Abstract: A carding machine drive having an instantaneous braking system is illustrated wherein the driven main cylinder and carding components driven therefrom may be stopped instantaneously in about three seconds or less avoiding breakage of the web. A disk element is employed having opposed braking surfaces which are clampingly engaged by caliper means which are fixed to the card frame. The disk element has fixed connection and transverse alignment concentrically with the main cylinder. By driving carding components including the doffer directly from the main cylinder, simultaneous stopping thereof may be achieved. By utilizing conductor bars on component covers removal thereof automatically institutes braking.

Abstract: An assembly for supporting a cylindrical screen used for printing fabrics and the like. The assembly includes a screen supporting ring which may or may not have teeth on the perimeter thereof. A tensioning ring is nested in the screen supporting ring and is in axial alignment therewith. A bearing is carried between the tensioning ring and the screen supporting ring. Circular seals are carried on opposite sides of the bearing for protecting the bearing from contaminants and the like. Tension is imparted on the screen by pressing against the tensioning ring which forces the screen supporting ring outwardly.

Abstract: A method and apparatus for collecting, intensifying and storing solar energy which includes a hollow spherical vessel having a polished reflective interior surface. A window is provided in the wall of the vessel for allowing concentrated rays from the sun to enter into the interior of the vessel and be absorbed by a solar collector. The collector includes a substantially black (or a selective coating) heat absorbing surface carried by a spherical member which is centrally located within the spherical vessel. Heat absorbing media such as metal shots, are carried within the spherical member and change from a solid state to a liquid state as it absorbs the solar energy. The heat absorbing media cause radiant energy to be radiated radially in a symmetric beam pattern to the reflective vessel wall where the radiation is reflected back to the spherical member. The reflected radiant energy in conjunction with the sun's rays intensify the temperature of the heat absorbing media producing a thermal power supply.

Abstract: A device for feeding thin plastic film to and around a mandrel for forming a tubular package in which articles are deposited. The sheet material is advanced downwardly over the mandrel by means of a reciprocating collar which includes a unidirectional driving member. The tubular formed sheet material is cut and sealed by conventional sealing devices.

Abstract: An open loop control system is disclosed for controlling the production of a web or sliver on a carding machine so as to have a uniform weight per unit length. A novel sensing arrangement for the card input is disclosed wherein corrections to the input are made at the same mechanical plane and point in the feeding process as where the input is sensed to provide highly accurate control of the weight of the output.

Abstract: A method and apparatus for servicing a number of mutually adjacent spinning positions of an open-end spinning machine by means of a servicing apparatus which can move along the spinning positions. A travel drive is provided for the servicing apparatus for driving the servicing apparatus along the spinning machine when activated. Switches are connected to the travel drive for activating the travel drive responsive to being activated by an operator at a spinning station requiring service. A switch is also provided for de-activating the travel drive for halting the movement of the service apparatus in the neighborhood of the operator at the spinning station requiring service.

Abstract: Carriage attachment apparatus is disclosed for carrying a workpiece on an associated saw table whereby planar surfaces may be formed by sawing with common attachment between the carriage and a woodturning lathe being provided so that the sawed product is turned about the same rotational axis affording a high degree of symmetry.
