Abstract:
Colic can be a particular problem for babies feeding on liquid feed from a feeder bottle. The colic can be formed by air from various sources in the liquid feed. Typically, there is less air in the liquid feed towards the bottom of the liquid feed container in the feeding position than towards the top of the liquid feed. The present invention provides apparatus for drawing milk from the bottom of the feeding apparatus chamber when the feeder is held in the operating position. This is achieved by positioning a flow restrictor for allowing the passage of liquid feed from a main chamber into a flexible feeding teat at a suitable location. The present invention also provides a resiliently-biased cartridge to assist in priming and/or draining of the flexible feeding teat. The present invention also provides a construction in which the flow restrictor is always provided in the correct position regardless of the relative angular orientation of the elements of the feeder. The present invention also provides feeding apparatus that can be easily disassembled to facilitate cleaning.
Abstract:
With reference to FIG. 1, the present invention provides an internal combustion engine which operates repeatedly a multi-stage combustion process, the engine having a combustion chamber, supply means (12) for supplying fuel and air to the combustion chamber and exhaust means (16) for exhausting combusted gases from the combustion chamber. During a first stage of combustion (FIG. 1(a)- FIG. 1(c)) the supply means (12) supplies fuel and air to the combustion chamber and the supplied fuel and air are combusted by a spark ignition Otto process or by a compression ignition Diesel process. Then (FIG. 1(d)) at least a majority of the combusted gases resulting from the first stage combustion are retained in the-combustion chamber, additional air is supplied to the combustion chamber(FIG. 1(e)) and the resulting mixture is combusted in a second combustion stage (FIG. 1(e) and FIG. 1(f))by homogeneous charge compression ignition. The mixture of fuel and air during the first stage combustion is a rich mixture (with an air-fuel ratio λ less than 1) and the mixture of fuel and air and combusted gases during the second stage of combustion is a weak mixture (with an air-fuel ratio λ greater than 1).

The subject invention provides an advertising display assembly (10) including two layers of stock material (12, 28) defining a plurality of outer peripheral edges (42, 44, 46). A release liner (24) is sandwiched therebetween. A plurality of score lines (62) define an integral coupon card (20) within the assembly (10) and an outer strip of material (22) between the integral card (20) and the outer peripheral edges (42, 44, 46). A plurality of mini-coupons (58) are detachably cut into the integral card (20) through the second layer of stock material (28). The assembly (10) is characterized by a hinge (74) extending across the strip of material (22) and defining an upper portion (76) and a lower portion (78) in the strip of material (22). The lower portion (78) of the strip of material (22) rotates relative to the upper portion (76) and the integral card (20) for supporting the assembly (10) on a surface (80) in an upright position for display.
Abstract:
A spun polyester fiber, a drawn polyester yarn, and methods for making them. Polyethylene terephthalate yarn is prepared by extruding a molten melt-spinnable polyethylene terephthalate having an intrinsic viscosity of at least about 0.8 through a shaped extrusion orifice having a plurality of openings to form a molten spun yarn; solidifying gradually said molten spun yarn by passing said molten spun yarn through a solidification zone which comprises (i) a retarded cooling zone and (ii) a cooling zone adjacent said retarded cooling zone where, in said cooling zone, said yarn is rapidly cooled and solidified in a gaseous atmosphere; withdrawing at sufficient speed said solidified yarn from said solidification zone to form a crystalline partially oriented yarn; and hot drawing said crystalline partially oriented yarn at a total draw ratio between about 1.5/1 and about 2.5/1 to produce a drawn yarn having an effective crosslink density (N) between about 10×1021 and about 20×1021 crosslinks per cubic centimeter. The yarns and fibers so prepared may be used to make treated tire cord having high tenacity in combination with improved dimensional stability.
Abstract:
A dry powder delivery system having an elongaged tube containing a matrix having a measured amount of dry particles of therapeutic compound and a porous element having a dessicant therein is disclosed. The porous element with the dessicant can be combined with the powder-containing matrix or the they can be two separate elements. The pressure drop induced by inhalation by the user causes air to flow through the tube and into contact with the particles of dry powder for discharging the particles for inhalation by the user.

The invention provides, for example but not limited to, novel orthogonal synthetases, methods for identifying and making the novel synthetases, methods for producing proteins containing unnatural amino acids, and translation systems.
Abstract:
A radio frequency circuit is generated as an integrated circuit that is arranged to provide transmission, receipt, and storage of data. The data is transmitted and received across a radio frequency band. An antenna is included within the integrated circuit, wherein the antenna is manufactured at the time the integrated circuit is manufactured. A power source is mounted adjacent to the integrated circuit. The integrated circuit and the power source are encapsulated within the same integrated circuit package.
Abstract:
DC power savings in a mobile communication device can be achieved by dynamically adjusting the biasing for a receiver based on the communication link quality. The output signal levels of at least one low noise amplifier (LNA) are monitored to identify the DC operating conditions for the LNA. Closed loop control of the DC biasing is adjusted based on a comparison between the monitored DC operating conditions and a reference signal. The output of the LNA is also coupled to a radio receiver section that is configured (e.g., SW or HW) to evaluate the link quality based on various criteria such as inter-modulation distortion, noise, interference, fading, etc. The reference signal that is used to control the DC biasing of the LNA is adjusted (periodically, continuously, or on demand) in response to the evaluated link quality. The dynamic biasing yields acceptable signal reception with low DC power consumption.
Abstract:
The present invention relates (with reference to FIG. 1) to an internal combustion engine in which a combustion chamber (12) can be connected to a reservoir (16) for storing compressed air. Gas flow control valve means (15) controls flow between the chamber (12) and reservoir (16) so that air pressurised in the chamber (12) can be relayed to charge the reservoir (16) and pressurised air can be delivered to the chamber (12) to drive piston (10). The chamber (12) is also used for combustion of fuel. The invention also relates to a valve mechanism for controlling the flow of pressurised air between the chamber (12) and reservoir (16), in which a balancing force is applied to the gas flow control valve (115) to cancel the force on the valve (115) arising from the pressure applied to the back face of the valve (115).

A second coupler couples the device to the appliance. A monitoring circuit is connected to the first coupler and the second coupler to monitor power supplied by the source to the appliance. A communications circuit also is provided. The monitoring circuit provides data based on the monitored power to the communications circuit for output to the first coupler. The communications circuit may include a receiver that receives a signal from the first coupler to control the monitoring circuit. The communications circuit also may include a transceiver that receives a signal from the first coupler to control the monitoring circuit and to transmit monitored power data.
