Title: An improved time limit meter and indicator for use in respect of car parking
IPC: G07F17/24
Filed: 1938-02-01
Abstract: 499,614. Prepayment timing meter for parking vehicles. PARKING METERS, Ltd. Feb. 1, 1938, No. 3081. Convention date, Feb. 3, 1937. [Class 27] A car parking time meter comprises a casing 10, Figs. 3 and 4, in which a vertical rod 18 of square section is slidably mounted in brackets 17 and has at its upper end a bar 19 carrying indicator discs 20 which show through glazed apertures 13 in the front and rear walls of the casing when the rod is raised. The rod is raised by rotating a shaft 25 carrying a segmental cam 26 engaging a slot 24 in the rod, which is then held in its raised position by a spring detent 22 engaging a notch 21. The forward rotation of the shaft 25 winds a cord 29 on a drum 28 and tensions a spring 31, so that the shaft 25 is slowly rotated in the reverse direction by the spring 31, a clockwork mechanism being provided in known manner to control the speed of the return rotation. At the end of the time allowed for parking, the cam 26 disengages the detent 22 and the rod 18 drops to remove the discs 20 from the windows 13. The shaft 25 is rotated in the forward direction by a shaft 32 having an outside handle working between two fixed stops 39 which limit the movement to half a revolution, the shaft 32 also having a collar 34 with two axially projecting pins 36 which engage a transverse pin 37 passing through the shaft 25. Actuation of the shaft 32 is prevented until a coin is inserted through a slot 14. Coin action, weight.-The coin drops to a holder 40 on one end of a pivoted lever counterbalanced by a weight 45. The lever is thereby tilted to withdraw a detent finger 47 from the push of a pin 49 projecting from the shaft 32. The pin 49 during the turning of the shaft 32 moves aside a spring 41 to withdraw a pin from the coin holder 40 and allow the coin to drop.

Title: Loop spreaders for sewing machines
IPC: D05B61/00
Filed: 1929-01-30
Abstract: 318,459. Fairweather, W., (Singer Manufacturing Co.). Jan. 30, 1929. Chain stitching and double-loop stitching.-In a straw-braid sewing-machine of the general type described in Specification 160,920, in which a straight eyed-needle and a straight hook-needle co-operate with loopers, a loop-spreader is provided for engaging the loop on the hook-needle, to prevent dropping of stitches. The needle-bar 7 has an offset head 8 carrying the eyed-needle 9 and the hook-needle 10. The needles co-operate with loopers 11, 12 in the usual way to form the stitches. The needle-bar is actuated by the linkconnection 13 with the slide-block 14 in the fork of the lever 15 pivoted at 16 to the bed 1. The lever 15 is rocked by the pitman 17 from the eccentric 18 on the main shaft 19. The position of the block 14 in the fork of the lever 15 is controlled by the thickness of the work under the presser-foot 3 as described in Specification 160,920 so that the needles rise to a constant height above the upper surface of the work regardless of the variations in work thickness. When the needles are above the work, the looper mechanism seizes a thread-loop from the eyedneedle 9 and deposits it in the barb of the hookneedle 10 and as the needles descend, the needle 10 draws the loop through the work. As the work is fed, the sides of the loop are carried over the eyed-needle which enters the loop in its next ascent. To make sure the needle 9 enters such loop, a spreader 20 is provided. This spreader is in the form of a flat blade with a V-shaped point 21 between the needles and the blade 20 transverse to the plane of the needles. The sides of the loop straddle the spreader and open the loop for entry of the eyed needle, Figs. 13 and 15. The spreader shank is adjustably mounted in a slot in a carrier 23 pivoted on a pin 24 fixed to lugs 25 in the bed cover plate 5. An arm 27 engages a slot to the carrier. The lower end 28 of the arm extends between rollers 29 on the needle-bar head 8. This causes the spreader to be swung upwardly on movement of the needles, to spread the loop.

Filed: 1947-02-04
Abstract: 666,680. Magnetrons. WESTERN ELECTRIC CO., Inc. Feb. 4, 1947 [Sept. 19, 1945], No. 3290/47. Class 39 (i). An electron emitter in a magnetron comprises a solid metal rod 26 coated at 19 with electron-emissive material and heated by conduction from a heater element 30. The cathode rod 26 is positioned within a copper block anode 10, brazed to steel polepieces 13, 14, the anode having multicavities 11 for tuning and end spaces 12. The rod 26 is of molybdenum, steel, nickel or nickel alloy, formed with rings 28 to limit the field of electron flow; and the electron emissive material is preferably a mixture of barium, strontium or calcium oxide with nickel powder. At one end the rod 26 is extended to assist heat dissipation and the other end is enlarged and recessed to accommodate the element 30. This element is of tungsten with a coating of aluminium oxide. The whole cathode assembly is carried by a tubular support 33 of low expansion metal, " Kovar " (Registered Trade Mark), to reduce displacement of the cathode. The heater is energized through a rod 32, also of " Kovar," and the support 33; alternatively, Fig. 2 (not shown), twin heaters on either side of the anode may be energized in series through rods 32. A " Kovar " sleeve 23 unites the polepiece 14 and a hard glass insulating seal 24. In a modification, Fig. 5, flanged rings 59 are shrunk on to a tungsten cathode rod 51 and, to reduce heat loss, a molybdenum shield 52 encloses the heater 53, which encircles the rod and is embedded in insulating material. In this case the electron emissive coating 29 is applied so that it is flush with the sleeve portions of the rings 59. In a further modification, Fig. 7, the heater element 69 is placed outside the enlarged end 62 of the cathode rod.

Title: Improvements in or relating to apparatus for amplifying small movements
IPC: H01H45/00
Filed: 1925-02-05
Abstract: 256,285. Creed & Co., Ltd., Creed, F. G., and Orling, A. Feb. 5, 1925. Receivers with fiuid-pressure source of power, siphon recorders.-Relates to apparatus for amplifying small movements, such as those in telegraphic receivers, in which the initial small movement is imparted to a vane or like baffle controlling the outlet of fluid from a chamber to which fluid under pressure is constantly supplied, and in which a member responsive to the changes of pressure in the chamber acts through further motion-amplifying connections to produce the desired amplified movement. The baffle is arranged to bd at all times out of contact with the fluid outlet nozz'e, and the pressure-responsive device is a spring-controlled piston mounted out of sliding contact with the walls of the chamber. Fig. 2 shows the application to the actuation of a siphon recorder 5 from the moving coil m of a telegraph receiving apparatus. Three cylinders a of successively increased diameters, each supplied through a passage h, Fig. 5. with air under pressure from a common chamber b, are employed in series. The coil m carries a vane k movable towards and from the outlet nozzle j of the first cylinder a without contact therewith, being held in its normal position against the pressure of the issuing air by a. spring, or, by the torsional suspension of the coil, or by the pressure of a second jet of air. The pressure acts on a piston g, Fig. 5, of slightly smaller diameter than the cylinder, the piston rod r being carried by spring blades 9, 9<a> to support the piston out of sliding contact with the cylinder. The rod r carries a baffle s which similarly controls the outlet from the second cylinder, and the pressure in this cylinder controls in turn a baffle s controlling the outlet from the third cylinder. The rod r associated with the third cylinder carries a member t bearing against the end of a thrust rod u acting on a lever v under control of a spring y. The lever v actuates the siphon of the recorder through a thread 1 and a lever 2 under control of a spring 2a, or, instead of actuating a recorder, may carry relay contacts. Alternatively the various baffles may move transversely to the nozzles j. Fig. 7 shows an alternative connection between the last piston rod r and the recorder. A thread 10 is secured at one end to the rod, at the other end to a fixed member 11. and at an intermediate point to one end of a thread 12 of which the other end is secured to a fixed member 13. An intermediate point 12a of the thread 12 is connected bv a thread 14 to a spring-controlled lever 15 for actuating the recorder.

Abstract: 1,134,325. Pulse-duration discriminating circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 27 Jan., 1966 [4 Feb., 1965], No. 3721/66. Heading H3T. A pulse-duration discriminating circuit comprises an integrating circuit which renders an electronic switch conductive when an input pulse exceeds a predetermined duration and thus short-circuits the output terminal to which the differentiated input pulse is applied; the electronic switch becomes non-conductive again after a delay. The input pulses are applied at E to a Schmitt trigger which provides outputs at A 1  and A 2  of constant amplitude and rectangular shape. The A 1  output is a differentiated output and is taken off at A 4  through capacitor C 2 . The other output A 2  is passed through an integrator R 1 , R 2 , C 1  and if long enough produces a voltage to break down a Zener diode D 1  and make transistor T 8  conduct, thus shorting A 4  to O through diode D 3 . Diode D 2  shorts R 2  for the discharge of C 1  so that the circuit restores to receive another pulse in a time depending on C 1  and R 1  only. If the input pulse ends while T8 is still conducting, its differentiated trailing edge will be shorted by the transistor and the voltage at A 4  will not change. The potentials at A 3  and A 4  may be applied to the two inputs of a multivibrator (not shown).
