Title: Improved process of and apparatus for severing a part from a hollow glass body by fusion
IPC: C03B33/085
Filed: 1925-10-01
Abstract: 241,189. Naamlooze Vennootschap Internationaal Octrooibureau. Oct. 10, 1924, [Convention date]. Shaping glassware after formation.-Relates to a method of separating hollow glass articles, particularly electric lamp bulbs, from the surplus neck portions to which they are attached after removal from the blowing-mould. According to the invention, separation is effected by means of a gas flame, applied to the interior of the neck of a bulb, which melts through the glass and prevents the rim of the finished bulb from flanging inwards. The bulb 49 is shown held by a ring mould 11 a number of which are mounted on a table 81 forming part of an automatic bulbblowing machine, means being provided for rotating the mould at appropriate times. The upper edge of the neck of the bulb is held 'between spring-operated grippers 33 and the lower edge of a cylindrical member 11<a>. A burner 5, having a ring of jets 10 and to which gas and compressed air or oxygen is supplied through tubes 6, 7, is movable vertically through a guide sleeve 3. In order to sever the bulb from the surplus neck portion or " lost head," the burner is lowered through the ring mould, which is in rotation, and flames from the jets 10 fuse through the glass along a narrow circumferential zone. The pressure of the flames also prevents the fused rim, which forms the edge of the finished bulb, from flanging inwards. During this operation, the bulb is supported, and centred. The supporting-device consists of a seat 55 looselv mounted on a shaft 53 which is movable vertically and is rotated in unison with the ring mould. A frame 66, pivoted on the upper end of the shaft 53, carries rollers which centre the bulb. When the neck of the bulb is fused, the frame is lowered and the bulb detaches itself from the " lost head." At the same time, a bifurcated lever 73, operated by the movement of the frame, is turned about its pivot 74 and removes the bulb from the machine.

Abstract: 805,963. Automatic gramophones. HANSEN, H. C. Aug. 26, 1955 [Aug. 27, 1954; Sept. 17, 1954], No. 24596/55. Class 40 (2). In a record changer of the kind described in Specification 801,174, the cam disc 26 is adapted to cause the pick-up arm to be pressed upwardly against the lowest record of the stack, and moved in a generally outward direction interrupted by inward movements in the edge orbits of records of different sizes so that engagement of the abutment 70 on the pick-up arm with the edge of the record unseats the record and determines the setting-down position of the pick-up arm. During playing of a record a spring- loaded cam-follower 66, Figs. 2 and 20, is free to traverse a recess a, Fig. 8, in the cam-disc 26. At the end of the record the follower 66 may rest at a<SP>1</SP>, and the initial rotation of the camdisc 26 causes the follower to ride up over a slightly raised area a<SP>2</SP> and swing outwardly a small amount to take the abutment 70 outside the periphery of a smallest size record. The follower 66 then enters track d<SP>1</SP> and if the abutment 70 encounters the edge of a record, the follower 66 is forced to ride up a ramp d<SP>2</SP> so that the large diameter end of follower 66 engages the edge d<SP>3</SP> of a plate 73a. The space between plates 73a and 73b for the follower 66 to pass therebetween is therefore carried on over a raised portion e<SP>1</SP> in the cam-track e corresponding to the smallest sized record. If the lowest record of the stack is not the smallest size, the follower 66 does not ride up ramp d<SP>2</SP> but remains on the bottom of the track and passes between plates 73a and 73b owing to the recess 56 in the follower 66. The pick-up arm thus continues its outward movement along track f until reaching a further inwardly-directed part h<SP>1</SP> which produces a similar operation with regard to a medium sized record in the presence of which the follower 66 passes over to track f. In the absence of a medium size record, the follower passes between the edges h<SP>6</SP> and h<SP>7</SP> of plates 73a, and 73b, respectively, to a track g corresponding to that for the largest size record. Modifications of the cam-disc 26 shown in Fig. 8, are described with regard to Figs. 21 and 22 (not shown). Specifications 757,303, 770,544 and 805,964 also are referred to.

Abstract: 406,748. Actuating- materials; valves. ERREN, R. A., 299, Seven Sisters Road, London. Sept. 8, 1932, No. 25075. [Classes 7 (ii) and 7 (vi).] Hydrogen is used either with air or oxygen as the comburant and with or without hydrocarbon ; the mixture is maintained in a turbulent state until ignition and the amount of comburant is regulated in accordance with the fuel supply. The hydrogen may be added to a charge within the cylinder. When oxygen is used as the comburant, water or a part of the exhaust is used in each succeeding cycle to absorb the effect of the combustion ; this may be collected in a chamber heated by that part of the exhaust not to be further used or it may be supplied by a pump S, Fig. 3, which abstracts a part from the baffled chamber p and delivers it to the pipe f, leading to the engine cylinder. An adjustably spring loaded valve e allows part of the exhaust to pass to atmosphere. Valves.-When hydrogen is used with other fuel mixtures, the two parts forming the charge may be admitted to the cylinder through coaxial beat valves ; or the mixture may pass along a passage 10, Fig. 7, when the cylinder valve 12 opens and draw along hydrogen from the pipe 11 through the double beat valve 14, 15. The upper closure plate 14 is mounted between springs on the valve spindle 13 and stops the flow of hydrogen before the main valve 12 is closed, thereby ensuring that the passage 16 is free of hydrogen during the ignition period.

Filed: 1959-07-24
Abstract: <PICT:0905287/III/1> An apparatus for producing a stack 33 of unexpanded honeycomb material comprises a support 1 for the stack 33, a head 7 mounted for repeated forward and return motion over the support 1, a device 9, 11 on the head 7 arranged to deposit a set of parallel bands of adhesive on the stack 33 during the return motion of the head 7 and a set parallel to and staggered relative to the first set during the forward motion, and a conveyer 19, 21 mounted for reciprocation over the support 1 in synchronism with the head 7 for engaging sheet material 27, carrying it over the adhesive bands, and there releasing it.  The head 7 reciprocates horizontally between positions 7, 71 and carries a pivoted member 13 in which rollers 9, 11 are mounted, the rollers being fed with adhesive by transfer rollers 17.  The apparatus operates as follows:-a sucker 23 on a pivoted arm picks up a sheet 27 from a stack 29 and an arm 31 moves from 311 to provide a guide, a sucker 21 on the head 7 engaging the sheet 27.  The sucker 23 is cut off, and the head 7 carries the sheet over the stack 33, the roller 9 adding the second set of bands to the top sheet on the stack.  At the position 71 the sucker 21 releases the sheet 27 and a sucker 19 engages a fresh sheet from a stack 35. During the return motion, the roller 11 deposits the first set of bands on the sheet 27, the member 13 having been pivoted.  The support 1 and supports 3, 5 for the stacks 29, 35 are adjusted vertically during operation.  All operations are carried out automatically. In a modification, the supports 3, 5 are replaced by supply rolls, cutters being provided adjacent bars 31, 37.  In another modification, the conveyer is separate from the adhesive-depositing head and reciprocates in a direction at right angles to the direction of movement of the head.  The conveyer takes sheets from stacks at one or both sides of the table 1 and releases them in the path of the head 7 which thus prints a number of stacks 33 simultaneously.  In another embodiment, Fig. 2 (not shown), the top sheet on each stack 29, 35 is moved by a sucker over a ramp towards the support 1 before being engaged by the suckers 19, 21 which are movable vertically, the head 7 being reciprocated by an endless chain, and in a modification of this embodiment, a pair of rails are substituted for each ramp.  The rollers 9, 11 are driven in opposite directions by an electric motor.  Specification 591,772 is referred to.
