Abstract: METHOD & GUAGE FOR NONDESTRUCTIVELY TESTING AND   CERTIFYING THE WORKABLE QUALITIES OF A CASTING            ABSTRACT OF THE DISCLOSURE:           The invention is directed to a method and guage for nondestrictively testing and certifying the workable qualities of a casting.  The guage comprises a tab cast at the same time as the remaining portion of the casting located in a nonfunctional location, when considered in the light of the later use to be made of the casting, and also in such a position that it can be bent as by striking with a percussive instrument or by the application of a continuous bending force without damage to the remaining portion of the casting.  The tab or guage will be subjected to a strain greater than the maximum strain to which the remaining por-tion of the casting will be subjected, during its installa-tion or use, and determining by visual inspection whether or not the tab, at its bend has cracked, the overall ductility of the casting can be judged and it can be projected, that the casting will be able to withstand the forces to which it will be subjected when employed in a desired manner.  The tab will take on a generally rectangular configuration of prescribed minimum height, width, and thickness, such that it may be correctly subjected to strain forces in excess of the strain forces to be applied to the casting during its normal use or installation.

Abstract: Suction Stabilizer for Reciprocating Pumps  and Stabilizing Method ABSTRACT OF THE DISCLOSURE           A suction stabilizer for reciprocating pumps and method of stabilizing the inflow of liquid to the suction side of the pump,  The stabilizer comprises a substantailly cyl-indrical tank, a perforate-walled cage at one end of the tank, and a flexible resilient gas-filled bladder within the cage.          Liquid passes through the tank as it moves from a source to the suction side of the pump.  Between suction strokes the liquid compresses gas in the bladder.  During suction strokes the pressure of the gas adds to the head of liquid entering the pump.  The invention involves critical ratios of the tank volume to both the pump displacement and the bladder volume.

Abstract: ABSTRACT        A digital linear phase shift convolutional filter for filtering a series of binary number electrical signals each of which represents the magnitude of a sample of an analog electrical signal sampled at a predetermined rate. The convolutional filter utilizes a bidirectional shift register and a preferably unidirectional shift register. Each of the registers has a plurality of stages.  The bi-directional shift register receives the serially presented binary number electrical signals representative of the sample magnitudes, and these samples are sequentially transferred from the output stage of the bidirectional shift register to the input stage of the unidirectional shift register.  During the interval between receipt in the bidirectional shift register of binary number electrical signals representative of the sample amplitudes, the binary number electrical signals stored in the bidirectional shift register are shifted in a recirculating fashion, as are the binary number electrical signals stored in the unidirectional shift register.  The binary number electrical signals appearing in particular stages of each of the registers are combined arithmetically to produce a resultant binary number electrical signal with each shift in the recirculating shift registers.  These resultant signals are multiplied by constant values representing filter weights, and the products are summed to produce an output binary number electrical signal.  One such output signal is produced for each new sample that enters the bidirectional shift register.

Abstract: ABSTRACT    A machine for the injection of liquid into the surface of soil comprises a sledge having a surface compacting base bounded by two runners, the lower surface of each runner being below the level of the compacting base.  The base has a transverse slot dimensioned to receive a hollow pressurisable injection bar which has a lower face equipped with injection orifices, the lower face being flush with the compacting surface of the compacting base when the bar is in position.  The machine is particularly useful for the injection of soil stabilising medium into soil whilst the soil is compacted. By this means it is possible to produce a compacted raised strip of soil which is smooth and stable and which in desert conditions prevents a build up of sand on roads.    The invention includes a method fro stablising soil by forming a compacted raised strip of soil and injecting a soil stablilising medium into said strip to bond the compacted soil.
