  • Patent number: 5374864
    Abstract: A series of improved electron multipliers is shown which are capable of reducing the number of bombardments per unit area. In the preferred embodiment, the inner channel is significantly increased in surface area over that surface area of present-day multipliers. Because the surface area is increased, for the same charge throughout, the number of electron bombardments per unit area is decreased. Since the number of bombardments per unit area is reduced, there is less degradation on the inner surface of the channel and hence the device lifetime is also increased.

  • Patent number: 5374827
    Abstract: An electron multiplier is disclosed having separate detector and conversion dynode elements. A single power supply external to the electron multiplier is used to bias the detector element. A DC-to-DC voltage converter within the electron multiplier is responsive to the detector bias voltage for converting this voltage to a greater value that is used to bias the conversion dynode.

  • Patent number: 5030878
    Abstract: A segmented electron multiplier is disclosed with front and rear sections. The sections are specially designed so that the length of the rear section compared to the length of the front section is no less than 4:1. This permits multiple replacements of the rear section, after the multiplier wears out, without any unsatisfactory drop in the overall electrical gain produced by the repaired device. In the preferred embodiment, the front portion is a funnel having a tubular stem, and the rear portion is a straight tube with a cylindrical helical inner channel. The length-to-length split is 5:1, which theoretically permits up to six or seven replacements of the rear section before unsatisfactory gain occurs.

  • Patent number: 4738854
    Abstract: Comestible compositions such as chewing gum containing freely dispersed L-aspartic acid sweetening agent derivative, moisture, and optionally, a manufacturing heat history of at least 115.degree. F., are rendered storage stable relative to the retention of recoverable levels of the L-aspartic acid derivative by adding freely dispersed hydrogenated starch hydrolysate thereto, thereby allowing for the effective use of relatively low levels of such L-aspartic acid derivative therein.

  • Patent number: 4352825
    Abstract: A coextruded chewing gum is provided which includes an extruded center portion surrounded by and bonded to an extruded outer shell portion. The center portion of the coextruded chewing gum will be of a generally soft consistency, substantially softer than that ordinarily employed in chewing gums of conventional structure, while the outer shell portion will provide a protective layer or coating for the core portion to inhibit sweating and stickiness and thereby allow for use of conventional wrapping machines.

  • Patent number: 4352823
    Abstract: A coextruded chewing gum is provided which includes an extruded center portion surrounded by and bonded to an extruded outer shell portion. The center portion of the coextruded chewing gum formed of a non-SBR gum, will be of a generally soft consistency, a moisture content of at least about 5% up to about 10% by weight of the core, while the outer shell portion will provide a protective layer or coating for the core portion to inhibit sweating and stickiness and thereby allow for use of conventional wrapping machines.

  • Patent number: 4271197
    Abstract: A chewing gum is provided which has improved softness and flexibility retention, and prolonged shelf life and contains as a plasticizer and sweetener a combination of a hydrogenated starch hydrolysate and sorbitol, and optionally, mannitol, glycerin, and/or gum arabic. The above chewing gum has been found to have excellent extrudability properties and may be used in making sugarless bubble gums, standard sugarless gums as well as center-filled gums.

  • Patent number: 4100301
    Abstract: A chewing gum is provided which contains non-dusting colorants in the form of lake colors dispersed in an animal or vegetable type fatty acid or oil vehicle substantially. The gum may also contain artificial sweetners thereof.
