Abstract: Abstract of the Disclosure A shock absorbing apparatus for earth boring drilling is disclosed herein.  The shock absorber is of the type having telescoping members with a sealed chamber containing pressurized fluid between the members for supporting load and absorbing shock.  The members have axial passages for the passage of high pressure air to the bottom of a borehole to remove cuttings.  A tube is connected to one of the members and inserted in telescoping relationship into the axial passage of the other member to transmit the circulating air.  The seals of the tube are protected from the heat of the circulating air by a liner disposed concentrically in the tube.  The liner is cylindrical and of lesser diameter than the inner diameter of the tube to create an annular air space for thermal insulation.

Abstract: ABSTRACT OF THE DISCLOSURE              This invention relates to a panel carrier and to a panel construction incorporating such carrier suitable for form-ing or cladding walls, ceilings, and the like.   According to one aspect of the invention, there is provided a carrier for panels comprising: an elongated, deformable, strip-like base; a plurality of panel engaging elements connected to and extending outwardly from the base in spaced apart relation therealong; each said panel engaging element including a pair of panel engaging prongs, the element being constructed such that the distance be-tween the prongs of each said pair remains substantially fixed regardless of deformation or flexure occurring in those portions of the strip-like base extending between the panel engaging elements. By deforming or flexing the strip-like base in those portions between the panel engaging elements, the carrier can be made to follow the contour of the base or support to which the carrier is fixed without, at the same time, influencing the distance between the panel engaging prongs of the respective panel engaging elements.  Thus, the panel engaging prongs are always capable of coming into the same secure engagement with the panels regardless of the contour of the support to which the carrier is fixed.  The invention in a further aspect provides a panel construction comprising a plurality of carriers as described above, the carriers being arranged with their strip-like bases in spaced generally parallel relation with the panel engaging elements of the several carriers lying in respective straight line paths extending generally transversely to the elongated bases of the carriers.  The construction includes a plurality of elongated panel members each of which lies in a respective one of the straight line paths and is engaged with the prongs of the panel engaging elements.

Abstract: ABSTRACT.               The invention relates to a high-pressure sodium-vapour discharge lamp having substantially the same colour temperature as an incandescent lamp.  The invention provides a high-pressure sodium-vapour discharge lamp having a low re-ignition voltage.                 This is achieved by including xenon and mercury in the discharge tube    such that (i) the weight of mercury is between 50% and 90% of the combined weight of the mercury and sodium, (ii) the pressure of the xenon at room temperature is between 100 and 1000 torr, and (iii) the sodium vapour pressure is between 300 and 800 torr in the operating condition of the lamp.  The power consumed by such a lamp is typically one-fifth of that consumed by an incandescent lamp having the same light output.

Abstract: Abstract of the Disclosure An electronic telephone network suitable for use with two-wire telephone line includes a low-output dynamic microphone coupled to a preamplifier.  The output signal of the preamplifier is coupled through a first equalization network which is responsive to an equalization signal which is related to the DC line current to equalize the frequency and amplitude spectrum of the transmitted signal irrespective of the telephone line length or loss.  The output of the equalization network is applied to a line-driver amplifier, and as a first input to an electronic signal separator or hybrid.  The output of the line-driver is coupled to the two-wire line, and as a second input through the separator by way of an attenuator.  The output of the separator is coupled to a receive amplifier by way of a second equalization network which is also responsive to the equalization signal to equalize the frequency spectrum of the receive signal as a function of line length. The loss of the attenuator is selected to be equal to the gain of the line-driver thereby to isolate the transmitted signal and to pass the receive signal to the receive amplifier.  In a preferred embodiment, the equalization signal is the DC supply voltage derived from the telephone line itself.  The output impedance of the line-driver is lowered during transmit to reduce the sensitivity of the separator isolation and, therefore, the sensitivity of the sidetone signal.  The various circuits of the network utilize active loads and other circuitry to provide maximum transmit signal dynamic range even at low line terminal voltages.

Abstract: BAIT HOLDER     ABSTRACT OF THE DISCLOSURE           A holder for holding minnow-type bait com-prises a ring within which the head of the bait fish is adapted to have a wedged fit so as to expose a por-tion of the head extending forwardly from near the eyes of the fish.  A pair of elongated arms extend in substantial parallelism from the ring and are normally in engagement along opposite sides of the body of the bait fish.   Hooks at the ends of the arms pierce the body of the bait fish for maintaining the head of the fish within the ring.  A passage extends laterally through one of the arms adjacent the ring through which the fishing line can be threaded after passing through the ring.  There is a passage near the trailing end of one arm through which the fishing line can then be threaded for maintaining the one arm in substantial parallelism with the line, so the line is offset rela-tive to the fore and aft axis of the bait fish and the bait fish moves in a rolling and side to side action when the holder is pulled through the water.

The above new 17,21-diesters possess considerable advantages over 21-monoesters and 17-monoesters of hydrocortisone, as well as over halogenized corticosteroids.          They possess good chemical stability and thus are particularly suitable for use in preparations for topical application when produced in a dissolved form.  They possess valuable therapeutic proper.ties such as a good antiphlogistic effect combined with a low toxicity and thus do not produce certain undesired  side effects typical in many corticosteroids.

Abstract: ABSTRACT OF THE DISCLOSURE An improved operator for a high-voltage switch. Prior art operators have a drive member connected to the switch for operation thereof. Immediately after the switch is opened, the drive member is held by a first latch and a spring is automatically charged to bias the drive member to close the switch. When the first latch selectively releases the drive member, it moves to close the switch. Immediately thereafter, the drive member is again held by a second latch and the spring is automatically charged to bias the drive member to open the switch. When the second latch releases the drive member, it now moves to open the switch. In prior art operators,; the latches sometimes fail to immediately hold the drive member rendering ineffective attempts to recharge the spring. A control system is provided which permits charging of the spring only If the respective latches hold the drive member following a switch operation. The system also reinitiates the prior charging of the spring if, after the drive member moves to operate the switch, the respective latches do not hold the drive member. Reinitiation of the spring charging holds the drive member until the latches succeed in holding it.
