Abstract: A B S T R A C T  O F  T H E  D I S C L O S U R E       "TYPESETTING SYSTEM"           A typesetting system comprises a plurality of user terminals which are connectible with a remote central typesetting bureau through the public telephone system.          Each terminal has a display screen or VDU, an operating keybank and a facsimile printer.  The bureau comprises a photo-typesetting  installation  and  a  computer  proof generator.   On command by a connected user the proof generator is operative to transmit over the connecting telephone line signals which operate the facsimile printer at the user terminal to reproduce a hard copy of the type character image which has been set into a memory of the typesetter installation by the user.  This facsimile proof can be obtained before the typesetter actually sets the type.

Abstract: ABSTRACT OF THE DISCLOSURE                        WATER ENGINE   A water engine comprises a float arranged for reciprocal movement in a chamber under the action of a head of water.  The chamber is filled with water from an upper level by means of a valve and is emptied to a lower level by means of a further valve.  A cross-head is mounted atop the float and two pairs of hydraulic rams are pivotably connected to the cross-head.  The pains of rams are also pivotably connected to pairs of sliders which are adjustably mounted on stanchions.  When the float is caused to rise, hydraulic fluid in the upper pair of rams is pressurised because of the shortening of the rams, whilst hydraulic fluid is drawn into the lower pair of rams by extension thereof.  When the float is caused to fall, the opposite is true.  Each pair of rams pivots as the float moves, the arrangement being such that for whichever pair of rams is on its working stroke there is progressively less shortening of that pair of rams per unit travel of the float.

Abstract: Abstract of the Disclosure A method and apparatus for radiant heating of hollow thermo-plastic article preforms to the molecular orientation temperature, radiant energy is both converted to heat at the article surface and penetrates the interior of the article wall and is therein converted to heat.  The principle limitation of radiant heating is the capacity of the material to conduct heat away from the surface where extreme temperatures would result in crystallization of the material.  To achieve the desired temperature uniformly throughout the article wall, brief periods of intense infrared radiant heating are alternated with brief periods of negligible heating to take advantage of the combined effects of radiant and internal conductive heating.  The article preforms are rotatably supported parallel to a plane of quartz lamps so that the combined patterns of radiant emission of all the lamps are distributed in continguous segments over the preform surfaces.  The articles are rotated while the quartz lamps are alternately energized with high and low levels of power for presettable periods to produce alternate periods of intense infrared radiant emission and insignificant radiant emission.

Abstract: RCA 77,180 Abstract In a phase locked loop tuning system including a prescaler for dividing the frequency of the local oscillator signal by a factor selected to make the resultant frequency divided signal compatible with digital processing portions of the tuning system, a frequency selective network is coupled to the prescaler to tune the self-oscillation frequency of the prescaler to a frequency not corresponding to the local oscillator frequency of any legitimate channel. In this manner, when a new channel is selected and the amplitude of the local oscillator signal is below the threshold at which the prescaler will respond to it, the phase locked loop will properly control the local oscillator, rather than respond to a self-oscillation signal which may otherwise  correspond to the local oscillator frequency for the selected channel.

Abstract: ABSTRACT     DESALINATION DEVICE AND PROCESS     A membrane distillation module is provided with a  thin, flexible microporous membrane (16) positioned against an impermeable  condensor  sheet  (12) that is  stiffer  in bending than the membrane.   Distillate vapour  diffuses through  the  membrane from a hot feed  flowing  rapidly past  the membrane,  and condenses and collects between, and  in  intimate contact with,  the  membrane  and  the condensor  sheet.   The condensed distillate is stripped by  forces  exerted  by  the  hot  feed  acting  on  the distillate  across  the membrane,  and  flows  toward  a distillate   outlet  (40)  located  in  the   downstream direction  of the hot feed flow.   Cold feed flows  past the  condensor sheet in the counter direction to that of the   hot  feed  for  absorbing  the  latent   heat   of condensation,  and  is subsequently additionally  heated and  introduced  into the hot  feed  channel.   Expanded microporous   polytetrafluorethylene   (PTFE)   is   the preferred membrane material, and a spiral-wound assembly is the preferred configuration.
