Title: An improved soap
IPC: C11D13/02
Filed: 1930-06-27
Abstract: In the manufacture of soaps containing potato as the chief ingredient, a potato mash is used which is made by boiling the potatoes with dilute sulphuric acid, the boiled mass being passed through a press.  The resulting pulp is agitated with weak alkali and after standing the surplus liquid is decanted leaving a mash as residue.  The mash is boiled with caustic potash lye, evaporated water being replaced, and palm oil or similar fat suitable for soap manufacture, is added together with a further quantity of caustic lye containing a small amount of tetrethyl ammonium hydroxide.  After saponification is complete, casein dissolved in boiling water containing caustic ammonia is incorporated.  After standing the supernatant liquor is drawn off and the soap is passed into a cooling form.

Addition to 668,195. Drawings to Specification. Class 98 (ii). The process of the parent Specification is modified in that the sensitive layer coated on the cellulose ester support is a hydrophilic colloid containing silver halide and an aqueous colloidal dispersion of a water-insoluble, soft, acrylate resin and in that this sensitive layer is subjected to a tanning development, e.g. in a hydroquinone developer. The emulsion may be prepared by mixing aqueous solutions of silver nitrate and 5 per cent excess alkali metal halide with an aqueous gelatine solution. One litre of this solution is then mixed with 800 grms. of an aqueous dispersion of acrylate resin. The tanning developer may consist of 1 part of an aqueous solution made up of pyrogallol, p-methylaminophenol sulphate, and potassium bromide mixed with 1 to 2 parts of an aqueous solution containing sodium carbonate and sodium sulphite and water to 20 litres. Following development, the support is immersed in a 5 per cent acetic acid bath after which it is treated as described in the parent Specification. The tanning developing agent, such as pyrogallol, may be incorporated in the sensitive layer and the tanning development effected by treatment with an alkaline solution, such as sodium hydroxide or sodium carbonate solution. The support may be provided with an antihalation layer by dyeing the back of the support or the support itself. and may be affixed to non-extensible sheeting, such as sheet aluminium or aluminium foil.

Abstract: 1,147,435. Fluid-pressure servomotor systems. DOWTY FUEL SYSTEMS Ltd. April 27, 1967 [May 3, 1966], No.19568/66. Heading G3P. [Also in Division F1] A fuel supply system for a gas turbine comprises a supply conduit 6 receiving fuel from a pump 1 and a flow control device 2, a branch 19 connected through a flow sensing device 21 to a first burner port 3, another branch 26 connected through a distribution valve 27 to second and third burner ports 4, 5 which are opened one after the other by movement of the valve in one direction and closed one after the other by movement of the valve in opposite direction, and a fluid servodevice 37 to control the valve 27 in response to an input signal of at least one engine-operating condition and to a flow signal from the device 21, the servo-device 37 determining the maximum fuel flow to the first burner which is a function of one or more engine-operating conditions and controlling the valve 27 to regulate flow at least to the second burner when the total supply in the conduit 6 exceeds the maximum flow to the first burner. The device 21 consists of an orifice 48 and a conical plug 49 coupled by an arm 51 and a torsion rod 53 to a pivoted member 41 controlling the discharge from opposed nozzles 38, 39 fed through restrictors 46, 47 from the conduit 6. The member 41 is also coupled to opposed capsules 42, 43 to which signals, such as compressor delivery and jet pipe pressure are admitted. Compressor delivery pressure in the capsule 42 holds the member 41 against the nozzle 39 until reheat fuel flow begins when the pressure at the nozzle 39 exceeds that at nozzle 38 and acts through a pipe 32 to hold the valve 27 in the fully closed position. As the flow increases, the plug 49 lifts and applies a torsional load through the rod 53 to move the member 41 towards the nozzle 38 so that increased pressure in a pipe 28 begins to open the valve 27 and a part of the total fuel flow first passes to the port 4 and later to both of the ports 3 and 4. The latter may supply reheat or by-pass burners. A valve 7 maintains the pressure in a supply pipe 8 for the device 37 while a valve 23 prevents fuel escaping into the port 3 until there is pressure in the conduit 6.

Class 38 (iii) Relates to a traction or like system provided with main series motors supplied in common with a number of auxiliary motors some of which have shunt field windings.

When the traction and auxiliary motors are supplied from the line the two relay-windings assist one another, but, in the event of voltage-failure, the two windings oppose and the low-current relay is quickly tripped,
