Abstract: A differential relay for protecting a power apparatus portion of a power system, such as a bus line, includes incoming and outgoing power lines on which incoming and outgoing currents are present. The incoming and outgoing currents of each phase are applied through current transformers and then through filtering and normalizing circuits prior to application to the differential relay. The differential relay includes a circuit for determining the presence of an external fault, and maintains security by avoiding a tripping action of the relay for said external faults.

Abstract: Apparatus for non-invasive reading of subcutaneous material, including in one package light emitters of a wavelength capable of illuminating subcutaneous material, light detecting elements responsive to the illuminated material and prerecorded material, whereby the apparatus makes a comparison between the currently illuminated material and the prerecorded material.

Abstract: The protecting apparatus includes a circuit for automatically and continuously determining the difference voltage between the voltage at the input side of a connecting circuit breaker and the voltage at an output side thereof between an electric generator and an associated power system, following initiation of closure of the connecting circuit breaker. The difference voltage is representative of the voltage angle of the generator relative to the electrical system. The difference voltage is compared against a reference value, which is selected such that a voltage angle value greater than the reference value will result in damage to the generator and/or the electrical system. An output signal is developed which can then be used to trip circuit breakers serving the electrical system if the reference value is exceeded by the difference voltage.

The roller element has a faceted peripheral edge, each facet being of equal length, with approximately 12 facets per unit. Also, a quick-release roller assembly for use in a similar endless conveyor system includes a steel shaft on which roller elements are mounted. The shaft has a first opening in one end to receive a connecting pin element from a first chain and a second opening in the other end thereof which receives a connecting pin element from a second chain. Bushings are positioned in both of the shaft openings for receiving the connecting pin elements. In the one opening, a spring element is positioned between the bushing and the bottom end of the opening. The shaft has a slot in the side surface of the shaft, opening onto the first end of the shaft.

Abstract: The method and apparatus includes a length of hollow suture material in which an alternating plurality of radioactive seeds and intermediate spacers are located. The suture member includes a portion which extends a substantial distance beyond the first radioactive seed in the suture member. The combination of the hollow suture member, the radioactive seeds and spacers is then moved into a insertion needle through a hub end thereof, to the point where the free end of the hollow suture member extends past the tip end of the insertion needle. The suture member then is pulled through the hollow insertion needle until the first radioactive seed in the suture member is positioned at the tip end of the insertion needle. The extended portion of the hollow suture member is then severed in the vicinity of the tip end of the insertion needle. The loaded insertion needle is then inserted into the prostate of the patient.

Abstract: A clutch shoe (10, 31, 61, 62, 70) for a clutch assembly (1), the clutch shoe having a clutch drum engaging portion (12, 71) having a clutch drum engaging face (72); the clutch shoe including a flange (14, 75) integrally formed with an extension extends substantially at right angles from the clutch drum engaging portion about a fold line (76). The method of forming the clutch shoe comprises stamping blanks from sheet steel and bending the blanks about the fold line (76) so as to provide the integrally formed flange (14, 75) extending substantially at right angles from a clutch drum engaging face (72) of the clutch drum engaging portion (71).

Abstract: A cleaning head for carpets, walls or upholstery, including a rigid, exterior, open-bottomed main body which defines the surface subjected to the cleaning process. Mounted within or adjacent to the main body portion coplanar with the bottom thereof is the fluid-applying device, which includes a slot at an acute angle to the plane of the bottom of the body located adjacent the plane of the bottom of the body, configured such that the fluid is applied in a thin sheet which flows out of the slot and into the upper portion of the surface to be cleaned and subsequently into the vacuum source for recovery.

Abstract: A pump used in a power toothbrush for fluid delivery to the bristles. The pump moves fluid provided to it to a dispensing valve located in the brushhead. The pump includes a pump chamber with a piston ball located therein. The piston ball moves within the chamber in response to movement of the brushhead, moving fluid out a discharge end of the pump chamber under pressure. The pump includes a fluid exit channel which connects the discharge end of the pump chamber with an opening in the brushhead in which the dispensing valve is located.

Abstract: The system for automatically dispensing medications or other medical elements includes several groupings, i.e. vaults, of storage members, each vault containing approximately 100 individual cartridges, which each contain packages of unit-of-use doses of a given medication or other medical supply, such as syringes. Each storage member includes an ejector which ejects selected medications/supplies to a supply trough. The packages in the trough are moved to a central collator, which dispenses them to a bin receptacle which has been moved underneath the collator and which is typically identified with a particular patient. Information concerning medications/supplies for a particular patient is stored in a system database and used to determine the particular medications/supplies dispensed into a given bin. Bar coding is used to maintain control over the bins, and the medications, forming a closed information/control system.

Abstract: The flatbread maker includes a support structure which has a base portion, a short rear portion and an upper portion, wherein the upper portion angles upwardly as it extends forwardly from the rear portion, wherein the base portion includes a central track which extends inwardly from the front edge for receiving a roller element portion of an actuating arm. The actuating arm is generally L-shaped, having a roller element at the joining portion between vertical and lower leg portions thereof, the roller element being configured and arranged to slide along the track when the vertical leg portion of the arm is rotated downwardly, such that the roller element moves along the track and the free end of the lower leg moves upwardly, forcing a lower flatbread plate which is hinged to the rear portion of the support structure to rotate thereabout into a position adjacent an angled lower surface of the upper portion. This results in the pressing, heating and partial cooking of the flatbread.

Abstract: A fiber-optic transceiver receives from and transmits to an associated electronic terminal device, such as a protective relay, digital data signals. Fiber-optic transceivers can be positioned at opposite ends of a connecting fiber-optic line. Power for each transceiver is obtained from its associated electronic device. The transceiver includes a transmit section, a receive section, a handshake section to provide feedback of control signals which may be required by the associated electronic terminal device, and a voltage supply section. A particular optical coding arrangement is used to convert the digital data signal from the terminal device to a series of optical pulses, wherein a pair of optical pulses represents a rising edge of the digital data signal from the electronic device, while a single pulse represents the falling edge of the data signal. Additional pairs of pulses and single pulses may follow the initial one, depending upon the length of the high and/or low portions of the data signal.
