Title: Improvements in speed controlling mechanism for machine tools
IPC: G05B19/04
Filed: 1945-09-24
Abstract: 602,822. Lathes. JONES & LAMSON MACHINE CO. Sept. 24, 1945, No. 24763. Convention date, Sept. 26, 1944. [Class 83 (iii)] [Also in Group XXIV] A speed control mechanism for machine tools comprises a number of speed change devices electrically actuated by sets of selective switches and a master switch for each set, means being provided for operating the master switches serially. As applied to a turret lathe, the cutting speed of each tool is pre-selected and is operative automatically on the presentation of each tool to the work, the feed of the crossslide being controlled by similar gear-change mechanism. The feed-shaft 18, Fig. 1, drives the turret and cross-slide through similar gearboxes 17 and 24 operated electrically from the turret lay-shaft 8 in conjunction with the master-switch box 9. The lay-shaft 8 carries an eccentric 30, Fig. 4, which, on being rotated by the turret, successively contacts masterswitches, such as 31a, whereby the electrical circuit for the particular tooling operation is closed, causing solenoids to move gear-shifting levers, shown in Fig. 5, according to an electrical pre-selector box. The levers 80 and 90 are each shiftable in this embodiment to three positions giving a selection of nine speeds on the output shaft 70. The electrical control is illustrated in Fig. 11, wherein a spring-loaded contact push-button 105, on being depressed, displaces a bus-bar 102 against spring pressure at 103, the taper nose 108 of the stem engaging and passing through a slot in the bus-bar which regains its normal lateral position by virtue of a notch in the stem, whereby the push-button is locked in its depressed position. The stem is also brought into contact with a stationary bus-bar 115, the two bus-bars being connected to the solenoid relays. The displacement of the bus-bar 102 also releases any other speedcontrolling button which may have been previously selected. Nine shiftable bus-bars, each with six push-buttons contacting six stationary bus-bars, thus provide nine selective speeds for each of six successive tooling operations. A similar arrangement providing nine feed and withdrawal speeds to the cross-slide is provided, all controls being initiated from a single control panel on which a lighting system indicates the cutting speed being operated. The masterswitches controlling the cross-slide feed are operated from the lay-shaft 8, Fig. 13, which is grooved to receive slidably adjustable contact members 34, the pegs 33 being inserted as required to feed or reverse the movement of the cross-slide.

Filed: 1971-04-19
Abstract: 1351214 Character recognition systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [26 March 1970] 25029/71 Heading G4R A character recognition system employs two recognition channels which operate according to different techniques. The outputs of the channels are compared to identify the character. The different techniques may be embodied in the character scanner; there may be two scanning devices in the scanner, one photo-electric and the other magnetic for example. Alternatively, or in addition, there may be two processing units which process the signals from the scanner according to different principles. The signals from the processing unit or units are fed to a single recognition circuit or to two recognition circuits operating according to different principles. Where two differing scanning devices are used their outputs may be fed in turn to common processing and recognition circuits whose sequential outputs are compared to identify the character. Where two recognition circuits are used their outputs, each of which may indicate a single character or may be ambiguous, are compared to identify the character. In one arrangement using two processing units and two recognition units, if one recognition unit can not identify the character unambiguously the second processor and recognition unit are enabled, these units operating according to more rigorous criteria than those of the first units.

Title: Hydraulic control system for an automatic transmission
IPC: F16H47/08
Filed: 1970-05-26
Abstract: 1282548 Change-speed control NISSAN MOTOR CO Ltd 26 May 1970 [30 May 1969] 25126/70 Heading F2D An automatic hydraulic control for the clutches 16, 18 and brakes 20, 22 of a three-speed and reverse transmission on a motor vehicle (shown as the usual torque-converter-driven Simpson planetary gear set), including 1-2 and 2-3 automatic shift-valves 76, 78 and a manual range selector valve 74, selecting ranges D, automatic between all ratios; II, invariable second; and I, invariable first if entered from rest, has a separately arranged second-ratio lock valve 84, which engages the second-ratio brake 20 independently of the 1-2 shift valve 76 in range II, and co-operates with the 1-2 valve 76 to release the second brake 20 in range I. In the prior art, the 1-2 shift-valve 76 and second lock-valve 84 have formed a single unit performing these functions. Their separation, by this invention, reduces the effective mass of the 1-2 valve spool, which results in a more rapid response to shift signals in the automatic phase. In all forward ranges the manual valve 74 directs regulated main pressure 102 to a line 120, engaging the forward clutch 18, and feeding the 1-2 shift-valve 76. In Drive, D, lines 116, 118 are also pressurized, the former raising the spool of the second-ratio lock-valve 84 (position right, Fig. 2), so that an apply line 138 of the second-ratio brake 20 is fed from a line 136, pressurized from 120 in the leftward (upper, Fig. 2) upshifted position of the 1-2 shift-valve 76. In third ratio the brake 20 is released by direct-clutch engaging pressure 150 supplied by the 2-3 shift valve 78 when upshifted. In manual II range, the manual valve 74 maintains pressure in lines 120, 118, but exhausts 116, the latter cutting feed to the 2-3 valve 78 to prevent upshift, and also permitting pressure 118, acting on a differential land of the second-ratio lock-valve 84, to depress that valve (left, Fig. 2), whereupon pressure 118 is fed direct to the second ratio brake-apply line 138, to apply that brake independently of the 1-2 shift-valve 76. In manual I range, the second-ratio brakeapply line 118 is also exhausted, and pressure is supplied through a line 124 to the 1-2 shift valve 76, which, in its downshifted position (lower, Fig. 2) directs that pressure to the low brake apply line 156. The 1-2 shift-valve 76 is locked in this downshifted position by pressure 156 acting on its left face. Included in the system are the following items, some of which are not described, but are described in Specification 1,277,321 (see abridgment). A two-stage output driven governor 66, 64 supplying governor pressure 130 to the shift valves in opposition to TV pressure 144 supplied by a regulator valve 92 loaded by engine inlet depression, and reduced at a modulator valve 80; a throttle back-up valve 90 exerting a control over the TV valve in manual ranges; a solenoid downshift valve 88; a 2-3 shift timer 86; a main regulator valve 70; a governor controlled servo pressure modifying valve 82 and input driven pump 12.

Title: An improved apparatus for heating or cooling and ventilating buildings and ships
IPC: F24D5/00
Filed: 1919-10-15
Abstract: 158,305. Lanchester, F. W. Oct. 15, 1919. Air, heating and cooling. -A thermodynamic engine is used in conjunction with a heat exchanger for supplying warm or cold air. The engine comprises a pair of cylinders, the pistons in each performing the double function of compressing air on one side and exhausting on the other. The valve arrangement shown in Fig. 4 is preferably used, and in the example shown is operated by eccentrics and mounted between the cylinders. In Fig. 6 the apparatus is shown as supplying warm air. Air entering at P passes into the header M and passes into the valve chest b<3>, Fig. 4, for example, by way of the valve C. Thence it flows through cylinder port a<6>, Fig. 3, into the cylinder A above the piston. At the bottom of the stroke the air, which has been slightly expanded and cooled due to the action of the cut-off sleeve c<6>, Fig. 4, is passed back into the valve chest b<3> which is now open to the compartment b<5> and passing to the heat exchanger Q by way of the port b<9>, is restored to normal temperature, by water for instance, returning through the port b<10> to the compartment b<6>. At this time the valve C<1> allows communication between this space and the space b<8>, whereas the lower element of the valve C closes the aperture between b<6> and b7, so that the returned air passes through b<8> to the lower cylinder port a<5> to the space beneath the piston, being drawn in by the up stroke. At the end of the up stroke the lower cut-off sleeve of the valve C<1> has not yet fallen so that on the down stroke the air is re-compressed to atmospheric pressure, at which point communication is opened between the chest b<8> and the header N. and the warmed air is discharged through the ventilating conduit L. The other cylinder is working similarly but in the opposite phase.. In the modification shown in Fig. 8, the cycle is inverted, air being first compressed, cooled by heat exchange with atmospheric air supplied by the fan U in the exchanger S and ultimately delivered cool by the trunk T. The warmed air from the exchanger passes by the conduit V, and a valve arrangement W permits any desired mixture to be supplied.

Abstract: 763,577. Earth-boring apparatus. UNITED STATES STEEL CORPORATION. Sept. 15, 1953 [May 15, 1953], No. 25519/53. Class 85. In the drawworks of an earthboring rig a driven shaft 14 of a transmission gear can drive a hoist drum shaft 16 either by a drive transmission comprising sprockets 53 keyed to the shaft 14, chains 80, sprockets 78, and clutch 77 or by a drive transmission comprising clutch 57, a shaft 19 co-axial with shaft 14, sprockets 120 keyed to the shaft 19, chains 124, sprockets 81, and clutch 83. The first drive transmission has a higher gear ratio than the second transmission so that the number of forward speeds available is double the number of forward gears, e.g. three 32, 50, 44; 33, 51, 46 and 34, 52, 48, available between the driven input shaft 12 and the shaft 14. When clutch 57 is disengaged an hydraulic brake 126 can act on the hoist drum shaft 12 via shaft 20, sprockets 127, chains 128, sprockets 121 on shaft 19 and then through the second drive transmission. The second drive transmission can, if desired, be removed from the drawwork, the brake 126 then being coupled direct to sprockets 81. Drives to the cathead and sandreel shaft 17 and rotary table R are taken from shafts 14 and 16 respectively. The reverse drive transmission between shafts 12 and 14 form the subject-matter of Specification 763,579 which is referred to.
