Abstract: ABSTRACT OF THE DISCLOSURE To enhance copy quality in an electrostatic type copier or reproduction machine, the photoconductive surface bearing the latent electrostatic image of the original being copied is, before development, exposed to a second charge generating device producing a relatively low charge opposite in polarity to the original charge.  The aforesaid second charge is desirably equal to or less than the image background voltage, and serves to reduce overall image charge and thereby neutralize to a large extent the image background voltage without changing or upsetting the image voltage contrast.  A low emission scorotron positioned between imaging and develop-ing stations may serve as the second charge generating device.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is provided for rendering a building material hydrophobic.  It includes the steps of first, applying to the surface of the building material a solution of a hydrophobic agent, admixed with a filler having a surface area of at least 50 m2/g, and then removing any residue of filler from such surface after evaporation of the solvent. This hydrophobic solution simultaneously cleans the sur-face of the building material, thus rendering any previous cleaning step superfluous and saving the expense of such a step.  A greater penetration depth is also achieved which saves the expense of repeated application of the hydrophobic solution.  Furthermore the solutions are not so mobile as the previously used solutions so that it is easier to avoid the solution running onto areas where it is not intended to be applied.

Abstract: PLASMA COLLECTION SYSTEM                    AND BOTTLE THEREFOR              Dennis F. Shine & Gunther W. Torau Abstract of the Disclosure There is disclosed herein a method for collecting blood plasma in plastic bottles wherein the blood plasma can be stored for periods of time and can then be utilized in obtaining blood fractions therefrom.  The method includes the concept of filling a previously sterilized and hermetically sealed bottle with blood plasma. The bottle, after filling, is sealed at the neck portion thereof by means of heat sealing. The portion of the bottle above the heat seal is severed. Thereafter, the filled bottle is frozen and transported to the site for use. The bottle containing the plasma is then thawed and conveyed to a plasma removing device. The plasma is removed by severing a portion of the bottom of the plastic bottle, thereby permitting the liquefied plasma to flow therefrom into a collection vat. The bottle in which the plasma is collected and stored has a unique configuration in that it is a blow-molded bottle having a cap thereon which is produced integrally with the bottle so that it is always in a sterile condition. In one embodiment, the cap is broken from the top of the bottle, thereby exposing a mouth having a threaded config-uration thereabout so that a cap may be screwed thereon. The cap has means for venting and for introduction of a probe through which the plasma is conveyed into the bottle. In another embodiment, the top of the bottle terminates in a membrane suitable for piercing with a probe and a venting arrangement is included, whereby the plasma can be charged into the plastic bottle. Below the mouth, there is a flattened neck portion providing an area at which a heat sealing means can be applied to further compress into abutment the neck and to heat seal same in that condition. The upper portion of the mouth carrying member can be severed from the bottle.

Abstract: ABSTRACT     It is important that a data transmission system should be fast, utilize a minimum of band width and be accurate in the presence of high noise levels.  The invention provides a frequency shift keying data transmission system for transmission of binary coded information in which the mark of the coded pulse waveform is represented by a half cycle of one keying frequency and the space is represented by a half cycle of another keying frequency.          An improvement in speed, band width utilisation and accuracy at high noise levels is obtained by providing that the transmission signal is an approximately sinusoidal waveform of which the phase is continuous at the transitions, the time lengths of the mark and space symbols thereof are matched to the half time periods of the respective keying frequencies and the slope is constant at the cross-over points.

Abstract: METHOD AND APPARATUS FOR PURIFYING AQUEOUS STREAMS CONTAMINATED WITH ORGANIC MATERIALS.                  The Abstract of the Disclosure Aqueous streams contaminated with minor amounts of orga-nic materials are separated into an aqueous fraction which is concentrated with respect to the organic contaminants and a water fraction relatively free of the organic contaminants by a method which includes a unique combination of reverse osmosis (RO) and ultrafiltration (UF).  The organic contaminants include substances having molecular weights of less than 10,000 which are soluble in the aqueous stream initially but have limited solubility ranges and are precipitated therefrom upon concentration.  The contami-nated aqueous stream is circulated from the high pressure compart-ment of a RO unit to the high pressure compartment of an UF unit, then to the low pressure compartment of the UF unit, and then back to the high pressure compartment of the RO unit.  The conta-minants are concentrated in the high pressure compartment of the RO unit, and a portion thereof is precipated or otherwise rendered amenable to removal along with the UF concentrate upon passing the RO concentrate from the high pressure compartment of the RO unit to the high pressure compartment of the UF unit.  Soluble organic contaminants remaining in the aqueous stream are removed in the UF permeate and are recycled back to the high pressure compartment of the RO unit for further concentration and precipitation, follo-wed by recycling to the high pressure compartment of the UF unit for removal.  The above steps are preferably practiced on a conti-nuous basis, thereby producing a substantially pure water RO per-meate and an aqueous UF concentrate of the organic contaminants on a continuous basis.  The RO permeate may be recycled in indus-trial processes or otherwise used as fresh water.  The UF concen-trate may be further processed to recover the organic contaminants for use in industrial processes or for sale as a marketable product, or it may be used as boiler fuel without further processing.      The invention also provides improved apparatus which is especially useful in practicing the method of the invention.  The method and apparatus of the invention are very effective in treating waste industrial streams which contain small amounts of organic materials such as polyols and organic polymers in general.
