Title: Improvements in or relating to machines for manufacturing hollow glass bodies
IPC: C03B33/085
Filed: 1925-09-29
Abstract: 241,182. Naamlooze Vennootschap Internationaal Octrooibureau. Oct. 9, 1924, [Convention date]. Removing formed articles. - An automatic machine for blowing glassware, particularly electric lamp bulbs, is provided with means for burning-off the finished article from the neck of glass that is held by the ring mould, and for ejecting this neck, or " lost head " from the machine at the conclusion of the cycle of forming-operations. The machine comprises a central rotary column 36 to which a table 24 is secured, and four ring moulds 30 rotatably mounted on the table. Each ring mould is carried by the movement of the table to one of four stations. At the first station, a charge of metal is pressed and blown out to form a parison; at the second station the parison is blown in a finishing mould. After being blown, the finished bulb 55 is separated from the " lost head " 54 which is gripped bv the ring mould. For this purpose, a burner 137 descends through the ring mould and directs sharp flames against the inner wall of the bulb. The flames melt through the glass, while the bulb is being rotated, and the pressure of the flames prevents the upper edge of the finished bulb from flanging inwards. During this operation, the bulb is supported by a seat 63 loosely mounted on a shaft 62 which is movable vertically and is rotated in unison with the ring mould. A frame 64, pivoted on the upper end of the shaft 62, centres the bulb. When the glass is sufficiently fused, the frame is lowered and the bulb detaches itself from the " lost head." After the next movement of the table, the ring mould stops below a plunger which descends and pushes the " lost head " out of the grippers which hold it in the ring mould. The Specification, as open to inspection under Sect. 91 (3) (a), describes also the construction of the pressing-mechanism, the ring moulds, the finishing moulds, and other details of the complete machine. This subject-matter does not appear in the Specification as accepted.

Patent GB-1036689-A (GB)
Title: Settle blowhead and baffle attachment for glassware forming machine
IPC: C03B9/16
Filed: 1965-06-09
Abstract: A machine for blowing an inverted glassware parison in a mould having a top opening for receiving a gob of molten glass, comprises a hollow blowhead 26 (Fig. 1, not shown) supported for movement out of and into engagement with a mould 34 around said top opening 36, a baffle 38 movable in the blowhead into a closed position in opening 36 for the blowing of the parison and out of the closed position to admit air under pressure into the mould to settle the gob of glass, means 46, 48 biasing the baffle 38 out of the closed position to form a passage for the settle-blow air, conduit means 66, 56 (Figs. 2 and 3, not shown) connecting the passage 40 to air under pressure and including a normally open first valve 54 and a normally closed second valve 58, and means selectively operable only when the blowhead is engaged with the mould to close the baffle 38 and to close the first valve 54, the valve 54 being adapted to remain closed due to the pressure of air in the conduit until the pressure is dissipated by the closing of the second valve 58. A blowhead 26, with a baffle 38 slidably mounted therein, is supported upon an arm 16 attached to a post 10.  When the blowhead is moved into engagement with a funnel 32 of mould 34 an arm 80 on the post 10 depresses a piston 82 against a spring 84 in the valve 58. This opens said valve and allows air to pass to valve 54, which is open, and thus through the passage 40 to settle blow the gob of glass in the mould 34.  An arm 52 is then lowered and engages a pin 46 attached to baffle 38 and causes the baffle to be depressed against a spring 48 and close off the opening 36 in the top of mould 34.  Simultaneously a bolt 70 on arm 52 depresses a piston 66 against a spring 76 in the valve 54 so that the piston rests on a seating 74 causing the air to the mould 34 to be cut off.  The air pressure behind the piston head 72 maintains the valve closed.  The parison is now counterblown in the mould.  The arm 52 is then retracted allowing the baffle 38 to be biased away from the opening 36.  The blowhead is then lifted away from the mould and simultaneously the arm 80 releases the piston 82 of valve 58 which then closes.  This cuts off air to valve 54 releasing the pressure behind piston 66 so that the piston 66 can be pushed upwardly by spring 76 thus opening valve 54.

Title: Improvements in and in the manufacture of grid resistances
IPC: H01C3/10
Filed: 1921-12-16
Abstract: 195,653. Satchwell, L. Dec. 16, 1921. Resistance grids.-In a resistance of the grid type, the bars of each component grid are splayed apart by and clamped upon an insulated member threaded between them at about the middle of their length. The insulated member employed consists of a strip of metal folded upon itself and arranged edgewise between strips of mica with flat supporting strips of sheet metal, as described in Specification 191,934; similar members may also be used to separate adjacent grids. Alternate bars of the grid may be bent out of their plane to receive the splaying separator, or as shown in Fig. 2, each bar may have an approximately central bend, adjacent bars in opposite directions, to receive the insulated member 13. When the component grids are made separately instead of from a continuous strip of metal, adjacent grid ends may be connected by bending them at right-angles and securing them by bolts 11, Figs. 1 and 2, or by welding etc.; alternatively, the separators may be extended beyond the length of the grids and the grid ends doubled around the extension 12, as at 16, and connected together or to control apparatus by bolts passing through the separator. To prevent longitudinal movement or straining of the bars of the grids, each bar is stamped with an approximately central recess of the same width as the separator which engages therein. The grids may be formed by cutting, stamping or bending a length of conductor into the required form. Preferably the grids are made by stamping a number of transverse slots in a sheet of metal, the slots extending to within a short distance of each edge. Adjacent bars are bent in opposite directions, the splaying insulators are introduced and the grids are mounted upon insulated bolts 10 and clamped by nuts 8 between end-plates 9. The slots are then extended to their respective edges, adjacent slots being extended in opposite directions, and the neighbouring junction ends of bars are given a twist to separate them further.

Title: Improvements in control valves for air braking systems
Inventor: EATON MAURICE BARRY
IPC: B60T8/18
Filed: 1963-07-17
Abstract: 1,034,828. Air brakes; valves. GIRLING Ltd. July 3, 1964 [July 17, 1963], No. 25355/63. Headings F2F and F2V. A vehicle braking system includes a control valve having a pressure-sensitive control member of which the effective area is variable with the load on the vehicle to regulate automatically the pressure of fluid supplied to the brake cylinders, the member controlling the area being normally held out of engagement with the means responsive to vehicle loading variations and urged into engagement with that means only at brake application. Air from the driver's valve enters port 14 and passes through channel 20 to act between the variable area diaphragm 27 and the control member 28 to overcome spring 38 and bring rod 29 into engagement with the said load responsive means. At the same time piston 26 is moved upwards to open valve 21, 22 and allow air to reach the brake supply port 24. Air from this port also passes through passage 32 to act above the diaphragm 31 until the piston is maintained balanced between the downward force on diaphragm 31 and that on the inner side of the variable area diaphragm 27. The shape of the lower face of piston 26 determines the convoluted shape of the diaphragm and thus its effective area. Increase or decrease in vehicle load moves rod 29 up or down, respectively, to increase or decrease the said effective area, the piston 26 consequentially rising or falling to open valve 21, 22 or valve 34, 35 to respectively increase or decrease the pressure in the brake cylinder. In a second embodiment (Fig. 3, not shown) the part 33 is extended upwards to abut the valve seat 21 and there perform the function of valve 34, 35. In a third embodiment (Fig. 4, not shown) a port connected to the driver's valve is directly connected to the chamber below diaphragm 27 and the valve controls the connection between a reservoir and the brake cylinder.
