Abstract: 1,071,389. Electric meters. R. HOSEMANN and G. BASLER. Sept. 4, 1964, No. 36284/64. Heading G1Q. An electrometer of the kind in which a flexible member such as a filament or leaf is electrically connected to an adjacent rigid electrode and both are surrounded by an outer electrode is characterized by the provision of at least one auxiliary electrode. Such electrode is electrically connected to the outer electrode and situated closely adjacent the flexible member in the uncharged state of the instrument. In an idiostatic arrangement in which the inner and outer electrodes are the only electrodes, the deflection is proportional to the square of the input voltage and provides an unsatisfactory scale: the auxiliary electrode modifies the sensitivity over the lower part of the scale and can make the whole scale quasi-linear or quasilogarithmic. The flexible element 11, Fig. 3b consists of a filament loop attached at its roots to a loop-shaped inner electrode 13 inside a casing which constitutes the outer electrode. The auxiliary electrodes 9 and 10 connected to the outer electrode modify the sensitivity near the scale zero and further auxiliary electrodes 14, connected to the inner electrode, have a further scale-modifying effect; as also does the expedient of making the instrument base in two insulated parts comprising an inner region 12 connected to the inner electrode and a surrounding part integral with the outer electrode: the resulting scale is quasi-logarithmic. A quasilinear scale is obtained from the arrangement of Fig. 5b (not shown) in which, as compared with Fig. 3b, the instrument cover (17) is nearer the apex of the loop electrode (21) and the relative dimensions of the two parts of the base are different. Also, a sloping portion (20) of the outer electrode on its side facing the filament loop replaces the supplementary electrodes 14 of Fig. 3b. Damping of the instrument may be achieved by magnetizing the auxiliary electrodes 9 and 10 or by filling the casing with an insulating liquid or a gas such as sulphur hexafluoride. Sticking of the filament loop to the rigid electrode loop may be prevented by providing the latter either with a slot through which the filament loop may pass or with a projection preventing substantial contact between the two loops. The interconnections between the various electrodes may be made detachable to allow for use in a heterostatic arrangement such as that of Fig. 8 employing a two-position switch 26 and a double-slide potentiometer 32. In position 1 of switch 26 the arrangement is idiostatic, energized only by the unknown input U M ; but in position II it is heterostatic, employing an auxiliary input U H  to provide selectable different potentials for the electrodes 27, 29, 30, 31.

Abstract: 1,229,014. Incinerators; thermal regenerators; drying sewage sludge; boilers. VON ROLL A.G. 22 Aug., 1968 [4 Sept., 1967], No. 40302/68. Headings F4A, F4B, F4G, F4K and F4U. In a refuse-fired steam boiler installation, Fig. 1, the hot flue gases leaving the combustion chamber 131 are used to heat up a solid heat carrier material, e.g. ceramic pebbles, granulated slag, sand or metal balls, which is circulated in a closed path through interconnected vertically spaced heat transfer chambers 133 and 137. The hot flue gases pass crosswise through the chamber 133 which is constructed with gas-permeable side walls 134. In Fig. 1, combustion air to be preheated supplied through conduit 140 passes through the chamber 137 where it takes up heat from the hot carrier material and is then fed to below the grates as under blast. Carrier material is returned to the upper chamber133 by means of an elevator 146. The hot flue gases from the combustion chamber pass through boiler flue sections 134 and 147 before being discharged via a dust separator 149 and fan 150 into a stack 151. A heat transfer surface 148 is provided in the flue section 147. The gas-permeable walls may take different forms (see Figs. 2-5) and can include tubes (e.g. 56, Fig. 3) which comprise heat transfer surfaces of a steam boiler. In a modified embodiment, Fig. 6, the carrier material, e.g. steel balls, is used to predry sewage sludge. The heated carrier material from chamber 133 flows at a controlled rate down an inclined shoot 163 and is sprayed with sludge from nozzles 164. The sludge which dries on the surface of the hot carrier material is separated therefrom by a vibrating sieve 167, the separated sludge being collected and conveyed to the combustion chamber where it is burnt. Water vapour removed through conduit 169 is introduced into the hot flue gases for destroying odourless substances if present. In a modification (Fig. 7, not shown), the hot carrier is introduced into a rotary drum (182) wherein sludge is sprayed on to it from a coaxially arranged nozzle (184). Helicallyextending strips (185) are provided on the inner surface of the drum to advance the carrier material therethrough.

In a machine having work carriers which travel in a closed circuit, Fig. 1, a number of stations for treating workpieces in liquid have selectively operably devices for providing skip operation, delayed setdown or early pick up of the workpieces. Skip tracks ST1, ST3 permit selected carriers to omit anodic cleaning treatment at stations S2 and S8-S11, while tracks ST2, ST4 permit skipping of acid pickle stations S4-S6 and S13. Early pick up of carriers which have passed through electroplating stations S15-S21 is provided by track ST5 and delayed setdown is provided by devices 22 at stations S29 and S31. Work carriers 52 are guided and supported in horizontal tracks 58, 62 which carry roller chains 68 secured to each carrier, the weight of the carrier being carried by low-friction elements 74 which slide on the track 62. The chains are driven intermittently by gear and motor means 90, 92. Each carrier incorporates a vertically movable work carriage 94 provided with self-lubricating slide members 98 which also electrically insulate the carriage from the remainder of the machine. A work supporting arm 100 is provided with an electrical conductor 104 having a collector shoe 110 for engagement with a bus-bar 112. The conductor may be insulated from the arm 100. An elevator chassis 34 for the carriers 52 comprises a pair of longitudinal members 44 suspended on chains 32 operated by a pistoncylinder unit 36. Each work carriage 94 has an arm 118 which, when the chassis 34 rises, is engaged by a lift pad 120, provided on the chassis. To maintain the lift pads in engagement with the members 118 when the carriers 52 are advanced, the pads 120 are mounted on slide plates 122 connected by roller chains 150, Fig. 4, one of the plates being reciprocated by a cylinder (142), Fig. 9 (not shown). Skip operation.-Assuming a rail section 134 of track ST5 is in the position shown in phantom, Fig. 13, an arm 128 on the carriage 94, when the latter has completed an advancing movement, is supported by the rail section 134 and the carriage remains in the elevated position while supported by the track ST5. With the section 134 raised, the carriage remains supported by the lift pad 120 and normal operation continues. A delayed setdown device comprises a pistoncylinder 158, 156 which, when extended, engages the arm 118 of a carriage to retain the carriage in the raised position, retraction of the piston under the control, for example, of a timer mechanism, then allowing the carriage to be lowered. Early pick up means consists of an auxiliary slide plate 160 which overlies the principal slide plate 122, Fig. 11, and is selectively movable to an operative position by a cylinder (166), Fig. 10 (not shown). A lift pad 164 is attached to the plate 160. In a modification, the motor drive 90, 92 is dispensed with and the transfer movement of the work carriages is achieved entirely by the reciprocating movement of the slide plates 122.
