ELECTROCHEMICAL ASSESSING METHOD OF LOCAL CORROSIVENESS ON MATAL SURRFACE

METHOD AND APPARATUS FOR PRODUCING SMOKED FOOD

Prepn. of organo-tin mercapto cpds. - for use as stabilisers in chlorine-contg. polymers

Magnetic recording head with angled working gap - dimensioned so that edges of adjacent tracks have opposing magnetisation allowing narrow spacing

Electrode for spark erosion machine tool - has axis of blank inclined with respect to electrode to avoid need for slight taper

Measuring circuit to determine complex variable - computes complex coupling resistance between two aerials of equal internal resistance

Mobile cooling chamber e.g. refrigerated van - uses electric liq. as low-temp. accumulator, contained in dimensionally deformable e.g. plastics film, receptacles

Cap type seal for boiler pressure union - is single forging with tapering sidewall and internal tongue on base

Machine or engine air duct sound insulation - has walling made solely of foamed plastic, pref. polyether or polyurethane

Steel jacketed heating boiler - has water inlet at front, near outlet connection above fire-box and flue

Fixed program changer for telephone PBX - has settings which are transferred to inserted adaptor, with unit readjusted and returned

Reinforcement of glass fibre for concrete castings - is fibre strand embedded in synthetic resin-filled, flexible hose

Make-and-break spark plug - has induction coil whose field rotates middle electrode about long axis to break short circuit between middle and earthing electrodes

Hollow microwave guide for image-line junction - has horn radiator flare on hollow waveguide sided end, to reduce low transmission loss

Stackable pastry packaging foil - with conical pillars between cells fitting in dimples of next higher foil

HV instrument transformer bushing, or terminal closure - incorporates current transformer operating tripping relay in event of earth fault

Controller for small commutator motor - incorporates several series chokes to limit fault current levels to safe value

Electronic power DC switch - has HV resistant transistor and thyristor controlled by ignition and blocking pulses

Reception bunker for rubbish partic. from waste water screens - drains and cuts up the rubbish for compost or incineration
