Title: Improvements in funnels for liquids
IPC: B67C11/06
Filed: 1924-02-16
Abstract: 233,797. Hall, A. J., Barnes, J. O., and Ness, P. Feb. 16, 1924. Funnels.-Relates to funnels in which the supply of liquid to the bottle &c. is automatically stopped when the bottle is filled to the desired height and in which the funnel is automatically closed when it is removed from the bottle &c. The funnel is of the type in which the filling-tube 3 connected to the cup 1 of the funnel carries a pin 11 adapted to slide in a slot 10 in an outer tube 4 having a flange 5 to rest on the top of the bottle during filling, a float 8, cone-shaped at its upper end and open below, engaging when the bottle is filled to the desired height with a seating on the tube 3 to stop the flow of liquid. An exchangeable sleeve 6 inserted loosely in the upper end of the tube 3 forms the seating for the float 8 and determines the quantity of liquid to be run into the bottle. The tube 3 is screwed into the cup 1, and the sleeve 6 is supported by an angular flange 7 resting on the top of the tube 3. During filling, a ball valve 13 rests on a support 14 on the outer tube 4, and when the funnel is removed from the bottle the ball engages a seating 12 on the lower end of the tube 3 and prevents the escape of liquid. Rows of corrugations 15 formed by inwardly indenting the tube 3 form guides for the float 8, which normally rests on a transverse pin 9 in the tube 3. Radial grooves 16 or the like in the flange 5 allow air to escape from the bottle during filling.

Title: Method and means for standardising of high frequencies
IPC: G01R23/00
Filed: 1944-03-08
Abstract: 575,223. Frequency measurements. FINDEN, H. J., and PLESSEY CO., Ltd. March 8, 1944, No. 4306. [Class 37] A frequency measuring system comprises two high frequency oscillators, one adapted to be synchronised with the frequency to be determined, the other being set to a near frequency in terms of a harmonic series of a frequency standard, a modulator which is fed with the outposts from the two oscillators, and a calibrated resonant circuit for measuring the frequency difference. A cathodetapped oscillating detector A<3> using a high-frequency pentode with supressor grid provides oscillations rich in harmonics covering the range from say 10 to 20 Mc/s and is set so that n times its frequency beats with the frequency of the wave K to be measured. A second cathodetapped oscillator C<3> using a highfrequency pentode is set by reference to a harmonic frequency standard B<3> which consists of a 100 Kc/s crystal maintained by a pentode from which a second pentode is driven to produce harmonics of the crystal frequency. The oscillator C<3> is set to the nearest but one of these harmonics lower than the frequency of the oscillator A<3>. The outputs of the oscillators A<3>, C<3> are mixed in a modulator D<3> consisting of a triode-hexode valve and fed to a calibrated resonant circuit E<3>, which is continuously variable between 100 and 200 Kc/s. This is adjusted until maximum response is given by a resonance detector F<3>, when the frequency to be measured is n times the sum of the frequencies of the oscillator C<3> and the resonant circuit E<3>. The oscillator C<3> may have its scale calibrated to indicate 100 Kc/s. above its true frequency and the resonant circuit may be calibrated to read 100 Kc/s. below its true frequency, a direct reading then being produced. A ganged 3-way switch L and a low frequency amplifier G<3> are provided for adjusting the oscillators A<3>, C<3>. A frequency divider consisting of a 10Kc. multivibrator locked by the 100 Kc. standard frequency may be provided for checking the calibrated resonant circuit E<3>, the output from the frequency divider being injected by a switch N. The frequency range may be extended by means of an additional highfrequency oscillator having an output rich in harmonics. An harmonic of the oscillator A<3> may be utilized to monitor or to lock the frequency of the additional oscillator.

Title: A thread pack adapted for treatment by means of liquid or gaseous agents
IPC: D06B23/00
Filed: 1958-02-11
Abstract: 872,649. Packaging. BUDDECKE, H. Feb. 11, 1958 [Feb. 16, 1957], No. 4366/58. Class 94(1). [Also in Group IX] A pack of textile material in the spun or unspun state for treatment with liquid or gas, or when of small dimensions holding material for knitting or harvest-binding, comprises a number of layers wound in a number of equal flat coils arranged so that the upper run of one coil overlaps the lower run of the adjacent one as at 2, Fig. 1, alternate layers being arranged without interleaving so that the direction of the windings in one layer is at an angle (preferably of 90 degrees) to that of the windings in the adjacent layer. The layers may be of rectangular shape, and the pack may be similarly of rectangular section, or due to the relative angles of the layers cylindrical. For treatment e.g. with liquids with the aid of supersonic vibrations the pack may be inserted in a casing the walls of which may be plain or undulated and perforated or formed of bars, plait or mesh, or constituted by strips. The pack may be lightly compressed by superposed rings with or without springs or a similar lower ring, and a closure may be provided with which the material can be withdrawn. The pack may be made by passing yarn, &c. through a guide 22, Fig. 8, with an offset outlet 24 rotatable to wind a number of turns on a mandrel 26 rotatable when each layer is so formed, the rotation is interrupted and the layer is then moved by constantly-rotated bands 28 on to a conveyer band 29 where the coils are flattened by a similar band 44 while being conveyed to a receptacle 32. Meanwhile rotation of the guide is restarted to form a further layer. As each layer is ready for deposition, the receptable is rotated through the desired angle, in this case 90 degrees, through a one-way drive from a pinion 56, which cooperates with a rack 58 as the carriage on which the receptacle is mounted is moved by a rod 55 the end of which moves in a rotating cam slot 53. With each forward movement of the receptacle a screwed rod 63 is rotated through a ratchet and pawl 64, 66 to lower a plate 62 on which the layers are supported, the driving current being cut off completely when a switch 67 is operated by the descent of the rod 65. Specification 738,821 is referred to.

Abstract: 176,625. Atkinson, J. S., and Stein & Atkinson, Ltd. Feb. 8, 1921. Charges, conveying through furnaces. - In a continuous furnace for heating billets or like objects of irregular shape, the articles are prevented from piling one upon another by being carried through the furnace on slippers resting on stationary longitudinal skids. As shown, the furnace chamber 2 is provided with longitudinal water-cooled skids 1 of circular cross-section, on which rest slippers 5 formed of lengths of metal shaped on one side to fit over and partly encircle the skid, and on the other side to provide a flat surface to receive the billets 6. Some of the slippers may be provided with a boss 5a at one end to contact with billets which are placed directly on the skids. The slippers are moved along the skids by a pusher, the head 8 of which is pivotally mounted on the end of the movable member 9 and counterweighted so that normally it acts on the ends of the slippers. When the head 8 is moved about its pivot by a hand-lever operating through a rod 11 and arm 12 it acts only on the billets.
