Title: Device and method for supervising the air pressure of a vehicle tyre
IPC: B60C23/04
Filed: 1987-10-08
Abstract: A device for monitoring the air pressure in a pneumatic tyre carried on the rim of a vehicle wheel having a sensor element mounted on the ring of the rim and able to be subjected to and deformed by the tyre pressure, which has a permanent magnet as its transducer in whose sphere of rotation is a measured value sensor, fixed stationarily on the vehicle and connected to an analysing circuit, should function reliably and be of uncomplicated design. To this end the sensor element is designed as a bellows (36) and fitted roughly axially parallel to the direction of movement and at the same time connected to the permanent magnet (40) sliding on a parallel axis on the outside of the tyre as a function of the tyre pressure, the magnet remaining close to the measured value sensor (5) at normal tyre pressure (P) with a greater distance between them at reduced tyre pressure. In addition the bellows (36) should project from a surface-mounted housing on the ring of the rim (21) into the tyre air chamber (25) and be connected via an axial rod or the like to a bistable rocker which can move an axially parallel-mounted permanent magnet. <IMAGE>

IPC: C09K17/40
Filed: 1987-07-08
Abstract: Es wird ein körniges bzw. granulatartiges Bodenver­
besserungsmittel vorgestellt. Die Körner bestehen 
aus speziell aufgearbeitetem Ton und in die Körner 
sind als feste Bestandteile Partikel von Rindenhumus, 
Kalksplit und Hilfsstoffen eingebunden.  
     Durch die Körner wird eine innigliche Verbindung 
zwischen Ton und Humus geschaffen, wie sie in der 
Natur ursprünglich nicht vorkommt. Diese innigliche 
Verbindung beschleunigt beim Einbringen in den Erd­
boden die Bildung des Ton-Humus-Komplexes, weil durch 
die direkte Verbindung von Ton und Humus die mecha­
nische bzw. physikalische Stufe des Ton-Humus-Kom­
plexes ersetzt wird, wodurch eine Bodenregenerierung 
in vergleichsweise kurzer Zeit möglich ist.

Title: Pipe connector and method of applying same
IPC: B21D39/04
Filed: 1988-01-11
Abstract: Disclosed are an improved repair connector 12 for a subsea tubular member 10 and the method of making such repair. The improved repair connector includes an annular housing 18 and an annular guide 16, the annular housing having internal grooves 32 filled with pressure compensating material, a concave recess 36 having serrations therein, a rib 26 having a downwardly facing shoulder on the interior of said housing, and threads 24 on the upper interior of said housing for receiving a string. Means 22 are carried by the guide for sealing against the exterior of a string on which the connector is to be installed. Also, a band of brittle material 42 is positioned within a groove 40 in the exterior of the housing which generates a noise upon the deformation of the housing responsive to completion of the forming of the tubular member therein. The method of connecting the improved connector includes the steps of preparing the casing at a level below the defect, lowering the improved connector into engagement with the upper end of the prepared casing within the well bore, exerting deforming pressure within the upper end of the casing to deform the casing into sealing engagement within the internal grooves in the connector, and releasing and recovering the means generating the deforming pressure.

IPC: C08G65/20
Filed: 1988-02-25
Abstract: The double metal cyanide complex, e.g. metal hexacyano­
metallate, catalysts obtained by reacting metal salts and alkali metal 
cyanometallates are not easily separated from the reaction mixture because 
the particle size is too small to allow filtration under normal conditions. 
Centrifugation, dialysis, or conversion to a filterable metal hydroxide 
salt are the methods previously described for separating the alkali 
metal salt formed during reaction from the catalyst. Forming the complex 
in the presence of an inert filter-aid has been found to give a filter­
able catalyst which can be washed clean of the alkali metal salt and 
can be used without further treatment in the catalysis of the formation 
of propylene oxide polyols.

Title: Communication system with terminals having features determined and controlled by the communication link
IPC: H04Q3/545
Filed: 1989-07-10
Abstract: A parameter-controlled program which is identical for all terminals which can be connected to a communication system is in each case stored in the program memory of the terminals. This program implements all functions which can be allocated to the different terminal types. The functions provided for the respective terminal are allocated and controlled by parameter data stored in a data memory. The parameter data are initially transmitted by the communication system to the respective terminal, or updated, on the basis of an initialisation in the terminal or in the communication system. In a communication system designed in this manner, the terminal-individual flexible allocation of functions and procedures to the respective terminals is retained despite the movement of switching and operating functions into the terminal - which means a dynamic relief of the centralised control of the communication system.

IPC: H04N7/03
Filed: 1989-09-29
Abstract: In a teletext decoder, the digital codes for a requested page 
are acquired and stored in the page memory each time the page 
occurs in the recurrent teletext transmission cycle. This means 
that the stored digital codes are over-written in the page memory 
on each occurrence of the page. Where an acquired digital code has 
been changed for a different code in the decoder so as to display a 
special character, this different code has hitherto been 
over-written periodically by the original code, giving rise to a 
flicker in the display at the character position concerned. The 
present invention prevents this flicker by arranging the decoder to 
look at each stored digital code before it is over-written, and 
preventing the over-writing from occurring when the digital code 
pertains to a special character.

Title: Method for obtaining load-following capability in natural circulation boiling water reactors
IPC: G21D3/12
Filed: 1990-06-12
Abstract: The present invention discloses an improved methodology 
for achieving the desirable feature of recirculation flow control 
in a natural-circulation BWR, enabling reactors utilizing the 
method to perform in load-following modes of power 
operations. In its broadest aspects, the method is based on 
shunting (36,38) adjustable amounts of coolant from the downcomer 
region (17) or core annulus region of a natural-circulation BWR to 
the core upper plenum region (26). This coolant thereby by-passes 
the portion of the ordinary natural--circulation flow path that 
would take the coolant down to the bottom of the reactor 
where it flows into a plenum (22) underneath the nuclear core (24) and 
thence (for the substantial majority of such coolant) flows 
upward through fuel assemblies and only then into the core 
upper plenum region. The key effect of such shunting/by-­
passing is to reduce the differential hydrostatic head available 
for circulating coolant through this latter flow path, i.e. 
through the fuel assemblies, and the rate of coolant flow along 
this flow path thus diminishes in accordance with the arnount of 
flow hydrostatic head reduction in accordance with well-known 
principles.
