Inventor: STILLWELL PETER FREDERIC THOMA
IPC: H04N5/235
Filed: 1951-12-08
Abstract: 735,700. Automatic control systems for television cameras. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 3, 1952 [Dec. 8, 1951], No. 28810/51. Class 38 (4). For the purpose of controlling an iris diaphragm of a television camera signals generated by the camera are applied to the grid-cathode circuit of a cathode follower valve 1, Fig. 1, the output of which renders a diode 4 non-conductive when the camera signals are greater than 80 per cent of their maximum and renders a diode 7 non-conductive when the camera signals are less than 10 per cent of their maximum. The current through a diode 7, which shares a common anode 6 with diode 4, thus varies with the camera signals between these limits only and a corresponding voltage is produced across a resistor 8. This voltage is smoothed by a resistor-condenser network 9, 12 and applied to the grid circuit of a triode 10 which shares a common cathode resistor 13 with a triode 16 to the grid-cathode circuit of which a reference signal is applied. Relays 14, 15 in the anode circuits of valves 10 and 16 are arranged to be inoperative for a normal average intensity of 45 per cent of maximum, one or the other operating according to the sense of deviation of the average intensity from this value, to restore it by operation of an electric motor adjusting the iris diaphragm. Progressive control of the motor operating the iris diaphragm and a lower limit at the black level instead of 10 per cent maximum are referred to. Specification 444,074, [Group XL], is referred to.

Abstract: 821,684. Making twist drills, milling cutters and the like; extruding. GOTZE, F. Oct. 11, 1955 [Oct. 11, 1954], No. 29001/55. Classes 82 (2) and 83 (4). Apparatus for the production by extrusion of fluted tools such as twist drills, reamers, milling cutters, broaches, comprises a one-piece extrusion die 9 through which a blank is extruded to form the tool, and a withdrawal die 8 which grips the shank of the tool and withdraws the latter from the extrusion die during the return stroke of the extrusion press. The die 9 has helical grooves 72, Fig. 6, for forming the flutes and is retained in a die holder 11 by a plate 12. The die holder is secured in a bolster 15 of the press which also contains a guide bush 20 for the extruded tool. The blank is forced through the extrusion die by a ram 2 connected to an upper cross-head 1 of the press. The withdrawal die 8 is mounted in a plate 7 and has a conical aperture 8a which forms a key for the conical shank of the tool 10. Upon the return stroke of the cross-head 1, the enlarged ends 17 of withdrawing rods 17 engage the plate 7 and raise it together with the withdrawal die 8 and the tool 10 from the bolster 15. The die holder 11 is thereby urged against a ball bearing 19 and is thus permitted to rotate together with the extrusion die 9 during the raising of the tool 10 whereby the die is screwed out of the flutes on the tool. The helical grooves 72 formed in the die 9, Fig. 6, have entrance portions 71 and exit portions 73. Comparison is made between the twist drill produced by the apparatus of the invention and twist drills produced by milling and by forging, rolling or by extrusion using a split die.

Abstract: 1,014,900. Sensing record cards. AMP Inc. July 15, 1964 [July 22, 1963], No. 29036/64. Heading G4M. A punched card reader comprises a drawer 30, Fig. 4, on to which the card is placed with its rear edge abutting face 104, and a set of contact springs 216 against which the card is moved when the drawer is closed to establish contact with printed conductors on plate 118 through the holes in the card. With the drawer in the open position shown in Fig. 4, the card is inserted and its front edge tensions a spring member, the end portions 128, Fig. 7, of which project above plate 118. The drawer is moved to its closed position by rotating a handle 28, Fig. 5, this causing rotation of a bifurcated member 52 and the camming of block 62 to the left and upwards as seen in Fig. 4, carrying drawer 30 with it. When the drawer 30 has been fully inserted switch 36, Fig. 7, and a pair of switches 172 are closed to energize the conductors on plate 118, the output being taken from leads connected to spring contacts 216. If the card has been wrongly inserted with a rounded corner on its leading edge, one of switches 172 is not closed by the associated end 128 of the spring member and no output is obtained. To eject the card, the handle 28 is rotated in the opposite direction. At first, the card is retained on spring contacts 216, and the spring member is tensioned further by virtue of the engagement of its ends 128 with the edge of the card. The card is then released and abuts against face 104 until a pivoted ejection member 144, Fig. 4, raises the edge of the card over face 104 and the spring member ejects the card from the drawer. When the card has been ejected and the operating handle released, springs 162, Fig. 4, urge the drawer back towards its closed position so as to lower ejection member 144 and permit the insertion of another card. Power is supplied to the printed circuit conductors on plate 118 by way of a spare row of contact springs 216, these rows being connected to a common voltage source or to the contacts of a stepping switch if serial read-out is required.
