Abstract: APPARATUS FOR ROLLING CURVED SECTIONS            Abstract of the Disclosure A metal sheet is formed into an arcuate contour by rolling the sheet under high pressure on an elastomeric pad (24) supported by a rigid frame.  A pair of laterally spaced rollers (30, 32) are used to form the arc.  Each moves from the transverse edge of the sheet inwardly and crosses the center line of the sheet.  Under the high pressure applied to the rolls the sheet yields to form the arc and the elastomeric material elastically deforms as the arc is formed.  The rollers depend from vertical guides (34, 36) which follow a track extending transversely across the sheet. A guide track (38) is provided in a transverse beam located above the rolls and the guides.  Hydraulic or pneumatic jacks (70) apply pressure to the beam which in turn applies pressure to the rolls.

Abstract: ABSTRACT    The production of improved germanium photo-responsive amorphous alloys (118, 146, 168, 180, 194, 206, 208, 210, 214, 216, 218, 220) and de-vices, such as photovoltaic (142, 168, 198, 212) photoreceptive devices (178, 192) and the like is made possible by adding at least one density of states reducing or altering element, fluorine, to the alloys (118, 146, 168, 180, 194, 206, 208, 210, 214, 216, 218, 220).  The altering element or elements are added to the germanium amorphous alloys (118, 146, 168, 180, 194, 206, 208, 210, 214, 216, 218, 220) either during or after the deposition thereof.  Band gap adjusting element(s) can also be added.  One adjusting element is car-bon which increases the band gap from that of the materials without the adjusting element incorpo-rated therein.  Other adjusting elements can be used such as nitrogen.  The germanium and adjust-ing elements are concurrently combined and de-posited as amorphous alloys (118, 146, 168, 180, 194, 206, 208, 210, 214, 216, 218, 220) by vapor deposition, sputtering or glow discharge decompo-sition.  The addition of fluorine bonding and electronegativity to the alloy (118, 146, 168, 180, 194, 206, 208, 210, 214, 216, 218, 220) acts as a compensating or altering element to reduce the density of states in the energy gap thereof.          The fluorine bond strength allows the adjusting element(s) to be added to the alloy (118, 146, 168, 180, 194, 206, 208, 210, 214, 216, 218, 220) to adjust the band gap without reducing the elec-tronic qualities of the alloy (118, 146, 168, 180, 194, 206, 208, 210, 214, 216, 218, 220).  Hydrogen also acts as a compensating or altering element to complement fluorine when utilized therewith.  The addition of the adjusting element(s) to the alloys (118, 146, 168, 180, 194, 206, 208, 210, 214, 216, 218, 220) adjusts the band gap to a selected opti-mum wavelength threshold for a particular device (142, 168, 198, 212, 178, 192) to increase the photoabsorption efficiency to enhance the device's photoresponsiveness without adding states in the gap which decrease the efficiency of the devices (142, 168, 198, 212, 178, 192).  The adjusting element(s) can be added in varying amounts, in discrete layers or in substantially constant amounts in the alloys (118, 146, 168, 180, 194, 206, 208, 210, 214, 216, 218, 220) and devices (142, 168, 198, 212, 178, 192).

Abstract: ABSTRACT OF THE DISCLOSURE: Gelation and setting of desirably miscible and pumpable aqueous crutcher slurries comprising sodium bicarbonate, sodium silicate and sodium carbonate are retarded and often are prevented by the novel addition of sod-ium sesquicarbonate (which serves as a source of sodium carbonate and sodium bicarbonate) after admixing of sodium bicarbonate, sodium carbonate (if added earlier) and sodium silicate.  Desirably, citric acid is dissolved in the crutcher medium before addition of the sodium sesquicarbonate but its presence is not necessary.  The method of the invention appreciably increases workable crutcher time (stabilizes the mix against gelation) compared to prior methods of manufacturing similar crutcher mixes of similar contents of bicarbonate and carbonate (considering the sesquicarbonate of the present method as a source of carbonate and bicarbonate), whether all the carbonate and bicarbonate are separately added to the crutcher before the silicate or are added partially before and partially after silicate addition.  The improved  workability and stability of the crutcher mix permit the making of higher solids content crutcher slurries, therby result-ing in significant energy savings and increases in production rates when such slurries are subsequently spray dried to produce free flowing inorganic salt base beads, from which beads built or heavy duty detergent compositions may be made by post-spraying onto the base beads a nonionic synthetic organic detergent in liquid state.

Abstract: CRYOGENIC CABINET FREEZER                   ABSTRACT A cabinet cooler or freezer which efficiently utilizes cryogenic refrigeration either with or without mechanical refrigeration.  The freezer intermittently freezes relatively large batches of product by efficiently utilizing the natural expansion effect of a liquid cryogen, in combination with mechanical circulation by blowers, to create an overall circulation that efficiently removes heat from the product.  A secondary circulation effect is induced, in a manner similar to the operation of a jet pump, which amplifies the circulation and allows CO2 to be employed as the cryogen with modulating valve control to achieve uniformly low temperature throughout the cabinet without snow build-up on the cabinet bottom.  Some cabinet versions create a cyclonic circulation pattern about a vertical axis that is particularly effective.

Abstract: Abstract of the Disclosure Concretes containing a hydratable cementitious binder such as Portland cement and a high strength aggregate material are described.  The high strength aggregate material is produced from hydrated cementitious compositions which contain relatively low proportions of Portland cement and relatively high propor-tions of a select fly ash component.  The high strength aggregate material is produced by mixing the aforementioned Portland cement and fly ash components with water and allowing such to hydrate.  The hydrated aggregate product may then be reduced in size (e.g. by crushing) and screened prior to combination with the cementitious binder to produce concrete compositions.  Concretes can be prepared with such aggregate which have at least comparable compressive strengths to concrete prepared using conventional crushed stone aggregate.
