Abstract: The invention relates to a procedure for mounting the guide rails for an elevator car or counterweight, wherein the guide rails are attached to an intermediate beam laid across the elevator shaft, said beam being attached at least by one of its ends to opposite walls of the elevator shaft, and to a mounting system implementing the procedure. At least two steel plates (5,6) or equivalent are placed oppositely on the vertical sides of the intermediate beam (2), the upper and lower edges of the plates extending at least somewhat above and below the intermediate beam (2) . The plates (5,6) are pressed against the intermediate beam by means of bolts, threaded bars (7a,7b,8a,8b) or equivalent connecting the plates and passing above and below the intermediate beam so that the plates (5,6) are held in position by the friction generated between the plates and intermediate beam by the pressure, and that the guide rails (11,12) for the elevator car or counterweight and/or their mountings (13,14,15) are secured on the plates (5,6) and/or bolts (7a,7b,8a,8b) in a manner known in itself.

Abstract: In this publication there has been presented a movable roll holder for unwindable material, e.g. towel paper, equipped with a tightener based on a counterweight mechanism. The roll holder includes a foot (1) to which a shaft (2) is attached so that the shaft can easily be removed for changing the roll. It is possible to tear a piece of paper from the roll holder by one hand so that the paper tears off reliably along the perforation and that the paper left in the holder does not run from the roll holder. To the shaft (2) of the roll holder has been mounted a counterweight (3) which pulls a tightener (5) against the paper with constant load. The tightener prevents the paper from running during and after the tearing and thus enables the dosing of the paper by one hand.

Title: Tooth brushes
Inventor: BARMAN ROLF

Granted: 1994-09-20
Abstract: ABSTRACT.       A process for producing a tooth brush (10') with at least three head portions (13, 14, 15), which are mutually separated from each other in pairs by means of an inter-mediate cavity (11, 12). The head portions (13-15) are angled relative to each other about an axis (14a, 15a) parallel to an associated cavity (11, 12) after associated bristle groups (19) are fixed in place and after a local heating of the tooth brush head  is effected. The tooth brush head (lOa) is subjected to a local heating at the bottom (11a,12a) of each of the cavities (11,12), in that a heat conducting means (21) is introduced into each cavity (11, 12) for heating the cavity at the bottom of same. The angling is effected about a respective of said axes (14a, (15a) which are arranged on the bristle-carrying side of the tooth brush head, that is to say just at the bottom (lla, 12a) of the associated cavity (11, 12) A blank for carrying out the process has the cavities (11, 12) arranged on the back side of the tooth brush head, that is to say on the side opposite the bristle-carrying side of the tooth brush head. The longi-tudinal axes (14a, 15a) for angling the head portions (13, 14, 15) relative to each other are arranged on or at the bristle-carrying side of the head portion directly oppo-site the associated cavity (11, 12).     A tooth brush has the cavities (11, 12) arranged on the back side of the tooth brush head. The bristle groups in the middle head portion are terminated in alignment with the bristle groups in the innermost rows of bristle groups of the two outer head portions. The bristle groups of the two outer head portions extend obliquely towards each other in alignment with the bristle groups of the middle head portion.

Title: Fiber optic cannister with compliant baselayer
Inventor: HULDERMAN GEORGE H
IPC: B65H55/00
Filed: 1990-01-30
Granted: 1995-05-09
Abstract: The invention is a compliant material that is used as a baselayer for underlying layers of an optical fiber wound onto a bobbin.  In one embodiment the base-layer is selected for compatibility with an optical fiber coating. In another embodiment, the 10 compliant material comprises a coating disposed on the bobbin.  In another embodiment, the base layer comprises a silicon material.     The use of a compliant material as a baselayer eliminates the need to fabricate and stock expensive 15 baselayer wire material.  Use of the compliant material is also believed to reduce the stresses in the first wound fiber layer.  In addition, it is easier to match the thermal properties of the optical fiber with the thermal properties of the compliant 20  material over a wide temperature range than it is to match the thermal proper-ties of the optical fiber to the baselayer wire.  Thus, over an anticipated operating temperature range, the difference in thermal expansion characteristics between the base layer and 25 the wound fiber are reduced, thereby minimizing the risk that the fiber pack will slip off the bobbin during long storage or payout.

Abstract: A method of forming a composite material by providing a quantity of first particles of a binder material and a quantity of second particles of a primary material having a softening temperature substantially in excess of the softening temperature of the binder material. The first and second quantities of particles are combined into a substantially uniform mixture. The uniform mixture is heated in the absence of pressure or shear sufficient to convert the binder particles, to a temperature substantially above the softening point of the binder material but less than the softening temperature of the primary material. Thereafter, pressure and shear are applied to the heated mixture sufficient substantially immediately to convert at least a portion of the binder material particles into a substantially continuous webbing structure or force the formation of point-bonds. Substantially immediately after formation of the binder particles into this unique structure, the mixture is rapidly cooled to below the softening point of the binder material to retain the converted binder material in its continuous form or forced point-bonded condition. This produces the composite material composed of primary particles, a binder resin phase forming a continuous web matrix or point bonds, and a volume of empty pores. Also disclosed are products formed by the method.

Title: Method of manufacturing printed circuit boards
Inventor: OTT ALBERT
IPC: H05K3/34
Filed: 1990-06-04
Granted: 1995-01-31
Abstract: A method of manufacturing printed circuit boards is disclosed wherein metallic conductive structures are produced in a desired pattern on a carrier board of isolating material.   The method begins with the provision of a carrier board having a metal foil laminated to its surface and thereafter forming conductive traces on the carrier board, deactivating the carrier board to remove substantially all substances deposited on the carrier board other than the conductive traces and forming final conductive structures by  electroless  chemical  metal  deposition  on  the  pattern  of conductive traces.  Circuit boards manufactured in accordance with such a method will have final conductor structures with base layer portions of the original laminated  metal foil.  In a preferred embodiment, the step of deactivating the carrier board involves rinsing the carrier board with hydrochloric acid.  The method can be used  for manufacturing  single-layer or multilayer printed circuit boards with or without through-holes and permits the formation of conductor structures in the range of 50 micrometers or less.
