Title: Method of filling a porous structure
IPC: H01M4/29
Filed: 1959-09-01
Abstract: 917,291. Electrolyte processes; electric batteries. KANDLER, L. Sept. 1, 1959 [Sept. 3, 1958], No. 29867/59. Classes 41 and 53. A metal oxide or hydroxide is introduced into a porous, electrically conductive structure by electrolysing, with the structure as cathode, an acid electrolyte containing ions of the metal of which the oxide or hydroxide is to be produced, and reducible ions with a redox potential more positive than the discharge potential of the metal ions. The reducible ions may be nitrate, chlorate or permanganate. Electrodes for primary cells and accumulators of the alkaline-electrolyte type may be so prepared; in examples, a porous sintered nickel electrode was made the cathode in an aqueous acid solution of nickel nitrate with a nickel anode, divalent nickel hydroxide being deposited, the electrode then being made the anode in an alkaline solution to oxidize the hydroxide to the trivalent hydroxide; and a sintered nickel or iron electrode was made the cathode in an acid solution of cadmium nitrate with a cadmium anode, cadmium hydroxide being deposited, the electrode then being made the cathode in an alkaline electrolyte to reduce the hydroxide to metal.

Title: Wind shield cleaner
IPC: B60S1/34
Filed: 1924-12-13
Abstract: 226,535. Martin, L. J. H. Dec. 17, 1923, [Convention date]. Windows and the like, cleaning.-Apparatus in which a squeegee is moved over the screen by a continuously-driven endless cable or chain comprises a channel-shaped plate 1 fixed by lugs 3 to the upper part of the windscreen frame 4 and having at its ends spindles 20, 21 carrying pulleys 18, 19. An I-shaped bar 5 is fixed centrally of the plate 1 and ends near the spindles 20, 21, thus forming an endless guide 8, 9 for a carriage 6 having rollers 7 and carrying on a pivot pin 11 a resilient arm 12 having pivoted to it the squeegee 14. A stud 16 on the carriage is secured to the endless cable 17 passing over the pulleys 18, 19, the carriage being semicircular in shape so as to pass round the curved ends 1<b> of the plate 1. The wiper is in contact with the glass 2 only when the carriage 6 is in the part 8 of the guide, and this part is shaped so as to give a slight tilt to the carriage to press the wiper on the glass. In use the arm 12 abuts against a pin 15 on the carriage, due to the frictional resistance of the squeegee, but it can be swung into a horizontal position when not required. The pulley 18 is driven by a belt 22 from a pulley 23 mounted on a support 24 carrying a bayonet socket 25 taking a plug 27 on a rotatable rod 28. A spring 31 forces a square part 28<a> of the rod 28 into engagement with a slot 30 in the pulley 23, and fixed to the rod is a, flexible shaft 29 driven from the vehicle engine. In a modification, Fig. 6, the pulley 18 is driven, by a roller 39 on a shaft 38 having a square part 38a slidable in the support 24 and driven from the flexible shaft by pinions 42, 41. The pulley is pressed towards the roller by a spring 40, and by altering the distance of the roller from the shaft 20 the speed of the pulley may be varied. To stop the wiper the roller 39 is wholly removed from the pulley 18, the pulley being bevelled to allow the roller to be returned. The speed regulating device may be fitted between the rotating part of the vehicle engine and the flexible shaft 29. The guide 8, 9 may be arranged at the lower edge of the screen, and the device may be mounted on screens of the sharp front or V-shaped type, the guide being shaped to correspond with the edge of the screen and having rollers at the points where the direction of the cable 17 is changed.

Title: Roll froming heads for forming mills
IPC: F16H57/023
Filed: 1969-06-13
Abstract: 1,221,175. Skelping tubes. YODER CO. 13 June, 1969 [13 June, 1968], No. 30072/69. Heading B3E. [Also in Division F2] A roll forming head comprises top and bottom roller die shafts 10 and 11 journalled between inboard and outboard stands 14 and 15, means 43-46 to raise and lower the top shaft 10 with respect to the bottom shaft 11, the top shaft being driven from the bottom shaft through a toggle linkage gear train in the inboard stand 14, and means operative axially to shift one of the gears of the train to change the speed of the top shaft with respect to the bottom shaft or to disconnect the same. The top shaft 10 can be separated from the bottom shaft 11 in a vertical distance of 4-8 inches while gears 26, 68, 70 and 74 are always held in mesh regardless of the centre distance of shafts 10 and 11 by a pair of toggle links 58, 60 and 62, 63. The top drive gear 74 is held in any one of three selected positions as determined by locking set screw 78 into one of three annular grooves 79, 80 and 81. When the top drive gear 74 is in the left hand position as seen in Fig. 3 with screw 78 in groove 79, the smaller gear face 76 is meshed with the larger gear face of the top idler gear 70 so that top and bottom shaft 10 and 11 are equally geared. By shifting the top drive gear 74 to the middle position with screw 78 in groove 80, neither of the two faces 75 and 76 are in mesh with the top idler gear 70 and so shaft 10 is free to idle. By shifting the top drive gear 74 to the right hand position as seen in Fig. 3 with screw 78 in groove 81, the larger gear face 75 is in mesh with the smaller face of the top idler gear 70 so that the top and bottom shafts are unequally geared. In another embodiment the roller shafts are positioned as above and having the gearing as seen in Fig. 6. A toggle pin 98 includes two circular portions 108 and 109 concentric with each other journalling the toggle pin 98 for rotation in toggle links 96 and 97. These end portions 108 and 109 are however eccentric with respect to the centre portion 101 of the toggle pin 98 to which the links 102 and 103 are connected. Therefore rotation of the toggle pin 98 through 180 degrees moves gears 93 and 99 apart sufficiently to disengage them, thus allowing the top shaft to idle.

Filed: 1952-12-02
Abstract: 710,325. Abrasive band machines. PETTERSSON, K.H.R. Dec. 2, 1952 [Dec. 3, 1951; Dec. 3, 1951], No. 30483/52. Class 60 An abrasive band machine comprises a drive pulley 21, Fig. 2, a pinch pulley 25 to pinch the band against the drive pulley so that the run of the belt 31 in the outward direction is slack, and guiding and supporting means 43, Fig. 3, to engage the slack run. The means 43 consists of laminated members held by a resilient clamp 45 to a rigid plate 44. These members support the belt at its point of engagement with the work and the recesses at the stepped ends of the members form transverse air passages so that the belt floats on an air layer to reduce friction. The profile of the belt supporting face can be varied by relative adjustment of the members while the extent to which the latter project beyond the plate 44 controls their resilience. The plate 44 is attached to a swivel sleeve 13, Fig. 1, mounted in a guiding head 15 and pivotally connected by a pin 12 with a second swivel sleeve 9. The latter is connected by a pair of united rods 8 and a pivot pin 7 to a second pair of rods 6 secured to a flat casing 4 pivotally mounted on an axis concentric with the shaft 5 of an electric motor driving the pulley 21. A spring clip 17 holds the head 15 when the machine is not in use. A turntable 2 supports the electric motor on the base 1 of the machine. Two pulleys 23 and 24 mounted on the pivot pins 12 and 7 guide the band in both directions of its travel, the slack outward run 31 running outside the return run 22. The pinch pulley 25 is mounted on a spring-loaded lever 26 and pivotally supports a spring-loaded arm 28 carrying a pulley 29 to assist the band to run smoothly. If the belt is sufficiently uniform the pulley 29 may be fixed so that the band forms a free loop 29a under the action of centrifugal force. The pivotal members of the machine may be counterbalanced and the pulley 24 eccentrically mounted to avoid the tension on the belt being varied to any considerable degree by joint motion.

Title: Method of determining the angular position of a workpiece
IPC: G03F9/00
Filed: 1974-07-10
Abstract: 1468545 Method of determining orientation optically WETZLAR GmbH 10 July 1974 [11 July 1973] 30539/74 Heading G1A Apparatus for determining the angular position of a workpiece with an optically detectable elongate feature, comprises an optical correlator 3 rotatable about an axis and having an imaging system 2 and grating 4, means 5 and 6 for displacing the image of the feature relative to the grating 4, photo-cells 8 and 9 and means, to evaluate the signals from them and giving an extreme value when the feature is parallel to the grating furrows. Grating 4 has many straight furrows triangular in cross-section on a transparent carrier. The method is also claimed. Piezo-electric bender elements 5 and 6 oscillate perpendicular to the axis of correlator 3. The signals 8 and 9 are in anti-phase and their magnitude depends on the angle between the feature and the grating lines and is maximum for zero angle. There may be an additional oscillation of correlator 3 parallel to the grating lines and of frequency different from the lateral oscillation. The rectifier output is then applied to a second phase sensitive  rectifier. In the embodiment of Fig. 3 phase sensitive rectifier 14 receives a synchronous reference signal from generator 15 feeding motor 16 imparting rotational oscillations to correlator 3. On alignment of grating 4 and the feature, instrument 13 indicates a minimum. In the embodiment of Fig. 4 (not shown), motor (16) is fed through scanning amplifier (17) from A.C. source (15) and a D.C. source with potentiometer (18). It imparts to correlator 3 rotary oscillation with its zero point displaceable at constant speed. The signal, with the D.C. component removed is applied to amplifier (11), rectified, smoothed and differentiated so that alignment of grating 4 and the feature occurs at zero reading.
