Abstract: 375,010. Loud-speakers. WILLSON, H. C., Walton, Beckminster Road, Wolverhampton. April 16, 1931, No. 11283. [Class 40 (iv).] A method of assembling the component parts of an electro-dynamic loud-speaker or the like involves the use of a jig, whereby the parts including the moving coil and its centring member are accurately positioned with respect to the magnetic air gap. During the assembling of the parts, the jig is temporarily mounted on the frame of the instrument, and after its removal the field magnet is fixed on the frame in a position coaxial with that previously occupied by the jig. The loud-speaker shown comprises a pressed steel casing a having a back-plate a<1> to which a permanent magnet b is secured, the magnet being enclosed by a dust cover c. The moving coil d<1> is carried by a tubular support d, attached to a conical diaphragm e, which may be made of moulded buckram &c., the diaphragm being peripherally secured to the frame a by rivets h. A flexible spider f, serving to centre the coil support and the attached inner end of the diaphragm, is carried by pillars g on a flat ring k, which is adjustably screwed to the plate a<1>. In assembling the instrument, the ring k is first loosely secured to the plate a<1> by screws passing through clearance holes. The tubular support d carrying the coil d<1> is next placed upon the projecting part m<1> of the jig m, Fig. 3, and the jig is fitted on to the back of the casing a, a shoulder m2 spigotting into an aperture in the back-plate a<1>. The jig is held loosely by screws passing into tapped holes in the ring k. A plug n is then inserted through the spider into a central hole in the jig, the head n<1> fitting accurately into the coil support d. The plug serves to shift the spider slightly, if necessary, to centralize it correctly. After the screws holding the rink k and the jig have been tightened up, cement is applied to the adjacent parts of the spider and coil holder d, and the projecting end e<2> of the diaphragm e is lightly pressed through the hole in the spider into the tube d. The rim of the diaphragm is then secured to the flanged edge a<2> of the casing by means of a clamping ring and rivets, and the jig is removed. Wires leading from the coil d<1> are soldered to connections on the spider, from which wires lead to insulated terminals on arms of the casing a. Finally, the magnet b is fitted with its shoulder b<1> entering the aperture in the plate a<1>, and is secured by bolts p, and the cover c is placed in position. Instead of positioning the jig and the magnet on the back-plate a<1> by means of shoulders entering an aperture, dowels or the like may be used.

Abstract: 580,535. Range-finders. BARR & STROUD, Ltd., and FRENCH, SIR J. W. July 13, 1943, No. 11399. [Class 97 (i)] An adjuster for a parallax measuring instrument such as a range-finder or height-finder is provided with a component compensated for errors due to a transverse temperature gradient and with a component uncompensated whereby the parallax error of the uncompensated component can be determined so that an appropriate parallax error correction can be applied to the range-finder if uncompensated or to an adjuster, when fitted, if uncompensated. In the form shown in Fig. 1, the compensated component comprises a glass medium A extending between the objectives 26, 27 carrying marks 28, 29. The objectives are carried by glass plates 60, 61 which support the objectives of the uncompensated component which also includes an adjustably mounted prism 63. The beams from the marks 28, 57 are deflected by a prism 54 and the coincidence error of the uncompensated component determined. When the components form part of an adjuster or range-finder system, the prism 54 is semi-silvered, whereby the light from the compensated component is passed to the end pentagonals of the apparatus. The means for moving the prism 63 are mechanically connected to a rotatable head 89, Fig. 7, having a scale 90 and geared at 91, 92 to a disc 87 having a range scale observable through a window 88, the disc being also rotatable from the range head 84 through the gears 85, 86. In one form, Fig. 11, the space 76. in the adjuster tube is evacuated and may be filled with a gas such as helium with a lower refractive index than air and therefore less subject to parallax errors. Specifications 28728/06, [Class 97], 580,531 and 580,534 are referred to.

Abstract: 945,885. Reworking worn valve guides by rotary rubbing tools; reamers. BESLYWELLES CORPORATION. March 31, 1960 [July 17, 1959; Nov. 23, 1959], No. 11482/60- Headings B3A, B3C and B3V. In a tool 10 for working a cylindrical hole in a workpiece a tapered screw. threaded portion 22, Fig. 1, is provided for starting a screwthread on the surface, a cylindrical screw-threaded portion 20 develops the screw-thread thus started and a sizing portion brings the surface of the workpiece to the required diameter. The sizing portion may comprise a burnisher 18, Fig. 1, or reamers 52, Fig. 6, 102, Fig. 9 (not shown), or 114, Fig. 10. Using a tool 12 shown in Fig. 1 having a burnisher 18 with an effective diameter equal to the original diameter of the bore, the bore, for instance in stainless steel, may be work hardened without altering the size. Similarly constructed die-like tools may also be used to work the external surface of shafts or rods. In operation the tool 10 is inserted into the bore to form the thread and is then withdrawn the threads on the reversely tapered portion 24 of the tool forcing the crests of the thread formation outwards during withdrawal to a point where the burnisher- 18 acts to finally resize the bore. Where the final bore diameter is less than the original dimension a helical groove 42 is left in the surface. In working the less ductile metals, such as cast iron, reamers replace the burnisher to reduce the degree of working the tool (e.g. Figs. 6 and 10, being passed through the bore in one direction only. The leading reamers e.g. 50 or 110 initially sizing the bore while the following reamer e.g. 52 or 114 cuts the bore to the final required diameter. The tool of Fig. 10 is provided with guiding portions 108, 116 while in a further embodiment the reamer flutes are continued through the guide portion 116 to facilitate removal of swarf. In another embodiment, Fig. 9 (not shown), a single reamer 102 finally sizes the bore during withdrawal of the tool. Various forms of thread for the tools are disclosed and it is stated the root and crest of the thread and also the surface of the burnisher are relieved at circumferentially spaced points. Single or multiple start threads may be used. The cavity formed by the tapered portion of the tool and the surface of the work may act as lubricant reservoir.

Abstract: 940,946. Drying foams of food &c. A. I. MORGAN, L. F. GINNETTE, and R. P. GRAHAM. March 30, 1961 [April 5, 1960], No. 11665/61. Heading A2D. [Also in Divisions B1 and F4] A foamed product formed from a solution or dispersion of a solid material in water is applied to a perforated surface and a gas is forced in through the perforations at a sufficient velocity to displace that portion of the foam overlaying the perforations, whereafter the foam is dried. As shown in Fig. 2, a foamed product is supplied at 4 on to a moving perforated support 1 which travels over a nozzle 3 through which a current of gas is fed at a sufficient velocity to displace the foam overlaying the perforations. The foam is then carried through a drying apparatus 16, operated with a hot gas supplied at 18 and withdrawn at 19, and a cooling apparatus 20, and the treated foam is detached from the support 1 by blades 25, 26. A modified apparatus is described (Fig. 3, not shown) in which the dryer 16 is divided into two sections through which the drying gas passes first in the same direction as the foamed product and then in the opposite direction. The dryer may include supplementary heating means. In the apparatus shown in Fig. 4, the foam is supplied at 43 to a perforated tray which passes over a gas blower 45 and thence to a duct 48 up which the trays are lifted, drying gas being supplied both at 49 and at 51 and the gas leaving the duct 48 through the aperture 50. The trays are withdrawn at 47 and the treated foam passes over a cooler 52 and is collected at 55. More than one aperture 50 may be provided in the duct 48. The material to be treated may be converted into a foam by incorporating air or other gas into the material, optionally after preliminary concentration or addition of a surface-active material and (or) a hydrophilic colloid, many surface-active agents and hydrophilic colloids being specified. Many materials which may be treated are also specified, including fruit, vegetable, meat, fish and milk products, food for animals, tanning agents, vitamin preparations and enzyme products. The gas used for the preliminary treatment of the foam on the perforated surface is preferably air, but reference is made also to the use of nitrogen, carbon dioxide, nitrous oxide, helium, propane, n-butane, isobutane, dichlorodifluoromethane, trichloromonofluoromethane or monochlorotrifluoromethane. The preferred drying gas is air, but nitrogen, carbon dioxide, helium or combustion gases may also be used.
