Title: Improvements in and relating to the carburization of ferrous metals
IPC: C23C8/22
Filed: 1927-08-25
Abstract: 276,675. British Thomson-Houston Co., Ltd., (Assignees of Hegel, G. W., and Brophy, G. R.). Aug. 26, 1926, [Convention date]. No Patent granted (Sealing fee not paid]. Cementation.-In a method of carburizing ferrous metal articles, more especially articles of low carbon steels, the articles are heated in a retort to a temperature above the recalescence point and a liquid or mixture of liquids which when vaporized provide not only the carburizing gas but also another element which assists the cementation process is supplied to the retort at such a rate so as to maintain a uniform gaseous atmosphere around the articles, air being excluded. The liquid supplied may consist of bone oil or a mixture of petroleum &c. and bone oil, cotton seed oil or oil of mirbane (nitrobenzene). A suitable mixture, is 8 parts of bone oil, 8 parts of kerosene and 2 parts of oil of mirbane. The articles are placed in a retort 10 mounted in an electrically-heated furnace, 14, the flange 13 of the retort resting on the edge of the throat 11 of the furnace. The furnace is provided with an insulated cover 15 comprising a plate 17 secured to a casing 18 filled with insulating material 19. A pipe 20 to which is secured a short pipe 21 is provided in the cover 15 to act as a vent. The cover 15 fits in a sand seal 22 provided on the top of the furnace. The carburizing liquid is fed from a tank 24 through a flexible pipe 25 to a nozzle 26 which is water cooled. The cover 15 may be removed by means such as the arm 32 &c. similar to that described in Specification 255,479, [Class 51 (ii), Furnaces and kilns for applying &c.]. During the carburizing process, the temperature, usually about 1700 F. is maintained fairly constant, preferably by means of suitable automatic mechanism associated with the electric heating circuit. After the desired cementation has taken place, the supply of carburizing liquid is cut off and the charge is heated for a predetermined time. The charge may then be quenched or allowed to cool slowly and then heated and quenched.

Abstract: 785,954. Cigarette lighters. REUGE, G. Aug. 12, 1955 [Aug. 14, 1954], No. 23325/55. Class 75(3) [Also in Group XXXVIII] In a lighter containing a spring-driven musical movement the winding is effected by displacement of the pivoted wick cover. In the arrangement shown in Fig. 1 the spring is wound by the lighter-actuating lever 4 depressing a rod 7 and partially rotating the spindle 9 through arm 8. In an alternative arrangement the arm 8 is replaced by a rack and pinion. In a further arrangement similar to that shown in Fig. 1 the spring is wound when the cover is closed, the upper end of the rod 7 being attached to the lighter cover by a pin slidable in slots in the cover. In the arrangement shown in Fig. 4 the rod 7 on being depressed rotates a lever 17 about a pin 18 to wind the spring attached to a ratchet wheel 24, through an arm 21, pivoted about a fixed axle 22, a pawl 23 and a link 20 attached to the lever 17. A spring 19 returns the lever 17 to the normal position when the lighter-actuating lever 4 is released. The musical movement is released by the rod 7 depressing a lever 26 at the end of its downward travel. To prevent the spring being overwound in the event of the lighter not being ignited on the first actuation the spring is fixed to a ring, frictionally in contact with the wall of a barrel containing the spring.

Abstract: 858,952. Indicating-apparatus. FERRANTI Ltd. July 21, 1959 [July 21, 1958], No. 23375/58. Class 106 (4). Apparatus for measuring the ratio of two quantities each represented by the frequency of a chain of electric impulses comprises a solenoid - operated ratchet 25 arranged to rotate a driver 20 in one direction in accordance with one quantity so that, when it engages a follower 19, an input shaft 17 and a pointer 13 are rotated, and trip means operated when a predetermined number of impulses representative of the other quantity have been received, firstly to rotate the input shaft 17 in the opposite direction to bring the follower 19 into engagement with the driver 20, if not already engaged and, immediately afterwards, to reset the driver 20 to a datum position by rotation of the driver 20 in the opposite direction. Assuming initially that the driver 20 is in its datum position with the follower 19 in contact therewith and the pointer 13 at the zero mark of the scale 12, impulses applied to terminal 11 will drive the pointer step-by-step, through solenoid 23, ratchet 25, driver 20 and follower 19, until a ratchet 35 has made a complete revolution, being driven in steps through solenoid 33 fed with impulses at terminal 10 in accordance with the second quantity. A cam 37 then closes contacts 40 to energize motor 41 which through friction wheels 46, 47 tends to drive the follower 19 backwards into contact with the driver 20. The pawl engaging the ratchet 25 prevents the driver 20 from being driven backwards and slipping occurs at

Abstract: 1,242,601. Vehicle steering mechanism. MITSUBISHI JIDOSHA KOGYO K.K. 17 May, 1968 [22 Aug., 1967; 2 Oct., 1967], No. 23724/68. Heading B7H. Lag reducing means for vehicle steering mechanism comprise a piston 62 dividing a bore 64 in a cylinder member 44 into two chambers which are filled with oil and communicate through respective passages 72, 74 with further oil chambers 76, 78 interconnected by a throttle orifice 82. Springs 70 arranged on either side of the piston 62 urge the piston into a central position in the bore 64. The cylinder member 44 is connected by a ball-joint 48 to the drop arm 18 of steering gear 12 actuated by a steering wheel 14. The piston 62 is connected through a rod 60 to the spool 58 of a control valve 30 which regulates supply of pressure fluid from a pump 34 to a steering ram 32. The spool 58 slides in a valve housing 42 carried by a cylinder member 36 which slidably supports the cylinder member 44 and is connected to a link rod 20 connected through tie rods 28 to steerable wheels 24. When the steering wheel 14 is rotated slowly oil is displaced between the chambers 76, 78 through the orifice 82 to permit relative movement between the cylinder member 44 and the piston 62 so that the response of the control valve is delayed. When the steering wheel is rotated rapidly pressure increases on one side of the piston 62 due to restricted flow through the orifice to produce a relatively fast response and a reduction in lag during rapid turns. This effect may be enhanced if the rate of pressure build-up on one side of the piston is increased by providing a vane-type pump 114 which is driven from the steering shaft 16 through gears 110, 112 and arranged to transfer oil from one chamber 76, 78 to the other as the steering wheel is rotated. In another embodiment, Fig. 7 (not shown), the control valve (30a) is actuated in response to axial movement of the steering shaft through lag reducing means (22a) and a lever 144. In a further embodiment, Figs. 8A, 10 (not shown), the lag reducing means (22b) is of the rotary vane-type and not of piston-and-cylinder type. In Fig. 4 (not shown) the lag reducing means is applied to steering mechanism not provided with power assistance.
