Patent number: 4846370Abstract: Systems are described for using multiple closely-packed spheres. In one system for passing fluid, a multiplicity of spheres lie within a container, with all of the spheres having the same outside diameter and with the spheres being closely nested in one another to create multiple interstitial passages of a known size and configuration and smooth walls. The container has an inlet and outlet for passing fluid through the interstitial passages formed between the nested spheres. The small interstitial passages can be used to filter out material, especially biological material such as cells in a fluid, where the cells can be easily destroyed if passed across sharp edges. The outer surface of the spheres can contain a material that absorbs a constitutent in the flowing fluid, such as a particular contamination gas, or can contain a catalyst to chemically react the fluid passing therethrough, the use of multiple small spheres assuring a large area of contact of these surfaces of the spheres with the fluid.Type: GrantFiled: January 23, 1985Date of Patent: July 11, 1989Assignee: California Institute of TechnologyInventors: Daniel D. Elleman, Taylor G. Wang

Patent number: 4805805Abstract: A tube dispenser utilizes a ratchet actuated pusher for squeezing the contents from a tube. In a first embodiment, a tube is supported on a support plate with a nozzle of the tube extending through an aperture formed in an end wall connected to the support plate. A handle, mounted on an opposite end wall, has an attached ratchet actuation lever. A toothed rod extends through an aperture in the end wall adjacent the handle. A pair of frame rods extend betwen the end walls. By squeezing the ratchet actuation lever, the pusher is caused to advance along the support plate, squeezing the tube walls between the pusher and the support plate. Three different configurations of the pusher are disclosed. The pusher may be formed as a cylindrical bar, a right angle channel, or as a plurality of rotatable rollers. In a second embodiment, the tube is supported within a receptacle, with a nozzle of the tube extending through an aperture in an end wall of the receptacle.Type: GrantFiled: February 19, 1988Date of Patent: February 21, 1989Inventor: Glen D.

Patent number: 4508242Abstract: The toothpaste dispensing apparatus of my invention comprises an enclosure which houses multiple separate tube holders for holding the tubes of paste. It, also, contains a reversible motor connected by a worm screw to a holder containing a pair of movable rollers for dispensing tooth paste, shaving cream, etc. from any of its multiple positions. The paste is discharged at the bottom of the inner tube holder by a squeezing pressure exerted upon the tube by the pair of rollers which moves downward over the inner tube holder. This device is equipped with a switch for automatically reversing the downward direction of the rollers when the contents of the tube have been exhausted. A most unique feature is the provision for housing several tubes and the selector knob, which allows the operator to choose either one of the several tubes on which to operate without having to dismantle or load or unload the device.Type: GrantFiled: October 21, 1982Date of Patent: April 2, 1985Inventor: Edward B.

Patent number: 4405062Abstract: A flexible tube dispensing device designed for use with flexible tubes containing pastes, gels, liquids and certain powders. In use the dispensing device opens to accommodate the end of a flexible tube in which is contained a product in paste or other form which may be dispensed by squeezing the tube. Once the tube is inserted, squeezing of a pair of dispensing jaws of the device squeezes the tube to dispense the product and causes the device to advance along the tube as the product is dispensed. This allows almost complete evacuation of the tube contents and dispensing of relatively uniform amounts of contents each time the device is squeezed.Type: GrantFiled: October 19, 1981Date of Patent: September 20, 1983Inventor: Eraine J. Tschida, Sr.
