The clutch supply pressure acts on a smaller area of the valve spool 138 than the clutch chamber pressure. A restriction 146 in the clutch chamber supply limits the rate at which the chamber 116 is filled and thus limits the rate of clutch engagement. The pressure in the chamber 116 acts on the clutch plates 72, 76 through a presser plate 112 which is biased towards the disengaged position by springs 122. As shown in a double clutch for a marine reverse gear the clutch 72, 76 selectively connects the housing 52, 54, 56 to a first, forward drive, output shaft 48 whilst a similar clutch 64, 68 connects the housing to a second, reverse drive, coaxial output shaft 50. A shield 148 prevents lubricating oil for the bearings and clutch plates from entering the clutch engaging chambers 116 118. In Fig. 7 (not shown) the valve spool is additionally biased radially inwardly by the centrifugal pressure generated in a fluid column (156).

Abstract: 601,583. Circuits for light-sensitive cells. TRIGGS, W. W. (Patelhold Patentverwertungs- & Elektro-Holding Akt.-Ges.). Nov. 26, 1942, No. 16806. [Class 40 (iii)] [Also in Groups XXXVIII and XL (c)] In - apparatus for preventing interference from disturbances arising within the apparatus, oscillations are received by two separate but immediately adjacent and similarly arranged receivers having the same directive action and the same transmission properties, and similar amplifiers having the same frequency-band widths. In this way, phase differences between the : two amplified oscillation paths . are minimized and are independent of the direction of incidence of the incoming oscillations. The outputs from the two paths are applied to a modulator to produce the signal, the mean value of which is proportional to the square of the amplitude of the oscillations received. Light, infra-red or ultra-violet waves may be used and be received by photo cells. Fig. 5 shows an arrangement in which a pair of photo cells P1, P2 which may be housed in the same bulb and are mounted directly side by side near the focus of a common optical collecting system L. The cells may be of the type in which two anodes co-operate with a common cathode. The receiver provides two parallel paths, including amplifiers V1, V2 and filters F1, F2, the output from which is combined in the balanced modulator M and applied through filter B and amplifier V5, if desired, to a recorder or telephone receiver. The filter B may suppress disturbances by transmitting only the frequency range of the signals it is desired to translate ; alternatively multiplex signalling may be used, in which case the filter selects one of the particular channels. In arrangements of this kind where a D.C. signal is used, an interrupter, e.g. a rotating disc, may be provided to obtain easily amplified alternating currents. The frequency of the received signals may be varied for secrecy purposes and the system used for detecting signals of unknown or varying frequency by using broad band amplifiers. Phase adjusting links may be included in one or both the channels to compensate small phase deviations. Specification 443,582 is referred to.
