Abstract: ELASTIC BALE FORMING CONVEYOR FOR CYLINDRICAL BALES                 Abstract of the Disclosure In a mobile machine for forming cylindrical bales, a mat of crop material is picked up from the ground and fed to a bal-ing chamber defined by the generally horizontal upper run of a lower endless belt conveyor and the internal envelope of a plurality of rollers carrying an upper conveyor and disposed immediately above it.  The upper conveyor comprises a plurality of elastic endless belts stretched around the rollers and in-cludes a lower run which, at the inception of bale formation, spans the baling chamber between a pair of lower rollers im-mediately above the chamber floor.  The upper and lower conveyors are driven in opposite directions so that as the mat of crop material is fed into the baling chamber, it is rolled, spiral-like, into a cylindrical bale.  As the bale increases in diameter, the belts of the upper conveyor, engaging the bale periphery, extend elastically to provide the increase of belt length re-quired to accommodate the bale in the chamber.

Abstract: ABSTRACT OF THE INVENTION         An electronic flash accessory is provided for a camera of the type having a flash socket assembly adapted for receipt of a conventional multiple flash bulb array together with circuitry for sampling the terminals of the flash socket which are adapted to connect to the last flash bulb scheduled to be fired in the array and for providing a signal which operates to inhibit camera operation when the sampled impedance of the last flash bulb scheduled to be fired is substantially different from the impedance of an unfired non-defunct flash bulb.  The electronic flash accessory includes circuitry responsive to a predetermined event relative to the readying of the flash accessory in expectation of the commencement of a photographic exposure cycle involving an artificially illuminated subject for simulating the impedance of an unfired non-defunct flash bulb in order to enable the camera to automatically perform a photographic exposure cycle upon actuation by the camera operator.

Abstract: "PROCESSES FOR THE PREPARATION OF                 CHLORINATED PHENOLS"                Abstract of the disclosure The invention relates to the batch or continuous para-chlorination of para-unsubstituted phenols, especially ortho-cresol, using sulphuryl chloride in the presence of one or more rate and selectivity catalysts, and to the avoidance of the reaction mixture going solid.  It concerns specifically the carrying out of the chlorination process in stages, each stage involving only part of the sulphuryl chloride needed for the chlorination and being carried to completion before there is added to the mixture the sulphuryl chloride for the next stage.          In addition, the invention concerns specifically the selection and control of reaction temperature, throughout the reaction, in order to minimize by-product formation and the likelihood of freeze-up.

Abstract: ABSTRACT:         An inductive load driving amplifier is disclosed which includes two serially connected transistors, with Zener diodes limiting the collector-emitter voltage of the one and diverting the collector-base current of the other when the first one switches off.  The driver is implemented as an integrated circuit.  This collector isolation consti-tutes a high voltage Zener diode which contributes to limit the collector voltages.  The combination of these features prevents the device from being exposed to second breakdown when switching highly inductive loads (e.g. several Henrys under SOV), thereby avoiding the harmful effects of break-downs during switching.

Abstract: METHOD OF MAKING CHISEL-TYPE CUTTER LINK                  Abstract of the Disclosure A method of cold-forming a substantially right-angle final bend in a chisel-type saw-chain cutter link.  The method involves the progressive, staged shifting of a bend, and of the inside and outside corners therein, in a cutter blank from a starting, greater-than-right-angle bend line toward an adjacent, substantially parallel, final substantially right-angle bend line.  Subsequent to the making of an initial bend in a blank, the making of later shifted bends is accompanied by the flowing of material in the blank toward the region of the later-produced bends.

Abstract: A FILM WEB HANDLING MECHANISM     Abstract of the Disclosure A film web handling mechanism includes a motor for driving the mechanism, and an endless belt for transferring the motor drive to a supply pulley, a take-up pulley and a shutter-shuttle drive pulley.  The supply pulley and the take-up pulley are connected, through a supply clutch and a take-up clutch to a supply spindle and a take-up spindle.  The endless belt is driven in one direction only by the motor, however, the supply and take-up spindles are capable of moving the film web in both a forward and reverse direction.  The forward and reverse direction capability of the supply and take-up spindles is accomplished by varying the amount of motor drive transferred to the spindles through the clutches.  By means of a single control knob linked to the supply clutch and to the take-up clutch, an operator is able to select a mode of operation.

Abstract: A B S T R A C T          An in situ oil shale retort having boundaries of un-fragmented formation and containing a fragmented permeable mass of particles containing oil shale is formed in a subterranean formation containing oil shale.   A base of operation is excavated at a working level in the formation above the site of the retort to be formed and means are excavated through the formation for providing access to a location underlying the base of operation and at the bottom of the retort site.   In one embodiment, a void, for example in the form of a vertical slot, is excavated in the formation between the means for access and an elev-ation below the bottom of the base of operation, leaving intact between the top of the void and the bottom of the base of operation a horizontal sill pillar of formation with a vertical thickness sufficient to maintain a safe base of operation after explosive expansion of formation towards the void to form the fragmented permeable mass of particles.  The fragmented particles are retorted to recover shale oil and gaseous products therefrom.

Abstract: Abstract An in-line heater for fluid moving in a conduit has a thermally conductive and thermally massive body with a fluid passage in it.  A heating element is located in the body proximate only the upstream portion of the passage.  The downstream portion of the passage is in heat exchange relationship with the body but is heated substantially less by the heating element than is the upstream portion.  This downstream portion of the fluid passage acts to damp cycling variations and overshoot and undershoot of the temperature of the fluid at the outlet of the heater.

Abstract: ABSTRACT       A method of lubricating a section (usually curved) of rail of a railway track subjected to wear by the wheel-flanges of passing railroad vehicles involves intermittently propelling discrete pellets of lubricant horizontally force-fully against an inner side surface of the rail section. The shots of lubricant may be controlled by using a signal voltage applied between the rails or by means of an electric transducer, an inductive transducer, a clock or the like. Compressed air and/or lubricant is applied to a metering dispenser from separate storage containers arranged at a distance from the dispenser which is horizontally spaced from an inner side surface of the rail section.  The lubricant pellets are propelled with such force as to ensure that the lubricant contacts the surface even in the presence of normal obstacles such as ice and snow.
