Title: Variable transformers
IPC: H01F29/00
Filed: 1975-10-31
Abstract: 1528130 Transformers TRANSFORMATOREN UNION AG 31 Oct 1975 [2 Nov 1974] 45400/75 Heading HIT In a variable transformer having a secondary winding comprising a main winding and a tapped winding, protection against voltage surges is effected by a capacitative control winding wound adjacent a secondary winding and comprising two equal parts joined by an external connection. Fig. 7 shows a development of a helical winding 1 alongside which a control winding 2 is wound. For every five turns of the main winding there are two control winding paths, each of which extends over 2¢ turns, with inner ends 4 being insulated from each other and outer ends being joined by a conductor 3. Figs. 1-6 (not shown) indicate diagramatically the association of control windings with various arrangements of main winding layers. Fig. 8 (not shown) discloses control windings applied to a tapped winding. Figs. 9 and 10 (not shown) show arrangements where the control winding parts each comprise a single turn, and the external connection joins a turn at the high voltage end with one at the low voltage end.

Title: Centrifugal separator
IPC: B04B1/18
Filed: 1971-09-30
Abstract: 1308266 Centrifugal separators WESTFALIA SEPARATOR AG 30 Sept 1971 [2 Oct 1970] 45583/71 Heading B2P In a self-cleaning centrifuge comprising a centrifuging drum having discharge orifices 4 which are opened or closed by a piston valve 3, a closing chamber, into which control liquid is admitted to control the movement of the piston valve, is divided into two or more compartments 6, 7 which lie radially behind one another and means 10, 12 and 11, 13 are provided for selectively emptying the compartments. The compartments 6, 7 are sealed from each other by the piston valve 3 sealingly engaging the drum part 5 at 9. Discharge channels 10, 11 at the radially outer ends of the compartments are controlled by valves 12, 13 which are so designed that their control body on the one side, in the opening sense, is subjected to the pressure of the drum contents, and on the other side, in the closing sense is subjected to the pressure of control liquid in a chamber of the valve, the chamber having a bore leading outwards through which control liquid can continuously emerge. The control liquid is continuously supplied to the chambers of the valve separately through line 16 and channel 23 and line 17 and channel 24. Valves 14, 15 in the lines 16, 17 are opened or closed by a control device 18 in accordance with a set programme. As long as the supply takes place, the valve body is maintained in the closed position by the greater closing pressure, so that no liquid emerges from the compartments 6, 7 through the channels 10, 11 and valves 12, 13. When control liquid supply to the valve 12 or 13, or to both valves, is optionally interrupted, the relevant valve chamber discharges through the bore leading outwards. After removal of the pressure in the chamber, the valve body is shifted into the open position, under the pressure of the drum contents, and the liquid is let out of the compartment 7 or 6 or out of the two compartments, thereby effecting partial or complete emptying of the drum. In a modification, Fig. 2, (not shown), the valves 12, 13 are closed in the liquid-free state and are opened by the supply of control liquid. The mode of operation is thus the reverse of that described with reference to Fig. 1. In a further modification, Fig. 3 (not shown), the closing chamber is divided into three compartments and calibrated discharge passages for the control liquid lead outwards of the compartments instead of valve-controlled channels as in Fig. 1.

Title: Method of isolating transferrines from biological materials
IPC: C07K14/435
Filed: 1974-10-22
Abstract: 1463327 Isolating conalbumin &c. from biological materials OFFICINA TEREPEUTICA ITALIANA OTI LABORATORIO BIOLOGICO SpA 22 Oct 1974 [31 Oct 1973] 45750/74 Heading C3H A method of isolating a transferrine, particularly conalbumin, from biological material containing recoverable transferrine, involves passing the biological material in fluid condition at a pH between 3 and 6 through a solid carrier containing chelating groups coordinated to metal ions (iron, copper &c.) in the presence of a buffer solution at a pH between 3 and 6 which is free of chelating properties, and then eluting the resulting transferrine-metal complex from the solid carrier and recovering pure transferrine in a conventional fashion. An acetate buffer solution of molarity between 0À01 and 0À2 M is used in adsorbing the transferrine on the carrier. For the elution of the transferrine complex produced, either a buffer solution having a pH between 6 and 11, or a buffer solution of pH between 3 and 6 containing chelating groups (sodium citrate) at a concentration of 10<SP>-3</SP> M or higher, is suitable. The biological material is first deionized by treatment with a mixture of anionic and cationic resins. Compounds having chelating properties of M.W. lower than 10,000 i.e. lower than that of transferrine, may be removed by dialysis. The examples are directed to the isolation of conalbumin from egg white using a ferric-carboxymethyl cellulose carrier.

Abstract: 1483509 Electrophonic musical instruments NORLIN MUSIC Inc 23 Oct 1974 [23 Oct 1973 45783/74 Heading G5J An electrophonic musical instrument fills in notes in the octave immediately below the melody note which fill-in notes are octavely related to an accompaniment chord. The keys of the solo manual are scanned by a selection matrix 48 under the control of note code and octave code generators 14, 24 to produce pulses on line 56 indicating by their time slot the highest note played on the solo manual. The keys of the accompaniment manual are grouped in octavely related sets to provide on line 62 pulses whose time slot represents the accompaniment chord regardless of octave. Window logic 58 holds gate 64 open for twelve clock pulses so that line 66 carries pulses octavely related to the accompaniment chord in the octave immediately below the top melody note. These notes are decoded and held by latch unit 44 and used to control a note selector 74. Twelve tone signals at least one octave above the highest required octave are produced by generator 76 and the appropriate ones are selected and subjected to the appropriate binary frequency division by selector 74 under control of latch unit 44. The notes corresponding to different notes of the accompaniment chord may be given different voices by unit 86. In a modification, Fig. 8 (not shown), window logic 58 excludes notes close to the top solo note to avoid dissonance. The circuit of a typical keyer 82 is described Fig. 7 (not shown).
