Title: Improved spreader for applying bonding compounds
Inventor: LIBERMAN ISAK
IPC: E04F21/06
Filed: 1993-07-28
Abstract: An improved tool for spreading bonding compound, or the like, on planar surfaces which, in a first embodiment, includes a contoured surface (15, 16) having two end tip portions (40) and a midportion (20) contained in a plane spaced between the end tip portions. The tool includes a back (64) which gives structural integrity to the tool, and a flexible outer edge connected to the application face (15). In use, the bonding compound is applied to the planar surface, and the projecting flexible outer edge of the application face is forced against the wall and pulled along to obtain a flat surface to spread the bonding compound evenly and smoothly over the planar surface. The flexible outer edge can be removable and replaceable for adjusting to varying surfaces and for easy maintenance.

Title: Single Diaphragm Second Order Differential Microphone Assembly
Inventor: BARTLETT CHARLES S
IPC: H04R1/38
Filed: 1995-02-23
Abstract: A second-order differential (SOD) microphone includes a first-order differential (FOD) microphone element installed in a housing. A pair of front sound conduits extend from respective ports to a chamber on the front side of the microphone diaphragm, and a pair of rear sound conduits extend from respective ports to a chamber on the rear side of the microphone diaphragm. The two front ports and the two rear ports are all substantially collinear along a minor axis, with the rear ports intermediate the front ports or the front ports intermediate the rear ports. The respective acoustic transfer functions from each port to the microphone diaphragm are equivalent. The microphone response is approximately proportional to the second spatial derivative, along the minor axis, of a sampled acoustic pressure field.

Title: Method for steering an agricultural machine and an agricultural machine
Inventor: MUTSAERS FRANCISCUS HUBERTUS J
IPC: A01B69/00
Filed: 1994-05-11
Abstract: The invention relates to a method for steering an agricultural machine and to an agricultural machine. Especially when treating rows of crops (14, 15) it is important that, for the cultivation operation concerned, a differentiation is made between the crops located in the rows and that which is located between them. For this reason, accurate steering of the agricultural machine has to follow a series of desired positions (15, 18). The driver lines up the agricultural machine with said series with the aid of a marker (25). Furthermore, according to the invention, actual direction of travel of the agricultural machine and not just actual position of the agricultural machine is involved in the determination of the steering corrections to be made.

Abstract: A document retrieval and display system retrieves source documents in different languages from servers linked by a communication network, translates the retrieved source documents as necessary, stores the translated documents, and displays the source documents and translated documents at a client device connected to the communication network. The translation process is activated automatically by a control module, and is carried out by a machine translation module. The control module decides when a translation is necessary, selects whether to display the source document or a translated document at the client device, and determines when the source document has been updated and must be retranslated.

Title: Steerable rotary drilling systems
Inventor: BARR JOHN D
IPC: E21B7/06
Filed: 1996-02-23
Abstract: A modulated bias unit, for use in a steerable rotary drilling system, comprises a number of hydraulic actuators spaced apart around the periphery of the unit, each having a movable thrust member which is hydraulically displaceable outwardly for engagement with the formation of the borehole, and a control valve operable to bring the actuators alternately in succession into and out of communication with a source of fluid under pressure, as the bias unit rotates. The fluid pressure supplied to each actuator may thus be modulated in synchronism with rotation of the drill bit, and in selected phase relation thereto, so that each movable thrust member is displaced outwardly at the same rotational position of the bias unit so as to apply a lateral bias to the unit for the purposes of steering an associated drill bit. To enable the biassing action to be neutralised or reduced there is provided an auxiliary shut-off valve in series with the control valve, which is operable to prevent the control valve from passing the maximum supply of fluid under pressure to the hydraulic actuators.

Patent CA-2174437-A1 (CA)
Inventor: ZAVISLAN JAMES M
IPC: G02B27/44
Filed: 1994-10-14
Abstract: A miniature scan engine module (28) for bar code reading and data collection systems utilizes a light source (40) and a light collector (42) flexurally supported on a platform (54) which reciprocates on pivots defined by flexures (46 and 48). The light received from the code, as it is scanned, is collected along an optical collector (42) having surface area approximately equal to the surface area of one side of the scan engine. The optical collector (42) faces the bar code and pivots with the scanning beam source (40), a laser diode. A pair of diffraction gratings (66 and 67) along a surface of the optical collector (42) which faces away from the code directs the incoming light so that it propagates internally in a substrate (65) within the body of the collector in which the gratings (66 and 67) are embedded, i.e. in the optic itself to photodetectors (68 and 73) via reflective and light concentrating surfaces over the photodetector (68 and 73). Efficient light collection capability, without the need for special optics such as lenses and collection mirrors, enables the scan engine to be configured so that it occupies a miniature volume. A data collection system, in the form of a portable terminal, has a housing (12) which provides the handle for a scanning accessory which is the scan engine module.

Title: Water for medical treatment, production method thereof, and dialysis apparatus using water for medical treatment as dialysis liquid
Inventor: MORISAWA SHINKATSU
IPC: A61M1/16
Filed: 1996-07-04
Abstract: A main feature of the present invention is to provide water for medical treatment that can abolish the Superoxide Anion Radical (SAR) which may trigger various diseases. Raw water including at least natrium, kalium, magnesium and calcium ions is supplied to a cathode chamber and an anode chamber. A current within the range of 0.16 mA/cm2 ~ 3.2 mA/cm2 is applied per two electrodes and one diaphragm for 0.5 seconds ~ 5 seconds across a cathode electrode and an anode electrode to electrolyze the raw water. By this method, water for medical treatment is produced that has an oxidation-reduction potential value within the range of -150 mV ~ 0 mV measured using a platinum electrode. The water for medical treatment can remove the SAR, which may become the cause of various diseases, from the blood of a patient.
