IPC: B60Q1/56
Filed: 1924-08-20
Abstract: 242,014. Dawson, L. H. Aug. 20, 1924. Controlling consuming devices. - A vehicle identification plate comprises an electrically illuminated box-form sign which is switched on when one or more of the headlamps or sidelamps are switched on but which can only be switched off by means of a switch at the rear of the vehicle inaccessible to the occupants thereof. The battery B, Fig. 5, and the head or side lamp 9 are connected by two alternative circuits containing a drum switch 16, Fig. 3, carrying a bridge-piece 12. To switch on the lamp 9 the switch 9<a> is closed, the bridge-piece 12 being, as shown, in the upper circuit. The solenoid 10 is thus energized and draws downwards its armature 13 to which is attached a pivoted slotted bar 14 which as it moves down carries with it a stud 14<a> on the drum 16 and rotates the drum until a spring 17 attached thereto moves across the axis of the drum and draws the slotted bar into the full-line position. The bridge-piece 12 now breaks the upper and closes the lower circuit 21 thus keeping the lamp 9 illuminated and allowing the current to pass through the lamp circuit of the number-plate 3, which is then unaffected by manipulation of the switch 9<a> and remains illuminated until the drum is turned back to its original position by means of a hand-operated knob on the drum. Specification 134,291 is referred to.

Title: Improvements in prepayment mechanism for gas and like meters
IPC: G07F15/04
Filed: 1933-07-20
Abstract: 412,425. Prepayment mechanism for meters. WILSON GASMETERS, Ltd., G., Foleshill Road, Coventry, WILSON, J. H., Mill House, POOLE, D. C. E., The Elms, both in Baginton, near Coventry, and ORMEROD, G. A., 24, Ash Tree Avenue, Coventry. July 20, 1933, No. 20440. [Class 27.] In prepayment mechanism for gas, electricity and like meters of the kind adapted for operation by coins of more than one denomination and comprising two coin or measuring wheels 2, 3 and a coin holder 14, the inlet valve, switch &c. is operated by an axially displaceable member 4<a> common to both wheels and operated directly by one of the wheels by a coin of one size and differentially by both wheels by a coin of another size. The wheel 2 is carried by a sleeve 2<a> fitted with a stud 2b which engages a screwthread on a spindle 4 extending from the member 4<a>. The wheel 3 rides on the sleeve 2<a> and carries a pinion 3<a> which through sun- and-planet reduction gearing 5, 6, 8 rotates a sleeve having an inward projecting pin 8<a> slidable in a slot 4b extending the length of the spindle 4. Insertion of a small coin through the slot 16<a> in the price change plate 16 depresses a slide 15 carrying a pin 15<a> extending through a vertical slot 14<a> in the side of the holder 14 and through a cam-shaped slot 12b in a tooth 12 pivoted at 12<a>, and tilts the tooth into engagement with the wheel 2. Insertion of a large coin depresses a vertically sliding tooth 13b into engagement with both wheels 2, 3 and pushes the pin 15<a> further down to bring the tooth 12 back out of mesh with the wheel 2. Rotation of the coin-holder 14 by a knob 11<a> when the tooth 12 is in engagement turns the stud 2b and advances the member 4<a>, by reason of the thread on spindle 4, a given amount. When a larger coin, of smaller value, brings the tooth 13b into engagement with both wheels 2, 3 the stud 2b advances the member 4<a> as before, and the pin 8<a> simultaneously turns the spindle 4 round in a direction to reverse the outward movement of the member 4<a>, and by a differential effect leave a net advance equivalent to the value of the larger coin. A spring 18 assists in the return motion of the spindle 4 under the action of a worm 10 driven by the meter mechanism and reversing the wheel 2, the wheel 3 being held against back motion by a spring pawl.

Class 146(3) An inkholder, especially for laundry marking-ink, comprises a container., in which is a float having a dipping cup communicating only with the upper surface of the float. As shown a float 8, weighted at 8d is arranged in a container 6 having a raised base 6a to displace some air from the float so that temperature rises do not cause the contained air to bubble out; the float top 8b is convex to permit ink to drain therefrom, and is recessed at 8a to form the dipping cup; the open bottom enables the float to act as an ink trap if the inkholder is overturned; the screwon cover 9 has a safety funnel 9a and a float stop 9b. In another form the fioat .is of squat form, with a flat or -convex closed bottom, and the container base is correspondingly shaped to minimize the dead space; the top edge of the funnel 9a is enlarged to the full cover width and its lower rim, slightly larger than the dipping cup 8a, acts as a float stop. In a further form a closed-bottomed float has a small wall round the edge of its flat top to form a shallow dish with the dipping cup at its centre; ribs attached to the float sides, to keep it spaced from the container walls, are extended upwards to support a shallow funnel-shaped guard ring which minimizes exposure of the ink in the'dish, the cover .9 in this case having a safety aperture 9a of much larger diameter and less depth. The float and container may be cylindrical or polygonal in plan, and the dipping cup 8a may be hemispherical; spacing ribs may be provided on the interior of the container walls.

Abstract: 1,103,186. Printer-control circuits. FUJITSU Ltd. 14 May, 1965 [14 May, 1964], No. 20600/65. Heading G4H. A line of characters is entered in store BM, Fig. 4, and is repeatedly read out character by character as print cylinder TW rotates. A device S generates a signal representing the character type on cylinder TW which is currently in the printing position and this is compared at CO with each character in the line to be printed read out from BM. If a character from BM is identified as that currently in the printing position, the corresponding stage in register OP-REG is set, this register having as many stages as there are character positions in a line. At the same time, a corresponding stage of register FBM is set to indicate that a character is about to be printed in that position. At the end of a line read-out from BM, device S produces a signal to operate those print hammers HM associated with set stages of register OP-REG and to reset OP-REG. The process is repeated for successive characters on cylinder TW until all stages of FBM have been set, whereupon a signal PRED is developed to indicate that a complete line has been printed. This ends the print cycle and causes the paper advancing mechanism to be actuated. Since the signal PRED may occur before a complete revolution of TW has taken place, the effective speed of the printer may be increased.
