Abstract: A method in the activation of lignocellulosic material with a gas containing nitrogen dioxide ABSTRACT     The present invention relates to a method of activating aqueous lignocellulosic material with a gas containing nit-rogen oxide,  followed  by a  delignification stage for  the purpose of obtaining a high quality end product with no or only a slight effect on the environment. In accordance with the  inventive  method,  the  lignocellulosic  material  is brought  into  contact  with  an  oxygen-containing  gas,  and activating gas is separated from the lignocellulosic mate-rial during and/or subsequent to the activating process. The method is characterized by controlling the supply of oxygen--containing  gas  such  that  the  separated  gas  contains  at least 2 kg nitric oxide (NO) calculated on 1000 kg of dry lignocellulosic material, and by reacting the separated gas in one or more stages with absorption solution whose origi-nal pH lies within the range 3-13.5, and by passing the gas purified with the aid of absorption solution to atmosphere, or to a destruction plant, optionally subsequent of further purification of the gas.

Abstract: ABSTRACT        A method of packaging goods within a packaging casing in which a substantially gas impermeable cup-shaped first casing part is provided having a depres-sion and a peripheral lip.  A web of gas permeable skin packaging material is placed over the depression and spaced from the bottom of the depression to form a space therebetween.  A gas is then provided in the space.  The web is sealed to the peripheral lip provid-ing at least atmospheric pressure above to create a pressure differential above and below the web resulting in the web being stretched down inwardly of the depres-sion.  Goods are placed over the web, and an outer cas-ing member is placed over the goods and the lip so that the permeable web is further stretched.  The outer cas-ing member is then sealed to the lip so that gas in the depression is allowed to permeate over an extended period of time through the web to the goods to enhance the keeping qualities of the goods.

Title: Method and apparatus for automatic vapor cooling device for shape melted components
Inventor: DOYLE THOMAS E
IPC: B23K37/00
Filed: 1989-01-25
Granted: 1995-06-27
Abstract: A method and apparatus for automatically cooling a workpiece being manufactured by shape melting whereby a gas/liquid coolant mixture is pumped onto the external surface of the part to be cooled.  Temperature and pressure data is fed to a computer control system which regulates the flow of the gas and liquid coolant mixtures.  A suction device which enshrouds the spray head extracts the heated and vaporized fluid from the vicinity of the surface.  The apparatus may be provided with multiple spray heads which comprise the cooling head and have the ability to control the total rate at which coolant flows through the device by individually controlling coolant and gas flow through each of the multiple spray heads.  If more cooling is desired, the computer control system activates more nozzles for flow, or it increases flow rate through already activated nozzles.  Both the number of spraying heads and flow rates through each spray head are variable, so the cooling capabilities of the system are continuously variable over a wide range of total flow rates through the device.

Abstract: ABSTRACT OF THE DISCLOSURE        A track has walls which enclose a hollow interior and among these walls are two laterally directed flanges which are separated by a slot that opens downwardly out of the track for the full length of the track.  The track contains trolleys having wheels which roll along flanges of the track and the trolleys carry hangers which depend through the slot in the track and are attached to a door or some other suspended device.  One of the trolleys also carries a latching mechanism which engages a keeper located within the track to secure the trolleys and suspended device in a predetermined position along the track.  The latching mechanism includes a latch bar which pivots on the trolley between engage and release position and a spring which urges the bar to its engage position--the position in which it will engage the keeper upon encountering the keeper.  The latching mechanism also includes a release cord which depends from the latch bar through the slot in the track and, when pulled, causes the latch bar to pivot against the bias of the spring.

Abstract: ABSTRACT      Prior art fasteners for attaching trade or price tags  to  an  article  have  limited  length  and  therefore cannot be used on bulky, thick articles.  The invention is a fastener assembly comprising a plurality of fasteners joined by a string and which may be separated from the assembly.  Each fastener comprises a female member having an opening, a male member engageable in the opening, and a string member comprising a portion of the string joining the  fasteners.    The  string member passes  through  the female  and male members  which are  fused to  it.   The individual fasteners are obtained by cutting the string between adjacent male and female members of the adjacent fasteners.   The  string between each pair of male and female members may be adjusted in length to provide a fastener of any suitable length.

Abstract: ABSTRACT      A  mirror (10) having optical quality reflective faces (14) is prepared by pressing of metallurgical powers.  An optical quality surface (14), free of scratches and irreg-ularities, is formed by pressing the faces with an optical quality tool face (44), applied to the face at a acute angle to achieve a degree of metal flow.  The mirror (10) is progressively formed, by first pressing an assembly of powder to a "green" powder mirror, sintering the pressed powder, and then repressing the sintered mirror using a tool having optical quality surfaces on the faces contact-ing the mirror faces.  The mirror is annealed, repressed with the tool having optical quality surfaces, and coated on the reflective surfaces with a thin metallic coating. This technique is particularly effective for preparing large numbers of mirrors with multiple facets requiring precise facet intersections, as the pressing tool can be adjusted to produce highly exact facet intersections which are then reproduced exactly in subsequent mirrors.

Abstract: Abstract of the Disclosure An electrode unit for use in an analyzer of blood and of liquids includes a cylindrical outer housing having open ends and a pair of top hat end plate bushings each having a central bore and a plug portion, the bushings being positioned in each end of the housing with the plug portion directed into the housing to form a filling chamber with the inner surface of the housing.  The chamber is filled with an ion conducting solution, and a silver-silver chloride electrode is mounted on the outer housing and extends into the ion conducting solution.  A sodium glass capillary tube is mounted in the bores of the bushings and extends between the bushings through the ion conducting solution in the chamber, with the sodium tube being sealed to the bushings and the bushings being sealed to the housing.  An annular groove is formed in an end flange portion of each bushing so that a connecting alignment ring may seat in the bushing annular grooves of two adjacent electrode units to center the electrode units.  The height of the connecting alignment ring is smaller than the depth of the two annular grooves of the connected bushings so that the outer faces of the bushing flanges may be pressed against each other to form a tight connection and avoid leakage of the liquid passing between adjacent electrode units.

Abstract: Printed products and their respective corresponding printing plates are divided into a plurality of image elements. For each image element the surface coverage is determined by photoelectric measurements; a reference reflectance value is then calculated from these measurements, taking into consideration such parameters as the printing characteristic. These reference reflectance values are compared with the actual reflectance values measured on the printed products and the results of the comparison are evaluated to form a quality measure and to calculate control values for the ink feed devices of the printing machine. In this manner, the use of special color measuring strips may be eliminated.
