Title: Fabric treatment process - uses a foamed preparation contg. active component and wetting agent, applied to material surface by jet
Inventor: WALTER ANDREW TAINTER
IPC: D06M23/06
Filed: 1977-05-16
Abstract: In a treatment process to apply a prepn. to a porous substrate, such as a fabric, the prepn. is foamed to give a froth with a density of 0.005-0.3 g/cm3, and the foam is passed to an applicator jet. The substrate is passed continuously over and in contact with the applicator jet so that the foamed prepn. and the jet are moved together and the machine contact time is equal to or less than the equilibrium contact time. A present and controlled volume of foamed matter is applied to the surface of the substrate by the application jet to give the treated fabric. The treatment prepn. is composed of 5-75 wt.% a functional chemical, 0.2-5 wt.% foaming agent and 0-5 wt.% wetting agent. The remainder is water. The process can be used to treat fabrics, non-woven fabrics, paper or wood veneers. It can apply a flame retardant, a waterproof or water resistant cladding, a latex, a fabric softener, a lubricant, a hand builder, a dye or pigment, a lightener or bleach, a bonding agent or a scouring agent. The process is more economical as water extraction and drying are reduced so that less energy is required to finish the treatment process.

Title: Voltmeter based on liq. crystal display transducer - has no moving parts and gives an analogue display by using photodetector pair to generate linear voltage gradient
Inventor: JAEGER HANS DIPL PHYS DR
IPC: G01R13/40
Filed: 1977-05-28
Abstract: The voltmeter is without moving parts and consists of a flat rectangular liquid crystal display element to which the voltage concerned is applied and which displays clear and opaque sections of which the relative sizes indicate the applied voltage. A flat rectangular liquid crystal is mounted between a pair of deposited thin film electrodes (1, 2) to one of which (1) the voltage to be measured is applied. The second electrode (2) is fed at one end with the critical voltage of the liquid crystal, controlled by a small local control circuit contg. an LED (6) and photodetector pair (4, 5), and is designed to generate a linear voltage gradient between this point and the remote end of the electrode (2) which is earthed. The effect of this is that a section of the crystal becomes clear, the length of this section being a measure of the applied voltage, and a scale is provided for measurement of this length.
Patent DE-2730236-A1 (DE)
Title: Human body proximity detector for display window - has capacitative pick=up with threshold detector to illuminate lamp
IPC: G01V3/10
Filed: 1977-07-05
Abstract: An aerial consisting of a coiled length of wire (2) is stretched alongside a display window (1). Low frequency steep-sided spikes are generated by a pulse generator at a frequency of less than 10KHz and pass by way of an amplifier (4) to the aerial. The aerial signal and generator output signal pass to a comparator (8) which gives a DC output dependent on the difference in levels. A threshold comparator (9) measures this output against a level preset by a resistor (11). The threshold comparator (9) controls a relay (13) which switches on a lamp (14). A passer-by in the vicinity of the aerial affects its capacitance thus changing the signal level and causing the lamp to be illuminated.

Title: Fuel injection pump for IC engine - has pivotal centrifugal weight urging axially moving member to move thus adjusting size of orifice
Inventor: DRORI MOSHE
IPC: F02D1/04
Filed: 1977-09-24
Abstract: The fuel injection pumping appts. for supplying fuel to an internal combustion engine comprises an injection pump, a feed pump for supplying fuel under pressure to the injection pump, an axially movable member disposed in a surrounding body. An adjustable orifice is defined by the member and body. The size of the orifice determines the amt. of fuel supplied to the engine at each injection stroke by the injection pump. A pivotal centrifugal weight acts on one end of the member and urges the member in an axial direction to reduce the size of the orifice. A governor spring acts to urge the member against the action of the weight operator, adjustable means for varying the force exerted by the spring. The weight, spring and orifice together constitute a governor to control the speed of the associated engine accordance with the setting of the operator adjustable means. Resilient means acts to urge the reaction member and pivot in opposition to the governor spring, and a dash-pot acts to limit the rate of movement of the reaction member against the action of the resilient means when the force exerted by the governor spring is increased. A value controlled passage is in communication with the chamber of the dash-pot through which liquid can enter the dash-pot chamber at a substantially unrestricted rate.

Title: Multichannel optical film track - uses single sound track by separately modulating red, green and blue components of white light
Inventor: YAZAWA JUNICHI
IPC: G03B31/02
Filed: 1977-12-07
Abstract: A method incorporates three audio channels on an optical sound track of a film by modulating the red, green and blue components of white light separately. For replay, white light is directed through the film sound track and the three colours filtered out and separately amplified. Sound input (32, 33, 34) is amplified (36, 37, 38) in separate channels and each input to a modulator (39, 41, 42) operating on either red (43) green (44) or blue (46) light. The three colours are combined using mirrors (47, 48, 51, 52) for exposure of the film (49) sound track (49a). Replay is the reverse procedure using separate demodulators for the three colours.

Title: Capacitive switch system for domestic appliance - has sequentially actuated switch conductors coupled to charge rate detector comparing capacitance to reference
Inventor: HUNTS BARNEY D
IPC: H03M11/20
Filed: 1978-07-19
Abstract: Capacitive swtiches, which are actuated by the touch of an user, are coupled to unique pairs of conductors. The conductors are sequentially actuated, or interrogated, and simultaneously coupled to a charge rate detector that compares the capacitance associated with each conductor to a reference capacitor.
