Abstract: Abstract of the Disclosure Upper and lower molded polymeric housing portions are coupled together to form a closed housing.  Each housing portion has an end wall, the end wall of one having openings for a power receptacle and the end wall of the other having either knock outs to form openings for a power receptacle or knock-outs to form openings for communication connectors.  A hook and groove arrangement permits the housing portions to be coupled together and moved between open and closed positions.  The housing is especially useful-with flat cable in an under-carpet wiring system.

Abstract: MASKED DATA FETCH AND MODIFYING DEVICE            Abstract of the Disclosure A data reading and modifying device of a computer system has a main storage for storing first data, portions of which are to be modified by various modifying data.  The access speed of the main storage is slower than the speed at which the modifying data is accessed.  A controller initiates fetches of first data from the main store and selects the modifying data.  A register is coupled to the main storage for receiving and storing first data as it is provided from the main storage.  Portions of the register are reserved for modifying data which is preferably inserted into the register before receipt of the first data as controlled by the controller.  The first data received from the main storage is inserted into remaining portions of the register and insertion of, first data into portions reserved for modifying data is inhibited, such that modified data is available without a write back to the main storage location of the data to be modified.

Abstract: ABSTRACT  OF THE DISCLOSURE            PIPELINE OR CABLE PLOUGH            The plough consists of two portions separable by rams (72).  Each portion comprises a beam (14, 16) joined to a plough body part (18, 20).  The portions include two pairs of longitudinally-spaced arms (69) interconnected by pivots (70).  At each and of the plough a support including bearers (61) is closed by a ram (59) to entrap the pipeline (26).  Another ram lifts the support to raise the pipeline between the plough body parts (18, 20).  The support ram is connected to a pressurised accumulator so that the support rollers (62) are kept against the pipeline (26) as the plough rises and falls and pitches.  The elevated positions of the arms (69) and the relatively short separation between the two pairs of arms (69) allows the plough to descend and pitch relatively to the pipeline.  In a modification the two beams are joined by rigid bridging structure and the plough body parts are pivotally connected to their respective beams.  In other modifications the supports are dispensed with; or only one is used.

Abstract: ANGULAR POSITION DETECTOR            Abstract of the Disclosure A transducer formed of one or more electrode arrays is positioned in confronting relation and parallel to the plane of rotation of one or more rotating members.  A plurality of phase modulated, two-phase, square wave drive signals of the same amplitude and frequency are applied to each electrode.          The signals are combined at a central node or electrode to form, as a result of the signal, the superposition of the algebraic sum of all drive signal pairs.  Samples of the resultant signal taken at the same frequency and of a duration of less than one-half the duration of the drive signal period provide a multi-step, synchronously detected signal.  The detected signal is a multi-step approximation to a sine wave, the phase angle thereof relative to a timing point being proportional to the angular position of the rotating member.  The amplitudes and phase shifts of the multi-step detected signal are then reduced to a plurality of vectors, from which two orthogonal vectors are produced which may be mathematically reduced to the amplitude and phase angle of the aforesaid sine wave.  The phase angle is transformed or converted into a binary representation of the hand position.          As particularly claimed, this invention pertains to a method of determining the phase angle of a sine wave or the phase angle of the fundamental frequency component of a sine wave approximation with respect to a reference signal of the same frequency and the amplitude of the sine wave comprising the steps of generating the reference signal of known characteristics, generating multiple, periodic, equally spaced samples (K samples) of the amplitude of the sine wave at times which have a known phase relationship to the reference signal, and converting K samples to a single vector describable by an amplitude and a phase, the phase being representative of the relative phase between the original sine wave or sine wave approximation and the reference signal.
