Patent GB-2087732-A (GB)
Title: Valves
IPC: A62B9/02
Filed: 1981-11-18
Abstract: A valve, notably for use as a demand valve in breathing apparatus, has a pressure-responsive diaphragm (28) coupled to one arm (18) of a two-armed spring member (19), which lies in the path of a jet of gas which vents from a control chamber (14) through an orifice (17), gas being continuously supplied to the control chamber via another orifice (15). Deflection of the diaphragm in response to pressure changes in the outlet chamber (3) caused by inhalation and exhalation pivots the arm (18) towards or away from the orifice (17) to control the rate of venting from the control chamber and thereby vary the pressure within the control chamber. The setting of the arm (18) in relation to the orifice (17) is adjustable by means of a spindle (21) which applies a variable clamping force to the other arm (20) of the spring member (19); flexure of this arm (20) shifts the spring member in the corner (22) into which it is pressed at the junction between its two arms (18, 20). Modifications of the variable clamping means are described with respect to Figs. 3 and 4, (not shown). Spec. No., 2,054,207 A and 2,076,661 A are referred to. <IMAGE>

Title: Automatic slack adjuster mechanisms
IPC: F16D65/60
Filed: 1981-11-27
Abstract: The mechanism has input and output members 1, 4 each pivotable about a common axis to apply and release a brake-applying force; a force-transmitting member 5 is threadedly engaged with the output member 4 and is releasably clutched via clutch faces 6, 7 to the input member 1. To effect slack adjustment, the mechanism includes brake-clearance determining means having a stepless multiplate clutch 10 which is released upon pivotal movement of the input member in a brake-force applying direction, equating with the required brake-clearance to allow the clutch to slip during movement of the input and output members corresponding to excessive clearance. Upon the return stroke, the clutch is re-engaged so that pivotal return movement of the output member is limited by the brake-clearance determining means whilst the input member is allowed fully to return to its initial position. The determining means may utilize members 11, 21, 23, as shown; an alternative arrangement is disclosed. The mechanism may have a reset mechanism and wear indicator lever 27 carried by a cam plate device 28. <IMAGE>

Title: Improvements in or relating to electrical plugs
Inventor: CAMMISS DAVID
IPC: H01R13/707
Filed: 1984-10-12
Abstract: An electrical plug and socket arrangement comprises a plug (10) with two or more pins (18, 20) and a cooperating sockets (12), with apertures (26) for receiving the pins, wherein at least one of the pins (18) of the plug includes a recessed region (22) for receiving a cooperating member (36) associated with the power supply switching mechanism of the socket, the arrangement being such that power can only be supplied to the plug when the plug is fully engaged in the socket and the member is engaged in the recess. Because power can only be supplied to the plug when the plug is fully engaged in the socket and when the member is engaged in the recess, the switching arrangement effectively acts to lock and retain the plug in the socket while the power is on. This means that a live plug cannot be removed from the socket, eliminating the risk of electrocution by touching exposed live pins. <IMAGE>

Title: Improved method of culturing cells
Inventor: RUPP RANDALL G
IPC: C12P21/08
Filed: 1985-02-08
Abstract: A method of growing fragile cells, i.e., cells having no cell membrane such as animal cells or genetically modified animal cells, to high density in culture comprises the steps of suspending permeable microcapsules containing a seed culture of such cells in a medium, directly sparging a gas through the medium along the capsules, and allowing the cells to grow. The gas comprises a gas or a selected mixture of gases and is sparged at a rate high enough to attain a substantial partial pressure equilibrium between the gas and liquid phase. The partial pressure of gases essential for cell growth and normal rates of cell mitosis can be maintained in the medium by controlling the composition of the gas and maintaining a threshold sparging level. By sparging, oxygen availability need no longer be a growth-rate limiting factor, and cell densities on the order of 10<8> cells/ml may be achieved.
