Abstract: 1,153,053. Coiling helices. ENGLISH ELECTRIC CO. Ltd. 3 Aug., 1967 [5 Aug., 1966], No. 35113/66. Addition to 1,018,954. Heading B3E. [Also in Divisions D1 and F2] A flexible hose or rope having a metallic outer surface is armoured by winding on to it a steel wire which has been heated to a higher temperature than the metallic outer surface, the hose or rope being rotated about a common axis defined by a pair of axially spaced apart guides and moved along the said axis, so as to define a straight portion of the hose or rope between the guides, the heated wire being drawn on to the straight portion so as to form, on cooling, a continuous flexible helical coil. In an apparatus for carrying out the method, the hose or rope 10 is drawn from a rotatable drum 20 and reeled up by a drum 34 after wire 13 from a spool 59 has been wound around it. The drums 20 and 34 are each mounted in carriers 21 and 35 respectively which rotate on stub axles supported in bearings 27, 28, 39 and 40, and are driven by chains 42 and sprockets from a shaft 44 which is driven by an electric motor through a change speed gearbox . The hose or rope passes through the hollow stub axles 26 and 36 and between a grooved roller 53 and a pressure roller 67. The roller 53 is driven through a worm 51 mounted on the same shaft as a sprocket 50 which is engaged by a chain which also passes round a sprocket 48 fixed to the stationary bearing 39. The wire 13 passes through a stainless steel guide tube 61 which is resistance heated to 900‹ C. If the hose has a tendency to twist the speed of one of the carriers relative to the other is varied by inserting a differential gear 69, Fig. 4, in the drive shaft to the take-up drum 34. The annulus 75 of the differential is connected by a chain to a hand wheel for manual adjustment of the speeds as necessary, or is connected to a pawl and ratchet or variable speed drive mechanism for continuous rotation of the annulus.

Title: Improvements in and relating to devices for centering containers on the tables of container sealing machines, such as can seaming machines
IPC: B21D51/32
Filed: 1933-12-14
Abstract: 430,419. Applying capsules &c. CHORLTON, F. O. L., Riverside Works, Bury. Dec. 14, 1933, No. 35163. [Class 125 (ii)] [See also Group XXII] A machine for sealing bottles, jars, &c. by means of a cork cap, or like stopper, comprising an axially movable table on which they are held in correct relation to the sealing mechanism and to which they may be fed by automatic means, has two or more centring devices symmetrically disposed on the table which are moved radially to centre and hold the container by axial movement of the table relatively to an actuating part. The invention is described with reference to a seaming-machine and the apparatus comprises a shaft D carrying cams for operating the parts of the machine as in Specification 430,418, [Group XXII]. The seaming-tools c5 are moved radially during seaming by a cam c41 reciprocated by a cam c1 and lever c11. The table P supporting the container J is raised to seaming position by a cam p1 through a rod p3 and a bell-crank lever p6, p8 engaging the hollow shank p12 of the table. A member t1, carrying circular rack teeth t15 engaging toothed portions t16 of centring devices T, is moved upwardly by frictional engagement with the sleeve p12, but the movement is partly restrained by a spring t13, the relative motion causing the devices T to swing into engagement with the container due to the engagement of the teeth t15, t16. In a modification an adjustable friction bearing replaces the spring t13. In a further modification, movement of the table relatively to a sleeve t32, Fig. 5, moves centring devices T2 inwardly through levers t34, the devices being applied to non-circular cans. A pin and slot connection may replace the levers t34. Specification 430,420 also is referred to. According to the Provisional Specification, the actuating part may be moved positively in the axial direction relatively to the table to actuate the centring devices.

Title: Semiconductor double heterostructure diode laser
IPC: H01S5/227
Filed: 1972-07-28
Abstract: 1385818 Lasers LICENTIA PATENTVERWALTUNGS GmbH 28 July 1972 [29 July 1971] 35500/72 Heading H1C In a double heterojunction semi-conductor laser diode current is restricted to a narrow portion of the laserable region by insulating layers or by depletion layers. A conventional restricted current diode which the invention modifies will first be described. In Fig. 2 a P type material on a heatsink M forms a P-N junction with the upper N type material; the junction is the light emitting region. Two P type regions are formed in the N type material by masking and diffusing, leaving a narrow N type path through which current is passed by electrodes (not shown) at the top and bottom of the device. The depletion layers around these two P type regions restrict the current so that lasing occurs only in the region at the centre of Fig. 2; such an output is suited to fibre optic coupling. The P and N type materials may be reversed, and the heatsink may be at the top of the device, Figs. 3-5 (not shown). In the invention the simple P-N junction may be replaced by a layer a, Fig. 6, of compensatedly doped material having regions of higher band gap, P+ and N+ on either side of it to form a double hetero-structure laser and hence confine emitted radiation to layer a. Again the P and N type materials may be reversed, and heatsink M may be at the top of the device, Figs. 7-9 (not shown). If the P type regions of Fig. 6, which define the current path are grown first, and then the rest of the structure is produced on top of the regions, the final laser is as shown in Fig. 10. Again the materials may be reversed, Fig. 11 (not shown). If the current is to be confined by insulating layers, the structure of Fig. 13 is used; here portions are first etched away and then insulating material F, of lower refractive index than the active material a, is deposited. The remaining space is filled with a material G. In Fig. 13 layers v and ware of higher bandgap than layer a, and may be GaAlAs, while S is a substrate, e.g. of GaAs. Layer d prevents corrosion. The substrate may have depletion layers formed in it as for Figs. 2-11 to further confine the current. The region G may be omitted, but surface insulation with SiO2 is then preferred, Fig. 16 (not shown). In Fig. 14 the region a is restricted in width by the layer w, to further confine the current path between the depletion layers formed in substrate S. The above current restriction may be combined with conventional strip electrodes. The output may be a transverse mode suitable for coupling to an optical fibre.

Title: Improved platinum contact catalyst for the oxidation of nh to no
IPC: C01B21/26
Filed: 1957-11-14
Abstract: <PICT:0824479/III/1> In an Ostwald converter composed of two concentric tubes, the inner one of which carries a pad formed by coiling two platinum strips, one being flat and the other crinkled, the platinum pad is situated over a stack of two or more platinum gauzes the meshes of which have a smaller diameter than the channels in the pad.  A typical pad has a diameter of 60 to 140 mm. and weighs 50 to 250 g. being formed from platinum strips 10 to 20 mm. wide and 0.01 to 0.02 mm. thick.  As the number of gauzes is increased the width of the platinum strips can be decreased (e.g. to 6 mm. for 9 gauzes). The surface area of the channels in such a pad will be 0.5-1 mm.2.  In an example a pad 8 has triangular channels equivalent in cross-section to 1 mm. diameter tubes and is supported by 5 gauzes 9 composed of 0.06 mm. platinum wire and having a mesh size of 0.25 mm. 11.5 vol. per cent NH3 mixed with air is introduced into the converter via pipe 3 and passes through the pad 8 and gauzes 9 (90% Pt/10% Rh) and cut through the inner tube 2.  With the platinum at 850 DEG  C. and a pad diameter of 135 mm. the capacity of the converter is 14 m.3 (N.T.P.) per hour.  The apparatus is also suitable for the conversion of NH3 to HCN by reaction with, for example, methane. Specifications 698/1902 and 8300/1902, [both in Class 1], are referred to.

Title: Improvements relating to rack and pinion adjusting devices
IPC: F16H19/00
Filed: 1961-10-03
Abstract: 938,906. Sharpening cutters. GLEASON WORKS. Oct. 3, 1961 [Oct. 18, 1960], No. 35665/61. Class 60. [Also in Group XXIV] In screw-operated rack and pinion gearing for effecting angular adjustment and clamping of a member 11 relatively to a member 10, e.g. in a cutter-sharpening machine, a segmental pinion 13 on the member 11 is engaged by the two sets of teeth on tubular telescopic racks 14, 15, Fig. 2, which are initially moved in unison to effect the adjustment and subsequently moved relatively to each other to take up backlash. The rack 15 has a threaded bore engaged by an adjusting screw 21 slidably keyed to an operating dial 23. The rack 14 is secured to a nut 16 engaged by a tubular adjusting screw 17 coupled by a pin and slot 22 to the screw 21, the rotatable screw 17 being axially located relatively to the member 10 by a flange 18. The screws 17, 21 have the same lead so that manual rotation of screw 21 (e.g. by dial 23 or by a wrench) causes simultaneous adjustment of the two racks and hence of the member 11. Rotation of the racks 14, 15 is prevented by the pinion 13. After adjustment a nut 25 on the end of screw 21 is tightened to cause relative axial movement between the two screws 17, 21 and thus between their associated racks to take up any backlash and to clamp the member 11 in its adjusted position. Preferably a spring (not shown) between the two racks acts to take up backlash during adjustment. Before clamping by the nut 25, the member 11 may be adjusted axially relatively to the member 10 by rotation of a shaft 26 eccentrically carrying a roller 27 engaging a transverse slot in the member 11. In a modification allowing a pinion 33, Fig. 3, to be moved hydraulically relatively to a support 30 between two positions predetermined by adjusting screws, and to be hydraulically clamped, the pinion 33 is simultaneously engaged by telescopic tubular racks 34, 35 secured to respective nuts 37, 38 on telescopic screws 39, 41 coupled by a pin and slot 43. One end of screw 39 is splined to a shaft 44 which can be rotated to adjust the racks by a dial 45 and can be clamped by a nut 46. Rotation of a second dial 51 turns a screw 49 to adjust the axial position of a stop nut 48 slidably keyed in the support 30, a clamp nut 52 being provided. The ends of the screws 41, 39 are formed as telescopic pistons 42, 47 so that application of hydraulic pressure to chamber 54 firstly moves the two pistons and racks to the left until piston 42 abuts shoulder 55 and secondly moves piston 47 further to take up backlash and clamp the assembly in the adjusted position determined by dial 45. Application of hydraulic pressure to chamber 57 firstly moves the two pistons and racks to the right until piston 47 abuts stop nut 48 and secondly moves piston 42 further to take up backlash and clamp the assembly in the adjusted position determined by dial 51. Specification 938,904 is referred to.
