Abstract: 1296593 Electronic musical instruments THOMAS ORGAN CO 8 June 1970 27642/70 Heading G5J An electronic musical instrument comprises means for generating tones in response to operation of controls, means forgenerating bass signals bearing a predetermined relationship with the tones generated and a device automatically controlling production of one or more bass tones in a desired rhythmic sequence. In Fig. 1, an output for a note from keyboard 11 passes along a line 12 which goes to two adjacent drivers 13 around the circle of fifths. Hence, each driver may receive two inputs. Drivers 13 can be made to operate under 3 different conditions: if they receive both inputs, if they receive an input for their respective note, or if they receive either input. Outputs of drivers 13 pass to keyers 15 which have their respective root and fifth tone generators 16. Keyers 15 send the root part along line 18 to gate 22, and the fifth part along line 19 to gate 23. These gates pass signals to the bass circuit 28, which passes the signals to the output system 30. The Automatic Rhythm and Control Unit 24 causes the root and fifth parts to be sounded in various rhythmic patterns, alternatively a switch incorporated in the Unit 24 can allow this to be done manually. The scanner 31 is started at rhythmic intervals by pulses on line 34 and provides inhibiting inputs to all but one of the drivers 13 in turn, until one is reached which is receiving an input for its respective note from keyboard 11. A signal on line 29 from the bass circuit stops the scanner 31 at that position and the respective note can sound until the next pulse on line 34 restarts the scanner 31. The gates 22, 23 must operate one at a time, so only one signal at a time must appear on each of the lines 18 and 19. This is achieved as follows: the output system 30 can detect when line 18 and line 19 have two signals and when neither has a signal, and under such conditions a signal is sent along line 41 to squelch the bass circuit and make scanner 31 operate, thus preventing two notes sounding at once. The apparatus of Fig. 1, with switch 42 in the position shown operates when drivers 13 require both inputs in order to operate. If, however, the drivers 13 are made to operate if they receive either input, then switch 42 is switched to its other position, thus splitting lines 18a and 18b and disconnecting line 19. The root part would then appear on line 18a or line 18b, and the fifth on the respective other line. If the drivers are made to operate only if they receive inputs for their own respective notes, then lines 18a and 18b are split by switch 42, and the root part may pass along either line 18a or line 18b. The keyboard 11 can be a pedal keyboard, a manual, a section of a manual, or combination of two or more manuals.

Abstract: 1296985 Vehicle washing apparatus JACO ENG DEVELOPMENTS CO Ltd 31 March 1970 [27 March 1969] 15980/69 Heading B7J An apparatus for cleansing the underside of vehicles comprises a carriage 10 mounted on wheels 11 so as to be movable relative to a vehicle to be washed, which movement allows a number of jets 30 on the carriage 10 to direct cleansing liquid at the vehicle, the jets 30 being constrained to move with straight line motion back and forth on the carriage 10 in a direction transverse thereto. The carriage 10 is hauled in one direction by a cable 12 wound upon a drum 14 which is driven by motor 15 via transmission coupling 16 described in Specification 1,296,984. The jets 30 are supplied with water under pressure by a hose 18 which is paid out from a drum 19 as the carriage is driven by motor 15 and is used to return the carriage 10 when the drum 19 is driven by motor 20. The carriage 10 has a guideway 24 extending transversely thereto, which guideway has rollers or V-sectioned surfaces for constraining a beam 25 to move on the guideway 24 in the direction of arrows B. The beam 25 is coupled by a pivoted lever 26 on the carriage to an air cylinder 27 for reciprocating the beam 25. Each jet 30 has a guard member 32 which is pivoted on the beam 25 so that, if deflected by a part of the vehicle, the members 32 operate valves which reverse the air supply to the cylinder 27. In a further embodiment described with reference to Fig. 2, the beam 25 is driven directly by an air cylinder 35 secured to the beam 25 and having a piston-rod 36 secured to the carriage 10 at 37. Air is supplied via a pipe 38 to a pair of distribution valves 39, 40 mounted on the cylinder 35 and each having a spool by which air pressure to the valves 39, 40 is controlled, the spools being coupled by a rod 42. When air is admitted through valve 39 to displace the beam to the left in Fig. 2, the spool of distribution valve 40 will be located so that the opposite end of cylinder 35 is open to the atmosphere. When the beam 25 completes its stroke in that direction, an abutment 40 of the beam 25 contacts an operating member of the distribution valve 39 so as to move this to an intermediate position in which the air supply to the left hand side of the cylinder 35 is cut off, and due to the coupling 42 the distributer valve 40 is also moved to an intermediate position. Then the operating member moves the valves 39 to a position in which it is open to the atmosphere while the valve 40 will connect the supply of air with the right hand side of the cylinder to begin the reverse stroke. If the guard member 32a contacts a part of the vehicle being cleaned before the stroke is completed, then the member 32a will displace the springs 46 causing one of the abutments 50 to contact the valve operating member. When the valves 39 and 40 cut off both ends of the cylinder 35 to the air supply and from the exhaust, the beam 25 will dwell, i.e. it will continue to move relatively slowly or remain stationary depending upon the design of the valves 39 and 40.
