Abstract: ABSTRACT:           The invention relates to a receiver circuit comprising a loop in which the oscillator frequency is controlled by the useful signal, the loop gain in the useful tuning range being negative and greater than unity.  An attenuator is provided which is controlled such by a control circuit that at larger deviations of the intermediate frequency operative in the loop from a target value the loop gain is reduced.  This improves the tuning behaviour.

Abstract: A filter for separating constituent components of fluids includes a plural-layer sheet-like member which is multiply pleated to provide layers of the same or different porosity or to provide structural support layers for pleating a soft or membrane-like filter layer. The multiple layers may be pre-joined or delivered from individual locations to a pneumatic conveyor passage of predetermined cross-section through which the adjacent layers are conveyed by a conveyor gas. The layers are crimped to form pleats by withdrawing the material at a lower linear speed than that at which it is supplied to the passage. Pleating is facilitated by venting the conveyor gas at a passage section of enlarged cross-section. The pleating material is subjected to a hot gas, such as steam, and then cooled by a cooling gas to effect bonding of the layers in the pleated state.

Abstract: ABSTRACT In a rotary hermetic compressor an improved lubrication arrangement is provided for the sliding cylinder vanes.  An oil pump in the lower portion of the crankshaft extends into the oil sump of the compressor.  The oil pump comprises an axial aperture in the crankshaft which angles diagonally radially outwardly in the upward direction.  Oil is pumped through this aperture into an annulus surrounding the crankshaft.  A passageway in the outboard bearing conducts the oil radially outwardly from the annulus and then upwardly against gravity to a vertical oil channel which is open to both sides of the sliding vane and adjacent thereto.  The positive pressure provided by the oil pump will ensure that the oil channel is filled with oil at all times.  Excess oil exits at the upper end of the vane through a relief in the main bearing and then flows down around the cylinder by gravity and into the oil sump.

Abstract: CYLINDRICAL BALER HAVING BALE-SHAPE-RESPONSIVE LOADING CONTROL SYSTEM            Abstract of the Invention As the tractor and baler are driven straight down the windrow, hay is picked up and placed upon a  platform  conveyor  which  transfers  the  same rearwardly toward the baling chamber, during which transfer a deflector diverts the crop stream into an appropriate one of three axial sections of the chamber  as  determined  by  sensing  and  control mechanism associated with the baler.  As the hay builds up in one of the sections, the sensors of the mechanism compare the size of that portion of the bale with the bale portion in the next adja-cent chamber section,  and once the differential between the two bale portions reaches a certain predetermined level, the control mechanism swings the deflector to its next position, directing hay into that next adjacent section to build up that portion of the bale.  While build up is occurring in that section, such build up is compared with that in the next adjacent section until the de-flector is shifted again,  and so on, until a finished bale of uniform diameter from end-to-end has been completed without requiring that the operator weave the baler back-and-forth on the windrow. The need for hay within the respective chamber sections  is sensed by the difference in tension  of  forming  belts  associated  with  the corresponding chamber  sections,  and  a micropro-cessor serves as the primary control source for the deflector movement.

Abstract: LIGHT PATTERN GENERATOR            ABSTRACT OF THE DISCLOSURE     A light pattern generator is utilized to produce an image which is projected onto a stage or screen. The image is derived from a beam of light.  The light pattern generator comprises a heat resistant glass plate having a reflective layer deposited on one surface thereof.  A nonreflective layer is deposited on the surface of the reflective layer.  Both of the layers are etched to produce an opening extending through the layers wherein the opening has the shape of the desired image.  The beam of light is directed through the transparent plate and the portions not passed through the operation are reflected by the mirror surface of the reflective layer.  This prevents the buildup of heat within the light pattern generator.  Any extraneous light which is received at the nonreflective layer is absorbed to prevent the escape of unwanted light and its projection to the stage.
