Abstract: ABSTRACT HERMAPHRODITIC OPTICAL FIBRE OR ELECTRICAL CONNECTOR   A hermaphroditic optical fibre (or electrical) connector member including a body 12 with a stepped end surface, and a coupling ring 14 slidable over the body and rotatable about the longitudinal axis 18.  The body has a rearward cylindrical portion 26 and a forward semi-cylindrical portion 28.  Two diametrically-opposed lugs 40 extend inwardly on the coupling ring and two circumferential grooves 44, 46 are provided on the forward portion 28 of the body 12.  In one rotary position of the coupling member it can slide longitudinally rearwardly to allow the transverse end surface portions 20, 22 to be wiped clean.  The coupling member is then aligned with an opposed identical coupling member and initial guiding location is provided by a pin 32 and groove 34 on each member.  The coupling rings are then slid together and each rotated 90° such that the two lugs 40 on one coupling member engage with the rearward groove 46 on that connector member and with the forward groove 44 on the other connector member. The connector member is relatively simple to make and provides accurate positioning of the fibre terminations 30.

Abstract: IMPROVED TELEPHONE                ABSTRACT OF THE DISCLOSURE         A telephone handset having a receiver and a transmitter and line seizure capability by a manually actuatable on-off switch.  Line release is either through this switch or through an automatic line release switch.          The on-off switch translates to an "on" position from an "off" position, and in this translation applies a force to a link through a spring that tends to rotate the link.  A step of the switch prevents rotation by bearing against a pawl of the link until a notch registers with the pawl, whereupon the link rotates to an "on" position.  When the lever rotates, a crank of the link pulls on the automatic line release switch to cock it.  The automatic line release switch engages a finger on a cradle when the handset is placed on the cradle, and when engaged the release switch rotates the lever and the on-off switch to its "off" posi-tion, opening blade contacts to release the line.  The on-off switch may be switched to "off" manually independently of the automatic line release switch and when this is done, the pawl rides out of the notch to rotate the link and retract the automatic line release switch.  The lever, on-off switch, and automatic line release switch are dynami-cally balanced to avoid inertial actuation.  The handset includes a housing formed of an upper shell, a lower shell, and two grip pieces.  The lower shell has a well that receives a key pad circuit board switching network, a key pad, and an escutcheon in stacked fashion, with the escutcheon secured to the lower shell and clamping the lower shell and grips to the upper shell by threaded faste-ners.  The upper shell and the lower shell are similarly clamped together at one end of the wall by fasteners.

Abstract: ABSTRACT OF THE DISCLOSURE           This specification discloses assay systems which detect the presence of, or measure or monitor the extent of, an enzyme-catalysed reaction on a substrate.  The systems of the present invention can be used to detect or measure the enzyme or the substrate, depending upon circumstances.  The specification further discloses a method of assay of the type in which an electrode poised at a suitable potential is contacted with a system comprising a first enzyme, a substrate which undergoes a reaction catalysed by the said enzyme, and a mediator compound which transfers charge to the electrode from the first enzyme when it is catalytically active, whereby the current flowing in the electrode is a measure of the reaction taking place; in which at least one further enzyme and associated compound is incorporated into the system, the further enzyme being productive of, or also being reactive with, the substrate so as to affect its presence or level, but not being electrochemically linked by the mediator to the electrode, whereby the consequent difference in electrode current flowing with, and in the absence of, the second enzyme and its associated compound is a measure of the extent of reaction of the further enzyme with its associated compound and thus permits the amount of one to be established if the amount of the other is known.

Abstract: ABSTRACT           Digital processing of speech signals for compression/ expansion pitch change is provided by writing and reading a ROM at different rates and controlling the discard/repeat segments of memory to be integral multiples of the pitch period.  The write address and memory samples the audio signal and records digital samples in sequence.  The read address follows this sequence at a controlled rate either faster or slower than the writing rate to obtain expansion or compression of the speech signal.          Thus the read address will approach or recede from the write address depending on whether its clock rate is greater or less than the writing rate necessitating a jump in address position.          It is the decision of when to make this jump that is controlled by the logic to prevent the read pointer from overtaking the write pointer or falling too far behind it.  The jump in the read address location is always in a direction such that it does not cross the writing address.

Abstract: ABSTRACT         This invention relates to a scheme for generating electricity using gravitational energy.  The scheme uses a set of massive underground spinning wheels, each wheel being fitted with a mechanism to receive and transmit gravitational torque pulses from a passing vehicle to keep the wheels in motion.  The mechanism used to apply the torque pulses to the spinning wheels consists of a stepping board, a hollow cylindrical rod disposed vertically and a shoe attached to the lower end of the vertical rod by a hinge with the upper end of the rod protruding above the ground surface   A steel linkage connecting the stepping board and the lower part of the shoe is used for initial positioning of the shoe.  Both the stepping board and the protruding end of the vertical rod are kept in their initial upward positions by means of two springs.  The electricity is generated by using   each spinning wheel in combination with an appropriate gear system to act as the prime mover of an alternator.
