Inventor: NAUMANN JOACHIM DIPL ING
IPC: C07C217/26
Filed: 1992-03-26
Abstract: Articles are sterilised in a comapartment with 2 doors, by contact with hot vapour of a perfluoro organic cpd., at a temp. of the vapour at least that needed to kill microorganisms. After sterilisation, the article is removed from the door other than that through which it was introduced. The b.pt. of the cpd. is at least, and is close to, the temp. needed to kill microorganisms, or can be raised to such a level by use of pressure. The cpd. is a perfluoropolyether of formula (I), perfluoropolyether of formula R1 -O-A-B-C-R2, a perfluoroamino ether of formula R4R5N-(CF2-O)e-(CF2)f-N R6R7, or a perfluoroalkane of formuala ChF2h+2. In the formulae, m, n = 0-3; R1, R2 = CaF2a+1; a = 1-4; A, B, C = ((CF3)CFCF2-O)b, -(C2F4-O)c or ((R3)CF-O)d ; R3 = F or CF3, b = 1-7, c, d = 0-7; e, f = 1-6; R4 to R7 = CgF2g+1; g = 1-14; and h = 12-20. ADVANTAGE - The sterilising cpds. are thermally and chemically stable, have very low toxicity, volatilise from the articles without residue, and are 99.9% pure, with constant b.pt., giving precise temp. control. Re-infection is avoided by using different entry and outlet point

Title: Low loss semiconductor current-limiting circuit for electric lamps - used NTC thermistor in series with lamp filament mounted in base to compensate resistance and limit switch=on current
IPC: H05B39/02
Filed: 1992-06-10
Abstract: A resistive switching element is used to reduce the current surge when switching on an electric lamp. A n.t.c. thermistor compensates for the low switching resistance of the lamp in series with it (which has a positive temp. coefft.). This increases the lamp life and reduces the electrical loading on the switch. The thermistor resistance when cold has up to seven times the value of the filament resistance. The thermistor is incorporated in the base socket of the lamp. Typically, the switching current surge is reduced by a factor of four. USE/ADVANTAGE - High and low voltage bulbs for use in home, in traffic stop signals and in motor vehicles. Practical and inexpensive extension of lamp life.

Title: Rigid polyurethane foam with improved elasticity and wear resistance - by dissolving a high polymer, pref. polyvinyl butyral, in the poly:ol-di:isocyanate mixt. before foaming
Inventor: BENEKE HERBERT DR
IPC: C08J9/00
Filed: 1992-07-23
Abstract: A process is claimed for the prodn. of polyurethane (PU)-based rigid foam with improved elasticity and abrasion resistance (I), by dissolving a high polymer (II) in the mixt. of polyol and di-isocyanate before foaming. (II) is polyvinyl butyral (PVB), in amts. of 2-30 (pref. 5-15) wt.%. USE/ADVANTAGE - The process enables the prodn. of rigid PU foam with improved elasticity, impact resistance and abrasion resistance. This foam can be stepped on and driven over with heavy vehicles, and also fixed directly with nails and screws, and is therefore suitable for insulating surfaces which are subjected to loads (roofs, tanks, piping, refrigerators, etc.). In an example, 8.7 wt.% PVB was dissolved in a mixt. of 24.65 wt.% polyol contg. 11.5% OH and 24.65 wt.% polyol contg. 3.4% OH, then 42.00 wt.% di-isocyanate (31.5% NCO) was added with stirring, followed by 0.2-0.6 wt.% water as blowing agent. The prod. had density, 160-200 kg/m3 (depending on the amt. of water added); elongation 17-24%; flexural load (20mm deflection) 0.111-0.112 MPa. Corresp. values without PVB were: 182-201 kg/m3, 15.2-15.8%, 0.191-0.202 MPa (some samples fractured before reaching 20mm deflection).

Patent DE-4228392-A1 (DE)
Inventor: PFISTER ROMAN
IPC: E02F9/20
Filed: 1992-08-26
Abstract: The invention relates to a method of controlling the grab bucket of a rope excavator with a boom pivotably linked to a revolving superstructure. To achieve the object of automatically controlling the grab bucket of the rope excavator in such a way that the tolerance for the excavation can be accurately adhered to, the rope length is measured at the winch drum and is corrected by a correction value which takes into account the boom length, the difference between the winch-drum periphery and the periphery of the boom sheave, the offset length from the winch centre point to the jib pivot point, the inclination of the revolving superstructure relative to the normal level, and the boom angle, which is determined by angular measurement at the jib pivot point, in order to determine the effective hook height.

USE/ADVANTAGE - For treating waste water from abattoirs, meat processing plants, etc. The reactor is capable of long term stable operation (even when in the form of a retrofitted reactor), treats the waste water anaerobically on site in a residue-free manner using bacteria immobilised on the substrate material, ensures high biogas yield and avoids the use of enzyme preparations.
Patent DE-4236677-A1 (DE)
Title: Control of combustion air flow in cross-flame furnaces e.g. for melting glass - air flow is slowed or accelerated in burner port or chamber inlet by stream of gas of cross-section equal to or less than that of air flow duct
IPC: C03B5/235
Filed: 1992-10-30
Abstract: In a new procedure for achieving the required distribution of combustion air in regenerative cross-flame furnaces, at least a part of the air flow in the air pre-heater is throttled by an opposing stream of gas. This throttling takes place in an area of relatively high dynamic pressure level such as a flow duct preferably in the form of a burner port or a chamber inlet. The area of the opposing gas stream is approximately equal to, or less than, the cross sectional area of the duct. Also claimed is a procedure for increasing and especially for partially increasing, the velocity of the combustion air in a similar manner but using a stream of air moving in the same direction as the combustion air flow. Also claimed is a device for carrying out the above procedures, in which a gas duct or lance is provided in the air preheater area and has a control device such as a solenoid valve opening towards the combustion chamber. USE/ADVANTAGE - For achieving the required combustion air distribution in cross-flame furnaces such as are used e.g. for melting glass. Modern cross-flame furnaces achieve the required combustion air distribution by the use of separate burner regenerator chambers. This invention allows the disadvantages of a cross-flame.

Patent DE-4313051-A1 (DE)
Inventor: MUELLER GOTTFRIED
IPC: F21V7/00
Filed: 1993-04-21
Abstract: Ceiling luminaires, in particular built-in ceiling luminaires often have to be accessible from below and therefore have a corresponding constructive structure of the luminaire housing. The light source which can be inserted in a main reflector of the luminaire is in this case usually arranged at a socket holder which is mounted on the luminaire housing. In high-quality ceiling luminaires, specific photometric requirements must be met which in particular assume that the focal spot of the light source is arranged at a photometrically specified point with reference to the main-beam axis of the luminaire. In known ceiling luminaires, tolerances in terms of material and production result in this focal spot being repositioned.   To compensate for tolerances of luminaire dimensions, the vertex plane of the main reflector (3) of the luminaire is selected as reference plane. The light source (5), together with its socket (10) and the socket holder (9, 11) is constructed as a unit with narrow tolerances, which is supported directly, preferably movable along the main-beam axis, on the main reflector in this reference plane. This solution can be advantageously used in particular in high-quality ceiling luminaires, in which light-shaping elements, such as diffusing screens, filters and the like, and whose thickness dimensions frequently have large tolerances due to production, are arranged in the light exit opening. <IMAGE>
