Title: Adjustable filter cigarette and a method of  manufacture thereof
Inventor: NICHOLS WALTER A
IPC: A24D3/18
Filed: 1983-09-28
Granted: 1986-09-30
Abstract: ABSTRACT                    Fig. 2 A filter cigarette is provided which comprises a tobacco rod which includes a charge of tobacco 1 wrapped in cigarette paper 3, an integral, axially aligned cylindrical filter plug 4, and tipping paper 8.          In one embodiment, the filter plug is divided into first 6 and second 7 segments with the first segment being rotatable with respect to the second segment.          Rotation of the first segment with respect to the second segment, in one embodiment of the invention, serves to vary the air dilution value of the cigarette.          A cigarette having a variable resistance to draw is also provided, and a cigarette which maintains a constant resistance to draw value as the air dilution value is varied.  In yet another embodiment, an encapsulated flavourant is provided which is released responsive to rotation of the first segment with respect to the second segment.    In another embodiment, the tipping paper is air transmissive, and the wrapping is substantially air impermeable and has a plurality of first longitudinally extending, substantially air impermeable depressions spaced about the circumference of the first segment which are registrable with corresponding second, longtiduinally extending, substantially air impermeable depressions spaced about the circumference of the second segment, such that as the first segment is rotated relative to the second segment, the degree of registry of the first and second depressions varies, thereby admitting varying amounts of air to the filter.

Abstract: BREVET D'INVENTION DISPOSITIF ELECTRONIQUE DE MESURE AVEC FILTRAGE PASSE-BAS ACCELERE, EN PARTICULIER POUR LE PESAGE. TESTUT - AEQUITAS. DESCRIPTIF Dans un filtre passe-bas de type (RC), on place en parallèle sur la résistance (R11) une autre résistance (R15) de plus faible valeur, elle-même en série sur un transistor à effet de champ (Q16). Un discriminateur (40, 50, 60) fournit un signal de type-créneau consécutivement à une variation de la composante continue du signal présent en (A). Un circuit monostable réarmable (80) définit un intervalle de temps neutre de durée prédéterminée consécutivement au début du signal-créneau. Après ce temps neutre, un circuit (20) commute le transistor (Q16) en régime conducteur, ce qui donne une faible constante de temps définie par (R15 et C12). La constante de temps est ensuite ramenée progressivement à une forte valeur par reblocage progressif du transistor (Q16). Le filtre s'applique tout particulièrement au pesage de corps sujet à mouvement d'oscillations, ou bien en milieu vibrant. - FIGURE 2

Abstract: ABSTRACT   sputtering process for preparing amorphous semiconduting films having a reduced number of localized states is disclosed.  In particular, hydrogenated films free of polyhydrides may be prepared according to the inventive process.  In one application of the process, a silicon target is bombarded by separate beams of relatively heavy sputtering ions, such as argon ions, effective in sputtering the target and by passivating ions of a substance effective in passivating localized states in amorphous semiconducting films, such as hydrogen ions.  The products of this sputtering are collected on remotely located substrates to form passivated amorphous films.  films produced according to the process may be doped and junction structures formed during deposition by adding ions of a gaseous dopant to the beam of passivating ions.  In a preferred application, amorphous, hydrogenated silicon films contain hydrogen only in the form of silicon monohydride.

Abstract: FOLDING FISHING NET                   ABSTRACT OF THE DISCLOSURE    A folding fishing net having a foldable rim and handle is conveniently and compactly carried folded in a holster at one's hip during stream fishing.  When a fish is caught, the fish net, using only one hand is unfolded quickly when the fish is ready to be netted.  During its quick one handed rotating to unfurl the net-ting and continued quick one handed sequential unfolding around two orthogonal axes, pivotal joints of the folding fish net at four locations are utilized.  After the unfurling of the netting, during the first unfolding from the compacted non use position, a then longitudinally positioned divided handle, pivotally connected by a then horizontally arranged piano style hinge, and a central rim pivot joint on the folded rim, presently located closely opposite the handle, are both pivoted downwardly at the same time, through 180° around a first then horizontally positioned rotational axis.          Thereafter, two rim pivot joints on opposite sides of the foldable rim are pivoted about a horizontal rotational axis perpendicular to the first rotational axis, to enable the rim to be unfolded from its half size up and over through 180° to full circle size, thereby supporting a full circular draping net which is passed under a fish.          The divided handle, when fully open, via its piano style hinge, backs against itself to prevent further rotational movement.  When a fisherman continues to grip the open handle, refolding of the net is prevented, without relying on any locking means.  During this rapid one handed deployment of the folded fish net into a fully opened net, biasing springs are relied upon to snap the rim into its circular configuration.  Also extruded stops prevent further rotational movement of the components of the rim once they reach the then horizontal circular configuration as they are unfolded to support the netting for receiving a fish.  The fish-erman, using his other hand to guide the fishing pole is still successfully managing the hooked fish as the fish is netted.

Abstract: Abstract of the Disclosure Coin Collection Box for Automatic Cashiers and Coin Changers The compartments (3) of a compartment ring (1) rotatable stepwise about its horizontal axis (2) are bounded at the ring end faces by circular-ring walls (6, 7), at the outer ring circumference by a cylindrical annular wall (19) exhibiting at the top an inlet opening (23) leading into re-spectively one compartment (3a), and at the inner ring circum-ference by a conical annular wall (20) exhibiting at the top an outlet opening (24) offset with respect to the inlet opening (23) in a direction of rotation (17) of the ring, this outlet opening leading into a coin return channel (26) and into a coin overflow channel (27).  Upon a rotation of the ring in this direction (17), the last-received coins drop into the coin return channel (26).  Upon a rotation in the opposite direction (18), respectively one coin is received while another coin, exceeding the capacity of the compartment ring (1), drops into the coin overflow channel (27).  The conical shape of the inner annular wall (21) prevents that a coin, dropping through the inlet opening (23) into a compartment (3a) and rebounding, projects temporarily into the inlet opening (23) where it could block the coin collection box during the immediately subsequent rotation of the compartment ring.          Ribs (34) on the compartment walls (4) prevent sticking of a coin to the walls.  By means of ribs (35) at the outlet opening (24), the coins are lifted before they reach this opening, and are thereby detached from the compartment walls (4), if necessary.
