Abstract: Abstract of the Disclosure A system for propelling a vehicle which includes a frame within which at least one shuttle is mounted for recip-rocal movement along a linear path of travel.  An oscillating body is attached to the shuttle that is capable of delivering a series of alternating opposed force pulses to the shuttle with the pulses acting in a  direction generally along the shuttle's path of travel.  A rectifying means periodically locks the shuttle to the frame when the force pulses act in a first direction whereupon the forces are transmitted to the frame and unlock the shuttle when the forces act in the oppo-site direction, whereupon the shuttle is caused to move in the opposite direction.  A return mechanism is operatively connect-ed to the shuttle for restoring the shuttle to its original starting position after it has been driven a predetermined dis-tance over the path of travel.

Abstract: METHOD AND SYSTEM FOR REDUCING CONFERENCE BRIDGE OSCILLATIONS   Abstract of the Disclosure Undesired oscillations in a communications conferencing network are reduced and/or eliminated by frequency shifting signals passing through the conferencing network by a small amount for each pass therethrough.     Electrical information signals from a plurality of individual communication sets are individually summed, frequency shifted by a predetermined amount, and coupled back to individual ones of the communication sets, less their individual signal contributions.  Frequency shifting is performed on analog electrical information signals by modulating the sum signals, filtering the modulated signals and remodulating the filtered signals with a second carrier signal train having a frequency which differs from the frequency of the first carrier signal train by a predetermined amount, and filtering the signals resulting from the second modulating step.     Frequency shifting on digital information signals is performed by digitally expanding the spectral range of the sum signals to provide a plurality of replicas of the spectral content of the signals distributed over a wide spectral range, digitally filtering the expanded signals to filter out predetermined portions of the expanded range, digitally shifting the frequency of the remaining replicas by a second expansion, and digitally filtering the frequency shifted replicas to filter out unwanted portions of the shifted spectrum.

Abstract: 47,951I                 ABSTRACT OF THE DISCLOSURE Energy conserving incandescent lamp wherein the envelope has provided on the interior surface thereof a very efficient and economically applied heat mirror which is highly transmissive for visible radiations and highly reflective for infrared radiations, thereby to enhance the conversion  of  electric  energy  to visible  energy.   The heat-mirror coating comprises a two layer Ag/TiO2 or a three layer TiO2/Ag/TiO2 coating of predetermined thick-ness.  The three layer coating is formed by first applying to the envelope interior surface a thin layer of clear aliphatic alcohol solution having contained therein par-tially hydrolyzed metallic  alkoxide which substantially comprises titanium alkoxide, and which solution contains at most only a limited amount of selected mineral acid. The applied clear solution layer is heat treated to con-vert same to a thin continuous layer substantially com-prising titania.  A thin silver layer is applied over the first applied titania coating, preferably by vacuum metal-lizing, and a second thin layer of solution containing the partially hydrolyzed metallic alkoxide which substantially comprises  titanium  alkoxide  is applied over the silver layer.   Thereafter  the  applied  second  layer  is  heat treated to convert same to titania, with the heat treating temperatures  and  atmospheres  controlled  so  as  not  to affect the applied silver layer.  The two layer coating is applied by omitting the first TiO2 coating step.

Abstract: GREASE FITTING       ABSTRACT            An improved grease fitting is provided particu-larly suitable in high pressure applications where a polyester plasticizer is intermingled with a lubricant. In one embodi-nent of the invention, a metal ball is biased by a cylin-drical helical spring for sealing engagement with a plastic seat. A leg of the spring passes through the axis of the fitting, so that when grease is forced through the fitting, the unseated ball moves radially to allow the plasticizer and lubricant to pass through the fitting with less resis-tance. The helical spring is eniose in a sleeve, and a ?? or the sleeve enables the end of the sleeve to compress the plastic seat to a predetermined extent, thus prolonging the expected life of the plastic seat.

Abstract: ABSTRACT   A conveying mechanism and flexible carrier for transporting a planar printing plate and flexible overlying mask from a flat loading station to a precisely-curved cylindrically-shaped scanning station, and back to the flat loading station, is disclosed.  The vacuum carrier used is rigid in one axis and flexible in a second axis, and has a pair of reference strips which define a neutral bending axis for the plate and mask when the latter are wrapped around a pair of precisely machined cylindrical discs. By locating the flexible mask and printing plate outside the neutral axis of bending, both are placed in tension when wrapped around the discs.  This maintains  uniform contact between the plate and mask and prevents wrinkling of the mask as it overlies the plate. The carrier and discs support the plate and mask within a precise and uniform cylindrical plane for scanning with focused beams of radiation.  The transport mechanism applies a vacuum to the carrier while in its flat position and maintains the vacuum while wrapping the carrier around the spaced cylindrical reference discs.  When the image scanning is completed, the transport mechanism returns the carrier to its flat state for unloading of the printing plate and mask.

Abstract: Abstract of the Disclosure A method of improving the utilization of the heat energy produced in a wood grinding process when wood is ground in a grinding space (3) under a pressure exceeding atmospheric pressure, and warm shower water (G) is sprayed into the grinding space. Steam (H) is separated from the groundwood pulp (A) discharged from the grinding space in a steam separator wherein the groundwood pulp is allowed to expand from its inlet pressure to atmospheric pressure in at least two steam separators (11,14) by releasing steam from the groundwood pulp in each steam separator by decreas-ing the pulp pressure. The amount of steam (H1,H2) released in the separate steam separators is adjusted according to the proportions in which steam is needed for utilizations purposes. Thus the heat energy of the pressure grinding process can be recovered in separate steam fractions the amount and pressure of which correspond to the requirements of the utilization purposes. It is preferable to heat the shower water by steam of such a volume and pressure that the temperature of the shower water increases to a desired degree, preferably above 100°C. (Fig. 1).
