Title: Improvements in and relating to menstrual tampons
IPC: A61F13/20
Filed: 1935-09-06
Abstract: 456,854. Catamenial appliances. RABELL, (nee JOHNSTON), M. E., 10, Bonmar Road, Pelham Manor, New York, U.S.A. Sept. 6, 1935, No. 24869. [Class 81 (ii)] A menstrual tampon comprises an inner absorbent member of cotton gauze or the like and an outer, less absorbent member serving to position the tampon in the vagina and formed wholly or in part of spirally wound cotton batting or like material. Passages for conducting liquid to the interior are thereby provided. The members 10, 11, of hemispherical or other shape, are formed by winding a strip of batting on a revolving mandrel and are secured on either side of a disc 12, comprising a number of layers of absorbent cotton gauze, as by sewing around the edges. A moistureproofed withdrawal cord 15 may be attached to the disc 12. Only the member which is uppermost in use need be spirally wound.

Title: Electrical surge absorber devices
IPC: H02H7/00
Filed: 1975-06-10
Abstract: 1493455 Surge absorbers MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 10 June 1975 [10 June 1974 19 July 1974] 24890/75 Heading H2H To prevent thermal runaway in a surge absorber comprising a ceramic housing 10 including a sealed cavity 13 containing a non- linear resistor 19 of material substantially zinc oxide with appropriate additives (thereby dispensing with the usual series spark gap), a terminal plate 22, a compression spring 23 and a conductor 28 connecting plate 22 with a cap 24 of the housing, the connection from the resistor 19 to the other cap 35 of the housing is formed by a terminal plate 20 having a central opening 41 receiving a conductor rod 30, which is soldered to the plate 20 to retain it against the force of a compression spring 34 and which is connected by a conductor 39 to a terminal 38 in the cap 35. Normally the leakage current through resistor 19 is small and the circuit is maintained by members 20, 30, the former including an 0-ring 21 to complete, with cap 24, the sealing of cavity 13. When the current increases to a value such that the temperature of resistor 19 approaches that leading to damage thereto, the heat conducted to members 20, 30 causes the solder to melt and conductor 30 to be moved out of contact with plate 20 through an opening 37 in the terminal 38. Hence in addition to breaking the current through the resistor 19, the cavity 13 is vented to atmosphere through the opening 41 in plate 20 and an opening 40 in the cap 35. Movement of the end 32 of conductor 30 through the opening 37 indicates operation of the protective arrangement and the need for consequent maintenance action, particularly if arcing should occur between members 20, 30 after separation. In a modification, Fig. 3 (not shown), this arcing is used to puncture a thin central part (41) of the plate 20, to which part the conductor 30 is soldered, and so vent the cavity. The modification shown in Fig. 4 uses gravity to break the connection between a conductor 49 soldered to a cap 45 at its central opening 48, the cap 45 serving both as a seal for housing 10 and a terminal plate for the resistor 19. Fig. 4 may be modified in like manner to the Fig. 3 embodiment, with arcing between members 45, 49 causing puncture of a thin central part (53) of the cap 45, Fig. 5 (not shown). The composition of resistor 19 and other members, such as 20, 23, 24 and 28, is specified.

Abstract: 156,342. Swales, W. H., and Humphries, H. T. Oct. 13, 1919. Disc and like plate hinges; double hinges. -In a mosquito-curtain frame comprising two sets of hinged stays, each set comprises three members with flat ends 1<a>, 9, 19 which are coplanar and are pivoted together on a pin 3. The pin passes through the end 9 of the centre stay and through cheeks 10, 11 secured to the ends 19, 1<a> of the outer stays respectively. Relative rotation of the cheeks is limited by stops, preferably provided by forming the ends of the parts 1<a>, 19 obliquely, so as to abut against the sides of the centre part 9 when the frame is spread out, as shown in Fig. 5. Twopart links 5, Fig. 4, connecting certain stays in the two sets, are double-jointed by means of 'bars 14, and are provided with slidable sleeves (not shown) which are adapted to cover the joints so as to hold the links rigid.

A shaft coupling comprises a series of metal balls 19 located in axial part-cylindrical grooves 20, 21 formed in hub and sleeve members 11, 12, and retained in position by a pair of split spring rings 24, 25 let into the hub or sleeve member and spaced apart a distance greater than the ball diameter to provide a working clearance when the shafts are in alignment. The rings are formed with finger portions which are bent inwardly partially to encircle the balls and thus hold them in position upon separation of members 11, 12. The radius of grooves 20, 21 is three to five per cent greater than the ball radius to provide clearances permitting relative angular movement of members 11, 12 under torque, as shown in Fig. 3, whereby the points of contact with the balls lie on non-radial lines AB and the balls operate under compression rather than shear. Fig. 1 shows an arrangement for connecting two shafts through a pair of hubs 10, 11 and a sleeve 12, such arrangement accommodating angular misalignment and end-float of the shafts.

Abstract: 1505070 Bleaching lignocellnlosic material CANADIAN INDUSTRIES Ltd 10 June 1975 [11 June 1974] 25845/74 Heading D1P In a process for bleaching lignocellulosic material, the material is contacted in an aqueous medium with a mixture of nitric oxide and nitrogen dioxide wherein the nitric oxide component is in molar excess in respect of nitrogen dioxide, then washed with water and then contacted with alkaline material in the presence of water. Nitric oxide is used at a pressure ranging from atmospheric to 200p.s.i., 0.5% to 10.0% by weight based on the cellulosic material of nitrogen dioxide is used. The different procedures employed to produce nitrogen oxides including one in which nitric oxide is used are listed in the specification. The nitrogen oxides treatment is carried at a temperature ranging from room temperature to 120C, 1.0% to 6.0% by weight of alkali or alkaline Earth base such as sodium hydroxide, calcium hydroxide, may constitute the alkaline treatment which is carried out for 10 to 180mins. at 30-90C in the presence of water. Alternatively an alkaline oxygen medium in the presence of water is used. The medium may contain oxygen or oxygen containing gas, such as air, at a partial pressure of oxygen of 30 to 200p.s.i. and used at a temperature ranging from 80C - 200C for 10-60mins. The medium also contains an alkali or alkaline earth base. The above steps may be followed by qonventional bleaching steps such as chlorine treatment wherein 0.5%- 1.5% by weight of chlorine dioxide is used to treat the material for 60-300mins. at 60- 80C followed by caustic extraction using 0.25-2.0% of base for 60-120mins. at 40 - 70C and followed by a second chlorine dioxide treatment. In each case the material is washed with water. An alkaline oxygen treatment in aqueous medium may precede the nitrogen oxides treatment. Various other treating combinations using oxygen, peroxide, hypochlorite, chlorine and chlorine dioxide, may be employed. These are listed in the specification including the examples. The material may be wood pulp, bagasse or straw.
