Title: Sequence counter
IPC: H03K23/74
Filed: 1960-08-24
Abstract: 913,540. Counting-apparatus. HAGAN CHEMICALS & CONTROLS Inc. Aug. 24, 1960 [Jan. 20, 1960], No. 29302/60. Class 106 (1). In an arrangement for actuating a plurality of relays in sequence, the relays are connected alternately in two groups and each relay has a setting and a resetting coil. As described for counting the revolutions of a rotating shaft, a counting chain comprises ten polarized relays RL-0 to RL-9, each having a setting coil SC and a resetting coil RC, the relays RL-0, RL-2 &c. being connected to a line 14 and the relays RL-1, RL-3 &c. to a line 15. A cam on the rotating shaft (not shown) causes a terminal IT to be earthed momentarily once per revolution. A control unit 32 comprising polarized relays RL-11, RL-12 supplies terminals T11, T12 connected to the lines 14, 15. Initially, a positive potential supplied to a terminal T-10 energizes, over contacts 33, 34 of the relay RL-12, the setting coil SC of the relay RL-0 so that, over contacts 13, 11 of the relay RL-0 and contacts 12, 11 of the relays RL-1 to RL-9, a lamp 17 and output terminal OT-0 are energized by connection to an earthed terminal T4. When the terminal IT is first earthed by the cam on the rotating shaft, the coil SC of the relay RL-11 is energized from the terminal T-10 to change over the contact 33 of the relay RL-11, thereby breaking the circuit to the coil RC of the relay RL-12 and completing a circuit to the coil SC of the relay RL-12 which relay is therefore energized to connect positive potential from the terminal T-10 to the terminal T2 and hence to the relays RL-1, RL-3, &c. Only the relay RL-1, whose coil SC is earthed over the terminals 13, 11 of the relay RL-0 is, however, energized, the relays being of the make-beforebreak type. The terminal OT-1 and associated lamp 17 are thus earthed and the terminal OT-0 is disconnected. In this manner, the relays RL-0 to RL-9 are successively actuated. When the relay RL-9 has been actuated, a terminal T5 is earthed, thereby energizing the reset coils RC of the relays RL-0 to RL-8. The counter may be reset at any time by momentarily connecting terminals T-8 and OT-9 to earth. The output terminals OT-0 to OT-9 may be connected to actuate a typewriter when energized.

Abstract: 314,740. Stanley Automotive Products, Inc., (Assignees of Stanley, E. C., and O'Brien, J. J.). Aug. 18, 1928, [Convention date]. Force-feed lubricators. -- A system adapted to lubricate a number of bearings of a motor-car has a seated tank 14 disposed near a source of heat, such as the exhaust manifold, a main oil line 17 leading from below the level of the lubricant and a minor line 27 joining the main line between a ball valve 25 and the tank. the minor line being employed to lubricate an adjacent bearing. On the application of heat to the tank, the expansion of its contents forces oil through the main and minor lines to the surfaces requiring lubrication. When the source of heat is withdrawn, the partial vacuum created in the tank causes the ball valve to be seated, thus preventing the backward flowing of oil along the main line, whilst the minor line, rapidly emptied of oil, permits entry of air to the tank to restore atmospheric pressure. In a modification, the sealed tank 35 may be connected by an additional line 36, Fig. 6, fitted with a ball valve 39 to a large supply tank 37, so that the defect of pressure in the sealed tank causes oil to flow to replenish its supply. The main pipes may have a pipe cleaner conductor 24 to convey the lubricant. Specification 275,119 is referred to.
