Abstract: An inhaler in use for inhaling pharmaceutical powdered preparations through mouth and making the same reach a trachea, bronchi and pulmonary cells. The inhaler has a general form bent at a predetermined angle, preferably, at 60 degrees, comprising a hollow body (1), a capsule holding portion (2) for receiving and holding a capsule (3), and an inhaling section (9). The capsule holding portion (2) is rotated relatively to the hollow body (1), whereby the capsule (3) is divided into two including a barrel and a head, so that the powdered preparations can fall into the hollow body (1). The powdered preparations, which have fallen into the hollow body (1) can be inhaled into a human body together with intake air flowing in through air flow-in openings provided in the capsule holding portion (2) by breathing with the mouth being applied to the inhaling section. The capsule barrel which has fallen into the hollow body (1) is prevented from being inhaled into the human body due to the presence of a porous member (13).

Abstract: Ultraviolet radiation is the wavelength range between 150 and 300 nanometers, which both generates ozone (O3) and has a germicidal effect both in ambient air and in a pure oxygen atmosphere, is performed in a highly energy-efficient manner, by utilizing a low-voltage, low-pressure gas discharge lamp, by using a radiation-transparent quartz tube, by equipping it with a long-lasting sintered electrode pair and filling it with a mixture of gas vapor and mercury vapor, by disposing a circuit device between the mains and the gas discharge tube which rectifies the mains alternating current and effects smoothing voltage multiplication, and by coupling this circuit device with an automatic, dry-switching commutator device for the direct current of the gas discharge lamp, in order in principle to avoid a mercury-vapor dissociation (cataphoresis) which would reduce the effectiveness of the radiation. As a result of the direct current operation, the energy efficiency of the UV radiation generator is improved by up to 30%, as compared with direct operation of the gas discharge lamp with alternating current and a standard alternating current choke, because of the reduction in heat losses both in the gas discharge process and in the voltage multiplier choke.

Abstract: A closure for a cable splice is disclosed which comprises a main sleeve (12) and two end structures (14, 16). One end structure (14) is secured to the sleeve (12) by means of a locking ring (34) screwed onto a cap (32) of the end structure (14). The sleeve (12) has an internal flange (18) and the cap (32) has an external flange (42) which lies adjacent the flange (18) of the sleeve (12). Engagement between the flanges (18. 42) prevents the end structure (14) being withdrawn from the sleeve (12). The end structure (16) is connected to the sleeve (12) by means of a split clamping ring (90) which is held in place by a tightening ring (98). Once the ring (34) has been loosened and slid back, and the clamping ring (90) and tightening ring (98) removed, the sleeve (12) can be slid back over the cable (C1) to provide access to the splice (S).

Title: Cyclic aeration system for submerged membrane modules
Inventor: COTE PIERRE
IPC: B01F33/40
Filed: 1999-10-07
Granted: 2004-07-08
Abstract: An apparatus is described for cleaning or inhibiting the fouling of a plurality of membrane modules 20 immersed in tank water 18 in a tank 12. Air is supplied through aerators 38 to produce a flow of bubbles 36 effective to clean or inhibit fouling of the membrane modules. The flow of air is alternated between a higher flow rate and a lower flow rate, the lower flow rate being less than one half of the higher flow rate, in repeated cycles of not more than 120 seconds in duration while the permeate is withdrawn through the membrane modules 20. This produces transient flow conditions in the tank water 18, the tank water 18 being accelerated or decelerated for much of each cycle so that it is rarely in a steady state during permeation. This gives rise to efficient cleaning of the membranes without overloading the aerator system. The flow rates are controlled by a set of valves 254 and a controller 256.

Title: Scroll type compressor with injection mechanism
Inventor: YOSHII YUJI
IPC: F04C29/04
Filed: 1992-04-02
Granted: 1996-12-24
Abstract: The present invention is directed to a scroll type compressor having an injection mechanism in which a part of the refrigerant flowing from the condenser is combined with the refrigerant in the intermediately located fluid pockets of the scroll elements in order to increase the amount of heat radiation from the refrigerant in the condenser without increasing the capacity of the compressor and in order to prevent operation of the compressor at a thermally severe condition. The injection mechanism includes a horseshoe-shaped groove formed between a circular end plate of a fixed scroll and an end portion of a casing adjacent to the circular end plate, a pair of axial conduits formed through the end plate of the fixed scroll and an axial hole formed through the end portion of the casing. The refrigerant is conducted to the intermediately located fluid pockets of the scroll elements via the axial hole, the groove and the axial conduits which are connected in series for fluid communication. In accordance with the present invention, the injection mechanism is easily assembled, and the thermal influence of the high temperature discharged refrigerant gas in the discharge chamber of the injection mechanism is negligible so that the operation of the compressor at a thermally severe condition is effectively prevented.
