Title: Electronic security systems
Inventor: EDSON JAMES B
IPC: G07C9/00
Filed: 1982-08-25
Abstract: An electronic security system is provided with multiple levels of access in which a higher level pass code gives the user access to numerous system functions, such as disarming of the system, resetting, system testing, loop by-passing, and system programming, whereas a lower level pass code gives the user access to fewer functions, in one embodiment to disarming only a portion of the system. In one embodiment, an erasable memory 120 is programmed with a number representing a temporary pass code after the entry of a higher order pass code by the individual setting the temporary pass code. The permanent pass code may be made more complex than the temporary pass code to provide an extra level of security by providing that the permanent pass code has more digits. Timing circuitry 118, 119 is provided to establish a temporary pass code entry window during which a temporary pass code may be entered into the erasable memory. No entry of a temporary pass code within the allotted time results in a disabling of the temporary pass code system. <IMAGE>

Title: Air lift de-sludging system
Inventor: CHITTENDEN JEREMY BARROW
IPC: F04F1/18
Filed: 1983-04-13
Abstract: Sludge and water are raised in succession by an air-lift (12, 18). A probe (34) is positioned above the height reached by discharging sludge, but low enough to be washed by discharging water. When water starts to flow the probe (34) is washed, and stops the air supply (16) to the air lift. This technique is used in periodic automatic de-sludging of a settling tank (2) whose bottom outlet is connected (10) to the air lift (12, 18). <IMAGE>

Title: Temperature measuring device
Inventor: YAMAZAWA AKIRA
IPC: G01K13/00
Filed: 1983-05-05
Abstract: A temperature measuring device comprises a source (1) of a reference signal whose frequency is substantially independent of temperature, a source (4) of a temperature dependent signal; and a counter (5) for counting pulses of the temperature dependent signal occurring in a predetermined period derived from the reference signal. Latch (7), decoder (8), driver circuit (9) and display (10) receive the output of the counter to provide an indication of temperature. The counter has fewer stages than the number of stages required to count all the pulses corresponding to expected clinical temperatures occurring in the predetermined period. A further counter (6) counts the MSB's: in dependence on this an indication of out-of-range temperature may be displayed. <IMAGE>

Title: Milk abnormality testing aid
Inventor: VAUGHAN RAY
IPC: G01N27/06
Filed: 1983-05-12
Abstract: A device for testing the level of mastitis in milk comprises a conductivity sensor or cell for receiving a milk sample to be tested. The resistance R of the milk sample in the cell is arranged to be compared with the resistance of a resistor R10, the result of the comparison being indicated by red and green LED's D1 and D2. When the milk sample is of higher resistance than the resistor R10, the green LED is energised but when the milk sample is of lower resistance than the resistor R10, then the red LED is energised and the green LED is extinguished. The resistance value of the resistor R10 may be preset at a fixed level or may be arranged to be swept downwardly from high to low values whereby the LED's change over when equivalence of resistance is attained. The variable resistor R10 can be calibrated to enable the corresponding mastitis level to be read off. <IMAGE>

Title: Brake device
Inventor: YEOMANS WILFRED ERNEST
IPC: B65G13/075
Filed: 1983-07-15
Abstract: A static anti-run brake device of limited torque has two relatively rotatable co-axial members 10, 11, and a plurality of elongated resilient elements 21 mounted on a first 10 of the two members and having their free ends in abutting contact with an annular surface on the second member, the lengths of the elements 21 being such that upon rotation between the two members in a forwards direction the free ends of the elements 21 are deflected by sliding contact with the annular surface 22 into a first operative position in which the ends are inclined in the reverse direction and exert negligible braking torque. Upon reverse rotation between the two members the frictional resistance between the free ends of the bristles and the surface 22 causes bending of the elements and thereby exerts a braking torque resisting reverse rotation until the free ends of the elements are inclined in the forwards direction and again slide around the second member. The elements may be bristle-like filaments 21 e.g. of black nylon in a brush screen and the brake device may act as a seal for a bearing of an idler conveyor roller as in Figure 4. Modified rollers are shown, and in Figures 6,7 the elements are in the form of leaf springs (71). <IMAGE>

Title: A system and method for the recovery of waste heat from exhaust steam
Inventor: SMITH ROBERT JAMES SWINTON
IPC: F01K19/04
Filed: 1984-11-06
Abstract: Waste heat is recovered from the exhaust steam of a steam engine by passing the steam through cooler 2 from which it is delivered at or slightly above atmospheric temperature and pressure as mixed steam and condensate to a compressor that delivers the mixture as water at about 245/250 DEG F to receiver surge tank 4. Feed pump 6 returns the water from receiver 4 to the boiler. The compressor, receiver and feed pump are grouped together in a casing through which flue gas is circulated at about 270 DEG F by a fan. Air is admixed with the gas under control of a valve. Cooler 2 may contain water cooling tubes providing a path to an outlet or it may consist of a jet spray cooler. The compressor may be rotary, particularly a turbo-compressor. <IMAGE>

Patent GB-2154813-A (GB)
Title: Electric water heaters
Inventor: LEWIS ROBERT
IPC: G05D23/19
Filed: 1985-02-28
Abstract: Water flowing through the heater is heated to a predetermined temperature and booster means 8,9 are operable to increase the heater power output and increase the water flow rate without causing a significant variation in said temperature. A control circuit which prevents unlimited operation of the booster may have timing means which terminates operation of the booster after a predetermined time and then inhibits a further operation of the booster for a predetermined non-operational period. In normal operation, the heater may operate at a current equal to or less than the maximum continuous current which the supply circuit is designed to carry, whereas that design current is exceeded when the booster is in operation. The control may then keep a running total of the extent to which the energy used by the heater exceeds, or is less than, the energy that would be dissipated if it ran at the design current, booster operation being terminated if the running total exceeds a predetermined value. A main heater 7 in a water duct 3 is controlled by a temperature sensor 10 and operates in normal use. When a boost button is pressed, a solenoid valve 8 opens and a booster heater 9 in a water duct 4 is operated at a fixed power level, the sensor 10 continuing to control the heater 7 so that the water temperature in a common outlet duct 6 remains at the set level. Alternatively the rate of flow of water may be adjusted by thermostatic means. <IMAGE>
