Title: Hydraulic valve tappets
IPC: F01L1/25
Filed: 1969-10-02
Abstract: 1,235,225. Hydraulic tappets. GENERAL MOTORS CORP. 2 Oct., 1969 [16 Oct., 1968], No. 48408/69. Heading F2K. An hydraulic tappet comprises an inverted cup-shaped member 14, adapted to contact a cam 9, an inner member 16, adapted to abut the end of a valve stem 7, and a dished spring plate 18 disposed between inner member 16 and the closed end of member 14 to form a fluid reservoir 19, a ball valve 24 being adapted to close a central aperture 21 in the plate 18 when the tappet is under load. A resilient flexible diaphragm 28 supports the inner member 16 and forms a fluid reservoir 29 beneath the plate 18. A groove 26 in the upper surface of member 16 facilitates flow of fluid between the reservoirs 19, 29 when ball valve 24 uncovers aperture 21. In a modification, an inner member 56, Fig. 3, has a part-cylindrical upper surface 57 which provides a restricted passage 58 at each side of an opening 53 in a spring plate 52 for leakage of fluid from a pressure chamber 54 during the valve lift stroke. A spring 59 may be interposed between the spring plate 52 and the inner member 56. In a further modification, an inner member 73 incorporates passages 76, 77, and a flat valve plate 80 partly closes the passage 77 during the valve lift stroke. In each of the embodiments, a restricted orifice, such as orifice 22, Fig. 2, may be formed in the spring plate.

A device for hauling and shooting the trawl of a stern trawler comprises forward guideways, aft guideways 8 arranged above and aft of the forward guideways, a first hoisting trolley 3 movable in the forward guideways, a second hoisting trolley 9 movable in the aft guideways and a reversing pulley 4 whereby when the trolley 3 moves forward the net being hauled in is looped around trolley 3 and pulley 4 and when trolley 9 moves aft the net is raised to the emptying position. As shown, the device comprises a hauling device 1 which includes spaced-apart guideways and trolley 3; and a shooting device 5 which includes guideways 8 mounted on posts 6, 7 and trolleys 9. The trolleys 3, 9 consist of a shaft 10 with fixedly mounted toothed wheels 11 engaging racks 12 in their respective guideways. Also fixed to shaft 10 are cable pulleys 14 and remotely operated brakes 13. Trolley 3 also has an idler pulley (not shown) between pulleys 14. The net 18 is hauled in over the idler pulley of trolley 3 which is fixed in recess 2A and pulley 4 by winch 21 and line 21A. The trolley 3 is then released and moves forward along its guideways being pulled by cables 22 which are attached at one end to cable drum 19 and at the opposite end to posts 7 at position 23. When part 29 of net 18 reaches slipway 30, trolley 3 is fixed, cables 22 are released from posts 7 and fixed to the forward end of part 29 and trolley 9 is released so that the part 29 is hauled into the emptying position over hatches 31. For lowering the net the procedure is reversed. Fig. 2 (not shown) illustrates an arrangement where the trolleys are operated by separate cables.

Abstract: 1483654 Receiver digital frequency indicator; transistor limiters and sinewave to pulse circuits LICENTIA PATENT-VERWALTUNGS-GmbH 20 Nov 1974 [24 Nov 1973] 50236/74 Headings H3Q and H3T In a circuit arrangement for the digital indication of frequency in an AM and FM receiver including AM and FM local oscillators 3 and 1 the oscillations provided by each of the oscillators are fed via an amplifier 8 to an electronic counter 12 and a display 13 co-operates with the counter 12 to indicate a frequency to which the receiver is tuned and the coupling of the amplifier 8 to the oscillators 1, 3 is such that the oscillators are not detuned by changes in capacitance of the amplifier. As shown Fig. 1 the coupling is by capacitors 5 and 6 and the capacitance of a lead 14 to ground is indicated by 7. The outputs of the oscillators 1 and 3 can be coupled to series connected inductances (17, 18, Fig. 2, not shown) connected by a lead (19) to the input of amplifier 8. The division ratio of a predivider 9, which can be flip-flops in integrated TTL, is selected in accordance with the AM or FM oscillator 3, 1 in use. The output pulses from the divider 9 are gated at 10 during predetermined periods and counted by the counter. Connection is made to take account of the IF in use so that optical indicator 13 displays the received frequency. In a modified divider arrangement (Fig. 5, not shown) for AM operation the signals from a predivider (63) are switched by a switch 65 to by-pass a predivider (64) so as to pass directly to a predivider (66) which also includes the gate 10. For FM operation the by-pass path 67 is closed and predivider 64 is brought into use. Wide band amplifier 8 has a band of 0À5 to 120 MHz and can be as shown in Fig. 3. The oscillations from the oscillators 1, 3 are converted to rectangular oscillations 40 in that overmodulation i.e. limiting occurs at the transistor 25. Current stabilizing feedback is provided via 27 and inductances 23 and 30 prevent a reduction in amplification at high frequencies. In a modified amplifier (Fig. 4, not shown) the diode 28 coupling is replaced by capacitive (48) coupling.

The gain of a pure fluid amplifier comprising a power nozzle 4, Figs. 2a, 2c, discharging to a plurality or receivers 12, 13, 14, 15, 16 under the control of a nozzle 6 is varied by the provision of a second control nozzle 9. As the flow from the nozzle 9 is increased, deflecting the main flow upwardly, the gain is reduced since a greater signal from the nozzle 6 would be required to deflect the main flow into one of the upper receivers than into one of the lower receivers. A second set of receivers 22.... 26 and an additional control nozzle 27 may be provided. The receivers may be arranged as in Fig. 3b, their openings lying in a plane that is not normal to the axis of the undeflected main flow, or they may be o f varying area as in Fig. 4b.

Abstract: 1528089 Unloading loose particulate material SCANIAINVENTOR AB 8 Dec 1976 [17 Dec 1975] 51246/76 Headings B8H and B8S Apparatus for unloading loose particulate solid material 38 into a supply 39 includes a supply pipe 10 with positive discharge device 16, illustrated as a conveyer screw 18, driven by a motor 20. As shown in the embodiment illustrated in Fig. 4 the pipe 10 is telescopic and the pressure of material at outlet end 17 is sensed by a diaphragm device 35 to control the vertical positioning of the outlet end 17, to keep the pressure on the conveyer screw relatively constant, through a motor 25 driving a drum 24 on which is wound a hoist rope 23 attached to a beam 22. The arrangement results in the material 38 being forced out below the level of the supply 39 so that the material already in the supply 39 acts as a dust trap. In the embodiment shown in Fig. 3 the discharge pipe 10 is mounted on a crane structure being connected at 50 to a feed conveyer 51 pivoted at its opposite end to a gantry crane 52. The pressure of the material at the discharge end of the positive discharge device 16 is sensed by a device sensing the load on the motor 20 driving a conveyer screw 18 as in Fig. 4. The load sensing device controls the positioning of the discharge end 16 of the pipe 10 vertically and/or laterally through motors 25, 25a, 25b, 25c respectively acting to luff the conveyer 51 through rope 53, to drive the gantry crane 52 along rails (not shown), to regulate the angle between the pipe 10 and the conveyer 51 and to slew the upper parts of the apparatus through a turntable 56.

The wall 1 of a camera carries an accessory shoe 2, in which is a contact 3 mounted in an insulator 4. Fixed to the base of contact 3 is a leaf spring 5 carrying a pin 6 of insulating material which projects upward through an opening in wall 1 and shoe 2.

Fig. 3 (not shown) is a modification in which the contact device in the shoe is connected to a further contact device located elsewhere in the camera, and so arranged that the contact device in the shoe is inoperative when the further contact device is in use. Thus the further contact device may be used for an electronic flash attachment when some accessory such as a rangefinder is inserted into the shoe.
