Abstract: 1,222,629. Making gears; forging; stamping; working at specified temperatures. INTERNATIONAL BUSINESS MACHINES CORP. 18 Nov., 1969 [13 Dec., 1968], No. 56312/69. Headings B3A, B3H, B3Q and B3V. [Also in Division C7]  A superplastic metal blank is moulded in a die which is heated to a temperature exceeding that at which the metal loses its superplasticity. In one embodiment the blank P<SP>1</SP> is forged in an electrically heated die 10 closed by a cover-plate 16. The die is steel and the blank is 78% zinc, 22% aluminium alloy. The cover may be heated and insulated from the die. The blank is made superplastic by homogenization at 600 F., water quenching and heating to 500- 520 F. The die is heated to 610-630 F. The blank may be forged into a gear-wheel. In an alternative embodiment the blank is a disc B 1  which is vacuum formed in a heated die 40. The shaped blank is left in the die to heat it and remove the superplasticity and then ejected and air cooled.

Abstract: 1,242,288. Spray carburetters. NISSAN MOTOR CO. Ltd. Dec.4, 1968 [March 30, 1968], No.57538/68. Heading F1B. An air chamber 13 in the idling system of a carburetter receiving air through an orifice 12 is connected to the main induction passage downstream of the butterfly valve 10 through a valve 27 and air is fed through orifices 14 and 15 to mix with fuel flowing through a passage 17 for passage to slow running and idling ports 20 and 21 in the main induction passage. On overrunning the valve 27 is opened by the vacuum downstream of the butterfly valve 10 and air flows through the conduit 23 and orifice 24. Simultaneously the pressure in the chamber 13 falls and the flow of air through the orifices 14 and 15 is reduced to produce a richer mixture for delivery through the ports 20 and 21. In a further embodiment, Fig. 5 (not shown), the air chamber (13<SP>1</SP>) is connected to the main induction passage downstream of the butterfly valve through a solenoid actuated valve (32). The valve solenoid is energized under the control of a diaphragm switch 34 subject to the intake manifold vacuum. Air to mix with fuel in the idling system flows through one orifice (14) communicating directly with the atmosphere and a second orifice (15) communicating with the atmosphere via the air chamber (13<SP>1</SP>) and an orifice (12<SP>1</SP>).

Title: Improvements in and relating to a hydraulic power lifting means
IPC: A01B63/10
Filed: 1970-12-29
Abstract: 1293998 Tractor power lift mechanisms ROBERT BOSCH GmbH 29 Dec 1970 [21 Feb 1970] 61674/70 Heading A1P The height and attitude of a semi-trailed implement 26 are independently adjustable by hydraulic rams 16, 67 on the tractor power lift mechanism 19-25 and on the rear support 71 respectively. The front of the implement is connected to draw bar 24 and is raised by lift link 22 connected to lift arm 19 on rocker shaft 20 when lever 47 sets valve system 6 to direct hydraulic fluid to ram 16 having its piston 17 connected to shaft 19. Simultaneously hydraulic fluid is expelled from a cylinder 76 since its piston 77 is connected to lift arm 20 on the opposite side of rocker shaft 20 to the piston 17. This fluid passes through coupling 74 and pipe line 66 into ram 67 connected between the implement and support bracket 71 thereby raising the rear of the implement in sympathy with the front. When the implement is lowered its attitude is similarly maintained. The attitude may be adjusted by changing the relative height of the rear of the implement by lever 63 setting valve system 8 to direct hydraulic fluid to or from ram 67 through pipeline 66. Automatic draught control is achieved by draw bar 24 pivotally mounted on lever 34 acting in known manner on valve system 6 via links 36, 39 and lever 38 to raise or lower the implement until the required draught force set by lever 47 is achieved. In a second embodiment Fig. 2 (not shown) the ram 16 is replaced by a double-chambered ram (85) having its second fluid chamber (87) connected to serve the purpose of cylinder 76 which is omitted. In another embodiment Fig. 2 (not shown) cylinders 76 and 16 are replaced by the two halves of a double-acting cylinder (85). Further emobidments are arranged to delay operation of rear ram 67 so that the ploughshares or other parts of the implement leave or enter the ground in turn and at the same distance from the end of a run. In the embodiment of Fig. 3 when lift arm 19 is turned clockwise to lower the front end of the implement its guide pin 101 begins to slide up slot 100 of link 99 which is slidably carried by piston 94 and urged upwards by spring 97. The weight of the rear of the implement forces fluid from cylinder 67 through check valve 93 into chamber 90 to raise piston 94 and allow the rear of the implement to fall. This action is delayed since the only outlet for the fluid in the second chamber 102 is through restriction 104. Some time after lift arm 19 has stopped the piston catches up with it and the implement becomes level. When the implement is raised pin 101 presses link 99 down and compresses spring 97 until the pressure transferred to piston 94 is great enough to move it downwards and raise the rear of the implement. Fluid flows easily through check valve 106 into chamber 102 but the restriction 97 in the outlet to chamber 90 assists in delaying the operation of ram 67. In the embodiment of Fig. 4 (not shown) the spring is replaced by a hydro-pneumatic accumulator (110) opening into chamber 90.

Abstract: A dual-standard display system with a common light pen has a raster-scan display TD and a cursive display CD, each with its own display drive circuit RD and LD respectively. A single light pen LP is connected to a switch control SC responsive to the repetition rate of light pen output signals.

The switch control SC may include a "window generator" comprising a counter, a decoder and a line-frequency clock generator. A gate responsive to the output of the window generator and to the output of the pen causes a monostable to assume its unstable state and to operate switch SM thus connecting the output of the pen to a raster-interrupt circuit RI whenever the pen is applied to a raster-scanned image. Otherwise the output is connected to the cursive-interrupt circuit CI. <IMAGE>

Abstract: A tire building apparatus is provided having an improved mechanism for turning up the plies of the tire carcass and wrapping them around each tire bead ring. The mechanism is designed so that it can also be used to apply the sidewall pads to the expanded carcass of a radial tire. The improved mechanism includes a bladder that has a molded conical portion in its outer fold adjacent the building drum. This conical portion extends very close to the bead ring positioned adjacent the carcass at the sides of the drum shoulders. The improved mechanism also includes a control ring insert placed inside said bladder and radially inwardly from the conical portion of the outer bladder fold. When the bladder is inflated to wrap the carcass plies around the bead ring, the control ring insert and the molded conical portion of the outer bladder fold combine to provide an improved, tighter wrapping of the carcass plies around the bead ring. They also provide a smoother, more accurate positioning of a sidewall pad to an expanded radial tire carcass when the mechanism is employed for that purpose. There is also provided a method and apparatus for molding a bladder having a conical portion in its outer fold.
