Patent GB-2005042-A (GB)
Title: Improved imaging methods and elements based on organo tellurium compounds
IPC: G03C1/735
Filed: 1978-09-21
Abstract: Heat developable light sensitive materials based on organo tellurium compounds which are more sensitive to actinic radiation and produce denser images are obtained if the organo-tellurium compounds are dispersed (rather than dissolved) in a cellulose triacetate binder. The dispersion is prepared by dispersing the cellulose triacetate binder in a solvent eg ethylene dichloride and adding thereto a solution of the organo-tellurium compound in the same solvent. This dispersion is subsequently coated on a support to form the light-sensitive material. The stability and sensitivity of the materials are further improved by the addition of pyrazine, pyridazine, quinoxaline or their alkyl or halo derivatives and a mixture of duroquinone and hydro duroquinone, trimethyl-o-acetate or acetone.

Title: Determination of a characteristic of metal sheet or strip
IPC: G01N23/20
Filed: 1979-03-13
Abstract: The anisotropic value rm of cold rolled, recrystallization annealed thin and very thin metal sheet 2 is determined by employing X-rays 1 for the measurement of the crystallographic texture. The sheets are irradiated with incident primary radiation at an energy of at least 20 keV, the rays diffracted at the crystal lattices are detected 3, and the detected X-ray quanta are converted into voltage pulses proportional to their energy. The voltage pulses are then discriminated in respect of pulse height and the maxima and the frequency distribution of the pulse heights are arranged in accordance with predetermined diffraction reflexes, so that the intensity of the diffraction reflex is measured at fixed values of the latitude angle  alpha  and the azimuth angle  beta . <IMAGE>

Title: Rotary compressor
IPC: F04C29/02
Filed: 1979-06-13
Abstract: A compressor of the sliding- vane eccentric-rotor type has a lubrication system (33) leading from a sump in the compressor casing (16) and operated by differential pressure between the sump and the parts to be lubricated. A disposable full-flow filter element (25), typically of 5 to 20 micron rating, is positioned in the lubrication system (33) to remove at least the majority of smaller gas-ingested particles thereby protecting an oil separator element (172) from becoming clogged with these particles. By protecting the oil separator element (172) in this manner it is practicable to use a sub-micronic filter for the oil separator (172) so that droplets of oil can be separated from the compressed gas with greater efficiency. The lubrication system (33) may also incorporate an oil cooler (27) and a by-pass valve (204) which ensures effective lubrication if the filter element (25) becomes blocked. <IMAGE>

Title: Controlling gas-shielded consumable electrode arc welding in dip transfer mode
IPC: B23K9/09
Filed: 1979-07-20
Abstract: Arc welding using a gas shielded consumable electrode in the dip transfer mode is controlled by sensing the dip transfer frequency by sensing frequency of current peaks, voltage dips (as shown) or, optically, arc light and adjusting either the speed at which the electrode is fed towards the molten weld pool or the level of arc current and/or voltage to obtain substantially maximum dip transfer frequency and, hence, optimum welding conditions. The sensed dip transfer frequency may be used to provide audible and/or visual signals for parameter control by an operator, or, as shown, used in an automatic retroactive control. <IMAGE>

Title: Improvements in and relating to switches and to timing apparatus controllable by such switches
IPC: G05B19/10
Filed: 1980-02-05
Abstract: A timing circuit arrangement suitable for timing cooking operations in which "time of day", "cook time" and "ready time", for example, are required, includes a time-division- multiplexed electrical system comprising IC11 Fig. 3 which provides data input, data output and address output highways. Switches are connected between the highways for controlling the system, and a digital time display (not shown) is connected between the data output and address output highways 12, 13 for displaying selected contents of an alterable data store or register within IC11. The set time switches S1, S2 Figs. 1, 2, 5 may be operated by means of a rotatable member. Pulse sequences, Fig. 1A, from S1, S2 are fed via D2, D4 to inputs K2, K4 of IC11. The latter samples the states of K2, K4 periodically and establishes conditions within the alterable store according to the logic states of K2, K4 during two consecutive samplings and whether the states have changed. Clockwise rotation of the member results in accompanying changes in the contents of the alterable data store, the changes being shown as sequential incrementing of the display, and anti-clockwise rotation result in decrementing. Rotation results initially in changes to the units of the display, but when a 9 to 0 change occurs, changes to the tens follow thereafter until adjustment ceases. A rotary control switch suitable for controlling the timing circuit employs components e.g. Reed contacts Figs. 1, 2 or Hall effect devices sensitive to a magnetic field to act as the input switches, and changes of the magnetic field takes place as a rotatable member is moved. <IMAGE>

Patent GB-2077610-A (GB)
Title: Pocket centrifuge and method of operating same
IPC: B04B9/10
Filed: 1980-06-12
Abstract: A pocket centrifuge has a plurality of sieve pockets 4 having sieve surfaces and orbitable about an axis with the sieve surfaces forming sieve angles  alpha  with perpendiculars to planes including this axis. A filtrant is fed radially to these pockets so that solids collect on the surfaces thereof and a filtrate passes through the surfaces. These solids have a friction angle measured to a perpendicular to the centrifugal force acting on them which is dependent on the magnitude of this force and their coefficient of friction. The angular orbiting speed of the pocket is periodically varied between one speed at which the respective friction angle of the solids is smaller than the sieve angle and the solids slide on the sieve surface and another angle at which the respective friction angle of the solids is greater than the sieve angle and the solids sit on the sieve surface. This variation in angular orbiting speed can be obtained by periodically braking or accelerating the rotor carrying the pocket, or by mounting this rotor for rotation about two axes for continuous acceleration and deceleration of the pockets. Alternately the sieve angles can be changed by pivoting the pockets on the rotor to achieve the same effect. <IMAGE>
