Filed: 1962-05-22
Abstract: 975,980. Photo-electric measuring arrangements. G. BERGSON. May 22, 1962 [May 23, 1961], No. 19731/62. Heading G1A. [Also in Division H3] An electrometer amplifier comprises a first valve 18 receiving its input from a photo-cell 19 connected between grid and anode and a second reference valve 27 receiving a reference potential from a second photo-cell 28 connected between its grid and anode. Loads 25, 32 with shunting capacitors 26, 33 respectively are located in the respective cathode circuits and feed a pair of cathode followers 41, 42 between whose cathodes are connected a microammeter 51 in series with resistor 52 and also a potentiometer 55 feeding recording meter 57. The cathode follower circuit may be balanced by means of a potentiometer 45. According to the invention, while the H.T. supply circuit 10 feeds the valves 27, 41, 42 directly, the supply for the valve 18 is derived from a pair of ganged potentiometers 13,15 which permit of adjustment of the static potential applied to the grid of the valve 42 and hence the zero setting point without alteration of the potential applied to the valve 18. The arrangement is more particularly intended for use in gas analysis and permits of adjustment of the zero point, by means of ganged potentiometers 13, 15 to correspond to the minimum amount present of a gas component being measured, while potentiometer 55 permits of adjustment of the maximum recorder reading to correspond to the presence of the maximum amount of the gas component.

Abstract: 435,584. Draughting-machines. VITASSI, J., 12, Via dei Vignola, Triest, Venezia Giulia, Italy. July 9, 1934, No. 20126. [Class 97 (iii)] Three or more wheels are attached to a ruler by anchoring pins and one or two cords with ends fixed at points remote from the ruler are passed around the wheels so that displacements of the ruler take place at right angles to its length and to an extent equal to the longitudinal movement of a run of the cord lying parallel to the ruler's edge. As shown in Figs. 1 and 2, guide wheels a, b, each with two peripheral grooves are secured to the ends of a ruler g. One length of cord passes from the fixed point p<1> round the upper groove on wheel a, obliquely upwards and over a single groove wheel c with a graduated flange o and over the upper groove of wheel b to the fixed point e<2>. Another length of the same or a different cord passes from the fixed point p<2> round the lower groove of the wheel b under the wheel c, obliquely upwards and over the lower groove of wheel a to the fixed point e<1>. As the ruler moves upwardly or downwardly over the drawing board by parallel displacements, the extent of the latter are indicated by the rotations of the wheel c and the movements of the lengths of cord d between the wheels c and b. Measuring tabs r with Vernier scales are attached to the runs of cord d and co-operate with scales s on the ruler. To enable the device to be used with rulers of different widths two measuring wheels c are so mounted on their base plate that their axes may be adjusted in an arcuate slot to vary the separation of the axes in a direction at right angles to the edge of the ruler. As shown in Fig. 2, a frame k carrying both wheels a and c and a frame k carrying the wheel b are attached to the ruler by screws i and anchoring pins l. Alternatively, the anchoring pins may be at the axes of wheels a and c and the screw may engage a thickened part of the base plate on which the wheels are mounted.

Title: Method of extraction of sulphur and sulphur compounds from blast furnace slag and apparatus therefor
IPC: C04B7/14
Filed: 1951-08-28
Abstract: <PICT:0733916/III/1> <PICT:0733916/III/2> <PICT:0733916/III/3> Sulphur and sulphur compounds (carbon bisulphide and sulphur dioxide are referred to) are extracted from molten slag flowing upwardly or downwardly in a closed chamber, the height of which is the largest dimension, by injecting air and/or other oxygen-containing substances, e.g. carbon dioxide, or finely dividid calcium carbonate or sulphate, into the melt at the base of the chamber, the rate of injection being controlled in relation to the rate of slag flow so that the oxygen introduced is substantially wholly consumed.  Molten slag enters lined receptacle 1 at 3 and is withdrawn at 4, while air enters at 5 and products are withdrawn at 6.  The chamber at the air injection point should be as small as possible, but large enough that the slag flow is not impeded.  The chamber between the air injection openings 6, 7 (Figs. 3, 4) should be rectangular, with the openings arranged in opposite longer sides, say in a plurality of rows and offset relative to each other.  As shown opening 7 is a blast slit, and all openings slope down towards the base of the chamber.  The ratio of the cross-section in square mms. of the injection opening to the periphery in mms. should be as small as possible, preferably 1 : 5.  In an alternative arrangement (Fig. 2, not shown) a riser tube is connected to the slag outlet to reduce the head on the slag bath, and this riser tube may extend above the slag inlet to reverse the flow. The injection openings may be water-cooled (Fig. 5, not shown).

Title: System for heating the operating cab of a machine
IPC: B60H1/14
Filed: 1977-05-13
Abstract: 1518496 Space heating systems KLOCKNERHUMBOLDT-DEUTZ AG 13 May 1977 [26 May 1976] 20278/77 Heading F4U The driver's cab of a machine (e.g. a vehicle) driven by an I.C. engine is heated by a heat exchanger 3 through which is circulated engine lubricating oil branched off from the engine-oil cooler 2 and circulated via valves, regulating and control devices to the heat exchanger 3, the valve &c. arrangement, which includes pressure actuated valves 15, 20, 25 and a manually operated valve 10 for opening and closing the cab heating system, being incorporated in a one piece housing 28 which, together with a housing 4 for the lubricating oil filter is secured to the machine housing (e.g. the I.C. engine), the housing 28 having threaded bores to which are connected the flow and return lines 7, 18 (shown in Fig. 2, as flows 32, 33) conveying the oil to and from the cab heater 3. The flows 30 and 36 in Fig. 2 are those conveying oil to and from the engine and indicated at 7 and 14 in Fig. 1. Fig. 1 shows diagrammatically the system which is pressurized on starting up by the oil pump 6. If the manual valve 10 is opened, the oil pressure in line 7 opens (via line 21) the valve 20 and cold oil flows mainly via lines 21 and 22 to the engine sump 23 bypassing the heat exchanger 3. At the same time, cold oil from the heat exchanger is driven by the oil pressure back to the oil sump 23 via lines 18 and 22. As the oil presure falls (i.e. when the oil becomes heated), valve 20 closes and oil flows through the heat exchanger 3 and returns via lines 18 and 14 to the sump 23. When the manual valve 10 is closed the oil flows through a bypass 13 therein from line 7 to line 14. The normal pressure in the system keeps open the valve 25 but if, with the valve 10 open the pressure falls unduly (e.g. when idling) valve 25 closes and connects the flow and return lines 7, 14 via line 24 so bypassing the heat exchanger 3. Valve 20 may be mounted within the valve 10 (Fig. 4).
