Title: Improvement in corrosion preventive compositions
IPC: C10L1/24
Filed: 1941-12-24
Abstract: 578,476. Mineral oils; coating compositions for protecting metals. STANDARD OIL DEVELOPMENT CO. Dec. 24. 1941, No. 16606. Convention date, June 29, 1940. [Classes 91 and 95] Metal corrosion is prevented by coating the surface of the metal with a composition comprising a protective base and an amine having the general formula HOR-#N, where R is an aliphatic hydrocarbon, R<1> is hydrogen or an aliphatic or cyclic hydrocarbon radical and R" is an aliphatic or cyclic hydrocarbon radical. Suitable amines are diethyl amino ethanol, dibutyl amino ethanol, phenyl ethanolamine and p-tertiary amyl phenyl monoethanolamine, while the protective base may comprise a mixture of all three of (i) mahogany soap (ii) saponifiable fatty materials such as wool fat, fatty oils, cottonseed pitch, linseed distillation residues, stearin pitch or distillation residues of oxidized hydrocarbons and (iii) heavy mineral or synthetic oil. The corrosion-preventive composition may contain naphtha or other light hydrocarbon, heavy mineral lubricating oils, alcohols, soaps of alkali, alkaline earth or heavy metals, waxes, petrolatums, linear polymer thickeners, pour inhibitors, dyes, antioxidants containing nitrogen (e.g., phenyl or naphthylamine) or phenolic or phenolic ether groups (e.g., the product obtained by reacting p-cresol with tertiary butylene in the presence of concentrated sulphuric acid) amine-aldehyde or ammonia-methylene chloride-alkylated phenol condensation products, metal 'or organic base soaps derived from fatty oils, resins and fatty oils. In an example, a rust-proofing composition comprises coastal oil, woolfat, sodium mahogany sulphonate and diethyl aminoethanol. U.S.A. Specifications 2,182,992 and 2,184,952 are referred to. The Specification as open to inspection under Sect. 91 describes anti-corrosion compositions in which the radicles R' and R" of the amine are not necessarily hydrocarbon. They may be heterocyclic and may contain substituents such as OH, NH, and Cl. Details are given of tests carried out in which the properties of the anticorrosion compositions of the invention containing mahogany soap, woolfat and amine are compared with those of similar compositions containing such amines as dicyclohexanolamine, di-isopropanolamine, triamylamine and diphenylamine, and also with those of compositions containing (a) mineral oil, oleic acid and a chromate. (b) naphtha solution of oxidized petroleum and a tertiary alkyl phenolamine, (c) lard oil, aluminium stearate and triethanolamine, (d) a gasoline solution of oxidized lard oil and an alkylated phenolamine and (e) an oil-soluble castor oil, lard oil and a tert'ary alkyl phenolamine. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to panning devices for loading dough pieces or the like into tins
Inventor: PALMER AUSTIN RICHARD
IPC: A21C9/08
Filed: 1956-05-30
Abstract: 864,186. Panning dough. BAKER PERKINS Ltd. Aug. 26, 1957 [May 30, 1956], No. 16703/56. Class 87(2). A dough piece panner comprises a continuously moving conveyer belt 3 carrying a succession of baking tins 6 which are positioned in turn by stops 85 at a loading station, flaps 7 above the loading station which pivot downwards from a dough piece receiving position and a peeling conveyer 9 which lays dough pieces 5 in succession on the flaps, operation of the stops 85, flaps 7 and conveyer 9 being in timed relation. A feed conveyer 1 transfers the dough pieces, which have been twisted in a mechanism 33, to the peeling conveyer 9. Preferably a moving apron 32 is adjustably positioned above the initial stretch 20 of the conveyer 1. The delivery end of the peeling conveyer 9 passes round a hose roller 40 which is connected by links 41 to swing arms 42, retraction of which peels the conveyer from beneath the dough piece 5 and deposits it on the flaps 7. During the retraction the motion of the conveyer 9 is interrupted by a lost motion device, Fig. 3, in the chain-drive to the driving sprocket 52 of the conveyer. The chain 53 passes round sprocket wheels 54, 55 which are carried on a member 58 which is journalled on the shaft 51 of the sprocket 52 and has a toothed quadrant 59 meshing with another toothed quadrant 60 which is rocked by a cam 67. When the member 58 is swung clockwise lost motion is applied to the chain 53 and the movement of the conveyer 9 temporarily ceases. The stops 85 are spring-biassed to the tin-retaining position, from which they are moved when extensions 86 therefrom are pivoted by levers 89 on a shaft 90 which is suitably oscillated through a link 94. The flaps 7, Fig. 4A, are moved down and apart, allowing a dough piece to drop into a tin beneath, when a link rod 79 moves a crank 78, on the shaft of which one flap is mounted, and meshing quadrants 76, 77 cause the flaps 7 to move in unison. The cams 97, 80, 64, 67 which actuate the link 94, link rod 79, swing arms 42 and quadrant 60 are all mounted on the same shaft 61, securing the required timed relation. The shaft 61 is suitably rotated when a dough piece 5 arrives at the loading station by the engagement of a clutch mechanism 70 initiated by photo-electric detecting means 11. At the end of a panning cycle the clutch 70 automatically disengages the drive until the next dough piece arrives at the loading station. Specification 864,185 is referred to.

Abstract: 696,070. Switches held set and freed mechanically; thermal switches. ELECTRIC & MUSICAL INDUSTRIES, Ltd., July 4, 1951 [July 5, 1950], No. 16721/50. Class 38(v) [Also in Group XI] Apparatus for electrically heating liquids may comprise a coffee percolator in which an auxiliary heating element 5 is energised continuously and a main element 4 is controllable manually by a rotatable cam 13 or automatically by a bimetallic strip 15 secured in heat conducting relationship to the base 2 of a body 1 forming a liquid container. Switching means for the element 4 comprises a slotted resilient member 19 having a rolled end portion 22 and a stiffening rib 23. A movable contact 28 on an arm 20 co-operates with a fixed contact 29, and the bimetallic strip 15 may engage one end of the arm. With the manual control turned to "percolate", Fig. 2 (not shown) contacts 28, 29 are closed and element 5 also is energised. In the "keep hot" position arm 21 of the strip 19 is flexed by the cam 13 and as a result of the stiffness of arm 20, contacts 28, 29 are separated. In the event of the liquid completely evaporating with the main element energised, the container 1 becomes overheated, the bimetallic strip deforms to move arm 20 and open contacts 28, 29, and damage to the percolator is prevented. No damage results from the auxiliary element 5 only being energised.

Abstract: 659,246. Cable-laying sheaves. CATERPILLAR TRACTOR CO. June 29, 1949, No. 17173. Convention date, March 24. [Class 78 (v)] A cable-laying apparatus includes a cablelaying sheave 24, Fig. 3, to guide the cable as it passes from a guide sheave 22 to a winding drum 18, the said laying sheave being rotatable on an axis spaced from the axes of the guide sheave and of the drum whereby the cable will lead on to and off of the cable-laying sheave in the same general direction; a pivotal support 26 for the said laying sheave offset from and transverse to its axis of rotation; and means supporting the drum and the guide sheave in such a position as to tension the cable to produce a component of force tending to swing the said laying sheave about its pivotal support in anticipation of the advancing spiral of the cable as the laying sheave lays the cable upon the drum. Fig. 1. Twin control cables 16 intended for controlling scraper 13 towed by tractor shown are passed around twin guide sheaves 20, fixed on 13, through vertical pivotal member 14 pivoted horizontally at 15, around twin guide sheaves 22 fixed on frame 23, around twin laying sheaves 24 and are wound therefrom on to drum 18 rotatably fixed on the tractor frame. Winding right to left (Figs 3 and 4). Laying sheave 24 is rotatably carried by bracket arm 25 pivoted at 26 to the tractor frame, and cable 16 is wound from guide sheave 22, around said laying sheave 24, and on to drum 18, and the position of sheave 24 is so chosen that the resultant tensional force upon it is downwards (in direction A) so that the sheave pivots to the left about 26 and lays one layer of cable to the left, the swing of the sheave preventing wear on the cable as it is thus wound. Winding left to right (Figs 9 and 10). The direction of the cable winding from sheave 26 on to the drum has now changed due to the first layer of cable on the latter and the resultant tensional force upon the sheave is now upwards (in direction A) so that the sheave pivots to the right about 26 and lays a layer of cable to the right.
