Patent GB-2046955-A (GB)
Title: Interferometrically controlled stage with precisely orthogonal axes of motion
IPC: G03F7/20
Filed: 1980-02-21
Abstract: A projection lens (26) is mounted between a movable stage and a stationary holder (28) to project an image of a reticle (14) held by the holder onto a semiconductive wafer (12) held by a chuck (22) mounted on the stage. The stage is movable along orthogonal X and Y axes in a horizontal plane to align different regions of the semiconductive wafer with the projected image of the reticle. First and second movable plane mirrors (30, 32) fixedly mounted on the stage for movement therewith are symmetrically disposed relative to the Y axis in first and second vertical planes intersecting one another at the Y axis. Similarly, first and second stationary plane mirrors (36, 38) fixedly mounted on a housing of the projection lens are disposed parallel to the first and second movable mirrors, respectively. As the stage is moved along the X and Y axes, first and second interferometer systems (40, 42) provide first and second measurement signals indicative of the velocities of the first and second movable mirrors (relative to the first and second stationary mirrors) while they are being moved along first and second measurement paths normal to the first and second movable mirrors, respectively. In response to the sum and the difference of these measurement signals, first and second position control circuits move the stage along precisely orthogonal X and Y axes with the Y axis bisecting the angle between the first and second movable mirrors until a predetermined position is reached. <IMAGE>

Title: Reducing heat-transfer through opaque walls
IPC: E04B1/76
Filed: 1980-03-07
Abstract: An enclosure directly exposed to climatic conditions is bounded by wall(s) 1 at least a portion of whose area is opaque. At least a portion of wall 1 is faced on its exterior with a vitreous sheet 2 bearing a surface coating 3 which reflects infra-red radiation of wavelengths > 5  mu m. Coating 3 preferably faces outwards. Sheet 2 may be adhered to the wall 1 by a radiation-absorbing glue layer 6. Fluid circulation pipes 12 may be incorporated in the wall 1. A sheet 7 of glazing material preferably defines a space 5 closed from the external atmosphere. Alternatively, the sheet 2 may be held apart from the wall 1 to define such a space 5. The coating may be doped SnO2 or I2O3, e.g. 1100-20000  ANGSTROM thick. A reflective roller-blind 10, under the eaves, may be lowered to reduce I-R radiation to or from wall 1. A high thermal capacity or latent-heat energy store 14 may be present in a container 13. Wall 1 may be coated with a radiation-absorbing material. <IMAGE>

Title: Shower head
IPC: B05B1/16
Filed: 1981-08-06
Abstract: A shower head which provides a constant and/or a pulsating water spray has a central spray area 16 and a surrounding annular spray area 18 and water can be directed to one or both areas. Behind the central spray area is an impeller 40 which rotates about an axis aligned with the direction of the water spray and which carries means 53 which block a portion of the central spray area, that portion advancing around the spray area as the impeller rotates to give the desired pulsating spray. The water is arranged to enter the impeller chamber 38 in a direction to cause the impeller to rotate and then leave via the central spray area 16. Such a head can be smaller and so lighter because the axis of rotation of the impeller is aligned with the direction of supply of the spray and lighter because the impeller chamber 38 or the chamber 48 for supplying the surrounding annular spray area 18 can be empty when the associated spray area is not in use. <IMAGE>

Title: Fodder additive for the keeping of small animals and a process for the improvement of the meat quality
Inventor: SZUCHOVSZKY ZOLTAN
IPC: A23L27/10
Filed: 1982-04-20
Abstract: A fodder additive consists of at least two different vegetable aromatic substances, optionally compounds contained in other vegetable aromatic substances and/or the components thereof, and optionally taste improvers. This fodder additive is administered to small animals, especially poultry and rabbits, in such a quantity that the animals take up the additive in a quantity of 10-400 mg per kg of body weight. Thus the stale flavour typical for poultry bred in intensive keeping and a possible unpleasant after-taste are eliminated. The meat tastes similarly to that of poultry kept 'free range' i.e., in yards and gardens.

Title: Thermal energy storage medium
Inventor: MATTHEWS ANDREW JAMES
IPC: C09K5/06
Filed: 1983-08-02
Abstract: A thermal energy storage medium comprising a hydrophilic polysaccharide supporting an inorganic salt that is capable of transforming from one phase to a less hydrated phase absorbing latent heat, and releasing this latent heat upon the reverse transformation. The polysaccharide, preferably Xanthan Gum, may be incorporated in concentrations of 0.05% to 3% together with a nucleating agent in order to form a material that transforms when cooled back to the transformation temperature, or in greater concentrations of 1% to 5% without a nucleating agent to form a material that may be cooled below the transformation temperature without transformation taking place, and stored at ambient temperature whilst still storing the latent heat until activated.The medium is gelled in the less hydrated phase and in some embodiments the gel is pseudoplastic thus enabling it to be poured into chambers of an energy storage device, and then regain its original viscosity at rest.
