Title: Ventilation device for an ostomy bag
Inventor: MADSEN POUL
IPC: A61F5/44
Filed: 1982-10-08
Abstract: An ostomy bag for the collection of drainage substances from an opening in the abdomen, caused by a surgical operation, may be supplied with an excess-pressure valve, which consists of a valve housing (3) fastened to the wall of the bag (1) and with an inlet opening (4) for the gases from the interior of the bag as well as a vent hole (6). Inside the housing there is a vent seat (10) running round the opening (4). Against this seat (10) a disc-shaped vent body (8) is continuously pressed by means of a number of elastic flaps (7) to allow an outlet through the vent of any excess-pressure in the bag. In this way the pressure in the bag can be regulated, and a suitable back-pressure for the intestinal function achieved, securing a closing of the outlet opening when the valve is in its closed position. This means that no leaking out of fluid can take place. In order to deodorize the gases a carbon filter can be mounted round the outlet opening, which filter the gases must pass.

Patent GB-2161266-A (GB)
Title: Switch device
Inventor: IOANNIDES ANTONIS CHRIS
IPC: H03K17/969
Filed: 1985-06-19
Abstract: A switch device mounts a radiation source 7 and a radiation sensor 9 so that when the device is placed against a screen 12 transparent to the radiation the presence or absence of a finger F or other operating element at a predetermined location on the other side of the screen determines whether or not the sensor 9 receives sufficient radiation to provide an electrical output. The finger or operating element may itself create the path for the radiation between the source and the sensor directly or it may move a reflective element (Fig 3) to create or destroy such path. Fixed reflective elements on the other side of the screen (Fig 4) may provide a portion of a radiation path which can be interrupted by the finger or operating element; and an array of such path portions may be provided and the associated sensors repetitively scanned so that a symbol traced within the array can be recognised. <IMAGE>

Title: Checking voltages in integrated circuit by means of an electron detector
Inventor: GARTH SIMON
IPC: H01J37/244
Filed: 1985-11-05
Abstract: The voltage at a part of an integrated circuit 4 may be ascertained by an electron detector which analyses the secondary electrons emitted from the integrated circuit as a result of bombardment by an electron beam. A magnetic field which weakens as distance from the circuit increases causes the secondary electrons to follow helical paths of increasing pitch to a region where they are substantially parallel to a given direction 2 and have speeds substantially equal to those fat which they left the surface of the integrated circuit. An inclined, retarding electrostatic field 17 deflects the secondary electrons to different electron responsive means, e.g. scintillators 18 depending on their different electron energies. A histogram of electron energies may be produced for comparison with expected energy distributions to provide an accurate indication of the potential of the bombarded part of the integral circuit. <IMAGE>

Title: Determining the porosity of geological formations
Inventor: FONTENOT JOHN E
IPC: G01V5/10
Filed: 1986-12-04
Abstract: A downhole measurement-while- drilling neutron porosity measurement device comprising a neutron source 22 and detector 24 is used the determine the true formation porosity of strata. An initial measurement is taken shortly after the formation is bored and before any substantial invasion by the drilling fluid occurs. Subsequent measurements are made until a steady measurement is reached indicating saturation of the formation by the drilling fluid to the depth of the measurements. The difference between the initial and steady measurements is indicative of the true porosity of a gas containing formation. Corrections may be made for natural background gamma -radiation. A resistivity plot may be performed to check that invasion is complete. <IMAGE>

IPC: F01D11/10
Filed: 1989-03-31
Abstract: The instantaneous clearance between a turbine casing and a turbine rotor is calculated according to measurements of selected engine operating characteristics such as temperature, pressure and rotational speed. In an embodiment of the invention, the computed instantaneous clearance is used to control cooling air which is bled from the fan and ducted onto the casing, in order to attain a desired clearance. …<??>Mathematical modelling of component behaviour is used, including infering the instantaneous temperature of the component from the time-behaviour of a predicted steady state temperature (SSTemp). …<??>Changes in SSTemp are caused by changes in the present operating conditions, which occur during engine acceleration and deceleration. The instantaneous temperatures indicate the diameters of the casing and the rotor, and thus the instantaneous clearance between them. …<IMAGE>…

Title: Ice release surfaces
Inventor: ANDREWS EDGAR HAROLD
IPC: C09K3/18
Filed: 1988-04-14
Abstract: An ice release system comprises a substrate and an ice release coating on said substrate, said system remaining effective for multiple ice release events. The coating comprises a two component polymeric mixture. The first component of the coating is so firmly bonded to the substrate that it cannot be completely removed with a solvent and the second component is substantially completely compatible with the polymeric material of the first component and is homogenously dissolved or dispersed therein. The second component is substantially unbonded to the substrate, is not water leachable, has a glass transition temperature (Tg) less than 0 DEG C and is sufficiently viscous that the second component will not exhibit substantial flow from the mixture over a vertically arranged coated substrate. In an ice release event a surface portion of the second component is removed with the ice, whereafter migration of the second component in the mixture re-establishes homogeneity to form a new surface portion of the second component.
