Title: Expansion peg
IPC: F16B13/06
Filed: 1988-08-08
Abstract: An expansion dowel is proposed which has an expansion cone (4) which can be drawn into an expansion sleeve (5), a sliding sleeve (8) of plastic or the like being arranged, according to the invention, between the expansion cone (4) and the expansion sleeve (5). During the expansion process, a part of the sliding sleeve material is crushed by the expansion sleeve (5) over the cone surface of the expansion cone (4), so that the pores of the metallic surfaces of the expansion cone (4) and of the expansion sleeve (5) abutting onto one another are clogged by the material of the sliding sleeve (8). In this way, good sliding characteristics are achieved between the expansion sleeve (5) and the expansion cone (4), and a correspondingly good subsequent expansion capability.

Abstract: PCT No. PCT/EP93/03142 Sec. 371 Date Jul. 10, 1995 Sec. 102(e) Date Jul. 10, 1995 PCT Filed Nov. 10, 1993 PCT Pub. No. WO94/11461 PCT Pub. Date May 26, 1994A method is described, using a polyurethane resin mixture, for sealing off points through which water enters geological rock formations. The method utilizes an isocyanate component (a) and a polyol component (b), to be intimately mixed in a static mixer. The mixture is introduced under pressure into the rock formation through boreholes or injection lances. Primary or secondary di or polyamines are substituted for a portion of the polyol component (b) in quantities such that the polyol remains in excess. These amines greatly accelerate the gelation time for the resin, resulting in an instantaneous increase in viscosity of the gel.

Title: Method of making a pocket in a piece of knitted clothing
Inventor: NILSSON EIVOR
IPC: D04B1/24
Filed: 1995-07-31
Abstract: A method for producing one or more pockets (13) in a knitted ready-made garment. The method comprises knitting a piece of tricot (10) having a rectangular configuration with two long sides (11) and two short sides (12). The piece of tricot is folded in at least two places, substantially in parallel with the short sides for forming the back- and side parts of the garment. The remaining parts of the tricot piece at the short sides form a divided front and an arm opening is made at each side part of the tricot piece. The tricot piece is knitted with needles in single bed or double bed or in a combination of those beds, up to a point where a pocket (13) is to be located. A segment corresponding to the two sides of the pocket is knitted in a single bed. The remaining part of the tricot piece is finished by knitting in single or double bed or in a combination of this and the two sides of each pocket are stitched together by seams.

Title: Method for regulating aeration during waste water biological treatment
Inventor: LEFEVRE FANNY
IPC: C02F3/00
Filed: 1999-05-31
Abstract: A process is disclosed for regulating the aeration in a biological wastewater treatment plant using a carbon removal stage, a nitrification stage and a denitrification stage. The process includes the step of continuously measuring the value of oxidation-reduction potential of the treated medium as well as measuring oxygen concentration of the treated medium during aeration phases. This permits maintaining aeration if the oxygen concentration falls within a preselected reference range. Alternately there is reduction of the aeration if the oxygen concentration is above the preselected reference range, or increasing the aeration if the oxygen concentration falls below the preselected reference range. The process requires comparing the oxygen concentration in the treated medium with the preselected reference range during a transition of the oxidation-reduction potential (partial nitrification/total nitrification); and adjusting the reference range of oxygen concentration to a new set of values to correct the oxygen concentration toward a preselected desired level.

Title: Method for routing telephone calls and/or addressed data files which are transmitted via local or global networks
Inventor: JURCZYK-CLEMENS EWA
IPC: H04M3/54
Filed: 2000-02-03
Abstract: The invention relates to a method for routing telephone calls and/or addressed data files which are electronically transmitted via local or global networks. According to the invention the call numbers of several receiving terminals are memorized under a single identification number and incoming telephone calls and data files whose address contains said identification number as destination number are routed to at least one receiving terminal whose call number is memorized under said identification number. According to the invention each memory location for a call number is permanently assigned to a key of the keyboard of a telephone equipped for digital data transmission or dual-tone multi-frequency dialing. The sequence in which the keys are actuated after activation by means of an input code defines a call routing sequence for access to the memory locations. The input of the call routing sequence is memorized and terminated by pressing a telephone key which triggers a limiting signal. If a telephone call or data file is received under the identification number the memory locations are interrogated in accordance with the defined call routing sequence and said telephone call or data file is routed to the call number memorized in the corresponding memory location.
