Title: Apparatus for the production and packaging of cigarettes
Inventor: FOCKE HEINZ
IPC: A24C5/35
Filed: 1988-12-07
Granted: 1992-06-02
Abstract: Abstract: (In conjunction with Figure 1) 1.  Apparatus for the production and packaging of cigarettes.        2.1  In the production and packaging of cigarettes, the capacity of, where appropriate, several cigarette-producing machines (10, 11, 12) have to be coordinated with the productive capacity of, where appropriate, several packaging machines (13, 14).  The cigarettes (15) are conveyed directly from the cigarette-producing machines to the packaging machines by means of cigarette conveyors.  A cigarette store (16) for compen-sating differences in output is located in the region of the conveying zone.  The known cigarette stores are designed on the principle of a blind-end store.  The new cigarette store is intended to make it possible to achieve closer matching to the productive capacity of the coupled machines by avoiding the use of a blind-end store.        2.2  The new cigarette store (16) is designed as a continuous-flow store in the form of a circular ring, to which the cigarettes delivered by the cigarette-producing machines (10, 11, 12) are fed at various locations, particularly in the region of entry stations (37, 38, 39), and from which cigarettes are extracted in the region of extraction stations (40, 41) for further conveyance to the packaging machines (13, 14).  In the region of the closed cigarette store (16) in the form of a circular ring, a storage stream (43) is conveyed con-stantly in one direction and thus fed to the extraction station (40, 41).        2.3  The cigarette store (16) allows close matching to differences in output both in the feeding and in the extraction of the cigarettes.  Furthermore, a careful treatment of the cigarettes is ensured by avoiding the effect of a blind-end store.

Abstract: ABSTRACT          A cylindrical shaped stent to prevent arterial acute closure and subsequent restenosis formed of longitudinal wires of biocompatible metal.  The wires are welded together in pairs at alternate ends with each pair of wires bent into a V-section.          The wires are all formed into a cylinder welded closed to form the stent.  The stent is compressed and loaded into an outer catheter by a special tool.  The stent is positioned and released for self expansion in situ by an inner catheter.  A guide wire through both assists in threading the catheters through blood vessels.

Abstract: ABSTRACT    A plastic blower including a clam shell housing.  The clam shell members of the housing are sealed together by means of a groove in the edge of one of the clam shell members and a tongue formed on the edge of the other clam shell member.  A strip of flexible sealing material is disposed in the groove and is compressed therein by engagement with the protruding tongue.  The space between the tongue and the walls of the groove converges toward the open end of the groove, whereby an increase or decrease of pressure within the housing relative to the ambient pressure causes the sealing strip to be further wedged into the space, thereby increasing the effectiveness of the seal.

Granted: 1993-05-25
Abstract: PATENT 39-0100.2134 ABSTRACT OF THE DISCLOSURE           In driving a stepping motor which, for example, is used to effect tracking movements of a head in an electronic still camera or other magnetic disk recording and/or reproducing apparatus, and which has a rotor and a plurality of phases to which input pulses are applied in predetermined sequences for establishing excitation states by which the rotor is stepped to respective positions, the input pulses are controlled for alternating between first and second excitation states corresponding to adjacent stepped positions between which it is desired to bring the rotor to rest.  Such alternation is initially effected at a relatively low frequency so that the rotor oscillates between the stepped positions corresponding to the first and second excitation states, respectively, and then the frequency of alternation between the first and second excitation states is gradually increased to a value at which the rotor no longer oscillates with such alternation and comes to rest at a position between the stepped positions.          A duty ratio is selected for the first and second excitation states which inversely corresponds to the ratio of the distances from the desired position of rest of the rotor to the stepped positions of the latter corresponding to the first and second excitation states, respectively, and such duty ratio is applied to the alternation between the first and second excitation states at least during the increasing of the frequency of alternation to the value at which the rotor no longer oscillates.

Abstract: GASEOUS FUEL INJECTION SYSTEM             FOR INTERNAL COMBUSTION ENGINES                           ABSTRACT           A gaseous fuel injection system for internal com-bustion engines features a "variable-pressure-controller" which translates a varying negative pressure, sensed in the engine's air intake system by means responsive to the rate of flow of the  intake air,  into a proportionately varying amount of gaseous  fuel at a positive pressure.   That fuel  is then injected into the engine's air intake system upstream or down-stream Or the throttle valve through flow restrictor means which cooperate with the variable-pressure-controller to pro-vide an amount of fuel proportionate to the rate of air flow through the engine's air intake system.   The invention is entirely mechanical-pneumatic in operation and readily adapted to a wide variety of liquid fueled engines, carburated as well as fuel injected, or to one for gaseous fuel only.

Abstract: Silicic acid modulates (i.e. enhances or inhibits) adenylate cyclase activity.  This effect appears to be a general one, inasmuch as the modulation has occurred in all tissues studied.  The results suggest that silicic acid can be used in human and veterinary medicine to modulate hormone or neurotransmitter response.  The results also indicate that silicic acid can be used to prevent, treat, or delay the onset of calcium-related bone disease, or to improve bone strength in an vertebrate having a bone strength less than desired.

Abstract: During a method for fractional condensation of acid combustion gas components in condensers, by the addition of a peroxide solution to a suitable quantity of excess air, it is possible to avoid the disadvantages of the previously known methods. Exploitation of the latent heat energy of the combustion gasses is thus possible as the purification products become economical through a price reduction of the waste gas purification, resulting also in a reduced strain on the environment and the atmosphere. It should be possible to utilize the combustion gas after purification. In order to attain these ends a dispersed, surface-increasing filter aid suspended in the peroxide solution at a temperature of approx. 220  DEG C is added before the combustion gas enters the condenser, with the subsequent reduction of temperature in the condenser by the oxidized combustion gas to the temperature interval of 160  DEG C-140  DEG C, draining H2SO4, and to the temperature interval of 120  DEG C-110  DEG C, draining HNO3, and further to approx. 20  DEG C where other residual products condense.
