The donte 15 is joined to the ribbed collar 23 by bolts 22 and a bolt (not shown) secured to the drawbar 17. The holes 11 are between 1/16 inch and 1/8 inch diameter flared on the inside of the skirt. The skirt 10 has longitudinal -recesses 35 of a size sufficient to provide the same thickness of lining over internal locking bars.

Abstract: 814,196. Milling; programming for machine tools. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 5, 1955 [Sept. 16, 1954], No. 26833/54. Class 83 (3). [Also in Group XXXVIII] Apparatus for accurately locating a tool relative to a workpiece comprises a rod extension to the tool-holder associated with a follow-up switch, whereby misalignment closes an energization circuit for a servomotor to reposition the tool. A multiple tool-holder comprises a turret 2, Fig. 1, carrying three chucks 15, 16, 17, the former carrying a tool 34 which is to be positioned relative to work secured to a table 1. An extension 18 of the tool is engaged by spring- loaded feeler arms 24, 25, Fig. 3, attached to micro-switches 28, 29, and 30, 31, so that displacement of the tool 34 and rod 18 in the X- direction closes one of the switches to cause a motor 7 to drive the turret 2 to the neutral position. The switches and feeler arms are carried in a casing 21 mounted on the main pillar 8. A further switch and feeler arrangement senses and adjusts displacements in the Y- direction. The follow-up switch may alternatively be replaced by strain-gauges, or a differential capacitor, or a differential photo-cell arrangement sensing deviation from the desired position. In one embodiment predetermined adjustment voltages are algebraically added to signals derived from a control record to accurately adjust the position of the tool. Specification 807,643, [Group XXXVIII], is referred to.

[Also in Group XXV] A web tensioning buckle comprises a crank arm 33, a ratchet wheel 42, intermittent rotation of which is effected by oscillation of the crank arm, web connection means 13 located at one end of the buckle and adapted to receive a web 11 and rotatable with the ratchet wheel to wind up the web when received on such means and means 20 at the other end of the buckle for coupling to a tension receiving member 10. The buckle comprises a frame 12 and the means 20 is a hook. The web connection means 13 consists of a pair of plates 28 arranged in parallel relation and between which the end of the web 11 is passed, the plates being carried by discs 31 (not shown) which rotatably fit into holes in the side arms 21 of the frame. The arm 33 is rotatable around discs 39 (not shown) carried by the plates 28. The arm 33 carries a pawl frame 36 by means of pivots 47a and the pawl frame at one end is provided with drive pawls 47 which engage the teeth of a pair of said ratchet wheels 42 which are carried by the plates 28. The arm 33 is lockable in a non-operative position by a releasble latch means 15. Reverse movement of the web connection means 13 is prevented by dogs 55 which are part of a plate 56 carried by the frame 12 and longitudinally movable in slots 25. The dog plate is loaded into engagement with the ratchet wheels by a spring 57. The pawls are biased into engagement with the ratchet wheels by a spring 53 trapped between the pawl frame and a bracket 50 carried by the arm 33. The latch means 15 comprises a spring biased latch 59 which is slidably mounted in the open end of the hook 20 and which snaps over the end of the arm 33. Manual retraction of the latch releases the arm. To enable the tension in the web to be released, projections 61 are provided on the arm which when the arm is moved beyond its normal range of movement engages the dogs 55 and releases these from the ratchet wheels ; when the pawls are released from the ratchet wheels by depression of the pawl plate the means 13 is released and can rotate in the opposite direction to relieve tension in the web.

Title: Inverter
IPC: H02M7/523
Filed: 1964-07-01
Abstract: 1,055,327. Inverters. JEFFERSON ELECTRIC CO. July 1, 1964 [July 12, 1963], No. 27246/64. Heading H2F. [Also in Division H3] In an inverter, oscillalations in an underdamped resonance circuit comprising capacitor 14 and centretapped primary winding 13 are maintained by appropriate switching of SCR 18. Upon triggering the SCR current flowing in the bottom half of winding 13 causes the capacitor to charge resonantly and, as it rises above twice the supply potential (2E), to cut off the SCR. The source of supply 2E is thus effectively removed and the capacitor resonantly discharges to below the zero level, whereupon the SCR is retriggered to recharge the capacitor to the 2E level. A pulsating current is thus produced in the winding 13 and the load which is shown as two fluorescent tubes. Feedback diode 26 limits the amount of reverse voltage able to be applied to the SCR and diode 28 limits the forward voltage. Pulses for triggering the SCR are provided by the conjunction transistor oscillator 25.

Abstract: Uranium ore is treated with sulphuric acid, and the resulting solution is neutralized in either one or two steps with calcium oxide, hydroxide, or carbonate to provide a precipitate comprising calcium uranate, calcium sulphate and hydroxides of such iron, aluminium, manganese, copper, and silicon as are present.  To this precipitate is added a reagent selected from sulphuric acid, <PICT:0928889/III/1> ferrous sulphate, hydrate, or ferric sulphate, in amount such as to ensure complete reaction of the uranium, aluminium, manganese and copper present, and the mixture is calcined at 100 DEG C.-400 DEG C., after which calcium nitrate solution, preferably in an amount sufficient to convert all the sulphates present into nitrates, is added to the calcined mixture, thereby obtaining a uranyl nitrate solution, which may be extracted with tributyl phosphate, if desired mixed with white spirits, from which the uranium may be reextracted with distilled water.  In the Figure, the starting precipitate is introduced together with sulphuric acid or ferric sulphate into mixer 1 and from there to drier 2 maintained at 100 DEG C.-400 DEG C.  The mixture is then reacted with calcium nitrate solution in tank 3, washed in drum washer 5, and extracted with tributyl phosphate in 6, if necessary after adding nitric acid at 7.  Uranyl nitrate is removed at 8, and the remaining mixture is mixed with calcium carbonate in tank 9.  Iron, aluminium, copper, and manganese values are removed at 10, and the calcium nitrate solution is recycled via line 11.

The needles 2 revolve past a brush 4 which receives a fat soluble ink from a reservoir 5, and as the drum 1 is moved over the meat product the needles penetrate into the fat, and a number of trade marks are printed therein, so that when the product is cut up into smaller joints, these will all be marked. A guard 16 is arranged beween the needles 2 and the handle 3. Inking-apparatus. - The brush 4 has bristles embedded in a rubber plate and enclosed in a tubular sheath 18. The reservoir 5 is supplied with ink from a tubular reservoir arranged inside the handle 3. A screw-plug 23 with a course thread fitted with a gasket 24 controls the flow of ink to the lower reservoir, and this plug is normally closed to prevent a too rapid flow. Printing-surfaces. - The helical plates 10 are attached to the rim of a drum skeleton by means of screws, and the sides of the drum are enclosed by discs 12 secured by screws 13. The needles 2 are tempered, but in welding these needles to the plates 10 a clamp is used having an oil bath in which the tips of the needles dip. The shanks of the needles are thus annealed during the welding process, but the tips remain hardened, thereby diminishing tendency of the needles to break during the marking, process.
