Title: Separating volatile materials
IPC: B01D7/02
Filed: 1979-06-06
Abstract: A crystallization process for in the vapor, the vapor then having separating a partially liquid mixture containing volatile components (A and B) forming a binary system in having a vapor pressure ratio A:B 0.1 to 10 at the B-triple point less than the ratio heat of sublimation to heat of melting of the B-component. The phase diagram has a B- enriched solid-vapor region above the three phase state temperature and a B-enriched solid/liquid region below such temperature. A first mixture of vapour and condensate are formed by vaporizing both components below the triple point, the first condensate comprising mother liquor and a B-enriched solid, the heat released being utilized to vaporize the components. A gas containing volatile and condensable components can be separated. Heat is removed to cause part of B to desublime, the A remaining in the vapor, the vapor then having heat removed therefrom while below the B-triple point to form a further condensate.

Title: Improvements Relating to Shearer Loaders
IPC: E21C35/23
Filed: 1979-12-06
Abstract: A shearer loader mining machine has shearer drums on pivoted support arms at each end of the machine. Each drum requires a ventilation supply, particularly at the end face adjacent the seam, to dissipate methane or other gas, and preferably also a water supply to trickle nozzles to lay dust. This machine has a duct (21) along each support arm (4) leading into a fixed tube (15) coaxial with the drum and delivering at the end remote from the arm. The drive means, generally reduction gearing (12), surrounds the tube within the drum. An injection nozzle (23) at the root of the arm induces air through an intake (22) just downstream and thus well clear of the dust-laden drum cutting zone and conveyor. The air stream may then be directed through a venturi (24) and before entry to the tube (15) be boosted by a further injection nozzle (53). The tube can also be used, in conjunction with further members (34, 38, 41), to convey water to the trickle nozzles. <IMAGE>

Title: Radar receivers
Inventor: LOEFFLER ALEXANDER
IPC: G01S7/28
Filed: 1981-05-08
Abstract: In a radar receiver with ECCM in the form of a side-lobe blanking system, i.e. where instantaneous level comparison is effected (19) between signals from a radar receiving channel 2-8 and signals from a blanking channel 10-16 of identical design but fed from an omnidirectional antenna (9), prior to the level comparison a separate doppler-frequency selective analysis 17, 18 is carried out in both the radar receiving channel and the blanking channel by use of a filter bank or a fast-Fourier processor for example. so that the signals from the radar receiving channel are only suppressed in those doppler frequency ranges in which signals of sufficient intensity are also received in the blanking channel. This avoids the disadvantage of known side-lobe blanking systems, in which the lobe width of the radar antenna (1) leads to substantial blind times in dependence upon interference levels from the side-lobes. <IMAGE>
Patent GB-2078349-A (GB)
Title: Control valve systems for gas water heaters
IPC: F23N5/02
Filed: 1981-06-09
Abstract: In a control valve system for a gas-fired, instantaneous water heater is disclosed, the valve 9 has a "snap" action constructed to inhibit the supply to the burner of insufficient amounts of gas to ensure reliable ignition. In one example, a flexible diaphragm 3 has opposite sides connected via respective passages to receive pressures upstream and downstream of a restriction in a water flow path. The diaphragm opens a gas valve in response to a predetermined flow of water along the path. In order to provide the "snap" action, a further passage is provided that links the two passages coupled to the diaphragm and contains a ball 22 that can block the further passage only when the water flow is sufficient to open the gas valve sufficiently for an ignitable quantity of gas to flow to the burner. Figures 2 and 3 (not shown) show additional valves thermostatically controlled in dependence on the temperature of the heat exchanger which control the pressure acting on diaphragm 3 and hence the opening of valve 9. <IMAGE>

Title: Treating the thatched roof of a building with a protective fluid
Inventor: LINNEY ANDREW WILLIAM
IPC: E04D9/00
Filed: 1981-07-24
Abstract: A thatched roof T is treated with fluid by first shrouding the thatch in a relatively lightweight cover A, spraying the thatch, under the cover, preferably from above and beneath, with pressurised fluid to penetrate beyond the upper (or lower) surface envelope of the thatch but not so pressurised as to cause the fluid to dislodge any thatch and finally removing the cover to expose the thatch.
