摘要： A liquid level presence detection circuit includes a selectively gatable TRIAC serially connected with a load and triggered into conduction by twin sensitive-gate SCR's connected anode-to-cathode with the gates of the SCR's connected to voltage divider circuits which provide gating current to the SCR's in response to the presence of a conductive liquid bridging the two spaced apart contacts of a liquid presence detecting probe. The circuit is used in wet-niche type lamp assemblies that provide underwater illumination in swimming pools and the like and in which cooling is effected by the surrounding liquid. The detection circuit advantageously interrupts the flow of electrical energy to the lamp when the level of surrounding liquid falls below a predetermined level to prevent over-temperature operation of the lamp and consequent damage thereto and resumes the flow of electrical energy to the lamp when the level of the surrounding liquid increases to a safe level to permit adequate cooling thereof.
摘要翻译：液位存在检测电路包括与负载串联连接并由双敏感栅极SCR连接的阳极至阴极触发导通的选择性可对准TRIAC，其中SCR连接到分压器电路的栅极，其向SCR的栅极提供栅极电流响应于存在桥接液体存在检测探针的两个间隔开的触点的导电液体。该电路用于在游泳池等中提供水下照明并且由周围液体进行冷却的湿式小型灯组件中。当周围液体的水平下降到预定水平以下时，检测电路有利地中断了对灯的电能的流动，以防止灯的过热操作并对其造成损害，并且当电平达到电平时恢复电能流向灯的周围液体增加到安全水平以允许其充分冷却。

摘要： A platform for supporting a motor-pump combination is molded as a unitary structure and includes a primary support and a detachable secondary support. The primary support includes a supporting surface formed at a first radius, and the secondary support includes a supporting surface formed at a second radius and a cavity adapted to receive the primary support. The platform, which retains the cost advantages attendant to one-step molded structures, may be readily converted from a platform for supporting a motor having a first radius to a platform for supporting a motor having a second radius by detaching the secondary support from the platform and mounting it over the primary support.

摘要： A test plug assembly for insertion into a housing for preventing liquid under pressure from flowing therethrough includes an assembly body with an undersurface shaped and dimensioned to mate with a shaped upper portion of the housing. A plurality of flanges which project from the outer surface of the body are located and spaced apart so that the studs can pass between the flanges when the body is inserted into the housing and so that the uppermost surface of the flanges will engage the lowermost surface of the studs when the shaped upper portion and undersurface are in contact and the body is rotated relative to the housing. The body further includes a gripper for gripping the body so it can be rotated into engagement with the housing.A method of pressure testing a fitting for a liquid inlet includes the steps of installing an inlet fitting on a pipe which is located beneath the underwater surface and which communicates with a source of liquid under pressure, mounting a liquid jet housing on the fitting by forming a leak proof connection between the fitting and housing, inserting a removable plug into the housing which is capable of preventing liquid from passing through the housing at a testing pressure, introducing liquid at a testing pressure into the housing through the inlet fitting, and replacing the removable plug with the housing's normal internal assembly.

摘要： A threaded lid for closing the opening in a pump housing having a body portion and a gripping formation defined by a ridge on the body portion having a central portion and projections extending beyond the central portion. A juncture between the central portion and each of the projections varies gradually from a rounded angle at one terminus of the juncture to a gently sloping ramp at the other terminus of the juncture, so that a simple elongated tool such as a stick may be placed between the projections of the gripping formation and rotated to loosen the lid, but not to tighten it. Furthermore, the mildly curved S-shape provides surfaces which conform to the hand to enable substantial manual loosening force to be applied comfortably to the lid, whereas the surfaces of the gripping formation engaged by the hand to tighten the lid are not conducive to the application of a substantial amount of manual force.

摘要： A skimmer assembly for use in swimming pools in which a skimmer housing is provided with a skimming inlet and a drain inlet for receiving water from a pool. An outlet is also provided for connection with a vacuum source for discharging water from the housing. A floating weir is disposed in the housing for regulating the amount of water entering the housing from the skimming inlet and a filter basket is disposed in the housing with its open end communicating with the skimming inlet and a wall portion communicating with the drain inlet. An adaptor member and a cover plate cooperate with said basket for selectively controlling the flow of water from said skimming inlet to said outlet. The basket is adapted to attain a plurality of positions in the housing for regulating the flow through the drain inlet to the housing, and a sealing assembly is provided on the weir and the basket for sealing off flow through the skimmer inlet when the level of water in the pool falls below a predetermined value. The weir is adapted to accommodate an adaptor assembly for attaching a vacuum hose to the assembly for vacuuming selected portions of the pool under the vacuum created by the aforementioned vacuum source. A valve relief mechanism is provided on said weir for permitting water flow from said skimming inlet in the event the drain inlet becomes blocked when the weir is in its sealing position.

摘要： A wet-niche type lamp for providing underwater illumination in a swimming pool or the like includes an over-temperature protection circuit which interrupts the supply of electrical energy to the lamp when the level of the cooling water surrounding the lamp drops below a predetermined level. The circuit includes thermistor mounted in an heat exchange relationship with the surrounding water so that heat energy generated in the thermistor, as a consequence of the current flow through it, is normally transferred to the surrounding water. Should the level of the surrounding water drop below that of the thermistor, the thermistor heat energy quickly evaporates any remaining water film on the exterior surface of the thermistor to allow its temperature to rise. The control circuit, in response to the temperature increase, interrupts the flow of electrical energy to the lamp to prevent over-temperature operation.
