Title: Electromagnetic pump
Inventor: ORAVA JOHN
IPC: F04B17/04
Filed: 1989-11-20
Abstract: ABSTRACT OF THE DISCLOSURE   Generally there is provided a nonmagnetic sleeve having a check valve at its inlet and housing a piston composed of material responsive to a magnetic flux. This piston contains a through bore and a check valve in the bore to cooperate with an inlet valve to cause a pumping effect when the piston is reciprocated within the sleeve. Movement of the piston is caused by inducing an electrical current in a winding surrounding the sleeve and thereby causing a magnetic flux to act on the piston. Additional pumping power is obtained by affixing a core in a portion of the winding at the inlet to enhance the magnetically induced forces on the piston. In yet a further feature magnetic outer casings are provided surrounding the coil and projecting from the piston to make further use of the outer magnetic flux lines. In both embodiments, return of the piston is accomplished by use of either a return spring or another electromagnetic coil.

Title: Dual firing system for a perforating gun
Inventor: RICLES THOMAS D
IPC: F42D1/04
Filed: 1989-11-23
Abstract: DUAL FIRING SYSTEM FOR A PERFORATING GUN     ABSTRACT OF THE DISCLOSURE     A unitary dual firing assembly includes a high explosive detonation cord with ends, each actuable by a different firing mechanism.  The ends of the high explosive detonation cord are adjacent respective bulkhead membranes which, if broken, are effective to transfer a shockwave to detonate the high explosive cord.  An intermediate section of the high explosive cord is effective to detonate perforating gun apparatus. A hydraulic firing head is located adjacent the membrane at one end of the high explosive detonating cord, while a mild explosive detonating cord is located adjacent the membrane at the other end of the high explosive detonating cord.  An upper end of the mild explosive detonating cord terminates in a stem cap assembly which is responsive to an impact for detonating the high explosive cord, via a lower end of the mild explosive detonating cord.  Mechanical or fluid inputs can thus be applied to reliably detonate one or the other of the firing mechanisms to trigger the perforating gun.

Title: Data transferring system comprising an input-output channel unit capable of predicting an overrun in a data processing device
Inventor: OYADOMARI HAJIME
IPC: G06F13/38
Filed: 1990-02-07
Abstract: On transferring transfer data between a peripheral controller (11) and an input-output channel unit (12), an overrun predicting circuit (45) of the input-output channel unit predicts occurrence of an overrun with reference to an amount of transfer data memorized in a buffer memory (39) and produces an overrun prediction signal (46).  The overrun prediction signal is delivered to the peripheral controller by the use of a start informing acknowledgement signal line (15) which is used in transferring a start informing acknowledgement signal from the input-output channel unit to the peripheral controller before the transfer data is transferred between the peripheral controller and the input-output channel unit.  Responsive to the overrun prediction signal, a strobe inhibiting circuit (21) of the peripheral controller inhibits delivery of a strobe pulse signal from the peripheral controller to the input-output channel unit during a predetermined time interval.

Title: Currency paper, especially bank note, with a safety design and process for producing it

Abstract: DE LA RUE GIORI S.A.             LAUSANNE / SWITZERLAND   ABSTRACT            Currency paper, especially bank note, with a  safety design and process for producing it The safety design printed on a currency paper is composed,  on  the  one  hand,  of  a  basic  design with parallel  lines  (10,  20,  30)  extending in a specific direction, with a plurality of interruptions, by means of which regions in the form of letters are marked out, and of a plurality of line segments (1, 11, 21) which fill these regions. A plurality of groups (R to Z) of letters located next to one another respectively form a word. Within each group, all the line segments are parallel to one another, but from word to word the directions of the respective line segments differ from one another, so that there is a plurality of words with line segments inclined differently in relation to the direction of the basic-design lines. Mutually adjacent successive lines of the basic  design  and  mutually  adjacent  successive  line segments have alternately different colors, preferably three different colors being represented. In an attempt to reproduce a currency paper with a multi-color safety design of this type by means of a color copier, the line segments crossing the sensing direction at a relatively large angle, above all approximately at a right angle, are reproduced more broadly and more diffusely than the line segments and lines extending approximately in the sensing direction, so that, as a result of this line spread, the corresponding words,  inconspicuous in the safety design of the genuine currency paper at a fleeting glance become clearly visible.

Abstract: The manufacture of sag-resistant, lightweight structural mineral panels on a foraminous support wire is accomplished by forming a dilute aqueous dispersion of mineral fiber and/or aggregate and an anionically stabilized latex binder, coupling the binder solids onto the mineral fiber materials by adding a small amount of a flocculant such as a cationic polyacrylamide, and passing the slurry onto a first flooded section of the support wire to form an open, entangled, structural mass having water in interstitial spaces of the entangled  mass.  Water is stripped from the mass and the mass dried without collapse of the open structure by passing heated dry air through the open entangled structure.

Title: Adjustable shaft for an implement and method of using the same
Inventor: AQUILINA PAUL
IPC: B25G1/04
Filed: 1990-07-30
Abstract: An adjustable shaft for an implement which can be increased or decreased in length and can be oriented in a number of ways which change the alignment of the handle end of the implement relative to the operating end of the implement is disclosed.  The adjustable shaft comprises a first shaft and a second shaft of lesser diameter.  The first shaft is hollow and the second shaft is slidably receivable therein.  A mechanism for aligning the second shaft relative to the first shaft is attached to one end of the first shaft.  The aligning mechanism includes a plurality of projections which extend away from the first shaft when the alignment mechanism is connected thereon.          The projections are adapted to engage the second shaft.  A collar member, which is slidable along the second shaft, engages with the projections of the alignment mechanism and presses them against the second shaft so that they frictionally engage the same.  The length of the shaft may be adjusted by simply altering the length of the second shaft which is received inside the first shaft.  The second shaft and the alignment mechanism are configured to interlock with each other so that rotational movement of the second shaft with respect to the first shaft is substantially prevented.

IPC: A63C11/00
Filed: 1990-12-14
Abstract: A modular ski hanger system and kit for mounting the same, is provided with a bracket member which may be mounted on a vertical surface.  Ski hanger modules, which may be slidably mounted on the bracket member, each have an upright thickened back portion and a pair of substantially parallel upright wall members forwardly projecting from the back portion. The wall members are spaced apart by enough distance to permit insertion of a pair of typical skis arranged base-to-base at a portion adjacent their curved front ends, and the wall members have a dimension parallel to the back portion which is great enough to ensure that the pair of typical skis received between them will be maintained together by the wall members without slipping down.  This allows two ski hangers to be positioned with one inverted with respect to the other, allowing close spacing of the skis.  A cylindrical plug member may be inserted through opposed apertures in the wall members of a module in order to provide abutment means to retain the pair skis in the module against forward lateral sliding.  Apertures of adjacent inverted modules are substantially aligned so that locking means may be threaded along the length of a series of modules to lock all skis in place, or alternatively, a single locking means may be inserted through a lateral aperture in the plug member to prevent removal of the plug member from the module.
