Filed: 1973-03-02
Abstract: 1374931 Inertia-locking safety belt retractor R C FISHER 2 March 1973 [3 Nov 1972] 10191/73 Heading A3V An inertia-responsive safety belt retractor comprises a take-up spool 16 for a belt 12 journalled in a frame 46 and having ratchet teeth 111 on its peripheral flanges, a locking pawl 98 mounted on the frame and having locking projections 108, 110 engageable with the ratchet teeth 111, a spherical inertia responsive member 210 on a conical seat adapted on inertial displacement relative to its seat to pivot the pawl 98 into its locking position to prevent belt withdrawal, and further projections 118, 120 on the pawl to balance the latter dynamically against inertia forces in the horizontal "A" plane thereby ensuring that the pawl responds only to displacement of the member 210 and is insensitive to spurious inertia forces. In the embodiment shown the member 210 bears on a tab 112 on the pawl through a plunger 212, but the inertia member may be set higher and bear directly on the pawl. The pawl is additionally statically balanced so as to have a slight counter-clockwise bias against the plunger 212. In the locking position of the pawl, a line through each of its support points on the frame 46 and the corresponding point of contact with the ratchet teeth 111 is tangential to the periphery of the spool. The slope of the conical seat determines the inertia force required to effect locking of the retractor. The following abridgment is included in this series since the Specification was through an error, not allotted to this group. Reference to it will be found in the name index to this volume.

Title: Apparatus for use in estimating the total area and/or size-distribution and/or totalnumber of discrete particles situated in or projected on a field of view
Inventor: BELL DAVID ARTHUR
IPC: G06M11/00
Filed: 1951-05-03
Abstract: 707,651. Photo-electric particle counting apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 25, 1952 [May 3, 1951], No. 10355/51. Class 40 (3) An estimate is made of the total number of particles in a collection and of the number in each of a number of size groups by traversing a mesh of alternate opaque and clear spaces relatively to the collection and measuring the mean square current of a photo-electric cell receiving light through the mesh. The invention is based on that fact that if the fluctuating output current of the photo-cell is analysed into a number of frequencies by the use of filters in the photo-cell circuit then the mean square current I<SP>2</SP> r  in a frequency band of width df and with a centre frequency f where f is small compared with <SP>1</SP> t  (t being the time for the boundary of light area on the grid to traverse the particle) is given by the equation I<SP>2</SP> f  = C d f # N k  A k <SP>2</SP> where N is the number of particles of area A k . Thus the value of # Nk Ak<SP>2</SP> may be determined by measuring the mean square current at a low value of f or by observing this mean square current when the pattern is moved at a high speed so that :all frequencies are small compared with <SP>1</SP> t . If a particle is of comparable size to the mesh its effect on the means square current will be negligible, thus by varying the size of the mesh a measure may be made of the number of particles in particular size groups. Alternatively if a large mesh is used a curve may be plotted of mean square intensities at different frequencies this curve then being compared with a set of curves appropriate to various size distribution. As shown, Fig. 3, the specimen is mounted on the stage 4 of microscope 5. A parallel beam of light illuminates a grid 7 and a polygonal rotating mirror 10 traverses a reduced image of the mesh, produced by a lens system 8 across the specimen. The light passing through the specimen is concentrated by the microscope on to a photo-cell 11 which is connected through one or more filter networks to root-mean square measuring devices. Instead of reducing a large mesh optically a small mesh, such as a powder sieve may be used. In an alternative arrangement the image of the grid may be projected through the eyepiece, the photo-cell being placed below the stage. In the arrangement of Fig. 4 (not shown) the grid is fixed in the place of the image of the specimen produced by the objective. Relative movement between the field of view and the grid is achieved by means of a transparent rectangular block rotating between the grid and the specimen.

Title: Improvements in spark-plugs
IPC: H01T13/38
Filed: 1920-04-16
Abstract: 141,740. Hill, R. R. April 5, 1916, [Convention date]. Sparking-plugs. - The casing 3, constricted from material having the same coefficient of expansion as that used for the engine cylinder, is taperbored to receive lavers of mica insulation 4 which are tightened in position by the insertion of the conical central rod 6. The insulation before insertion is slightly greater in diameter than the casing, and the angle of taper of the electrode slightly exceeds that of the casing; the electrode, therefore, acts as a wedge, causing the layers of insulation to slide relatively to each other during insertion. The mica wrappings extend beyond the casing and are enclosed by a second insulator 7 which may consist of mica washers. Provision is made for cleaning the terminals and priming the cylinder by forming the electrode hollow with a cupped outer end 16, normally closed by a screwed plug 17. At its inner end, the conical portion of the electrode, is longitudinally split and fitted with a sparking joint 14 which, however, is not inserted far enough to prevent the priming or cleaning fluid from issuing from the hollow electrode. A rounded edge 1<a> at the outer end of the casing and on the electrode at the inner and outer extremities of the split 13, prevent the tendency for the insulation to break down at those points.
