Patent DK-164312-C (DK)
Inventor: HYLDIG JENS MARTIN HOVMOELLER
IPC: B23D55/08
Filed: 1990-02-20
Granted: 1992-11-02
Abstract: In order to guide a cutting band in a band saw machine in a more efficient manner one or two pivotal band guides (1) according to the invention are fitted as close as possible to the cutting place. Each guide (1) is in two parts and designed as a wheel which can run on bearings (5). The wheel consists of two guide rings (2, 3) with side faces (10) forming lateral guides for the side faces of the saw blade (17) or the knife blade (11). At the rear the cutting blade is provided with a bottom guide in the form of a face (13, 19). This may be configured as the periphery of the rings (12, 18, 21). Finally, one or a number of tolerance rings (14, 20) are inserted, permitting adjustment of the distance between the sides faces (10) on a continuous basis. Hereby is obtained a rotary guide (1) which is not exposed to irregular wear since the entire guide is easily brought to rotate when the cutting blade is moved. This gives a hitherto unobtainable good guiding since the cutting band is being guided in all directions of tension during cutting, whereby deformation of the band is avoided. This gives a very accurate guiding without noise and with reduced wear of the cutting band.

Granted: 1991-03-19
Abstract: ABSTRACT OF THE DISCLOSURE     METHOD AND APPARATUS FOR PRODUCING     FOLDED OPTICAL PATH DEVICES           Disclosed is a method and apparatus for the lowcost assembly of precision optical devices utilizing single or multiple bounces.  The apparatus makes use of a precision machined alignment platform to support optical mirrors in precise alignment.  A low cost holding structure is clamped over the alignment platform to position one of a plurality of connected sections adjacent to the back of each mirror.  An adhesive is injected through holes provided in the holding structure adjacent to the back of each mirror.         The adhesive bridges each mirror to the holding structure in a position corresponding exactly to the position of the mirrors on the alignment platform, thereby eliminating any need to adjust the mirrors for correct alignment.

Granted: 1990-12-11
Abstract: ABSTRACT OF THE DISCLOSURE    A slide fastener includes a row of coupling elements secured by sewing stitches to one longitudinal edge of a support tape made of film of plastics material, a non-woven fabric or a thread-free web.  The sewing stitches are formed of at least one thread having loops passing through the support tape.  The thread is a monofilament.  When the fastener of the present invention is subjected to heat-set treatment, the monofilament resists the tendency of multifilamentary threads to flatten out.          Consequently, the slide fastener of the present invention provides, after heat-set treatment an improved mechanical strength at the connection between the sewing stitches and the row of coupling elements.

Abstract: Abstract:      For use in a hot wire air flow meter, a platinum wire is coiled and coated with a glass material.  Its ends are welded to support members to form an exothermic resistor with no bobbin therein.  One such bobbin-free resistor is used as a hot wire element and another is used as a cold wire element in the meter.  The heat generated in the coiled wire is almost entirely carried away through the air.  In this way the transient response characteristics upon a sudden change of the amount of air flow can be improved.

Abstract: PEROXIDE BLEACHING OF MECHANICAL PULPS                  ABSTRACT OF THE DISCLOSURE           A process for peroxide bleaching of mechanical pulps by washing the pulp to remove substantially all of the heavy metal ions from the pulp, mixing hydrogen per-oxide in an amount of at least about 1-1/2% based on the dry weight of the pulp with the washed pulp to uniformly disperse the hydrogen peroxide throughout the pulp follow-ed by mixing an aqueous solution of sodium hydroxide with the pulp containing hydrogen peroxide to uniformly distri-bute the sodium hydroxide throughout the pulp and to react the  sodium  hydroxide  with  the  peroxide  to  produce perhydroxyl ions in situ in the pulp and then reacting the perhydroxyl  ions with the pulp to increase the brightness of the pulp and provide a residual  peroxide of at least 35% of the peroxide added. This system provides a signif-icant  increase  in  residual  brightening  chemical  in  the residual liquor separated from the brightened pulp.  In a preferred  process  to  utilize  this  residual  brightening chemicals,  the washed pulp is divided into two portions and the hydrogen peroxide is added to one portion as above described, following reaction of the perhydroxyl ions with the pulp of the one portion the so brightened pulp portion is  separated from a residual  liquor containing residual brightening chemicals.   This  residual  liquor  containing the residual brightening chemicals is uniformly mixed with the second portion of the pulp followed by dispersion of caustic through the second  portion to cause reaction of the residual brightening chemicals with the second portion of the pulp to brighten the second portion of the pulp.

Title: Formation of electric field discharges

IPC: F02P9/00
Filed: 1987-12-18
Granted: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE          An  ignition system for hydrocarbon fuels based on a new approach to ignition in which the principle of "flame discharge ignition" is introduced to couple ignition energy to the initial flame front plasma (32) to convert the flame front (31) into an ignition dis-charge  in which electrical energy is efficiently coupled to  the propagating  flame front,  either as a "pulsing  flame  discharge ignition"  system  in which the flame front becomes part  of  the spark  discharge circuit,  or an "enhanced conventional discharge ignition" in which very high electric fields are "naturally" main-tained at the flame front.   Electrical,  geometrical, spark, and hydrocarbon flame front plasma discharge properties are taken into account  and adjusted or tailored,  where practical,  within  the context of the new approach,  to create a flame discharge process capable  of igniting very lean mixtures.  The system  is  further improved by modifying the fuel's flame front plasma properties by increasing  the ratio of the Carbon to Hydrogen (C/H) content  of the  fuel so that the C/H ratio falls in the range of 0.5 to 2,0, and/or  by  using additives to further increase the  flame  front plasma  density  (35) without reducing the  plasma  recombination coefficient,  and  preferably raising it by at least  eliminating lead additives.   Such improved hydrocarbon fuel is usable in all types  of IC engines and burners including systems using electro-magnetic combustion support means for maintaining a high electric field  of  the order of 1000 volts/cm/atmosphere at the  fuel-air flame front for enhancing combustion reactions,  especially under lean air-fuel ratio for the lowest exhaust emissions (low NOx) and highest combustion and engine efficiency.
