Abstract: FURNACE CONTROL USING              INDUCED DRAFT BLOWER, EXHAUST GAS                    FLOW RATE SENSING AND                    DENSITY COMPENSATION                  Abstract of the Disclosure An induced draft combustion apparatus and its associated control system has a blower located in the exhaust stack or vent which is used to induce the movement of air and combustion products into, through and out of the com-bustion chamber.  A flow-restricting orifice in the exhaust stack near the blower causes a region of higher pressure to exist upstream from the orifice with a region of lower pressure downstream from -the orifice.  An exhaust gas pressure signal representative of the exhaust gas volume flow rate is sensed on one side of the orifice and is fed back to a modulating gas valve which controls the outlet gas flow from the valve to be proportional to the magnitude of the exhaust gas volume flow rate.  By controlling blower speeds and exhaust gas volume flow capacities as related to a selected orifice size, various firing rates for the furnace can be selected, from the design maximum down to various derated levels.  Temperature-sensitive devices cooperating with the stack orifice or with the modulating gas valve are employed to compensate for changes in the density of the exhaust gas which accompany startup and changes in firing rate.

Abstract: RELEASABLE LOCKING WALL MOUNTING          Abstract of the Disclosure A wall mounting bracket for a telephone or similar item has an upward and forward facing support web, a downward facing lower web, and two flanges, one extending upward from the top of the support web and the other extending downward from the rear edge of the lower web, the flanges in a common plane and providing attachment means for mounting the bracket on the wall or other surface.  Two keyhole apertures are formed in the support web, spaced apart laterally, each having a circular portion and a slot, the slot below the circular portion.  A spring strip extends across the rear surface of the support web and is attached thereto, with a lower edge of the strip approximately coincident with the conjunction of circular portions and slot of each aperture.  The ends of the strip can deflect away from the web when a headed member is pushed through each circular portion of the apertures, the ends springing back when the headed members are moved down into the slots of the apertures, locking the headed members in position.  Manual deflection of the strip ends releases the headed members for removal.

Abstract: METHOD AND APPARATUS FOR HEAT  TREATING STRUCTURAL MEMBERS                    Abstract of the Disclosure The present invention relates generally to an improved method and apparatus for induction heat treating and re-straint quenching structural members of carbon steel, to a uniform martensitic structure, such that distortion of the member due to rapid quenching is controlled to a minimum. More specifically, the member is generally heated by induc-tion in two stages generally to austenitizing temperature in the range of 1450° to 1750°F. Then the member is liquid quenched under restraint to below 1000°F. to minimize dis-tortion and finally tempered under restraint at a tempera-ture in the range of 750° to 1250°F.  Such structural mem-bers attain minimum physical properties after heat treat-ing in the range of 110,000 psi yield strength and 125,000 psi tensile strength.

Abstract: Abstract A rivet bucking tool (10) is provided with a damping piston (13) actu-ated by air pressure in a damping chamber (42) of the tool housing (11) of sufficient volume to isolate the housing (11) from undesirable vibration. The piston (13) forms an assembly with a bucking die (23) so as to inertially restrain recoil jointly therewith. A pressure re-duction valve (28) is provided on the tool (10) for selectively setting the pressure in the damping chamber (42) to produce an elastic force bias on the assembly approximately equal to the optimal manual bucking force required for properly forming the rivet head and bucking in the riveting work at hand.

Abstract: ABSTRACT        A two-wavelength I.R. pyrometer is described which is suitable for monitoring the rapid heating of materials by C.W. lasers or electron beams.         The I.R. radiated from the material is separated into two closely adjacent wavelengths and signal values are obtained representative of those wavelengths.  Those signal values are then processed through an electronic circuit where the signal value of one of the signals is held substantially constant by a feedback control whilst the other signal value is influenced by approximately the same feedback control applied to the first signal value and wherein the resultant signal values are then processed through a ratio providing means to provide a ratio of one signal value divided by the other.  This is then a measure of the temperature of the material.

Abstract: ABSTRACT     In the casting of a concrete element, such as a column support block, in which there is used a mould core designed to produce one or more recesses or grooves in the element, the mould core is provided with one or more apertures or slots, in each of which there is arranged a recess-forming mould part which can be moved in said aperture or slot by means of a ram. Prior to a casting operation, the moveable mould part is moved to an outwardly projecting active position and, subsequent to the cast element hardening, is withdrawn by means of the ram, thereby to enable the cast element and the mould core to be separated from one another. All of the moveable core parts on one side surface of the mould core can be arranged on a plate extending parallel to the corresp ponding side surface of the mould core and arranged to be acted upon by the ram.      The invention also relates to a mould core provided with apertures or slots for moveable mould parts, the mould parts being arranged for movement by means of a ram between an active, casting position and an inactive position in which the cast element can be removed from the mould core.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved tobacco smoke filter is characterized by grooves defined in its outer periphery and extending to the smoke discharging end of the filter.  The grooves are total-ly exposed to ambient air along their entire length and serve as open air dilution passages to conduct air into the smoker's mouth with each puff or draw.   In one embodiment, the filter rod contains no plug wrap and is joined to a tobacco rod with tipping paper, the grooves being defined in both the tipping paper and the filter rod.  These grooves may be defined in the final assembled product by forming the grooves in the tipping paper and the filter rod at the same time.  Alternatively, the filter rod is pre-grooved and the tipping paper is attached thereto so as to conform to the grooves.  In another embodiment, the filter rod is wrapped with a suitable plug wrap which is either grooved simultane-ously with the rod or applied to conform to the pre-grooved rod; a short tipping paper ring is then applied to the joint between the filter rod and the tobacco rod.

Abstract: MERCHANDISE HOOK               ABSTRACT OF THE DISCLOSURE The disclosure relates to a display hook featuring a novel display system highly compatible with computerized inventory management under the Universal Product Code System. The display system provides labeling or product information in an easily accessible location, while allowing the labeling to be readily replaced and securely mounted at the same time. The display hook may also be used to display carded and/or bagged merchandise, with highly desirable safety features. The display hook is formed of a single, continuous wire-like element in an outwardly extending arm, carrying at its outer extremity a display element. This display element can hold labels of any desired size economically. A preferred embodiment of the display element is a mounting means, preferably a mounting plate, carried by the arm, at its forward extremity, upon which an attachment is mounted to form a plate-like label holder. The label holder serves importantly to provide for the display, at the forwardmost extremity of the unit, for easy scanning by computer input equipment, of a Universal Product Code label specific to the merchandise on display at the hanger. The mounting plate may be ribbed to hold a flexible, removable label securely. The label holder can also act as a guard means when the wire-like element is used in association with a lower outwardly extending merchandise supporting arm.
