Title: Improvements relating to snap-action electric switches
IPC: H01H3/00
Filed: 1949-08-15
Abstract: 666,668. Snap-action switches. ALLDAY & SON (1922) Ltd., H., and BAIN, R. Aug. 3, 1950. [Aug. 15, 1949] No. 21165/49. Class 38 (v). A switch comprises a contact-carrying arm f loosely mounted on a spindle d and having a projection g, a projection k parallel thereto and fixed to a plate j secured to the spindle, and a coiled spring m having its ends n embracing the projections g, k, the projection k being integral with a piece v having shoulders arranged to engage the projection g for positive actuation of the arm f if the spring fails. The arm f, which insulatingly carries a contact piece h, is held in its limit positions against stops s by pivoted catches o which are urged together by a spring p, the appropriate catch being released by a cam r on the spindle, when the latter has been turned sufficiently to strain the spring m which then urges the arm f to its other position where it is held by the other catch. The fixed contacts t are arranged in arcuate slots u in the base piece a.

Abstract: 738,915. Casting processes ; continuous - casting machines. EISENWERKE GELSENKIRCHEN AKT.-GES. Aug. 4, 1953, No. 21516/53. Class 83 (1). In a method of continuously casting socketed tubes &c. wherein an outer socket mould 4 and a socket core 5 are moved in the direction of the casting axis in the formation of the stem portion of the tube, the socket mould and core are of metal and are moved relatively to one another in the direction of the casting axis independently of one another immediately the casting material of the inner face of the socket has solidified. The stationary continuous-casting mould 1 and mandrel 2 are of metal and watercooled and the socket mould and core may be artificially cooled. If the socket is internally screw-threaded the axial movement of the core relative to the socket mould is accompanied by a simultaneous rotation of the core. If the tube portion solidifies before the socket portion the socket mould and core are moved together until the faces of the socket have solidified, and then the core is moved more rapidly until it has been freed from the socket, the socket mould and core being then moved again at the same speed.

Title: Improvements relating to the manufacture of laminated fabric garments
Inventor: WOOD REGINALD
IPC: A41B3/10
Filed: 1958-07-07
Abstract: 910,307. Stiffening collars, cuffs &c. BRADFORD DYERS' ASSOCIATION Ltd., and HOGG & MITCHELL Ltd. July 7, 1959 [July 7, 1958], No. 21704/58. Class 141. [Also in Group VIII] A smart appearance is imparted to a garment or part thereof, e.g. a collar, of laminated construction by interleaving the laminate over one or more areas with a sheet or film of watersoluble adhesive and then damping and hot pressing the laminµ to partially dissolve the adhesive and cause it to flow into the interstices of the fabric to bond the laminµ together. The adhesive may be stitched in position, and may be starch, gelatin, glue, gum, an alginate, a water-soluble cellulose derivative, polyvinyl alcohol, polyacrylic acid or one of its salts; the preferred material is naturally-occurring rice paper. Optional additions to the adhesive layer are: (1) hydrotropic or dispersing agents, e.g. a sodium alkyl sulphonate, (2) a lubricant or softening agent, e.g. glycerol, emulsions of polyethylene or silicones, fatty substances such as derivatives of stearic acid or cetyl alcohol and stearamide-modified condensation resins. The adhesive layer may be fixed or rendered insoluble e.g. by forming a water-insoluble resin in it before or during the damping and hot-pressing operations. The fixing agent or its constituents may be present on one or both of the fabrics with which the film of adhesive is in contact or may be applied separately, e.g. in the damping operation, or may be incorporated ir the adhesive sheet. In the examples, solutions of (1) dimethylolurea and ammonium dihydrogen phosphate, (2) formaldehyde and phosphoric acid, and (3) water only, were sprayed on to pieces of cotton poplin; in each case, pieces of the treated poplin were placed on either side of a piece of rice paper and ironed to dryness. In the first two cases, the layers remained bonded when washed, but in the third case they separated on washing. The invention is stated to be applicable to the stiffening of either the collar top or band portion of a collar, the collar band of a collar-attached shirt, the neckband of a tunic shirt, shirt cuffs and blouse fronts.

Title: Methods of producing water-soluble colloidal molybdenum
IPC: B01J13/00
Filed: 1935-08-02
Abstract: Stable colloidal molybdenum solutions, particularly suitable for medical purposes for the treatment of coccogenic infections, are obtained by reducing a water suspension of molybdenum oxides containing a non-toxic water-soluble protective colloid such as gum arabic or gelatine by means of formaldehyde-sodium sulphoxylate, at a temperature of about 100 DEG  C.  Colloidal molybdenum may be precipitated from this solution by solvents such as alcohols, acetone, alcohol and ether or alcohol and acetone mixtures, or the solution may be evaporated to dryness.  The product is an amorphous substance, grey to black in colour, and is readily soluble in hot water.  Excess of formaldehyde-sodium sulphoxylate is removed by washing with alcohol or alcohol and ether, but it is desirable to allow it to remain in the product, since it is non-toxic and prevents oxidation.  The products of oxidation of formaldehyde-sodium sulphoxylate (due to exposure to air) are also non-toxic and protect the colloidal molybdenum from oxidation.  The aqueous solution may be used for subcutaneous and intramuscular injection when fresh or kept sealed.  The dry product is stable and may be used after a period of time.ALSO:Stable colloidal molybdenum solutions, particularly suitable for medical purposes for the treatment of coccogenic infections, are obtained by reducing a water suspension of molybdenum oxides containing a non-toxic water-soluble protective colloid such as gum arabic or gelatine by means of formaldehyde-sodium sulphoxylate, at a temperature of about 100 DEG  C.

[Also in Groups XXII and XXIII] In the cutting or piercing of a body of refractory material, such as stainless steel, slag, concrete, brick, by an oxygen lance comprising a ferrous metal pipe P which is supplied with oxidizing gas and a combustible adjuvant powder, the adjuvant powder is introduced into the pipe after the flow of oxidizing gas has been initiated, and is stopped before the oxidizing gas is shut off so as to purge the pipe P of powder and avoid pre-ignition. The pipe P of iron or stainless steel is secured by a coupling K and an adaptor 20 to a handle H carrying a valve body 16 and a single valve operating lever L. Oxygen is supplied through an inlet 18 and a valve C, Fig. 4 not shown) to a pipe 14; the adjuvant powder, comprising a mixture of iron and aluminium, is supplied through an inlet 26 and valve V, Fig. 3 (not shown) to a pipe 24 extending co-axially into the pipe P Depression of the lever L first opens the oxygen valve and then the powder valve and upon release of the lever the powder valve closes before the oxygen valve. The oxygen-powder mixture issuing from the end of the pipe P is ignited by directing it against a piece of smouldering cloth or wood. The lance may be used for flame desurfacing without the ferrous pipe being consumed. Examples are given of the preferred composition of the powder, the oxygen and powder pressures used and the dimensions of the pipe P
