Title: Pressure casting of battery terminals
Inventor: RATTE ROBERT W
IPC: B22D25/04

Abstract: ABSTRACT OF THE DISCLOSURE A closed system and method that includes a source of pressurizeable molten lead connected to a mold having a mold cavity therein with the mold maintainable at sufficiently low temperature so that a charge of molten lead located in the mold cavity solidifies to thereby form a solidified casting in the mold cavity. A housing having a runner, is maintainable at sufficiently high temperature to maintain the molten lead in a molten state so that the mold cavity can be refilled with a fresh charge molten lead when a solidified casting is removed therefrom without introducing air to the closed system. A shut-off valve, having an open position to allow a charge of molten lead to flow into the mold cavity and a closed position to prevent molten lead from flowing out of the runner as the molten lead in mold cavity solidifies with the shut-off valve configurable to intensify the pressure of the lead in the mold cavity. The intensification mode being monitorable so that when the state of molten enters a liquid-to-solid transformation stage, the volume of the mold available for the lead to solidify therein is quickly reduced through a volume contraction step to thereby cause the molten lead to flow into the remaining volume at the same time one maintains pressure on the molten lead. As the molten lead solidifies under the reduced volume and high pressure it produces a battery part that is substantially free of both tears and cracks. In an alternate intensification method, the lead is allowed to solidify and at least a portion of the lead is mechanically deformed through a volume contraction step to cause cracks or tears in the battery part to be eliminated thereby providing a battery part free of cracks or tears. In another method of forming a pressure cast battery part free of cracks a molten lead under pressure is flowed into a battery part cavity and the pressure of the molten lead is increased to sufficiently high pressure so that when the molten lead solidifies it forms a battery part free of cracks and voids. 21

Abstract: The invention concerns a method for producing alumina trihydrate by decomposing in the presence of an supersaturated sodium aluminate liquor (1) derived from a BAYER process chain characterised in that it consists in applying at the beginning of the decomposition (A) an intense mechanical action in the supersaturated aluminate suspension (3). The mechanical action is carried out at the start of decomposition, for example in the priming tank (A) or in one or several circuit(s) recirculating the supersaturated aluminate suspension (3) above the priming vessel. The mechanical action is carried out by grinding, by transmitting high power ultrasounds, by a shearing turbine or by an additional centrifugal pump (P) recirculating with high flow rate the aliquot above an auxiliary tank. When an auxiliary tank is used, a supersaturated aluminate liquor is advantageously mixed with the suspension to be treated. The method is also applicable to American type decomposition chains.

Abstract: This invention is related to tandem free operation (TFO) in mobile cellular systems. The present invention implements a tandem free operation by using a special feedback loop which makes the decoded parameters available, performs the comfort noise insertion and bad frame handling operations, produces the parameter quantisation indices corresponding to the output of these operations, and synchronises the speech encoders and the speech decoders in the transmission path from the uplink mobile station to the downlink mobile station. This functionality is realized by partly decoding and re-encoding the parameters and synchronising and resetting the quantiser prediction memories in a specific manner. A basic idea of the invention is, that during BFH and CNI processes, a re-encoding block produces models of encoded speech parameters from the BFH/CNI processed speech parameters. These models of encoded speech parameters are then transmitted to the receiving end. The present invention provides a solution to the problem created by predictive, more generally non-stateless encoders in TFO operation.

Granted: 2005-04-26
Abstract: An oil passage extending from an oil pump to a discharge port in an internal combustion engine is, at its halfway point, branched into at least two oil passages, for example, a first oil passage 44 and a second oil passage 45; and one of the at least two branched oil passages, for example, the second oil passage 45 is provided with a restricting portion configured as a first orifice 83 for restricting a flow amount of oil by reducing a diameter of the first orifice 83, and a bypass valve 92 which acts, when a hydraulic pressure in the second oil passage 45 exceeds a specific value, to bypass the first orifice 83 so as to increase the flow rate of oil. It is possible to increase the hydraulic pressure at the time of low speed rotation up to a necessary pressure only by providing the restricting portion, without enhancing the performance of the oil pump. Accordingly, it is possible to suppress the increase in weight and cost of the lubricating system as compared with the prior art lubricating system in which the performance of the oil pump is enhanced, and since it is not required to increase the rotational speed of the oil pump, it is possible to prevent the loss in output of the internal combustion engine due to the increased friction of the oil pump. Further, it is possible to prevent excess increase in pressure of the oil passage by the effect of the bypass valve.

Granted: 2006-05-09
Abstract: An upright vacuum cleaner (A) includes an upright housing section (B) and a nozzle section (C). A cyclonic airflow dirt and dust separating chamber (54) is defined in said upright housing section. A suction source (E) pulls air and entrained dirt, dust, and other contaminants through a main suction opening (26) formed in the underside (24) of the nozzle and into the cyclonic airflow chamber (54). The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container (52) that defines the chamber (54). A main filter element (K) filters residual contaminants from the suction airstream between the chamber and the suction source. The main filter element is preferably made from high-density polyethylene porous filter media. A final filter assembly (F) filters the suction airstream discharged by the suction source to ensure that the air discharged into the atmosphere is contaminant free, including those contaminants introduced into the airstream by the suction source itself.

Abstract: A control system for executing an upshift from an off-going speed ratio to an on-coming speed ratio by controlling the release of the hydraulic pressure from the frictionally engaging element used for the off-going speed ratio and by controlling the supply of the hydraulic pressure to the frictionally engaging element used for the on-coming speed ratio comprises first and second off-going pressure releasing valves 70 and 80, which release the hydraulic pressure of the frictionally engaging element used for the off-going speed ratio, and a linear solenoid valve 60, which controls the operation of the off-going pressure releasing valves. The linear solenoid valve 60 controls the operation of the off-going pressure releasing valves in correspondence to the throttle opening of the engine. In this case, the smaller the throttle opening of the engine, the earlier the timing for releasing the hydraulic pressure from the frictionally engaging element used for the off-going speed ratio is set.
