Abstract: ABSTRACT OF THE DISCLOSURE Electronic editing of a recording digital signal is carried out such that any errors created by the editing process are correctable.  The digital signal is given protection from errors, for example by a cross-interleaving technique, so that m-tupple errors in a code sequence length can be corrected when the signal is reproduced. The edit cut-in and cut-out points are controlled so that if multiple editing is carried out, fewer than m+l errors will be generated, and the edited signal will be free of clicks caused by uncorrectable error. The permitted points for cut-in and cut-out can be separated by a distance greater than the code sequence length.  Alternatively, if cross-interleaving is carried out such that digital words are grouped into blocks and provided with respective different delays that are integral multiples of D block lengths, the interval between such points can be selected to correspond to T block lengths, such that the least common multiple of D and T is greater than the code sequence length.                             -i-

Abstract: ABSTRACT OF THE DISCLOSURE         A  method of making a softener for rubber mixtures and furnace fuel oil comprises the steps of heating a hydrocar-bonaceous solvent and adding thereto waste from vulcanized and nonvulcanized rubbers under intensive stirring.  Then the waste is thermally decomposed at a pressure of 5-102 to 25-105 n/m2, the hydrocarbonaceous solvent continuously circulating through the reaction mixture.  The end product is separated from the formed suspension by distillation at a temperature of 200 to 560°C and at a pressure of 10 to 2-105 n/m2 in the presence of an inert gaseous agent.   The method of the present invention makes it possible to practically eliminate coking of the raw material in the course of the thermal de-composition and to upgrade the quality of the end product, as well as to improve its characteristics and the properties of rubber mixtures of vulcanizates.

Abstract: ABSTRACT OF THE DISCLOSURE        A method of pressing sheet material utilizing counterpad pressure to eliminate springback is disclosed. The sheet material is sequentially bent at paris of bend radii during first and second increments of striking.  The first increment of striking is carried out with little or no counterpad pressure to permit a curvilinear section to form immediately beneath the male punch member due to the bending moment.  The second increment of striking is carried out with a positive counterpad pressure effective to flatten the curvilinear section and thereby space the second pair of bend radii from the first pair.  Residual springback from the first bending action subtracts from the springback of the second bending to reduce the resultant springback in the product.

Abstract: Abstract Cheese curd is produced by coagulating a milk product during its passage through a long coagulator tube under renneting conditions giving a relatively slow coagulation course. The milk product is renneted in-line and the renneted mixture is fed periodically to the inlet end of the coagulator tube during feeding periods with inter-mediate stand still periods, the length of a feeding period being selected so that no essential coagulation occurs in the mixture from its introduction into the coagulator tube up to the successive stand still period, and the length of a stand still period being selected so that the mixture after having been subjected to one stand still period in the coagulator tube forms a sufficiently firm coagulum to be transported by feeding new mixture during the successive feeding period towards the outlet end of the coagulator tube as a continuous plug.          The speed of feeding mixture into the coagulator tube and the length of the coagulator tube are adjusted so that the residence time in the coagulator tube comprises at least one feeding period and one stand still period.

Abstract: OFF-HIGHWAY VEHICLE RIDE STRUT AND METHOD                ABSTRACT A compressible liquid ride strut includes a pored piston which reciprocates in a cylinder chamber to divide the chamber into two sections.  The piston ports provide controlled flow of liquid from one section to the other. A valve member engages the piston upon extreme rebound strut extension to greatly diminish flow of liquid through the piston and increase the re-bound dampening rate of the strut. The valve member is acted on by a pair of springs which hold the valve member away from the piston during normal operation and permit it to move against the piston during rebound.

Abstract: ABSTRACT An oil well casing assembly includes a perforated tube and upper and lower packers coupled to the upper and lower ends of the tube.  The lower packer is in turn coupled to a spacer tube and the upper packer is connected to a casing string.  Each packer includes an elastomeric sleeve bounded by upper and lower collars.  The packers are so arranged that when the casing assembly is lowered into the borehole and comes to rest at the bottom of the borehole, the weight of the casing assembly is used to cause the elastomeric sleeves to swell out against the borehole surface, thereby sealing the casing assembly above and below the payzone.  In addition, a casing seal is provided which comprises an elasto-meric sleeve positioned between upper and lower rings around a pump column included in the casing assembly.  The upper and lower rings are so mounted that the weight of the pump column causes the elastomeric sleeve to shorten axially and to swell out against the inside of the casing string, there-by providing an effective, airtight seal between the pump column and the casing string.  The packers and casing seal of this invention can be used in a method for sealing a cas-ing in place such that the casing can be removed when neces-sary.  Furthermore, the normal pumping action of the pump inside the pump column serves to remove oil from the payzone area and, because of the seals provided by the casing seal, to reduce pressure in the payzone, thereby promoting the flow of oil into the perforated tube.  This method can be used with other types of seals between the casing and the borehole and between the pump column and the casing.

Abstract: INPROVED FREE-STANDING COLLAPSIBLE FRAME      STRUCTURE AND HUB ASSEMBLY THEREFOR                         ABSTRACT OF THE DISCLOSURE  This invention relates to an improved free-standing tent frame having at least three four-sided collapsible subframes linked together in side-by-side relation and angled relative to one another so as to stand alone while leaving a gap between the endmost subframes, and a triangularly-segmented roof frame having one more triangular segment than there are subframes in the wail structure, the triangular segment above the gap having internal bracing in the form of a central hub and struts radiating to the corners that cooperate with one another and the wall subframes on either side thereof to define a rigid arch, and like internally-braced triangular segments constituting at least every other segment on both sides of the one bridging the gap.  The invention is also characterized by a hub assembly for the subframes of the wall assembly that comprises a series of three or more strut-receiving socket subassemblies hingedly interconnected to produce a closed polygon in which those having four or more sides are self-adjusting to accommodate various included angles between adjacent struts without the latter having to bow or bend. The three-sided hub subassembly, while rigid, can, through the addition of a spacer plate, be arranged so that the included angle between adjacent struts is other than 120°.  The invention further encompasses the socket subassemblies which employ the hinge pins at opposite ends of the hinge member as keepers to retain the pivot pin of the socket-receiving element in place while the wedge-actuated fingers of the latter releasably grip the hollow strut end without the need for adhesives or more conventional fasteners.
