Patent GB-806457-A (GB)
Title: Shifting registers
IPC: G11C19/20
Filed: 1955-11-18
Abstract: 806,457. Pattern-movement stepping registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 18, 1955 [Nov. 19, 1954], No. 33070/55. Class 106 (1). A shifting register comprising a plurality of cascade connected electrical triggers is characterized in that in shift operations shifting pulses are only applied to those triggers that have to change their states. This is achieved by applying the shift pulses " sync," Figs. 3, 4, each of which appears in inverted form on lines 24 and 26, to the triggers (Fig. 1, not shown), via diode gates each of which is effective to pass either a positive or a negative shift pulse if the states of the two adjacent triggers are different. Consider for example the coupling between triggers T1 and T2 during the third time period shown in Fig. 4, which extends from sync pulse 2 to sync pulse 3. During this period trigger T1 is on, its output terminal 18 is at +25v, and trigger T2 is off, its terminal 18 being at - 25v and its inverse output being at +25v. Thus the potential of the common point of the two diodes 25, 27 is also +25v. However, on the occurrence of the third sync pulse this point is clamped to zero potential by the action of the diodes, and thus a negative pulse is transmitted to trigger T2 to put it on. Had trigger T2 been on initially then the potential of its inverse output would have been - 25v, the junction of the diodes would have been at zero volts, since resistors 19 and 21 are equal, and on the occurrence of the third shift pulse the junction of the diodes would remain at the same potential and no pulse is passed to trigger T2. In further embodiments, each trigger has a double diode gate, as in Fig. 3, attached to both sides (Fig. 8, not shown), and a number of such triggers are used in Fig. 9 as a reversible shifting register-the shift leads that are not being used being clamped to zero volts-and in Fig. 10, as a two dimensional matrix store with provision for shifting vertically and horizontally. A similar store, but of n-dimensions, is also described (Fig. 19, not shown). Further registers are also described with means for complementing, for parallel entry of data, and for reversing the order of the digits in the register (Figs. 17, 6 and 18 respectively, not shown). Each trigger could employ point contact transistors in place of triodes (Fig. 16, not shown).

Title: Vent Check Valve
IPC: F16K15/14
Filed: 1967-07-19
Abstract: 1,187,477. Valves. CRANE FRUEHAUF TRAILERS Ltd. 19 July, 1967 [19 Aug., 1966], No. 33079/67. Heading F2V. A combined vent and check valve assembly comprises a generally cup-shaped housing 12 which has an aperture 16 and is adapted to be attached, as by nut 24, to a container wall 22 having an aperture 20, the housing having disposed centrally within it a hub member 36, which hub member is secured to the housing by means of a bar 38. The hub member includes an annular recess 54 having two axially displaced seats 56 and 58 and the housing wall is rounded as at 26 to provide a further seating 28. A resilient rubber or plastics material member 32, having a central aperture 34, is disposed between the housing 12 and hub 36, the arrangement being such that in the event of equal pressures existing across the member, the latter attains the position shown in full lines in which it engages seats 28 and 58, whereas in the event of the pressure within the container slightly exceeding that outside it, member 32 attains the position shown in dotted lines referenced A. A sudden surge of pressure within the container forces the inner periphery of member 32 to engage seat 56, as shown in broken lines referenced C, whereas a vacuum within the chamber results in member 32 disengaging seat 28.
Patent GB-332983-A (GB)
Abstract: 332,983. Imperial Chemical Industries, Ltd., and Leicester, F. D. May 17, 1929. Acetic and formic acids; esters.-Acetic and formic acids are concentrated by adsorption of the vapour in active carbon, or, in the case of acetic acid the liquid acid may be treated. The adsorbed acid may be recovered by heating the carbon or by reduction of pressure or both, or by the action of volatile solvents; or the adsorbed acid may be used as such for the production of other bodies, for instance, for the production of esters by reaction with alcohols. In an example, acetic acid of 50 per cent strength is vaporized and the vapour is passed through a tube containing active carbon at. 130‹.: when the adsorption slackens, the admission of vapour is stopped, and the pressure is reduced by a vacuum pump, the acid being collected in fractions of 32 and 96 per cent strength. In another example, acetic acid of 33 per cent strength is passed through a vertical tube filled with active charcoal, the flow being stopped when the exit liquor contains 2 per cent of acid; the column is then allowed to drain, and is subsequently heated to 120‹ C. under vacuum, yielding a first fraction of condensate of 32.5 per cent strength, when the temperature is raised to 200‹ C. and a second fraction of 96 per cent strength is obtained.

Abstract: 1525371 Hand operated reciprocating pumps for dispensing liquids D F CORSETTE 9 Aug 1977 [31 Aug 1976] 33391/77 Heading F1A In a hand actuated dispensing pump comprising an accumulating chamber 14 and a pumping cylinder 30 in communication therewith, liquid is delivered to an outlet port 18 only when a downward stroke of a piston 34 creates efficient pressure in the chamber 14 to lift an outlet valve 28 against the action of a spring 32 to a position in which a cylindrical skirt 29 of the valve uncovers the port 18. The suction stroke of the piston 34 is performed by the spring 32, a co-axial inlet valve 26 being lifted away from its port 16 to allow liquid to flow to the chamber 14 from a dip tube 24. Each time the outlet valve 28 is opened a flange 46 thereon uncovers a vent passage 44 from the supply reservoir into which the dip tube 24 depends. Both valves, the inlet valve spring 48 and the cylinder 30 form a unitary assembly made from a plastics material.

Title: Improvements in or relating to the production of cellulose ethers
IPC: C08K5/13
Filed: 1943-11-22
Abstract: The stability of cellulose ethers is improved by incorporating therein up to 10 per cent of their weight of a polyhydroxy benzene. Specified polyhydroxy benzenes are hydroquinone, phloroglucinol and pyrogallol.  Ethyl cellulose and other alkyl celluloses containing up to 6 carbon atoms in the alkyl radicles which are soluble in hydrophobe organic solvents may be treated according to the invention.  The stabilising agent may be incorporated with the ether by forming a solution containing both constituents, or a solution of the stabiliser may be added to a solution of the ether. Alternatively, the ether in solid form may be treated in suspension with a solution of the stabiliser.  The stabilised ether may be precipitated from solution by adding a non-solvent thereto.  The solution of the stabilised ether may be used directly for the manufacture of filaments, foils, moulded articles and coating compositions.  To reduce the development of colour due to oxidation of the stabiliser, subsequent aqueous treatments of the stabilised ether are effected in a neutral or slightly acid medium.  Examples are given in which: (1) Ethyl cellulose and 1 per cent of its weight of hydroquinone are dissolved in a mixture of benzene and methylated spirits.  The ether and stabilising agent are precipitated by the addition of distilled water, the solvent removed by steam distillation, and the ether separated, washed and dried at 90 DEG -100 DEG  C.  (2) Ethyl cellulose is boiled in distilled water containing hydroquinone. The ether is filtered off, washed and dried at 95 DEG -100 DEG  C.  In the Provisional Specification catechol and resorcinol are also stated to be suitable stabilisers.
