Title: Controllable voltage to current converter e.g. for controllable filter - has input stage formed by differential amplifier with fixed steepness or presettable control
Inventor: FRIESEN LEO DIPL ING
IPC: G05F1/56
Filed: 1991-05-08
Abstract: The converter has an input stage (1) for receiving an input voltage (UIN), and an output stage (2), delivering the output current (IA). The input stage is formed as a differential amplifier stage with a fixed steepness or preset energising. A control current part (3) processes an external input current (IE). From each input current is formed at least one control current (ISt). The control current is used for variation of the output current of the output stage coupled to the control current part. Pref. the output stage has at least one current mirror, to which the control currents from the control current part are supplied. Thus the output stage output is energised, while the current mirror ratio can be varied by the control currents to affect the output current. USE/ADVANTAGE - For amplifier or filter circuit with wide control range.

Patent DE-4128706-A1 (DE)
Title: Coil hardness measuring method for paper or cardboard winding machines - involving measuring changes in coil dia. and length of material, deriving packing density using formula, low-pass filtering to eliminate vibration effects
Inventor: SOBOTTA CHRISTOPH
IPC: G01B21/02
Filed: 1991-08-29
Abstract: The method involves using the packing density of the coil as a measure of the hardness. The diameter of the coil is directly measured in steps from the displacement of the roller centre. The packing density is derived from the difference of the squares of the diameter (D1,D2) multiplied by pi and divided by 4 times the measured change in the length of the rolled material. High frequency disturbances of the diameter measurement caused by vibration of the coil centre are eliminated using a low-pass filter. ADVANTAGE - Coil hardness is determined using simpler and more reliable sensors.

Title: Appts. to produce two stiffened edges on thermo-formed plastic trays - has trays singly from stage, folds over longitudinal edges and feeds flat strip into fold at same time, heats and finally cools assembly
Inventor: ZITZMANN HANS
IPC: B29C53/04
Filed: 1992-05-19
Abstract: Appts. produces a folded-over holding strip at each side of a transparent moulded plastic tray so that it can be fitted over the edges of a rigid sheet. The appts. has a folding device fed singly with the moulded trays taken from a stack to a reciprocating feeder tool which is suitably shaped and is moved along a straight path; on each side of the path of the moving tool there is a folding rail to engage and turn over the outer edges of the cover; the next part is heated by heating cartridges in guides which wrap over the folded strips formed; similarly the next part guides and cools the material; finally the products are fed to a stacking and/or packing station. Thermoformed trays (10,11) are taken off a stack one at a time and moved into the layout in Fig. 5 by an endless belt type of device. Here the edge strips (13) of the trays move into tracks (20) which fold them ober. At the same time flat strips (22) are also fed in. The total effect is to continuously produce series of trays with edges formed by the original tray edges (14), wrap-over folds (15) and covering strips (16). The appts. then passes through guides in a heating station, where it is consolidated; finally it is passed through correspg. cooling guide guides. ADVANTAGE - The equipment can produce consumer packs at a high output rate (blister type packs). It is fully automatic and needs minimal supervision. It lends itself to a number of useful variations.

Title: Commodity track movement monitor - includes incremental path sensor for applying correction for track speed to switching frequency of switched capacitor low=pass filter to be in fixed relationship of up to one half of A=D converter sampling frequency
Inventor: BRAEU JUERGEN
IPC: G01D5/24
Filed: 1992-07-30
Abstract: A sensor (1) such as a differential field plate for detecting e.g. metal code markings on the moving track, or optical, capacitive inductive or ultrasound detectors, delivers an analog signal via an anti-aliasing filter (3) to a digitiser (2). The upper cut-off frequency of the filter is set by the frequency of switching (f0) of its capacitors by a converter (5) of the pulse repetition rate of an incremental detector (4) which establishes the sampling frequency (f1) for A/D conversion. The low-pass filter cuts off at a fixed fraction (max. one-half) of the sampling frequency. ADVANTAGE - Analog to digital conversion of detection signal for digital processing is adjusted for speed so that signal-sampling instant is related to distance travelled.

Title: Air intake system of an internal combustion engine
Inventor: RUTSCHMANN ERWIN DIPL ING
IPC: F02B27/02
Filed: 1993-05-07
Abstract: The air intake system of a double-bank internal combustion engine has one resonance vessel per cylinder bank and a further vessel arranged centrally thereto.
