Abstract: Abstract of the Disclosure Apparatus for developing exposed diazotype sheet material in which an accurately metered amount of liquid developer is applied to the sheet material by an applicator roller.  The roller surface is essentially smooth and liquid developer is applied to the rol-ler surface in an amount metered by a metering blade assembly which includes a flexible support member carrying a resilient backing layer which, in turn, carries a fine mesh screen held in contact with the smooth surface of the roller.  A sheet of smooth, essen-tially continuous material is interposed between the screen and the roller surface when the apparatus is not in use and is retracted to enable direct contact between the screen and the roller surface when the apparatus is in use.

Abstract: ABSTRACT      An induction machine is driven to operate as a generator, and has its electrical output conductors coupled to a switching system, which can be an inverter circuit.  An oscillator and logic circuit are connected to regulate the switching of the power switches, such as thyristors, in the inverter circuit which operates as a switching system.  The thyristors in the switching system are regulated to switch at a frequency sufficiently below the synchronous frequency of the induction machine to enable the machine to build up and operate as a generator.  A modulator is connected to the oscillator to vary the oscillator frequency, and thus change the switching frequency of the switching system, above and below a reference level to provide a corresponding a-c output voltage, with a d-c average level, on the d-c bus conductors of the inverter circuit which operates as the switching system.  The amplitude and frequency of the a-c output voltage are controllable over a wide range of variations in both the shaft speed of the induction machine and/or the electrical load.  The system is also capable of producing an a-c voltage and a separate d-c voltage, and  both the a-c and d-c voltages can be separately controlled.

Abstract: A RESINOUS LINEAR BLOCK COPOLYMER OF A MONOVINYL-SUBSTITUTED AROMATIC COMPOUND AND A CONJUGATED DIENE Abstract of the Disclosure A resinous linear block copolymer of a monovinyl-substituted aromatic compound and a conjugated diene wherein the polymerized monovinyl-substituted aromatic compound blocks have a heterogeneity index within the range of about 2.3 to 4.5. The heterogeneity index is the ratio of weight average to number average molecular weight. Such compositions exhibit high impact strength and can be made either by bending two linear block copolymers made under different conditions so as to give different lengths of the polymerized monovinyl-substi-tuted aromatic compound blocks, or by adding the monovinyl-substituted aromatic compound and a polymerization initiator in two or more increments prior to adding the conjugated diene. These compositions are particularly useful in applications such as injection molded articles where high impact strength is desirable.

Abstract: ABSTRACT OF THE DISCLOSURE          A pin wheel feeding device includes a housing capable of being rotated about an axis, the housing having a peripheral wall containing a plurality of openings formed therein, each opening lying along a radial line extending from the axis of rotation of the housing.  A plurality of substantially identical pins are disposed within the housing in respective alignment with the plurality of openings, each pin capable of being moved along the respective radial line from a first position in which it is substantially entirely located within the housing to a second position in which it projects outwardly of the housing from the respective aligned opening.  Each pin includes a pair of opposing guide members, the point on each guide member located closest the opposing guide member lying substantially along the respective radial line.  A cam member disposed within the housing is capable of being fixed in position relative to the housing.  The cam member has a track formed thereon with which each of the pins is engaged with the pair of guide members thereof being located on either side of the track.  The pins follow the path of the track during rotation of the housing relative to the cam member.  The track has a first segment capable of maintaining a pin engaged therewith at its first position, a second segment capable of maintaining a pin engaged therewith at its second position, and a third segment intermediate and contiguous with the first and second segments for enabling a pin engaged therewith to move between its first and second positions during rotation of the housing.  The width of the track at the first, second and third segments is substantially coextensive with the locus of points traced by the closest adjacent points on the pair of guide members of each pin during movement of the pins along the first, second and third segments of the track.
