Title: Improvements in or relating to fluid flow control valves
Inventor: TRUSLOVE DAVID JAMES
IPC: F16K13/10
Filed: 1963-02-20
Abstract: 1,037,074. Valves. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 5, 1964 [Feb. 20, 1963], No. 6848/63. Heading F2V. [Also in Division G3] A one-way valve, i.e. a valve which permits gas flow in one direction with no substantial pressure drop and prevents or severely restricts reverse flow, consists of a tapered-cylindrical cavity 11, Fig. 1, with the wider end 12 of hemispherical shape but extended by a meniscus-shaped space 13; the end 12 is connected to the opposite or narrow end via a by-pass 21 whilst ducts 15, 16 open into the opposite ends of the cavity 11. A globule of liquid, e.g. mercury, which is disposed in the cavity has such a volume that it assumes a stable spherical-shape under surface tension and occupies the entire cross-section of the wider end 12 of the cavity. If the globule is displaced to the right it is distorted and the forces of surface tension tend to restore the globule to its initial position and shape and so act as loading means. When fluid pressure is admitted to duct 15 it displaces the globule to uncover the by-pass port 23 so that fluid flows to the duct 16. Reversal of flow causes the globule to seal the port 23; if the pressure is very high the globule is forced into the duct 15. The cavity may be of rectangular section and the by-pass duct may be formed by ducts in the cavity wall. The cavity may be restricted beyond the rest position of the globule. In a modification, the by-pass is formed by a tapered-porous plug, the device consisting of two porous elements A, B (Fig. 4, not shown), with a tapering cavity therebetween which houses a further porous member C forming a guide for a globule, the member C having a larger pore size than that of the other two elements which are of the same material and have the same pore size. The globule moves readily in the member C but requires the application of high pressure to be conducted in either of elements B, C. The member C enables liquids of low surface tension to be used; if the element C is omitted then liquid with high surface-tension may be employed.

Title: Improvements in automatic adjusting devices
Inventor: BUTLER HENRY JAMES
IPC: F16D65/18
Filed: 1956-03-09
Abstract: 850,649. Friction clutches. DUNLOP RUBBER CO. Ltd. March 4, 1957 [March 9, 1956], No. 7003/57. Divided out of 850,648. Class 80 (2). [Also in Group XXXIV] In an automatic adjusting device for brakes, clutches or the like, a close-coiled spring wired helix 23 is secured to both piston members 12 of a spot-type disc brake illustrated and a pin 33, having a limited axial movement relative to the end of 14 of each cylinder member 10, is held in frictional engagement with helix 23 whereby upon relative movement between the piston member. 12 and the cylinder member 10 the device is adapted to move in unison therewith through the limited axially movement and upon further relative movement between the members relative movement also takes place between the helix and the pin. The normal clearance of the brake pads 18 with the braking surfaces of the brake disc 1 is governed by the distance 35 between the surface of flange 30 of inset member 27 and the Belleville washer 32 when in the curved position illustrated in the Figure. When fluid under pressure is admitted to spaces 13, pistons 12 and friction pads 18 are forced to the adjacent friction surfaces of the disc 1 to apply the brake. If the clearance between the friction pads 18 and the disc 1 is equal to, or less than, the axially depth of the spaces 35, movement of the pistons 12 and their associated friction pads 18 towards the disc 1 will cause the pads frictionally to engage the disc before, or at the same time as, the spaces 35 are eliminated by axially movement of the pins 33 in unison with the pistons 12 and the consequent flattening of the Belleville washers 32 against the flanges 30 by the heads 34 of the pins 33. Should pad wear take place relative movement will take place between the pins 33 and the members 23 to ensure that brake clearance remains constant in the inoperative state of the brake. Folded annular rubber sealing members 20 are provided, not only to act as dust and dirt shields for the open end of the cylinder, but possess sufficient resilience to tend to force the piston against the hydraulic head of liquid in the system when the brake is inoperative. Reference has been directed by the Comptroller to Specification 747,965.

Title: Latex base for surface coating compositions
IPC: C08F220/18
Filed: 1959-03-02
Abstract: A latex comprises an interpolymer of a styrene monomer, a C5 to C20 alkyl acrylate or methacrylate and a cross-linking agent having 2 or 3 unsaturated groups.  Optionally the interpolymer comprises a stabilizing monomer selected from acrylic or methacrylic acid and monoalkyl esters of dicarboxylic acids.  The styrene monomer may be styrene, vinyl toluene or a -methyl styrene, and the crosslinking agent may be any one of many specified esters of unsaturated alcohols and/or unsaturated acids, unsaturated ketones or ethers, butadiene, or preferably may be a divinyl benzene or naphthalene.  The latex may be prepared by initially polymerizing the styrene monomer in a first emulsifier mixture and then slowly adding the other monomers and a second emulsifier mixture.  In Example I the following polymerization ingredients are used; water, sulphuric acid, ferrous ammonium sulphate, ammonia, emulsifiers, potassium pyrosphosphate and potassium persulphate.  The products find application as coating compositions, e.g. for metal priming.  Pigments and/or fillers, such as titanium dioxide, aluminium silicate and mica, may be included.
Patent GB-841653-A (GB)
Title: Process for the production of dibasic and monobasic acids
Inventor: MAGGIOLO ALLISON
IPC: C07C51/34
Filed: 1958-03-06
Abstract: Mono- and di-basic acids are prepared from oleic, linoleic or erucic acid or mixtures thereof by ozonizing the unsaturated fatty acid in an inert solvent with an ozone-containing gas in the presence of an amount of water in the approximate range of one to six times the weight of unsaturated fatty acid and solvent whereby the temperature is maintained without other cooling at a temperature in the range of approximately 0 DEG  to 49 DEG  C., subjecting the resulting ozonide to oxidative decomposition in the water with a gas containing free oxygen at a temperature from 100 DEG  to 150 DEG C. and then recovering the acids.  The ozonization may be effected with an ozone-oxygen or ozone-air mixture and the decomposition with air, oxygen or preferably an ozone-air or -oxygen mixture.  In an example, a solution of tall oil unsaturated fatty acids (oleic and linoleic acids) in caproic acid is mixed with quantities of water amounting to from 100-600% by weight of the unsaturated acids and solvent and ozonized oxygen is bubbled therethrough until ozonization is complete, the temperature being 30-40 DEG  C., and then the temperature is raised to 100-110 DEG  C. and oxygen containing a lesser amount of ozone is bubbled through.  The product is distilled to remove monobasic acids comprising caproic and pelargonic acids and the residue is boiled with water and azelaic acid recovered therefrom.  In a comparative experiment, the ozonization is effected at 70 DEG  C. in the presence of a minor amount of water, resulting in a lower yield of azelaic acid.  Lower yields are also stated to be obtained when a solution of oleic acid in acetic acid containing 10% of water is ozonized at 60 DEG  C., as opposed to 25 DEG  C. in the presence of water in accordance with the invention, followed by decomposition at 102-105 DEG  C.  Specifications 741,739, 757,355 and German Specification 565,158 are referred to.

Patent GB-1210336-A (GB)
Title: Method of and apparatus for butt-splicing a running web
IPC: B65H19/10
Filed: 1969-02-11
Abstract: 1,210,336. Splicing webs. J. BOBST ET FILS S.A. 11 Feb., 1969 [15 Feb., 1968], No. 7309/69. Heading B8R. A butt splice between an expiring running web 66 and a new web 106 is made by:-preparing the leading edge 56 of the new web 106 with adhesive tape 58 and with a relatively thick build-up strip 62; pressing the expiring web 66 against the adhesive tape 58 and the leading edge 56 of the new web with the build-up strip 62 between the two webs; and disposing a cutter 40 in the path of the build-up strip just clear of the new web 106, whereby the cutter 40 severs the expiring web at the leading edge of the new web and guides the build-up strip and the tail of the expiring web away from the new web (Figs. 11, 12 and 13, not shown). As shown in Fig. 1, a replacement roll 20 having its leading edge prepared with adhesive tape and build-up strip has been moved from a loading position on the right of a turnover stand to the working position on the left, and the working roll 16 has been moved to the right-hand position so that the expiring web 66 passes beneath a lower deflecting roller 24, over a contact roller 30 which is normally in the lower position 30<SP>1</SP>, between ironing rollers 32, 34, the latter normally being in a lowered position, around a cut-off drum 36 which co-operates with the cutter 40 which is normally in a dropped position, between a back-taping roll 42 and a backing roll 44 which are normally separated, over a guide roller 46 and then on to the equipment, e.g. a printing press, being supplied with the web. For the splicing operation roller 30 is raised so that the expiring web 66 is held against the roll 20 until the adhesive-prepared leading edge 56 of the roll reaches the expiring web and the two webs stick together with the build-up strip 62 therebetween; the ironing rolls 32, 34 are then rendered operative so that the expiring web is bent more closely round the build-up strips; the cutter 40 is then raised into a position where it severs the expiring web 66 at the leading edge of the new web, whereby a butt joint is formed between the two webs; and a backing adhesive tape is then applied to the joint by the rolls 42, 44. A suitable electric and pneumatic control system for effecting the splicing sequence is described with reference to Figs. 18 and 19 (not shown). A sensor 160, e.g. of the magnetic or electrical contact type, determines the start of the splicing operation in relation to the rotational position of the roll 2, and a further sensor 162, e.g. of the photoelectric type, co-operates with a projecting end of the build-up strip 62 to determine the operation of the back-taping rolls 42, 44. The lateral position of the roll 20 on the stand 12 may be adjusted by a hand-wheel 52, and the roll 20 is brought up to synchronous speed for the splicing operation by a belt drive 26.
