Abstract: In a digital video signal processing apparatus having error correcting and concealing capabilities, a video signal is converted to a digital signal and transmitted or recorded with error detecting and error correcting signals. Upon receiving or reproducing the transmitted signal, an error in th digitized video signal is detected by means of the error detecting signal, and corrected, if possible, by means of the error correcting signal. If the error is so extensive that its correction by the error correction signal is not possible, the erroneous signal is concealed by its replacement with a substantially corresponding signal of the previous field which has been stored in a suitable memory.

Abstract: A bioassay method is based on the detection of changes in the membrane potential of individual cells. A cell suspension is incubated with a solution of a substance capable of affecting the physiology of at least a subpopulation of cells in the suspension. During or after the incubation, a measurement representative of the membrane potential of individual cells is made. The preferred method of measuring membrane potential involves incubating the cells with a membrane-permeant, fluorescent, ionic dye which becomes distributed on opposite sides of the cell membrane as a function of membrane potential, and then assaying intracellular dye concentration by photometric measurements in a flow cytometer. 
<??>In one embodiment the cells are modified prior to the photometric measurements; this modification may involve reaction with, for example, hormones, pharmacological agents and proteins. 
<??>One application of the invention is in the evaluation of drugs.

Abstract: A transmitter element, for use in connection with a lifting device to generate an electric signal corresponding to the load being handled comprises a tensile link (1) to which strain gauges are attached. At least one safety link (3) is disposed in parallel with the tensile link (preferably two safety links, one on each side of the tensile link) and is designed to absorb greater loads than the tensile link. In normal operation the tensile link will absorb the entire load acting on the transmitter element. However, the safety link will take over at least a portion of the load acting on the tensile link if the latter is ruptured or abnormally elongated. The transmitter element can be used in a lifting device with a stationary pulley wheel to support one end of the pulley axle, whereas the opposite end is pivotally supported in the frame of the lifting device. <IMAGE>

Abstract: The ignition circuit includes a cold start unit (A) having an oscillator which develops a direct voltage at its output (1) higher than the prevailing voltage of the battery (G). The oscillator supplies the increased voltage only during operation of the starter (F) when a positive potential is applied to a control input (3) via a connection to the starter solenoid (E,H). The oscillator has a transformer coupled output which also provides a d.c. path between its supply input (2) and the output (1) for normal unboosted current supply to the ignition coil (B) after the engine has been started. Conversion of a conventional ignition circuit is achieved simply by inserting the unit (A) between the ignition switch (D) and the coil (B) and making the control input connection to the starter solenoid (E,H). <IMAGE>

Abstract: The plant according to the invention for the heat treatment of pellets consists of a transport mechanism 1 for the introduction of the pellets. It also comprises the following parts, viewed in the material flow direction through the system and in the direction in which the transport mechanism 1 moves: drying chambers 2,3, a firing or combustion chamber 4 with an arrangement for the introduction of a gaseous fuel, a cooling chamber 5, and a system for the forced introduction of air into the chambers and for the removal of the combustion products from the pellet layer on the transport mechanism 1. The fuel inlet device of the combustion chamber 4 consists of a distribution grill 11 which is arranged in the lower part of the combustion chamber 4 and is separated from the transport mechanism 1 by a distance representing from about 1/10 to about 1/4 of the height of the combustion chamber 4. The distribution grill 11 is so mounted that it occupies at least 40% of the horizontal surface of the combustion chamber 4. This distribution grill is formed by pipes 12 with an orifice for the supply of the gaseous fuel and by water-cooled pipes 13 that lie below the pipes 12 in the parallel direction. These pipes ensure the radial flow of the mixture of gaseous fuel and air in the pellet layer when the combustion products are being expelled from the pellet layer lying on the transport mechanism 1. <IMAGE>

Title: Antiskid devices for tyres - mounted so that only when tyre skids are devices moved proud of the tread to bite into road surface
Inventor: LINDMARK PETER
IPC: B60C11/16
Filed: 1981-12-16
Abstract: Anti-skid devices are mounted in a tyre so as normally not to protrude from the tyre tread. The mounting is such, however, that when the tyre skids the tips of the devices engage the road and the devices are pivoted relative to the tread so that the devices move proud of the tread and dig into the road. In some embodiments, pins are carried by flexible rods which run in the tread grooves and the flexure of which allows the devices to pivot proud of the tread. In other embodiments pins are mounted upon ridges formed in the tread grooves, which ridges flex to allow the device to move proud of the tread. The devices have minimal contact with the road during normal driving and thus there is reduced noise and road wear.

Abstract: A circuit for driving an electrical load such as an electric motor, by a pulse width modulated current includes a saturable current driver connected to the load. The circuit includes a linear transconductance amplifier with current-sensing feedback for applying a pulse-width modulated control current to the driver. The feedback preserves the extent of saturation and of cut-off by providing current pulses which are invariant with respect to thermally induced changes in circuit parameters. Amplitude and offset control circuitry are also provided for setting the range of current values during the current pulsing to optimize the operation of the driver. In an alternative simplified circuit, a low-level switching circuit drives complementary output transistors operating in a linear fashion, and producing current pulses which are invariant with respect to the saturable driver parameters.

Abstract: In the method, spent digestion liquid, which originates from digestions of cellulosic vegetable material by means of organic solvents at elevated temperature and elevated pressure, is subjected to flash evaporation. In order to avoid precipitation of the lignin degradation products during the cooling involved in flashing in the form of viscous and tarry products, which are difficult to transport, and, furthermore, occlude substantial quantities of solvent, and to improve the degree of recovery of the digesting agent, the vaporisable constituents of the digestion liquid are completely removed by a single-stage flash evaporation with heat supply and separated by distillation, and the non-vaporisable residue is recovered in a solid form. <IMAGE>

Abstract: The components (3), evenly distributed over the periphery of the spindle (1), each with at least one edge line, extend at least over the spindle width. The components can be lowered against the spindle for axial withdrawal of a completed roll. Each of them has a rectangular cross-section with the cross-section short sides facing one another. When they are in the work position the surfaces corresponding to the rectangular cross-section long sides cover preferably approximately 55 per cent of the peripheral surface. The components extend parallel to the axis of the spindle or in screw line fashion relatively to the spindle axis. The outwardly directed surfaces corresponding to the cross-section long sides are axially weakly concavely formed. The roll as the result of locally axially outwardly directed forces extending over the roll width has barely visible shape alterations of the layer of strip-form material. The shape alterations are strongest in the innermost layer and successively decrease with increasing roll diameter.
