  • Publication number: 20040184168
    Abstract: A vehicle external mirror assembly (10) comprising a bracket mountable to a vehicle door (8), a mirror head (20) pivotally mounted to the bracket (15), a main rear view mirror (22) mounted to the head (20), and an auxiliary mirror (30) mounted to the head (20). The auxiliary mirror (30) provides the vehicle driver with vision alongside and behind the vehicle when the mirror head (20) is in a folded position.

  • Patent number: 6590427
    Abstract: A digital phase detector that conducts pump up and pump down control signals to a charge pump, wherein each of the control signals has pulses that have a substantially 50/50 duty cycle characteristic when the two input signals, i.e., the input data signal and the feedback clock signal, are substantially in phase. This substantially 50/50 duty cycle output reduces, if not eliminates, inherent problems related to the turn-on delays of the charge pump while maintaining a locked condition. The phase detector may further include an intelligence to detect and handle other situations, such as missing data pulses.

  • Patent number: 5449230
    Abstract: A storage locker apparatus includes a cylindrical structure with a plurality of angularly spaced-apart divider walls extending radially outwards. Each wall has an outer end and openings between adjacent outer ends of the walls. There are doors over each of the openings connected to the structure by hinges. Each door has a lock thereon. The lock may be coin operated.

  • Patent number: 5220295
    Abstract: A Loss of Lock Detector and Re-lock Control function using digital techniques to detect a programmable difference in frequencies over a programmable range. Once Loss of Lock is detected, the Re-lock sequence is initiated and PLLIS, PLLMS & PLLGS are stepped through a programmable sequence. The invention detects the frequency difference by counting down two counters and evaluating the value left in one when the other reaches terminal count using a programmable tolerance of frequency differences before Loss of Lock is declared. The complexity and cost of implementation of the invention is reduced by multiple use of a single down counter. Other features of the invention are disclosed.

  • Patent number: 5160285
    Abstract: An improved separable contact assembly for joining spaced bus bar segments includes first and second contacts arranged above and below and movable with respect to the bus bar segments. The first contact includes a guide lug guided through a guide opening. The second contact includes an extension for receiving the guide lug after it passes through the opening. A clamping screw clamps the contacts to the bus bar segments.

  • Patent number: 4878859
    Abstract: An assembly for supporting an electrical terminal housing on a carrier rail is provided, including a pair of slide members connected with a guide portion of the housing for sliding movement between latched and released positions. The thickness of the guide is slightly greater than the thickness of the slide members to define a gap therebetween. Each of the slide members includes a lower hook portion engaging a leg of the carrier rail when the slide members are in the latched position to connect the terminal housing with the rail, and a spring is connected with the slide members for normally biasing the hook portions toward the latched position. A first abutment is connected with the housing and a second abutment is connected with the slide members, the second abutment being normally vertically offset from the first abutment by a distance corrsponding with the thickness of the gap.

  • Patent number: 4648901
    Abstract: An additive is provided which enables metal additions to be made to aluminum melts with good metal recovery and speed of dissolution. The additive includes a mixture comprising:(a) an aluminum-comprising powder, for example commercially pure aluminum;(b) a powder of one or more metals or alloys comprising the metal or metals to be introduced, for example manganese, chromium, tungsten, molybdenum, titanium, vanadium, iron, cobalt, copper, niobium, tantalum, zirconium, hafnium and silver; and(c) a flux, for example one or more of potassium aluminum fluoride or potassium cryolite, potassium chloride, potassium fluoride, sodium chloride, sodium fluoride, and sodium carbonate.In a preferred form, the additive is a compacted tablet of components (a), (b) and (c), in the weight proportions of about 5%, 75% and 20%, respectively. The additive is especially useful in the method of the invention of introducing one or more metals into a melt comprising aluminum.

  • Patent number: 4029028
    Abstract: A metering device is described which provides for very accurate metering of granular material such as seeds or fertilizer. The device incorporates two main components: a solid casing having a slot with an open side and decreasing cross-section, and a corresponding rotor which frictionally urges material along the slot. The rotor has a resilient surface and can be in the shape of a disc or of a roller to correspond with the shape of the casing. The device allows significant savings in the spreading of granular material over conventional devices.
