Title: High frequency heating apparatus control compensates for magnetron temperature variations
Inventor: TAKEI TAMOTSU
IPC: H05B6/68
Filed: 1991-06-20
Abstract: In a high frequency heating apparatus such as a microwave oven, the temperature of a magnetron 17 varies during periods of operation and non-operation and the magnetic field and hence the anode voltage drop with temperature increase whereby the high frequency output power would decrease if the anode current was maintained constant (as in the prior art). To overcome this problem, a counting means 27 is caused to have a set count indicative of magnetron temperature and the on period of a switch 12 in a magnetron driving inverter 1 is adjusted in dependence on that count so that the input current to inverter 1, and thus the high frequency output of magnetron 17, is rendered substantially constant. The counting means 27 may comprise a counter which counts up and down during operation and non-operation respectively of magnetron 17, and the count up rate is increased as the desired output power is increased. The inverter 1 may be controlled to increase the anode current stepwise every time the count increases by a predetermined value. In an alternative, the set count is the difference between the counts in first and second counters which count up during operation and non-operation respectively of the magnetron. <IMAGE>

Patent GB-929774-A (GB)
Abstract: 929,774. Change speed control. DAIMLERBENZ A.G. April 19, 1962 [April 26, 1961], No. 15382/62. Addition to 831,058. Class 80 (2). In a change speed control in which an element for non-positively changing gear in a planetary train is shifted automatically from partial to full engagement on torque reversal, an accumulator provides power for the partial engagement and is connected to the gear changing element by the control member during the phase. The change-speed control mechanism of the parent Specification is modified by the addition of a control slide valve 16 and an accumulator 29, the valve 16 being sensitive to torque direction change in a splined clutch plate 13 or a band brake, through a lever 15. In the condition shown, in which the clutch is disengaged by a spring 12, the main supply is connected to charge the accumulator 29 through line 33 and the clutch is exhausted through lines 27, 25. A signal pressure in line 41 moves the valve 34 to pass pressure by line 24 to move valve 16 against spring 22 which opens the clutch line 27 to the accumulator line 28 to provide light engaging pressure. On torque reversal in the clutch, the valve 16 is returned to the position shown, cutting off the accumulator line 28 and connecting the clutch line 27 with the main pressure line 39 through line 25. In a modification a restricted supply between lines 25 and 27 provides for fluid leakage and a manually controlled valve supplies full pressure to the left-hand end of valve 16 for gear changes during braking. The invention may be similarly applied to a band brake control as shown in the prior Specification.

Title: Polymeric surge arrester with parallel connected disconnect device and backup device
Inventor: DOONE RODNEY MEREDITH
IPC: H01T1/14
Filed: 1995-09-13
Abstract: For enabling ready location of failed varistor surge arresters 1 of the type having a polymeric outer housing and which commonly are visually intact even when failed, a disconnect device 2 (known per se) is coupled in series between the arrester 1 and ground 6. Failure of the arrester 1 results in a grounding cable 5 falling free from the device 2, thereby providing a visual indication that the arrester 1 has failed. To overcome the problem that equipment coupled to the power line normally protected by the arrester 1 is then left unprotected, a backup device 3, in the form of a spark gap or varistor, is connected in parallel with the disconnect device 2 so as to provide a backup path to ground in the event that the line is again struck by lightning. The backup device 3 has such characteristics that it does not prejudice normal operation of disconnect device 2 on failure of arrester 1. For example, for a surge arrester 1 rated at 11KV to 34 KV, a spark gap in the disconnect device 2 may arc over at 2.5KV and a spark gap in the backup device 3 may be set not to arc over below 5KV. A spark gap type backup device 3 may have a resin main body (20,Fig.3), spark gap electrodes (21,22) separated by a ceramic spacer (23), and a spring loaded metal slug (28) soldered into a bore in electrode (21) so that in the event of an excessive ground fault current flowing for too long, the solder melts and slug (28) is moved by spring (29) to bridge the gap between electrodes (21,22).
