Title: Device for removing water from large  floor surfaces
Inventor: FACE SAMUEL A JR
IPC: A47L5/34
Filed: 1978-10-19
Granted: 1982-09-07
Abstract: ABSTRACT OF THE DISCLOSURE      Floor or other large surface drying apparatus characte-rized by efficient placement and use within the apparatus of both a vacuum pump and a water pump preferably powered by one prime mover geared to drive both pumps at different speeds.  Vacuum produced by the vacuum pump entrains an air/water mixture and directs said mixture into a plenum chamber disposed in the lower-most portion of the apparatus in order to reduce lift height to a minimum, water being separated from the mixture in the plenum chamber and by means of the water pump, discharged from the apparatus to a remote point through a discharge hose.

Abstract: Abstract The amount of vitamin B12 in solution in a liquid is determined by mixing a sample of the solution with vitamin B12-binding protein from chicken serum in a pH of about 12.8 to 13.2, and then analysing a com-ponent of the mixture. In preferred procedures, especially useful in assaying human sera, a competitive binding technique is employed utilising labelled vitamin B12 and a buffer containing cyanide ion. By operating at very high pH and with chicken serum proteins, the assay can be conducted relatively simply and with very accurate results.

Abstract: ABSTRACT OF THE DISCLOSURE      An auxiliary commutation circuit for an inverter comprises a pair of oppositely charged capacitors con-trolled by separate switches, each operable at a particu-lar time during the conduction cycle of the main thyris-tors to provide additional stored energy for commutation during overcurrent conditions.  A current detector senses the load current and provides a signal to an auxiliary gate whenever the rate of change in the load current or its absolute magnitude exceeds a preselected value.  In response to the overcurrent signal and a timing signal, the auxiliary gate renders the appropriate switch opera-tive coupling the charged auxiliary capacitor in parallel with the primary commutation capacitor so that the com-bined electrical energy stored on both capacitors is available for commutation.  After the commutation period the auxiliary gate maintains the switch in its open state for a sufficient period of time to allow the auxiliary capacitor to be recharged.

Abstract: MANURE SPREADER                 Abstract of the Disclosure A manure spreader having an upwardly opening box-like structure with a beater mechanism at its open rear end through which material may be reduced and thrown from that end.  The conveying mechanism provided in the box-like structure for moving materials to the rear beater mechanism is composed of a fore-and-aft shiftable floor extension that is supported on a fixed floor of the box-like structure.  The floor extension carries a trans-verse vertical push-off wall supported to shift fore-and-aft on the extension.  In a fully extended position, the floor extension is at the front end of the spreader box and the push-off wall is on the front end of the extension.  Manure or material in the box is pushed into the beater mechanism through hydraulic power which first shifts the floor extension rearwardly and in overlying rear position with respect to the fixed floor so that the rear edge of the floor extension is closely adjacent the beater mechanism.          After the floor extension moves to its rear position, the hydraulic power then operates to move the push-off to a rear position so as to move the remaining material into the beater mechanism.
