Title: Vane wheel arrangement with nihard wear plates
Inventor: MALISZEWSKI JR THEODORE VINCEN
IPC: B02C15/00
Filed: 1983-11-11
Granted: 1987-05-26
Abstract: In a pulverizing bowl mill(10), partic. for coal, several vanes(36) are supported on a rotatable grinding table(14) of the mill for corotation.  A converging/diverging orifice(38) is mounted within the mill above the table, to direct air flow towards the mill centre.

Title: Time delay circuit using resistance means
Inventor: CHOI WON-TAE
IPC: H03K5/153
Filed: 1987-11-30
Granted: 1991-03-28
Abstract: The circuit is capable of delaying time without  any  affects of voltage  supply   and   ambient   temperature   variation   to semiconductor element such as memory. This delayer is  implemented by inserting a resistor (22) between logic  gates  (21)(23)  which are CMOS inverter. The node voltage of  (47)  is  decided  by  the resistance value of (22) and thus delay time can be  regulated  by (22). The resistance is placed under the  power  bussing  or  data bussing with insulators instead  of  directly  inserting  resistor between inverters. Therefore the size of the chip can be  reduced, which is another merit. Doped multicrystalline silicon resistor or diffused resistor can be used in the circuit and their size decide pulsewidth of logic gate output signals.
