Title: Improvements in and relating to the detection of electrical leakage
IPC: G01R19/155
Filed: 1933-04-13
Abstract: 418,064. Detecting, indicating, and locating faults; current detectors and meters. GEORGE, C. H. L., 127, Kyverdale Road, Stamford Hill, London. April 13, 1933, No. 11181. [Class 37.] An indicator for small currents, such as leakage currents, comprises a neon or other glow discharge tube having a shunt and a series resistance. As shown in Fig. 2, a neon lamp 11 has a shunt resistance 12 connected across its terminals and a series resistance 13 connected between one terminal and a negative main 15, the other terminal being connected through a switch 16 to an earth connection 17. Leakage current above a certain minimum value determined by the values of the resistances 12, 13 is indicated by glowing of the lamp 11 on closing the switch 16. A variable resistance may be employed for adjusting the value of the current at which the lamp 11 glows, and may be provided with an indicator such as a pointer and scale for measuring the value of the current. In a modification, Fig. 4 the shunt resistance 31 is connected at one end to a tapping on the series resistance 32, 33, so that the part 32 is in the shunt circuit. A resistance 35 may be connected between the other end of the shunt resistance 31 and the neon lamp 34, or this resistance may be omitted. A similar indicator may be connected between the positive main 14 and the earth connection 17, the switch 16 being in the common earth connection. An indicator may be connected between each pole of a two-wire main circuit and earth, each indicator being protected by a current-limiting device such as a five-watt lamp, and similar indicators may be connected across one pole of the double-pole switch of each branch circuit to enable the faulty circuit to be located. Specification 361,013 is referred to.

Title: Improvements in electrically driven clocks
IPC: G04C21/10
Filed: 1941-09-04
Abstract: 550,549. Clocks. DRUMMOND, C. T. Sept. 4, 1941, No. 11304. [Class 139] Striking mechamism.-Comprises a cain on the minute spindle, a pawl-carrying lever co-operating therewith, and a count wheel the rotation of which is commenced by the release of the lever by the cam and continued by oscillation of the lever effected by an' electromagnet in series with contacts coiltrolled by the count wheel. As shown in Fig. 1, a snail cam 2, supported on the spindle 1 of the minute hand, is pressed by a spring 18, Fig. 2, against a collar 17 on the spindle so that it can rotate therewith while its initial position can be angularly adjusted. The cam 2 co-operates with a weighted lever 3 which jumps off the cam rise at the commencement of each hour. The lever 3 carries a pawl 15 that advances a' count wheel 16 one tooth at each operation. The count wheel 16 forms part of a switch mechanism as described in Specification 550,547, [Group XXXVII], and comprises a flange 20 with differentially spaced indentations 21, Figs. 2, 5 and 6, for co-operation with a ball 22 mounted in a plate 23 and held in position by a disc 24 pressed upon by a spring lever 25. The lever 25 carries one contact 26 of a pair of contacts 26, 27 which are closed when the ball is pushed out of an indentation by the action of the pawl 15 on the count wheel. The contacts 26, 27 are arranged in the circuit of an electromagnet 9 which on energisation attracts its armature 8. The armature 8 is operatively connected to the lever 3 which is rocked to advance the 'count wheel step by step until the ball 22 falls into the next indentation whereupon the circuit is open. The momentary energisation of the electromagnet to ensure the step-wise movement is effected by the other contacts in a circuit closed by the swing of the pendulum as described in Specification 549,409. The cam 2 and the count wheel can be modified to effect striking at the half-hours and quarters. The spindle 1 may be driven by a wheel 19 in the manner described in Specification 550,550 or by gearing in known manner. In the case of the usual gearing the cam 2 might release the lever 3 at a critical moment and a striking impulse be thereby lost. To avoid this the cam 2 is replaced by a snail cam 2b Fig. 10, which has a limited movement with respect to a disc secured to the spindle and is adapted to be moved forward to ensure the release of the lever 3 by an arm 35 on the cam 2b engaging a pawl 44 on a lever 39 controlled by a cam 41 on the spindle of the seconds hand. Chimes.-To provide a chime the count wheel 16 has mounted thereon a drum 31, Fig. 9, with the necessary projecting pins 32 for co-operation with contacts 33 in circuit with corresponding electromagnets. At the succeeding quarter hours 8, 12 and 16 chimes are given while the hour striking mechanism as described above is controlled by a snail cam 34.

Abstract: 896,171. Plate heat-exchangers. PARSONS & CO. Ltd., C. A. March 25, 1960 [April 3, 1959], No. 11360/59. Class 64(3) Sheets with oblique corrugations are stacked with the corrugations of adjacent sheets at an angle to one another and with flat portions at the ends of the corrugations interposed with strips, Fig. 1, having triangular protrusions 2 forming spacing sidewalls for the sheets, the portions of the strip between the protrusions being removed subsequently, Fig. 4, to form series of inlets and outlets for heat exchange fluids. There is a staggered arrangement of inlets and outlets as in Specification 823,951. Headers 9 on one side of the heat exchanger each coincide with a row of inlets to one set of spaces between sheets and fluid flows across these spaces to a set of headers 9 at the other side of the apparatus, these latter headers and the rows of outlets with which they coincide being set opposite the gaps between the inlets. The second fluid flows through spaces alternating with those for the first fluid, the inlets and outlets 10 to these being arranged between the headers 9 and these spaces being closed to the headers 9 (as indicated at the right of Fig. 4) because the protrusions 2 are staggered in alternate spaces between the sheets. The position of the protrusions 2 may be altered so that one fluid enters by a header 9 and leaves by an opening 10 or vice versa. Tubes or bolts pass through holes 4 in the protrusions 2 and corresponding holes in the flat edges of the corrugated sheets. The headers 9 are formed from tubes with a length cut away between their ends and welded or brazed to the heat exchanger.

The ground strip 5 is formed with two trough-shaped channels 6 separated by a web 7 of V cross-section, and the edges of the strip may be stiffened by flanges 8 ; the strip may, alternatively, be formed with one channel only or more than two channels. Each trough 6 is provided with a rod 15 which is spaced from the edges of the strip. The cross-section of the rod 15 may be circular or polygonal, and in the latter case, the rod is set with one corner facing outwardly, Fig. 10. The rod 15 may be supported by ears 16 which are bent from the strip; alterwall of the trough and the plane containing the natively, flanges or projections formed on the rod, or washers threaded thereon, are welded to the strip. Other means for supporting the rod consist in welding it to supports pressed from the strip, or arranging it to be embraced by straps which are bent from the strip; in the latter case, the rod may be carried loosely in the straps, or it may either be welded thereto or pressed against portions punched from the strip. In order that nails 20 for securing the ceiling material may bend around the rods 15, they are arranged to taper to a point and are either of flattened rectangular form or D-shape in crosssection. The strips may be suspended by wire loops 3 from horizontal chanel bars 1 ; or they may be anchored in a brick structure by devices which carry expanding heads 29, Fig. 11, to prevent withdrawal after insertion through holes in the brick structure. The strip 5 may also be embedded in the face of a concrete, plaster or other structure, and in this case the flanges 8 have inclined extensions 26, apertures &c. for anchorage purposes. The strip may be bent to form a hollow beam or strut as shown in Fig. 1 so that panelling may be anchored to both sides thereof. As shown in Fig. 3, the ceiling is built up of two layers of paper-covered plaster board 11, 12 the boards of the two layers being disposed with their joints in offset relation. A layer 14 of core-material such as wire-mesh plain sheet metal, apertured sheet metal or heavy cloth impregnated with resin is cemented or stapled in place between the layers of plaster board. The nails 20 which are driven into the nailing ground strip are arranged in pairs at the marginal portions of the boards. The tiles 7 are held in place by helical-fluted nails, ordinary screws, or barbed nails which interlock with the core material 14. These fasteners pass openings 52 of the tiles near the corners thereof.
