Abstract: 263,128. I. G. Farbenindustrie Akt.- Ges. Dec. 19, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Cellulose carboxylates; preparatory treatment of cellulose.-Cellulose, prior to esterification, is treated with formic acid in order to accelerate the esterification process and to effect an economy in anhydride. The formic acid is preferably used in concentrated form, and after the removal of the surplus acid, as by centrifuging, the treated product is washed and dried; hot formic acid of low concentration, for example, of 5 per cent strength, may be employed, in which case the washing step may be omitted. The treatment may be applied to cotton or to any other cellulosic substance free from lignine, and may be carried out at ordinary temperature or with heating.

Title: Perdisulphates from permonosulphates
Inventor: LEAVER JOHN PHILIP
IPC: C01B15/08
Filed: 1961-08-31
Abstract: Perdisulphates of lithium, sodium, potassium, rubidium, caesium, ammonium, beryllium, magnesium, calcium, strontium and barium are made by heating the corresponding permonosulphate at 75-300 DEG  C. and at a partial pressure of the hydrogen peroxide product less than 250 mm., preferably less than 100 mm. Hg. Preferably the permonosulphate is in association solely with aqueous hydrogen peroxide, e.g. as when prepared as described in Specification 992742 by the reaction of aqueous hydrogen peroxide and the corresponding bisulphate at 70-150 DEG  C.  The permonosulphate may be heated in a closed vessel, fluidized bed, spray drier or drum drier, optionally in the presence of bisulphate or strong oxyacid catalysts, yielding a perdisulphate of at least 96% purity.  Hydrogen peroxide, condensed or in aqueous solution, may be obtained as by-product.  In an example a solution of potassium permonosulphate, obtained by heating potassium bisulphate and excess hydrogen peroxide at 100 DEG  C. and 40 mm./Hg, was heated at 140 DEG  C. at 0.1 mm./Hg yielding a solid which on washing and drying analysed 98.2% K2S2O8.

The domain displacements may be sensed with magneto-resistive strips (23, 24) as described wtih reference to Fig. 8 (not shown). In the embodiment of Fig. 9, a bias field H maintains a domain 39 in a plate 33, a current in conductors 29, 30 produces domain deflection perpendicular to the direction of movement v of the record 34, thereby causing tracks 35 to be formed, and a fluctuating current applied to conductors 31, 32 produces corresponding fluctuations in the tracks 35 as shown in the ringed inset. In a similar embodiment (Fig. 10, not shown) conductors 31, 32 are omitted and the fluctuation (i.e. the signal) is applied to the bias field H to cause the track width to vary. The plate in which the domains are formed may also have a radiation-sensitive magnetic permeability, thereby allowing the domains to be moved by radiation means (not detailed).

Abstract: 1,262,028. Bread slicing machine. STINEMARK CORP. July 2, 1970, No.32108/70. Heading A4C. Slicing apparatus, for sugary bakery products, of the band-knife type comprises driven blades 32, conveyers 10, 12 for traversing the products relative to the blades and means for applying a film of water to the blades 32 to prevent a buildup of the product thereon. The bands of knives are mounted on a drum 28, driven by a motor operated by a spring-pressed solenoid switch 36, and an idler drum 30. The blades are led through guides 34 which rotate the blades through 90 degrees to align them with the path of travel of the products. The conveyers 10, 12 are driven by a motor 20 which is operated by a solenoid-operated clutch 22. The moisture applying means comprises a main conduit 40, closable at its lower end by a solenoid operated valve 52, and a secondary parallel conduit (41), Fig.3 (not shown) linked by cross conduits 42, 42 and 43, 43 which carry spray heads 44, 46 and 48, 50 respectively so that moisture is directed on to both sides of the blades 32 and also the drums 28, 30. In one system for supplying moisture to the conduit 40, air under pressure is passed along line 54, through an atomizer 58 which is supplied with water from a reservoir 60 to conduit 40. In the alternative, and preferred, system steam is supplied from a boiler to line 74 which has connected to it a by-pass 78 to feed condensed steam back to a condensate tank. The line 74 communicates with a conduit 72 through a solenoid-operated valve 82. Condensed steam may be passed from the valve 52 to the condensate tank. If further moisture is required it can be directed to the main conduit 40 via line 104. Two scraper-blade assemblies 84 are also provided. The motor 35 is started by closing switch 38, while closure of switch 24 engages the clutch 22, thus starting the conveyer drive, and also operates solenoid-operated switch 25 to start the moistureapplying means.

Title: Improved mechanism for the qualitative control of the fuel supply of internal combustion engines

Abstract: 456,943. Spray carburetters. GENERAL MOTORS CORPORATION, Grand Boulevard, Detroit, Michigan, U.S.A. Nov. 22, 1935, No. 32401. Convention date, Nov. 24, 1934. [Class 7 (iii)] A choke valve controlled according to intake pressure comprises an element which responds sluggishly to a decrease and rapidly to an increase in the pressure in the passage between the carburetter and the engine and a thermosensitive device operatively interposed between the element and the choke valve. An arm 46, Fig. 5, operatively connects an unbalanced choke valve to a shaft 45 urged in a clockwise direction to close the valve by a bi-metallic coil 52, the outer end of which is free to uncoil but engages, in coiling up as its temperature falls, an adjustable stop 51 in a plate secured to a hollow shaft 42 on the shaft 45. The shaft 42 is connected by an arm 43 and rod 44 to a bellows 20, the interior of which is subject to engine suction operating through a port 26 and passage 27 in the housing 18 of the bellows past a check valve 34. The valve 34 slides loosely over a stem 37 providing therebetween a restricted passage which delays the action of the engine suction on the bellows 20 and thereby causes the opening of the choke valve to be slow. As the bellows approach the collapsed position, if the choke valve is closed, a finger 57 on the arm 43 engages an arm 59 on a U-shaped member 53 secured to the shaft 45 to open it positively. Should a sudden opening of the throttle cause an increase in the pressure in the induction pipe, the valve 34 lifts and the bellows expand closing the choke valve rapidly.
