Title: Improvements in or relating to the manufacture of soap
Inventor: HURT NORMAN ALBERT
IPC: C11B3/08
Filed: 1954-02-16
Abstract: Light-coloured soaps are made by treating an oil containing free fatty acids with a chlorite, then saponifying the chlorite-treated oil with alkali and bleaching the resulting soap with a hypochlorite; the salts used being preferably the sodium salts.  If desired, a soapstock may first be mixed with the oil in an amount insufficient to render the mixture neutral or alkaline, the soapstock having previously been bleached by treatment with a chlorite and hypochlorite, according to the method of Specification 762,687. Alternatively, sufficient soapstock to render the mixture neutral or alkaline may be added, the mixture being then treated with chlorite and hypochlorite so that the soapstock is bleached at the same time as the oil in the mixture is being subjected to the chlorite; the treated mixture may then be saponified with alkali and the resulting soap further bleached with hypochlorite.  The amount of chlorite used is betwen 0.1-10 per cent, preferably 0.5 per cent, of the oil; the hypochlorate solution (of 14 per cent available chlorine) is used in concentrations between 0.25-20 per cent, preferably 7.5 per cent. The chlorite treatment is suitably carried out at 40-100 DEG C., preferably 80 DEG C., for a period of 5-300 minutes, preferably 30 minutes.  If desired the chlorite and/or hypochlorite may be formed in situ by passing chlorine dioxide and/or chlorine gas into the alkaline solution at the appropriate stage in the process.  The preferred oils for this process are rapeseed, groundnut, palm, coconut, olive, and palm kernel oils and tallow. Examples and experimental results are given.

[Also in Group XL (c)] A burglar or other security alarm of the kind having an infra-red light beam projector unit, Fig. 1, and an infra-red light receiver unit, Fig. 2, the units being spaced apart so that the beam crosses the space to be protected, is characterized in that the units are battery operated, the projector unit has an interrupter disc 8 or drum rotated by a governed electric motor 6 so as to produce a pulsing beam of light, and the receiver unit is tuned to the frequency of interruption whereby interruption of the beam or variation of the frequency of pulsation (such as may occur due to projector being tampered with or becoming faulty) causes an alarm circuit to be energized. In the projector unit the light is produced by a normal flash-lamp bulb 2 which is located at the focal point of a plano-convex lens. An infra-red filter 4 is mounted so that it can be moved out of the light path when the alarm is being set up. The battery is held in a compartment 1A. The receiver unit uses a photo-transistor which is located at the focal point of a plano-convex lens 16. A reflector 18 is hinged so that it may be introduced into the light path to reflect the light to an etched glass viewing screen 19 provided with a graticule to facilitate the alignment of the receiver unit with the projector unit when setting up the alarm. The photo-transistor is connected to control an alarm relay through a transistor circuit (see Group XL (c)), the photo-transistor having an inductor connected in its base circuit of a value which is chosen to cause the circuit to resonate at the pulsing frequency of the light beam.

Abstract: 1,118,048. Electric correspondence control systems. RUCKER CO. Jan. 31, 1967, No.4755/67. Heading G1N. [Also in Divisions B8 and G3] Apparatus for loading and unloading cargo in a ship by means of a cable and a winch includes means for changing the length of the cable in correspondence with the vertical movements of the ship relative to the pier on which the winch is mounted. The cable 12 (Fig. 1) passes over a fixed sheave block 21 carrying one set of sheaves 22 fixed to the block and a second set of sheaves 24 movable vertically by a piston 25, controlled hydraulically by a valve 32. The latter is provided with an electrical actuator 41 energized by amplifier 44 and driver 47. The amplifier is fed with a first signal from a position transducer 42 e.g. a potentiometer, representing the height of movable sheaves 24 and therefore the length of cable 12, and a second signal representing the relative positions of the ship 7 and the pier 9, derived from a tachogenerator 51 coupled to an auxiliary line 54 attached to the ship 7, whose output signal represents the speed of movement of the ship and is integrated at 62 to obtain a displacement signal. The difference between the two inputs to amplifier 44 controls valve 32 and hence the vertical position of the movable sheaves 24, and therefore maintains the height of the cargo 19 above the ship 7 at a desired value irrespective of the vertical movements of the ship in the water.
