Title: A servo operated stop valve installation
Inventor: PEDERSEN HANS NOERGAARD
IPC: F16K31/163
Filed: 1994-04-07
Abstract: A subterranean stop valve in a district heating system is laid out for servocontrolled operation from a nearby walkway cabinet, by hydraulic actuation of a double acting free piston block (8), which is displaceable with high power just as much as required for a full change-over of the valve (2). Just prior to the full change-over being reached it is automatically arranged that at the hydraulic return end of the piston the return flow (28) is shifted to now be forced (at 42) into a remote indicator (48), whereby a slide body (54) in the latter is changed over, affected by a high force immediately at the end of the full valve change-over. Hereby a robust and long-time durable change-over and indicator system is achievable.   <IMAGE>

Title: Saw blade mounting
Inventor: HUG ARNOLD
IPC: B23D61/12
Filed: 1996-01-23
Abstract: In a power hacksaw, especially a sword saw, having two saw blades (16, 17; 116), which are disposed such that they run to and fro in opposite directions and have at their lower longitudinal edge a row of teeth (22, 23) and on the opposite longitudinal side a saw blade back (26), the clamping end (25) has a U-shaped latch pocket (29) in the contour of the saw blade back (26). The latch pocket engages a to-and-fro running gear element. The strength of the saw blade clamping end is increased, whilst, at the same time, a predetermined breaking point is arranged by the fact that the saw blade has a region (30) which juts out, over the tooth side (22, 23). The region (30) serves as a counterweight, for vibration-damping purposes, as the saw blade (16; 116) runs to and fro. It also cooperates with a stop (30') to retain the blade if it breaks. <IMAGE>

Title: Satellite Commmunications Terminal Location Method
Inventor: WYRWAS RICHARD
IPC: H04W24/00
Filed: 1997-03-25
Abstract: In a satellite communications system, where a satellite 10 provides a plurality of radio beams 30, and where distance and/or angle measurement from a satellite 10 or satellites 10 enables the position of the user terminal 44, on the surface of the earth 14, to be measured to within an uncertainty of being in one out of a possible plurality of positions 142. Which of those positions is actually occupied by the user terminal 44 is determined by measuring the strength of a signal in each of the beams covering the positions. When the plurality of positions falls within a single beam 30A, which out of the plurality of possible positions 142 is actually occupied by the user terminal 44 is determined by assessing the quality of signals received from those other, adjacent, overlapping beams 30B - 30G which surround the beam 30A in which the user terminal 44 is believed to be.

Title: Selecting optimum seismic data processing sequences and parameters
Inventor: POGGIAGLIOLMI ELIO
IPC: G01V1/28
Filed: 1997-05-28
Abstract: Determining an optimum processing sequence by calculation of processing sequence sensitivity and error. A reference seismic processing sequence and a series of test seismic processing sequences are applied to input raw gathers to obtain reference and test seismic output data respectively. The normalised differences between the test and the reference data are calculated on a sample by sample basis in the time domain and displayed on plots indicating the sensitivity for each processing step (fig. 1). Linear regression is performed for each CMP gather to obtain the stack and the zero offset calculated for each time index and the difference is recorded. The normalised differences between the error for the test and the reference sequences are calculated and displayed (fig. 2). If necessary, any processing step is rejected and the reference processing sequence revised. A method of parameter optimisation based on a single well or multi-well wavelet analysis is described.

Title: Multicolor organic light emitting devices
Inventor: SAPOCHAK LINDA
IPC: H01L27/15
Filed: 1995-12-06
Abstract: A multicolor organic light emitting device employs vertically stacked layers of double heterostructure devices which are fabricated from organic compounds. The vertical stacked structure is formed on a glass base having a transparent coating of ITO or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices, each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack. This constitutes the device emitting red light on the top with the device having the shortest wavelength, namely, the device emitting blue light, on the bottom of the stack. Located between the red and blue device structures is the green device structure . The devices are configured as stacked to provide a staircase profile whereby each device is separated from the other by a thin transparent conductive contact layer to enable light emanating from each of the devices to pass through the semitransparent contacts and through the lower device structures while further enabling each of the devices to receive a selective bias.

[Also in Division H3] In a D.C. motor, commutation is effected by means of a switching transistor in series with each stator winding, the switching transistors being controlled by regenerative two-state circuits, which are in turn controlled in dependence on the angular position of the rotor. Photo-electric commutation control.-Figs. 1, 2a show a D.C. motor for a dental drill operating at over 100,000 r.p.m. and comprising an even number of stator windings 22, 23 wound on a laminated or ferrite core and a permanent magnet or D.C.-energized rotor 29. The rotor is provided with a lamp 5 within a sleeve having a slot 4 which allows photo-diodes 6 ... 9 to be successively illuminated. Each pair of stator windings 22, 23 is supplied with current from rectifiers 20, 21 under control of switching transistors 70. Two-state circuits are provided comprising transistors 10, 14 having regenerative feed-back via resistor 19. Transistor 10 is normally conductive so that transistors 14, 17 are non-conductive. When one of the photodiodes 6 ... 9 is illuminated, the conductive state of transistors 10, 14 becomes reversed, so that the appropriate transistor 17 becomes conductive, energizing the appropriate stator winding in one direction. Two switching transistors 17 are provided for each stator winding so that the direction of current is reversed when the rotor has travelled 180 degrees. The slotted sleeve may be replaced by a reflector mounted at 45 degrees to the rotor and reflecting light successively to the photodiodes.
