Title: Improvements in or relating to circlip dispensers
Inventor: GLENDENNING ROBERT WALTER
IPC: B65G59/06
Filed: 1962-07-14
Abstract: 979,982. Circlips. ANDERTON SPRINGS Ltd. July 12, 1963 [July 14, 1962], No. 22880/62. Heading F2H. [Also in Division B8] Circlips are stacked on rod 27 and are discharged one by one from the bottom thereof by a hand tool (not shown) and the discharge is assisted by arm 17 pivoted at 18 and by studs 42 and 43. Arm 17 is provided with two tongues 22 and 21 which in turn feed the bottommost circlip forward to the right in Fig. 1, and studs 43 and 42 are carried by plates 39 and 38 pivoted at 41 and 40 and resiliently influenced by spring 44 to permit the separation of the studs 43 and 42. Studs 43 and 42 serve to position the lowermost circlip. Additional circlips may be fed to rod 27 by rod 50 which is secured to rod 27 at 52 by clamp 53. Operation.-At the bottom of rod 27 two circlips are positioned separated from and clear of the rod, viz. a rear circlip resting on the top surface 30 of fixed plate 11, and a forward circlip resting on the top surface 31 of fixed plate 14 and being positioned between studs 43 and 42. The operator inserts his hand tool into the holes 8 (Fig. 7) of the forward circlip and pulls it outwards past studs 43 and 42, the studs yielding to allow the discharge of the circlip by the passage of the circlip between them. This forward movement of the circlip causes by engagement with tongue 21, the forward pivoting movement of arm 17 about its pivot 18. And this forward movement of arm 17 causes, by engagement of tongue 22, the advancement of the rear circlip to the position vacated by the forward circlip. In this way the forward circlip is now positioned sufficiently clear of the rod 27 to be ready for engagement by the hand tool when the next discharge is required.

Title: Hydrohalide salts of oxytetracycline
IPC: A61K31/65
Filed: 1956-07-30
Abstract: An hydrohalide salt of oxytetracycline is obtained by dissolving up to about 0.3 g./ml. amphoteric oxytetracycline in an aliphatic alcohol of up to six carbon atoms in the presence of a solubilizing agent consisting of (a) 0.01 to 0.05 g./ml. of a hydrogen halide, (b) 0.02 to 0.3 g./ml. of a soluble alkali metal halide, (c) 0.02 to 0.3 g./ml. of a soluble alkaline earth metal halide other than calcium chloride, or (d) 0.02 to 0.3 g./ml. of a soluble zinc halide, and subsequently treating said solution with 0.02 to 0.06 g./ml. of a hydrogen halide thereby precipitating said oxytetracycline hydrohalide salt.  The metal halide should be soluble in the particular solvent selected to the extent of at least 0.02 g./ml. at ordinary temperatures.  Useful combinations are calcium bromide in methanol or ethanol, strontium chloride in methanol, magnesium chloride in methanol, sodium bromide in methanol, zinc chloride in methanol and lithium chloride in methanol.  Suitable hydrogen halides are anhydrous hydrogen chloride, concentrated hydrochloric acid and concentrated hydrobromic acid.  Amphoteric oxytetracycline may be produced in situ by treating a suspension of crude oxytetracycline hydrohalide with an organic amino in the aliphatic alcohol.  The suspension of oxytetracycline so produced is then treated with an alcohol solution of the metal halide, filtered and the hydrohalide salt precipitated by the addition of the appropriate acid.  Suitable amines are pyridine, piperidine, triethylamine, trimethylamine and ethanolamine.  Specification 684,417 is referred to.

Abstract: 786,227. Screwing-up and unscrewing nuts and bolts. ARO EQUIPMENT CORPORATION. Aug. 15, 1955, No. 23479/55. Class 83(3). A power-operated ratchet-wrench comprises a C-shaped head with jaws to receive the small diameter of the nut, inwardly of which a partial cylindrical surface is provided of a size to receive the corners of the nut, roller-means for engaging the corners, spring-means biasing the roller-means so that when the head is rotated in one direction the nut is engaged and when reversed the roller-means move over the nut, and power-operated means for oscillating the head in a supporting-frame. A pneumaticmotor 10, Fig. 1, controlled by a valve 12, forms a handle for the wrench and is secured to a frame 18 which is flat at its forward-end, Fig. 3. The motor-spindle 16, Fig. 1, drives a cam 38 which reciprocates a spring-returned rack 26. The rack engages a pinion 24 which in turn oscillates, through gear-teeth 36, a C-shaped head 28. The latter is carried in an arcuate guideway of the frame and is adapted to fit over the small diameter of a hexagon nut or bolt. A pair of spring-biased rollers 60, 62, Fig. 4, engage the corners of the nut and rotate it through 30 degrees at each clockwise oscillation of the head. A spring-controlled latch 78 prevents the nut from turning back when the head reverses. An alternative form of ratchet-grip comprises four rotatable dogs 160, 160a, 161, 161a, Fig. 10, which grip in pairs, and a serratedmember 169 which engages the nut-corners to prevent undesired reverse rotation.

Abstract: 1,117,302. Conveyers. FORDS (FINSBURY) Ltd. 6 Sept., 1965 [5 June, 1964], No. 23502/64. Heading B8A. An automatic device for stopping or diverting the feed of articles 2 on a conveyer 3 between machines 1 and 4, comprises a device 6 for detecting the movement of articles on the conveyer and for controlling a timing device 7 which after it has operated for a pre-set time period either stops the upstream machine 1 or diverts the articles coming therefrom, the detecting device 6 causing the timing device 7 to be switched off before it has operated for the set time period, except when the device 6 detects a queue of articles which is stationary and/or exceeds a predetermined length. The detector device 6 comprises an arm pivoted at 18 to swing into the path of the containers under spring bias. A magnet 8 on the arm, actuates a reed switch in the timing device 7, when the arm is deflected by an engaging article 2, and initiates the timing mechanism. The latter is switched off as the magnet 8 is moved away from the reed switch as the container passes the arm of device 6. The magnet 8 on the arm may be replaced by a plate which shields the reed switch from a fixed magnet when the arm is deflected. In a further embodiment, a second detection device is provided to operate a second timing device reed switch in series with first said switch, when a row of contacting articles is desired to be moved along the conveyer the timing device running its full time period to stop the upstream machine 1, only when the row is stationary.

Abstract: 696,046. Generating combustion products under pressure. WILLIAMS, F. D. M., and MORRISON, D. E. Oct. 15, 1951 [Oct. 17, 1950], No. 23973/51. Class 51(i) In a combustion chamber, for a gas turbine engine for example, in which the flame tube comprises sections which are spaced apart where they adjoin to form inlet passages for cooling and insulating air, the sections are spaced apart by means of spacers which are secured to at least one of the sections in a recess in that section, the depth of the recess being at least equal to the thickness of the material of the spacer. In Fig. 2, the spacer 16 is formed in the section 12 by cutting a circumferentially-directed slot 17 and pressing the material between the slot and the edge 18 of the section outwardly. A recess is formed in the adjacent section 13 by pressing the material outwardly as at 19 and the spacer is secured in the recess by welding or other means at 20, the circumferentiallydisposed portion of the spacer thereby causing no obstruction to the flow of air A through the passage 15. In Fig. 3, the spacers 16 are not formed at the extreme edge of the section 12, and the recess is formed by pressing the edge of the adjacent section 13 outwardly by the joggle 22, the circumferentially-directed portions of the spacers being accommodated in the recess and secured thereto. In a third embodiment, the recess is formed by means of a doubler plate secured around the section 13 with a portion overlapping the section 12. The spacers may be formed on the overlapping section 13 in which case the recesses would be inwardly disposed in the section 12. The invention is applicable to both tubular and annular type combustion chambers. Specification 687,964 is referred to.
