Title: Switched power regulator
IPC: H02M1/00
Filed: 2009-10-27
Abstract: Methods and apparatus for control of DC-DC converters, especially in valley current mode. The DC-DC converter is operable so that a low side supply switch may be turned off, before the high side supply switch is turned on. During the period when both switches are off the current loop control remains active and the change in inductor (L) current is emulated. One embodiment uses a current sensor for lossless current sensing and emulates the change in inductor current by holding the value of the output of the current sensor (ISNS) at the time that the low side switch turns off and adding an emulated ramp signal (VISLP) until the inductor current reaches zero. Embodiment employing a pulse-skip mode of operation based on a minimum conduction time are also disclosed. The invention enables a seamless transition from Continuous Conduction Mode the Discontinuous Conduction Mode and Pulse Skipping and provide converters that are efficient at low current loads.

Title: Elements & devices for assembly of electronic components
IPC: H05K3/40
Filed: 1986-08-01
Abstract: A chip carrier mounting device which is hereinafter also referred to as an "interconnection preform placement device" includes a retaining member having a predetermined pattern of apertures in which are positioned preforms of joint-forming material such as solder.

Patent GB-9324391-D0 (GB)
Title: Device for transmission of one-way torque
IPC: A61M15/00
Filed: 1993-11-26
Abstract: A device for the transmission of one-way torque comprising an outer annular member having a plurality of radially inwardly projecting teeth each comprising a driving surface and a cam surface, and a shaft concentrically mounted with respect to the outer annular member and comprising a plurality of drive elements each having a driving surface and a cam surface. Rotation of the shaft or outer annular member in its driving direction causes engagement of a driving surface of at least one drive element with a driving surface of at least one tooth thereby resulting in joint rotation of the shaft and outer annular member. Rotation of the shaft or outer annular member in its non-driving direction causes engagement of the cam surface of at least one drive element with the cam surface of at least one tooth resulting in additional relative movement, substantially radially, between the drive element and tooth, thereby preventing rotational movement being transmitted between the shaft and the outer annular member.

Title: Short range ultrasonic distance warning system
IPC: G01S15/931
Filed: 1995-07-10
Abstract: A short range ultrasonic distance warning system is used as a parking aid in a motor vehicle. The entire system is active in the case of reverse gear being selected and low speed, and is deactivated automatically at higher speed.

Title: Dispenser pumps
IPC: F04B53/10
Filed: 1998-09-25
Abstract: A fixed-nozzle dispenser pump suitable for large doses has a downwardly-directed nozzle tip (32) and an outlet valve arrangement (4) in a nozzle (3). A blocking element, such as a ball (41), of the outlet valve arrangement (4) is biased back along a close-fitting tubular draw path (43) in the valve after dispensing, so as to draw product back out of the nozzle tip and prevent dripping. A further feature is a subdivision of the nozzle tip and a flexible flap valve (35) blocking a resulting passage segment in the nozzle. This facilitates clearance of another nozzle passage (36) by the reverse suction. A further feature is a membrane (24) across the front of the piston plunger, advanceable relative to a piston seal (231) by pressure of a plunger head (21). This helps accomomodate the returned fluid and enables a spot-dosing action.
