Title: Storable, granulated ammonium sulphate fertiliser prepn. - by adding of a urea deriv. to crystalline ammonium sulphate
Inventor: ERMISCHER WOLFGANG DR
IPC: C01C1/24
Filed: 1991-08-09
Abstract: Prepn. of granulated ammonium sulphate with improved storage-, transport- and spreading properties by compacting, with addn. of pressing auxiliaries or binding agents, comprises addn. of 1-5 wt.% of a urea deriv. to crystalline ammonium sulphate. USE/ADVANTAGE - The prod. is useful as a fertiliser in agriculture and forestry. It is produced as a by-prod. in prodn. of, e.g., caprolactam and acrylonitrile or in gas purifcn..

Title: Testing vacuum of enclosed switchgear - measuring emission current or detecting x=ray radiation before and after capacitive arc discharge
Inventor: FRONTZEK FRANZ DR ING
IPC: G01R31/25
Filed: 1992-02-10
Abstract: The method of testing the condition of the vacuum chamber (13) of an electric vacuum switch or circuit breaker is based on the measurement (32) of the emission current or x-ray radiation (35, 34) between the fixed and moving contacts when partially separated and subjected to a DC or AC test voltage (28). A second measurement (32) of the emission is undertaken after initiating a high power oscillatory arc between the contacts (14, 15) via the charged capacitor (22), inductor (23) and switch (24) for a time determined by the capacitor (2) discharge. The increased level of emission observable after the arc is extinguished enables the vacuum pressure in the chamber (13) to be evaluated from a known relationship. ADVANTAGE - Enables in situ equipment to be periodically checked for efficiency by observing change in emission characteristics after conditioning of contacts, i.e. removal of gas inclusions and contact surfaces by arc. Is equally applicable to arc suppressant, e.g. silicon hexafluoride gas switches.

Title: Electrical blocking device for telephone subscriber's appts. - has polarity reversing component allowing outgoing call connections to be blocked electrically while still allowing incoming call connections
Inventor: KONOPKA PETER DIPL ING
IPC: H04M1/67
Filed: 1992-10-30
Abstract: Appts. (1) has a line input and output to, e.g. a telephone or other telecommunication terminal (T). Between its input and output, the appts. has a polarity reversal component (VS), a lock switch (SS) and a cell detecting setting (S) and resetting (RS) switch.

When the lock switch (SS) is open (position S) outgoing connections are blocked but incoming connections are not. The appts. (1) is bilingual for multi-frequency and pulsed dialling. A call suppressor (WU) is integrated in the appts. (1). When the switch (SS) is locked (position S), dial numbers (MFV or IWV) from the telephone (T) are suppressed and the dial tone can be heard by the user at the telephone, while the suppressor (WU) is by-passed by incoming calls. ADVANTAGE - User hears dial tone when outgoing calls are blocked so he realises that line is not dead.

Title: Push-type trolley, in particular luggage trolley
Inventor: SCHORNSTEIN AXEL
IPC: B62B5/04
Filed: 1993-02-18
Abstract: The invention relates to a trolley, in particular a luggage trolley, which comprises a frame, which surrounds a loading area and is supported on the ground via a front steering castor and two rear fixed castors, and a pushbar, which is supported by means of struts, which are connected to the frame and protrude upwards above the fixed castors. Each of the two fixed castors is provided with a brake which automatically engages under a spring load and, by means of a suitable transmission means which is stiff in compression, can be released manually by a corresponding adjustment of the pushbar. In order to eliminate the disadvantages resulting from the locked braking, which can only be released manually, it is proposed that the brakes be designed as disc brakes and that in addition to the brake actuation, which controls the manual release of the brakes, a device be connected which releases the brakes as a function of a pushing force engaging, in particular in a jolt-like manner, on the trolley. <IMAGE>
