Abstract: ABSTRACT         A transistorized keying circuit is described which provides for both polar and neutral interfacing. The circuit comprises an oscillator, an AND gate, an exclusive OR gate, a transformer, and two similar output circuits each of which is connected to the secondary of the transformer.  The oscillator produces a high frequency binary output signal having an asymmetric duty cycle.  The output of the oscillator and a low frequency data signal are applied to the AND gate.  The output of the AND gate and another low frequency data signal are applied to the exclusive OR gate whose output is amplified and applied to the primary of the transformer.  Each output circuit coupled to the secondary of the transformer comprises a switching transistor for switching a supply voltage onto a. transmission line and a peak detector for controlling the operation of the switching transistor.  When the AND gate is enabled and the output signal from the exclusive OR gate is the oscillator output signal, only one of these transistors is switched ON; and when the output of the oscillator gate is the inverted signal only the other transistor is switched ON.  When the AND gate is disabled, neither transistor is switched on.  For polar operation of this circuit, the opposite end of the transmission line is connected through a load resistor to voltage supply common.  For neutral operation either the AND gate can be enabled and disabled or the load resistor can be connected to voltage supply positive or negative.

Abstract: ABSTRACT            A surface acoustic wave filter includes a length-weighted interdigital transducer (T1)  to one side of which there are provided bus bar parts (BP1, BP2) which are within the acoustic aperture (A), which are inclined at an acute angle to the propagation path (P) and which closely follow the major lobe (L1).  The bus bar parts (BP1 and BP2) each have a width (W) along the propagation path (P) defined by 2W=n .lambda./2 where n is an odd integer and .lambda. is the wavelength of surface acoustic waves at substantially the maximum amplitude response frequency of the transducer (T1).  In this case the components of the surface acoustic waves reflected from the two edges of each inclined bus bar part (BP1 and BP2) along the propagation path (P), that is to say the component reflected waves (SW1) reflected from the edge closest to the overlap envelope and the com-ponent reflected waves (SW2) reflected from the edge which forms part of one end of the transducer, are in antiphase at that maximum response frequency and so spurious signals due to the component reflected waves (SW1 and SW2) at that frequency are substantially suppressed.

Abstract: ABSTRACT OF THE DISCLOSURE        Self-sustaining, dimensionally stable, axially elon-gated fibrous bodies of suitable cross-sectional size and shape for use as cigarette filters are produced from a bondable continuous filamentary tow of substantially con-tinuous thermoplastic fibers.  The fibers within the filter body are oriented in an adjacent and overlapping relation to one another in generally successive layers extending generally transverse to the longitudinal axis of the filter.  During fabrication the filter is passed through a cooling station of reduced cross-section so that the radially peripheral edges of the fibers are bent backward and overlap to form a smooth peripheral surface to which tip-wrap material can readily adhere without the need for a plug wrap or for coating the filter.

Abstract: IMPROVED JET NOZZLE ASSEMBLY FOR THERAPY BATHS     ABSTRACT     An adjustable nozzle assembly primarily for controlling the direction of a water-air jet of the type commonly found in whirlpool or therapy baths.  The assembly comprises four components, namely, a pair of threaded flanged fittings, an eyeball shaped nozzle having a cylindrical channel therethrough, and a retaining ring for securing the eyeball nozzle in one of the threaded fittings.  The two fittings are of cylindrical construction adapted to be concentric to each other.  An outer fitting has threads along both the internal and external cylindrical wall thereof.  The external thread is adapted to mate the outer fitting with a suitable source outlet pipe.  The inner thread of one outer fitting is designed to mate with the corresponding outer thread on the inner fitting which tightens down concentrically therewith.  The two fittings have overlapping annular flanges, the flange of the inner fitting being slightly larger than the flange of the outer fitting to provide a smooth continuous finished appearance when the assembly is fully installed through a suitable aperture in the wall of a tub.  The aperture of the eyeball nozzle through which the water-air Jet exits is designed to terminate substantially in the plane of the inner fitting flange to avoid protrusions which would otherwise create a likelihood of injury to the user.  The four components of the present invention are of unique but simple structure which may be manufactured from molded plastic and assembled together without the use of hardware.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention deals with a filter for gas or liquid separation. The filter consists of a continuous fiber tissue within which a granular or powder formed (particle formed) activated material is contained (fixed). The activated material shall have the ability to absorb or chemically bind specific gas or liquid formed components. The fibre tissue is in itself sufficiently porous to permit the said gas or liquid components to diffuse in through the same, while at the same time being sufficiently compact to keep  the activated particle formed material fixed.          The filter is primarily intended to be used in such a way that the flow of gas or liquid to be purified passes the fibre tissue in thin layers whereupon the relevant components can diffuse in through the pores of the fibre tissue in order to be bound or absorbed in the particle formed material.

Abstract: ABSTRACT.            A method of, and apparatus for, generating a unique index mark from the commutation signal of a d.c. brushless motor.   A unique index mark is provided to avoid errors in addressing a memory location on a disk surface by corre-lating the commutation signal from a d.c. motor with a synchronising signal present on one or more discrete tracks of the disk.   The proportion of the synchronising signals on one track depends on the number of phases of the d.c. motor although typically with a 2-phase motor one-half of the track contains the synchronising signal, the other half of the track being erased.   The commutation signals and the synchronising signals are correlated using a microprocesser and a flip-flop.   A sensing head looks for a synchronising signal which is typically 10 individual data blocks of short duration. The detected blocks are counted in each half revolution of the disk, timed from the index edge and comparing the counts in successive half-revolutions in a comparator over several disk revolutions.   The microprocesser then identifies from the comparator output the half-revolution of the disk in which the synchronising signal was recorded. The microprocesser receives the output of the comparator and forces the output of the flip-flop hi setting an initial condition.   Thereafter the microprocesser ensures that the flip-flop output is always correlated with the synchronising signal thereby producing a unique index mark.

Abstract: PUMP NOISE FILTERING APPARATUS FOR A BOREHOLE MEASUREMENT WHILE DRILLING SYSTEM  UTILIZING DRILLING FLUID PRESSURE SENSING Abstract of the Disclosure An apparatus for removing pulsation noise caused by a well drilling fluid circulating pump from fluid pressure pulse transmitted measurement while drilling data passing through drilling fluid in a drill string of a borehole measurement while drilling system.  The noise filtering apparatus includes a drilling fluid pressure sensor and an adaptive estimator that memorizes the pulse noise signature of a pump in synchronization with the pump's strokes.  The memorized signature is removed from the signal data derived from pressure pulsations in the drilling fluid in order to remove or filter the pump's noise or pressure signal disturbing influence from this data.  The adaptive estimator is arranged such that it will compensate for changing operating conditions of the pump so that this pump created noise is substantially, continuously filtered from the measurement while drilling data.
