Abstract: 582,607. Transformers. PHILIPS LAMPS, Ltd. July 17, 1944, No. 13653. Convention date, May 5, 1943. [Class 38 (ii)] A transformer having a variable output voltage is provided with an additional winding tightly coupled to one of the transformer windings and connected in parallel with the other winding in order to reduce the leakage reactance. The variable output voltage may be obtained by means of a sliding contact or tappings on the output winding. Figs. 1 and 2 show two arrangements of a transformer having a sliding contact on the secondary winding. In Fig. 1, the input terminals 15, 16 are connected to the primary and secondary windings 13, 14 which are joined in series, the output terminals 18, 19 being joined to a sliding contact 17 and to the point of interconnection between the windings 13, 14 respectively. The leakage reactance between windings 13, 14 is reduced by means of an additional winding 20 tightly coupled to the winding 13 and connected in parallel with the winding 14. The number of turns in the winding 20 is adjusted so that under no-load conditions the voltage induced in this winding is equal to the voltage across the winding 14. In the construction shown in Fig. 2, the additional winding 40 shunted across the secondary winding 33 is wound over the primary winding 31 which is not connected to the secondary winding.

Filed: 1939-05-09
Abstract: 528,541. Coin-freed article-delivery apparatus. SCHMITZ, H. May 9, 1939, No. 13831. [Class 27] Article storage compartments are arranged along either side of a conveyer band and each compartment has a power-driven deliverycarriage for removing the bottom article therein and placing it on the conveyer which carries it to the delivery position. The compartments contain articles at different prices and an article is obtained from any one by inserting the appropriate coin or coins. They may be disposed in the interior of a shop with the delivery point outside. The drawing shows one of the compartments 1 beside the conveyer 23. The delivery carriage has rollers 5 running on rails 4, and comprises a stirrup 9 connected by parallel links 7 with a base portion 4. In its initial left-hand position the links are collapsed and the stirrup lowered. Upon insertion of the appropriate coins a magnet 16 is energized and rocks a lever 15 anti-clockwise to raise the stirrup by engagement under a projecting tongue 14, a spring- actuated arm 18 locking the stirrup in the raised position. Simultaneously a switch 26 on lever 15 closes the circuit of a motor driving the conveyer 23 and a driving pinion 12 which is now engaged by a lower rack 10 on the stirrup. The. pinion 12 drives the carriage to the right along rails 4 and an upstanding arm 20 ejects the lowermost article in the compartment 1 on to a platform 21 on the stirrup. At the completion of the outward movement of the carriage the locking arm 18 is disengaged by contact with a fixed stop and the stirrup 9 falls to its lower position. Pinion 12 now engages an upper rack 11 on the stirrup and consequently returns the carriage to its initial position, the article being swept off platform 21 as it passes beneath the compartment and falling on the conveyer 23 to be conveyed to the delivery point. In its initial position, a projection 24 on the carriage restores the lever 15, but the circuit of the motor driving the conveyer and pinion is not interrupted until the article reaches the delivery position, the pinion running idly as the rank 11 has passed out of mesh therewith.

Abstract: 1,175,679. Delivering measured quantities of liquid; measures of capacity. RAVENHEAD GLASS Ltd. 31 March, 1967 [31 March, 1966], No. 14358/66. Heading B8N. An apparatus for graduating a measure of capacity such as a glass tumbler or other liquid container 39 having a mark to indicate its capacity, comprises a liquid measuring chamber 13 having an outlet valve 21, a support 28 for the container and probe means 27 adapted to contact the surface of the liquid in the container when the latter is raised by the support thereby stopping further upward movement and causing a marking device 40 to move towards the container so as to mark it. The measuring chamber 13 is mounted on a hollow rod 12 connected to a slidable sleeve 7; a resilient pad 128 is provided on the sleeve for contact with the lip of the container. The chamber is mounted within a liquid reservoir 1 and is provided with a guide tube 14 for the outlet valve 21. The support 28 is mounted on the end of the piston rod 37 of a hydropneumatic cylinder 38, Fig. 7a, and is provided with a resilient pad 29. The probe means 27 is in the form of a pair of wires connected to an electrical control means for the air supply to the cylinder (38). In operation, a container is placed on the support 29 with the apparatus in the position shown in Fig. 2. The support is then raised causing the lip of the container to abut the pad 128 thereby raising the rod 12 and the measuring chamber 13 so that the top of the chamber is above the level of liquid in the reservoir 1. The valve 21 is then actuated by means of cam contacting a roller 23 on the valve rod 20 thereby allowing a measured quantity of liquid in the chamber to drain into the container 39. The support is lowered thereby allowing the measuring chamber to again fill with liquid. The support is again raised and, at the same time, a switch in the probe circuit is closed so that when the end of the wires contact the surface of the water, the circuit is closed and thereby locks the hydropneumatic cylinder. At this stage the marking tool 40 which is in line with the contact end of the probe, is moved into engagement with the container so as to mark an enamel line on the latter; the container is rotated during the marking so that, if desired, a continuous line may be formed on the container. A number of identical dispensing and marking devices may be mounted on rotary machine, a single annular liquid reservoir (64, Figs. 7(a) and (b)) being provided.

Title: Polyurethane foam-producing composition
IPC: C08J9/00
Filed: 1965-04-07
Abstract: Polyurethane foam-producing compositions contain a non-reactive substantially homogeneous mixture of an organic polyol, an organic polyisocyanate or polyisothiocyanate and a foaming agent, one of which components, either alone or in mixture with another thereof, being in the form of minute encapsulated entities, releasable to bring about a reaction between the previously separated reactants. One of the reactants may act as the foaming agent. Examples of polyisocyanates are 2,4-tolylene diisocyanate, methylene bis-(4-phenyl isocyanate) and polymethylene polyphenyl isocyanate. Examples of polyols are adipic acid polyester polyol resin, polyisopropylene sorbitol polyether and trimethylolpropane. Foaming agents may be water, carboxylic acids, low boiling compounds which decompose with the evolution of gas when heated. A particularly preferred foaming agent is sodium borohydride.  The encapsulating material is an inert, film-forming, organic polymer, e.g. tristearin, ethyl cellulose, gelatin, gum arabic or polyethylene-maleic anhydride copolymer.  The encapsulation is accomplished by depositing this material from a liquid suspension, usually coloidal in nature, or a liquid solution on to the particles.  The component is released from the capsule by raising the temperature, thereby melting, softening or breaking the capsule wall or, preferably, imbibing the component into the wall. The usual catalysts are employed for the reaction particularly cobalt chloride.
