Title: Baggage checker for weapon detection - uses remanent magnetism to detect ferromagnetic object concealed in nonmagnetic material
IPC: G08B13/24
Filed: 1975-06-11
Abstract: The baggage checker detects weapons enclosed in aluminium and even when amongst objects such as keys or coins. Ferromagnetic objects are detected by measurement of the remanent magnetic field after their magnetisation. A capacitor (C1) is charged from a power supply (DC) via a switch (S2) and is discharged into a frame coil (c) via another switch (S1) in order to induce a magnetic field. A diode (D1) prevents the self inductance from re-charging the capacitor in the opposite direction. The coil is then switched (S1) to an amplifier (A) input which operates an alarm if a ferromagnetic object was present during the magnetisation period. A capacitor (C2) is connected to the coil to form an oscillatory demagnetisation period. A capacitor (C2) is connected to the coil to form an oscillatory demagnetisation circuit.

Title: Thermodynamic process for IC engine - has combustion partly at constant volume and partly during isothermal expansion
IPC: F02B1/06
Filed: 1976-01-28
Abstract: The engine draws air in at constant pressure (3) and then compresses it adiabatically (4). Fuel is then introduced and burnt at constant volume (5) until the peak pressure (P1) is reached. Further fuel is burnt during the expansion stroke (6) so that this stroke is isothermal. At the end of expansion heat is rejected at constant volume (7) and finally the exhaust gases are discharged at constant pressure (8). 80% to 90% of the fuel is burnt during the constant volume phase (5) and the remainer during the isothermal expansion (6). The cycle reduces the peak pressure below that of other internal combustion engine cycles whilst maintaining a high temperature during expansion and this combination reduces the production of nitrous oxide in the exhaust.
