Abstract: 1,000,160. Variable resistors. PAINTON & CO. Ltd. Nov. 25, 1963 [Dec. 5, 1962], No. 46001/62. Heading H1S. [Also in Division B3] An electrical or electronic component has a casing made of plastics material with one or more elements of a heat or heat and pressure, deformable thermoplastics material projecting from one face of the casing. The projecting elements serve to mount the component on or space the component from, a support. When used for mounting, the elements extend through holes in the support and enlarged heads formed on the elements by the shaped bit of a soldering iron retain the elements in the holes. As particularly described, the component is a miniature potentiometer and comprises a casing 1 having a base 2 and lid 3 formed of thermoplastics material, e.g. Delrin or Zytol. A recess 4 in the base receives a resistance element 5 engaged by end clips 6 whilst a recess 9 receives a lead screw 10 projecting through a casing hole 11 and having a slotted adjusting head 12. A spring contact wiper 13 having a dimple 14 engaging the lead screw 10 has an arm 15 engaging the element 5 and an arm 16 engaging a metal strip 17. The clips 6 have wiring tags 7 extending through slots 8 and the strip 17 has a wiring tag 18 extending through a slot 20. Five projecting stud-like elements 21 are formed integrally with the base 2 and as shown in Fig. 3 three of them extend through holes 26 in a mounting bracket 24: The heads of the elements 21 are given a mushroom shape by applying the bit 28 of a soldering iron, Fig. 4c, this figure showing the bit removed after the deforming operation. In a modified arrangement, Fig. 5, for mounting the potentiometer on a printed circuit panel 31 the studs 21 merely act as spacers and the wiring tags 7, 18 extend through holes 30 and are soldered at 33 to the printed circuit tracks. Various alternative brackets attached to the potentiometer as in Figs. 1-4 are described with reference to Figs. 6-11 (not shown).

The plate 2 carries a spring-blade 8 having ends 8a, 8b and is for mounting on a relatively movable part such as a casement 4 or a fixed frame 5. The bolt 1 is apertured at 10a and 10b, is stepped at 14, 16, 19 and 21 and is provided with an extension 1a for engagement with a portion 3 of a plate 6 which is mounted on the other relatively movable part. The bolt 1 is in the bolting position in Fig. 8, the extension 1a of the bolt being in engagement with the portion 3 of the plate 6, the end 8a of the spring 8 abutting the step 16 of the bolt and the end 8b abutting the step 19. Release of the bolt is effected by a key 20 being inserted through the aperture 10a in the bolt. Thus the latter can be moved to the position shown in Fig. 9 where the portion 1a has disengaged the portion 3, the end 8a of the spring 8 engages the step 21 and the end 8b engages the step 14. Release of the bolt is by the key being inserted through the aperture 10b.

Abstract: 1293390 Testing plastics articles for leaks OWENS-ILLINOIS Inc 22 Oct 1969 [23 Oct 1968] 46569/69 Heading G1S An apparatus for leak testing a hollow plastics article B comprises means for supporting the article, means for moving the article to engage a nozzle 52 on a cylinder 51 and to continue the movement to move the cylinder relative to a stationary piston 61 to force fluid from the cylinder into the article, and means for sensing any loss of pressure within the article (71), Fig. 6 (not shown). Bottle B is grasped by jaws 45 actuated by cam surfaces 35, 36, 37 when platform 25 is lifted, and the bottle is lifted to engage nozzle 52 and seal 53. Springs 30 keep platform 26 stationary until platform 25 is engaged by heads 33 of pins 32 attached to platform 26.

Abstract: A scintillator for a  particles is prepared by depositing by evaporation successive layers of a translucent plastic, and including in the liquid applied to form one layer a fluorescent inorganic powder; the scintillator has a total thickness of about 10 m .  The scintillator may comprise, e.g. five layers of nitrocellulose, the top one containing the phosphor powder, and may also have alternate layers of a metal, e.g. aluminium, and plastic, e.g. alternately polyvinylalcohol (water soluable) and polyvinylformol chloroform soluable).

Abstract: 1,079,155. Pneumatic separators. P. I. DINESS. Nov. 23, 1964 [Nov. 29, 1963], No. 47608/64. Heading B2H. An air separator for cleaning grain comprises an upright container 1 in which an upward current of air is established by means of a fan 2 and into which the grain is fed through a pipe 6 directly on to a disc 5 which extends towards, but is spaced from, the wall of the container and which is provided with a number of radial slits extending from the periphery inwards. The segments 10 between the slits are twisted off the median plane of the disc to form oblique guide vanes. The disc may be stationary or may be rotated by the upward air current impinging on the vanes. The grain falling from the pipe 6 is thrown upwardly and obliquely by the vanes when the disc rotates, and the air passing through the slits keeps the material in suspension above the disc. The light impurities are carried by the air current and discharged through a tangential outlet 3 while the clean grain falls down through the slits or by-passes the disc and is collected in a hopper 8. When the disc is stationary, the upward air current is given a whirling movement by the vanes. The disc may be by a high rate of grain supply to rotate in the direction opposite to that in which it rotates when acted upon by the air.

Abstract: 1,110,297. Vacuum switches. GENERAL ELECTRIC CO. 11 Nov., 1965 [16 Nov., 1964], No. 47869/65. Heading H1N. To limit the arc voltage, a vacuum switch has a pair of electrodes 17, 18 shaped to provide plurality of gaps 30 in which parallel connected arcs 32 ... 35 form. The arcs extend in directions generally parallel to the magnetic field 45 resulting from the current flowing through the switch, and the adjacent arcs produce magnetic fields which are substantially self-cancelling so that the magnetic field component acting perpendicularly to any arc is small. In the arrangement shown the upper electrode 17 is fixed and has two extensions 26 which are interposed between similar extensions 26a from the lower electrode 18 which is movable rectilinearly along its axis. The electrodes are of copper and the electrode 18 has tips 42 of copper-bismuth alloy which co-operate with a face 43 of the electrode 17. The tips 42 and face 43 constitute the separable contacts of the switch at which the arcs are initially drawn. Each electrode may have more than two extensions, Fig. 8 (not shown), and the lower electrode may be pivoted so that contact is directly made and broken between some of the extensions 26, 26a, Fig. 7 (not shown). In a further arrangement, Figs. 9 and 10 (not shown), both electrodes are fixed and a pair of co-operating contacts is disposed in the central space between the electrode extensions 26, 26a.

The antibiotic tylosin is produced in increased yield by the fermentation of Streptomyces fradiae NRRL 2702 or NRRL 2703 in a nutrient medium containing, as additive, 25 mcg./ml. to 1500 mcg./ml. of a crude tylosine hydrolyzate, desmycosin, O-mycaminosyl tylonolide, dihydrodesmycosin, dihydro - O - mycaminosyl tylonolide, mycarose, mycinose or mycaminose. The crude tylosin hydrolyzate may be produced by heating an aqueous solution of tylosin, or a salt thereof, at pH 2À0, washing the resulting mixture with an immiscible organic solvent, and concentrating the aqueous phase to dryness. It is preferred to add 100 to 200 mcg./ml. of the additive, and to make the addition up to 48 hours after the initiation of the fermentation. Tylosin is recovered from the fermentation broth in a conventional manner.
