Date Mar. 24, 1988.Method for cleansing gas from solid, liquid and/or gaseous contaminants, by bubbling the gas through a liquid bath (32), and by introducing the incoming gas into a distribution means (14) and causing the gas to pass in part-streams through a multiple of inlet orifices (64) located at progressively increasing depths beneath the surface (34) of the liquid (32). With increasing inlet pressure an increasing number of inlet orifices (64) are utilized for an increasing number of part-streams. The gas flow is passed from respective inlet orifices (64) through connecting means (24, 26, 28) to outlet orifices (31) located at a considerably higher height level (h) than corresponding inlet orifices (64). The gas flow is caused to flow out through venturi nozzles (28) and/or to strike against impinger or striking surfaces (39) with a minimum pressure drop corresponding to said height differential (h). In this way full operational pressure is immediately achieved, as soon as gas is passed out through any of the inlet orifices (64), and an intense mixing of gas and liquid as well as a high cleansing efficiency are guaranteed.

Granted: 1998-09-29
Abstract: For the low temperature fractionation of air with variable oxygen production, compressed, prepurified, and cooled air (conduit 5) is initially fractionated in the high pressure stage 10 of a two-stage rectification 9.          The thus-produced bottom liquid is further separated in the low pressure stage 11.  Liquid nitrogen 14 from the high pressure stage 10 and liquid oxygen from the low pressure stage 11 can be stored intermediarily in tanks 35 and 32.  An enriched liquid air tank 40 is additionally provided in order to store bottom liquid 12 from the high pressure stage 10.  In case of increased oxygen production, the internal rate of flow in the high pressure stage 10 can be raised; and simultaneously the internal rate of flow in the low pressure stage 11 and the reflux ratios in both rectifying stages 10, 11 can be maintained constant.  The constant reflux ratio in the low pressure column permits the argon bubble concentration to remain high, permitting a substantially rate of separation of the argon in a crude argon column.

Inventor: MIURA KATSUNORI
IPC: H03K3/0232
Filed: 1990-07-17
Granted: 2000-02-22
Abstract: A monostable multivibrator is formed in a monolithic integrated circuit along with a voltage controlled oscillator (VCO). The VCO and the monostable multivibrator respectively includes capacitors. A center frequency of the VCO is controlled by a control signal from a low-pass filter which receives an output of a phase comparator. A current from a constant current source circuit is adjusted to be in proportion to a level of the control signal. The capacitor of the monostable multivibrator is charged by the current thus adjusted from the constant current source circuit in response to a trigger pulse. A period from a time when the charge is started to a time when a charged voltage of the capacitor reached a predetermined value becomes a metastable period of the monostable multivibrator.

A first gear member is fixed to the support tube. an extendable strut, which includes a hollow upper strut member pivotally connected to the first gear member and a Lower strut member slidably received in the upper strut member, pivots about the first gear member between a lowered position and an elevated position. An adjustable foot rest assembly is releasably clamped to the lower strut member. The leg rest assembly also includes a mechanism for extending the foot rest in reaction to the strut being pivoted toward the elevated position. The extending mechanism includes a second gear member, a drive link, and a follower link.      The second gear member is rotatably mounted on the upper strut member and is in meshing engagement with the first gear member so that the second gear member rotates when the strut is pivoted about the first gear member. The drive link has a fixed end fixed to the second gear member and a free end pivotally connected to one end of the follower link. The other end of the follower link is connected to the lower strut member. When the strut is pivoted from the lowered position to the raised position, the second gear member is caused to rotate, which pivots the drive link. Pivoting the drive link causes the follower link to extend the lower strut member out of the upper strut member.

Title: Breathing apparatus
Inventor: DEARMAN PETER T
IPC: A61M16/00
Filed: 1991-01-07
Granted: 1994-08-02
Abstract: A breathing apparatus is described for supplying pulses of a breathable gas to a patient; the apparatus comprises a gas inlet (10) connectable to a source of breathable gas, an outlet (37) connectable to provide gas to the patient, a gas flow passage (14, 15, 34, 36) extending between the inlet and the outlet, a main valve (16) located in the gas flow passage for interrupting the flow of gas to the outlet, a throttle (38) in the flow passage downstream of the main valve, a gas reservoir (42) and a valved duct (40, 44) connected to supply gas to the reservoir from the part of the flow passage between the main valve and the throttle; the main valve includes a piston (24) that is slidable within a cylinder (22) to open and close the gas flow passage, which piston is biassed in one direction by a resilient member (28) and biassed in the other direction by the gas pressure within the reservoir. When the main valve is open and gas flows from the source to the patient, gas leaks into the reservoir along valved duct (40, 44), thereby increasing the pressure in the reservoir (42); this continues until the pressure in the reservoir is sufficient to overcome the spring (28) when the piston moves to close off the gas flow passage. Gas can leak via the valved duct (40, 44) into the flow passage until the pressure in the reservoir falls to a level that allows the spring to move the piston to re-open the flow passage.
