Title: Improvements in or relating to means for removing bottles from conveyors
IPC: B08B9/44
Filed: 1946-05-29
Abstract: 621,961. Endless chain conveyers. LUND, J., DAWSON, G., DAWSON, D., and DAWSON, BROS., Ltd. May 29, 1946, No. 16370. [Class 78 (i)] In a bottle-handling apparatus of the kind having a conveyer which carries bottle holding cups, which conveyer turns over sprockets at a discharge station to enable the bottles to slip out of the cups downwards, and having a movable unloading tray to receive bottles from the conveyer as they slip out of the cups and to transfer them to a table, the tray is mounted so as to be raised into a bottle receiving position to collect the bottles directly from the conveyer and thence to be lowered away from the conveyer towards an unloading table and turned as it is lowered, so as to bring the bottles into an upright position and lower them on to the table, and means are provided to cause the bottles to be pushed along the table away from the conveyer. The step by step conveyer has chains 13 and 14, Figs. 1 and 2, which turn over sprockets 11 and 12 so that the bottles are brought into a downwardly inclined position in combination with a movable unloading tray 44 which, when in the unloading position, touches the bottles 22 causing them to fall into recesses on the tray where they are held by brackets 47 forming combs which are free to push through slots 59 in the table 60. The tray 44 is carried by an arm 45 pivoted eccentrically on the disc 51 which is mounted on a rock shaft 52, and has abutments 58 which underlie the arm 45 and prevent the unloading tray falling under its own weight. Rotation of shaft 52 by pinion 56 and rack 57, operated by a fluid pressure mechanism (not shown) turns the tray bodily to a discharging position as shown in Fig. 3 wherein the bottles are carried erect and are deposited on the combs 59, and further rotation of the shaft 52 imparts a horizontal motion to the tray 44 which pushes the bottles onto the table 60 in their erect position. To maintain the bottles endwise on the conveyer when they turn around the sprockets a plurality of curved guards 23, which are yieldingly urged inwards towards the bottles, extend around this portion of the conveyer as far as the point where the bottles contact the tray, said guards being suspended from pivoted links 25 the upper pivot 26 of which forms a cross rod, the ends of which are fitted to arms 27 rotatable with a cross shaft 28 one end of which is extended, as shown in Fig. 4, and has attached thereto a spring 35 and dogs 33, 34 which maintain the shaft 28 in any position to which it is moved by the double arm lever 40 which adjusts the guards to the correct height for operation with bottles of any size or shape. Each step of the conveyer is arranged to correspond with the distance between successive bottles and the movement of the tray to the discharge position and its subsequent return to the receiving position is arranged to take place while the conveyer is at rest. Specification 626,639 is referred to.

Title: Improvements in or relating to the manufacture of steel
IPC: C21C7/00
Filed: 1963-04-26
Abstract: In a method of adding the machinability improving elements tellurium and/or selenium to steel, the said elements are placed in a receptacle prior to the introduction of molten steel therein, and at a location such that the said elements are protected from the atmosphere by the rising mass of steel in the receptacle, but are not subjected to excessive turbulence resulting from the direct impact of a stream of steel thereon. The receptacle may comprise either a ladle, or an ingot mold into which the steel is teemed by uphill teeming from a central vertically extending trumpet.  Using the former, the said elements may be placed on base of the ladle adjacent to one side, and diametrically opposite to the point at which steel strikes the ladle.  If sulphur is added to the steel in the ladle in a similar manner, it is positioned directly under the stream of steel, or as far from the tellurium and/or selenium as possible. Exothermic ferro-alloys are not added during this process.

Title: Improvements in or relating to moving object detection systems
Inventor: BELTON DENNIS ALBERT
IPC: G10K11/28
Filed: 1962-04-30
Abstract: 1,004,614. Detecting objects by ultrasonic vibrations. DECCA Ltd. July 25, 1963 [April 30, 1962], No. 16485/62. Heading H4D. In a moving object detection system an ultrasonic radiation transmitter 11 and an ultrasonic receiver 12 are located close together and any variations of phase or frequency between the received and radiated signals due to moving objects are indicated by a phase or frequency sensitive detecting system 14. The transmitter comprises a transistor oscillator 10 producing a continuous wave signal, 60 kc/s., which is fed to a piezo-electric transducer 11 for radiating ultrasonic signals. Echoes of these signals are picked up by a second piezoelectric transducer 12 and fed to an amplifier 13 and thence to a phase-sensitive detector 14, described and claimed in Specification 1,004,615 from which an output signal, dependent on the phase relation between the received signals and a reference signal from oscillator 10, is fed to a filter network which passes the low-frequency variations in this output signal produced by moving targets. These low-frequency variations are then amplified in low-frequency amplifier 22. Alternatively a frequency sensitive detecting system may be used which detects the frequency difference between the signals received from moving targets and those from static targets which have the same frequency as the radiated signals. The signal is passed via coaxial cable 23 through a filter 24 which removes any components at the ultrasonic radiation frequency and thence to a rectifying circuit 25 which gives a direct current output pulse only when the output from the phase-sensitive detector 14 is changing. The output from the rectifying circuit is applied to a visual or aural indicator 26 and alarm 27. The transmitting and receiving transducers 30, 31 (Fig. 2) are cylindrical piezo-electric elements arranged one above the other with their axes vertical and aligned and a fan-shaped open-fronted box aerial 35 is provided to give fan-shaped beams having a narrow vertical width, a baffle 37 being provided to prevent direct coupling from the transmitting to the receiving transducer. Protective grilles 34 and 36 are provided. The lower edges of the beams are arranged to be just above ground level so that reflection from the ground is minimized. A logic unit 28, e.g. a rotating magnetic drum storage device, may be provided arranged to pass only output signals indicating for a period of time the presence of a moving target. A pulse modulated or frequency modulated system may be used.

Abstract: 384,582. Fire curtains. MERRYWEATHER & SONS, Ltd., OSBORNE, J. H., Greenwich Road, London, and BURFORD, A. W., Cresta, Kingsway, Petts. Wood, Kent. June 17, 1932, No. 17149. [Class 47 (ii).] The winding-gear of a fire curtain comprises a drum A adapted to be driven by a chain pinion B. The shaft C of the latter is keyed to the expanding member D of a clutch, of which the external member E is formed with a sleeve to which a worm wheel F is keyed. This is driven from an electric motor bv a worm of slow pitch, the angle of the worm thread being such that, when the motor is stationary, the worm wheel cannot be rotated, for example, by the weight of the curtain. The sliding collar G which controls the clutch is actuated by a pivoted fork G<1> which is connected to a member J carrying two pins K. A weighted arm L formed with a handle M passes between the pins K. To raise the curtain, the clutch is engaged by pulling on a cord N, which is then made fast. The motor is then switched on, and the worm drive raises the curtain. For releasing the curtain, the cord N is suddenly released. The arm L strikes the lower pin K, disengaging the clutch. The pinion shaft C can then rotate freely, allowing the curtain to descend without turning the worm wheel.
