Title: Electronic timepiece
IPC: G04G5/04
Filed: 1975-02-21
Abstract: 1474002 Electronic watches DAINI SEIKOSHA KK 21 Feb 1975 [7 March 1974] 7441/75 Heading G3T [Also in Division H1] In an electronic timepiece having a display (1), Fig. 1 (not shown) with several portions e.g. for the date, day, hours, minutes and seconds, a stem 17 is mounted on a base-plate 15 for axial and rotary movement and controls at least three switches to correct the display. Inner and outer positions of the stem are defined by a flange 27b of a spring 27 engaging the stem on respective sides of collar 17b. Square portion 17a of the stem carries a switch member 22, and a spring 24 biases this member and thus the stem to a central position in rotation. With the stem in its inner position as shown, all the switches are open and the watch runs normally. When the stem is pulled out, its end 17d allows a contact spring 18 to touch a contact pin 19, these parts forming an enabling switch 13 so that, by logic circuitry Fig. 2 (not shown), further switches 10-12 are rendered effective. The switch 10 is a function selector switch formed by a contact 25 and a lug 22a on member 22, so that if the stem 17 is now rotated clockwise this switch is closed and switch 11, which is a correcting switch, is connected via the logic to the date display (2) which becomes illuminated to show that it is available for correction. The switch 11 is formed by a second contact 26 and lug 22b and rotation of the stem anti-clockwise thus causes 1Hz pulses to pass to the date display. Subsequent clockwise rotations of the stem connect the switch 11 successively to the day, hours and minutes display portions (3-5), the selected portion being illuminated. Depression of the stem, while still in its outer position, against a spring 23 and contact spring 18, will cause the latter to touch a contact 20, thus closing switch 12 and setting the seconds counter (204) and display (6) to zero. The display is of liquid crystal type, illuminated by a lamp (9) when a switch 14 is closed. This switch is formed by the spring 18 and a further fixed contact 21 and is closed by depressing the stem in its inner position. The switch 12 is also thus closed but is ineffective since switch 13 is open.

Title: Improvements in or relating to the manufacture of lenticular viewing screens
Inventor: WHATLING FREDERICK WILLIAM
IPC: G03B21/62
Filed: 1950-03-30
Abstract: A method of making a metallic pressing matrix for pressing a lenticular viewing screen, such as that used with a projection-type television receiver, comprises forming a helical groove having a multiplicity of convolutions or a multiplicity of separate grooves on a member of circularly-tubular form, opening the member about its longitudinal axis so as to reduce its curvature and thereby form the pressing matrix.  In the preferred method a helical groove or series of separate grooves is formed on a wax cylinder.  The surface of the cylinder is then made electrically - conducting and a metal shell preferably of copper is then electro-deposited on the cylinder.  The shell is cut longitudinally, removed and flattened to form a rectangular copper matrix.  In a modification the groove or series of grooves is formed on a metal cylinder on which the copper shell is electro-deposited, the shell being afterwards cut longitudinally and removed.  In a further arrangement a groove or series of grooves is formed on a thin metal tube subsequently cut longitudinally or on a thin sheet of metal stretched over a cylindrical mandrel with the edges of the sheet abutting.

Title: Speed indicating apparatus
IPC: G01P7/00
Filed: 1945-03-31
Abstract: 596,666. Speedometers. KAEBURN, L. K. March 31, 1945, No. 8151. [Class 40 (i)] [Also in Group XX] - In a speedometer, the frequency of a pair of oscillators is varied respectively in accordance with the acceleration and deceleration of the system and the frequency variations are integrated. As shown, the frequencies of two oscillators 22 and 23, Fig. 1, are controlled by the potentials appearing across crystals 55 and 56, Fig. 5, which are attached to gimbal ring 46 of gyroscope 45, Fig. 5. The pressure on, and hence the potential across, piezo-electric crystals 55 and 56 is varied in accordance with the acceleration of the system by means of the pivotally mounted weight 65, Fig. 5. The potential across crystal 55, say, is amplified by valve 75, Fig. 7, whose output controls the current through charging pentode 78 and hence the frequency of saw-tooth oscillator 77. The oscillator output is fed to amplifier, valve 79 which drives output valve 80, driving synchronous motor 24. Crystal 56 and synchronous motor 25 co-operate in a similar way. Motors 24 and 25 operate integrating gears 27, 28 and 29, so that potentiometer arm 30 is displaced in proportion to the velocity of the system, a voltmeter 31 is associated with arm 30 to read velocity. An inclinometer 43, 44, Fig. 1, is associated with the gyroscopic system 21. A similar arrangement is provided for measuring lateral velocity and inclination. Gyroscopic system 21 comprises gyroscope 45, Fig. 4, which is mounted within gimbal rings 46-49, and correcting means, consisting of-a mercurycontaining cup, with centre electrode 105, Fig. 3a, and four other electrodes 101-104, moulded into it, so that any departure from the vertical causes the mercury to close the circuit of one of electromagnets 106-109, so that stabilizing rod 110 returns to the vertical. To prevent acceleration operating the correcting means, a cut-out 112 is provided to render the means inoperative during acceleration. Also a mass 52 is provided to prevent any appreciable movement of ring 48 during correction. In a modification, velocity variations may be translated into pressure variations by means as in Fig. 6 (not shown) of a mass supported in two or more directions by pin-like supports associated with piezo-electric crystals. The oscillation may also be frequency modulated by means of a U tube containing mercury, which in conjunction with an outer electrode forms an acceleration varied'capacitance as in Figs. 9 and 10 (not shown). A D.C. potential proportional to pressure may also be obtained from each of the crystals by maintaining them in oscillation and rectifying the outputs as in Fig. 8 (not shown).

Abstract: 119,049. Lymn, A. H., and Rambush, N. E. June 13, 1917. Ammonia and ammonium salts.-To separate out ammonia from steam and tar contained in producer gas, and to obtain from the ammonia. clean salts of any acid, the gaseous mixture, after it has been washed in known manner at a temperature of about 80‹ C. in water which may contain lime, is passed through a tubular or like condenser, or condensers, arranged to act as reflux condensers, the part of the condenser at which the mixture enters being kept at such a temperature, e.g., 80‹ C., that the steam and tar are simultaneously condensed, but any ammonia which condenses with them is immediately volatilized. The other end of the condenser system is kept at such a temperature, e.g., 40‹ C., that practically all the steam and tar are condensed, but not the producer gas and the ammonia which is passed through a tar separator to remove final traces of tar. The ammonia is then converted into any desired salt by passage through an acid, and the gas is left in a-pure condition. Any ammonia which is contained -in the condensate from the reflux condenser is volatilized by any known method. Two or more condensers in series or parallel may be used.

Abstract: 580,112. Frequency changing. AUTOMATIC ELECTRIC LABORATORIES, Inc. May 6, 1944, No. 8618. Convention date, May 6, 1943. [Class 38 (ii)] A self-starting frequency reducing system producing currents of a frequency which is an even subharmonic of the input frequency in a load parallel with a capacitor, comprises a balanced network of saturable inductances biassed by a direct current. Four similar inductances 25, 26, 27, 28 form a bridge into which at 15, 16 A.C. and magnetically biassing D.C. from sources 10, 11 are fed in series. Oscillations are produced in a capacitor 14 of a suitable value, connected to the opposite corners 17, 18 of the bridge, having a frequency which is an even subharmonic, preferably a half, of the input frequency, and a load LD in parallel with the capacitor 14 takes a current of that frequency. Above a certain load failure of supply occurs but as the impedance of LD increases output automatically begins. The output voltage is substantially constant for varying loads and input volts, resulting from phase shift between the input and output circuits, and the balanced bridge eliminates subharmonic current from the input circuit. A modification is described in which the pairs of inductances 25, 27 and 26, 28 are wound on common cores and the D.C. source is in parallel with the A.C. input source Fig. 2 (not shown). In a further modification the biassing D.C. obtained from a rectifying bridge is supplied to separate coils on the common cores, and the load is supplied by transformer action to further separate coils whereby the output voltage can be selected as desired.
