Title: Pneumatically threaded tape drive
IPC: G11B15/67
Filed: 1967-08-24
Abstract: A web transport channel for pneumatically transporting a flexible web includes a plurality of blowing-air jet means, formed through the channel in its base region, and angled with respect to the channel to create a moving force on any web in the channel, and vacuum port means formed along the channel to remove air from between any such web and the channel for transporting and stabilizing the web, wherein the channel is substantially U-shaped, consisting of a pair of side members connected by a cross member adapted to receive and guide a web along the length, the air jet means being disposed in the cross member of the channel, and the vacuum port means being disposed through at least one side member of the channel adjacent the cross member and adapted, in operation, to remove any excess air which builds up between any web in the channel and the cross member due to the action of the air jets. As shown in Fig. 1, the channel is formed by side members 110 and 112 and cross member 114 the side members each have a plurality of ports 118 communicating with a hollow chamber 116. The cross member 114 is formed with a plurality of spaced slots 120, angled with respect to the bottom surface of the cross member, and each connected to a chamber 122. The chambers 116 are connected to a vacuum source, and the chambers 122 are connected together, and to a positive pressure source. In Fig. 4, the channel is in the form of a reel 60 with pressure chamber 66 communicating by angular slots 70 with the exterior vacuum slots or grooves 74 are provided in the two flanges 62 and communicate with hub holes 72 connected externally to vacuum. A complete system is described consisting of a supply reel with magnetic tape, which may or may not be enclosed in a cartridge, a transport channel according to the invention leading to a head assembly, and a further, similar, transport channel leading from the head assembly to a take-up reel. The take-up reel may have an apertured hub and apertured flanges all connected to vacuum. The connection to vacuum may be shut off after the first few revolutions of the take-up reel. Alternatively the take-up reel in the system may be of the form shown in Fig. 4, in which ease this reel is held stationary at first. In the initial winding- on phase the free end of the tape is drawn towards the hub 64 by the vacuum at slots 74, and is thereafter directed around the circumference of the hub by the jets 70. When friction between turns prevents further feeding, the winding-on may be continued by rotating the reel.

Title: Guide control means for raschel knitting machine
IPC: D04B21/20
Filed: 1968-11-08
Abstract: In a two-bed warp machine for knitting tights or the like certain guide bars are shogged over adjacent needles of one bed during formation of the body portion and over needles on the opposite beds during formation of the leg portions. The control of these bars is shifted from one to the other of two sets of pattern chains in an auxiliary pattern mechanism. Guide bars 1, 2 and 11, 12 which supply yarn to front and rear needle beds respectively, and bars 3, 9 and 4, 10 which supply single ends of yarn to both beds at the ends of the blanks are controlled by main pattern mechanism A. The remaining bars 5-8 are controlled by auxiliary mechanism B which includes two sets of chains 51, 51a. The bars are moved by slides 42 mounted in a box 43, movable by a fluid cylinder and piston 56, 57. When a counter 65 has registered a predetermined number of courses, set by an operator (on scales 71, 72, Fig. 3 not shown), the box is shifted so that following rollers 50 follow the other set of chains. While 'body fabric is knit guide supply yarn to the front and rear needle bars 5, 6 and 7, 8 each carrying one control beds respectively. To knit two legs integral with the body, when the box is shifted, bars 5, 7 and 6, 8 supply yarn to opposite needles on the two beds to join the inside of the legs. Several strings of blanks, joined alternately waist to waist and toe to toe, are knit across the machine. The main and auxiliary pattern mechanisms, which may each include two sets of chains, may be at the same end of the machine. In a modification (Figs. 8-10 not shown) the bars are controlled by levers (94) pivoted on an axle (100) in a movable frame (104, 112- 115). The upper ends of the levers carry guides (97) which slide in a grooved upper frame member (98). The bank of levers is movable to follow either of two sets of chains (91, 91a).

Abstract: A vehicle propulsion means for accelerating an unpowered toy vehicle along a predetermined path of travel comprises mechanical gripping members adapted for engaging and disengaging the vehicle on opposite sides thereof with substantially equal force and means for moving said gripping members at substantially the same speed and acceleration. As may be seen from Fig. 3, a cocking lever 31 is manually pulled into the position shown against the force of a spring 65 and a toy vehicle (not shown) on the roadway 13 moves the trip wire 33 causing the two gripping members 25 and 27 to engage and grip with equal force opposite sides of the vehicle and immediately move in the direction of vehicle travel to thereby accelerate the vehicle along the roadway. The track is preferably banked at each end to prevent the toy vehicles leaving the track. In an alternative embodiment shown in Fig. 8 the vehicle propulsion means comprises counter-rotating resilient tyres 263 and 263' (driven by the motor 221 through engagement of its drive gear 223 with one of the drum gears 259). Additional peripheral gear driven drums may be arranged so that one additional parallel track section and two further track sections at a lower level and at an angle to the first pair of track sections together make up a double flyover (see Fig. 10, not shown).

Title: Sulfide precipitation method of separating uranium from group II and group III metal ions
IPC: C01G43/00
Filed: 1974-08-23
Abstract: Uranium is separated from analytical Group II and Group III metal ions in an aqueous liquor containing uranyl ions. The liquor is extracted with a non-interfering, water-immiscible, organic solvent containing a reagent which will react with the uranyl ions to form a complex soluble in the solvent. If the liquor is acidic, the solvent is washed with water. Then to the solvent is added an aqueous solution containing about 0.5 to 1.0 mole per liter of (NH4)2CO3 or NH4HCO3 ions and sufficient sulfide ions to precipitate the metal ions as sulfides. The solvent and the aqueous solution are separated and the sulfides filtered from the aqueous solution. The ammonium-uranyl-tricarbonate in the aqueous solution can then be precipitated by increasing the concentration of (NH4)2CO3 or NH4HCO3 ions to about 1.5 to 2.5 moles per liter. The precipitate is filtered and calcined to obtain U3O8 or UO2.
