Abstract: ONE-WAY EVACUATED TUBE STOPPER     ABSTRACT OF THE DISCLOSURE          A stopper for an evacuated tube with an open end for collecting fluid such as blood samples.  The stopper includes a plug adapted to be mounted in the opening in the tube so as to normally seal the tube.  The plug permits access of a fluid sample needle therethrough into fluid communication with the reduced pressure interior of the tube so that fluid is collected in the tube from the needle.  A check valve is on the plug to automatic-ally open when the needle is inserted through the plug and sub-jected to the reduced pressure in the tube and to automatically close when subjected to a predetermined amount of pressure from within the tube such as that caused by backflow thereby prevent-ing any fluid passing into the needle from the tube.  The check valve includes a chamber which can be used as a reagent holder prior to tube use.

Abstract: CLEANING HEAD AND METHOD            ABSTRACT OF THE DISCLOSURE          A cleaning head for use in a water extraction cleaning process comprises a suction chamber for connection to a source of suction and having an open mouth.  An inner compartment is arranged substantially centrally within the suction chamber and has side walls defining an open mouth in the plane of the open mouth of the suction chamber.  Associated with the inner compartment there is a cleaning liquid delivery duct formed with a plurality of closely spaced fine outlets adapted to allow cleaning liquid to flow substantially dropwise into the inner compartment at a position spaced from the mouth thereof.  When the cleaning head is applied to a surface to be cleaned, cleaning liquid is applied to a part of the surface which is shielded from air flow but arising from vacuous conditions within the suction chamber, but, upon movement of the cleaning head in either of at least two opposed directions, the area then wetted by the cleaning liquid is immediately subjected to suction drying.

Abstract: ABSTRACT OF THE DISCLOSURE        System of transferring wane-edge boards through a control station for edging to detect the wane consistent and possibly other characteristics of the board automatically.  The board is first aligned automatically by transporting each board separately and sequentially against a first group of fixed trans-versal stops to provide the same sawing line for each sequentially fed board; then each is moved sequentially from the transversal stops to and through a control station where the wane consistent and other features may be detected. The information is recorded in a data processing unit memory, and then the board is trans-ferred to an edging station and aligned against a second group of transversely positioned adjustable stops. The movable stops are optimized in the basis of information supplied by the data processing unit based on quantities measured at the control station and other information so that each of the boards is transferred to the same sawing line. The aligned board is then charged into an edging machine along a sawing line which is predetermined at the control station.

Title: Multi-purpose pre-mix for home baking  processes
Inventor: HENSELMAN MARLENE R
IPC: A21D2/00
Filed: 1978-10-31
Granted: 1981-12-29
Abstract: Abstract of the Disclosure A specially prepared multi-purpose bakery product pre-mix together with processes for its preparation and use in home baking procedures, characterized by flexibility and adaptability of use in rapidly preparing a wide variety of yeast and/or chemically leavened bakery products in the home, for example, bread, rolls, coffee cake, pancakes, waffles, biscuits, pizza crust and the like.  The pre-mix makes use of specially prepared dry ingredients including low moisture, special protein flours (protein content 9 to 12%, moisture content below 8%), finely divided, porous, low moisture, highly active yeast (moisture content below 5%), dry sub-divided shortening (moisture content below 2%), and sucrose and salt flavoring.  Chemical leavening agents such as baking powder, dried whey (moisture content below 4%), and various dough modifying and improving agents (e.g., cysteine and bromats, monocalcium phosphate, mono- and di-glycerides, sodium and calcium stearoyl lactylates, etc.) can also be incorporated in the pre-mix.  The pre-mix product is prepared by mixing the dry ingredients, separa-ting and isolating a portion of the mixed dry ingredients, and packaging and sealing such isolated portion in an oxygen and moisture excluding enclosure to form a pre-packaged pre-mix.  Such pre-mix is characterised by a total aggregate moisture content within the sealed package of less than 8% and an extended storage or shelf-life ranging up to 12 months.           At such time as the pre-mix is to be used in a particular home baking process, the sealed pre-mix package is opened and a measured quantity removed in accordance with the particular desired home baking recipe, following which moisture excluding environment for the balance of the packaged pre-mix.  In general, the pre-mix ingredients are used by simply pouring the same from a pre-mix package into a mixing bowl, adding water and additional ingredients as called for in the particular recipe and then mixing to form a dough or batter, as the case may be, in accordance with the particular baking process.  Thus, when the consumer wishes to make chemically leavened products such as biscuits, the pre-mix may be combined with water and immediately placed in the oven, the baking time being insufficient to activate the yeast.  Should the consumer wish to make leavened bread, the pre-mix is mixed with water to form a dough following which the dough is kneaded, divided, proofed and baked in normal fashion to make a leavened bread.  Further variations in the use of the pre-mix enable the production of partially yeast and chemically leavened products, such as pizza crust.

Abstract: ABSTRACT           An automotive trim strip laminate formed of a thin strip of polyester material bearing a layer of metallic material and bonded to a substrate of a poly-vinyl chloride material is made so that the laminate can be thermally bonded to a support material along a curved path without any wrinkling or other irregularity. This is done by longitudinally tensioning the laminate after it has cooled below its annealing temperature following extrusion of the substrate to strain the laminate sufficiently 50 that it tends to shorten upon reheating to its annealing temperature, The strain is insufficient to cause strain-relief shortening of the laminate at ambient temperatures encountered during storage and transport but is sufficient so that when the strained laminate is held accurately to the curved path and thermally bonded to the support material, its thermal expansion cooperates with strain relief to bring the laminate into smooth and uniform conformity with the curved path.
