Title: Driving mechanism
IPC: D04B15/94
Filed: 1972-11-03
Abstract: 1385120 Changing speed of induction motors ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 3 Nov 1972 [8 Nov 1971] 50678/72 Heading H2J  The rotating parts of a circular knitting machine are braked for a controllable time when changing the speed of the electric driving motor so that wastage is reduced. A three phase, pole charging motor 12 is connected to the supply through a contactor controlled by electromagnet 7 which is energized through relay 5. Additional contacts g, h on the contactor connect a capacitor 11 across a supply so that it is charged up. A further capacitor 2 is connected to the supply through a changeover switch 1 which is operated when a speed change is needed. Operation of switch 1 causes capacitor 2 to discharge through relay 5 which de-energizes contactor electromagnet 7 to close the contacts e,f and connect brake operating coil 9 across capacitor 11. Relay 5 will remain operated until capacitor 2 is discharged and thus the size of this capacitor determines the time of operation of the brake.

Title: Method and apparatus for purifying steel
IPC: C21C7/10
Filed: 1964-12-15
Abstract: Steel is produced with a carbon content in excess of that required in the final product and is then transferred to a refractory-lined ladle of non-magnetic material which is placed in a vacuum vessel.  The latter is then rapidly evacuated while the bath is stirred magnetically to expose all the metal to vacuum and to cause a continuous flow of metal against the refractory material whereby gas bubbles are nucleated.  This process may be aided by introducing nucleating particles such as alumina, crushed refractory, nickel pellets or cast iron shot to the bath.  When gas evolution has ceased aluminium and/or silicon may be added whilst stirring is continued. In the particular form of apparatus described Fig. 1 (not shown) the ladle (22) is mounted on a suitable stand (26) inside the vacuum tank (11) having a cover (15), and is partially surrounded by stirrer coils (28, 29, 30, 31) which are suitably connected to a source of power to produce the desired circulation of the bath.  The ladle is surmounted by a splash cover and heat reflector (35, 37) which has openings for the inflow of molten metal, for the addition of the necessary refining and alloying agents and for observation of the bath. Accurate location of the ladle and its cover is obtained by providing them with sleeves which slide on to the extended posts (27) of the ladle supporting structure.

Abstract: 1376808 Dictation machines INTERNATIONAL BUSINESS MACHINES CORP 21 Nov 1972 [22 Dec 1971] 53669/72 Heading G5R In a dictation machine of the type described in Specifications 1,305,362 and 1,337,163, in which dictated sentences are recorded in separate record tracks and are identified by sentence and paragraph numbers which are stored and subsequently used to determine the order in which the sentences are reproduced, the store has provision for altering the sentence and paragraph numbers of any sentence. This enables paragraphs to be split or combined. Paragraph splitting.-A split button 1 is pressed, followed by a sentence button 2 which determines which sentence of the paragraph being edited is to start the new paragraph. The memory 6 is then scanned by a compare register 7 and the sentences of the new paragraphs are given appropriate new sentence and paragraph numbers. All sentences in paragraphs following the new one are also given new paragraph numbers (plus one). The head 11 is finally positioned at an empty track following the reduced paragraph. Paragraph combination.-A combine button (15), Fig. 2 (not shown), and first and second paragraph buttons (16a, 16b) are pressed sequentially, and determine which first paragraph is to be added to the end of which second paragraph. An alarm is given if the combined paragraph has more than a maximum number of sentences. Sentences of the first-selected paragraph are given appropriate new sentence and paragraph numbers, and all sentences in paragraphs following the first-selected one are given new paragraph numbers (less one). The head 11 is finally positioned at the start of the combined paragraph. Recording instructions.-Instructions to the typist may also be recorded on a group of tracks reserved therefor. On pressing a button (40), Fig. 3 (not shown), the first empty track of this group is selected, and on pressing an End-of-Sentence button (41) the head 11 automatically returns to the start of the sentence which was previously being dictated. Sentence extension.-If it is desired to extend a sentence and the next track is full, an alarm is given and an Expand button must be pressed.

Abstract: 1,218,556. Holography. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 21, 1968 [Oct.26, 1967; Nov.30, 1967], Nos.48842/67 and 54661/67. Heading G2J. A holographic three-dimensional reconstruction of a scene comprises producing a plurality of representations of the scene, e. g. on a cine film, at a corresponding plurality of viewing angles relative to the scene and then making holograms from these representations on a common photosensitive sheet by directing a non-diffused object beam from each representation on to the sheet at an angle corresponding to the viewing angle of the representation and a reference beam on to the sheet at a constant angle for all holograms, the holograms being reconstructed using a reference beam directed at said constant angle on to the sheet. In one embodiment a camera 10 is rotated at a constant distance about a point P of a scene taking single frame pictures over a prescribed arc. The film is developed and placed in a laser beam 16. By suitable pinhole and lens arrangements this gives a parallel object beam which is directed on to a photographic plate 25. A reference beam 17 from the same laser source is directed on to plate 25 via a mirror 29. Both mirror and plate are rotated together, the mirror at half the angular velocity of the plate so that after each exposure the plate is positioned relative to the film at the corresponding viewing angle for that exposure and the reference beam is incident upon the plate at a constant angle. Preferably the construction reference beam is divergent. In reconstruction.a less divergent (preferably parallel) reference beam, (e.g. from a mercury lamp, may be used which will enable the reconstruction to be seen without the aid of lenses. In order for the reconstructed rays to meet at a conjugate reconstriction point the distance of the camera from the centre of rotation P must be large compared to the distance of individual points in the scene from P. In an alternative embodiment the camera is not moved around the points but is passed or tilted to give the various viewing angles.
