Abstract: ABSTRACT              Digital filter for filtering non-uniformly quan-tised pulse code modulatad signals formed by a sequence of code groups x(i), each comprising a polarity bit, a segment number and a mantissa number.  This digital filter arrange-ment comprises a generator which cyclically generates a series of sequentially occurring auxiliary numbers each comprising a polarity bit and an address code; a first storage medium for storing the code groups x(i) and con-trolled by an address computation circuit to which the aux-iliary numbers are applied; a second addressable storage medium to which a segment number s(i-h) a mantissa number m(i-1), supplied by the first storage medium, as well as a polarity bit supplied by an exclusive OR-gate are applied as the address code.  This polarity bit is derived by gate from the polarity bit p(i-1) of the code groups x(i) and the auxiliary numbers polarity bit.  This second storage medium contains positive numbers zp and negative numbers zn which represent the expanded values of all possible code groups x(i).  A positive number zp is read from the storage medium if the polarity bit is positive and a neg-ative number is the polarity bit is negative.  The numbers read from the storage medium are applied to an accumulator which is coupled to an address code output of the gener-ator.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for protecting the transducer in liquid-filled differential pressure transmitter having stroke limited, isolation diaphragms from exposure to overrange pressure are disclosed.  Bidirectional overrange pressure protection is provided through the use of a single, preloaded bellows that is restrained by a preloaded stop means preferably including a preloaded mechanical spring.  The bellows remains stationary when the differential pressure transmitter is exposed to a normal, operational differential pressure.  When an overrange pressure is applied to the transmitter, the bellows expands or contracts to accommodate the liquid displaced by either of the isolation diaphragms thereby protecting the transducer from the overrange pressure.  Upon removal of the overrange pressure condition, the protection apparatus automatically resets itself.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to the units of a pouring system for uphill teeming.  Conventionally, such units are formed by a pouring trumpet having a two-part heavy duty iron casing, and by runners set in channels in a heavy cast iron base plate, requiring skillful assembly on site.. When unskilled personel are utilised there is frequently incorrect assembly and positioning, leading to jointing and cracking, faults which in turn leads to molten metal penetration during pouring with consequent damage to the cast iron casing of the trumpet and the case iron base plate with the inherent danger of a complete break-out.  The objective of the invention is to alleviate the problems outlined above, that objective being met by providing the units of a pouring system for uphill teeming each comprising an outer casing, an inner refractory liner and a refractory insulating material between the outer casing and the inner liner, each unit being pre-assembled as a complete unit for delivery to a casting bay. Considerable further advantages are realised when the outer casing is of a destructible material such as a cardboard tube.

Abstract: 915,703 ABSTRACT           A method and article for the determination of a particular subclass of antibody, e.g., IgA, IgE, IgM, etc,, are disclosed,  The method utilizes a piezoelectric oscillator having bound to the surface thereof an antigen specific for the antibody being determined.  The antigen-coated oscillator is exposed to a solution containing an unknown amount of the antibody.  After the antibody in the solution has attached to the antigen on the oscillator, the oscillator is exposed to a substance (sandwiching substance) which selectively binds to a specific subclass of the antibody being determined.  The frequency of the oscillator is measured before and after exposure to the sandwiching substance.  The change in frequency is related to the amount of the subclass of antibody bound to the oscillator, and the amount of the subclass of antibody in the solution can be quantified by reference to a standard curve.

Hydraulic liquid outlet passage means, providing a flow passage between the front and rear heads, are formed in the housing such that control valve means in the rear head can affect the flow of the liquid or oil from the sump to the expansible chamber, causing the modulating piston to vary the angle of the wobble plate mechanism and thus the pumping capacity of the compressor.  A generally spherical guide shoe is mounted in an axial shiftable manner on a guide pin projecting radially from the wobble plate with the spherical shoe slidable between a pair of opposed cylindrical guides whereby a line contact is maintained between the spherical guide shoe and the cylindrical guides to prevent rotation of the wobble plate element while permitting angular movement thereof relative to  the drive shaft.
