Title: Apparatus for testing the burst strength of a line of  perforations
Inventor: WALTER ALFRED
IPC: G01N3/08
Filed: 1978-01-10
Granted: 1980-11-04
Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus for testing the burst strength of a line of perforations in a sheet of paper.  The testing apparatus comprises a first means fixedly mounted in a frame for gripping a sheet of paper on one side of a line of perforations extending across the paper and a second means rotatably mounted in the frame in spaced relation to the first means for gripping the paper on the other side of the line of perforations.  A pendulum is attached to the second means so that swinging of the pendulum causes rotation of the second means.  The pendulum may be swung along a path which extends from a first position, where energy is stored in the pen-dulum, through a second position, where the paper is rendered taut and the line of perforations is burst by the energy stored in the pendulum, to a third position, where the energy remaining in the pendulum after the bursting action is dissipated.  An indicating means is provided which is actuated by the pendulum for indicating the amount of energy remaining in the pendulum after the bursting action.  An apparatus is also provided for providing various dif-ferent lines of perforations in a paper sample for use in the testing apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is an apparatus for separating from ruminant animal feces the undigested fibrous material that is preponderantly short pieces which consist of bundles of capillary tubes. The apparatus includes a supply tank to receive a slurry that contains ruminant animal feces and added liquids including urine, means in the supply tank for agitating the slurry to make it substantially homogeneous and a first stage separator to separate the slurry into a filtrate consisting preponderantly of liquid and fine solids, and a filter mass consisting preponderantly of the short pieces of fibrous material.  The separator includes a first stage hopper which is airtight and has an inlet near its lower end to receive pumped slurry, whereby there is a gas pressure in excess of atmospheric on slurry entering the first stage separator.  The apparatus also has a foraminous separator drum which is rotatable on a horizontal axis at the bottom of the hopper with a squeeze roller surmounting the separator drum slightly downstream of the vertical diameter of the drum. Means urge the squeeze roller against the separator drum with heavy pressure to compress the capillary tubes and express the majority of the liquid therefrom. A filtrate discharge is provided for the separator drum and a filter mass scraper blade bears on the separator drum downstream from the squeeze roller.  Means are provided for pumping the slurry from the tank into the hopper and means are provided for rotating the separator drum to force the filter mass forwardly beneath the roller and onto the scraper.

Abstract: ABSTRACT OF THE DISCLOSURE   A modular utility unit is provided which is intended to replace a door on a van-type wheeled vehicle.  The modular utility unit includes: a utility-containing and appliance-containing unit having a facade, a base, a top, sides and an exterior surrogate door panel; utility appliances disposed within the modular utility unit; and clamps disposed within the modular utility unit in proximity to the surrogate door panel. When the door of the vehicle is removed, the clamps cooperate with a door frame of the vehicle for securing the utility unit within the vehicle.  Releasing the clamps enables removal of the utility unit from the vehicle, and the door of the vehicle may then be replaced.  Thus a van-type vehicle can be converted to a utility unit containing camper van merely by replacing one door thereof with the above described modular utility unit.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention is directed to a cutterhead for a portable power planer. The cutterhead includes a cylindrical body having a substantially cylindrical surface and defining a rotational axis about which the cylindrical body rotates during normal operation of the power planer.  A solid elongated cutting member is provid-ed and has a channel formed therein to define at least two cutting edges.  The cylindrical body has an elongated recess formed therein for holding the cutting member.  The recess extends in a direction parallel to the rotational axis of the cutterhead and defines a longitudinal aperture in the surface for accommodating one of the cutting edges.  The recess has a recess wall extending inwardly away from the aperture to surround and hold the cutting member against the centrifugal forces acting thereupon during the rotation of the cylindrical body.  Positioning pins arranged in the cylindrical body engage the cutting bar to angularly fix the cutting member so that the one cutting edge penetrates the aper-ture at a predetermined angle of elevation with respect to the surface of the cylindrical body. A screw mounted in the cylindri-cal body directly engages the cutting member to tightly seat the latter against the recess wall.

Abstract: 1                PHB.32633 ABSTRACT:           In an acoustic wave device having a pair of spaced apart reflectors forming a resonant cavity, each reflector consists of an array of parallel reflective elements.  At least one of the reflectors is weighted not by simple withdrawal of reflecting elements from a nominal uniform array hut instead by substituting reflec-tive elements of the uniform array with elements provid-ing both net-zero reflection at required positions and also at least partial compensation for the velocity per-turbation which would be produced by such simple with-drawal.  Such weighting may be used to suppress the side lobes of the reflector response and hence improve the stopband performance of the acoustic wave device and, for example, a coupled resonator filter in which that device is incorporated.

Abstract: A B S T R A C T    In a method of providing safe control, storage and transportation of banknotes there is used a closeable cassette (1) provided with locking means, said cassette containing a liquid-dye container (9) which is activated when an attempt is made to force the cassette, thereby to render the banknotes unusable. To prevent a successful robbery against, for example, a store or like place in which banknotes are intro-duced into the cassette with the aid of a special infeed unit (19, 20), the cassette is constructed so that it can be removably connected to said infeed unit while exposing an infeed opening (16), said infeed unit suitably being provided with a counter means. In conjunction therewith, the associated infeed and packing means of the cassette are inserted into the unit, whereupon banknotes can be fed into the cassette. The cassette, with the banknotes therein, is then released from the infeed unit while closing the infeed opening, whereafter the cassette is transported to a collecting location, e.g. a bank, where an authorized person equipped with a key or a code for the cassette lock (lc) empties the cassette of its contents.    The safety function of the cassette includes an electric circuit arranged, when an attempt is made to force the cassette, to ignite a detonator (8) which ruptures the liquid-dye container. The electric safety function is primed automatically when the cassette is closed as it is removed from the infeed unit.    The invention also relates to a safety cassette (1) and an infeed unit (19, 20) for carrying out the method.    (Figs. 2 and 3)
