Title: Joining glass to glass - using metal insert and heating the metal by high frequency induction to effect the weld
IPC: C03C27/08
Filed: 1976-02-04
Abstract: Method comprises inserting a piece of metal in the shape of a closed loop between the zones and heating by some method to which the glass is insensitive, e.g. HF induction, the piece of metal being an individual piece and is exposed directly to the regions to be joined. Used for welding glass tubes, of the same or different diameters. Tubes may be butt welded if of the same dia. or welded one inside the other if of different dia. with either the outer or the inner tube terminating in a flange. The volume of glass actually brought to the melting point is limited to that volume strictly necessary to carry out the weld. Consequently, the shape of the glass close to the weld can remain unchanged, the heating time can be accurately controlled, and since the shape is accurately controlled, the shape of the weld can be controlled. Automatic processing is thus facilitated.

Title: Wind driven power generator with aerodynamic blades - has springs countering centrifugal force to give automatic adjustment of pitch
IPC: F03D7/02
Filed: 1976-12-20
Abstract: The impeller of a wind driven generator has two blades. Each is held so that it can rotate about its own axis and move radially in and out of the hub. Centrifugal force tends to pull the blade radially out. It is opposed by two springs so that the actual radial movement depends on the speed of rotation and thus on the wind speed. A fixed pin in the hub slides in a helical slot in the stem of the blade. The axial movement thus produces a rotation which depends on the wind speed. The pitch of the blade is thus automatically adjusted to wind conditions. This prevents overloading and gives a quick start at low wind speeds.

Title: Automatic individual watering of plants - uses partly porous reservoir filled with water which is put in pot with plant
IPC: A01G27/00
Filed: 1977-03-03
Abstract: A partially porous reservoir (1) is emplanted in the soil which is in the pot, near the plant. The upper part of the reservoir which is above soil level, is not porous so as to avoid too rapid a flow of water and it is fitted with a cover (2) to reduce evaporation. The shape of the reservoir may be varied to suit the requirement of the root structure of the plant. If the roots are compact and go deep then a deep reservoir is used. It the roots spread but are shallow then a shallower reservoir will be used. Impermeability of the cover and upper part of the reservoir can be obtained by coating with varnish. Varnish can also be used to vary or control the porosity of the interred part of the reservoir.
