The firm was mainly connected with ebonite and ebonite products.

They manufactured radio components & accessories using ebonite mouldings and, a range of radio receivers & radiograms from 1929 until 1933.

Danipad (Stand 219)

Besides a full range of cut ebonite panels with various surfaces, there is exhibited ebonite tubing, ribbed low-loss formers, rod & wedge rods in many varieties.

Complete coils for popular kit sets are manufactured, as well as HF chokes, ultra shortwave inductances & dual wave-change coils with case switching. There are coil holders, neutralising condensers, wave traps, and switches & bakelised formers up to 7 inches in diameter.

There are in fact very few wireless components required by the amateur that are not stocked by this company. [1]

In September 1930 they displayed a range of wireless sets.

Danipad (Stand 208)

Hitherto Danipad has made a specialty of their 4 guineas Regional Three receiver, but additional receivers, at equally competitive prices, have made their appearance, and the complete range will be seen on this stand. All, by the way, are now available on hire purchase terms.

In addition to the 4-guinea set in a metal cabinet, a 5-guinea Cabinet Three in a wooden cabinet containing all batteries will be seen. Two 4-valve sets will complete the exhibit. One is an upright transportable at to guineas, and the Transol Four, with a sloping panel and the speaker situated above it, at 12 guineas. All these prices include valves. [2]

In September 1932 they displayed a range of wireless sets, radiograms, and Bakelite products.

DANIPAD. (Stand 70)

While essentially ebonite manufacturers producing all forms of sheet and tube, a complete range of components is exhibited.

A new coil styled the Kiloceptor is fitted with internal trimming as well as being totally screened and is intended for use in band-pass circuits or where a number of tuned stages are employed. Slow-motion tuning condensers, all brass built and fitted with knob and dial, are priced at 7s.
A popular type of turntable for portable sets running on ball bearings and being built of Bakelite so that frame tuning will not be affected, sells at 3s.

A wide variety of components is described, in the new season's list available at the stand. A four-valve all-electric radio-gramophone for A.C. or D.C. supply makes its first appearance and employs two screen-grid stages, a power-grid detector, and a pentode output, and is fitted with a moving-coil loudspeaker.

Much interest is being shown in this stand-in-the-home talkie equipment, said to be suitable for use with all types of home cinema equipment. Briefly, the output consists of a flexible shaft coupling between the sprocket wheel of the camera or the projector and the turntable with the recording or reproducing gramophone, so that synchronising is effected. A lead screw geared from the centre of the turntable carries the cutter or pick-up across the aluminium recording discs. Details are obtainable from Cairns and Morrison, of 33, Percy Street, London, W.1. [3]

The company was wound up in late 1933. [4]
