Abstract: ABSTRACT   An air hammer having a main body including an elongated cavity with a ram slidably mounted therein.  The ram is driven by compressed air delivered through inlet means to the cavity in such a way as to drive the ram up and down to impact a tool.  A shut off system is also provided to stop the hammer when it is unloaded.  The shut off system includes a passageway which directs air to hold the anvil away from the ram.  A further passageway through the anvil communicates the cavity beneath the ram with the upper end of the tool. When the tool does not engage work it uncovers an exhaust passage in the tool holder through which air can escape.

Abstract: 914,070 Abstract of the Disclosure A circuit is disclosed for serially formatting digital information such as may be provided in a digital audio magnetic tape recorder in a succession of data blocks or frames, each containing the same number of digital bits and in which each frame is delineated by a uniquely occurring digital frame synchronizing signal.  The digital information is formatted in a Miller or 3F code in which allowable tran-sitions between successive "1"s and "0"s result in pulses which are 1, 1-1/2 or 2 times the duration of a bit cell, hence giving rise to three characteristic frequencies and the term 3F code.  The frame synchronizing signal is generated by providing a signal comprising digital bits 1-0-0-1, which signal in a 3F code is characterized by a transition between the adjacent "0"s, and by appropriately inhibiting that tran-sition, thus creating a pulse which is three times the duration of a unit cell, hence giving rise to a new fourth frequency which cannot be normally created by any succession of "1"s or "0"s.

Abstract: TREATING MULTILAYER PRINTED           WIRING BOARDS        Abstract of the Disclosure Multilayer printed wiring boards are conventionally laminated using epoxy adhesives.  When the boards are drilled, a residual smear often remains within the drilled holes.  This smear prevents proper through plating of the holes and the layers are left without some of the intended interconnections.  In the past, the residual smear was removed by wet etching.  A technique is described using plasma etching with the conductive surface layers of the drilled boards as the electrodes to generate the plasma.  The plasma forms directly within the holes and effectively removes the smear.  A dielectric material in contact or close proximity to the perimeter of each board provides uniformity of treatment over the panels.

Abstract: Abstract of the Disclosure A plastic coating for plated metal shelving used in walk-in coolers, and the method of applying the coating to the metal shelving.  When the metal shelving is cleaned and prepared for the plating, a nickel film and a chromium film are electrodeposited in that order on the metal shelv-ing in two successive operations.  The deposited chromium metal surface is then treated with an iron phosphate in order to enhance the adhesion of a final outer layer of plastic.  The iron phosphate treatment is carried out in a three-stage spray washer operation.  The coating in the form of an epoxy resin is then applied, where the epoxy resin is preferably a thermosetting plastic of the Bisphenol-A type which requires specific time and temperatures to achieve a proper desired cure and color.

Abstract: Self Aligned Method For Making Bipolar Transistor Having Minimum Base to Emitter Contact Spacing Abstract A method for making a high performance bipolar transistor characterized by self-aligned emitter and base regions and minimized base and emitter contact spacing.  The disclosed method comprises forming a recessed oxide-isolated structure having opposite Conductivity epitaxial layer and substrate.  Multiple layered mesas of alternating silicon nitride and silicon dioxide layers are placed over the base region and over the collector reach-through region. Polycrystalline silicon is deposited between the mesas.  The mesas are undercut-etched to expose the extrinsic base region which is ion implanted.  Then, the mesas are removed to expose the emitter and intrinsic base regions as well as the collector reach-through regions.  The latter exposed regions are ion implanted appropriately.  Contacts are made directly to the emitter and collector reach-through regions and indirectly via the polysilicon to the base region.

Abstract: ABSTRACT         The invention is concerned with a method of recovering heat from smoke gases in a combustion plant, comprising the steps of compressing air for combustion to a first intermediate pressure in a first compressor, then compressing the air to a second higher pressure in a second compressor, passing the air at the second higher pressure to a combustion chamber,  and burning a com-bustible fuel in the presence of the air at the second higher pressure in the combustion chamber to produce smoke gases at substantially the second higher pressure. The smoke gases at the second higher pressure are passed through a first turbine to drive the turbine and reduce the pressure of the smoke gases to a second intermediate pressure, the first turbine being connected to the second compressor for driving the same.  Thereafter, water vapor in the smoke gases at the second inter-mediate pressure condensed to regain the heat of vaporization of the water vapor in the smoke gases, and then the smoke gases are passed through a second turbine to drive the turbine and reduce the pressure of the smoke gases to atmospheric pressure, the second turbine being connected to the first compressor for driving the same.  The method of the invention can be carried out in a combustion plant comprising first and second compressors connected in series to raise the pressure of combustion air from  atmospheric pressure to a first intermediate pressure and thence to a second higher pressure, and at least one combustion chamber operatively connected to the second compressor for burning fuel in the presence of the combustion air for producing compressed smoke gases at substantially the second higher pressure.  A first turbine is operatively connected to the combustion cham-ber and the second compressor for receiving the com-pressed smoke gases and reducing the pressure thereof to a second intermediate pressure thereby converting the pressure of the smoke gases to mechanical energy driving the second compressor means.  A condenser is connected to the first turbine for receiving the expanded smoke gases therefrom and recapturing the heat of evaporation from the water vapor in the gases. A second turbine is operatively connected to the condenser and the first compressor for receiving the expanded smoke gases from the condenser and reducing the pressure thereof to atmospheric while converting the pressure of the smoke gases to mechanical energy driving the first compressor.

This is effected by providing the carriage with a first scanner (preferably opto-electronic) arranged to scan marks on a synchronising scale when the carriage is moved along a scanning line,  the signals from the scanner being arranged to control a drive motor for the carriage.          Similarly, a second scanner is arranged on a carriage guide on which the carriage runs and which is itself movable in a direction normal to the scanning lines so as to scan marks on a second synchronising scale, the signals from this scanner serving to control a motor for the stepwise driving of the carriage guide.
