Inventor: DAVID LAWRENCE DANIEL
IPC: C01B25/26
Filed: 1987-09-22
Abstract: The process for producing microsized amorphous particles of a metal phosphate incorporates the steps of 
forming a solution of a metal alkoxide in an organic solvent, 
forming an aqueous phosphoric acid solution, 
introducing the alkoxide and the phosphoric acid solutions into a reactor vessel wherein the solutions are immiscible and forming two separate liquid phases with an interface, 
applying agitation to at least the region of the interface to promote a reaction between the metal alkoxide and said phosphoric acid at the interface, 
collecting the reaction product, and 
firing it in an oxygen containing environment at a temperature sufficiently high to drive off the organic residue.

Abstract: A tube joint, especially for a flat tube evaporator (1), has at least one connecting tube (12) which is connected in a force-fit and fluid-proof manner to the inlet or outlet opening (9 or 10 respectively), by means of a connecting nipple (11). In this arrangement, the connecting nipple (11) has a first connecting nozzle (14), which is to be soldered into the opening (9 or 10 respectively) and a second connecting nozzle (17), holding the connecting tube (12). In order that the connecting tube (12) can be applied subsequently, cost-effectively and without adversely affecting and interfering with the operation of the flat tube evaporator, the second connecting nozzle (17) is designed as a seat (26) for the end (18) of the connecting tube (12) having a collar (19), and has a boundary shoulder (24) projecting beyond the collar (19) and bending into the seat (26) after insertion of the connecting tube (12). This boundary shoulder (24) ensures a fluid-proof and mechanically stable connection of the connecting tube (12) to the connecting nipple (11), and thus to the flat tube evaporator (1). <IMAGE>

Abstract: Process for preparing urea in which, 
- at a pressure of 125-350 bar and the corresponding temperature, a urea synthesis solution containing carbamate is formed from carbon dioxide and an excess of ammonia, 
- in a first decomposition step part of the carbamate is decomposed, with supply of heat and in countercurrent contact with a stripping gas, and the resulting gas phase is in part condensed in a first con-densation zone, 
- in at least two further decomposition steps a further part of the carbamate still present is decomposed and the gas mixture formed is separated off, in the first of the further decomposition steps a pressure of 4-40 bar being maintained, 
- the remaining urea-containing solution is processed by evaporation to form a concentrated urea solution, the heat required for evaporation being obtained at least in part by condensation of the gas mixture obtained in the first of the further decomposition steps. 
     The gas mixture used in the first evaporation step is formed by the gas phase resulting from the heat exchange between the part of the stripped urea synthesis solution expanded to a pressure of 4-40 bar and the condensing gas mixture in the first condensation zone.

Abstract: A DNA signal sequence initially isolated from  Streptomyces griseus  encodes a signal peptide which directs the secretion, via a fused intermediate, of a protein from the cell within which the DNA signal sequence is expressed. The signal sequence is derived from genes encoding protease A and protease B of  S. griseus . The DNA signal sequence encodes a thirty-eight amino acid signal peptide. A DNA construct, including the DNA signal sequence and a gene sequence encoding a protein, when transformed into a living cell by a suitable vector, results in the signal peptide correctly directing the secretion of a mature protein of desired structure, particularly from prokaryotic genera selected for their ability to display enzymatic activity of a type typified by, but not exlusive to, that of protein disulphide oxidoreductase, EC 5.3.4.1, more particularly in the genera  Streptomyces , and most particularly in  Streptomyces lividans  66.

IPC: B61L5/10
Filed: 1988-11-21
Abstract: The device comprises a geared motor (17) which drives longitudinally, via a ball screw (20) and nut, the central body (22) of a moving element comprising two slides (24, 25) sandwiching the central body (22). The two slides mesh on a common pinion mounted so as to rotate freely in the central body (22). Each slide drives, via a vertical, cylindrical floating pin (34, 35, 38, 39), a control bar (9, 10) linked to a throw rod (7, 8) which is itself linked to a switch blade. The locking of an operating bar (9, 10) is effected at the end of the travel of the central body (22) by the positioning of a floating pin in a locking groove (40 to 43) of a fixed locking plate (30, 31). A mechanical fault in the transmission chain causes a relative displacement of the slides (24, 25) with respect to the central body (22), which displacement is detected by the rotation of the common pinion integrally connected to means (27) for actuating an anomaly-control contact (29).

Abstract: In an hydraulic anti-skid braking system (Figure 1), a valve (2) controlling the flow of braking fluid to a brake actuator (1) is actuated by a pulse-driven stepper motor (14) in response to signals emanating from a skid sensor (16). In a practical arrangement (Figure 3), a motor (3, 6) under the control of a microprocessor (37) actuates a pressure dump valve (33) via an eccentric mechanism (34) upon the appearance of a skid signal at the sensor (38), in order to de-pressurise the actuator (30), and also drives a pump (36) which assists in re-pressurising the system when the skid signal ceases.

Abstract: The audience rating of broadcasts from a station (1), in particular a radio station or a radio/television station, is measured by recording in memory cards (4), principally electronic chip cards, metering units broadcast parallel with and at the time of broadcasts from the station. The parallel broadcast can be a broadcast coded within the radio-frequency band used. Preferably this parallel broadcast is made using a computerised telephone communications server (16) to which the memory cards of the listeners are linked by a reader/recorder (17) connected to a modulator demodulator (18, 19) interfaced (15) with this server. It is shown that measurement of the audience rating is improved, that the quality of the information extracted from this measurement is improved, and that the listeners are spared excessive costs. <IMAGE>

Abstract: In the conventional industrial robots, a maximum instructable speed is fixed irrespective of the kind of operation and the time constant during the acceleration or deceleration is fixed too, so that the load exerted on the motor that drives the robot arm will not exceed a maximum output. In the robot controller of the invention, a maximum speed and a time constant depending upon the content of operation of the robot are designated to the robot control axes (3) from a control unit (1) that includes a select table memory (4) for each kind of the operation that will be instructed to the robot. The robot therefore operates at high speeds without exerting increased burden on the operator.
