Patent GB-2077885-A (GB)
Title: Governor for regulating and controlling gas pressure
IPC: G05D16/06
Filed: 1980-06-18
Abstract: A gas pressure governor comprises a hollow body having an inlet 3 and an outlet 5 separated by a partition 4 mounting a port sleeve 6 having a valve seat in the form of an annular lip seal 10. A poppet valve has a head 9 and two opposed stems 12 and 15. A compensating diaphragm 13 is mounted on the stem 12 and a main diaphragm 16 is mounted on the stem 15. The main diaphragm 16 in conjunction with the partition 4 provides an outlet chamber 23, and the compensating diaphragm 13 with the port sleeve 6 and partition 4 provides an inlet chamber 26. A passageway 24 extends through the valve stems. A spring 20 which can be adjusted applies a force to the valve stem. In operation, the valve is subject to the spring force and is moved axially relative to the valve seat by the compensating diaphragm in response to inlet pressure variations upstream of the valve, and moved by the main diaphragm in response to variations in pressure downstream of the valve whereby the valve is closed on the seating when pressure on the main diaphragm exceeds the control force applied by the spring means. <IMAGE>

Title: Recovery of liquid sulphur trioxide
IPC: C01B17/90
Filed: 1980-06-27
Abstract: Sulphur trioxide is recovered in liquid form by condensation from a gas containing sulphur trioxide. The gas is cooled to a temperature from 26.7 DEG C. to 32 DEG C. (80 DEG F. to 90 DEG F.) and continually introduced into a condenser whereby sulphur trioxide is condensed and continuously removed from the condenser surfaces as it condenses. The condensed sulphur trioxide is continuously removed from the condenser and melted to produce liquid sulphur trioxide. The process is particularly suitable for condensing sulphur trioxide from a gas containing relatively low concentrations thereof. It obviates the conventional step of absorbing the sulphur trioxide in sulphuric acid and distilling the resulting oleum and condensing the vapours of such distillation.

Patent GB-2083921-A (GB)
Title: Optical Fibres
IPC: G02B6/028
Filed: 1980-09-09
Abstract: One of the hazards to which optical fibres may be subjected is that of irradiation by ionizing radiation of neutrons, which causes undesirable increases in attenuation. Evidence in the literature indicates the only prospects of achieving radiation hardness, i.e. reduced susceptibility to radiation, was to use pure silica, which has certain demerits. However, we have found that a graded refractive index multi-mode optical fibre with a core of a binary SiO2/GeO2 glass and a cladding of a binary SiO2/B2O3 glass, made by an internal vapour deposition technique has improved radiation resistance characteristics.

Title: Improvements in vehicle exhaust pipe protection
Inventor: SUMNER JOHN EDWARD
IPC: F01N13/16
Filed: 1981-07-02
Abstract: The present specification provides a binding tape for use in protecting vehicle exhaust pipes. The tape comprises a laminate formed from at least one metallic foil and a layer of a dry adhesive plastics material. By applying the dry adhesive layer to the outside of an exhaust pipe, the heat of the exhaust causes the dry adhesive plastic layer to adhere to and set against the exhaust. The metallic foil, preferably aluminium, then protects the exhaust from the elements.

Title: Echo sounder transducer
Inventor: TOUBKIN WALTER MILTON
IPC: G10K11/02
Filed: 1982-04-08
Abstract: Ease of manufacture, reduced susceptibility to damage by mechanical shock and improved isolation from spurious mechanical impulses are provided by securing a transducer element to a rubber-type coupling element which is secured to the transducer casing. The coupling element can be a disc formed of natural of synthetic rubber and the use of neoprene is specifically disclosed. Once the transducer element is secured to the coupling element which is secured to the casing, a simple test can be undertaken to monitor the amplitude of energy transfer between the transducer element and the casing. This test is conducted before the transducer manufacturing process is complete and consequently it is possible to dismantle a defective product at a sufficiently early stage to enable some of the components to be re-used.

Title: Out of proximity alarm system
Inventor: SINGH KUNWAR CHANDER JEET
IPC: G08B21/24
Filed: 1982-09-01
Abstract: An out of proximity alarm system useful for indicating when the distance between two bodies has increased beyond a predetermined distance is disclosed. In the preferred embodiment, the system comprises a radio transmitter 500 attachable to one of the bodies, such as a personal article such as a briefcase and having a pulsed R.F. output. A radio receiver 600 carried by a second body, such as a person, receives the transmitted signal when the two bodies are within range of each other. The receiver incorporates a time delay stage 660 which is kept disabled by the received pulsed signal. Should the distance between the two bodies increase beyond a predetermined amount the pulsed signal will have insufficient strength to keep the time delay stage disabled, thus activating an alarm 690 and alerting the carrier of the receiver that he has left the personal article behind. Other embodiments utilise transponders, or ultrasonic or infra-red radiation, or the variation of capacitance with separation distance. <IMAGE>

Title: Duplex printing system
Inventor: BOBICK THOMAS WALTER
IPC: B41J3/60
Filed: 1982-10-01
Abstract: A printing system for duplex printing a plurality of document page images on a plurality of sheets from a supply station (16) includes memory means (10) for storing print control information which defines the document images. A printer (12) prints the page images on sheets as they are transported past a print station (14) by a vacuum belt transport arrangement (28) defining a closed sheet path. The sheet path is of sufficient length such that a number of sheets are transported simultaneously therethrough. A sheet inverter (40) receives sheets sequentially from the sheet path after the sheets are printed on their first sides and returns them to the sheet path (28) in an inverted orientation prior to printing on the second sides of the sheets. A gate (46) selectively diverts the sheets, after duplex or simplex printing, to an output stack (54). The system makes maximum use of the print capabilities of the printer and maximises the number of sheets which can be printed on both sides in a given period of time. <IMAGE>
