Title: Controlling aluminium alloy strip production
IPC: G01N27/02
Filed: 1981-01-05
Abstract: In the production of aluminium alloy strip, in which hardening of the material is effected by heat treatment to dissolve pre-existing precipitates in the metal matrix followed by quenching and ageing, the electrical conductance of the strip after quenching is measured using a conductivity probe scanned across the width of the strip. Heating is controlled in accordance with the measured conductance so as to obtain uniform electrical conductance across the width of the strip. This measured conductance has a close correlation with the required mechanical properties. The conductance is measured by a transmitter 33 producing an electromagnetic field. The transmitter is movable on a C-shaped frame 35 across the strip. A receiver 36 picks up signals due to the eddy currents in the strip and provides an output processed in a computer system 57 to control the movement of flux modifiers of a transverse flux induction heater so as to control the strip heating. <IMAGE>

Title: Slide-back waveform analyzer
IPC: G01R19/00
Filed: 1981-01-06
Abstract: An apparatus for modifying a repetitive input signal by programmed variations of offset and gain such that the dynamic range of a waveform analyzer may be fully utilized is described. Initial offset and gain values are stored in a storage device 50. Then the input signal is applied to a summer 10 such that the signal plus the initial offset value is applied to a digitally-programmable amplifier 20. The output of the amplifier is then processed by a signal analyzer 30 where a list of offset and gain values needed to provide optimum resolution is calculated. The gain and offset data are stored in the storage device 50. Also calculated are the times at which offset and gain values should be applied to the input signal. The times are computed by counting clock pulses with reference to a pulse at the repetition rate of the input signal. These time data are sent to a controller 60 which addresses the gain and offset data stored in the storage device. The addressed data are output to a DAC 40 to produce an offset signal and to the digitally-programmable amplifier to alter the gain thereof. <IMAGE>

Title: Magnetic lock and key
IPC: E05B47/00
Filed: 1981-09-03
Abstract: A magnetic lock comprises an inner element 10 coaxial with hollow cylinder 18 which is in turn held in housing 19. Locking magnetic elements 47, 48, 49 are held in an axial groove on the inner member and also in a parallel axial groove 46 on the inner face of the cylinder 18 to prevent their relative rotation. The key 12 has magnetic regions which align magnetic elements 47-49 with apertures 6 joined to transverse grooves 57 so that limited rotation of the inner element 10 can occur. This moves axial rib 27 on bolt carrier 25 away from lug 41 on bolt 23 and also moves rib 28 against abutment 43 on the bolt. These movements permit and cause, respectively, bolt nose 39 to withdraw from aperture 32 in housing 19 so that inner member 10 and cylinder 18 may rotate together, thus moving arm 15 to unfasten a latch or other fastening. <IMAGE>

Title: Improvements in or relating to microwave circuits
Inventor: GRATZE STEPHEN CECIL
IPC: H01P1/208
Filed: 1982-09-04
Abstract: Conventional microwave circuits comprise dielectric resonators within a housing carrying tuning screws for fine adjustment of the resonance frequencies of the resonators. However, when in use, the circuits must be precisely positioned within an enclosure which may be inaccessible for tuning purposes. This problem may be overcome by employing resonators 6 within a housing 7 which is inserted as a unit into circuit after tuning the resonators 6. The housing 7 has a tab 7A over each resonator 6 and by adjusting the position of the tab 7A using a screw 9, the frequency can be altered. During the tuning operation, the circuit is located within a test container 8 which reproduces the electromagnetic environment of the enclosure within which the circuit will eventually be placed. <IMAGE>

Title: Lift crane
Inventor: HELM PERCY RALPH
IPC: B66C23/84
Filed: 1983-07-29
Abstract: A lift crane has a separate transporter-supported front ring segment (12) and a transporter- supported rear works (11) including a counterweight (18). The front ring segment (12) is connected by a frame element (48) to the rear works (11) and supports a carrier (20) which pivotally mounts a forwardly-inclined boom (26) and a rearwardly-inclined mast (27). Movement of the carrier across the front ring segment is permitted by two equal-length links (52) pivotally connected to opposite sides of the carrier (20) and the respective opposite sides of a horizontal bracket (50) mounted on the frame element (48). The centre of rotation of the carrier (20) as it traverses the front ring segment is substantially coincident with the imaginary apex of a truncated isosceles triangle formed by the carrier (20) and lines running axially along the links (52) and is also substantially coincident with a vertical axis (Y) running through the rearwardmost point of the mast. This point of the mast (27) thus remains substantially stationary during the movement of the carrier (20) across the front ring segment (12). A pendant (30) connecting the rearwardmost point of the mast (27) to the rear works (11) also remains substantially stationary and in a vertical plane during the movement of the carrier (20) across the ring segment (12), thus minimizing the amount of side loads and torsional forces induced in the mast (27) due to such carrier movement. <IMAGE>
