Title: Method of and means for generating a triggering signal
Inventor: USUI K
IPC: G01P15/08
Filed: 1971-04-19
Abstract: 1337481 Crash bags NISSAN MOTOR CO Ltd 19 April 1971 [4 July 1970] 26554/71 Heading B7B [Also in Division G1] A vehicle safety device such as an inflatable bag or burstable safety netting is triggered only when the magnitude and rate of deceleration resulting from a mechanical impact are a predetermined value. This value is such that the safety device is triggered for both vehicle-tobarrier and sidewise vehicle-to-vehicle collision only when the impact would cause crucial damage to the vehicle and occupants and the invention is based on the fact that the decelerating magnitude increases substantially linearly at an initial stage of the impact, Fig. 1 (not shown). A voltage signal α proportional to the magnitude of deceleration at impact is fed from detector 10 to differentiator 11 which derives a decelerating rate A<SP>1</SP>, B<SP>1</SP> representing the rates for a vehicle-to-barrier collision and sidewise - vehicle - to - vehicle collision respectively, Fig. 2, the range between A<SP>1</SP>, B<SP>1</SP> being divided into sub-ranges II, III and IV. The output from differentiator 11 is compared in comparators 12p, 12q, 12r and 12s with reference voltages P<SP>1</SP>, Q<SP>1</SP>, R<SP>1</SP>, S<SP>1</SP> corresponding to the decelerating rates P, Q, R, S of Fig. 2, where P<SP>1</SP>>Q<SP>1</SP>>R<SP>1</SP>>S<SP>1</SP> and the comparators 12p, 12q and 12r produce an output when the input is lower than the respective reference voltage and comparator 12s an output when the input is higher than the reference voltage S<SP>1</SP>. The deceleration magnitude signal a is also compared in comparators 13t, 13u, 13v with reference voltages T<SP>1</SP>, U<SP>1</SP>, V<SP>1</SP> corresponding to the decelerating magnitudes T, U, V, Fig. 2, where T<SP>1</SP><U<SP>1</SP><V<SP>1</SP> and each comparator 13t, 13u, 13v produces an output when its input is higher than the respective reference voltage. AND gates 14a, 14b, 14c and 15 are connected as shown to the comparators and to the input of a normally open switch 16 controlling the safety device triggering. The arrangement is such that for impacts in the ranges I and V the AND gate 15 is not enabled and the safety device not triggered whereas in the ranges II, III and IV the AND gate 15 is enabled and the safety device triggered.

Title: Method and apparatus for determining stress
IPC: G01N3/40
Filed: 1971-04-19
Abstract: 1335763 Determining stress in materials R G STURM 19 April 1971 [15 April 1970] 26589/71 Headings G1W and G1S A diamond indenter 110, Figs.2 and 3, is actuated to make a first crater in a test piece under stress and a second crater in a test piece not under stress or in an unstressed part of another of the same metal test piece. The craters are then photographed, measured and compared and a number of characteristics determined and calculated which enables the stresses in magnitude and orientation in the test piece to be ascertained without destroying the piece. The indenter mechanism 14 may pivot about a fulcrum pin 31 from the inoperative position of Fig.2 to a position where a notch 56 is engaged by a pin 30 so that the diamond 110 is over the test piece. In the swung away inoperative position a graticule microscope 11 and a camera 12 of conventional design or some optical or electronic scanner may be used on the crater. The intenter, Fig. 3 comprises plates 41, 42 separated by spacers 48, 49 and rotatably mounted on pin 31 through an eccentric bushing 44, the opposite sides of the plates being notched to receive the pin 30. Flexible plates 51, 52 which may be deflected vertically but not horizontally are spaced apart by cylinders 54, 55 about the pins and bearing washers 58, 59 are provided. A connector beam 61 and screws 62 hold the pieces together. An assembly 100 including a plunger 101 holding the diamond 110 is received by the plates 51, 52 and a hollow casing 105 positively locates the plunger for vertical movement as 51 and 52 flex. When a wheel 230 is rotated by a spanner to screw a stud 228 into the plunger it causes the underside of the wheel to engage the plate 42 and flex the plates 51, 52 to lift 101 and 110. When the wheel is oppositely rotated to retract stud 228 it attempts to raise itself, but since an anvil 224 is urged downwardly by a spring 222 the retraction of stud 228 causes plunger 101 to move downwardly until point 111 contacts the test piece whereupon spring 222 forces the point to form a crater. When the spring force is overcome by the reaction of the test piece the cup 206 is raised and the movement and force exerted indicated on a dial gauge. Wheel 230 is rotated to zero the gauge land each time the apparatus is used to ensure that the same force is applied each time. Once the crater has been made the tip and indenter are pivoted aside to allow the microscope and camera to operate. The diamond tip may be aligned by rotating the eccentric 44, and the angle of the tip may be 135 degrees or 160 degrees.

Abstract: 1340411 Flow-meters SOC INDUSTRIELLE D'ELECTRONIQUE ET D'INFORMATIQUE 19 April 1971 [3 Aug 1970] 26704/71 Heading G1N [Also in Division H1] The speed or mass flow of a gas is determined by causing a corona discharge in the gas between a source electrode and a collector electrode so as to produce a flow of ions perpendicular to the gas flow, and measuring the difference in potential between two sections of the collector electrode, the two sections being separated by an insulating gap arranged so that ions impinge on both sections whatever the flow-rate. As shown in Fig. 2, the source is an elongate wire 1 and the collector is formed of two triangular plates 9,10 separated by a gap 11. Alternatively the plates may have interengaging triangular teeth, Figs. 3 and 4 (not shown). The triangles may be truncated. To improve linearity between flow rate and potential difference, a plate of substantially the same area as that of the collector may be arranged parallel to the collector and adjacent to the source so as to have approximately the same potential as the source, Fig. 5 (not shown), or the insulating gap may have a theoretically determined curved shape, Fig. 6 (not shown). As shown in Fig. 7, the source is provided by a disc 27 and the collector by a pair of cylinders 23, 24 having toothed ends which inter-engage to form the gap. The teeth may have a theoretically determined curve shape, Fig. 8 (not shown). The collector signals may be integrated with respect to time to determine the total flow.

ANON, POUR LES APPLICATIONS DE L'ELECTRICITE ET DES GAZ RARES-ETABLISSEMENTS CLAUDE-PAZ & SILVA]. Sept. 20, 1955 [Sept. 22, 1954], No. 26855/55. Class 39(1). A lamp cathode is activated by heating the whole lamp to at least 900‹C while evacuating or flush ing with an inert gas. The lamp is of a high silica content material such as quartz, and has a filling of mercury plus argon, krypton, or xenon, at an operational pressure of >0À5 kg/cm. The electrodes comprise a refractory metal member with electron-emissive material, the melting point of the material, and of its non-gaseous products, being >2500‹C. The electrode is a tungsten rod 7 carrying at one end a tungsten helix, the turns of which hold the emissive material 6. This may be calcium carbonate, ball-milled and diluted with butyl acetate in specified proportions. This is sufficiently adhesive for application by dipping or brushing without a binder. Lime or thorium oxide may be used as the basis of the emissive material, which may also have finely powdered tungsten or silica mixed with it. To activate the cathode, the whole lamp is baked in an oven at about 1100‹C. for 15 minutes. The rod and helix may also be of molybdenum or tantalum. The helix holding the emissive material may be double, as at 23, and an empty helix 22 may be provided in front of the other. The rod 7 is welded to a thin molybdenum strip 10, further thinned at the edges, welded in turn to a thicker strip 9 forming the lead-in connection. The strip 10 eventually forms the vacuum-tight seal with the quartz envelope.

Abstract: 303,578. Kaisser, K. Oct. 12, 1927. Driving-arrangements.- In a starting-device for a motor equipped with a clutch, and especially for a motor with a short-circuited rotor, the starting unit is controlled directly or indirectly by centrifugal elements in the clutch. In the form shown the clutch, which is of the beltpulley type operating through an expanding ring 3, has a sliding sleeve 2 normally pulled to the right by tension springs 1 to the position shown in the lower half'of the Figure. This sleeve is linked by rods 4 to a ring 5 which bears on sliding studs 7 attached to a switch-operating ring 8 and urged by compression springs 6 so as to keep the ring 8 retracted within the end plate of the clutch. Centrifugal members (not shown) move the sleeve 2 and rings 5, 8 to the position shown in the upper part of the Figure when the motor reaches a limiting speed, with the result that the upper lever 11, which bears on the ring 8 under the action of a spring 13, moves into the position shown in dotted lines and closes a switch 14. This closure completes a circuit which switches the starter from the starting to the running position. In an alternative arrangement a sleeve, such as 2, bears on levers directly linked to a ring such as 8 and the stud 7 carries a wire for operating the starter mechanically. The casing 15 of the switch is adjustably guided by means of journals and shafts 17, 18 in a member which is secured to the motor foundation.

In apparatus for the projection of animated cartoons, two collimating lenses 1 pass parallel light from alternately illuminated film strip images 9 through a single large lens 2 which focuses the image on a screen in alternate superposition. The illumination at the two strips 9 is alternately gradually reduced and increased in complementary fashion with a frequency as low as 10 times a second. The strips 9 may be images for diascopic or episcopic projection, lamp 5 being used in the latter case and also for illuminating scenery elements or slides 4. The images on strips 9 are moved suddenly when their respective illuminations are least, the image change being synchronous with the light variation. In Fig. 1 the diascopic alternate lighting is provided by a polarizing filter 15 rotating behind fixed crossed polarizers 17 to front of lamps 14. Similar fixed and rotary polarizers 7 and 8 interrupt the light from lamps 5. Lenses 16 and 18 pass parallel light through filter 17. In the embodiment of Fig. 3 (not shown) the alternating lighting is provided by a rotating circular wedge (19) of neutral grey glass combined with a similar wedge (20) of clear glass. Condensers 23 and 24 are used. Semi-silvered mirror prisms 12 are used with projectors 13 to superimpose fixed or moving images on strips 9 for projection by lenses 1, 2. These images may replace those on the strips for episcopic projection. Specification No. 1,001,545 is referred to.
