Title: Electrostatic recording method and apparatus
IPC: H04N1/032
Filed: 1973-04-02
Abstract: 1436335 Facsimile systems EG & G Inc 2 April 1973 [5 April 1972] 15628/73 Heading H4F  To improve the resolution of electrostatically recorded binary signals, in addition to maintaining on the recording stylus at times when the marking potential is not applied thereto a potential of opposite polarity with respect to the marking potential to thereby cancel charges deposited by the marking potential as a result of the finite size of the stylus, the increments between successive lines of the raster are made equal to a fraction of the stylus dimension in the direction perpendicular to the line scan direction. This overlapping of successive lines together with the application of a potential of opposite polarity reduces the area in which charges are deposited by the marking potential perpendicular to the line scan direction due to the finite size of the stylus in this direction thereby improving the resolution of the recording in this direction. Recordings produced by cylindrical and rectangular styli are described with reference to Figs. 3A-3E (not shown). A grey scale recording may be produced by applying during the time that each cell area is being scanned clocked binary pulses having widths modulated in dependence upon the average reflectance desired, or binary pulses whose number is proportional to the average reflectance desired, to the recording stylus, the above referred to opposite polarity potential being applied at all other times. This arrangement is claimed in Divisional Specification 1,436,336. To further improve the grey scale recording the above referred to overlapping of lines may also be effected, preferably using a non-synchronous clock (Fig. 8, not shown) so that the halftone "dots" are not aligned. A detailed description of an m x n array converter is described with reference to Figs. 11-13 (not shown) which for each reflectance value desired determines which of the mn matrix areas in each cell area are to be toned black, thereby providing a grey tone resolution of m x n levels, e.g. for the 4 Î 4 array converter described four marking signals may be generated along each recording trace for each cell area, there being four such recording traces for each line scan of an original. The binary marking signals may be applied to one or more styli attached to a belt which traverses the recording medium; a helical slit co-operating with linear slit analysing system being described.

Title: Device for monitoring the charging current for a battery of storage accumulators
IPC: G01R31/36
Filed: 1974-04-09
Abstract: 1456737 Measuring battery parameters SOC NATIONALE INDUSTRIELLE AEROSPATIALE 9 April 1974 [17 April 1973] 15676/74 Heading G1U A battery monitoring circuit releases an alarm if the battery charging current continuously increases during a predetermined time period. Charging current in an accumulator is monitored by placing a small resistance 2 (e.g. an ammeter shunt) in the earth lead and measuring the voltage between its terminals. A steadily increasing charging current is used to shut-off the charging supply and light an alarm. Amplifier 3 is used to detect the voltage, a reference level being set by resistor 4. Amplifier 6 only provides a positive output if the accumulator is charging. A switch 7 is closed once per minute by control generator 8 and the voltage value is thus stored on capacitor 9. This is inverted by unity gain feedback amplifier 10 and combined with the instantaneous voltage value via line 11 in amplifier 12 which provides a positive output if the value increases. An output from gate 13 thus indicates an increasing charge current. If there is no output from gate 13, after a delay 16 (slightly less than one minute) gate 15 provides a pulse to reset counter 17. If there is an output, after the delay 16 counter 17 is incremented. If the total in counter 17 reaches three, relay 20 is energized closing switch 20a which thus latches the relay via battery 21. The charging supply is thereby disconnected and lamp 22 lights. A second embodiment, Fig. 2 (not shown) describes the control generator 8 in detail and uses NAND, NOR logic throughout.

Abstract: 1,177,629. Rolling. DAVY & UNITED ENG. CO. Ltd. 26 May, 1967 [7 April, 1966], No. 15727/66. Heading B3M. The roll gap in a 4-high mill is determined either by lands 21 (Fig. 1) at the ends of the work rolls 12, 13 or by rollers 36 (Fig. 7) acting on the suitably profiled ends of the rolls. The rollers are horizontally movable within yokes in the housings, and are driven by the work rolls. A prestressing force P is applied to the bearings of the backing rolls 15, 16 to control the pressure between the contacting lands 21 or the profiled roll ends to thereby control the roll gap. A bending moment may be applied to the journals of the rolls 15, 16 to counteract bending of the work rolls under load. Gauge control of a strip 14 may be enhanced by the additional use of a screwdown controlled in response to measured strip thickness, or by controlling the strip tension. The end portions of the backing rolls may be supported in 180 degrees hydrodynamic or hydrostatic bearings. (For Figures see next page.)
