Abstract: A key lock has provision for electromechanical release from a central station in the event of fire or other emergency. The dead bolt 9 is normally key-operated through a runner pin 14 working in a drive slot in the bolt tail. For remote release in an emergency a lever 22 is provided, loaded by a strong spring 24. This lever is normally held inoperative by a second, detent lever 25. The latter can be released by pulsing a solenoid 29, this in turn releasing the lever 22 to drive back the runner pin 14 and bolt 9 under the influence of its spring 24. Only a short pulse of electrical energy is required in order to trigger release of the lever 22 and the force for emergency withdrawal of the bolt comes from the spring 24 rather than electrically, so power-consumption is very low. The lever 22 can be reset after any such operation by a key-engageable member 38, the next time the bolt is thrown out again by the key.

Abstract: Velocity errors in a video signal are sampled at scan line rate and are averaged over a selected plurality of frames to enhance the repetitive velocity errors while cancelling the random velocity errors. The resulting separated repetitive velocity errors then are subtracted from the initial combined velocity errors to provide separated random velocity errors. A repetitive error interlace technique is used to generate an improved repetitive error frequency control signal, while a second order correction technique provides a corresponding random error frequency control signal. The two frequency control signals are combined and the combined signal is used to provide compensation for the initial velocity errors.

Abstract: There is provided a fire stop device (10) having a closure for a conduit (20) passing through an aperture extending through a wall, floor or the like. Fire resistant movable closure (22) means are operatively associated with the aperture. The closure means are movable between a first retracted position and a second functional position wherein the aperture is closed-off by the closure means. Self-sustaining restraining means of a heat disposable low-temperature melting metallic substance are used, the material being dispersible into a non-sustaining form when heated above the melting temperature thereof. The restraining means retains the closure means in the first position while permitting it to move to the second position when the substance is dispersed upon being heated. Means (26) are also provided for normally urging the closure means in the second position. Thus normally combustible thermoplastic conduits can be used up to the fire stop without affecting its operation.

Abstract: In this process, an alkaloid-containing lupin extract and a protein- and fat-containing substance from which the alkaloids have been removed are obtained from the previously ground seed kernels by a stepwise separation process which has an extraction phase, is carried out at 5 to 15 DEG C with partial exclusion of air and using SO2, and which operates by the counterflow principle with aqueous, previously enriched extract solutions of decreasing concentration. After extraction, the lupin extract is fermented at a temperature of below 35 DEG C to 40 DEG C, under the action of air, during which process its pH rises by 0.2 to 0.5. The yield-increasing and growth-enhancing effect of the lupin extract on plants is substantially increased and the protein losses are substantially reduced.

Abstract: The invention relates to magnetic resonance imaging methods and apparatus wherein each view of the magnetic resonance image is phase encoded with one of a plurality of phase encode gradients which vary from each other by a multiple of a phase encode gradient interval or step so that for a given field of view, the resolution is determined by the upper and lower limit phase encode gradient angles, the larger the limit angle, the finer the resolution. In such a system, when the imaged subject is shorter in dimension along the phase encode axis than the dimension of the field of view of the image along the phase encode axis, a portion of dead space other than the subject is imaged. In accordance with the invention to shorten the imaging time, the number of views is reduced in accordance with the ratio of the subject dimension to the field of view. The size of the phase encode gradient steps of intervals is increased by the same ratio such that a reduced number of views spans the same upper and lower phase encode gradient angle limits. This stretches the resultant image. When a generated image representation in an image memory is displayed, an inverse zoom reduces the dimension of the resultant display by the inverse of the ratio such that the a man readable display is returned to the proper scale. Along a frequency encode axis which is transverse to the phase encode axis, a bandwidth of frequencies corresponding to extremes of a projection of the subject are determined. Received resonance signals are filtered to remove frequency components which are outside of the determined bandwidth.
