IPC: H01S3/041
Filed: 1968-11-29
Abstract: 1,193,565. Lasers. COMPAGNIE GENERALE D'ELECTRICITE. 29 Nov., 1968 [30 Nov., 1967; 21 March, 1968; 3 April, 1968], No. 56909/68. Heading H1C. In order to cool the anode of a gas laser the anode is constructed in two parts provided with cooling passages and interconnected by two metal tubes which act as supply and return conduits for a liquid coolant. The active part of the anode is in the form of a hollow annular part 1 which defines in conjunction with cover 2 a coolant passage and is mounted on to two metal tubes 5, 6 extending from grooves 8, 9, respectively, in a base 7. The two grooves 8, 9 together with plate 10 form two further passages into which extend two further tubes through holes 12, 11. A coolant supply is connected to the two further tubes, Fig. 1 (not shown), so that the coolant liquid flows through groove 8 into and through tube 5 and into the annular part. The return is through tube 6, into groove 9 and out through the other further tube. The anode assembly may be mounted into the gas laser tube 21, as shown in Fig. 3, and the base 7<SP>1</SP> is secured to the ring 20 fixed to the laser tube 21 by a series of bolts 25 screwed into holes 22. Base 7<SP>1</SP> is provided with studs 18 which fit into recesses 19 in ring 20 to locate the Brewster angle plate 17 at the required angular position relative to the tube axis 23. Electrical connection is made to the anode by means of supportring 15 or by the two further tubes when they are made of metal. In order to avoid point effects during electric discharge of the laser the end of the part 1 is rounded and polished, Fig. 4 (not shown).

Abstract: 1370615 Jointing by forging; swaging; stamping; crimping BTR INDUSTRIES Ltd 28 Oct 1971 [3 Dec 1970] 57496/70 Headings B3H and B3Q  Apparatus for crimping or swaging a tube on to a component located within the tube comprises a ring of spaced, radially-extending dies 10, a support 12, 15 at one axial end of the ring, means (22), Figs. 3, 4 (not shown) to mount the dies independently on the support for radial sliding movement with respect to the axis 11 of the ring, a member (not shown) having a bore in which the ring is engageable, the bore of the member and outer surfaces of the dies both being shaped so that relative movement of the member and ring displaces the dies radially inwardly, and means for effecting movement of the member and ring, the dies being generally wedge-shaped when viewed along the ring axis so that the outer surfaces of the dies are wider than the inner surfaces nearest the axis. The ring of dies is mounted in two halves on plates 12, 15, the plate 12 being secured to a vertical platen 14 of a press and plate 15 slidably mounted on platen 14 within guides 16, thus allowing separation of the ring halves to enable the tube to be inserted into the dies. Cylinder 19 and piston-rod 21 are utilized for moving plate 15. Each die 10 is mounted by means of a slide (22) to its respective plate and comprises a die shoe 28 and die finger 29. The outer surface of each shoe is part-conical so that they will be accommodated by a collar which is slidably mounted on rods 30 fixed to platen 14 which causes the fingers to move inwardly and swage or crimp the tube. The dies are resiliently urged apart when not acted upon by the collar so as to move outwardly. The ring halves are connected together at both ends by springs (34), Fig. 3 (not shown), co-operating with sleeves (33) which limit the separation of adjacent dies, which dies have compression springs (50) in their opposite facing bores (32). The fingers 29 are detachable and are maintained within the shoes by way of studs (40), (43). The die fingers may be of different form, Fig. 4 (not shown), for crimping or swaging different size tubes. The cylinder and piston assembly is pneumatically controlled and the collar is driven by a double acting hydraulic ram. Modifications of the apparatus include varying the join between plates 12, 15 and the movement of plate 15 to one side instead of vertically by using a pivoted arm.

Filed: 1973-12-21
Abstract: 1430400 Radio receiving circuits BBC BROWN BOVERI & CO Ltd 21 Dec 1973 [27 Dec 1972] 59606/73 Heading H3Q The invention relates to a stop-on-signal receiver with voltage controlled oscillator, in which the sweeping voltage is replaced by the output of a frequency discriminator when a signal falls within the passband of the I.F. amplifier, under control of a logic circuit controlled by an instantaneous value detector connected to an I.F. stage. It is characterized in that the change-over only occurs when the I.F. output signal approaches the peak value, or a specific fraction thereof, of the peak value of the output signal, stored during a preceding search operation over the whole tuning range. The receiver comprises voltage-controlled oscillator 1, mixer 2, I.F. stages 3, 4, discriminator 5 and integrator 6, and is controlled by logic circuit 11. The switches are initially in the positions shown, and a first search over the whole tuning range is performed, by means of the voltage from source 8 applied to integrator 6; during this search, peak detector 14 charges up to peak value of the strongest signal intercepted. At the end of the first search, switch 18 is closed, discharging integrator 6, and then reopened to commence the second search. The output from instantaneous value detector 9 is compared with the stored output from peak detector 14 in comparator 10, the output from the peak detector 14 being applied to the second input of the comparator 10 via voltage follower 15 and potentiometer 16, 17; when the output from instantaneous value detector 9 exceeds the voltage across resistor 17, logic circuit 11 is activated to open switch 7 and close switches 12, 18, 19 whereby the output of the frequency discriminator takes charge and peak detector 14 is discharged. The arrangement so far described is also shown in Fig. 2; the arrangement of Fig. 4 also includes a circuit which measures the signal to noise ratio and prevents switchover if it is below a predetermined value. A further integrator 29 is provided, coupled by diode rectifier 31 and switch 30 to the output of I.F. stage 4; at the commencement of the first search, switch 32 is momentarily closed to discharge integrator 29. During the first search switch 30 is closed, and the output of integrator 29 charges to a value representing the total noise across the whole tuning range. This is compared in comparator 33 with the output from peak value detector 14, via voltagefollower 15; if the resulting voltage, representing the signal to noise ratio is not satisfactory, logic circuit 11 is inhibited from switching over to frequency-discriminator control. The Specification also describes the logic circuits used (Fig. 3, not shown).
