Abstract: 531,446. Keratin ; moulding powders. BAKONYI, S. July 22, 1939, No. 21368. Convention date, Aug. 26, 1938. [Class 2 (iii)] Keratin-containing material is refined to make it suitable for incorporation in ureaformaldehyde or thiourea-formaldehyde moulding powders by treatment first with an oxidizing agent and then with a reducing agent, with or without a preliminary and/or final treatment with dilute acid. In an example meal or chips of hoofs or horn are treated with 1-2 per cent hydrochloric acid at 30-36‹C. for 12-24 hours, washed, treated with 1 per cent weakly alkaline hydrogen peroxide at 30-36‹C. for 12-48 hours, washed, treated with 0.8-1 per cent sodium hydrosulphite for 12-24 hours, washed, treated with 0.1-1 per cent formic acid and finally washed, dried and ground. A resin mix of urea (or urea and thiourea) formalin, ammonia (to neutralize) and ethylene diamine, to which may be added more urea or thiourea. to bring the ratio to formaldehyde to 1:1.75, is (1) mixed and kneaded with the refined keratin flour, the mass being extruded into rods which are dried and ground; or (2) mixed also with condensation products of formaldehyde and phenol or cresol and with hexamethylene tetramine ; or (3) the amount of keratin used in the first example may be increased but with addition of water. The Specification as open to inspection under Sect. 91 states that zinc chloride may be added to the acid for the treatment of the keratin, and that in example 1, to the condensation mixture before adding the keratin, there may be added phthalic anhydride or monoglyceride or adipic acid or monoglyceride in alcoholic solution. This subject-matter does not appear in the Specification as accepted.

Title: Virus or viral antigen purification method and vaccine producing method
Inventor: YAMAMOTO AKIRA
IPC: A61P31/12
Filed: 2000-03-20
Abstract: A method for purifying a virus or viral antigen is disclosed, by which a virus or viral antigen can easily and quickly be separated and purified from a culture solution or cellular emulsion containing the virus or viral antigen without lowering the activation of the virus or viral antigen. The purification method is characterised by comprising a process in that a sample containing a virus or viral antigen is contacted with hydroxyapatite as a solid carrier which is sintered at 400 through 1300{C and capable of absorbing a virus or viral antigen, and a process in that the virus or viral antigen absorbed by the solid carrier is eluted by using an eluant in a neutral pH range. In this case, it is preferable that the hydroxyapatite is formed of spherical porous particles. It is also preferable that a phosphoric acid-based buffer solution is used as an eluate. Further, a vaccine producing method using such a purification method is also disclosed.

Title: Directing cellular calls to a fixed line telephone
Inventor: CHEN STEPHEN
IPC: H04M1/725
Filed: 2001-01-05
Abstract: A switching control device for transmitting calls received by a cellular phone to a fixed-network telephone enables people to receive calls transmitted to a cellular phone by way of a fixed network telephone particularly equipped with a plurality of extension lines via conversion operations. It operates with a cellular phone/fixed network telephone switching device in cooperation with an on/off device. When a cellular phone receives an incoming call, the switching device will first detect the main telephone set and its extension lines of their individual status of use; and the on/off device is selectively actuated of its on and off states and also its vibration ring operation according to the detection. Thereby a user can pick up a nearest extension line without rushing back to a main telephone set when an incoming call is transmitted to a cellular phone.

IPC: A61H3/02
Filed: 2001-01-29
Abstract: A shock absorber mountable on the outside of a waking aid comprises a resilient mechanism 35 having at least one elastic component 24,25,26 wherein, the mount of tension and the degree of movement provided by the resilient mechanism can be varied. The shock absorber is fitted to the walking aid between one of the end projection 12 or 13 and a clip 29. The resilient mechanism 35 includes collars 14, 15 between the elastic components 24,25,26. Each elastic component 24,25,26 has a different size in cross section providing a different tension rating for each elastic component, such that the mount of tension in the resilient mechanism 35 can be varied by selecting a particular elastic component 24,25,26 or combination of components to be actively attached to the walking aid. Particular elastic components 24,25,26 are selected by using the clip 29 to fix the resilient mechanism to the walking aid at the collars 14, 15 or projections 12,13, thus in Figure 6 the resilient mechanism is shown fixed at projection 12 and projection 13 thereby selecting all the elastic components 24,25,26 for active use. The degree of movement within the resilient mechanism can be varied in a similar manner. The elastic components may be formed from coil springs, concertina shaped elastic material, a cylinder shaped elastic material or of strips of elastic material. The walking aid with the shock absorber fitted may be used to perform various exercises (Figures 10-23).

IPC: A01D33/08
Filed: 2001-04-10
Abstract: A method and means of classifying a succession of objects 13 moving along a defined path comprises causing the objects 13, one at a time, to strike an element 22 such that it vibrates. The properties of an incident object 13 are determined from a vibration characteristic of the struck element 22. The rate of decay of the vibration of the said element may be used. The detected properties are then used to select or reject each object 13. The defined path may be a conveyor 10. The struck element 22 may be a rod arranged partly in the path of the objects 13. The objects 13 may be agricultural produce such as a beet root crop. The classification system may separate good beets from deteriorated beet, stones and clods of earth.
