Patent CA-2026953-A1 (CA)
Inventor: OLANIRAN MOSES A
IPC: B23D31/00
Filed: 1990-10-04
Abstract: Abstract of the Disclosure A method consisting essentially of three steps, each of which may be subdivided.  The steps include (a) forming a ductile metal (steel, aluminum or titanium) connecting rod in one piece (e.g., by hot forging) having an annular wall defining a crankshaft opening with preformed surface crevices for guiding the initiation of a cracking plane that extends across the crank opening; (b) charging (i.e., for about 40 seconds) the region of such wall along at least one portion of the cracking plane with hydrogen by means of an electrolytic cell or by means of reacting the metal rod with a strong acid (e.g., concentrated sulfuric) to cause hydrogen to dissolve in the metal to facilitate hydrogen stress cracking thereat, with or without the imposition of static mechanical tensile loading at such crevices (i.e., for about 40 seconds) of a magnitude insufficient to cause yielding of the metal; and (c) prolonging, increasing, or imposing the static mechanical loading (i.e., for another 40 seconds) at the crevices to effect fracture across the entire cracking plane and thereby separate the connecting rod into a rap and body with rough, fractured mating surfaces.

Title: Controlling mineral deposits in cooling systems
Inventor: COUGHLIN MICHAEL F
IPC: C02F5/14
Filed: 1991-07-29
Abstract: ABSTRACT OF THE DISCLOSURE         While chelants such as ethylenediaminetetraacetic acid (EDTA) have been used for preventing scale deposition in boiler water, because of the expense it has not been used in cooling water treatment.  It has been found that a relatively small quantity of a chelant can be used in combination with a scale deposit control agent such as a phosphonate to prevent scale deposition in cooling water.  A preferred composition including a 4.5:1 ratio by weight of hydroxyethylene diphosphonic acid (HEDP) to EDTA displays a synergistic effect when used for scale prevention.

Abstract: A  cellular mobile  station  is  operable  in  a telephone mode and a time data display mode.  During the time display mode, the station constantly receives an area identifying  code  transmitted  from  a  cellular  mobile communications system.   On crossing a boundary between adjoining cell-site areas,  a time difference value  is entered  from  a  keypad  into  a  location  of  a  memory corresponding to the received code.   This  process  is continued on  a  learning basis  to  store  as many  time difference values into the memory as there are cell-site areas along the route of a journey.  Following the learning process,   the  station  constantly  receives  an  area identifying  code  and  recalls  one  of  the  stored  time difference data from the memory corresponding to a code received on crossing a boundary and modifies displayed timepiece data with the recalled time difference.
