Patent CA-2389866-A1 (CA)
Inventor: WILSON IAN
IPC: C22B21/00
Filed: 2000-11-14
Abstract: Application of a marking agent to metal stock, such as aluminum sheet, during and as a part of procedures for preparing the sheet for subsequent, scrap-generating manufacturing operations, to provide a detectable mark on pieces of manufacturing scrap derived from the marked sheet and commingled with scrap of other aluminum alloy sheet, so that the scrap can be sorted and the marked alloy scrap pieces separated from scrap of other alloy sheet to which the marking agent was not applied. Different marking agents, providing detectably different marks, may be respectively applied to sheet of different compositions if scrap pieces of more than two different compositions or compositional families are to be sorted and separated from each other. The marking agent may be added to a lubricant or prelubricant conventionally applied to the sheet by the sheet producer prior to delivery to the manufacturing customer.

Title: Insulated heat shield
Inventor: CHEN COLIN CHING-HO
IPC: F01N13/14
Filed: 2002-06-11
Abstract: A heat shield provides thermal insulation and reduced noise transmission for under-the-hood vehicular engine components, such as exhaust manifolds. The structure is formed in three layers: an outer metal layer to provide structural integrity, a center insulation layer to isolate heat and dampen noise, and an inner metal layer directly adjacent the shielded component for reflecting heat back to the shielded component. As disclosed, the insulation layer is sandwiched between the two metal layers. The heat shield is formed in two integral mating halves to define a unitary structure containing grommets. The grommets incorporate capscrews rotatably secured in respective halves of the structure for attachment to mounting bosses on the component. Finally, the edges of the two metal layers of the heat shield are folded over to prevent injury to installers, and to reinforce the heat shield structure for enhancing its useful life under severe conditions of vibration and heat.

Patent CA-2410002-A1 (CA)
Inventor: DAIKOKU KAZUHIRO
IPC: H04H40/36
Filed: 2002-10-24
Abstract: The invention addresses itself to the task of providing a medium-frequency stereo broadcast receiving circuit that does not require any alteration of the radio wave format used in the medium-frequency stereo broadcast system that has become the de facto standard, and that receives transmitted broadcast waves and removes, in the course of the demodulation process, disturbance that has affected the signal during its propagation, thereby improving the audio quality of the demodulated signal and obtaining the full potential of the stereo effect. To achieve this, the received medium-frequency stereo broadcast wave is converted to a single-sideband signal, and the sum signal (L + R) is demodulated from the phase term of this converted single-sideband signal. The difference signal (L - R) is demodulated from the phase term of the received medium-frequency stereo broadcast wave and from the demodulated sum signal output.

Title: Agitating and anti-bridging device for waste toner in a xerographic printing apparatus
Inventor: HART STEVEN C
IPC: G03G21/10
Filed: 2003-06-17
Abstract: In a cleaning station for removing residual toner from a photoreceptor in a xerographic printing apparatus, the residual toner accumulates in a hopper, and an auger at the bottom of the hopper removes the accumulated toner. A thin, flexible member forming an agitator extends nearly vertically from the top of the hopper to the auger. Fingers at the end of the agitator contact the flights of the auger. There are between one and three more fingers than there are flights of the auger: the discrepancy causes an undulation of the agitator when the auger rotates.
