PURPOSE:To prevent the position where a spike is attached from undergoing cracking and to prevent the spike from coming off, by fitting an embedding piece, in which a spike is embedded integrally, in an attaching hole in a tread thereby the spike is firmly mounted without being strained. CONSTITUTION:An unvulcanized substance or uncrosslinked high molecular substance is cast in a recess in a mold ...

PHD. 77-023 8.3.78 The invention enables the density distribution in a plane, in particular in a planar slice of a body, to be reproduced with the aid of scattered radiation. A narrow X-ray beam is then passed through the body to be examined. The scattered radiation produced in the path of said primary beam through the body reaches an array of detectors through a slot diaphragm which is disposed o...

Method and device for joining together an upper and a lower thread, which includes moving at least one first thread feeder from a thread pick-up position to a thread transfer position, inserting the upper and the lower threads into a longitudinal slot formed in a chamber, holding the threads in the slot until compressed air is admitted to the chamber, and at given positions during the movement of ...

A self-contained microsurgical laser which has a housing adapted for mounting on a surgical microscope. Mounted within the housing are an infrared laser source and a visible laser source. Means are provided in the beam path of the infrared laser for interrupting the beam and for polarizing and attenuattng the beam. Beam expanding means are provided in the beam paths. Wave front correction means ar...

The liquid-tight and air-tight covering (10) consisting of a plastic film and intended, in particular, for mattresses of hospital beds has lateral parts (16) formed from three film layers (22, 23, 24). The inner and middle foil layers (22, 23) are provided with air passage openings (22', 23'). For purification of the air flowing in and out, for example, from aerosols, bacteria and the like, filter...

The invention relates to a ski binding part, having rollers supporting the toe region of a ski boot, preferably a ski binding part which has symmetrically arranged, two-armed sole-holders with at least one roller in each case, which sole-holders can be pivoted about axles which are fixed to the binding, are arranged perpendicular to the running surface, and rest in each case with one arm on the sk...

A ski release side clamping binding with hinged jaw members is described. In the binding there is provided a housing. In the interior of the housing there is movably mounted a pair of housing mounted plate members. To each of the housing mounted plate members there is pivotably attached a jaw member. Coupled to the jaw member is a resilient clamping member. The resilient clamping means is provided...
