Abstract: 1485661 Reverse gear control DAIKIN SEISAKUSHO KK (DAIKIN MFG CO Ltd) 12 March 1975 [19 March 1974] 10210/75 Heading F2D A single lever fluid-pressure control, for selecting forward and reverse clutches 29, 30 in a motor vehicle or vessel, which provides also graduated pressure control for starting and inching, comprises a forward-reverse select valve 26 and a connected inching valve 21, regulating the pressure supply to the valve 26 in response to loading 28 by the direction control of the valve 26, the valves being arranged in a circuit which provides for economical lubrication supply services 19 for the bearings and torque converters. A pressure-maintaining valve 17, between an engine-driven pressure source 16 and the direction-control and inching valves 26, 21, remains closed to the latter until a predetermined minimum pressure is established in a lubricating feed line 3, which latter includes a one-way restricted control valve 18, which cuts off this supply 3 to the lubrication services 19 when outlet pressure from the control valve 18 is exceeded by an alternative lubrication supply thereafter provided by a drain valve 23, which, in response to increase in pressure 5, 9 regulated to the direction select valve 26 by the inching valve 21, is shifted right by a piston 22, to cut off a drain connection 14<SP>1</SP> from an exhaust line 10 from the inching valve 21 and to substitute therefor a connection to a line 11, which then feeds the lubrication services 19 from the exhaust of the inching valve 21, the control valve 18 being then closed thereby economizing in the lubrication supply. A relief valve 24 limits lubrication pressure. The direction-select valve 26 shown is longitudinally moving and its control actuates a cam 28, having-risers f, r, on each side of neutral, to effect graduated increase in compression of a spring 32 controlling regulation by the inching valve 21, of the pressure in the supply lines 5, 9 to the inching and direction select valves 21, 26. The direction select valve may be rotary and act through a cylindrical cam on the load spring 32 of the inching valve 21.

Title: An Improved Method of and Tool for Continuously and Simultaneously Rough-cutting and Finishing of Gear-wheels according to the Rolling Principle.
Inventor: WINGQVIST ERIK HJALMAR
IPC: B23F21/22
Filed: 1919-04-24
Abstract: 126,291. Wingqvist, E. H. April 29, 1918, [Convention date]. Gear-cutting; milling-cutters.-In cutting spur or bevel gear-wheels on the rolling generating principle, all the gaps are continuously rough cut and finished in a single continuous operation. As applied to the formation of teeth in which the line of intersection of the side surfaces of the teeth and the pitch surfaces form, when developed in a plane A, B, C, D, Fig. 1, congruous parts of parallel cycloids Z', Z<2>, the disk W, Figs. 11 and 12, carrying the cutters Sv, Sx for finishing the tooth surfaces is provided with cutters Fv and Fx to rough out the tooth spaces. If the blank H, Fig. 11, is rolled inwards relatively to the disk W, the cutter Fv which cuts with its outer corner is placed, so as to act first on the blank, at a radius R2 greater than the radius R, at which the cutter Fx acts, which in turn is greater than the radius R at which all the cutters Sv, Sx act. Figs. 11, 12, 13, 15, and 17 show different positions of cutter and blank, but at the same point in the feed, the finishing cutters not yet acting on the blank. Figs. 51, 53, 55, and 57 are similar views when the feed has advanced so that the finishing cutters only are acting on the blank. The angular position of the roughing-cutters Fv, Fx is chosen so that in their paths Z<4>, Z<3>, Fig. 1, they leave a minimum of metal to be removed by the finishing cutters. The number of roughing-cutters should be so chosen in relation to the number of teeth of the gear to be cut that the two numbers have no common factor, and thus all the gaps are acted on in succession, and the feed should be such that this is done by the roughing-cutters before the finishing-cutters begin to act. By using one or other of a pair of disks having 11 and 13 roughing cutters, all gears except that with 11 x 13, i.e. 143 teeth, can be cut. If the blank is rolled outwards, the radii R2, R, are made less than R.

Filed: 1940-06-13
Abstract: 541,882. Impedance networks. ELECTRIC & MUSICAL INDUSTRIES, Ltd., and COLLARD, J. June 13, 1940, No. 10280. Addition to 495,815. [Class 40 (iii)] Errors due to the use of a finite number of sections in the artificial line described in the parent Specification are compensated by the use of a simple power-series formula in spacing the reference frequencies which characterize the sections. That Specification describes a network for either imitating or compensating the attenuation and phase characteristics of a cable or the like, in which a series of sections is designed on the basis of reference (angular) frequencies p 1 , p 2  ... one of which is assigned to each section. The concept of "reference frequency" is defined in the Specification, which prescribes a formula according to which these frequencies are to be spaced apart. The approximation thus obtained is rendered imperfect by the fact that the number of sections cannot be infinite, and Specification 524,907 proposes as a means of improving the approximation, the use of a new distribution formula for prescribing the spacing of the frequencies ; this formula includes a term where r is an integer, cr is a constant, X n  W is the loss or delay to be simulated by the whole group of sections at angular frequency w, p is a variable of which the reference frequencies are particular values, and # is the finite upper limit of p. According to the present invention the above term is replaced by MB +p+ , where Br is a constant.

Filed: 1961-03-21
Abstract: 920,789. Shearing. NYBY BRUKS AKTIEBOLAG. March 21, 1961 [March 22, 1960], No. 10346/61. Class 83 (4). A device for automatically severing a web when a deformed portion thereof approaches a machine which the said portion must not enter, comprises means movable in the direction of motion of the web and feeling the cross-section thereof and severing means located between the movable means and the machine and mechanically connected to the feeding means so that the severing means are operated by engagement of the feeling means with a deformed portion of the web. A web 3 being fed to a rolling mill passes through a guide 2, the internal shape of which conforms to the correct section of the web, and which is movable in the direction of motion of the web against the action of a spring. The guide is mechanically connected to the severing means 6 which comprise two cutters 7 mounted on slides 8 which run on converging guides 9. When a deformed portion of material reaches the guide 2, the guide moves forward and the cutters sever the web. A stop is provided to prevent the cutters contacting each other. In a modification the cutters are mounted on shafts 11 which rotate when pins 12 are contacted by the guide 2. The shafts 11 may have gear teeth and mesh with rack teeth on the guide 2. A shear pin may be provided instead of or in addition to the spring 5. The guide, or some part movable therewith, may co-operate with a signalling device or a control mechanism for the rolling mill.

Title: Improvements in or relating to electronic relay circuit arrangements
IPC: H03K3/04
Filed: 1943-06-25
Abstract: 582,758. Pulse generating circuits. WILLIAMS, F. C. June 25, 1943, No. 10351. [Class 40 (v)] A frequency counter or divider in which provision is made for controlling the duration of wave forms developed by the electrodes of the valve in response to applied impulses, comprises a multi-grid valve, the potentials of the electrodes of which pass through a predetermined cycle of changes in response to an applied impulse and then revert to their initial or stable condition, the cathode circuit including a feed-back resistance and the anode of the valve being back-coupled to the grid nearest to the cathode through a condenser. The arrangement is such that the cathode potential follows substantially that of the control grid and the time interval between the application of the impulse and the reversion to the stable condition is determined by the value of the fixed voltage to which the control grid tends to rise for given values of the difference between the anode and the control grid voltages in the stable condition and by the time constant of a circuit which includes the condenser coupling anode and the control grid. The Figure shows a valve V2 with a cathode load resistance R5 and with the anode and the control grid backcoupled by a condenser C2. The suppressor grid potential in quiescent state blocks the valve by diverting current to the screen grid while the anode and control grid voltages are fixed by the diodes V1, V3. If the cathode of the diode V1 is triggered by a negative impulse the potential of the control grid and cathode fall so that the anode takes current and its potential falls in a linear manner due to the feed-back of the potential to the control grid. When the anode potential approaches that of the cathode, the potential will then rise, following the control grid to which the anode potential is fed back through the condenser. In this way the anode current is again cut off and the valve reverts to the stable condition with the diodes conducting. Alternatively, the input may be a positive triggering impulse applied to the suppressor grid, Fig. 3 (not shown) or a negative triggering impulse may be applied to the cathode of the diode connected to the control grid, Fig. 1, provisional (not shown). The delay may be adjusted by varying the time constant circuit C2, R7, or by varying the initial anode voltage by varying potentiometer P3 or by varying the voltage to which the control grid tends to rise in the quiescent state as by connecting the resistance R7 to a potentiometer connected across the high-tension supply. Output is taken from the screened grid or the cathode according as a positive or a negative wave-form is required. The diodes may be in a common envelope with the pentode.

Title: Improvements in or relating to apparatus for detecting slip between movable members
IPC: B65G43/04
Filed: 1953-04-16
Abstract: 770,951. Endless belt conveyers. GENERAL ELECTRIC CO., Ltd., and SPENCER, P. L. April 14, 1954 [April 16, 1953], No. 10436/53. Class 78 (1). [Also in Group XXIV] Apparatus for detecting when slip between a conveyer belt and its driving roller exceeds a predetermined value comprises two members coupled to the belt and roller respectively and arranged to move at the same speed when the slip is equal to said predetermined value, and means for detecting relative movement between said members when the slip exceeds the pre. determined value. In Figs. 1, 2, the driving pulley 11 of a conveyer belt 10 and a snub pulley 12 engaging the belt are connected through gearings 13, 15 to a disc 20 and annulus 21 respectively, the gearings being such that when a predetermined slip occurs between the pulley 11 and the belt, the disc and annulus rotate in the same direction at the same speed. If the slip becomes greater than this predetermined amount, the disc 20 rotates anticlockwise relatively to the annulus 21, whereby a sprung arm 23 secured to a block 22 on the disc engages a spring-loaded finger 26 pivoted at 27 and is deflected against a contact 25 so as to operate an indicator or shut down the driving motor. If the belt is driven in the opposite direction, the arm will engage a contact 24. Instead of using the gearing 13, 15, the size of the pulleys 11, 12 may be so arranged as to cause rotation of the disc 20 and annulus 21 at the same speed. In a modification, Figs. 3, 4, the gearings 13, 15 are connected to shafts 40, 41 of a differential gearing which, when the slip is equal to the predetermined value, rotate at equal speeds in opposite directions. When the slip exceeds this amount, the differential cage 46 rotates clockwise whereby teeth 47 on the cage engage pawls 52 pivotally mounted on a ring 50, so as to rotate the ring and bring projection 55 into engagement with the actuating plate 57 of a switch 58 and operate a motor control member or provide a warning. The invention may be used for indicating slip between a driving belt and a driven pulley or for indicating when the slip between two elements of a friction drive exceeds a predetermined amount. Specification 719,136 is referred to.
