Abstract: ABSTRACT OF THE DISCLOSURE                  A heat receiver is provided comprising a housing through which the breathing mixture passes in one direction and through which the exhaled breath passes in the opposite direction.  The housing contains heat conductive elements through which the breathing mixture and exhaled breath pass and spacers positioned one between each pair of adjacent heat conductive elements.  The spacers are poor heat conductors and non-hygroscopic to minimize moisture retention.  In use, exhaled breath warms the heat conductive elements sequentially so that each element will be slightly cooler than the last element exposed to the exhaled breath. There will be minimal heat stored in the spacers and the moisture content of the exhaled breath tends to be carried through the device so that upon drawing breathing mixture through the device a substantial part of the sensible heat originally in the exhaled breath will be reclaimed by the breathing mixture.  The latent heat originally in the ex-haled breath will be lost.

Abstract: Abstract of the Disclosure A pipeline switch is provided which is particularly useful in the foodstuff industry.  The switch has leakage control and a cleanable leakage cavity.  Two differently sized valve disks are movable independently relative to one another to a limited extent.  One disk is rigidly connected to the pipeline switch drive and when lifted positively moves the other with it.  The valve rods of the valve disks extend in the same direction and telescopically engage one another.  The valve disks form between them both in the closed and in the open position, a leakage cavity with one or two connecting paths to the exterior of the pipeline switch.  This path (or paths) serves both for the leading away of the leakage fluid and for the feeding or discharge of the fluids used in the cleaning process.  An annular clearance is formed by the valve rod connected to the smaller valve disk and the hollow valve rod which leads from the larger valve disk.  This annular clearance is throughout its entire length an integral part of a connecting path between the leakage cavity and the exterior of the pipeline switch.

Abstract: PRODUCTION OF DICED HOT BANANA PEPPERS            Abstract of the Disclosure A process is described for preparing diced hot banana peppers which avoids the usual manual procedures of slicing and removing seeds and pulp.  According to the novel method, stems are removed and the peppers are washed in the usual manner, but these washed peppers are then passed directly through a commercial dicing machine to produce a diced mass of material including diced vegetable flesh, pulp and seeds.  This diced mass is then fed in one end of a cylindrical revolving screen sizer wherein the seeds and pulp are separated from the diced vegetable flesh by passing through the screen to waste while the diced vege-table flesh remains on the screen.  The diced vegetable flesh    substantially free of the undesirable pulp and seeds is then collected from the screen and can be directly frozen or pickled for use by the consumer.

Abstract: ABSTRACT OF THE DISCLOSURE         In an alternating current electric power system of the type subject to rapid load voltage regulation as a result of variations in reactive load current, reactive load current compensation is provided by fixed capacitors and inductors in parallel with the load, the inductors being in series with static switches which are phase controlled to continuously maintain the net reactive compensating current substantially equal and opposite to the reactive component of load current. Compensation control determines firing time of the static switches in accordance with the magnitude of reactive load current. Regulating means additionally controls firing time to maintain line current and line to neutral voltage at a sel-ected line location substantially in phase coincidence. The regulating means is provided with means for enhancing the stab-ility of the system under no load or light load conditions. In a preferred embodiment, regulation stability is enhanced through the application of a small real or, in phase current signal whenever the real or in phase component of actual line current at the selected line location is less than a predetermined level which is desirable for stable regulation of the power system.
