Title: Hyposensitization agent
Inventor: MATSUHASHI TYOKU
IPC: A61K31/70
Filed: 1990-08-28
Abstract: Abstract of the Disclosure A novel  hyposensitization  agent  was  prepared  by covalently attaching a saccharide to a cedar pollen allergen having a partial amino acid sequence of Ala-Ile-Asn-Ile-Phe-Asn- beginning at its N-terminal.  The hyposensitization agent, when compared with an intact cedar pollen allergen, extremely accelerates the production of immunoglobulin G and M antibodies which  are  specific  to  intact  cedar  pollen  allergen,  but extremely reduces the production of immunoglobulin E antibody which is specific to the allergen.  Thus, the hyposensitization agent is administrable to cedar pollinosis patients with no anaphylaxis and allergy, and cuts hyposensitization period to about 1/3 to 1/200.

Title: Method and apparatus for fiber cooling
Inventor: CAIN MICHAEL B
IPC: G02B6/44
Filed: 1991-01-07
Abstract: ABSTRACT OF THE DISCLOSURE      A  liquid  cooling  method  and  apparatus  for  rapid cooling of a hot glass fiber.   In Fig. 1, an open ended liquid coolant container (12) is provided at its lower end with  an  inverted  funnel  surface  (34).   A  vertically running,  hot  glass  fiber  (42)  of  indefinite  length  is continuously drawn through the container, as the container continuously receives a coolant liquid at its upper open end  (30).   The  liquid  continuously  drains  from  the container lower open end (32) by flowing along flow surface (36) of the inverted funnel (34), downwardly and away from the  glass  fiber  (42).   The  temperature  of  the  fiber relative to the temperature of the coolant liquid is such that a vapor barrier surrounding the hot fiber is formed due to boiling of the liquid in a zone surrounding the fiber. This vapor zone facilitates diversion of the liquid (change in direction of flow) from the vertical to an angle thereto,   along   the   inverted   funnel   surface.    The substantially cooled hot  glass  fiber passes  out  of  the container lower end for further processing, such as coating the fiber.  The method and apparatus yields cooled glass fiber not wetted by the coolant liquid.

Title: Low watt metal halide lamp
Inventor: GRAHAM TIMOTHY W
IPC: H01J61/20
Filed: 1991-02-22
Abstract: A metal halide arc discharge lamp is disclosed having a power input rating of not more than 35 watts. The lamp comprises an envelope of light transmissive material, such as fused quartz, including a bulb portion (26), a pair of transitional neck portions (24, 24') extending from the bulb portion (26), and a pair of stem portions (22, 22') extending from the transitional neck portions (24, 24') respectively. The bulb portion (26) of the envelope defines an arc chamber (28) therein and has an external surface area of such value as to produce a wall loading not exceeding 35 watts /cm2. The arc chamber (28) contains a fill of mercury, inert gas and metal halide. The mercury and the metal halide are adapted to substantially vaporize during operation of the lamp. A pair of electrodes (30, 30') extend into the arc chamber (28) from the pair of neck'portions (24, 24') respectively. Each electrode has an electrode tip spaced apart from one another by a distance A (FIG. 2) within the arc chamber (28). The neck portions (24, 24') of the envelope each have a wall surrounding a segment of one of the electrodes (30, 30'). The walls of the neck portions (24, 24') each have a stretched section with a minimum wall thickness not exceeding about 1.5 mm. A pair of inlead assemblies are electrically coupled to the pair of electrodes (30, 30') respectively. The inlead assemblies pass from the electrodes (30, 30') through a hermetically sealed section in the stem portions (22, 22') of the envelope to the exterior of the lamp.

Title: Method and apparatus for metalizing internal surfaces of metal bodies such as tubes and pipes
Inventor: BERNSTEIN PHILIP JR
IPC: C23C24/10
Filed: 1991-02-28
Abstract: ABSTRACT         A method for metal coating the inside surface of an elongated metal tubular body which includes placing a plurality of elongated pieces of coating metal into the bore of the tubular body in parallel alignment with the axis of the tubular body and in position within the bore to provide a substantially constant amount of coating metal along the axial length of the bore.  The coating metal has a melting point which is below the melting point of the tubular  body.    The  bore  of  the  tubular  body  is  rendered substantially free of oxygen by evacuation or by purging with an inert gas.  The tubular body and the elongated pieces of coating metal contained within the bore are rotated at a high rotational speed sufficient to distribute the elongated pieces against the bore surface while maintaining the substantially constant amount of coating metal along the axial length of the bore.  The rotating tubular body is then heated sufficiently to melt the coating metal pieces and insufficiently to melt the tubular body.  The melted coating metal is spread about the bore surface by means of the centrifugal force imposed upon the melted coating metal by the continued rotation of the tubular body.  The rotating tubular body is then passed from the heating zone into a cooling zone, and the tubular body is then withdrawn from the cooling zone with a uniform layer of solid metal coating upon the bore surface.

Title: Glidemaster

IPC: B25H5/00
Filed: 1991-03-12
Abstract: ABSTRACT       Machines that an operator uses to gain access under vehicles without raising them off of the ground consist of platform under which wheels are mounted. In this invention wheels of various diameters and widths can be used without raising the height of the platform and that of the operator. An increase in platform height would result if larger wheels were mounted in a conventional manner preventing access under many vehicles. In this invention wheels are mounted at the end of bars attached to the platform that are angled and extend out widthwise from the platform and upward from the height of the platform to provide a mounting point for large wheels outside the platform itself. This allows wheels to be used that will not be impeded in their operation on irregular surfaces, surfaces with debris on them, unpaved and non-compacted surfaces. The particular angle, dimensions, attachment points and shape of the bars are modified to accomidate the wheel chosen for a particular surface while maintaining the machines low platform height. Modification in the platform shape and width at the bar attachment site is required as well to minimize machine width and to provide for unimpeded wheel operation.                      SPECIFICATION

Abstract: An  otherwise  conventional  mine  roof  expansion anchor  of  the  bail-type  is  provided  with  a  tubular retainer member encircling the shell leaves and having an  external  cross-dimension  significantly  (e.g.,  at least .10") greater than the diameter of the drill hole in which the anchor is to be installed.   Thus, as the anchor, supported on the end of a roof bolt, is advanced into the drill hole in the usual manner,  the tubular element is pushed off the anchor by contact with the surface surrounding the drill hole, thereby eliminating the previously required manual removal of the retainer.          The  tubular  retainer  has  the  same  cross-sectional configuration in all planes perpendicular to its central axis throughout its full length, preferably being formed as a plastic extrusion.
