Title: Electrically-operated central heating shut=off valve - is operated by a heat-sensitive spring and heating element and has copper blocking cylinder
IPC: F16K31/02
Filed: 1983-09-14
Abstract: The heating shut-off valve can be operated electrically by a room thermostat, a computer or a central control panel, and is suitable for controlling the flow of heating water in large offices, auditoriums and other locations where heating is not continuously required. The body of the valve contains a sliding flow-blocking cylinder, moved by an elastic spiral spring. - The spring is constructed so that it extends when its temperature reaches a level between 60 and 70 deg.C., and opens the valve. If its temperature is less than 55 deg.C., the spring returns to its original form closing the valve. The spring is wound around a heat-conducting sleeve, which surrounds an electrical heating coil. Suitable materials for the blocking cylinder and valve body are copper or plastics.(0/4)

Abstract: Abstract of the Disclosure:        A refillable hand-operated liquid sprayer of the type which requires no container pressurizing gas nor other foreign propellant.  It operates to pump a small quantity of liquid to be sprayed from a container to small cylindrical chamber wherein the liquid is pressurized by the force of a coiled spring which is stressed during "cocking" stroke preparatory to spraying the liquid from the device.  A cover unit is removably mounted on the open end of the container, and a spray head is rotatably mounted on the cover unit, the rotation of the head relative to the unit causing the spring to be compressed thereby sucking liquid up from the container into the chamber.  A hollow stem made of rigid material such as metal or hard plastic is provided for communicating the chamber with a discharge valve and also serving as a guide for a piston which moves vertically within the cylindrical chamber.  With this arrangement, there is little likelihood that the stem is caught in the spring thereby hindering further compression of the spring or resulting ? severance of the stem. as is frequently the case with previous flexible hollow tube.

Abstract: IMPROVED DATA RETRIEVAL AND ERROR DETECTION CIRCUITRY FOR A WIDTH-MODULATED        BAR-CODE SCANNING APPARATUS                   Abstract of the Disclosure An apparatus for processing the signals that are generated when a width-modulated bar code is manually scanned includes a simplified serial arithmetic unit and an error-detection circuit which detects errors in scanning tech-nique as well as parity errors and the like.  Substantially less expensive to construct than prior arrangements, the apparatus is able to measure the spacing between adjacent bar-coded characters and reject any data if the character spacing is greater or less than is proper at any given point in a data scan.  It thus becomes difficult for an erroneous scan to result when a scanning motion reverses itself, begins in the middle of a bar code, or extends over two independent bar codes.

Abstract: PROCESS FOR PRODUCING POTATO CHIP FLAVOR CONCENTRATE     Michael R. Sevenants Abstract of the Disclosure A process for producing a potato-chip flavor concen-trate which comprises the steps of heating a potato material until a browned product is formed; extracting the browned potato material with a solvent; contacting the extract with a cation-exchange resin, thereby to adsorb flavoring compounds onto the resin; and eluting the adsorbed flavoring compounds from the resin by means of a suitable solvent.  Preferred process conditions involve heating comminuted potato material, slurrying the browned potato material in a water-and-alcohol extraction solvent, contacting the resulting extract with a cation-exchange resin and eluting the adsorbed flavoring material by addition of a strong base or acid.  The potato-chip flavor concentrate can advantageously be added to potato chips and other potato products, especially those prepared from dehydrated potatoes.

Abstract: A METHOD OF AIR LETTING AN EVACUATED                   CATHODE RAY TUBE     Abstract A weight is placed on the electrical connection pins extending from the stem of a cathode ray tube having a funnel portion and a neck portion.  The neck portion is circumferentially cracked completely through between the funnel portion and the stem.  The stem and the neck portion are placed within a hermetic chamber which is evacuated until the-stem having the weight thereon separates from the funnel portion at the circumferential crack in the neck portion.  The separated stem trips a switch which terminates the evacuation and enables the admission of an inert dry gas in a gradual manner to prevent contami-nating particles from being conveyed inside the open tube. When the pressure of the inert gas inside the hermetic chamber is substantially equal to atmospheric pressure outside the chamber, the open tube is removed for further processing.

Abstract: ANTON H. OSWALD THREE-POSITION FLASHLIGHT SWITCH      ABSTRACT OF THE DISCLOSURE           The switch includes a housing and an actuating member which is slidably mounted for movement along the housing between first, second and third positions and has a pushbutton depress-able in a direction perpendicular to said movement between normal and depressed position.  First and second contacts are mounted on the housing.  The second contact is flexible and movable by the actuating member between a position wherein the contacts are engaged thus completing an electrical circuit and a position where the contacts are space from each other.  The actuating member and the second contact each have a surface extending in the direction of the sliding movement of the actuating member and a surface which is generally inclined with respect to that surface in the direction away from the second contact.  The corresponding surfaces are out of alignment when the actuating member is in the first position, such that the depression of the pushbutton is ineffective to cause movement of the second contact into the engaged position.  The corres-ponding surfaces are in alignment when the actuating member is in the second position such that depression of the pushbutton causes engagement of the contacts.  The corresponding inclined surfaces coact, as the member slides along the housing from the second to the third position, to move the second contact into engagement with the first contact and in this position, the surface of the actuating member which extends in the direction of sliding movement of the member is effective to retain the contacts in the engaged position.
