Abstract: A power driven pipe threading machine is provided with a coolant system by which an oil free, glycol based coolant is dispensed onto the workpiece during thread cutting in the area thereof adjacent a thread cutting die at a rate which provides for the coolant to completely evaporate and for the workpiece to be cooled to a temperature which provides a good quality thread.          The coolant is pumped from a reservoir to a coolant outlet on the die head of the machine and through a needle valve by which the discharge rate is adjustable, and a torque responsive shut-off valve is associated with the die head for controlling the flow of coolant from the reservoir to the needle valve and coolant outlet in response to initial threading engagement between the workpiece and cutting dies on the die head.

Title: Process for the preparation of recombinant proteins in e.coli by high cell density fermentation
Inventor: PLUCKTHUN ANDREAS
IPC: C12N15/09
Filed: 1996-11-28
Granted: 2005-07-26
Abstract: The invention relates to a fed-batch fermentation process which uses special E. coli host/vector systems for the purpose of efficiently forming recombinant proteins, in particular recombinant antibody molecules, preferably antibody fragments such as miniantibodies. Under the given conditions, the E. coli cells are able to grow at a maximum specific growth rate up to very high cell densities. After the recombinant product formation has been switched on, it is only the formed product which restricts growth; there is no growth restriction due to substrates or metabolic by-products. High space-time yields of recombinant proteins can be achieved in this manner.

Granted: 2003-10-28
Abstract: A Vehicle Acceleration and Attitude Sensor is provided, having use as a vehicle collision sensor for activation of air bags and the like, and as well for detecting within off road vehicles an unsafe attitude of the vehicle. A compressible carrier medium of light or other wave energy, such as translucent foam, is coupled with a light or other wave energy source and a receiver. An inertial mass, which may consist of the carrier medium itself, is in contact with the carrier medium and operates to compress the carrier medium when the apparatus is either accelerated or tilted beyond a predetermined amount. A signal coupler and processor are associated with the energy source and receiver. The apparatus operates on the principle whereby compression of a scattering medium or an integrating cavity, within the region surrounding a light or other wave energy source, will increase the intensity of the wave energy. This increased intensity is translated into a measurement of the acceleration or tilt experienced by the sensor.

Granted: 2009-12-29
Abstract: A method and system for determining the airflow through an air preconditioning module having a sensible and/or latent energy transfer matrix having a pre- established relationship between airflow and pressure drop. The air preconditioning module processes an inlet air stream so that it becomes a uniformly distributed (and preferably substantially laminar) outlet air stream leaving the energy transfer matrix of the preconditioning module. The pressure differential between the inlet air stream and the outlet air stream is determined and translated into an airflow value based on the pre-established relationship between airflow and pressure drop through the energy transfer matrix of the air preconditioning module.

Title: Communications method, communications system, communications device and server
Inventor: TSUKUI MINORU
IPC: H04N1/42

Granted: 2007-12-11
Abstract: A communications method, communications system, communications device, and server which confirm performance information of a receiver communications device without negotiating with the receiver communications device before sending data, and sends an image most suited to receiving capability of the receiver communications device. The sender reads out performance information of the receiver communications device stored typically in a server before sending data, and sends data after converting the format of data to be sent based on the performance information. The communications device communicates with the server and sends data in the form of electronic mail and TCP/IP communications. Since, image data is sent after converting its format to that best matched receiving capability of the receiver communications device, the receiver communications device can receive image data best suited to its performance.

Abstract: An optical device (300) comprises a multilayer structure, formed by wafer bonding, incorporating in sequence a silicon dioxide layer (304), a buried silicide layer (306), a contact layer (308) and a silicon surface layer (310). The surface layer (310) is selectively etched to form an exposed rib (312). An upper surface of the rib (312) is doped to form an elongate electrode (314) therealong. The surface layer (310) is selectively etched to the contact layer (308) in regions remote from the rib (312) to form via channels (316a, 316b) for making electrical connection to the contact layer (308). The rib (312) forms a waveguide along which radiation propagates. When the electrode (314) is biased relative to the contact layer (308), charge carriers are injected into the rib (312) and induce refractive index changes in a central region (324) thereof where most of the radiation propagates along the rib (312). The silicide layer (306) provides an efficient current conduction path for injecting the carriers, thereby providing enhanced device operating bandwidth and reduced power dissipation.

Abstract: A communication DMA device having temporary storage for temporarily storing data to be transferred and an output for outputting several bits of data simultaneously is disclosed. The DMA device also has a register for storing information indicating an area of the memory in which data to be transmitted is stored, the capacity of the data to be transmitted, and an indication of the start of communication. A bus switching request requests the CPU to release the data bus, allowing the data, having a prescribed bit width, to be read from memory. The switching request circuit immediately reconnects the data bus to the CPU after termination of the data transfer. Based on the information stored in the register means, the data read from memory via the data bus is temporarily stored in a temporary storage circuit. The temporarily stored data is divided into several units, such as 8 bit units, which are output serially via the communication circuit.  The communication DMA device frees the CPU from the data bus and performs communication control and transmission of data, thereby reducing CPU load and also allowing high-speed data transfer.
