Abstract: METHOD OF MODIFYING THE DEVELOPMENT                    PROFILE OF PHOTORESISTS                   Abstract of the Disclosure The cross-sectional profile which is produced upon development of a layer of alkali soluble resin-diazo ketone photoresist is modified by treating the layer with a solvent or solvent mixture which is different from but miscible with the solvent or solvent mixture used to form the resist layer.  The treating solvent is believed to dilute the resist solvent in a surface layer portion of the resist thereby modifying the alkaline developer solubility of this portion. Undercut resist profiles may be obtained by this method with normal optical exposure of the resist.

Abstract: HAND OPERATED LABEL PRINTING MACHINE            ABSTRACT OF THE DISCLOSURE           A hand operated label printing machine in which a series of labels are incrementally fed onto a printing platen in response to the squeezing of a hand lever so that they may be imprinted with selected indicia.  The hand labeler is equipped with a constant pressure printing mechanism interposed between the hand lever and the frame of the hand labeler.  That mechanism is comprised of a pressure applying assembly in the form of a biased cam pivotally mounted to the hand lever and a pressure receiving assembly also in the form of a biased cam pivotally mounted to the machine frame.  The former assembly is brought into abutment contact with the latter assembly at their cam surfaces, while the hand lever is being squeezed and the cams are then hindered from pivoting following abutment.  The label printing force is the force that has to be applied for the former assembly to ride over the latter assembly which occurs when one of the assemblies resiliently deforms.  The hand labeler also has an ink supply device, comprising a holder that holds two inking rollers.  The ink supply device is movable to bring the inking rollers into and out of contact with the types of the printing device to ink them.  The ink supply device is actuated by a mechanism which is comprised of a combination of a cam pivotally attached to the machine frame and a roller pivotable with the printing head supporting printing lever for being received in the cam and for pivoting the cam with the printing lever.  A link joins the cam with the holder, so that pivoting of the cam moves the holder.  Guide grooves in the machine frame  regulate the inking roller motion along different loci.  The link has a slot in it which prevents the holder from linear protrusion to the front of the labeler frame.

Abstract: ELECTROGRAPHIC PROCESS FOR    MAKING TRANSPARENCIES   Abstract of the Disclosure A transparency that is used to project an image onto a viewing surface such as a screen is prepared by an electrographic copying process.  An element used in this process comprises a trans-parent support that is coated with an image-receiving hydrophilic colloid layer that receives an image pattern of fusible toner particles.  The image pattern of toner particles is fused to the hydro-philic colloid layer by contacting the toned image-bearing layer with a heated fuser surface such as a fuser roll.  The fuser surface is coated with a release liquid which inhibits offsetting of the toner particles onto the fuser surface.          Transparencies prepared by this process exhibit  good resistance to abrasion in toned areas while also displaying substantially no release liquid in non-toned areas upon projection viewing. Furthermore, toned areas of such transparencies can be selectively removed by light rubbing with a moist cloth or tissue.

Abstract: ABSTRACT OF THE DISCLOSURE Sheet metal is processed by providing one or more corrugations longitudinally along the sheet in a position spaced from both lateral edges of the sheet while the lateral edges are maintained in fixed relationship to each other, thereby causing the sheet metal portion containing the corrugations to be stretched.  The corrugated portion is subsequently rolled or otherwise pressed to flatten out the corrugations either partially or completely, resulting in a sheet which is wider than the original, but which still has certain areas having the original thickness.  She sheet metal thus processed may be utilized to form structural members such as channels or studs which are less expensive for a given size than conventional structural members, but which still exhibit sufficient supportive strength by virtue of the portions thereof Which retain their original thickness.

Abstract: APPARATUS FOR STERILIZING LIQUIDS            ABSTRACT OF THE DISCLOSURE          The invention relates to an apparatus for sterilizing liquids by means of ultraviolet rays, using as the radiation source a low pressure, high current, mercury vapour lamp (UV lamp) which is provided with an appendix-shaped piece of tube (appendix) located on the discharge tube.  In order to be able to regulate the temperature of the appendix in a defined manner even while the lamp is in operation and in order to achieve longer life of the UV lamp, an airstream circulating through the apparatus is used to cool the UV lamp.  This airstream follows a path such that the air warmed on the discharge tube travels past the electrode bulbs of the UV lamp to the outer wall of the pipeline, through which pipeline the liquid to be sterilized flows.  The air which has cooled on the outer wall of the pipeline is then returned to the UV lamp and must be at a temperature which is lower than the operating temperature of the appendix, so that the temperature of the latter can be regulated in a defined manner by means of a heater.

Abstract: FLOW DEVICE AND METHOD          Abstract of the Disclosure A flow device and method delivers a gaseous medium to utilization equipment having variable pressure condi-tions at its intake.  A gaseous medium intake zone con-nects with structure defining a variable area throat zone for constricting the flow of the gaseous medium to increase its velocity to sonic.  The throat zone is adjustably varied in correlation with operating demands imposed upon the utilization equipment.  Wall structure downstream from the throat zone provides a gradually diverging zone for efficiently recovering the kinetic energy of the high velocity gaseous medium as static pressure.  Through such efficient recovery the velocity of gaseous medium through the throat zone is sonic over a wide range of pressure conditions at the intake of the utilization equipment. Perforations are provided in the wall structure downstream and spaced from the throat zone, and these perforations connect on the back side of the wall structure with the intake of the utilization equipment. When supersonic flow occurs the high velocity mass moving past the perforations pulls a small portion of the gaseous medium already delivered to the intake of the utilization equipment into the gradually diverging zone.  Such recirculated medium functions to disturb the supersonic flow and thereby shift the location of shock upstream from where it would other-wise occur to the location of the perforations.  While shock causes the flow to separate from the wall structure, upstream shifting of the shock leaves sufficient wall structure downstream to allow the flow to reattach before delivery to the intake of the utilization equipment.  Such reattachment eliminates flow jetting.

Abstract: Docket K4084 EAO:1hw IMPROVED AM STEREO TRANSMITTER             ABSTRACT OF THE DISCLOSURE       A transmitter for an independent sideband (ISB) AN stereo system is provided with a phase modulator which includes means for generating second order upper and lower sidebands which are proportional to the stereo difference signal.  No second order upper and lower sidebands are generated when the L and R audio signals are equal.  The phase modulator uses an ISB suppressed carrier signal generator and a quadrature demodulator which demodulates the quadrature component of the output of the ISB generator.  This demodulated component is used in a balanced modulator to modulate the ISB signal and thereby generate a signal having a carrier and upper and lower first and second order sidebands.  This signal is combined with a carrier signal of selected amplitude and the ISB suppressed carrier signal to provide an output signal which, after limiting, is a phase-modulated signal having first and second order upper and lower sidebands.  When the L and R signals are equal, all of the sidebands of this signal vanish.  The phase modulated signal is amplitude modulated using an audio signal corresponding to the summation of the L and R stereo signals.
