Title: An improvement in or relating to mills for rolling metal
Inventor: WILSON ALEXANDER IAN
IPC: B21B31/26
Filed: 1963-02-06
Abstract: 1,061,082. Rolling. HILLE ENGINEERING CO. Ltd. Feb. 5, 1964 [Feb. 6, 1963], No. 4842/63. Heading B3M. In a rolling mill with two co-operating rolls the chocks of one roll are pivotally connected to the adjacent chocks of the other roll by pivot pins whose axes extend transversely of the rolls. Each upper chock 14 of a roll 10, Fig. 2, has recesses 30 and 32 in which are housed extensions 34 and 36 of a lower chock 18, pivot pins 38 pivotally connecting the chocks and supporting the chocks on the uprights 64, 66 of a housing 3. The pivot pins have coaxial portions 40, 42 and 44 and an eccentric portion 54 so that rotation of the pins raises or lowers the lower chock 18. The eccentric portions 54 are mounted in horizontally slidable blocks 58 which slide in the chock 18 to prevent the horizontal component of motion of the eccentric from moving the lower roll axially. Similar blocks 52 supporting the portions 44 of the pins allow axial adjustment of the rolls. Rotation of the pivot pins (Fig. 1, not shown) is by means of levers (68) which are rotated by movement of a trunnioned nut (70) on a driven screw (72). The rotation of the levers may alternatively be by means of worms at each end of the rolls co-operating with segmental pinions, the roll adjustments at each end of the rolls being independent in this instant. The pivot pins (Fig. 4, not shown) may alternatively be provided with coaxial portions (90) and (92) and eccentric portions (98) and (94), rotation of the pins effecting equal and opposite vertical movement of the chocks (80) and (82) so that the pass line remains fixed. Horizontal movements of the portions (92), (94) and (90) are accommodated by sliding blocks (106), (96) and (104). In a further embodiment pivot pins of the same configuration are used, each portion (98) being mounted in a sliding block while the portions (92) and (90) are accommodated simply in bores in the chock (80). The pivot pins, instead of being in one piece, may have eccentric sleeves mounted on a pin. The sliding blocks and the bores in which they slide may be treated with an anti-friction material, or may be provided with reservoirs of hydraulic fluid, or needle or roller bearings. The invention may be embodied in a 4 high mill, the chocks of the working rolls being mounted in supporting roll chocks which are pivotally supported.

Title: Impulse coincidence circuit
IPC: H03K19/12
Filed: 1953-02-23
Abstract: 729,257. Coincidence circuits. STANDARD TELEPHONES & CABLES, Ltd. Feb. 23, 1953 [Feb. 21, 1952], No. 4982/53. Class 40 (6). A coincidence circuit comprises a capacitor which is charged by negative and by positive pulses so that only when a negative and positive pulse are present simultaneously does the charge acquired by the capacitor reach a value sufficiently large to cause an output pulse to be produced. Fig. 1 shows a coincidence circuit in which when-switch 11 alone is operated a negative pulse is applied at terminal 1 to charge capacitor 3 via rectifier 8 and when switch 12 alone is operated a positive pulse is applied at terminal 6 to charge capacitor 3 via rectifier 8. When both switches 11 and 12 are operated simultaneously the charge acquired by capacitor 3 causes rectifier 4 to conduct to produce an output pulse at terminal 2. In a modification shown in Fig. 3, when capacitor 3 is charged by positive and negative pulses applied simultaneously at terminals 6 and 1 respectively the potential at point 5 rises sufficiently to fire coldcathode gas discharge tube 21.

Title: Method and means for quietening the hydraulic operation of turbines
IPC: F03B11/00
Filed: 1958-02-18
Abstract: 850,112. Hydraulic turbines. ETABLISSEMENTS NEYRPIC, ATELIERS NEYRETBEYLIER & PICCARD-PICTET. Feb. 18, 1958 [Feb. 18, 1957], No. 5304/58. Class 110 (3). [Also in Group XXVIII] The noise of operation of an hydraulic turbine having a chamber formed between the turbine casing and the upstream side of the wheel which is subject to a pressure above atmospheric by the flow of water through the turbine, is quietened by introducing into the chamber an emulsion of air and water in sufficient quantity to damp the pressure pulses created by the operating turbine and feeding the emulsion from the chamber into the central portion of the water flow downstream of the rotor. The chamber formed between the hub disc and casing of an inward radial flow hydraulic turbine is supplied with an emulsion of air and water by an injector, Fig. 1, which comprises a hollow cylindrical body 10, the upper end of which is provided with a ball valve 11 and the lower end with a convergent nozzle 12 discharging into a mixing pipe 13 connected to the turbine casing 21. An arcuate pipe 15 fed with liquid from the turbine inlet has its outlet end coaxial with the axis of the body 10, formed as a jet nozzle 17. Radial partitions 18 and a central tube 19 are arranged inside the nozzle 17. When water flows through the pipe 15 it passes from the nozzle 17 in the form of a plurality of jets 22, Fig. 2, which are separated by gaps 23, 24 to which air is supplied through the valve 11. An annular gap 25 also forms an air passage. This air mixes with the water in pipe 13 to form an emulsion which is then fed to the turbine. The emulsion is led from the chamber through the nose of the rotor hub to the suction pipe. The central tube 19 may, if desired, be dispensed with.

Title: The manufacture and application of new quaternary ammonium compounds
Filed: 1934-02-20
Abstract: Polyethylenepolyamine mixtures, containing substantial proportions of compounds of the formul  H2N(C2H4NH)nC2H4NH2 and (C2H4NH)n in which n is greater than 2, are converted into quaternary ammonium compounds by treatment with alkylating or aralkylating agents.  In an example, a polyethylenepolyamine mixture is freed by distillation from the fraction boiling up to 220 DEG  C. under 10 mm. pressure, and the residue is treated with dimethyl sulphate in an aqueous medium kept alkaline with sodium carbonate.  Arylsulphonic acid alkyl esters may also be used as alkylating agents; benzyl chloride is specified as an aralkylating agent.  Alkylation may be effected in two stages; in the first stage, tertiary amines are formed by treating the starting material with an alcohol and hydrochloric acid, while in the second stage quaternary ammonium compounds are formed by further alkylation. The products are useful for after-treating cellulosic materials dyed with substantive dyes, to improve the fastness of the dyeings. Specifications 423,864 and 423,933 are referred to.

Abstract: 634,724. Cathode-ray oscillographs. PHILIPS LAMPS, Ltd. Feb. 28, 1947, No. 5851. Convention date, March 5, 1946. [Class 37] In a known system, the value of a direct voltage is shown on a cathode-ray tube by the distance between two lines 15, 16, symmetrically disposed about a zero line, with the aid of an electronic commutator 1 which operates at 800 c.p.s. and renders an input 2, to which the voltage is applied, and an input 3, which is short-circuited, operative on the tube in turn. This system has the defect that when the voltage changes, only one of the lines shifts immediately, the other taking a time dependent on the R.C. couplings in the circuit 1 to take up its new position. In the present invention, this defect is overcome by applying to the input 3, which in the prior system was short-circuited, a voltage obtained by rectification from the output of the commutator in the opposite sense to the voltage to be measured.

Abstract: 1467026 Number senders; oscillators IWASAKI TSUSHINKI KK 8 Feb 1974 [10 Feb 1973 21 Sept 1973] 05862/74 Headings H4K and H3T In a two-tone oscillator which comprises a pair of LC circuits and respective sets of transistors for selectively connecting different taps on the inductors into the oscillator circuit, one transistor from each set is selected upon actuation of a single key controlled contact by means of a diode translation matrix, while simultaneously a D.C. flow through the inductors is terminated. In the figure, the two LC circuits comprise transformer coils 43, 44, 45 and 40, 41, 42 with capacitors 52 and 51, and switching transistors 59 and 58. In operation, closure of a contact, e.g. 11, in keyset 10, causes (via matrix diode 28) transistor 57 to turn-on and transistor 79 to turn-off. The latter opens a telephone speech circuit incorporating microphone T. Matrix diodes 21, 25 enable one transistor in each set 59, 58 thereby determining the frequencies of the oscillator. Release of the key terminates the oscillation. In order to speed up the onset of oscillation it is stated that current should be flowing through the coils in the two LC circuits prior to switch-on. As shown the current path is provided via transistors 70, 71, transistors 59-4, 58-3 and 63, 64. Consequently when a key is depressed, transistors 59-4, 58-3 are cut-off so as to terminate D.C. flow through the coils 43, 40 whilst one each of transistors 59 and 58 is selected to provide two-tone oscillation In Fig. 4 (not shown), transistors 70, 71 are replaced by a single transistor and a pair of diodes while in Fig. 5 (not shown) they are replaced by a pair of diodes. The number generated may be displayed to the user.
