Title: Improved combination hair curling and hair waving appliance
IPC: A45D2/12
Filed: 1930-10-28
Abstract: 358,749. Hair curling and waving appliances. GREEN, (nÚe STRANGE), M., 62A, Hornby Road, Blackpool. Oct. 28, 1930, No. 32309. Grant of Patent opposed. [Class 131.] A combined hair curling and waving appliance comprises a short small diameter tube b of compressed paper, celluloid, or other light material, and a length of elastic cord a which is applied to the tube so that two separate portions of the cord lie alongside the exterior of the tube, one portion being shorter than the other, the cord also extending a distance beyond one end of the tube and being provided with means, such as a peg d, for engaging the other end of the tube. The longer and shorter portions of the cord a may be obtained by passing the cord through perforations b3, b<1>, b<1>, b<2> as shown, the perforation b<3> being nearer the end of the tube than the perforation b<2>. In a modification one of the perforations b<1> is omitted, the cord passing from the perforation b<3> to the end of the tube and then through the interior thereof to the other perforation b<1>. In use, the longer portion of the cord is used for curling, the end of a tress of hair being passed between the tube and the cord and rolled up upon itself, the free portion of the cord being then passed over the roll and the peg d inserted in the end of the tube. For waving, the tress of hair is passed completely beneath the shorter portion of the cord so that the tube lies against the head, the tress is rolled upon that part of the tube not covered by the shorter portion of the cord, and the free end of the cord is then applied as before.

IPC: F16B39/38
Filed: 1920-11-17
Abstract: 156,084. Ravier, L. Dec. 24, 1919, [Convention date]. Locking nuts.-A nut-loch comprises a nut, a counter-nut or ring engaging the nut and a split conical ring engaging a conical recess in the counter-nut. In the construction shown in Fig. 1, the nut 5 has a screwed outer part and a split conical portion. A nut 6 screws on to the nut 5 and has a conical part to engage the split cone and compress it upon the bolt 1. A split conical ring is screwed upon the bolt into engagement with a conical recess in the nut 6. In the form shown in Fig. 6, the conical portion on the nut 5 is dispensed with and a conical split ring 7 is forced into engagement with the bolt by a cone surface on the nut 6. A split spring washer may be arranged between the nuts 5, 6. In another construction, Fig. 8, a split and slit conical projection or ring over the nut 5 is engaged by a conical recess in the nut 6 which screws upon the bolt or upon the nut 5, and a conical split cone engages a corresponding recess in the top of the nut 6. In other forms, the nut 6 is split and provided with a depending cone which is wedged between the wall of a recess in the nut 5 and a split conical ring on the bolt; or the nut 6, in place of engaging the bolt, may screw into the recess in the nut 5. In the construction shown in Fig. 14, each nut 5, 6 has two slits 35, 36 and 37, 38 and the meeting faces of the nuts may be plain or coned. One such nut may be employed in connection with an ordinary nut and locked bv means of a split conical ring engaging a conical recess in the slitted nut. In place of slits, the locking nut may be provided with a resilient spiral extension 39, Fig. 16, and may be employed either as nut or oounternut or both; when employed as a counternut, it has a conical recess to receive the split conical ring. The Specification as open to inspection under Sect. 91 (3) (a) comprises a number of other constructions. In the form shown in Fig. 20 (Cancelled), the nut 6 screws upon the nut 5 and has a conical part to engage the slotted and slitted conical end of the nut 5 and also has its end slotted, slit and coned to engage a conical recess in the base of the nut 5. Fig. 26 (Cancelled) shows a form in which a slotted and slitted cone arranged on top of the nut 5 has a screw engagement with the nut 6, a conical part on the nut 6 engaging and compressing the cone on the bolt. Two split conical rings reversely arranged may be engaged by the nuts 5 and 6 respectively, these nuts being screwed one on the other. In the construction shown in Fig. 30 (Cancelled), the nut 6 engages both the bolt 1 and the nut 5 and has a split conical portion adapted to enter a conical recess in the nut 5. In a modification the male cone is formed on the nut 5 and the recess in the nut 6. Both nuts 5 and 6 may screw upon the bolt only and a split cone on one nut engage a recess in the other nut. As shown in Fig. 34 (Cancelled), nuts 5 and 6 are identical in form and each has a conical part 10 provided with a slit 11. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,138,259. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 14 July, 1967 [21 July, 1966], No. 32465/67. Heading H4K. In multifrequency code-signalling, e.g. between exchanges, pairs of digits are transmitted simultaneously, one in a 2-out-of-5 code, the other in a 2-out-of-6 code, 11 frequencies being employed in all. There are thus 5 surplus frequency pairs available in the second group, and these may be used in combination with 2 frequencies of the first group for supervisory and other special purposes. When signals are sent in immediate succession, as in the arrangement of Specification 1,030,188, a 4-frequency repetition signal is sent when a pair of digits are repeated. Also, when an odd number of digits are to be sent, the single final digit is supplemented by a surplus frequency pair from the second group.

Title: Improvements in or relating to meringues or meringue-like products
IPC: A21D13/00
Filed: 1961-09-12
Abstract: A food composition of rigid, aerated structure, particularly suitable for meringues and meringue-like products, consisting of an oil or fat composition-in-protein composition dispersion is prepared by aerating an aqueous soy-protein composition to produce a stiff foam, admixing the stiff foam with an edible oil or fat, agitating the admixture to disperse and to distribute the oil throughout the foam, and heating the admixture retainingly to entrap globules of the oil or fat within the foam.  The proteinaceous composition is preferably formed of soy protein (especially the modified soy protein composition disclosed in U.S.A. Specification 2,844,468), egg albumen and a whipping agent such as sodium hexametaphosphate, triacetin, or tri-ethyl citrate. Examples are directed to the preparation of food compositions from stiff foams composed of soy protein, dried egg albumen, sugar, and water, and corn oil or hydrogenated cottonseed oil; flavouring and colouring ingredients may be included. According to one example (1) portions of the oil-in-protein dispersion are moulded to provide pie-shell-shaped receptacles and are then dried for an hour in an oven at 300 DEG  F.; the shells may be used for serving creamed chicken or ice-cream.  In further examples (2 and 3), portions of the dispersion were dried (without moulding) to produce a snack item.  It is stated that the egg albumen may be replaced by carboxymethylcellulose, pectin, wheat germ, starch, or other suitable substance (defined). Specifications 922,751, 937,564 and 937,566 also are referred to.
