Title: Improvements in or relating to apparatus for sensing standing bowling pins
IPC: A63D5/04
Filed: 1963-02-13
Abstract: 960,355. Bowling alleys. DOBAN LABS Inc. Feb. 13, 1963 [March 12, 1962], No. 5887/63. Heading A6D. An arrangement for sensing the pins remaining standing on the playing deck of a bowling alley during the course of play thereon, comprises a plurality of flash lamps 28 to 31 mounted above one side of the alley and arranged to operate in turn after each ball of a frame to illuminate successive groups of the array of pins 1 to 10, and a plurality of photo-sensitive devices 44 to 47 arranged above the other side of the alley and positioned to receive light reflected from the heads of standing pins only. The photo-sensitive devices are arranged so that when energized by light reflected from a standing pin, they operate indicators, such as an array of lamps corresponding to the pin array. Electric circuitry is provided whereby, as each lamp flashes in turn, the photo-sensitive devices are automatically switched into operation in a corresponding sequence, so that as lamp 31 operates to illuminate pin 10 only device 44 is operative, as lamp 30 operates to illuminate pins 6 and 9, devices 44 and 45 are operative, and so on. Relays are provided in series with the indicators to keep the latter energized until the end of a frame, and the sensing system is preferably arranged so that its operation is initiated manually at the beginning of a frame, but automatically after the first and second balls of the frame in response to movement of the pinsetter mechanism.

Title: Warning signal devices for use on level crossings
IPC: B61L29/24
Filed: 1926-03-03
Abstract: 248,761. Allabor, W. March 4. 1925. [Convention date ]. Lamp indicators.- A lamp signal for level crossings giving a permanent indication along the railway, and a fixed or variable indication along the road, comprises a screen A presenting a triangular aspect to the roads, with a lantern B carrying an inscription on an opal glass front, which is obscured or rendered visible by means of a shutter between it and the source of light, the shutter being oscillated electrically in conjunction with a pendulum disc P which is normally hidden in a portion D of the casing. The pendulum P and the shutters are oscillated by means put in operation by a train approaching the crossing. A suitable arrangement, not forming part of the invention, is described for operating or controlling the pendulums. The pendulum P is normally held in its concealed position by an electromagnet the circuit of which includes a switch-arm forming a common armature for two opposed electromagnets. A train approaching the crossing closes a track-contact to energize one of the two opposed magnets so as to throw over the common armature and break the circuit of the pendulum-retaining magnet. The pendulum is thus free to swing, and the amplitude of its oscillations is maintained by an intermittently energized solenoid, energized near one end of the swing by a pendulum-carried contact coacting with a fixed contact, the core of the solenoid being pivotally connected with the pendulum. When the train has passed the crossing it closes another track-contact to energize the other of the two opposed magnets, to return the switch-arm to its original position, again energizing the pendulum-retaining magnet.

Abstract: 385,140. Auxiliary - air admission valves. ISDAHL, E. F., 11, Bergens Gate, Oslo, Norway. March 3, 1932, No. 6483. [Class 7 (ii).] The formation of a vacuum in the cylinder during over-run is prevented by an electricallyoperated valve 4 which is opened to admit air to the induction pipe 2 by the closure of a switch 37, actuated by the suction in the pipe 2 produced by sudden closure of the main throttle valve 1. The suction, conveyed by a pipe 39, acts on a diaphragm 42, and current from a battery 24 energizes an electromagnet 6 which in turn attracts an armature 5 attached to the valve 4 ; the vacuum is thus destroyed, and the switch 37 reopened. The valve is held open by a catch on an armature 31 which is spring-pressed into a slot 34, until an electromagnet 32 is energized ; this is effected by (a) a governor-controlled switch 44, when the engine speed is reduced to idling, or (b) a switch 55 which is closed when the accelerator pedal 56 is depressed. In a modification, Fig. 3, two butterfly valves 41 in separate induction passages 31 are mounted on a spindle 58, and rotated against a spring 67 through gearing 66, 65, a lever 62 and a link 61, when the armature 5 is attracted by the electromagnet 6. A catch 75 travels on an insulator 76 and falls into a slot 78 when the valves are fully open this earths, through a wire 53, the windings of the electromagnet 30 which, when energized by the closing of either of the switches 85, 55, withdraws the catch 75 and allows the valves 41 to close. The switch 85 is held open by a relay 79, leads from which are connected to the car dynamo, or the cut-out device, so that it is only energized when a predetermined speed is reached.
