Abstract: A shoe midsole for running shoes having spring/tread elements (2, 4, 4a), In order to achieve good damping and running support, it is proposed that a bow-shaped spring/tread element (2) is arranged on the underside in the forefoot region of the shoe midsole (1), which is fixed with a first end to the front end of the midsole (1) and with its other end to a first spring/tread element (4, 4a), of which the direction of movement is parallel to the extension of the midsole, so that it exerts a thrust force on the spring/tread element (2) when it springs out.

Abstract: A deflection element (10) for robot arms has two arm braces that are pivotally mounted on a joint mechanism. In order to create a universally useable deflection element, the two arm braces (12) are each mounted on a support structure (20) of the joint mechanism by means of an arm joint (18), and the two arms braces (12) are coupled to a connecting element (22) between the two arm joints (18), said connecting element (22) being movable relative to the support structure (20); furthermore, at least one actuating element (50; 51), which moves the connecting element (22) and thus pivots the arm braces (12) between the end positions thereof, is arranged between the support structure (20) and the connecting element (22).

Abstract: A control element (1310) has at least one elastic internal part (1332) that can be connected, via a connection, to a pressurized fluid source and/or a vacuum source, which permits pressurization or evacuation of a cavity in the internal part (1332). In order to provide a control member for general use, it is proposed that the elasticity module of a wall (1328) bounding the internal part (1332) is formed differently in certain sections such that, instead of a homogeneous increase or decrease in volume under pressurization or evacuation, an oriented change in shape takes place, between a resting state and a pressurized or evacuated state, that describes a control path of the control element (1310).

Abstract: The ski has a box-shaped, substantially rigid middle portion, a front portion and a rear portion which can be easily bent and are elastic and resilient in an upward direction and are capable of torsion in the longitudinal axis. Balancing elements formed of soft, but permanently elastic material, are inserted at the transition of the middle portion to the rear portion in the direction of the rear end of the ski, on the one hand, and/or at the transition of the middle portion to the front portion in the direction of the tip of the ski on the other hand. The balancing elements are inserted in the ski so as to be either not detachable or fixed, but detachable and exchangeable.

Abstract: A still projector with a magazine guide channel, a projection lens, and a manual electrical switch has a cover that encloses all these components and fits closely in a recess in the housing. The cover is preferably shaped to fit the external contour of the housing and has a first plate covering the projection lens and one end of the magazine channel, a second plate covering a switch and the other end of the magazine channel, and a panel extending between the two plates and covering the top of the magazine channel.
