Title: Improvements in or relating to regulating devices
IPC: G05B11/01
Filed: 1927-12-19
Abstract: 282,676. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Dec. 24, 1926, [Convention date]. Regulation, automatic.-A roller a running on a surface such as that of a drum b is rotated about the axis c<1> of its support by the arm e of a measuring device such as a voltmeter f. The resulting lateral motion may be employed to actuate a valve, electrical resistance or other regulating device through the supporting arm d. The drum may be formed of insulating and conducting material, divided, for example, as shown in Fig. 4, and connected through the roller with a resistance g in the field circuit of an alternator the voltage of which controls the arm e. A strip of material of low conductivity may be inserted between drum sections to reduce sparking or an insulated conducting strip or strips may be connected to a portion or portions of the resistance to control it in sections. The drum may be non- cvlindrical and a rise and fall of the roller may operate the regulator, the contour of the drum being varied across its width to cause varied reciprocation of the roller when turned. The arm e may be actuated by a pressure gauge or a bimetallic strip for controlling pressure or temperature respectively. The Specification mentions the application of the device to electrically driven log-grinding machinery in which the capacity of the driving machine is regulated by altering the tool pressure.

Abstract: 1,004,584. Centrifugal pulverizers. BATH IRON WORKS CORPORATION. Aug. 22, 1964, No. 34439/64. Heading B2A. A rotatable impeller assembly, for a centrifugal pulverizer suitable for reducing particles of abrasive materials, e.g. silicon carbide, comprises upper and lower horizontally opposed discs 12, 14, Fig. 2, with radially disposed vanes 20 secured between them, each of the vanes having a main radial portion 21, Fig. 4, and cupped arms 25, 26, 27 extending circumferentially in the direction of rotation to form pockets ; the extremity of each of the arms has a lateral notch 25n, 26n, 27n between the upper and lower discs to provide passage for the particles of material. As described, particles are fed via a stationary tube 18 into a hub cup 19 set in a hub 16, so that, in operation, the particles fill up the corners and form a protective, inclined surface for following particles. Each vane 20 has a fourth arm 28 extending opposite to the direction of rotation of the impeller assembly and the first arm 25, and notched at 28n to direct particles ejected from the cup 19 into the pockets formed by the arms 25-27. These fill with lodged particles, so that following particles are delivered via the notches 25n-27n. Thus the material in the pockets protects the vane and disc material from excessive wear. The extremity of each arm is at an angle of 90 degrees to the inward portion which in turn is angled at about 40 degrees to the radial portion 21.

Filed: 1935-12-14
Abstract: 449,230. Photo-electric cells. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Dec. 14, 1935, No. 34737. Convention date, March 14. Drawings to Specification. [Class 39 (i)] An electrode having photo-electric properties is manufactured in a tube by decomposing partly a layer of oxidized photo-electric metal, such as caesium, the layer being utilized as an electrode in a discharge through inert gas, and the oxygen set free being taken up by a getter, such as barium or calcium. The oxidized layer may be produced by introducing oxygen into the tube which contains the photo-electric metal, or the photo-electric metal may be vaporized onto a silver oxide layer. The getter pellet may comprise barium chromate and zirconium or copper-plated barium which will not become operative until after oxidation of the layer, when the pellet is heated. The discharge decomposing the layer may be maintained in argon at a pressure of 0À1 mm. and this argon may remain as the filling of the completed cell, which may, however, be given another filling or be evacuated. The electrode has secondary electron-emitting properties and may be used as a secondary electron emitter.

Title: A method of soldering and a device for carrying out the method
IPC: B23K1/19
Filed: 1970-07-20
Abstract: 1280770 Soldering BOUSSOIS SOUCHON NEUVESEL 20 July 1970 [24 July 1969] 35005/70 Heading B3R A method of forming a soldered joint between 'the flange of a U-section lead strip and the mar- 'gin of a glass plate which has previously been metalized with tin comprises pressing the flange against the glass plate under controlled pressure and heating to a temperature sufficient to melt the tin but insufficient to modify the crystal structure of the lead, the pressure being maintained while cooling takes place until the tin has set. The method is described with reference to joining the flanges 2a, 2b of a U-section spacing strip 2 to the two glass panes 1a, 1b of a doubleglazing unit. The glass is initially metallized with a layer of copper 40, and the tin layer 50 then deposited thereon. The lead strip is preferably also tinned at 60. Flux may be applied to the tinned areas and the soldering operation produces fillets 2e, 2d. Apparatus for carrying out the soldering operation comprises a table 20 on which the glass plate 1a is laid, a heating block 5 mounted on a vertically adjustable beam 3 adjacent the edge of the table, the heating block having a soldering lip 101 adapted to overlie the flange 2a of the strip 2, and a clamping plate 6 with elastic clamping member 9. The clamping plate is vertically adjustable by cams 8 to clamp the flange 2a and glass plate 1a between the heating lip 101 and the clamping member 9 at predetermined adjustable pressure. The heating block has a duct 104 for heating fluid (or alternatively electrical resistance heating elements) and passages for cooling fluid e.g. air, to be directed through the lip 101 at the web of the strip 2. Embodiments are described for soldering the upper and lower flanges simultaneously and soldering devices may also be arranged at right angles in order to solder two sides of a double-pane unit simultaneously.

Title: Measuring apparatus
Inventor: MEIER JOHANN
IPC: G01B11/00
Filed: 1969-07-11
Abstract: 1,263,608. Measuring linear dimensions. J. MEIER. July 11, 1969 [July 15, 1968], No.35059/69. Heading G1M. A vertically movable sensor 18, Fig.1, carries a transparent scale 20 whose movements during gauging are projected by a lamp 26, condenser 27, projection lens or objective 28 and mirrors 29, 30, 31, on to a screen 35 which may be read by reflection from an adjustable hinged mirror 36. The mirror 30 may be moved about its horizontal axis to adjust the zero point on the screen 35. The screen 35, Fig.5, comprises four scales, the scale 60 showing the digit markings e.g. 23 of the projected scale 20, the scale 61 showing the graduation lines 0-10 between digits on the projected scale 20, a scale 62 which is only displaceable for the distance between two graduations on the scale 61, and a micrometer type scale 63 which rotates 100 divisions for every full movement of the scale 62. Thus a vertical movement of the sensor 18 is transmitted to the scale 20 and projected and magnified on to the screen 35 where it is finely gauged and shows 23À604 mm. If a finer calibration is drawn on the scale 20 then the second expanded scale 61 is superfluous see Fig.10 (not shown) and the displaceable scale (101) corresponding to scale 62 need only be of short length but still coupled to a moving scale (102). In Fig.11 (not shown) scales calibrated differently in millimeter fractions and thousandths of inches are used, and in Figs.8 and 9 (not shown) a scale (20") is marked with an opaque patch (81) which co-operates to shut off light to photo-cells (91), (92) mounted in an adjustable measuring head (90). The distance between the cells is adjusted to the permissible tolerance to be measured so that if lengths within such tolerances are measured then only one of the cells will be illuminated through a light permeable portion (82) of the scale (20") and the other cell would remain dark, being obscured by the opaque portion (81). As the cells are so selectively energized, then circuits connected to them indicate the acceptability or otherwise of the length being gauged. In Fig.6, the sensor 18 operates to pivot a beam carrying a scale 20<SP>1</SP>, about a fulcrum 73 thus magnifying the movement of the sensor. By turning the sensor about 180 degrees a pin 74 may be engaged instead of the pin 75 to give a different lever arm ratio, but the pins themselves are adjustable by means of a screw 78.
