Title: Process for welding ferrous metal
IPC: B23K31/02
Filed: 1937-01-11
Abstract: 493,927. Welding tubes &c. BROADFIELD, W. H. Jan. 11, 1937, No. 755. Void. Convention date, Jan. 13, 1936. [Class 83 (iv)] In welding ferrous metals such as the longitudinal seams of tubes, the surfaces to be welded are subjected to an oxidizing heating prior to welding. In making tubes, a flat or curved strip is conveyed from an oven to a heater where it is first subjected to an oxidizing heating by the introduction of oxygen preferably by use of compressed air mixed with pure oxygen or of commercially impure oxygen, which contains 80 per cent of oxygen. After heating, an inert gas such as nitrogen mixed with a reducing medium such as finely powdered sulphur, boric acid, silicic acid or their salts, is blown under pressure on to the parts to deoxidize the heated area. Sulphur may be used in admixture with a liquid hydrocarbon such as gas oil. The edges are them welded by pressure and the tube passed through finishing rolls and then through a tunnel kiln into which a cooled inert gas flows.

Title: An improved method of obtaining iron and tin from tin scrap
IPC: C22B25/06
Filed: 1920-01-09
Abstract: Tin scrap is treated with oleum to dissolve the tin, and the material is then lifted out of the acid and washed in water. Fresh acid is added to replace that used and another batch is treated.  After a time a basic sulphate SnSO4.SnO2 deposits and is drawn off.  The washing-water contains some insoluble oxide, SnO2, and some tin in solution.  The dissolved tin is recovered by precipitation as sulphide or iron is added to neutralize the acid and obtain metallic tin.  External heat is not required in the process, but the acid bath is maintained by the exothermic heat and the periodical additions of fresh acid at a fairly constant temperature of 45-55 DEG  C. and a strength of about 10 per cent free sulphur trioxide.

Title: Textile fibres comprising poly 1,4-cyclohexylene dimethylene terephthalate
IPC: C08K3/30
Filed: 1971-01-07
Abstract: 1322481 Textile fibres comprising poly(1,4- cyclohexylene dimethylene terephthalate) EASTMAN KODAK CO 7 Jan 1971 [9 Jan 1970] 832/71 Heading B5B [Also in Division C3] Textile fibres are obtained by adding to poly- (1,4-cyclohexylene dimethylene terephthalate), by any conveienent means prior to final extrusion, 0À3% to 6À0% by weight, of precipitated barium sulphate, the fibre then being extruded and subsequently processed in the conventional manner, for example to produce staple fibres of continuous filaments suitable for use in carpets. Fibres made by this method have improved soilholding properties. and the fibres can be made in any desired cross-section. Fibres produced by this method avoid the chalky appearance before and after dyeing and thus it is possible to provide a single lustre fibre and eliminate the need for a blending step in making spun carpet yarn from the polymer. The average size of the barium sulphate particles is 0À8 microns. The optical brightener, a fluorescent compound 4-41- bis(benzoxazol-2-yl)stilbene is used in some of the Examples.

Title: Mobile communication method
Inventor: MASUDA HIROYO
IPC: H04W8/02
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To permit subscriber control even on a roaming disabled network by accepting position registration at a home location register only when it is reported to the home location register that a mobile terminal cancels the registration of an auxiliary service related to a roaming request through the subscriber control. SOLUTION: When a mobile terminal MS is moved to another home network and the first position registration is requested through a mobile exchange MSC inside the previous network, on the condition that roaming is possible, subscriber data are sent to the mobile exchange MSC. The mobile exchange MSC reports this to a home location register HLR. The home location register HLR reports 'position registration refusal' to the mobile exchange MSC while adding the detailed reason. The mobile exchange MSC starts a timer for waiting the subscriber control and reports the 'position registration refusal' to the mobile terminal MS. When roaming is still requested, the mobile terminal MS requests the inactivation of an auxiliary service S8 through the subscriber control.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the unauthorized recycle of a disposable camera by disabling one of camera functions such as an electronic flash, when the frame counter of the camera shows the attainment of the maximum frame number of a film roll in the camera. SOLUTION: In order to initialize a counter 55 and restore an electronic flash function for enabling the authorized reuse of a camera loaded with a new film roll, a reset code needs to be inputted to the camera via a code input device 57. This code input device 57 reads out a recognition code saved in an IC 51 built into the camera, and further reads out a corresponding reset code from a lookup table 69 for the output thereof to the IC 51. If a function application code saved in the IC 51 does not agree to the reset code, the electronic flash function is permanently invalid, or cannot be restored over the prescribed period.

IPC: B21C47/34
Filed: 1984-01-06
Abstract: PURPOSE:To prevent a steel strip from generating ear breakage and ear flaw at its top and causing meandering by bringing liners mounted on guide surfaces to be in contact with the strip into tight contact with the strip in confirmity with its width. CONSTITUTION:A load cell 5 detects the passing of the top of a steel strip 2 through a final stand 11 to transmit its detection signal to a control device 6 thereby transmitting further this control signal to a side guide 3. Then the guide 3 projects rolls 33 from liners 32 mounted on the guide surfaces 31 to conform the distance between the rolls 33 to the width of strip 2. The rolls 33 are brought into contact with the edges of strip 2 when the top of strip 2 passes the guide 3. In the same manner, a control signal is also transmitted to the guide 3 from the device 6 when the bottom of strip 2 passes the stand 11. In response to this control signal, the guide 3 retreats the rolls 33 behind the liners 32 mounted on the guide surfaces 31 to conform the distance between the liners 32 to the width of strip 2. And then, the liners 32 are brought into contact with the strip 2 to prevent its meandering by holding the bottom of strip 2 between both liners 32 with the aid of a frictional force between them.

IPC: B29C45/38
Filed: 1985-11-14
Abstract: A sprue part is cut and removed from the injection mold part during the manufacture of information storage disks by an injection molding process. The highly sensitive molding of an information storage disk is protected from damage by the sprue and the deposition of dust particles during stripping by this process. The sprue is punched into a part serving as the die of the injection molding tool and subsequently removed, in particular by suction, through an orifice leading from inside the part, together with the dust particles generated in the punching process. Preferably, the sprue is punched out and removed with the injection molding tool closed. The injection molding tool must be opened only after the sprue and the dust have already been removed, thus ensuring that the molded product has an especially good quality.
