Abstract: Abstract of the Disclosure A hydrogen-containing amorphous silicon layer is formed on a substrate held below 200°C, in a plasma atmosphere.  The plasma is then stopped and the layer is heated in a temperature range of 200°C - 400°C without intermediate cooling.  In this way the saturation field for photocurrent of electrons or holes can be made lower than heretofor.  When using electrons as the major carriers, the heat-treating temperature is set preferably in the temperature range of 200°C - 240°C, and when using holes as the major carriers, it is preferably set in the range of 270°C - 400°C.

Abstract: ABSTRACT OF THE DISCLOSURE           A compliant pile system for supporting the vertical weight of a guyed tower structure installed in a body of water.  The pile system is comprised of at least one pile element which in turn is comprised of a pile jacket and a pile member.  The pile jacket extends from one point in the structure to a second point which lies above the first point and is attached at only one point to the structure.  The pile member passes through the pile jacket and is forced into the marine bottom and is attached only at its upper end to the pile jacket.  In one modification, the pile jacket is comprised of an odd number of concentrically positioned sleeves with the pile member being affixed to the top of the innermost sleeve and the outermost sleeve being affixed only at its bottom to the structure.  The sleeves, if more than one, are attached to each other at their respective alternate ends.  In another modification, the pile jacket is comprised of an even number of concentrically positioned sleeves with the pile member being affixed only at its upper end to the innermost sleeve and the outermost sleeve being affixed only at its upper end to the structure.  The sleeves themselves are connected together only at alternating respective ends thereof.  By constructing and affixing the pile jacket as described and affixing the pile member thereto only at its upper end, the effective length of the pile element is increased and its axial stiffness is reduced.

Abstract: ABSTRACT OF THE DISCLOSURE    A device for transformation of alternating current-voltage which includes a core, a primary winding subassembly and a secondary winding subassembly.  One or both of the primary and secondary winding subassemblies consists of at least one pair of equal turn and approximately equal resistance windings wrapped co-directionally around the core, and each having an equal number of tapped sections. A special tandem switch selectively interconnects tapped sections within winding pairs to provide a desired output terminal winding array such that all sections connected through the switch are energized, and are in the current carrying path at all selected switch positions, with selectively seriesed and selectively paralleled portions of the switch-coupled winding pairs being selectively encircuited at each switch position.  The functioning primary and secondary windings are asymmetrically disposed in relation to each other at most of the switch positions, and the leakage reactance is unequal through the several paired windings when they are connected by said transformer switch to place less than all of the tapped sections of each in parallel.

Abstract: ABSTRACT         A latching mechanism is described which senses when a bale is ready for discharge from the bale forming chamber. As implemented, the enclosure for the baling chamber was hinged along the front edge to allow the upper portion to open like a rearward facing clam shell for discharge of a completed bale through a tailgate.  The latching mechanism holds the opposing tailgate faces of the enclosure together while the bale forming process is being completed.  The latching mechan-ism senses bale density while allowing only a slight opening of the tailgate in response to application of large compres-sive forces within the baling chamber.  The profile of the slot in each latch is uniquely cut so that the forces tending to force open the tailgate can be matched to a spring.  The spring is adjustable so as to allow the latch assembly to begin rotation toward the released condition as the bale density reaches a pre-established level.  A change in the profile of the latch slot allows it to be displaced enough to sense bale density without allowing it to completely unlatch before the operator desires.

Abstract: ABSTRACT OF THE DISCLOSURE         Display apparatus includes  a microcomputer,  a multi-digit seven-segment display module,  and a decoding addressable  latch  device.   The  segment  inputs  of  the display module are connected through a buffer to microcosm-puter output lines to permit the microcomputer to generate seven-segment  code.   The  address  inputs  of  the  latch device  are  connected to  the  same  microcomputer  output lines,  and the output lines of the latch are connected through  a buffer to digit  select  line  of the display device.  The microcomputer first generates a digit select address code which is supplied to the latch inputs and frozen  there  by  microcomputer  actuation  of  the  latch ENABLE input.  This causes the latch to latchably energize the  specified digit  select line,  and the microcomputer outputs  the seven-segment  code  of  the  desired  display character to the segment inputs of the display module.  By connecting the latch address inputs  and display module segment inputs in parallel, the apparatus provides micro computer generation of the seven-segment code while reduc-ing the number of microcomputer output lines required.          Objectionable effects of "ghost" energization of undesired segments caused by multiplexing latch address information and display data are minimized by selection of the multiplexed segments according to predetermined cri-teria, and by deenergizing all segments of all digits when blank character is to be displayed.

Abstract: Abstract Pipeline Monitoring Apparatus An apparatus is described for providing a visual display of the presence or absence of a change from the normal to the abnormal in the condition of a pipeline, for example an adverse change in the current supply to the pipeline for cathodic corrosion control purposes. In a preferred form, the apparatus consists of a transparent weather-proof housing within which is mounted two sets of vanes, one set being immovable and the other set being mounted on a rotatable central shaft which is linked to the instrument monitoring the condition of the pipeline.   The vanes are painted in distinctive colours so that in the normal position, a single colour or distinctive pattern can be seen by a distant observer as an indication that all is well.   Upon an adverse change in condition, the central shaft is rotated so as to move the movable vanes to another position where a different colour or colour pattern is displayed, thus indicating the occurrence of the adverse change to the distant observer.

Abstract: ABSTRACT OF THE DISCLOSURE        An orthodontic bracket of the type intended for cementing directly to a previously etched surface of the tooth enamel is made by applying to the lingual face thereof that contacts the tooth enamel surface a thin porous layer of sintered metal powder which is arranged to have a porosity such that it has keying characteristics close to that of the etched enamel and thereby facilitates the cementing adhesion of the bracket to the tooth.  A particularly suitable metal powder consists of particles of the same alloy as the bracket metal and of size in the range about 10 to about 150 microns (-100 mesh), preferably from about 10 to about 50 microns (-300 mesh) applied in a thickness of about 0.05 to 0.2 mm, by means of a sintering operation that fuses the particles to the lingual face and to one another.  The porous layer preferably is pre-filled with a polymer material compatible with the bonding cement, such as the sealant employed with the cement, so as to protect the layer against mechanical damage caused by bending of the bracket by the orthodontist to conform the bracket surface more closely to the tooth surface to which it is to be applied.
