Abstract: Gradient gels for electrophoresis are produced by an apparatus in which a pair of syringes are mounted on a support rack together with cams arranged for synchronous rotation. Cam followers engaged by the cams are linked to the syringe barrels, with each cam defining a distinct spiral path translated by one of the cam followers into a preselected rate or rate profile of volumetric discharge from one of the syringes as the cam rotates. With the rate or rate profile established by one cam being distinct from the rate or rate profile established by the other, a gradient or other variation in composition is obtained when the syringe discharges are combined into a common stream and directed to the gel enclosure for solidification into a gel. The gradient or variation in composition is determined by the cam profiles alone, and is independent of the rate at which the cams are rotated, and of whether or not the rotation is performed in a steady manner. Theapparatus can be readily designed for manual operation with highly accurate and reproducible results.

Title: Temperature and pressure control means for water bed
Inventor: HSIA YU CHUN
IPC: G05D16/20
Filed: 1995-08-22
Granted: 1997-12-23
Abstract: Disclosed is a temperature and pressure  control  means  for water  bed  mainly including a temperature control circuitry and  a  pressure control circuitry.  The temperature control circuitry consists of two temperature detecting elements for detecting  the  atmospheric  temperature  and  the  mattress temperature,  respectivley.   The  detected temperatures are compared  with  each  other  and the resulted value together with a set value from an adjusting circuit are calculated by a  microprocessor to produce a target temperature. When the target  temperature  is  higher  or  lower than the mattress temperature,  a heater is turned on or off, respectively, so that  the  mattress  can be always maintained at a value set according  to the user's preferred temperature even when the heat  dissipation  rate  of  the  quilt  is  affected by the changes  in  the  atmospheric  temperature.   The   pressure control  circuitry  consists of a pressure detecting element for  detecting  the  air pressure inside the air chambers of the mattress.  A signal  representing  the detected pressure is  amplified   and   is   subjected  to  an analog-to-digit conversion  so  as  to  produce  a pressure value.  When the pressure  value  is  higher  or lower than a preset pressure value,  an  air  pump  is actuated to relieve or inflate the mattress,  respectively,  so  as  to  always  maintain   the mattress in a softness most preferred by a user.

Abstract: The invention relates to a method and a device for use in coil pipe operations.  A coil pipe (12) is coiled up on a rotary drum (10) and is fed out/in in relation to the drum (10) by means of a feeding device (14) having a rectilinear, through-going passage for the coil pipe (12).  In order to reduce the number of straightenings/bendings of the coil pipe (12) to a minimum, the drum (10) is disposed in the immediate association with the feeding device (14), said drum (10) and said feeding device (14) being positioned and orientated such in relation to each other that an imaginary extension of the feeding device's coil pipe passage (16) extends substantially tangentially to the outer circumference of the coil pipe coil on the drum (10). This measure reduces the number of straightening/bending strains to one straightening upon the coil pipe's uncoiling and one bending upon the coil pipe's (12) coiling up on the drum.  The drum (10) may be swingable about a horizontal axis (36), in order to compensate for varying coil pipe coil diameter during uncoiling/coiling, so that the tangential directional course of said passage (16) is maintained during the entire uncoiling/coiling operation.

Abstract: A frequency error occurring in a repeater station and a receiving side radio station is determined by using a dummy signal received from the repeater station, and is stored as frequency control data corresponding to the frequency error into a memory.          By controlling a reception frequency based on the stored frequency control data, a data signal received from the repeater station is compensated for the frequency error.  A relatively large frequency error such as the common frequency error occurring in the satellite and the downconverter of the receiving side can be eliminated effectively.
