Title: Regenerator control by flue recirculation
Inventor: TODD JULIAN BRANFORD
IPC: F23N5/18
Filed: 1986-04-15
Abstract: The high fuel economy inherent in heating systems incorporating static-bed thermal regeneration can be made available to processes requiring precise temperature control by coupling the air supply 7 and the flue extract 9 together in a circuit 24 external to the regenerator system. A control unit 21 monitors the mass flow rate through valves 3, 11, 16, 19 and the fuel valve 20, and alters their settings periodically so as to maintain a substantially constant fluid mass flow in the circuit 24. The thermal output of the regenerator system may therefore be modulated without risking disruption of the heat store temperature profiles and the consequent unpredictable heating behaviour. The internal temperature of the enclosure is monitored by a temperature transducer 25, enabling the control unit 21 to be programmed to produce any temperature/time profile required by the process. <IMAGE>

Patent GB-871465-A (GB)
Abstract: 871,465. Surveying instruments. MAGYAR OPTIKAI MUVEK. Sept. 22, 1958 [Sept. 24, 1957], No. 30163/58. Class 97(2) A tacheometer, Fig. 11, comprising a telescope having an objective lens 9 and focusing lens 10, has a glass diaphragm 2 coaxial with the optic axis 1 and rotated in accordance with the angle of elevation so that by reading, through an eyepiece 6, marks on the diaphragm 2 in conjunction with an image of a stadia rod, the height and distance of the stadia rod from the horizontal trunnions of the tacheometer may be directly determined. A level, not shown, is connected by bolts 24, 25 with a friction disc 4, contacting a wheel 3 which is connected by means of glass ring 23, and mount 22, to the diaphragm 2. By pushing a button 15 inwardly a wedge 12 is moved so that the focusing plane is moved away from the lines on the diaphragm 2 on to the collimating plate 14 provided with line h, Fig. 10. By rotating a knob 16, between limits set by arm 17 and stops 18, 19, Fig. 13, a prism 11 is turned from the position of Fig. 11 to that of Fig. 12, where the rays pass through a part of diaphragm 2 nearer to its centre and having a different set of markings, the observation being made through eyepiece 7. A third eyepiece 5, is for reading the azimuth and elevation circles. To measure distances or heights the inverted image of the stadia rod is aligned with a vertical collimating line v or v<SP>1</SP> respectively and the intercept on the rod made by two divisions spaced a certain distance apart, such as six divisions, is multiplied by a fixed constant, such as 100. Corrections to be applied for the elevation are readily indicated and the Specification sets out the theory of the instrument. A suitable stadia rod, Fig. 14, has an indicating line 1, of variable width by forming it as a white background between two black plates 11, 12, mounted as a parallelogram linkage and moved by knob 10 which rotates a rod and a lever 16 whose free end engages a vertical slot 15 in plate 11. By rotating crank 5 the threaded nuts 6, 7, carrying plates 11, 12 and pointer 3, respectively, travel in opposite directions along the threaded spindles 8, 9, the pointer 3 being arranged to travel 10 times the distance of plates 11, 12. Since slot 15 is parallel to spindles 8, 9, vertical displacement of plates 11, 12, does not affect their distance apart. In a modification the pointer 3 is connected by rack and pinion to crank 5 and the latter has a threaded shaft which axially moves a non-rotatable nut thereon to rock a bell crank lever and thus vertically slide a rod whose upper end is connected to the plates 11, 12. The width apart of plates 11, 12 is varied by rotating the vertical rod.

Patent GB-874177-A (GB)
Abstract: 874,177. Selsyns. FERRANTI Ltd. March 12, 1959 [March 15, 1958], No. 8367/58. Class 35. [Also in Group XXXVIII] In a transducer for measuring angular rotation comprising a four-pole stator 11 and a four-pole rotor 16, the stator poles 12a &c. being symmetrically offset with respect to the rotor poles 17a &c. so that with angular rotation each pair of opposite airgaps 18a, 18c and 18b, 18d remain equal in their pairs, but vary in opposite sense from the other pair, whereby the angular movement may be determined by the unbalance of a bridge comprising a winding 15a &c. on each stator pole 12a &c., there are additional windings 21a &c. on the stator cores 12a &c. interconnected to maintain equality between the fluxes in the air gaps of each pair, with radial displacement of the rotor. Windings 21a, 21c of one pair are connected in series opposition with a capacitor 22ac. Any component of displacement of the rotor 16 along the axis of this pair of windings unbalances the air gaps 18a, 18c to produce an error voltage in the circuit including windings 21a, 21c, the direction of the current so produced being such as to restore equality between the fluxes in the air gaps 18a, 18c. The capacitor 22ac is tuned with the coils to the supply frequency to increase the sensitivity of the arrangement. Coils 21b, 21d produce a similar effect for components of displacement of the rotor along the perpendicular axis. Specification 874,176 is referred to.

Title: Cigarette filters
Inventor: BASSETT DAVID WYN
IPC: A24D3/04
Filed: 1989-04-21
Abstract: The invention is concerned with the problem of improving the efficiency of cigarette filters so that the total particular material per puff delivered to the smoker is as near as possible constant during the smoking of the cigarette. To overcome disadvantages of earlier proposals, the filter 14 is provided with a preferably conical chamber extending axially into the plug, the wall 20 of the chamber being impermeable to smoke and provided with flow-through apertures or slits 26 opening into the filter plug and extending longitudinally of the chamber whereby in use smoke drawn from the rod into the chamber passes into the filter material so that the flow-through apertures or slits become progressively blocked with solid material from the mouth end towards the rod end of the filter as the rod is smoked thereby increasing the path length of the smoke within the filter during the smoking of the rod. The density of the filter material increases along its length from the mouth end to the smoking material end to further flatten the natural yield profile of the cigarette. <IMAGE>
