Title: Installation for central control unit for watchman - comprises several portable units with recognition code words activated by mobile unit on arrival at each post
Inventor: LOCHER ROBERT
IPC: G07C1/20
Filed: 1980-06-07
Abstract: The installation consists of a desired number of watchman's posts situated away from the central control and in the areas to be supervised (11.1), (11.2), they operate passively and have no electrical connections or installations. However, they all possess a memory (12) for a respective individual codeword as well as a trigger (13) for triggering the mobile units (20). Each watchman (17) carries an issued mobile unit (20) with him on his round, which at a given time, he inserts into the aperture of the post (11) where he is located. The trigger (13) activates and initiates the function of the mobile unit (20) which reads the location codeword of the watch post (11) and stores it. The unit (20) then transmits the stored codeword to the central control station (30), which prints it together with the time. This ensures a continuous record for instance, in industrial premises.

Title: Fungicidal tri:morfamide prodn. - by reaction of morpholine with 1,2,2,2-tetra:chloro-ethyl-formamide in an aq. two=phase system
Inventor: URBACH HANS DIPL CHEM DR
IPC: C07D295/13
Filed: 1980-06-07
Abstract: In the prodn. of N-(1-formamide-2,2,2-trichloroethyl) morpholine (I) by reaction of 1,2,2,2-tetrachloroethyl formamide (II) with morpholine, the reaction is carried out at -2 to ca 60 deg.C and at pH 3-14 in a 2-phase system one phase of which is water. (I) is the known fungicide trimorfamide. Carrying out the reaction in a 2-phase system gives improved yields of (I) (ca 90% or, in the presence of a phase-transfer catalyst, up to 97%). Despite the known sensitivity of (II) to water, the reaction is carried out in an aqueous 2-phase system without marked hydrolysis. The reaction is pref. carried out at a pH of greater than 7 by adding alkaline cpds. The reaction is advantageously carried out in the presence of a phase-transfer catalyst.

Title: Supervising remote controlled switching of load - by alternating signal which if disturbed causes trip to safe state
Inventor: BOSCHULTE RAINER ING GRAD
IPC: G08G1/097
Filed: 1980-06-12
Abstract: Process instructions are sent in digital form from a central controller and received by the local unit (AS). The most important signal, for example that for connecting the local power supply to the process, is sent continuously in alternating form so that any disturbance or failure in the data transmission link will trip the local process to a safe state.S The incoming alternating information is applied to logic circuits (UB1,UB2,UG3,OG) and counter (ZE1) which, with receipt of the correct and symmetrical sequence give a constant output to a solid state switch (S2). The latter keeps the circuit of a relay (RB) energised. Before this relay can respond initially an auxiliary relay (RA), with close and hold coils, must be activated by a single logic signal (J1). Its hold on coil (2) is in series with a contact (RB2) of the main relay (RB). If there is a transmission fault, or a switch off instruction, the switch (S2) in the main relay circuit opens. The relay drops off and is followed by the auxiliary relay. The supply to the process is thus interrupted (RA4,RB5). It cannot be restored without a specific close instruction to the auxiliary relay, even if the alternating signal is subsequently restored.

Title: Dry coke quenching system - preceded by screening in two or three size ranges for separate bolting chambers
Inventor: STRUCK CARL-HEINZ DIPL CHEM DR
IPC: C10B39/02
Filed: 1980-08-16
Abstract: A dry quenching system for hot coke from the chambers of a coke oven battery is based on direct or indirect contact of the coke with a coolant fluid. Before entering the cooling chamber, the coke is pre-screened into two or three size ranges which are treated in separate sections of the cooling chamber. Two ranges would pref. consist of the 0-80 mm and the over 80 mm sizes, and three of the 0-20 mm, 20-80 mm and over 80 mm sizes. This results in a more uniform distribution both of the flow through the coke and of the temp., so that the residence time in the cooling chamber is not governed any more by the slower cooling rate of the oversize.

Title: Radial-piston machine, in particular spherical-piston pump
Inventor: BUDECKER L
IPC: F04B1/107
Filed: 1981-05-29
Abstract: In a radial-piston machine, in particular a spherical-piston pump, an outer stator and an inner rotor are provided which is rotatable on a control journal provided with inflow and outflow ducts. The rotor has at least one radial bore in which a spherical piston, consisting of an outer sphere and an inner cylindrical sleeve can be displaced. The sleeve is designed to be comparatively massive, with an inner axial passage. Sphere and sleeve are not tied to one another and can be replaced individually. Integrally inserted in the radially outer end of the sleeve there may be an annular sliding body made of a low-friction and sound-insulating material, which body is in a sealing engagement along a linear contact with the sphere. Thus, in addition to good areal sealing between the sleeve and the rotor, good sealing both between the sleeve and the sliding body, respectively, and the sphere is achieved, the latter being improved owing to the comparatively high centrifugal force of the massive sleeve. This results in good volumetric efficiency even at high pressures.
