Title: Improvements in apparatus for conveying glass ware into annealing leers
IPC: C03B35/06
Filed: 1924-02-04
Abstract: 230,598. Williams, P. Q. Feb. 4, 1924. Charging. - Glass ware is carried from a bottle-making machine and is spread upon the conveyer of an annealing leer by a conveyer mounted on an oscillating pivoted frame. An endless conveyer 21 is carried on a frame over sprockets 23, 24, the latter of which is driven from a motor 33 on a platform 28 adjustable by a screw 30. The conveyer is 'supported by rollers travelling on longitudinal angle irons 38 mounted on opposite sides of the frame. The forward end of the conveyer frame is mounted on a support 49 about which the frame is oscillated by a pinion 76, driven from a motor 69, attached to a platform 68, and engaging a stationary rack 77 carried by a channel member 78 adjustably secured to the machine frame. Air is supplied through the support 49 to longitudinal chambers 55 terminating in horizontal nozzles disposed along the side of the conveyer. Adjustable side-bars 61 guide the ware along the conveyer and carry deflectors 66 which move the ware laterally. The platform 68 is secured to the rear end of the frame and is supported by rollers 80 engaging the channel 78. Lugs 86, 87 on the latter co-operate with the arm of a switch for reversing the motor 69. A leer conveyer 88, actuated intermittently by an electromotor 89 energized by the closing of contacts on the frame, is contained between side walls 99, 100. A sliding door 102 provided with an opening 103 for the ware is arranged in front of the leer. Within the leer is arranged an inclined retaining wall 109 for supporting a pile of ware. An angularly adjustable shoot 112 is mounted on the rear end of the frame and is fitted with a roller 118 over which the bottles are fed, any broken portions being discharged. Ware is fed to the conveyer 21 neck first down a shoot 119 with a short side 121 and a curved side 122, 123, panel bottles by this arrangement being automatically turned on edge. In operation, the ware is discharged in a plastic state from a bottle-making machine down the shoot 119 on to the conveyer 21. The air from the nozzles cools the bottles and rolls round bottles across the belt, the deflectors 66 displacing panel bottles to prevent them sticking. The conveyer 21 delivers the ware to the shoot 112 discharging to the retaining wall 109. During this time the frame and its conveyer 21 are moved round a support until at the limit of travel the reversing switch arm is actuated to reverse the motor 69 and the motion of the frame, and the circuit for the motor 89 is closed for moving the leer conveyer.

Abstract: 1,128,767. Magnetic storage apparatus. KERAMISCHE WERKE HERMSDORF VEB. 21 Jan., 1966, No. 2911/66. Heading H3B. In a method of producing a magnetic core matrix a plurality of cores are held in a row, wires are threaded through the cores in the direction of the row, by means of nozzle-shaped guide pieces disposed between the cores either prior to or after pushing the cores on to fixed threading needles 2, the threaded cores are displaced over the needles on to wires 9 connected to the needles, and the core arrangement is displaced along the wires into a desired raster grid pattern. The threading needles 2 are equal in number to the number of columns of the matrix. In the arrangement of Fig. 13A the cores are threaded in the direction of the row prior to threading on needles 2 and are positioned in core receptacle 30 from feeder 20 and are threaded at position 8. In the arrangement of Fig. 2 (not shown) the threading point 8 lies between the clamps 3.1, 3.2 and the cores are first pushed on to the threading needle 2 over a slide path by a vibratory conveyer. After being threaded on needles 2 clamp 3.2 is opened and the cores are moved into the threading position between the clamps and held in position by two combs, Fig. 4 (not shown), which are placed on the threading needles 2 and displaced in relation to one another. In Fig. 5 (not shown), an angle is mounted rotatably on a base-plate to align and secure the cores in the threading position, a plate being mounted on the angle against which the individual cores rest. In another arrangement, Fig. 6 (not shown), two magnets are employed to position and hold the cores. The cores may be held in position by the threading needles 2 themselves which are suitably shaped; Fig. 7 (not shown). After the cores have been positioned and held in the threading station guide pieces 4, Fig. 8, are provided to guide the selecting wires through the cores after which step the wires are secured in clips 5 constructed as testing terminals. On the completion of this threading step the cores 7 together with the clips 5 are transferred to the weaving station 11 by opening the clamps 3.1, 3.2 by way of the tensioning wires 9 joined to the needles 2. When the space 11 has been filled with the required number of core arrangements all wires are released from their clamps or connections 2, 5, 6 and the core arrangements are placed in matrix frames, Figs. 14, 15 (not shown). Before or after the core arrangements are placed in the matrix frames a read line is drawn in by hand and an inhibit line is formed by soldering together the wires of adjacent rows or is drawn in by hand in one piece.

Title: Improvements in sighting devices
IPC: F41G5/22
Filed: 1917-03-02
Abstract: 262,188. Henderson, J. B. March 2, 1917. Sights and methods of sighting; ordnance, discharging by means external to breech mechanism. -Relates to sighting devices, for use on moving platforms such as ships or aircraft, of the kind in which the sight controls the operation of a power circuit or member. The invention is specially applicable to gun sights combined with automatic firing gear for the gun comprising a switch which is closed by the angular movement of the ship, but is also applicable to other devices such as bomb sights and photographic sights. According to the invention, an angular advance of the switch or of the line of sight proportional to the velocity of roll is produced by an elastically constrained gyroscope which is forced to partake, of the angular motion of the platform. As shown in Fig. 1, the firing switch comprises two contact plates 1, 2 and a dumbbell roller 4 carried by a switch lever 8. The contact plates are carried by a lever 10 pivoted on a ball bearing 11 concentric with the pivot 9 of the switch lever 8. The lever 10 carries at its other end a small gyroscope 12, and is constrained relatively to the rest of the sight by two springs 15, 16 attached to a pin 17 on the lever and two pins 18, 19 on the frame of the sight. The gyro case is also connected by a rod 20 to a pin 22 on the frame of the sight. When the sight rolls about the axis 9 the gyro case pitches about the trunnion axis 13 and thereby advances the lever 10 through an angle proportional to the velocity of roll. In a modification, Fig. 2, the gyroscope 12 is connected to a thick plate of glass 26, interposed in the optical system of a sighting telescope 23, 24. The gyro causes the plate 26 to tilt through an angle proportional to the velocity of roll and thereby tilts the line of. sight up or down. in another modification, a similar result is obtained by a thin prism moved backwards and forwards along the line of collimation of the telescope.

Abstract: 744,309. Steering vehicles. BURMAN & SONS, Ltd., and BRIGGS, W. H. April 29, 1954 [Feb. 5, 1953], No. 3238/53. Class 79 (5). In a vehicle steering mechanism of the kind comprising a driver-operated rotatable screw b, a nut c movable longitudinally along the screw, and means to transmit motion from the nut to the steerable wheels, a fluid-actuated power resistor is provided of which the cylinder j moves with the nut, the piston i is formed on or secured to the screw, and a control valve r is operable in response to an initial movement of the nut. In one embodiment, steering column a is formed with the screw b and rotation of the column advances the cylinder over the piston i. The movement of the cylinder rotates a shaft f which carries at its other end an arm h connected to an intermediate point of an arm t, the latter being connected at one end to the steerable wheels and, at the other end, to a piston valve r which works in a sleeve seat formed in arm h. There is a pressure fluid inlet p to the valve seat, two outlets o which lead to the two ends of cylinder j, and two outlets to exhaust at the ends of the seat. Due to the negative lap of the lands of the piston valve, there is a constant circulation of fluid to the two ends of the cylinder when the valve is in neutral position. The initial movement of the steering column causes movement of the valve to apply a pressure differential across the piston i and so assist the movement of the nut along the screw. In another embodiment the nut c constitutes the valve, and the slight rotary movement it makes on the initial turning movement of the steering column serves to direct the pressure fluid to the appropriate end of the cylinder.
