Title: Improvements relating to load trip circuits
Inventor: ALDER JOHN
IPC: H02H11/00
Filed: 1983-05-14
Abstract: A load trip circuit comprises a plurality of transistors (TR1 to TR7) in which consequent upon the switching of the arrangement into operation a DC supply (+28V) is initially connected to the load (connected to terminal O/P) through one transistor (TR5) which is momentarily rendered conducting. During this momentary conduction of the transistor the load resistance is tested by monitoring the development of a voltage at terminal O/P which is representative of the resistance of the load and which renders another transistor (TR3) conducting when the voltage reaches a predetermined value indicative of the absence of short-circuiting in the load in order to supply current to the load. Under overload or short-circuit conditions in the load the transistor (TR3) is rendered non-conducting in order to disconnect the load supply. <IMAGE>

Title: A.C. motor control
Inventor: BAX ANTON MARCEL
IPC: H02P25/14
Filed: 1985-09-26
Abstract: A control system for a three phase motor (2) has two triac switches (30B and 30C) connected in respective supply lines (15 and 16) to the motor. Both switches (30B and 30C) are initially closed so that power is supplied to the motor on all three lines (14 to 16). After a predetermined time, when the motor (2) has reached its operating speed, one switch (30C) is opened by a logic unit (60) so that single phase power is supplied to the motor on two lines (14 and 15). The one switch (30C) is subsequently periodically closed for short intervals, and the other switch (30B) is periodically opened for short intervals under control of a monostable unit (80), so as to produce hunting of the motor. Hunting of the motor (2) is detected by a speed monitor (90) responsive to the back EMF of the motor. The system has a phase detector (40) responsive to the phase relationship between signals on the supply lines (14 to 16) which prevents the switches (30B and 30C) being closed, if there is not the desired phase relationship between the signals. <IMAGE>

Title: Improvements in and relating to absorbers for heat pump systems
Inventor: FITT PETER WILLIAM
IPC: F25B37/00
Filed: 1985-10-29
Abstract: An absorber for an absorption heat pump system comprises a circulation loop (10) comprising an upwardly extending passage (11) through which liquid flows upwardly and a return path (12), including a reservoir (13), for returning liquid from the upper end of passage (11) to the lower end. Inlets (17) and (18) are provided at the lower end of passage (11) for liquid and vapour, the introduction of the vapour into the liquid inducing circulation of liquid in the loop (10), and an outlet (19) is provided for withdrawing liquid from the reservoir. In use liquid continuously circulates through loop (10) with the addition of vapour through inlet (18), the vapour being absorbed in the liquid during flow of the liquid through passage (11). On a continuous basis or intermittently, liquid is supplied to the absorber through inlet (17) and removed from the absorber through outlet (19). Heat produced as a result of the exothermic absorption of the vapour in the liquid in the passage (11) is removed by heat exchange with a cooling liquid flowing around the passage (11) in the opposite direction to flow of liquid in the passage (11). <IMAGE>
Patent GB-855320-A (GB)
Abstract: 855,320. Turnstiles. UNIVERSAL CONTROLS Inc. Sept. 15, 1958, No. 29518/58. Class 106 (3). The money put in an inlet 22 by a depositor wishing to pass through a turnstile is scattered on to an inspection plate 26 for visual inspection by an attendant, who locks the turnstile if the money is incorrect, by means of treadle 138 and links 134, 124, 120, 114, 110 and pawl 102 which has a locking finger 106 which engages the teeth on a disc mounted on the turnstile shaft. If the money is correct, actuation of the turnstile by the depositor causes cam-actuated shaft 70 and links 82, 88, 92, 96 to swing baffle 30 so that roller 32 releases plate 26 and the money falls on to baffle 30 which now blocks mouth 52. When shaft 70 returns under spring influence, baffle 30 drops to allow the money to fall into container 36. The container 36 is mounted on roller feet 38 for easy removal. The turnstile may be permanently locked by a device on disc 128.
