Storage tank type hot water preparer - has heating element slidably mounted on protective guide tube extending vertically throughout container

Waveguide with flange joints absorbing tension and compression - has alignment spindle with indentations and cavities fitting matched surfaces at interface

Twisting or spinning whorl bearing - is provided with thermal insulation to control temp. distribution and heat transfer to maintain radial play at constant value

Crane with tubular tower - has tower welded direct to side webs of transverse box girder to reduce material and labour costs

Circuit for curve display on visual viewing screen - has comparison and anti-valence circuits enabling closed curves to be presented

Reciprocating piston IC engine in V=formation - has pistons moved by rotary face cam disc on shaft with axis bisecting cylinder vee

Programme selector for TV receiver - has chain of potentiometers in parallel with chain of resistors with tapping for each channel

Portable piston-cylinder unit operated spreader or shears - includes several coaxial valves acted upon singly or in pairs

Plastics snowchain for motor vehicles wheels - comprises links with hooks and eyelets which are held together about the wheel by plastics tensioning cords

Block saw cutting tree trunks lengthways - has aligner on transversely moving raisable block carriage with rotatable clamp

Holder for cables, electric lines, pipes, etc. - with hollow cylindrical tube bearing presser

Improving heat transfer in graphite heat exchange elements - by coating the graphite with viscous resin and embedding electro-graphite in the resin

Storage tank esp. for liquids of low flash point - has double laminated lining with conductive layers earthed

Single swash plate IC engine - has twin crankshafts with bearing pins and toothed planet wheels revolving around sun wheel

Floating oil slick barrier - with floats carrying vertical walls forming an enclosure

Biocidal bromo:acyl-urea derivs. e.g. bromo:acetyl-urea, prodn. - by reacting a urea with bromo:acyl bromide using excess urea as acid binding agent

Heating and air conditioning plant for rooms - has heat pump with heat exchangers outside and inside room

Cooling system for fuel element assembly in reactor - has feed pipe opening at coolant level preventing siphoning

Coating substrate with structured thermosetting resin - applied over active primer layer provided with barrier-forming material sections
