Title: Carpet cleaning system with foam dispenser - uses two working steps for motor driven brush roller, one for foam application and another for rinsing water discharge
Inventor: VOIGT FRIEDER DR ING
IPC: A47L11/34
Filed: 1979-02-02
Abstract: The carpet cleaning process, using a foam applicator, is carried out in two working steps. In the first one, pressure air from a blower, included into the foam cleaner is supplied into cleaning liquid which can be foamed. The foamed liquid is supplied to a brush roller, driven by the blower motor, which provides the cleaning action over the carpet. The suction channel of the brush roller chamber, connected to the suction side of the blower, is closed by a change-over device during the application of the cleaning foam. Simultaneously, a suction port outside the brush roller chamber, is freed. In the second working step, the cleaning foam applied to the carpet is sucked away and fed into a retaining container. During this step the suction channel is opened by the change-over device and the suction port is closed. For thorough exhausting of the applied cleaning foam, the container of the cleaning liquid is filled with an appropriate rinsing liquid, which is then supplied to the brush roller for application to the carpet.

Title: Detection circuit for impulses on top of slowly changing voltage - has detection threshold which is function of base voltage magnitude (NL 22.10.80)
Inventor: MARINGER ALBERT ING GRAD
IPC: G01R29/027
Filed: 1979-04-20
Abstract: The input signal (E) to the detection circuit goes to both terminals of a differential comparator (V). The gain and offset at the positive terminal is determined by resistors (R3, R4, R5, R6) and the time response at the negative terminal is delayed by a resistor capacitor lag (R2, C1). The time constant of the resistor capacitor network is much faster than the expected rate of change of the incoming base signal so that only sudden impulses trigger the comparator. The size of the trigger threshold can vary according to the base voltage magnitude. Together with a similar negative detector, the circuit is suitable for monitoring the current in a solenoid valve.

Title: Extruded thermoplastic solar heat collector panel - with sectioned upper heat insulating and lower heat absorbing part
Inventor: ERB ROBERT ALLAN DR
IPC: F24S10/70
Filed: 1979-08-03
Abstract: A standardised extruded thermoplastic roof panel for use as a solar heat collector consists of an upper transparent area which is divided by a horizontal partition from the lower opaque part. The upper part is subdivided by ribs into rectangular or triangular spaces which are closed up at the ends to act as heat insulating area. The lower part is also subdivided by ribs into similar ducts which are jointed, however, at the ends to form a circulating system for a heat absorber fluid. This reduced convection currents and heat losses caused by them to a minimum. The panel design also minimises any flexural deformations of the panels.
Patent DE-2938947-A1 (DE)
Inventor: LECHNER ROBERT DIPL ING
IPC: H04Q11/04
Filed: 1979-09-26
Abstract: An analog-to-digital converter for converting analog signals received in parallel on a plurality of incoming lines into digital signals comprises a selector unit having a plurality of signal inputs. Each input is connected to an incoming line via a filter capacitor. A grounded network connected to an output of the selector unit has a storage capacitor and a switch arranged in parallel for short-circuiting the capacitor temporarily. The network simulates a common resistor for establishing a filter section together with the presently through-connected filter capacitor. One input of a comparator is connected to the selector output. The second input is supplied by an analog reference voltage source which may comprise a digital-to-analog converter for supplying an analog reference voltage adjustable under control of the current condition of the comparator output signal. The reference voltage thus is iteratively approximated to the current analog value of the stored sampling probe.

Patent DE-2950156-A1 (DE)
Title: Remote stereo amplifier adjustment system - uses sampling microphones in auditorium area
Inventor: FLIER GUSTAV ING GRAD
IPC: H03G3/32
Filed: 1979-12-13
Abstract: A small transmitter is placed into the auditorium area together with left-and right oriented microphones for receiving the sound output of the stereo loudsoeakers. A signal representing the ratio of the sound intensities from the two sound sources is being transmitted to a receiver unit which compares it with the ratio directly derived from the stereo channel source. If the comparator output were zero, no change is called for. If it is negative or positive, the amplification levels of the corresponding deficient left or right amplifier is increased until the true sound image is obtained within the auditorium. The transmitter is in operation for a few seconds only. A light signal indicating completion of the adjustment process may be employed. The adjustment system is used in situations where due to local acoustic conditions, the actual sound levels reaching the ears of a person from the left and right loudspeakers may be proportioned differently from that originally recorded on stereo tracks. Moreover, also the left and right amplifiers or loudspeaker units or transmission line characteristics may differ and thus falsify the acoustic impression, and the stereo effect suffers.

Title: Yarn tension monitor - has conical roller with yarn guides to position yarn according to tension
IPC: D02G1/02
Filed: 1980-04-05
Abstract: In the tension-free feed system for a synthetic yarn, partic. to a texturiser, there is a tension monitor (12) with a roller (1) rotated by the yarn (4) passing partially round its conical mantle, together with at least one counter roller (2,3). The yarn guide mechanism (6) moves the yarn level (4') along the conical roller (1) to correct any tension. In the path of yarn travel, there can be a heating section and a yarn advance in the stages of the texturising process, and each stage is fitted with a conical roller (1) with the yarn passing partially round. The tension monitor (12) for the heating stage is more lightly pretensed than the monitor for the false twister. The tension monitors are against each other for the yarn guide (6) to position the yarn (4) along the conical roller (1) according to the tension conditions in force. The system ensures that the yarn tension is under control and corrections can be made to compensate for any irregularities, and prevent capillary or structural yarn breakage.
Patent DE-3022866-A1 (DE)
Title: Speed monitoring of several separate but related drives - employing microprocessor for protection and alarm functions with speed-dependent input signals
Inventor: KLINKHAMMER KARL
IPC: H02P23/00
Filed: 1980-06-19
Abstract: The application is to individual motor drives which must operate in close speed relationship to one another. Each drive operates a relay (K1...K4) through which an impulse signal, speed-dependent, is passed to a microprocessor-based monitoring system (10,11,12). The relays have a common but exclusive supply source (13). Further relay inputs (K5,K6) give direction information. The microprocessor checks the various pulse counts over a given time in accordance with an established programme (2). If there is no significant error there is no output. Should an error arise the processor gives two output signals: one to an indicator (H1...H4), e.g a LED showing the defective drive, and the other to a trip relay (K7). The latter stops all the drives. A second processor, receiving the same input information, can be used in a control mode to regulate the speed of the individual drives.

Title: Pretreating plastics surfaces before coating - by bombardment with accelerated metal or mineral particles to improve bond
Inventor: MEYER MANFRED
IPC: B05D3/12
Filed: 1980-07-14
Abstract: Plastics surfaces are treated by blasting with accelerated, energy-charged metal or mineral particles to improve the bond of subsequent lacquers, dyes or adhesives to the surface. The jetting or bombardment may modify the structure of the surface, the particles becoming integrated into the surface in addition to the electrostatic charging of the surface. The method is intended as a replacement of chemical-thermal treatment and cleansing of surfaces and is simpler, less time- consuming and less energy-consuming.
Patent DE-3027960-A1 (DE)
Title: Control switching for spark erosion machining gap - uses parameters of pulse applied between workpiece and tool electrodes for defining machining gap
Inventor: JITIANU GHEORGHE DIPL ING
IPC: B23H7/18
Filed: 1980-07-24
Abstract: The adjustment of the working gap in spark erosion machining installations is controlled by defining the working gap, using parameters of each voltage pulse applied between the tool and workpiece electrodes. The parameters are the ignition time of the discharge and the voltage value between the electrodes during the current pulse. The parameters of one discharge to the next are stored. The parameters are summated, and a proportionality factor is allocated to each parameter. The sum represents the value to be held constant during the machininq process. The summation of the stored parameters is interrupted when a short circuit, or a light arc discharge, occurs in the working gap. The control circuit converts the ignition time values of discharges into voltage values. The voltage during the current pulse between the electrodes is measured and stored by a second circuit, incorporated into the control one.

Title: Silica coke oven lining brick - satd. with tar and protectively coated with quartz on side facing chamber
Inventor: SCHULTE EGON
IPC: C04B41/52
Filed: 1980-08-23
Abstract: Silica bricks for coke oven lining are protectively treated by first impregnating the bricks with a neutral or acid tar. At least the oven-facing side of the bricks is then either treated with a tar-solvent, e.g. CCl4, or tempered, and finally sealed with a quartz material compsn. Neutral or acid tar use prevents brick attack. Tar-solvent treatment or tempering improves adhesion of lining. The brick resists premature wear on charging the coke oven with flash pitch. C infiltration into brick is prevented.

Abstract: The protection device provides a short-circuit across the current lines, causing a line protection fuse (2) to be operated its impedance being adjusted via a series current limiting resistor (9), so that with a low network impedance the short-circuit switch is protected against false operation. However, with a high network impedance, the short-circuit current is rapidly attained. The series resistor (9) is able to handle the max. short-circuit current without being damaged. Pref. the device uses a thyristor or a triac (8) between the current lines triggered to provide a short-circuit if water penetrates the device. The device can be used on its own or to provide a back-up protection if a fault current switch fails.
