Title: Temperature-compensated accelerometer of the floated pendulum type
Inventor: SAWYER BRUCE ALDEN
IPC: G01P15/13
Filed: 1964-07-22
Abstract: 1,069,676. Measuring acceleration electrically. LITTON INDUSTRIES Inc. July 22, 1964, No.29606/64. Heading G1N. A temperature compensated floated pendulum type accelerometer comprises a cylindrical pendulum element supported in a flotation fluid (e. g. bromotrifluoroethyline), a magnetic pick up to detect angular displacement of the pendulum, a torquer to apply null restoring torque and arrangements to reduce errors caused by variation of ambient temperature. Construction. The cylindrical pendulum element 13 (Figs. 1, 2), forming the centre portion of a shell 14, has an air tight buoyant chamber 37 and an adjustable mass assembly 39 and the centre of mass CM is displaced from the axis of symmetry A-A and the centre of buoyancy CB is on the axis A-A. The element 13 is on a shaft 31 supported by jewelled bearings 15, 16 so that the rotational axis B-B is offset from the axis A-A. A line joining the centre of bouyancy CB and the centre of mass CM passes through the rotational axis and in the operational orientation of the pendulum would be perpendicular to the line of acceleration C-C. One end of the shell carries four serially connected torquer coils 23 which co-operate with a stationary 4 pole permanent magnet field. The other end carries pick off coils 21 which co-operate with a stationary A. C. excited salient pole field 46, to produce an A. C. signal corresponding to angular displacement of the pendulum. The signal is fed to a demodulator amplifier where it is compared with an A. C. reference voltage and the amplifier D. C. output constitutes the restoring torque current applied to torquer coils 23. The amplitude of the torquer current is proportional to the magnitude and its polarity is representative of the direction of displacement, and hence of the magnitude and sign of the acceleration. Temperature Compensation. Variation of the magnetic field of the torquer and variation of density of the fluid due to temperature variation can cause error. Variation of the magnetic field would vary the torque current required to maintain the pendulum in its null position. This is offset however by the fluid density change, in that, variation in the turning moment on the pendulum due to change in buoyancy acts to balance variation in the null restoring turning moment due to change in the torquer permanent magnet field. Hence the torquer current remains substantially constant with  temperature. In addition a temperature insensitive resistor is connected in parallel with the torquer coils to make the torquer current even more independent of ambient temperature. To compensate for fluid volume expansion a bellows 42 is provided. Hydrostatic pressure gradients resulting from temperature induced variations in the flotation fluid cause a shifting of the centre of buoyancy and this cause of error is minimized by the cylindrical shape of the pendulum.

Title: Automatic clamp opening device for sewing machines
IPC: D05B3/14
Filed: 1955-10-18
Abstract: 774,660. Sewing machines. SINGER MANUFACTURING CO. Oct. 18, 1955 [Nov. 1, 1954], No. 29666/55. Class 112. A work clamp is opened by a cam through a member which may be shifted to connect operatively the cam and the clamp opening mechanism, and the opening mechanism is then held by a latch in the open position. The drawings show in the at rest position, a machine for attaching buttons. The pivoted upper jaw 15 of the work clamp is coupled by a link 35 to an arm 36 of a rock shaft 37 provided with an arm 41 coupled by a link 42 to a push rod 38. The push rod is moved to the raised position by a cam 74 on the drive shaft 17 acting through a bell crank 77 on a shaft 80, and is held raised by a latch 88 engaging a notch in the rod. The machine is driven by a V-belt 43 engaging a pulley mounted on the drive shaft 17 and provided with a loose flange 45 the position of which is controlled by a swinging frame 46 pivoted at 47. To start an operating cycle the bellcrank 63 is operated by the pull-chain 65 to raise the slide-bar 61 and move the frame so that the flat spring 50 thereon moves the pulley flange 45 to make the drive effective. The latch 68 is released from the point 71 of cam 69 and moves to engage the collar 67 and hold the bar 61 in the raised position. The movement of the frame, to the left of the position shown in Fig. 3, causes the pivoted latch 88 to be disengaged from the notch in the push rod 38 by the finger 92 and moves the shaft 80 to disengage the bell crank 77 from the cam 74. Release of the push-rod 38 causes rotation of the rock shaft 37 and closure of the work clamp, which is held in work-gripping relation by a presser bar adjustably biased by a spring 33. At the end of the cycle the latch 68 is tripped by points 70, 71 on cam 69 and a stop-block 57 on a rod 53 resiliently centred on a lug 54 on the frame 46 engages a notch 58 on the hub of the fixed pulley flange 44 to bring the machine to rest with its various parts in the positions shown.

Abstract: 409,221. Cathode-ray tubes. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Oct. 26, 1933, No. 29796. Convention date, Oct. 26, 1932. [Class 39 (i).] In a cathode-ray tube provided with a spherical fluorescent screen, one or more of the beam-deflecting systems, provided each for giving one direction of deflection, is constituted by a group of separate sub-systems arranged at different positions along the length of the tube and so operated as to have a common centre of deflection such that the beam length to the screen is the same for all directions of deflection, the centre of deflection being coincident with the centre of curvature of the screen. Deflecting plates B are disposed between pairs of deflecting plates A, C which are located in planes perpendicular to the planes containing the plates B and form a deflecting system. The sizes of the plates A, C and the voltages thereon are such that the centre of deflection due to the plates A, C is coincident with that due to the plates B and also with the centre of curvature of the screen 5. The length of each of the plates A, C may be half that of the normal plate when using normal deflecting potentials, or the plates may be of normal length and half the normal deflecting potentials applied thereto. The potentials for A, C may be adjusted by means of a potentiometer circuit, and the deflecting systems may be constituted by an odd or even number of deflecting sub-systems, or magnetic deflecting means may be used. When using a combination of magnetic and electrostatic deflecting means, a common centre of deflection may be obtained by arranging the magnetic deflecting system at a greater distance from the screen than the electrostatic means.

Filed: 1957-09-24
Abstract: 872,517. Irradiation apparatus. HIGH VOLTAGE ENGINEERING CORPORATION. Sept. 24, 1957 [Sept. 28, 1956; Oct. 8, 1956(2)], No. 29932/57. Class 98(1) [Also in Group XL(a)] Objects or packagings other than continuous lengths of materials are irradiated with high energy electrons by dividing a stream of electrons produced by imparting a scanning movement to a beam from a single source into two portions, each of which is directed on to the object to be irradiated and at least one of which is deflected and redirected on to a part of the object inaccessible to the other portion of the stream. Three types of apparatus are described : the first (see Fig. 3) comprises an electron accelerator, the lower part of which is shown at 3, supporting means such as a conveyer belt 8 for the object 6, and a magnet 9 indicated by broken lines, whereby the portion of the beam not initially incident upon the object is redirected on to the opposite side of the object. As illustrated a hollow member 11 having an electron window 12 is arranged to surround the redirected electron beam and to be adjacent to the electron window 4 of the accelerator: a pump 13 may be provided to evacuate this member, or it may be in direct communication with the accelerator without an intermediate electron window or it may be filled with a lowdensity gas such as helium; the member may however be omitted. In the second apparatus (see Figs. 4 and 5), the electron beam passes out of the accelerator through two electron window assemblies 4<SP>1</SP> and 5<SP>1</SP> terminating in windows 6<SP>1</SP> and 7<SP>1</SP> which face opposite sides of objects 6 supported on conveyer 8. Two magnets 11<SP>1</SP> and 12<SP>1</SP> having poles 13<SP>1</SP>, 14 and 15, 16 respectively direct the divided electron beam through the electron windows. In the third form of apparatus (see Figs. 8 and 9), specially adapted for irradiating an axially aligned series of bottles, ampoules, vials or collapsible containers, the electron beam is directed by magnets 9a and 10a so that all parts of the periphery of the objects receive uniform radiation.

A needle cylinder (1) is coupled to a synchronising disc (2) having circumferentially arranged holes (4) one for each needle groove, admitting light from a lamp (5) to a photo-cell 7 connected through a pulse shaper (9) to a wale register 11 determining the number of stitches per row. A further single hole through (3) admits light once per revolution to a cell (6) connected through another pulse shaper (8) to a course register 10 which determines the number of rows. The programme matrix has a number of switches 13<SP>1</SP>-13 <SP>11</SP>n for distributing the pulses into a series of ferrite cores 14<SP>1</SP> -14n, 15<SP>1</SP> -15n &c. each having a number of control windings and an output winding e, g. 20 connected to one or more needle selecting electro-magnets through a line e.g. 19. The control windings correspond in number to the number of courses on the gauge or number of degrees in register 10. In use during each rotation of the machine, pulses appear successively on lines 17-17n and at the end of each revolution the wale register 11 is reset together with the course register 10 from which a pulse emerges on the next line e. g. 16a. Switches 13 have an off position Q. The ferrite cores should have a substantially rectangular hysteresis loop. The switches 13 set the ferrite cores into a "1" state giving an output on lines 18, 19 &c. for a corresponding pulse on lines 17-17n, or a "O" state which effectively blocks the pulse from the output lines 18, 19 &c.
