    • An apparatus for performing lamellar refractive corneal surgery includes a base ring adapted for seating on the sclera of the eye to be operated upon. A planar plate is fixedly attached to this base ring so that the mutually adjacent surfaces of the plate and the base ring conjointly define an air gap. As oscillating knife is guided in this air gap during the cutting process and is moved in a guide connected to the base ring. The surface of the planar plate facing the eye contains an applanate surface which is preferably defined by the end face of an insert inserted into the planar plate. A ring-shaped recess open toward the eye concentrically surrounds the insert and communicates with a conduit to which a partial vacuum can be applied.
    • 用于执行层状折射角膜手术的装置包括适于放置在要被操作的眼睛的巩膜上的基座环。 平板固定地连接到该基环上,使得板和基环的相互相邻的表面共同限定气隙。 由于在切割过程中摆动刀在该气隙中引导,并且在连接到基座的引导件中移动。 面对眼睛的平面板的表面包含一个凸起表面,该表面优选由插入到平板中的插入件的端面限定。 朝向眼睛开放的环形凹部同心地围绕插入件并与可以施加部分真空的导管连通。

    • The invention relates to an axle suspension means for motor vehicles, wherein the guide means of a rigid axle is constructed so that the latter changes its position in the sense of a positive oblique springing during inward spring stroke movements, and executes no inherent steering movements during one-sided and alternate-side inward and outward spring strokes. For this purpose the rigid axle is guided on each side by a pair of guiding control arms which determine, for its wheel axis, a pivot axis about which the wheel axis is movable by means of a guide arm retained on the vehicle body in the sense of the positive oblique springing during inward spring stroke movements. Simultaneously, the two pairs of guiding control arms, each in common with a rocker arm mounted on the rigid axle pivotably about the pivot axis staggered vertically to its wheel axis, form straight guides guiding the pivot axis in a vertical plane during inward spring stroke movements, whereby inherent steering movements of the rigid axle are prevented.
    • 本发明涉及一种用于机动车辆的车轴悬挂装置,其中,刚性车桥的导向装置被构造成使得后轮在向内弹簧行程运动期间以正向倾斜弹簧的意义改变其位置,并且在内部弹簧冲程运动期间不执行固有的转向运动 单向和交替的向内和向外弹簧冲程。 为此,刚性轴通过一对引导控制臂在每一侧引导,该对引导控制臂为其轮轴线确定枢转轴线,围绕该枢转轴线可以通过保持在车身上的引导臂在该意义上移动 在向内弹簧冲程运动期间正向倾斜弹簧。 同时,两对引导控制臂,每一个与安装在刚性轴上的摇臂共同的枢转臂可绕枢转轴线枢转地垂直于其轮轴线交错,形成在内向弹簧冲程移动期间引导枢转轴线在垂直平面中的直线引导件 从而防止刚性轴的固有转向运动。

    • A partial lining disk brake with floating saddle for vehicles, particularly for motor vehicles, in which the floating saddle is constituted by an essentially plane frame that is arranged with its longitudinal webs secant-like with respect to the brake disk and which receives in one longitudinal web at least one brake cylinder and in another longitudinal web at least one abutment for the brake lining; the floating saddle is displaceably guided at the brake carrier axially parallel to the brake disk whereby the brake carrier is also constructed frame-like and, insofar as it has any supporting function, is arranged exclusively underneath the floating saddle, the floating saddle engages with downwardly extending projections in corresponding guide elements of the brake carrier to assure an accurate guidance thereof.
