Title: Improvements in prepayment mechanism for meters
IPC: G07F1/00
Filed: 1938-04-05
Abstract: 510,978. Prepayment mechanism for meters. ENGLISH ELECTRIC CO., Ltd., TILSTONE, G., and DONELLY, J. F. April 5, 1938, No. 10448. [Class 27] Coin-discharging mechanism; returning coin.- An incorrect coin is discharged or returned merely by return movement of the operating handle to its initial position after a forward movement up to the position at which crediting normally commences. The invention is shown applied to the mechanism of Specification 498,306 wherein rotation of an operating shaft 2 first gauges a coin in a pocket 14, then establishes an appropriate credit, and finally displaces a slide 18 to discharge the coin. A disc 4 is secured to shaft 2 and has a projection 20 which rocks a bell crank 11 connected with the slide 18 to discharge the coin at the end of the crediting movement. A pawl 15 pivoted at 15a to the disc 4 is urged against a stop 17 by a spring 16 and slips past the bell-crank 11 during the initial coin-gauging movement of shaft 2. If the coin is incorrect, the shaft 2 is arrested at the end of this initial movement and by turning it back to its initial position the pawl 15 rocks the bell-crank 11 to discharge the incorrect coin. The disc 4 has ratchet teeth engaged by a full-stroke pawl 5 only during the crediting part of the movement so that the shaft 2 can be turned backwards and forwards freely over the initial part of its stroke. A slipping clutch is incorporated in the operating handle to prevent damage when the operating shaft is arrested.

Title: Tape feeding and severing mechanism for laundry-tag marking machines
IPC: B41K3/42
Filed: 1950-05-01
Abstract: 672,435. Typewriters &c. BRAUN, P. N. May 1, 1950, No. 10651/50. Class 100 (iv). For marking machines for printing on a tape and the production of laundry-tags, having a platen, on which the tape is placed, movable toward and from the type carrying members, a tape feeding and severing mechanism mounted on the platen carrier includes a supply holder for the blank tape, whose end portion is trained to extend across the platen, means to feed the tape as the carrier moves away from the printing line, and a knife movable successively to the feeding means to sever the printed portion of the tape. The platen 4, Fig. 3, is supported on a carrier on an arm 3, Figs. 3 and 8, and is movable by a handle 18 towards and away from printing position in contact with type wheels 1. Ink-ribbon mechanism 7 is provided, including a flexible guide 8. Blank tape 16 from a supply reel 20 on the platen carrier is fed transversely across the platen by means of a star wheel 28, Figs. 8 and 12, driven by a pawl 32 mounted on the machine frame. The wheel 28 drives a serrated wheel 25, against which the tape is pressed by a roller 24 on an arm 21 biassed by a spring 27. The star wheel is borne in the base plate 11 of the platen carrier. When the platen is moved towards the type wheels, the star wheel moves the pawl out of operative position, a weighted end 35 of the pawl thereafter restoring it to operative position to drive the star wheel as the platen begins to be withdrawn. On further withdrawal, a knife 40 severs the printed part of the tape. The knife 40 is pivoted at 41 to the platen carrier, and has a shearing edge 42. As the platen is moved towards the type wheels a stud 47 on a lever 45 pivoted at 46 swings the knife to a horizontal position, the lever 45 also swinging clockwise in Fig. 3 until stopped by a pin 49. On withdrawal of the platen, the knife is first allowed to swing to an oblique position by the weight of its aim 43, which passes into the space between the stud 47 and a second stud 48 on the lever 45, and is then swung to the position of Fig. 3 by the stud 48 to sever the tape. The tape passing the platen is supported in grooves 14, 15 in plates 11, 13 of the platen carrier.

Title: Trench excavator
IPC: E02F3/18
Filed: 1943-07-01
Abstract: 565,914. Trench diggers. HENDERSON, W. M. July 1, 1943, No. 10681. [Class 6 (i)] Trenches are excavated by a rotary implement 20 associated with means for depositing the displaced material in advance of the implement, and further means for moving the material to one side of the line of travel of the implement. The apparatus is coupled at its forward end to a tractor or the like 26 having lifting and sustaining gear and driving gearing 25 for the various members. The rotor 20 is formed with radial blades 24 rotating in the opposite direction to the wheels of the tractor &c., thus lifting a slice of soil which is pushed forwardly by the scraper 38 and then diverted by the arm 43. The power take-off shaft 25 transmits movement through a crank-shaft 28, crank 31 and connecting rods 32 to a pair of arms 29, each with a pawl 30 effecting intermittent movement of the rotor 20. The scraper 38 and the arm 43 also derive their movement from the arms 29, the scraper being mounted on arms 39 pivoted directly to the arms 29 and the arm 43 connected through the linkwork 45, 47, 46, 48, 44. Forward movement of the apparatus is provided by the winding up of a winch 34, the cable 37 from which is attached to a point ahead in the line of travel. Another winch 50 acting on the main frame 27 of the implement regulates working depth and lifts the implement clear of the ground when necessary.

Title: Improvement in and relating to noise suppression in radio receivers
IPC: H03G11/00
Filed: 1945-04-30
Abstract: 639,184. Radio receiving circuits. MURPHY RADIO, Ltd., and HAWKINS, G. F. April 30, 1945, Nos. 10876/45 and 8240/46. [Class 40 (v)] Undesired signals of short duration are suppressed by including in a signal channel a one-way conductor, e.g. a diode, so set that signals due to increase of carrier reduce the current through it, through which conductor the signals influence the potential of the input terminal of the next stage, said input terminal being included with a D.C. source in a circuit of such time constant that the rate of change of the potential of the terminal in the direction in which unwanted signals tend to change it cannot much exceed the rate necessary for transmission of the highest wanted frequency. In Fig. 1 a diode 6 is connected between the anode of an audio amplifier 1 and the input terminal 3 for the next stage, which terminal is included in a time constant circuit 4, 5 connected to H.T.+. For normal signals or zero signal, diode 6 is conducting, and the time constant of 4, 5 is chosen so that point 3 can follow the highest frequency of the wanted signals which are thus passed to the next stage. On the occurrence of an interference peak diode 6 is cut off, and the potential of point 3 rises slowly as condenser 5 is charged through resistance 4. At the end of the interference peak diode 6 conducts and quickly discharges condenser 5 through valve 1. By this means, during the short period of interference, the potential of point 3 rises only a very small amount. In the above circuit the time constant of circuit 4, 5 has been made short enough to allow for the greatest amplitude and highest frequency of desired signals. For signals of lesser amplitude and lower frequency, the time constant is desirably longer, so that the interference peaks produce less effect on point 3. This is effected in the arrangement shown in Fig. 5. The time constant circuit 4, 5 is fed from the anode of succeeding amplifier 9 after rectification at 12 and smoothing at 15. Also an inductance 17 is included in the anode lead of valve 9. Thus the D.C. voltage fed to 4, 5 and hence the time constant, vary according to the amplitude and frequency of the received signal. In a further modification, Fig. 6 (not shown), the voltage fed to 4, 5 is derived from a leaky grid detector fed from the anode of valve 9 through a frequency sensitive network. Specifications 532,521 and 639,183 are referred to.
