Patent GB-161306-A (GB)
Title: Improvements in or relating to mechanical coding and decoding or ciphering apparatus
IPC: G09C1/08
Filed: 1920-01-13
Abstract: 161,306. Telling, H. G. Jan. 13, 1920. Codes.-Mechanical coding and de-coding or ciphering apparatus consists of a series of separate movable units, with which is combined a final syllable and mutilation-detecting and correcting unit. In the apparatus shown in Figs. 1 and 2, initial and intermediate units A, B are each furnished with biliteral groups in two series, vowel-consonant, and consonant-vowel, each series having associated a figure group from 0 0 to 9 9 all arranged so that at least a two-letter difference other than transpositions exists between code words. The final unit C bears biliteral groups only on the same plan, the final figure forming a stationary indicator as shown at C<1>. There are four possible combinations for the first letter of the initial and intermediate syllables as vowel or consonant, namely, VV, VC, CV, CC, and these, representing the basic formation of the code words are denoted by figures C, 1, 2, 3 respectively. Openings d, d<1>, d<2>, d<3>, d', d<5> in a combined indicator and guide D, Fig. 4, are arranged to shut off the separate series of the units A, B not required in the formation of a word. During the process of coding, the units not in use are locked against movement, but they can be released and all coupled together for checking and correcting purposes. As shown, the units are coupled separately and together through two shafts g<1>, g<2>, moved longitudinally by a worm E, the coupling being as follows :-A and C through gear-wheels G<3>, G<4>, G<20> (idle wheel), and G<5>, B being out of gear and locked by G<9> and a catch H engaging a hole in the side plate; B and C through gear wheels G', G<7>, G<21> (idle wheel), and G<10>, A being then cut of gear and locked by G" and catch H; A, Band C together through gears G<3>, G8, G<11>, G<20>, and G<5>,-G<6> and G<7> being still in mesh, and C-'2 meshing with G<21>: the catch H being freed from the frame at the end of the longitudinal movement of shafts g<1>, g<2>. In operation, the basic formation having been observed, the first figure of the group and the formation of tho first and second syllables are indicated through openings f<3>, f<4> by moving the slide D, this movement shutting off the series on A and B not required. Upon rotating A, C and B, C as required, the final syllable unit mechanically indicates the last figure and final syllable, and should an error have occurred mechanically detects it, and corrects it when all the units are rotated together in their freed position. The initial position of the units may be varied separately, and for secret coding the catch H may have various zero positions for setting the initial position of the units as a whole. Sliding shutters A<10>,B<10>, C<10> having openings facilitate reading off the groups. The separate series of biliteral groups on each unit A, B need not be moved together, thus giving two first syllable or two second syllable units.

In a preferred form, as shown in the Figure, a tube a adapted for attachment to an existing drier terminates in a cylindrical box b pivoted in side cheeks of the cylindrical main air chest d. The angular movement of the box b is limited by a pin thereon sliding in a groove in the side cheeks. The air discharge tubes e provided with cylindrical air boxes e<2> are pivoted in covers g around the main air chest. The upper ends only of the covers are fixed to the air chest, the lower ends being held in position by a spring ring h, whereby a good frictional contact with the air boxes e<2> results. Each part is provided with one or more apertures so positioned that as the tubes e are raised, the air supply is gradually cut off. Insulating plugs e<4> are provided for facilitating the adjustment of the tubes. The bottom d<1> of the cheat may be perforated to coact with a pivoted perforated disc for the escape of air therethrough. If desired, the joint between the tubes and main air chest may be of the ball- and-socket type. In a modification, the air supply may be made independent of the position of the tubes by the use of valves in the tubes or air chest. If desired, the device may be made a single unit with the blower and heating elements.

Abstract: 394,045. Control of motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Eaton, J. ; Rosendale Road, Schenectady, New York, U.S.A.) Jan. 20, 1932, No. 1775. Convention date, Jan. 20, 1931. [Class 38 (iii).] An elevator motor 12 is controlled bv resistances 132 .. 136 in circuit with the field of a Ward-Leonard generator 13, the resistance being controlled by levelling and main controllers 28, 30 driven conjointly through a differential gear 26 by the elevator motor 12 and an auxiliary motor 33 which is started by a car switch 70 and stopped by floor finder 34 and floor selector 53 driven by the auxiliary motor and co-operating with floor switches 47 .. 51. This control ensures that the acceleration and running speed are governed by the auxiliary motor 33 and are thus independent of the load on the elevator motor 33, and that after stopping the auxiliary motor 33, the controllers 28, 30 are returned to their " off " position by the main motor in accordance with the distance the car is from the floor. Final levelling is effected by oscillatory valve devices 56, 57 causing relays 58, 59 to pick up when the valves cease to oscillate due to co-operation of the oscillatory circuits with screens located in the hatchway. This levelling system is similar to that described in Specification 316,193, [Class 38 (iii), Electric motor control systems &c.]. A correcting motor 32 can operate automatically when the elevator 'is at rest to adjust the relation of the controllers 28, 30 to the motor 12 so as to compensate for stretch of elevator cable &c. One of a series of lamps 211 is illuminated to indicate the floor at which a stop is to be made. The lamp is illuminated as soon as deceleration of the car commences and is extinguished when the car comes to rest.
