Title: Improvements in couplings for fluid conduits
IPC: F16L37/34
Filed: 1948-07-06
Abstract: 641,050. Pipe couplings. AUTOMOTIVE PRODUCTS CO., Ltd. July 6, 1948, No. 18177. Convention date, Sept. 8, 1947. [Class 99(i)] A part 1, which may have slidable there-- in sleeves 11a, 11b connected by a screwthread 12. and a part 3 are coupled together by' means, 'such as detent segments 40 radially displaceable in slots 39 of sleeve 11b and engageable in a groove 47 of part 3, which permits separation of the parts upon limited relative axial movement thereof and during such movement the combined volume of a chamber 15, which may be formed between part 1 and sleeve 11a, and the coupling passage remains substantially constant. Valves 5, 6 of parts 1, 3 respectively seal the parts when separated, and a piston 19 of sleeve 11a causes transfer of fluid from the chamber through openings 20 to the passage which is maintained open during movement of the parts. The parts are separated, against the action of spring 42, by the application of a force which causes the part 3 together with the sleeves to move relatively to part 1; the detents being then displaced into a recess 41 of the latter to disengage from the groove of the former: the sleeves are brassed back to their contracted position by the spring and simultaneously there is a now of fluid back to the chamber. Coupling of the parts may be effected by rotating the sleeves relatively to displace flange 43 axially beyond collar 8 inserting part 3 into part 1 and rotating the sleeves oppositely to cam the detents into the groove by an inclined surface 48. Holes 27 communicate with a space 26 to function as an air-bleed, circumferentially spaced pins 13 guide the sliding sleeves and a stop ring 45 of sleeve 11b limits the axial movement.

Title: Knee joint for artificial legs
IPC: A61F2/50
Filed: 1950-07-24
Abstract: 691,264. Artificial legs. TOUSON, I. May 22, 1951 [July 24, 1950], No. 18410/50. Class 81 (ii). A knee joint has parabolically curved coacting surfaces provided with telescopic control means. The joint described comprises working surfaces 1, 2, one of which slides on the other when the knee is bent or straightened. However, as soon as weight is placed on the leg the thigh portion, having a slot 5 passing around a pin 3, tends to turn about the said pin and thereby force the two surfaces into contact to prevent further movement. The action may be cushioned, and the friction increased, by a rubber block 32 carried in the thigh member. In order to assist in returning the leg to the straight position a spring-loaded telescopic arrangement comprising a rod 12 and tube 13 is pivoted between 19 on the thigh portion and a pin 7 on the shin portion. This is urged in a rearward direction by a spring 30, bearing on a nosepiece 29, and an adjustable rubber loop 40.

[Class 83 (iv).] A series of coils of metal are passed through a rolling mill which uncoils and reduces them and recoils them again, the spools then being passed to storage conveyers from which they are transferred and repassed through the mill as often as desired. In Fig. 1 a spool 37<a> is moved from the storage conveyer 37 to a car 113 which is then traversed axially to position in front of rolls 26 and the coil is dragged through the rolls and rewound on an empty spool on the car 52. The car 52 is then traversed until opposite the endless conveyer 35 and the coil and spool is discharged thereon. The empty spool with the car 113 is moved in front of the spool storer 36 and the empty spool is discharged thereon by the hand lever 117. Thus a number of spools with coiled metal thereon is stored on the conveyers 35 and 37, spools being transferred from 35 to 37 by a cross conveyer 92. A number of empty spools is accumulated on the storer 36 from which the car 52 receives an empty spool and moves it up to receive the metal coming from the mill. The metal is coiled on the rotated spool by curved guides 43, Fig. 11, which can be closed around the spool. In Fig. 13, the car 52 receives and grips the empty spool 30 by a lever 63 and the car itself runs on rollers 53 and is advanced and withdrawn by fluid pressure piston or by chains driven by an electric motor 55. The casing 113 in front of the mill has rollers on which the spool flanges rest and rotate while the metal is uncoiled by the rolls of the mill. The empty spool is pushed by the transferring carriage on to a driving drum 27 with a slipping clutch to wind the metal tightly on the spool. The loaded spool is automatically lifted on to the conveyer 35 by a cam. When pushing up an empty spool on to the drum the carriage 38 is stopped automatically by a trip switch. The conveyers 35 and 37 are actuated by electric motors with push button switches. When the requisite number of passes has been completed the metal is coiled on a motor driven winder 104 and then the coil itself is removed and dropped on to a gravity conveyer 107 to a slitting machine &c.

Title: Unsaturated polyester resins and interpolymers derived therefrom
IPC: C08G63/676
Filed: 1959-06-03
Abstract: Unsaturated polyesters having good water-resistance and flexibility are made by polyesterifying an aromatic glycol of formula <FORM:0914522/IV(a)/1> where R is an alkyl or cycloalkyl substituent having from 5-12 carbon atoms and n is an average number lying between 1 and 2, with an unsaturated dicarboxylic acid or anhydride thereof (e.g. maleic, fumaric, itaconic, citraconic or mesaconic acid or anhydride).  Cross-linking of the polyester is effected by treatment with an unsaturated monomer, e.g. styrene; a -methyl styrene; alkyl styrenes (e.g. o-methyl-, p-ethyl- or 2,4-dimethyl styrene); diallyl phthalate; an ester of acrylic or methacrylic acid (e.g. methyl acrylate); acrylonitrile; vinyl pyrrolidone; vinyl pyridine and ethyl vinyl pyridine.  A free radical catalyst is used generated by thermal or photolytic means or by benzoyl peroxide or diacetyl peroxide.  The compositions of polyester and monomer may be used in casting, moulding or laminating operations, if desired with fillers, pigments or dyes such as wood flour, wood fibre, a -cellulose, paper dust, clay, diatomaceous earths, zein, glass wool, mica, granite dust, cotton flock, steel wool, silicon carbide, paper, cloth (e.g. of glass), sand, silica flour, silica white, titanium dioxide, iron oxides or barytes.  They may also be used as adhesives, impregnants or protective coatings or in the production of wire enamels or insulating tapes.  Examples describe the manufacture of a glass fibre laminate (see Group VIII) wherein the laminating resin used is a mixture of styrene and an unsaturated polyester (derived from maleic anhydride and a glyrol as above wherein R is a tertiary octyl group derived from diisobutylene), catalysed with benzoyl peroxide.

Class 92(2) Relates to automatic firearms. of the kind which recoils in a cradle on firing and which has a plurality of cartridge chambers in a rotary drum. According to the invention the electric firing pin 14 is arranged in the gun casing 2 and is retracted to a position clear of the drum 3 by mechanism controlled alternately by the rotation of the drum and the recoil of the casing. In the gun shown the casing 2, and with it the barrel 1, recoil with respect to a cradle 22. During the recoil and the subsequent return movements a fresh round from a feed star wheel 9 is introduced into one of the chambers of the drum 3 by a slide 4 actuated by a gas-piston 6 as discribed in Specification 686,654. The firing pin is surrounded by insulation 31, is pressed into a spring-controlled sleeve 15 in the casing 2, and makes contact with a contact pin 20 mounted in the nose 19 of the cradle 22. When the casing 2 recoils a three armed lever 18, pivoted thereto, is rocked by a surface 29 on the nose 19 thus causing another arm of the lever to retract the firing pin to a position clear of the drum 3 against the action of the spring 16 of the sleeve 15. The drum is then rotated by a groove in the slide 4 to bring another chamber into line with the barrel, and during this rotation a lever 21, pivoted on the casing, is rocked by the undulating surface of the drum to a position where its nose 25 engages the third arm of lever 18 to hold the firing pin retracted until the drum has completed its movement. Upon such completion the lever 21 is rocked by the lever 18 to its original position shown while the firing pin returns to the firing position.
