Abstract: Abstract of the Disclosure A bell and spigot pipe joint including a bell end having a  locked-in  sealing  gasket  and  a  thickened  cross-sectional configuration is disclosed herein.  A method and an apparatus for making  this  bell  end  with  its  thickened  cross-sectional configuration and with the sealing gasket locked in place are also disclosed herein.  In accordance with the present invention, the bell  end  is  formed,  its  cross-sectional  configuration  is thickened,  and  a  circumferential  sealing gasket  is  locked in place, all at approximately the same time and using one overall apparatus.  Thus in contrast with the prior art, the end of the pipe is not pre-thickened or post-thickened before the bell is formed thereon.

Abstract: A Noise-Reduced Movable Imprinting Deck Abstract of the Disclosure A noise-reduced imprinting deck is disclosed for use in a postage meter system.  The imprinting deck and the peripheral postage meter are mounted on a central frame member that is shock and noise isolated.  The connections between the movable deck and the central frame are noise-reducing leaf springs.  The leaf springs allow for a highly flexible deck movement, while eliminating relative movement between the deck and the central frame support connections.  It is the elimination of the relative movement between the deck support and the deck connections, which greatly decreases the noise output of the deck mechanism.

Abstract: METHOD OF MANUFACTURING POSITIVE   ELECTRODE FOR NONAQUEOUS CELL     Abstract of the Disclosure The present invention discloses a method of manu-facturing positive electrodes for nonaqueous cells in which manganese dioxide is used as positive active material and light metals such as lithium, sodium or aluminium are used as negative active material. The method comprises adding to manganese dioxide active material powder, a binder and a viscous agent solution decomposable at temperatures lower than the melting point of the binder, thereby to form paste, applying such paste to the supporting member, and heat-treating this paste-applied supporting member.  According to the novel feature, the heat treatment is conducted firstly at the decomposition temperature of the viscous agent in an oxidization atmosphere, and secondly at the melting point of the binder under vacuum or in an inert atmosphere, whereby loss of effective manganese dioxide during manufacture is decreased, thus permitting to improve the cell performance.

Title: Inductive load driver circuit effecting  slow hold current decay and fast turn  off current decay
Inventor: WEBER ROBERT E
IPC: F02D41/20
Filed: 1979-02-13
Granted: 1982-08-31
Abstract: ABSTRACT             An inductive load driver circuit comprising first and second switch means and high and low impedance load current decay means. For the duration of a load actuation signal the first switch means are responsive to the magnitude of the load current to complete and interrupt a first current path to the load to cycle the load current between first and second levels. The second switch means are enabled for the duration of the load actuation signal to complete a second current path to the load when the first switch means interrupts the first current path. When completed the second current path comprises the low impedance decay means allowing the load current to decay slowly from the first current level to the second level to provide during such slow decay a load current sufficient to maintain actuation of the inductive load. The end of the load actuation signal disables the second switch means to interrupt the second current path and thereby require the load current to decay rapidly through the high impedance decay means. In one embodiment, the second switch means comprise an SCR disabled by a final momentarily turn ON of the first switch means.

Abstract: ABSTRACT OF THE INVENTION           A method and apparatus that significantly increases the sensi-tivity and flexibility of laser optoacoustic spectroscopy, with reduced size.  With the method, it no longer is necessary to limit the use of laser optoacoustic spectroscopy to species whose absorption must match available laser radiation.  Instead, "doping" with a relatively small amount of an optically absorbing gas yields optoacoustic signatures of nonabsorbing materials (gases, liquids, solids, and aerosols), thus significantly increasing the sensitivity and flexibility of optoacoustic spectroscopy.  Several applications of this method are demonstrated and/ or suggested.

Abstract: ABSTRACT OF THE DISCLOSURE      Oxygen is incorporated into an FeTiMn granulate in an amount sufficient to form  double oxides of titanium and manganese therein, but insufficient to form oxides containing iron.  As the result the granules are embrittled, favoring the formation of microcracks to such an extent that activation of the granules by hydrogen takes place, after initial evacu-ation, at room temperature, after which the granulate can be used in a pres-sure container for storage and discharge of hydrogen and/or deuterium over long periods of operation.  The oxygen content is to be kept in an atomic ratio with reference to the manganese content of the alloy lying between 1:3 and 1:3.5 and the ratio of titanium not bound by formation of a metal oxide to the iron should be equal to or greater than 1:1 on an atomic basis, with the FeTi content of the alloy constituting 90 to 95% by weight of the alloy.

Abstract: Abstract:      An apparatus and method of setting a bead ring against the plies of a tire carcass on the shoulder of a building drum includes a carrier member with a retractable bead support flange.  As the carrier member pushes the bead firmly against the carcass plies, the bead support flange is also pushed against the carcass plies, and the flange partly retracts under the pressure.  Then, a fluid operated piston drives the support flange further away from the carcass plies, leaving the bead ring almost un-supported, but pressed firmly against the carcass plies on the building drum.  The carrier member then retracts away from the building drum, leaving the bead ring in place on the building drum shoulder and ready to have the carcass ply end portions wrapped around it.

Abstract: COLOR SWITCHING DISPLAY SYSTEM     Abstract of the Invention A deflection amplifier gain correction circuit for a beam penetration color cathode ray tube having a split high voltage anode in which the deflection waveform is shaped as a non-linear function of the final anode voltage and as a func-tion of a dynamic focus waveform used for the electrostatic focussing system in the cathode ray tube.  The shape of the correcting waveform is adjusted by adjusting the amounts of the dynamic focus waveform and the anode switching voltage waveform which are multiplied to produce a resulting waveform which varies as a function of deflection position and anode voltage and is summed with a waveform which is a non-linear function of anode voltage.  Such a system can be adjusted for each individ-ual display unit to compensate for production variations in a color penetration tube using two different colored phosphors.          By producing such registration for beams having different anode voltages, various mixes of colors can be produced to form, for example, four distinct colors on a display from two phosphors with color impurity being reduced by reduction in misregistra-tion of different colors at the edges of the cathode ray tube screen.

Abstract: PRESSURE PULSE DETECTION APPARATUS INCORPORATING NOISE REDUCTION FEATURE Abstract of the Disclosure An improved apparatus is disclosed for use in a measuring while drilling apparatus which forms a pressure pulse promulgated from a downhole location upwardly through the drill string and column of mud therein.  This apparatus includes a mud line section adapted to flow drilling mud in the mud flow line through an axial passage therein.  The apparatus includes an encircling bladder which receives hydraulic oil under pressure to inflate to choke the passage.  A Pitot tube is focused downstream and thus does not intercept the mud flow from the pump and the noise which is created by pump operation.  Mud pressure variations directed upstream from the measuring while drilling apparatus, however, are directed into the Pitot tube.  These pressure variations are coupled to a pressure signal transducer which forms an output signal of some type which is recorded.  Pump noise is nulled to a minimum.
