Title: Double hydraulic operated clutch device
IPC: F16H61/02
Filed: 1957-06-17
Abstract: 844,871. Friction clutches; change-speed control. BORG-WARNER CORPORATION. June 17, 1957 [June 25, 1956], No. 19086/57. Class 80 (2). Two clutches 96, 97, for selectively connecting different ratio gear trains 102, 105 to a common input shaft 1 in a change-speed gear on a motorvehicle, are engaged respectively by pistons 17, 41, energized by pressure-fluid in chambers 15, 16, which, when both clutches are disengaged, communicate with each other through openings 37 in an axially-fixed centre wall 8 closed by one or other of two smaller pistons 27, 51 when pressure is increased in either smaller piston-chamber 65, 68 to engage a clutch. In neutral, a three-position selector valve constantly supplies pressure-fluid, regulated to a low-pressure from the exhaust of an hydrodynamic torque converter driving the gear to both large chambers 15, 16, and small chambers 65, 68, through passages 3, 4 in the shaft and 32 in the small pistons 27, 51. To engage one of the clutches, e.g. 96, the selector valve is moved to supply fluid regulated at a higher pressure through the same passages to the chambers 65, 15 of that clutch whilst still maintaining the same low-pressure supply to the chambers 68, 16 of.the other clutch 97. The corresponding piston 17 moves up to the clutch pack 96, taking with it by snap-rings 19, 43, an axiallyslidable outer cylinder 14 and the other clutch piston 41, opposed by a pre-loaded diaphragm spring 48. Engaging pressure, building up in the small chamber 65, thrusts rightwards the small piston 27, in opposition to a pre-loaded centralizing diaphragm spring 38 stronger than 48, so that an outer flange 28 on the piston 27 closes the communication 37 between the large chambers 15, 16, permitting rapid build-up to final engaging pressure in the chamber 15. Since the chambers are always filled with fluid, engaging action is very rapid and the chambers are in centrifugal balance. Metered cooling fluid is supplied to the clutch packs from their inner chambers 65 through openings 21, 86 and is directed by funnels 85.

Title: Control means for working out a quotient and for finally rounding off the worked-out quotient
Inventor: RANZINGER WALTER
IPC: G06F7/491
Filed: 1969-04-15
Abstract: 1,270,421. Division with rounding. KOMBINAT ZENTRONIK VEB. 15 April, 1969, No. 19284/69. Heading G4A. A division circuit comprises a dividend register, a divisor register, a quotient register, a means for setting a reference mark in the quotient register at a position determined by the number of decimal places required for the quotient, a means for successively comparing the contents of the dividend and divisor registers and constructing the quotient in accordance with the results of the comparisons, a means for shifting the mark in the quotient register after each comparison until the mark reaches an end position in the quotient register, and a means for rounding off the quotient to remove the mark which is activated by the mark reaching its end position. The division is described by the flow chart illustrated in Fig. 4 in conjunction with a numerical example illustrated in Fig. 15. The mark, which corresponds to the decimal digit 5 is inserted in the quotient register c at a position determined by step 1 of Fig. 5. The dividend is then complemented and the divisor and dividend are then added and placed in the dividend register. The comparison at step 5 eventually, in the example, immediately, leads to step 12. If the comparison at step 15 generates " yes " then a 1 is added to the quotient at the position specified by step 16, if " no " then the quotient is rotated one place to the left and tested, step 19, to determine whether the mark is in the end position. If the mark is in the end position rounding is initiated, otherwise the loop is repeated. The rounding off operation involves the addition of a 1 to the mark, step 23, in the quotient so that if the loop is run through 5 times a carry will be generated, since 5 one's have been added to the mark which is 5, and a rounding up will occur. In the example the cycle is not repeated enough times and the division ends without a rounding up, the mark being cleared.

Abstract: 205,581. McHardy, R. H. July 21, 1922. Driving machines.-A controller for mechanism wherein a series of operations are effected by pneumatic motors, for example the movements required in the operation of machine tools such as capstan or automatic lathes, comprises a rotary valve having passages to correspond with the number of motors and so arranged as to actuate each one in turn, by the admission of compressed air to one side of the motor piston and connection of the other side to exhaust, the r¶les of the two sides being subsequently interchanged. The Figure shows a hollow conical valve which may be held on its seating in the enclosing casing by a spring, and is open to a supply of compressed air through a pipe 13. The valve controls a series of pneumatic motors each for example corresponding to one movement of a turret lathe, and each comprising a double-acting cylinder 20 having ports 23, 25 connected by pipes 11, 12 and ports 24, 26 in the casing to a port 34 and a groove 27 in the valve respectively, whereby one end of the cylinder receives compressed air and the other exhausts through a port 28 in the valve casing. In another position of the valve, the port 24 communicates by a groove with another exhaust port 33. Similar ports and grooves are provided for the other motors, and are brought into action by the rotation of the valve. An escapement or mechanical regulator may be provided to regulate the piston speed. Where a prolonged pressure on a piston is required, for example to support a piece of work against a tool or tools operated by other pistons, a circumferential recess is provided on the valve communicating with a port or ports through it. The lower portion of the casing is formed as an oil well, holes 51 being formed in the valve seating by which oil rises into pockets 52 in the valve face; a longitudinal groove 53 allows the compressed air to distribute the oil over the whole face. The upper end of a pipe 43 extends into each exhaust passage to receive surplus oil which the pipe returns to the well.

An installation comprises a plurality of loads each supplied from an A.C. source T L , T N  over leads 13, 14 by way of a triac T. A low voltage is developed from the A.C. source by means of a transformer Tr and rectifying bridge 24 the output of the bridge 24 being used to energize the operating winding 11 of a reed relay R L  when a switch SW, remote from the triac-reed relay assembly A, is closed. Energization of the relay closes contacts 10 to provide a gate signal for the triac T. Thus closure of the remotely positioned switch SW causes conduction of the triac T to supply the associated load. If desired the switch SW may be of the touch operated type in which case a connection 33, shown dotted, is required. Furthermore, the reed-relay may be replaced by a photo-electric device. All the components such as the triacs, resistors, relays &c. are assembled on a printed circuit board and form a central control unit to which are connected all the switches SW by means of flat, low voltage, conductors in the form of adhesive tapes.

A carrier having movement along and about an axis is arranged to grip the spool-case in the loop-taker and a replacement spool-case, to remove the former and discard it, and simultaneously to place the latter in the loop-taker. In the form shown in underneath view, the carrier comprises a bar 10 mounted to slide but not rotate on a spindle 4 parallel to the shaft of the loop-taker 30, each end of the bar being provided with a pivoted gripping device which includes a fork 25 to engage the bobbin latch hinge pin 28, a claw 23 to engage the end 29 of the latch, and a retaining spring 24. A plunger 21 is rigid with a member 15 slotted at 31 to slide transversely of the spindle 4 and formed with a cam surface 14 to move the carrier 10 along the spindle against a spring 13; a ratchet rack 20 pivoted to the plunger 21 is spring- pressed against a ratchet wheel 7 on the spindle, a detent being provided so that successive outward movements of the plunger cause successive half-revolutions of the spindle 4 with the carrier 10, the inward movements of the plunger producing axial movement of the bar 10 without rotation, which is prevented by engagement of one of a pair of holes 16 in the bar with a fixed pin 18. Two in-and-out operations of the plunger 21 are necessary to exchange the spools, the .first causing the carrier to engage and withdraw the spool-case in the loop-taker and a replacement spool-case in any suitable storage device, finally causing rotation of the carrier to place the new spool-case in line with the loop-taker, and the second to place the spool-case in the loop-taker and release it; the original spool-case is dropped into a collecting device during the first rotation. In a modification, suitable cam means may perform the necessary operations for a single actuation of the plunger. The plunger may be actuated by hand, foot, or knee, and hydraulic or electric power may be used. Any suitable means, such as an abutment to render the spring 24 inaffective, may be used to release the spoolcases from the carrier.
