Title: Improvements in or relating Luminous Reproductions of circuits
IPC: H02B15/00
Filed: 1928-02-10
Abstract: 288,246. Siemens & Halske Akt.- Gres. April 6, 1927, [Convention date]. Addition to 283,893. Mimic diagrams of distribution networks.-The construction shown in Fig. 9 of the , parent Specification is modified by the provision of opaque shields 7 connected to the opaque separating strips 9 so that each lamp 1, 2, 3 illuminates one transparent strip only. Thus, by including the lamps in the various circuits, the strips can be used to indicate the position of electric wiring and also show which circuits are working. Also in cases where a single line of wire is connected to a 3-phase circuit so as to be energized by the different phases alternatively, each lamp may indicate the reception of current of a different phase from the 3-phase system. Fig. 2 shows a development of this last idea in which lamps 12, 13, 14 of different colours illuminate a single undivided transparent body 11, the colouring indicating the particular phase of current under reception.

Filed: 1966-04-29
Abstract: 1,187,963. Microwave heating. MICROWAVE INSTRUMENTS Ltd. 28 April, 1967 [29 April, 1966; 30 Jan., 1967], Nos. 18955/66 and 4508/67. Heading H5H. [Also in Division G1 Microwave apparatus for the measurement of moisture in a sheet W of e.g. paper or fabric comprises a waveguide 2 having an offset section 8 provided with a slit 12 for the reception of the sheet. The slit extends through the obliquely arranged connecting sections 10 and lies in the median E-plane of the section 8. The upper half of the section 8 is mounted upon pivots 22 incoporating spiral springs (not shown) which press the waveguide half against the sheet. Direct contact between the waveguide halves and the sheet may be prevented by allowing controlled escape of a compressed fluid through permeable membranes arranged over the open sides of the two halves. The compressed fluid may be fed directly into the waveguide section 8 through pipes 102, 104, fluid-tight seals 114 of e.g. polythene being provided in the main wave guide 2. Distribution manifolds may be provided on both halves of the section 8. In an alternative construction, compressed fluid is fed into the hollow sides of the waveguide halves and allowed to escape through perforations in the edges opposite the sheet. The main waveguide 2 may be of hairpin configuration either in the H-plane (as shown) or the E-plane. Several such hairpins may be arranged side by side and the sheet passed through them successively. They are coupled by switching means which enable different combinations to be inserted in series between a generator and a detector. In the arrangement shown in Fig. 7, the split waveguide section 8a is short-circuited at 9 and is connected to a power source through a directional coupler 92. The arms of the directional coupler are connected to detectors 94, 96 for measurement and comparison of the incident and reflected waves. In a further modification (Fig. 6, not shown), the cranked portion is arranged to extend parallel to the edges of an elongated sheet and is connected at either end to transversely extending sections respectively providing input and output.

Abstract: 1,077,023. Winches. FAIREY ENGINEERING Ltd. May 4, 1964 [Feb. 4, 1963], No. 4534/63. Heading B8B. [Also in Division F2] A winch incorporates a disc brake (see Division F2) which is automatically applied to prevent run-away under load when the power supply to the driving means fails or a mechanical failure of the driving means occurs. A cylinder 13, rotatable through a worm-wheel 11 by a worm (not shown) driven through a clutch by an electric motor, has a longitudinal slot 20 through which extends a key 19 connecting a winch drum 17 to a spirally grooved non- rotating spindle 15. During winding the drum 17 thus both rotates and moves axially, the take-off point of the cable 18 remaining stationary. The brake 31, 43, 44 is spring-urged to connect the rotatable cylinder 30 to the fixed structure and is held off during winch operation by a solenoid 69 energized with the driving motor. Signals from an electrical pick-off 80 and a second pick-off associated with the driving motor are compared; on mechanical failure of the winch drive the differing values of the signals causes the comparator to actuate a trip circuit to de-energize the solenoid 69 and apply the brake.

Filed: 1932-02-17
Abstract: 398,525. Supply-meters. FERRANTI, Ltd. and PORTER, G. L., Hollinwood, Lancashire. Feb. 17, 1932, No. 4728. [Class 37.] An alternatinacurrent watt-hour meter driving a demand indicator is adapted to register volt-amperes, by periodically changing the phase angle of the potential supply to the meter, and so varying the relative duration of the successive periods that the average speed of the meter is independent of the phase angle of the load. As shown, an induction disc meter e driving a demand indicator has current and potential coils g, j, the latter being fed alternately, by means of a two-way contactor i, from potential supplies A B, A C obtained from a transformer, and differing in phase by 68‹. The contactor i is driven by a second meter f having a current coil h in the main circuit, and a potential coil k supplied alternately from potentials B D, C D also differing in phase by 68‹. The arrangement is such that periods of increased torque in the meter e correspond to periods of reduced torque in the meter f (and vice versa), and the meter e consequently registers volt-ampÞres. With two-phase, or unbalanced three-phase loads, double-element meters may be employed.
