Abstract: A magnetic brush developing system for electrostatic duplication using a monocomponent developer controls the thickness of the developer on the brush such that the necessary amount of developer is applied to the photosensitive surface which carries the latent electrostatic image. A capacitive sensor in the form of a rigid plate of conductive material is spaced closely adjacent to the surface of the roll on which the magnetic brush is formed. The dielectric constant depends on the thickness of the developer in the magnetic brush and is detected by the capacitive sensor. The capacitance of the sensor is converted, into a pulse train the duty cycle of which is modulated in accordance with the change in capacitance, by a circuit arranged on a circuit board in close proximity to the sensor to provide a compact structure which is not subject to perturbation which could effect the capacitance presented by the sensor. The circuit controls the supply of developer to the brush in response to the duty cycle of the pulse train by causing the dispensing of the developer when a duty cycle change corresponding to the decrease in the thickness of the developer in the brush occurs and terminating the dispensing of the developer when the thickness becomes excessive thereby providing a layer of developer of consistent thickness in the brush so that copies of desirable optical density are obtained.

Abstract: A method of forming a pinchuck is described using lithographic techniques to define and to etch a pattern of pins from an extremely flat surface. A block of suitable material is polished to form such an extremely flat surface. The desired pin pattern (preferably along with a vacuum sealing ring surrounding the pins) is defined with a mask, which is then used to etch the flat surface so as to form an array of pins (and optional sealing ring). Since the pins (and the optional vacuum sealing ring) are formed from a surface which is already flat, it is not necessary to polish the pins after they are formed. The top surfaces of the pins (and the top surface of the optional vacuum sealing ring) already lie within a common plane. Since lithographic techniques are used, the pin head dimensions, the number of pins, the arrangement of pins, and the density of pins all may be freely chosen without affecting the fabrication cost. 
     The drawings shows the completed pinchuck in use as a vacuum pinchuck supporting a silicon wafer 36. The pinchuck comprises a block of silicon having two holes 14,15 in it through which vacuum suction and an electrical connection 38 can be made to a wafer 36 mounted on the chuck. The chuck comprises the pins 30 and the annual sealing ring or flange 32. The surface layer 34 of the block is oxydised while the base is not to allow electrical contact to be made therewith.

Abstract: The invention provides an aluminum based alloy consisting essentially of the formula Al bal Fe a X b , wherein X is at least one element selected from the group consisting of Zn, Co, Ni, Cr, Mo, V, Zr, Ti, Y, Si and Ce, "a" ranges from about 7-15 wt %, "b" ranges from about 1.5-10 wt % and the balance is aluminum. The alloy has a predominately microeutectic microstructure. 
     The invention also provides a method and apparatus for forming rapidly solidified metal, such as the metal alloys of the invention, within an ambient atmosphere. Generally stated, the apparatus includes a moving casting surface which has a quenching region for solidifying molten metal thereon. A reservoir holds molten metal and has orifice means for depositing a stream of molten metal onto the casting surface quenching region. A heat mechanism heats the molten metal contained within the reservoir, and a gas source provides a non-reactive gas atmosphere at the quenching region to minimize oxidation of the deposited metal. A conditioning mechanism disrupts a moving gas boundary layer carried along by the moving casting surface to minimize disturbances of the molten metal stream that would inhibit quenching of the molten metal on the casting surface at a quench rate of at least about 10'Cisec. Particles composed of the alloys of the invention can be heated in a vacuum and compacted to form a consolidated metal article have high strength and good ductility at both room temperature and at elevated temperatures of about 350°C. The consolidated article is composed of an aluminum solid solution phase containing a substantially uniform distribution of dispersed intermetallic phase precipitates therein. These precipitates are fine intermetallics measuring less than about 100 nm in all dimensions thereof.

Abstract: With such a circuit arrangement, the sampling clock is synchronized to the frame position and the phase of the characters of a received character stream containing a "unique word" at regular intervals. In a digital correlator (1), a crosscorrelation function is generated from a unique word stored therein and from the received, sampled character stream, and a frane detection circuit (2) derives a frame clock (RT1) from those maxima of the crosscorrelation function recurring at intervals of one frame period. To achieve synchronization at any polarity of the received character stream (i.e., even if the tip and ring wires of the subscriber line are interchanged), a second frame detection circuit (3) derives a second frame clock (RT2) from those minima of the crosscorrelation function recurring at intervals of one frame period. A clock selection circuit (8) determines which of the two frame clocks is received within a limited time interval. From this frame clock, control information for representing the phase of the sampling clock (AT) is derived in a phase synchronization circuit (10).

Abstract: A power assisted respirator comprises a facepiece (1) for covering at least the nose and mouth of the wearer which has an outlet provided with a one-way exhale valve (2) which is openable to permit air to flow out of the facepiece when a predetermined pressure P is established within the facepiece. A pump unit (5) supplies air to the space within the facepiece. The pump unit (5) may be connected to an inlet of the facepiece by a flexible hose (4) or may be mounted directly on or in the facepiece. A filter canister (11) is connected to the inlet (10) of the pump means for filtering air supplied to the facepiece. A one-way inlet valve (13 or 16) is provided in the path of air flowing from the pump unit to the facepiece and a pressure sensor (12) is provided for sensing the pressure of air in the region of the pump unit inlet for causing deenergisation of the pump unit when the pressure in the region of the pump unit inlet exceeds a predetermined level. The operating parameters of the pump of the pump unit and the exhale valve are selected so that the pressure within the facepiece at which the exhale valve will open slightly exceeds the pressure at the outlet of the pump which will cause the pump to cease or substantially cease operating effectively. Thus in use, during exhalation the pressure within the facepiece will rise to a level at which the inlet valve (13 or 16) will close causing a buildup of pressure at the pump outlet which will cause the pump to cease operating effectively. Meantime the exhale valve will open. During normal operation of the pump, because of the resistanceto flow provided by the filter canister, the pressure in the region of the pump inlet will be sub-atmospheric. The pressure sensor (12) is arranged to sense a rise in this pressure resulting from the pump ceasing or substantially ceasing to operate effectively and will cause deenergisation of the pump. The reduction in pressure within the facepiece at the start of inhalation, which is communicated to the pump, is sensed by the pressure sensor (12) which then causes reenergisation of the pump.
