Title: Test film for offset process - has different thickness lines with set gray level and spacing
Inventor: WERNER GERHARD
IPC: G03F5/00
Filed: 1979-02-10
Abstract: A test film for checking an offset process has a series of wide lines spaced by large amounts and narrower lines at closer spacings. The thick lines have a set gray level which is checked with a gray scale chart. The test film is inserted in different places on the document table for checking the operation of the machine.

The spaced lines can be replaced by a set of concentric rings and shapes more readily positioned in small areas of the document support.
Patent DE-2906054-A1 (DE)
Inventor: SUTTER FRANZ
IPC: A61B90/00
Filed: 1979-02-16
Abstract: During the operation of a broken-off condyle (1a) of a femur (1) a stepped blind hole (1d) is formed therein. The hole (1d) is formed with a device (13) having a first tool (15) formed by a hollow spiral drill and a second tool (17) formed by a hollow end-milling cutter which is fixed so as to be untwistable but axially adjustable on the first tool (15). The cutting part (15b) of the first tool (15) projects out of the thicker cutting part (17b) of the second tool (17). The latter is provided with a conical stop surface (17f) on that end of its cutting part (17b) which faces away from the front blades. On making a hole (1d) the stop surface (17f) comes to bear upon the femur (1) and thereby limits the hole depth (a) to a predetermined value which can be selected by adjusting the second tool relative to the first tool. <IMAGE>

Patent DE-2941481-A1 (DE)
Title: Frequency limiter for analog signals - suppresses components above upper frequency limit using digital processing
Inventor: BLUETHGEN BJOERN
IPC: H04B14/04
Filed: 1979-10-12
Abstract: The frequency limiter samples the analog signal (A1) and converts the samples into PCM words. The difference is formed between two consecutive PCM words. The difference PCM word contains an auxiliary bit and is passed to an evaluator (AW) with a polarity sequence discriminator (PFD). The discriminator replaces whichever is the average difference PCM word with a difference PCM word of the opposite polarity whenever two or more consecutive polarity changes occur. The oppositely poled difference PCM word is derived from the preceeding and subsequent difference PCM words. This modified difference PCM word is then converted back into the original analog signal (A2).

Title: Coanda effect multipurpose feed nozzle - uses helical fast flow of propellant fluid to draw medium by underpressure
Inventor: RAMMS WOLFGANG DIPL KFM DR
IPC: F02K7/12
Filed: 1979-12-03
Abstract: The fed medium passes at high speed through a tangential pipe (3) into a sleeve (2) above the base plate (8) and through a guide web (4) round a Venturi nozzle (1) in helical rotation. There it rises inside the sleeve. It is then deflected by the upturned edge (2a) onto the inside of the nozzle and flows through the throat (6) of the nozzle to the outlet opening (7). The underpressure hereby produced conveys the medium which is drawn in through an opening (5) through the throat of the nozzle and thus to the outlet opening.

Title: Timber beamed roof stiffening perforated metal strip - is introduced stretched and fastened for simple fitting
Inventor: KOPP WERNER
IPC: E04B7/00
Filed: 1980-02-15
Abstract: Strips of metal, with continuous hole configuration are used in wooden beam roof structures. They are used for stiffening the roof surface, and have to be stretched. A special process is used for stretching these strips, in which the strip is merely inserted, tightened and secured. It can be rapidly tightened and stretched to full 100 per cent capacity. The strip is then easily nailed in position over its whole length, to form part of a strong roof structure.
Patent DE-3014257-A1 (DE)
Title: Dust disposal from dry filters - by water jet ejector and sludge pump
Inventor: HOELTER HEINZ ING GRAD
IPC: E21F5/20
Filed: 1980-04-14
Abstract: Dry filters, esp. those used in underground mines and operating at a high negative pressure, are fitted with screw conveyors which move the collected dust into a shaft with a water jet ejector. This converts the dust into a slurry and conveys it to a sludge pump for disposal in a gate side or goaf pack without causing any dust nuisance. This also prevents the premature wear of the normally used star wheel extractors for the dry quartz-contg. dust, and the necessity of packing the dry dust into sealed containers.

Patent DE-3015141-A1 (DE)
Inventor: FLAMM PETER MICHAEL ING GRAD
IPC: H03M1/36
Filed: 1980-04-19
Abstract: The invention permits an n bit resolution to be achieved with an n-1 bit converter. In a color television receiver the analog-to-digital converter is a parallel analog-to-digital converter with p=2r-1 differential amplifiers as comparators, where r is the number of binary digits of the output signal of the analog-to-digital converter minus one. The composite color signal is then applied as the input signal to the noninverting (or inverting) inputs of all p differential amplifiers and the inverting (noninverting) inputs of the differential amplifiers being connected successively to the taps of a resistive voltage divider which contains equal-value resistors and is fed with a reference voltage (Ur). For the duration of every second line, either the reference voltage or the input signal is shifted by  DELTA U=0.5 Ur/2r.

Abstract: A recording system is provided for commutation faults in a mains rectifier. It has a recording circuit for the current that flows to the rectifier valve branch. There are comparator networks connected to the current recorders to prevent any damage to plant components when the current rectifier has tripped and supply a signal for the phase fault. The inputs of the comparator branches are connected to a synchronisation signal transmitter as well as to the current recording network. The synchronisation signal is derived from the mains voltage or a voltage in synchronism with the mains.

Title: Illuminated instrument knob esp. for automobile or aircraft - has peripheral symbols with thin contrast coating of e.g. ABS
Inventor: LINDEBORGH KNUD BJOERN
IPC: B41F19/06
Filed: 1980-05-20
Abstract: A method of making an indicator or operator knob, such as particularly a rotatable knob for a channel selector, consists of first making, from a translucent material, a knob optionally having radial incisions; then hot-embossing the projecting symbols around the rim of the knob; then partly covering the rim with an opaque plastics material. Pref. the dye applied during the hot-embossing is so thin that only a partial loss of light results and an optimum contrast effect is obtd. A preferred translucent material is acrylic, esp. having a fusion point of 200-230 deg.C. The opaque plastics material may be ABS, having a fusion point of 180- 220 deg.C. The knob can thus be illuminated from internally due to its translucent properties and is suitable for the dashboard of an automobile or an aircraft.

Title: Glow discharge process for coating e.g. with polymer or silicon - uses gas reservoir behind counter electrodes with large open perforated area
Inventor: PACHONIK HORST DIPL PHYS
IPC: C23C16/54
Filed: 1980-06-02
Abstract: Substrate coating process involves placing substrates (I) near an electrode, placing a counter-electrode (II) at a uniform distance from (I), changing gas (III) chemically by a capacitive glow discharge, passing (III) through holes in (II) and exhausting spent (III). The novel features are that (II) is so strongly perforated that (III) can diffuse through holes in both directions, a (III) reservoir bounded by (II) is provided and (III) is let into and sucked out of this reservoir. The process is specified for the prodn. of a glow polymer film from monomeric gas or an amorphous Si film from silane. It is suitable for coating a large amt. of (I) in series operation and frequent cleaning of deposits from (II) is avoided.

Title: Cooling water pump for vehicle engine - has curved blades made of bimetallic material to vary flow to match water temp.
Inventor: HOFBAUER PETER DIPL ING
IPC: F04D29/24
Filed: 1980-06-13
Abstract: The radial-flow pump for circulating cooling water around the circuit for cooling a vehicle engine has blades (5) which are curved in one direction to assist the water flow. These blades are made of bimetallic material and the part with the larger coefficient of expansion is on the convex side of the blades. The design ensures that the quantity of water conveyed by the blades varies with the changes of speed or loading of the engine. The curvature is controlled automatically by the temperature of the cooling water and/or the rotary speed of the pump.
