Abstract: ABSTRACT Rear discharge refuse collecting vehicle has a refuse container packed, for example, by a hydraulic packer mechanism in a pivotally mounted tailgate. A refuse pushing member is mounted for sliding movement by an inclined hydraulic refuse pushing ram to push refuse out of the container under the raised tailgate. The refuse pushing ram acts between the refuse pushing member and a short upstanding hollow fabricated steel cantilever just behind the vehicle cab at the front of the container. The cantilever is mounted on a support frame under the refuse container, and extends into a recess defined by a rearwardly sloping lower portion of the refuse pushing member whereby the cantilever occupies no space which would have been available for refuse, and the refuse pushing member can be fully retracted to the front of the refuse container and the container itself is not stressed by the ram.

Abstract: ABSTRACT    A key-operated device, for example for controlling access to switch gear or potentially dangerous machin-ery, has a rotary motion with an axially inserted key but  departs  from the usual barrel lock construction which is sensitive to foreign matter.  Instead it has a faceplate in front of a stationary body with a cylin-drical member rotatable in it and having a recess for the key and circumferentially spaced notches in a flange close behind the plate and prevented from direct access through the keyhole by a fixed axially extending wall on the back of the plate but accessible by appropriate lugs on the key when the latter is inserted.  The rotatable member is connected through a spindle to a switch, valve or latch or other actuated device.

Abstract: ABSTRACT         An electronically controlled indicating and testing device for printing the value with franking machines is disclosed, the device comprising a micro-processor, with a plurality of stores, and electronic position-checking devices for the mechanical printing units.  By means of the latter, the digits of the value to be printed, and the print selector, are compared with the values displayed and the check-symbols in the digital display, and the value is printed only if these agree.  Moreover, the brightness of the digital display adapts automatically to the lighting in the area. Further-more, empirical values relating to wear in mechanical components are stored. After the unit has been in operation for a certain length of time, or after a certain number of printing operations, these values release a signal indicating that the franking machine requires technical maintenance, and may, if necessary, halt the printing.

Abstract: METHOD OF CONTROLLING SCRAMBLING AND UNSCRAMBLING IN A PAY TV SYSTEM.     Abstract of the Disclosure Scrambling of a video signal in a pay TV system is effected in dependence upon a first variable which is changed recurrently, e.g. monthly, and a second variable which changes from field to field.  For each field the second variable and other data are transmitted simultaneously with the video signal together with check data produced from the transmitted data and a third variable which is changed recurrently.  The first and third variables are recurrently transmitted to each authorized subscriber station, encoded in dependence upon a subscriber number stored in the subscriber station.  In the subscriber station, unscrambling is effected in dependence upon the stored first variable and the transmitted second variable after the transmitted data is checked using the check data and the stored third variable.  The first variable is conveniently different for different types of television programs, the type of television program being identified by the other data transmitted simultaneously with the video signal.     - i -

Abstract: L'invention concerne la synthèse de l'ammoniac où un courant gazeux d'hydrogène brut incorporant de l'azote et des impuretés telles que monoxyde de carbone, argon et méthane est soumis à un lavage à l'azote liquide avec refroidissement du courant d'hydrogène brut et d'un courant d'azote à une pression peu supérieure à celle du courant d'hydrogène. Au moins une partie du courant d'hydrogène est introduite en tête d'une colonne de lavage et une autre partie également refroidie est adjointe au courant de gaz lavé. Le refroidissement des deux courant d'hydrogène brut et d'azote s'effectue par échange thermique avec le courant de gaz lavé soutiré en tête de la colonne de lavage et avec un courant résiduaire essentiellement constitué d'azote et des impuretés soutirées en cuve de ladite colonne de lavage. Le courant partiel d'azote refroidi destiné à être adjoint au courant de gaz lavé est adjoint au courant de gaz lavé alors que ce dernier a été réchauffé à une température intermédiaire, qui est suffisamment basse pour que l'essentiel de l'effet cryogène lors du mélange soit obtenu, mais est cependant en tout cas suffisante pour que la température du mélange ainsi obtenu soit supérieure à la température de rosée dudit mélange. Installation pour la mise en oeuvre de ce procédé. On profite ainsi de l'essentiel de l'effet cryogène dû à l'effet de mélange azote-gaz lavé sans pour autant provoquer la formation d'un courant diphasique très difficile ensuite à réintroduire de façon homogène dans l'échangeur.
