Title: A device for turning inside out collars, cuffs of shirts and similar articles
IPC: D06G3/02
Filed: 1957-03-01
Abstract: 855,383. Turning articles inside-out. ETON A. B. March 1, 1957 [March 2, 1956], No. 6899/57 Class 112 A device for turning inside out articles comprising at least two pieces of fabric interconnected along their edges has a stand arm 16 mounted on a shaft 15 so as to be rotatable thereon from an upper position to a lower position less than 180 degrees from the upper position, the arm carrying at its free end a tweezer-like implement 19 which extends towards the extended axis of the shaft 15, the tweezers being turned approximately half a revolution about their longitudinal axis as the stand arm moves from its upper position, when the ends of the tweezers are pressed apart, to its lower position, when the ends are pressed together. The article to be turned is placed over the point of a mandrel 66 with its right surfaces facing each other and one each side of the mandrel. The mandrel is slidably carried in the base 14 of the device. The depression of a treadle rod 62 operates a lever 60 to raise the mandrel towards the points 21 of the tweezers. Contacts 100 are closed by the striker 102 to energise a lower solenoid 98 which rotates the gears 93, 92 by the pull rod 95 to cause the stand arm 16 to move from its upper to its lower position. As it moves away from the upper position a saddle 43 is disengaged from an abutment 49 on the shaft and operates a three armed lever 39 to close, by means of a rod 37 and associated linkage, the tweezer points and so grip the corner of the article. Stops carried on a collar 82 rotate rods 70, 72 as the arm swings downwards, to rotate a bevel quadrant 69. A bevel wheel 68, in mesh with the quadrant and fast with the tweezer body, rotates the implement through approximately 180 degrees about its own axis. When the arm reaches its lower position (shown in full lines in Fig. 2) the operator lifts that piece of fabric not lying between the mandrel and the tweezers over the latter to turn the article inside out, the twisting motion of the tweezers having ensured a sharp point to the corner of the article. Release of the treadle withdraws the mandrel, and opens the tweezer points by means of the link 56 and a bell crank lever 53 contacts 101 being then closed to energise the upper solenoid 97 to rotate the gears and return the arm 16 to its upper position. A detent in the member 84 engages the collar 82 during the return movement of the arm to reposition it so that during a subsequent operation the tweezer-like implement rotates through 180 degrees in the opposite direction to that previously described. The device may be operated pnuematically instead of electrically. The Specification also describes, but does not claim, a pair of hand operated tweezers by which the same method of turning inside out can be accomplished by hand.

Title: Improvements relating to photographic camera shutters
IPC: G03B9/20
Filed: 1946-03-06
Abstract: 613,537. Photographic shutters. KODAK, Ltd. March 6, 1946, No. 6997. Convention date, Jan. 5, 1945. [Class 98 (i)] A photographic camera shutter having blades operated by one or more blade rings incorporates an auxiliary device for opening the shutter for focusing without disturbing the normal release means or exposure setting, said device comprising a pivoted driving member carrying a projection engageable with a recess in a blade ring to move it so as to open the blades. As shown, the shutter itself, of the between-lens setting type, is identical with that of Specification 613,531. On the mechanism base-plate 15 are concentric annular slideways for a pair of blade rings 18, 19, linked by pin-and-slot connections 25, 26 and 27, 28 to an arm 23 pivoted on the base-plate at 24 so that the rings always rotate in opposite directions to open and close double-ended symmetrical shutter blades 3 which are pivoted at 20 on the blade ring 18 and have pin-and-slot connections 21, 22 with the blade ring 19. The shutter is set by moving the operating slide 37 clockwise, when nose 40 engages an arm 30 on the blade ring 19 which in turn engages a pin 31<1> on the master member 31, pivoted at 32 on an arm 33, itself pivotally mounted on the plate 15 at 34 and spring-urged anticlockwise against a stop (not shown), the master member being rotated against a spring 44 to a position where the right-hand end 41 of a lever 57, pivoted on the base-plate at 58, snaps behind a lug 42 on the master member to hold it set. As a result of the setting movement, the tail 50 of a lever 48, pivoted at 49 and spring-urged anticlockwise, moves into engagement with a tooth 53 of the ratchet-wheel 51. The shutter is released by moving the slide 37, which after each actuation is returned to its rest position by springs 137, in an anticlockwise direction when a lug 471 engages arm 47 of the lever 48 to disengage the tail 50 from the ratchet 51 which then rotates clockwise to trip the latch 41 and release the master member to drive the blade rings. The device for opening the shutter for focusing is operable by a knob 10 (Fig. 7, not shown), and consists of a member 62, having a tooth 63 adapted to engage a notch 64 and tooth 65 on the blade ring 18 and also an abutment 63<1>. To operate the device, the shutter must first be set when notch 64 is brought opposite the tooth 63 which together with the abutment rides on the blade ring when the shutter has been released. The usual preexposure adjustments of shutter speed, diaphragm aperture may be made and the knob 10 then rotated anticlockwise against spring action, until the abutment 63<1> engages the ring 18, to open the shutter which may be held open by a " pimple and dimple " latch between the knob and the shutter casing. After focusing this latch is disengaged and the knob 10 returned to its rest position when the shutter is again in the set position ready for anticlockwise movement of the slide 37 to make an exposure.

Title: Fuel converting method and apparatus
IPC: F02M27/00
Filed: 1975-02-20
Abstract: 1491138 Treating I C engine charges NISSAN MOTOR CO Ltd 20 Feb 1975 [26 Feb 1974] 7135/75 Heading F1B [Also in Division C5] A method of converting a fuel into a freehydrogen containing gas comprises the steps of filling a first space with a base mixture of fuel, oxidant and water having a predetermined ratio to each other, compressing the base mixture, providing a second space communicating with said first space, filling separately the second space with a combustible mixture of fuel and oxidant having a predetermined ratio to each other igniting the combustible mixture and directing a jet of flame into the compressed base mixture thus causing rapid conversion of the compressed base mixture into a free-hydrogen containing gas by the flame making the gas perform work during the expansion and accumulating the work performed as power for compressing the base mixture. An apparatus for carrying out the method comprises a piston 18 reciprocable in a cylinder 16 and connected by rod 32 to crank-shaft 30, which carries a flywheel. During the intake stroke of a four-stroke cycle, valve 34 is open and fuel, air and water are drawn through chamber 38 to form the base mixture. Simultaneously, valve 62 is open and fuel and air are drawn through chamber 56 to form the combustible mixture in auxiliary combustion chamber 50, which is provided with spark-plug 68. On the next stroke of piston 18, both mixtures are compressed, the combustible mixture is ignited and a jet of flame from port 24 initiates the reaction in combustion space 28 which results in the formation of free-hydrogen containing gas. The reaction products expand in driving piston 18 down on its third stroke. During the fourth stroke, valve 36 is open and the free-hydrogen containing gas passes through conduit 72 to chamber 70 where fuel is added and hence by duct 74 to I.C. engine 12. In a modification, Fig. 2 (not shown), a hydrogen peroxide reservoir (82) is provided and is connected to a catalytic decomposer which produces oxygen and high temperature steam. The oxygen is fed to mixing chamber 56 in place of the air supply and the steam is condensed and provides the water supply to the mixing chamber 38.
