Abstract: PCT No. PCT/NO80/00017 Sec. 371 Date Jan. 16, 1981 Sec. 102(e) Date Jan. 9, 1981 PCT Filed May 14, 1980 PCT Pub. No. WO80/02579 PCT Pub. Date Nov. 27, 1980.An anchorage for attachment of ties to walls, floors and ceilings of various kinds, e.g. for attachment of a facing to a concrete wall, consists of a tubular aluminum section (1) having a longitudinal slot for introduction of one end (6) of the tie (5). The slot of the section is provided with edge portions (4) which are curved outwardly so that their end portions extend about tangentially with respect to the cross section of the section. At the opposite side of the slot the section is provided with attachment flanges (2). The tie (5) consists of a cold-drawn stainless steel wire which at one end is looped to an eye (6), the free end (14) of which being bent transversally and extending some distance outwardly in order to prevent twisting of the tie in the anchorage section. The other end is provided with a transverse portion for securing in mortar or for cooperation with a safeguarding plate (12). The safeguarding plate has two holes (13) which the stem portion and free end portion (11) of the tie may be threaded through in order to prevent relative motion between the safeguarding plate and the tie.

Title: Glass feeder tube support
Inventor: MUMFORD EUSTACE H
IPC: C03B7/084
Filed: 1984-10-09
Granted: 1990-11-06
Abstract: ABSTRACT OF DISCLOSURE    The feeder tube in a molten glass gob feeder is mounted in a holder which is supported in the feeder structure by a pair of opposed hollow shafts.  The shafts are vertically adjustable by the fact that they have their lower ends threaded onto vertical screws.  The vertical screws are mounted for rotation about their vertical axes, in unison, to effectively raise or lower the shafts as desired.  A scale and pointer arrangement indicates the tube height relative to the feeder bottom.  The feeder tube is mounted in the holder such that reciprocation of a plunger in the tube will not raise the tube relative to the feeder.

Title: Vessel for transportation of high melting aromatic hydrocarbons in liquid phase
Inventor: PFEUFFER MICHAEL
IPC: B63B25/08
Filed: 1987-04-07
Granted: 1991-04-16
Abstract: ABSTRACT OF THE DISCLOSURE         In double-hulled vessels for transporting hot pitch at temperatures of 200-300°C, an effective thermal insulation of the tanks and inhibition of their gas spaces against chemi-cal reaction are two important factors.  Allowance is made for thermal expansion by means of expansion joints and sliding bearings.  Due to the high solidification point of the mate-rial, all the pipelines must be heated and sufficiently insu-lated.  A hot oil installation is provided for both pipeline heating and also for emergency heating of the tanks.  Separate ballast tanks are disposed between the hulls since the tanks may not be filled with water.  The vessel must be equipped to comply with safety regulations for class K1 vessels.

Title: Mobile self propelled crushing machine
Inventor: BARBIERI ELDA
IPC: B02C21/02
Filed: 1987-07-03
Granted: 1991-07-02
Abstract: ABSTRACT A mobile, self-propelling crushing machine includes a structure essentially consisting of two beams, on which a central frame is welded. The central frame houses a rotor which is supported on a frame, which, in one form, is lowered by hydraulic cylinders fixed to the frame. In another form, the frame is lowered by four mechanical jacks being driven by a single hydraulic motor. Thus, the penetration of the rotor into the soil to be treated does not depend only on its own weight, but especially on the action of the just-mentioned hydraulic cylinders or mechanic jacks. The rotor is driven by two hydraulic motors which are opposite to one another and which are self-adjusting so that when a pressure transductor signals a pressure increase to the hydraulic motors of the rotor due to an increased effort, the forward movement speed of the machine, which moves on tracks, decreases as a consequence.

Title: Size independent modular web processing line and modules
Inventor: STEIDEL LEONARD R
IPC: B65H23/188
Filed: 1987-09-10
Granted: 1991-03-26
Abstract: SIZE INDEPENDENT MODULAR WEB  PROCESSING LINE AND MODULES        ABSTRACT OF THE DISCLOSURE        Modular web processing units may be physically and electrically assembled into clusters to perform various web processes (e.g. the production of paper forms such as invoices, checks, labels, etc.). Each module has a main process driver which is not directly coupled to a web drive mechanism.  Rather, the web drive is program controlled so as to effect the desired web process at controlled displacement intervals along the web.  Accordingly, a plurality of successive but different form lengths or depths can be accommodated as the web surface is sequentially processed.  A system of such modules can be physically wheeled into position as individual units and electrically connected together by suitable umbilical cords to rapidly configure a desired overall web finishing process.  Nevertheless, the entire ensemble of modules performs as though it is a unitary special purpose web processing machine with its various process stations interconnected and synchronized by an electronic "drive shaft".  One of the modular units automatically becomes the master source of process drive pulses for the others and the entire ensemble may be controlled from the control panel of any one of the modules.  Examples of modules for unwinding web from a roll, for folding processed web, for printing and for perforation or cut-off are described.

Title: Carton with improved handle
Inventor: SCHUSTER RICHARD L
IPC: B65D/
Filed: 1988-03-25
Granted: 1993-06-22
Abstract: Abstract of the Disclosure A carton contains a flap on the outer top panel and a flap on the inner top panel, the free edge of the outer top panel flap overlying the inner top panel flap.  When a user presses down on the outer top panel flap,  it pivots out of the way to allow the user's fingers  to  fold  the  inner  top  panel  flap  under  the  top  panel structure to provide a handle for  lifting  the carton.   When the fingers are withdrawn, the outer top panel flap is biased upwardly by its arcuate foldable connection to close the handle opening.  If the inner top panel flap is contacted by the outer top panel flap as it pivots upwardly,  the outer top panel flap pushes the inner top panel  flap  up  to  a  substantially  closed  position.   Score  lines extending from the ends of the foldable connections of the inner and outer top panel flaps to the corners of the carton distribute the lifting stresses to the side panels of the carton.

The latter can be mounted in or on a   frame for the cleaning implement or is movable along the roll independently of the cleaning implement.  The apparatus can be mounted at the inlet or outlet side of the nip of the calender roll with a companion roll.  The frame for the cleaning implement can carry one or more nozzles which direct water or another liquid (such as a solvent) against the cleaning implement and/or against the roll, and one or more nozzles which blow jets of air against the periphery of the roll.

Title: Riboflavin producing strains of microorganisms, method for selecting, and method for fermentation
Inventor: HEEFNER DONALD L
IPC: C12N15/04
Filed: 1988-05-25
Granted: 1993-04-27
Abstract: Abstract Strains of yeast of the  species  Candida  flareri are  disclosed which can produce 10 grams of riboflavin per liter in 6 days,  and in particular,  strains iden-tified   by  ATCC  Accession  Nos.   20849  and  20850. Riboflavin yields of more than 20 grams  per  liter  in 200  hours have been achieved.   Strains of the present invention have increased sensitivity to iron inhibition of flavinogenesis and have enhanced riboflavin  produc-tion  per  cell at increased iron concentrations in the fermentation medium.   The invention also  is  directed toward  a process for selecting improved microorganisms which are resistant to inhibition of growth by depleted medium.   Such selected mircoorganisms are then  tested for  riboflavin overproduction.   The present invention is also directed toward a selection  process  in  which mutated  microorganisms are cultured in the presence of tubercidin, a purine analog.   Mutant strains resistant to  tubercidin  are  then  tested  for riboflavin over-production.   The present  invention  also  includes  a process  for  producing riboflavin by culturing strains of riboflavin overproducing microorganisms in a fermen-tation medium.   Increased riboflavin production can be obtained   by   elevated  iron  concentrations  in  the nutrient medium.   The fermentation  is  conducted  and after  cell growth levels off,  riboflavin is recovered from the fermentation medium.
