Patent GB-1276332-A (GB)
Title: Electrical switching devices
Inventor: ADAM IAN ROSS
IPC: H01H71/66
Filed: 1969-09-18
Abstract: 1276332 Switching systems for consuming devices MACLAREN CONTROLS Ltd 18 Sept 1969 46045/69 Heading H2H A switching circuit, for use with apparatus which switches itself on and off according to certain conditions, includes a bimetallic interrupting device which opens a pair of contacts when the load current ceases, and a control device which inhibits the action of the interrupter on receipt of a control signal. In the arrangement shown, an immersion heater 1 comprises an element 2 and a thermostatic switch 3 connected in series with contacts 4 and 5. The contact 4 is a resilient blade, and the contact 5 is a bimetallic strip. In use, the load current heats the strip 5 and the two contacts bend upwardly together, allowing a resilient bimetallic strip 7 to spring beneath the blade 4. When the switch 3 opens, the strip 5 cools and returns to its former position, leaving the blade 4 retained by the strip 7 so that no current can now flow in the load even when the switch 3 closes. The strip 7 may be displaced to an inoperable position either by a manual control 13 or by applying a control current to a heating coil 8. The arrangement may be used in an off-peak supply system to incorporate "one-shot" operation.

Title: Conditional variable incremental computer
IPC: G06F7/64
Filed: 1962-12-11
Abstract: 1,029,288. Digital calculating apparatus. GENERAL ELECTRIC CO. Dec. 11, 1962 [Dec. 13, 1961], No. 46798/62. Heading G4A. An increment computer (i.e. one which updates the previously computed values of functions of input variables from the observed changes in these variables) selects, in any given cycle of calculations, equal increments for all the variables. The size of the increments is chosen in accordance with the largest change in any one variable, and in the computer described is an integral power of two. In any cycle the increment chosen cannot differ from that of the previous cycle by a factor of more than two, so that if a step change from a steady state is applied to an input the increments will commence at 1 and advance in successive cycles to 2,4,8 . . . until the change is accumulated, when they will reduce again to enable the computed values to settle down to their new values. In the case of variables which have not changed, the increments will be added and subtracted in turn until the " settling down " phase is reached, so that all variables settle down together. The computer utilizes the same basic algorithm as that of Specification 945,773, enabling any of the four arithmetic operations to be carried out by the use of appropriate gating and control signals to the arithmetic units &c., and uses a magnetic drum for storage of data and instructions so that a single cycle of incrementation is carried out in one revolution. The layout of the computer is illustrated schematically.

Abstract: 1498700 Electronic timepieces TOKYO SHIBAURA ELECTRIC CO Ltd 20 Nov 1975 [21 Nov 1974 (2) 31 Jan 1975] 47758/75 Heading G3T In a setting/correcting arrangement for a digital electronic timepiece, a circuit generates a pulse train serving as a rapid correction signal when a setting switch is maintained closed for a period exceeding a predetermined interval, the pulse train being terminated when the switch is opened, and the circuit produces a single (1/32 sec) pulse upon each closure of the switch having a duration less than the predetermined interval. In Fig. 1, shift registers 2, 3, driven by 32 Hz clockpulses, detect the closing of setting switch 1, a NOR gate 7 producing a single 1/32 sec pulse which is applied via an OR gate 9 as a correction signal e.g. to the minutes counter (not shown) of the timepiece. Shift registers 4, 5, driven by 1 Hz pulses, detect when the switch has been held closed for longer than a predetermined interval, e.g. between 1 and 2 secs, the outputs of registers 3 and 5 opening an AND gate 8 to pass 8 Hz train of pulses through OR gate 9 to the minutes counter until the switch is opened. The resulting correction signal is shown in Fig. 31. Thus the time indication error may be initially reduced at a rapid rate and then the remaining error corrected one unit at a time by repeated operation of the switch. The predetermined interval may be extended by adding further shift register(s) as illustrated in Fig. 4 (not shown).

Patent GB-490811-A (GB)
Abstract: 490,811. Bomb dropping sights. SPERRY GYROSCOPE CO., Inc. Feb. 18, 1937, No. 4907. Convention date, Feb. 20, 1936. [Class 92 (ii)] Relates to apparatus for use with aircraft bombing sights which enables the release angle to be automatically set up when the apparatus is adjusted so that the line of sight is continuously maintained on the target. According to the invention, the line of sight is controlled by a variable-speed motor 50, the speed of which is adjusted by manually - controlled means 58 in accordance with the indications of a tachometer 56 driven by the motor and graduated in terms of data related to the time of fall of the bomb. The tachometer is shown graduated at 59 inversely as the height of the aircraft and is initially set by a gear 60 and pointer 62 to suit the terminal velocity of the bomb. The speed of the motor is adjusted by turning a knob 58 to adjust a contact 112 which is engaged by a governor-controlled contact 111 to short-circuit a resistance 114 in the armature circuit of the motor. The invention is shown applied to a gyroscopically-controlled bombing sight as described in Specification 449,238. The motor 50 drives a disc 51 forming part of a variable-speed gear, the driven cylinder 63 of which is geared to the pivoted sight prism 8 by shafts 96, 42, arm 135, sector 37 and rod 12. The radially-movable ball carriage 67 of the variable-speed gear is adjusted by a knob 65 so that the target is kept in view and the rotation thereby conveyed to a shaft 66 is the product of the ground speed and the time of fall, and is represented in Fig. 5 by Rw, from which the trail Y must be subtracted to determine the release angle #. The trail Y is obtained by rotating a shaft 70 by a knob 80 to set a pointer 78 to the correct air-speed curve on a drum 77 which is rotated by a knob 60<1> to suit the terminal velocity of the bomb. The shafts 66, 70 drive opposite sides of a differential gear 71, the planetary wheels of which drive a wheel 72 and arm 68 to set an electric contact 73 to the release angle. The bomb is released when this contact engages a contact 74 on a wheel 76 driven by the sightactuating shaft 42. A warning contact 901 lights a lamp 116 when the release angle is being approached. The prism 8 is adjustable for side-wind offset-angle by rotation in a fore- and-aft bearing 11 by means of a rod 13. The offset-angle is proportional to Y sin d where d is the drift angle. The slide 95 operating the rod 13 is moved proportionally to Y sin d by a crank 92 on a frame 87 rotated through the angle d by turning the drift knob 82, the crank radius being adjusted in accordance with Y by gearing 81, 91 connected with the shaft 70. British Specification 413,338 and U.S.A. Specification 1,783,769 also are referred to.
