  • Patent number: RE29042
    Abstract: A distributor for comminuted tobacco wherein a first conveyor, such as a carded drum, an endless apron or a pneumatic conveyor, supplies tobacco at a variable rate into the path of orbital movement of bristles on a rapidly rotating accelerating device. The bristles propel the particles of tobacco onto a narrow foraminous transporting belt which travels in a horizontal channel and accumulates a dense tobacco stream which is transported past a trimming device and into the wrapping mechanism of a cigarette rod making machine. The accelerating device is driven by a separate motor so that the peripheral speed of its bristles exceeds the speed of tobacco travel on the first conveyor. The stream is attracted to the transporting conveyor by suction, and the accelerating device is placed sufficiently close to the channel to insure that, during impact against the transporting conveyor or against the layer of tobacco thereon, the kinetic energy of all or nearly all tobacco particles is substantially identical.

  • Patent number: RE29045
    Abstract: A method of blow molding plastic articles in two blowing stages. A freely extruded pendant tubular parison is first blown into a pre-form, then the pre-form, while at the temperature most conductive to orientation, is blown to its final configuration. By performing certain operations on the pre-form prior to the final blowing step, improved products can be made. For example, by pinching shut a portion of the pre-form, handled containers can be made on a free extrusion blow molding machine. By stretching the pre-form prior to final blowing, containers of increased top-load or stacking capabilities can be made. .Iadd.This application is a re-issue of U.S. Pat. 3,781,395, issued Dec. 25, 1973, matured from U.S. Pat. application Ser.

  • Patent number: RE29048
    Abstract: A circuit for providing a regulated square wave output voltage and a regulated DC output voltage or both. An AC source energizes a switching circuit, having a variable switching rate, which connects a capacitor in voltage clamping relationship to an AC load for both half cycles of the AC voltage thereacross. This switching rate is controlled in accordance with the time accumulation of an electrical quantity, in the present instance the voltage across the AC load. The DC voltage across the capacitor attains a predetermined equilibrium value when the frequency of the AC output voltage is equal to the frequency of the AC source. If the DC capacitor voltage and the AC output voltage derived therefrom deviate from their equilibrium values, as, for example, because of a change in the level of load current, there occur transient changes in the switching rate of the switching circuit which result in changes in the phase displacement between the AC input voltage and the AC output voltage.
