Title: Acquisition scheme for vibroseis marine sources
Filed: 2012-08-31
Abstract: Control mechanisms, computer software and methods for driving vibrational source arrays underwater. An incoherent acquisition scheme drives individual source elements simultaneously and incoherently while a coherent acquisition scheme drives high-frequency individual source elements simultaneously and incoherently and low-frequency individual source elements simultaneously and coherently. Thus, denser coverage and an increased energy input is achieved for the source arrays.

Title: Method and device for enviroment sensing
IPC: G01S15/931
Filed: 2013-02-19
Abstract: A parking aid for a motor vehicle 1 comprises at least two sensors 5. Each sensor 5 transmits and receives ultrasonic pulses. Initially all transmitters transmit simultaneously on different frequencies, sequentially or in groups (e.g. front and rear). When one or more receiver(s) receive echoes reflected by object 7, only the corresponding transmitter operates. This enables more effective tracking of object 7. Time of flight indicates range. A pair of sensors detects the objects direction. Every 10 or 20 measurement cycles, all transmitters transmit once. The sensor may have a damped oscillating (vibrating) membrane driven by a piezo-electric element.

Abstract: A method of unloading liquid from a reservoir comprising: introducing two amphoteric surfactants into the liquid in order to foam the liquid; and removing the foamed liquid from the reservoir. The first amphoteric surfactant is a C8-22 sultaine, a salt thereof, or mixture thereof. The second amphoteric surfactant is selected from a C8-22 betaine, a C8-22 propionate, salts thereof, or mixtures thereof. Also claimed are synergistic surfactant compositions comprising: a) 20-80% wt of a first amphoteric surfactant selected from a C8-22 sultaine, a salt thereof, or mixture thereof; and b) 20-80% wt of a second amphoteric surfactant selected from a C8-22 betaine, a C8-22 propionate, salts thereof, or mixtures thereof.

Title: Staple fibre cutting machine
Inventor: MCLUSKIE ALBERT
IPC: B26D1/36
Filed: 1980-05-24
Granted: 1983-08-25
Abstract: A machine for cutting a travelling tow of synthetic plastic filaments to produce staple fibers has a blade carrier from which cutting blades project and have their free ends secured to a concentric surrounding ring. The facing annular surfaces of ring and carrier are shaped to resemble portions of a hollow and of a solid sphere, respectively, and together define an annular cutting channel. A tow pressing ring is arranged skew to the axis of this channel, so that it enters into the channel at one side but is spaced from and defines with the inlet to the channel a gap at the opposite side. One or the other of the carrier and ring is positively rotated. When tow is fed through the gap into the channel it forms on the carrier one or more convolutions which are progressively pressed deeper into the channel by the pressing ring until they reach and are cut by the cutting blades.

Patent DE-3280143-D1 (DE)
Inventor: MEYER STANLEY A
IPC: F23D14/02
Filed: 1982-12-14
Granted: 1990-05-03
Abstract: A sustained controllable gas flame. The hydrogen generator utilized is that for separating gasses from water having impurities and other gasses entrapped therein. The gasses separated from the water comprises hydrogen, oxygen, and the non-combustible gasses, such as nitrogen. The nitrogen, oxygen and hydrogen are mixed as they are released in the process by the generator and collected as the mixture of gasses in the collection chamber of the generator. The method and system comprises a nozzle of a given configuration connected through a line to the uppermost region of the gas collection chamber of the hydrogen generator. The nitrogen reduces the velocity and temperature of the burning flame from that of the hydrogen/oxygen mixture. To further control the temperature and velocity of the burning gas mixture there is added to the collection chamber other non-burnable gasses. The configuration of the nozzle and its port opening is dependant on the mixture of gasses utilized and restricted thereby. An increase in the size of the flame requires additional port openings to prevent blowout. CROSS REFERENCE: The hydrogen/oxygen generator utilized in the present invention is that disclosed and claimed in my co-pending U.S. patent application, Serial Number: 302,807, filed: September 16, 1981, for: HYDROGEN GENERATOR SYSTEM. In that process for separating hydrogen and oxygen atoms from water having impurities, the water is passed between two plates of similar non-oxidizing metal. No electrolyte is added to the water. The one plate has placed thereon a positive potential and the other a negative potential from a very low amperage direct-current power source. The sub-atomic action of the direct current voltage on the non-electrolytic water causes the hydrogen and oxygen atoms to be separated ... and similarly other gasses entrapped in the water such as nitrogen. The contaminents in the water that are not released are forced to disassociate themselves and may be collected or utilized and disposed of in a known manner. The direct current acts as a static force on the water molecules; whereas the non-regulated rippling direct current acts as a dynamic force. Pulsating the direct current further enhances the release of the hydrogen and oxygen atoms from the water molecules.

Granted: 1987-02-05
Abstract: An introducing catheter for use with a pair of different diameter wire guides, the larger of which is a J-type wire guide, is provided in order to enlarge a tract to facilitate the passage of a drainage catheter through the tract. The introducing catheter includes an inwardly curved portion which lies between the distal and proximal ends of the catheter with the curved portion being located nearer to the distal end. The catheter also has a flexible tapered tip at its distal end and a lumen which decreases in area towards the distal end. The catheter further has a side port which is distally positioned from the curved portion and on the inward side of the curved portion so that when a J-type wire guide is advanced within the catheter from the proximal end, the wire guide will automatically emerge through the side port. The side port has an oval or elliptical shape with its major axis along the length of the tube. The catheter lumen has a diameter at the distal end which is substantially smaller than the minor axis diameter of the side port so that a wire guide having a substantially smaller external diameter than that of the J-type wire guide may be used as a guide for the catheter distal end. The introducing catheter is radiopaque, so that its position within a body can be monitored. The introducing catheter has a base portion at the proximal end for grasping and manipulating the catheter during a catheterization.
