Title: Fireproofing agent and its use
Inventor: BALLE HEINZ
IPC: C09K21/02
Filed: 1991-04-26
Abstract: ABSTRACT OF THE DISCLOSURE           The fire-proofing agent contains at least one dehydrogenizing agent.  It also advantageously contains a carbohydrate or a starch as binder.  The following may be used as the dehydrogenizing agent: phosphate salts, urea, boric acid, aluminum hydroxide, while carbohydrates or starches are used as binders.  In addition to these fundamentally important and generally appointed components, propellant charges and stabilizers as well as other additives, as for, instance, binder additives or synergists, can also be contained in the fire-proofing agent according to the invention.  The fire-proofing agent is basically applied by adding it to the material or product itself and by impregnation after-treatment of a raw material, semi-finished product. Impregnation may take place, for instance, by an immersion procedure, or by spraying or brushing the fire-proofing agent onto the material to be treated.  The specific composition of the fire-proofing agent can be varied in accordance with the intended application.

Title: Liquid vaporizing, diffusing and dripping
Inventor: ZLOTNIK MILTON
IPC: A61L9/12
Filed: 1992-09-30
Abstract: Apparatus including a liquid vaporizer having a first wick of linear shape, a bottle for holding the liquid to be vaporized and a gravity-flow metering device having a second wick. The bottle has a closing cap to which two tubes are connected. One tube discharges the liquid from the bottle and the other extends through the cap to the opposite end of the bottle for counteracting the vacuum which is produced when liquid is discharged. The end of the discharging tube extends outwardly of the cap further than the end of the other tube so that a pool is produced in the dispenser. The level of the pool is limited by the position of the end of the tube for counteracting the vacuum. The second wick is of J-shape; one end is immersed in the pool and the other end is suspended over the first wick so that liquid absorbed at the immersed end drips from the second wick on the first wick and is evaporated and diffused from the first wick. There is also disclosed a bottle having a spout with two holes near its end; the lower hole for dis-charging the liquid and the upper hole for admitting air to counteract the vacuum. There is also disclosed a method of vaporizing and diffusing a liquid whose steps include absor-bing a liquid in a first wick and dripping the absorbed liquid on a second wick from which it is vaporized and diffused.
Patent CA-2081492-A1 (CA)
Inventor: HOEPKER ELMER-CHRIST
IPC: F16B19/14
Filed: 1992-10-27
Abstract: A nail fastener assembly for attaching thin metal sheets includes an axially extending nail with a comically shaped shank having ballistic-like tip at its leading end and a head at its trailing end. A disk is fitted on the leading end of the shank with a sleeve secured on the shank between the disk and the head. When the nail is driven by a setting tool, the sleeve acts on the disk in the region of the tip, so that the transmission of all forces acts on an annular radially outer surface on the leading surface of the disk. The leading end surface of the disk has a radially inner comically shaped first recess and an annular second recess encircling the outer edge of the first recess and spaced inwardly from the radially outer edge of the disk.  Accordingly, the radially outer contact surface bears against the metal sheet being attached and provides high transverse stresses.

Patent CA-2086187-A1 (CA)
Inventor: JANES RICHARD
IPC: A63B49/08
Filed: 1992-12-23
Abstract: ABSTRACT           A handle pallet for a tennis racquet includes an elongated rigid underlayment member formed integrally with the racquet head in a one-step compression molding operation,  to  form  a  one-piece  racquet  head/handle pallet underlayment member article.   The underlayment member generally is octagonal-shaped, and includes sides having  a  concave-shaped  exterior  surface  and  sides having a flat exterior surface, with the widths of the sides being generally uniform.  Spaced elongated edges of the sides form prominent, outwardly directed ridges at each interface of pairs of said edges for indexing of the racquet orientation by the player.   An elongated soft overlayment member also is octagonal-shaped and is disposed on the underlayment member for shock absorp-tion.  The sides of the overlayment member each have a flat exterior surface, and the interior surface of the overlayment member is complementary in shape to the exterior surface of the underlayment member.  The width of the overlayment member is variable due to the con-cave-shaped sides of the underlayment member, so that the handle pallet  is  lightweight  and maintains the indexing  function  of  the  underlayment  member,  yet provides excellent shock absorbency for the player.

Abstract: A method for recovering viable cells having surface protein determinants having portions rich in O-glycosylated carbohydrates is provided. The proteins have determinants which are substrate sensitive to a P. haemolytica derived neutralmetallo-glycoprotease. The glycoprotease has highly restricted specificity for cleaving solely from the cell surfaces the O-glycosylated protein portions having the determinants while retaining cell viability. The process comprises: i) contacting the cells in solution with affinity matrices which bind specifically to one or more of the determinants which are part of the glycoprotease sensitive substrates, the affinity matrices are allowed to bind to the determinants on the cells, ii) separating the cells to which the affinity matrices are bound from any remaining matter in the solution, the affinity matrices having sufficient binding affinity for the determinants to remain bound to the determinants during the separation, iii) contacting the glycoprotease with the separated cells in sufficient concentration and duration to cleave solely the protein substrate portions having the determinants and bound by the affinity matrices and thereby release the cells from the affinity matrices, the released cells retain viability due to the restricted specificity of the glycoprotease cleaving solely O-glycosylated protein portions having the determinants, and iv) recovering the released cells.
