Patent number: 8172692Abstract: A thread forming screw having a minimum surface hardness of HRC 56. The screw can form threads in a workpiece having a surface hardness which exceeds HRC 23. A method of surface hardening a screw includes carbon enriching the screw to at least a 0.48 carbon level, and then quenching the screw. Then, the screw is tempered such that the surface hardness does not exceed the core hardness by more than 3 Rockwell C points, and both the surface and core are at a Rockwell C33-C39 hardness. Subsequently, the point is induction hardened, and the screw is quenched again. The screw is again tempered such that the lead threads and the first 3-4 full threads are at a Rockwell C56 minimum hardness, preferably to a depth of at least 0.008 inches, and the core of the fastener is at Rockwell C33-C39 hardness. Finally, a finish is applied.Type: GrantFiled: July 28, 2009Date of Patent: May 8, 2012Assignee: Acument Intellectual Properties, LLCInventors: David R. Price, Gary Shattuck

Patent number: 6632560Abstract: A battery pack for an electric/hybrid vehicle that includes a plurality of batteries stacked in layers one atop the other and electrically coupled together to provide the necessary power to the vehicle. The plurality of batteries is supported on an underlying base. A plurality of spacers are disposed above and below each layer for separating the layers of batteries and providing air passages around the batteries to allow air flow around the batteries to provide heating or cooling of the batteries. A retention frame affixes the batteries to the base to restrict movement of the batteries. The frame includes a plurality of beams that are interconnected and extend along the ends of the batteries. The beams apply a vertical force against the batteries, thereby fixing them rigidly to the base.Type: GrantFiled: January 29, 2001Date of Patent: October 14, 2003Inventors: Shijian Zhou, Jeffrey C. Waters, David R. Price

Patent number: 6569556Abstract: A battery pack for an electric/hybrid vehicle including a cooling system that provides a substantially uniform cooling of the batteries within the pack. The battery pack includes a base that supports the batteries stacked in layers one atop the other. Each battery includes a plurality of cells with cooling air channels between them. A retention frame overlays and is affixed to the batteries to restrict the movement of the batteries within the pack. The batteries are held in spacers disposed above and below each layer of batteries. The spacers provide air passages above and below the batteries to allow cool air to flow across the batteries and through the cooling channels. An inlet admits cool air into the pack and an outlet releases the air from the pack after it is has passed through the stack of batteries. A front manifold is connected to the inlet and includes a plurality of separate runners for evenly splitting the air between the spacers below each layer of batteries.Type: GrantFiled: January 29, 2001Date of Patent: May 27, 2003Assignee: General Motors CorporationInventors: Shijian Zhou, Jeffrey C.

Patent number: 5956945Abstract: A method and apparatus converts time-resolved sensor signals into transfer functions and/or cumulative transfer function signals which can be attained by computation means such as by using Fast Fourier Transforms. A signal, as a means to assess catalyst performance such as a signal based on sensing oxygen concentration or air to fuel ratio or hydrocarbon concentration in motor vehicle exhaust in accordance with the present invention is in the time domain and has multiple components at different frequencies. The use of Fast Fourier Transforms isolates the various spectral densities which arise from different frequency components of the complex time domain signal. Cross spectral density function and power spectral density function are used to determine the transfer function. The analysis has been found to be substantially independent of operating conditions. The transfer function and cumulative transfer function have been found to be a precise indication of the catalyst performance.Type: GrantFiled: November 14, 1997Date of Patent: September 28, 1999Assignees: Engelhard Corp., Motorola, Inc.Inventors: Sanath V.

Patent number: 5255653Abstract: An engine throttle control system comprises a control unit for controlling the position of a throttle by means of a motor in response to a position transducer actuated by an accelerator pedal. A detector detects when a signal produced by the control system is outside a range of acceptable values and, for instance, shuts down the engine. In one embodiment, the detector detects whether power supplied to the motor is less than a value expected on the basis of the position and speed of movement derived from the output of a throttle position sensor.Type: GrantFiled: March 15, 1993Date of Patent: October 26, 1993Assignee: Lucas Industries Public Limited CompanyInventors: John M. Ironside, Peter M. Fox, Alistair M. McQueen, David R. Price

Patent number: 4587968Abstract: An electric emasculator for castrating a bull calf or the like having a first scissor member pivotally connected to a second scissor member. The second scissor member has a structure defining a bifurcated fork with a pair of parallel upper edges. A heating element is positioned along one of the parallel upper edges to cauterize as an incident to the severing operation and assists in the blood coagulation to prevent the flow of blood and closure of blood vessels in the area of amputation. A method for castrating the bull calf includes registering the end of an arcuate-L shaped hook of the first scissor member with the bottom structure of the bifurcated fork simultaneously to lodging a crushing block, that is integrally bound to the first scissor member, against the top of a second cutting edge.Type: GrantFiled: March 19, 1984Date of Patent: May 13, 1986Inventor: David R.
