IPC: D06F49/02
Filed: 1982-09-15
Abstract: The invention relates to a rotary washing drying or tumbling machine and particularly to a spin dryer of the type in which an electric motor drives a spinning drum. The spinning drum 22 is in two cup shaped portions 39 and 40 joined at flanges 44 and 42 by spin friction welding. The upper portion 39 of the drum has apertures 43 through which water can flow to the outside of the drum. Portion 49 has at its upper end a balance ring 47 of dense metal or very dense plastics which is attached to the upper drum portion 39 by plastic rivets. The lower portion 40 of the drum is attached to a mounting 21 which is then directly attached to a motor shaft. The two flanges 44 and 42 have cooperating projecting ring and groove features to enable the two drum portions to be brought together and held in precise location during the spin friction welding operation.

Patent GB-2187837-A (GB)
Title: Beam splitters
Inventor: VARNHAM MALCOLM PAUL
IPC: G02B6/28
Filed: 1986-03-14
Abstract: In conventional beam splitters, some of the light passing from the input down each limb of the beam splitter will be reflected from the interface at the end of each limb to pass back to the input, thus forming a form of Michelson interferometer and generating spurious interference fringes. To avoid this, the optical path lengths from the point at which the light is split, to the output optical interfaces are caused to be sufficiently different to avoid the interference effect. When used in a fibre-optic interferometric sensor such as a laser gyroscope, the optical path length difference D should be at least the coherence length of the light source. <IMAGE>
