Patent NL-9001816-A (NL)
IPC: H03D3/00
Filed: 1990-08-13
Abstract: A subscriber unit for wireless communication with a base station in a wireless subscriber communication system includes a FIR chip, a DIF (digital intermediate frequency) chip, a single processor chip and a radio. The processor chip transcodes a digital voice input signal to provide digital input symbols; demodulates an output signal received from the base station to provide digital output symbols; and synthesizes a digital voice output signal from the digital output symbols. The FIR chip FIR filters the digital input symbols and generates timing signals for timing the transcoding and synthesizing operations in the processor chip. The DIF chip digitally synthesizes a digital intermediate frequency signal by direct digital synthesis (DDS) and modulates the digital intermediate frequency signal with the filtered input symbols to provide a modulated intermediate frequency input signal. The radio further processes the modulated input signal for transmission to the base station.

Title: Process for the manufacture of a hollow needle to stitch labels and the like on fabrics
IPC: B21G1/08
Filed: 1981-06-09
Abstract: A method of manufacturing hollow needles from round metal blanks in order to form a needle which has an inner front portion with a front end tapering to a point and a rear portion having a larger diameter than the front portion and forming a mounting shank, comprising forming a longitudinally extending needle guide to the needle such that the guide is open at the rear end of the mounting shank and tapers from a substantially uniform depth along a major portion of its length to a minimum depth adjacent the tip. The channel is of a shape to receive substantially cylindrical cross pins having an appended piece of filament which form a part of fasteners for tags, buttons and similar items to be attached to carrier materials such as textiles. The method is carried out by the use of a disc-shaped miller cutter which has U-shaped convex teeth for milling the central area of the channel in side tooth portions for milling shoulders on each side of the channel which are of lesser depth than the channel. The side tooth portions are employed to mill inclined V-recessed surfaces on each side of the central channel. In accordance with the inventive method after the channel is milled it goes to extend from the rear end along the inner front portion and taper to substantially a minimum depth at a spaced location from the tip, a stamping tool is used to engage into the inclined surfaces formed by the side teeth so that these surfaces are pressed inwardly to close a major portion of the length of the channel but without closing a release portion adjacent the tip of the needle which is less substantially equal to the width of the channel.
