Abstract: ABSTRACT On a cart which is guided by a person not riding on it, it is common for the cart to be on two pairs of wheels, one pair of them on a fixed axle, and each wheel of the other pair on a short axle which swivels about a pivot, the axis of which is vertical and not on a line which intersects the axis of the wheel axle, and the bearing of which is fixed to the cart body. For carts which have to be guided with precision in both forward and reverse directions, such as lawnmowers, the usual swivel wheel is unsuitable because when the cart changes direction between forward and reverse the swivel wheels swivel through half a revolution, which causes difficulties when the lawnmower is alongside an obstacle such as a fence. It is necessary, in in any kind of swivel wheel for the vertical pivot to lead the wheel axle as the cart is moving, which means that the relative positions of the axle and pivot must be reversed as the cart changes between forward and reverse. In this invention the vertical pivot is allowed to slide along a guideway which depends from the wheel axle, in order to acheive the above mentioned reversal of positions. In the invention there is also a spring clutch arrangement which prevents the swivel wheel from rotating on its axle while the pivot is changing positions. Furthermore, each of the pair of swivel wheels may be linked to the other so that both always swivel by the same amount.

Abstract: CABINET LOCK WITH RECESSED HANDLE Abstract A cabinet lock has a housing that includes an elongate body.  An operating handle is mounted on the housing for pivotal movement about an axis that extends transverse to the length of the body.  The body slidably mounts 1) a latch bolt for linear movement along a path of travel that substantially parallels the axis of pivotal movement of the handle,  and  2)  an operating member  for  linear  movement  along  a  path  of  travel  that substantially parallels the length of the body.  The handle has a formation that drivingly engages the operating member for moving the operating member from a latched position to an unlatched position in response to pivotal movement of the handle from a nested position to an operating position.   A key cylinder is rotatable mounted on the housing and carries a stop formation that is operable 1)  when the key cylinder is in an unlocked position to permit sliding movement of the operating member along the body in response to movement of the operating handle from its nested to its operating position, and 2) when the key cylinder is in a  locked position  to  retain the  operating member  in  its latched position and to retain the handle in its nested position.          Interacting cam surfaces are provided on the slide bolt and on the operating member for causing the slide bolt to retract from its normally projected position in response to movement of the operating member from its latched to its unlatched position.  A compression coil spring is interposed between the slide bolt and the housing to bias the slide bolt toward its projected position.          The biasing action of  the  spring  is  transmitted through the interacting cam surfaces to the operating member for biasing the operating member toward its latched position,  and through the operating member to the handle for biasing the handle toward its nested position.

Abstract: "HYDRAULIC PISTON AND CYLINDER ARRANGEMENT IN WHICH THE OUTER WALL OF THE PISTON ROD IS FREE FROM FLUID"      ABSTRACT OF THE DISCLOSURE           A hydraulic  piston  and  cylinder  arrangement retains the outer surface of a sleeve forming the piston in dry condition.   The cylinder provides an outer wall and an inner stem with the sleeve sliding inwardly of the outer wall and outwardly of the stem.  A head on the end of the stem cooperates with the inner surface of the sleeve.  A bearing member on the end of the sleeve remote from the head cooperates with the outer surface of the stem.  A first chamber is thus defined between the head and a closure cap on the sleeve to provide an expansion chamber.  An annular chamber between the outer surface of the stem and the inner surface of the sleeve and closed by the bearing member provides a return chamber.   Two fluid channels coaxially arranged within the stem provide the communication of fluid to the chambers.

Abstract: ABSTRACT: Semiconductor device for producing an electron beam.              In a semiconductor cathode, the electron-emitting part of a pn junction (5) is provided in the tip of a projecting portion (10) of the semiconductor surface (2) which is situated within an opening 8 in an insulating layer (7) on which an acceleration electrode (9) is disposed. Due to the increased electric field near the tip, a reduction of the work function (Schottky effect) is obtained. As a result, cathodes can be realized in which a material (14) reducing the work function, such as caesium, may be either dispensed with or replaced, if required, by another material, which causes lower work function, but is less volatile. The field strength remains so low that no field emission occurs and serarate cathodes can be driven individually, which is favourable for applications in electron microscopy and electron lithography.
