Abstract: PHN.8206 9.6.76 ABSTRACT:           A method of manufacturing a colour television display tube. On the window portion of the tube an electron-absorbing layer is provided which is scanned by means of an electron beam via the shadow mask. The charge image on the layer is then developed xerographically. The layer is preferably photoconductive so as to be able to remove the charge remaining after the development by means of a uniform exposure.

Abstract: ABSTRACT OF THE DISCLOSURE    An uncharged positive-electrode composition contains particulate lithium sulfide, another alkali metal or alkaline earth metal compound other than sulfide, e.g. lithium carbide, and a transition metal powder.  The com-position along with a binder, such as electrolytic salt or a thermosetting resin is applied onto an electrically con-ductive substrate to form a plaque.  The plaque is assembled as a positive electrode within an electrochemical cell opposite to a negative electrode containing a material such as aluminum or silicon for alloying with lithium.          During charging, lithium alloy is formed within the nega-tive electrode and transition metal sulfide such as iron sulfide is produced within the positive electrode.  Excess negative electrode capacity over that from the transition metal sulfide is provided due to the electrochemical reaction of the other than sulfide alkali metal or alkaline earth metal compound.

Abstract: ABSTRACT OF THE DISCLOSURE     A safety control circuit for an electrically oper-able machine such as a punch press is described.  The cir-cuit includes input means for delivering electrical power to the machine and first and second relays, each including switching means and an associated relay coil for operating said switching means.  The switching means of the relays are connected in said input means so that electrical power is delivered to the machine only when both relay coils are energized.  First and second capacitors are associated re-spectively with said first and second relay coils and a source of direct current is provided for charging the capa-citors.  The direct current source is connectible with both capacitors through said switching means of said relays when both relay coils are de-energized, so that the capacitors are both normally charged when the circuit is at rest.  First and second machine activating switch means are associated respectively with said first and second capacitors.  Each of said switch means is arranged, when operated, to connect the relevant one of said capacitors with the associated relay coil to cause the capacitor to discharge into the coil and operate the relay.  The circuit also includes resistor means connectible with either of said capacitors through the switch-ing means of the relays, said switching means being arranged in the event that only one of said machine activating switch means is operated, to connect the capacitor associated with the other switch means to said resistor means, whereby, in use, the relevant capacitor will progressively discharge into the resistor means, preventing energization of the associated relay coil and hence activation of the machine after the level of charge in the capacitor has fallen below that required to energize the associated relay coil.

According to the process of the present invention, there can be obtained the desired pyridine bases in high yield, whereas formation of by-products including high boiling point pyridine derivatives is remarkably suppressed.  The catalyst employed in the present process has a high resistance to the reaction atmosphere.  Pyridine bases are important solvents and valuable intermediates for use in the product of dyes, medicines and agricultural chemicals.

Abstract: ABSTRACT OF THE DISCLOSURE             Methods and apparatus for roasting a product with a heated granular bed are disclosed. A granular bedding, heat transfer material such as salt or the like contained within a rotatable heating chamber is directly exposed to a heat source which directs heat into  the interior of the heating chamber. Heated granular material is then conveyed to a separate product roasting chamber and mixed with incoming particles of a product to be roasted. Internally disposed auger and flighting means facilitate movement of the commingled granular material and product through the roasting bin in response to rotation thereof. Separation means at the output of the roasting bin separates the processed product from the granular heating medium, and continuously returns the granular material to the heating bin for repetition of the process cycle. In one form of the invention the heating chamber is coaxially disposed internally of the rotatable roasting chamber to maximize thermal effi-ciency. In an alternative embodiment, commingled product and granular material are heated together in a rotatable chamber.

Abstract: METHOD FOR RETAINING A RING IN ASSOCIATION WITH A BODY MEMBER            Abstract of the Disclosure One or more radially projecting tabs are provided on a discontinuous ring for retaining the ring in proper association with a body member in spite of movement or vibra-tion of the assembly.  The tab, or tabs, mate with a grooved section of the body member.  The groove may comprise a thread.          The ring may be internal or external to the body member.  The retaining tab will project radially outward or inward when the ring is to be internal or external, respectively, to the body member.  The tabs have an axial thickness of the order of 25 percent, or less that of the ring.  To provide secondary in-ternal retaining means, a portion of the ring may be cut from an oversize ring so that a stress is formed when the ring is closed for inserting the ring in an internal opening.  When a ring is to be used external to a body member, a simple cut may be made in an undersize ring so that a stress is formed when the ring is opened for placement external to the body member. The ring may be fabricated from any suitable material includ-ing:  metal, plastic, or an elastomeric material.  When the ring is made of appropriate material and cut at an appropriate angle, it may be used as a seal.

Abstract: BREATHING APPARATUS              Abstract of the Disclosure A portable breathing apparatus for use in a noxious atmo-sphere includes a helmet that is closed except for a bottom opening that is provided with a neck seal to permit the helmet to be slipped over the head of the wearer while sealing the open bottom of the helmet to provide an airtight enclosure about the wearer's head.  A backpack includes a high pressure oxygen cylin-der, that is connected to a regulator valve through a pressure reducer; and a carbon dioxide scrubber, that receives expiration gas from the helmet through an exhaust breathing line which connects to a flexible reservoir which collects the majority of expired gases and which is provided with a relief valve to protect the bag and limit expiration resistance.  The outlet of the reservoir is connected to the inlet of the scrubber and the outlet of the scrubber being connected to a second inlet in the regulator valve by a line that includes a heat exchanger asso-ciated with the oxygen cylinder so that the oxygen cylinder removes heat from the recirculating gas from the carbon dioxide scrubber.  The regulator valve has an outlet chamber connected to the helmet interior through an inlet breathing line and the regulator valve includes an on-off-type valve that delivers oxygen from the oxygen supply to the chamber through an injection nozzle only when inhalation by the wearer causes a pressure drop in the chamber that acts on a diaphragm to open the valve,  The gas from the scrubber enters the chamber in a reduced pressure zone adjacent the nozzle outlet, the reduced pressure helping to pull scrubbed gases from the carbon dioxide scrubber.
