IPC: H01J9/32
Filed: 1940-12-23
Abstract: 544,428. Sealing metal to glass. GENERAL ELECTRIC CO., LTD., and MARDEN, A. L., Dec. 23, 1940, No. 18052. [Class 36] In sealing metal members through glass by placing the members in one part of a die, pourmg molten or plastic glass into the die and causing the glass to flow round and contact the members by pressure from the other part of the die, the members are heated, as by downwardlydirected flames, before the glass is brought into contact with them so that they assume a temperature not substantially less, or greater than, that of the glass when it first touches them. In a rotary machine for making 8-pin bases for cathode ray tubes, the pins are loaded into the lower half of the die at A, and heated until they reach position B, molten glass being supplied at C; between D and E, the glass is pressed by downward movement of the upper half of the die, and cooling is effected between E and F, the base then being ejected on to a conveyer belt. The pins may be heated to about 1100‹ C., and the glass supplied at 1080‹ C. to 1100‹ C., pins and glass both being about 900‹ C. when they first touch. Specifications 475,665 and 522,444 are referred to.

Patent GB-486364-A (GB)
Title: Brush and method and apparatus for making same
IPC: A46D3/04
Filed: 1937-07-05
Abstract: 486,364. Brush - making apparatus. JACKSON, L. MELLERSH-. (Toledo Automatic Brush Machine Co.) July 5, 1937, No. 18649. [Class 19] [Also in Group XXII] Brush bristles 13, Fig. 16, are set in a stock 23 and held by metal anchors E<1> sheared from a continuous flat strip E, Fig. 1, laterally into a feeding nozzle A out of alignment of a driver D and pushed during shearing into the path of the driver. The strip E, which has a rounded edge so as not to cut the bristles, is fed by rollers actuated intermittently by a ratchet wheel G and pawl H on a bell-crank I again operated by a slide J, bell-crank K and cam L. A shaft M operates the cam L, driver D and nozzle A. The plane of the feed of the strip E, Fig. 7, is slightly offset from a channel C, and a shearing member O is located with its cutting edge in the horizontal plane at the bottom of the channel C. A co-operating movable shearing member P normally spaced from the member O for strip feed is subsequently moved to shear an anchor E<1> from the strip E and move it into the plane of the channel C into the path of the driver D. The member P forms one wall of the channel C and with the corresponding wall Q guides the anchor. When advanced by the driver, the anchor passes between plates C<1>, C<2>, which have grooved edges for engaging and guiding opposite ends of the anchor and holding it in alignment with the driver. The notching of the anchors is done by a pair of shear members R, R<1>, Fig. 1. The shear member R, Fig. 4, is a V-shaped grooved disc and has a cut-away segment for shearing corresponding with a similar cut-away segment in the member R<1>. The member R may be clamped in position, but the member R<1> is mounted on a rock-shaft S<1> intermittently operated by an arm S<2> extending laterally into a recess T in a housing T<1> forming the guide for the nozzle A. During the movement of this nozzle the arm S<2> will be rocked to shear notches from the strip E. The strip is firmly held against longitudinal movement at which time an anchor is sheared by the member P, Fig. 2, which is pivoted at P<2> and operated by cams P<3>, P<4>. All the parts are timed so that the shearing of the anchor from the strip and the movement into the path of the driver is slightly in advance of contact of the anchor and driver and subsequent to the feeding bristles through a slot B, Fig. 1, into registration with the channel C. The completion of the drive will spread the prongs of the anchor as shown in Fig. 16. The mechanism is stated to be capable of high speed due to positive feed and accurate guiding. Small anchors only are necessary requiring narrow brush backs and there is saving of material such as celluloid in the manufacture of toothbrushes.

Abstract: 600,285. Pulse and saw-tooth generating circuits. STANDARD TELEPHONES & CABLES, Ltd. July 20, 1945, No. 18708. Convention date, Dec. 20, 1943. [Class 40 (vi)] An " edger pulse " having one edge vertical and the other curved, is generated from a rectangular input pulse by deriving a secondary pulse having a curved edge, each input pulse and the corresponding secondary pulse being applied in opposition to a mixer to produce the edger pulse. A pulse 26 fed to the grid of valve 10, Fig. 1, causes the valve to conduct and discharge capacitor 22 rapidly, the capacitor recharging exponentially after the termination of the pulse to produce the waveform 34, Fig. 2. This waveform is added to the input pulse in mixer circuit 12 to produce the sharp pulse 40 and edger pulse 42, the former being removed by the limiter 14. By limiting at the level 45, a substantially linear saw-tooth may be produced. In a modification, Fig. 5, the input pulse is integrated over resistor R and capacitor C to give the waveform 54 which is fed to the grid of valve 81, the phase-reversed input pulse 61 being fed to the grid of valve 82. By providing a common anode load resistor 90, a waveform 95 results, which by limiting at appropriate levels produces the edger pulses 95a, 95b. Specification 600,284 is referred to.

Title: Improvements in or relating to trip devices responsive to the passage therethrough of a thickened portion of a movable medium such as a tape or wire
Inventor: SIBBALD FREDERICK
IPC: G11B15/22
Filed: 1955-06-29
Abstract: 789,305. Stop motions. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 11, 1956 [June 29, 1955], No. 18735/55. Class 120(2) [Also in Groups XVI and XXXVIII] A trip device responsive to the passage therethrough of a thickened portion of a tape or wire, comprises a pair of members 7, 8, such as rollers or posts, mounted for relative movement and adapted for passage of the tape 26 therebetween, a pivoted arm 5 carrying the roller 8, and a pivoted trip lever 15 arranged to co-operate with the arm, the latter being capable of holding the lever in the untripped position thereof. Means, e.g. a micro-switch 18, responsive to the movement of the lever between the tripped and the untripped positions of the lever, are provided. The arrangement is such that substantially no relative movement of the rollers takes place when portions of the tape of normal thickness pass therebetween, but the passage of a portion of the tape of abnormal thickness causes relative movement of the rollers and consequent pivoting of the arm to result in release of the lever to the tripped position thereof. As shown, the roller 7 is mounted on a bar 2 provided with a recess 2a into which the roller 8 projects and held by a screw 4 on to a base plate 1, the bar being adjustable to vary the spacing between the rollers. The arm 5 which includes a bracket 13 and is urged in an anticlockwise direction by a spring 14 so that the bracket abuts a screw 12, has a knife-edge 24 engageable, in the untripped position of the device, with the lever 15, clockwise movement of the latter being limited by a pin 17. The switch 18 has a protruding plunger 19 urged outwardly by spring means and bearing on a bracket 20 of the lever to urge the latter in a clockwise direction. In operation, when the thickened portion 27 of the tape 26 enters between the rollers 7, 8, the roller 8 moves to the fullline position, Fig. 4, so that the arm 5 is pivoted in a clockwise direction and the edge 24 thereof rides over the edge 25 of the lever 15, the force exerted by the plunger 19 thereby causing the lever to pivot in a clockwise direction to abut the pin 17. The outward movement of the plunger actuates the switch so that movement of the tape is arrested, for example, by interrupting the circuit of. a motor driving the tape or by applying a solenoidoperated brake. Resetting of the device is effected by pressure applied to the lever in the direction of the arrow 28 or by a mechanical coupling from a starting knob or other control member forming part of the apparatus in which the device is incorporated.
