Patent CA-2049454-A1 (CA)
Inventor: STAMER MICHAEL E
IPC: B41J2/075
Filed: 1991-08-19
Abstract: A microprocessor-based control system for use in ink jet printers periodically measures flow rate of marking fluid, flow time or flight time of marking fluid drops and adjusts the voltage supplied to deflection electrodes to maintain constant character height notwithstanding changes in the printer operating environment that would otherwise result in undersirable variation in character height.  An alternate embodiment uses the flow time, flow rate or flight time information to adjust the charge amplifier gain, rather than the deflection voltage, to achieve the same result.

Title: Auxiliary frame and grid and interaction with mattress periphery
Inventor: PERRY LEROY R JR
IPC: A47C27/06
Filed: 1990-04-09
Abstract: A mattress construction includes upper (11) and lower (12) structures defining generally parallel planes, and coil springs (20) operatively connected to such structures and located between those planes, and with: a) at least one of the upper (11) and lower (12) structures including a first grid (22), b) and band apparatus (26) extending at the periphery of the mattress and connected with the first grid to interact therewith and transmit force for tensioning the grid. The mattress construction also enables treating of a patient having a spinal condition for which traction is recommended by suspending the patient's body to extend generally horizontally on a "trampoline" grid mattress surface which interacts with the mattress border perimeter structure to create a surface lift and therefore stretch reflex on the patient's body. This surface lift is transmitted vertically in a rebound proportional to the weight and movement of the body or bodies on it to further transmit forces horizontally to the perimeter border surface and substructures creating an elongation and decompression of the patient's spine.

Title: Nucleation of ice
Inventor: GROUT BRIAN W W
IPC: C12N5/073
Filed: 1990-08-13
Abstract: The undercooling of an aqueous medium (and therefore damage to a biological sample in the medium) can be minimised by inducing ice nucleation in the medium using cholesterol having a crystal structure which may be obtained by crystallising from methanol and/or acetic acid. Such crystalline cholesterol can be added to the cryopreservation medium (which may also contain a cryoprotectant) or can be coated onto an inner surface of an ampoule, cryopreservation tube or straw. The cholesterol can also be used to induce ice nucleation in the atmosphere to create hail or snow or artificial snow in aerosols of the aqueous medium for use on ski slopes.

Title: Y/c separation circuit
Inventor: UGAKI HIDEHIRO
IPC: H04N9/78
Filed: 1992-04-29
Abstract: A Y/C separation circuit includes a glass delay line for delaying an input composite video signal. A luminance signal and a chrominance signal are separated from each other by an adding circuit and a subtracting circuit each of which receives the input signal and an output signal from the glass delay line. The output signal from the glass delay line is phase-shifted by a 90° phase shifting circuit and then inputted to a multiplier which further receives the input signal. The multiplier outputs an error signal according to a phase difference between color burst signals included in the both signals, and a control voltage according to the error signal is outputted from a low-pass filter. The control voltage is applied to gyrators which terminate an input and an output of the glass delay line, respectively, whereby an inductance value of each of the gyrators is controlled by the control voltage such that a delay time of the glass delay line can be exactly adjusted at one horizontal period.

Abstract: An accessory (10) for a blender includes a generally cylindrical handle portion (11), a generally cylindrical plunger portion (12), and an enlarged circular stop disk portion (13) between the handle portion (11) and the plunger portion (12). The plunger portion (12) is received within a pitcher portion (14) of the blender through an aperture (21) in the cover (15) of the blender.    A mixing blade assembly (24) is positioned near the bottom of the pitcher portion (14) and the length of the plunger portion (12) is such that when the stop disk portion (13) rests on the cover (15), the bottom of the plunger portion (12) is just above the mixing blade assembly (24). An air channel defining member, shown in the form of a bearing housing (23) of the mixing blade assembly (24), would normally cause an air channel to be formed in the fluid (F) in the blender ultimately forming an air pocket around the mixing blade assembly (24). However, the plunger portion (12), which is preferably of a diameter approximating that of the bearing housing (23), prevents the formation of the air channel and ultimately any air pocket.
