IPC: A23L29/256
Filed: 1965-12-03
Abstract: A product simulating an edible plant is prepared by contacting an aqueous solution of a water-soluble alginic acid salt, having a concentration of salt not exceeding 5% by weight, with a solution of edible alkaline earth metal ions to form an insoluble alginate film at the interface of the solutions which interface is maintained evenly and uniformly during the reaction period and diffusing the metal ions through the film at a constant rate to allow from 3.5 mg. to 11.5 mg. alkaline earth metal ions to be bound to 1 gram of alginic acid salt per hour.  The artificial plant product comprises an edible, crisp, chewable, non-uniform network of cells having walls of calcium alginate, a cell size of up to 3 mm. and aqueous cell contents. If the product is subjected to a freeze-thaw cycle at least 50% of the cells will have a size from 0.1-0.7mm. and the cell walls will be birefringent.  If not it will have a cell size from 0.1-0.2 mm. and the cell walls will be non-birefringent. The products with cell size 0.1-0.7 mm. mainly have fruit properties and those with cell size 0.1-0.2 mm. mainly have vegetable properties.  The interface of the solutions may be maintained by a dialysis membrane such as a sheet of "Cellophane" (Registered Trade Mark), nylon cloth or a fine mesh wire screen.  Additives which may be used in the alginate solution are up to 25% by weight of one or more sugars, starches, fats, gums or proteins.  Suitable alginic acid salts are the sodium, potassium and ammonium salts with apparent viscosity of from 100-900 cps. and in a concentration from 0.5-5.0%.  Suitable alkaline earth metal salts are calcium acetate and calcium lactate in a concentration from 1-12%, the lactate salt is preferred for making a fruit product.  In the preparation of a fruit product the slow freezing is carried out at -20 DEG  to +15 DEG F.  In the examples, products resembling a cucumber, melon rind, turnip, avocado, apple, pear, watermelon and honeydew melon are obtained.

[Also in Division C3]  Two surfaces, at least one of which consists of a plasticized polymer, are bonded by disposing between said surfaces an adhesive composition which consists of a mixture of a thermoplast and a latent solvent which is a solvent for the polymer, plasticizer and thermoplast at the "solution temperature " but is a non-solvent for the polymer and thermoplast at ambient temperatures, effecting pressure contact between the surfaces at above the " solution temperature " and then causing or allowing the adhesive composition to cool below the solution temperature. The " solution temperature " is defined as the minimum temperature at which the polymer and the thermoplast each form a fluid homogenous solution in the latent solvent. The plasticized polymer surface to be bonded is preferably a vinyl chloride polymer which may contain up to 15% of comonomers and this may be bonded to paper, cardboard, wool, wood, fabric or a surface of the same plasticized polymer. The thermoplast is suitably the same as the polymer of the surface or may be a chlorinated vinyl chloride or a chlorinated ethylene polymer and may contain plasticizers, anti-oxidants and UV stabilizers. The latent solvent may be a liquid at ambient temperature but is preferably a solid with a melting point of at least 50‹ C. Particularly suitable as a latent solvent is a lactam or mixture of lactams, especially #-caprolactam. The ratio of the thermoplast to the latent solvent is preferably between 10 to 90 and 90 to 10. The adhesive composition may be found in powder, particulate, chip or sheet form or in a solution in a common solvent such as methylethyl ketone or tetrahydrofuran, said common solvent being evaporated before contacting the surfaces. Shaped surfaces may be bonded by this method.

In a voltage regulator of the type in which voltage control is superseded by current control when the output current reaches a predetermined value, the load-current sensing and voltage sensing elements of the regulator are associated in a bridge circuit so arranged that the current which flows through the regulator on no-load, e.g. by way of the voltage sensing elements, has no effect on the load-current sensing elements. As shown, a regulator comprises a series transistor 11 controlled, by way of an adder 10, in dependence either upon output voltage variations as detected by a voltage divider 1, 2, 3 associated with a reference source U3 and a differential amplifier 9, or, when the output current reaches a predetermined value, in dependence upon output current variations as detected by a current sensing resistor 6 associated with a reference source U4, 7 and a differential amplifier 8. The resistor 6 and the resistor 3 of the voltage divider 1, 2, 3 constitute adjacent arms of a balanced bridge circuit 3, 4, 5, 6 and the current responsive differential amplifier is connected across the diagonal a, b of this bridge; as, in this arrangement, the no-load current I' of the regulator is applied to the other diagonal of the bridge, variations in the noload current do not affect the potential between a and b, so the differential amplifier 8 responds only to variations in the load current to control the regulator in its constant-current mode.

The illumination systems 7, 8 each comprise a lamp, reflector and lenses and are fixedly connected to carriers 3 and 4 respectively. A guide 14 is provided at the rear of illumination system 7 to guide the slides between the magazine 11 and the carrier 4. After slide change has been effected carrier 4 is moved forward into the focusing plane of lens 10, lamp 17 is gradually dimmed while lamp 16 increases in brightness so that on the screen one slide fades into the other. Carrier 3 is then moved rearwards and the slide change operation is repeated. The movement of the magazine is synchronized with the movement of the carriers. As a carrier moves rearwards the magazine is stepped back once so that the slide enters the slot from which it was taken. The magazine is then stepped forward twice and the new slide inserted. In an alternative embodiment a single illumination system is provided which moves transversely of the optical axes of the lenses 9 and 10 when both carriers are in the focusing plane so that one slide fades into the other.
