Title: Stair gate that emits an alarm if gate is left open or latch left unlocked.
Inventor: HAWTHORN MICHAEL JOHN
IPC: G08B21/24
Filed: 1996-02-23
Abstract: In a latch 4 for a hinged stair gate 2, an alarm-activating reed switch (fig.4, not shown) is carried by a plunger 26 which enters a cup 24 to secure the gate closed, the cup being secured to an adjacent fixed frame member 6. The fixed cup 24 houses a magnet 30 which serves to hold the reed switch open when the plunger is introduced into the cup securing the gate. Since the switch is open, there is no power drain in this condition. Upon withdrawal of the plunger to open the gate, by raising an operating lever 22 of the latch mechanism, the reed switch becomes removed from the sphere of influence of the magnet and the switch reverts to its normal closed condition. Closure of the switch activates an alarm only after a set time delay, permitting opening and re-closure of the gate, by a carer, without activation of the alarm. The alarm may also sound to indicate a low battery.

Patent GB-2318173-A (GB)
Title: Heating arrangements
Inventor: COTTON JOHN
IPC: A47J31/54
Filed: 1997-10-08
Abstract: A heating arrangement for a domestic appliance, such as a coffee making machine (fig.1), includes an elongate passage through which water can flow whilst being heated. The heater itself 7 is arranged to make intimate thermal contact with the passage only at discrete, spaced regions 8-10 along its length; the regions being of average length 1 , and being separated by a distance of at least 31 from any other region. This arrangement produces hotter water than similar arrangements in which intimate thermal contact exists between the passage and the heater over their entire lengths. The regions may be formed by solder or spot-welding or by cut-outs from a web joining the heater and passage. Local vaporisation of the water adjacent these locations followed by turbulence, mixing and better heat distribution is thought to result from this arrangement - the heated water having a higher temperature than prior arrangements.
