Abstract: A stowing system with adjacent lockers comprising a portable device allowing to dialogue with a control and operating device associated with a group of lockers through the medium of a wireless preferably infrared radiation connection so as to enable a system-running person to perform particular functions the system being applicable in left-luggage locker appliances used in particular in railway stations and/or airport terminals.

Abstract: A storage system with adjacent lockers comprising a keyboard-visualizing display screen connected to a microprocessor device and enabling an attendant to record the identity of a user; a dispenser device for delivering to the user a ticket onto which are stored at least the number of the locker assigned to the user and his identity and a device associated with each locker for receiving and reading the ticket, said system being applicable in railway stations or airports.

Abstract: A stowing system with adjacent lockers comprising a microprocessor device connected to a display device and to a key-board enabling the user to compose a personal secret code transmitted to the microprocessor device which operates the locking of the lock of the door of the selected locker, this code being stored in a storage of the microprocessor device for the whole period of occupation of the selected locker.

Abstract: A member for controlling a device of the type shaped as a pivoting lever mounted in a case so that at least one end thereof may swing between a position retracted into the case and a position in which it would project at least partially from the case to be visible, at least one portion of the outer surface of the visible part of that end being colored to show the operating state of the device colored surface of the indicating portion is the surface of a separately made piece and the lever end is shaped to allow a removable assembling of the piece onto the lever, this being applicable to an electric switch operating handle or grip.

Abstract: An automatic control device consists of a signal processing unit such as a microprocessor, two buses switchable alternately, two output demultiplexers, each associated with a bus, a device for generating an output signal of the automatic control device, having two states indicative of correct operation of the automatic control device and of a failure in the operation thereof, respectively.

Abstract: The present invention relates to a device for locking and releasing objects intended for public use, such as luggage carts, and comprising a slide constituted by two portions, a first portion, and a second portion separated from the first portion by an intermediate or shim element adapted to be displaced out of its housing by a component such as a magnetic key to allow the first portion to be displaced, by a pulling action exerted thereon, with respect to the second portion to thus unlock the object locked between two adjacent objects.

Abstract: The present invention is directed to a device for locking and releasing objects intended for public use, such as luggage carts which can be taken from a common stowage space and returned to the same. The device comprises a locking apparatus allowing each object to be automatically locked to an adjacent object or to a fixed point in compact storage position. A coin or the like is introduced into the locking apparatus to allow unlocking of the same and the concomitant release of the object by exerting a pull thereon. The locking apparatus returns the coin when the object is returned to the stowage space and is locked to an adjacent object or to the fixed point. Unlocking of the object is accomplished by just exerting a pull thereon after the coin has been appropriately inserted into the locking apparatus.

Abstract: The invention relates to a workpiece-holding device provided with fastening means for fastening, by tightening, clamping or the like, the workpiece through the medium of compressed-fluid power-cylinders incorporated in the device, fed from the fluid pressure generator actuated by a source of power comprising said pressure generator incorporated in the device, the source of power being also advantageously incorporated in the device which is thereby self-contained and of reduced overall dimensions. Moreover, at least one valve assembly for the delivery of compressed fluid from the pressure generator at a predetermined pressure may be associated individually with one of the power-cylinders so that each power-cylinder operates either at a pressure independent of the operating pressure of the other power-cylinders or at different times. The invention is useful particularly for machines.
