Title: Sterilisation appts. for medical flasks - with controlled cooling section air circulation to heating section
Inventor: SIEDLER HORST
IPC: B65B55/02
Filed: 1991-09-17
Abstract: In the appts., ware is conveyed on a common transport belt through a heating section and then a cooling section employing a Hosch-filtered low particle content air stream which is directed onto the ware transversely to the transport direction and then passed into the heating section for circulation over the ware. The novelty is that the circulated air temp., measured at a temp. sensor (8), is regulated in accordance with the air exhaust power of a ventilator (4) in the cooling section, the pressure in a connection channel (12) being held constant by power increase of the circulation fan (13). The temp. sensor (8) controls a flap by means of a flap adjustment motor (5) and thus modifies the air transport power of the air exhaust ventilator in the cooling zone. USE/ADVANTAGE - The appts. is used to sterilise flasks for parenteral drugs and has improved energy balance.

Title: Biodegradable carboxy-alkane-aminomethane-phosphonic acid mixt. used as metal ion chelating agent - consists of amino:bis(methylene phosphonic) acids and small amts. of amino:mono(methylene phosphonic) acids
Inventor: SOMMER KLAUS PROF DR
IPC: C07F9/38
Filed: 1991-09-25
Abstract: Carboxyalkane-aminomethanephosphonic acid mixt. (I) consists mainly of aminobis(methylenephosphonic) acids HOOC-CHR-N(CH2PO3)2)2 (II) with small amts. of aminomono(methylenephosphonic) acids HOOC-CHR-NH-CH2-PO3H2 (III). In the formulae R is H, alkyl, aralkyl or substd. alkyl gps., as present in the side chains of natural aminocarboxylic acids. (I) is prepd. by reacting proteins or their partial hydrolysates with HCHO and H3PO3 in the presence of a little amt. of HCl or PCl3 in aq. medium at 80-120 deg.C, pref. at the b.pt., using a molar ratio of HCHO/H3PO3 or PCl3/aminoacid units of 2.2:2:1. Waste, e.g. scraps of leather, wool and silk waste, gelatin or casein, is used as protein. USE/ADVANTAGE - (I) is used as chelating agents for polyvalent metal ions and for stabilising water hardness in less than stoichiometric amts. It is useful for masking metal ions, e.g. in the textile, paper and photographic sectors, and for water treatment, esp. to inhibit boiler scale formation. The chelating power and threshold effect are similar to those of commercially available aminomethanephosphonic acids (IV) and aminotrismethylenephosphonic acids (V), whilst the Fe binding power is slightly higher than that of (V). Unlike (IV), (I) can be eliminated in conventional biological sewage plants and used in textile finishing processes without decomposing metal complex reactive and direct dyestuffs.

Title: Navigation method for vehicle - determines actual distance covered by vehicle and alteration in its actual travel course to compute actual route covered
IPC: G05D1/02
Filed: 1992-03-24
Abstract: The navigation system compares the actual route covered with a predetermined travel course, and matches a running actual to a corresp. vehicle position in the predetermined travel course. A deviation (d) of an actual position (O') from a position (O) in the predetermined travel course, at which the navigation system has detected the alteration of the actual route covered is computed. The position (O) is predetermined as a position, for altering the predetermined travel course, if the navigation system detects the altteration in the actual route covered. The determined actual position (O') is caused to coincide with the predetermined position (O) in the predetermined travel course, and the computing of a following coupling course follows, if the computed deviation (d) lies with a limiting value (D1,D2,D3). A point (A1,A2,A3) is found on the predetermined travel course (X) and a point (B1,B2,B3) on an extension of the actual route (Y) covered, respectively at a predetermined straight stretch (L1,L2,L3) remote from the predetermined position (O), which represents the origin (O) of the computation. An angle is determined at the origin (O), between two points (A1,B1,...A3,B3) on the extension of the actual route (Y) covered and the predetermined course (X) if the deviation (d) exceeds the limit value (D1,D2,D3), and causes the point (A1,A2,A3) in the predetermined course (X), and continues the computing of a second coupling course to follow on, if the angle lies within a predetermined angular value. USE/ADVANTAGE - Navigation method and system of given type designed to give improved matching of actual route covered by vehicle to predetermined route.

Inventor: KIKUCHI MASAMICHI
IPC: G08C25/02
Filed: 1992-04-11
Abstract: During data transmission between a receiver and each of a plurality of terminal devices (Q1Qn) in a disaster prevention supervisory system, the receiver sends calling data including address data for specifying a specific terminal device to the side of the terminal devices in a transmission error detection mode. The receiver also causes the terminal device specified by the address data to return error detection response data including self-address data and check data at a current level previously defined. When the current level (6) of the check data in the error detection response data received by the receiver is higher than the level previously defined due to the response of a plurality of terminal devices, it is decided that an abnormality is present in the terminal device of the address specified by the calling data. <IMAGE>

Inventor: LANG GERHARD
IPC: G01F1/08
Filed: 1992-06-06
Abstract: The subject of the invention is fluid meters having an impeller, especially water meters installed vertically. In order to reduce the bearing friction and increase the measuring sensitivity, the specific weights of the impeller (10), of the wheels (32, 33, 34) of the reduction gear and/or the counter (35) are initially matched to the specific weight of the measuring fluid. Furthermore, the centres of gravity of the impeller (10), the wheels (32, 33, 34) of the reduction gear and/or the counter (35) are set exactly in the middle between the respective bearing points. This purpose is served, for example, by closed cavities (41) increasing the positive lift or additional weights (40) increasing the negative lift. In order to set the centre of gravity, these can be displaced along the shaft (11) of the impeller (10) or the shafts of the wheels (32, 33, 34) of the reduction gear or the counter (35). <IMAGE>

Patent DE-4220414-A1 (DE)
Inventor: CEZANNE RUDOLF DIPL ING
IPC: B60T8/26
Filed: 1992-06-22
Abstract: In order to prevent a twin brake pressure regulator with a control plunger and a balance arm from exercising its pressure attenuating function by means of an electromagnetic locking device, and to avoid high costs and material expenditure, the electric coil (18), together with the cutout blade (17) and the locking member (16) secured thereto, is radially arranged with respect to the regulating piston (3), and the locking member (16) is interlocked with the control plunger (13). Preferably a U-shaped fork whose inner diameter is adapted to the control plunger is arranged for that purpose on the locking member (16). In an appropriate manner, the extended position, i.e. the position in which the locking member (16) locks the control plunger (13), is defined by the position of the cutout blade (17) when the coil (18) is energized, whereas the retracted position of the locking member (16), in which the control plunger (13) is released, results from moving back the cutcout blade (17) when the coil (18) is without current. This twin brake pressure regulator is thus suitable for use in antilock braking systems, in which the pressure attenuating function is suspended as long as the antilock function can be exercised, and only comes into operation when the antilock function is suspended.
