Patent GB-198003-A (GB)
Abstract: 198,003. Joksch, R. Jan. 24, 1922. Tabular calculators. - A tabulated multiplication table, including all the products of a predetermined range of multiplication, is divided up into ten parts and the motion of two slotted or apertured bands moving at right angles to each other is utilized in such manner that, on setting the multiplier, all its products are positioned on one plane and on setting the multiplicand by means of the slotted bands, the final product is displayed at an aperture. Ten tabulating bands 5 marked with the products are arranged on rollers 2, 2a, which are all simultaneously rotated by the handle 3 on the gear wheel 25. If this handle is turned slightly so as to set the unit price, or multiplier, 2 the first band 5 shows along its upper portion parallel to the axis of the roller, the products 0, 2, 4, 6 - - 196, 198; the second band shows the products 200, 202 - - 398; and so on. For the multiplier 3 the first band would similarly show the products 0, 3, 6 - - 294, 297; the second band 300, 303 - - and so on. The two pairs of rollers 6, 6a carry bands having slots 7, 7a and these bands move at right angles one above the other so that an aperture 8 is formed where the slots cross. A handle 10<a> engages through a clutch an endless chain which, through gearing, moves the slot 7 parallel to the multiplicand scales 12. The handle 10<a> is for the units of the multiplicand and can move the slot 7 a tenth of the distance between the rollers 6. A similar handle 10 for the tens moves the slot 7 ten times as far as the handle 10<a>. A third handle 9 for the hundreds is connected by bevel gearing to the rollers 6<a> so as to operate the slot 7<a>. The multiplier being thus set by the handle 3 and the multiplicand by the handles 9, 10, 10<a> the final product is displayed at the aperture 8. In a modification, the tabulating bands are driven from the shaft 53, Fig. 9, by the wheel 54, chain 55 and a slide 57 having a finger 58 which moves over a scale to set the multiplier. The two slotted bands of Fig. 3 are replaced by slotted bands 27, 28 and a slotted plate 29. A slot 59 in band 27 corresponds to the hundreds (slot 7a in Fig. 3), this band being operated by lever 35 through shaft 34, gears 33 and bevel gears 31, 31<1> rotating the rollers 29<1>, 30. Slot 60 in band 28 corresponds to the tens, this band being operated from lever 43 by shaft 42, gear wheel 41 and wheel 40 which is rigid with roller 36 which is loose on shaft 32. The slotted plate 29 is moved by the toothed rack and sector 52, 51, wheel 49, link 48, wheels 47, 46, shaft 45, and lever 44. In the plate 29 the slots 61, 62 - - are arranged in ten columns, the width of each slot being one tenth the width of the slot 60.

Abstract: 721,568. Trolley-heads. WHITE, S. L. Aug. 6, 1952 [Aug. 15, 1951], No. 19823/52. Class 104 (3). The socketed boom-receiving portion 2 of a trolley-head has hingedly connected thereto a body portion 5 carrying the swivelling contactshoe member 8 with compression-spring means 10, 11 to resist the downward tilting movement of the portion 5, the boom-receiving portion 2 having an upwardly and rearwardly inclined formation 4 to deflect upwardly any obstruction and prevent its entry between the formation 4 and the contact-shoe member 8. The overhead wires are prevented from entering the opening between the two body portions 5, 2 when the portion 5 is deflected, by a guard 16 fixed at one end to the portion 5 and at the other end freely projecting beneath the top of the deflecting formation 4. A flexible cable 13 electrically connects the portions 5, 2. A guard member 14 connected at one end to the socketed portion 2 (and to the abutment member 11) underlies the hinge connection and the spring means 10, 11, 12 and extends upwardly close to the body portion 5. To apply the invention to an already existing trolley head, the head is divided adjacent the swivelling contact-shoe 8 and the rearward portion so formed has welded thereto wing lugs to receive a pivot pin inserted in the rear part of the front portion, and a lug to be connected to a compression spring supported on the front portion. The compression spring device shown in Fig. 2 is formed by a rod 20 provided with a spring abutment flange 21 attached to a cylindrical guide 22 slidably mounted on a cylinder 23 attached to a spring abutment disc 24 pressed against a rounded stop 25 on the end wall of a guard casing 26. The body portions 5a, 2a are electrically connected by two flexible connections 28. A loop 29 receives the pole for replacing a dewired head.

Abstract: 578,604. Gyroscopes. BENDIX AVIATION CORPORATION. Dec. 3, 1943, No. 20283. Convention date, Feb. 3. Addition to 573,710. [Class 97 (iii)] The gyro caging mechanism claimed in the parent Specification is how brought into operation automatically upon a predetermined tilt. As shown in Fig. 2, the caging pin 18 carried by the rotor casing 10 is electrically earthed and co-operates with a conductor ring 66 to initiate automatically (as described below) the vertical and rotary caging movement of the finger 41 when, for example, a supporting aircraft banks or pitches to a predetermined extent. In Fig. 7 is shown the caging circuit when the mechanism is in the caged position. To uncage the gyro, the pilot raises a knob 89 thus completing the circuit of a motor 71 by way of a battery 90, cbntacts 95, 87, 85, 79. The motor, operating through mechanism similar to that described in the parent Specification, lowers the finger 41 to uncage the gyro and also rotates a cam 80 to open motor contacts 79, 85 and close caging contacts 78, 82. If the craft now banks or pitches beyond a predetermined amount, the caging pin 18 touches the contact ring 66 and energizes a solenoid 69. The solenoid plunger moves an insulated block 88 and knob 89 to the caged position. The motor is also energized through contacts 84, 95, 78, 82 and effects the caging.
