Title: Improvements in reel mounting apparatus
IPC: G11B15/66
Filed: 1969-10-13
Abstract: 1,219,070. Mounting tape reels on hubs. INTERNATIONAL BUSINESS MACHINES CORP. 13 Oct., 1969 [29 Oct., 1968 (2)], No. 50155/69. Heading F2U. An arrangement for mounting a tape reel on a driving hub comprises reel-engaging members which, in one position, are withdrawn within the hub periphery to allow insertion of the reel, and in a second position protrude from the hub to position the reel axially on the hub. The reel mountings shown are similar to that described in Specification 1,078,417, in which a resilient ring 22 on hub 15 is expanded to grip the reel 14 through a bevelled-edge cover 16 movable axially by a cam lever 17 attached to the drive shaft 12. As shown in Fig. 3 hub 15 also carries a series of radial slide bolts 20 with cross pins 48 connected to radial and longitudinal loading springs. Reel 14 is moved axially to clear a series of spring-loaded balk pins 88 and operation of cam lever 17 first causes a bevelled cam surface on a rib 74 formed on cover 16 to engage cross pins 48 to move bolts 20 outwardly so that their recessed ends engage the side of reel 14 against the action of the radial loading springs. On further movement the longitudinal springs urge the reel against a retaining hub flange 30, and the bevelled edge 40 of cover 16 expands ring 22 to engage the interior surface of reel 14. In the arrangement shown in Fig. 8, the inner ends of radial slide bolts 21 are engaged by an axially movable cam ring 25 actuated by lever 17.

Title: Analysis by bombardment with a beam of chemically reactive ions
IPC: G01N23/225
Filed: 1968-10-28
Abstract: 1,213,534. Ion beam apparatus. APPLIED RESEARCH LABORATORIES Inc. 28 Oct., 1968 [30 Oct., 1967; 12 July, 1968], No. 51066/68. Heading H1D. In a method of chemical analysis by bombarding a material to be analysed with a beam of primary ions to sputter atoms of the material from its surface as secondary ions and mass spectrometrically analysing the secondary ions, the primary ions are ions which are chemically reactive with the material to be analysed under the conditions of bombardment, e.g. ions of C, N, O, F, Cl or I in order to increase the availability and stability of yield of ions for analysis particularly in comparison with the use of primary ions of one of the inert gases, e.g. A or Xe. Graphs are given showing ion output against time in respect of the bombardment of aluminium, zinc and stainless steel targets with positive atomic or molecular oxygen ions to produce aluminium ions, zinc ions and chromium, iron, nickel or silicon ions respectively. Also mentioned are targets of Ti, Si, Mg, Fe, Ag, Mo, C, W, Zr, Mn, Cr, Sn, Pb, Bi, Ni and Cu. The analysing instrument may comprise an ion microscope or ion probe system coupled to a mass spectrometer. The ion source for the primary ions comprises a duoplasmatron in which the aperture 90 in intermediate electrode 86 is offset slightly from coaxial alignment with the cathode 80-a favourable arrangement for the production of negative ions. The tubular cathode 80 has electron emissive material on its inner wall. The source also includes an anode plate 94 having its aperture aligned with the axis of the cathode 80 and fixed upon an iron plate 94, a tubular acceleration tube 108 and a shielding tube 110 which supported on a bellows assembly 112 for axial adjustment. Dynamic air cooling is provided by a fan 104. A constricting magnetic field between intermediate electrode 86 and anode 92 is produced by annular ceramic permanent magnets 114 mounted between iron plate 94 and an iron plate 116. The reactive element used in the source is preferably diluted with an inert carrier gas e.g. A or N.

IPC: G03C7/14
Abstract: 514,095. Kinematograph projectors. OPTICOLOR AKT.-GES. Jan, 24, 1938, No. 2320. Void. Convention date, Jan 29, 1937. [Class 97 (i)] In kinematograph projection apparatus, particularly for use with lenticular films, a field lens 1, Fig. 2, is mounted adjacent the film in a readily-removable manner, and so that it remains fixed in the optical axis during centring of the image. In the case of a removable film gate, which is not adjusted for centring the image, the lens may be mounted in a recessed aperture in the gate itself, in which it -is retained by the film guides 3 which overlap its edges. When the film 'has a sound track at one side, so that the aperture does not extend to the film guide, the lens may be retained at this side by a strip 6 separate from the film guide. If necessary, a portion of the film guides may be raised to enable the film to clear the lens. When the film gate is adjustable for centring the image, the field lens is displaceably mounted in it and connected to. the fixed framing member so that it does not move with the gate. In the form shown in Fig. 4, the lens 19 is held in a frame 20, which frames the image, and which slides beneath the film-guide 21 and a strip 22, and is retained in position by means of a recess in it in which engages a pin 24 carried by a spring 25 which is fixed in relation to the objective. The gate 18 can thus be adjusted vertically to centre the image without moving the frame 20' and lens 19. In another form, the field lens slides downwardly into a slot in a fixed framing member adjacent an adjustable gate. The lens may be of plano-convex form, and be made of heat-resisting 'glass, and may be cooled by an air current passed between the film and the gate or on the side of the film remote from the lens.

Title: Electro-cardiographic displays
IPC: G01R13/22
Filed: 1970-10-29
Abstract: 1328157 Cathode-ray tube displays AMERICAN OPTICAL CORP 29 Oct 1970 [29 Oct 1969] 51445/70 Heading H4T A signal waveform, specifically an electrocardiographic (ECG) signal displayed on a cathode-ray storage tube by deflection modulation of a time base trace (produced by a writing beam) is continuously erased over one or more sections immediately "in front" of the writing beam. The storage tube may be of the kind having a segmented back plate sandwiched between the storage target layer and the tube face plate, the application of a negative pulse to a particular segment causing erasure of the display on the adjacent section of the target, (Figs. 1 and 2, not shown). Alternatively, additional horizontal deflection plates may be employed in a conventional storage tube to arrest the beam from flood guns at desired locations, the display at such locations being erased. Fig. 3 shows an embodiment employing the former type of storage tube in which the back plate is divided into ten sections 30-1 ... 30-10 each being connected to the output of a respective gate 50-1 ... 50-10 having as a first input, the output of an erase pulse generator 52 in common and as respective second inputs, the output a detector 54 which detects the fly-back of the horizontal sweep generator 64 (controlling the sweep of the writing beam) and the outputs of nine comparators 56-2 .... 56-10 which respond to various level of the sweep output sawtooth from generator 64. The outputs of the fly-back detector 54 and of the comparators are also supplied to an OR gate 58 so that an erase pulse 53 is generated on the occurance of the fly-back and on the occurance of the successive outputs from the comparators, it being arranged that a particular section is pulsed to cause erasure when the writing beam is in the centre of the preceeding section. Several sections "in front" of the writing beam may be erased simultaneously. When the same ECG signal is to be reproduced at a number of locations economy may be realized by employing a single small and thereof inexpensive storage tube of the type employed in Fig. 3 which is "viewed" by a television pickup tube (for employing a storage tube with reading facilities) the resulting video signals being distributed to the various locations of which they are reproduced on relatively inexpensive television receivers. (Fig. 4, not shown).
