Title: Process for decarbu''sing chromium containing alloys
IPC: C21C5/28
Filed: 1972-02-28
Abstract: 1396317 Decarburizing alloys UDDEHOLMS AB 5 Oct 1972 [6 Oct 1971 28 Feb 1972] 46507/71 and 9162/72 Heading C7D A method of decarburizing alloys containing at least 10 wt per cent of chromium together with a major proportion of iron, cobalt and/or nickel, comprises introducing oxygen to form carbon monoxide with the carbon, and simultaneously or subsequently introducing sufficient steam and/or ammonia to lower the carbon monoxide partial pressure below the equilibrium pressure for oxidation of carbon or chromium while keeping the volume ratio of oxygen to steam/ammonia below 3:1. The alloys refined may be stainless steels or nickel- or cobaltbased alloys. The temperature of the decarburization should be 1550-1800C, which may be achieved by oxidation of any silicon present in the melt; any chromium which is oxidized collects in a slag and may be recovered with ferrosilicon reductant. The refining is performed in a converter provided with coaxial inlet tubes, the inner tubes admitting oxygen, and nitrogen/argon as scavengers after the decarburization, while steam is passed through the outer tubes.

Title: Time delay control device for tissue processing machines
IPC: G04F3/08
Filed: 1958-03-21
Abstract: 829,517. Preparing microscope specimens. TECHNICON INTERNATIONAL Ltd. March 21, 1958 [April 8, 1957], No. 9225/58. Class 97(1) [Also in Group XXX] In automatic immersion apparatus for the preparation of histologic tissue for microscopic examination of the kind in which provision is made for a twenty-four hour clock-controlled timing cycle, a time delay control device is provided which can be set to introduce a delay period prior to the start of the processing cycle or during it. This device may be controlled by the clock mechanism which controls the processing operations. This clock operates continuously and its working is not interrupted by the operation of the time delay control device. The immersion apparatus 10, Fig. 1, is driven by an electric motor 18, Fig. 8, which is controlled by clock timing mechanism 20 comprising a conventional electric clock motor 24, Fig. 3, which rotates a twenty-four hour timing disc 26 and a disc 104 carrying a cut-off pin 128. The motor 24 drives also a time delay control device 32 which delays the start of the processing operation for a predetermined time. The clock-driven shaft 30 is connected by gears 34, 36 having e.g. a ratio of 1 to 3 to a gear 46 of the same size as the gear 36 which is free on a shaft 48. This shaft extends through a panel 22 and is secured thereto by nuts 50, 52, Fig. 3. It is provided with a flange 54, which bears against the hub 56 of the gear 46, and a cam disc 60 which is maintained by the lock nut 62 in relatively tight frictional engagement with a spring spider 58 placed between it and the gear 46. A depression 64 in the disc 60 receives a roller 66 mounted on a normally closed master switch 68. A dial 79 calibrated in hours fits loosely on the shaft 48 and is fixed to the front of the panel 22 by means 80 which acts also as a stop for a knob indicator 82 fast on the shaft. The disc 26 has notches 108 in its periphery to provide determined time sequence of operation of the motor 18 and is marked with intervals of ten minutes. The motor is controlled by a pivoted arm 112 carrying a pin 110 which rides on the periphery of the disc 26 and moves in and out of the notches 108. The arm 112 is in contact with the operation element 124 of a microswitch 116 in the circuit of the motor. The lever 74 carrying the roller 66 is provided with a cross-piece 78 which bears on the underside of a pivoted rocking lever 138 and raises it from the position shown in Fig. 5 to that shown in Fig. 8 as the disc 60 rotates. In the former position, the pin 110 is engaged by a notch 142 in the lever and is prevented from moving into the notches 108. There is, therefore, no delay setting to delay the operation of the apparatus. A pin 136 is provided on the lever 138 for moving it by hand. A cut-off arm 126 is pivoted at 129 on the panel 22 and is moved by the pin 128 on the disc 26 to engage the pin 110 and thereby discontinue the processing operation. Specifications 697,162, 752,484 and 780,793 are referred to.

Title: Improvements in or relating to modulated carrier wave systems
IPC: H03B5/18
Filed: 1936-03-30
Abstract: 454,709. Valve modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Lindenblad, N. E. ; Port Jefferson, Long Island, New York, U.S.A.) March 30, 1936, No. 9429. Convention date, March 30, 1935. [Class 40 (v)] Frequency modulation is effected by varying the phase and/or amplitude of energy fed back from the output circuit of an oscillator to its frequency determining circuit. The push-pull oscillator valves 6, 8, Fig. 1, have their grid circuits coupled through loops 10, 12 to a frequency determining line 14, 16. Energy from the anode circuit 48, 50 is fed in push-pull to the grids of valves 68, 70 which are also fed in similar manner with the modulating potentials from a transformer 100, while their anodes are connected together and to a tuned loop 84 one end of which is connected to a capacity element 94 facing the end of the quarter wave line 14, to vary, at signal frequency the constants thereof and hence produce frequency modulation of the oscillator 6, 8. The carrier energy may alternatively be supplied to the tuned cathode circuit of valves 68, 70, while the line 14 may be influenced by an inductive loop instead of the capacity element 94, Figs. 2 and 3 (not shown). In a further embodiment, Fig. 6 (not shown), the modulating potentials are applied in push-pull to the anodes of the valves 68, 70 which, for carrier frequency, are connected together and to the control circuit. A system is also described having single oscillator and modulator valves, Fig. 7 (not shown), and also one in which a signal component is applied in addition to the oscillator anodes to correct for power variations introduced when modulating over a wide frequency band, Fig. 8 (not shown). In the system shown in Fig. 4, the frequency of the push-pull oscillator 500 is determined by a half wave line 302 and energy from the output circuit is fed back from a coil PU to two push-pull pairs of valves 508, 510 each pair forming half of a push-pull system supplied from the modulating source 100, the anode being connected as shown to an auxiliary half-wave line 504 coupled to the line 502 and which is stated to vary the effective inductance and capacity of the latter at signal frequency.

Title: Alarm timepiece
IPC: G04C21/20
Filed: 1975-03-07
Abstract: 1474323 Alarm clocks SEIKO KOKI KK 7 March 1975 [8 March 1974] 9580/75 Heading G3T [Also in Division H1] In a clock having an alarm rendered operative when a timing wheel is in a particular angular position relative to a manually adjustable detecting member, a further manually operable member is provided actuation of which advances the detecting member by a constant amount e.g. corresponding to five or ten minutes. As shown the alarm is a buzzer 43 connected in series with a manually set switch 42 and with two sets of contacts which are respectively closed in particular positions of hour wheel 14 and tens of minutes wheel 11. The latter is intermittently advanced by teeth 10 on a units of minutes wheel 8 and has teeth 13 which similarly advance the wheel 14. The wheels 11, 14 are rotatably mounted on respective shafts 4, 5 and carry bridging contacts 35, 36 which co-operate with the inner arms of four-armed contact members 16, 18. The latter are also rotatably mounted on the shafts 4, 5 and are coupled to alarm time indicating wheels 17, 19 carrying digital indications which are visible in a window 25. The alarm time is set by a knob (27), Fig. 1 (not shown) on the wheel 17. The outer arms of the contact members run on semi-annular fixed contacts 31-34 which are connected to the alarm circuit and to a power source 41, e.g. a battery. Depression of a pin 54 causes a lever 45 to pivot about pin 46 against the bias of a spring 51. A pawl 47, mounted on a pivot pin 50 on the lever and biased by a spring 52, is thus brought into engagement with a ratchet wheel 44 on the wheel 17, advancing the wheel by ten minutes. Since this advance can also turn off the alarm the pin 54 serves as a "drowse" actuator. A blocking member (65), Figs. 5, 6 (not shown) may be provided, which is manually operable to open the alarm circuit and prevent actuation of the pin 54. The alarm may alternatively be controlled by a single switch actuating member (59), Fig. 6 having two arms co-operating with detecting members which are respectively displaced axially when the timing wheels 11, 14 are in particular positions. The actuator (59) thus moves as a whole only at the alarm time to close the switch. The clock is driven by a partially toothed pinion 6 attached to a synchronous motor. The time display is controlled by further contacts carried by the wheels 8, 11, 14 and co-operating with fixed contacts (68-70), Fig. 1.

Title: Improvements in or relating to electron discharge devices of the electron velocity modulation type
IPC: H01J25/08
Filed: 1944-01-21
Abstract: 587,664. Velocity-modulated tubes ; wave guides. STANDARD TELEPHONES & CABLES, Ltd., and TOMLIN, S. G. Jan. - 21, 1944, No. 9652/46. Divided out of 587,619. [Classes 39 (i) and 40 (v)] An electron discharge device of the type described in Specification 537,490, in which an electron beam is projected across a coaxial line resonator, comprises a glass envelope 7, Fig. 1, enclosing the resonator and an annular copper disc 6 sealed through the envelope 7 and to which the resonator ,1 is secured. Fins 2, 3 attached to the resonator 1 and fins 4 attached to the central conductor 5 define a slot for the passage of the electron beam. The resonator may be open at the upper end as shown, in which the generated waves are radiated directly therefrom. The diameter of the open end is preferably less than the cut-off diameter at the operating frequency. Alternatively, the upper end of the resonator may be closed, and energy extracted by means of a wire loop and probe from the dosed end, Fig. 3 (not shown). The lower end of the resonator may be left open in this case if the diameter of the resonator is below the cut-off diameter. Such a device may be coupled to a wave-guide or coaxial line by assembling it through a hole in the wall thereof, Fig. 4 (not shown). The device is in this instance preferably provided with electronic tuning as described in Specification 587,619. The device may be provided with mechanical tuning to supplement the electronic tuning, Fig. 5. The central conductor 23 is capacity coupled to the central conductor 5 of the internal resonator 1 by means of a rod 24 terminating in a metallic plate 25 which is sealed through the cup-shaped portion 8 of the envelope 7. The external resonator is provided with a tuning piston 22. Energy is extracted by means of a coaxial transmission line 26. The device may be mounted inside a cylindrical metal tube 28, Fig. 6, having two diametrically opposite apertures 30 therein so that the poles of a focusing magnet (not shown) can be brought close to the envelope 7. The metal tube 28 is provided with a flange 31 to which is screwed an annular disc 32. The copper disc 6 is sandwiched between the elements 31 and 32, being insulated therefrom by mica washers 33, 34 respectively. A slot in the disc 32 is provided, Fig. 7 (not shown), for holding a pin so that the correct orientation of the electron beam with respect to the magnetic field may be obtained. This assembly may be used in the arrangement of Fig. 5. Alternatively, a cylindrical metal sleeve 36 may be attached to the rod 24 as shown and serves as an antenna,. The device may then be arranged so that the antenna 36 projects through a circular hole in the side of a resonator of rectangular crosssection, Fig. 8 (not shown). The latter resonator is closed at one end by a tuning piston and at the other end is provided with an apertured diaphragm. A flange is provided at the end adjacent to the diaphragm for coupling the resonator to a wave-guide,

Title: Improvements relating to presses
IPC: F16P3/04
Filed: 1938-03-31
Abstract: 513,083. Hydraulic presses. FINNEY, J., and MOORE, G. E. March 31, 1938, Nos. 9811/38, 16846/38 and 6651/39. [Class 69 (ii)] A down-stroke hydraulic press is fitted with a safety locking bolt which automatically comes into operation to prevent the main ram from performing an inadvertent full downward stroke after it has been raised, means being provided to move the locking bolt out of the locking position when the control means is operated normally and the press is in the correct condition for working. In the form shown in Figs. 2 and 3, the platten 6 of the main ram 7 carries a rod 8 which is slotted at 8a to receive a bolt 14 which is pivoted to a spring-pressed yoke 13 carried by the rod 12 of a control piston 11 within a cylinder 10. The latter is connected by a passage 10d to the cylinder 19 of the main ram and with the atmosphere by means of a bye-pass passage 10a controlled by a spring-controlled valve 16, said passage 10a also communicating by passages 10b and 10c to the hydraulic reservoir 17, Fig. 1, and the exhaust side of the cylinders 18 of the auxiliary lifting rams, respectively. When the press is to be operated, the cylinders 18 are connected by valve means A to the reservoir 17. The liquid closes the valve 16 and cuts off the cylinder 10 from the atmosphere. The permissible falling motion of the main ram 7 therefore causes the piston 11 to move against the spring 15 to release the bolt 14 and allow the main ram 7 and platten 6 to fall through the full operating stroke. In a modification described in detail in the Specification, suitable for use in case a quantity of air may accumulate or become trapped in the cylinder 19, the outer end of the yoke 13 carries a ram which operates in a cylinder 21 and is acted upon directly by liquid from the auxiliary cylinders 18. The pipe line 23 leading from the cylinder 21 to the reservoir 17 carries a housing 24 for a spring-pressed non-return valve which operates a plunger 27. The latter engages a release lever 28a, which carries a blade spring 29 in the path of a block 30 on a rod 31 fixed to a vertically displaceable wire mesh guard 32. By this means, if the guard is not lowered, liquid cannot pass from the cylinder 21 to the reservoir 17, and the bolt 14 cannot be operated to free the main ram.

Title: Means for controlling the tension of a web
Inventor: JEANS MICHAEL ANTHONY
IPC: B65B41/12
Filed: 1964-03-09
Abstract: 1,032,074. Feeding webs. PRINTING, PACKAGING & ALLIED TRADES RESEARCH ASSOCIATION. March 2, 1965 [March 9, 1964], No. 9837/64. Heading B6B. A web tension sensing device comprises a fixed bar 2 formed with a central duct 6 which is connected to an external source of fluid pressure via a pipe 7. The duct 6 communicates via a restricted passageway 8 and a chamber 9 with a shallow recess 10 formed in the surface of the bar 2. A fluid pressure cushion 33 is formed between bar and the travelling web 1. Variations in web tension produce pressure variations in the fluid pressure cushion 33 and these pressure variations are sensed by a spring-loaded slide valve via a pipe 12 communicating with the chamber 9. The slide valve has a spindle 15 with four lands 16 which co-operate with five annular recesses 14a to 14e. The two outside recesses a and e act as exhaust ports and the centre recess c acts as an inlet port or conversely. The lands and recesses are arranged so that any two adjacent pairs of recesses communicate for a particular position of the spindle 15. Recesses b and d communicate with a piston-cylinder arrangement 28 via pipes 26 and 27 which actuates a brake shoe arrangement as shown. The pipes 26 and 27 may communicate with a controller for a motor, such as an hydraulic motor, which drives web feeding devices or a web-roll spindle. In an alternative sensing device, Fig. 2 (not shown), the shallow recess 10 is filled with a porous-material insertion 58, such as sintered bronze, so that the restriction 8 is not required. Variation in the pressure of the cushion may be detected with a diaphragm 60, one side of which is in direct contact with the fluid pressure cushion, the other side of which is in communication with a constant pressure source via a restriction 63 and a nozzle 61, so that the diaphragm will act as a " flapper valve." The pipe 65 communicates with the slide valve. For flimsy material webs such as paper webs, the fluid medium may be air and with webs of a material such as metal the fluid medium may be a liquid such as oil.
