Title: Card synchronized timing unit
IPC: G06K7/016
Filed: 1955-12-19
Abstract: 779,518. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 19, 1955 [Dec. 30, 1954], No. 36308/55. Class 106 (1). [Also in Group XL (b)] A timing control means for statistical apparatus wherein data contained on moving record cards is sensed by sensing means, comprises means disposed in predetermined positional relationship with the sensing means for providing a signal indicative of the position of a card being sensed. As shown in Fig. 1, the card 14 is fed along a track 12 and passes over a line of photoelectric cells 16 adapted to sense each column of the card in turn. The timing control is provided by a timing " ladder " 18 comprising a predetermined number of narrow, spaced photoconductive strips. A tubular light source is located above the timing ladder. As the card passes over the sensing cells 16 the leading edge covers the timing ladder, strip by strip. The ladder is so arranged that the strips are each covered by the leading card edge as the card moves between column sensing positions. The photo-conductive material decreases in resistance when illuminated and vice versa so that a resistance curve as shown in Fig. 6 is produced, rising in steps. The timing ladder is connected in an electronic circuit which converts the steps of change in resistance to discrete electrical impulses for synchronizing the associated statistical apparatus. The steps of change of resistance get less as the resistance rises but this may be compensated for by making the voltage applied to the light source above the ladder depend on the total resistance of the ladder. The light source thereby becomes brighter when the steps of change in resistance of the ladder are small and vice versa. This provides a series of spaced electrical pulses of uniform amplitude.

Abstract: 1318098 Electron beam storage tube GENERAL ELECTRIC CO 31 July 1970 [6 Aug 1969] 37121/70 Heading G4A [Also in Division H1] An electron beam storage system for permanently storing data at a density exceeding 10<SP>9</SP> bits/cm<SP>2</SP>, comprises a cathode 50, Fig. 6, having an extremely small emissive surface, electrodes 8 and 9 for providing a hemispherical electric field about the emissive surfaces with a gradiet high enough to produce a high density emission current of about 1000 A/cm<SP>2</SP> which is formed into a divergent beam; a first focus lens 10A for producing a parallel beam; a second focus lens 10B for converging the beam at a spot of about 0À1 microns diameter on the storage medium 1; deflection means 11 for deflecting the beam over the storage surface; and modulation means such as the deflection coil 12 for modulating the beam intensity. Spherical aberration in the focusing system is reduced by locating the cathode at the focal point of the first lens 10A and the storage surface at the focal point of the second lens 10B, and an astigmator coil 64 is located in the vicinity of a beam limiting aperture 58. Two pairs of centering coils 65 mounted on the wall 66 of the continuously-evacuated chamber adjust the beam to pass through the centre of the second focus lens. The storage target may comprise strips of a selenium-arsenic alloy deposited on a p-i-n substrate (Figs. 2 and 3, not shown). The beam impinges on the edges of the strips and evaporates the alloy if it is at maximum intensity, so that the data may be recorded as a pattern of indentations on both edges of each strip. For reading, the pattern the beam is operated at low intensity and the output is taken either from the electrons which pass through the indentations to the substrate. Alternatively the substrate may be of glass and the output is derived by secondary emission or by reflection from the target to a detector positioned above the storage surface. The beam can be deflected over a data block area, and 44,000 data blocks may be provided on a substrate which is movable from outside the envelope to bring a desired data block into position (Fig. 10, not shown).

Abstract: 953,239. Rotary vacuum filters. DAVEY, PAXMAN & CO. Ltd. Sept. 26, 1962 [Oct. 17, 1961], No. 37157/61. Heading BID. In a rotary vacuum filter, the pressure medium is used to inflate pressure elements acting mechanically to press the filter cake against the filter medium at appropriate points in the operating cycles. Slurry is fed to a filter trough 2 where it may be kept in suspension by a mechanical agitator. A vacuum is applied to the inside of the filter leaves 1 via ports 4 which communicate with a hollow trunnion (not shown) for the axial rotating member 5, application of the vacuum being controlled by an automatic valve head of known type. Thus liquid is drawn through the filter medium 3 while the solids build up as a filter cake on the flat surfaces of the rotating leaves 1. As the cake emerges from the trough, the action of the internal vacuum in removing moisture from the cake is enhanced by inflation of the inflatable pressure elements 7, made of reinforced rubber or other flexible material impervious to gas or liquid at the required working pressures, which rotate continuously and uninterruptedly with the trunnion and leaf assembly, their interior spaces communicating with an internal pressure line 8, thus exerting a pressure of up to several atmospheres on either side of the cake. The filter leaves may have a selvedge consisting of an impervious non-filtering surface which acts as a seal between the leaf and the pressure element. On completion of the compression of the filtered material and just before the cake discharge point is reached the pressure elements are deflated by releasing the internal pressure or by pumping out and the cake is then discharged, e.g. by blow-back air or steam pressure applied to the inside of the filter leaves. The inflatable pressure elements may be filled with liquid instead of gas if desired. In an alternative form, not shown, the pressure elements are stationary and the leaf assembly rotates intermittently. Thus non-rotating pressure elements may be withdrawn from the spaces between the rotating leaves for part of the filtering cycle and inserted into these spaces for other parts of the cycle.
