Title: Improvements in or relating to apparatus for actuating controlling members dependent upon fluid pressure
IPC: G05D13/00
Filed: 1923-11-09
Abstract: 207,799. Graemiger, B. Nov. 28, 1922, [Convention date]. Fluid-actuated valves. - In apparatus for actuating a controlling member in accordance with the pressure of an actuating liquid or gaseous fluid, the pressure of this fluid is transmitted to a piston through the medium of a flowing auxiliary liquid. In the form shown in Fig. 1, the pressure of the actuating fluid acts on the auxiliary liquid in a vessel 1 communicating with a cylinder 8 containing a piston 9 connected to a controlling valve 11. The auxiliary liquid leaks past the piston to an outlet 12, and a float-operated valve 6 regulates the supply of auxiliary liquid to maintain a constant level in the vessel 1. In modifications of this form, the float-operated valve regulates the discharge of the auxiliary liquid from the vessel 1, and the cylinder 8 may be positioned in the vessel. In other forms, the actuating fluid enters a chamber 13, Figs. 4 and 5, separated by a diaphragm 15 from a chamber 14 to which the auxiliary liquid is supplied, a member 18 carried by the diaphragm regulating the supply or discharge of the auxiliary liquid.
Patent GB-787487-A (GB)
Title: Preparation of organic acid esters of cellulose
IPC: C08B3/06
Filed: 1955-10-05
Abstract: Cellulose esters of organic acids are made by separately activating cotton linters and wood pulp by pretreatment with a 1-4 carbon atom aliphatic acid free from acid esterification catalyst and a subsequent treatment with such an acid containing an acid esterification catalyst, blending the activated linters and wood pulp and esterifying the blend, e.g. with an organic acid anhydride such as acetic anhydride.  The 1-4 carbon atom aliphatic acid used in the pretreatment may be that of which the cellulose ester is to be made. The acid esterification catalyst may be sulphuric acid.  The blend of activated linters and wood pulp may contain 25-90 per cent of wood pulp, reckoned on the air-dry weights of the materials.  Before the esterification the pretreated cellulose may be cooled so as to freeze at least about 30 per cent of the lower aliphatic acid which it contains, to help in preventing an excessive increase of temperature during esterification.  The two-stage activation of the cellulose may be carried out by successively forcing the treating agents through the cellulose in sheet form.  Thus the lower aliphatic acid may be forced through a sheet of cellulose which has been saturated with water and which may or may not thereafter have been pressed to reduce its water content.  Part of the lower aliphatic acid in the sheet may then be pressed out and the mixture of lower aliphatic acid and catalyst forced through the sheet.  In an example, to 4 parts of cotton linters (dry basis) containing 6 per cent of water are added 1.4 parts of glacial acetic acid and the mixture is stirred for 15 minutes at 25 DEG  C.  A mixture containing 0.24 part of sulphuric acid and 2.8 parts of acetic acid is then added and the whole is stirred for 5 minutes more at 25 DEG  C. Simultaneously 4 parts of wood pulp (dry basis) containing 7 per cent of water are activated in the same way.  The cotton linters and wood pulp are then blended, and the blend is acetylated for 23 minutes with a mixture containing 24 parts of acetic anhydride, 296 parts of acetic acid and 0.60 part of sulphuric acid.  The two-stage pretreatment of the wood pulp and cotton linters separately enables esterification of the mixture to proceed more rapidly than when the wood pulp and cotton linters are mixed together before pretreatment.  Specifications 665,725, 683,648, 688,580, 706,522, 709,430 and 714,163 are referred to.

Title: Apparatus for the direct indication of the product of an instantaneous speed and another factor
IPC: G06G1/00
Filed: 1954-10-01
Abstract: 758,614. Speed product calculators. GENOUILLAC, J. DU V. DE. Oct. 1, 1954 [Oct. 2, 1953; March 12, 1954], No. 28391/54. Class 106 (3). In an apparatus for indicating the product of a speed v and a factor q which may be variable, a movable reference system is provided whose movement is an exponential function of 1 - with time and the speed vector is transferred q along a fixed axis of the reference system, the product qv being ascertained by the distance from the origin of the point where the speed of the movable reference marks is equal to v. As applied to fire control where the factor q is T the time of flight of the shell to the target an exponential spiral 1, Fig. 1, which is rotated 1 with an angular velocity of - so that the move- T ment of the points of intersection of the spiral with the axis RR<SP>1</SP> can be expressed as x = e<SP>-t/T</SP> or dx/dt = -x/T and an image M of the target is caused to move along the axis RR<SP>1</SP> with the velocity v so that where the spiral appears to move with the same velocity as the image x v = - or x = vT and the then distance x of M T from the origin is equal to the desired product, this being the point at which to fire the gun. In the embodiment in Fig. 3 the invention is utilized to ascertain the specific fuel consumption c of an engine where c = dE/dt. 1/Cα, E being the quantity of fuel, C the torque and a the engine revolution speed. The factor q in this embodiment is 1/Cα and is generated by a cylinder 5 rotated by a gear 6 from the engine 7 so that the cylinder rotates at a speed proportional to C.a. The cylinder 5 has an exponential helix 8 of the formula z = e# on its surface so that dz - = z.C.α. A second cylinder 9 has a simple dt helix 10 traced thereon for which z = # and this cylinder is rotated by a fuel meter 11 whereupon z = E and dE/dt = dz/dt. The two helices will have a common point along the axis RR<SP>1</SP> where they appear to have the same speed, at this point z.Cα dE/dt and hence the longitudinal co-ordinate at this point will be proportional to c the specific consumption. In Fig. 4 the instantaneous speed v is measured, the factor q being made equal to unity. A cylinder 12 bearing a simple helix 15 of formula z = # is rotated at a speed proportional to v so that dz/dt = d#/dt = v. A second transparent cylinder 16 outside the cylinder 12 is driven by clockwork 17 and bears an exponential helix 18 of dz formula z = e# whence 0 = t and - = z. At dt the point on the scale RR<SP>1</SP> where the speeds of the helices 15, 18 are equal, z = v.

Abstract: 206,862. Algemeene Norit Maatschappij, (Assignees of Sauer, J. N. A.). May 26, 1922, [Convention date]. Charcoal.-A process for producing uniformly active charcoal of the type in which a carbonaceous material is distilled in presence of active gases is characterized in that the raw material, which may be coal, brown coal, or coke produced by the low temperature carbonization of dense peat &c., is first pulverized or granulated preferably uniformly and then subjected to the action of heat and activating gases while being maintained in a state of agitation and suspension by a blast of gas. The raw material may be preliminarily carbonized at for example above 800‹ C., the products of distillation being quickly swept away, such as by the passage of practically inert gases. The activating gases specified are steam, preferably superheated, carbon dioxide, air, oxygen, hot burning gases and gases cf combustion, carbon monoxide, hydrogen, generator gases and oxidizing gases. Chlorine and sulphur dioxide may be used to remove inorganic impurities. A hori- or vertical retort may be employed. In an example the process is applied to charcoal granules the heating of the retort being internal, external or both. A series of retorts or of zones may be employed, in which there are introduced different activating gases and in which are maintained different temperatures. The Specification as open to inspection under Sect. 91 (3) (a), describes also the application of the process to the regeneration of spent charcoal, the action of the gases being limited to the secondary carbon. The vertical retort described in Specification 189,148 is referred to as a suitable apparatus. Anthracite and the less porous kinds of coal are also specified as raw materials.

Title: Method of and apparatus for the production of butter
IPC: A01J15/00
Filed: 1928-10-06
Abstract: 323,546. Siedel, J. Oct. 6, 1928. Butter.-For making butter, cream of high fat content is cooled to a temperature between, say, 2‹ and 10‹ C. and is spread or swept in a uniformly thin layer over a surface, without aeration of the cream during butter formation. For batch treatment the cooled cream may be placed in a vessel a, Fig. 1, wherein reciprocates a broad member or sweep k of external shape conforming to the contour of the inside of the vessel so that during the movement of the sweep the cream is gently spread over the bottom of the vessel. The sweep is carried by a frame. adjustably secured by bolts i to the shaft f which is fitted at its outer end with a crank handle. In making the butter, for the final stages of the process the distance between the sweep and the vessel bottom is increased by adjustment of the frame on the bolts. The butter so obtained can be salted and worked up. Instead of employing a moving sweep the vessel may be arranged to be moved, or two hollow cylinders disposed coaxially may be employed. In the continuoustreatment apparatus shown in Fig. 3, cream passing out through openings q from a supply pipe p is thrown outwards by centrifugal force along the surface of a rotating body L and is spread between the corespondingly coned faces m, r of this body and an upper fixed or rotating body n. The bodies l, n may be made hollow for the reception or passage of a cooling medium such as water or brine.
