Title: Chiming and striking means for electric and ordinary clocks
IPC: G04B21/02
Filed: 1932-04-08
Abstract: 397,955. Striking and chiming mechanism. WILSON, H., 17, Bradshaw Street, Moss Side, Manchester. April 8, 1932, Nos. 10052 and 16250. [Class 139.] The invention comprises a striking and chiming mechanism adapted to be used with any clock and driven thereby. The striking mechanism comprises a toothed rack R, Figs. 1 and 3, pivoted at Z<1> and raised by a snail cam S mounted on shaft A rotated hourly by the clock. The rack carries a wheel train including a pinion Wand ending in a fly F, the shaft of which has locking projections F<1>, F<2>. Pinion W meshes with a stationary rack V whereby the fly is driven during the fall of the rack, a ratchet being inserted in the train to prevent operation of the fly when the rack is raised. The amount of fall of the rack R is controlled by a lever C, sprung into engagement with the twelve-hour snail T geared to shaft A, the end C<2> thereof engaging and rocking the arm X<2> of a pivoted lever X<1> against the bias of a spring to release a sprung lever X which rocks and locks the fly by engaging the stop F<2> thereof. The fly and its train remain locked while the rack is raised being released by the end V<1> of the stationary rack V engaging and returning lever X as the rack reaches its highest position. The hammer H is actuated during descent of the rack by each rack tooth through a sprung pawl N. In an alternative construction the rack R, Fig. 4, carries a pawl el adapted to coact with a pin P<1> on the snail S to render the release time of rack R more definite. The twelve hour snail T is concentric with S and the arm C coacting therewith is mounted on R. The fly is dispensed with, the fall of the rack being controlled by an air dashpot device ab. The chiming mechanism comprises a pinned barrel B freely mounted on shaft A, geared to a fly f by a wheel train b<1>, and normally locked by a pin Y engaging one of the notches in the 4/4 disc Q rigid therewith, and by another pin Y<1> engaging a notched wheel U in the train. Pins Y, Y<1> are carried by the locking lever L pivoted at L<1> which is lifted at the quarters to release disc Q by a lever I rocked by the quarter pins on a disc K rigid with shaft A. The barrel B is driven by a spring E, recessed therein, continuously wound by shaft A. A rigid wire W<1> fixed to the locking lever L engages the projection F<1> on the shaft of the strike fly during chiming to prevent operation of the striking mechanism until the chiming mechanism has been locked.

In a tumbler drier comprising rotatable drum 5 in substantially air-tight cabinet 2 maintained at superatmospheric pressure, hot air is forced through perforation 14 into the drum and exhausted therefrom into hollow door 3 and conduit 20, substantially none of the exhausted air from the drum passing back into the cabinet owing to the small air gap 16 between the drum end wall and cabinet wall 22. The cabinet 2 is supplied with air by fan 9 drawing in air from the atmosphere. The drier comprises a reversible motor 8. The fan 9 is mounted on one side of the motor driving shaft 10 and is operated irrespective of the direction of rotation of the shaft. On the other side of the shaft is mounted a bidirectional clutch (not shown) such that when the motor shaft 10 rotates in one direction the clutch is rotated and hence the pulley 11, belt 12 and drum 5 are rotated. When the shaft rotates in the other direction the clutch slips and the drum remains stationary. The drier is provided with a lint gauze in the hollow door 3. The heaters may be gas heaters or spiral electric elements. The wall of the drum 5 may be formed with paddles on its inner surface. The motor and heaters may be automatically shut off when the door is opened.

Filed: 1942-07-20
Abstract: 583,797. Order telegraph signalling. MAcTAGGART, SCOTT, & CO., Ltd., and PRENTER, R. G. July 20, 1942, No. 10119. [Class 118 (ii)] [Also in Group XXIX] Hydraulic remote control or power transmission apparatus comprises a pair of hydraulic transmission cylinders and rams connected by piping with a similar receiver, and a hand wheel operating the transmitter, e.g. to transmit ships' signals, a byepass valve being provided to place both sides of the apparatus in communication with a replenishing tank, the valve being opened only when the hand-wheel is returned to mid-position and after it has been brought to rest. The transmitter comprises a casing 1 forming a replenishing vessel and having three parallel cylinders, in the outer ones of which work rams 5 and in the middle one a plunger valve 11. As shown, the rams are operated through a hand wheel 28 and cams 29, 31 which act on one or other ram according to the direction of rotation through spring pressed pivotal extensions 6, Fig. 5, carrying rollers, one of the extensions being held upright while the other is folded about its pivot into an inoperative position. The rams carry collars 8 which are pressed upwards by springs 10 to effect the return strokes. The valve .11 is also operated by a cam 30 on the hand wheel shaft and in the midships position of the handle opens communication through passages 24, 25 between the valve cylinder 3 and the ram cylinder, the valve cylinder having a communication through a needle valve and a filter with the replenishing liquid. The needle valve allows an equalizing flow only after the handle has been brought to rest with the valve 11 in open position. The hand wheel operates a pointer 33 through bevel gearing. A full turn of the handle must be made before reversal is possible, and this is ensured by a toothed wheel 35 with a gap in its periphery and a spring centred detent 36 acting as a two-way ratchet. The receiver comprises a pair of ratchet wheels and a star wheel on the same shaft. The ratchet wheels are actuated by trigger bars operated from the pipe lines and are returned by springs. The star wheel co-operates with a roller on a spring-urged lever to ensure a full stroke ; the shaft actuates a pointer and a pair of gongs of different tones selected in accordance with the sense of rotation of the shaft. Specification 561,939 is referred to.

Title: A coded communication system
IPC: H04N1/413
Filed: 1970-03-05
Abstract: 1292682 Facsimile systems ELECTRONIC IMAGE SYSTEMS CORP 5 March 1970 [13 March 1969]. 10743/70 Headings H4F and H4P In facsimile transmission where binary signals generated by a horizontal scan of a document are run-length encoded in fixed length binary words, the first binary word of a scan sequence, which usually corresponds to the LHS margin, is of a lower length than the subsequent code words corresponding to the information content of the document, the first word being long enough to code a blank line minus one binary signal, no run-length code being transmitted for a wholly blank line only the line-prefix synchronization signal. Optionally the scanning mechanism can be preset to the LH edge of the information area, so obviating the long first binary code word for the margin, and terminated at the RH edge. The rate of scanning horizontally and/or vertically can be varied to provide a regular rate of transmission of run-length code words. In Fig. 4 a clock generator 76 drives the counters 77 and 78 to control via digital/analogue converters 79 the horizontal and vertical position of a photo-electric scanner 71. The video signal is generated, is sampled and quantized (81) to generate binary signals having one of two levels according to the black and white content of the document, which are passed to a line store 86. Upon the first edge detector 83 sensing the first transition in the level of the binary signal for a horizontal scan, corresponding to the start of scanning of the information on the document, the first edge detector opens gate 88 to pass the reading of the horizontal counter 77 to a first edge buffer store 89 and output register 73. A last edge buffer receives the counter 77 reading at each binary level transition, so when clock generator 76 signals the end of a line scan the buffer contains the position of the LH edge of the information. As the scanner returns to the start position, address and readout control 93 passes the signals stored between the first and last edge positions in line store 86 to runlength coder (96). The run-length codes are stored in the output register and transmitted after the long code word defining the margin and a prefix line synchronization signal supplied to the output register from clock generator 76 at the start of the line scan. In an alternative embodiment (Fig. 1, not shown) the binary signals are run-length coded as they are generated and the code words passed to an output register whose capacity is less than a line of code words, so necessitating variation in the scanning rate. A border control circuit (Fig. 2, not shown) may preset counters 77 and 78 and disable the first edge detector 83. At the facsimile receiver (Fig. 3, not shown) the detection of a synchronization pulse returns the scanning facsimile printer to its home position from which it moves to a start position according to the long binary word defining the margin. Thereafter the receiver prints according to the binary run-length encoded words.
