Title: Improvements in or relating to gas discharge tubes
Inventor: MAYER CECIL HEDWORTH
IPC: H01J17/49
Filed: 1962-03-28
Abstract: 967,685. Cold cathode tubes. HIVAC Ltd. March 18, 1963 [March 28, 1962], No. 11926/62. Heading H1D.  A method of introducing mercury into a low pressure gas discharge tube comprises introducing within the tube envelope prior to pumping and sealing a quantity of a staple oxide of mercury together with a suitable agent such as red or amorphous phosphates for reducing the oxide to free the mercury on heating subsequent to sealing the tube. One preferred composition is 4.3 grm. Hg 0 to 0.3 grm. phosphorus giving 20% excess phosphorus which is dispersed and assists in clearing any other free oxygen in the tube. The mixture is placed within a thin-walled metal capsule 22 welded to a C-shaped member 21 of solid wire forming a closed turn which is placed within an R.F. field, thus heating the composition and disrupting the capsule wall. A mica disc 17 has openings to permit the mercury vapour to pass into the body of a character display arrangement 14-16.

Title: Method and apparatus for inspecting dielectric articles
IPC: G01B7/06
Filed: 1972-03-15
Abstract: 1380349 Electrically measuring thickness OWENS-ILLINOIS Inc 15 March 1972 [16 March 1971] 11942/72 Heading G1N The thickness of wall portions of articles made of dielectric material is determined by establishing and detecting an r.f field at an article inspection station, and comparing the detection output when an article is absent from the station with that when an article is present at the station. As shown in Fig. 1, glass bottles B are conveyed to an inspection station 20 where they are each rotated and scanned by at least one detector. As shown in Fig. 3, the field is established by an  antenna 46, and the field is detected by a probe 49 whose output is applied to a linear r.f. amplifier 51 which provides a D.C. signal related in amplitude to the amplitude of the detected field. This signal is applied to one input of a comparator 60. An integrator 80 is connected to the output of comparator 60 via a switch SW which is operated by an indexer 70 which operates the mechanism to position and remove the bottles from the inspection station. When no bottle is at the station, the switch SW is closed and the arrangement of the comparator 60 and integrator 80 is such that the output e2 of the integrator 80, which is applied to the other input of the comparator, is driven to zero. When a bottle is positioned at the inspecting station, the switch SW is opened and the output e 2  then remains constant. Then the output e 0  of the comparator is directly proportional to the thickness of the wall portions of the bottle being scanned. The fixed output e 2  is utilized to provide a nominal wall thickness reference signal via potentiometer 90 for comparison with the thickness signal e 0  in a comparator 150. Since the absence of a bottle at the station and detection of a bottle having a wall portion which is too thin both produce an output at the comparator 150, a second comparator 120 is utilized as shown to operate a reject control 130. A counter 110 counts the number of acceptable bottles.

Title: Pressure-responsive solid state electric switch
IPC: H01C10/10
Filed: 1973-03-13
Abstract: 1414045 Pressure responsive solid state switches; contacts KOMBINAT KERAMISCHE WERKE HERMSDORF VEB 13 March 1973 11990/73 Headings H1N and H1K A pressure responsive solid state electric switch comprises an elastomer with 20-60% by volume of dispersed particles of metal chalcogenides, which can exist in a state of high conductivity as well as in a state of low conductivity (i.e. bi-stable conductivity). Application of a compressive force causes a change in the volume dispersion, brings about an abrupt resistance change, and causes the switch to become conductive. A quantitative example is given. Suitable metal chalcogenides are vanadium oxide or iron sulphide and the particles can be coated with other materials to improve conductivity, examples being given and also of suitable elastomers. Fixed connecting electrodes such as wire nets or metal powder layers can be incorporated into the elastomer and piezoelectric or magnetic substances (ferrite) can be provided on or below the elastomer surface for bringing about elastomer deformation by means of electric or magnetic fields.

Filed: 1936-04-30
Abstract: 474,427. Clocks. WEBB, J. W. April 30, 1936, No. 12249. [Class 139] Striking - mechanism.-In a synchronousmotor clock wherein the synchronous motor actuates the striking hammer d, d<1> by means of a constantly rotated cam c, the striking is controlled by a ratchet wheel f having abutment pins g<1> spaced circumferentially according to the hours and coacting with an arm g rigid with the hammer arm d, striking being initiated by a pawl m<1> operated from the minute wheel l and being stopped by the arm g abutting against the next pin g<l>. The rotor z of the motor continuously drives a shaft x carrying a pin wheel a and a double cam c having two extensions c<3>. The shaft b of the hammer arm d carries also the arm g, an arm b2 coacting with the cam c, an arm b<1> coacting with the pins a<1> on the pin wheel a, and an arm e carrying a pawl e<1> which feeds the wheel f during striking. When striking takes place, a pin a<1> raises the arm b<1>, and with it the hammer arm, and as the pin a<1> wipes free of the arm b<1> the end of arm b<2> falls on to the cam extension c<3> at the point c<4>. Thereafter the end of arm b2 falls suddenly off point c<1> to effect a strike. As the shaft b thus oscillates, the pawl e<1> feeds the wheel f until the spring pin g<2> on arm g abuts against the face of the next pin g<1>, when the pawl e<1> is unable to take back over another tooth. To initiate a new striking operation the wheel f must be fed two teeth by the pawl m<1>. The latter is carried on an arm m rigid with a shaft j. Another arm h on shaft is rocked by a pin h<1> on the minute wheel l in order to cause pawl m<1> to feed the ratchet wheel f two teeth.

Title: A system for automatically correcting for the doppler effect in a sound detection system
IPC: G01S1/72
Filed: 1959-04-13
Abstract: 918,022. Frequency discriminators; measuring velocity by acoustic waves. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. April 13, 1959 [April 28, 1958], No. 12496/59. Classes 40 (5) and 40 (7). A sound-detection system for measuring velocities includes a frequency discriminator comprising a condenser C charged from a source (not shown) through a rectifier r 1  and discharged through a rectifier r 2  so that the voltage V across R will be proportional to the source frequency, the resistor R being connected to a variable voltage E and the cathode of r 2  being connected to the cathode of a cathode follower T the grid of which is connected to the anode of r 1 . It is proved mathematically in the Specification that the middle frequency r (corresponding to V = O) of the discriminator is proportional to E and that if a frequency being measured deviates from # by an amount ## then V will be proportional to ## independently of the amplitude of the input. The cathode follower output voltage V K  = U 1 +V and the voltage V K  provides the control voltage for one of the oscillators in the sound detection system. The discriminator D is included in a Doppler meter (Fig. 4) on a moving craft to compensate for the Doppler effect beat frequency #F P  which is proportional to the radial velocity of said craft. The signal transmitted is of frequency F = F 2  - F 1  (derived from oscillators F 1 , F 2 ) and the received echo signal is frequency changed at A 1 , A 2 , A 3  until it is equal to F 3  - F 1  - F 4 + #F P + #F P  = F<SP>1</SP> where #F B  is the Doppler effect frequency of the moving target which is to be determined. In order that F<SP>1</SP> should be made equal to 900 c/s.+ #F b , F 3  - F 1  - F 4  = (f) must be made equal to 900 c/s. - #F P , and this is achieved by supplying a signal of frequency f to the discriminator, the output V K  of which will then be a signal of frequency Te = f - #, this output signal V K  then adjusting oscillator F 3  until Te is zero, when f = # and the above condition will be met. Since # can be adjusted by varying E if E is made proportional to #F P  then the compensation for #F P  is introduced. #F P  can be determined at any moment by a computer on the vessel.

Title: Fraction collection apparatus
Inventor: GORHAM GEORGE
IPC: G01N1/18
Filed: 1953-05-06
Abstract: 725,736. Filling test-tubes &c. TECHNICON CHROMATOGRAPHY CORPORATION. May 6, 1953, No. 12645/53. Class 125 (2). Relates to the type of apparatus described in Specifications 655,896, 679,992, [Group XXX], and 689,079 in which test-tubes T to be filled with determined quantities of material from a supply 56. are mounted in four concentric rows in an intermittently rotated carrier 12 and in which the liquid supply pipe 44 is first aligned with the inner row and then, after the first row is filled, is automatically pivoted about the axis of its shaft 162 to fill the second row and so on until, when the fourth row is filled, it is further pivoted to discharge into a drain 68. The invention provides an improved means of pivoting the supply pipe. When the first (innermost) row of tubes has been filled, a stud 20 depending from the carrier 12 abuts a cam surface 194 on an arm 82 rotatably mounted on the shaft 162. The arm is thus pivoted clockwise, Figs. 2 and 3, and a pawl 120, pivoted to the arm and engaged in a notch T<SP>1</SP> in a ratchet plate 84 fixed to the shaft 162, rotates the ratchet plate one step to rotate the shaft 162 and to position the supply pipe 44 over the second row of tubes T. The ratchet plate is justified in its new position by a roller 260 moving from-recess T5 to recess T<SP>6</SP>. The roller is carried on a bell-crank 236 and is urged into engagement with the plate 84 by a spring 246, the other end of which is anchored to a plate 248 which is adjustable to vary the spring tension. When stud 20 rides off the cam part 194, a spring 204 returns the arm 82 to its original position in which a stop 200 on the arm engages a fixed stop 230, the pawl 120 falling into the notch T<SP>2</SP>. The pawl is spring-urged into engagement with the ratchet plate 84. This action is repeated for the third and fourth rows of tubes, the pawl 120 and roller 260 lying respectively in notches T<SP>3</SP>, T<SP>4</SP> and recesses T<SP>7</SP>, T<SP>8</SP>. Meanwhile, an abutment 222 on the plate 84 has been advanced from the position shown in Fig. 2 to that shown in broken lines in Fig. 3. When all the tubes are filled second stud 22 on the carrier 12 engages the abutment 222 to move the ratchet plate sufficiently far that the pawl 120 leaves notch T4 and rides on flat part 262 of the plate 84 and the roller 260 moves on to a cam surface 210 on the plate. The stud 22 then clears the abutment 222 but the roller 260 under the action of spring 246 runs down the surface 210 to rotate plate 84 until it enters a deep recess 212. In this position, supply pipe 44 is above the drain 68. The parts are restored to the first filling position manually, when a knob 88 has been actuated to cause a link 116 to disengage the pawl 120 from the ratchet plate 84. Rotation of the plate 84 in either direction is limited by a stud 224 thereon engaging one or other of the fixed abutments 226, 228. Rotation of carrier 12 in the drain position of the pipe 44 is stopped by the opening of a micro-switch 220 by an abutment 216 on plate 84.
