Title: Filled sack sewing apparatus
IPC: B65B51/07
Filed: 1921-05-28
Abstract: 180,212. Fairweather, W., (Singer Manufacturing Co.). May 28, 1921. Sack-sewing machines.-A filled-sack sewing- machine comprises a motor-driven conveyer 30, 31, work-operated means for actuating the sewing-mechanism 10 from a second motor 12, and emergency mechanism for stopping the conveyer and sewing mechanisms simultaneously. A conveyer frame 14, vertically adjustable on screw rods 74, 75 which are actuated by handles 80 through connections 76 - - 79, carries conveyer belts 30, 31 on rollers 54, 56, the former of which is driven by gearing from a shaft 39. A clutch 43, 41 can be actuated by a lever 44 to connect the shaft 39 to a loose pulley 40 driven by a motor 29. The sewing-machine 10 carries a bracket 81, 82, on which is pivoted a weighted lever 83 carrying a belt fork 84, and a pulley-brake 85'. Bars 89, arranged between the conveyer belts, are connected to crank-arms 91, 96 on roller spindles 92, 97, the latter of which also carries a crank-arm 98, to which is joined a flexible member 99, passing round elements 86 - - 88, through the end of a lever 101, and supporting a weight 103. The other end of the lever 101 is connected by a chain 106 to a crank-arm 107 on the shaft 58, on which is mounted a starting-handle 61. When the machine is stationary, Figs. 1 and 3, the lever 101 is in a raised position and a spring 100 on the lever, which always grips the connection 99, provides sufficient slack in the connection to allow the belt-shifting lever 83 to assume its stop-motion position, and the trip-bars 89 to be lowered under their own weight. In operation, the motors 12, 20 are separately started, and the handle 61 is pulled to the left, Fig. 1, to rotate a vertical rod 73, through connections 68 - - 71, to shift the lever 44 and to connect the conveyer to its motor. The same movement of the handle allows the lever 101 to drop, so that the trip-bars 89 are raised into operative position, the lever 83 not being affected. A filled rack travelling along the conveyer depresses the trip-bars 89, so that the connection 99 actuates the lever 83 to shift the belt 13 from the loose to the fast pulley of the sewing-machine. When the sack rides off the tip-bars, the weight 85 takes control, disconnecting the sewing-mechanism and raising the tripbars. By shitting the handle 61 to the right during running, the conveyer mechanism can be unclutched, and the lever 101 is raised so that the spring 100 produces slack in the connection 99; the slack produced is taken up by the lever 83, thus stopping the sewing-mechanism.

Filed: 1948-06-03
Abstract: 653,189. Aromatic speed control systems. CLEMENT, G., VAGLIO, F., and CARIGNAN, M. June 3, 1948, No. 14997. Convention date, June 3, 1947. Drawings to Specification. [Class 38 (iv)] [Also in Groups XXXVIII, XL (b) and XL (c)] In sound film apparatus, the connection between the camera and microphone unit and the sound recorder unit is effected by beamed ultra-high frequency radio waves which are modulated by the sound and by signals for synchronizing the motors of the camera and the sound recorder. Synchronizing pulses are provided at the camera unit by means of a perforated disc rotated by the current generator feeding the motor, which is placed between a light source and a photo-electric cell, the resulting impulses being used to modulate a supersonic frequency which in turn is used to modulate the high-frequency carrier. A train of impulses proportional to the speed of the recorder motor is produced at the sound recorder unit in a similar way, which is mixed with the incoming pulses from the radio receiver to provide a beat frequency. The beat frequency is applied to a frequency discriminator which provides a positive or negative connecting voltage as the beat frequency increases or decreases from a predetermined value. The correcting voltage is used to vary a resistance which controls the field of the generator at the sound recorder unit, so that the speeds of the motors at the camera and recorder units are synchronized.

Abstract: 870,614. Thermionic valves. STANDARD TELEPHONES & CABLES Ltd. May 15, 1958, No. 15603/58. Class 39(1). A thermionic valve has an indirectly heated cathode mounted by a tubular metal support member 8, Fig. 2, and a getter comprising continuously operable getting material such as a refractory metal gauze 12 coated with titanium or zirconium mounted within the tubular member 13 and extending over a region where the temperature at one end of the region is 800‹C. and at the other end of the region is 400‹C. The cathode 7 is planar, its heater 9 is mounted on a central conducting support 11 coaxial with 8 and the getter 12 is secured to the central support 11. It is required for the purpose of absorbing hydrogen and carbon monoxide; since the temperatures for maximum absorption of these gases are different the design is such that a temperature gradient exists along the getter 12, i.e. 400‹C. at the lower and 800‹C. at the upper end adjacent the heater which is at 1500‹C The optimum temperatures for absorption by hydrogen and carbon monoxide lie within this range and so different parts of the getter are most effective to absorb these two gases. The heater 9 is a planar coil the inner end of which is connected to central leadsupport 11 and the outer end of which is connected to the heater cup 10 which together with 8 acts as the return lead for the heater. The cathode 7 is a cup coated on its planar surface with emissive material and a heater cup 10 fits inside it. The cathode support sleeve has holes communicating with   the remainder of the valve to enable the getter 12 to absorb gas from the entire space inside the valve. The cathode is incorporated in a thermionic valve triode of otherwise known construction, Fig. 1 (not shown) in which. the anode- and fine wire mesh control grid have supports of generally cup-disc form sealed together by glass cylinders. In outgassing the cathode is run 200‹C.-300‹C. higher than normal operating temperature; this enables the getter to be outgassed.
