A material for a carrier structure for a group of effective microorganisms, prepared by kneading one part by weight of cement together with a mixture of 2-3 parts by weight of coarse crushed particles prepared by crushing a tourmaline ore to a size of 1 to 20 mm, 2-3 parts by weight of a coarse powder prepared by crushing a tourmaline ore to a size of 1 mm to 100 mu m, and 2-3 parts by weight of a tourmaline powder prepared by crushing a tourmaline powder and sieving the powder with a 100 mu m sieve to obtain an undersize fraction, an EM fermentation material in an amount of 10-100 % by volume of the mixture, and a suitable amount of water to prepare a concrete-like material. This material can be used to reduce water pollution of rivers and, in addition, can improve the efficiency of wastewater treatment equipment.

An external valve operating means (51) that forms a seal (71) around the rotating valve stem (11) of a valve (3) operating under internal pressure is disclosed. This seal (71) prevents the escape of fluids should the valve's primary seals (29, 37) fail. The external valve operating means (51) allows for rotation of the valve stem (11) without removal or compromise of the seal. A stationary operating seal cap (53) is in threaded and sea led engagement with the valve body (5). Upon partial disengagement of the stationary operating seal cap (53), the pressure within the external valve operating means (51) is vented. An external valve stem drive (63) protrudes through the top of the stationary operating seal cap (53). An O-ring (71) forms a seal between the two. The bottom of the external stem drive (63) mates with the rotating valve stem (11) while the top of the external stem drive (77) is shaped so as to allow gripping by a tool. Rotation of the external stem drive (77) via the tool effects rotation of the valve stem (11) while the seal (71) surrounding it is maintained.

An applicator primarily for applying colorants and other treatments to hair comprises a container (2) to which is mounted, preferably releasably, a reservoir (4) for the treatment fluid, the reservoir (4) being provided with at least two, and preferably between six and ten nozzles (10), the bores (14) of which communicate with the interior of the reservoir (4) whereby fluid can be expelled from the reservoir (4) through the nozzles (10) and onto the hair in a controlled manner. The applicator is particularly convenient for applying several narrow bands of colour in the form of "highlights" or "lowlights" to the hair.
摘要:
A structural member (12, 14, 16) for coupling to a similar structural member for forming a framework, the structural member comprising an elongate channel having a web (30) and first and second sidewalls (32, 33), the first sidewall having a transversely extending slot (40) and the second sidewall having a complementary tab (42), wherein the slot and tab are transversely aligned and are positioned and adapted to respectively engage a tab and slot of a similar structural member to thereby couple the structural members together. The dimensions of rail (14) are such that it can interlock with the formations on the upright channels (52, 54). The projections (82, 84) are received snugly within the openings (72, 76) respectively. The projecting legs (88, 86) are received within the slots (70, 74) respectively. The lengths of the slots (80, 78) are such that the end of the rail (14) abuts or lies adjacent to the faces (62) of the upright channels (52, 54). This provides an interconnection of the rail (14) with the upper ends of the upright channels (52, 54).
摘要:
An object of the present invention is to provide a screen frame (214), which is capable of producing clear three-dimensional video images with a simple structure. The screen frame (214) is provided with a frame structure which is like a frame having a window space (216) enclosing a screen (212) at a prescribed distance from the screen (212); the window space (216) is smaller than the screen (212) so that no other part than the screen (212) can be seen through the window space in a prescribed range of viewing angle. When the screen frame (214) is used, the viewer views the screen (212) as if he or she were watching an outdoor scene through the real window and felt a visual depth in the scene. Further, the video images on the screen can be clear by removing influence of peripheral light.

A cleaning device for cleaning magnetic head and photo pickup of a compact disc drive includes a playback-only disc medium received in a recording-enable disc cartridge. The disc medium has a Read-in TOC area for recording medium identification information to indicate a recording-enable disc medium, a User TOC area, a Recorded area, and a No-record area radially sequentially surrounding the Read-in TOC area. Information for managing records on the Recorded area is recorded in the User TOC area. A cleaning sheet for cleaning the magnetic head is attached to entire surface of the disc medium facing the magnetic head. The Recorded area is radially divided into three sub-areas. The inner sub-area has voice messages of "Cleaning starts" or for operating methods recorded therein, the middle sub-area has 30 minutes of silence and has a brush mounted thereto for cleaning the photo pickup, and the outer sub-area has a voice message of "Cleaning ends" recorded therein. The inner and the middle sub-areas are identified as a magnetic track No. 1 and the outer sub-area a magnetic track No. 2.
摘要:
A hydraulic circuit system for a jack comprises an inlet circuit, a return circuit and an overload protection circuit with a piston-cylinder assembly (4,10), a sequence valve (B), a safety valve (D) and a relief valve (C), the inlet circuit extending from an outer reservoir (2) via a check valve (A1) to an oil chamber (3) of a manual pump (20), the oil chamber (3) being connected to an inner oil chamber (41) formed in the piston rod (4) via another check valve (A2) to form a closed circuit. The oil chamber (3) of the pump (20) is connected to an inner reservoir (1) in the hydraulic cylinder (10) via a sequence valve (B), and the inner reservoir (1) is connected to the outer reservoir (2) via a check valve (A3). When the maximum effect capacity of the oil chamber (3) of the pump (20) is greater than or equal to that of the inner oil chamber (41) of the piston rod (4), a single touch of the pump (20) can raise the hydraulic jack to a required loading position under no load or light load conditions.
摘要:
A fresh air heating unit has a casing (2) containing a stale air flow path (25) and a fresh air flow path (14). Combusted gas products from a gas burner (29) are mixed with the fresh air to heat it to a desired temperature before it is discharged into an enclosure. The two paths extend through a heat exchanger (15) and the rate of flow of stale air driven by a fan (26) through the casing is substantially equal to the rate of flow of fresh air driven through the casing by a second fan (21). As the rate of flow of fresh air from the casing into an enclosure is substantially matched by the rate of flow of stale air from the enclosure, and heat is transferred between the two air flows by the heat exchanger (15), a total replacement of air in the enclosure at a relatively high rate can be sustained in an economically viable manner. The level of noxious combustion products in the enclosure and produced by the gas burner (29) can thus be kept beneath that regarded as harmful by health authorities.

摘要:
A multi-use die system (10) is provided having a die holder (20) with reference marks (20r, 20c) disposed circumferentially and radially along the longitudinal axis of the holder, and a multi-use die plate (30) for magnetic affixation to the die holder (20) which impresses a pattern onto a material blank. The die plate has a straight and angular reference marks (60, 62) disposed thereon which are adapted to align with the radial and longitudinal reference marks on the die holder so as to properly align the die on the die holder (20) at a predetermined position. In a straigth rotary die system, the die is aligned such that the straight reference mark (60) on the die is aligned with the respective corresponding radial and circumferential references on the die holder. In the angular rotary die system, the die is aligned such that the angular mark (62) is aligned with the corresponding radial and circumferential references on the die holder.
