Abstract: Abstract of the Disclosure A magnetic storage device comprising a rigid apertured cartridge containing a flexible magnetic disk and a Bernoulli surface is disclosed.  The cartridge contains a reference surface which is integral with the Bernoulli surface and serves to align and flatten the Bernoulli surface when the cartridge is inserted into a disk drive.  The cartridge is configured such that the flexible magnetic disk is maintained in operative association with the Bernoulli surface.  The aperture of the cartridge serves as an entry point for the motor spindle and transducer of the disk drive.  The cartridge is partially enclosed by a slidable shutter which protects the Bernoulli surface and flexible disk when the cartridge is not in use.

Inventor: HOGARTH IAN
IPC: B41J31/05
Filed: 1987-10-09
Granted: 1992-04-21
Abstract: ABSTRACT          An overlappingly overstrikable ink ribbon for matrix or needle printing systems is described having a carrier film 3 and an irk-releasing coating 4, as well as optionally further conventional intermediate coatings.  An rubber-elastic   layer 2 is formed on the needle impression side.  A process for producing this ribbon is also described.  This ribbon has many advantages compared with known ribbons.  It protects the print head, withstands the needle pressure for a longer time due to the elastic layer and improves the printing definition.  It can be produced by coextrusion of the starting materials of the carrier film and the rubber-elastic layer.          (fig. 1)

Abstract: PUMP CONTROL SYSTEM FOR INSTANTLY     REVERSING THE DRIVE MOTOR Abstract of the Disclosure A liquid flow system comprising a bidirectional liquid pump, a bidirectional electric motor coupled to drive the pump, and a liquid flow line having the pump connected therein.  The system further comprises a motor control circuit connected to power the motor in either the forward or the reverse direction.  The control circuit includes a switch for connecting the motor windings to the power lines, the switch being operable to instantly reverse the power connections when the motor is operating in the forward direction and thereby powering the motor-pump to an instant stop and then immediately powering the motor in the reverse direction.  The pump thereby instantly reverses the liquid flow in the flow line and abruptly terminates the flow.  To quickly start the flow again in the forward direction later on, a priming loop is connected to the pressure side of the pump, so that the pump is able quickly to develop pump pressure.

Abstract: VIBRATION TRANSDUCER MOUNTING                 ABSTRACT OF THE DISCLOSURE    A mounting arrangement for vibration transducers such as accelerometer sensors particularly suited for adverse environments as may be encountered with machine tool components and the like. A mounting base is permanently fixed to a vibratory surface to be monitored. This cylindrical base incorporates an annular retaining groove formed in its side surface which cooperates with an annular resilient band which is discontinuous to provide ends which, in turn, may be drawn together when the band is constricted by an external clamp. The band includes a stud ring which engages the groove of the mounting base and then permits facile engagement of a transducer base having a V-shaped groove configured at the lowermost portion thereof. The retainer ring or band also incorporates a detent ring which engages the groove of the transducer base. A hose clamp or the like then is used to constrict the resilient annular band to drive the transducer into a compressive relationship with the top surface of the mounting base. A cable clamp may be employed which serves to retain armor cladding over communications cable emanating from the transducer and is removably retained in position by the hose clamp.

Title: Multi-function port for voltage controlled oscillator
Inventor: BELL ROBERT K
IPC: H03C3/08

Granted: 1992-04-28
Abstract: ABSTRACT     MULTI-FUNCTION PORT FOR VOLTAGE  CONTROLLED OSCILLATOR         A circuit for use in conjection with a voltage controlled oscillator (VCO).  The circuit introduces modulation into a radio system (to create a substantially flat frequency response) at the same VCO port at which VCO frequency centering and negative bias control signals are introduced.  A potentiometer is utilized both for providing an adjustable negative bias to the varactor in the VCO resonant circuit and for setting the VCO to the appropriate center frequency.  Modulation compensation circuitry is coupled to the control arm of the potentiometer and to the anoide of the varactor (via a choke 4).  The modulation compensating circuitry is preferably designed to have a transfer function that is substantially the inverse of the closed loop transfer function of the phase locked loop system with respect to the frequency modulation of the VCO.
