Abstract: 1386465 Vapour disseminator CLINE BUCKNER INC 7 Nov 1972 [22 Nov 1971]  51331/72 Heading A5G [Also in Division F4] Apparatus for disseminating deodorizing, disinfecting and like vapours comprises a louvred casing 11, 12 containing an electrically operated fan 16 and a source of volatile material 27. The fan operates intermittently, receiving power from a battery 21 via a transistorised timing circuit (Fig. 3, not shown), which allows the fan to operate for short periods between other periods during which vapour from the source 27 disperses throughout the casing. The vapour source is preferably a gel which slowly evaporates and is associated with a syneresis pad (see Figs. 2A, 2B and 2C, not shown) which absorbs liquid exuded from the gel during shrinkage and which compensates to some extent for the decrease in surface area of the gel during use.
Patent GB-1513930-A (GB)
Title: Battery voltage detecting device
IPC: H03K17/30
Filed: 1975-12-16
Abstract: 1513930 Battery voltage monitoring DAINI SEIKOSHA KK 16 Dec 1975 [20 Dec 1974 24 Dec 1974 (2)] 51451/75 Heading G1U [Also in Division H3]  Two MOS FET's are connected in series and operated as a voltage threshold circuit in order to monitor the voltage of a battery, particularly a watch battery. As described to monitor a battery 1, Fig. 2, two FET's 4, 7 are connected across the positive Lp and negative Ln supply leads from the battery and a switch 2 is actuated to connect terminals B and C. FET 4 is then in a potentially conductive state (having a negative gate-source voltage) so that if the battery voltage is sufficiently high for the drain-source voltage across FET 7 to cause conduction with a zero gate-source bias voltage, then conduction occurs, and a terminal D goes low thereby causing an output terminal 11 to go high. As the battery voltage falls, eventually the drain-source current of FET 7 will fall rapidly from its substantially constant value towards zero, and when this occurs the voltage at D will fall to about one-third the battery voltage then existing causing the output terminal 11 to fall. In a second embodiment series-connected FET's 20, 21, 22, 23, Fig. 4, act as a potential divider to apply half the battery voltage to a series-connected pair of FET's 25, 26. When the battery voltage is sufficiently high, both FET's 25 and 26 will conduct, with FET 26 conducting the greater since its gate-source voltage will be twice that of FET 25, and hence a terminal E will be at a low level and an output terminal 11 will be high. As the battery voltage falls, FET 25 conducts more strongly and eventually terminal E rises and terminal 11 falls.

Title: Automatic-control apparatus for machine tools

Filed: 1971-11-08
Abstract: 1362819 Gauging ING C OLIVETTI & C SpA 8 Nov 1971 [7 Nov 1970] 51814/71 Heading B3B [Also in Division H2] An automatic control apparatus for a machine tool, having a cutter-head or work-head movable by an electric step-by-step motor, comprises a pulse counter for the step pulses which is reset to zero in any predetermined resetting position of the head. As shown, a machine tool comprises a head 3, on which a tool (not shown) is mounted, slidable on a platform 12. A double-acting hydraulic cylinder 14 is mounted on the platform 12 so that by selective electrical operation of valves EV1, EV2 a piston 20 is displaced to rapidly move the head 3 by a rod 19. The motion of the rod 19 is transmitted to the head 3 through a micrometric adjustment device comprising a nut 16 co-operating with a screwed portion 18 of the shaft 19. The screw is displaced within the nut 16 by rotating the rod 19 through a spline, by gears 22, 24 from a reduction gear 25 driven by an electrical step-by-step motor 26. Alternatively, the gear 24 can be manually driven via a shaft 26. The sequenced energization of the valves EV1, EV2 and the forwards/backwards pulse rates to the motor 26 are determined by an electronic logic arrangement responsive to manual dimension setting devices and preset working cycles. The preset working cycles comprise (a) a setup cycle whereby the starting zero position is fixed from which subsequent cycles are begun; this is attained by bringing the tool into contact with the workpiece, (b) a machining cycle in which roughing and finishing cuts occur at differing speeds determined by logic selected pulse generators; upon completion of the machining cycle the tool is maintained in contact with the workpiece without a feed occurring for a predetermined period; and (c) a cutting-in-air cycle for rapid feed to a position outside the maximum tolerance on the diameter of a number of similar piece-parts. Facilities are also provided for tool regrinding and compensation of the starting zero-position for the consequent change in tool dimensions.

Title: Portable hand holdable device for displaying textual information
IPC: G09G3/20
Filed: 1975-12-18
Abstract: 1502508 Displays; reading-training device YOUNG COMMUNICATIONS CORP 18 Dec 1975 [30 Dec 1974] 51888/75 Headings G4H and G5G A portable hand-holdable device comprises means adapted to receive a removable store, and display means for displaying information from the store in a line. As disclosed, the removable store is a magnetic tape eassette, digital information from it being transferred block by block (under control of "end-of-block" codes) via a tape buffer memory to a process memory (both being dynamic shift register loops), the characters being supplied in turn from the process memory to an 8-bit shift register feeding a ROM dot pattern generator, dot columns from which pass into shift registers (one per dot row) the stages of which control LEDs of a display (for displaying a line of characters in dot matrix form), so that the characters advance across the display. The display is not illuminated until the first word reaches an index mark just to the left of the half-way point, under control of a word index shift register which has a bit per character position to indicate character or space. A manual speed control controls the frequency of a clock oscillator to control the time each word is displayed next to the index mark before being shifted on and replaced by the next word. The speed control includes a stop setting. A manual word time expansion control permits the display duration of each word longer than 4 letters to be increased by selectively 0%, 6% or 12% of the time for a 4-or-less-letter word for each letter in excess of 4. Word length is specified by the contents of the word index shift register. A manual brightness control is provided, but variation of apparent brightness with display time is avoided by automatic correction in dependence on the other two manual controls above and the word index shift register. Instead of increasing the display time, for the longer words, the blank time between words may be increased instead. The device may be used for improving reading speed.
