Title: Improvements in or in connection with Machinery or Apparatus for the Manufacture of Bottles and other Blown Glassware.
Inventor: ROIRANT EMILE
IPC: C03B7/20
Filed: 1919-03-10
Abstract: 134,152. Roirant, E. Dec. 2, 1918, [Convention date]. Blowing; delivering molten metal; cutting-off excess of metal.-Relates to automatic apparatus for the manufacture of glass bottles. The movements of the apparatus are timed by adjustable cams on a shaft 75 connected to a continuously rotating shaft 86 by a clutch 104, which is engaged when a finished bottle is ready for discharge, and is disengaged as soon as the next bottle has been blown. The blown bottle remains in the mould during the period of disengagement of the clutch 104. To allow this period of rest to be varied, a variable-speed friction-disk arrangement 93, 94 is used. The disk 94 has a pin 98 which trips a lever 99, and so engages the clutch 104 by means of a rod 100 and bell-crank lever 101. When the blowing is complete, the roller R on the lever 101 enters a recess in a cam 106 and disengages the clutch 104, which remains out until the pin 98 again strikes the lever 99. By this arrangement, the period of rest in the blowing- mould can be varied without altering the timing of the other operations. A ladle 11 is charged at the opening 3 and swung about the shaft 7 to a position below the parison mould by a pinion 12 and toothed arc 13. The adjustment of a teloscopic rod 15, connecting the arc 13 with a crank on the shaft 75, determines the length of the period of rest at the opening 3 and below the parison mould. The blowing-mould 33 and parison mould 39 are hinged on pins 35, 41 respectively, and work in a manner similar to that described in Specification 112,007. Cam-operated compressed-air and suction valves 109 are connected by a pipe 60 with the neck mould. The cut-off knife 69 is worked by a spring 76 and cams on the shaft 75.

Title: Improvements in vermin traps of the break-back type
IPC: A01M23/30
Filed: 1922-03-02
Abstract: 198,743. Lever, H. E. March 2, 1922. Animal traps.-In a breakback trap of the kind in which the break-back bar has a cranked portion acted upon by a spring which is released by an animal treading upon a pivotal platform, the whole of the tripping-mechanism is concealed beneth the base, of the trap. The bar E, which is made from a single rod, has a cranked portion D and is pivoted in the down-turned sides of the metal base A. A spring F connected with the part D and the end Q of the base, which end is V-shaped in plan, tends in the set position to turn the crank D upwards. Pivoted at H is a platform B occupying a hole in the base A and pivotally carrying at K a trip rod C which is pressed against the undersurface of the base A so that the end R becomes a fulcrum. An animal treading on the platform B thus forces the crank D down so that the line of action of the spring passes below the pivots of the bar E, enabling the spring to force this bar down on to the platform. The downward and upward movements of the platform B are limited by stops, and the position of the spring F may be adjusted up and down the end Q, which has a slot through which the end of the spring passes. In a modification the end R of the rod C has a V-shaped portion in order to make the trap more sensitive.

Abstract: 1,049,844. Cinematography. FUJI SHASHIN FILM KABUSHIKI KAISHA. Feb. 12, 1965, No. 6294/65. Heading G2E. Means for automatically adjusting an exposure control system of a cine camera, to adapt it to the sensitivity of the film to be exposed, is operated by means of a member sensing the length of a slot provided in the film magazine. On inserting the magazine in a camera, a pin 10 enters an arcuate slot provided in the side wall of the magazine and concentric with a film spool axis. As the camera casing is closed by locking means 24, pin 22 is moved to the right. The resulting movement of bell-crank 18 is transmitted, by a pin 13 and slot connection, to plate 9. A spring 16 transmits the motion of plate 9 to co-axially mounted plate 8 and the plates move together as pin 10 rides along the length of the slot. When pin 10 reaches the end of the slot, plate 8 is brought to rest and spring 16 permits lost-motion between plates 8 and 9. Plate 8 thus carries sliding contacts 29, 30 into a position, determined by the length of the slot, in which the appropriate resistor 26 is connected in the exposure control circuit. In another form (Figs. 2 and 5, not shown), the slot is rectilinear. In a reversible magazine, twin slots may be provided (Fig. 3, not shown).

Abstract: 1522594 Axial-flow and mixed-flow compressors GENERAL MOTORS CORP 8 Feb 1973 [22 Feb 1972] 6318/73 Heading F1C A supersonic compressor blade cascade has each blade including a spanwise portion the crosssections of which are defined by at least four sides each deviating to the extent required from a straight line, each face of the blade being defined by at least two surfaces extending chordwise and spanwise of the blade with adjacent surfaces meeting at a lateral edge extending spanwise of the blade. The blade pitch, the stagger angle, and the cross-section of the blades are such that, with reference to Fig. 2, the compression wave 32 generated at the lateral edge 30 on the suction face of each blade 13 intersects the leading edge 26 of the next trailing blade, the leading edge shock wave 34 of each blade intersects the trailing edge 27 of the next leading blade and the trailing edge shock wave 36 of each blade intersects the lateral edge 28 on the pressure face of the next trailing blade, the faces being so directed downstream from each edge as to accord with the gas flow direction downstream of the waves and cancel the incident waves. The direction of rotation of the cascade is indicated by the arrow 14 and the directions of air-flow entering and leaving the cascade by the arrows 15 and 16, respectively. The blade cross-sections are shown as trapezoidal figures but in practise the sides of the cross-sections will be curved to some extent. The cascade shown in Fig. 5 differs in that the edge 30 defines a convexity rather than a concavity and generates an expansion wave 32' rather than a compression wave. Also a third surface 39 on the suction face is disposed between the trailing edge and a lateral edge 40, and the leading edge shock wave 34 intersects this lateral edge 40 instead of the trailing edge. Additional blade chord or closer blade setting is made possible by this arrangement.
