Abstract: ABSTRACT           A meter terminal unit, for acquiring information and transmitting the acquired information to a central reading and control unit over utility power transmission lines, includes a transmitter portion for synthesizing and modulating carrier waveforms, the frequencies of which are selectable by command data contained in frequency rotation and address fields of a command received from the central reading and control unit. The meter terminal unit receives and decodes the command and adds, in modulo form, the contents of the frequency rotation field to the contents of a portion of the address field to obtain a resultant sum which uniquely identifies the selected waveform. This sum is used to access a portion of a read only memory (ROM) having the selected waveform stored therein in digital data form. The selected waveform is reconstructed by outputting the digital data from the ROM to a digital to analog converter. The reconstructed carrier waveform is then phase-shift-keyed by the acquired information, which has been placed in digital form, and the resultant modulated carrier is transmitted to the central reading and control unit over the power lines.

Abstract: A BYTE ORIENTED DC BALANCED (0,4) 8B/10B  PARTITIONED BLOCK TRANSMISSION CODE                 ABSTRACT            A binary DC balanced code and an encoder circuit for effecting same is described, which translates an 8 bit byte of information into 10 binary digits for transmission over electromagnetic or optical transmission lines subject to timing and low frequency constraints.  The significance of this code is that it combines a low circuit count for implementation with excellent performance near the theoretical limits, when measured with the commonly accepted criteria.  The 8B/10B coder is partitioned into a 5B/6B plus a 3B/4B coder.  The input code points are assigned to the output code points so the number of bit changes required for translation is minimized and can be grouped into a few classes.

Abstract: ABSTRACT           A scanning and/or tracking mechanism for use in airborne obstacle avoidance optical radars operating in the infra-red region.  The radar beam is scanned by passing it through a pair of in-line rotating optical wedges which rotate around the boresight axis and which are transparent to the infra-red radiation.  The wedges are separately driven by servo systems including hollow shaft torque motors with the wedges mounted in the hollow shafts thereof.  A high resolution and low backlash shaft position encoder is utilized comprising encoding discs directly driven by the optical wedges and including a novel decoding system.

Abstract: ABSTRACT          METHOD OF AND APPARATUS FOR REPAIRING DRAINS AND UNDERGROUND PIPELINES      For repairing a drain or pipeline defect (which in the illustrated case is a major collapse, but may be a minor leak, hole or other defect), after cleaning by high pressure water or other methods and/or after reaming out the drain, an ejector body 20 is pushed by rods or is drawn into place by means of a hauling cable 80 until its leading end is to one side and its trailing end is to the other side of the defect.          Thereupon, sealing rings 38 are inflated to seal the body's ends, and the components of a multi-component hardening composition are supplied by way of ducting 58 so as to meet and mix in the body 20 and emerge through holes 54 to fill the entire defect and any registering voids in the surrounding earth.          Before the composition is fully set, the body 20 is displaced along the drain or pipeline, and the re-maining hardening compound serves to replace the defective or missing drain or pipeline material.          After withdrawal of the body 20, the repair may be reamed again, and/or polished.

The  actuator  is  double acting and comprises a piston reciprocable in a cylinder on a guide tube, so that the maximum volume of the chamber below the piston is greater than that of the chamber above the piston,  and the lower working area of the piston is greater than its upper working area.  Ports in the cylin-der above and below the piston are connected to a valving and control  arrangement,  and  a  source  and receiver of hydraulic  fluid  and  an accummulator are also provided.

Abstract: ABSTRACT OF THE DISCLOSURE     A domestic pillar faucet has a main flow path and a control flow path, both connected to the same inlet. A diaphragm supports a valve member for displacement between a position in which the valve member is held open and a position in which the valve member closes the main flow path.   Displacement of the diaphragm is controlled by fluid from the control flow path.   The control flow path includes an inlet valve and an outlet valve and the section of the control flow path between the valves communicates with the diaphragm.  By opening the outlet valve, the force on the diaphragm is reduced and the valve member will open.  By closing the outlet valve and opening the inlet valve, the force on the diaphragm is increased and the valve member will close.       The valves are operated by a lever through push buttons.  The faucet is thus operated in a power assisted manner, not needing the dexterity required when opening or closing conventional faucets.

Abstract: ABSTRACT OF THE DISCLOSURE          A chopping type electrical converter having a primary circuit utilizing controlled rectifiers for chopping the input voltage, a secondary circuit for providing a DC output voltage, and a control unit which continuously monitors current flow in the secondary circuit and delays trigger pulses to the controlled rectifiers in the primary circuit whenever it is unsafe or undesirable to trigger them. In a preferred embodiment, the controlled rectifiers are mounted in series-connected pairs with a step-down transformer for each controlled rectifier. The number of pairs and the interwoven triggering order of the controlled rectifiers enables high voltage and high frequency operation with minimal stress on the converter components. The control unit prevents each member of each pair of controlled rectifiers from being triggered whenever the other member of the pair is still conducting, or whenever current is flowing in the secondary winding of the transformer associated with the controlled rectifier. The control unit also provides output voltage regulation and current limiting, and shuts down converter operation during overload or malfunctions. Accoustical noise suppression is incorporated, wherein the converter operating frequency is continuously modulated even under a constant load to spread the converter noise throughout the audible spectrum and thereby submerge it beneath the noise background.

The base strips 10 are cut to length with formed end regions 11 which are mounted on a mold part 15 so that a midregion of base strip 10 spans an injection mold cavity 18.  Pins 21 within mold cavity 18 locate base strip 10 in a plane spaced from the cavity balls so that the cavity surrounds the midregion of the base strip.  The injection molded resin cladding 25 also surrounds the midregion of base strip 10 and provides raised resin shoulders 20 extending along longitudinal side edges of the base strip.  The surrounding engagement of  cladding  25  secures  resin  shoulders  20 against transverse movement relative to the base strip.  Resin clad base strip 10 is then assembled with a cushion 26 and a cover 30 that is wrapped and sealed to a seam region 23 of resin cladding 25 between raised shoulders 20.  Alternatively, claddings 25 can be molded at spaced intervals on a continuous length of base strip 10 which is thereafter cut and punched to form discrete lengths of clad base strip for assembly with a cushion and wrapper.
