Title: Function generator with nonlinear output - uses resistive potential divider chains and logic gates for response curve adjustment
Inventor: HOLWECK PETER DIPL ING
IPC: G06G7/28
Filed: 1976-05-03
Abstract: The function generator with non-linear output consists of a series chain of resistors across which is a potential corresp. to the dynamic range of the generator input voltage. This potential is also across a chain of parallel-connected potentiometers. The junction of each resistor, corresponding to X-axis ordinates, is connected to controlled switches and to comparator inputs. The comparator outputs are connected via exclusive-OR gates for further switches connected to the potentiometer wipers. Both groups of switch circuits are connected to differential amplifiers whose outputs are multiplied. The product is added to a voltage corresp. to the start point of the X-axis increment. The sum voltage is the generator output for that particular input voltage.

Title: Digital drum counter display - feeds interrogation signal to additional electromagnet clutch to operate output transmitter contact springs reducing drive torque
Inventor: BOLSINGER ALOIS
IPC: G06M1/276
Filed: 1976-05-07
Abstract: The drum roller counter with pulse transmitter consists of an electro-magnetically driven counter (23), operating an escapement (26) and gearing (28), which rotates the individual display drums (3) providing a digital read-out. In order to reduce the drive torque, the contact springs in the output transmitter (12), are operated only when a read-out signal is required. This is effected by an interrogation signal to an additional electro-magnet clutch mechanism (9). The magnet operating arm (7) moves a hinged bridge (6) in which are mounted cam wheels (4) driven from the display drums. When the bridge is moved upwards, the cams can then engage the contact springs mounted on a printed circuit board (16) above the rollers. The contacts may be arranged to provide a binary-coded-decimal output for data transmission purposes.

Title: Washing machine water damage protection equipment - has enclosing sealing hose preventing leakage from main one inside and maintaining supply
Inventor: KLEIN HARTMUT
IPC: F17D5/04
Filed: 1976-08-04
Abstract: The protection equipment is particularly against water leakage from hoses supplying washing machines. The actual water hose is enclosed by a protective hose forming a watertight seal. In the event of leakage from water hose, this prevents escape of water, and takes over the function of delivery of it to the using machine, so that this can keep working. The intervening space between the two hoses can be connected to an indicator such as a pressure gauge, inflatable envelope ets., by a further hose or capillary tube, so as to give warning of water hose leakage. Damage to the latter can be indicated by a chemical or physical reaction e.g. alteration in the colour of a material.

Title: Spectrographic fuel calorific value measurement - is performed with fuel in gaseous state and detects emissions of several fuel components
Inventor: DEWEY C FORBES
IPC: G01N21/35
Filed: 1976-08-09
Abstract: Spectra (80, 90, 92, 94) of fuel components overlap in at least one area. The method is performed in a series of steps and involves measurement of the part of radiation energy absorbed by such fuel in a spectral zone in which spectra of the two or several components overlap. The energy absorption is a known function of the combined contribution of the components to the calorific value in the above overlapping spectral area. The relative concentration of other components which contribute to the fuel calorific value is measured. Their concentration is proportional to its contribution to the calorific value, so that the contribution to the calorific value by other components is determined. The calorific values from these measurements are combined.

Title: Wet dust separator efficiency improved by stabilising flow - to give uniform velocity profile across entire gas stream
Inventor: HESSE HANS-PETER DIPL ING
IPC: B01D47/10
Filed: 1976-11-20
Abstract: Method of increasing the sepn. efficiency of a wet dust separator, in which the gas is supplied by a blower through a diffuser into the sepn. zone where water is sprayed in and the wet particles are centrifuged is as follows. Flow-equalising device is incorporated between the blower and the diffuser, to ensure that a fairly uniform speed of the gas exists across the entire cross-section. The velocity profile across the cross-section of the flow may be a straight line or may be higher adjacent to the walls of the duct. More specifically, the quantity of water sprayed into the air is 2-4 (3) litre/m3 gas or air. Used for any industrial dust separator operating on the spray principle. By achieving a uniform velocity profile across the cross-section, it is possible coniserably to increase the quantity of water which can be effectively sprayed into the gas or air. cf. normal type of plant, where no increase in sepn. efficiency is obtd. with water quantities exceeding 1 litre/m3 gas.

Title: Soft soldering alloy - based on tin, lead and silver contains in addition zinc and/or cadmium
Inventor: MENGELBERG HANS-DIETER DR RER
IPC: B23K35/26
Filed: 1977-07-22
Abstract: The soldering alloy of Sn-Pb-Ag(0-4%), or Pb-Sn-Ag (0-4%) type contains in addn. 0.5-4 wt.% (0.6-2 wt.%) Zn and/or Cd. Suitable for soldering electrical components which are coated with a noble metal. Pref. compsn. is 56.8-63.2 wt.% Sn, 36.0-40.0 wt.% Pb, 0-2.0 wt.% Ag, 0.8-1.2 wt.% Zn. The alloy does not dissolve the noble metal component of the substrate, and provides a soldered joint of higher strength. The presence of 0.6-2 wt.% pref. 0.8-1.2 wt.% Zn and/or Cd improves the soldering properties and prevents a dissoln. of, e.g., Ag and Pd of the coating. The soldered joint remains ductile. The alloy is suitable for soldering ceramic substrates having a thin coating of a noble metal alloy. Dissoln. of the noble metal is prevented by the formation of an intermetallic Zn or Cd noble metal phase. Contents over 4 wt.% of Zn or Cd are no longer beneficial as the alloy exhibits inferior flow characteristics and the solder produces defective structures.

Title: Frequency diversity pulsed radar with high detection probability - has at least two one-bit quantisers in separate channels with outputs connected to OR=gate preceding extractor
Inventor: LUDLOFF ALBRECHT ING GRAD
IPC: G01S7/42
Filed: 1977-08-16
Abstract: The diversity radar system consists of two frequency channels (A, B) connected to single-bit quantisers (1, 2). The outputs are combined in an OR-gate (3). The output signal of this is passed to a target extractor, which in this case is a travelling window detector. Unlike the conventional form of additive combination where the detection probability is low due to the signal/noise ration of one channel affecting that of the other, the digital target extraction method does not suffer from this defect. If the signal is absent in one channel, this does not reduce the signal/noise ratio of the other since the threshold level is not exceeded from the point of view of noise spikes. A detection probability of 82% is claimed.

Title: Nonlinearity compensation system for transmission element - uses pre-distortion mixer with two diodes at input for intermediate frequency
Inventor: WEBER HERBERT
IPC: H03D9/06
Filed: 1977-09-27
Abstract: The method is intended for radio link systems, and the compensation is carried out by a predistortion mixer with an oscillator input. There is an h.f. output and a further input for the i.f. signal carrying the useful signal, to which the two diodes of opposite polarities are connected. The nominal h.f. level at one diode is higher than at the other, and interference level is applied to the diodes inversely proportional to the nominal h.f. level. Level and phase of the oscillator signal are adjustable at the other diode. The h.f. nominal level at the diode with smaller nonlinearity is greater than at the other diode with greater nonlinearity. Increase of the nonlinearity is achieved by reduction of the oscillator power. After difference formation a negative interference element appears. Its phase and magnitude is adjusted by adjustment of the oscillator level phase and magnitude at one of the diodes.
