Title: Improvements in bone-conduction hearing-aids
IPC: H04R11/00
Filed: 1934-08-13
Abstract: 444,175. Instruments for deaf persons. SONOTONE CORPORATION, 19, West 44th Street, New York, U.S.A. Aug. 13, 1934, No. 23374. Convention date, Aug. 11, 1933. [Class 40 (iv)] In a bone-audition hearing-instrument comprising two magnetic structures separated by a gap and set in relative vibration by audio frequency currents in suitable windings, one magnetic structure supported against a hearing inducing bone is a resilient member connected at its ends to the other magnetic structure, which is relatively of substantial mass, thereby supporting it in a floating vibrating condition. The resilient member is connected at its centre to a casing one portion of which is shaped to fit the bone structure of the user. The instrument comprises a member 7 adapted to be held against the bone structure of the user and carrying the electromagnetic unit which is enclosed by a cover 8, the instrument being carried by a head strap 16 connected to a U-member 13 pivoted to the sides of the cover. A resilient magnetic strip 26 is secured by screws 60 at its centre wider portion 51 to a metal plate 56 moulded into the member 7, and at its narrower ends supports a magnet structure comprising a plate 27 and polepieces 28 secured together by members 34 screwed to the strip 26. After the magnet structures have been assembled the pole faces are ground level with the corresponding faces of the members 34, the gaps being subsequently adjusted by screws 37. The gaps are preferably about ¢ inch long but gaps up to 3 inches in length may be used. The ends of the windings 41 are connected to lugs 46 riveted to sockets 47 in the member 7 which receive pins 6 terminating the microphone and amplifier circuit. In a modification, a single winding has a core screwed into the centre of plate 27 for gap adjustment. The surface of the member 7 is shaped to fit the bone structure of an individual user, or members 7 may be shaped for different types of bone structure and the most suitable selected for the individual concerned. Alternately, as shown in Fig. 15, the surface is of a shape generally conforming to the bone structure and has a number of projecting portions 162 which intimately engage the bone structure.

The legs have cut-outs 6a to assist this collapse. The bolt 3 has a first shank portion 3b of approximately the same outer diameter as the collars 4, 7, and a reduced diameter portion 3a on which the screw-thread 2 is formed.

Abstract: 836,505. Spindle brake arrangements for twisting machines. PRINCE-SMITH & STELLS Ltd. Aug. 1, 1958 [Sept. 2, 1957], No. 23556/58. Divided out of 836,470. Class 120(2) [Also in Group XXXIV] Each spindle 10 in a textile twisting machine has a rotatable brake ring 17 connected to it by a unidirectional clutch which transmits drive to the ring but allows reverse rotation of the spindle after braking has been applied so that, if a stop motion is operated, yarn may be unwound from the bobbin to prevent downward movement of the ring rail from causing yarn breakage. A scissors brake 18 co-operates with the ring 17 which is rotatable on a collar 15 fixed to the spindle 10. When the spindle rotates a roller 19 in a socket of the collar 15 is flung outwardly by centrifugal force to engage a radial face in a recess 171 of the ring 17 and transmits drive. After braking, the spindle may rotate freely in the reverse direction, the recess 171 being shaped to force the roller 19 within the collar 15. Two recesses 171 may be provided in the ring 17 to give positive drive in both directions, both being inoperative when the spindle is slowly rotated by the tension of the yarn as the ring rail moves downwards.

Title: Improvements in or relating to clamping devices for holding bags closed
IPC: B65D77/18
Filed: 1957-07-25
Abstract: 859,587. Closing bags. SCHUMM, E. July 25, 1957 [Aug. 4, 1956; April 11, 1957], No. 23579/57. Class 94(1). [Also in Group XXV] A clamping device for holding a bag closed, comprises two clamping strips connected to one another, one of the strips having a projecting rib 21 and the other strip having a slot 22 arranged so that in the clamping position, the rib projects into the slot, and the strips being provided with releasable fastening means for holding the strips together in the clamping position on the bag, the clamping strips being formed by a piece of synthetic plastic material and the projecting rib rendering one of the strips substantially rigid, the slot in the other strip being longer and wider than the rib. In the form shown the two clamping strips are joined together by a thinner section 20 so that they can be folded together. The fastening means consists of a stud 23 which has an annular groove 24 on the free end of one strip and a ring 25 on the free end of the other strip which is adapted to engage the stud 23 and be retained by the annular groove 24 when the device is folded about the portion 20 ; a projecting tongue 26 on the rib 25 aids the disengagement of the ring from the stud. The part having the rib is provided with the projecting rib 21 and this is received in the slot 22 in the other part so that a bag end placed over the rib is forced into the slot 22 when the ring is engaged by the stud. In a modification the ring and stud are omitted and instead the rib is formed at one end with a projection which engages over the end of the slot in the other part to hold the two parts in the folded condition. In this construction the ends of the strip are reinforced and projecting lugs are provided on each side of the slot so that when the end of the rib is hooked in the opening it is protected by the two lugs. Apertures for a wire, the ends of which can be sealed together by lead seal, can be provided in the ends of the strip.

Patent GB-360482-A (GB)
Title: Improvements in or relating to the manufacture of abrasive articles
Filed: 1930-08-07
Abstract: A composition for making a moulded abrasive article by vulcanization consists of a mixture of abrasive grains, a filler such as carbon black, and an aqueous dispersion of rubber containing a protective colloid which is dried to a moisture content of 5 to 7 per cent and then granulated.  Other materials which may be added to the mix are magnesia, lead acetate, and a preservative such as formaldehyde or borax.  The resulting dried product can be stored and moulded at any time.  In moulding, the mould is filled and heated to about 287 DEG F., and may be subjected to an initial moderate pressure followed by a short interval of high pressure, after which a lower pressure is maintained until partly vulcanized.  After this partial vulcanization, or "set-cure," the article is removed from the mould and vulcanized.  The high pressure may be maintained during the whole of the "set-cure".  In an example, 92 parts of abrasive grain of 16 grit, including a filler, are mixed with a dispersion of rubber containing a protective colloid of 8 parts (on a dry basis), and small proportions of lead acetate (10 per cent solution) and magnesium oxide added.  The abrasive may be silicon carbide, alumina, garnet, &c.  Specification 302,151, [Class 70. Indiarubber &c.], is referred to.

Title: Improvement in concentration of fat soluble vitamins
IPC: A61K31/59
Filed: 1944-11-29
Abstract: Fat-soluble vitamins, especially vitamin A contained in fish liver oils or fractions thereof, but including also the tocophenols, are concentrated by reacting a glyceride fat containing such substance with a primary or secondary monamine or diamine or a quaternary ammonium base, including substituted compounds such as ethanolamine or 1-amino-2-butanol, preferably under nitrogen or carbon dioxide and the separating the vitamin from the reaction products.  The temperature range preferred is from 80 DEG  to 150 DEG  C. with an optimum of 100 DEG  C. and reaction usually requires from about 2 to 20 hours to complete.  At least one molecular equivalent of amine should be used, based on the fatty acid content of the glyceride treated, and preferably a slight excess.  The reaction products may be treated with an acylating agent, e.g. acetic anhydride or acetyl chloride, to obtain vitamin esters prior to distillation, solvent extraction or filtration of the desired "unsaponifiable" fraction. Numerous examples are given.
