  • Patent number: 5667504
    Abstract: A process and an apparatus for adjustment of a switchable, flow-limiting device for limited flow of liquids or gases employs a remote service device. The flow-limiting device and the service device are spatially separated and there is no bodily connection between the two. Energy necessary for adjustment of the flow-limiting device is transmitted from the service device into an infusion pump that contains the flow-limiting device. The flow-limiting device is a valve having three stable operating positional states. The valve can only be switched while energy is being transmitted from the service device.

  • Patent number: 5297589
    Abstract: In a heddle frame with detachable corner connections each heddle support has a horizontal projection extending into a cavity of the frame stave and is clamped in place with the use of set screws. The frame stave is constructed of stable longitudinal bands and very thin side walls interconnected as by welding. A rigid insert is inserted at opposite ends of the hollow frame stave, the insert comprising spaced, parallel and longitudinal extending support blocks lying parallel to the longitudinal bands of the frame stave, and reinforcing walls connected to the support blocks, the walls having a wall thickness about 3 to 6 times greater than that of the thin side walls of the frame stave.

  • Patent number: 5183082
    Abstract: A frame stave includes a supporting bar designed as hollow body and adjoined by a supporting member for the heddle carrying rod. The supporting bar reaches its bending strength by a massive longitudinal bar of a substantially square cross-section which forms one of the narrow sides. The other narrow side is formed by the leg of an angeled supporting member for the heddle carrying rod. Two extremely thin walled sheet metal members are mounted preferably by a laser welding to the longitudinal bar and the leg and form the two broad sides. A filler body is located in the hollow inner space of the supporting bar which is for instance of a honey-comb like structure in which a plurality of individual hollow spaces or chambers are formed, which are filled by a sound attenuating material which remains elastic. Strips of material which are impregnated by a bonding agent close the filler body off at both sides and are bonded to the sheet metal parts.

  • Patent number: 4390045
    Abstract: A heddle frame stave for heddle frames includes a light metal hollow construction having, at least on one side wall, and preferably on opposing side walls, a flat groove-shaped recess. A flat steel strip is adhesively secured in the recess, the strip having a thickness of less than half the side wall thickness and covering preferably at least 60% of the surface of the side wall of the hollow stave. Vibration dampening of the heddle frame stave is thereby achieved, so that the sound produced due to vibrations and the noise development associated therewith, will be reduced considerably especially for fast running weaving machines.
