Abstract: Bonded fibre mixed yarn (I) has a carrier fibre (II) of wool or its mixts. with other carpet fibres (IIA) and melt bonding fibre(s) (III). Pref. (IIA) is polyamide, polyester, polyacrylonitrile or polyolefin fibre; and (II) contains at least 50 (wt.)% wool. (III) is a melt spun fibre of polyamide, polyester, polyolefins or a blend of these, esp. a copolyamide or copolyester with m.pt. below 150 deg.C. (I) is carded or half-combed yarn and the amts. of (II)/(III) are 98/2 to 80/20%. (I) is bonded at 100-140 deg.C, pref. by steam treatment at 100-130 deg.C and pH 4-8. USE/ADVANTAGE - (I) is used in woven or knitted textiles, pref. wall coverings and carpets with velvet, loop or curled pile, in which (I) pref. is anchored to a base by knotting and pref. also smoothing (claimed). The use of (I) instead of unbonded wool (mixts.) improves the yarn structure retention, esp. in deep pile carpets, and reduces `shading' in velvet carpets. Fixing increases the strength and running properties of the fibres, e.g. in tufting, ensures satisfactory contour sharpness, e.g., on printed velvets and also increases anchoring of the pile.

Patent DE-4312140-A1 (DE)
Inventor: HERB ARMIN
IPC: F16B13/08
Filed: 1993-04-14
Abstract: The fastening element comprises an anchor bolt (1) and an expansion wedge (2), which is provided, in a first end region (6), with a flange-like attachment part (5) for absorbing loads, which attachment part exhibits a through-passage bore (3) for the expansion wedge (2). Arranged in a second end region (7), of the anchor bolt (1), located opposite the first end region (6) is a wedge surface (4) which, towards the free end of the second end region (7), comes closer to the peripheral contour of the anchor bolt (1). In order to expand the fastening element in a prefabricated receiving bore, the expansion wedge (2) is displaced axially with respect to the wedge surface (4) arranged on the anchor bolt (1). In order, before the expansion, to achieve automatic retention of the fastening element in receiving bores, the expansion wedge (2) is designed in the form of an arc, with the result that it bears on the anchor bolt (1) only in the first end region (6) and in the second end region (7). <IMAGE>

Patent DE-4320574-A1 (DE)
Title: Device for handling track functions in electronic signal boxes
Inventor: BROSZINSKI HANS-JUERGEN DIPL I
IPC: B61L21/06
Filed: 1993-06-15
Abstract: Each track-release indication section is preferably assigned a separate track section element (GA1) in the processing logic in the signal box, which track section element (GA1) realises specific track functions for all the associated track elements (W1 to W4). The programs for realising these track functions, predominantly the monitoring of the track in the route system and the release are no longer present in the processing logic of the track elements. The track section elements are placed in the signal box-side track system in such a way that in the simulation of the respective track-release indication section they assume a position which is touched by all possible routes via this track-release indication section. The track section elements (GA1) interact with the adjacent track section elements in order to exchange indications via the logical elements (SW1 to SW4) of their own track section elements and those of the adjacent track section elements, and under appropriate conditions cause track-release codes and reports which are required for the release of track elements to be passed on. They are preferably actively self-releasing and release the track elements assigned to them according to the principle of automatic release. <IMAGE>
Patent DE-4322278-A1 (DE)
Title: Process for producing capillary membrane bundles
Inventor: STEINFORTH ALFRED
IPC: B01D63/02
Filed: 1993-07-05
Abstract: The capillary membranes are attached by this process to strips, e.g. made of paper, in any desired exactly definable mutual spacing. The mats thus produced can be rolled up to form bundles. The fixing of the membranes to strips secures the desired spacing of the membranes to each other when the mats are rolled up. By this means the membranes can be completely distributed in the bundle in any desired manner. This cannot be ensured in the known bundling processes. The process can be used e.g. for the production of capillary membrane bundles for dialysers.
Patent DE-4322830-A1 (DE)
Title: Diamond diode structure
Inventor: BURCHARD BERND
IPC: H01S5/02
Filed: 1993-07-08
Abstract: The invention comprises a method for producing a semiconductor diode which operates as a light-emitting diode or as a laser diode. A diamond substrate - optionally a crystal or a crystalline or polycrystalline film - contains defects which are responsible for active luminescing colour centres (for example H3 centres, A band centres, 484 nm and 886 nm nickel-induced centres, 738 nm silicon-induced centres). Two regions are made on this diamond substrate: the first is an optically transparent semiconducting (p<+> or n<+> type) region which is produced by ion implantation with electrically active impurities, with subsequent annealing and etching, or by deposition of a diamond film in which electrically active doping is introduced during the growth. The other region is a collector which was produced by ion implantation and/or metallisation while maintaining a separation from the seimconducting region which must be larger than the free path of the charge carriers in the diamond substrate. When a voltage is applied between the semiconducting region and the collector region, the structure produced by this method emits green and/or blue and/or red and/or near-infrared light. For the purpose of laser emission, the semiconducting region is produced on a flat working surface which was previously prepared on the diamond substrate by polishing. Two mutually opposite parallel ... are additionally ... Original abstract incomplete. <IMAGE>

Title: Inverter voltage source with resonant primary winding output=transformer - has fet controlled switching of resonant transformer primary and null=point detector triggering pulse generator for fet timing control
Inventor: SAKAMOTO HIROSHI
IPC: H03K17/732
Filed: 1993-10-07
Abstract: An inverter voltage source supplied from a DC source (10) comprises a FET switching element (31) and a transformer (20) with primary (21) and feedback winding (23). The primary (21) and capacitor (25) form a parallel resonant circuit which when resonating energises the load (27) via the secondary (22). A starter circuit (11, 12) across the source (10) provides an initial offset voltage (VB) at the FET (31) gate which switches on to commence a self-excited oscillation in the resonant circuit (21, 25) maintained by the feedback winding (23) and voltage (VG). A null-point detector (60) which triggers a pulse generator (50) employing pulse-width control ensures that the conducting periods of the FET (31) are optimally timed to minimise switching losses. ADVANTAGE - Largely eliminates switching losses of similar FET controlled systems resulting in improved efficiency and stability.
