Abstract: TITLE OF THE INVENTION         "MATERIAL WEB FOR THE MANUFACTURE OF FILTER RODS FOR  TOBACCO PRODUCTS AND APPARATUS AND PROCESS FOR PRODUCING SUCH WEB"               ABSTRACT OF THE DISCLOSURE           The invention relates to a longitudinally creped paper web for use in the manufacture of filter rods.  In order to improve the filtering capacity and resistance to flow therethrough without weakening filter plugs formed from the web in respect of resistance to radial crushing the longitudinally creped web is provided with linear indentations transversely thereof which are sufficiently closely spaced one from the other longitudinally of the web to provide consistency in draw of short length sections cut from filter plugs made from the web.  The invention also relates to the process and apparatus for forming such a filter web using co-operating spaced rollers for forming controlled linear compression zones extending transversely of the web, at least one of these two rollers being provided with ribs extending at least approximately axially of the roll.  A drive to the two rollers is synchronised so that the surface speed of both the rollers is at the same speed as the speed of advance of the web being treated thereby.  The treated web may either be formed into a roll or coil for storage and subsequent use or may be fed directly to a tow machine in which it is formed at once into filter plugs in the conventional manner.          The invention also relates to filter plugs of which the filling comprises the gathered together material web.                           - 1a -

Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides an electrophotographic device by which the surface potential of a photosensitive member is substantially uniformalized at the time of termination of the photocopying process by rotating through one revolution the photosensitive member after completion of the copying process and subjecting the photosensitive member to A.C. corona discharge or light exposure.  Moreover, a reflecting mirror and an in-mirror lens are integrally rotated so as to adjust the light path length to obtain the most effective exposure.          Furthermore, the ratio of width of the central portion and of both end portions of the slit for exposure can be varied to obtain a uniform and effective exposure.

Abstract: Applicant:     Pomona Service & Supply Co., Inc.         Title:         Turret Bagger ABSTRACT           An automatic bagging machine includes a bag-pickup station, a bag-filling station and a bag-tying station spaced equidistant from one another circumferentially around an orbit.  A vertical shaft positioned centrally of such stations supports a set of radially extending bag-holding and spreading arms over each of the stations.   Drive mechanism incrementally rotates the central shaft to move each set of arms sequentially from the pickup station to the filling station, then to the tying station and back to the pickup station.  Control mechanism actuates the arms to pick up and spread a bag at the pickup station, grip and maintain the bag open for filling at the filing station, close the filled bag for tying at the tying station, release the filled and tied bag over a discharge conveyor and move the arms into position for picking up another bag at the pickup station.  The drive mechanism also reciprocates a lower arm between the filling and tying stations for steadying each filled bag while it is being moved between such two stations.  Brake mechanism is provided to decelerate the holding and spreading arms as they approach a bagging machine station.

Abstract: IMPROVEMENTS IN SHAVING APPARTUS     ABSTRACT     A razor has a handle holding a pair of double edged blades held in a carriage member by means of a spring yoke with cartridge engaging hooks on each arm of the yoke. Dimple bearings or. each side of the blade cartridge hold the yoke hooks in engagement with the cartridge .          The yoke bears against a lip of the handle end by a push rod integrally formed with the yoke. The push rod moves the yoke forward in the razor handle by means of a tooth and ratchet means on the handle..  A force push on the rod spreads the hooks. to release the cartridge. Loading of the razor with a blade cartr-idge is is effected by pushing the handle onto a cartridge which will spread the hooks over the dimples and the force push on the rod releases the tooth and ratchet in the handle to allow the hooks to spring into gripping position about the cartridge.

Abstract: GAS DIFFUSER, AERATOR, OR SPARGER APPARATUS AND METHOD           ABSTRACT    The field of the invention relates to the disso-lution of gasses such as air or oxygen in aqueous liquid as is commonly done in the treatment of sewage wastes. The problem in the prior art is to effect sufficient dissolution of such gasses to avoid the waste of gasses not dissolved, Also, to effect the dissolution of grater quantities of gas to more quickly treat suspended contaminants. This prior art problem is greatly aided by causing both the gas and the liquid being treated to intersect magnetic flux lines simultane-ously. Momentarily this displaces the hydrogen bonding in aqueous liquids which lower viscosity and facili-tates dissolution of gas at the liquid interface of each gas bubble. This greatly improved dissolution of gas in the gaseous treatment of liquids is effected by gas chamber (4) which releases gas into the liquid in which submerged. The released gas causes circulation of liquid between magnetic chamber walls (12). Here the gas contacts the liquid at the moment of hydrogen bond displacement by the intersecting flux lines of magnetic plates (2).
