IPC: G09F19/10
Filed: 1948-02-27
Abstract: 639,440. Producing bubbles. LEVER BROS. & UNILEVER, Ltd., and ELWES, E. V. Feb. 27, 1948, No. 6146. [Class 132 (iii)] A continuous method of producing a plurality of separate bubbles for display purposes comprises the successive steps of immersing a perforated sheet or mesh in a liquid capable of forming a lather, withdrawing the mesh with a film of liquid thereon and directing an air stream on to the film so as to form a stream of bubbles. As shown, a tube 4, with perforations 6, which is supported by triangular projections 3 at either end of a rectangular trough 2 containing soap solution 1, has one end closed by a plug 5 and the other end connected by the arm 14 to a rotary air blower. A wire gauze cylinder 7, closed at each end by wooden blocks 8 and 9, is mounted so as to rotate freely on the horizontal tube 4, with its bottom part immersed in the soap solution preferably to a depth of 0.5 in. The cylinder 7 is rotated by means of a motor 12 which is linked with a sprocket wheel 10 attached to the block 8 by an endless driving band 11. A perforated tube 16, arranged parallel to the cylinder, is connected to the air blower through an adjustable air valve 21 and the arm 15. The apparatus may be enclosed in a suitable display cabinet. During operation the cylinder 7 is rotated, preferably at between 15 and 20 revolutions per minute, and a film is formed on the mesh as it emerges from the solution which is blown into bubbles by the air jets 6. The subsequent migration of these bubbles is controlled by the air emerging from the perforations 20 in the pipe 16. The bubbles may be illuminated by coloured lighting or a fluorescent substance may be incorporated in the soap solution and the bubbles illuminated by ultra violet light.

Title: Protection relay
IPC: H01H53/10
Filed: 1939-02-24
Abstract: 579,800. Induction relays; regulating-switches. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Feb. 24, 1939, No. 6207. Convention date, Feb. 25, 1938. [Class 38 (v)] An induction relay has incorporated in it means whereby the contacts are operated instantaneously with currents exceeding an upper limit, and operates normally with a time-delay when the current exceeds a lower limit. In the latter case, a worm 4 on the shaft 1 of the disc 18 is moved into engagement with a toothed sector 5 by the magnet 15 attracting an armature 14 on the end of a stirrup 9, which is pivoted at the axis 10 and carries the upper bearing 8 of the shaft 1, the latter thus swinging bodily about the lower pivot 2 against spring-action 12. The initial position of sector 5 about its pivot 6, and hence the time-interval, is determined by an adjustable stop 38 supporting the sector-arm 7. At the expiry of the time-limit, arm 7 engages a rod 42 and rotates an armature 29 about its pivot 50, so causing an arm 30 on the armature to close contacts 31, 32. The armature 29 is pivoted in the air-gap between the main magnet 15 and a rearward extension 28 so as to be acted upon differentially by the magnetic force. An index 34 integral with the armture carries a magnetic shunt 33 whereby the magnetic force, and hence current in winding 17, required to produce anti-clockwise rotation, Fig. 4, of the armature, and hence instantaneous operation of the contacts 31, 32, can be adjusted. Taps from the winding 17 are brought out to rod-like contacts 20<1>-26<1>, Fig. 8, and selectively engaged by a cam 50 operated by the button 27 and indicated on a spring-pressed scale 51. An additional coil affecting the movement of the armature 14 may be energized under control of a directional relay'so as to prevent movement of the armature unless the current-direction is appropriate, Figs. 6, 7 (not shown). The centre of gravity of the movable system 1, 18 is at or below the pivot 2

Title: An improved method of and apparatus for the manufacture of thin-walled glass hollow-ware
IPC: C03B9/24
Filed: 1941-05-19
Abstract: 547,612. Glass manufacture. McNISH, A. F., and MONCRIEFF, Ltd., J. May 19, 1941, No. 6399. [Class 56] A method of making a thin-walled hollow glass arti cle, such as a tumbler or electric lamp bulb, consists in gathering a charge of glass by suction into a mould, and holding the chilled skin of the charge in the. mould by suction while the fluid core of the charge is blown to shape in a finishing mould. The gathering head comprises a hollow spindle 7 rotatable in an outer sleeve 9 to which pipes 10, 11 are fitted. One or more of the heads may be carried by a suitable forming- machine of any known type. The lower end of the spindle carries a gathering mould consisting of an inner part 16 and a cap 17, an axial cavity 18 being formed in the part 16. A plunger 19 slides in this cavity and is actuated by a rod 20. A passage 21 connects the lower part of the cavity 18 with the pipe 10, and another passage 14 connects the pipe 11 with the joint between the mould parts 16, 17. The lower surface of the plunger 19 forms part of the mould cavity and is shaped according to the desired distribution of the glass in the finished article. In use, the head is dipped into molten glass in a trough 27, and a charge of glass is gathered by suction applied to the mould cavity through the joints of the mould parts, the plunger 19 being in its lowest position and the pipes 10, 11 connected to a source of suction. During the gathering operation, the spindle 7 is rotated to assist in circulating the glass in the trough 27, and rotation is continued when the head is raised out of the molten glass and a blade is passed across the bottom of the head to sever the trailing string of glass. A circumferential cut is made in severing and prevents the formation of a shear scar at one side of the charge of glass. After severance, the blade is kept in place, the pipe 10 is connected to a supply of compressed air, the plunger 19 is raised to uncover the passage 21, and the pressure air enters the space 18 and compacts the glass on to the shear blade. After the blade has been removed, the charge is allowed to elongate, and finally the elongating charge is enclosed in a finishing mould and blown to shape. Suction is maintained, during the blowing operation, through the pipe 11, and the passage 14 to hold the chilled skin of the charge of glass in the mould 16, 17. Detachment of the finished article from the mould 16, 17 may be assisted by compressed air applied through the pipe 11. Specification 547,611 is referred to.
