Abstract: LOCAL ANNEALING TREATMENT   FOR CUBE-ON-EDGE GRAIN ORIENTED SILICON STEEL ABSTRACT OF THE DISCLOSURE A process for improving the core loss of cube-on-edge grain oriented silicon steel.  At some point in its rout-ing after at least one stage of cold rolling and before the final high temperature anneal during which secondary grain growth occurs, the electrical steel is subjected to local annealing across its rolling direction creating bands of enlarged primary grains.  These bands of en-larged primary grains regulate the growth of the secon-dary cube-on-edge grains in the intermediate unannealed areas of the electrical steel strip during the final high temperature anneal, and are themselves ultimately con-sumed by the secondary grains, providing a cube-on-edge grain oriented electrical steel with smaller secondary grains and reduced core loss.

Abstract: 19.                          Abstract A process for the production of cement-concrete by intimate mixing of aggregates, cement, optional filler, and water in a concrete mixer, wherein the fine fraction of the aggregates is only added into the mixer after the remaining components have been mixed, with the result that the coarse fraction of the aggregates is coated with a paste, consisting of cement, optional filler, and water in which the fine fraction is absorbed. The addition of the fine fraction is effected successively, controlled by the proportioning means for the fine fraction, preferably by controlled vibration technique. The fine fraction is advantageously added into a zone of the mixer in which the mass consisting of the paste-coated coarse fraction and free-flowing cement paste is moved in a material flow under the influence of an external pressure from the mixing means. In the plant for the realization of the process and comprising a mixing container with proportioning means for the components of the concrete, mixing and discharge means, the proportioning means for the fine fraction of the aggregates is equipped with devices for the control and regulation of the flow of the fine fraction, and is preferably a vibratory feeder.      A homogeneous concrete having excellent strength properties is obtainedwith considerable cement savings.

Abstract: SPECIFICATION            TITLE OF THE INVENTION:  Process for Drying Foods under Reduced Pressure ABSTRACT OF THE DISCLOSURE:     A process for drying a food under a reduced pressure is provided  for  the preparation of a dried food which may be rehydrated to the original condition in a very short time to have pleasant taste and texture substantially comparable to an untreated food.   The process is characterized by the step of placing  the food to be dried  in an environment of reduced pressure  low  enough  to vaporize  a  portion  of  the  water contained in the food and to freeze the balance of water by the rediation of heat by the vaporization, and the step of heating to dry the food at relatively low temperature under the reduced pressure.  A further characteristic feature of the process of the invention is the sudden or abrupt drop of the pressure surrounding the food at the initial stage, whereby the food is puffed somewhat by the action of the vigorously vaporizing water to a dried state with a substantially hollow core portion and a denser surface layer.

Abstract: ABSTRACT            FLOORING The invention relates to flooring e.g. for pig units using a number of plastics flooring panels  supported  above  an effluent collecting space.    Known panels have necessary surface formations for anti-slip purposes which effectively hinder cleaning, and are interconnected by edge formations making removal of an individual panel difficult, and supporting a panel cut to a size for an area requiring less than a full panel equally difficult.  The invention avoids these difficulties by first providing a panel that is provided with surface formations on an otherwise plain surface,` to impart anti-slip characteristics,  and with drainage holes,  said formations being ribs formed horizontally and transversely of the panel and interconnected to form a number of rectangular enclosures for a number of drainage holes, and secondly providing a support structure having two parallel bar-like members, there being a number of such  support  structures  provided  in  spaced relationship over an area where the flooring is required, and a number of panels, each panel having at at least two opposite edges, a recess emerging at its under-surface and spaced from the respective edge, said recess being adapted to accept one of the bar-like members of the support structure and whereby two adjacent panels can be located in side-by-side relationship on one support structure.

Abstract: ABSTRACT A knitting machine element has an elongated shank arranged for longitudinally displaceable support in a corresponding slot of a needle bed or the like.  The shank is defined laterally by smooth flanks and is laterally bent or bendable at at least one predetermined location, the bend being at the bottom of a recess or depression extending transversely to the longitudinal axis of the shank in the associated flank or side wall of the shank.  To ensure that the needle shank will rest in a biassed manner with a soft spring characteristic and with uniform frictional force on the side walls of the associated needle slot, and to avoid shank breakage or excessive soiling or wear of the needle slot, the arrangement is such that the recess or depression is filled with a vibration damping material, e.g. a plastic, which is bonded to the shank.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention provides an apparatus for supervising a digital radio transmission path between a transmitter and a receiver, in which the transmitter transmits a message including a data signal and a predetermined bit pattern portion, the portion being used for error rate detection; the receiver receives the portion, produces error pulses from the portion by comparing the portion to a reference and supervises the transmission path quality based on the produced error pulses to issue a path switching command when the detected error rate exceeds a predetermined threshold value.  The apparatus comprises a device for producing a first number equal to the number of received error pulses by counting the received errors in the portion and for producing a second number proportional to a time interval between two successive error pulses; and a comparison unit which receives the first number obtained by counting the received error pulses and the second number produced in accordance with the time interval between two successive error pulses, and produces the line switching command when the first number is greater than or equal to the second number.  The supervisory system rapidly detects deterioration in the quality of the digital radio transmission line and performs the line switching when such deterioration is detected.

Abstract: ABSTRACT:           A cathode ray tube comprising a channel plate electron multiplier structure disposed between a source of electrons and a cathodoluminescent screen, the electron multiplier comprising a stack of n apertured dynodes.  The dynodes are separated from each other and are arranged in cascade with the apertures in adjacent dynodes aligned to form channels.  When designing dynodes an aspect ratio is generally adopted that the axial length of the aperture, which length corresponds to the thickness of the dynode, is the same as the input and output cross-sections of the apertures, which are of re-entrant form.  If this aspect ratio is maintained for high resolution dynodes then the dynodes would be so thin as to make them difficult to handle.  This problem is mitigated by changing the axial profile of the aperture in at least the second to the (n-1)th dynodes such that it comprises a re-entrant por-tion (24) within the thickness of the dynode (10) with the axially spaced ends (26,28) of the re-entrant portion (24) being spaced from the respective opposite surfaces of the dynode (10) by a convergent or cylindrical input portion (20) and a divergent or cylindrical output portion (22). The axial length of the re-entrant portion (24) corres-ponds substantially to the cross-section of the input (or output) portion at a point where it communicates with the re-entrant portion (24).
