Patent DE-2334041-A1 (DE)
Title: Surface finishing wire, bars, and rods - by removal of surface imperfections followed by sizing and polishing
Inventor: CUCUZ RANKO
IPC: B21C43/02
Filed: 1973-07-04
Abstract: The workpiece is initially sprayed with lubricant pref. graphite after an initial straightening operation then heated to >250 degrees F to remove the lubricant carrier ie. water or inert material medium, before passing through a lead die for sizing and working purposes. The workpiece then passes through a cutting or shaving tool to remove seams, laps, slivers, and decarburisation zones. A further lubricant coating is applied before the workpiece is passed through a finish die to size and polish the surface. Method is applicable to workpieces of strain hardened hot rolled carbon or alloy steels, tool steels etc. Improved cutting stability and uniformity are obtained together with improved surface finish with closer tolerances and minimum scrap.

Title: Fluidic oscillator with crystal registering frequency - in which oscillation crystal seals one outlet of the oscillator
Inventor: HOUBEN HEINZ DR ING
IPC: F15C1/22
Filed: 1974-07-13
Abstract: The fluidic oscillator has an arrangement for using it to determine the mixture ratio of gases by measuring the sound velocity of the gas mixture by means of the oscillator frequency. The oscillation crystal (15) closes one outlet (10) of the oscillator, which itself is connected to the inside of the space containing the gas mixture through a diffuser (6). This leads to two external return (11, 12) and two main channels (9, 10) one of which is connected to a suction pump (14) while the other, containing the oscillation crystal, leads through a preamplifier (16) to control equipment (18). An oscillation frequency dependent on the length of the return channels and the signal propagation velocity is generated, the oscillation frequency being an expression of the density of the gas flowing into the oscillator.

Title: Altering amplification of radar receiver - using amplifier damper altered by output voltage of control generator
Inventor: SCHLICHT HEINRICH DIPL ING
IPC: G01S7/34
Filed: 1974-07-20
Abstract: The invention relates to impulse or CW-radar receivers and provides a means of altering the amplification of the receiver in proportion to a predetermined function e.g. the STC-function of the amplification. The circuit incorporates, between the outlet of a control voltage generator (4) and the control inlet of an attenuator (3) switched into the receiver's amplification features, a linearising network (5). This ensures linear dependency of the alteration in attenuation on the output voltage of the generator. The network may have a voltage addition section on its input side to add a preselected constant direct voltage, with possibly a voltage limiter between them to ensure that the STC-function does not fall short of a minimal attenuation.

Title: Signal transmission esp. wideband communication system - has repeaters with signal generators and fault location device
Inventor: LOIDILLER MANFRED DIPL ING
IPC: H04B17/40
Filed: 1974-09-04
Abstract: The communication signal transmission system comprises a number of repeaters with signal generators connected to them. When a repeater is operative, it responds to a location signal consisting of an h.f. carrier signal modulated with an l.f. signal, and delivers to the network a characteristic for the repeater signal frequency. An evaluating device selectively indicates location signals from the repeaters. The network is divided in line sections with repeaters connected in series, whose signal generators deliver a signal whose carrier frequency is characteristic for repeaters in one line section, and is modulated by an l.f. frequency characteristic for each receiver within the section.

Title: Optimizing adaptive control system - for textile machines readjusts optimum production speed regularly to suit changes of system parameters
Inventor: VAS LASZLO
IPC: G05B13/04
Filed: 1975-02-25
Abstract: An optimising adaptive control system for the prodn. speed of textile machinery determines the optimum speed based on data acquired from the prodn. process and from a programme which defines the desired target. This speed is automatically maintained within certain limits. If the expected value of one or of all system parameter changes, the optimum prodn. speed is automatically readjusted to suit. The optimum is reassessed for periods less than several shifts so that the extra prodn. and lower costs result in more profitable prodn. The recording of all information provides valuable data about prodn. quality and maintenance. The system speeds up the introduction of new processes and/or materials.

Inventor: POESOLD ALOIS
IPC: A63C9/00
Filed: 1975-02-28
Abstract: The ankle lever catch strap for skis is made in two parts. On one end of the catch strap (1) is riveted a convex base plate on which is fixed at right angles a cylindrical catch-piece (5) with a conical leading end (8) on whose base is an angled shoulder (9) leading to a narrow holder (10). The second strap (2) has a housing (21, 22) in which are located two parallel spring rods welded together at one end (15) and located by means of the two housing-fixing screws. The cylindrical catch piece (5) is pushed through the hole (23) in the housing so that it passes between the spring rods so that the rods locate in the narrow portion of the catch-piece behind the shoulder (9). The catch is opened by pulling the catch out of the spring housing aided by the angled surface behind the shoulder. The spring rods can be replaced by spring plates, each having a round notch in the centre to catch behind the catch-piece shoulder.
