Abstract: 709,301. Rotary vibration-dampers. SINISTERRA, F. Nov. 15, 1951 [Nov. 24, 1950].. No. 26823/51. Class 108(3) A damping device comprises relativelymovable elements having smooth co-. operating faces, one of the elements com-- prising an enclosure, the faces de-limiting the enclosure to provide gaps of between .5, and 3 m.m. the enclosure containing a highviscosity filling under sufficient pressure to cause it to adhere to the faces. In the construction shown in Fig. 5 a rotor 35 carries a drum 39 of. cast light alloy and is mounted. by bronze rings 34, 36 in a steel casing 27.. Bouncing putty in the rotor spindle at 41 is acted on by a plunger 50, the spring loading of which is adjustable at 48. The space 41 is connected by ducts 42 with the peripheral space between the drum 39 and the casing. The damper is filled through a plug 43. In the construction shown in Fig. 7, the rotor 54 is formed with four circumferentially-spaced semi-circular peripheral recesses 61. The latter may, however, be shaped as a half ellipsoid or parallelopiped with rounded angles. The recesses may also be disposed in the wall of the casing, Fig. 3 (not shown). The angle between the tangents to the surface of the recesses and the surface of the rotor and/or casing (at the point at which these surfaces meet) may be other than 90 degrees in order to vary the damping effect. In addition to a shearing of the bouncing putty at the mouth of the recess a rotary movement of the putty may be induced within the recess by suitable choice of the above-mentioned angle. A number of dampers may be adjusted simultaneously by remote control, Fig. 9 (notshown. The putty space of each damper is separated by a floating piston from a hydraulic conduit. Each conduit is connected by a main conduit with a piston .and cylinder device by means of which the pressure in each damper may be varied..

Title: Improvements in and relating to the automatic regulation of the mixture of gases or liquids
IPC: G01G19/22
Filed: 1930-09-15
Abstract: 358,684. Mixing fluids in flow. MILLS, T. A., Laurieston, Saltburn-on-Sea, and BOSANQUET, W. S. B., Gainford, near Darlington. Sept. 15, 1930, No. 27450. [Class 86.] Apparatus for a u t o - matically regulating a mixture of gases or liquids (for example to maintain a mixture of constant calorific value) comprises a container through which the mixture is passed, the container being attached to a weighing machine having its beam adapted to be lifted or lowered on to its knife-edge, at predetermined intervals, by mechanical means, means being provided whereby any resulting deflection of the weighing machine closes one of two electrical circuits which cause a motor or motors to operate, in one direction or the other, a valve or valves controlling the flow of the gases or liquids. As shown, a mixture of gases is drawn from the main through a pipe 1 by an aspirator E and passed through a pressure regulator F, dryer U, and inlet seal C, to a container B suspended from a balance beam A. The mixture passes from the container B through an outlet seal D, pipe 4, and regulating valve G, and thence to the atmosphere or stack by a pipe 5, gas flow meter H, and pipe 6. The usual knurled knob for raising and lowering the balance beam is replaced by a pulley A<1> connected by a cord J to a lever L which is periodically rocked by a motor-operated cam M. A steel ribbon P terminating in platinum points P<1>, P<2> is secured at its centre upon a vertical slide moved up and down by means of a lever and tappet each time the balance beam is moved down or up into operative or inoperative position respectively. When the mixture of gases is correct, their weight within the container B maintains the balance in a central position so that when the beam is moved down on to its knife-edge by the cam M and the ribbon P is subsequently raised, the pointer A<2> enters a depression in the ribbon without disturbing the same. If, however, the mixture is incorrect, the balance is disturbed and the pointer bends the ribbon and causes one of the platinum points P<1>, P<2> to enter a mercury cup Q or Q<1>, thus closing a relay T and causing a motor to adjust a valve so as to restore the proportions of the mixture to the required ratio.

Title: Improvements in or relating to pulse signal receivers
IPC: G01S7/292
Filed: 1955-09-27
Abstract: 773,356. Radar; pulse signalling systems. SOC. FRANCAISE RADIO-ELECTRIQUE. Sept. 27, 1955 [Nov. 12, 1954], No. 27470/55.. Classes 40(5) and 40(7) The invention relates to means for improving the signal output from pulse radarreceivers and pulse communication receivers where the received signal is mixed with noise and interference. According to the invention such means consists of apparatus for delaying the received signal pulses by a time delay not exceeding their duration and adding the resultant delayed signal pulses to undelayed signal pulses. As shown in the Figure the output from the anode 4 of the final valve in a radar video frequency amplifier 3 is developed across load resistor 5. An open-ended delay line 8 consisting of sufficient low-pass filter sections to provide the required delay is connected across the load and pulses travelling down this line are reflected back and combined with undelayed pulses in the input to second video amplifier 6. The actual delay may in a practical case be from 0.2 pr.sec. to 2 pr.sec.; being always less than the duration of the signal pulses and greater than a lower limit dependent on the receiver bandwidth. Instead of a reflecting delay line one of transmission type may be provided, its output being combined with non-delayed signals. The delay may be obtained, in another modification, by means of a delay line connected between an amplitude limiter arranged to pass only signals of less than a predetermined amplitude and/or of more than another predetermined amplitude and an amplifier having a lower and/or an upper threshhold value corresponding to the limiting value or values of the limiter.
