Title: Improvements in combined valve and coupling
IPC: F16L37/127
Filed: 1931-04-20
Abstract: 383,633. Pipe couplings. HUNT, N. C., 1883, East State Street, Salem, Ohio, U.S.A. April 20, 1931, No. 11695. Convention date, April 25, 1930. [Class 99 (i).] In a combined valve and pipe coupling for pressure air or water lines, wherein the pipe coupling comprises jaws 62 pivoted at 62<1> to a valve body 40 and having hooks 63 fitting a groove in the hose connection member 48, and the valve comprises a sleeve 51 movable axially on the valve body to " on " and " off " positions, the end of the valve sleeve when in the " on " position Fig. 2, underlies the ends 70 of the jaws 62 and prevents them from being opened. The sleeve 51 carries ears 71 which on rotating the sleeve through 90‹ follow the cam-shaped ends 70 of the jaws and cause the sleeve to move to the " off " position where the jaws still remain locked until the sleeve is rotated through a further 90'. The valve comprises a dividing wall 42 with byepass openings 43 at each side which are put into communication by a groove 54 in the sleeve 51. In the " off " position the sleeve is stopped by a shoulder 49 and the exhaust openings are uncovered so that the exhaust side bleeds to the atmosphere. A shoulder 50 forms a stop for the " on " position. At each side of the groove 54 there is a groove housing a U- leather 57 having bevelled edges subject to the pressure fluid in all positions so that the valve stays in whatever position it is set independently of vibration &c. The byepass openings 43 are bevelled or burnished at their outer ends to prevent damage to the U-leathers. In the coupling for an air line, Fig. 2, the body carries a U-shaped leather sealing cup 65 attached to its end by a protecting and aligning nut 66 having one or more apertures 68 so that the washer is pressed by the fluid against the inner surfaces of the coupled parts 40, 48, to form a leak-proof joint. The valve body also has an annular end projection 46 received in a recess in the hose connection member 48. In the water-line coupling the screw 66 and leather washer 65 are omitted, there being a rubber sealing tube projecting from a recess in the valve body and pressed direct by fluid pressure against the coupled members. The hose connection 48 and pipe connection 41 may be transposed or both connections may be either for hoses or pipes. The Specification as open to inspection under Sect. 91 (3) (a) describes also a simpler form wherein the clamping jaws 62 are omitted, the hose connection 48 being directly screwed into the valve body and the pipe connection 41 being integral therewith. This subject-matter does not appear in the Specification as accepted.

Filed: 1955-04-27
Abstract: 769,752. Protective cut-out arrangements; electrically released switches. FKG F. KESSELRING GERATEBAU AKT.-GES. April 27, 1955 [April 29, 1954], No. 12168/55. Addition to 748,532. Class 38(5) In a protective arrangement having a current limiting fuse 23 of low rating and a very rapidly acting switch shunting the fuse, the discharge of a condenser 8 fuses a wire 91 to cause the evaporation of an insulating medium 92, e.g. oil, fat, water or glycol, so that the pressure produced acts on a diaphragm 93 to impart a thrust to an insulating rod 10. The rod 10 acts on the movable contact 21 to fracture a latch 22 of impregnated paper or ceramic or glass-like material and to assist in accelerating the contact which is opened under the bias of a spring 24. The arrangement may be used for ordinary overload protection as in the main patent, but in the arrangement shown protects a contact rectifier 4 against excessive reverse current when a "backfire" occurs. In that event, the current impulse produced in the secondary winding 52 of a premagnetized transformer 5 breaks down a multiple electrode pre-ionized spark gap 7 to permit the condenser 8 to discharge through the wire 91, the condenser being normally kept charged by a transformer 82 and rectifier 81.

Title: Improvements relating to the production of aldehyde-amine condensation products
IPC: C08G12/08
Filed: 1926-05-12
Abstract: 275,725. Light, L. May 12, 1926. Formaldehyde-amine condensation products.- Resinous products are obtained by condensing formaldehyde with a primary aromatic amine in equimolecular proportions in the presence of acetic or hydrochloric acid. The necessary proportion of acid and the necessary conditions of temperature are indicated by an example in which aniline is mixed with 10 per cent by weight of glacial acetic acid or 0.4 per cent by weight of concentrated hydrochloric acid and the mixture is heated to 70‹ C., whereafter an equimolecular amount of formaldehyde is slowly added with brisk stirring while the stated temperature is maintained. The mixture is then heated for several minutes at 90‹ C. On cooling, there is obtained a pale yellow or brown resinous material, softening at 25‹ C., which, by heating at 90‹ C. for half an hour, is converted into a transparent yellow resin softening at about 35‹ C. By further heating at a temperature slowly rising to 190-200‹ C., the softening point of the product is raised to about 70‹ C. The heat.-treahed products are converted into brown opaque resins by treatment for a few minutes with boiling water. Specifications 1963/95 and 240,407 are referred to.

Abstract: 567,255. Gas - blast switches. FLURSCHEIM, C. H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. July 28, 1943, No. 12297. [Class 38 (v)] A gas-blast switch of the kind having at least one pneumatically - actuated contact, has a fixed contact 1 of nozzle form extending through a condenser-type, or other insulating bushing 4 at one side of a metal chamber 3, the other side of which carries, or is formed as, a cylinder 6 from' which the movable nozzle contact 2, together with its piston 2a, spring 9, and rubbing contact 8, can be removed by removing the end plate 7 and silencer 14. The fixed contact 1 can be removed by removing washer 4a. Chamber 3 has an aperture 47 closed by' a cover 48 and an aperture 11 receiving the blast pipe 12 in the supporting insulator 10. A pair of such structures may be assembled in such a way that external contacts on the chamber 3 may be bridged by a horizontallyrotatable isolator-arm on a post-insulator, Fig. 2 (not shown), or, Figs. 3, 4 (not shown), external isolating contacts on the ends 1b may be separable by bodily rotation of the two structures in opposite directions in a horizontal plane. Fig. 6 shows how two (or more) structures may be assembled one over the other with an additional hollow insulator 40 (which may, however, be dispensed with), the chambers 3 being directly in contact, Fig. 7 (not shown). The lowest chamber 3 may have an external contact co-operating with a rotatable isolatorarm, Fig. 5 (not shown). The terminal 1b of unit -A is connected at 41 to chamber 3 of unit B, and so on for succeeding units, but the units may be alternately oppositely-directed with the member 1b of the lower unit connected to member 7 of the unit above it. The cover 48 of unit A of Fig. 1 is replaced by a flanged annulus 53 supporting insulator 40 and both chambers 3 are flanged at 50 so as to locate a continuous tube 12 which is apertured at 55, 56 to accommodate the contacts and admit the blast gas. The lower end of 12 is threaded on to a metal sleeve 57 in a ring 52 on the storage tank or other base 51, whereas the upper end screws into a metal cap 60 in a ring 61. The member 12 is thereby held in tension and insulators 10, 40 in compression, the latter being preferably of ceramic material and the former of vulcanite or paper coated or impregnated with synthetic resin. Insulators 10, 40 may be adapted to provide capacity-grading of the breaks, or formed of high dielectric-constant material such as rutile. In Fig. 8, the cylinder 70 of movable contact 2 is mounted in an nsulator 71 which is removably secured by a ring 75 to chamber 3. The fixed contact 1 in this Figure and Fig. 1 may be replaced by a movable one. Several pairs of contacts may be arranged in a common metal chamber and connected in series by externally-located conductors.
