Patent number: 9552356Abstract: Techniques described enable creation of a single log containing information from both server-side and client-side logs. A logging service receives page requests and other data from a user operating a computing device. These page requests are then stored in a server-side log. The logging service also receives interactions made by the user on a displayed page. These interactions are then stored in a client-side log separate from the server-side log. The logging service then converts a format of the data in the client-side log and merges the client-side and server-side logs to form a single log. A service provider may then analyze this single log to track how this and other users navigated the pages associated with the page requests.Type: GrantFiled: December 21, 2007Date of Patent: January 24, 2017Assignee: Amazon Technologies, Inc.Inventors: David J.

Patent number: 6213264Abstract: An improved camshaft sealing arrangement includes seals at each end of the camshaft housing. In addition, seals and washers are positioned between the camshaft and the slack adjuster connection. The combined seals provide a camshaft that is less likely to require maintenance than prior art camshafts. The seal adjacent the cam contacts an outer periphery of the camshaft housing. This seal also provides a thrust bearing washer surface against the camshaft. The seals between the camshaft and the slack adjuster include washers to properly secure and position the seals, the camshaft and the slack adjuster.Type: GrantFiled: October 15, 1996Date of Patent: April 10, 2001Assignee: Meritor Heavy Vehicle Systems, L.L.C.Inventors: Donald G.

Patent number: 5772801Abstract: In a process for the forming of wheel rims in metal alloy, a cast blank undergoes a cold chip removal process by cutting its central area, its inner surface and its lateral surface in order to obtain a semi-finished work which is then heated and plastically deformed by flow forming along its lateral surface to obtain an inner edge, an outer edge and a middle portion with a defined machine allowance; the rim thus obtained undergoes another cold chip removal process by cutting in order to work it down to the required size; the latter process may be preceded by solution and age hardening heat treatments.Type: GrantFiled: September 23, 1996Date of Patent: June 30, 1998Assignee: Reynolds Wheels S.p.A.Inventors: Valter Baldi, David J.

Patent number: 5649612Abstract: An improved bracket member for a vehicle brake system is disclosed. The bracket member has a wing bracket at one end for mounting of a brake actuating mechanism and a mounting plate at the opposite end for connection to the spider of the brake assembly. A hollow tubular member is positioned between the wing bracket and mounting plate and securely affixed to each of them, such as by welding. The tubular member can be of any length depending on the vehicle and applicable clearance space. The mounting plate is secured such as by fasteners to the brake assembly. Also, the tubular member protrudes through the mounting plate and is adapted to be separately securely connected to the brake assembly. The end of the tubular member can be securely attached to an opening in the brake assembly in a number of ways, such as by an interference fit, press fit, wedge fit, compression fit in combination with a spanner nut, pinch joint or the like. The end of the tubular member can also be knurled or splined.Type: GrantFiled: April 3, 1996Date of Patent: July 22, 1997Assignee: Rockwell International CorporationInventors: Donald G. Walker, David J. Dettloff, David J. Edwards

Patent number: 5607034Abstract: An improved brake shoe table includes the edges of the brake shoe table being bent radially inwardly relative to the remainder of the table by between 45 and 90 degrees. The bent edges increase the rigidity of the brake shoe and also reduce localized lining wear by bringing the lining into contact with a brake drum in a more uniform fashion. Moreover, the improved brake shoe design has unexpectedly decreased the operation noise associated with the use of a cam brake system.Type: GrantFiled: March 8, 1995Date of Patent: March 4, 1997Assignee: Rockwell International CorporationInventors: David J. Edwards, Donn C. Knight, Jonathan L. Wemple

Patent number: 5599150Abstract: A hitch pin for maintaining a clevis pin in a bore including a continuous wire member formed to include a straight portion ending in a constant radius hinge portion. A parallel portion extends from the hinge portion to a constant radius barb portion. The termination of the barb portion is located on the side of the straight portion opposite the parallel portion and resiliently maintained there by properties of the hinge portion as accentuated by material properties of the wire itself. The hitch pin may be installed in a bore defined in a clevis pin by applying force to the hinge portion after inserting the leadin portion in the bore. During installation, the barb portion is resiliently deformed about the clevis pin and returns to a preinstalled position when the hitch pin installation has been completed. Any forces attempting to remove the hitch pin cause the barb portion to strike the clevis pin presenting a mechanical obstruction to removal.Type: GrantFiled: August 31, 1994Date of Patent: February 4, 1997Assignee: Rockwell International CorporationInventors: David J. Edwards, Charles Giacomazza

Patent number: 5310098Abstract: Molten metal is either poured or injected into the cavity of a permanent mold by way of a bush which comprises a metal sleeve, anchored to the mold itself, a first tubular element of ceramic material lodged internally of the sleeve, and a second tubular element, also ceramic, coaxial with the first. The stream of metal passes from a feeder into the inlet end of the bush, through the first and then the second ceramic element, and enters the cavity ultimately from an outlet end consisting of a metal annular element connected in a precise and effectively fluid-tight fit with the corresponding end of the second tubular element.Type: GrantFiled: February 17, 1993Date of Patent: May 10, 1994Assignee: Reynolds Wheels S.p.A.Inventor: David J.

Patent number: 5305856Abstract: An automatic slack adjusting mechanism for a rotary oscillatory cam actuated brake assembly including an elongated housing having an opening therethrough and a bore, a worm gear rotatably mounted in the opening, a shaft mounted for rotation in the bore and having a worm nonrotatably secured thereto and drivingly engaging the gear. A detent part in the housing is axially fixed relative to the bore and a link is pivotally connected to one end of a plunger assembly and to the housing whereby pivotal movement of the link relative to the housing will move the plunger assembly relative to the detent part and the detent will rotate the plunger, the worm and the worm gear upon return movement of the plunger assembly following outward movement of the assembly beyond a predetermined distance relative to the detent. The detent part includes a spring biased pawl extending into toothed engagement with a helical toothed surface portion of the plunger.Type: GrantFiled: September 29, 1992Date of Patent: April 26, 1994Assignee: Rockwell International CorporationInventor: David J.

Patent number: 5173430Abstract: In a method for determining the dry matter content and nutritional value of moist vegetable material, such as silage, liquor is expressed from a sample of known quantity by applying thereto a reproducible pressure regime, the quantity of expressed liquor is measured, and the expressed liquor is analyzed for parameters, such as pH, ammonia, lactic acid, free sugar and alpha-amino nitrogen, from which the nutritional value can be estimated by regression. The nutritional value of silage can be expressed in terms of its fermentability in the rumen. The invention includes a portable facility for use in `on farm` analysis of silage to determine its nutritional value.Type: GrantFiled: January 22, 1991Date of Patent: December 22, 1992Inventors: David J.
