Abstract: 1,229,624. Counting-apparatus. A. O. SMITH CORP. 10 May, 1968 [24 May, 1967], No. 22366/68. Heading G4D. A preset counter for use with a fuel-dispensing apparatus has its transfer mechanism uncoupled when dispensing is complete. Before a dispensing operation a control ring 7 in the base of the counter has a cam (52) (Fig. 5, not shown) underlying a rod 50 so as to maintain a comb 46 in raised position, and therefore a set of tens transfer pawls 43 in inoperative position. In this condition the numeral wheels can be preset individually by push rods 4. Each operation of a rod 4 causes its associated pawl 57 to rock counter-clockwise so that its tip 59 engages ratchet wheel 27 to step the associated numeral wheel. When the counter is set to the required value the flow valve is opened, turning the control ring 7 to the position shown in Fig. 2 and so enabling the transfer mechanism. The flowmeter drives the counter subtractively via 15, 22, 23, 24, 25, spring-pressed pawls 29 and internal ratchet 28 on the units wheel. A cam 38 lifts a follower 42 which falls at transfer, Fig. 4, so that spring-pressed pawl 43 drives the ratchet wheel 27 of higher order. When all the higher order wheels have been returned to zero the comb 46 meets flats on cams 61 and falls, so permitting a units feeler 37, Fig. 3, to fall momentarily. The oscillation of the feeler 37 allows the control ring 7 to make one step counter-clockwise before being caught again by latch 75. The ring 7 acts through rod 8 to half-shut the flow-valve. When the units wheel also returns to zero feeler 37 falls into notch 36 and the control ring 7 makes a further step to shut the valve and disable the transfer mechanism again. Flow can be stopped in an emergency by pushing rod 6 which acts through lever 84 to disable latch 75 and return control ring 7 to stop position. A total meter is provided.

A method of making panti-hose comprises providing planar forms 1 and 2 having perpendicular side pieces 15, 16 and on the opposite opposing sides U-members 11, 12, the forms being movable to and from each other on a bar 9 and each adapted to receive thereover a respective elongate stocking, a plate 23 covered with adhesive moving between the U-members when the stockings are in position such that subsequent inward movement of the forms provides a pattern of two parallel lines of adhesive on each stocking, the plate 23 then moving away to allow the forms to come together again to stick the stockings and finally a hot wire moving between the legs of the U-members 11, 12 to cut away the fabric therebetween. The open end of each U-member is divergent at 14 so that extra fabric is cut away at the top of each stocking to form the waist of the garment. The plate 23 may be mounted on a rod 24 which reciprocates to allow the plate to move into and out of a receptacle of adhesive below the forms. In a modification the forms are cylindrical and fixed in relation to one another with the U-members 11, 12 movable into and out of the cylinders.

Abstract: 1,251,307. Facsimile transmission system. XEROX CORP. 22 Dec., 1969 [23 Dec., 1968], No. 62307/69. Heading H4K. A facsimile transceiver is coupled to a data modem attached to a telephone line by means of a logic circuit which includes a timing device for cutting-off the data modem as soon as the transmission of a facsimile signal has ceased. Cessation of the signal may occur in respect of an incoming transmission or an outgoing transmission or a lack of e.g. paper in the transceiver which effectively prevents further reception. Operation, automatic.-An operator places the data modem (not shown) in its data mode and closes switch 14 thus connecting input a of NAND gate 10 to ground i.e. logic 0. Provided paper is available in the facsimile transceiver (not shown), logic 1 appears on lead " Paper " so that " O " appears on the b input of NAND gate 30. The consequential " 1 " outputs of gates 10 and 30 together with the " 1 " output of inoperative manual switch 18 cause NAND gate 12 to produce a " 0 " output which is effective to light Auto lamp 16 and to bring-up relay K1. The latter indicates to the data modem over lead " Ready " that the system is ready for a facsimile transmission. In the case of an incoming call, a " 1 " appears on lead " Interlock " from the data modem whereby input c of NAND gate 92 is also marked with a " 1 ". The input a of gate 92 is already at " 1 " and its input b will receive " 1 " from NAND gate 40 provided there is no incoming facsimile signal i.e. " 0 " on the " Carrier Detect " lead. Consequently the " 0 " output of gate 92 turns on timer 90 which, if it times-out in say 30 secs., operates relay K2 and thus causes the data modem to hang-up. If, however, a facsimile signal does appear, the output of gate 40 changes to " 0 " and via gate 92 resets the timer. The continuation of the lead " Carrier detect " past inverters 50, 60 is effective to control the transceiver. If the transceiver runs out of paper, the resultant " 0 " on lead " Paper " is immediately passed via gate 40 so as to restart the time-out period and thus hang-up the data modem. In this case, relay Kl is also dropped via gates 30, 12 so as to prevent the data modem being seized again. In the case of an outgoing call a similar sequence of events takes place but release of the connection is controlled by the appearance of " O " on the " Paper " lead so that only one automatic send operation is allowed due to the release of K1. In the manual mode, the switch 18 is closed so that NAND gate 12 cannot activate K1.
