Methods of performing the reactions, which are exemplified by examples include (1) heating shellac with a polyhydric alcohol, heating the product with a fatty oil or resin acid and finally esterifying with the polycarboxylic acid; (2) heating shellac with a fatty oil or resin acid, heating the product with a polyhydric alcohol and finally esterifying with the polycarboxylic acid; (3) heating shellac with a polyhydric alcohol and a fatty oil or natural resin acid and esterifying the product with a polycarboxylic acid; (4) heating a fatty oil and a polyhydric alcohol, adding and heating a fatty oil or natural resin acid, adding and heating shellac and finally esterifying with a polycarboxylic acid; (5) heating shellac with the fatty oil or natural resin fatty acids, then heating with a fatty oil-polyhydric alcohol blend and finally esterifying with a polycarboxylic acid; (6) heating a fatty oil, polyhydric alcohol and a fatty oil or natural resin acid, adding and heating shellac and finally esterifying with a polycarboxylic acid.  Suitable raw materials include: polyhydric alcohols--glycerol, ethylene glycol, butylene glycol, diethylene glycol, pentaerythritol; polycarboxylic acids--phthalic anhydride, maleic anhydride, succinic acid, sebacic acid, adipic acid, citric acid, or the acids obtained by the diene synthesis such as by the interaction of maleic anhydride and compounds having a system of conjugated double bonds; fatty oil acids--linseed, chinawood, soya bean, cotton seed, sunflower, fish oil fatty acids, stearic acid, oleic acid; natural resin fatty acids--abietic acid, pine tar oil acids; fatty oils--soya bean oil. To reduce the acid number of the product a high-boiling monohydric alcohol such as the monobutyl ether of diethylene or ethylene glycol, the monoethyl ether of diethylene glycol, lauryl alcohol or stearyl alcohol or small amounts of basic oxides such as zinc, lead or manganese oxide may be added towards the finish of the reaction. Varnishes derived from the products may be used in insulation or for coating metal for use in the canning industry.  Specification 451,278 is referred to.  The Specification as open to inspection under Sect. 91 also describes a method of interacting a polyhydric alcohol and a fatty oil, followed by blending the product with shellac and then by esterification with a polycarboxylic acid.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,270,903. Releasable fastenings. REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT. 15 May, 1970 [19 May, 1969], No. 23676/70. Heading E2A. In a system for electromagnetically locking and unlocking all the doors of a vehicle, each door has a pivoting member 16, Fig. 4, which is connected by a link 15 to a control member 1, the latter comprising a coil 5, Fig. 2, which is mounted on a shaft 7 so as to be movable between discs 2, 3 having an axial magnetisation. All the coils 5 are connected in parallel to at least one reversing switch 33, Fig. 1, the latter being connected to a battery 14 and being actuated either by means of a key 18, Fig. 4, provided for locking at least one of the front doors of the vehicle or by a control member 46 (Fig. 4) located within the vehicle. According to the direction of the current each coil 5 is attracted or repelled by the disc 2, Figs. 1 and 2, and is repelled or attracted by the disc 3 so that the shaft 7 is moved to fasten or unfasten the doors. When the key 18 is rotated the member 16 is pivoted to its locking or unlocking position according to the direction of rotation of the key. A heel 30, Fig. 3, of the member 16 engages a projection 31 which is integral with a shaft 34 of the switch 33, and a lever 32 is tilted to a position 32c or 32d, Fig. 7, to close the electrical circuit. At the end of movement of the member 16, the projection 31 disengages from the heel 30, the shaft 34 is returned to its inoperative position by a spring 36, Fig. 5, and the coils 5 are de-energised. An inertia switch 48, Fig. 1, is provided and closes automatically when a relatively strong shock is applied to the vehicle so as to energise the coils 5 to produce an unlocking effect.

Filed: 1919-09-27
Abstract: 147,377. Saunders, A. Sept. 27, 1919. Spray carburettors.-Consists in a modification of the carburettor claimed in Specification 120,839, in which the fuel is controlled by a suction-actuated double-seated valve with a variably grooved stem. Fuel enters at A and passes a valve Z to a conduit H, which is controlled by the main fuel valve B, but has a by-passage C leading to a chamber L whence fuel for slow running may pass through the bore D of valve B to a pilot nozzle 4, Fig. 2. In its passage to nozzle 4 the fuel is controlled by a variably grooved adjustable screw R which may be replaced by a screw such as Z. A double-seated valve F, X actuated by suction on a disk G closes the slow-running fuel passage when suction ceases and prevents, by its upper face, escape of fuel around its spindle which slides through a plug 2. The pilot nozzle delivers fuel at the upper end of a tube 6 through which atmospheric air may be admitted past a variably grooved plug 9. The main fuel valve B is lifted bv a radial pin which engages a washer K, the pin being carried by a manually actuated rod in a manner similar to that described in connexion with the rod C and pin E of Specification 132,751. The spindle of the valve B is variably grooved, and when the valve is lifted spraying takes place at the point N and is facilitated by air jets through passages O. At large throttle openings another column of air W comes into action to facilitate the brealdng-up of the fuel.
