Title: Light intensity measuring apparatus
IPC: G03B7/083
Filed: 1967-04-06
Abstract: 1,134,995. Photographic apparatus &c. KABUSHIKI KAISHA HATTORI TOKEITEN. April 6, 1967 [April 9, 1966], No.15844/67. Heading G2A. [Also in Division G1] The intensity of incident light is indicated by the position at which a displaceable member driven at a predetermined rate is stopped by an electromechanical device in response to the voltage developed across a capacitor which is charged through a photo-conductive element on which the light is arranged to fall. The arrangement is incorporated in a camera shutter including in its electrical circuit two pairs of contacts whereby the capacitor is short circuited, and charged respectively, transistor amplifiers controlling energization of the electro-mechanical device, a temperature compensating varistor and a switchable battery checking circuit. The mechanism is operated by moving downwardly a bar 1, Fig.1, which simultaneously moves a member 5 out of contact with a pin 10 of a rotatable cam member 8 and subsequently out of its path, closes the battery supply contacts 61, 62, and releases the mechanical latch of a member 39 which is then held solely by armature 43 of the electro-mechanical (solenoid) device. Subsequently, through pin 3 and intermediate member 16, beak detent 25 is withdrawn so that rotation of cam 8 by a spring through a gear chain and under the control of an escapement, is permitted, and contacts 64, 65 are opened to commence charging the capacitor. After a time interval depending on the light intensity the electromagnet is de-energized and releases armature 43 to permit rotation of member 39 which halts the movement of the escapement to locate cam 8, and through an element 55 lifts a detent from shutter operating bar 52 so that it is driven to the left by a spring forked lever 45 under the control of escapement 46. Movement to the left is terminated, and the shutter actuated by a pin 48 on lever 45 engaging the cam surface of member 8 which is set according to light intensity. The mechanism is reset when bar 1 is released.

Filed: 1970-04-03
Abstract: 1299004 Electron multipliers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 April 1970 [4 April 1969] 15966/70 Heading H1D An electron multiplier comprising channels coated internally with a secondary emission layer, is characterized in that the emission layer at the input end has a higher secondary emission ratio than the rest of the channel to equalize the amplification and improve the pulse height distribution. The layer of higher emission may be of gallium arsenide or gallium phosphate and may extend for a depth l equal to d/sin #, where d is the diameter of a channel and 8 is the inclination of the channel to the incident electrons; the layer may be applied by vaporizing or sputtering from a direction with a smaller angle of incidence. The differing emissive layers may alternatively be obtained by building a multiplier from two channel plates coated with materials of different secondary emission ratios; when several channel plates are used, the ones more remote from the input may have larger diameters to give better linearity in the output signal.

Title: Improvements in or relating to electric wave filters
Inventor: WALL PETER KENNETH
IPC: H03H7/01
Filed: 1957-05-22
Abstract: 813,962. Bridged-T filter networks. STANDARD TELEPHONES & CABLES Ltd. May 22, 1957, No. 16215/57. Class 40 (8). A filter having a narrow band-pass comprises a symmetrical T-network of three inductors L 7 , L 7 , L 8 , Fig. 1, the two series inductors being bridged by a series resonant network or device 5 (e.g. a piezo-electric crystal), and by a capacitor 6, two further series capacitors C 1  being arranged between the inductors and the filter terminals. Alphabetical reference symbols also denote values of corresponding elements. The capacitor 6 is adjustable and the total effective capacity (including that of the crystal 5) shunted across the inductors is C 2 . A shunt resistance R 3  is included to balance the resistive components of the elements. The circuit is designed by finding the component values of the known m-derived filter of Fig. 2 which give the required characteristic assuming an image impedance R o  which is much greater than the image impedance R 1  desired for the final circuit. The intermediate circuit of Fig. 4 is then arrived at by deriving the network inverse to Fig. 2 (Fig. 3, not shown) and transforming the resulting #-network of three inductors into the T-network L 7 , L 7 , L 8 . The shunt elements C 1  are now transformed to series elements (see Fig. 10) of the same value, with the result that the impedance of the filter becomes R 1  = 1/# 02 C 1 R 0  instead of R o . Although the value of R 1  varies with frequency, the pass-band is narrow enough to make the effects of this negligible. The effect of adding R 3  in shunt with L 8  is to cause effective resistances R (not indicated) to appear across each pair of terminals, these representing the dissipation of the network. For convenience, the resistances R may be considered to be series elements of value R 4 #1/#0<SP>2</SP>C 1 R, where several filter sections 11, 12, 13, &c., Fig. 11, are connected in cascade, the effect of resistances R 4  may be compensated by the addition of shunt resistances R 5  which over the pass-band form T-networks of image impedance R 1  with the effective resistances R 4 . The combination L 6 , C 3  is replaced in Fig. 1 by the crystal 5.

Abstract: 372,581. Typewriters. STARK, H., 46, Augustenstrasse, and EIBERT, F., 11, Kanalstrasse; both in Munich, Germany. June 5, 1931, No. 16424. Convention date, June 11, 1930. [Class 100 (iv).] Type-lever actions ; letter-spacing mechanism. -The universal bail is so connected to the carriage escapement, and the escapement is so formed that, besides spacing the carriage, it returns the type-levers without the use of return springs. The type-lever i, Figs. 1 and 2, is actuated by the key-lever j through a lever j<1>, and the nose i<1> on the type-lever strikes the universal bail b just before the moment of typing. The bail is thus driven back, moving an arm a which operates the escapement. The escapement consists of a disc s, bearing two concentric ratchet-wheels e, e<1> which leave a zig-zag path e<0> between them. In this path a roller c at the end of the arm a moves, the arm a being prevented from moving otherwise than radially by a supporting-arm d. ' The escapement has a tendency to rotate in the direction of the arrow, due to the carriage-rack b, coupled with it by the cog and ratchet g, f. Then as the arm a moves inward the roller c clears a tooth of the ratchet-wheel e in which it was housed and releases the carriage. The escapement rotates, and the roller c comes against a slope of the ratchet-wheel e<1> and is driven back smartly by the rotation so that the bail strikes the nose i<1> and returns the typelever. The roller c finally comes to rest in the next tooth of the ratchet-wheel e. The escapement, shown in Fig. 4, is in the form of a double rack h<0>, h<2> with pawls a<1>, a<0> engaging with them alternately. The pawls are connected by a link d<0> so that when pawl a‹ engages with rack h<2>, pawl a<1> does not engage rack h<0>, and vice versa. The arm a<1> is connected, as described above, to the bail. By the provision on the type-lever i of a straight part instead of the hook, for engaging the pin of the lever j<1> the motion of the type-lever is accelerated and, if desired, the segment and the type-levers can be lifted out as a unit.
