Inventor: HYMAN OSCAR E
IPC: F04B49/06
Filed: 1992-02-27
Granted: 1996-04-02
Abstract: A linear peristaltic pump for pumping fluid through a resilient tube has a pair of pumping fingers,  a pair of pinching fingers,  and a strain gauge to monitor pressure inside the tube.  The first pumping finger squeezes the tube at a first location, and the second pumping finger squeezes the tube at a second location.   Additionally,  the first pumping  finger  is  configured  and  operated  to  displace approximately twice the fluid volume displaced by the second pumping finger.  The first pinching finger occludes the tube upstream to the first pumping finger and the second pinching finger occludes the tube between the first and second pumping fingers.  To monitor dimensional changes in the outer diameter of the tube and thereby indicate pressure inside the tube, the strain gauge  is mounted on the pump between the second pinching finger and first pumping fingers.  Finally, a leaf spring and photoelectric sensor are associated with the first pumping finger to indicate when the finger is in its fully withdrawn position.

Title: High-frequency heating device employing switching type magnetron power source
Inventor: MAEHARA NAOYOSHI
IPC: H05B6/68
Filed: 1991-07-02
Granted: 1996-07-16
Abstract: A high-frequency heating device (microwave oven) comprises a power converter for converting electric power from a commercial source into high-frequency power.  A step-up transformer has a high-voltage winding and a low-voltage winding.  A magnetron receives the high-voltage and low-voltage outputs.  A resonance circuit is connected in series or in parallel with the filament of the magnetron.  A control circuit controls the power converter such that the operating frequency of the power converter approximately coincides with the resonance frequency of the resonance circuit at the time of activating the power converter. The advantage is to achieve a rapid start of oscillation of the magnetron, while suppressing the high voltage that previously occurred at activation to avoid occurrence of the moding phenomenon.

Title: Method and apparatus for continuous casting of metal
Inventor: GRAHAM THOMAS S
IPC: B22D11/06
Filed: 1993-08-09
Granted: 2005-11-15
Abstract: Electrostatic application of a dusting of dry, electrostatically adherable, thermally insulative powder particles over a workface of a moving mold in a continuous metal-casting machine in which the mold surface or surfaces which provide the workface or workfaces revolve in a generally oval course. A dry dusting of protective powder particles of refractory material is applied to the workface by being dispensed entrained in a plurality of air streams uniformly spaced across a width of the workface. The air streams are deflected toward the workface by a deflector surface, and after being deflected the powder particles are electrostatically charged by suitable electrostatic apparatus prior to contact with the workface. The moving mold having the workface to be dusted is electrically grounded for attracting the electrostatically charged powder particles for adhering them to the workface. The resultant coating formed by the dusting so deposited is remarkably uniform over a substantial area of the workface, a phenomenon explainable by mutual electrostatic repulsion of the dry powder particles being deposited.      Continuously re-applied dusting over the workface during a continuous cast provides an immediately useful repair or replacement of dusting powder lost from the coating on the workface of a revolving mold surface during casting. The dusting may be removed at will from the workface by means of an air knife, and then immediately the workface is coated again by electrostatic application of a dry dusting of the protective powder particles.
