Title: Selection devices for selcting one of a number of predetermined conditions in response to actuation of an actuator corresponding to the desired condition
IPC: H04N5/44
Filed: 1974-03-15
Abstract: 1469842 Touch responsive switching systems MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 15 March 1974 [28 March 1973] 11615/74 Heading G1N [Also in Divisions G3 and H3] In a selection device in response to selection of one or more manual actuators 10 a pulse generator 1 causes a drive device 2 to operate switch terminals 4 1 -4 16  in a cyclical sequence, gates 21 1 -21 16  are each responsive to corresponding ones of the actuators and the switch terminals and a gate 23 is connected to receive the outputs of all the gates 21 1 -21 16  and is responsive to the first gate 21 which indicates both that its corresponding actuator and switch terminal are actuated so as to halt the drive device at a selected switch terminal. In the channel selector shown touching contact 10 16  controls via a NAND gate 20 and a NAND or AND gate 23 a clockpulse generator so as to start the clockpulse generator. The output from a binary counter 2 causes the output of NAND gates 4 1 -4 16  to selectively become 'O'. When the output from NAND gate 4 16  becomes '0' this causes a change in output of a NOR gate 21 16  which controls via a NOR gate 22 and the NAND or AND gate 23 the pulse generator 1 to stop the clockpulse generator 1. The output gate 4 16  is now selected corresponding to the contact 10 16  touched. This gate 416 connects a potential divider 5 16  to provide a tuning voltage via a diode 7 16  to a varicap diode 8 in the tuner. The arrangement of gates 20, 22 and 23 is such that when a plurality of touch plates 10 are simultaneously touched the selector only selects the channel associated with one of the NAND gates 4 1 -4 16 from which the first '0' output is derived. For example assume that contacts 10 1  and 10 2  are touched while the channel associated with the touch plate 10 16  is received. The clockpulse generator 1 starts and NAND gate 4 1  is selected to provide an output via NOR gates 21 1  and 22 and NAND or AND gate 23 to stop the clockpulse generator even though contact 102 had also been touched. In a modification Fig. 3 (not shown) the binary counter and decoder are replaced by a ring counter (24) and an electronic switching circuit (25). In a further modification Fig. 4 (not shown) the clockpulse generator 1 drives a motor driven selector switch (26) and the touch contacts 10 1  - 10 16  and transistors 12 1 -12 12  and 19 1 -19 12  are replaced by switches (27 1 -27 12 ). In a modification of this Fig. 5 (not shown) two motor driven stepping switches (28, 29) are used one (28) for determining the stopping point of the selector circuit according to the channel switch (27 1 -27 12 ) selected and the other (29) for connecting the associated tuning voltage from (321-3212) the varactor diode tuner 8.

Patent GB-310035-A (GB)
IPC: F02M37/02
Filed: 1929-04-15
Abstract: 310,035. Coats, H. B. April 20, 1928, [Convention date]. Vacuum apparatus.-Apparatus for raising fuel for an internal-combustion engine comprises a vacuum chamber 14 connected by a pipe 15 to the engine induction pipe and by a pipe 22 to the fuel tank 23. The chamber communicates by pipes 31, 33 and the coupled valves 28, 29 with a feed chamber 11 which is connected by a pipe 12 to the carburetter and by a pipe 45 to atmo sphere. The valve 28 is larger than the valve 29, so that during the suction period in the chamber 14 the valves are held to their seats until the head of liquid in the chamber is sufficient to overcome the differential pressure and open them by acting on the lower face of the valve 28. The fuel then flows into the chamber 11 and air passes through the valve 29 and pipe 33 into tlhe chamber 14 and destroys the vacuum. When the fuel in the chamber 14 has fallen to a certain level, the valves 28, 29 close by gravity, and the cycle begins again. Suction takes place through a large port 20 and a small port 21, and when it exceeds a certain degree, a ball valve 17 closes the port 20 to reduce the vacuum in the chamber 14. The chamber 11 is connected by an overflow pipe 35 and valve chamber 38 to the tank 23. The chamber 38 has two coupled valves 42, 43 of different sizes, the larger one being exposed on its outer surface to atmospheric pressure through the pipe 44, while the interior of the chamber is connected to the suction chamber 14 by the pipe 22. When the liquid in the chamber 11 overflows into the pipe 35, the head of liquid acting on the lower face of the valve 42 opens the two valves, so that the liquid returns to the tank 23 and atmospheric pressure enters the chamber 14 through the pipe 44, valve 43, and pipe 22, and stops the flow of fuel to this chamber. In another form, Fig. 2, the fuel enters a chamber 114 inside the vacuum chamber 113, the chambers being connected by ports 115 and a valve 121 which is coupled to an air inlet valve 119. When the liquid has reached a certain level in the chamber 14, it lifts the valve 121 and 119 and flows into the chamber 113, from which it flows through a valve 123 into the feed chamber 111.

The blank B, which is preferably grooved at the end b<2> to engage the driving member 2<a> its mounted between a headstock 2 and a tailstock 3. The cutter C i s mounted in a frame 5 which is pinned to a shaft 4<b> which can rock about its axis and is mounted in an adjustable tool carrier. Longitudinal adjustment of the shaft 4b and tool carrier is effected by means of a hand-wheel 4h which has a threaded spindle 4<e> engaging a threaded bush inserted in the hollow end of the shaft 4<b>. The cutter-spindle 6 is mounted in bearings 5<c>, 5d in the rocking frame and is driven from a shaft 9<d> through 'bevel-gearing 9<c>, shaft 9, bevel gearing 9<a>, shaft 6r and spur gearing 6q. The bearing 5<b> has segmental teeth 5e engaging a rack-bar 7 which is secured to a bell-crank lever 7e pivoted to a slide 8 which may be traversed by means of a lead-screw 8
. One arm of the bell-crank is maintained by means of a weight 7‹ against a cam 10 which causes the motion of the rack 7 to be continuously varied relatively to the slide 8. In operation, the cutter C is first fed to full depth at one end of the groove to be cut in the blank. The lead-screw 8
 is then rotated and this causes the cutter carrier to be swung at a varying speed about the axis of the shaft 4b, the cutter occuping successively the positions shown in Fig. 4 as it moves over the blank. The depth of the groove will vary at different points along its length, being of maximum depth at points k, l on the centre line and minimum depth at the extreme positions c, d. The cam 10 is arranged so that the pitch of the groove is a maximum at the ends and a minimum at the centre of the groove, Fig. 5. The centre of rotation S of the cutter carrier corresponds with the axis of the rotation of the rocker arm carrying the pin engaging the groove in the completed steering gear. The extent of the rotation of the blank during the cutting of the groove may be varied from 450‹ to 900‹ according to the size of the gear.
