Abstract: 467,806. Testing hardness of materials. WOLPERT, O., (trading as HESSENMULLER & WOLPERT). Feb. 5, 1937, Nos. 3424 and 4834. Convention dates, Feb. 5, 1936 and March 3, 1936. [Class. 106 (ii)] A hardness - testing machine is provided with a movable loading slide having movably mounted thereon the indentor device and also part of an optical magnifying and projecting system either of which may be brought into operative position on the specimen. A sleeve 2 adapted to slide in the head 8 of a frame 1 is closed at the lower end by a nose piece 3 in which is rotatably mounted a carrier 4. The latter has an arm 5 carrying an indentor and spa c e d angularly therefrom, another arm 6 carrying part of an optical system co-operating with a source of light 7. Pivoting at 9 is a forked lever 10 carrying the weights 11 supplying the load which is transmitted to the sleeve 2 by bearings 12. A cam 13 turned by hand serves for applying the load or taking it off. This cam is coupled to the carrier 4 by linkage and rack and tooth gear 17, 18 so that when the load is raised the indentor is swung away from its line of action and the optical element 6 into place. A lens and prism at the top of the sleeve 2 bring an image of the indentation on to a screen 15 where it may be measured by a scale 26. Mounted alongside the indentor is a stop adapted to be engaged by the surface of the specimen when the table 24 is raised by its screw and provided with a contact to cause a signal light to show when engagement takes place ; thus ensuring that the surface of the specimen is always brought into the same focal relation with respect to the optical magnifying system.

Patent GB-403240-A (GB)
Title: Improvements relating to the crystallization of substances that crystallize exothermically
IPC: C25D1/08
Filed: 1933-02-06
Abstract: Substances which crystallize exothermically' e.g. ammonium nitrate are crystallized from their hot solutions by applying and maintaining a sufficiently reduced pressure to cause evaporation of the solvent, resulting in saturation and consequently partial crystallisation of the solution.  The heat thus produced exothermically causes further evaporation of the solvent followed by further crystallisation and the cycle is repeated until complete crystallisation and desiccation are obtained.  Two or more such salts or a salt mixed with an insoluble suspension may be crystallised in this manner. Specification 301,496, [Class 32, Distilling &c.], is referred to.

Title: Improvements in and relating to pulp molding dies
IPC: D21J7/00
Filed: 1940-02-27
Abstract: 535,523. Moulding pulp. TRIGGS, W. W. (Keyes Fibre Co.). Feb. 27, 1940, No. 3633. [Class 87 (ii)] Pulp moulding dies of the type provided with wire mesh covered draining surfaces shaped to the contour of the article required are constructed of a number of parallel sections 6, Fig. 6, each section being covered with a wire mesh section 10, Fig. 5, of similar contour and having marginal edges 11 which overlap the edges of the sections so that when the sections are bolted together the edges of the wire mesh are clamped therebetween. The sections are held in a clamping ring 9 which is screwed down to the sides and ends 2, 3, 4, 5 of the die which are themselves screwed to a bottom plate 1 adapted for attachment to a die carrier on a pulp moulding machine. In constructing the die all the sections are separately finished except for the finishing of the contour of the working surface. The die is then assembled without the wire covering and shims are inserted in lieu of the overlapping ends of the wire mesh. The die is then given its final contour, e.g. on a die sinking machine. The contour may be that of the combination flat and filler described in Specification 423,248, [Group XVII].
Patent GB-376249-A (GB)
Title: Improvements in or relating to inclinometers
IPC: G07D9/06
Filed: 1931-02-05
Abstract: 376,249. Inclinometers. KREIDLER, A., 71, Herdweg, Stuttgart, Germany. Feb. 5, 1931, No. 3744. Convention date, Feb. 12, 1930. [Class 97 (ii).] In an inclinometer for use on moving vehicles, the planes of movement of a main movement member and an auxiliary movement member, adapted to eliminate the effects of acceleration, intersect one another. In the form shown in Fig. 1, a main pendulum comprises the weight 1, arm 2, and spindle 3, which is rotatably mounted in a stand 4 and carries a bevel wheel 5 driving the indicating drum 8. The correction element 11 is rotatably mounted on the arm 2 and is provided with a cam 15 bearing on the upper end of a locking lever 13 carried on the arm 2. The element 11 is normally maintained in line with the spindle 3 by a spring but on the occurrence of acceleration swings round the arm 2, the cam 15 causing the locking lever 13 to engage the toothed disc 10 on the stand 4 and lock the main pendulum. In the modification shown in Fig. 3, the arm 21 supporting the weight 20 of the main pendulum is slightly inclined to the vertical so that the correcting element 24 rotatably mounted thereon is normally aligned with the spindle 22 by gravity. A bevel wheel 26 fixed on the hub of the element 24 engages a bevel wheel 28 freely mounted on the spindle 22. A toothed wheel 29 fixed to the wheel 28 drives the indicating drum 37 through gearing 30, 36. Variations in inclination cause the elements 20, 24 to swing together about the axis 22 and thus turn the wheel 28 and drum 37. On the occurrence of acceleration, the main pendulum swings about the axis 22 and the correcting element and wheel 26 about the arm 2 so that the wheel 26 merelv rolls round the wheel 28 without turning it. Escapement mechanism 33, 34, 35 is connected to the spindle 31 of the wheel 30 to ensure that the members 20, 24 swing synchronously. In a further modification locking means controlled by the correcting element are combined with the construction shown in Fig. 3. Two correcting elements arranged in toothed engagement so as to be independent of centrifugal force may be used.

Title: Improvements in or relating to methods of sealing metal bodies to ceramic bodies
Inventor: COHEN EDWARD
IPC: C04B37/02
Filed: 1957-02-06
Abstract: 832,251. Brazing. GENERAL ELECTRIC CO. Ltd. Feb. 6, 1958 [Feb. 6, 1957], No. 4177/57. Class 83 (4). [Also in Group XXXVI] Ceramic and titanium or zirconium parts of a thermionic valve are joined by brazing the metal to the ceramic in a vacuum or inert atmosphere with a brazing metal of copper, silver, or gold, or their alloys. A metal other than titanium or zirconium, for example an alloy of iron, cobalt and nickel may be joined to a ceramic by first brazing a foil of titanium or zirconium to the ceramic using copper, silver, or gold as the brazing metal, and then brazing the foil to the first metal. The two brazings may be carried out in a single operation, and a titanium or zirconium foil coated on one or both sides with the brazing metal may be used. Forsterite ceramics may be brazed to titanium by the method, and ceramics of alumina and mullite may be brazed to zirconium. The inert atmosphere may consist of argon, and the brazing metal may be placed as a foil between the two parts to be joined together, or it may be applied to the boundary of the joint in the form of a wire which when melted is drawn between the surfaces by capillarity. Alternatively, the brazing metal may be applied to one or both parts to be joined together. A seal between titanium and forsterite may be made by brazing with a eutectic alloy of copper and silver at 900‹ C., and between zirconium and alumina or mullite with silver at 975‹ C. Pure gold and gold-copper alloys containing up to 30% of gold may also be used for brazing. A tube of alumina forming a part of a thermionic valve is sealed to a disc of iron-cobalt-nickel alloy by placing between the two parts a ring of titanium plated on both sides with a coppersilver eutectic alloy and heating in vacuum to 900‹ C. In another example, titanium pins are sealed through holes in a ceramic disc forming the base of a thermionic valve by placing round each pin three turns of copper-silver eutectic wire and heating the assembly to melt the wire and cause it to flow between the pins and disc. Specification 832,252 is referred to.
Patent GB-479979-A (GB)
Title: Piezo-electric crystal apparatus
IPC: H03H9/00
Filed: 1937-02-12
Abstract: 479,979. Piezo - electric crystals. STANDARD TELEPHONES & CABLES, Ltd. Feb. 21, 1937, No. 4301. Convention date, Feb. 21, 1936. [Classes 40 (iii) and 40 (v)] A piezo-electric crystal is vibrated in its nth harmonic mode by energization by n, pairs of electrodes 20, 29, ... 24, 25, Fig. 3, interconnected so that they are alternately positive and negative. The crystal is preferably an X-cut, Fig. 1 (not shown), the width or length dimensions making an angle #=-18À5 to +5‹ with the optic axis, Fig. 2, 4 (not shown). The significance of the + or - is related to whether right- or left-handed quartz is employed and is a convention set out in Bell System Technical Journal Vol. XIII, p. 437. The -18À5‹ orientation results in a maximum shear oscillation; the -7À5‹ orientation gives maximum piezo-electric effect while the -10‹ orientation gives a small temperature coefficient of frequency. The ratios of the length and width dimensions, m<1>, o<1> are chosen to give a minimum mechanical coupling between the selected harmonic and any other oscillation. For example, for #=-18À5‹ and the third harmonic, o<1>:m<1>=0 to 0À23, 0À255 to 0À275, 0À46 to 0À6. These limits are obtained by calculating the ratios o<1> : m<1> at which width, depth and shear oscillations are equal to the desired harmonic, the values so obtained constituting limits to be avoided. Ratios o<1> : m<1> are given for #=-18À5‹ and the 5th, 7th and 9th harmonics, and indications are given for determining the range of ratios for other orientations. The crystal is preferably vibrated at an odd harmonic, so that its centre forms a node at which it can be pivoted ; the clamping pivots may be the leads to the electrodes. The two sets of electrodes (i..e. positively and negatively energized) are preferably formed by plating the whole crystal and removing the plating so as to leave each set integral, Figs. 6-10 (not shown). The crystal may take a tuning fork shape, Fig. 15 (not shown). The electrodes may be divided into two equal systems so that the crystal acts as two crystals of equal frequency Fig. 11 (not shown). Such a crystal 110, Fig. 12, may provide the two series arms 114, 116 of a lattice filter, the shunt arms 118, 120 being constituted by a second such crystal 112. A narrow band filter comprises two crystals 130, 132, Fig. 13, coupled to the balanced hybrid coil transformer 131.
