Title: Apparatus for securing knife edges and knife edge bearings of weighing apparatus on to the part on which they are mounted
IPC: G01G21/08
Filed: 1927-01-26
Abstract: 282,999. Berkel, W. A. van. Jan. 26, 1927. Moulds.-Apparatus for use in the securing of knife-edges or knife-edge bearings in weighing- apparatus by pouring molten metal between the elements comprises a frame having means for positioning the bearing elements in slots in a weigh-beam or other part that is clamped to the frame during the operation. A beam 1 is clamped to a frame 5 by brackets 12 and screws 13. Knife-edges 4 are positioned in slots 2 in the beam by the provision of V-notches 5<1>, 8<1> in the frames and brackets respectively, those parts in which the notches are formed being mag. netized to retain the knife-edges in position. Apertures 3 connect the slots to the opposite faces of the beam for the passage of the molten metal. Funnelled apertures 15 are provided in the frame to register with the apertures 3 in the beam and form pouring passages for the metal when the frame is inverted. Cooling air is passed through orifices 5<11>, 8<11>. communicating with the notches, to prevent undue heating of the hardened part of the knife-edges.

Title: Means for transmitting electrical signals between relatively-movable objects
Inventor: ROBERTS LESLIE
IPC: C10B41/04
Filed: 1959-01-23
Abstract: 863,294. Inductive signalling. SIMONCARVES Ltd. Dec. 31, 1959 [Jan. 23, 1959], No. 2530/59. Class 40(5) Means for transmitting alternating currents of two different frequencies, between two relatively movable objects comprises a pair of main inductances associated one with each object, a pair of secondary inductances also associated one with each object the two frequencies being applied to one each of the main and secondary inductances respectively, and thereby induced in the corresponding halves of the pairs when they are in mutual alignment. In the embodiment described, applied to the operation of a coke oven battery, stations 2, 3, Fig. 1, at opposite sides of the battery 4, are inductively coupled by auxiliary coils 27 and connections 28. A visual indicator of alignment 18, is operated via main inductors 7, 10, by low frequency currents, e.g. from the mains supply 16, the inductors 27 being tuned to the low frequency used. Speech communication in each direction, is maintained using the two pairs of secondary inductors 8, 11 and 9, 12 respectively. A carrier wave is fed by known means into the circuits 8, 11 and 9, 12, and modulated by the microphones 23, 25 respectively, demodulation taking place at the receivers. The tuning of the low frequency circuits prevents operation of the visual alignment indicator by speech currents. A further embodiment for communication between a fixed station and a movable station includes a series of inductors connected to a rotary searching switch, Fig. 2 (not shown) at the fixed station. The switch ceases rotating when the movable object is brought into fixed alignment with the coils.

An arrangement for disconnecting part of a load when the load current becomes excessive and for subsequently reconnecting the part of the load, comprises resistors 1, 2 across which voltages are produced by the load current, rectifiers 3, 3<SP>1</SP> for rectifying the voltages for application to the base-emitter circuit of a transistor 8 and a relay 9 having its operating coil in the collector circuit of the transistor. When the load currents become excessive, the transistor 8 conducts and causes the relay 9 to changeover its contacts and connect the heaters of thermal switches 16, 17 in series with the resistors. When either or both of the switches close their contacts, a circuit 18 is completed to operate a switching means (not shown) to disconnect the part of the load.

Title: Improvements in the manufacture of cast iron
Inventor: MORROGH HENTON
IPC: C21C1/10
Filed: 1951-02-07
Abstract: In the production of grey copper-containing cast iron, which is hypoeutetic in relation to carbon, the graphite present is rendered wholly or predominantly in the nodular form by introduction into the iron of Mg before, after or simultaneously with Ce.  These elements may be added in the form of an alloy containing them both and this alloy may contain also Ni or Cu. The resulting cast iron may contain Cu 1-7 per cent, Ce 0.001-0.2 per cent and Mg 0.02-0.2 per cent. After the addition of Ce and Mg an inoculant such as ferro-silicon may be added.  The treatment may be applied to cast iron of the following composition: C up to 4.3- 1/3 (Si+P) per cent; Si up to 7.0 per cent, Mn up to 7.0 per cent; P up to 2.0 per cent; S up to 0.25 per cent; Fe the remainder.

Title: Improvements in or relating to apparatus for measuring well depths and well strings

Filed: 1939-01-28
Abstract: 524,392. Measuring well-depths and well-drill &c strings. HAYWARD, J. T. Jan. 28, 1939, No. 3019. [Class 85] Means for measuring the depth of a well, or the length of a string of drill &c: rods depending into the well includes a releasable drive connection through which movements of said string actuate a register, and circuit-closing means actuated when the weight of the string is transferred to a relatively stationary member such as the rotary table, whereby the drive connection is released. In Fig. 3, the travelling block 4 supporting the drill string is connected by wire &c. 28 to a drum 31, a spring within the drum tensioning the wire ; the drum acts through clutch 38, controlled by solenoid 45, to actuate a register 41 including a counter 61 actuated by movement in both directions to give the length of the drill string, and a counter 60. actuated only on downward movement of the string to give the well depth, counter 60 being inactive while its reading is greater than that of counter 61. The rotary table 7 contains a switch 52 connected to slip ring 53 contacting with brush 56. When the weight of the drill string 13 is transferred to the table through wedge slips 27, as for adding or removing rods &c. to or from the string, the slips 27 close the switch and the solenoid 45 is energised to disconnect the clutch 38. For measuring casing strings, the switch 52 is incorporated in a spider supported on the table 7. In another form, the switch is arranged below the table 7 which is supported by strings, the switch being closed by depression of the table. In a further form, disconnection of the counter is effected by the usual weightindicator mechanism. In Fig. 9, the drum 31 is replaced by a pulley 29 over which the measuring line 28 passes, said line carrying a weight 66 ; a self synchronous system, such as a "Selsyn" system, comprising motors 64, 65, connects the pulley 29 to the shaft 33. In this form, the clutch 38 may be omitted, the switch then controlling the circuit of the motors.

Title: Improvements in mineral lubricating oil compositions
Filed: 1948-02-05
Abstract: A composition suitable for use as a cutting oil or extreme pressure lubricant comprises a major proportion of mineral lubricating oil and a minor proportion of a solution of sulphur in a solvent comprising a halogen-bearing alkylated aromatic compound.  Examples of suitable halogen-bearing alkylated aromatic compounds are those derived from alkylated naphthalenes and alkylated benzenes.  Particularly suitable alkylated naphthalenes are those wherein the alkyl group is methyl, ethyl, amyl, decyl or octadecyl and those derived from a coal tar oil cut boiling between 400 DEG  and 600 DEG  F. which is largely a mixture of alkylated naphthalenes.  Alkylated benzenes mentioned are dialkyl benzenes and similar high-boiling alkylated benzenes containing one or more alkyl groups.  The composition may be prepared by mixing the lubricating oil and the solvent, heating the mixture to about 250 DEG  F. and stirring in the sulphur.  A small amount of oleic acid may be added if desired.  In an example, the composition consists of 80 parts by weight of light petroleum lubricating oil, 20 parts of 2-methyl-4-chloro-naphthalene and 1 part of sulphur.  U.S.A. Specification 2,188,255 is referred to.  The Specification as open to inspection under Sect. 91 contains additional examples corresponding to examples 1-4 of U.S.A.
