Abstract: 388,363. Making sound-records from several records. BRILLOUIN, J. G. C., 31, Boulevard de Port Royal, Paris. May 19, 1931, No. 14761. Convention date, May 20, 1930. Void [Published under Sect. 91 of the Acts]. Addition to 384,979. [Class 40 (ii).] The method described in the parent Specification for superimposing on a single final record independent separately-recorded component records of any type with provision for adjusting the mean intensity of each component during the re-recording.is modified to comprise two separate operations, first the determination of the intensity of the sounds recorded on the component records, and secondly re-recording on the single record with the intensities thus determined. This is effected by employing an acoustic control apparatus to produce records representing the mean intensities of the component records, and employing these to control automatically the re-recording.

Title: Improvements in or relating to micro-wave frequency-selective couplers
IPC: H01P1/213
Filed: 1964-04-10
Abstract: 1,033,335. Channel combining filters. SIEMENS & HALSKE A.G. April 10, 1964 [April 11, 1963], No. 14856/64. Heading H1W. A microwave channel-combining or-separating filter comprises two hybrid junctions 5, 6 having corresponding pairs of conjugate ports 3, 4 and 3<SP>1</SP>, 4<SP>1</SP> connected through identical filters 7, 8 designed to reflect a first sub-band signal applied to the port 1 of hybrid 5 and to pass a second sub-band signal applied to the port 2<SP>1</SP> of hybrid 6. The distances of the filters 7, 8 from the first hybrid junction 5 differ by one quarter wavelength (# o 4) at the frequency of the first sub-band whereby energy in this sub-band, after reflection by the filters, is fed wholly to the port 2 of hybrid 5. Energy in the second sub-band, after transmission through the filters, is also fed to the port 2. Port 1<SP>1</SP> of hybrid 6 is terminated by a balancing resistor 13. As shown in Fig. 1, both hybrids are of the type comprising three waveguide ports 2, 3, 4 and 2<SP>1</SP>, 3<SP>1</SP>, 41 and single co-axial ports 1, 1<SP>1</SP>. According to the invention, the reflection band of the filters 7, 8 is broadened by incorporating into the input 1 a circuit resonant at a frequency within the first subband, such modification resulting in a reflection characteristic typical of a double-section filter, i.e. an optimally flat or Tschebyscheff characteristic. This may be achieved by providing the inner conductor 20 (Fig. 2, not shown) of the coaxial port with a resonant structure consisting of an inductive probe 18 and a capacitative plate 17. In a modification (Fig. 5, not shown), the hybrid junctions are in the form of 3 db. strip-line couplers 30 having conjugate ports 32, 33 connected through the rejection filters 35, 36. The first sub-band is applied to port 31 and the output derived from port 34. In this circuit broadening of the rejection band is achieved by means of a resonant circuit in the output port 34 consisting of a double section formed by three pairs 48, 46, 47 of screws spaced by half-wavelengths. This type of tuned circuit may be used to replace the structure of Fig. 2 in the circuit of Fig. 1. In this case, however, it is only necessary to use a single section comprising two pairs of screws.

Title: Improvements in and relating to the manufacture of ferrites
IPC: C04B35/26
Filed: 1949-06-02
Abstract: Ferrites suitable for the constitution of magnetic cores are produced by decomposing at a temperature lower than 500 DEG C. mixed oxalate, formate or acetate of iron and the other ferrite forming metals and, after having compressed the powder to the desired shape, heating the product in an oxidizing atmosphere at about 1000 DEG C.  The initial mixed salts may be obtained by precipitation of oxalates from the metal salts solution by adding ammonium oxalate or ammonia and oxalic acids separately.  In a similar manner acetates and formates may be formed.  Examples relate to precipitated oxalates of iron, zinc and nickel, and iron and nickel, decomposed at 320 DEG C. in a current of air, compressed and heated at 1000 DEG C for two hours, and to the crystallization of saturated mixed solutions of the acetates of iron and nickel, subjected to similar heat treatment.  Specifications 594,474, 596,875 and 645,056 are referred to.

Title: Route Advance Control System and Automatic Telephone Exchanges.
IPC: H04Q3/00
Filed: 1967-04-04
Abstract: 1,159,914. Automatic exchange systems. NIPPON TELEGRAM & TELEPHONE PUBLIC CORP., OKI ELECTRIC INDUSTRY CO. Ltd., NIPPON ELECTRIC CO. Ltd., FUJITSU Ltd., and HITACHI Ltd. 4 April, 1967 [14 April, 1966], No. 15437/67. Heading H4K. In a cross-bar exchange having a common translator for providing routing instructions to the markers, the translator includes an alltrunks-busy relay in respect of each route, the contacts of these relays being formed in a chain so as to automatically provide an enquiring marker with instructions regarding the first available route and the marker includes a set of relays which in the event that a path from the calling party to a trunk of the first choice route cannot be set up through the switching network causes the marker to attempt to set up a connection to the other idle trunks if any in this route and thereafter causes this route's all-trunks-busy relay to be operated whereby the translator can then provide the marker with instructions regarding the next available route. This process can be repeated as often as required before busy tone is reverted to the caller. The marker applies to the translator after each unsuccessful attempt to reach an idle trunk and the translator then supplies instructions regarding the same route if this contains any more idle trunks. The trunk which could not be reached on a previous attempt is artificially busied during succeeding attempts to reach an idle trunk of this route or of any other lower priority route. The artificial busying is only removed when the call is finally connected through to a trunk or is abandoned. The relay arrangements in the translator and marker are described with reference to Fig. 3 (not shown). The system is contrasted with the No. 5 Cross-bar System (U.S.A. 2,585,904), where all-trunks-busy conditions are determined in the marker, the present system being faster due to the translator considering the availability of a route before it issues routing instructions.
