Title: Coin wrapping device
Inventor: TRUPPE ROBERT B
IPC: B65B67/08
Filed: 1990-10-26
Granted: 1994-05-24
Abstract: ABSTRACT OF THE DISCLOSURE      A device for wrapping coin rolls includes a base supporting a pad of wrapper sheets for wrapping a roll of coins initially supported by an end wall and two side walls located at one end of the base.  The end wall is spaced a distance less than the diameter of the coin roll from the adjacent edge of the wrapper sheet pad so that the coins rest at the edge of the pad before starting each wrapping procedures.  Strips of contact adhesive on the upper side of the wrapper sheets holds the wrapper to the coins and causes the wrapper sheet to adhere to itself when the wrapping is completed.

Title: Frictional sash balance and jamb liner
Inventor: STARK IVAN L
IPC: E05D15/22
Filed: 1991-02-07
Granted: 1996-01-02
Abstract: A sash balance apparatus for vertically slidable window installations, in which a friction shoe is disposed in a channel formed by a jamb liner extending along each side of the slidable sash and a connecting member extends between the sash and the friction shoe in a manner such that the weight of the sash when applied to the shoe tends to pivot the latter at least slightly within the jamb liner channel and thereby bring predetermined surfaces of the shoe into frictional contact with corresponding surfaces of the jamb liner channel, preferably including elongated rib-like intermediate walls which extend into the channel from its sides.  The channel thus provides a plurality of different longitudinally-extending friction surfaces which may be selectably engaged by the friction shoe as a function of its particular configuration, dimensions, and the degree of tilt introduced by the applied weight of the sash.  In a preferred form, the connector extending between the sash and the shoe comprises a rigid member disposed at an acute angle with respect to the shoe and its channel to promote tilting, and in the most preferred form the connector comprises a particularly bent section of metal wire or rod which is press-fitted or otherwise frictionally attached to the shoe.          Also, the jamb liner has laterally offset tab portions which provide integral stops for limiting allowable vertical travel of the shoe.

Abstract: An  optical  system having  a  substantially  flat  image field is disclosed.  The optical  system is formed from optical  subsystems wherein  an  input  optical  subsystem forms an intermediate image which is the object of an output  optical  system.   The  intermediate  image  has  a curvature  which  compensates  that  from  the  remaining optical  components  of  the  system  to  result  in  a substantially  flat  image  for  the  optical  system.

IPC: G11B5/86
Filed: 1992-02-17
Granted: 1999-03-30
Abstract: The present invention falls within the technical field of devices for the duplication of industrial magnetic tapes.          More particularly it relates to an electronic device for the fast duplication of magnetic tapes.  The device, through a microprocessor, activates selecting circuits to control static memory cards of a memory bank.  The selecting circuit generates proceeding signals and selecting signals which single out memory cells of the memory bank for writing and reading.  These selecting signals and proceeding signals cause a subdivision of the cards in the memory bank, allotting a part of the memory for reading and another part for writing.  The selecting and the proceeding signals are carried out through digital signals.  The final digital signals are subjected to a digital-to-analog conversion.

The ring has two lower edges having a downwardly directed concavity defined between them such that a first of the edges abuts the sheet so that an upper surface of the ring may be pressed downwardly by a fastener to press the edge against the sheet to localize compressive forces between the edge, sheet and skirt to seal against entry of water between the sheet and skirt.  The device disclosed is a pipe sleeve of spun aluminum.  There is a circular base ring adhesively fastened to the underside of the skirt and the clamping ring is circular and of flexible aluminum, with a crescent-shaped cross-section.  The arrangement is such that the circumferential edges of the clamping ring are coextensive with the circular base ring.  Typically the elements of the device have communicating apertures for insertion of bolts upwardly therethrough and nuts are screwed onto the bolts for fastening of the elements together.

Granted: 1997-09-02
Abstract: A circuit and method for variably adjusting a data detecting level by using a pulse with modulation (PWM) signal. The pulse width modulation (PWM) signal having duty corresponding to a predetermined level control value is generated, and the level of the pulse width modulation (PWM) signal is detected to determine the data detecting level to a level corresponding to the detected level. A read test is performed while the level control value is incremented by a given stage from an initial level control value in in response to a test mode, to determine the level control value less than that generating a data error by one stage to a maximum value. Further, the read test is implemented while the level control value is decremented by a given stage from the initial level control value, to determine the level control value greater than that generating the data errorby one stage to a minimum value. Thus the initial level control value or level control value is obtained by an average value of the maximum and minimum level values. Therefore, the data detecting level adapted for each disk driving apparatus can be adjusted without modifying hardware of each disk driving apparatus, and the data error can be prevented by adaptively adjusting the data detecting level to operating circumstances.

Abstract: A device (10) for treating obstructions in vessels or small openings in the body, comprising a rotatable ablator tip (16) which is guided to the obstruction in a reduced diameter configuration, expanded and rotated to remove the obstruction, and contracted to remove the device from the body. The variably expandable abrasive tip coil (16) in one embodiment is actuated by piston means within the coil. A pair (28, 50) of collars is attached to the ends of the coil (20), and the piston effects relative longitudinal axial movement of the collars and the respective ends of the coil tip. When the ends of the coil tip are so moved, expansion and contraction of the diameter of the coil tip results. In another embodiment, the expansion tip coil is actuated by an expandable and contractible bellows disposed within the coil. In another embodiment, the expansion and contraction of the coil tip are effected by longitudinal axis movement of an internal coil attached to one end of the coil tip, within an outer coil attached to its other end.

Abstract: The invention relates to a process for the production of grain oriented magnetic steel sheets having a finished strip thickness in the range of 0.1 mm to 0.5 mm from slabs having a particular alloy composition. The invention is characterized in that in addition to manganese and copper the slabs have an increased sulphur content and a reduced aluminium content; prior to hot rolling the slabs are heated to a reduced temperature and maintained for a sufficiently long period at such temperature, which is lower than the solution temperature of the manganese sulphides and higher than the solution temperature of the copper sulphides; the slabs are then if necessary first hot roughed and then finish rolled with a reduced final rolling temperature, to the final thickness of the hot strip, whereafter hot strip annealing is performed. The sheets of the present invention have improved remagnetization losses for the same magnetic induction.
