[Also in Division B7] A service unit for heating the cargo or washing the hold of a vessel carrying oil or dry bulk comprises a vertically disposed tubular structure having its upper end supported at or above deck level and its lower end 19 located at the bottom of the hold, the tubular structure having a series of wash diffusion sections 11, 12, 15, 16 spaced lengthwise along and communicating therewith, nozzles in said diffuser sections, means to feed wash water to said tubular structure and diffusion sections, heating means associated with said tubular structure comprising a steam pipe 30 extending through the structure and diffusion sections, the lower end of pipe 30 passing through the wall of the structure adjacent the lower end thereof and coiled 31 in an upward direction about the structure for at least part of the length thereof, means to feed steam to said steam pipe and a condensate return pipe 36 extending from the upper end of the said coiled portion of the steam pipe. As shown, the tubular structure comprises tubular sections 6, 7, 8, 9, 10 located between diffusion sections 11, 12, 15, 16. A mounting flange 25 is welded to the top of upper section 6, said flange 25 resting on a ring 62 which in turn rests on the top wall 45 of hatch cover 40. The cover 40 contains a service housing 41 within which the head 21 of the service unit is operatively located. Housing 41 includes a wash water compartment 42, a steam compartment 43, and a condensation compartment 44. Wash water is supplied from a main 53 through a flexible connection 59 to compartment 42 where it flows through aperture 39 into the tubular structure and exits at the diffusion nozzles. Steam is directed into compartment 43 from a steam main (not shown) where it passes through a hole in the mounting flange 25 and is guided by an inverted dish part 26 through hole 31 into steam pipe 30. In travelling through coils 31, 33, 35 the steam heats the oil and is in turn condensed. Condensate is led by pipe 36 into inverted dish portion 28 and hence into compartment 44 where it is drained by a pipe (not shown). When dry bulk is being carried the service unit is removed from the hatch cover and installed in a hollow bulkhead (Fig. 2, not shown).

Title: Improvements in electric relay systems
IPC: H04M19/04
Filed: 1927-10-19
Abstract: 296,915. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.), Oct. 19, 1927. Alternating current systems.-Comprises a contact 3 so as close the line L1. The system is rent input and direct-current output, the system being applicable, for instance, to the recording of demodulated ringing current at a carrier-current receiving station. The arrangement is such that so long as the armature A1 is vibrating in response to alternating current received over the line L, the armature A2 is held against the contact 3 so as to close the line L1. The system is selective to a band of frequencies. When the tongue A1 lies against the contact 1, the condensers C1, C2, are charged from the battery B by current flowing through the relay W2, which is consequently energized. When the armature A1 moves to contact 2. the condensers discharge, and the discharge current from condenser C2 operates the relay W2 in the same sense as before, so that during vibration of armature A1 the relay W2 is continuously energized. A current limiting device may be employed to ensure that the current applied to relay W1 be of constant strength. The system is selective to a band of frequencies in the line L, since at high frequencies the armature A1 will fail to vibrate, while at low frequencies. the currents through the condensers C2, will be of too short duration to affect the relay W2. Within these limits, however, the operation of the relay W2 does not 'depend on the duration of contact between the armature A1 and the points 1, 2. The rate of charge and discharge depends on the resistances R1, R2, and in modifications a single resistance may be used, or the resistance R2 may be replaced by a retardation coil. In a further modification (Fig. 2, not shown) the resistances are omitted and the condenser C1 has an inductance and resistance in series with it. The charging circuit is thus tuned to a definite frequency, and the tuning is rendered broad by the resistance. In order that charging and discharging may take place at equal rates the condenser C2 is then made large compared with the condenser C1.
