Title: Electrically controlled weight-dosage arrangement for apparatuses for decanting liquids
Inventor: CHECUCCI TOMMASO MORI
IPC: G01G13/00
Filed: 1960-04-13
Abstract: 909,197. Weighing apparatus for liquids. O.C.M.E. S.r.L. April 13, 1960, No. 13238/60. Class 143. [Also in Group XXIX] Liquids, including viscous liquids, are dispensed by weight in apparatus comprising a balance and a flow control in the form of a valve closable in two stages to provide bulk and dribble feeds, the bulk feed being terminated by a partial closure of the valve initiated by means engaged by a moving part of the balance and the dribble feed by a full closure of the valve in response to the output of a photo-electric device. In use, a container 12 to be filled rests on one pan 3 of the balance 1 and below the feed valve 10 through which liquid from a supply source (not shown) flows. When counterweights 13 are not quite overbalanced a switch 50 is operated by the balance to de-energize an electromagnet 43 whose armature 42a is thereby released to allow the spring 46 to move the valve 17 into the state shown in which pressure from compressed-air in a pipe 39 is communicated to line 35 to act on the lefthand side of the piston 21 in the cylinder 19. This piston is fixed so that the cylinder itself moves, pushing with it the cylinder 20 and its piston 23 whose stem 24 in moving rotates lever 28 which operates ratchet 30 to move the plunger 31 downwardly so partially closing the valve 10. The orientation of the balance beam is indicated by a pointer 5 (Fig. 2), carrying a mirror 57 which, at balance, is arranged to reflect light from a lamp 55 onto a photo-electric cell 54 which, by an amplifier 53 is made to operate a relay 52 which deenergizes the electromagnet 51 to operate valve 18. The latter then allows supply of compressed-air via line 37 to move the piston in cylinder 20 to complete the closure of the feed valve 10. The extent of opening of the valve 10 during the dribble feed is adjustable by means of the setting of screw 26 whose shank carries the fixed support 25 for the rod 22 of piston 21, and the exact weight at which final cut-off occurs is adjustable by bodily movement effected by screw 16 (Fig. 2), of the housing 15 supporting the photo-cell and its auxiliary equipment. The aperture 33 in the valve plunger 31 is stated to prevent bubble formation at the instant of cut-off

Junction boxes and their covers for use in the conduit system of wiring are so constructed that the same form of box, which is provided with the maximum number of conduit outlets required, may be used (in conjunction with a deep-rimmed lid which may be readily formed with the necessary number of cut-away slots to allow it to pass on to the box and over the conduits) whatever number of conduits leave the box, up to the maximum provided for. In the arrangement shown in Figs 1 and. 4, a cast box is provided with four outlets b terminating on the outside flush with the wall of the box. The conduits are attached to the box by any suitable means, for example those described in Specification 24742/14. In the example, shown in Fig. 1, two conduit tubes are connected, and a lid with two slots e, Fig. 4, to pass over the tubes is employed. The standard lids may be without slots, but formed with stampings for enabling the metal opposite any required opening to be cut away easily. The unused outlets are covered by parts of the lid which are not cut away. In a modification, the base of the box is a skeleton structure with upstanding parts formed with screwed radial slots to take the screwed conduit. In this form, the lid closes the spaces between the upstanding parts.

Abstract: 737,424. Dielectric heating. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 12, 1954 [May 12, 1953], No. 13274/53. Class 39 (3). Multi-layer strip material 1 impregnated with a thermoplastic and to be formed into a single composite belt is passed between an earth roller electrode 2 and a metallic belt electrode 3 extending between rollers 4 and connected through condenser coupling plates 6 with an oscillator 5. The roller 2 is urged towards the belt 3 by spring means 7. The power fed to the electrodes is varied by varying the spacing of the plates 6 from the belt 3 so that the strip temperature is maintained substantially constant. A temperature-responsive device 10 actuates a control device 9 which acts through parts 8 to adjust the positions of the plates. After heating, the strip may pass between pressure rollers 11. Alternatively, the strip is passed around the roller 2 a greater amount by means of an additional guide roller, and is pressed against the roller 2 by further pressure rollers. To prevent the strip sticking to the electrodes bands of low-loss flexible dielectric material 14, 16, Fig. 3, are interposed between the strip and the electrodes.

Abstract: 378,840. Moulding hollow-ware from pulp. ARENDT, O., 179, Kurfurstendamm, Berlin.-(Assignee of Smith, E. Ross- ; Penig, Saxony, Germany.) May 11, 1932, No. 13601. Convention date, May 12, 1931. [Class 87 (ii).] Hollow articles moulded from pulp are removed from the couching moulds by vertically - movable stripping-moulds acting in conjunction with an air-pressure system. The couching mould 10 with the moulded article 11 inside is brought over the stripping mould 7 and the latter is raised by pressure applied to the bar 14 until the mould can be locked to the cylinder 3 by the ring 15. During this movement the plate 6 and mould walls 7 enter some distance into the mould 10. By admitting compressed air through the valve 3a the piston 2 compresses the packing 9 to form an air-tight closure and the piston 1a raises the plate 6 and mould walls 7 into contact with the article. The conical member 7a, fixed on the piston rod, presses against the lower end of the walls 7 and also maintains an airtight closure at 8 during this process. Compressed air at this stage is admitted through the valve 12a and passes through the perforations 12, 13, 16 to the exterior of the article which thus is released from the mould, the action continuing until the pressure begins to force piston 1a downwards again, on which the valve 3c is opened to exhaust, the ring 15 detached and the mould 7 lowered with the object resting thereon. The plate 6 has a certain amount of sliding play in the member 6a.
