Title: Improvements in the Electro-deposition of Copper.
Inventor: COWPER-COLES SHERARD OSBORN
IPC: C25D5/04
Filed: 1917-01-18
Abstract: 112,516. Coles, S. O. Cowper-. Jan. 18, 1917. Electrodes; cells; electrolytes, circulating and agitating. - In the deposition of copper, a cathode rotating on a vertical axis is caused to reciprocate vertically, one complete reciprocation taking place every two or three revolutions. The electrolyte is kept in motion. The peripheral speed of the cathode may be 50 ft. per minute. In an apparatus for making tubes, cathode mandrels h, Fig. 2, are arranged in a row between rows of anodes f and are driven by a single belt o and pulleys o<1> splined on the mandrel shafts. Fast collars k on the shafts rest on eccentric cams l on a horizontal shaft m, which drives the belt o through bevel gear. Electrolyte may be squirted at right-angles or in a contrary direction to the motion of the cathode, or may be driven by jets of compressed air from a perforated pipe d. In apparatus for making sheets, a bell-shaped cathode h, Fig. 4, in an annular vat a is mounted on a vertical shaft i reciprocated by a bell-crank r, link s, and crank t. The cathode may be grooved to facilitate removal. Flat anode bars f are arranged in a circle. A pipe x supplies compressed air. Specification 27385/07 is referred to.

Title: High Voltage Circuit Breaker with Means for Inserting Resistors During Closing.
IPC: H01H9/54
Filed: 1968-01-08
Abstract: 1,151,831. Arcing preventing in switches. GENERAL ELECTRIC CO. 8 Jan., 1968 [24 Feb., 1967], No. 996/68. Heading H1N. A resistor 30 is connected across each pair of contacts 12, 14 of a multi-break circuit-breaker by means of a triggered spark gap 32 during closing. The vacuum gaps 32 are of the kind comprising main electrodes 46, 48a and auxiliary electrodes 58, 60 of titanium with absorbed hydrogen; when a pulse from a source 70 is applied to electrodes 58, 60 an arc is struck between them which feeds plasma to the main gap 50. An arc then strikes across the main gap 50 to connect the resistor 30 across main contacts 12, 14. The source 70 is operated by an S.C.R. which is rendered conductive by light transmitted from a lamp 75 by fibre optics 73. The lamp 75 is energized, after contacts 85 are closed by initial movement of main contacts 14, by a timing circuit 80 so that all sources 70 provide triggering pulses within a few microseconds of the voltage zero. Shortly after 85 another contact 92 closes and an oscillator 90 provides repetitive pulses to maintain the arc across gap 50 until contacts 12, 14 are fully closed when a cam switch 86 disconnects the lamp. The oscillator is omitted if gap 32 is of the low pressure gas filled type which maintains the arc after current zero. Both electrodes of the gap 50 may be triggered (Fig. 1a, not shown). In a modification (Fig. 2, not shown) the resistor and spark gap are connected between the fixed contact 12 and an auxiliary contact (100) thus providing an isolating gap (102) in the open position. The resistors may be connected across the main contacts during opening as well by means of auxiliary switches (110) (Fig. 3, not shown), or by making one contact of the spark gaps movable to engage the other when the main contacts close (Fig. 4, not shown).

Title: High mix printed circuit assembly technique
Inventor: DAVIS THOMAS C
IPC: H05K13/08
Filed: 1997-03-20
Abstract: Components are assembled on printed circuit boards in groups to be manufactured together, and to minimise the overall set up time, the components are arranged in the groups in dependence on maximising board volume added per component. In a method of assembling components on a board using machines having a plurality of banks, a first cell of components is chosen which are installed on a high volume board for continuous installation from at least one of the banks. A setup of components is done in a different cell without having to interrupt the continuous installation of the components of the first cell. The installation of components is activated from the second cell after the setup is completed in order to install components on a lesser volume board. <IMAGE>

Inventor: DAKIN WAYNE RAY
IPC: G11B19/24
Filed: 1986-07-03
Abstract: Method and apparatus for recovering information at a substantially constant rate from a rotable information storage disc (110). The information is stored on the disc (110) in a plurality of substantially circular and concentrically arranged information tracks, with a substantially uniform recording density, and it is recovered by controllably rotating the disc, relative to a transducer (128) at an angular velocity substantially inversely proportional to the radius of the corresponding track. The apparatus includes a coarse speed control potentiometer (130) for producing a measure of the radius of the particular information track from which information is being recovered, and fine speed control means (136) for comparing the relative phase angles of a periodic signal in the recovered information and a periodic reference signal and for producing a fine speed control signal proportional to the phase difference. The measure of radius and the fine speed control signal are summed together and coupled to a voltage-controlled oscillator (132) to produce a composite speed control signal, which is coupled to a servo (134) to rotate the disc (110) at a corresponding angular velocity.

Title: Cell encapsulating method and apparatus
Inventor: AEBISCHER PATRICK
IPC: A61K35/13
Filed: 1996-04-03
Abstract: Methods and systems are disclosed for encapsulating viable cells which produce biologically-active factors. The cells are encapsulated within a semipermeable, polymeric membrane by co-extruding an aqueous cell suspension and a polymeric solution through a common port to form a tubular extrudate having a polymeric outer coating which encapsulates the cell suspension. For example, the cell suspension and the polymeric solution can be extruded through a common extrusion port having at least two concentric bores, such that the cell suspension is extruded through the inner bore and the polymeric solution is extruded through the outer bore. The polymeric solution coagulates to form an outer coating. As the outer coating is formed, the ends of the tubular extrudate can be sealed to form a cell capsule. In one embodiment, the tubular extrudate is sealed at intervals to define separate cell compartments connected by polymeric links.

Title: Concentricity machining device and method using vision system
Inventor: KIN GENTETSU
IPC: G01B11/27
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To dispense with the use of a tailstock and a circular bar and to enhance the machining precision of a product by directly fixing the outer diameter of the product to a chuck. SOLUTION: A servomotor 500 is provided with a chuck 510 for holding a product 520. The section of the mounted product 520 is image-picked up by a camera 550, and the inside diameter is displayed on the basis of the center of the section on a vision system 570. The product 520 is rotated at a preset rotating angle by the servomotor 500. The rotating angle is optionally settable, and when 8 is set, for example, the rotating angle corresponds to the value of 360 deg. equally divided to 8. The section of the rotated product 520 is image- picked up by the camera 550 and displayed on the vision system 570. When the section photographing and inside diameter display are repeated in the set rotating angle unit, the track of the inside diameter of the product 520 is circularly displayed, and the diameter of the circle forms the concentricity.  Since the outer diameter is directly fixed to the chuck 510, the tolerance in the use of a tailstock and a cylindrical bar can be eliminated.
