Title: Method of and means for heat transfer
Inventor: BOOTH GEORGE RONALD
IPC: F24D11/00
Filed: 1984-01-25
Abstract: A method of and apparatus for transfer of heat e.g. from atmospheric air for heating the interior of a house or other building or more than one such building comprises passageway means shown as a collector pipe (1) having a restricted air inlet (2) and an outlet (4) which latter is connected to a pump (5) for drawing air through the collector pipe (1) from the restricted inlet (2). Resulting expansion of the air as it is drawn through the collector pipe (1) causes it to take up heat from the wall of the latter which in turn takes up beat from the atmospheric air or other media with which it is in contact. The heated air is then supplied by the pump (5) through pipework (3, 30) for distribution within the house. The collector pipe (1) may be conveniently accommodated in the loft of a house and the apparatus may also provide water heating. The operation of the apparatus may be also augmented by reclamation of heat from heated domestic or similar waste water. <IMAGE>
Patent GB-2138102-A (GB)
Title: Control of pneumatic spring supporting vehicle seat
Inventor: MISCHER HANS-PETER
IPC: B60N2/90
Filed: 1984-04-04
Abstract: Sensing means 4, 5 are located at positions above and below a rated central position of the seat and are actuated (by magnet 6) according to movements of the seat from the central position. Upon actuation, the sensing means 4, 5 provide signals for a differential "counter" 7 which when an upper or lower limiting value is reached automatically resets itself to a starting value between the two limiting values and emits an appropriate control signal to operate an air valve 11 to either supply air to or discharge air from the pneumatic spring (15).   Dynamic oscillations of the seat about the central position cancel out in the counter. This ensures that the air valve 11 is not operated unnecessarily. The counter may be a digital counter, but is preferably a capacitor which is charged by one of the sensing means and discharged by the other. <IMAGE>

Patent GB-2145763-A (GB)
Title: Locks
Inventor: ROBINSON WILLIAM KEITH
IPC: E05B13/10
Filed: 1984-08-23
Abstract: The deadbolt 2 of a rim lock can normally be withdrawn from the inside by turning the knob 7. By key-operation of a cylinder 43 carried within the knob, however, the knob can be locked from the inside to prevent potential intrusion by a burglar breaking out glass from an adjacent window or glazed door for example, and reaching in to turn the knob. The knob is journalled in the lockcase 1 with a limited degree of axial freedom. In its normal axial position shown in Fig. 9 the knob turns freely and is located axially by a radial tongue 50 running between a shoulder 53 of the lockcase and a retaining plate 23. When the key is inserted to turn the cylinder plug 43 within the knob, the tongue 50 is withdrawn by an eccentric peg 48 on the rear of the plug 43. The knob can now be pushed in as a whole against the action of a return spring 57, so that projections 54 on the knob engage in recesses 56 in a surrounding skirt 55 of the lockcase to securely resist turning of the knob. Turning back the cylinder plug 43 within the knob while the knob is pressed in projects the tongue 53 behind the plate 23 in the lockcase to retain the knob in its locked position. Any forcing torque applied to the knob is now resisted by the robust formations 54/56 without putting any load upon the tongue 50. <IMAGE>

Title: Method of reducing the dependence of the air gap energy on gap length in a magnetic circuit and apparatus using the method
Inventor: WITSCHI MARTIN
IPC: H01F7/10
Filed: 1985-03-20
Abstract: To reduce the dependence of sir gap energy changes in a magnetic circuit (13, 23) with an air gap, the magnet or induction field (H) is refracted at the marginal areas of the air gap in order to change its alignment in the air gap. This is achieved by an oblique positioning of the marginal areas of the air gap defining poles (A, B, A'), for example by designing them with teeth (21, 25). In this way a pronounced independence of the energy change in the air gap per sir gap width change is achieved, so that the magnetic device can be used independently of the air gap width at the moment, for example as a force generator which may include an armature. <IMAGE>

Title: Cyclonic froth flotation cell
Inventor: CUTTING GEOFFREY WALTER
IPC: B03D1/14
Filed: 1985-07-18
Abstract: A cyclonic froth flotation cell, suitable for use in the separation of minerals comprises concentric inner and outer cyclones (2, 4). A liquid feed containing particles and injected dissolved air is fed tangentially via a conduit (7) into an inlet chamber (7a) below the outer cyclone and in communication with the inner cyclone. On contact with a stator (10), bubbles are generated which form a froth with hydrophobic particles in the feed. The feed passes up through the inner cyclone (2) and the froth is collected at the top of the cell. Exposure of the feed to shear, and hence froth formation, is enhanced either by recycling the feed through the outer cyclone into the inner cyclone, or by increasing shear and circulation within the inner cyclone by the use of flow modification assemblies therein. Residual feed and non-hydrophobic particles are re-covered from the outer cyclone (4) via an outlet (15). <IMAGE>
