Abstract: MOLDED SEPTIC TANK ABSTRACT OF THE DISCLOSURE          A septic tank is formed from a plurality of tank modules  each of which comprises a substantially closed container.   Each tank module is bolted to a next adjacent tank module at a flat end wall thereof with the bolts being of large diameter and in some cases including a central longitudinally extending opening so that the bolts act to communicate fluid from one tank module to the next.  Each tank module is shaped with an upper wall part which is of parabolic arch shape and a base wall which is substantially flat.  Tanks can thus be formed in modular parts so that various different size modules can be connected together by the above coupling technique to form a multitude of different sizes of tank.  An access opening in the upper wall is defined at the junction between two tank modules with the central dividing walls between the tank modules being cut down to allow a person to enter either of the tank modules  from the  single access opening.  The tank provides a required strength at minimum  wall  thickness  and  also  the  end  walls automatically provides bulkheads for dividing one septic compartment from the next.

Title: Injection site
Inventor: LARKIN MARK E
IPC: A61M39/04
Filed: 1990-07-31
Abstract: ABSTRACT OF THE DISCLOSURE     An injection site for the infusion of a medicament into a flow path for a parenteral fluid and, more particularly, an injection site which is essentially self-priming and air-occluding and which is of extremely simple construction and easily assembled.  Furthermore, the invention is also directed to an injection site of the type described herein which is especially adapted for use as an injection port of a Y-connector utilized for an intravenous administration set.  The device incorporates a self-sealing puncturable member of resilient material, such as rubber, which member is of a substantially spheroid configuration, the tubular segment so as to be in close proximity to the and which is swage-molded into a receiving housing in the tubular segment so as to be in close proximity to the inlet tubing for the flow path of the parenteral fluid.  This, in effect, will largely eliminate the formation of any potential spaces in which air may be entrapped at the injection site while, concurrently, the generally spherical configuration of the puncturable member, particularly the curvilinear surface which is contiguous with the flow path for the parenteral fluid, will cause any minute quantities of introduced air, if at all present, to be conducted out of the inlet for the parenteral fluid so as to essentially render the device self-priming.

IPC: H02P7/00
Filed: 1990-08-01
Abstract: BI-MODAL DC MOTOR CONTROL FOR A MOTOR DRIVEN ANTI-LOCK BRAKE SYSTEM            Abstract of the Disclosure Differential performance characteristics are achieved in a motor-driven anti-lock braking system with a DC motor having a first brush which is employed for both forward and reverse motor rotation, a second brush which is employed in connection with the first brush when forward motor rotation is desired, and a third brush which is employed in connection with the first brush when reverse motor rotation is desired. The second and third brushes are displaced along the circumference of the motor commutator such that the first and second brushes encompass more turns of the rotor winding than the first and third brushes.  As a result, more of the winding turns are active in the forward direction, and the motor torque is maximized for developing the required brake pressure. On the other hand, fewer of the winding turns are active in the reverse direction, and the motor speed is maximized to relatively quickly retract the armature within the valve bore to relieve the brake pressure.

IPC: G11B5/60
Filed: 1990-08-09
Abstract: A disk drive in which the rotatable magnetic memory disks and the metal actuator are electrically isolated from the metallic mainframe of the disk drive and the magnetic heads on the metallic actuator, the coils of the magnetic heads  and  the  magnetic  memory  disks  are  maintained  at electrical potential levels which are sufficiently close to prevent arcing therebetween and which is different from the potential of the main frame.  Electrical isolation is achieved by electrically insulating the disk spindle on which the disks are  journaled  from  the  mainframe  and  by  electrically insulating the metal actuator from the metal actuator support when the metal actuator support is attached directly to the main frame, or by electrically insulating the metal actuator support from the main frame.   An electrical potential is applied to the disks via the disk spindle and to the body of the magnetic heads via the metal actuator arm to provide potential levels which among these parts are sufficiently close to prevent arcing.

Abstract: A main optical waveguide portion and/or branching opti-cal waveguide portions of the optical waveguide is tapered in such a way as it expands towards the output side for reducing a coupling loss due to mismatching of numerical apertures N.A. between optical fibers and the optical waveguide, wherein the light entering the opti-cal waveguide at an angle determined by the numerical aperture N.A. of the optical fiber gradually reduces its angle of incidence to an interface of the core and clad as it passes by a portion where the taper is provided and when the light reaches to the output side of the optical fiber, the numerical aperture N.A. thereof is effectively reduced to a value which is lower than the numerical aperture N.A. determined by a difference of refractive-indices in the optical waveguide, and there-by, by making the numerical aperture N.A. of the optical waveguide little greater than that of the optical fiber, it is possible to reduce the loss at the input side as well as the loss at the output side simultaneously, and further, the taper is not necessarily be a straight taper but a curved taper can be used.

Abstract: (57) Abstract Coupling for measurement of low capacitances (C1,C2,C3). The coupling comprises an oscil-lator, such as an LC or RC oscilllator, whose output frequency (fo) is a function of the capaci-tance to be measured and connected between the input terminal (16) of the oscillator and the ground. The capacitances (C1,C2,C3) to be meas-ured are connected alternatingly to the input terminal (16) of the oscillator. With the excep tion of the capacitance to be connected between the input terminal (16) of the oscillator and the ground for measurement, the other capacitances to be measured are connected, by one of their terminals, to a wire (19) common of the capaci-tances (C1,C2,C3) to be measured and, by the other one of their terminals, to the output of the voltage follower. The input of the voltage fol-lower is connected to the input terminal (16) of the oscillator coupling. The voltage follower consists of an operation amplifier (20), whose output is connected to its inverting input, to which the capacitances (C2,C3) that are not be-ing measured are connected so that there are no voltage differences and, consequently, no charg-ing currents in their terminals.
