Title: Improvements relating to grinding or abrading machines
IPC: B24B5/18
Filed: 1928-02-25
Abstract: 305,839. Hughes, V. A. B., (Cincinnati Grinders, Inc.). Feb. 25, 1928. Centreless grinding; guides and rests. - In a machine for cleaning up or finishing thin hollow or solid bodies of substantially cylindrical shape but which are slightly conical or non-circular, the work is freely supported in contact with a grinding wheel so as to be capable of angular and lateral movement. The machine comprises a grinding wheel 12 rotated at high speed by a belt 13 and a regulating wheel 15 rotated at a low speed by a belt 74, gearing 80, 81, and a flexible shaft 72, 16. The bearings for the regulating wheel are carried on a frame 18 pivotally supported by a shaft 19 on a base 21 which may oscillate freely about a trunnion 31 on a slide 30 movable to and from the grinding wheel by a hand wheel 37. The base 21 is provided with rollers 32 to assist the freedom of oscillation about the trunnion 31 and the frame is supported at the rear by plungers 45 urged by springs 51 against studs 47 on the base, the pressure of the springs being adjustable by nuts 49, 50. The regulating wheel 15 is moved to and from its operative position by a pedal 60 and a link 25 attached to the frame 18. In operation, when the regulating wheel has been withdrawn by the pedal, the work W is placed upon a roller 40 rotatable on a bracket 43 attached to the slide 30 and is kept in position by a fixed blade 65 on the base. The regulating wheel is then allowed to come in contact with the work and pressed it, by means oE the springs 51 and a weight 22, against the grinding wheel in such a manner that the latter is able to grind it uniformly all over without removing an undue amount of material at any point. The work may subsequently be preserved by lacquering &c. Grinding fluid is supplied to the work by a pump 78.

Title: Process and apparatus for the production of reinforcement for conc rete
IPC: E04C5/06
Filed: 1972-02-09
Abstract: 1370986 Making lattice girders; angular bending; welding by pressure IMEX AG 9 Feb 1972 [18 Feb 1971] 6044/72 Headings B3A B3E and B3R [Also in Division E1] A reinforcement is made from a mat having transverse bars 3, 4, Fig. 1, and longitudinal bars 2, by simultaneously bending and flexing the bars 3, 4 in a direction obliquely to the plane of the mat towards one side of the plane to form a row of pyramids 10, Fig. 3, and interconnecting the apices 11 of the pyramids with a bar 12. The mat is placed on pivoted plates 16, Fig. 5, so that a row 5 of meshes having a greater width than normal is over the gap 17, after which arms 20 are pivoted to grip the bars 3, 4 between the arm ends and the plates 16. Two rows of inclined punches 22, 23 are then moved upwardly so that their studs engage the bars 3, 4 of the row 5 and simultaneously bend and flex the bars 3, 4 to form the row of pyramids 10. In consequence of the bending of the bars, the width of mesh row 5 decreases to the width of a normal row. The benders are then retracted and a slide 54 is advanced to position a bar12 under top welding heads 44. Bottom welding heads 45 are then moved to engage the underside of the pyramids 10 and move the pyramid apices 11 upwardly to lift the bar 12 off the slide 54 into grooves 50 of the head 44. Finally the bar 12 is welded to the apices of the pyramids after which the welding heads 45 are retracted and the plates 16 swing upwards by a small angular amount to compensate for flexural stresses.

Title: Improvements in or relating to bucket conveyors
Inventor: TAYLOR RICHARD ARTHUR
IPC: B65G17/12
Filed: 1951-03-09
Abstract: 723,305. Endless conveyers. BABCOCK & WILCOX, Ltd. March 9, 1951 (March 10, 1950], No. 6074/50. Class 78 (1). Each pivotally - suspended bucket of an endless bucket conveyer comprises a cam and a roller mounted adjacent the cam for engaging a complementary track arranged to turn the bucket, the arrangement being such that the cam impinges on the track at a small angle and rolls along it during initial turning of the bucket and that a surface of the track is thereafter engaged by the roller during further turning of the bucket. The buckets 1 are provided at each side with a cam member 49, the upper part o f which is provided with a bearing for pivotally mounting the bucket between a pair of endless chains, while the lower part is provided with a cam surface 64. A roller 65 is rotatably mounted on a pin 99 inserted in the cam member and held in place by a plate 101 engaging a slot in the pin and bolted to the cam member. As the buckets approach the discharge point each cam surface 64 engages by its forward portion LM with the initial part 107 of a track at a small angle thereto. This effects a small turning of the bucket followed by roller 65 engaging a steeply rising part 108 of the track which causes the bucket to pivot about the axis of the roller into its dumping position. A horizontal part 109 of the track follows the part 108 and roller 65 rides up the part 108 on to this part 109 to complete the turning into dumping position. A part 110 of the track guides the roller 65 to return the bucket slowly. At point C the forward portion LM of the cam surface 64 re-engages the track which becomes gradually less inclined and after the point D the rear portion KL of the cam surface 64 is engaging the final portion of the track. If the bucket is swinging as it approaches the discharge point the rear portion KL of the cam surface 64 may engage the initial part 107 of the track, still at a small angle, instead of the portion LM. Specification 723,304 is referred to.

Title: Improvements in or relating to warp stop motions for looms for weaving
IPC: D03D51/20
Filed: 1929-02-25
Abstract: 329,053. Wood, A. E., (Crompton & Knowles Loom Works). Feb. 25, 1929. Stop-motions, warp.-Relates to devices of the kind in which, upon warp breakage, a narrower part of a slot in a drop wire prevents the oscillation of a non-circular vibrator rod. The vibrator rods 25 have depending arms 27 linked together and to a control rod 31 adapted to move a rod 33 on a cam-worked lever 36 beneath a shoulder 34 or an adjustable abutment on the shipper handle 11. One of the vibrator rods has an arm 40 carrying a tubular part 42 in which a cam-worked rod 43 having a stop 44 moves. Normally, the part 42 moves downwardly with the actuator rod 43 and causes the rod 31 to be moved from under the shoulder 34, but when a warp breaks, the fallen wire causes the sleeve 42 to be held in raised position as shown in Fig. 5, thereby causing the end of the rod 33 to be retained under the shoulder 34 while it is raised by the lever 36. The handle 11 is thereby turned to stop the loom. A pivoted guard plate 70 prevents axial displacement of the arms 27 and of their bushings.

Abstract: 747,049. Fluid pressure brakes. BENDIXWESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. March 3, 1954 [April 3, 1953], No. 6265/54. Class 103 (1). [Also in Group XXIX] A compressed air braking system for vehicles comprising a compressor 10, reservoir 12, governor 28, master control valve 14 and front and rear brake actuators 16, 18 respectively has a quick-release valve 30 between the master valve 14 and the front brake actuators. The valve 30 has a rubber &c. closure member 46 normally held by a spring 48 away from an exhaust port 36 so as to vent the connections 38, 40 leading to the front brakes. A spring abutment 50 has a corrugated flange 68 in engagement with the closure member 46 whereby pressure applied by the master valve to the inlet 34 of the quick release valve deflects the material of the closure member 46 into the corrugations so that air under pressure may pass to the brakes, the exhaust port 36 having been closed by deflection of the central part of the closure member. Further increase of inlet pressure moves the remaining part of the closure member away from its seat 54, compressing the spring.

Patent GB-491320-A (GB)
Title: Improvements in the recovery of phenols from oils
IPC: C07C37/00
Filed: 1937-03-04
Abstract: Phenols are recovered from oils which have been subjected to hydrogenation or prepared under hydrogenating conditions by extracting with salt solutions having an alkaline reaction, treating the salt solution with weak gaseous acid, separating the phenols from the solutions and heating the latter to free them for further use from the gaseous acid.  Suitable salts are the alkaline or alkaline earth metal salts of weak inorganic acids such as boric, vanadic, silicic, or phosphoric acid, or of hydrogen sulphide, or of weak organic acids such as alanine, glycocoll or their alkyl derivatives such as methylalanine, dimethylalanine, hydroxyethylalanine, ethylenediaminoacetic acid, or triethylenetetramino acetic acid. Suitable weak gaseous acids are carbon dioxide, or hydrogen sulphide. The extraction and acidification steps may be carried out at raised temperature, e.g. 50-60 DEG  C. and heating of the solution may be at 120-150 DEG  C. under pressure.  Phenols remaining in the salt solution after acidification may be extracted with liquid hydrocarbons, or with ether.  A preliminary treatment with ammonia, milk of lime, soda or potash may be employed to remove aromatic hydroxy acids which may be present in the oil.  Suitable oils are obtained by hydrogenating the products of high or low temperature coking or extraction of coal or peat; or during the preparation of oils by methods involving hydrogenation.  In examples: (1) phenol is extracted from a mineral oil obtained by destructive hydrogenation with an aqueous solution of the sodium salt of glycocoll.  Carbon dioxide frees the phenol from the aqueous solution which after separation and heating to expel the carbon dioxide is ready for re-use; (2) sodium sulphide is used as extracting agent for a hydrogenated brown coal low temperature carbonization tar.  Hydrogen sulphide is used as the gaseous acid; (3) an extract from mineral coals, treated with hydrogen at 450 DEG  C. under pressure is extracted with calcium sulphide liquor which is then treated with hydrogen sulphide to release the phenols. The separated liquor is heated to remove hydrogen sulphide and the extracted oil which still contains some phenol is again treated with the revived liquor. Specification 338,638, [Class 2 (iii)], is referred to.
