Abstract: The inclination angle of a keyboard is made infinitely adjustable between preset maximum and minimum angles to suit individual operator and work place needs by means of an adjustment assembly. The assembly calls for selectably setting cam plate housing seats located at one end of the keyboard to increase or lower the angle of inclination.

Abstract: A push-button key switch for keyboards, having an actuating member, and a helical spring which functions as a return spring for the actuating member and as a movable contact element. The helical spring comprises two sections, one of which is employed as the return spring, and which engages a seating surface on the actuating member. The other section of the spring extends beyond the seating surface and is adapted to engage a cooperable stationary counter-contact upon actuation of the actuating member. The switch may be readily designed as a single pole-single throw switch or a single pole-double throw switch, and may be designed to provide predetermined contact pressures between closed contacts.

Abstract: A console for apparatus such as teleprinters including a box-like base or housing for housing the apparatus, a plate which is hinged to one side of the base and arranged to serve as a cover member in the housed condition of the apparatus and as a supporting surface in the ready for use condition of the apparatus, and bracket structures attached to the base which include upper and lower supporting portions.

Abstract: A device for recording characters on a recording carrier uses mosaic recording mechanisms. In addition to the recording of the characters in the required character height, additional recording members are arranged in the recording head and a control device for the mosaic recording mechanism is constructed in an expanded manner so that alternately a height-extended character formation can be executed over all recording members. The device is suitable for recording capital and small letters, and the control apparatus is constructed so that all alternatively the capital letters and numerals can be recorded in an extended manner by an additional amount provided for the short heights of the small letters. The control apparatus for each of the two character heights to be formed by the mosaic recording head has its own character generator and switching means are provided so that the two character generators can be alternately effective for activating the mosaic recording head.

Abstract: The invention contemplates wireless remote-control of a camera or the like, as from within the field of view of the camera, and using control radiation which is essentially outside the spectral response of the camera. Control is effected by selective operation of a pulsed transmitter of the control radiation, and by generating in a receiver at the camera an electrical signal for camera control. Various modifications and embodiments are disclosed, including selective remote-control of one or more different camera functions.
