Title: Method of and device for gear teeth hardening
IPC: C21D7/02
Filed: 1973-03-02
Abstract: 1427093 Improving physical properties by bending ROSTOVSKY ORDENA TRUDOVOGO KRASNOGO ZNAMENI GOSUDARSTVENNY UNIVERSITET 2 March 1973 10223/73 Headings B3V and B3E [Also in Division C7] Gear teeth are hardened by plastically bending them in the direction of intended load. Departures from the desired shape due to bending are compensated for by a preliminary alteration to tooth shape or by subsequent machining. The teeth may be heated and cooled while subjected to the bending load and may be of carbon, or case-hardenable, steels. Apparatus for performing the method comprises a stationary ring with internal tapering grooves 9 to receive tapering anvils 8, and an arbor 16 for supporting the gear 4. A group of anvils is inserted in the ring and the co-operating gear teeth are bent against the anvils by turning the arbor by means of an hydraulic jack 22. A different group of teeth is treated at each operation. Curvilinear teeth may be bent using anvils which are in two or more sections mounted end-to-end, Fig. 3 (not shown). Instead of turning the gear, the anvil ring may turn. In another form, Fig. 5, the anvil ring 27 with insertable anvils 32 is contructed as an induction heater for the gear 4 and has a passage 33 for cooling liquid. In operation, the gear is turned to carry its teeth away from the anvils 32 before the heater is energized to heat the surface of the teeth to 150-250‹ C. above the hardening temperature. The ring is then secured between hydraulically operated jaws 31 and the mandrel 35 turned to bend the teeth against the anvils. During bending the teeth being treated are spray-cooled. After treating the rest of the teeth in groups, the gear may be tempered. Bending angles of 10-20 seconds are referred to. Pre-hardened teeth are heated only in the zone of the teeth fillets.

Transformers.-In apparatus comprising an X- ray generating device immersed in oil in a closed container, means are provided for de-energizing the generating device upon a predetermined volume change of the oil filling. As shown an. X-rav tube 6 and a transformer 7 are immersed in oil in a container 1. An auxiliary chamber 20,. communicating with the chamber 1 by a tube 21, has a diaphragm 22 of sylphon or other yielding material. The diaphragm 22 has a plate 23 with a projecting rod 24 which passes through a rigid plate 33 having a contact 31. A flexible support 35. having a contact 32 normally engaging thecontact 31, is arranged so that the rod 24 will engage with it after a predetermined compression of a diaphragm 22. In operation, an electric current passes through a conductor 25, a brush 27, an insulated ring 28 permitting rotation of the apparatus, contacts 31, 32, and conductors 35, 29, to the transformer primary 7, from whence it passes to the container 1. which is earthed.

Title: Missile system comprising a self-propelled missile and a laun ching device therefor
IPC: F41F3/04

Abstract: 1428063 Launching self-propelled missiles; missile launchers WEGMANN & CO 8 March 1974 [9 March 1973 20 Feb 1974] 10615/74 Headings F3A and F3C A system for launching self-propelled missiles in a manner whereby the error in the departure angle and the up and down oscillation of the missile nose during flight are kept to a minimum, comprises a launching device and a missile having guide means spaced along the length of the missile for supporting the missile in the launching device; wherein the guide means are arranged with respect to the centre of gravity of the missile and co-operate with the launcher such that at the velocity of the missile at the instant of leaving the launching device the nose of the missile will tilt forwards at an angular velocity which is at least substantially equal to the rate of change (γ 0 ) of the angle of inclination of the missile trajectory at the same instant. The guide means can be situated on opposite side of the centre of gravity, to the rear of the centre of gravity, or the leading guide means may be in the plane of the centre of gravity. The distances of the two guide means from centre of gravity of the missile are determined by the equation: where # 1 =γ 0  are equal to the speed of change of the angle of inclination of the missile at the instant free flight begins, # 0  is the angle of inclination of the missile axis to the horizontal upon leaving the launching device, I is the moment of inertia of the missile about its horizontal axis through the trailing guide means, G is the weight of the missile, L is the length of the ways in the launching device, b is the linear acceleration of the missile, a 1  and a 2  are respectively the distances of the trailing and leading guide means from the centre of gravity of the missile. The launching device may have a plain barrel or may have ways 5, Fig. 6, for the trailing guide means 2 and separate ways 4 for the leading guide means 1. The maximum tilting effect is obtained when, as shown, the ways 5 extend as far as the forward end of the ways 4. The tilting effect is reduced as the ways 5 terminate short of the forward end of the ways 4 and is nil when the ways 5 terminate at the rear end of the ways 4, since, in the latter case, the guide means 1 and 2 leave their respective ways simultaneously and the missile cannot therefor pivot about its trailing guide means under the action of gravity when the support of the leading guide means disappears.

Title: Improvements in and relating to steering apparatus for ships
IPC: B63H25/28
Filed: 1933-04-19
Abstract: 408,100. Ships' steering-gear. JACKSON, L. MELLERSH-, 28, Southampton Buildings, Chancery Lane, London.-(Etablissements P. Duclos ; Boulevard Sardou, Le Canet, Marseilles, France.) April 19, 1933, No. 11502. [Class 114.] A ship's steering-gear with hydro electric transmission comprises two sets of rams controlling the helm, two sets of pumps, an automatic bye-pass for each set, an automatic distributer common to both sets, a valve distributer for each set of rams and a spare set of pumps connected between the valve distributers of the service pumps, whereby any or all of the sets may be used. The service pumps J, J1 for starboard and port control are connected to rams Pb, Pt respectively through valves R, R1, which valves are coupled to an automatic control element E whereby according to the direction of flow of fluid from either of the pump systems the control unit E sets itself for setting the valves R, R1. When working fluid circulates in the direction of the arrows F, F1 the pistons p, p1 of the distributer E are pushed downwards and the slide valves T, T1 open so that the pressure acts on the pistons R, R1 of the bye-passes G, G1 holding them closed. If a break-down occurs in one of the sets, for example, the starboard set the pistons of the starboard rams are then driven by the port pistons and the slide valves T, T1 of the distributer E remain in the position shown, and due to the difference in pressure the working fluid then circulates in the direction indicated in Fig. 4 so that the piston R1 of the starboard bye-pass is drawn upwards and causes the bye-pass to open. The two cylinders of the starboard rams are thus put into communication with one another so that they rock freely under the movement of the pistons of the port rams. When the pumps are stationary the pistons of the distributer E take up an intermediate position under the action of their opposed springs and the byepasses remain closed under the action of their springs M until the pumps start to deliver again.
