An evaporator assembly for incorporation into an air conditioning apparatus, particularly for automobiles, comprises a main air duct (2) defining an air inlet (6) and outlet (10), means (22) to force air through the main air duct (2), a heat exchanger (12) disposed on the main air duct (2), and an air feedback duct (18) which links the main air duct (2) downstream of the heat exchanger (12) with the duct upstream thereof, whereby a proportion of the air which has passed through the heat exchanger can be recirculated, via the feedback duct (24), to pass through the heat exchanger (12).

A differential cam mechanism for control of revolving tools (fig. 1& 2) comprises an outer pipe (2) rotatably mounted in a static housing (7), an inner pipe (1) rotatably and co-axially mounted inside the said outer pipe (2), a slot (10) and a cam (12) provided on the flanges (3) and (4) located at one end of the said co-axial pipes, a cam follower/tool holder (11) having one of it's ends slidably engaged in the said slot (10) and the other end slidably engaged with the cam (12), a tool (15) fixed at one end of the cam follower/tool holder (11), the free ends of the said pipes (1,2) provided with drive means (16,17) for rotating the said pipes independent of each other at desired variable speeds in both directions.

In order to carrry out a two-stage fire extinguishing operation including a cooling fire extinguishing operation and an oxygen deficiency fire extinguishing operation using a fire extinguishing gas, a cylinder filled with a liquefied gas of carbon dioxide is used, and a firing pin unit for breaking a seal member of the chlinder, a retainer for maintaining the firing pin unit in a non-opereted state and a retainer operating device for automatically operating the retainer on the basis of stored temperature data are provided. The retainer is fixed at a head portion thereof by bolt screwed to the upper surface region of a fixing member, and leg portions of the retainer are fitted in an upper recess in a shaft to a lower end portion of which a pin is fixed. The retainer operating device consists of a retainer turning member provided with projections on one end portion thereof. These projections are positioned on the inner side of the two leg portions of the retainer, and the retainer operating device is turned when a spring of a shape memory metal contracts at a predetermined temperature, to cause the projections to open the leg portions of the retainer, and the pin to be driven.
摘要:
An electric rotary razor including at least one outer cutter (36) which has slits (37a) for whisker entry and at least one inner cutter (38) having a plurality of cutter blades (40). Each one of the cutting blades (40) is inclined in the rotational direction of the inner cutter (38) and has a cutting edge surface (41) at its upper end that slide on the bottom surface of the outer cutter (36). The cutting edge surface (41) is thinner than the cutter blade (40) or the cutter blade (40) can have a recess (40a) beneath the cutting edge surface (41). Thus, sheared whiskers are prevented from sticking to the cutter blade (40) of the inner cutter (38).
摘要:
An electric razor (10) with a fan assembly (42) installed under and coaxially with a rotary inner cutter. The whiskers entering through slits (37a) or an outer cutter (36) are cut by the inner and outer cutters (38,36), and the sheared whiskers are blown by the fans (44) of the fan assembly and collected in a receptacle element (26) provided in the razor. Thus, the shaving debris does not stick to the inner and outer cutters (38,36), making it easy to clean the razor.
摘要:
An electric razor with a cleaning cover (12) fitted on the inner cutter (10). The cleaning cover (12) has slits (18) which correspond in position to the blades (16) of the inner cutter (10), and the blades (16) of the inner cutter (10) can pass through the slits (18) when the cleaning cover (12) is fitted on the inner cutter (10); and once the cover (12) is fitted on the inner cutter (10), the surface of each blade (16) is in contact with the inner surfaces of the slits (18). The razor is used with the cleaning cover (12) on, and when after shaving the cleaning cover (12) is lifted, the facial hair that has been cut and is adhering to the blades (16) of the inner cutter (10) are removed by the cleaning cover (12), thus cleaning the inner cutter (10).
摘要:
Lentille torique à correction de désaxage et dont la ou les surfaces présentent une topographie optique induisant un effet de profondeur de champ sur l'oeil et permettant à l'axe des puissances de la lentille de s'aligner sur celles de loeil de l'utilisateur de sorte que toute erreur d'alignement est annulée si la lentille est désaxée par un degré ou plus. La lentille est suffisamment mince pour permettre une transmission suffisante d'oxygène et s'adapter de manière satisfaisante à la morphologie de l'oeil de l'utilisateur. La topographie optique qui induit l'effet de profondeur de champ comprend soit la topographie asphérique, des fonctions de courbes splines, une optique à diffraction utilisant des prismes miniatures, soit une optique à biréfringence.
