Title: Copolymerisation of semi- or non-drying alkyd resins with monomeric material
IPC: C08G63/48
Filed: 1964-03-10
Abstract: Semi-drying or non-drying fatty acid and/or oil modified alkyd resins are copolymerized with one or more vinyl or vinylidene monomers while adding a polybasic unsaturated acid in solution form to the copolymerization mixture. The polybasic unsaturated acid may be solubilized in the vinyl or vinylidene monomer or in a solvent or mixture of solvents.  Once the modified alkyd resin has been prepared, the monomer and the polybasic unsaturated acid may be jointly fed to the mixture or a portion of the acid (in solvent) may be added before the addition of the monomer commences.  In the examples:-(1) an alkyd made from tall oil fatty acid, pentaerythritol, ethylene glycol and phthalic anhydride in the presence of xylol is copolymerized with methylmethacrylate by adding a solution of the latter with maleic anhydride and tert.-butylperoxide; (2) an alkyd formed from soybean oil, pentaerythritol glycerin and phthalic anhydride is copolymerized with styrene and methylmethacrylate in the presence of maleic anhydride; (3) an alkyd formed from coconut oil, glycerin and phthalic anhydride is copolymerized with methyl methacrylate and styrene in the presence of maleic anhydride.

Abstract: Electrode layers are formed on a germanium wafer by jet etching coaxial flat bottomed pits in its opposite faces and then depositing nickel in one pit and indium in the other by simultaneous or sequential jet electroplating steps. The nickel plating solution consists of an aqueous solution of specified proportions of nickel sulphate, ammonium chloride and an aqueous solution of polyethoxylene ether and enough ammonium hydroxide to give a pH value of 8-9. The indium is plated as described in Specification 847,628.  A wire for attachment to the nickel layer is coated with an alloy consisting of 68 parts by weight tin, 31 parts cadmium and 1 part indium by passing a current between the wire and a carbon anode immersed in a solution, maintained at 135-145  DEG C., containing specified amounts of cadmium, tin, and indium chlorides, ethylenediamine tetra-acetic acid and glycerol. After attaching the wire the device is immersed in an etchant consisting of specified proportions of acetone and nitric and acetic acids and then electrolytically etched in a boiling solution of 4 molar potassium cyanide and 1 molar potassium hydroxide.

Abstract: 223,829. Brooking, J. H. C., and Fennell, C. W. May 1, 1924. Guarding against unauthorized use. - The change gear control mechanism is locked by means of a lug and a, lock both carried by a block or skeleton frame. In the construction shown in Figs. 1, 2 and 4, the operating lever 3 is held in, for instance, the reverse slot of the gate by a block 1 which is of such a shape that it can be inserted through the neutral gap by rotation about the point x so that the lug 4 engages under the bar 5. Removal of the block 1 is then prevented by a padlock 7, the body of which bears against the top of the gate and against the lug 6 on the block. In a modification the lock forms an integral part of the block. In a further modification shown in Fig. 9 a lever 16 is pivoted to the block and may be locked in the position shown in dotted lines so that the block cannot be withdrawn through the neutral slot in the gate. Fig. 7 shows a construction suitable for concealed gates. A skeleton frame 10 contacts with the floor and engages under the ball top 14 so as to hold the lever 11 in forward position. A padlock 15 prevents displacement of the skeleton frame.

Abstract: 944,997. Ratchet lifting jacks. BLACKSTONE & CO. Ltd. March 22, 1962 [March 23, 1961], No. 10721/61. Heading B8J. In a racket-lifting jack in which a pawl 21, pivoted to a lever 17, and a holding pawl 28, pivoted to the frame 11, 15, engage a rack 12, the pawls are interconnected to prevent them both from disengaging from the rack at the same time during the lifting operation. As shown, the pawl 21 is pivoted on a pin 20 on the lever 17 and is provided with a tail 24 which is connected by a spring 25 to a lug 26 on the lever 17. A link 33, pivoted at 34 to the frame 15, is provided with a slot 41 and a camshaped opening 35 engaging, respectively, a pin 42 on the pawl 21 and a pin 36 on an interlock lever 37 pivoted at 32 to the frame 15. The lever 37 has a cam face 38 which engages a roller 39 on the holding pawl 28. If pawl 21 is lifted out of engagement with the rack teeth 23, the pin 42 moves the lever 33 to the right and causes the lever 37 to be turned to bring its tail 43 into engagement with the pawl 28, thereby holding it positively in engagement with the rack teeth. To lower the rack, a rod 48, slidably mounted on the lever 17, is pressed inwardly to the position 48a thereby moving one arm of a spring 50 into engagement with a head 51 on the lever 37 and causing the cam face 38 to engage roller 39 to move the pawl 28 out of engagement with the rack. The other arm of the spring 50 engages a roller 56 on the tail of a driving pawl 57 and when the rod 48 is in the position 48a, the spring 50 overcomes the spring 58 and causes the pawl 57 to hook over the rack tooth 23, so that when the lever 15 is raised to lower the rack, the pawl 57 ensures that the rack is pushed downwards. Specification 721,616 is referred to.

Filed: 1944-06-07
Abstract: 578,211. Inflatable dinghies for aircraft. SARGEANT, R. S. June 7, 1944, No. 10936. [Class 4] Stowing and ejecting means for an inflatable dinghy comprises a cradle for supporting the inflating cylinder housed in the collapsed dinghy and which is subjected to an elevating force tending to urge the loaded cradle upwards to a dinghy-ejecting position, but is normally restrained by locking means which are released automatically by expansion of the dinghy during its inflation. In the form shown, the cradle 1 for supporting the inflating cylinder 13 and collapsed dinghy (not shown) is provided with tongues 16 normally engaging enlarged openings 17 at the lower end of vertical slots 18 in guides 6 at the sides of the dinghy housing, and is steadied by a block 19 between its upper surface and the housing cover 20. Inflation of the dinghy results in lateral displacement of the cradle causing the retaining tongues 16 to move into the slots 18 and the cradle to move upwardly under the action of tension members 22 connected to the cradle by cables 23 passing over pulleys 24, releasing the cover 20 against the resistance of self-releasing fasteners 21. When the cradle nears the end of its upward movement, the inner ends of levers 29 pivoted to the cradle at their mid-points 30 engage fixed abutments 32, causing rotation of the levers under the action of springs 31, and tilting a pivoted platform 27 to throw the dinghy clear of the mouth of the housing.

Title: An improved process for colouring hardened masses made from casein
IPC: C08L89/00
Filed: 1931-04-15
Abstract: Hardened masses of casein are coloured throughout by treatment with a solution of a compound which yields a coloured ion containing a heavy metal or which gives a colour reaction with casein.  Substances mentioned are nickel, cobalt, copper, chromium, and uranium compounds, solutions of cuprammonium oxide, cobaltammines, cobalt-mercury thiocyanate, alloxan, mercuric nitrate, alkaline copper sulphate (biuret reaction) and nitric acid, but not including dyes.  Small quantities of electrolytes (acids, bases, or salts) may be added to the solutions to assist penetration or may be incorporated in the casein before hardening. Marbled masses may be treated with the solutions to produce different effects; for instance, a marbled mass may be treated with a cuprammonium or a chromium salt solution to obtain other p  marbled effects.  The coloured masses are more resistant to water than before.  It is stated that hardened casein masses have hitherto been superficially coloured by means of an acid aniline dye, a design being then cut in to expose portions of the uncoloured interior.  The Specification as open to inspection under Sect. 91 (3) (a) includes the treatment of hardened protein masses of animal or vegetable origin such as yeast and the like, and is not limited by the exclusion of dyes.  The colouring may be effected by means of picrates, and a succession of reagents may be used to give a coloured effect; for instance, treatment with a metal salt solution may be followed by treatment with a liquid or gaseous reagent such as ammonium sulphide or sulphuretted hydrogen.  This subject-matter does not appear in the Specification as accepted.
