Abstract: In an electromagnetic switch for a starter motor, power produced by friction from repeated opening and closing of the stationary and movable contacts 22, 26 is prevented from entering between the sliding parts of the movable iron core assembly 4, thus ensuring smooth sliding motion of the movable iron core assembly at all times, and the penetration of external water into the spaced defined by the stationary and movable iron cores 9, 4 and a shaft member 20 is effectively prevented. The shaft member is disposed inside the annular stationary iron core for movement in the axial direction. An insulating sleeve 21' is fitted over the shaft member and fixed thereto for movement therewith. The insulating sleeve has a cylindrical outer peripheral surface of a diameter slightly smaller than the inside diameter of the radially innermost surface of the stationary iron core, and the outer peripheral surface of the insulating sleeve has an axial length D larger than the axial distance between the stationary contact 22 and the stationary iron core 9 so that there is maintained a limited constant clearance c between the insulating sleeve and the stationary iron core at all times irrespective of the axial position of the insulating sleeve relative to the stationary iron core,   so that the space defined by the stationary and movable iron cores is substantially sealed. The electromagnetic switch includes a cylindrical housing 8 accommodating an electromagnetic coil 12, the housing having one open end closed by a cap 11 to which stationary contact 22 is firmly attached. An annular stationary iron core 9 is disposed in and fixed to the housing. The movable iron core assembly 4 is disposed inside the electromagnetic coil and includes shaft member 20 connected with a movable iron core 16 the axially slidably fitted in the electromagnetic coil in face-to-face relation with the stationary iron core for movement towards and away from the stationary iron core. Movable contact is mounted on one end of the insulating sleeve and thus electrically insulated from the movable shaft, and contacts the stationary contact 22 on the axial movement of the shaft member caused by energization of the electromagnetic coil.

Abstract: A fluid flow sensing device comprises first and second p-n junctions (T.D). one (T) of which is arranged to be disposed in the fluid flow to be measured and the other of which is arranged to be disposed at a position such that its temperature depends only on that of the fluid. An amplifier (20) monitors the voltage drop across the first p-n junction. A comparator (16) compares the measured voltage drop across the first p-n junction with a reference level (V<sub>RE+2</sub>) to provide a feedback voltage (V<sub>c</sub>) which is used to control the heating of the first p-n junction such as to maintain the temperature of that junction constant irrespective of variations in the fluid flow or the fluid temperature. A current is passed through the second p-n junction and the voltage drop across it is monitored and compared with the feedback voltage (V<sub>c</sub>) to provide a signal which is a function of fluid flow alone.

Abstract: In the representative embodiments of the new and improved apparatus disclosed herein, a string of full-bore well tools are arranged to be suspended from a pipe string in a well bore penetrating an earth formation in flow communication with the well bore. A full-bore packer coupled to the pipe string is operated from the surface for isolating the well bore interval below the packer from the fluids in the well bore thereabove. To test the formation, a test valve coupled to the pipe string is selectively operated from the surface for opening the pipe string to the flow of formation fluids from the isolated well bore interval. Thereafter, when it is desired to obtain a sample of the formation fluids flowing in the pipe string, the new and improved full-bore sample-collecting apparatus coupled to the pipe string is selectively operated from the surface to admit the fluids in the pipe string into an annular sample chamber within the new and improved apparatus. Means included in the sample-collecting apparatus are further operable only in response to the admission of formation fluids into the sample chamber to regulate the flow rate at which these fluids are admitted into the sample chamber so as to not disturb the fluid sample any more than is necessary. Thereafter, other means included with this apparatus operate only in response to filling of the sample chamber for trapping the fluid sample.

Title: Hair dryer
Inventor: YANG TAI-HER
IPC: A45D20/12
Filed: 1987-11-25
Abstract: This is an improved structural design for a hair dryer. Its feature is that on the housing wall (1) near the blowing opening (10) rim of the hair dryer, make the exhaust holes (2) to blow out an air flow. They are in an opposite direction and inclining to the out blowing air flow. When a blowing opening (10) of a dryer is blocked, they produce an outflow function. They improve the phenomenon of overheating or burning out an electric heater in case a blowing opening of a dryer is blocked. One step ahead, an alternative design is to make limited pressure flaps (3) on the outer part of exhaust holes. When the pressure inside the exhaust holes becomes excessively pressured by a blocked or half-blocked blowing opening, the flaps (3) may be pushed open. When over-loaded, the highly pressured air flow may be released through the exhaust holes. 
     One more step ahead, it may be designed to have an adjustable mixing flow air-window at the same time. By applying the siphoning effect, it may inhale the outer cool air and blow it into the back section of the air blow blades of a hair dryer enabling to adjust the heated air flow temperature by a mixing method. 
     It is different from a traditional method of adjusting heat producing volume of an electric heating wire.
