Title: Improvements in or relating to transverse stabilizing devices for vehicles
IPC: B60G17/019
Filed: 1962-03-28
Abstract: 993,569. Preventing lateral canting of vehicles. J. M. J. DELSUC. March 28, 1962, No. 11912/62. Heading B7D. An apparatus for correcting the inclination of a vehicle when negotiating curves or slopes comprises hydraulic suspension means controlled by a valve 30 having an inlet connection 30 from a pump, connections 31 and 32 to a reservoir, and connections 33 and 34 for supplying pressure fluid to the suspension means on opposite sides of the vehicle under the control of a valve spool 28 actuated by a lever 26 pivoted at 27 and moved in one direction or the other by electromagnets 25 and 25<1> forming part of an inclination - sensitive device comprising a pendulum and a turn detector gyroscope having a rotary mass 1 and a precession frame 2 pivotally mounted in an electrically insulating casing 5 by bearings 4. A lever 7, which is pivotally mounted on the frame 2 to which it is connected by springs 18, 18<1> and a lever 7<3>, is provided with a counterpoise 13 and a link 9 connected to a dashpot device 11, 12 carried by the casing 5. The pendulum 20 is pivoted at 21 to the casing 5. An electric circuit including the magnets 25 and 25<1> and a battery 35 includes a connection to a brush 14 connected to the lever 7 and making contact with one or other of segments 17, 16, 17<1>. The segment 16 is connected by a wire 36 to the pendulum 20 which has a brush 22 which contacts either an insulator 23 or one of segments 24 and 24<1> which are connected with the segments 17 and 17<1> by the wires 37, 37<1> to the electromagnets 25, 25<1>. When the vehicle is travelling along a straight course, but where there is a slope, a correction is applied to the vehicle suspension by energizing one of the magnets 25, 25<1> caused by the pendulum swinging. When the vehicle negotiates a curve and tilts, movement of the precession frame 2 is caused relative to the casing 5, and, due to the inertia of the system 11, 7, 13, momentary movement of the lever 7 is caused relative to the frame 2, energizing one of the electromagnets 25, 25<1> through a segment 17 or 17<1>, the pendulum being de-energized. When the lever 7 returns to its normal position relative to the frame 2, the pendulum 20 is re-energized and further tilt correction applied through this device. The pendulum may incorporate an oscillation damping device. The brush and segment contacts may be replaced by mercury switches and a circuit comprising capacitors and an amplifier is suggested. In a modification, Fig. 4, a contact 40 is carried by a spring from the arm 7 and makes pressure contact with studs 41, 42 when the arm moves relatively to the precession frame. A similar arrangement, 43, 44, 45 is applied to the pendulum 20 which is energized through a pair of normally closed contacts 46 and a resistance 48. When the contact 40 engages either stud 41 or 42, a coil 47 is energized and the contacts 46 are separated.

Title: Improvements in the production of artificial filaments, yarns or threads
Inventor: HOLLELY WILLIAM FRANCIS
IPC: D01D5/20
Filed: 1956-04-19
Abstract: <PICT:0815157/IV (a)/1> <PICT:0815157/IV (a)/2> In the production of artificial threads by the extrusion of a spinning solution through a jet, variations in denier are imparted to the threads by exerting upon the freshly spun threads a varying drawing action by means of a godet whose section in a plane perpendicular to its axis of rotation is rectangular with a length-breadth ratio of at least 4 to 1 and which rotates about an axis passing through the godet.  As shown in Fig. 1, a thread 1 formed by extruding viscose from a jet 2 into a coagulating bath 3 is withdrawn from the bath by a circular godet 4 and passes upwards around a guide 5 to a godet 6 whose section in a plane perpendicular to the axis of rotation of the godet is rectangular, having a length-breadth ratio of 4 to 1.  The godet 6 is symmetrically and fixedly mounted on the shaft 7.  The thread 1 passes around the godet 6 and is taken again around the guide 5 and the godet 6 before passing over a guide 8 to a funnel 9 of a centrifugal box (not shown).  The length of the godet 6 is 7 inches and the guide 5 is situated about 4 to 4 1/2 inches from its axis of rotation.  The rotational speeds of the godets are such that the maximum spinning speed is not greater than 70 metres/minute and such that the maximum ratio of drawing speed to extrusion speed does not reach the critical value, generally 3 to 1, when the thread is liable to break at the jet.  As shown in Fig. 2, the arrangement of the godets is reversed, the first godet 10 being rectangular while the second godet 11 is circular. Alternatively, both godets may be rectangular.  Instead of the axes of rotation of the godets passing through the centre of gravity of their cross-section, the axes may pass through some other point in their cross-section.  Specification 321,762, [Class 2 (ii)], U.S.A. Specification 2,120,990, and French Specification 759,928 are referred to.

Abstract: 960,312. Decorative pattern drawing instruments. S. SMITH & SONS (ENGLAND) Ltd. March 8, 1963 [March 28, 1962], No. 11974/62. Heading B6P. A drawing instrument for drawing decorative patterns comprises a supporting member 1 adapted to be held in a fixed position on a plane surface on which a pattern is to be drawn. A first member 8 is mounted on the supporting member 1 so as to be manually rotatable about a first axis 3 which is fixed in relation to the supporting member and perpendicular to the plane surface. A second member comprising plates 12 and 16, is mounted on the first member 8 for rotation about a second axis 9 displaced from but parallel to the first axis 3 and fixed in relation to the first member 8. A third member 19 is mounted on the second member for rotation about its own axis forming a third axis. First driving means comprising gears 6 and 10 causes the second member to rotate about the second axis 9 as the first member 8 is rotated by the handle 5. Second driving means comprising gears 11, 14, 15 and 30 and a shaft 13 causes the third member 19 to rotate about its own axis as the second member is rotated. The third member 19 is adapted to carry a drawing implement in the form of a stylus 23 which engages the surface away from the axis 13 as the first, second and third members rotate about their respective axes. A sheet of carbon paper is placed between the instrument and the surface, the movement of the stylus being recorded thereby on the surface. The displacement of the stylus from the axis 19 is adjustable and the third axis is adjustable with respect to the second axis 9 by adjusting relatively the angular positions of plates 12 and 16 constituting the second member. In a modified use, the stylus may be mounted by axle 41 directly on second member 12, 16 so that it rotates with but not relative to it. In a further form, the stylus may be mounted on the lower end of shaft 13.

Title: Improvements in high speed telepicture system
IPC: H04N5/257
Filed: 1937-04-29
Abstract: 494,689. Copying-telegraphy; photoelectric cells. FINCH, W. G. H. April 29, 1937, No. 12291. [Classes 39 (i) and 40 (iii)] A modulated low frequency is applied to a pair of plates 76, 77, Fig. 6, which deflect a cathode ray 86 transversely to a to-and-fro scanning oscillation caused by another pair of plates 89, 90, and optical apparatus 100, 107 produce on a sensitive photographic surface 101 an illumination, which varies in area or intensity according to the width of the luminous trace on the fluorescent screen 88. The lowfrequency is generated at the transmitter, Fig. 1, by an oscillator 43, which is coupled to an oscillator 27 producing the to-and-fro scanning movement of the cathode ray 11. The low-frequency is modulated at 40 by current from a photo-electric cell 36, 38 which is illuminated by the scanning spot on the fluorescent screen through a picture 33. At the end of each scanning line the light from the scanning spot strikes a separate photo-electric cathode 37 in the same envelope as the main one, Fig. 4 (not shown). The resulting impulse controls mechanism 61 for advancing the film 33 one step transversely to the scanning movement of the cathode ray and is also mixed with the picture signals. At the receiver the synchronizing signal is separated by an amplitude filter 93 and controls the mechanism 103 stepping the film 101 and the oscillator 91 which produces the linear sweep of the cathode ray. The lens 100 concentrates the luminous trace to a single line and a filter 107 reduces the effect of the horizontally central part compared with that of the edges, Figs. 7 and 8 (not shown).

Title: Improvements in or relating to frequency dividers
IPC: H03B19/12
Filed: 1938-04-25
Abstract: 514,063. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 25, 1938, No. 12340. Convention date, April 23, 1937. [Class 40 (v)] A frequency divider comprises a pair of valves with means for applying to the input electrodes both the control frequency and independent alternating control potentials and also potentials dependent upon the current flow in the output of the other tube. Fig. 1 shows an arrangement in which the control oscillations applied at the terminals 10 are arranged to interrupt the potentials applied from the oscillator 12 and amplifier 13 to the input grids of the pair of valves 14, 15. The bias of the grids is derived by rectifying the output of the other valve of the pair and appears across load resistances 24, 28. A potential dependent on the change in the direct current component in the anode circuit of the other valve is also applied to the grids through condensers 25, 29. In a modification the amplifier 13 and the valve pair 14, 15 are hexode valves with two separate control grids so that the voltages applied to these valves are applied to the separate grids instead of to a common grid. The divider is applicable to high speed counters and to the prevention of selective fading in radio receivers, in which the sum of the upper and lower sidebands is used to control the reinforcement of the suppressed or faded carrier. Fig. 4 shows a superheterodyne receiver in which a frequency divider 38 is fed from the intermediate frequency amplifier 32 through a frequency doubler 36 and amplifier 37 and its output used to supply carrier frequency to the second detector 33.
