IPC: E06B7/18
Filed: 1954-04-14
Abstract: 761,905. Sliding bolts. LOWE, J. C. April 12, 1955 [April 14, 1954], No. 10926/54. Class 44. [Also in Group X] A vertically movable draught-excluder which is housed in a slot near the bottom of a door and co-operates with a fixed strip secured to the floor and over which it rides on opening or closing the door (see Group X) may be locked in its lowered position by a bolt 38 to retain the door in the closed position. The upper end of bolt 38, which is housed in a casing 37, is recessed to correspond with a fixed plate 40 and is grooved at 42 to accommodate two leaf-springs 43, 44, which are secured to bolt 38 near its lower end. The spring 43 provides frictional restraint whereas spring 44 has a cranked portion 45 which is apertured to engage a pin 46 projecting from bolt 38 into groove 42. The plate 40 is slotted to pass pin 46 and the latter has a stop 47 for the spring 44. On inserting a toothed key into keyhole 52, the teeth engage a rack 49 formed on bolt 38 and spring 44 is moved to the left to disengage portion 45 from a shoulder 48 on plate 40. Rotation of the key moves the bolt 38 and removal thereof permits spring 44 to engage under the bottom of plate 40.

Title: An improved machine for carrying out pressing and other operations on strip material
IPC: A47G1/06

Abstract: 552,392. Cables. BRITISH INSULATED CABLES, Ltd., HARGREAVES, E. S., and STEWARD, H. M. Sept. 1, 1941, No. 11131. [Class 36] [Also in Groups XXII and VIII] In a press for stamping, cutting, punching &c. strip material, two strips are operated on simultaneously and are then combined. with a preformed core to form a high-frequency cable. Two strips 1 may be fed from drums 38, 39, Fig. 8, by dies 4, 6, Fig. 1, of which the dies 4 are fixed to, and 6 are vertically movable on a slide 3 which is reciprocated on bars 7 by crank discs 8 and rods 9. The dies 6 are pressed away from the dies 4 by springs 17 and are connected to the slide 3 by a parallel motion device 14, 15. During the movement of the slide 3 to the right, rollers 21, on levers 58, engage cams 22 and force the dies 6 towards the dies 4 thus giving a corrugated channel form to each of the strips 1 between them while feeding them. During the return movement of the slide 3, the steep faces 26 of the cams engage the rollers 21 swinging them aside so that the dies do not engage the work which is retained by weighted detents 33. Cross bars 37, attached to the moving dies, free the strips from the fixed dies 4. In a modification, Figs. 5, 6, these bars may be replaced by strip guides 92, 98. Side guides 86 and tensioning device 96 may be provided between the supply drums and the dies. The strips may be looped over guides 67, Fig. 8, and fed continuously, by means not shown, through guides 69, 70, which apply it to a core 2, and through a rotary device 73 which applies a helical tape. The fixed dies may be adjusted laterally by screws 88, Fig. 6, and the outward movement of the dies 6 be limited by nuts 20 on rods 19.

Abstract: 336,551. Hansen, B. Hohn-. April 8, 1929, [Convention date]. Harpoons.-An electrical conductor is attached to an harpoon for electrocuting whales. As shown in Fig. 2 the insulated cable 1 may be attached to a metal rod 2 which extends through the shaft 3 to the head 4. The shaft has an open slot 5 in which the cable 1 is placed when the harpoon is to be discharged from a gun. As shown in Fig. 4 the cable 1 is attached to a sliding contact at the front part of the slot 8. During the discharge the contact slides back along the slot 8 and automatically closes the circuit to the head of the harpoon when it reaches a contact socket 10.

Title: Image pick-up apparatus

Abstract: 1340088 Television; cathode-ray tube circuits WESTERN ELECTRIC CO Inc 27 April 1971  [1 May 1970] 11541/71 Headings H4F and H4T In a television system "Zooming" is effected by altering the size of the scanning raster in the pick-up tube without altering the aspect ratio. Thus, when the whole of the target 11 (Fig. 2A) is scanned the picture reproduced by a cooperating receiver is as shown in Fig. 2B, whereas when the raster size is reduced the reproduced picture is as shown in Fig. 2C. One arrangement for the raster size control comprises a potentiometer P1 (Fig. 1) which supplies an adjustable D.C. voltage Vz to the bases of transistors Q4, Q104 in the charging circuits of the sawtooth capacitors C1, C101 of the vertical and horizontal deflection circuits respectively. When the sawtooth amplitudes are altered, a transient D.C. shift occurs which, in the case of the horizontal deflection circuit, dies out rapidly before a noticeable picture shift is produced but, in the case of the lower frequency vertical deflection circuit, the settling time is so long that compensation is required and thus is achieved by supplying the "zoom" voltage Vz to the base of the sawtooth switching transistor Q2 via a resistor R3 the value of which in relation to the value of resistor R2, is so chosen that the voltage to which sawtooth capacitor C1 is discharged (at point B) is shifted to offset the change in the D.C. level at point C caused by the change in the peak-to-peak amplitude during "zooming". The position of the raster may be adjusted by potentiometers P8, P10 and the extent of adjustment is range limited by potentiometers P7, P9 mechanically linked to the "zoom" potentiometer P1 to ensure that the raster cannot be shifted outside the target. Initial centring and size control of the raster is effected by potentiometers P13, P113 and P17, P117 respectively. The pick-up tube 11 is preferably of the type in which the target is composed of photo-diodes to avoid the "raster burn-in" effect produced by tubes such as vidicons. Other arrangements for raster size control comprise identical variolossers (shunting the outputs of the horizontal vertical deflection generators) each consisting of a resistor in parallel with a field effect transistor to the base of which the "zoom" voltage Vz is supplied (Fig. 4, not shown) or, alternatively identical linked potentiometers may be employed (Fig. 5, not shown). The range limiting of the position control adjustment, e.g. that for the vertical position, may be modified by replacing potentiometer P7 (Fig. 1) by a unity gain transistor amplifier shunting P8 and supplying the zoom voltage Vz to the base of the transistor (Fig. 6, not shown).
