Title: Integrating apparatus
Inventor: NOLTE CLAUDE BYRON
IPC: G01F15/07
Filed: 1967-04-29
Abstract: 1,145,724. Integrating-apparatus. KINGMANN-WHITE Inc. April 29, 1967, No. 19868/67. Heading G1J. Apparatus for integrating a variable quantity (x) with respect to time (t) comprises (i) a cam 96 rotated about the axis of its drive shaft 90 through an angle (#) varying in accordance with a function of the variable quantity (x) (e. g. #= const. x<SP>2</SP> =), (ii) a feeler 100 periodically reciprocated over a variable distance (d) from a predetermined position, Fig. 4b, to a position in contact with the surface 98 of the cam 96, Fig.4c, the distance d being determined by the angle 6 at the instant of contact and by the shape of the cam surface 98 which is a spiral varying in distance from a fixed reference point in accordance with a predetermined function of the angle # (e. g. a linear function so that d = cont. #), and (iii) a counter 190 indicating the total of further movements (a) in linkwork (104, 108, 116, 120) responsive to the feeler movements (d), the former (a) being a predetermined function of the latter (d) (e. g. a = const. #d). The apparatus may be used to integrate the rate of flow of gas measured by an orifice meter with static and differential pressure transducers positioning links 52, 54, acting as inputs to multiplier mechanism 74, whose output link 76 sets the angular position of the cam 96 in accordance withthe product through lever 80 and gearing 82, 88. The feeler 100 is carried by a lateral arm 104 of a striker arm 108 on a pivot 110 and a floating lever 116 is pivoted at its opposite ends to the arm 108 at 114 and at 118 to a lever 120 freely rockable at 122 on the shaft 124 of a ratchet wheel 130. In order to set the predetermined position of the feeler 100, the highest part of the cam surface 98 is brought opposite the feeler 100 which is then moved by adjustment screw 102 into contact with the cam surface 98, with the pivots 114, 118, 122 aligned, Fig.4a (not shown). A battery driven motor 146 periodically gives an eccentric cam 164 a rapid revolution. The cam 164 thus allows the floating lever 116 to drop an amount determined by the angular position of the cam 96 at the instant it is contacted by the feeler 100, Fig. 4c and then returns it to its former position, Fig. 4b. The distances between the pivots 114, 118 and 118, 122 are equal so that the arcuate movement of a pawl 136 at the free end of lever 120 is substantially proportional to the square root of the movement of the feeler 100 each time it is reciprocated. The pawl 136 drives the ratchet wheel 130 and through gears 170, 172, 176, 178, 182, 184, the wheel 130 drives the counter 190 which may be calibrated to indicate directly the quantity of gas which has passed the orifice in a given time interval. To pre-set a clockwise limit to the rotation of the cam 96 to coincide with zero flow, when the output product of the mechanism 74 is zero, a set screw 198 on a slide 196 adjustable on the link 116, is arranged to rest on a semi-cylindrical pin 194 extending from the side of the cam 96.

In a garment press having a pivoted head which is brought down into pressing relation with a fixed hollow perforated buck, a vacuum control valve 36 is employed to control air suction through the perforated buck, a compressed-air-operated device 8 opens the valve 36 in synchronism with the opening of the press, and is furnished with time-control means which controls the supply of air to the device 8 so as to close the valve 36 after a predetermined interval, which is independent of the speed or duration of the opening movement of the press. Press actuating means. The head may be brought down by delivering compressed air through a main control valve 3 into a press operating cylinder 1 whose piston 2 is mechanically connected to the press head. By raising a lever 6 an exhaust valve 9 is closed and an inlet valve 10 opened to deliver compressed air from a supply pipe 4 to the cylinder 1 and close the press. When the piston 2 has passed a port 12 air is passed to a locking piston device 5 to push its piston and rod 13 outwardly, against an arm 14 on lever 6 thereby freeing the operator's hands. Air pressure is also applied to a piston 15 in a cylinder 32 of an intermediary valve 7 so as to open an exhaust valve 16 and close an inlet valve 17. The reverse takes place when piston 15 is relieved of pressure. Suction applying means. The device 8 comprises a pair of pistons 20, 21 carried on a common piston rod 22 and working in bores 18, 19 of different diameters. When compressed air enters at 24 (on removing pressure from piston 15) piston 21 is moved downwardly and rod 22 opens the valve 36 through a connection 37. Chambers 25, 26 on opposite sides of the piston 21 are connected through an adjustable needle valve 28 which can be set to give a predetermined leakage. When the pressure on each side of the piston 21 is equalized the balance of pressure acts on the smaller piston 20 and moves the piston assembly and rod 22 upwardly, thereby closing the vacuum control valve 36. The needle valve spindle may have a pointer moving over a dial graduated in time intervals. With the parts in the positions shown in Fig. 1, the device 8 has been exhausted through the device 7 owing to the pressure in cylinder 1 which is pressing oh the piston 15 while also keeping the press closed. When valve 3 is operated to close the inlet valve 10 and open the exhaust valve 9, the piston 2 moves inwardly, the press opens and simultaneously the valves 16 and 17 close and open respectively, feeding the device 8, which opens the vacuum valve 36 and, after a predetermined interval, closes it again, as set out above. Multiple working. Fig. 2 (not shown). A plurality of presses are arranged so that closure of one press opens another press and also opens the vacuum control valve of the other press in synchronism therewith.
