In a superposed cylinder knitting machine, knitwork is tensioned by two longitudinally spaced rings of segments 24, 26 each carried on a push rod 19, 20 with a cam follower 29 and an abutment member, the cam followers 29 engaging a cam 32 which moves the segments against springs 22 which bias them to press the knitwork against a surface 7a and the abutment members 30, 31 engaging control members such respectively that all segments are operative, no segments are operative or only segments over an arc are operative. Surface 7a is provided on an insert 7 secured to the sinker guide ring of the lower needle cylinder 2. The upper needle cylinder 1 is mounted on a rotatable sleeve 8 to which is secured sleeve 17 with vertical guideways for rods 19, 20. Segments 24, 26 have elastic extensions 25, 27 and form two interrupted rings adjacent surface 7a. Upper and lower pins 31, 30 project inwardly from rods 19, 20 corresponding to the rods which operate or don't operate respectively during the knitting of a heel. A lifting ring 36 mounted on a pin 34 centrally slidable in body 17 has a rim 35 supporting a ring 37 which can lift pins 30. A sleeve 38, slidable on pin 34 has a lifting ring 39 and at its lower end a ring 40 which can lift pins 31. Rollers 41, 49 carried on levers 42, 50 can engage rings 39, 36. The second arm of lever 42 is connected to a Bowden cable 47 and lever 52 with a detent to engage a lever 50 is connected to Bowden cable 57. By pulling on cable 47, e.g. by means of a control drum, the mechanism can be lifted out of action. If cable 47 is released and cable 57 is pulled to disengage the detent 54, all rollers 29 engage cam 32, so that segments 24, 26 bear against surface 7a to grip and tension the fabric being knitted. If the device is only to operate over part of the circumference, cable 47 is pulled and cable 57 released so that the fabric is tensioned over the part being knitted. To return to normal knitting, cable 57 is released.

Abstract: 1,038,220. Ion microscopes. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE & G.S.F.-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Nov. 27, 1963 [Nov. 28, 1962], No. 46924/63. Heading H1D. An ion microscope for analysing the surface of a bombarded sample 1 comprises a source of ions 20, electron-optical means 21, 22 for accelerating the ions and focusing them into a beam and directing the beam on to the sample 1, means 23 for neutralizing ions before they reach sample 1, and means for extracting from the beam any ions that have not been neutralized, thus producing a beam of fast neutral atoms which bombard sample 1 and extract secondary ions from it. As shown, positive ions are used and are neutralized by passing them through an enclosure 23 filled with gas at a low pressure so that they tear off electrons from the gas atoms and are thus neutralized. Any ions which have not been neutralized in enclosure 23 are extracted from the beam by a deflector and an ion trap (Fig. 2, not shown) at the outlet from enclosure 23. The positive ions extracted from sample 1 are accelerated and focused by electronoptical system 24, 25, 26 to form an image of the surface of the sample being analysed. To neutralize local negative charges left on sample 1, positive ions from a source 33 arrive at sample 1 with a velocity whose component normal to the surface is substantially zero and thus form a local layer of positive ions moving parallel to the sample surface. Negative secondary ions may be used for producing the image.

Alternatively the film may be Si 3 N 4 , SiO 2 -PbO glass, or SiO 2 -Al 2 O 3  glass. An opening is etched and a film 33 of SnO 2  is formed on the surface by pyrolysis of (CH 3 ) 2 SnCl 2  or SnCl 4  in a solvent vaporized in air or oxygen, and Sb 2 O 3  may be admixed. A P type Si semi-conductor is usable if SnO 2  is deposited at higher temperature, or Ge or GaAs may be used. Electrodes 34, 35 are formed by vacuum deposition of Ni on the opposed surfaces and photoetching the superfluous parts, and substrate 31 may be attached to a gold plated stem over Au-Si with optional Sb eutectic. Electrodes may alternatively be Ag, Au, Cr or Al or a tripartite layer of Cu or Ag; Au, Ni or Al, and Ti on the SnO 2  film, Ni on Ti may also be used (Fig. 6). The substrate is divisible by scribing along VII-VII into composite chips (Fig. 7, not shown). The device may receive light through the thin SnO 2  layer and a connection may be attached to the electrode 34 overlying the layer and subjacent insulant.  In a modification (Figs. 8A, 8B) a N-type Si substrate is formed with a SiO 2  film with opening 402, into which is deposited a SnO 2  film 43 with Ni electrodes 44, 46; the superfluous SnO 2  being removed by depositing Zn over the portion to be removed, etching with dilute HCl, redepositing Zn, and etching with concentrated HCl, while unnecessary Ni is removed by etching with FeCl 3  through photomasking; the etching being repeated if necessary. The individual rectifier sections are divided up by scribing and breaking. For rectification, the SnO 2  films is obscured by a layer of electrode material or opaque resin (Fig. 9, not shown). The device may form part of an integrated circuit, e.g. with transistors.
