Abstract: A naso-gastric tube (10) or an adapter for an intubation tube is coated in a transparent section (16) with a pH sensitive coating (14) which changes color in response to the passage of gastric fluids from the stomach of a patient (13). Initially, the coating (14) may be made with a red color provided by Congo Red which, upon passage of gastric fluids, changes to a blue color. The naso-gastric tube (10) can be dipped into a solution containing a pH indicator and thereafter dried and cured so as to bond the coating (14) within the tube (10).

Abstract: The invention relates to an ignition device for a propulsive charge of ammunition (3) fired from a weapon (1), the device consisting of an alternating-voltage generator (10) feeding an ignition circuit comprising one or more capacitors and an electrical proximity switch (6). At least one of the electrical connections between the proximity switch and the generator consists of a capacitor (4), called a junction capacitor, one armature (4b) of which belongs to the ammunition (3) and the other armature (4a) of which is fixed to the weapon (1). The frequency of the alternating voltage supplied by the generator (10) is the resonant frequency of the ignition circuit. One of the terminals of the proximity switch is connected to a surface deposit of conductive material (7) applied to all or part of the outer surface of the propulsive charge. The invention is used in the artillery sector. <IMAGE>

Title: Verfahren zur Herstellung von cis-2,6-Dimethylmorpholin
Inventor: BORSDORFF HORST WOLFRAM DR
IPC: C07D265/30
Filed: 1988-01-20
Abstract: Cis-2,6-Dimethylmorpholin wird durch katalytische Isomerisierung von trans-2,6-Dimethylmorpholin hergestellt. Als Katalysatoren werden einerseits Schwefelsäure und zum anderen Edelmetalle, wie z. B. Palladium, Platin, Ruthenium und Rhodium, auch zum Teil im Gemisch mit anderen Metallen wie Zink, Cadmium und Mangan, eingesetzt. Nachteil des Verfahrens mit Schwefelsäure als Katalysator ist eine erhöhte Nebenproduktbildung sowie der Zwangsanfall an Alkalisulfaten, bei den Verfahren mit Edelmetallkatalysatoren der hohe Preis derselben. Der neue Katalysator soll wirtschaftlicher herstellbar sein und noch bessere Ausbeuten ermöglichen. Es wird ein vorher mittels Wasserstoff aktivierter Kupferchromit-Katalysator, der vorzugsweise zusätzlich Bariumoxid und/oder Mangandioxid enthält, zur katalytischen Isomerisierung von trans-2,6-Dimethylmorpholin verwendet. Das Verfahren arbeitet bei Temperaturen von 180 bis 300 °C und bei Drücken von 1 bis 500 bar abs. Mit diesem preisgünstigen Katalysator werden Umsatzraten erzielt, die über denen der bekannten Verfahren liegen.

Abstract: The invention relates to a power amplifier for amplifying analog input signals, which is constructed of N switched-mode amplifiers (V1-VN), which are connected in series at the output end, and a subsequent low-pass filter (FL, FC). The switched-mode amplifiers are implemented as switched-mode amplifiers which are switched on the secondary side and are driven by pulse-duration-modulated pulse sequences (UST1, USTN) which are derived from the input signal (UNF) to be amplified and which are in each case phase shifted with respect to one another by 360 DEG /N. In these switched-mode amplifiers, the mains transformer (TR) handles the DC isolation of switched-mode amplifier output and feed voltage input. <IMAGE>

Abstract: In a brake valve for motor vehicles, an equalising device for at least two brake-system circuits fed with compressed air is provided; this equalising device comprises a stop element (49) which can be stressed mechanically counter to the force of a spring (51) and is supported by a piston (25) which can be stressed by the pressure discharged by the first circuit and acts on the valve system of the second circuit. The spring (51) bracing the stop element (49) is supported against a supporting ring (53) which is supported inside the piston (25) and the relative position of which within the piston can be adjusted when there is thread engagement with an internal thread of the piston. A spring element (57) or similar bracing element which is likewise in engagement with this internal thread of the piston and which expands against the flanks of the internal thread has an effect in relation to the supporting ring (53) such that, upon rotation, the spring element (57) screws up the supporting ring (53) within the internal thread (55) of the piston and, in the unactuated position, secures the supporting ring in relation to the internal thread by expansion. <IMAGE>
