Solenoid valve
The Minijet solenoid valve from Martonair is designed for the direct control of small air cylinders or as a pilot operator for larger control valves, and with low power consumption is said to be suitable for use with transistorized circuits. It has a built in rectifier, making it possible for any particular coil to be used with either an ac or dc supply.
The unit has a spring-loaded, clapper-type armature fitted with vulcanized seals. When the coil is energized — it has a nominal power consumption of 2.5W — a U-type magnet raises the armature off the seat moulded in the base, and seals it against a seat in the moulding surrounding the magnet/coil assembly.
The terminal box is of the plug-in type.
The sub-base mounting obviates the need to remove pipe connections when servicing and makes it possible to mount the same basic valve on a variety of sub-bases for different purposes.
The M /1400 model is a single unit with M5 threads in all ports. The DM /1400 is intended primarily for gang mounting — up to six units can be connected together with tie rods and 0rings. The inlet port is drilled right through the sub-base, and has a in. BSP thread each side.
The units can be used in either a normally open or normally closed role, without changing the pipe connections.
Two types of manual override are available — a simple pushbutton version, and a push-twist type with screwdriver slot.
Operating pressure is from 0-10 bar, and a wide range of coil voltages can be supplied. Made by: Martonair, Twickenham, Middx.

Block indicator
Handy-size slide-rules enabling operators to determine how many Drikold blocks will be needed to keep their refrigerated cargoes chilled during transit, are available from ICI.
There are two rules, one for delivery vehicles the other for trunk vehicles engaged on long journeys. For the former the lefthand portion of the slide is used
to set body wall insulation, thic ness, body cubic capacity ar expected number of door opei ings. The number of blocks n quired to keep goods at 40d€ F during an eight-hour day, CE be read on the opposite sic from one of four windows, ear referring to an expected averat external temperature betwec 50deg F and 80deg F.
The other rule for trui vehicles is used in a similar ma ner except that door openir frequencies are omitted, alternative to setting insulatic thickness and body capacity is third scale which is set to ti vehicle heat leak, if known. T1 number of blocks required keep temperature either 40deg F or 10deg F for 24 hou is then read off against tr appropriate expected extern temperature.
