Title: Improvements in work-tables for machine tools
IPC: B23Q35/02
Filed: 1957-10-24
Abstract: 819,948. Workholders. HOWE & FANT Inc. Oct. 24, 1957 [Jan. 16, 1957], No. 33243/57. Class 83 (3). A machine-tool-table for drilling, milling, &c., machines has a pattern plate 28, Fig. 3, attached beneath the worksupport 26, holes 29 in the plate being selectively engageable with a plunger 32 to locate specified positions on the work relatively to the tool. A base 10, Fig. 1, carries parallel guide-rods 16 which pass through ball-bearings 19 of a carriage 17 mounted thereon. The carriage 17 carries guiderods 25 which pass through bearings 27 of a work-support 26. The plate 28 is located on the work-support by pins 30, 31 engaging some of the openings 29, and projecting above the support to position the work. The pin 32, Fig. 3, rigid with a piston 37 in a cylinder 34a of a central boss 35 on the base 10 contains a rod 51, having a flange urged. upwards by a spring 52 to tend to push a ball valve 44 out of the pin. In operation, with work secured to support 26, air is admitted through supply 56 to a chamber 55 in the base 10, to the lower side of piston 37, and if the ball 44 is engaging an unappertured part of plate 28, it is depressed against spring 52 to depress a rod 51 and open a ball valve 48, admitting air through a bore 45 and passages 54 to the cylinder 34a above piston 37. This air can escape by passages 53, 53a to a small space between cylinder 34a and plate 28, the resulting pressure on the top of the piston opposing spring 54 and being just sufficient to hold the ball 44 lightly in contact with plate 28. The latter is then moved to position one of the holes 29 above pin 32, whereupon ball 44 is moved upwards by spring 52 to close valve 48 and cut off the air above piston 37. The air pressure below the piston then pushes pin 32 tightly into the hole 29 to locate the support and work for the machining operation. During this operation, pressure of the tool deflects the guide-bars 16, 25, and the support 28 is depressed until it engages and is rigidly supported by cylinder 34a, the clearance between the cylinder and plate being ten thousandths of an inch. On completion of the machining operation, air is cut off from chamber 55, and spring 54 depresses the piston and pin 32 below the level of plate 28. The support can then be moved to the next maching position. Removing cuttings.-The air which escapes from cylinder 34a through passages 53a blows away cuttings &c. from between the cylinder top and the jig plate 28.

Title: Improvement in parallel knitting machines
IPC: D04B7/04
Filed: 1933-11-28
Abstract: 409,243. Knitting-machines. LUNKE, W., 17, Fitzwarren Gardens, Holloway, London. Nov. 28, 1933, No. 33256. [Class 74 (ii).] A device to be fitted on a parallel machine, comprises an additional pair of beds for sets of needles serving solely to transfer the stitches automatically. The needle grooves are not at right angles to the axis of the machine and their profile causes the direction of movement of the needles to vary, during stroke, in a plane perpendicular to the bed. The supplementary beds 1<a>, 1<b>, are mounted on the upper guiding bars 2<a>, 2<b> of the cam carriage 3. The supplementary carriages 7 reciprocate in grooves 6, and 5<a> or 5b, the last two being cut in the needle covering bars 4<a>, 4b. Each carriage 7 supports a set of cams 8, to operate the transferring needles. The beds 1<a>, 1<b> are secured to the carriage 3, and to bearings 9. As a transfer needle slides forward the part 14 rides upwards on the bar 13, and then slides straight forward, further rise being prevented by a bar 4<a> supported in the needle bed. The dotted line shows the extreme position of the needle. In working, a selected knitting needle KN, Fig. 8f ; makes a complete rise and fall, and at the moment of throwing its stitch ST, a transfer needle TN which tapers to a maximum width at the point 18<a>, Fig. 6, moves forward so that its point goes into the hook of the knitting needle and the stitch falls on to its point 16, and so into its hook 17. The transferring needle TN, slides backwards, placing the stitch in front of a receiving needle RN, which, in making a half rise, goes through the stitch. The transfer needle, while sliding further back, has to pass behind a jack JA, and so leaves the stitch behind on the receiving needle.

Title: Radiated-signal direction finder
IPC: G01S13/42
Filed: 1948-12-29
Abstract: 689,890. Automatic control systems for direction-finders. HAZELTINE CORPORATION. Dec. 29, 1948 [Jan. 30, 1948], No. 33417/48. Class 38 (iv). [Also in Group XL (c)] An automatic control system is employed in a twin-channel overlapping-beam direction-finding apparatus (see Group XL (c)) to maintain equality of gain in the two channels. The apparatus is responsive to reflected signals due to a pulse transmitter, the signals received through the two channels being compared and released when equal in amplitude for display as a bright spot, such as 781, on a plan-position cathode-ray tube display. In accordance with the invention, the gains of the two channels are maintained equal by calibrating signals obtained from a transponder placed a short distance away from the system, the returned signal being received in the normal way and passed through the channels to produce an induction 79<SP>1</SP>. Any inequality in the channel gains results in an angular displacement of the display indications, and any such displacement of the calibration indication 79<SP>1</SP> is detected by one of a pair of photo-cells 101, 102. The cell outputs operate a double throw relay 106 and cause a reversible D.C. motor 109 to rotate the shaft 113 of a potentiometer 114 connected to the automatic gain control conductor 99 of one of the channel amplifiers, in one or the other direction until equality of gain is achieved.

Filed: 1973-07-16
Abstract: 1442682 Multiprocessor computer systems SPERRY RAND CORP 16 July 1973 [17 July 1972] 33681/73 Heading G4A In a multiprocessor system having 2 command arithmetic units one of which 41<SP>1</SP> is shown in Fig. 3, an input/output access unit 46<SP>1</SP> (Fig. 3A) and a memory 40<SP>1</SP>, an interrupt pointer register 56 stores an instruction indicating the route to a command arithmetic unit which an interrupt request signal from, e.g. peripheral device 48<SP>1</SP> is to take, a disable flip-flop 61 locking out an interrupt request whilst a current interrupt request signal is being processed by its associated command arithmetic unit. As described the interrupt signals may be directed to either command arithmetic unit A or command arithmetic unit B or toggled between the two or routed to the command arithmetic unit originating the activity resulting in the interrupt. The interrupt pointer register 56 is loaded in response to an instruction word from memory 40<SP>1</SP> which is decoded in logic circuitry 53 to derive the address at which the storage 40<SP>1</SP> is to be accessed for the 2 bit interrupt instruction which is then entered by interfaces 52, 54 and controller 57 into the register. A subsequent interrupt request is then entered into the interrupt priority network 68. The contents of the register 56 are examined to determine the selected unit, and the state of its disable flip-flop 61 is examined to see if it is re-set. If it is set a retry must be made. If it is re-set an interrupt request flip-flop 76 and the flop-flop 61 are set. The former signals the command arithmetic unit to terminate execution of its current program and to commence an interrupt routine at the termination of which flip-flops are re-set. Routing logic (Figs. 5, 5A, not shown).-In dependence on the states of the stages (160, 161) of the register (56<SP>1</SP>) one of four AND gates (163- 166) is enabled controlling (1) AND gates (175, 176) primed by the output of a flip-flop (190) set in accordance with the unit originating the request and, (2) either directly or via further AND gates (167, 168) primed by interrupt toggle (179), OR gates (169, 170) priming AND gates (172, 173). The AND gates (172-176) control the setting of interrupt request flip-flops (182, 184) and the interrupt disable flip-flops (183, 185). An AND gate (172-176) is disabled if its associated interrupt disable flip-flop is set.

Title: Improvements in or relating to fuel control system for an engine
IPC: F02C9/32
Filed: 1953-12-04
Abstract: 751,016. Automatic engine fuel control systems. UNITED AIRCRAFT CORPORATION. Dec. 4,1953 [Dec. 6, 1952], No. 33765/53. Class 38 (4). In Fig. 1 a voltage, the frequency of which is dependent on the speed of a jet turbine 10, is derived from a tachometer alternator 12 and applied to an A.C. bridge circuit 14 the balance point of which is manually set by a potentiometer 48 to correspond with a desired speed, and a direct voltage corresponding to any speed error is produced and applied to a cross-over network 18. A voltage dependent on jet tailpipe temperature derived from thermocouples 20 is applied to a circuit 22 from which a temperature error direct voltage is applied through an amplifier 24 to cross-over network 18. The two inputs to cross-over network 18 are arranged to be positive for over-speed and over-temperature and negative for under-speed and undertemperature. Cross-over network 18 includes biased rectifiers so arranged that speed or temperature error voltage, according to which is the most positive or least negative, is passed to an amplifier 28 to control the energization of a solenoid 30 operating a control valve 32 regulating the supply of fuel from a pump 38 to fuel jets 36. Since valve 32 cannot be opened unless both speed and temperature error voltages are negative, the valve would tend to remain in its last position or gradually creep to a closed position if tachometer generator 12 failed. To prevent this, a negative bias is applied through a rectifier to the output of the bridge circuit so that the rectifier becomes conductive when tachometer generator voltage disappears and a negative voltage derived from the bias voltage is thereby substituted for the missing speed error voltage to permit functioning of the temperature control. A temperature-variable resistance associated with the air input to the turbine is associated with the bridge circuit and a rectifier so that drop of air input temperature below a predetermined value produces a decrease of fuel. Rectifiers associated with the input to the cross-over limiter prevent excessive overspeed signals, e.g. due to an opencircuited potentiometer 48. Amplifiers 24, 28 are of the type which have their inputs and outputs chopped by switches, e.g. 74, 80, operating synchronously. Power unit 54 for the system derives its power from an external A.C. supply 60 during engine starting but changes over to alternator 12 when a relay 64 is energized automatically at a predetermined speed. Specifications 656,208, 761,003, [Group XXVI], and 751,007 are referred to.
