Patent GB-408764-A (GB)
IPC: G03C7/20
Abstract: 408,764. Colour photography. HUDELEY, V., 50, Boulevard Victor-Hugo, Clichy, Seine, and LAGRAVE, J., 147, Avenue de Clichy, Paris, both in France. Jan. 12, 1933, Nos. 1048, 1049, and 1050. Convention dates, Jan. 12, 1932, Feb. 20, 1932, and May 21, 1932. [Classes 97 (i) and 98 (ii).] An optical system for reproducing three monochrome images corresponding to colour selection filters, as a single image on a lenticular film comprises three small identical objectives arranged in triangular formation in front of a single objective, the front lenses of the small objectives facing the front lens of the single objective. Preferably the focal length of the small objectives r, v, b, Fig. 3, is half that of the single objective O. The monochrome original images are arranged in triangular formation on a film C D, so that the optical axes of the objectives r, v, b pass through the centres of the images. Under these conditions a single image is formed on the lenticular film A<1> BI. A diaphragm of the form shown in Fig. 7 may be used with the system. The system may be used to reproduce a lenticular film on a lenticular film by first producing three monochromes from the original film by means of the system. Specifications 286,684, [Class 97 (i)], and 388,062 are referred to. The Specification as open to inspection under Sect. 91 describes also the use of a Galileo lens or a tele-objective for the single objective; includes a numerical example of a suitable lens system; and states that the optical system may be used for taking the original set of monochromes. This subject-matter does not appear in the Specification as accepted.

In a column-mounted gear shift mechanism a sliding-turning control member 11 operates the shift rod 19 of a transversely mounted gearbox 21 through a longitudinal intermediate rod 14. The lower end of a rod 4 inside sleeve 11 has a ball joint connection 5 with a crank lever 17 whereby sliding movement of the rod is converted into rotation of rod 14, while the sleeve 11 is rigidly connected by a second crank lever 16 pivotally connected to rod 14 so that rotary movement of sleeve 11 converted into sliding movement of rod 14. The other end of rod 14 operates a similar pair of crank levers 22, 24 which convert the movements of rod 14 into the desired movements of the shift rod 19. In a modification, Fig. 7 (not shown), a Hooke's joint is incorporated between the crank-lever 17 and the rod 14.

Abstract: 1275604 Intruder alarms H D EAKIN 26 Aug 1969 [4 Sept 1968 30 June 1969] 42548/69 Heading G4N An alarm system is arranged to be operated in response to a predetermined number of intermittent signals within a given frequency band but not by continuous signals. As shown, transducers 1, 3, 5 are arranged to respond to sounds in the region being protected and feed an amplifier 7 the output of which is fed to a bandpass filter 9 and a rectifier 13. Relays 15, 17 are energized by signals within the pass band, energizing relay 27 which is held in by contacts 31. Contacts 29 start a motor 35 driving a cycling device 37 at 1 r.p.m. After 1 second, relay 27 is released by contacts 43; after two seconds contacts 41 energize relays 47, 25 and 49. Contacts 51 and 53 energize a motor 57 driving a cam 59 at 0À5 revs per second. After one further second, contacts 55 close and if signals are no longer present, contacts 63 will be closed so that stepping switch 65 will be pulsed via rectifier 81. After two seconds, contacts 55 open, stopping motor 57. If further pulses of appropriate frequency occur, stepping switch 65 is stepped on until after a predetermined number of steps (determined by switch 71), relay 69 is energized, operating alarm 73. Relays 125, 129 and 131 avoid the possibility of advancing the stepping switch 65 at the end of a noise duration longer than one second.

[Also in Division B6] A record tape passes over guides 38-40 between a magnetic yoke 32 and a pair of armature members 29 and 30 each forming a brake and is driven past a read-out device 27 by a feed roller 12 co-operating with a pair of pressure rollers 16, the arrangement being characterized in that each of the members 29 and 30 and each of the pressure rollers 16 can yield independently to variation in thickness of the tape, e.g. due to a joint in the tape. The pressure rollers 16 are mounted on respective shafts 14 and 15 and are jointed together by a cross-shaft 13 by means of which they can be pivoted in the vertical plane to bring the rollers into or out of grip with the tape. Each roller is normally held lightly against the tape by a spring, Fig. 3 (not shown), and both rollers may be pressed into driving grip when a winding 26 is energized to attract respective armatures carried by the shafts 14 and 15. The brake construction is similar with the two armatures 29 and 30 pivoted on a shaft 31 and normally pressed lightly on to the tape by respective springs, Fig. 2 (not shown). Energization of winding 33 attracts both armatures into braking engagement with the tape. If the tape is to be held stationary during read-out the windings 26 and 33 are energized alternately at speeds of up to 1000 characters (i.e. readings) per second.

Potentiometer Pc is driven through a reduction unit 7 and clutch 8 by a stepping motor 2 which may be energized by a transistor relaxation oscillator, Fig. 2 (not shown), of which resistor (18) represents one of a number of selectable resistors of different value. Output from a high resistance potentiometer 1 on the same shaft is applied to a comparator 9 together with one of a series of reference voltages S1-S3 selected by a switch 21. The passage of the difference voltage output from comparator 9 through zero initiates operation of timing device 24 which determines the duration of any stage in the programme and also operates switch 21. Each stage may be timed by circuit illustrated in Fig. 3 (not shown) through a relay (16). Two such stages as shown in Fig. 3 may be cascaded the first operating after a period of hours which triggers a second which operates at the end of a period of minutes.
