Abstract: 360,894. Sound-reproducing machines. HUGUENARD, E. A., 19, Rue Dupont de 1'Eure, Paris. Aug. 8, 1930, No. 23746. [Class 40 (ii).] Relates to sound-reproducing machines in which a grooved record film is employed, such a record being of the hill-and-dale type. According to the invention, a rigid diaphragm of conical or equivalent form is vibrated by the action of a stylus engaging the record, the diaphragm being flexibly connected to the periphery of an aperture in one of the walls of a box. As shown in Fig. 1, the diaphragm 10 may be connected at its apex to one end of a lever 6 which carries a sapphire or the like bearing on the film record 1, the other end of the lever being pivoted at 7 to a displaceable support 8. The diaphragm has a flexible connection 11 to the edge of a circular opening in a casing 12 which encloses the whole apparatus, and which forms a resonance box. In a modification, Fig. 2 (not shown), the lever 6, instead of being pivoted at 7, is free at this end, which carries an inertia weight, the other end being pivotally connected to the cone diaphragm so that it can rotate around the axis of the cone. In this case, an endless film record is used, the sound-groove being slightly inclined to the centre line of the film. Fig. 3 shows another construction, in which the box 12, to which the diaphragm 10 is connected, is external to the latter and to the film driving mechanism. Adjustable openings 16 are formed in the box, to vary the damping effect. In this arrangement, the film 1 may also be used for kinematographic projection.

Title: Improvements in and relating to carburetting water gas
Inventor: WILLIAMS NORMAN HENRY
IPC: C10J1/213
Filed: 1948-09-16
Abstract: 654,283. Carburetted water gas. HUMPHREYS & GLASGOW, Ltd. Sept. 16, 1948, No. 24354. [Classes 55(i) and 55(ii)] In carburetting water gas by heavy oil. in an " empty" carburetter the walls of which are heated by combustion of blow gases which pass therethrough with a spinning motion, carbon burning air is admitted, additional to that required for burning the blow gases, peripherally at one or more points so situated that the air does not mix thoroughly with the gases, but only with that part of the stream which contacts the carburetter wall. The carburetter shown comprises an upper inlet chamber a separated by an annular projection c through which passes a throat d, from the carburetting chamber proper b. Gases from the generator enter chamber a tangentially and pass through this cham-- ber, the throat d and chamber b with a spinning motion. During the blow phase, blow gases burn with secondary air admitted in the generator carburetter connection in a. At the throat d, air is admitted through tangential ports 10, 12, 14 and 16, whilst below the throat in the outwardly sloping portion of projection c, four radial air ports 22, 24, 26 and 28 are provided. If required another tangential set of ports 34, 36, 38 and 40 may also be provided in chamber b. Due to its admission at the periphery of the whirling gas stream, the air keeps in the outer layer of moving gases and is thus available to burn off any carbon deposit on the chamber walls. The excess air present in part of the blow gas stream need not come into contact with the control portion thereof, thus allowing unburnt gas to pass through the carburetter to be burnt in the superheater or used for steam raising when required. Specification 654,285 is referred to.

Title: Improvements in or relating to piezo-electric crystals
IPC: H03H9/19
Filed: 1936-09-09
Abstract: 464,894. Piezo - electric crystals. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 9, 1936, No. 24610. Convention date, Sept. 30, 1935. [Class 40 (v)] A quartz piezoelectric crystal is cut so that its principal surface is inclined at an oblique angle of 37 to 40 to the optic axis and parallel to an electric axis, and its length and width are proportioned so as to render the crystal capable of oscillating at one frequency only in its electric axis mode of vibration. If the desired frequency is f and x is the dimension in the electric axis, fx=k where k is a constant determined from the curves A of Figs. 7, 8, 9, according as the low, normal, or upper mode of vibration is to be utilized. The ranges of the constant k so taken are further limited by consideration of curves B, relating k to the frequency variation with temperature. Thus, a valve of k is selected corresponding to a zero frequency variation with temperature, e.g. for curve A, Fig. 8, k will be 242.1. The abscissa corresponding to this is 0À463 and is the ratio of the width to the length. The thickness d is determined by the equation d = f<1>k, where f<1> is the frequency of oscillation in the thickness dimension and k = 67. The curves of Figs. 7, 8, 9, correspond to an angle of 38À6 between the optic axis and the face of the crystal. The Specification indicates how the curves are modified for other angles between 37 and 40.
