Abstract: ABSTRACT OF THE DISCLOSURE      An  artificial  lifting device has a downhole valve which intermittently directs operating gas to the top of a collection chamber to promote the lifting of oil below the valve  upwardly  through  an  annulus  defined  between  a cylindrical housing supporting the valve and an external cylindrical member through which the housing extends.  Gas is alternately injected to the top of the chamber through an injection port and vented to the surface through a vent port.   An exhaust conduit,  separate from the source of pressurized gas running from the surface to the valve, communicates  the  vent  port  with  the  surface when  the device is in the vent mode.

Abstract: APPARATUS FOR MONITORING CHEMICAL REACTIONS          ABSTRACT OF THE DISCLOSURE         Apparatus for monitoring chemical reactions occurring on a slide, cartridge or other reflective carrier in which the nature of the reaction is determined quantitatively by means of a change in color.  The reaction products are illuminated by radiant energy of a known wavelength and the reaction is detect-ed and/or monitored by the reflection of the radiant energy from the sample where the reaction is occurring.  A plurality of samples carried on such slides is disposed in alignment in a circle or a line and a rotor or carriage carrying plural photometers or a single photometer producing plural beams at different wavelengths is moved relative to the samples, the beams being directed at the samples.  Each sample is scanned at least once as the carriage moves or the rotor rotates and the reflected radiant energy is captured by photo-responsive devices and channeled to a computer where the data is processed and information acquired concerning the respective samples with regard to end points and kinetic characteristics of their reactions.

Abstract: ABSTRACT       A mid-sole assembly mouldable into the rubber sole of an article of protective footwear is described.  The assembly includes a metallic puncture-proof protective mid-sole member which conforms generally in plan and elevation to the footwear sole and an insulative mid-sole member atop the protective mid-sole member.  The insulative mid-sole member is formed from cellular polyethylene, polypropylene, or other suitable relatively firm plastics material, and serves to insulate the interior of the footwear both ther-mally and electrically from the exterior thereof underneath the sole.  The two mid-soles may be assembled together be-fore being moulded into the sole and they may also be secured to a moulded heel filler member prior to sole moulding.  The insulative mid-sole member also acts as a filler, reducing the amount of rubber required for the sole.   The insulative properties provide additional comfort and protection to the footwear wearer.

Abstract: 9D-RG-14742-Payne/Chou PROTECTIVE METHOD AND CIRCUIT ARRANGEMENT FOR APPLIANCE    INCORPORATING SHEATHED HEATING ELEMENT                     ABSTRACT OF THE DISCLOSURE           A protective control arrangement for heating units of the type comprising the concentric assembly of a resistance heating element embedded in an insulating material and enclosed within a metallic sheath for limit-ing the propagation of a rupture in the sheath resulting from an arc at a discontinuity in the heating element along a substantial portion of the length of the sheath.  The control arrangement of the illustrative embodi-ment includes a power control triac operatively connected to the heating element for selectively coupling the heating element to an external power supply.  A preprogrammed microprocessor operatively connected to the gate terminal of the triac is effective to periodically interrupt power to the heating element by opening the switch means for interrupt periods of pne-determined duration. The time between successive ones of these interrupt periods is determined such that extinction of any arc which may develop at a discontinuity in the heating element occurs before any resultant separation can propagate along a substantial portion of the sheath; and the duration of each of these interrupt periods is at least approximately equal to the nominal recovery time for the insulating material required to allow the insulating material to return from its relatively low resis-tance molten and plasma state to its relatively high resistance state. By periodically interrupting energization of the heating unit in this manner, any arc which occurs is extinguished by the next occurring inter-rupt period.

Abstract: ABSTRACT         METHOD OF INSPECTING TRANSPARENT RODS       Various techniques for examining the core region of optical fibres and fibre preforms involve placing a portion of the fibre preform in an index-matching fluid and transversely illuminating the immersed portion.  As described herein, the need for an index-matching fluid can be eliminated by illuminating the fibre preform (12) with a diverging beam (14).  By the suitable selection of parameters, refraction at the air-fibre/preform interface can produce a well colliminated beam within the core region (11).  The diverging beam (14) can be produced by means of a cylindrical rod lens arranged parallel to the fibre/ preform 12.

Abstract: ABSTRACT          A method and apparatus are disclosed for increasing vertical resolution of television by modulating vertical deflection of the camera scanning beam a significant number of cycles per line, and modulating the vertical deflection of the receiver display beam in phase with the modulation of the camera while producing the video signal transmitted.  The receiver is provided with its own modulating oscillator operating at the same stable frequency as the modulating frequency of the camera, and phase synchronized by information transmitted by the camera.  The amplitude of modulation is adjusted for each undulating line to optimally intrude the area of adjacent lines of a frame without crossing or touching.  In the case of NTSC color television, the vertical deflection modulating oscillator of the camera is the color modulating oscillator, and the vertical deflection modulating oscillator of the receiver is the oscillator used for color demodulation phase synchronized by color bursts gated during blanking periods of each frame.  A frequency doubler is employed for modulation of vertical deflection in both the camera and the receiver in order that, for a line scanning rate of 15.734 kHz, there will be 455 modulation cycles for each line.  Additional deflection coils are disclosed for both the camera and receiver modulation of vertical deflection, although in practice the modulation drive for the camera and/or the modulation sync for the receiver may be electronically combined with the vertical and horizontal deflection signals applied to their respective yokes.  This technique for increasing vertical resolution can be practiced with other equipment and other standards, such as PAL and SECAM.

At such stations pipe is transferred between containers and the load crane. Moreover, a center of gravity alignment feature at such stations balances pipe in the containers. A footer support system reinforces the storage facility floor where containers are placed thereby minimizing overall floor carrying capacity requirements.
