Title: Improvements in or relating to control mechanism for apparatus having a plurality ofelectrical devices which are operated in sequence
IPC: D06F39/00
Filed: 1959-10-20
Abstract: 886,210. Washing-machines. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 20, 1959 [Oct. 27, 1958], No. 35453/59. Class 138 (2). In an automatic washing machine, a desired washing programme is selected by means of a rotatable drum 25 which indicates the order and duration of the operations of the programme. The drum 25 is rotated by means of a control knob 29 and is mounted on a shaft 26 carrying cams for operating the contacts of a selector switch 30. The stage reached in the washing programme is indicated by a pointer 40 moved along the scale by means of a belt 36 extending from a pulley 37 over an idler pulley 38 to a reel 35 driven by a timer 15. When the pointer reaches the end of the scale a stop member 53 on the reel engages a pin 55 and prevents further rotation of the reel. The timer 15 continues rotating, however, and, by disengaging a clutch, allows the belt 36 to rewind itself on to pulley 37, and return the pointer to its initial position. The clutch comprises cams 51, 52 (Fig. 4) on the reel 35 engaged by cams 48, 49 on a drive member 47 secured to the timer shaft 23. When the reel 35 is held by the pin 55, the cams 48, 49 move the reel axially against the action of a spring 56 and snap past the cams 51, 52. The cam pairs are arranged at different radial distances to prevent interference. Closing of a main switch can be effected by pulling the knob 24 outwardly. Washing programmes.-In the example, eight different programmes are provided in a rotary drum machine, viz.: (1) a pre-wash in warm water, followed by a hot wash, a spray rinse, two deep rinses and spin drying. The timer is advanced manually from the pre-wash to the hot wash. (2) As in (1) but no pre-wash and a shorter hot wash. (3) As in (2) but a still shorter wash in warm instead of hot water. (4) As in (1) but for tinting, a dye being used instead of detergent. (5) For blankets; the tub not being rotated for washing or rinsing, but rotated to dissolve the detergent before the blankets are introduced and also for spin drying. (6) A short warm wash and a cold rinse-for wash- and-wear garments. (7) As in (6) but no spin drying-for drip-dry fabrics. (8) As in (6) but cold instead of warm wash.

Title: Improvements in or relating to the manufacture of soap
Inventor: OWEN RONALD VINCENT
IPC: C11D13/30
Filed: 1954-12-08
Abstract: A process of neutralizing the free caustic alkali in spent lye from a soap-making process comprises mixing a stream of the spent lye with a stream of fatty oil and vigorously agitating the mixture until substantially all the free caustic <PICT:0794428/III/1> <PICT:0794428/III/2> alkali has reacted with the glycerides in the fatty oil.  The oil may contain free fatty acid in an amount insufficient to neutralize more than a minor proportion of the caustic alkali in the spent lye.  Desirably, a part of the soap formed in the process is recycled to promote the reaction between the caustic alkali and the glycerides.  The process is preferably carried out at 90-100 DEG  C. with at least a 10 per cent excess of fatty oil over the stoichiometrical amount required to neutralize the free caustic alkali.  The exhausted spent lye from the process may finally be treated with an acid oil to extract any soap dissolved in the lye. An arrangement in which the process may be continuously performed is shown in Figs. 1 and 4.  Crude lye enters vessel 1 through conduit 4, fatty oil enters through 3 and a portion of the grained soap formed in the process enters through 5.  The mixture of lye, oil, and soap passes over weir 2 and thence through conduit 6 to vessel 7a. Vessels 7a, 7b, 7c are fitted respectively with pairs of baffles 8a, 8b, 8c and with impellers 9a, 9b, 9c mounted on shafts 10a, 10b, 10c driven by motors 11a, 11b, 11c at speeds of about 1000 R.P.M.  After passage through each of these three vessels in turn, the mixture, which then contains very little unreacted free caustic alkali, is pumped by pump 19 through distributing manifold 21 to settling vessel 22. The rate at which the mixture passes to vessel 22 is controlled by butterfly valve 17 which is actuated by a float/lever-arm arrangement 15, 16a, 16b.  The mixture in vessel 22 separates into an upper layer of aqueous soap and a lower layer of exhausted spent lye. The float 23 and cone 29 rise or fall according to the level of the soap/lye interface, thus opening or closing the orifice in collar 28, through which exhausted spent lye runs off through line 30 to be treated with acid oil, so that any dissolved soap may be recovered. The soap from the upper layer spills through slot 32 into gutter 33 and thence through slot 34, Fig. 4, which is a view in cross-section along line IV-IV of Fig. 1.  By adjusting the position of plate 37 the relative proportions of soap being recycled to the lye neutralization process through conduit 5, and to the saponification stage of the soap making process, may be controlled.  Two other arrangements of apparatus, similar in principle, are also described.

Abstract: 987,621. Indicating which of plural signal channels carries the signal of greatest magnitude BROWN, BOVERIE & CO. Ltd. Sept. 13, 1963 [Sept. 17, 1962], No. 36144/63. Heading G1U. A device for selecting the smaller or the larger of two currents comprises respective main transformers through which the currents pass, and an auxiliary transformer carrying four windings, one end of each winding being connected to the corresponding main transformer and the other end through a rectifier to a star point and through a rectifier of opposite orientation to a second star point, a fifth winding on the auxiliary transformer providing the output. In the Figure currents J 1  and J 2  in conductors 1 and 2 produce corresponding currents in transformers 4 and 5 which are connected as shown to the four windings 8-11 of auxiliary transformer 7. Windings 8 and 10 are oppositely wound to windings 9 and 11 as indicated by the arrows. Assuming J 1  > J 2 , current J 1  follows the path winding 9, rectifier 16, rectifier 14, winding 8. Rectifier 20 is cut off by the voltage induced in winding 11 by the current in winding 8, so the path of current J 2  is winding 8, rectifier 14, rectifier 18 and winding 10. It is shown that if the windings 8-11 have equal numbers of turns the ampere turns produced by J 2  cancel whereas those produced by J 1  add, so the output in winding 12 is equal to J 1  if winding 12 has half the number of turns of the other windings. Winding 12 may be connected to a further auxiliary transformer 23 to compare J 1  with a third current J 3  and produce an output from winding 23 equal to the larger of the two. The smallest of the three currents can be selected by changing over windings 8 and 11 and windings 24 and 27.
