Abstract: Abstract of the Disclosure An improved method of making inflatable liferafts and liferafts made by such a method are disclosed.  Hitherto, inflatable liferafts have been made by joining panels of suitable material together by the use of adhesive.  Such a method is labour intensive and the present invention is more economical in the use of labour and takes advantage of modern materials, in that thermo-plastic sheet material which is to form a floor of the liferaft is heat welded around the periphery of the floor to the thermoplastic sheet material which is to form a peripheral inflatable buoyancy tube of the liferaft, after which edges of the material which is to form the tube are joined by heat welding to close the tube along its longitudinal extent.

Abstract: ABSTRACT OF THE DISCLOSURE    In the use of certain metal salts of the hemi-perester of maleic acid as catalysts for the polymerization and curing of ethylenically unsaturated monomers and of methyl methacrylate-containing syrups the addition of an activator such as sodium bisulfite provides a substantial reduction in the curing time.  The process is relatively insensitive to the amount of filler used.  The salts of maleic hemi-peresters, in combination with the activators, are also useful for polymerizing ethylenically unsaturated monomers.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to the field of door latch and lock mechanisms.  Known latch bolt mechanisms and dead bolt mechanisms are individual and separate mechanisms, with the latch bolt mechanisms frequently including its own lock.  Accordingly, two keys (or alternatively, one key fitting both locks) are required to unlock both the latch mechanism and to withdraw the dead bolt.  The present invention provides an improved lock cylinder with dual driver, whereby an independent drive for the dead bolt mechanism and the door latch mechanism may be achieved with a single lock so as to provide withdrawal of both the latch bolt and the dead bolt by rotation of the key inserted into the lock cylinder.  A conventional lost motion drive extends from the rear of the cylinder assembly.  In addition, a cam is coupled to the cylinder assembly threaded cap so as to provide a direct drive thereto, with a cam being coupled to the latch mechanism so that both the dead bolt and the latch bolt are retracted upon rotation of a key in the lock.  Separate drives for the dead bolt and latch bolt allows retraction of the dead bolt faster than the latch bolt, tending to avoid binding of the latch bolt sometimes encountered with other mechanisms.  In a preferred embodiment, the cam is captured and retained with respect to the cylinder assembly.  In a second embodiment, the cam is a slip-fit to the cylinder assembly and retained by additional structure.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for converting a naphtha feedstock to a pure benzene including the steps of:  reforming the naphtha; removing a major fraction of C4 - C5 and heavy reformate components to obtain a reformate containing a major portion of C6 - C8 aromatic hydrocarbons and an associated saturated portion; extracting the aromatic hydrocarbons from the reformate countercurrently in a simplified process with a selective hydrophilic solvent, such as sulfolane, having high solubility for aromatic hydrocarbons and low solubility for paraffin hydrocarbons to obtain an extract stream rich in C6 - C8 aromatic hydrocarbons and a raffinate stream rich in paraffinic hydrocarbon.  and recovering the selective solvent from the extract stream to obtain an aromatic component comprising a major C6 - C8 aromatic hydrocarbons and about 3 to 18 wt. paraffinic hydrocarbon impurity.  The paraffinic impurity is removed and alkyl benzenes are converted by hydrodealkylating the aromatic component to recover substantially pure benzene. A feature of the simplified extraction, process provides for low energy consumption because no stream rich in paraffin is recycled to the solvents extraction unit, thus eliminating the need for stripping the paraf-finic impurity from the aromatic component prior to dealkylation.

Abstract: ABSTRACT OF THE DISCLOSURE      A mirror mounting is described in which a plane rectangular reflecting strip is deformed along the two longer edges thereof so that it is approximately tangent to the ideal mirror while the strip remains substantially flat in the direction of its shorter edges.  In the preferred embodiment of the invention, a plurality of such reflecting strips are so formed by attachment to a support-ing frame using a pair of elastomeric cushion frames to embrace the longer sides of each strip while leaving the shorter sides free.  Advantageously, each reflecting strip on the frame is bent in a continuous manner the full distance of its longer side.           The frame is preferably a rigid array of parallel channel members each of which is adapted to receive a curved T-section angle bar having the desired curvature of the reflecting strip.  The angle bars are deformed into this curvature in a separate opera-tion while they are being attached to the channel members.  Speci-fic apparatus for deforming the reflecting strips into conformity with the curved angle bars and for attaching the strips to the cushion frames is also described.

Abstract: EQUATE OPERAND ADDRESS SPACE CONTROL SYSTEM         ABSTRACT OF THE DISCLOSURE Equate operand spaces (EOS) control over the addressabilities pro-vided by different address keys in an address key register (AKR) in a processor.  When enabled, the EOS control forces each source operand access to occur within the sink operand addressability specified in the AKR, even though the AKR explicitly specifies a different addressability for source operands.  When the EOS feature is disabled, the source operand addressability contained in the AKR is used when fetching source operands.   An EOS field in the AKR stores whether the EOS state is enabled in the processor.  The EOS field is connected to active address key (AAK) select circuits.  When the EOS state is enabled, it outgates from the AKR the sink operand address key as the AAK in response to a source oper-and request.  The source operand address key in the AKR is not disturbed by EOS enablement or disablement.  Upon disabling the EOS state, the AAK select circuits resume any separate addressabilities available in the AKR for the source and sink operands.

Abstract: ABSTRACT OF THE DISCLOSURE         A high security subscription television system which includes the feature of dynamic scrambling and descrambling of cable-connected television signals in response to real-time coded control signals.  The system also has the ability to precisely tune the frequency con-verter unit at the subscriber's site, in response to real time coded control signals provided by a computer at the central transmitting station.  Various methods of scrambling and descrambling are described which use manipulation of the video signals at the baseband video level, and also at the RF level.  Alternate embodiments of the descramblers include a secondary source for the reference carrier signal required for proper descrambler operation.  In an ultra-stable embodiment of a subscriber's control terminal, a single crystal controlled master oscillator is used to control the frequency conversion unit, to provide a clean reference carrier signal for the descrambler unit, and to tune the control signal receiver, thereby removing the need for frequent fine tuning control adjustments, and further allowing simplified system design and fabrication.

Abstract: ABSTRACT OF THE DISCLOSURE             A modified three-phase bridge circuit, incorp-orating resistors and thyristors connected in specific configuration in one leg of each phase circuit and diodes in a second leg, is adapted for connection to the motor rotor.  A speed control signal modulated with a triangular waveform of predetermined frequency, below the instant-aneous rotor frequency, is applied to a plurality of AND circuits acting as pulse width modulators.  Each AND circuit has an output coupled to the gate of one thyristor in each phase circuit.  Changes in speed control signal representative of calls for increasing speed produce sequentially on successive outputs, a train of pulses increasing in pulse width to full turn on.  Additional tyristors are thus gated on in each phase circuit to modify the effective resistance presented by the resistors in each leg so as to smoothly decrease the resistance of the bridge circuit.
