Abstract: 816,977. Refining iron. HUTTENWERKE OBERHAUSEN A. G. Aug. 30, 1957 [Aug. 30, 1956], No. 27393/57. Class 72 [Also in Group XII] A process for refining iron in a rotary drum furnace which rotates about a substantially horizontal axis in which, for the purpose of maintaining the CO content of the waste gases at a. desired substantially constant value, the depth of immersion of the main blast nozzle is continuously adjusted, manually or automatically, so as to compensate for changes in the level of the surface of the bath which occur during each revolution of the drum. As shown, the depth of immersion of the nozzle 1 may be kept constant by the attachment to the nozzle of two contacts 5 and 6 which by contact with the metal or slag respectively set motor 18 into motion in forward or reverse direction of rotation to advance or withdraw nozzle 1 by means of rack 20 and pinion 19. An alternative embodiment, Fig. 3 (not shown), employs photo-electric cells within the oxygen lance situated behind orifices located near the slag, metal interface and measuring the brightness of metal and slag respectively thus maintaining a constant depth of immersion which results in a constant CO content in the waste gas. The depth of immersion of the nozzle may alternatively be controlled by adjustment in response to changes in the composition of the waste gases, the CO content of which may be kept constant (near 2 per cent) until the end of the process when it may be increased to 40 per cent.

Title: An outgoing trunk signalling and supervision arrangement
IPC: H04Q3/00
Filed: 1969-05-30
Abstract: 1,216,627. Automatic exchange systems. NORTHERN ELECTRIC CO. Ltd. 30 May, 1969 [6 June, 1968], No. 27565/69. Heading H4K. In a system in which, for an outgoing call, a calling subscriber is connected via a line frame, an originating junctor and a trunk frame to an outgoing trunk circuit and in which a sender is connected to the originating junctor during outpulsing, supervision of the connection is vested in the junctor during sending and then in the trunk circuit when sending ceases and the sender has been disconnected. Crossbar switches are used in the line and trunk frames. The system is distinguished from the No. 5 crossbar wherein the sender is connected to the outgoing trunk, and originating junctors are not utilized (Fig. 1, not shown). Details.-It is assumed that the connection is completed up to an outgoing trunk 34 in which a relay ON is operative to an earth on the sleeve lead S. When sufficient digits have been accumulated in a register sender 35, a relay D is brought up in the originating junctor 32 whereby a holding earth for the hold magnets H in the trunk frame and for the relay ON in the trunk is applied to the sleeve. The digits outpulsed from the sender are passed over the Tip and Ring leads to a special signalling path associated with the trunk. When sending ceases, relay D is dropped thus removing earth from the sleeve and allowing low resistance relay EP in the trunk circuit to come-up in series with ON (which is slow to release). A resistive holding earth is thus reapplied to the sleeve via EP until such time as full ground is applied from the calling or called party's supervisory circuit. EP also switches through the talking path at its contacts EP1, EP2.

Title: Tire marking apparatus
Inventor: BUSER ARNOLD SYLVESTER
IPC: B29D30/06
Filed: 1970-06-08
Abstract: 1292167 Testing tyres GOODYEAR TIRE & RUBBER CO 8 June 1970 27569/70 Heading B7C [Also in Divisions B6 and G1] The dynamic unbalance of a tyre mounted on a wheel is measured by a force transducer and the angular position of the peak of the fundamental component of the unbalance signal is marked on the tyre. The periphery of the tyre 48 (Fig. 7), mounted on a wheel rim 50 and rotated on a shaft 51, is sensed by a feeler 52 attached to a force transducer 53. The unbalance signals are fed through filters 57, 59 to remove all but the fundamental component and the peak-to-peak value sensed and stored at 63. The testing and marking sequence is controlled by timers T1, T2 (Fig. 11). When the shaft 51 is rotated limit switches first cancel the last unbalance signal stored in 63 and then store the new peak-to-peak value. If this is excessive, unit 70 energizes a relay HR4 to stop rotation and the tyre is rejected. Otherwise relays HR1, HR2, HR3 energize timer T1 to brake the shaft 51 so that the tyre stops with the unbalance location facing a marker 1 (Fig. 2), and the solenoid windings 44a, 46a of the pneumatic supply controlling the marker are sequentially energized to cause the unbalance location to be marked. The marker 1 (Fig. 2) comprises a branding iron 14 supported on a horizontal shaft in bearings 12 located in arms 10, 11 attached to sleeves 4, 5 slidably mounted on parallel horizontal rods 7, 8. One end of the horizontal shaft carries an arm 20 attached by a spring 22 to an extension 23 of arm 11, which biases the iron 14 to a horizontal attitude against a stop bolt 33. The other end of the horizontal shaft carries a gear 24 meshing with a horizontal rack 26 attached by a rod 27 to pneumatic actuating member 28. Pressurized air is selectively applied to the ends of the actuator via lines 30, 32 as determined by the timing circuit (Fig. 11), causing the marker to dip into a wax container 16 and then move forward against a tyre to mark the location of the tyre unbalance.

Title: Device for utilising the electrostatic attraction produced by the passage of electric current across the surfaces of contact between a semi-conductor and a conductor
IPC: H04R23/00
Filed: 1946-09-14
Abstract: 622,672. Non-contact-making relays; loudspeakers. RAHBEK, K. Sept. 14, 1946, No. 27637. Convention date, Feb. 27. [Class 40 (iv)] In a device of the type disclosed in Specification 144,761, [Class 40 (iv)], in which the electrostatic attraction produced by the passage of electric current across the surfaces of contact between a conductor and a semi-conductor is utilized, the conductor is divided into two mutually insulated parts, which are respectively connected to the two poles of a D.C. source. In this way undesirable effects due to the unidirectional passage of current through the semi-conductor are avoided. As shown in Fig. 1, the cylinder 1 of semiconductor rotates with its surface in contact with a band of conducting material divided into two parts 2, 3 which are insulated from one another as at 4, and are connected to the positive and negative poles respectively of a D.C. source (not shown). As indicated at 7 and 8 the voltage gradients under parts 2 and 3 are opposite in sign, so that each surface unit of the cylinder will be alternately affected by inward and outward voltage gradients. To obtain more frequent changes of potential gradient, each part of the conductor may be divided into segments. A loud-speaker embodiment, Fig. 2 (not shown), is described.

Title: Improvements in sealing containers such as milk bottles
IPC: B67B3/14
Filed: 1936-10-12
Abstract: 476,200. Capsuling milk bottles or like containers. GLUNZ, H. F. Oct. 12, 1936, No. 27688. [Classes 125 (ii) and 125 (iii)] Containers such as milk bottles are sealed with a sheet of cellulose acetate or other cellulose derivative by folding the outer peripheral edge zone of the sheet over the crown of the container, and then compressing the folded portion against the sides of the container while employing heat wherein the outer peripheral edge zone is heated to a constantly increasing temperature during the compressing operation. The cap blanks 13 may be cut from a sheet 10, e.g. of cellulose acetate À001"- À002" thick, by a die punch 11 and die plate 12, the blank being placed by pad 16 on ledge 14 of the disc-holding and disc-conveying ring 15. The pad 16 reciprocates relatively to the punch 11. During the return stroke of the punch the disc - holding ring 15 slides sideways to transfer the cut blank to the capping machine, which comprises jaws 21 pivoted at 22 and operated by cam 23. Six is a convenient number of jaws and they have electrical heating units 25. The ring 15 positions the cap blank beneath a pleating plate 26 underneath the jaws. Upward movement of the container on a table 29 and downward movement of a pad 31, clamps the centre portion of the blank, and continued upward movement of the bottle 28 forces the blank through the pleating plate which being warmed by contact with the lower ends of jaws 21, moulds the edges of the disc over the crown of the container into downturned pleats. Further upward movement of the bottle brings its mouth between the jaws 21 and simultaneously cam 23 is lowered to close the jaws which have first of all a running contact with the folds of the cap and therefore exert an ironing effect to press the folds about the mouth 27 of the container, and then as they close upon an increasing surface of material they become increasingly effective as heating agents until the edges of the cap finally fuse and are moulded to form a continuous one piece cap intimately adhering to the sides of the container. The high temperature employed sterilizes the seal, but since the maximum temperature is not applied until the edges of the cap are in contact with the surface of the bottle, scorching or burning is avoided. The ends of the jaws 23 have adjustable spring pressed points 24 which provide for inequalities in the mouths of the containers. The cap, being transparent, leaves the cover of the milk bottle clearly visible.
