Title: Stocking tights - prod by carrying out a longitudinal cut in a hose-shaped piece of material
Inventor: MAZZI ARAMIS
IPC: D04B35/34
Filed: 1969-07-30
Abstract: Mesh or meshes formed by the same needle are caught by a hook shaped device and removed with this from the piece of fabric and cut through in a zone which is removed from the mesh forming zone. This process is carried out at least once at each revolution and is repeated for a number of revolutions or a number of rows of meshes, so that a longitudinal cut of the length desired is obtained. Hose-shaped piece of fabric can be of such a length that it forms a pair of tights which is closed or reduced at both ends to a point so as to form the foot. Advantageously a run-proof strip is formed along and about the longitudinal cut in order to form a reinforcement strip as edging for the opening corresponding to the wearer's waist. Use relates to any kind of pieces of fabric, but in particular to the manufacture of tights.

Title: Automatically controlled material buffer bunker - has buffer chamber with conveyor and inlet common to transfer hopper
Inventor: HOECHST UWE
IPC: B65G47/51
Filed: 1973-10-09
Abstract: The bunker is designed to even out the flow of material and retain it as necessary, being equipped with a reversible conveyor belt. It incorporates a transfer hopper, and alongside the hopper a buffer chamber with a common inlet, but clear of the discharge parabola of a filler conveyor. Below the buffer chamber and separated from it by a shutter is an unloading pocket. The bunker conveyor belt extracts material from the buffer chamber and discharges it into the pocket. The bunker can be so arranged that as material piles up in the hopper it runs down across the shutter and onto the bunker conveyor belt, which then stores it until the hopper is empty. This belt then discharges the material into the pocket after the shutter has opened and the discharge conveyor resumes working.

Title: Human heartbeat sensor - photoelectrically measures changes in light transmission of body part dependent on blood flow
Inventor: KLAUSSNER ALBERT
IPC: A61B5/024
Filed: 1973-12-21
Abstract: Human heartbeat sensor uses photoelectric sensing of the change oflight transmissibility of a body part in dependence on blood flow through it. Preferably, the periodic and individual alterations in the course of the photoelectric output signal are extracted by conventional electronic e.g. frequency filters. More particularly, this gives an indirect method for medical diagnosis by a simple procedure, which is more accurate than sensing of pressure and does not require undressing the patient since the measurement can be taken at a normally uncovered part, e.g. finger, ear, or any other thin organ. The light source is preferably infrared or of a reddish colour. The body organ is placed between this source and the photoelectric receiver which converts the intensity of light to an electrical potential or current.
