Title: Pressurized housings for diving equipment
IPC: B63C11/14
Filed: 1974-06-10
Abstract: 1478342 Diving equipment: helmets GENERAL AQUADYNE Inc 10 June 1974 25597/74 Heading B7U Equipment such as a light or a camera is mounted within a housing which is maintained at the same pressure as the air supplied to a diver's face mask or helmet by an air pipe. The housing may be mounted on top of a diving helmet or strapped onto a diver's head or another part of his body. In a first embodiment a wet helmet is pivotally secured by headed pins 12 to a face mask 10 and includes a housing compartment 18 having a window 19 through which passes light from a bulb 21. The housing is pressurized by a tube 23 connected to a pressure regulator 31 by a self sealing coupling which seals upon withdrawal of an elbow on the end of tube 23. A power cable 24 passes through the tube 23 and the bulb 21 is turned on/off by a switch 48 suitably located for manual operation by the diver. A video camera maybe located in housing 18 instead of the bulb 21. Alternatively a housing is strapped onto a diver's head and an air pipe is connected between it and a face mask. In a third construction (not shown) a diving helmet has a housing on top whose interior is connected to the housing by an air pipe.

Abstract: 638,648. Blowing glass. CORNING GLASS WORKS. Sept. 23, 1947, No. 25863. Convention date, Oct. 15, 1946. [Class 56] Relates to a -fully automatic machine for blowing hollow glass articles such as bottles, light bulbs, tumblers and lamp chimneys. A charge of glass is sheared by oppositely rotating knives 207, 208, Fig. 1, and is initially positioned between holders 240, 250, Fig. 16, whilst they are in the dotted line position, the holders being supported on carriages 242, 255 simultaneously movable in opposite directions. The holder 250 is pivoted on an arm 252 rockable through 90 degrees about a pivot 271 on the carriage 255 and is provided with telescopic guides 268, 288<SP>1</SP> one of which is pivoted to a fixed arm 269, whereby on the arm 252 being swung from the vertical to the horizontal position the holder 250 is moved from an inwardly facing to a downwardly facing position, the charge being held to the holder 250 by suction during such movement. When the holder arrives at its downwardly facing position compressed air removes the charge which is delivered on to an orificed plate 61, Fig. 1, in the loading position of a ring turret 14 which is intermittently rotated step by step. The plate 61 carrying the charge is, during movement of the turret, pushed by a reciprocating pushrod 100 into one of a number of blowhead assemblies 50, Fig. 2, carried by a blowhead turret 13 constantly rotating within the ring turret 14. Turret 13 is provided with split moulds 26, 27 which are closed and opened at appropriate times during the movement of the turret by a pneumatic power unit 30 the control valves of which are actuated by cams. Before the moulds close puff air is admitted into the charge to expand it partly and after the moulds have closed blow air is admitted to complete the blowing, the air being admitted from puff and blow boxes 136, 137, Fig. 1, under the control of valves operated automatically in sequence. The glass is rotated during the puff and blow steps. After the moulds have opened the orifice plate carrying the substantially completed article is retransferred to the outer turret 14 by a reciprocating pusher 155, Fig. 2, and the article is cracked off at the orifice in the plate by an assembly 325, Fig: 1, and the cullet above the orifice plate is removed and directed to a shoot. Specification 532,888 is 'referred to.

Abstract: 1,003,162. Spring drums. M. V. BLAKE. July 1, 1963 [July 6, 1962], No. 26078/62. Heading B8B. [Also in Divisions A3 and F2] A spring drum for the strap of a safety harness comprises a braking device consisting of bouncing putty or other visco-elastic material between two relatively rotatable elements. The drum 11 for the strap 10 is rotatable on spigots 20, 22 mounted in bearings in end plates 17, 18 of a housing 16 and a coil spring 23 is anchored on the spigot 22 and a cover-plate 13. The drum houses a cylindrical chamber 30 containing bouncing putty 31 and a stirrer 33, the shaft of which passes through the spigot 20 and is resiliently held by one arm 34 of an L-shaped member which fits into the end of the stirrer shaft. A spring 37 connects the arm to the arm 39 of a similar L-shaped member which locks into the bore of a pawl 41. When the strap 10 jerks the bouncing putty stiffens and locks with the stirrer which rotates slightly so that the pawl engages a ratchet 21 on a cover-plate 12 and arrests the drum. With the stirrer fixed, the resistance of the putty arrests the drum. The chamber may rotate to pivot the pawl. In an alternative construction, the chamber is outside of and at one end of the drum and is rotated on a spigot by a worm on the drum end engaging a worm-wheel on the chamber. When the strap jerks, a trigger keyed to the stirrer shaft rotates releasing a pawl which arrests the drum.

Title: Sausage canner
Inventor: LONG MARSHALL
IPC: B65B19/34
Filed: 1958-08-14
Abstract: 869,517. Packaging-machines. MARLEN QUIPMENT CO. Aug. 4, 1958, No. 26116/58. Class 94(1). [Also in Group XXX] A machine for continuously filling cans with bundles of sausages comprises an endless conveyer having a series of holders into which ropes of sausages are placed extending along the conveyer length, the ropes being then severed between the holders and the holders rotated to enable the severed bundles to be ejected into the cans. The sausage conveyer comprises chains which pass over sprockets 22, 24 and carry groups of holders 44, each holder being of C-section and open-ended, and being pivoted on the chains. Ropes of sausages supplied in trays 87 on roller conveyers 86 are laid manually in groups of holders having their axes in the direction of travel of the conveyer. Bars 102 carried on a conveyer 94 engage the ropes through notches 106 to hold them in position while a helical knife 88 severs them between the holders. As the holders commence to turn about the sprocket 24, a member 68 engages lugs 50 on their pivots to turn them through 90 degrees, a plate 122 preventing displacement of their contents. Cans 78 pass down a guide 84 to a spider wheel 80 which aligns them with the rotated holders 44. A cam 142, Fig. 3, engages their closed ends so that they are forced successively over 'the adjacent protruding ends of the sausages. Ejector plungers 58 rotating with the sprocket 24 and reciprocated by a cam track 130 push the sausages into the cans, the filled cans passing down a shoot 138. The holders are rotated back to their original position by a projection 148 and an opposed roller, Fig. 9 (not shown), engaging a lug 46 on their pivots, and may pass between similar members as they are leaving the sprocket 22 to ensure alignment during filling. Any cut-off ends of the sausage ropes are ejected by a cam controlled air jet 162, Fig. 1, into a shoot, Fig. 4 (not shown).

Abstract: 1,107,377. Friction gearing. KLINGER MANUFACTURING CO. Ltd. 23 June, 1965 [25 June, 1964], No. 26273/64. Heading F2Q. [Also in Division D1] A false-twist spindle 2 is magnetically urged into frictional engagement with a driving wheel 9, an adjustable guard 24 (see Fig. 1, not shown) being positioned so that under abnormal conditions such as a sudden increase in tension in the yarn passing through the spindle or a knot or other irregularity in the yarn causing the spindle to move out of frictional engagement with the driving wheel, the guard arrests movement of the spindle while it is still within the effective zone of the magnetic field. Thus when the abnormal condition ceases the spindle is returned to its normal running position by the magnetic field. The guard 24 is of non- magnetic material and is pivoted at 23 to a stationary cover 21, being secured in operative position by a releasable spring clip 25 and adjusted by a screw 27. The spindle is made of magnetic material and is urged against the driving wheel 9 by horseshoe magnets 13, 14 having their adjacent poles alike and joined by pole pieces 17, 18 having flats 17a, 18a close to the ends of the spindle. The spindle has a central ridge 19 positioned in a groove between friction bands 10, 11 on the driving wheel to limit axial movement of the spindle. In a modification (Fig. 6) the spindle is formed with flanges 34, 35 co-operating with the outer edges of the bands 10, 11 or a single driving band to limit axial movement. In either case the guard is so positioned that should the spindle tilt direct contact between the spindle and the pole piece flats 17a, 18a is prevented. The guard may be formed with a pad 31 of material of low coefficient of friction having a groove 32 accommodating the spindle.
