Title: Double-ended perfume bottle
Inventor: LEVY JUDY
IPC: B65D1/06
Filed: 1997-02-28
Granted: 2002-06-11
Abstract: A bottle for perfume and the like has two separate compartments. Each of the two interior spaces (S1, S2) has its own closure/dispenser (e.g. spray fitting or pump) (D1, D2), one at each end, so that two different liquids can be contained and dispensed separately in different ways. An outer container space (S1) is defined between an outer wall (W1) and an inner wall (W2); the inner containing space (S2) is inside the inner wall (W2). The inner (W2) and outer (W1) walls are joined where the neck of the inner-wall container meets the bottom of the outer-wall container. The bottle may include end caps (C1, C2) which cover the two closures/dispensers (D1, D2) at either end, for a symmetrical, elongated shape somewhat like a cigar. The end caps (C1, C2) may also double as closures.

Title: Connection system for tube conductors
Inventor: MERCUZOT DOMINIQUE
IPC: H01R4/36
Filed: 1997-04-03
Granted: 2005-10-18
Abstract: A tube conductor (6), for example made of copper, is interconnected to a connector housing (10), for example made of aluminun alloy, by stuffing an insert (8), for example a steel ball, into the tube. The steel ball expands the tube and clamps it in the cavity (12) of the housing (10). This construction enables elastic energy to be stored that increases the reliability and lifetime operation of the connector. It also enables a copper conductor to be reliably connected to aluminum connector, even though their thermal expansion coefficients differ, by suitable choice of material and dimensioning of the insert (8).

Title: Apparatus and method for enhancing evacuation of bulk material shipper bags
Inventor: WILCOX DONALD E
IPC: B65D88/16
Filed: 1999-01-27
Granted: 2004-10-12
Abstract: A pillow bag is modified to include an air input port that allows inflation of an interply region of the bag. As the interply region inflates, an inner ply rises and becomes an advancing wall, raising the bulk material level in the bag, inclining the bottom of the bag, and pulling excess material away from the drain port all at the same time. In another embodiment, the pillow bag is made with half the initial number of layers folded in half to create the upper and lower plies and the non-fold edges are bonded. Where comer drain ports are used, the bag can be arranged so that an interlayer bond parallel to the fold is parallel to a diagonal of a tote in which the bag sits and so that the interlayer bond is opposite the drain port to enhance bag evacuation. An additional optional feature of the invention is the inclusion of an integral filling conduit or snout on the top of the bag, a mouth of which acts as a fill port to ease filling of the bag.      The invention can also be applied to fitted bags.

Abstract: A digital communication system (fig. 1) is disclosed which is unique in that it modulates a sinusoidal carrier with discrete cosine segments (fig. 13). The discrete cosine segments may contain different time and amplitude values. The discrete cosine segments may be combined with each other (fig. 13) or with zero slope level segments (fig. 12) in order to effectively modulate the sinusoidal carrier. Rather than employing the use of filters (20) for controlling instantaneous voltage changes, the present communication system (fig. 1) forces the bit edges of the discrete cosine segments to occur at the zero slope points of a cosine wave, where no voltage changes occur. The communication system (fig. 1) utilizes direct digital synthesis (12, 14, 15, 16) in order to create a carrier signal which closely represents sinusoidal carrier signal. The present communication system (fig. 1) may be used in conjunction with various conventional methods such as phase shift keying (fig. 12) and amplitude shift keying (fig. 13). Means (fig. 5) are also provided for demodulating the carrier signal in order to recover the original baseband signal.

Abstract: An encoder-modulator (12, 13, 15) for coupling a digital baseband television signal to a VSB digital television receiver (24) that includes filters (26), equalization circuitry (30) and forward error correction circuitry (31) for correcting signal impairments that are below a given threshold. The encoder modulator processes the baseband signal for low power transmission on an RF channel with less-than-nominal bandpass characteristics. A coaxial cable (23) or other low noise communication link directly connects the RF signal to the RF input of the television receiver (24). Any errors or signal impairments in the transmitted signal that are below the predetermined threshold are corrected by the filters and equalization circuitry built into the VSB digital television receiver (24).

Abstract: A method of removing hot corrosion products from the surface of a component exposed to corrosive conditions at elevated temperatures, as is the case with turbine, combustor or augmentor components of gas turbine engines. The method is particularly suited for the removal of hot corrosion products from components protected with a diffusion aluminide coating, either as an environmental coating or as a bond coat for a thermal barrier coating (TBC). The processing steps of the method include immersing the component in a heated liquid solution containing acetic acid, and then agitating the surfaces of the component while the component remains immersed in the solution. In this manner, hot corrosion products on the surfaces of the component are removed without damaging or removing the diffusion aluminide coating. As a result, regions of the component from which the hot corrosion products were removed can then be repaired by a suitable aluminizing process.

Abstract: An electrical control unit ECU controls a shift thrust Ft applied to a variable width drive pulley 11 through a control valve CV and makes the rotational speed Ne of the engine follow a target engine rotational speed Neo to vary the speed change ratio of a continuously variable transmission CVT. In this control, the shift thrust Ft is achieved as sum of a proportional term P and an integral term I, where the proportional term P is determined on the basis of the deviation DNe of the engine rotational speed Ne from the target engine rotational speed Neo, and the integral term I is determined as cumulative sum of the deviation. When the throttle of the engine is closed, the integral term is set larger than when the throttle is open.

Abstract: A demolition tool for impact hammering, impact pulling and prying is provided which includes an elongate handle defining a passage extending therethrough and first and second rods inserted at respective ends of the handle.  The first rod is slidably engaged within the handle and includes a hook at its outer end. The second rod is fixedly secured within the handle and includes a chisel at one end. The chisel can be used for impact chiseling or prying by sliding the first rod to a retracted position, such that its inner end collides with the inner end of the second rod. The hook may used for impact pulling by lifting the handle away from the hook into an expanded position in which the first rod is prevented from leaving the handle by a stopping mechanism. To increase leverage for prying, the tool may be extended to the expanded position. Because the stopping mechanism is within the handle, the risk of injury to the user is reduced. Because the hook and the chisel of the tool are on opposite ends, each implement does not interfere with the utilization of the other.
