Title: Merchandise display rack with reinforced bases
Inventor: BENVENUTI FRANK
IPC: A47B57/42
Filed: 1993-10-18
Abstract: ABSTRACT OF THE DISCLOSURE       MERCHANDISE DISPLAY RACK WITH REINFORCED BASES           Disclosed is a merchandise display rack also known as a "gondola", in which each post has a bottom and from which two flat tabs horizontally extend away in the same direction as hookable half-bases used to hold the post vertical.   A retaining pin is rigidly connected to each half-base or tab is in such a manner as to engage and fit into a corresponding hole made in the corresponding tab or half-base when this half-base is rigidly connected to the post.  As a result, most of the shearing force that usually applies to the lower hooks of the half-bases when the rack is  loaded  with    merchandise  onto  one  size  only,  is transferred to the tabs by the retaining pins,  thereby making it possible for the rack to receive a heavier load on this one size.

Title: Process of protecting surfaces using silicate compounds
Inventor: CREWS NATHAN C IV
IPC: B05D3/10
Filed: 1992-05-22
Abstract: A process for forming a protective barrier (14) on metallic or wood surfaces to provide protection against abrasion, corrosion, heat, and fire. The process comprises by first forming a fixed surface (12, 16) on the metallic or wood article. On metallic articles (10), the fixed surface (12, 16) is formed by cleaning the surface and then exposing the surface to concentrated phosphoric acid. On wood, the fixed surface is formed by thoroughly cleaning the surface with hot water and detergent only. After the fixed surfaces are prepared, it is then exposed to a 10-16 % silicate salt for at least one minute and then allowed to dry completely at 305 degrees Fahrenheit to form a first layer (18) of silicate salt over the fixed surface. During the drying process, a portion of sodium silicate is converted into silicon dioxide. A plurality of sodium silicate layers are then formed over the first layer of sodium silicate layer. After the last layer of sodium silicate is formed, it is then exposed to concentrated phosphoric acid to form a bi-layer (22) thereon comprising an inner layer (20) of sodium silicate and an outer layer (24) of silicon dioxide. In an alternative method, each sodium silicate layer is exposed to concentrated phosphoric acid to create a plurality of bi-layers over the fixed surface.

Inventor: KUROKAWA TSUTOMU
IPC: C12N15/12
Filed: 1993-12-21
Abstract: ANTIBODIES, POLYPEPTIDES, PRODUCTION AND USE THEREOF             ABSTRACT The present invention relates to a glia activating factor (GAF) in which 33 to 49 N-terminal amino acids are deleted from the N-terminus of the GAF polypeptide of SEQ ID NO: 3, as well as an anti-GAF antibody which is highly sensitive to assay the GAF and is capable of neutralizing GAF's activity, is produced.      Using the antibody, GAF and its biological activity can be assayed easily with high sensitivity.  Further, the neutralizing antibody can be expected to have preventive and curative effects on diseases caused by GAF's excessive action.  Furthermore, the GAF polypeptide disclosed herein is more stable to acids and heat than the conventional GAFs, therefore, it can be used as a platelet-increasing agent, etc., more advantageously than the previously known GAFs.

Title: Method and apparatus for determining the solid fraction of a stored cryogenic refrigeration system
Inventor: BURGERS KENNETH L
IPC: G01N27/64
Filed: 1993-09-02
Abstract: In the method of the invention, an unknown mass fraction (F) of solid cryogen in a stored cryogenic refrigeration system is determined. The method includes the steps of adding mass (T) of a trace substance which is soluble in the liquid phase of the system.  The total mass amount (M) of the cryogen in the system is determined at the time of charging the system. The initial mass concentration (CI) of the trace substance is determined by dividing (T) by (M). During operation of the stored cryogenic refrigeration system, a small sample of the liquid phase cryogen is extracted from the system. The sample is analyzed to determine the new concentration (CN) of the trace substance in the sample. The new concentration (CN) of the sample is dependent on the amount of solid cryogen which has been produced in the system. Thereafter, the mass fraction (F) of solid cryogen in the system is determined by solving the equation: F = 1 - (CI/CN).
