Title: Chain welding machines incorporating apparatus for turning chain  links
IPC: B21L3/00
Filed: 1970-12-22
Abstract: 1333107 Welding by pressure P ESSER [trading as MEYER ROTH & PASTOR] 22 Dec 1970 [22 Dec 1969] 60992/70 Heading B3R  Apparatus for turning chain links about an axis perpendicular to the plane of the link if the link is wrongly positioned for welding comprises sensing means 20 ... 24 for detecting the presence of an incorrectly positioned link, a thruster member 32 adapted to be actuated by the sensing means to force the horizontal links on either side of the link to be turned into abutting relationship, a turning member 47 reciprocable at an inclination to the chain and arranged to force the forward curved end 57 of the link to be turned down through an angle of about 120 degrees, and a magnet 53 arranged to hold the curved end 57 in this position until normal feed of the chain is resumed thereby completing the turning movement of the link. The thruster member 32 is pivotally mounted on a lever 31 and is spring biased against the chain so as normally to tension the length of chain including the link being inspected by the sensing means. A cylinder 25 connected to the lever 31 controls the thrust movements of the member 32 the limits of its movement being determined by stops 45, 46. The sensing device comprises two fixed contact members 21, 22 arranged for sliding movement towards and away from the chain link by the action of a cylinder 24 and a spring loaded probe 23 mounted between the contact members 21, 22. The extent of movement of the probe 23 is controlled by the shape of the chain link thereby denoting the presence or absence of the weld gap. Electrical switch means are provided and controlled by the probe to control the actuation of the remaining parts of the link-turning apparatus. The whole apparatus is mounted on a slide 19 arranged adjacent the infeed track 10 of an electrical chain welding machine. A pivotally arranged sensing device (Figs. 7, 8, not shown) is arranged on the infeed track to detect abnormalities in the chain e.g. knotting of the chain or protuberances on the links thereof, the device having an aperture allowing the passage of normally arranged horizontal and vertical links but being pivoted out of position by an abnormal condition in the chain to operate a switch thereby stopping the chain feed.

Inventor: ONETO F E J
IPC: C11D1/00
Filed: 1968-12-23
Abstract: 1,247,189. Washing fibrous materials. UNILEVER Ltd. 23 Dec., 1968 [28 Dec., 1967], No. 61003/68. Heading D1P. [Also in Division C5] A liquid detergent composition having a pH of 4-7 suitable for the treatment of natural fibres contains 0.1-80% by weight of a detergent, a water miscible organic solvent, and an electrolyte, the relative proportions of the electrolyte and the organic solvent being such that the composition comprises two aqueous layers at 0‹C. The liquid composition may contain up to 90% by weight of the organic solvent, preferably 2-40% by weight. The amount of electrolyte is preferably 3-25% by weight of the composition and the amount of the detergent is preferably 5-30% by weight of the composition. The relative proportions of the constituents of the liquid composition are ideally chosen such that the weight of the lower aqueous layer is between 2 and 75% by weight of the composition. The electrolyte preferably forms part of a buffering system. The watermiscible organic solvent may be a straight or branched chain monohydric aliphatic alcohol (C 1-7 ), e.g. ethyl alcohol; a dihydric aliphatic alcohol (C 2-7 ), e.g. hexylene glycol; a monoalkyl ether of an aliphatic dihydric alcohol (C 3-6 ), e.g. the monomethyl ether of ethylene glycol; a dialkyl ketone (C 3-5 ), e.g. acetone; or benzyl alcohol or phenyl ethyl alcohol. Among the anionic constituents of the electrolytes may be used lactic acid, citric acid, tartaric acid, ascorbic acid, salicylic acid, phosphoric acid, ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriamine penta-acetic acid, 2- hydroxyethyliminodiacetic acid, sorbic acid, glycollic acid, and mixtures of these acids. The cationic constituents may be sodium, potassium, lithium, ammonium, and alkanolamines. Mixtures of salts may be used but it is preferable to use electrolytes other than those with solely mineral cations, e.g. sodium citrate, since these may lead to crystallisation. The detergent may be a conventional anionic, ampholytic, cationic or non-ionic detergent. The liquid composition may also comprise a layer of a liquid, water, immiscible, oily material, e.g. a silicone oil, vegetable, animal or mineral oil, the weight percentage of the oily material being up to 50% of the composition. In addition the composition may comprise foam improvers and stabilisers such as tertiary amine oxides, betaines and higher fatty acid alkanolamides; perfumes; colouring agents; preservatives; protein hydrolysates; antioxidants; germicides and pigments. When colouring agents are used, the liquid composition has two or more layers of different colour.
