Title: Water heating systems
IPC: F24D3/08
Filed: 1970-10-29
Abstract: 1278350 Water heating and storage PATTERSON-KELLY CO Inc 29 Oct 1970 [3 June 1970] 51416/70 Heading F4A  A water heating and storage unit includes a single tank 10 which has a water heating device comprising a shroud 18 closed at its outer end preferably by cover 30 wherein there is a water heater 22 in heat exchange relation with the water. A main conduit system 58-60-62-14 has a continuously operating pump 60 and a branch outlet conduit 66 leads from the tank as shown, preferably into a Venturi type fitting 68. A water temperature sensor 50 is connected to a heater energizing control 38 which in the preferred device supplies steam to heat exchange pipes 22. Connected to feed water supply 14 is a by-pass conduit 44 which discharges near sensor 50. For normal withdrawals from conduit 16, bypass 44 is inactive and water is replaced via inlet 14, but for large withdrawals, the baffles 24 prevent rapid replacement of water and so water is drawn into the tank 10 along by-pass conduit 44.

The emulsion obtained has a minimum of 30% by weight of "chain-form" silver halide crystals. In a suitable apparatus a mixer 12 is positioned in ripening tank 19 containing aqueous colloid solution 20, which is circulated by stirring blade 15. Reactant liquids supplied through inlets 17 and 18 are vigorously stirred at high-speed by blade 14 which may form a radial and horizontal stream. The seed crystals are discharged through strainer 16, become suspended in the colloid solution and are circulated through the mixer. In another embodiment the reactants are introduced at the bottom of the mixer and the seeds pass upwards into the ripening tank which may take the form of a cubic container.
Patent GB-517426-A (GB)
IPC: G03C7/14
Abstract: 517,426. Colour photography. COLOR RESEARCH CORPORATION. July 26, 1938, No. 22270. Convention date, Nov. 26, 1937. [Classes 98 (i) and 98 (ii)] A black and white colour-record line negative is produced by exposing a sen'sitive film 4, Fig. 1, to a coloured object through a three-colour band filter 1 having a recurring sequence of red, green and blue bands, an objective 2, and a diffraction grating 3 whose lines are parallel to the bands of the filter. Because of the recurrence of the filter bands, there is more than one position of the grating 3 with respect to the film 4 which will give sharply focused lines. After processing the film to a negative, it is reversed to a positive, or a positive is printed from it, and this positive (or the original negative) may be projected to produce a colour picture in the apparatus shown in Fig. 4, comprising light source 5, condenser 6, diffusing screen 20, three-colour band filter 1 similar to the taking filter, objective 7, diffraction grating 8 similar to the taking grating, the colourrecord positive 9, and objective 10 projecting the colour image on to a rotating ground-glass screen 11. This image may be photographed by a camera on to a sensitive film 14, such as a multilayer film, adapted to be processed to a colour negative which may be reversed to a colour positive or printed to yield a colour positive. Filters 1 with double or triple sequences of red, green, and blue bands are particularly described. Specification 516,986 is referred to.

Abstract: 1,125,439. Transformers. ENGLISH ELECTRIC CO. Ltd. 21 Dee., 1965 [23 Dec., 1964], No. 52291/64. Heading H1T. [Also in Division H2] A tap changing polyphase transformer system for supplying both a main and an auxiliary load is so arranged and interconnected that operation of the tap changing apparatus to vary the voltage applied to the main load does not cause changes in phase of the voltage applied to the auxiliary load. A three-phase transformer 4 comprises phase windings A, B, C, each of which is divided into three sections 1, 2, 3 of which the sections 3 are provided with tappings 10-16. Tap changing switches are associated with the tappings together with a reversing switch 5 so that the voltage selected by the tap changing switches can be arranged to buck or boost the voltages of the winding sections 1, 2 in series. The main load is supplied from terminals 6, 7, 8 or 1A1, 1BI, 1C1, this being determined by a step-down on step-up of the transformer, the transformer supplying the main load in autotransformer manner. Further windings A1, B1 C1 connected in delta are wound on the core links containing the winding sections 1, 2, 3, the delta point of the windings being connected to the secondary windings 17, 20, 23 respectively of transformers 18, 21, 24 to provide output terminals 18A, 21A, 24A supplying the auxiliary load. The primary windings 19, 22, 25 of these transformers are each connected between two phases of the transformer 4 at the " inner " ends of the winding sections two, the winding 19 between points 26, 28, winding 22 between points 26, 27 and winding 25 between points 27, 28. The phase positions of the transformers 18, 21, 24 thus correspond to those of the delta connected windings such that voltage regulation of the system by the tap changing apparatus has no effect on the relative phase positions.
