Filed: 1970-08-13
Abstract: 1300836 Lasers INTERNATIONAL BUSINESS MACHINES CORP 13 Aug 1970 [29 Sept 1969] 39018/70 Heading H1C The resonator of a pulsed laser includes an optical delay element which compensates for dispersion of the pulses' group velocity within the active medium, thereby allowing picosecond pulses to be produced. In Fig. 1, a Nd glass laser rod 1 is disposed between mirrors 3, 4, and is mode locked by a saturable dye cell 2. The delay element comprises a glass block 7 having a partially reflecting face 6 which forms an interferometer with mirror 3, the air gap 5 being adjustable by a piezoelectric crystal on which mirror 3 is mounted. The air gap is chosen such that the interferometer is phase dispersive for a given pulse duration but is not amplitude dispersive. The minimum pulse duration is about six times the delay t introduced by the interferometer. For example, with an Nd<SP>3+</SP> glass rod, a minimum pulse duration of 5À10<SP>-13</SP> sees. is expected from an interferometer of t = 0À8.10<SP>-13</SP> sees., corresponding to an air gap of 12 Á. When longer pulses are used, a multiple reflection interferometer as shown in Fig. 3 may be used. Surfaces 14, 15 and 16 are highly reflecting, the latter acting as a resonator mirror. Surface 12 is partially reflecting. Dye or gas lasers may also be used.

Title: Improvements in or relating to process and apparatus for severing glass
IPC: C03B33/02
Filed: 1929-12-24
Abstract: 338,045. White, A. E., (Pittsburgh Plate Glass Co.). Dec. 24, 1929. Cutting.-A method of removing the thickened edges of a, glass sheet which is produced as a continuous, ribbon by a drawing-process consists in heating the glass along lines parallel with, and close to, the edges for a distance corresponding to the length of a section to be severed from the ribbon, removing the section, and then applying a cooling-device to the heated lines to cause the glass to crack along the lines. The invention is used in conjunction with an apparatus for cutting a continuous ribbon of glass into sections. This apparatus comprises two horizontal strips 16, Figs. 1 and 3, of metal having a high electric resistance, which are arranged on each side of the path of the glass ribbon 2 as it moves upwards into a leer of the Fourcault type. The strips 16 are carried by levers 12 pivoted to a frame 11 which is carried by a cable 7 connected to a counterweight 10. The strips are electrically heated and they are brought into contact with the glass ribbon 2 by means of a solenoid 19, the suspension of the frame, 11 allowing the strips to move upwards with the ribbon while they are heating it along a transverse line. The edge-heating device, which forms the present invention, consists of two electrically-heated strips 29 carried by bars 28 which are attached to brackets 32 that project upwards from the frame members 11. The lower end of each bar 28 is pivoted to the supports of one of the transverse strips 16, while the upper end of the bar is pressed by a spring 33 towards the glass ribbon. Thus the ribbon, while, being heated along a transverse line, is also heated along two lines near its edge. When a section of glass has been cracked-off the ribbon along the transverse line, it is deposited in a rack and a cold tool is applied immediately to the lines heated by the strips 29. The glass cracks along the heated lines and the edge portions can be removed.

Title: Improvements relating to electronic selector circuits
Inventor: PERKINS DENIS GORDON
IPC: F16D65/095
Filed: 1958-12-08
Abstract: 934,175. Electronic distributers. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 8, 1959 [Dec. 8, 1958], No. 39550/58. Class 40 (3). In an electronic distributer comprising a number of valves interconnected so that only one valve is switched on at any instant and so that the valves are switched on cyclically, the signals to be transmitted are applied to respective input electrodes of the said valves via appropriate gates which are respectively opened and closed in response to the switching-on and switching-off of the valves so that signals selected during the successive switched-on periods of the valves can be derived from a common output circuit of the valves. If, for example, the valve V1 is conducting, the reduced voltage applied to the grids of the valves V2, V3 holds them in the cut-off condition. Also, the relatively high potential of the grid of the valve V1 renders the diodes D1, D4 conductive so that a signal pulse present at the terminal SI1 is passed via the diode D1 to the grid of the valve V1 and can be taken from its cathode and applied through a clamping circuit LC to the output terminal OT. A negative triggering pulse applied at the terminal TP1 passes via the diode D4 to the grid of the valve V1 which cuts off and passes a positive pulse from its anode circuit to the grids of the valves V2 and V3, the pulse to the latter valve being considerably attenuated by the resistor R9 so that solely the valve V2 is rendered conducting, and the valves V1, V2 are held in the cut-off condition. The pulse at SI2 now passes to the output terminal OT, and the subsequent negative triggering pulse at the terminal TP1 cuts off the valve V2 so that V3 is made conducting, and the pulse at SI3 now passes via diode D3 to control the valve V3 so that from its cathode circuit the signal is passed to the terminal OT. The clamping circuit LC is arranged to act as a limiter to remove any differences in the steady current through the respective valves V1, V2, V3 when they are in the switched-on condition. The distributer, or selector switch, may be used for black level and gamma control signals for the colour channels of a 3-colour television system with field trigger pulses applied at the terminal TP1. The circuit may be modified so that the output is taken from a common impedance in the anode circuits of the valves V1, V2, V3.

Abstract: 936,810. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 21, 1960 [Nov. 19, 1959], No. 40024/60. Class 40 (4). In an inter-exchange system employing VF signalling in which each digit is represented by one or more frequencies, each digit is sent until it is terminated by a return signal from the receiving exchange, whereupon the return signal is cut off in turn and the next digit is sent. Digit sending may be initiated by a " ready " signal from the receiving exchange. Receiving equipment including registers is shown for signals comprising a 2 out of 6 code with relays R1 . . . R6 corresponding to the six frequencies. If more than two frequencies are received R12 operates, while if only one frequency is received R 13 operates, an alarm circuit AL being closed in either case. Assuming a correct signal is received, the corresponding relays in register RE1  operate as well as R8, and these relays connect up R11 to send a return signal. R11 holds over its lower winding during the operating time of R10, which fixes a minimum duration for the return signal, and over its upper winding in series with the operated pair of relays R1 . . .  R6 until the received signal is ended. R11 and R10 then fall back and R9 comes up, the digit represented by the next signal being stored in register RE2. In an alternative arrangement, a signal is normally transmitted from the receiving exchange, and its interruption constitutes the acknowledgment of a correct digital signal.

Title: Camera bellows device having an automatic diaphragm-interlocking mechanism
IPC: G03B17/04
Filed: 1975-10-06
Abstract: 1496818 Diaphragm and shutter mechanism NIPPON KOGAKU KK 6 Oct 1975 [7 Oct 1974] 40796/75 Heading G2A A camera device has a bellows portion extending between a mount portion which attaches to the camera and a lens mount portion, the lens mount portion having a diaphragm-controlling member which stops down the diaphragm during shutter release irrespective of whether the lens mount is installed in normal or reverse position. As shown, the bellows 10 extends between the camera mount 3, which attaches to the camera 1, and the lens mount 8 carrying the picture-taking lens 6. Both mounts 3 and 8 are slidable on a rail 4, the movements being controlled by respective operating knobs 5 and 9. A slide 11, spring-urged downwards, is restrained by an actuating lever 2, see also Fig. 4 (not shown). Lever 2 moves down into position 2' when the shutter release button is pressed, so that slide 11 is also released to move down. This causes a bell-crank 13 to pivot anticlockwise, so causing a bar 14 to which it is linked to also move down. It is thus brought into engagement with one arm 15b of a rocking member 15 having two arms 15a, 15b pivoted by end-pieces 15c to the rail 4, so that the rocking member is pivoted anti-clockwise. The lens mount 8 has a pair of slidable bars 20, 21 which bear against the arms 15a, 15b of the rocking member. A lever 22 forming part of a bell-crank lever 24 is linked to bar 20. Thus as rocker 15 pivots anti-clockwise, as described above, bar 20 is pushed upwards so that bell-crank lever 24 is pivoted anti-clockwise, Fig. 5. An aperture ring 26 carried by the lens mount is biased anti-clockwise by a diaphragm lever 7 bearing against a lug 26 on the ring, whose movement is prevented by engagement of a projection 26a on the ring with a stop 25 on lever 24. When lever 24 is pivoted anti-clockwise, stop 25 disengages from projection 26a, so allowing the aperture ring 26 to be rotated anti-clockwise by lever 7, and so stopping the aperture down to its pre-set value, after which the shutter is released to effect an exposure. After release, the mechanism parts are returned to the Fig. 1 position. To reverse the lens the lens mount 8 is removed from the end 10a of the bellows, and replaced with the end 6a of lens 6 attached to the bellows end 10a. The arrangement is now as shown in Fig. 6. On operating the shutter release button, the rocking member 15 pivots anti-clockwise as before. This time the bell-crank lever 24 will pivot clockwise, since it has been reversed. Thus stop 25 releases ring 26 to be rotated clockwise, and so stop down the diaphragm as before.
