Abstract: DRILL PIPE HANDLING MECHANISM             ABSTRACT OF THE DISCLOSURE      A drill pipe handling mechanism for a drilling rig includes spaced apart upper and lower arms mounted on a shaft which is mounted for pivotal and limited axial movement with respect to an axis which is spaced from and parallel to the drilling axis.          The lower arm includes a receptacle for the lower end of a drill pipe section.  The upper arm includes a drill pipe holder having a power actuated movable gate section.  A drill pipe retainer is pivotally mounted on the shaft above the pipe holder and is operated by a separate power actuator.  Opposed power actuated pipe gripping and holding wrenches are disposed on the lower part of the rig mast for gripping and holding a drill pipe section while threaded joints are broken loose by a rotary head connected to the upper end of the drill string.  A power actuated wrench is mounted for pivotal movement into pipe gripping position for breaking loose threaded joints which cannot be loosened by the rotary head.

Abstract: ABSTRACT          A structure for mounting an LED detachably adjacent an end of an optical fibre is described.  The LED is incorporated in a package comprising a base having a recess at one end and a flange at the other.          The LED is housed in the recess and no part of the LED or associated leads protrudes above the top surface of the base.  A receptacle has a through passage formed with a wider portion at the bottom end thereof. The LED package is inserted in the wide portion with the flange abutting the lower surface of the receptacle.  An optical fibre is inserted into the narrow portion of the passage from the top until the ground end of the fibre abuts the upper surface of the LED package, the fibre then being secured in place by an encircling nut which threadably engages the receptacle.  Because the fibre has a greater diameter than the recess in the LED package, the LED and other components in the process cannot be damaged by engagement with the fibre end.

Abstract: ABSTRACT OF THE DISCLOSURE             An arrangement is provided for limiting the pressure developed by the combination of gases of a gaseous mixture, such as hydrogen and oxygen in a closed container, for example, in a rechargeable battery.  The arrangement includes material having substantial heat capacity and having a high surface-to-volume ratio disposed in free spaces in the container wherein the hydrogen and oxygen may accumulate during the charging or discharging of the battery.  When the hydrogen  and oxygen combine to form a gaseous product or vapor at a high pressure, the gaseous product is cooled by the aforementioned material to limit the pressure to an amount below that capable of causing rupture of the container.           The material may further, in the case of a condensible vapor such as that formed by the combination of hydrogen and oxygen effect a temperature reduction which results in condensation of the vapor to further reduce the pressure to insure against rupture of the container.

Abstract: ABSTRACT      A moisture stripping device for non-evaporatively stripping moisture from a moving film such as a photographic motion picture film.  The film is cleaned in a liquid bath which has ultrasonic energy applied thereto.  The film leaves the bath and passes through an air nozzle which is supplied with a source of air pressure.  The air nozzle consists of a split block having a film slot extending through the block.  A plurality of air jets are conducted into the slot at opposite sides thereof.  The film, wet with cleaning solution, enters the slot and is non-evaporatively dried by air pressure which forms a moisture barrier at the lower edge of the slot.  The slot is only slightly wider than the thickness of the film, yet the film is protected from touching the sides of the slot by an air cushion formed by air jets directed at both sides of the film.          The air jets are formed by a plurality of air holes in the split block.  The holes conduct air from the air source to the film slot.  A relatively large pressure drop is provided across the air holes with the result that a uniform pressure is developed across the entire face of the film, preventing it from contacting the surface of the split block.  The slot has sharp edges at the lower side which receives film to maximize the moisture barrier effect.

Abstract: ABSTRACT           The present invention relates to the discovery that the administration of maltol or ethyl maltol at ap-propriate dosage levels and rates, significantly reduces the tobacco consumption of habitual smokers.  In a pre-ferred embodiment, finely divided ethyl maltol is distributed in a chewing gum base, which when chewed by the subject, results in a gradual release of ethyl maltol into the oral cavity.  When administered in appropriate amounts over a period of several days, there results a gradual decrease in the number of cigarettes smoked and the length of time they are smoked.  The reduction appears to be spontaneous and does not appear to be accompanied by the typical symptoms of nicotine withdrawal.

Abstract: ABSTRACT OF THE DISCLOSURE           A high efficiency system and method for supplying heat energy to a combustible effluent producing primary process, such as to a paint drying oven, in which the output of an incinerator-heater is controlled in order to be matched to the heat energy requirements of the process.  At the same time, the incinerator burner temperature is sufficiently high to incinerate the combustible effluent developed by the pri-mary process.  Effluent laden air is circulated from the process site through a preheat heat exchanger into which is transferred a portion of the heat of the incinerated air prior to entry into the incinerator chamber.  The incinerated air is recirculated to the process site in order to provide the heat energy requirements of the drying oven or other process.  A proportion of the incinerated air is vented to an exhaust stack via an air-to-air heat exchanger which pre-heats incoming fresh air circulated to the process site to make up the vented flow of incinerated air.  A temperature controller modulates the incinerator burner temperature, as well as the action of a bypass damper causing controlled bypassing of the preheat heat exchanger by the effluent laden air in order to match the heat output of the system to the requirements of the process.
