Title: Guide and support structure for surface cutting apparatus
Inventor: BIERI HANS
IPC: B28D1/04
Filed: 1992-01-17
Abstract: ABSTRACT OF THE DISCLOSURE.          To permit continuous selected   longitudinal adjustment of a support block (8, 34) with respect to a support surface.(S) along the length of an elongated rail element (1), an attachment base is formed on the rail element which interfits with a   projectin-and-recess fit with a portion of the support block.  A clamping arrangement (7) can clamp the interengaging projection-and-recess portions together; preferably, they form a dovetail connection, with a movable clamping Jaw which clamps both against the attachment base and the support block structure.  The support block may include a plate, adjustably positioned over the surface by adjustment screw bolts, or a rod or tube element, so that the rail can also be tilted about the axis of the rod or  tube element.

Abstract: PHA 21.661                                          10.03.1992 Abstract: High pressure gas discharge lamp.     An improved high pressure gas discharge lamp. The lamp contains a standard arc tube (10) having electrodes (13) disposed at each end. The outer surface of at least one end of the arc tube is coated with a layer (14) of high radiative emissive material such as graphite or carbon. The coating serves to increase the radiative output of the arc tube at its so called cold spot so as to cool the cold spot. The coating greatly decreases the voltage variation from lamp to lamp and permits manufacture of lamps within tighter voltage tolerances than have hitherto been achieved.

Abstract: ABSTRACT OF THE DISCLOSURE    An  improved  transport medium  contains  a  non-ionic detergent, preferably saponin for lysing white blood cells is used in the transport of microbiological samples from mammalian  body  sites.    The  improved  transport  medium contains a lytic agent, preferably saponin to quickly lyse white blood cells present in the sample, which may destroy the microorganisms and their antigenic sites.  The preferred lytic agent saponin is present in a concentration from about 0.1  mg  to  about  10  mg,  saponin/ml  transport  medium, preferably from about 0.5 mg up to about 2 mg saponin per ml transport medium, more preferably about 0.75 to about 2 mg saponin per ml transport medium, and most preferably in a concentration of about 1 mg saponin per ml transport medium. Furthermore, these detergent lytic agents may be combined in the  transport  medium  with  phospholipids,  suitably  L-a Lecithin (phosphatidylcholine) which forms mixed micelles that  protect  saponin.     Other  phospholipids  include phosphatidylserine, phosphatidylinositol, phosphatidic acid, phosphatidylglycerol,    phosphatidylethanolamine    and sphingomyelin.  If the viability of the microorganisms is to be preserved,  the improved transport medium should also include suitable buffers and a carbon source to allow the survival of the microbiological sample.  Preferred transport media suitable for use in the present invention include modification (by the addition of saponin) of the following media:  (1)   Amies Transport Medium Without Charcoal,  (2) Amies Transport Medium With  Charcoal,  and  (3)    Stuart Transport Medium.
