Title: Carrier for semiconductor wafers
IPC: H01L21/677
Filed: 1978-11-07
Abstract: A carrier having parallel transport channels (25) for receiving semi- conductive wafers (16) has oppositely facing recessed regions (17) extending partially into the transport channels in each of which spring- loaded stop member (29) is pivotally mounted. When the carrier is set down, the members (29), which otherwise project below the carrier, are raised against springs 41, pins riding in cam slots (37) so that as the members (29) rise, they pivot to cause flag portions (33) to block access to the channels (25), so as to prevent spillage of any semiconductive wafers contained in the carrier, when the carrier is picked up. When the carrier is set down on a surface, the members (29) engage and are raised by the surface, causing the portions (33) to pivot to allow access to the channels (25). <IMAGE>

Patent GB-2019590-A (GB)
Title: Camera adapted for automatic and manual focusing
IPC: G03B13/36
Filed: 1979-04-19
Abstract: A camera has an adjustable focus lens (12) and a mode selector switch (SA/M) for selecting manual or automatic focusing. A lens-position switch (Sp) is closed when the lens is in its normal focusing range and is open when the lens is moved to an at- rest position outside the normal focusing range, the at-rest position constituting the lens starting position for an automatic focusing operation. Closure of the mode selector switch and a further switch (S1F) initiates a sequence including acoustic automatic focusing and exposure, followed by automatic return of the lens to the at-rest position. When the mode-selector switch is opened and the camera is manually focused, closure of another switch (S1T) initiates an exposure; thereafter closure of the mode-selector switch will automatically return the lens to the at-rest position and open the lens switch (Sp) connected in series with the mode-selector switch. <IMAGE>

Title: Baths for the infirm etc.
IPC: A61G7/00
Filed: 1979-07-17
Abstract: A bed has a bath portion 10, fig. 2, having a cavity 12 capable of receiving the body of a patient 13. The bath can be filled with water which is circulated through a thermostatically controlled unit 17.

Patent GB-2059568-A (GB)
Title: Burner controls
IPC: F23N1/02
Filed: 1979-09-25
Abstract: Apparatus for controlling the supply of fuel gas and combustion air to a burner comprises valves 1 in the air line 3 and 2 in the gas line 4, operating in conjunction to maintain a predetermined air/gas ratio, a branch line 5 to supply gas to one part of the burner and a pressure relief valve 6 in the gas line 4 through which gas can pass to a second part of the burner. In use of the apparatus, gas passes to the second part of the burner only while the pressure at the inlet of the relief valve is high enough to hold the valve open but the gas supply to the first part of the burner is maintained without interruption. Thus the second part of the burner becomes operative or inoperative as the gas supply is varied and the transition is smooth and progressive. <IMAGE>

Title: Determining the strength of plastics crates
IPC: G01M99/00
Filed: 1980-05-29
Abstract: An installation for determining whether plastics crates 1 having integral handles 4, 5, have become embrittled by ageing processes, comprises a conveyor 2 a rotatable table 6 onto which crates to be tested are moved by a pusher 10. The method of testing comprises clamping the crates in position on the table by means of piston rods 24 and operating a pair of bending force generators 8 comprising hydraulic rams 20 and piston rods 21 with forked ends 22 which grip the handles 4 and bend them to and fro. If the handles break the crate is moved off the table and away from the conveyor by a pusher 27, but if the handles remain intact the crate is returned to service by rotating the table 6 so that the pusher 27 may move the crate back onto the conveyor. The crate may however be subjected to torsional forces or hammer blows. <IMAGE>
