Patent GB-2151308-A (GB)
Title: An engine having rotary speed control and emergency stopping apparatus
Inventor: ITO RYOICHI
IPC: F02D41/22
Filed: 1983-12-06
Abstract: The engine has a load detector and also detectors for sensing any abnormality of various factors influencing the normal engine operation. The rotary speed control circuitry 2 has an actuator 6 connected to a lever 54 which is also connected to the actuator 13 of the emergency stopping circuitry 3, the lever 54 being connected to a control lever 7 biassed by spring 39 into the engine stop position 10. When both actuators 6, 13 are deenergised the lever 7 is in position 10 as shown. When the actuator 13 alone is energised the lever 7 moves to a low-speed setting 9, and when both actuators 6, 13 are energised the lever 7 moves to a high-speed setting 8 for operating the engine under load. However if an engine abnormality (e.g. in oil pressure or water temperature) is sensed then the base of transistor 41 is earthed via sensor(s) 57,58 so that actuator 13 is deenergised and moreover the current flow to circuitry 2 via line 31 is cut off to also deenergise the actuator 6, whereby the lever 7 is moved to its stop position 10. The power supply to circuitry 2 via the circuitry 3 ensures that the engine is stopped also in the event of a defect occurring in the actual circuitry 3. <IMAGE>

Patent GB-2139624-A (GB)
Title: Process for recovering acetic acid
Inventor: KOGA KUNIO
IPC: C07C51/48
Filed: 1984-05-11
Abstract: Acetic acid is extracted from aqueous solution using an organic extractant comprising a tertiary amine/organic diluent mixture containing a proton-donating inorganic acid in an amount which is smaller than the number of moles of the tertiary amine and which is necessary to maintain the pH of the final-stage aqueous phase (raffinate) at below 4.0 and recovering the acetic acid from the extract. An example of the proton-donating inorganic acid is sulfuric acid. By means of this process, strict control of the neutralization of acids, conventionally carried out to prevent accumulation of the salts of the acids in the extractant, becomes unnecessary, and the recovery of acetic acid can be improved.

Title: A power assisted vehicle steering system
Inventor: ADAMS FREDERICK JOHN
IPC: B62D6/02
Filed: 1985-10-02
Abstract: A power assisted vehicle steering system has a rack and pinion steering gear 6 incorporating a servo motor 6a controlled by a valve 22. A fluid pressure supply line 3 to the valve 22 includes a throttle or regulating valve 5 which is adjustable by a stepping motor 30 that is speed responsive to increase incrementally the restriction by the valve 5 to fluid flow to the valve 22 as vehicle speed increases. A flow control valve 7 is responsive to fluid pressure in the line 3 upstream of the valve 5 and to fluid pressure in the line 3 downstream of the valve 5 so that a pressure differential across the valve 5 is sensed by spool 9 which is displaced to open the supply line 3 upstream of the valve 5 and a reservoir 1. This latter opening reduces the supply of pressure fluid available for actuating the servo motor 6a and the available power assistance as the vehicle speed increases. <IMAGE>

Patent GB-2192070-A (GB)
Title: Optical attenuator
Inventor: STAROMLYNSKA JACQELINE
IPC: G02F1/19
Filed: 1987-05-06
Abstract: An optical attenuator comprises an isosceles right triangular prism 62 having a part BDXY of one face ABCD adjacent the right angle apex CD metallised with silver or gold of layer thickness 46+/-5nm. Light 60 incident on the metal layer from within the prism 62 excites a surface plasmon for a narrow range of angles of incidence for a particular wavelength of light. The prism 62 is rotated about an axis through its centroid parallel to its apex CD to tune through one side of the plasmon resonance. This results in the phenomenon of attenuated total reflection in which energy is coupled from the light beam to the surface plasmon despite total internal reflection occurring. The light beam is accordingly attenuated to a degree varying with angle of incidence. The prism 62 may be accompanied by a retroreflector 64 arranged to return light from the prism 62 back to it for a second transit in the reverse direction. This nullifies the shift in beam direction associated with prism rotation. One or more additional reflectors (66, 78, 80) may be employed to render the output or attenuated beam parallel to or if necessary collinear with the input beam. <IMAGE>

Title: A method of jointing concrete floor slabs
Inventor: BROWN GEORGE CYRIL
IPC: E04F15/14
Filed: 1987-06-03
Abstract: A method of laying, jointing and controlling shrinkage in concrete ground floor slabs, comprising the steps of providing a sub-base in the form of hard core layer 17 having a large aggregate surface layer 18 which is capable of absorbing moisture and forming a mechanical anchorage for the concrete layer 19. A series of tie bars 21,22, together with the rough surface layer 18 serve to maintain the slabs in close relationship by preventing shrinkage. The absence of a slip membrane beneath the concrete permits free water within the latter to be absorbed downwardly as the concrete dries out resulting in a denser and more durable floor surface with substantially no gaps between adjacent slabs. <IMAGE>
