Abstract: ABSTRACT OF THE DISCLOSURE A pneumatic flat pad is provided herein.  It includes two opposed covers of flexible material which are spaced apart from each other and which are joined at their margins by a marginal joint so that the two covers and lateral marginal joint cooperate to form between them a hermetically sealed hollow space.  A plurality of cord  inserts æ e embedded within the covers, each of said covers being reinforced by at least one embedded cord insert. An attachment  is provided for connecting the hollow space to a source of compressed air.  At least one of the cord inserts of one of the covers is embedded within, and extends through the lateral marginal joint of the pad to the other cover is which it is also embedded and within which it over-laps a portion but less than all of that cord insert of the other cover. In this way, the lateral marginal interconnecting edges are reinforced so that the lifting cushion so provided is much stronger and safer in use.

Abstract: Abstract of the Disclosure A method of producing a conduit intended for communi-cation with a plurality of working-medium sources, which conduit includes at least two connecting elements spaced apart along the length of the conduit and secured thereto.  Each connecting element has a through passage communicating with the passage of the conduit and intended for connection with a source of a working-medium.  The axis of the through passage is parallel to the axes of through passages of other connecting members and communicates with the conduit.  To make such a conduit, a continuous-surface conduit is fed to a die-casting machine and is placed in its casting die, whose shape corresponds to that of connecting elements, in such a way that the axis of a core form-ing the through passage of each connecting element in the casting die is offset with respect to the conduit's axis with a distance therebetween being sufficient to obtain a strong and tight coupling of the connecting element with the conduit and provision of access for a working tool adapted to make a duct communicating the through passage with the conduit from the side of the former.  Thereafter, the connecting elements are formed by a known method, and the coupling of the conduit with the connecting elements is obtained by means of a pressing force arising on the external surface of the conduit during the period of crystallization of the connecting element's material.  A duct for communication of the through passage in the connecting ele-ment with the conduit passage is then made by a known method.          The conduits produced by the method being claimed are success-fully used in diesel engines.

Abstract: ABSTRACT OF THE DISCLOSURE Alignment plate construction for use in electrostati-cally aligning particles for particleboard production includes a plate of conductive material to which is secured flexible, con-trolled resistive material.  In a bank of successively positioned plates, particles which are permitted to pass downwardly between the plates are unidirectionally aligned, and the flexible mater-ial ensures that the electric field lines between the plates remain substantially horizontal over the entire plate and mater-ial height so that field line distortion does not occur adjacent a mat being formed beneath the plates.  Because the flexible material is of controlled resistance, voltage grading occurs across its height, arc over between the plates and a conductive caul plate is thereby prevented.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention provides a lid for a cooking pan having a central knob and two lid portions.  The lid portions can be adjusted between a spaced-apart condition and a juxtaposed or surface-contact position.          Each lid portion has apertures therethrough, but the apertures are not in alignment as viewed vertically.          Thus, when the lid members are separated there are provided vent passages for cooking fumes, etc. to escape from a pan or pot being covered by the lid.  Conversely, when the lid members are juxtaposed in surface-contact, the vent passages are closed, and escape of cooking fumes is restrained.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides a liquid nutrient composition for agricultural purposes incorporates urea, calcium chloride, and water, to 100% and a proportion of urea lying in the range 38%-60% CO(NH2) in which for any particular percentage x of urea lying in said range, the percentage of calcium chloride contained is defined by the equation:- Percentage CaCl2 - 42.27 - 0.455 x, the percentage x being treated as a simple numeral.  The composition is useful as an additive to animal feedstuffs so that the feedstuff will contain an adequate quantity of nitrogen while remaining palatable.  The composition has the operational advantage that it remains completely liquid while containing less water than known urea solutions thus reducing its bulk for a given quantity of urea.  It is already known to provide strong solutions of urea.  These contain more than 50%/50% urea/water but must be stored at an elevated temperature to avoid precipitation.  The presence of CaCl2 and urea in the proportions stated provide the inventive effect over the prior art.

Abstract: METHOD FOR EFFECTING SUSTAINED COMBUSTION OF CARBONACEOUS FUEL            Abstract of the Disclosure A method for effecting combustion of carbonaceous fuel is operative to sustain the combustion at a predetermined rate or rates of total fuel demand, the fuel being distributed between two combustion stages to make up the required total feed rate.  Thus one portion, usually about 20-70 percent, of the total fuel is fed to a thermal combustion stage.  Suf-ficient air is supplied simultaneously to the thermal combus-tion stage, preferably about 125 to 185 percent of the stoichio-metric amount of air, to effect substantially complete combus-tion of that portion of the fuel and produce a heated effluent.          An additional amount of relatively cool air is mixed with this effluent, and the resulting cooled mixture continues through the mixing zone, the additional air being sufficient to inhibit preburning of the remaining portion of the fuel which is added downstream in the mixing zone.  This cooled mixture in the mixing zone, upon and following the introduction of the addi-tional fuel, is at temperatures within the range of about 500°-1200°F.  The enriched fuel-air admixture then is combusted in the presence of a catalyst, the admixture providing combustion conditions in the catalyst stage giving a high rate of heat release without substantial formation of pollutants.

Abstract: ABSTRACT OF THE DISCLOSURE      A transistor switch short-circuits the main field rotor winding of a synchronous machine during start-up.  A transistor is connected across the main field rotor winding and is responsive to the polarity of the voltage induced in the main field rotor winding by the main stator winding.  When the voltage is of one polarity, the transistor conducts to short-circuit the main field rotor winding.  When the voltage across the main rotor winding is of the opposite polarity, diodes limit the voltage buildup.  The transistor which shorts the main field rotor winding is rendered inoperative when the machine is operating at or near synchronous speed.
