Patent GB-379892-A (GB)
Title: A process for the production of foams
IPC: A01N25/16
Filed: 1931-10-09
Abstract: A process for the production of foams consists in bringing together at the place of application of the foam components of salve-like consistency containing respectively a substance capable of evolving a gas and a substance which will cause the evolution. The material to which the salve-like consistency is due may be tragacanth or the like.  The gas-producing components may be, for example, a salt such as sodium bicarbonate and an acid such as tartaric acid or an acid salt such as aluminium acetate for producing carbon dioxide, sodium sulphide and tartaric acid for producing sulphuretted hydrogen, sodium nitrite and tartaric acid for producing nitric oxide, sodium nitrite and hydroxylamine hydrochloride for producing nitrous oxide, calcium hydroxide and ammonium chloride for producing ammonia. Oxygen or sulphur dioxide may be produced together with carbon dioxide by suitable additions, for instance pyrolusite and the material known under the registered Trade Mark "Perhydrol" to produce oxygen and an addition of sodium bisulphite to produce sulphur dioxide.  The salves should contain sufficient water for the necessary reaction to occur.  Strong acids or pure alkali carbonates are unsuitable as components as they disintegrate the salve and have injurious effects on the body.  A mixture of sodium carbonate and bicarbonate is however suitable.  As alkali carbonates tend to make the salves viscous agar may be added to prevent this effect. The foams are useful for exterminating pests on the bark or in the wood of trees by means of the evolved gas or an added active substance, or for heating wounds or body cavities in medicinal and veterinary practice.  A preparation for exterminating tree pests consists of the components: A, a salve comprising tragacanth in glycerine and water into which sodium carbonate and bicarbonate are stirred, and B, a salve having the same base as A mixed with tartaric acid or aluminium acetate and nicotine sulphate.  Instead of the alkali carbonate and bicarbonate liver of sulphur may be used.  For use as a medicine a component such as A is used with a component similar to B but with iodoform or bismuth subgallate substituted for the nicotine. Emulsions of fatty, oily and like substances may be used alone or in association with tragacanth albumen, starch, saponin, gums, &c. as the basis of the salves.  Devices for bringing the components together may consist of rigid containers arranged side by side with a duplex piston or of collapsable tubes having compartments side by side, one within the other or centrally divided and discharged simultaneously by pressing the bottom of the compartments by a suitable key device. In the case of containers having separate openings a bifurcated inset tube is used to direct the two components to the place of application.

A cupping press comprises a crank-operated ram device consisting of an inner ram carrying a forming plunger and also a number of cylinders on which pistons are movable against pressure fluid and an outer ram which includes a number of piston rods connected with said pistons and carrying a blank holder, the said piston rods and blank holder being movable with the inner ram during the first part of the working stroke of the ram device but being movable with respect to the ram device against the action of the pressure fluid when the blank holder engages a blank or sheet being worked. The press comprises a slide movable in guides 1 by means of a crank (not shown). The slide has an inner ram 2 carrying a forming plunger 2a and is surrounded by an outer ram constituted by piston rods 6 attached to a blank holder 3 the pistons 5 .(Fig. 2) of said rods working in hydraulic cylinders 4 carried by the inner ram. In operation, when the blank holder contacts the blank on the lower die of the press (not shown) the pistons move upwards, against the fluid pressure in the cylinders which can be regulated by a control valve the setting of which is adjustable. A device for adjusting the control valve comprises a spring - loaded pressure - controlling spindle 11 (Fig. 5), supported in an adjusting nut 13 screwed into an adaptor 14, said nut bearing on a collar 15 on the spindle so that the pressure setting of the valve is manually adjustable. The outer end of the spindle is rounded to form a cam-follower 17 which engages an adjustable cam track 18 on the downward movement of the slide to move the spindle against the spring 12 and so progressively close the control valve to increase pressure on the blank. During the return stroke dogs, or arrester rods (not shown) engage the blank holder to position it for the next working stroke. Oil reservoirs 21 maintain the level of liquid in the cylinders 4. In a drawing press (Fig. 6) fluid pressure cylinders 22 are clamped to both sides of a reciprocating dieholder 23 and'the piston rods forming the outer ram are attached to a pressure plate 24.
