Abstract: 250,386. Tate, G. E., Monkhouse, F. O., and Walters, A. F. March 26, 1925. Clockwork actuation. -An electric switch, such as is used for automatically lighting and extinguishing street lamps, comprises a graduated disc m rotated once a day by a clock, and having adjustably secured to it by a nut p two arms n, o. The in " arm o has a projecting pin r, which at a predetermined time engages a lever i, pivoted at io, and rocks it so that a nose i<1> thereon is withdrawn from under a platform j', thereby allowing a lever a pivoted at b to fall, bringing contacts d, e into engagement and completing the lamp circuit. The lever i afterwards returns to its initial position but with its nose i<1> above the platform j<3>. This platform is integral with a lever j pivoted to the lever a at j<1> and limited in its upward movement relatively thereto by a lug jo projecting under the lever j. By the time the lamp is to be extinguished the " out " arm n has turned to such a position that a cam q thereon has engaged a second lever f and turned it about its pivot g so as to strain a spring h. The lower end of the spring is secured to the lever j. As this lever is now fulcrumed at the point where the platform j<3> contacts with the underside of the nose i', the pressure between the contacts d, e is enhanced. A short while later, a pin q<1> on the arm n contacts with the lever i, which is thereby rocked so that the nose i' is withdrawn from above the platform j<3>, allowing the spring h to raise the arm a and make a quick break between the contacts d, e. The lever i and afterwards the lever return to their initial positions, so that the apparatus is reset ready for a repetition of the cycle of operations. Contacts.-The contact d is secured to the lever a by a flexible connection d' so as to make thorough surface contact with the fixed contact e.

Abstract: 385,570. Coating webs. DU PONT DE NEMOURS & CO., E. I., Wilmington, Delaware, U.S.A. March 20, 1931, No. 8590. Convention date, March 20, 1930. Void [Published under Sect. 91 of the Acts.] [Class 140.] Apparatus for applying stripes of colouring material to a moving sheet or web of paper or fabric comprises an elongated trough formed of two separable plates 1, 2, Fig. 2, passages or slots being formed along the lower edge of the wall 1, or preferably in a detachable plate 4. The plate 2 is bevelled at its lower edge to lie flush along the plate 4, and contact closely therewith. The plates are connected together by means of an arm 11 on the plate 1 pivoted to an arm 9 on the plate 2, and a turnbuckle 12 pivoted to an arm 13 on the plate 1 and engaging in a hole 16 in the plate 2. Tilting and supporting means for the trough comprise a heavy bar 20, Fig. 1, to each end of which is secured a bracket 21 by means of a tongue 22 recessed into the bar. The trough is bolted to the bar 20. The brackets 21 are adjustably secured to brackets 23 fixed to the framework of the apparatus, the two brackets being pivoted at one point, but made capable of relative adjustment through a limited angle, The sheet material to be striped unwinds from a roll 30, passes over a roll 31 and under the trough, which is lowered until it produces a slight depression in the run of the material. The material then passes through a heated drying chamber 50, and is received on a roll 32. The effective width of the trough is varied by means of removable rubber bulkheads 2<1>, which confine the colouring matter to the part of the trough desired. A form of trough divided into three compartments 33, 34, 35, Fig. 6, may be used, each compartment having a separate opening, and being supplied with a different colour. The compartments are preferably separate so that they may be spaced as desired. As shown in Fig. 7, each chamber 35 is constricted at the bottom to form a flat portion that may be clamped between the plates 1, 2, and is provided with a hole 36 which communicates with one of the slots 5 in the plate 4. Specification 384,293 is referred to.

Title: Frequency marker pulse circuit
IPC: G01R27/32
Filed: 1957-03-15
Abstract: 817,195. Frequency measurement. STANDARD TELEPHONES & CABLES Ltd. March 15, 1957 [March 15, 1956], No. 8595/57. Class 37. [Also in Group XL (c)] In a circuit for producing a marker pulse for a cathode-ray oscillograph in testing the frequency characteristics of electrical transmission equipment, the pulse is produced as the output 20, Fig. 2, of an ascending swept frequency generator passes through a specified frequency; the swept frequency is fed to terminals 30, 31 of a differentiating circuit, Fig. 3, comprising a capacitor 32 and resistors 33, 34; and the resulting output varying with frequency 21, Fig. 2, after passing through a cathode follower circuit 37, Fig. 3, is rectified at 40 and accumulates in capacitor 41, as represented by 22, Fig. 2. Terminals 30, 31 also feed the swept frequency to an attenuator 43, 44, 45 and the signal developed across resistors 44, 45 is rectified at 51 and charges capacitor 52 to a reference level of about half the maximum potential of capacitor 41; 23, Fig. 2. The potentials across capacitors 41, 52 are fed to differential amplifier 56, and the inverse potentials, curves 22, 24, Fig. 2, developed at the plates 66, 67 are amplified at 68 and passed to the anodes 70, 71 of rectifier 69. At any instant, the anode at the higher potential will conduct, and the anode at lower potential will be blocked since its cathode is substantially at the same potential as the other anode; the resulting voltage at the junction of resistors 74, 75, as represented by curve 26, Fig. 2, peaking to form a marker pulse at the value of frequency corresponding. to the intersection 25 of curves 22, 24 with reference level 23; this marker pulse being sharpened to the form 27, Fig. 2, by reducing resistor 61 to zero. Variable resistor 82 controls the pulse amplitude, and positive excursions of the rectifier 69 output are shorted by diode 77. The signal 27 is passed through amplifier 84 to output terminal 85. The capacitor 52 slowly discharges through resistor 55, fluctuations in the input signal level are therefore followed by the potential across this capacitor. The capacitor 41 is discharged at the end of each frequency sweep by supplying a positive pulse to the grid of gas triode 53 from the trigger circuit of the sweep oscillator. The frequency at which the marker pulse is derived is determined by varying resistor 34 and thus the characteristics of the differentiating circuit; a calibrated frequency dial may be attached to this resistor. To calibrate this dial, the swept frequency is replaced by a fixed frequency and the dial set to this frequency; the resistor 45 is then adjusted to extinguish the glow-tube 86 across anodes 70, 71 of rectifier 69. An unknown constant input frequency may be similarly determined. A rotary switch 35 enables alternative values of capacitors 32, 41 and of resistor 45 to be used and thus vary the frequency range of the device. In another embodiment, the differentiating circuit is replaced by an integrating circuit, Fig. 4 (not shown), employed with a descending frequency sweep.

Filed: 1923-03-28
Abstract: 216,621. Royce, T. H. March 28, 1923. Controlling variable-speed gearing.-In changespeed gearing, two gears axially-movable on different shafts are operated alternatively according as a main sliding member such as b, Fig. 1, is moved from neutral in one direction or the other. In the arrangement shown in Fig. 1, the slider b turns a disc c which has two crank pins c<4>, c<5> spaced apart. These pins are connected through levers e to striking bars d. As one crank-pin is passing its dead centre, very little movement is transmitted to its striker, while the other is in full motion. The neutral position is shown, and the striker bars are moved alternately in the same direction when the main slider is moved in one direction or the other. In a modified arrangement shown in Figs. 4, 5, and 9, the main slider h carries two pins h<3>, which project from a central web h<2> between diverging jaws i<1>, i<2> and j<1>, j<2> upon two levers i, j pivoted on a fixed shaft g<5>. The lever i engages its striker k directly. The lever j is connected to its striker m by a medially pivoted lever l which reverses so that the gears are moved in the same direction. In the neutral position shown in Fig. 4, the web h<2> engages lateral projections i<11>, j<11> on the jaw members and locks both levers i, j. When the slider h is moved to the right to the position shown in Fig. 9, the lever i remains locked, while the lever j is swung to the parallel position shown. When the slider h is moved to the left of neutral, the levers come to the opposite parallel position shown in interrupted lines in Fig. 4.

Title: Manufacture of sliding clasp fasteners
IPC: B29D5/04
Filed: 1976-03-05
Abstract: 1514374 Making sliding clasp fasteners TURO STENHALL OY 5 March 1976 [5 March 1975] 9024/76 Heading B5A A row of closure members for a sliding clasp fastener is made by feeding a plastics filament F to the toothed periphery 15, 15a of a setting gear 14. A striker 20 is reciprocable axially of the gear and presses the filament into a V- shaped configuration 10c, 10d against a recess 27 in a stop plate 16, this operation forming a locking tappet 12 at the apex of the V. The striker is withdrawn and the V is pushed by a radially movable pusher 21a (or 21b) into a gap between the teeth of the setting gear. The gear is then indexed forward one increment to cause a length of filament 10e to be drawn over the tooth whereupon operation of the striker and pusher is repeated to form another section of the row interconnected to the first. The striket is carried by an arm 22 fixed to a driving shaft 24. The shaft also carries a second arm 23 the free end of which is received in a recess 29 of a body 28 carried by the pusher 21. Thus the movement of the striker and the pusher is synchronised. In the preferred embodiment two rows are simultaneously made by a pair of gears strikers and pushers between which a single stop is located.
