larger than that of horn 1 placed at the outer end of the dielectric arrangement. Instead of the coaxial dielectric tubes a hollow dielectric cone placed with its apex outwards and its base in the plane of the primary unit aperture may be used (Fig. 2, not shown). Aerials according to the invention are very convenient for mounting side by side in the focal plane of a reflecting parabloid for producing overlapping beam patterns.
