Title: Improvements relating to the measurement of electrical parameters
IPC: G01N27/26
Filed: 1966-02-23
Abstract: 1,095,819. Measuring current/voltage characteristics. V. VESELY. Feb. 23, 1966 No. 7916/66. Heading G1U. An arrangement for automatically indicating the current-voltage relationship between the electrode potential of a test electrode 3, immersed in an electrolyte 2, and the current flowing through the electrode and electrolyte and a further electrode 4, incorporates a sensing electrode 5 adjacent the test electrode to detect the electrode potential, and a variable current source SQ connected between the test and further electrodes. The sensed voltage at the electrode 5 is compared at A with the voltage from a source SP, which may be incrementally adjusted or varied continuously. The difference signal is applied to an amplifier AV, both directly and via a channel including a chopper ZH, amplifier WV and integrating detector ID, so that an amplified version of the average value of the voltage at A is superimposed on the instantaneous value, so that this is relatively de-emphasized, and the system stabilized. The output of the amplifier AV is used to control the output of SQ so that it provides such a current that the electrode potential balances that provided from the source SP, and the current is determined on the indicator MI. The inverse characteristic may be recorded by throwing the switch 10 so that voltages picked off at 9 corresponding to the current from source SQ are compared with these from SP, and the resulting electrode potentials are determined on the indicator MU.

Title: Improvements in and relating to safety devices for gas burner installations
IPC: F24H9/20
Filed: 1935-03-18
Abstract: 437,011. Safety devices for gasheated appliances; thermostats. JUIV - KERS & CO., GES., 35, Junkerstrasse, Dessau, Anhalt, Germany. March 18, 1935, No. 8404. Convention date, Oct. 5, 1934. [Class 126] [See also Group XIII] In a gas-heated appliance, such as the waterheater shown, having a damper or throttle 23, 24 in the outlet flue, a control device 26, 27 is provided which closes the gas valve 28 when partial or total closure of the damper causes the combustion products to take the path in which it is situated. Continued passage of combustion products into the room is therefore avoided, by the extinguishing of the burner flames, should the flue damper be accidentally closed. In the form shown, the control device is a thermostat comprising two bimetallic bowed members 26, 27 connected together at one end so that their movements are additive; it is connected to the gas valve 28 by a rod 29 passing through a tube 30. The dampers 23, 24 are opened by the action of a bi-metallic bow thermostat 25 when it is heated by the combustion gases, this thermostat operating more quickly than that controlling the gas valve so that on lighting the apparatus the flue damper is opened before the gas-control thermostat has time to operate. The latter may be replaced by any form of control influenced by the gases, for example by their pressure or chemical action.

Abstract: 1,140,901. Valves. PETROL INJECTION Ltd., and H. E. JACKSON. 18 Feb., 1966 [26 Feb., 1965], No. 8528, 65. Heading F2V. [Also in Divisions F1 and G3] In a continuous, low-pressure fuel injection system an engine-driven pressure pump, Fig. 2, supplies fuel to a housing 32 containing an engine-driven rotor 33 which contains a ball 38 movable in a radial guideway formed by toothed members 37. The fuel pressure in the housing 32 assumes a level which balances the centrifugal seating force acting on the ball and fuel flowing round the ball passes via the central chamber 35 and relief valve 41 back to the float chamber 6. Relief valve 41 may be omitted. A fuel metering valve 13 has a piston 88, Fig. 5, and compartment 98 exposed to the inlet manifold pressure respectively via port 106 and flow restrictor 109 and via port 108. Diaphragm 97 is flexed to increase the seating force on valve 94 thereby decreasing the leakage of ambient air into chamber 61 and increasing the vacuum therein. Piston 88 moves to compress spring 102 which exerts an unseating force on valve 94 and takes up a position dependent on the inlet manifold pressure thereby pivoting cam 78 to move cam follower 80 thus rotating valve 67, Fig. 7, to vary the metering orifice defined between V-slot 68 and aperture 71 in sleeve 69 which in turn controls the fuel flow from inlet 75 to outlet 77. A screw 83 meshes with a gear 82 on sleeve 69 to provide datum adjustment of slot 71.

Title: Improvements in or relating to vibrating unit for screens and similar vibratory structures
IPC: B06B1/16
Filed: 1947-03-31
Abstract: 639,842. Jigging-conveyers. NORDBERG MANUFACTURING CO. March 31, 1947, No. 8618. Convention date, Aug. 4, 1944. [Class 78 (i)] [Also in Group XXIV] The invention relates to units of the unbalanced rotor type for vibrating sifting screens and similar vibratory structures and having a weight mounted thereon which is normally held in fixed position relative to the rotor by yieldable means in which position the rotor is substantially balanced until a predetermined speed of rotation is attained at or above which the weight moves radially outwards to produce unbalance of the rotor and cause vibration of the apparatus. According to the invention resilient snubbing means are associated with the rotor and are adapted to cushion the shock resulting from the stoppage of the weight as it reaches its outer limit of movement. As shown, weight 32 is held in normal position by springs 35 compressed between head 36 and the interior face of the portion 12 of the rotor. Head 36 is adjustable on a bolt 37. Shock-absorbing washers 41 and 45 are provided between the weight and the shaft portion 12 and a snubber spring 43 is interposed between the lower wall of portion 12 and the head 36. At a predetermined high speed of the rotor, the weight 32 moves radially outwards between guides and when washer 41 contacts portion 12, the spring 43 contacts collar 44 on head 36 to cushion the impact of the head 36 with portion 12. The portion 12 connects together two end portions 10, 11 of a shaft having bearings 7, 8, 9, the outer dust-proof housings 4 of which are secured by bolts 6 to transverse channel members 3 joined edge to edge and connecting the longitudinal side members 2 of the screen. The shaft is coupled to a driving pulley 25 by flexible couplings 19,21. The Specification as open to inspection under Sect. 91 comprises also an unbalancing system, Fig. 6 (Cancelled) and Fig. 7 (Cancelled), comprising a square portion 75 of rotor shaft having a central member 76 (Fig. 6, Cancelled) secured thereto and a movable member consisting of piece 87 and two side pieces 86 running the length of the square portion and two other pieces 88 one on each side of piece 76 and spaced from pieces 86 by spacing members 89. The pieces 86, 87, 88 are secured together by nuts and bolts 90 or members 86 and 87 may be one piece secured to pieces 88 by bolts 90. When a predetermined speed of rotation is attained by the shaft the combination 86, 87, 88 moves relatively to the shaft, i.e. upwardly in the drawing, compressing springs 83 disposed in pockets in members 86, the amount of movement 89a (Fig. 7, Cancelled) being limited by spacers 89. This subject-matter does not appear in the Specification as accepted.

Abstract: 435,760. Furnace grates. FILMA BURNERS, Ltd., and MARSDEN, A., 68, Victoria Street, Westminster. March 21, 1934, No. 8900. [Class 51 (i)] In a solid-fuel fired furnace in which the fuel is moved through the furnace by the rocking or tilting of alternate firebars, the bars are actuated by a motor comprising a cylinder having a piston which is actuated by fluid admitted to the cylinder under the control of valve mechanism electrically operated from a clock so that the sets of bars are rocked at definite time intervals. As shown, alternate bars 3 are adapted to be raised or tilted by means of arms projecting downwardly between a pair of push rods 6 connected to a crank 9 which is rocked by a two-armed lever 11 connected at its ends to the pistons operating in cylinders A and B. Similarly the bars 4 are actuated by another push rod coupled with the pistons in cylinders C and D. The inlet or outlet of pressure fluid to or from a cylinder is controlled by inlet and exhaust valves each normally held in either the open or closed position by a spring but adapted to be moved to the other position upon the energizing of an electromagnet. Normally all the bars are in the lowered position and are maintained in this position by pressure fluid from a circulating pump 38 which is admitted to the cylinders B and D by way of inlet valves B1 and D1, the corresponding exhaust valves B2 and D2 being closed. At the same time cylinders A and C are open to exhaust but closed to the supply, all the valves being held in the normal positions shown in Fig. 3, by springs. A controlling clock (not shown), rotates a shaft 40 carrying cams 41, 42 adapted to engage spring contact fingers 43, 44. The closing of the contacts 44 energizes the electromagnets 51, 49, 45, 46 associated with the valves A1, A2, B1, B2 respectively, which control the cylinders A and B so that the pressure fluid is admitted to the cylinder A and exhausted from the cylinder B. The bars 3 are then rocked to discharge the fuel thereon on to the adjacent bars 4. Similarly the closing of contacts 43 by the cam 41 serves to rock the bars 4. Preferably the shaft 40 rotates once every six minutes and the cams 41 and 42 are so located relatively that the bars 4 are actuated two minutes after the actuation of the bars 3.
