Abstract: HIGH Q MONOLITHIC CAPACITOR WITH  GLASS-MAGNESIUM TITANATE BODY               Abstract of the Disclosure Monolithic capacitors having Q's of 3500 include copper electrodes buried in a non-reducible body of a crys-talline magnesium titanate phase and an intergranular glass phase.  The crystalline phase contains magnesium meta-titan-ate and/or ortho-titanate.  Magnesium di-titanate is exclu-ded from the body as are the oxides of lead, bismuth and cadmium, because such materials are reducible at the fir-ing conditions necessary to preserve the integrity of the copper electrodes.

Abstract: ABSTRACT OF THE DISCLOSURE:         A centrifugal casting machine has a first rotat-able shaft and a second rotatable shaft as well as a rotatable core member having a central opening, with at least one of these shafts being adapted for reciprocal movement so as to extend into the core member central opening and adjacent to the other one of the shafts. First and second mold halves are located on opposite sides of the core member and each is adapted to move inwardly and outwardly between open and closed positions.  The mold halves are rotatably supported on bearing means and in closed position are adapted to rotate with the core member and define a cavity in combination therewith.  The improve-ment takes the form of the addition of mold isolator means between the bearing means and the mold halves.  The iso-lator mechanisms serve simultaneously as torque couplings, clamping force transmitters, misalignment adjusters, vibration dampers and thermal expansion providers.

Abstract: IMPROVEMENTS IN OR RELATING TO PRESSURE FILTERS ABSTRACT OF THE DISCLOSURE          A tube pressure filter comprises (a) a pair of generally coaxial inner and outer tubular assemblies, which define between them a chamber of annular cross-section, (b) an impermeable elastic sleeve which divides said chamber into non-intercommunicating inner and outer compartments, (c) a filter element,(d) a slurry inlet extending annularly around one of the tubular assemblies for feeding a slurry to said inner compartment, (e) a hydraulic fluid inlet/outlet for feeding hydraulic fluid to and withdrawing hydraulic fluid from the outer compartment, (f) filtrate discharge means for the discharge of filtrate which has passed through the filter element and through apertures in the inner tubular assembly into the chamber, and (g) means for effecting relative movement of said tubular assemblies from one to another of three operating positions of said tubular assemblies.  In the first operating position of said tubular assemblies the slurry inlet is in communication with said inner compartment but the inner compartment is otherwise closed whereby a slurry to be pressure filtered can be fed to the inner compartment via said slurry inlet. In the second operating position of said tubular assemblies said inner compartment is closed and said slurry inlet cooperates with means formed by or associated with the other one of said pair of tubular assemblies to isolate said slurry inlet from said inner compartment whereby said slurry  to be pressure filtered can be dewatered.  In the third operating position of the tube pressure filter said inner compartment is open so that particulate solid can be discharged from the inner compartment.

Abstract: ABSTRACT OF THE DISCLOSURE         A novel tamper-evident closure is taught for use in connection with a container having a neck portion having at least one thread, and an annular collar portion disposed below the neck portion.          The closure includes a one-piece plastic closure body including a top end wall and a cylindrical side wall, the cylindrical side wall including an internally-threaded upper portion, and a depending lower skirt portion.  The skirt portion includes an inwardly projecting bead adapted to engage the lower surface of the annular collar portion of the container when the closure is completely threaded onto the container.  The closure further includes a frangible portion disposed above the skirt portion, the frangible portion including a substantially transverse line of weakness and being in the form of a bridge means having a substantially uniform thickness circumferen-tially around the closure but being sufficiently thin and flexible so as to be capable of collapsing when the inwardly projecting bead passes over the annular collar portion of the container as the closure is being applied to the container.  The bridge means divides the cylindrical side wall to substantially aligned cylindrical side wall portions having substantially identical cross-sectional thickness above and below the bridge means.  Upon collapse of the bridge means, the cylindrical side wall portions above and below the bridge means can abut against each other, thereby to permit the closure to be applied to the container without fracturing the bridge means.  The bridge means is designed to fracture in substantially a transverse plane disposed above the annular collar portion of the container without causing fracturing of the skirt portion.  Preferably, the closure is made of plastic material.

Abstract: Abstract of the Disclosure A sensor arrangement is disclosed for detect-ing the presence of an axle of a rail vehicle in a short length of a track.  The arrangement includes a bridge coupled to and including resistances of the rail upon which the vehicle travels.  This bridge is unbalanced by wheels of an axle shunting resistance of the bridge with the bridge unbalance producing an output indicative of the presence of the axle.  Two such arrangements displaced rela-tive to each other will enable detecting the direc-tion of movement of the vehicle.  This sensor arrangement contains no electric components on the rail and is insensitive to interference from rail currents and electromagnetic rail brakes.

Abstract: 22.             Abstract A method of monitoring a glassware forming process Infra-red detector means (11, 12, 13, 14, 15, 16, 36) is used to provide a signal corresponding either to the presence or absence of hot glass at a selected position or positions in the machine.   The signal is examined at a selected time in the cyclic process of the machine to ascertain whether the signal corresponds to the expected condition of the infra-red detector means (11, 12, 13, 14, 15, 16, 36) at the selected time, and emergency action is initiated in the event that the signal does not correspond to the expected condition of the infra-red detector means (11, 12, 13, 14, 15, 16, 36). The method may be used to ascertain whether the correct number of parisons has been removed from a blank station of the machine, to detect whether parisons formed at the blank station have a length exceeding a predetermined length, or to detect whether the correct number of articles of glassware have been removed from a shaping station of the machine at which the parisons formed at the blank station (A) are shaped.

Abstract: ABSTRACT:       A colour selection electrode is suspended in the corner of the upright edge of the display window by means of flat resilient elements connected in the corners of the colour selection electrode.  The flat resilient elements are substantially perpendicular to the electron beams deflected towards the relevant corner. At the end remote from the colour selection electrode the flat resilient elements have a slot-shaped aperture which is partly covered by a plate having an aperture. Pins comprising studs are sealed in the corners of the upright edge of the display window.  Each pin is perpen-dicular to the associated flat resilient element.  The studs project partly through the apertures of the flat resilient elements with plates.  The flat resilient elements engage the studs without pretension.  The flat resilient elements are connected to the colour selection electrode so as to be substantially pivotable.  As a result of this the flat resilient elements upon expan-sion of the colour selection electrode do not deflect over their full length but pivot about the end connected to the colour selection electrode.  A wire spring us connected under tension between the colour selection electrode and the end of each flat resilient element remote from the colour selection electrode.  The wire springs ensure that the flat resilient elements are urged on the studs so that after the occurrence of vibrations the flat resilient elements again return to their origi-nal position.  Instead of an aperture in the flat resilient element and a sealed pin with a stud in the up-right edge of the display window, according to another embodiment the flat resilient element may have a stud and a supporting element having an aperture may be sealed in the corner of the upright edge of the display window.
