Abstract:
An electric motor assembly including a mechanism for mounting a module housing end on a motor housing end, and a mechanism for drivingly connecting a module shaft end to a motor shaft end. The assembly further includes a mechanism for preventing the module housing from rotating relative to the motor housing, and a mechanism for slidably attaching for shaft axis direction movement relative to each other the module housing and the motor housing. The module shaft end and the motor shaft end are located relative to their respective housings so that they can be drivingly connected to each other without the module housing and the motor housing interfering with the connection.
Abstract:
A tray-positioning device comprises a driving unit and a positioning unit, wherein the positioning unit provides a plurality of sidewalls that correspond to a plurality of upper sidewalls of a tray. By allowing the driving unit to move the positioning unit toward the tray or vice versa that said individual upper sidewalls are in close contact with the corresponding sidewalls, the tray-positioning device is capable of providing precise positioning for the tray.
Abstract:
An electric motor having a no-adjust starting switch. An actuator button of a starting switch assembly is slidably positioned in a switch housing mounted to an end frame of the motor. As a rotor shaft and associated centrifugal governor which engages the actuator button rotate, there is minimal wobbling of the actuator button during motor start-up and motor operation.
Abstract:
This invention relates to a C type lamp string improvement, comprising a lamp holder, a first contact piece, a second contact piece and a cord, wherein said lamp holder is such designed as to be integrally molded together. Said first contact piece and second contact piece may contact each pole of the bulb respectively, and one end of each has a sharp point for piercing the covering of the cord while contacting the core of the cord to achieve good conductivity, and said second contact piece has a proper number of projecting points at intervals equivalent to the pitches of the bulb thread to substitute for the conventional lamp holder thread. For manufacture, the first step is to insert the first and second contact pieces into the mold for making said lamp holder, and then place said cord within said injecting mold to enable said first and second contact pieces to pierce the covering of said cord with the sharp point, and wait until the integration of the injecting mold then the lamp holder will be integrally molded while cord and first and second contact pieces are integrated within the lamp holder.
Abstract:
A valve suitable for lawn and garden irrigation with a fluid inlet and two fluid outlets and a means for switching the flow of water from one outlet to the other based upon a predetermined flow of water. A plurality of valves may connected in series to irrigate several garden areas by connecting the inlet of each valve with the second outlet of the previous valve, except the inlet of the first valve which communicates with a water source.
