Abstract: 898,549. Skittle alleys. BRUNSWICK CORPORATION. Jan. 11, 1961 [April 11, 1960], No. 1155/61. Class 132(2) In a bowling alley, bowling beyond the foul line is detected photo-electrically by a mechanism in a housing which also contains the foul signalling lamp. On interruption of the light beam incident on a resistive type photo-cell 50, there is a delay caused by discharge of condenser 56 through the coil 55 of a relay, before the relay is de-energized to release latch 60 for pivotal movement about pivot 61 by tension spring 62. Release of spring arm 68 from latch 60 closes contacts 65, 66 and 67 and energizes foul signalling lamp 31, timer motor 71 and buzzer 30. The timer motor 71 rotates cam 73 which engages under arm 69 to open contacts 66, 67 and lift arm 68 back to latch 60. An automatic pin-setting cycle is started by cam 73 engaging arm 82. The delay time may be varied by adjusting resistance 52.

Filed: 1926-01-18
Abstract: 247,163. Krupp Germaniawerft Akt.- Ges., F. Feb. 7, 1925, [Convention date]. Four - stroke-cycle engines; pumps, actuating by separate motors; cylinders, ports and pipes of.- In engines wherein an exhaust turbine drives an air compressor to supercharge the cylinder, the same terminal ports a<1> are used to admit the supercharging air as serve for the exhaust to the turbine. The ports communicate with a flat chamber G through which passes a small ported cylinder H in which a slide valve J reciprocates. A second set of cylinder ports a<2> lead to the exhaust pipe and are connected with the main ports by a recess f<1> in the piston, when the latter is at top dead centre. Inlet and exhaust ripes L, K communicate with the cylinder H. The valve J is driven from the half speed shaft Q through linkage as shown, the shaft being displaced to one side of the cross-head N. The usual inlet and exhaust valves C, D are provided in the cylinder head. The arrangement of shaft Q and linkage as shown drives the valve J so that the ports a<1> are alternately connected to the exhaust and inlet pipes and times the valve so that the ports in the cylinder H are closed when the piston is at the end of the compression stroke, thereby preventing flow of exhaust from the ports a<2> through recess f<1> and ports a<1> into the cylinder. At the end of the exhaust stroke the ports in the valve cylinder are slightly open to allow air to scavenge the chamber G driving the products through the ports a', recess f<1> and ports a<2>.

Abstract: 725,419. Treating exhaust. GENERAL MOTORS CORPORATION. Jan. 21, 1953 [Jan. 29, 1952], No. 1714/53. Class 7 (2). [Also in Group II] For exhaust quenching and purification, water from a tank 11 is sprayed as by a pump 21 and nozzle 18 into an exhaust pipe 17, extracted from the exhaust gases by the centrifugal action of a rotor 26, and returned, as via a trap 34 and bores 54, to the tank 11 for recirculation. The flow passage 36 through the rotor delivers the exhaust gases to a pipe 33 discharging to atmosphere and is partitioned by radial vanes 53 which extend across the trap 34. Each bore 54 may deliver through an individual ball valve (Fig. 3, not shown) biased towards closure by the centrifugal action to maintain a water seal in the trap 34 ; alternatively, the bores themselves may be small enough to maintain such a seal, or large enough to prevent its formation. In Fig. 2 (not shown) the tank 11 is strapped below a horizontal exhaust pipe 17 so that part of the rotor 26 projects radially into the tank to deliver directly thereto. The remainder of the rotor 26 has a cover forming at one end a partcircumferential gutter receiving water from the bores 54 for discharge to the tank 11 and at the other end a volute collecting the exhaust gases from the radially out-turned end of the passage 36 for delivery to a tangentially-directed outlet.
