Title: Improvements in and relating to the blending and dispensing of viscous substances
Inventor: LEWIS-SMITH CHARLES PETER
IPC: B29B7/60
Filed: 1959-05-15
Abstract: 908,519. Mixing viscous liquids in proportions. BAKER PERKINS Ltd. May 12, 1960 [May 15, 1959], No. 16760/59. Class 86. In an apparatus for dispensing in predetermined proportions, and mixing, viscous substances, e.g. an epoxy resin and a hardener, the containers C in which the component materials are delivered are placed over fixed pistons 1 having axial feed bores 5 and pipes 4 communicating with a mixing and dispensing head 6. The containers are forced down over the fixed pistons by thrust from pistons and rods 18, 19, actuated by hydraulic rams 9, the pistons 10 of which have rods hinged to a beam 12 pivoted at 14 and operated by a pneumatic cylinder and pistons 11, 24. The position of the rams 9 in relation to the beam 12 is adjustable to vary the proportion of the two materials supplied. The fixed pistons 1 have domed beads to ensure that all air is expelled when the containers are placed over them. The thrust heads 20 are concave to correspond and the fixed pistons have radial slots to allow material at the periphery of the container to reach the central bore 5. The mixing head 6, Fig. 3, has a body 34 having an outer nozzle 7 and an internal slotted baffle 40 through which passes the end of the mixing and compressing member 35, which has a compressing worm section 42 and a mixing and agitating section 43 having a plurality of blades 44. The mixing member also has a socket adapted to engage the end 46 of a motor-driven shaft 47. Two feed ports 36 are designed to seal with the ends 48 of the feed pipes 4. In order that the mixing head may be readily removable and replaceable, the two component material supply systems, each comprising a container C, fixed piston 1, feed pipe 4 and cylinder 8 are each mounted as units to be pivotal on a shaft 49 (see Figs. 2 and 3, not shown), near the top of the machine and to grip the mixing head between them. When used with materials such as epoxy resins the mixing head may be expandable ; the body 34 may conveniently be a highdensity polythene moulding and the mixing member a nylon moulding or metal die casting.

Abstract: 555,201. Lathes. HEPPENSTALL CO. Dec. 31, 1941, No. 16858. Convention date, Jan. 15. [Class 83 (iii)] A lathe has a tool carriage which is moved by infinitely variable hydraulic gearing driven from the headstock gearing. The headstock spindle 2 is driven from a motor 14 through belt gearing 12 and main shaft 8, provided with a clutch 16. When the clutch is engaged, the spindle is driven from shaft 8 through gears 7, 6 but when the clutch is disengaged and pinion 21 meshed with a gear 22 on the shaft 19 the drive is conveyed from this shaft through gears 18, 17, 7, 6 to drive the spindle at a different speed. The shaft 19 is connected by a belt 31 to a _pump 32 drawing fluid from a reservoir 33 and delivering through a reversing valve 37 to a variable delivery pump 41 which is connected through gears 43 to a lead screw 26 which traverses the tool carriage 23. Thus by altering the pump delivery the carriage feed may be infinitely varied without changing the spindle speed. The valve is reversed or neutralized by movement of a handle 55 connected through linkage to the valve spindle. For obtaining a high speed of the tool carriage without disturbing the pump setting a booster pump 57 in this circuit may be driven when required by a motor 61 controlled by a pushbutton switch 62 on the tool carriage.

Title: Improvements in dyes
IPC: C09B29/08
Filed: 1944-09-11
Abstract: Azo dyes are manufactured by coupling diazotized 6-nitro-2-aminobenzthiazole with a 3-acylamino-1-di-(hydroxyalkyl)-aminobenzene which may be substituted in the 6-position by alkoxy, alkyl, hydroxy or halogen.  The products yield dischargeable blue dyeings on cellulose ester or ether textile materials such as cellulose acetate, propionate, butyrate, acetatepropionate and acetate-butyrate and ethyl and benzyl cellulose, e.g. from a bath containing the dyestuff dispersed by means of a dispersing agent, and also on some other textile materials, e.g. silk and wool. They may also be used for colouring solutions of cellulose derivatives, especially lacquers and spinning solutions, the latter yielding coloured products by shaping and setting in the form of filaments (e.g. by dry spinning), straws or films. Examples describe the production of dyestuffs from diazotized 6-nitro-2-aminobenzthiazole and (1) 1-di-(b -hydroxyethyl)-amino-3-acetanilide; (2) 1-di-(b -hydroxyethyl)-amino-6-methoxy-3-acetanilide, and the dyeing of cellulose acetate fabric with the products.  Other coupling components specified are: 1-di-(b -hydroxyethyl)-amino-6-methyl-, -chloro- and-hydroxy-3-acetanilide, 1 - di - (b  - hydroxypropyl) - amino - 3 - propionylaminobenzene and 1 - di - (b : g  - di - hydroxypropyl) - amino - 3 - acetanilide.  Specification 440,113 is referred to.  1 - Di - (b -hydroxyethyl)-amino-6-methyl- and -6-chloro-3-acetanilide are obtainable by the action of ethylene oxide on, respectively, 2-amino-4-acetylaminotoluene and 4-chloro-3-aminoacetanilide, the latter compound being obtainable by reduction of the corresponding nitro compound.  1 - Di - (b -hydroxypropyl) - amino-3-propionyl-aminobenzene is obtainable by the action of propylene oxide on 1-amino-3-propionylamino-benzene.  1 - Di - (b  : g -dihydroxypropyl) - amino-3-acetanilide is obtainable by the action of glycide on monoacetyl-m-phenylenediamine.
