Patent DE-3116507-A1 (DE)
Title: Ground plate for covering in particular yielding subsoils
Inventor: LEHNERT PETER
IPC: E01C5/08
Filed: 1981-04-25
Abstract: Yielding subsoils are covered with the ground plate which consists of concrete. Surfaces which can be driven on are thus obtained. The square ground plate is divided into a base plate (12) and, situated below this, a subplate (14). The subplate (14) has, in relation to the outline of the base plate (12), projecting teeth (16) and recessed tooth spaces (18). When ground plates are laid against one another, the teeth and tooth spaces engage in one another. A rigid interlocking is thus created. The great forces arising under the wheels of a motor vehicle when these ground plates are driven on are thus distributed over a large area on the subsoil. The latter thus yields no more and the desired firm surface which can be driven on is produced. <IMAGE>

Title: Castor for carts such as shopping trolleys or the like
IPC: B60B33/00
Filed: 1981-07-21
Abstract: In the case of a castor for carts, such as shopping trolleys or the like, there are two annular running-wheel discs which can rotate independently of one another and are provided with in each case one flange penetrating into the grooves of a conveyor belt. Arranged between the running-wheel discs is a braking element which is designed as a ring and surrounds, with radial clearance, a locking ring which is arranged coaxially with respect to the running-wheel discs and is connected in a rotationally fixed manner to the castor bearing body. To immobilise the castor, with the flanges penetrating into the grooves in the conveyor belt, the braking element overcomes the radial clearance and enters into locking connection with the locking ring. To prevent the running-wheel discs from expanding and to form a stable constructional unit, the running-wheel discs are acted upon in their regions adjacent to the flanges by axial support bodies which prevent an expansion.

Abstract: A typewriter has a keyboard (12) with a tabulator setting key (22), a tabulator deletion key (24) and a tabulator actuating key (26). By actuating the tabulator setting key, stop positions of the carriage (18) in relation to the printing cylinder (14) are memorised. By pressing the tabulator actuating key down slightly, the carriage is caused to make a forward movement up to the next tabulator stop position. By pressing the tabulator actuating key down to a first depth, a tabulator return mode is set, in which the carriage is moved backwards into the next preceding tabulator stop position and in which the printing cylinder is rotated by one line step so that the daisywheel (16) writes one line lower on the paper. As a result, the typing of the next line in a single column of the table is facilitated without the carriage return movement and the forward movement of the carriage to the beginning of the line being influenced. Each subsequent time the tabulator actuating key is pressed down slightly, the carriage is caused to make a backward movement to the next preceding tabulator stop position without switching the printing cylinder on to the next line. As a result, the typing of the next line when typing a plurality of columns within the table is facilitated without the carriage return and forward movements of the carriage being influenced.
