Title: Beam addressable memory apparatus
IPC: G11C11/23
Filed: 1972-02-29
Abstract: 1336546 Digital data storage MINNESOTA MINING & MFG CO 29 Feb 1972 [1 March 1971] 9381/72 Heading G4C [Also in Division H1] In an electron beam storage system, the storage medium 7 is divided into areas each having a plurality of bit locations, e.g. an 8 x 8 matrix, and can be negatively biased to mirror a mono-energetic electron beam the crosssection of which is controlled so that the density of the mirrored beam is spacially modulated in accordance with the stored bits at a selected area to which the beam is deflected, and a detector 35 converts the density modulations of the mirrored beam into corresponding electrical signals to provide simultaneous read-out of all the bit locations in the selected area. In the write mode, an address selector 29 supplies deflection voltages to a set of four plates 20 to deflect the beam, via a prism 21 and objective lens 22 to a selected area of medium 7. Lens 22 includes an element the potential of which is adjusted to provide a beam diameter of the order of 3 microns corresponding to one bit location. The deflection voltage is then varied in steps to scan the beam along a row of bit positions in the selected area, and between steps a positive potential is applied to medium 30 as required to store data bits in the form of charged areas. All the rows of the selected area are similarly written into in turn. In the read mode the element in lens 22 has a higher potential applied thereto to increase the beam diameter to cover all the selected area and a negative potential is applied to plate 30 to mirror the modulated beam back through prism 21 and a further set of defection plates which centre the beam on the axis of a projection lens 34 forming a magnified electron image on an array of detectors 35, e.g. Schottky diodes. The signals from the detector array are fed to a buffer and control unit 43 communicating with a computer, the unit 43 also providing a feedback signal to address selector 29 to correct erroneous positioning of the beam as detected from the read-out data which may include an address.

Title: Process for the electrolytic oxidation of aldoses
IPC: C25B3/23
Filed: 1931-03-27
Abstract: 365,414. Electrolytic oxidation of aldoses. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Rohm & Haas Co. ; 222, West Washington Square, Philadelphia, U.S.A.) March 27, 1931, No. 9412. [Class 41.] Aldoses are oxidized by electrolysis with an insoluble anode in the presence of a suitable base such as calcium hydroxide, calcium carbonate, magnesium hydroxide or sodium carbonate and of a bromide or iodide to form a salt of the corresponding monocarboxylic acid. The anode may be of copper, lead, iron or nickel. No diaphragm is necessary. The electrolyte should be agitated to keep the base in suspension. The halogen salt is not consumed and may be used again. In an example 40 parts of glucose, 4 parts of potassium iodide and 9 parts of calcium hydroxide are mixed in 200 parts of water and electrolyzed in a copper cup serving as cathode with a rotating graphite anode at a temperature of 10-15 C. and current density 25 amps. per sq. ft. When the theoretical amount of current has passed, the solution is filtered and evaporated. Calcium gluconate crystallizes out. In another example sodium carbonate is employed as the base and sodium gluconate is precipitated from the electrolyzed solution by addition of alcohol. In other examples lactose is treated for production of calcium lactobionate and galactose for the production of calcium galactonate. Mixtures of aldoses and ketoses may be separated by the process, the ketoses not being oxidized. In an example, a solution containing 54 gms. of invert sugar to which is added 2 gms. of potassium iodide and 5.5 gms. of lime is. electrolyzed. After electrolysis excess lime is neutralized with sulphuric acid and the solution partially evaporated. A precipitate of calcium gluconate is centrifuged off. The filtrate is concentrated and added slowly to 6 gms. of lime in 40 c.c. of water kept at 2 C. Calcium fructosate crystallizes out. A suspension of this is treated with carbon dioxide to remove calcium carbonate, and fructose is precipitated from the filtrate by alcohol.

Filed: 1975-03-06
Abstract: 1512282 Photographic type-composing ADDRESSOGRAPH-MULTIGRAPH CORP 6 March 1975 [25 June 1974] 9445/75 Heading B6W A stepping motor 21 drives a photosensitive film forwardly in line-spacing direction from a container 35 by means of rollers 18, 19 through a one-way clutch and when reversed drives rollers 29 through a spring clutch to tend to drive the film in reverse. In operation, the film is fed forwards until the leading edge or a reference mark is detected by a photochromic sensor 30 which passes a signal to a computer 34 which stops the motor and starts the exposure procedure so that a column of lines is composed on the left-hand part of the film, the motor now driving the film intermittently for line-spacing. When the column is composed, the motor is reversed to drive the film backwards beyond the point at which the column was started, and then driven forwards until the sensor 30 again passes a signal, when a second column is composed to the right of and aligned with the first column. When the film is driven backwards, the clutch 24 does not transmit motion from the rollers 18, 19 to the motor, and when it is driven forwards, the spring clutch slips. By composing at least one character on the first column baseline, then performing the reverse feed followed by a forward feed adjusted by a fractional leading distance, subscript or superscript characters can then be composed to obtain an irregular base line comparison.

Title: Frequency discriminator apparatus
Inventor: AVINS JACK
IPC: H03J7/08
Filed: 1968-02-28
Abstract: 1,218,824. Frequency discriminators. R. C. A. CORPORATION. 28 Feb., 1968 [2 March, 1967 ; 26 June, 1967], No. 9618/68. Heading H3A. A frquency discriminator for detecting and correcting mistuning of a TV receiver and adapted to be constructed as an integrated circuit 10, comprises a limiter-amplifier 30 feeding a discriminator transformer 106 supplying two rectifier circuits 40 and 50 which supply the inputs to a differential amplifier 60 providing output voltages at terminals 110 and 111. The rectifier circuit 40 comprises two oppositely poled diodes 41, 42 coupled by resistances 43 and 44, the junction of which forms the output terminal of the rectifier circuit and is coupled by a resistance 45 to a D.C. bias source. A reverse-biased diode 46 acts as a filtering capacitor and a second reverse-biased diode 47 adds capacity to that of the anode of diode 41 to balance the higher capacity of the cathode of the corresponding diode 51 in the other rectifier circuit 50, which is of similar construction oppositely poled. The D.C. bias is derived from the emitter load 27 of transistor 24, the base of which is connected to a point on a potential divider comprising resistances 25, 26 and three transistors 21-23 connected as diodes. This bias is independent of changes of temperature or of the voltage supply since changes across the base-emitter junctions of transistor 21-23 balance those across 24, 81, 62 or 24, 71, 61. The D.C. bias supply 20 may alternatively comprise a diode (153, Fig. 3, not shown) in series with two Zener diodes feeding a resistance potential divider. In Fig. 1, the rectifier circuits 40 and 50 are coupled to the differential amplifier through respective emitterfollowers 71 and 81, but these may be omitted (Figs. 2 and 3, not shown) or replaced by Darlington connected transistors (Figs. 3 and 4, not shown). In another modification, Fig. 3 (not shown), the common emitter resistance 63 of the differential amplifier is replaced by a constant-current transistor (155). If the tuning element of the receiver is a varactor diode (Fig. 5a, not shown), the bias for the diode is derived from terminal 110 or terminal 111; if the tuning element is a transistor used as a voltage variable capacitor (Fig. 5b, not shown), terminals 110 and 111 are coupled to the base and collector of the transistor. During preliminary manual tuning the bias from terminals 110 and 111 may be replaced by the output at terminal 113 of a D.C. supply circuit 90, or the terminals may be short-circuited.
