Abstract: 768,440. Electric analogue calculating systems. MINISTER OF SUPPLY. March 3, 1949 [Feb. 19, 1948], No. 4888/48. Class 37. [Also in Group XL (c)] In an aircraft or ship, navigational aid apparatus comprises indicators for deviation of course and for time or distance (R) remaining before the destination (D) is reached, and means for computing (NN + EE),(NE -NE),(N<SP>2</SP> + E<SP>2</SP>) where N, E are co-ordinates for D related to the craft's position and N, E are resolutes of the craft's speed. Resolutes N, E are derived from a sin/cos potentiometer 101, 102 energized by an airspeed analogue voltage and driven in accordance with aircraft heading and applied to amplifiers 105, 106; resolutes of wind velocity being applied at 103, 104. The amplifier output from amplifier 105 drives a motor 107 to adjust potentiometers 109, 110 so that a voltage proportional to N is applied across a bridge circuit 113, 114, 115, 116; ( - N) being fed back at 121 so that 105 is fed in proportion to acceleration. The motor 113 driven by current proportional to N adjusts potentiometers 118, 119, 120 to the new value of N so that the tapping on 118 gives the instantaneous value of NN and so on. The voltage proportional to E is applied from 111, 112 to 119 so that the tapping on this potentiometer provides NE. The voltages NE, NN, EN, EE are so combined in a ratiometer 124, 125, 126, 127 that this device indicates the value of as the departure from the wanted course. By altering connections to 119, 120, 123, 128, 125 the ratiometer device may represent the expression for the time remaining before (D) is reached. In an alternative arrangement, Fig. 2 (not shown), the quantities NN, EE and NE, NE and N<SP>2</SP>, E<SP>2</SP> are combined in high-gain amplifiers before applying them to indicators direct or through an electronic divider or a servomotor.

[Class 102 (i).] An arrangement for controlling a predetermined maximum speed of an internalcombustion engine in which a controlling element situated in the fuel supply system diminishes the effective quantity of fuel supplied upon an increase in pressure difference between two selected points in the fuel supply system. Fig. 1 shows a piston body 31 provided with a throttling passage 32 and integral with the delivery valve 20. Upon an increase in speed, the fuel is stored beneath the piston until the plunger 14 nears the end of its delivery stroke when the stored fuel is byepassed to the suction inlet 17 through grooves 29, 30. Fig. 3 shows the controlling element arranged in the fuel delivery pipe and comprises a piston body 59 provided with a throttle plate 72 and ports 65 aligned with ports 67. Upon increase in speed the piston body is raised against the spring 62 and ports 66 align with ports 68 thus byepassing the fuel to the suction tank 18. Fig. 2 shows a pump for an engine with a plurality of cylinders wherein the delivery valve 20 of one pump cylinder is provided with a cylindrical extension and a throttle plate 49. Upon an increase in speed, the fuel is byepassed through port 50 to a chamber 52 provided with a piston 53 and a throttle passage 54 leading to suction. The piston 53 is connected by a link 55 i;o a rack 48 gearing with all the pump plungers, which are provided with inclined grooves 47 which vary the time of byepassing to suction. The maximum engine speed may be adjusted by varying the loading of the springs or varying the size of the throttle passage. The throttle may be replaced by a Venturi tube.

Abstract: 394,619. Linkwork. ROGER, G., 23, Victoria Road, Macclesfield, Cheshire. Feb. 18, 1933, No. 5033. [Class 80 (iii).] In a torque-transmission mechanism employing centrifugal force for driving purposes, the shaft 1 is driven by a driving disc 6 through a crank arm 2 connected to weighted arms 5<1> .. 5<5> having pin-and-slot connection with the disc 6. The arms, which are driven by the pins 8 in the slots 9, are provided with bowls 14 impinging on the inner surface of guiding means which comprise a divided ring 12 concentrically mounted about the crank pin 3 and connected to pins 18 on arms 16, 17 connected to the crank arm. The lower member of the divided ring is connected by a member 22 to a counterweight which is mounted on a further arm of the crank and is adapted to balance the otherwise unbalanced excess weight of the lower ring member on the right of the pivot 18. The ring member 12 projects from a plate 13 behind which are provided bowls 11 capable of impinging against a rim 15 on the disc 6. The rotation of the plate 13 causes the upper ring member 12 to move outwardly in the neighbourhood of arm 5<2> thus allowing arm 52 to move outwardly to its full extent and apply force to the crank arm when the arm is at rightangles to the crank. Of the other arms, 51 is prevented from affecting the crank pin 3 by pin 8, 53 is prevented from moving outwardly to the same extent as 5<2> by the ring part 12 on the left of the pin 18 and which is now nearer the shaft 1, while arms such as 5<4>, 5<5> are prevented from acting by the lower ring part which does not open due to the effect of the counterweight. In a modification the upper ring part is dispensed with and the lower ring part is fixed.

Abstract: 373,253. Knitting. WELFFENS. E., 490, Wilmslow Road, Fallowfield, Manchester. Feb. 17, 1931, Nos. 5077 and 10942. [Class 74 (ii).] Knitted fabric is rendered inextensible longitudinally or transversely of the stitch wales by providing warp threads 17 which are not formed into knitted stitches and which are held in position by one or more weft yarns on both sides thereof. The weft threads on one or both sides of the warp threads are formed into knitted stitches ; preferably when the weft thread 16x on one side of the warp threads is knitted the opposing weft thread 36a is unknitted. Other weft threads 16a are never knitted in. The invention is described in connection with a circular machine having radially disposed latch needles 2 and with knocking- over bits 7 of the kind described in Specification 340,825. The needles are preferably carried in a stationary bed 1 and the knitting cams 3 are mounted upon segments 5 carried upon a crown wheel 6 driven from a main shaft 12. The warp threads 17 are supplied from braked drums 18 and are guided by combs 27 .. 29 so that they pass between the needles substantially at right angles thereto. One set of weft threads 16a, 16x are supplied from bobbins 16, carried upon a ring 14 rotating with the wheel 6, and are guided by devices 46 on the outside of the warp threads. The devices 46 also serve to spread and position the warp threads. The second series of weft threads 36a pass from bobbins 36 mounted upon a second crown wheel 30 to the inside of the warp threads, and are supplied to the needles by feeding devices 44. The needles may be of three kinds having butts at different positions, and of these, one form may always knit the thread 36a, while not knitting a weft thread 16a. The other two forms alternately knit a weft thread 16a, but do not knit the thread 36a. The weft threads 16a, 16x, 36a may be passed through feelers mounted upon an arm 68, Fig. 18, controlled by a spring 69. Upon breakage of the thread the arm 68 and a pawl 24 are swung so that the pawl engages a ratchet wheel 22. Movement of the ratchet wheel 22 displaces a shaft 25 which operates a clutch 26 or other machine stopping device.
