Abstract: CABLE TIE GUN                     Abstract of Disclosure The inventive cable tie gun uses simple slides and lever arms and does not require common linkages, toggles, or other complex mechanical actions that are subject to malfunc-tion.  Near the end of the tensioning slide travel, there is a mechanical interference between two moving parts (i.e. between a cable tensioning slide and a cable severing lever arm having a blade attached thereto.)  However, if the cable tie tension exceeds the pulling capability of the tensioning slide, one of the moving parts is immobilized and the interference does not occur.  Thereafter, the cable severing lever arm may take a full stroke and cut off the strap end while the tensioning slide is being held at midstroke posi-tion by the tension in the cable tie strap.  The performance of the cable tie gun is greatly improved by a correct choice of cam surfaces, whereby the parts help and do not oppose each other.

Abstract: ABSTRACT A ventilated cigarette uniquely designed to introduce volatile fla-voring agents such as menthol into the mainstream smoke of the cigarette with improved delivery rate and longer shelf life for the flavoring agent. The cigarette has a porous or perforated air permeable wrap encircling the filter plug impregnated with the volatile flavoring agent, enclosed in a per-forated or inherently porous air permeable tipping envelope. As the ciga-rette is smoked, air is drawn through the ventilation area of the tipping, through the flavor-impregnated filter plug wrap and into the filter carrying the volatile flavoring agent with it where it mixes with the smoke, thereby imparting flavor to the cigarette smoke. Since the flavor-impregnated plug wrap is tightly enclosed between the tipping envelope and filter plug, loss of the volatile flavoring agent is minimized, thereby enabling longer shelf life without reduction in flavor potency. Moreover, high delivery rates are achieved using minimum amounts of flavoring agent.

Abstract: ABSTRACT OF THE DISCLOSURE A unit set or assembly of several superimposed parts form a mailer without a stub, folded and detachable glue flaps on the top part underlying and being secured to the bottom part.  A three-part mailer construction is formed wherein the intermediate part is secured to the bottom part as the adhesive on one of the flaps extends through holes provided is the bottom part.  Removal of the top part therefore leaves the intermediate and bottom parts intact, or removal of the intermediate part leaves the top and bottom parts interconnected, or removal of the top and intermediate parts separates each of the parts from one another.  A minimum four-part mailer construction is also provided of superimposed parts with the first part having the folded and detachable glue flaps underlying and secured to the fourth part.  The third and fourth parts are provided with axially aligned holes respectively of different sizes, the smaller sizes fourth part holes defining masks rela-tive to the larger sized third part holes so that portions of the glue on the one of the flaps extend through such aligned holes.  Such glue portions are thereby confined to the smaller sizes of the third part holes so as to be spaced inwardly of the margins of the larger holes.  The first part may therefore be removed from the mailer while leaving the remaining parts intact, or separation of the second and fourth parts breaks the glue portions and frees the third part from the mailer while leaving the first and fourth parts interconnected, or removal of the first part together with separation of the second and third parts separates all the parts from one another.  The parts of both the three- and four part constructions may be single plies, or one of the intermediate parts thereof may be a return envelope.

Abstract: IMPROVEMENTS IN TELESCOPING SEATING SYSTEMS               ABSTRACT OF THE DISCLOSURE         A telescoping seating system has a plurality of row assemblies which may be extended for use or retracted to nested relation for storage.  Each row assembly includes a pair of laterally spaced posts extending upwardly and having the opposite ends thereof slanted in opposite directions with respect to each other.  In a preferred form, the posts extend upwardly and they are inclined inwardly so that all posts on each side of the structure are parallel, and the connection between the posts and decks are in vertical alignment on each side.  Thus, all row assemblies have a uniform center span.  End cantilever spans beyond the posts are also equal for all row assemblies.  Since the post/deck connections are the same for each row, all deck elements, such as risers, tread panels and seatboards are interchange-able; and they can be manufactured with uniformly spaced holes for fasteners, thereby facilitating manufacture and obviating any need to sort them when the structure is being erected on site.

Abstract: "ICE GUIDE FOR REFRIGERATOR WITH EXTERNAL ICE SERVICE"              ABSTRACT OF THE DISCLOSURE    Structure for controlling the delivery of ice pieces for external service with the ice pieces being formed within a refrigerator or the like.  The apparatus may include a closure for selectively closing the end of a delivery chute through which the ice pieces are conducted during the delivery operation.  Delivery of the ice pieces is effected by movement of an acutator as by a receptacle, such as a cup or glass, being urged thereagainst to receive the delivered ice.  Movement of the actuator concurrently moves the closure away from the delivery chute and positions a guide in cooperation with the closure to guide the ice pieces from the end of the delivery chute into the receptacle.         The guide may include upstanding side wall portions for pre-venting undesirable lateral discharge of the ice pieces and effectively assuring the delivery of all of the ice pieces into the receptacle.  The guide may comprise a one-piece element removably installed on the actuator for move-ment therewith.  The actuator and guide mounted thereon may be biased to an outwardly directed disposition whereby the guide further serves to direct the last-delivered ice pieces toward the receptacle as it is being removed from engagement with the actuator.  The closure may be biased to close the delivery chute upon completion of the ice piece delivery operation.

Abstract: Inventors: Peter J. Herzl, a citizen of Canada and resident of Morrisville, Pa., and Robert G. Shaffer, a citizen of the United States of America and resident of New Britain, Pa.               ABSTRACT OF DISCLOSURE                  A two-wire transmitter operating in conjunction with a meter whose output signal varies in frequency as a function of the metered variable.  The meter signal is changed into an analog voltage that is converted by the transmitter into a corresponding output current and conveyed to a receiving station over a two-wire line which also supplies operating voltage to the transmitter.  In the transmitter, the analog voltage is applied to a differential amplifier which converts the voltage into an output current via a transistor acting as a variable impedance across the line to make up the dif-ference between the operating current drawn by the transmitter and the output current.  This make-up current is stored to provide an energy source for operating a totalizing counter coupled to the meter to determine the total amount of the variable passing through the meter.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to motion picture special effects generation and control systems and, more particularly, to a system for simulating an effect such as an earthquake.  Prior art special effects systems require ex-tensive modification of the theater in which they are installed, or the theater must be specially built for such system, such as those with a vibrating floor or seat. Additionally, prior special effects control systems require special reproduction equipment which is not compatible with ordinary motion picture projection equipment.  The present invention overcomes the deficiencies of the prior art by pro-viding a special effects system for simulating physical sen-sations in an audience during the presentation of a motion picture in which relatively high intensity, very low frequency random noise is acoustically couple to a theater space to produce psychological and physiological sensations, such as earthquake movements, in the audience.  The special effects are controlled by a control sub-channel which is either frequency multiplexed onto a conventional optical audio track, or, in a magnetic strip film format, the control sub-channel is placed on an accompanying optical track. The presence and amplitude of two control frequencies in the sub-channel are detected and logically combined, providing four separate digital function control signals and two analog control signals which are variable in amplitude.

Abstract: ABSTRACT OF THE DISCLOSURE An elastic joint-spanning waterstop of particular design for use in  a method of sealing joints, in particular expansion joints between con-crete sections in roads, bridge and parking deck structures against passage of water, dirt, etc., is described.  In the method, recesses are formed in the concrete surface of each side of the joint and the specially designed flexible elastic joint-spanning waterstop element is placed therein, and thereafter a layer of rigid-setting grout is then placed over the element. The waterstop element is in the form of a continuous strip having in cross-section a center portion for location in the joint, and lateral joint-span-ning web portions.  The webs have a number of openings therethrough to admit fluid grout therein.  An upstanding rib is placed between the openings and the center section and is spaced therefrom.  The openings in the webs when filled with grout serve to support the upper layer of grout and to prevent flexing and cracking thereof by vehicle traffic passing thereover, as well as to anchor the webs to the concrete bodies.  The upstanding rib is embedded in grout and acts to seal against passage of any water from the joint through the openings when the joint is in an expanded position and the waterstop is stretched.
