Abstract: 1,144,652. Glass feeder apparatus. OWENSILLINOIS Inc. 28 April, 1966 [29 April, 1965], No. 18577/66. Heading C1M. A glass feeder orifice ring assembly comprises at least one refractory orifice ring 29 (Fig. 2) of substantially frusto-conical configuration forming a downwardly converging discharge orifice, an annular wall member 33 extending downwardly around the or each ring 29 outwardly thereof and separated thereform to form at least one combustion chamber 35 circumscribing the or each ring above the discharge orifice, the lower extremity of the or each combustion chamber having a downwardly facing, restricted outlet 37 forming an annular exhaust passage at the lower extremity of the wall 33 around the discharge orifice, and inlet means 42 communicating with the or each chamber 35 for supplying a combustible gas thereto, to combust the gas therein and exhaust same downwardly through the exhaust passage 37. The inlet means 42 is annular and is restricted, and also communicates with a manifold40extending peripherally around the ring 29 and wall member 33. Gas is fed to the manifold 40 through inlet pipe 41. To obtain the best heat exchange possible eight vertical radial baffle plates 43, which also act as spacing members, are formed in the chamber 35 integral with the wall member 33. So that greater control of the heating of the orifice ring and hence greater control of the shape and weight of the gob to be formed the manifold may be in the form of eight separate members 55-55g (Fig. 5) each separately controlled and with one manifold to one of the eight segments of the chamber 35 formed by the baffle plates 43. Additionally the inner surface of the orifice ring can be provided with a metal liner. Whilst the above has related solely to singlegob feeders a further embodiment is described with reference to a double-gob feeder (Fig. 6). In this embodiment there is shown an orifice ring member 76 which defines a pair of frustoconical walls 77, 78 integrally connected by an inverted V-shaped web 79. An annular wall member 85 extends downwardly around the walls 77, 78 of member 76 and has an integral inverted V-shaped portion 86 which fits within, but spaced from the web 79. Within the wall member 85 are two sets of four arcuate grooves 88-91 and 88a-91a, one set encircling each of the walls 77 or 78 and each grooveformingacombustion chamber. Each groove connects downwardly with a downwardly formed passageway 95 of smaller cross-section but radially co-extensive therewith. The member 85 is also formed with twelve transverse tunnels 96-101 and 96a- 101a, six to each set of arcuate grooves 88-91, 88a, 91a. The outer end of each tunnel is connected to a manifold N and a burner N<SP>1</SP>. The inner ends of the tunnels flare outwardly gradually to communicate with one of the arcuate grooves. Thus as each burner is individually controllable it is possible to carefully control the temperature distribution around each part of each orifice ring.

IPC: C10G21/00
Filed: 1929-06-18
Abstract: 336,945. Kßrpßti, J. June 18, 1929. Pitch and tar. - In the separation of tars, tar oils, petroleums, &c., which may contain viscous hydrocarbons such as naphthenes or ethereal oils such as terpenes, the raw material is dissolved in an aqueous organic medium at an elevated temperature and the solvent capacity of the medium reduced in stages. Increased pressure and a temperature above the boiling-point of the solvent may be used. Substances may be added to promote solution, such as low-boiling coal-tar fractions, alcohols, esters, ketones, phenols, &c. Solvents may be selected to leave the pitch &c. undissolved. Reduction of solvent capacity may be effected by reducing the pressure, temperature or concentration of the solvent, or by addition of salts. The preferred temperature range is 20-150‹ C., higher temperatures being avoided to prevent polymerization; a pressure of 8-10 atmospheres may be used. In an example, 1 volume of tar is dissolved, except for pitch, at 148‹ C. in 6 volumes of a 55 per cent aqueous-alcohol in a stirring- 'vessel 1 and the solution passed through tubes 4 - - 10 and progressively cooled, the temperature drop between any two adjacent tubes being about 17‹ C. Seven fractions are obtained and can be run off through valves 11 - - 17 respectively. The fractions comprise saturated and unsaturated hydrocarbons, phenols, &c. respectively.

Abstract: 721,446. Windscreen cleaners. LAMAUDIERE, P. F. J. Aug. 8, 1951 [Aug. 18, 1950], No. 18720/51. Class 138 (1)  A vehicle windshield wiper; Fig. 1, adapted to be actuated either automatically by a source of power, e.g. by one of the movable parts of the vehicle such as the speedometer through the agency of a worm 5 and a worm wheel 4, or by hand, by means of a manual control member 11, wherein torque limiting means are inserted between the worm wheel 4 and the member 11, is characterized in that the worm wheel 4 is keyed to a hollow spindle 7, which is closed at the end remote from the member 1 and within which spindle is adapted to slide a piston assembly to which the member 11 is secured and in that a spring 18 resting on an inner shoulder 19 in the spindle 7 urges the piston assembly frictionally against the closed end of the spindle whilst the end of the spindle adjacent the member 11 is provided with at least one notch, e.g. 20, Fig. 2, adapted to be releasably engaged by a stud 21 fixed to the piston assembly. The worm wheel 4 is connected by a crank 2 to a connecting rod 1 for actuating the wiper arm (not shown). The hollow spindle 7 is axially slidable in fixed bearings 8, 9 to allow manual operation, and the piston assembly comprises two pistons 14, 17 secured to the ends of a rod 16, the piston 17 being urged against the closed end of the spindle by the spring 18 and the piston 14 having secured thereto the control knob 11. Two diametrically opposed studs on the piston 14 engage with two notches 20 in the end of the spindle 7. If the knob 11 is restrained from rotation as the worm wheel 4 is rotated by the worm 5, the piston 17 is moved out of frictional engagement with the closed end of the spindle against the action of the spring 18 owing to the studs sliding up the sides of the notches 20, so that the knob is disengaged from the worm wheel 4. In a modification, the knob 11 is mounted in the vehicle to prevent axial movement and when restrained from rotation during automatic action of the wiper, the spindle 7 and worm wheel 4 move axially in the direction of the arrow 10 to disengage the wheel from the worm. The wiper can thereafter be operated manually since the studs will be bearing frictionally against the unnotched portion of the open end of the spindle 7.
