Abstract: 1,183,001. Correspondence control systems. HONEYWELL Inc. March 12, 1968 [March 29, 1967], No. 12024/68. Heading G1N. [Also in Division G3] Apparatus for producing an adjustable fluidpressure comprises a rotatable control shaft 24 connected to a calibrated pressure selection knob and to a differential pressure gauge 10 which produces an error signal representing the difference between the selected pressure and the actual pressure, which signal is fed to a coarse or a fire regulating device, according as the error signal is above or below a predetermined value, to bring the actual pressure into correspondence with the selected pressure. As shown in Fig. 1, the error signal is fed to an amplifier 12 and an electric switching arrangement 38. If the value of the error signal exceeds the predetermined level, set by a magnetic amplifier (76, Fig. 3, not shown), included in the switching arrangement the output signal from the amplifier 12 is fed to a first motor M1 mechanically connected to the coarse pressure regulating device 16 comprising two constant pressure sources 30, 32, one of which may be a vacuum source, connected via a needle valve controlled by the motor M1 to produce a required differential pressure which is bled off into line 34. A relay controlled valve 40 is opened after a predetermined time delay after motor M1 is energised to connect line 34 to lines 36 and 37. When the value of the error signal has been reduced to the predetermined value, valve 40 is closed and the error signal is removed from motor M1 and fed to a second motor M2 to adjust the volume of a bellows 44 of the fine pressure regulating device. Limit switches are provided for the bellows 44 whereby valves 49, 50 are opened and closed respectively if motor M2 drives the bellows to its limiting maximum or minimum volume. Limit switches are also provided for the coarse regulator 16 to cause the motor M1 to reverse its direction.

Title: Shift registers
IPC: G11C19/04
Filed: 1955-04-28
Abstract: 773,250. Electric digital - data - storage apparatus. BURROUGHS CORPORATION. April 28, 1955 [April 29, 1954], No. 12322/55. Class 106 (1). [Also in Group XXXIX] In a stepping register, the storage elements are arranged in blocks of at least three elements and advancing pulses are applied in sequence to the elements of each block. In this way, fewer elements are required for a given capacity, but the speed of operation is reduced. In one arrangement, pairs of bi-stable magnetic memory cores A, B are grouped with idler cores I to form blocks, each of three cores. Each core is coupled to the next by a transfer loop 21 and carries an interrogating winding 19. The interrogating windings are pulsed in sequence by a source 26 so that (a) the bit stored in the memory core B is transferred to the idler core I, then (b) the bit stored in the memory core A is advanced to the core B, and finally (c) a new bit is entered into the core A and the bit stored in the idler core I is transferred to the next memory core A. Thus the information is advanced by one step as a result of the three advancing pulses. More than two cores may be associated with each idler core. The input may be taken from a magnetic drum having a timing track to provide the advancing pulses. A modification employs thermionic trigger circuits as the storage elements with parallel readout.

Patent GB-377313-A (GB)
Title: Improvements in or relating to the manufacture of organic esters of cellulose
IPC: C08B3/22
Filed: 1931-04-28
Abstract: An organic ester of cellulose in solid form is treated with water under pressure at temperatures above 100 DEG  C., particularly 100-125 DEG  C., although excess pressures up to 200 lbs. per square inch may be employed.  Besides removing, or reducing the amount of, any combined sulphur, the treatment may modify the viscosity and solubility of the acetate &c., or may be controlled so as to leave these properties practically unchanged.  Its duration may be from a few minutes to 10 hours or more.  The quantity of water may be from about 4 to 50 times that of the ester.  If the ester contains much combined sulphur, the water may be changed intermittently or continuously, to prevent development of acidity and hydrolysis of the ester, or the acid may be neutralized.  The treatment may be carried out discontinuously in an autoclave or continuously in heated tubes or vessels, in which the pressure is maintained by a pressure release valve at the exit or by stand pipes.  A stable cellulose acetate with an acetyl content of 57 per cent (as acetic acid) may be obtained, which may be soluble in acetic acid, chloroform, chloroform-alcohol, acetone, acetone-alcohol, or acetone-water.  The esterification may be effected in the presence of solvents for the ester, which is then precipitated by water, benzene, toluene, isopropyl ether, carbon tetrachloride, or other diluent; or the cellulose may be esterified while suspended in a non-solvent for the ester, e.g. benzene, toluene, isopropyl ether, carbon tetrachloride, or petroleum ether. As catalyst there may be used sulphuric or chlorsulphonic acid, sulphuryl chloride, or a hydrohalide acid with or without zinc chloride or halides of iron, cobalt, nickel, or tin (Specifications 308,322, 308,323, 309,201, 312,095, 312,096, and 312,098, [all in Class 2 (ii), Cellulose &c.]). Before esterification the cellulosic material may be treated with lower aliphatic acids (Specification 263,938), [Class 2 (ii), Cellulose &c.], preferably in the case of wood pulp, after removal of the lignin, pentosan, &c. with caustic or other alkali.  The esters may or may not be ripened before the high-temperature treatment.  When ripening is carried out in suspension it is preferable to employ a medium such as ether in which water is soluble.  Examples are given in which the cellulose is acetylated in the presence of benzol until soluble in acetic acid, chloroform, acetone, or other desired solvent, washed and then heated with water under pressure.  According to the Specification as open to inspection under Sect. 91 (3) (a) other aqueous media may be substituted for water.  The presence of ,05 to ,15 per cent or more of sulphuric acid is not objectionable.  This subject-matter does not appear in the Specification as accepted.
