Patent GB-800836-A (GB)
Title: Process for the manufacture of lining for metallurgical furnaces
IPC: C04B35/057
Filed: 1956-06-20
Abstract: The lining for a crucible of an induction furnace is prepared by ramming dry lime between a core and the furnace coil, and bringing it to a temperature of approximately 2000 DEG  C.  This may be effected by heating a graphite core, which need have no direct contact with the crucible, until a thoroughly sintered layer of about 5-20 mm. thickness has been formed on the lining.  A neutral gas such as nitrogen or argon may be introduced between the graphite core and the crucible wall.  A temperature range of 1800-2000 DEG  C., with a calcining time of 1/2 -2 hours, have proved to be sufficient.  The resultant lining is said to be resistant to pressure and to the action of water vapour or CO2.

Title: A method of, and apparatus for, the winding of a web of material
IPC: D06B17/04
Filed: 1958-06-17
Abstract: 834,388. Feeding webs. BENTELERWERKE A.G. June 17, 1958 [June 18, 1957], No. 19322/53. Class 100(1) A method of winding webs of material wherein rollers on which a web is wound are movable to and from a winding position, an unwinding position and an intermediate position, and wherein a web is first wound in a single layer on to a roller in the winding position, this loaded roller is then moved to the unwinding position, while an unwound roller is moved from the intermediate position to the winding position, whereafter the web is wound in a double layer on the unwound roller, one layer being withdrawn from the wound roller in the unwinding position and the other layer being drawn from the length of web fed in for winding. As shown, a web 8, to be subjected to wet treatment, such as dyeing, bleaching &c., is drawn into an enclosure 9. The web is first wound on a roller comprising parts 1 and 2 having a slot 13, at their abutting faces, for receiving the end of the web. The roller parts 1 and 2 are carried by top and bottom chains 6 which move along triangular paths. A roll is wound on the roller by means of a roller 14 engaging the roller peripherally or by driving the roller directly from outside the enclosure. When the roll is complete, the chains 6 move the roll along guides 16 to an unwinding position, while a further roller comprising top and bottom parts 1, 2 reaches the previous winding position. A double layered roll is then wound on this roller, one layer being drawn from the previously wound roll and one layer from outside the enclosure 9. The roller parts are locked together by a latch 24 (Fig. 5 not shown) during winding, the latch being released to permit separation of the parts after unwinding. In a modification, (Fig. 6, not shown) the rollers are formed by rods 32 mounted in segments. The chain drive may be controlled by a switch 23 operated by a roller 20 engaging the web, such that the roller 20 is lifted upon tautening of the web upon completion of the unwinding of a roll in unwinding position. Specification 736,763 is referred to.

Title: Improvements in wireless receiving sets
IPC: H04W88/02

Abstract: 381,574. Wireless receiving systems. DEAN, C. L. P., 73, Drayton Gardens, West Drayton, Middlesex, BEGBIE, C. W. H., 5, Easter Terrace, Brighton, and CLENCH, E. C. S., 4, Queen's Court, Queen's Road, Bayswater, London. July 4, 1931, No. 19348. [Class 40 (v).] The reception of a signal by a detector valve energizes an electromagnet which closes the circuit of a buzzer or other calling device, whereupon the operator switches in manually a low-frequency amplifier and a 'telephone receiver. As shown in Fig. 1, a loop aerial L1 .is associated with a back-coupled detector valve V1, which includes quenching circuits L4 C4, L5 C5 in its grid and plate circuits so that it operates on the super-regenerative principle. The detector plate circuit also includes a transformer coupling to an audiofrequency amplifier V2 and the contacts 1, 2 of a plug A. The contact 3 on the plug completes the filament circuit of the valve V1. Contacts 1, 2, 3 are wired to contacts 1<1>, 21, 31 of a buzzer, Fig. 2. On receipt of a signal, the current in a coil C changes and contacts E close, making a circuit from the HT positive through contact 2<1>, buzzer contact and coil D, and contact 3<1> to HT negative. On hearing the call, the operator plugs in his telephone plug B, so closing the filament circuit of the valve V2. The buzzer may be put out of action by a separate hand switch, or by contacts operated by the plug B, or by withdrawing the plug A. In the latter case, the plug is arranged to maintain the detector filament and plate circuits energized. If the valve V2 should fail, the plug B may be inserted in place of the plug A.

Title: Improvements in or relating to aerial systems
Inventor: KRAVIS ALEC

Abstract: 884,889. Aerials. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Nov. 25, 1959 [June 8, 1959], No. 19515/59. Class 40(7). An aerial comprises at least one set of dipoles, the dipoles of each set being arranged parallel to one another and perpendicular to a balanced feeder along which the dipoles are spaced. The spacing and the length of the dipoles increases logarithmically from the end of the feeder to which is connected the associated radio equipment. One embodiment, Fig. 1, comprises dipoles D1, D1<SP>1</SP>-D7, D7<SP>1</SP> connected to feeder F as shown. The spacing between adjacent dipoles is between one half and one fifth, preferably one quarter, of the electrical length of the shorter of the dipoles. This aerial is directional in the direction A. The dipoles may be loaded, and the feeder terminated by a resistor R. This aerial may be modified to give circularly polarized radiation by connecting a second set of dipoles to the feeder, perpendicular to, and interspersed with, those of the first set, Fig. 2 (not shown). An aerial system for use with both vertically and horizontally polarized waves comprises two component aerials, each consisting of a feeder and a set of dipoles as described with reference to Fig. 1. The component aerials are placed together such that their feeders are substantially parallel and the dipoles of the two sets interleaved and perpendicular to each other. A further embodiment, Fig. 4 (not shown), provides an aerial having the feeder mounted vertically, and similar to the aerial of Fig. 1 except that each dipole is rotated through 90 degrees with respect to those on either side so that the spacing between adjacent parallel dipoles is approximately double that of adjacent dipoles in Fig. 1. This aerial radiates horizontally polarized waves uniformly in all directions. All the above aerials have wide band-width, and all except the last may be made more directional by using a parabolic or other reflector, or stacked to give additional gain.

Title: New or improved method of and means for starting diesel engines
IPC: F02N19/04
Filed: 1958-06-18
Abstract: 843,247. Starting diesel engines. DAIMLERBENZ A. G. June 18, 1958 [July 5, 1957], No. 19534/58. Classes 7(2) and 7(5). In a method of starting a four-stroke cycle diesel engine especially with direct injection of fuel into a piston trough, the exhaust passage 6 is closed by a valve 8 disposed as closely as possible beyond the cylinder head whereby the air charge in the cylinder is compressed against the closed valve during the exhaust stroke, the air partly remaining in the cylinder under high pressure and partly flowing back into the induction port during the overlapping opening of the induction and exhaust valves 3, 4, so that during the next intake the cylinder becomes charged with air of higher temperature instead of with cold air and there is a rapid building up of the compression end temperature. The valve in the exhaust passage may be one which is normally used for exhaust braking. In engines having a very small valve overlap a cross connection between the closed exhaust passage and the induction passage or between the induction and exhaust ports in the cylinder head is opened on starting by a cam and valve. On the cam shaft a starting cam may be provided and the cam shaft may be displaceable so that the starting cam can be brought into operative position. The starting cam may be designed to effect a reduction of the maximum compression pressure. Upon bringing the fuel injection into operation the cam shaft may be automatically shifted. A portion of the induction pipe and/or a portion of the exhaust pipe may be heated by a flame unit or electrically.
