Abstract: 1,044,767. Knot-tying machines. E. FREUDLING. June 5, 1963 [June 5,1962], No.22439/63. Heading D1C. A method of tying a reef knot comprises forming U shaped loops in one end of the thread in parallel planes, turning them through 180 degrees to form crossed loops, moving the other end through the loops and then pulling the ends apart. A strap is held by holding means 17 and passes around a package 1, between holding members 3, 5, around a holding member 15, between holding members 2 4 and the other end 14 is held on a clamping lever 79 (not shown). The holding members 2,4 and 3,5  are advanced towards each other respectively producing U shaped loops 23, 24 these processes being facilitated by the movement of the holding member 15 in the direction of arrow 25 Fig. 3 (not shown) or the clamping lever 79 in the opposite direction to allow the introduction of more thread. The holding members 4, 5 are rotated in the direction of the arrows 30, 31 respectively to form the crossed loops 32, 33 Fig. 4 (not shown). A threading means 34 is then advanced through the loops in the direction of arrow 35 (Fig. 5) to take the end of the thread 18 from the holding means 17 and this threading means is then retracted in the direction of the arrow 36 to pull the end 18 through the loops 32, 33. The holding means 2, 3 4 and 5 are then retracted and the knot is pulled tight around the holding member 15 and eventually slides off thismember and lies against the side of the package. A blade 93 (not shown) severs the end 14 of the thread or strap to the desired length.

Title: Improvements connected with the control of the ailerons and elevators of aircraft
IPC: B64C13/00
Filed: 1919-09-12
Abstract: 156,859. Bolas, H. Sept. 12, 1919. Steering and balancing. - The elevators and ailerons can be operated independently or simultaneously by a single hand lever, and the extent to which the elevators and ailerons are moved by a given movement of the hand-lever can be varied by adjusting a sleeve along the lever. The handlever B is pivoted to a longitudinal tubular shaft A. Movement of the lever in a fore and aft direction actuates the elevators through the rod G. Movement in a transverse direction rocks the shaft A carrying arms E to which the aileron-operating cables F are connected. Adjustment of the sleeve H along the hand-lever B varies the distance of the elevator-operating rod G from the pivoted end of the lever and, at the same time, through a link P and arm 0 and a Hooke's joint, rocks a shaft J within the shaft A and thereby, through arms K and links L, moves pins M, to which the aileronoperating cables are connected, along slots in the arms E. According to the Provisional Specification, the control lever may be mounted upon a transverse rocking-shaft on which it can hinge sideways. Bell-crank levers connected to the ailerons work on horizontal pins at each end of the cross-shaft, and are actuated by side movements of the control lever through connecting rods engaging slots in a bracket on the control lever. The elevators are operated from a second cross-shaft which is connected to a sliding sleeve on the control lever by an arm and a universally jointed rod. Movement of the sliding sleeve on the control lever thus adjusts the leverage at which that lever acts upon the elevator-shaft and, at the same time, it adjusts in their slots the connecting-rods to the bell-crank levers which operate the ailerons.

Title: Method and apparatus for cementing together rubber threads to form a unitary ribbon
IPC: B29B15/12
Filed: 1958-07-14
Abstract: 843,804. Fabric composed of adhesivelyunited threads. GOODRICH CO., B. F. July 14, 1958 [July 15, 1957], No. 22517/58. Glass 140. A method of producing a ribbon constituting a single unit from a number of continuous rubber threads comprises the steps of continuously forming the threads into a band, urging the threads into edge-to-edge contact in the plane of the band to form a ribbon, vibrating the threads in a direction transverse to the plane of the band to remove cross-overs and localized tensions and applying cement to the band and drying the cement so that the threads become cemented together, the threads being pulled along under light tension throughout the whole process. As shown (Figs. 2 and 3) the threads are drawn off drum 10 over roll 16 which rotates at twice the peripheral speed of the drum and roll 19 rotating at the drum speed, and are spaced by combs 23 and 33, then pass under beaters 36 and 37, over grooved roller 43 and through separator assembly 44 which divides them into groups of threads which are to be cemented to form ribbons. The threads then pass under concave crowding plates 46 and 47, over knurled roll 48, rotating in a direction opposite to the thread motion to vibrate the threads, then over cement applicator roll 49 whose lower portion dips into liquid cement in pan 56, over concave glass crowding roll 52, under scraper 53, and through notches in ribbon guide plate 54. The ribbons then pass, for drying, between upper and lower resistance heaters 73 and through a radiant heater drying section wherein they pass over rolls 74, 76, 77, 78 and 79 and are subjected to radiant heat from infra-red lamps 82. The dried ribbons are then delivered into cartons 133 by peel-off rolls 81, 108, 109 and 111. The threads may be formed initially by slitting thin sheets of coagulated rubber latex and may be vulcanized before use in the process. A suitable cement comprises vinyl chloride plasticized by an acrylonitrile rubber and made tacky by a phenolic resin. A suitable solvent is methyl ethyl ketone.

[Also in Division G3j Fuel is supplied from a reservoir 1 to a plurality of injectors 11 connected one following another to a conduit 10 by an engine driven fuel pump 2, a fuelflow regulator 8 is provided upstream of the injectors and downstream of the injectors the conduit 10 is connected via a calibrated orifice 12 with the reservoir. Each injector 11 comprises a plunger 17 actuated by an engine cam-shaft and fuel flows to an injection chamber 34 through an inlet passage 27 and a calibrated orifice 15. The regulator 8 comprises a centrifugal governor 43, 44, 45 driven by the engine or a piston (65), Fig.14 (not shown), subjected to the output pressure of the pump 2, which pressure increases as the square of the engine speed, moving a slide valve 36 against the bias of a main spring 50 and a slow running spring 55. The valve 36 controls the inlet 38 to the conduit 10 and the inlet 39 to a by-pass passage 37 leading to the reservoir 1 via a calibrated orifice 13. The main spring loading is controlled by a manually operated member 52 movable between adjustable stops 53 and 54. The regulator housing 48 is filled with fuel and the slide valve disc 47 acts as a damper. To provide excess fuel for engine starting a further spring (58), Fig. 11 (not shown), is disposed between the base of the slowrunning spring housing 49 and the adjacent end of the valve 36, the slow running spring 55 bearing against an apertured washer (47) engageable with a shoulder in the regulator housing.

Title: Improvements in or relating to devices comprising a closed circuit of magnetic material having high retentivity
IPC: G11C11/06
Filed: 1954-08-05
Abstract: 776,076. Static induction and apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 5, 1954 [Aug. 8, 1953], No. 22791/54. Class 38 (2). [Also in Groups XIX and XXXIX] In a device comprising input and output windings 2, 3, Fig. 3, which are coupled by a magnetic circuit 1 having high retentivity and a hysteresis loop shaped like a parallelogram but not rectangular, the voltages induced in the output winding by excursions of flux between the retention level of magnetization 11, Fig. 2, and the saturation level 13 in response to a magnetizing current pulse i, in the input winding are neutralized by opposing voltages of equal magnitude derived from the output winding 6 of a similarly constructed correcting device which has a low retentivity magnetic circuit 4. Only those transient induced voltages which have a magnitude determined by 13-12 and result from a reversal of magnetic polarity by a pulse are then effective at the output terminals CD, and the arrangement is thus functionally similar to a basic device in which the hysteresis loop of the magnetic circuit is substantially rectangular. The pulses must act simultaneously in winding 2 and in the input winding 5 of the correcting device, these windings preferably being connected in series as shown although they may be separately energized from synchronous sources. A single correcting device may be common to a number of basic devices, Fig. 5 (not shown), or to the cores 1<SP>1</SP>-9<SP>1</SP> of a matrix memory device, Fig. 6. In the latter case the correcting device neutralizes spurious outputs which arise from flux changes in unselected cores, the input winding 11 being connected in series with either all the column or row windings or with both as shown, while the output winding 12 is in series with the read-out winding 13. A correcting device comprising input and output windings 16, 17, Fig. 10, may also be used to increase the effectiveness of a non-contactmaking relay comprising a saturable transformer controlled over a winding 14.
