Title: Improvements in and relating to nasal masks for respiratory appliances
IPC: A62B18/02
Filed: 1939-12-08
Abstract: 551,609. Respiratory masks. BOOTHBY, W. M, BULBULIAN, A. H., and LOVELACE, W. R. Dec. 8, 1939, No. 31817. Convention date, July 28. [Class 81 (ii)] A nasal mask comprises a semi-rigid casing providing an open-sided chamber 16 for receiving the nose of the wearer having bulges 15a at the sides immediately below the portion engaging the bridge of the nose so as to provide a substantially free space between the inner wall of the chamber and the whole of the nose and marginal portions comprising bevelled faces 24 for engaging the bridge and sides of the nose and which extend into bevelled faces 27, 28, 29 which flare outwards for contacting the fronts of the cheeks and the upper lip; the chamber is spread laterally at its lower end from the corners of which side tubes 46, 47 extend, diverging downwards and rearwards and then curving forwards with respect to the frontal plane of the mask to engage the face of the wearer at the sides of the mouth while a transverse portion 52, uniting the forwardly curving parts of the side tubes, has a vertical bearing surface 52a for engaging the front of the chin of the wearer so that there is no tendency for the rebreathing bag 59, connected to a tube 53 extending centrally from the portion 52, to move the mask out of position. The tube 53 is connected to the bag 59 by a connector 54 having a boss 60 with escape ports 64 beyond a valve seating in the boss closed by a spring-pressed check valve 63; a tube 65 connected to a source of oxygen extends through the connector 64 and carries a rubber tube 67 which extends to near the bottom of the bag and air may be admitted to the bag through holes 69 in the connector, the number of holes open to the air being adjusted by an apertured sleeve 70 rotatably mounted on the connector. The bag may have folded sides provided with snap fasteners so that the effective volume of the bag may be adjusted. The straps by which the mask is secured to the head of the wearer are connected to metal plates secured to the sides of the mask with spring fingers engaging the sides thereof near the margins of the chamber 16. Specification 551,608 is referred to. Reference has been directed by the Comptroller to the Proceedings of the Staff Meetings of the Mayo Clinic 13 (U.S.A.) dated Oct. 12th, 1938 and The Journal of Aviation Medicine (U.S.A.) Dec., 1938.

Title: Improvements in or relating to endless conveyors
Inventor: JEFFREY ERNEST HAROLD KENNETH
IPC: B65G39/20
Filed: 1956-10-19
Abstract: 855,070. Endless conveyers. BRITISH WEDGE WIRE CO. Ltd. April 10, 1957 (Oct. 19, 1956], No. 31822/56. Class 78 (1). In an endless belt, band, chain or slat conveyer a roller chain is mounted independently of the conveying element to run idly between and with its rollers in contact with a side edge of the conveying element and a stationary guide member, the rollers of the roller chain being arranged with their ares normal to the plane of the conveying element. As shown, the conveyer comprises a wire mesh band 10 adapted to traverse a 180 degree arc. The upper run of the band 10 rests on a series of tapered rollers 13 and has its inner side edge in contact with rollers 14 of an endless roller chain 15 running idly over a guide rail 16. The lower ends of the roller spindles of the chain 15 slide along a track 20 of anti-friction material such as " Tufnol " (Registered Trade Mark). The return run of the chain 15 is enclosed in a housing 21 which includes a shroud 23 to protect the operative run of the chain. The lower run of the band 10 rest on pairs of inclined tapered rollers 24, 25 arranged at a greater spacing than the rollers 13. In another embodiment (Fig. 5, not shown), endless roller chains are disposed along a straight conveyer band at positions adjacent to and on either side of a discharge station where material is removed by a transverse scraper, so as to take up the side thrust on the band produced by the scraper.
Patent GB-761972-A (GB)
Title: Knitting method and machine and product thereof
IPC: D04B9/06
Filed: 1952-12-16
Abstract: 761,972. Knitting. SCOTT & WILLIAMS, Inc. Dec. 16, 1952 [Dec. 26, 1951], No. 31875/52. Class 74 (2). The drive to the rib dial 14 is through an epicyclic gear train 62, 60, 58, 56 in which a yoke 68 carrying the planet gears 60, 58 is angularly movable by a cam on the main cam drum, to shog the dial with respect to the needle cylinder. During plain knitting and loop transfer with the yoke against stop 72, the dial needles, constituted by relatively slidable hook and cast-off members 16, 20, are over inactive cylinder needles 4<SP>11</SP>, and dial fins 15 are over plain sinkers 12. During rib knitting, however, the yoke is brought against stop 74, to shog the dial against the direction of rotation of the needle cylinder, until the dial needles 16, 20 are immediately in front of active cylinder needles 4<SP>1</SP> (in the direction of rotation of the needle cylinder) and the fins 15 are substantially over needles 41 as in Fig. 6. The dial needles are now further than the active cylinder needles 4<SP>1</SP> from sawtooth sinkers 6 therebetween and the needles 41 lead on the dial needles in loop drawing. The total effect of this relative disposition of parts is shown in Fig. 13, in which the sawtooth sinkers have engaged the so-called sinker wale bights 88<SP>1</SP> (instead of dial needle loops 80<SP>1</SP>, as in the normal layout) and enlarged them slightly (instead of the dial needle loops) whilst the dial needle loops 80<SP>1</SP> and cylinder needle loops 821 remain of approximately their original size. Since, however, when the fabric is relaxed, the sawtooth " sinker " loops stand approximately normally to the fabric faces, the cylinder needle loops are substantially in contact on one face of the fabric and the dial needle loops are similarly arranged on the other face; and elasticity is imparted to the fabric, on stretching, by distortion of the sawtooth sinker loops to directions more nearly parallel to the fabric faces. The relative positions of the knitting elements and the direction of shogging may be reversed, the dial needles knitting close to but behind active cylinder needles. The hook members 20 have outside cast-off points 22. The dial is automatically vertically movable, being raised in welt formation, lowered for rib knitting and raised again after loop transfer. Specification .196,124, [Class 74 (ii)], is referred to.

Abstract: 735,012. Ammunition projectiles. ANSTALT FUR DIE ENTWICKLUNG VON ERFINDUNGEN UND GEWERBLICHEN ANWENDUNGEN ENERGA. Nov. 19, 1953 [Dec. 19, 1952], No. 32143/53. Class 9(1). A hollow-charge projectile having a fuze 1 mounted in the head 2 which is secured to the body 3 closed by the base 4, is provided with a rotatable driving band 5. The band 5 is housed in an annular recess between the body 3 and the base 4, at least one washer being placed between the band and a wall of the recess, whereby only part of the angular velocity given to the band by the rifling of the gun is transmitted to the projectile. Projections 7, 8 of the band are adapted to engage the rifling of the gun. In a modification, Fig. 2, a ring 11 and two washers 9, 10 are interposed between the band and its housing, the ring 11 being free to slide, so that the driving band is freely mounted. The cartridge case 12, which abuts the projection 8, is crimped on to a ring 14 housed in the base 4 of the projectile to form a fluid-tight seal. Another modification shows the driving band fixed in a metallic ring which is rotatably housed in the wall of the projectile. Gas-escape passages in the projectile casing are provided near the driving band. The band may be of ductile material, e.g. copper, graphite, antifriction alloys, or of agglomerated fibres or leather. For sub-calibre projectiles the driving band is rotatably mounted in a segmental sabot or ring rigid with the projectile until it leaves the gun. The projectile contains a hollow charge 17 fitted with a metal liner 18 and is provided with stabilising fins 19. For a projectile stabilised by slow spin, Fig. 5, a carrier ring 5a, to house the rotatable driving band 5, is placed against one or more washers 20 and a securing ring 21 is then screwed on to the base. By tightening the ring 21, the degree of friction between the surfaces may be regulated. Openings 22 in the ring 21 allow the propellant gases to press against the carrier ring.
