Title: Improvements in or relating to electron discharge valve amplifiers
IPC: H03C3/02
Filed: 1945-09-22
Abstract: 604,152. Wide-band amplifiers. PERCIVAL, W. S. Sept. 22, 1945, No. 24588. [Class 40 (vi)] A wide band amplifier comprises a filter of the kind described in Specification 517,516 for (a) converting a wide band signal into a plurality of signals occupying contiguous frequency ranges for amplification separately and subsequent recombination ; (b) combining separated responses occupying contiguous frequency ranges to form a single wide band output, or (c) passing only the frequency band which an associated amplifier delivers undistorted, a plurality of such channels covering the full frequency range of the input signal and reproducing the original form'in a common output circuit. Filter 1 accepts a wide band signal at terminals 2 and delivers at terminals 3, 4, 5, three separate output signals occupying the upper, central and lower thirds of the frequency spectrum respectively. Amplifiers 6, 7, 8 are arranged to give the same amplification and time delay to the signals in the wavebands fed to them and the three amplified signals are combined in the common output circuit to reconstitute the original signal in amplified form without distortion. When the input signal is low it may be fed directly to amplifiers having different pass-bands corresponding to contiguous sections of the frequency spectrum, the separate bands being recombined in the filter by feeding the outputs from the amplifiers to terminals 3, 4, 5 &c. and taking the reconstituted signal from terminals 2. Alternatively, three separate filters may be used to pass only the frequency band which its associated amplifier delivers undistorted, and the original signal may be reconstituted by connecting the outputs of the filters in parallel. Each amplifier stage may include a mixer with a common or individual local oscillator to heterodyne each signal component to a high frequency for separate transmission, the components being recombined at the receiver to restore the original signal form.

Abstract: 1,032,542. Clutches; springs. G. W. SEIFERT. June 20, 1963 [June 20, 1962; Dec. 20, 1962; April 19, 1963], No. 24666/63. Headings F2C and F2S. [Also in Division F1] A friction clutch in the drive of a vehicle engine cooling fan is engaged and disengaged rapidly by thermally responsive means. As shown in Fig. 1 the temperature responsive control member is arranged in the flow of cooling air and is constituted by a bimetallic strip 18a arranged behind a radiator 31 and having a hook-like element 39 for operating a snap spring 38a. The snap spring 38a carries by means of a short spring 34 a pressure pin 16a which cooperates with a clutch part 8a which is in screwthreaded connection with the hub 12a of the fan. The clutch part 8a is connected by a torsion spring 36 to the fan body 28 and co-operates with a clutch part 13a fixed to the driving wheel la. Above a desired operating temperature the bimetallic strip 18a gives a sudden reversal of shape to the snap ring 38a causing the coupling pin 16a to press the clutch part 8a into engagement with the part 13a. The fan blades 11a are connected to the fan body 28 by means of a slipping clutch comprising friction surfaces 41, 42 engaged by a cup spring 43 and centrifugal balls 44. In the embodiment of Fig. 3 (not shown) a bimetallic strip 18b is formed as a snap-over spring and is arranged behind a radiator 31b. The bimetallic spring 18b is operatively connected to a pressure plate 51 engaging pressure pins 16b which below a predetermined temperature engage a coupling part 8b to disengage the clutch. The clutch part 8b is formed with a screw thread engaging balls 44 mounted in the fan hub 12b and is urged by a spring 26b to engage a clutch part 13b fast with a driving wheel 1b. The wheel 1b is also connected to the fan by means of an hydraulic slip clutch comprising projections 53 formed on the clutch part 13b which are adjacent surfaces 54 of the fan body 28b and which cause the formation of a ring of oil during operation. The embodiment of Fig. 5 (not shown) is generally similar to that of Fig. but the hydraulic slip clutch comprises projections 64 formed on the fan body 28c and projections 63 formed on a ring 62 fast with the coupling part 13c and producing a centrifugal ring of oil in a chamber 65 sealed by a ring 40c having a lip 66 engaging the outer periphery of the clutch part 13c. During relative movement the projections 63 conduct sprayed oil to the sealing lip 66 to prevent wear. In a modification the projections 63 are carried by spring arms which extend under the influence of centrifugal force and which are otherwise removed from the centrifugal ring of oil.

Filed: 1971-04-19
Abstract: 1339509 Filtration in hydraulic circuit ROBERT BOSCH GmbH 19 April 1971 [21 May 1970] 24903/71 Heading BID In a hydraulic circuit wherein pre-delivery pump 61, filter 63 and main pump 65 are arranged in series to deliver fluid from reservoir 69 to load 67, a fluid-operated valve 72 is moved by a rise in pressure loss across filter 63 so as to reduce the flow through the filter. In Fig. 3 valve 72 short circuits main pump 65, so flow through the filter stops. The output pressure of pre-delivery pump 61 is limited by a valve 68 controlled directly by said pressure. In Fig. 4 (not shown) the fluid-operated valve (97) operates a hydraulic motor (90) to reduce the variable delivery of the main pump (85) to a minimum. In Fig. 1 (not shown) pressurelimiting valve (29) has three positions, in the two open ones of which it delivers fluid to operate a by-pass valve (37) to a first position wherein the main pump (16) is connected to the load, a fluid-operated valve (22) operated by the pressure drop across the filter delivering fluid to move valve (37) to by-pass pump (16) if the filter clogs. In Fig. 2 (not shown) the main pump is of the variable delivery type whose output control is moved to the minimum setting and locked there by fluid from valve (22) if the filter clogs. When not held in their minimum positions the output controls of main pumps in Figs. (2, 4) are manually adjustable. The circuits described ensure that only filtered fluid ever reaches the main pump and load and that the filter is protected from damage by reducing the flow therethrough if the pressure loss across the filter rises.
