Abstract: 696,414. Open-hearth furnaces. SALEM ENGINEERING CO., Ltd., and JONES, H. Oct. 16, 1950 [July 15, 1949], No. 18658/49. Class 51(ii) In a reversible open-hearth furnace having at each end thereof, a slag pocket which extends vertically below the furnace hearth and opens to the interior of the furnace beyond the adjacent bridge plate of the furnace, each end wall of the furnace at the throat of the slag pocket and between positions located respectively above and below the bridge plate is inclined upwardly and inwardly towards the hearth, and burners are accommodated in the said inclined wall portions above the level of the bridge plates in such a manner that they do not project into and obstruct the flow of gases through the throats to any material extent. In the reversible open hearth furnace shown adjacent each bridge plate 2 is a slag pocket 3 the upper end of which communicates with the hearth 1 through a throat 4 whilst the lower end is connected to a regenerator via an opening 5. The end wall 6 of each slag pocket has an end portion 7 which is inclined towards the throat 4 at an angle of 45 degrees. The burners (not shown), which do not project from the wall surface, are built into each inclined wall 7 in the vicinity of the roof structure 9 and are arranged in such a position that their longitudinal centre lines 11 pass over the adjacent bridge plate 2 and intersect the workreceiving surface of the hearth midway between the two bridge plates. The angle of inclination of wall 7 may very between 45 degrees and 60 degrees also the wall 7 may be constructed as part of the roof structure 9. Alternatively the lower end of wall 7 may be a part of end wall 6 and its upper end may be part of the roof 9. In the latter case the roof structure end may be inclined at a greater angle than the other and lower end and may extend from the roof to the region of the burners.

Title: Improvements in or relating to impulse transmitters for telemetering systems
Inventor: SMITH STANLEY COLIN
IPC: H04M15/10
Filed: 1953-05-06
Abstract: 760,909. Voltage and current measurements. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Feb. 22, 1954 [May 6, 1953], No. 18882/55. Divided out of 760,802. Class 37. [Also in Group XL (c)] A circuit for converting a variable direct voltage into a characteristic rate of electrical impulse transmission comprises a capacitance chaiged to an extent corresponding to the instantaneous voltage value, a gas discharge device which becomes conductive when the charge attains a predetermined value, a relay responsive to the conductive conditions to initiate a transmission impulse and complete a discharge circuit for the capacitance and responsive to the extinction of the discharge device to terminate such impulse and disconnect the dis. charge circuit from the capacitance and further capacitance means for maintaining the discharge device conductive for a predetermined period succeeding the initiation of the impulse. The voltage to be telemetered (e.g. the rectified output of a current transformer in an alternator circuit) is connected over terminals 10, 11 to charge capacitance C<SP>1</SP> over resistance R<SP>1</SP> and apply an increasingly positive voltage to the control grid of triode VT<SP>1</SP>, whose cathode is positively biased by potentiometer R<SP>2</SP>, R<SP>3</SP>, R<SP>4</SP> across the H.T. supply 12, 13. Anode current increases until the voltage drop across load resistance R<SP>5</SP> ignites discharge tube VN in shunt therewith to pass an increased anode current sufficient to operate relay F/2. Contacts F<SP>1</SP> close to discharge capacitance C<SP>1</SP> over resistances R<SP>4</SP>, R<SP>6</SP>, contacts F<SP>2</SP> change over to transmit a signalling pulse to a remote station, and F relay - is de-energized, after a time delay im. 2 posed by capacitance C<SP>2</SP> shunting the anode of triode VT<SP>1</SP> to earth, so that the circuit is restored to normal after pulse transmission. Capacitor C<SP>3</SP> shunting R<SP>4</SP> is proportioned so as to neutra. lize the charge on C<SP>1</SP> when contacts F<SP>1</SP> close, and thus to accelerate discharge, while capacitor C<SP>4</SP> inter-connecting the anode and grid of VT<SP>1</SP> reduces by Miller effect the required value of C<SP>1</SP> for the necessary circuit time constant. The interval between the transmitted pulses is inversely proportional to the input voltage and the frequency of the emitted pulse train is directly proportional thereto. Transmission to the receiving station (of the kind described in Specification 760,802) may be by line or radio link.

Title: Method and machine for the manufacture of tanks from fibre reinforced plastic material
IPC: F17C1/16
Filed: 1967-04-28
Abstract: 1,150,131. Making tanks. R.S.F. RESIN FIBER'S SYSTEM S.r.1. 28 April, 1967 [29 April, 1966], No. 19651/67. Heading B8G. [Also in Division B5] A method of making a hollow tank from rovings 3 of plastics soaked fibrous material, e.g. glass, comprises winding the roving about a rotating core 1 by traversing the roving to lay it helically on the cylindrical part of the core, and, at the ends of the core, discontinuing the traverse and while the rotation of the core continues, effecting radial movement of the roving to lay it over the ends of the core. The rovings are laid over the ends of the cores in a starshaped formation, e.g. a five pointed star as shown in Fig. 7, and each successive star is circumferentially displaced from the preceeding star until the core is covered. In Fig. 1 the core 1 on a spindle 2 is rotated by an electric motor 12, gear-box 13 and gearing 14, 15 which also drives a control mechanism comprising a stretchable belt 50 having an abutment 34 which acts on two switches 32, 33. The roving guide 4 is mounted on the piston rod 3 of a fluid operated cylinder 8 situated on a carriage 5 reciprocated by a chain drive 19 driven by a chain 26 from a sprocket 25 driven from the motor 12 by way of a coupling 17. In use, in relation to Fig. 1, the roving guide 4 is withdrawn by the piston rod 3 and, with the core 1 rotating, is traversed to the left. At the end of the core the carriage operates a switch 131 that actuates the coupling 17 to disconnect the traverse to the carriage and, with the core still rotating the abutment 34 operates the switch 32 to cause the cylinder 8 to move the roving radially of the core to lay it over the end of the core (Fig. 4, not shown). The switch 33 is then operated by the abutment 34 to cause the roving guide to withdraw radially so that the roving is then, due to the continued rotation of the core, on the other side of the core, the switch 33 also actuates the coupling 17 so that traverse of the carriage is restarted and the carriage 5 moves to the right to lay the roving on the cylindrical part of the core until the other end is reached whereupon the procedure is repeated. The controls are operable to form various configurations of rovings and embodiments are described wherein the core is either removed from the tank or left to form a lining.
