Patent GB-906022-A (GB)
Title: Improvements in or relating to methods of metallising ceramic surfaces
Inventor: BEAN LEONARD WILLIAM
IPC: C04B37/02
Filed: 1958-06-06
Abstract: The surface of a ceramic body is metallized by coating it with particles of Mo and/or W and/or one or more of their reducible oxygen-containing compounds, together with particles of titanium hydride and/or zirconium hydride, and heating the coated surface to produce an at least partly vitrified layer containing titanium oxide and/or zirconium oxide with particles of Mo and/or W bonded to it. Preferably the weight of the Ti and Zr atoms lies in the range of 1-20% of the total metal atoms present in the coating. The particles may be applied as an intimate mixture in suspension, for example, in an ethyl lactate solution of pyroxylin: alternatively, they may be applied as separate layers of the different ingredients.  The coated surface is heated at 1200-1600 DEG  C. in an atmosphere non-oxidizing to Mo and W, e.g. in wet hydrogen, a rare gas or in vacuo.  Among ceramic bodies which may be coated are those consisting wholly or mainly of alumina, steatite or forsterite.  Bodies metallized in this way may be joined to metal bodies or to a metallized surface of another ceramic body by soldering or brazing.  Alternatively, two ceramic bodies may be joined in a single operation by interposing a layer of Mo &c. between abutting surfaces of the bodies and then heating.  The invention is particularly described with reference to the manufacture of a composite ceramic-metal envelope for a semi-conductor junction rectifier.

Title: Improvements in or relating to Carrier Telephony Equipment
Inventor: BAYLISS ALAN JOHN
IPC: H04J1/18
Filed: 1966-04-26
Abstract: 1,178,693. Intercommunication systems; combined radio receiving and transmitting systems. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 2 June, 1967 [26 April, 1966], No. 18224/66. Headings H4K, H4L and H4R. In a carrier telephony intercommunication system each substation incorporates a local oscillator which is used both to frequency change incoming signals to an intermediate frequency to be amplified in an i.f. amplifier, and also as a carrier frequency for outgoing signals. The local oscillator in each substation is normally tuned to a frequency different from that of any other substation but is tunable to any one of a number of other frequencies to allow communication with any other substation on that substation's frequencies. Fig. 3 shows a substation circuit in which the local oscillator 22 comprises a self oscillating mixer tunable by push-buttons 1-20 to any one of 20 oscillator frequencies one of which is the normal call receiving frequency for the set and the remaining 19 allowing communication with any one of 19 similar sets. Incoming signals are fed from a coaxial line 21 to the base of mixer 23 through the tuned circuit 24, the i.f. signal being obtained in the collector circuit and fed via tuned transformer 26, i.f. amplifier 37, detector 38, and a.f. amplifier 39 to the receiver 40. Speech signals from the microphone 36 modulate the collector voltage of transistor 23, via the a.f. amplifier 35 and transformer 28, and cause the oscillatory output of the transistor to be amplitude modulated by the speech, the resulting signals being fed to the coaxial line via the output tapping on the oscillator coil 28. Normally, in a listening or called condition, the input circuit 28 is tuned to a frequency in a band from 985 to 1365 kc./s., at a frequency 470/kc./s., the i.f., below the output circuit 29, i.e. the oscillator or carrier output frequency, the different substations of one system being tuned to frequencies with 20 kc./s. spacing. On depression of a button to call another station the carrier output or oscillator frequency of the calling station is tuned to the input circuit frequency of the called station and the input circuit frequency of the calling station is tuned to a frequency 470 kc./s. above the oscillator frequency to be able to receive the carrier frequency output signals of the called stations. The calling buttons of each substation are arranged to have a non-locking overtravel which operates contacts 41 to connect the a.f. amplifier 35 as an oscillator to generate a calling signal, and each substation has a reed relay hook switch, see Specification 1,178,695, operated by a magnet in the hand set, to reduce the output level of the calling tone when the hand set is lifted, so as to prevent ear damage due to the high level at which the calling tone is produced.

Title: Process for the recovery of lower aliphatic acids used in the esterification of cellulose
IPC: C08B3/26
Filed: 1948-07-07
Abstract: Aqueous solutions of aliphatic acids containing less than six carbon atoms in the molecule, which solutions contain cellulose esters dissolved or suspended therein (e.g. as recovered from the process of producing cellulose esters), are treated to recover the acids by heating to a temperature of 215-250 DEG  C. under sufficient pressure to maintain the solution in liquid form until substantially complete hydrolysis of the cellulose ester is effected, e.g. a period of 5-20 minutes.  The aliphatic acid is subsequently separated from solution by solvent extraction.  The process may be continuous.  Examples describe the preparation of acetic acid from cellulose acetate solutions obtained in the preparation of cellulose acetate.  Other cellulose ester solutions referred to are those of the propionate, butyrate, acetate-propionate, and acetate-butyrate.

Title: Improvements in apparatus for loading and ramming projectiles in guns
IPC: F41A9/42
Filed: 1923-07-19
Abstract: 202,290. Schneider et Cie. Aug. 8, 1922, [Convention date]. Loading-appliances. - Relates to ammunition loading and ramming apparatus of the kind in which the rammer is automatically operated by a recuperator energized during recoil, such operation being timed to suit the movements of the loading tray. According to the invention, the space occupied by the rammer at the rear of the gun is reduced by making the final part of the ramming movement a pivotal one effected by a cam interposed in the path of the rammer by the transverse loading movement of the loading tray. The rammer E, pivoted on the rear end of the piston-rod D of a hydro-pneumatic recuperator F, recoils with the gun A, and is retained in the recoiled position by a spring-pin d engaging behind a guide-rail b. The movement of the loading-tray C into line with the breech opening operates through gearing G, G<1>, G<3> to rock a toothed sector H, the movement of which first raises a cam I into the path of a roller e<1> on the rammer and then, through rods H<1>, H<2>, releases the pin d. The ammunition is then rammed from the tray C by a rectilinear movement of the rammer, until the roller e<1> engages the cam I to make the last part of the movement, a pivotal one about the pin e. The movement of the loading- tray away from the gun lowers the cam I, the part i<2> of which rocks the rammer back to the upright position.
