Title: Method and composition for the evaluation of phagocytic response
Inventor: CAPONE JAMES JOSEPH
IPC: G01N33/52
Filed: 1983-12-05
Abstract: A method and composition for measuring the ability of an organism to resist infection are described. A sample of blood cells is taken from an organism. The phagocytic activity of the phagocytes in the blood is estimated by mixing the cells with zymosan particles or polymeric beads coated with protein and a luminescent chemical. When the phagocytic cells are mixed with either of these compositions, the cells engulf the particles thus causing the activation of the cells' biochemical mechanisms. Oxygen intermediates result from this mechanism causing a reaction with the luminescent chemical resulting in the production of light. This light is measured on a luminometer and based on the rate of light production and the maximum produced, the phagocytic activity of said cells is measured.

Patent GB-2150716-A (GB)
Title: Electric water heaters
Inventor: LEWIS ROBERT
IPC: G05D23/19
Filed: 1984-11-08
Abstract: An electric water heater has electrical heating means (8) for heating water flowing through it to a shower rose (15). The temperature of the heated water is sensed by temperature sensor (13) which causes a controller (9) to vary the power output of the heating means to cause or attempt to cause the temperature of the heated water to remain at a predetermined constant value. If the power output of the heating means rises to or above an upper limit the controller causes a motor (6) to alter the setting of a constant-flow valve (4) so as to reduce the rate of flow of the water. This enables the user to have a hot shower even on a very cold day, though with a somewhat reduced flow of water. If the power output then falls to or below a lower limit the motor re-opens the valve. The predetermined water temperature may be varied by the user. <IMAGE>
