Patent CA-1188424-A (CA)
Inventor: AMIR GIDEON
IPC: H03H21/00

Abstract: ABSTRACT OF THE DISCLOSURE      In one embodiment of this invention, a uniquely designed switched capacitor multiplier/adder (129) is provided which also functions as a digital-to-analog converter in a single subcircuit.  The multiplier/adder, in a single operation, multiplies an analog voltage by a binery coefficient, and sums this product with a second analog voltage.  The use of this unique subcircuit significantly reduces the space requirements for the construction of, for example, a speech synthesis circuit utilizing linear predictive coding over prior art circuits.  This provides a novel structure and method which minimizes error components in the synthesized speech signal due to voltage errors inherent in the use of analog sample and hold circuits which are used to store the forward and backward prediction errors utilized in the linear predictive coding technique.  Using the method of this invention, the inherent error components are alternatively inverted and not inverted upon each clock cycle of the multiplier/adder.  Thus imposing a frequency of one-half the clock rate upon the error components.  These error components are then removed using a notch filter which removes signals having a fre-quency of one-half the clock rate.

Abstract: ABSTRACT      A flange protector (P) is adapted for attachment to a machined surface (S) of a flange (F) of the type having an annular ridge (20) and a plurality of bolt holes (14), which bolt holes (14) extend from surface (S) through the flange.  A cover (10) of flexible material has one side (10s) shaped substantially conforming to the shape of the machined surface (S) and extends over the bolt holes (14) to engage and protect the machined surface (S).  A plurality of fastening means (M) extend from the engaging side (10s) of the cover (10) for frictionally engaging the interior surface (14i) of bolt holes (14) to retain the engaging side (10s) in engagement with surface (S).  Each fastening means (M) includes an elongated tubular shank (12) extending from the cover (10) to an open end (12e). Each tubular shank (12) is hollow, having an inner bore (12b) substantially from the cover (10) to the open end (12e).  The length of tubular shank (12) is shorter than the length of the bolt holes (14) which extend through the flange to avoid inadvertent unseating of the protector.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved process for the manufacture of synthetic lubricant additives from internal olefins is described.  The process utilizes boron trifluoride catalysis with a promoter to produce oligomer mixtures that have surprisingly low viscosities at low temperatures and surprisingly high viscosity indexes as compared with the oligomers found in other methods.          It is important that  internal olefins be used almost exclusively in the method of this invention.

Abstract: ABSTRACT OF THE DISCLOSURE          A compact ramp construction includes a series of nestable, telescopically extendable modules which are connected via an intermediate module to a base that de-tachably anchors one end of the ramp to a loading surface and which storably supports the ramp when the modules are nested.  In one embodiment, the intermediate module is slidably connected to a pair of inclined slots on the base which raises the intermediate module to clear an edge of the loading surface as the nested modules are telescopically extended and lowered to another surface.  Each one of the nestable modules has a pair of parallel side members that are spaced apart by an attached overlapping cross member.          A single lug attached to the free end of each side member slidably engages an uppermost surface of a corresponding side member in an adjacent module and cooperates with the cross member of that module to support a load.  In another embodiment, the intermediate module is hingedly connected to the base such that when the modules are nested, the ramp is stored by being pivoted about its hinges to lie folded against the base.          Instead of a lug at the free end of each side member, the free ends of a second cross member in each module partly overlie corres-ponding side members of an adjacent module and cooperate with the first cross member thereof to support the load.  All of the cross members provide a series of steps in a plane between loading and unloading surfaces.

One or more concentric casing strings are then run through the outer casing hanger at the surface and the suspended casing hanger within the borehole.  The additional casing hangers for the one or more concentric casing strings are run through the outer casing hanger and nested within the suspended casing hanger.  The suspended casing hanger thus provides support for all of the smaller diameter casing hangers and their associated casing strings.
