Abstract: A chew product for use by animals is made of skin such as rawhide or pigskin. The skin is infused with chlorophyll or mint or both to freshen a dog's breath and also with sugar to increase palatability. The interior portion of the skin can be perforated, such as by cutting, before the skin is formed into a product. The perforations allow a dog's teeth to penetrate into the product and be scraped clean by the edges of the perforations. The skin is dyed green from the chlorophyll. The dyed skin can be used either alone or in conjunction with another color skin to make a product. The dyed skin and a bleached white skin combine to make an attractive product.

Abstract: The end bonnets for a dry expansion heat exchanger of the shell and tube type having a plurality of bundles of tubes. A pair of end bonnets on opposite ends of the shell. Vertical flat impingement plates between the horizontal baffle ribs within the bonnets subdivide the bonnets into subchambers corresponding to the tube count in respective tube bundles. The cross-sectional areas of successive bundles of tubes increase to allow for expansion of the coolant as it flows through the heat exchanger and absorbs heat from the fluid to be cooled. The vertical plates in the end bonnets define restricted flow areas for the coolant which increases in flow area corresponding to the respective tube bundles.

Abstract: Pigskin is processed to provide a bleached, expanded skin used in dog treat or chew products. The raw pigskin is dehaired and then daubed with an alkali mixture of an alkali liquid, alkali enzymes and lime, the mixture having a pH of greater than or equal to 12. The alkali mixture dissolves the colloidal protein. The alkali is removed by alternately rinsing the skin in water and agitating the skin with first ammonium chloride, or chloride sulphate or ammonium sulphide, and then second with ammonium chloride, or chloride sulphate or ammonium sulphide, and pancreatic enzymes. The skin is agitated with sodium carbonate and a degreaser to remove the fat. The skin is then washed with hydrogen peroxide, which bleaches and expands the skin. The skin is then formed into a dog product and dried.

Abstract: Using micro-resistivity techniques, an image of the wall of a borehole can be obtained. A downhole tool stack is provided with plural imaging tools, wherein each imaging tool has a set of pads that deploy radially outward to contact the borehole wall to obtain the image thereof. As the pads deploy outwardly, gaps are formed between the pads. The pads of one tool are circumferentially offset relative to the pads of the other tool so that more complete circumferential coverage of the borehole wall is obtained during the imaging process. Furthermore, an adaptive polling technique is utilized to telemeter the large amounts of data generated by the two imaging tools to the surface. Data is obtained from the imaging tools by polling at a particular rate, which rate is modified depending upon the amount of data generated by the imaging tools.
