Inventor: NORMANN LINDA M
IPC: G06F17/50
Filed: 1993-04-28
Abstract: A method and apparatus for designing and editing a distribution system for a building is disclosed. Elements of such distribution systems and requirements of relevant standard are stored in a computer's memory (20-23,33). Building parameters (2) are entered into a computer manually (1). The users identify the standard to be followed and the element to be optimized. The system divides the building into sections (4) as appropriate to the user identified standard. The system then computes layout needed to comply with the selected standard. The layout is routed (18-33) and sized to avoid building structural members, yet the elements of the layout are optimized for size and length. The apparatus prints out a hard copy of the design layout which can include an elements listing (120-129) needed to complete the system. The design layout as well as the building parameters can be edited. The edited layout is checked for compliance with the identified standard as well as avoidance of building parameters.

Abstract: The flat and circular type knitting machines as known hereinbefore are characterized by the knitting needles moving linearly, being arranged in a straight line and held on a flat needle bed or arranged in a circle on a rotating cylinder, actuated by a cam, a disk or an actuator. The knitting machine of the present invention introduces a new form, a new manner of moving and a new bed of a knitting needle. According to the present invention there is provided a knitting machine comprised of a plurality of knitting needles, each of them having a curved profile and by its form representing an arc of a circle having its centre in a needle axle, which corresponds to a needle bed of the knitting machines of the previous constitution, around which it can make an angular motion in the loop forming process. Therefore this knitting needle is called a radial knitting needle (RKN). To each RKN is associated one actuator, in such a way that the RKN is mechanically attached to a rotor of an actuator at a distance from the centre of rotation equal to the radius of the RKN, whereby the actuators are the rotary direct current motors with a common magnetic flux of stator of all the actuators and the rotors shaped as a section of a circle, on which arc is firmly supported the RKN. In order to exactly position the rotor, i.e., the RKN, there is provided a position controller capable of positioning the actuator to any position according to a predetermined knitting plan, within the central angle of the RKN. The knitting machine of the present invention opens new opportunities for creative knitting designs, especially fully fashioned knitted fabric, increases the speed of knitting, and reduces manufacturing costs.

Title: Digital sensor cassette for mammography
Inventor: SAYAG MICHEL
IPC: A61B6/00
Filed: 1995-10-26
Abstract: A CCD-scintillator x-ray image sensor  (18)  has a high sensitivity at room temperature and a low profile, enabling the  use  of  the  x-ray  image  sensor  in  most  modern mammography x-ray machines. A cassette 10 that encloses the CCD-based x-ray image sensor has the approximate dimensions of 10.5 x 7.7 x 0.6 inches,  and is thus form and fit compatible  with  conventional film-based  cassettes.  An electronic interface to the cassette requires but a single cable (24) and a standard connector (22) for connection to a CCD sensor electronics unit. The CCD sensor electronics unit interfaces to a computer,  such as a conventional personal computer or workstation, having a relatively high resolution display and a provision for digitally recording high-resolution electronic images. The high sensitivity at ambient   (room)   temperature  results  from  an  x-ray scintillator screen (18c) that is coupled to the CCD image sensor (18a) via a bias cut fiber optic faceplate (18b). The CCD image sensor has very low dark current density, high responsivity to the green fluorescence of the screen, and multiple output ports for minimizing the time required for readout and for minimizing the noise bandwidth at the output.

Title: Electrochemical surface analysis using gel electrolyte
Inventor: WHITE JOHN T
IPC: G01N27/42
Filed: 1995-10-27
Abstract: Electrochemical surface analysis using a deoxygenated gel electrolyte provides advantages over a liquid electrolyte in processes such as sequential electrochemical reduction analysis. In sequential electrochemical reduction analysis, a solderable portion of an electronic component or circuit board to be tested is placed in contact with a deoxygenated gel electrolyte such as a borate buffer solution having a gelling agent. The gel electrolyte prevents capillary attraction up or along a lead of the component so that the power source cathode lead does not contact the electrolyte and electrochemical analysis can be localized to the area of interest, such as the portion of the component lead to be soldered. Interfering effects of atmospheric oxygen are minimized for deaerated gel electrolytes because convection mixing is practically absent and diffusion is generally a very slow process in a gel. For a gel electrolyte saturated with inert gas and including an oxygen scavenger, brief exposure to oxygen as test specimens are changed does not affect the electrochemical analysis. In some cases, it is be possible to perform electrochemical analysis in ambient atmosphere rather than in an inert gas as generally required by the prior art.

Abstract: A film cartridge storage apparatus for storing a plurality of film cartridges stacked one on another. The stored film cartridges are extracted from the apparatus one after another from the lowermost cartridge in association with a pivotal member of an individual feed mechanism having a first arm portion and a second arm portion. The first arm portion of the pivotal member pivotable between a first area and a second are functions to hold the lowermost film cartridge in the first area and also to feed the lowermost film cartridge in the second area. The second arm portion of the pivotal member functions to allow a film cartridge to fall toward the first arm portion in the first area and also to prevent a film cartridge from falling toward the first arm portion in the second area. An elastic escape means is provided for avoiding mutual interference between a film cartridge contacting the second arm portion and a pivotal locus of the second arm portion in the course of the pivotal movement of the second arm portion from the first area to the second area.

Abstract: The flexible filter element (12) of the filter (10) is pleated in a zig-zag-shaped configuration and has its longitudinal edges (24) connected to support elements (26). Each of the support elements (26) comprises a plurality of support members (40) arranged beside one another and being interconnected by a continuous flange (28). The support elements (26) as well as the rest of the filter element (12) are made of a plastic material.
