Title: Improvements in or relating to an electromagnetic oscillating armature arrangement for timepieces
IPC: H02K33/10
Filed: 1965-10-22
Abstract: 1,118,817. Oscillating electric motors. G. SCHWARZKOPF. 22 Oct., 1965 [23 Oct., 1964], No. 44927/65. Heading H2A. [Also in Divisions G3 and H1] An electromagnetic oscillating armature arrangement for driving a timepiece comprises a stationary electromagnet 10, 13, a magnetic armature 1 and a magnetic switch 6 connected to a circuit supplying current to the electromagnet, the magnetic switch being periodically actuated by the magnetic field of the armature but not by the magnetic field of the electromagnet. In the rest position, the magnetic field of the armature 1 closes the magnetic switch and allows a battery 11 to provide a current to the solenoid 10 which creates a magnetic field in the gap between the polepieces of the electromagnet. The armature, fixed to a spiral spring 3, is therefore rotated in the direction of arrow 14 until the magnetic field of the armature no longer influences the switch 6 which then opens. The magnetic field of the electromagnet is therefore withdrawn and the armature returns to its rest position. A resistor 15 which may be variable is used to control the field intensity of the electromagnet. In a modification the armature is disc shaped. The field intensity of the electromagnet may be adjusted by electromagnet polepieces which are movable. Alternatively the field strength may be controlled by a metallic or magnetic member the position of which is adjustable. The voltage drop with time of the battery may be counteracted by inserting in series with the electromagnet a second oppositely wound electromagnet. Several electromagnets co-operating with a multipolar armature may be used and the armature may take the form of a pendulum.

Title: Lens System
IPC: G02B15/02
Filed: 1967-10-05
Abstract: 1,154,785. Optical objectives. INTERNATIONAL BUSINESS MACHINES CORP. Oct. 5, 1967 [Dec. 8, 1966], No.45431/67. Heading G2J. An objective for use at a plurality of different conjugate object and image distances for different magnification ratios, e.g. for micro-filming in which a reduction of 50X, 40X, 30X, 20X, 17X and 15X is required, comprises a group of lens elements I - VIII and means for changing the effective shape of one lens element V so that a substantial effect is produced only on the coma of the system to permit correction of coma for each of the different conjugate object and image distances. As shown, Fig. 28, the lens V is relatively thin and close to the diaphragm 12 so that its astigmatic contribution is mainly a function of the lens power and almost independent of its shape. Also the spherical aberration changes slowly as a function of bending whereas the coma contribution changes rapidly with bending. Therefore by having a series of lens elements V on a turret 14, each element being of a different shape but all being of similar power, the appropriate one may be introduced into the system for a given magnification, or reduction. To correct for astigmatism the distance S 2  between elements II and III is varied such as by a lead screw 18, the other air spaces remaining constant. Optical data are given for the example shown.

Title: Electronic calendar watch
IPC: G04G5/00
Filed: 1976-11-02
Abstract: 1530525 Electronic watches DAINI SEIKOSHA KK 2 Nov 1976 [4 Nov 1975] 45512/76 Heading G3T In an electronic calendar watch Fig. 1, the capacity of a date counter 13, Figs. 2 and 3, is automatically changed according to the number of days in the month prevailing. For leap year setting switches Sa, Sb are manually operated to make it a 29-counter. In Fig. 3, the binary outputs of date counter 13 are fed to AND gates. When the date indication is 29, the output of AND 28 becomes "1". Similarly, when the date indication is 30, or 31 the output of AND gate 29 or 30 respectively becomes logic "1". At the end of the 31st day the output of NOR gate 31 becomes "1". A month counter 14 produces binary outputs QA-QD indicating the prevailing month. If for instance the month indication corresponds to a 30 day month the output of OR 42 will be "I"; then when the date indication is about to change from 30 to 31, the output of AND 30 will be "1". Consequently the AND gate 50 passes a "1" signal via OR 53 to the set terminal of the date counter 13 so that its output becomes 00001 and the date indication changes from 30 to 1. The counter 13 is likewise set to be consistent with 28-day and 31-day signals from the month counter 14. For leap year operation, when the month February is indicated, selective operation of switches Sa, Sb, Fig. 2 sets a flip-flop 44 to cause counter 13 to be set at the end of 29th day and in effect to function as a 29-counter. SETTING. (Fig. 2) A crystal controlled oscillator 7 and frequency divider 8 feed 1 Hz pulses to a seconds counter 9 to stop minutes, hours, date, month counters 11 to 14 respectively. Reset switch Sa, selection switch Sb, correction switch Sc are operable to set the time and date indication via a ring counter 22. To correct the hours for instance Sb is closed twice so that counter 22 output Q3 becomes logic "1". Switch Sc is then repeatedly closed so that AND gate 24 passes pulses via OR 16 to advance the hours counter 12.

Title: Aircraft altitude control system
IPC: G05D1/06
Filed: 1961-12-20
Abstract: 1,010,808. Automatic aircraft altitude control. SPERRY RAND CORPORATION. Dec. 20, 1961 [Jan. 6, 1961], No. 45606/61. Heading G3R. In an aircraft automatic pilot the pitch control channel is operable in three modes one without control of the elevators in dependence on altitude and the other two in which altitude or change of altitude signals are introduced only through an integrator. As shown,signals from the pitch pickoff of a gyro-vertical 40 on an aircraft are applied through a variable inductive device 34 to the elevator channel 14 of an automatic pilot to stabilize the pitch altitude. As long as altitude is not automatically controlled, signals from a radar altimeter 1 are, as shown, applied through an amplifier 6 to an integrating servomotor 10 which drives a potentiometer 12 the output of which is thus maintained equal to that of the altimeter so that the resultant signal from a summator 5 is zero. If at any altitude, a manually operated switch 3 is closed, relay operated contacts 4 a open so that, thereafter, deviations from the altitude at which switch 3 was closed produce signals from summator 5 which are applied to a further summator 25 which also now receives rate of change of altitude signals through a differentiator circuit 27 from a barometric altimeter 2. The combined altitude and rate of change of altitude signals are applied through a modulator 30 to a motor type integrator 31 which adjusts the rotor of induction device 34, and therefore the elevators, to correct the altitude. To avoid switching transients the altitude control system is not effective after closing switch 3 until operation of a delay relay 26 energizes a relay 18 to remove a short circuit from the output of amplifier 15. If a manually operated ganged switch 20 is moved to the other position signals dependent on altitude are derived through a resistor 42 from the barometric device 2 instead of from the radar altimeter. With this type of control closed contacts 20c render servomotor 10 effective to maintain the resultant output from the radar altimeter zero during altitude changes. In operating switch 20 from barometric to barometric plus radar control or vice versa contacts 20a open momentarily to reinitiate operation of delay relay 26 to short circuit the output of amplifier 15 for a period sufficient to avoid switching surge effects.
