Title: Procedure for assembly of cigarettes
Inventor: BRACKMANN WARREN A
IPC: A24C5/40
Filed: 1990-08-08
Abstract: "Roll-your-own"  cigarette  are  made  in  a conventional roller device from a charge of tobacco and a  paper  wrapper.    The  charge  of  tobacco is pre-proportioned by enclosing it in a tubular wrapper, which has abutting ends to define a radically-extending strip, thereby providing the  charge  of  tobacco  in a  novel cartridge form.  The tobacco cartridge is placed in the rolling  device,  the  strip torn  off  and the  rollers rolled to eject the remainder of the paper wrapper.  The tobacco charge then is ready to receive the cigarette paper in conventional manner.

Title: Hood for a contact drying cylinder
Inventor: SOININEN MAURI
IPC: D21F5/04
Filed: 1990-09-14
Abstract: Abstract The invention relates to a hood (2) closed at both of its ends (15) and on its sides (14), intended for being fitted over the web-drying cylinder surface (1) segment of a contact drying cylinder, usually a so-called Yankee cylinder, in which hood the flow of the drying gas is promoted by means of a partition wall (4) which is substantially parallel to the cylinder sur-face (1), extends across the whole hood (2) and is at a dis-tance from the cylinder surface (1) and the hood mantle (3), in order to form two concentric flow channels having a longi-tudinal cross sectional shape of a circle arc and conjoining substantially at the ends of the hood. The outer flow channel has an inlet (11) for the drying gas, and in its vicinity there is an outlet (12) for the damp drying gas, separated from it by means of a transverse wall (10). According to the invention, when the partition wall (4) is located at such a distance from the cylinder surface that the velocity of the drying gas is high and when it is equipped with heating ele-ments (5) connected to an external source of energy, in order to transfer heat to the drying gas by convection and to the web (W) by radiation, as high a characteristic evaporation is accomplished as is by using high-capacity hoods based on nozzle-blowing.

Abstract: APPARATUS FOR LAUNCHING UMBILICAL-GUIDED MISSILES   ABSTRACT OF THE DISCLOSURE        Guided   missiles  (10)  which  trail  control umbilicals  such  as optical fibers (20) are launched from  an  array  (16) of launch tubes (14) that point in  the  same  direction.    A swing arm (40) extends over  the  face of the array (16) to capture and move the  umbilicals  (20) of previously launched missiles (10)  away  from  the  portion of the array (16) from which  the  next  missile  (10)  will be launched, to avoid  interference between the launched missile (10) and  the  existing  umbilicals (20).  As each missile (10)  is  launched,  the  swing  arm (40) recycles to capture  the  umbilical  (20)  of  the newly launched missile (10).

Title: Railroad hopper car discharge gate valve
Inventor: FRITZ WILLIAM E
IPC: B61D7/00
Filed: 1990-11-14
Abstract: RAILROAD HOPPER CAR DISCHARGE      GATE DISCHARGE VALVE     Abstract of the Disclosure A discharge valve for use in a railroad hopper car discharge gate is in the form of a longitudinally extending shaft positioned between the lips of the discharge gate slope sheets.          The shaft is rotatable about its axis and has axially spaced and axially extending recessed areas.  The recess areas are circumferentially non-aligned, but in part circumferentially overlapping.  The shaft is rotatable between a full open position in which both recessed areas connect the gate interior and the trough beneath the slope sheets; a fully closed position; and two partially open positions in which one or the other of the recessed areas connects the gate interior with the discharge trough.  The improvement of the invention is specific to the circumferential relationship between the recessed areas.  These areas are disposed such that in the fully closed position, the longitudinal edges of each recessed area are substantially circumferentially beyond the spaced lips of the slope sheets such that slight rotation of the shaft in either direction will not result in the opening of either recess area to the interior of the discharge gate.

Title: High performance washing process for vertical axis automatic washer
Inventor: CUR NIHAT O
IPC: D06F33/37
Filed: 1990-12-20
Abstract: A method for laudering a textile wash load is provided for use in a vertical axis washing machine in which a concentrated detergent solution is continuously applied to a spinning wash load for a predetermined time period to thoroughly wet the clothes load. The initial charge of detergent is thoroughly mixed with the detergent in a recirculation step before being applied to the clothes load. The concentrated wash liquid is incrementally applied to the spinning clothes load until a sufficient amount of wash liquid is detected as having been introduced to the wash zone. That amount of wash liquid is then recirculated and reapplied to the clothes load for a predetermined length of time. After the time period, additional water is added to the solution to dilute it to a normal concentration and then mechanical agitation and rinsing steps are conducted to complete the wash cycle.

Abstract: ABSTRACT OF THE DISCLOSURE            A method of increasing the rate of methane pro-duction from a coal seam includes introducing a desired volume of a gas, that causes coal to swell, into the coal seam adjacent a wellbore, maintaining the coal seam adja-cent the wellbore in a pressurized condition for a period of time to permit the gas to contact a desired area of the coal adjacent the wellbore, and relieving the pressure within the coal seam by permitting fluids to flow out from the wellbore at a rate essentially equivalent to the maxi-mum rate permitted by the wellbore and any surface well-bore flow control equipment.  Uneven stress fractures should be created in the coal by this method which will increase the near wellbore permeability of the coal seam.

Abstract: DEVICE COMPRISING A PLURALITY OF RECEPTACLES ARRANGED IN      A SINGLE ROW FOR CONTAINERS FILLED WITH A LIQUID                     ABSTRACT A device for use in an analyzer is described comprising a plurality of receptacles which are arranged in a single row and into which containers of different length and diameter containing a liquid can easily be inserted.          For this purpose, the device is provided with holding elements at different levels along a side for insertable platforms transversing the receptacles and mounting means along the upper edge for an insertable adapter covering the openings of the receptacles.          The holding elements and the mounting means are partly designed as positioning means and/or as latch means.  Within the receptacles platform and the bottom in base of device have a ramp and the exterior wall is provided with a recess at the upper edge.          Furthermore, a carrying means comprising a handle with a cam and a support is arranged at an end face of device.          Due to this design of the device, the openings of the containers are aligned in a predetermined position above the upper edge and, thus, containers having differing rims and/or sealing members can easily be scanned and processed.  Moreover, the carrying means, in connection with a widened base, guarantees failsafe handling of the containers inside and outside the analyzer.
