Abstract: A gypsum-based pesticide product and method of manufac­ture of such product in which the product has a release time for the pesticide which is determined at least in part by its size and in which the gypsum is a solid formed by the bonding of plaster of Paris and water. The product, prior to formation of the solid, includes, by weight, no more than about 20% water, approximately 5% of pesticide, with the balance plaster of Paris. The ingred­ients, prior to formation into a solid, are intimately mixed for a time period which is only a fraction of the setting time of the mixture with the amount of water being no greater than that re­quired to completely set the plaster of Paris into gypsum.

Abstract: Colored resinous particles suitable for use in toner powder for developing electrostatic latent images are produced from a pulverized feed at a good produc­tion efficiency and with a sharp particle size distribution through a classifying and pulverizing system including a second pulverization step associated with a second classification step in addition to a first classification step, such a second classification step and a first pulverization step. The pulverized feed supplied to the first classification step is classified into a first classified fine powder and a first coarse powder, which is then pulverized in the first pulverization step and recycled to the first classification step. The first classified fine powder is supplied to the second classification step and classified therein into a second classified fine powder and a second coarse powder, which is then pulverized in the second pulverization step and recycled to the first classification step or the second classification step. The second pulverization step is effected under the action of an impact force which is smaller than that exerted in the first pulverization step.

Abstract: Holding device for slab-like cladding elements (1) which are intended for the finishing and facade formation of buildings. The mounting of these holding devices is very expensive, since considerable preliminary work, in particular the fastening thereof to the surfaces (5) to be clad and to the cladding elements (1), has to be carried out for this. The object of the invention is therefore to provide a holding device (3,6) which simplifies the mounting of cladding elements (1). The holding device according to the invention possesses holding elements in the form of pins (3) or tongue-like tabs (6) which are fastened to the surfaces (5) to be clad and are engaged in cut-outs (2,4) on the rear side of the cladding elements (1). <IMAGE>

Abstract: The pressure in a continuous high pressure polymerization system, in which ethylene, with or without comonomers, is polymerized under high pressures and temperatures and the unconverted amounts of gas are recycled through the high pressure recycle gas system into the polymerization system, is rapidly reduced to below the particular reaction pressure when predetermined limiting pressure and/or temperature values are exceeded or when other faults occur by opening one or more pressure-relief apparatuses mounted on the high pressure polymerization system and transferring the hot let-down reaction mixture from the polymerization system via one or more let-down lines through one or more separator systems into the atmosphere, by a process in which the high pressure polymerization system is divided into a plurality of isolated sections at the same time as the let-down process is triggered and only the section in which the let-down process is triggered is let down to the atmosphere. Preferably, the sections in which the let-down process is not triggered can be let down into the high pressure recycle gas system, if necessary through a product separator, in synchronization with triggering of the let-down to the atmosphere.

Abstract: A display controller employs timing signals to control a display on a screen of a display device in respect of each of a plurality of pixel unit regions (R) as is known. However, the overall area of the display is effectively sub-divided into fixed data areas in which the data to be displayed are fixed and variable data areas in which the data to be displayed can be varied. A first ROM (3) provides, in relation to each of the unit regions (R), an area flag signal (F) indicative of whether the unit region is in the fixed data area or in the variable data area. This first ROM (3) stores fixed data representing the data to be displayed when the unit region is in the fixed data area as well as address data to access a RAM (4), which stores variable data representing the data to be displayed in the variable data area. A second ROM (6) receives the fixed data or the variable data, depending on the flag signal, and generates display pattern data held by a latching circuit (7) which drives the display device.

Abstract: A method of lining an irrigation canal (10) with a sheet of fiber-­reinforced plastic includes the steps of depositing a layer of resin and fiber on a web of flexible carrier material, partially curing the resin prior to laying the sheet in the canal, and then laying the sheet in the canal while the resin is flexible enough to conform to the shape of the canal. The final curing of the resin takes place after the sheet is placed in the canal. A predetermined-shape wrinkle (38) is induced in the carrier web before it is laid into the canal to assist in conforming the sheet to the canal shape without causing randomly placed wrinkles so that the sheet is smooth in the canal. An apparatus (18) is disclosed that forms the sheet and is propelled so that it travels along the length of the canal, fabricating a continuous sheet as it travels. In one embodiment the carrier is a flexible but nonelastic material like kraft paper, coated on one side with wax or other film to prevent saturation by the resin.

Abstract: A device and method for the rapid quantification of the amount of urine in a human bladder. Ultrasonic transducer (1) is positioned in proximity to the bladder (12-13), and excited by pulser/receiver (3) under command of logic (4) to launch an acoustic wave into patient (2). This wave interacts with the bladder walls (12, 13) and is reflected back to the transducer (1), whence it is amplified and processed by pulser/receiver (3). The resulting signal is digitized by analog-to-digital converter (5) under command of logic (4), and stored in memory (6). The software in logic system (4) determines the amount of urine in the bladder as a func­tion of the propagated ultrasonic energy and based on programmed scientific measurements and past history with the specific subject, and actuates an alarm.

Abstract: A crossed-field amplifier circuit has a CFA tube (30) with respective slow-wave structures (31,32) for the anode and the cathode, each with an input (33,35) and an output terminal (34,36) and a magnetic field (28) in the axial direction. Signals of the same frequency from a common source (40) and of controlled phase difference and amplitude (39,41) are applied to the input terminals (33,35) of the anode and cathode slow-wave structures (31,32) whose fringing fields interact with the electron cloud between the anode and the cathode to form well defined cloud fingers (43). The resultant amplification of the input signals provides at the output terminal (34) of the anode an amplified signal having lower random noise than hitherto available from CFA amplifiers.

Abstract: Blocks of digital information for computer programs and/or data are broadcast (30) by way of teletext pages and can be used by computers (43) connected to suitable receivers (40) (telesoftware). The data of one or more pages of the teletext system define in coded form a configuration chapter containing the items of information for access to other teletext pages, the digital information in respect of which constitute a given file of programs and/or data for the receiving computer. The transmission/reception protocol is organised in eight levels of which the lowest two levels are common to the teletext system and concern the apparatus for transmission/reception of the radio signals, and coding/decoding (41) of digital signals extracted from the radio signals and the temporary storage thereof. Other levels of the system are respectively intended to extract from the stored data correct data which are devoid of errors and which are appropriate to the operating environment of the transmission and/or reception apparatus, and to define more chapters forming the file. Finally in the eighth level the transmitted transmissions may be optionally ciphered (35) in accordance with suitable keys to permit reception only by persons who have deciphering apparatus enabled by corresponding deciphering keys.
