Title: Methods and apparatus for intrusion detection having improved immunity to false alarms
Inventor: HOSEIT PAUL M
IPC: G08B29/18
Filed: 1994-01-07
Abstract: ABSTRACT A multisensor intrusion detection system having greatly improved immunity to false alarms is disclosed. This system employs a first sensor for sensing an intrusion in a volume of space by a first physical phenomenon and a second sensor for detecting an intrusion in the volume of space by a second physical phenomenon different from the first physical phenomenon.  The first sensor generates a first signal in response to the detection of an intrusion into the volume of space, and the second sensor generates a second signal in response to a detection of an intrusion.  A microcontroller generates an alarm signal upon the occurrence of one first signal and one second signal within a first interval, the occurrence of another first signal within a subsequent second interval and the occurrence of another second signal within a third subsequent interval.

Title: Heat exchanger assembly
Inventor: JURISICH MILNE
IPC: F28D9/00
Filed: 1993-03-01
Abstract: A heat exchanger has a core assembled of integrally formed modules (11). Each module encloses channels (17) separated by strengthening webs (16) and its large, flat, external faces carry respective arrays of fins (18, 19). By stacking the modules, with facing arrays of fins interleaving, further channels (20) are formed. The enlarged surface area of channels (20) compared with channels (15) (preferably these surface areas are in a ratio of over 7:1) makes the stack of modules suitable for heat exchange between parallel counterflows of fluids of differing heat capacities. Preferred apparatus has air fan-forced, via straight manifolds, through channels (20) - the interleaved fins serving to even out air temperatures and speeds across the channels' widths - whilst the ends of channels (17) are closed and a liquid (or liquids) enters and leaves channels (17) at right angles thereto although once in the channels (17) the liquid flows in parallel counterflow to the air flow.

Title: Combination faucet device
Inventor: ENOKI MASATOSHI
IPC: G05D23/13
Filed: 1993-12-24
Abstract: ABSTRACT OF THE DISCLOSURE    In a combination faucet device (10) according to the invention, a movable valve member (160) slidingly moves relative to a main casing (30) to change a mixing ratio of high-temperature water supplied from a hot water port (116) to low-temperature water supplied from a cold water port (106).  The movable valve member (160) is pressed by a temperature sensitive spring (130) in a first direction while being pressed by a bias spring (150) in a second direction opposite to the first direction.  The temperature sensitive spring (130) is exposed to water mixture and varies its spring constant according to the temperature of the water mixture.   The temperature sensitive spring (130) accordingly moves the movable valve member (160) in a direction for decreasing the ratio of the high-temperature water to a certain position where the spring force of the temperature  sensitive  spring  (130)  balances  with the spring force of the bias  spring  (150),  thus allowing water mixture adjusted to a target.
