Inventor: GREEN ROY PATRICK
IPC: A47D7/01
Filed: 1989-03-29
Abstract: A convertible cot-cradle comprising two end panels, side panels connected in parallel between the end panels to define a rectangular framework, and a mattress support surface mounted within the framework. The end panels can be connected together by the side panels in either of two configurations, that is a cradle configuration (Fig. 8) in which the side panels are of a first length and a first height and are spaced apart by a first width, and in which the lowermost portion of each end panel which contacts the floor defines a concave surface to enable the framework to rock, and a cot configuration (Fig 5) in which the side panels are of a second length and height and are spaced apart by a second width. The second length, height and width are greater than the respective first length, height and width. The end panels when in the cot configuration contact the floor in a manner which results in a stable non-rocking structure, and are inverted relative to their position in the cradle configuration. <IMAGE>

The data at the second location typically comprises consumer identification data which is read by the supply authorities dispenser equipment (9) when further credit is purchased. Metering equipment (7) wipes location clear of data or otherwise corrupts the data after allowing the use of the commodity up to the value of the credit. Location (3) may have 10 bits per centimetre while location (5) has 30 bits per centimetre. Dispenser equipment (9) provides an erase code for security purposes which differs from the erase code at the first location. <IMAGE>

The drive motor 6 is carried by webs, 5 and the number of impeller blades 7 differs from the number of webs 5. In the case of an impeller diameter at most 60 mm, the fan blades 7 (Fig 7) are irregularly distributed and constructed in such a way that adjacent the outflow end they have a large setting angle of 70 to 90 DEG , and, in a radial plan view on the rotation axis, the curvature of the blades from the inflow-side is initially limited and then becomes more marked towards the outflow-side blade edge. The webs 5 and casing (1) may be integrally formed with a flange 13 and tube (17) (Fig. 1) by moulding, for supporting the bearings for a shaft 12 of the motor rotor. The flange 13 may house commutator components for the motor 6. Various alternative motor and impeller hub constructions are disclosed as are further structural details of the moulded casing.

Title: Method for manufacturing a mask
Inventor: KIM YONG-HYEON
IPC: G03F1/68
Filed: 1990-09-28
Abstract: A method for manufacturing a mask having a phase shift region useful for producing printed circuits comprises the steps of: coating an opaque mask plate (13) and a photosensitive film (15) on a surface of a transparent substrate (11); exposing a predetermined part of the mask plate (13); exposing a predetermined part of the substrate (11) by etching an exposed part of the mask plate (13); forming a pattern region (17) by etching the substrate (11) to a predetermined thickness (d) forming a phase shift region (19) of width (W) by horizontally etching the side of the mask plate (13); and removing the remaining photosensitive film (15). In the method, the thickness difference between the phase shift region (19) and the pattern region (17) can be exactly controlled by the etch to shift the phase of light passing through the pattern region (17) and the phase shift region (19) respectively. The phase shift region (19) is formed as a part of the substrate (11). Accordingly, a long lifetime mask can be easily manufactured. <IMAGE>

Title: Serial accessed memory data output circuit using low operating current
Inventor: SEO SEUNGMO
IPC: G11C7/10
Filed: 1990-12-13
Abstract: In a SAM data output circuit, at the falling edge of a serial counting clock signal SC, i.e., at one and half cycles before the outputting of the data, the data is sensed from a SAM port memory (2) so as for the data to be stored in a first section of a pipeline type two-section buffer. At the falling edge of the serial counting clock signal SC, i.e., at half cycles before the outputting of the data, the data stored in the first section 81 of the two-section buffer is transferred to a second section 82 of the buffer to be stored therein. At the rising edge of the serial counting clock signal SC, the data stored in the second section of the buffer is outputted. This enables data to be sensed at a separate time from (previous) data output, so reducing the peak current demand. <IMAGE>

Abstract: The invention relates to a method for the simultaneous extraction and re-extraction of metal ions or water-soluble chemical compounds, wherein a heavy aqueous phase 3, a lighter organic phase 1 which is not soluble in water and an even lighter, second aqueous phase 2 are arranged in layers one above the other and agitated. The extracted and re- extracted substances are conveyed from one of the aqueous phases into the other aqueous phase. Apparatus for carrying out the method comprises two cylinders 5, 6, separated by hydrophobic plate 4, permeable only to the organic phase. Shaft 16 rotates agitators 15 found on both sides of plate 4. The aqueous phases are introduced via inlets 11, 12 and removed at 7 and 8.

Patent GB-929813-A (GB)
IPC: F16L3/217
Abstract: 929,813. Thermal switches. GRINNELL CORPORATION. May 4, 1961 [Dec. 8, 1960], No. 16159/61. Class 38 (5). [Also in Group XXVIII] In apparatus for controlling the movement of part of a piping system the piston rod 58 of a hydraulic piston-cylinder unit 42 carries a sleeve 80 on which is mounted an arm 82 to which is attached a control rod 84 carrying a pair of switch arms 86, 88 having electrical contacts 116, 118 and a block 90 slidable on a rod 92 provided with stops 94, 96, and slidably mounted in a bracket 98. The rod 92 also mounts a block 100, and blocks 94, 100 embrace a pivoted switch lever 102 engageable with limit switches 106. These latter components operate to turn off the motor 50 and stop operation of the mechanism when the piston 46 reaches predetermined limits of travel so that if in the event of failure of the temperature-controlled switching the piston continues to move upwardly the block 90 will eventually engage stop 94 to move the rod 92 to actuate the upper switch 106 and stop the motor; the lower switch 106 is actuated in a similar manner when the piston moves downwardly and the blocks 90, 96 are brought into engagement. The temperature-control switch 110 includes a pivoted lever arm 122 provided with a contact 120 disposed between the contacts 116, 118 of the arms 86, 88 the arm being moved by a fluid pressure-operated bellows 150 connected with a fluid-filled coil 156 housed in a jacket 160 around the pipe 2. A scale 164 is calibrated in degrees of temperature. When the temperature of the pipe is at room temperature the motor 50 is switched off, and an increase in temperature causes the fluid 162 to expand and move the lever against the action of spring 154 to bring the contact 120 into engagement with contact 118 whereby the motor is started to cause the piston 46 to move in that direction which carries the switch arms 86, 88 downwardly ; the motor continues to run until the contact 118 moves out of engagement with the contact 120 at which point the motor stops to leave the piston 46 and the piping connection point 38 in a new position corresponding to the new and increased temperature. For each subsequent increase in temperature the operation of the switch unit is the same so that there is an intermittent on and off operation of the motor. If the changes in length of the apparatus are not linear with respect changes in temperature, a cam is inserted between the bellows 150 and arm 122 to provide the desired relationship of movement of one with respect to the other.
