Title: Automatic readjusting mechanism for servo brakes
IPC: F16D65/46
Filed: 1979-05-31
Abstract: An automatic adjustment mechanism for servo-brakes has elements (14', 12', 11, 12, 14) for transmitting thrust between brake shoes and in response to excessive movement in either direction a nut (12 or 12') is rotated on a screw (14 or 14') by a ratchet tooth system (15 or 15') to extend the mechanism. To render the adjustment independent of the direction one of two rings (19 and 19'), say 19, is in one direction carried with a sleeve (11), but the other ring 19' is stopped by an abutment (21') on the housing (10). A pin (24) on the ring (19') penetrates a slot (25') in the sleeve (11) and a slot (27') in a ring (15') which forms part of the ratchet tooth system one slot being axial and the other being oblique. When the ring (19') is stopped by the abutment (21') on the housing (10) the ring (15') is rotated by the pin (24') and when the sleeve (11) returns nut (12') is rotated by ring (15'). A manually operated readjusting mechanism includes a shaft (32), gear wheel (33) crown wheel (22) to rotate the sleeve (11). <IMAGE>

Title: Dual flush cisterns
IPC: E03D1/14
Filed: 1979-07-26
Abstract: A dual flush siphon for a W.C. cistern has, around the plunger stem 20, air ports 46 which can be covered or uncovered by a ported rotary valve member 42-44 mounted on a boss 26 on the siphon bell 22. Hence the installer of the siphon can select whether the siphon is to be used as a dual flush siphon or not. When in use as a dual flush cistern the lower ends of the air ports are closable conventionally by a washer 52 on the stem 20 so that holding the plunger raised produces a full flush whereas releasing it (assisted by a release spring 54) admits air to break the siphon and produce a partial flush. <IMAGE>

Title: Purification of gas for the production of methanol by synthesis
IPC: C10K3/04
Filed: 1980-02-25
Abstract: Crude gas mainly consisting of hydrogen and carbon monoxide and deriving from the gasification of coal or crude oil fractions, is cooled under 0 DEG C, and methanol is injected to remove water and other condensable components from the crude gas, whereafter the gas, after further cooling, is scrubbed by m-xylene at 25 ata to 100 ata and at -5 DEG C and -35 DEG C so that in the scrubber all sulphur compounds are removed. A minor part of the sulphur-free gas is treated in a CO-conversion plant, in which the carbon monoxide and water are converted to H2 and CO2 and scrubbed with methanol to reduce the CO2 content in the gas to ca. 2%. The resulting converted and methanol- scrubbed gas is then mixed with the main gas stream, which does not flow through the CO-conversion plant, to form the synthesis gas having a ratio H2 : CO=2 : 1 and a CO2 content of about 5%.

Title: Dampening Device for a Printing Machine
IPC: B41F7/24
Filed: 1980-03-03
Abstract: A dampening device for an offset rotary printing machine comprises a fountain roller (1) rotating at a first surface speed and an inking roller (4) rotating at a second surface speed.

Patent GB-2049148-A (GB)
Title: Heat exchanger tube support
IPC: F22B1/18
Filed: 1980-04-11
Abstract: In a counterflow non-contact heat exchanger, tube bundles carry fluid back and forth across a hot gas path. As the fluid in the tubes flows vertically downward the temperature of the fluid rises. As the gas rises in the heat exchanger it loses heat due to the heat exchange process. This means that the temperature profile of a tube bundle will show a greater thermal expansion in the lower tubes. The present invention seeks to provide an efficient and improved support arrangement for heat exchanger tubes to accommodate this phenomenon by supplying a pivotally mounted tube support plate which will rotate and translate slightly from a substantially vertical plane to accommodate thermal expansion. Further, if there are multiple tube bundles, additional tube support plate sections will allow a tube support plate to articulate in sections to accommodate thermal movement.

The arrangement is such that when wheels (14) are in their fully raised position, brush (22) contacts the surface being cleaned, and when wheels (14) are in their fully lowered position, brush (22) does not contact the surface being cleaned. The latter occurs when the flap is moved to a position to open suction intake (32) for connection of a nozzle/hose assembly thereto. <IMAGE>

Title: Improvements in or relating to propeller-driven water-borne craft
IPC: B60V1/14
Filed: 1980-12-31
Abstract: A propeller-driven water-borne craft 1, particularly a sidewall-ACV, has the shafts 20 on which the propellers 5 are mounted inclined to the horizontal by a substantial amount. (8 DEG  to 20 DEG ). To reduce propeller boss cavitation due to a local high velocity caused by high craft speed and/or high shaft speed, which condition is particularly exaggerated by the shaft inclination where the incident flow relative to any point on the propeller boss alternates rapidly in direction as the shaft rotates, pressurised air is discharged in the proximity of the propeller boss 5. The air is discharged at the outlet ends of conduits 31 attached to the "trailing" edges of the shaft- supporting brackets 21 by clips 40. <IMAGE>

Title: Intake gas recirculation
IPC: F02B11/02
Filed: 1980-09-05
Abstract: The present invention refers to the adapting of an internal combustion spark ignition engine to a multifuel engine having maximum thermodynamic efficiency possible with each particular fuel. The innovation consists in the variation of an effective compression ratio of the engine by recirculation of unburned gases from the cylinder to the intake tube (9) of the engine in a certain extent of the compression stroke of the engine. The recirculation of the intake gases is controlled by an actuating device (5) with variable action. The basic effect of the invention is to confer to the engine the property of having a variable effective compression ratio optimized for a particular fuel and at the same time to use a large expansion ratio, being constant and independent of the compression ratio, in order to obtain a high thermodynamic efficiency and a low specific fuel consumption. The invention can be applied on existing engines or on new engines in order to get a highly efficient use of volatile or gaseous fuels, such as some petroleum derivates and its alternative fuels like the alcohols and biogases.
