Title: Forming a Metal or Metal Compound Coating on Thermally Homogenised Glass
IPC: C03C17/00
Filed: 1981-06-17
Abstract: In order to control the thickness of a metal or metal compound coating which is formed on a face of a freshly formed ribbon of hot glass by contacting with fluid medium(s) comprising substance(s) from which the coating is formed, the glass is first thermally conditioned (e.g. selectively or differentially heated) to eliminate or reduce temperature gradients across the ribbon width to be coated. The thermal conditioning may be controlled automatically in dependence on signals from a coating thickness sensor. Heaters 14, 15 (or streams of hot gas) in thermal conditioning compartment 11 selectively heat the outer portions of glass ribbon 4 to compensate for their relative coolness. Transversely reciprocating spray gun 7 than applies coating solution; alternatively, a conduit supplies a gas stream containing vaporised coating precursor. <IMAGE>

Title: Hand operated teaseling device
Inventor: HAIGH JOHN STEPHEN
IPC: D06C11/00
Filed: 1981-10-03
Abstract: A portable raising device for producing a napped effect on the surface of a fabric comprises a housing 2 with an aperture (3) and one or more teasels 5 mounted for rotation on a first axis or axes 11 and about a second axis 6. The first and second axes 11, 6 are skewed with respect to one another such that on driving, e.g. by a hand-held electric drill, the teasel or teasels about the second axis 6 successive axial portions of the working surface of the or each teasel project through the aperture sequentially. The teasels are mounted in an adjustable relationship with the aperture in the housing so that the degree to which the teasels protrude therefrom can be predetermined. Each teasel is subjected to frictional braking by action of a spring 10 against a braking disc 14. <IMAGE>

Abstract: Pearl polymerizates are produced by radical polymerization of vinyl chloride and monomer mixtures in an aqueous medium by use of water soluble initiators without suspension stabilizers and emulsifiers. Initial polymerization mixture may be dissolved in specific organic solvents and VC may be replenished during reaction. The VC polymers obtained are pearl-shaped VC polymerizates of uniform particle size, high porosity, fluid stable and shape- retentive under heat.
Patent GB-2096280-A (GB)
Title: Safety relief of valve cavity pressure in the event of fire
IPC: F16K24/02
Filed: 1982-02-12
Abstract: The housing (12) of a valve is internally provided with a valve cavity- to-throughbore bypass conduit (62) on its upstream side. A relatively vulnerably-placed body (134) of heat- activated material normally forces a bypass valve (93) to close this conduit. In the event of a fire in the vicinity of the protected valve, the heat-activated body (134) loses its forcing capability and the bypass valve (93) opens, moving off a first metal- to-metal seat (78) and making a second metal-to-metal back seat (98). Any fluid that had previously leaked from the throughbore (14) of the protected valve into the valve cavity (23) may then pass to the upstream side of the protected valve, instead of becoming dangerously highly pressurized in the valve cavity. <IMAGE>

Inventor: HERD DAVID P
IPC: F16J15/24
Filed: 1982-07-29
Abstract: A stem sealing means for high pressure, balanced, rising stem gate valve includes at least one seal set 119, 121 at each of the actuator and balance stems 51. Each seal set 119, 121 comprises a pair of frustoconical metal ring gaskets 131 between and in contact with which are two make-up rings 133 of compliant, tough material of high lubricity, e.g. tetrafluoroethylene polymer.

Around the inner periphery of the core ring adjacent the respective actuator or balance stem 51 is disposed a bearing ring 137 of material like that used for the make-up rings. The seal set is compressed by a packing retainer 67 such that the metal gaskets are coined into metal-to metal sealing engagement with the stems 51 and adjacent valve body parts. The sandwich stack, consisting of the core ring and bearing ring disposed between the make-up rings, is deformed to conform to the shape of, and fills substantially all of the space between, the compressed metal ring gaskets. The volume of the core ring is approximately one- third of the total volume of the sandwich stack. <IMAGE>

Title: Removing carbon monoxide from air
Inventor: BILLIET COLIN
IPC: B01D53/86
Filed: 1982-09-02
Abstract: Apparatus for treating a supply of compressed air containing carbon monoxide but substantially devoid of free water and of relative humidity sufficient for comfortable breathing, to render it suitable for breathing purposes, comprises a pressure vessel (21) having a heater (39) at its inlet to which the air is supplied without any drying treatment. From the heater the air passes to and through a bed of granular catalyst material within 31 in the pressure vessel, the catalyst oxidising CO in the air to CO2. A temperature sensor (37) within or immediately downstream of the catalyst bed controls the heater to maintain a mean bed temperature of not less than 100 DEG C during air passage therethrough, so effecting a phase change in the water vapour in the air to avoid poisoning of the catalyst. The air passing from the bed is delivered cooled, but not further treated for breathing purposes. <IMAGE>

Title: Improved nebuliser
Inventor: DYSON ANTHONY JOHN
IPC: A61M11/06
Filed: 1983-12-08
Abstract: A nebuliser for administering bronchodilators, etc., comprises a horizontal cylindrical casing (50) containing active solution (70). Air or gas is supplied through an inlet (56) to a venturi (54) such that solution is drawn up a capillary channel (68) to be entrained in the air stream. From this main chamber the flow enters a subsidiary chamber having peripheral apertures (80). Air is drawn into the subsidiary chamber to dilute and entrain the aerosol flow from the main chamber. The proximity of the aerosol chamber to the patient's mouth means that dead space is kept to a minimum. The supply of solution (70) can be continuously maintained through an inlet (90), to permit continuous nebulisation. The unit comprises a mouthpiece (96) and support (98) resting on the patient's chin such that the unit can be continuously supported on a patient's face. <IMAGE>

Title: Passive sonar systems
Inventor: ZIEGENBEIN JOCHEN
IPC: G01S11/14
Filed: 1984-03-21
Abstract: To estimate parameters such as range, speed, course and/or transmission frequency of a moving target S radiating acoustic pulses into the water, from a receiver E remote from the target, echoes received in an off-target direction I by reflections from discontinuities SC, SC2 in the sea are monitored. Each discontinuity in the direction I will reflect a pulse transmitted by the target S with a different Doppler shift, varying as a function of the bearing of the discontinuity relative to the target. The frequency-time characteristic of the total acoustic radiation received from the direction I is determined, and it is shown that the required parameters can then be deduced by curve-fitting techniques. It is further shown that if acoustic radiation from three directions is monitored, are on-target and two off-target, some of the parameters can be calculated directly from the three frequency-time characteristics, without resort to curve-fitting. <IMAGE>

Title: Heat exchanger
Inventor: OSCARSSON ROLF ARNE
IPC: A61M1/36
Filed: 1985-04-15
Abstract: The present invention relates to a heat exchanger which is specifically adapted for use in connection with blood oxygenators, particularly bubble oxygenators. The core of the heat exchanger is generally cylindrical and closed at both ends. The cylinder is made of thin walled material with good heat exchange properties such as aluminum. The portion of the heat exchanger core which will be exposed to blood is coated with a biocompatible material such as tetrafluoroethylene. The heat exchanger may be connected to a source of heat exchange medium, such as water, through couplings in the top portion of the heat exchanger core. The heat exchange medium is then circulated through the core providing heating or cooling which is capable of heating or cooling blood within a bubble oxygenator. The heat exchanger core is then nested within a suitable receiver. The inner walls of said receiver may be reticulated in order to facilitate exchange of heat between the heat exchanger core and a fluid, such as blood, flowing between the outer wall of the heat exchanger core and the inner wall of the shell.
