Patent GB-1090763-A (GB)
Title: Calculator
IPC: G06F7/00
Filed: 1964-10-23
Abstract: 1,090,763. Electronic calculators; decimal points. FRIDEN Inc. Oct. 23, 1964 [Oct. 29, 1963], No. 15673/67. Divided out of 1,090,762. Heading G4A. An electronic keyboard-operated calculating machine as described in Specification 1,090,762 and comprising a magnetostrictive delay line for storing in interlaced manner six thirteen digit decimal numbers (plus sign) in pulse count notation form, an arithmetic unit including four counters and a cathode ray tube for displaying four of said numbers further includes a decimal point setting switch and logic circuitry whereby numbers, on entry, are automatically aligned with said predetermined decimal point position and the results of calculations (involving the four rules) are also similarly aligned. Before a calculation is started, the decimal point thumb wheel TW (Fig. 14) is set to the required number of decimal places (5 in Fig. 14). The thumb wheel is connected to a set of 4 stacked wafer switches (Fig. 3, not shown) comprising a signal generator I (Fig. 5) whereby predetermined ones of gates 120-123 are enabled so that, on energization of a line " DIV. SET ", a four stage binary counter comprising flipflops DPC1, DPC2, DPC4 and DPC8 is set to said number of places below the full count of 16 (i.e. 11 in the illustrated case). Following depression of the " decimal point " key during keying in of a number, the counter is steppedon one step for each subsequent digit key depression by pulses passing through gate 40a until a count of 16 is reached (counter equals zero) when gate 40a is closed and entry of further digits is prevented. In the event of the decimal point key not being depressed (i.e. whole number being entered) or a short decimal number being entered, the counter is stepped-on automatically or depression of the " enter " key. Fig. 14 shows two numbers 233 and 1À7 in decimal alignment and a further number 0À6 being entered. The operator has the choice of five settings of the thumb wheel TW giving respectively 0, 2, 5, 7 and 13 places of decimals. Procedures for dealing with decimal point alignment in multiplication and division are described (a further set of stacked wafer switches being provided for aligning the result of multiplication). The thumb wheel controls a still further set of stacked wafer switches for controlling the position of the decimal point in the CRT display (Figs. 7-9, not shown).

Patent GB-439242-A (GB)
Title: Improvements in, or relating to, release mechanism for electrical switchgear
IPC: H01H71/40
Filed: 1934-05-28
Abstract: 439,242. Automatic circuit-breakers. SCHIELE & BRUCHSALER-INDUSTRIEWERKE AKT.-GES., Baden-Baden, Germany, and CRABTREE & CO., Ltd., J. A., Lincoln Works, Walsall, Staffordshire. May 28, 1934, No. 15776. Convention date, May 26, 1933. [Class 38 (v)] Springs, arrangements of ; cases.-A compensated release system for motor-protection and other automatic switches comprises a series of thermally-sensitive releases which are coupled to, and adapted to operate a trip member, and a further thermal element not influenced by current-generated heat, but adapted to compensate for ambient temperature, the releases and compensator being mounted in separate chambers in an insulating housing whereby they are thermally and electrically insulated from one another. The thermal releases of a three-phase switch are mounted in compartments C of a casing A which contains a compartment D for the compensator. Each release comprises a ring- shaped bimetal strip E surrounding, and connected at one end to, a heating coil F, each strip acting on a member 8 passing through apertures P in the partitions B and into chamber D. Terminals G, H are connected to the free ends of the coil and strip respectively. The compensating strip 1 is similar to strips E and is mounted freely on a pivot 2 and carries at one end a crank-lever 3, which is urged by a spring 4 against a stop 5. The other end of the strip 1 carries the pivot 7 of a lever 6 having a pin-and-slot connection 6<a>, 9<b> with a releasesetting lever 9, which is mounted fast on pivot 2 and projects through a slot in casing D. Clockwise movement of 9 moves the lower end of 6 nearer to the member 8 and so lowers the tripping point, and 9 is prevented from being moved on the engagement of 6, 8 by passing the pivot 2 through a terminal 11 and placing a flat spring between the latter and a pin passed through the pivot 2. The action of the compensator strip is to produce, due to ambient temperature variations, movements of 6 corresponding to those of member 8. When 6, 8 engage, they cause separation of contacts 13, 14 and, simultaneously, the movement of the nose of 3 clear of catch 17 which is thereby moved by spring 4 to separate contact 16 from a contact 15. The contacts 14, 15 are connected to terminals 19, 20, respectively, and if 19 is connected in circuit with terminal 11 a momentary break of circuit is produced, whereupon 13, 14 re-engage, whereas if 20 is connected in circuit with 11, a permanent break is effected and reclosure must be effected by means of a handle connected to the pivot 18. Alternatively, a toggle or other mechanical trip may be operated by rotation of pivot 18. The Specification as open to inspection under Sect. 91 stated also that resetting of contacts 15, 16 might be effected by automatically tensioning spring 4 by the movement of a switch member, also that the coils F might each attract an armature rotatable on a pivot to operate the member 8 in the tripping direction. This subject-matter does not appear in the Specification as accepted.

Patent GB-1021567-A (GB)
Title: Improvements in or relating to change-speed power transmission control
IPC: F16H63/30
Filed: 1964-04-20
Abstract: 1,021,567. Change-speed control. INLAND TOOL & MANUFACTURING Inc. April 20, 1964 [April 30, 1963], No. 16253/64. Heading F2D. A manual change-speed control for motor vehicles comprises a guide bracket 10 bolted to the change-speed gear casing 11, a series of shifter elements such as 20, 22, 24 and a yoke 12 separately pivoted on the bracket by a pin 13, and a manual shift lever 14 pivoted to the yoke for cross-shift rocking by a pin 68 normal to the pin 13 and having a finger 90 selectively engageable with notches 92, 96, 98 for effecting gear-establishment. The gear controlled may have three, four or more forward speeds and one reverse. In the control for a four forward speed and one reverse gear shown, the shifter elements 20, 22, 24 are respectively connected by links 26, 34 and 20 to Reverse, 1-2, 3-4 striker arms 28, 32, 36, position detents (not shown) being associated with the shifter elements or shiftable parts of the gear. A Reverse balk plate 44 having a shallow notch 94 interposes the 1-2 and Reverse shifter elements 22, 20. The shift lever 14 has secured thereto, by a bolt 80, a squaresectioned member 18 which curves about the pin 13 and terminates in the finger 90. The square-sectioned member 18 is disposed in a rectangular slot 60 in the yoke 12 allowing limited cross-shift rocking of the shift lever. The pin 68 carried in the member 18 engages a vertical slot 70 in the yoke 12. The shift lever is biased into its 3-4 position by a spring connected to the bolt 80. In operation, in the neutral position only, the shift lever is rockable about the axis of the pin 68 for 3-4, 1-2 crossshift selection. For cross-shift to engage the finger 90 in the Reverse shifter element notch 92, in the neutral position only, it is necessary to lift the shift lever, the slot 70 accommodating this movement, in order that the finger 90 may pass through the balk plate notch 94 into the notch 92. In an alternative embodiment the notches 92, 94 are of the same depth as the notches 96, 98 and Reverse cross-shift balking is by a fixed pin fast on the yoke engaging a stop slidable in the shift lever. This stop is connected by a cable to a finger grip adjacent the shift lever knob so that it may be moved against a spring to clear the fixed pin and allow Reverse cross-shift. For a three forward speed and one reverse gear the element 20 is omitted and the space occupied by the element 20 and the balk plate 44 is filled by an arcuate plate. For more than four forward speeds further shifter elements may be provided.

Title: Improvements in or relating to direct current power supply devices
IPC: H02J7/12
Filed: 1958-05-22
Abstract: 860,780. Automatic voltage-control systems. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. May 22,1958 [May 28, 1957], No. 16492/58. Class 38 (4). In an automatic direct-voltage control system a transductor 3 has a winding 3a connected in series with an A.C. supply to a rectifier 2, a second winding 3b carrying the rectified current and a controlling winding 3c. The voltage V R  of a reference cell 15 is compared with a voltage V B , at a tapping 14 on a potentiometer 9-13 across a buffer battery 6, by a transistor T 1  and the resultant difference signal varies the base voltage of a transistor T 3 , controlling the current through control-winding 3c, so as to tend to maintain the battery voltage constant by varying the impedance of the transductor 3. The reference cell 15 is sealed and pressurized and has the same electrolyte as the buffer battery 6 near which it is installed. Over-charging of the buffer battery is prevented by making the resistance of a ballast resistor 8 equal to the battery voltage divided by the residual current through transductor winding 3b. A transistor T 2 , having a collector connected to that of transistor T 1 , compares a voltage across a resistor 7, carrying the output current, with a constant voltage across a semi-conducting diode 20 and varies the base voltage of transistor T 3  so as to limit the output current. The circuit elements enclosed by the broken lines are mounted as plug-in units.
