Abstract: 134,956. Crocker, F. Nov. 20, 1918. Compound road vehicles.-Relates to a three or four wheeled tractor adapted to be coupled to the front end of a four-wheeled trailer so as to form a compound vehicle. The rear end of the tractor has a cross-bar J to which side bars C are pivoted, the front ends of the side bars being adjustable in height by a hand-wheel device A. The front wheels of the trailer are mounted on a U-shaped axle carried by brackets E fixed to the springs, the bent ends of the axle being normally secured vertically by a stop P and pivoted locking-piece G.

Title: Process for producing colour films by subtractive synthesis and its application to sound films
IPC: G03C7/24
Filed: 1946-05-13
Abstract: 616,362. Colour photography. DEGUIGNES, M. May 13, 1946, No. 14344. Convention date, May 11, 1945. [Class 98 (ii)] A double sided film is exposed, in register, to negatives selected for the green and orange colours of a scene, developed and fixed to produce positive silver images, treated with chlorine and then with thioindoxyl and indoxyl respectively so as to produce purple and bluegreen indigoid dye images together with silver images, after which the silver images are removed and an image of yellow colour is superimposed on one of the indigoid images by sensitizing with an alkali diazo sulphonate and. a coupling agent such as 1 phenyl 3 methyl 5 pyrazolone and exposing to light through the negative selected for the violet. A sound track may be printed after printing the two silver images. In practice the latter two images are printed simultaneously in presence of an intermediate removable red or yellow separation layer and then the sound band is printed preferably on the side which is to be blue-green; all three latent images are processed to silver and dried, the side of the film which is to be purple is imbibed with water by passage over a wetted roller, and the film is passed in a container of convenient shape which is filled with chlorine, to transform the moist silver image into silver chloride. Excess chlorine is removed by sodium sulphite, the silver chloride is exposed by means of a mercury vapour lamp and this image is developed by immersion of the whole film in a bath containing thioindoxyl alkalised by caustic soda and protected against oxidation by sodium sulphite, to give silver and thioindigo red images. Similar treatment is effected to the other side of the film except that the picture area only is wetted and indoxyl or if desired 4-chloroindoxyl is used instead of thioindoxyl to produce indigo blue or 4-4<1>-dichlor indigo, respectively. Silver is removed from the picture areas by acidified permanganate or bichromate, ammonium persulphate or the former mixture applied by a roller the full width of the film on the side of the purple image and of width of the picture areas only on the side of the blue-green image, to leave the sound track in silver, or in an alternative procedure the sound track may be constituted by silver together with blue-green dye. The film is then impregnated on either side with an alkaline mixture of a diazosulphate such as orthochloraniline diazo sulphate and a coupling agent such as 1 phenyl 3 methyl 5 pyrazolone and exposed through the remaining negative record to give the yellow image.

Containers for roll films.-Alight-proof chamber, adapted to admit developing &c. liquid when immersed in successive baths, is provided with means within the chamber for winding in the film, said means being adapted, when rotated in the reverse sense, to spread the convolutions of the film so as to permit the liquid to act upon the surfaces thereof. In the form shown, a cylindrical casing 1 is closed at its ends by a base 2 supported on feet 3 and a cap 6, these two members being held in position respectively by a thumb-nut 5, and a knob 8 engaging extensions 4<x>, 4<xx> of a drum 4 adapted to rotate inside the casing. The nut 5 is screwed directly upon the extension 4x, while the knob 8 is held against the extension 4<xx> by a flange 7<xx> on a threaded stub 7 screwed into the extension. After withdrawing the stub 7 and removing the cap 6, the film is introduced into the chamber from its container 11 through an aperture b, light-trapped by rubber lips 10, and its end is secured in a slot c in the drum 4 and held therein by rotating a locking cam 15. The cap being replaced, the film is drawn into the chamber by rotating the drum 4, and its convolutions are opened out by giving a reverse rotation to the drum. The apparatus is placed in a tank containing developing &c. liquid, winch is admitted to the chamber through inlets 16, radial passages 17, via an annular passage 18 to radial passages 19 which discharge into the chamber through ports 20. The passages 17, 19 are arranged in both the base 2 and the cap 6, alternating with each other circumferentially in both members. During treatment of the film, the liquid in the chamber may be agitated by rotating the drum first to wind up the film and then to unwind it.

Title: Transceivers

Filed: 1976-04-09
Abstract: 1501338 Transceivers RONALD TRADING CO Ltd 9 April 1976 14511/76 Heading H4L The transmitter circuit of a radio transceiver is provided with a key SW2 for selectively modulating the transmitted carrier frequency by a control frequency and is provided within the receiver circuit with a light source LED and means capable of energizing the light source in dependence upon the presence of the said control frequency in the received modulated carrier frequency. As shown, in the receiver mode an audio modulated signal at antenna 10 is applied to a conventional r.f. circuit, including a transistor TR1 the output from which drives a loud-speaker LSI, associated with an audio output transistor TR6, by way of switch contacts SWIC, a capacitor C7, a volume control URI, and a switch SW3 which can be moved to a second position so that a light emitting diode LED is put into circuit rather than the loud-speaker, whereby the LED is energized by way of transistors TR3, TR4, TR5 so that a light output is produced in dependence upon the audio signal. In the transmit mode for speech signals, switch SW1 is changed over and the loud-speaker LS 1 acts as a microphone whose output is amplified by transistors TR2 and TR6 and applied via contacts SWIC to the r.f. stage which, by virtue of the position of the contacts SW1A and SW1B of switch SW1, functions as an oscillator controlled by a crystal XTL, the signal from contacts SW1C modulating the oscillator output to produce a signal for transmission on antenna 10. If, instead of speech, the transmission is to be effected by, for example, morse code, the key SW2 is opened and closed manually, whereby positive feedback from transistor TR6 to transistor TR2 produces an oscillatory signal which is applied to the r.f. stage so that the antenna 10 radiates a signal modulated with an audio signal only when the key SW2 is closed.
