Title: Improvements in reclining chairs
IPC: A47C1/027
Filed: 1933-10-04
Abstract: 414,919. Adjustable chairs. BANK, A., 100, Duncan Avenue, Jersey City, New Jersey, U.S.A. Oct. 4, 1933, No. 27339. [Class 52 (ii).] In a reclining chair, the back-rest member is pivoted to the main supporting frame and is returned to the upright position by the action of springs at each side. The back member 21 comprises side wall portions 24 and a bottom wall portion 25 and is pivoted to the main frame upon a pin 31. Attached at each side of the back member is a metal member 40 comprising a part 41 contacting with the back member, a part 43 extending at right angles thereto and a part 44 bent again parallel to the part 41 and having a spring 48 attached thereto at 44<a> and to the main frame at 47. Immediately adjacent to and coaxial with the pivot pin 31 a disc 50 is integrally mounted attached to the wall 24 by bolts 53. Each disc is formed with a slot through which passes the arm 43 of the member 40, and with a peripheral groove which receives a friction belt 58. This friction belt is attached at 66 to the main frame and at 60<a> to a spring 62 which is adjustably secured to the frame 15 by a wing nut 64. By this means the return motion of the back member actuated by the spring is retarded to prevent sudden movement. The angle of pivotal movement is limited by the member 40 striking the upper plate portions 27 and the lower plate portions 28 forming parts of the main supporting frame of the chair. In a modification not shown, the two springs 48 are replaced by a single spring which acts on both arms 40 by means of flexible connections passing round small pulley wheels which are secured on the framework of the chair.

IPC: C09F5/06
Abstract: 275,574. Harvel Corporation, (Assignees of Harvey, M. T.). Aug. 6, 1926, [Convention date]. Fats and fatty oils.-Drying oils are produced from the oil of the shells of cashew nuts or from the gum or sap of the cashew tree or from other sources of anacardic acid and cardol by treating with a metal, e.g. copper, nickel, " monel metal," lead, magnesium, calcium, or manganese or with copper or other metal oxide, hydroxide, or carbonate as stated in Specification 272,510, or with oleates, stearates, or other metal organic compounds, and adding another vegetable oil or a resin. When linseed oil is used it may be mixed with the cashew oil before treatment. Oils &c. specified for addition are linseed, tung, and china wood oils, and cumarone resin. The products are used for impregnating fabrics, cords, and paper, for coating metal wire, bars, or sheets, and for producing electrical insulating materials. They may be applied direct or thinned with a solvent, e.g. benzol, naphtha, kerosene, and gasolene. In an example previously dried cashew shell oil heated at about 200‹ C. for 4 hours in a copper vessel is mixed with an equal weight of a solution in 1 lb. of kerosene of 1 Ib. of jelly obtained by boiling linseed oil. The heating may take place under pressure, e.g. 50-60-100 lb., to hasten the reaction. The Specification as open to inspection under Sect. 91 (3) (a) is not limited to the addition of another vegetable oil or a resin, or to heating in presence of metal or metal oxide or compound provided the reaction takes place under pressure. In examples (1) raw cashew shell oil in a copper kettle is dried by heating to 100‹ C., and then maintained to 200‹ C. for ¢-8 hours; (2) cashew shell oil is heated in a copper kettle for 1 hour under a pressure of 50-100 lb.

Title: Magneto-optic elements for the storage of information
Inventor: BRAUSER KLAUS
IPC: G02F1/09
Filed: 1970-06-09
Abstract: 1282533 Magnetic storage devices MESSERSCHMITT - BOLKOW - BLOHM GmbH 9 June 1970 [18 June 1969 22 July 1969 2 Oct 1969] 27793/70 Heading H3B A magnetic storage layer read out by using the magneto-optical Faraday or Kerr effects on a polarized light beam is formed on or within a tube or rod of homogenous transparent dielectric material, such as glass, along which the polarized beam is propagated, a drive coil for establishing a storage state in the layer being wound about the tube or rod. As shown in Fig. 3, a ferromagnetic layer 11 is provided on an optical fibre 10, and a drive coil 13 is wound over an insulation layer 12, read out being effected by multiple reflections at the ferromagnetic layer of a polarized light beam 20, which causes the Kerr effect polarization rotation detected by an analyser 30 to be accentuated. In Fig. 5 the light beam 20 is passed with multiple reflections within a glass tube 110 coated with ferromagnetic material 111 on its inner surface. A modification, Fig. 7, uses a wire 15 of ferromagnetic material surrounded by a light conductor tube 10 of higher refractive index than an external transparent dielectric coating 110. The magnetic state of the ferromagnetic material is determined by a current pulse in the encircling coil 13, 113, the current being produced either by light 30, Fig. 8, of a different frequency to the reading light beam 20, striking a photo-sensitive layer 414 and causing a photo-electric current to pass to an anode 46, or by applying an electron beam to one end of the coil, Fig. 9 (not shown). A group of rods or tubes 110 may be assembled as shown in Fig. 10 to form a store, a common conductive layer 613 and analyser 630 being associated with the light emissive ends of the rods, and a segmented photo layer 414 towards which reading light 20 or a different frequency writing light 30 is selectively directed being located at the light incident ends of the rods. An erasing coil may surround the assembly of rods or tubes, Figs. 12 and 13 (not shown). A modified storage assembly, Fig. 14, includes a non-segmented photo layer 814 spaced from the rods or tubes, parallel writing being effected by applying a light beam pattern 830 to the layer 814 which causes a corresponding pattern of electrons to pass to the coils of the rods or tubes. Parallel reading is effected as shown in Fig. 15 in which a light source 912 illuminates a selective filter and a polarizer 911, 912, the resulting light beams passing to the tubes or rods. In a modification, Fig. 16, a glass rod 310 is coated at one end with a partially transparent ferromagnetic layer 313 and a transparent anti-reflecting coating 314, a coil 315 establishing a particular magnetic state in the layer 313. Monochromatic incident light 340 polarized at 320 is subjected to both Kerr reflection and Faraday rotation, the respective reflected and transmitted beams 350, 351 having their polarization rotations detected by analysers 321, 322.

Abstract: 445,194. Sluice valves. ATELIERS NEYRET-BEYLIER & PICCARD-PICTET, Avenue de Beauvert, Grenoble, IsÚre, France. Sept. 28, 1934, No. 27844. Convention date, Sept. 30, 1933. [Class 68 (ii)] [See also Group I] A flume with a gradually -rest ric - ted section is fitted with a vertical partition or partitions adapted to be moved across the flume so as to divide in any desired ratio the flow, which thus passes to branch channels. Figs. 1 and 2 show a flume with constricted sides b, c and a hump-shaped bottom forming a weir D. These constrictions cause the current to flow at a critical velocity equal to the rate of propagation of surface waves. A partition V, movable about a vertical or approximately vertical axis a, divides the current as desired between the two channels shown in Fig. 2. Fig. 4 shows in plan a distributing-partition or gate in two parts V<1>, V<2>; the part V<1> is pivoted on a nearly vertical axis a<1>, and the part V<2> moves parallel to the sides b, c of the flume, being constrained by linkwork p. The movements are effected by a screw M. The flume has a hump-shaped bottom, as shown in Fig. 2, but the sides are parallel. In other modifications, the part V<1> is replaced by a staunching-block, and the part V<2> is moved, parallel to itself, by screw gearing ; a part V is fitted in one or both entrances to the branch channels, and is moved by rack-andpinion gearing ; the bottom of the flume may be raised, for example, by means of screw lifting-gear.
