Abstract: 1,230,766. Making heat exchangers. W. H. PAUL Ltd. 23 July, 1968 [28 July, 1967], No. 34709/67. Headings B3A and B3Q. [Also in Division F4] A heat exchanger is made by joining together at their edges two metal sheets 2, 3 and then, by fluid pressure applied between the sheets, distorting both sheets outwardly to provide a fluid flow space between the sheets except at a plurality of discrete localities 7 where external pressure is applied to prevent such distortion. An apparatus for making the heat exchanger is shown in Figs. 4 and 5 and consists of members 10, 11 (e.g. tubular members) spaced apart sufficiently to allow positioning of the pair of metal sheets between them, the sheets having been previously joined together at their edges. At each of the said discrete localities are plungers 17a, 17b, Fig. 5, slidable in apertures in the members 10, 11 so that when an assembly comprising cam members 22, 24 carried on a plate 26 is lowered e.g. by a hoist 27, 28, into position alongside the members 10, 11, the plungers 17a, 17b are forced into contact with the sheets 2, 3 so preventing bulging out of the sheets at these points when fluid pressure is applied subsequently between the sheets. The members 10, 11 are spaced sufficiently to prevent undue bulging out of the sheets between the discrete localities. In the preferred form of heat exchanger the sheets 2, 3 are cylindrical and in the apparatus shown for making such a heat exchanger the members 10, 11, 22 and 24 are cylindrical. Inlet and outlet connections 8, 9 are connected to the heat exchanger and the pressurizing fluid is applied through these connections. Longitudinal slots 31 are formed in the members 10 and 22, as shown in Fig. 4, to permit withdrawal upwardly of these members together with the member 24 when the operation of making the heat exchanger has been completed.

Abstract: 1,238,200. Aerials. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING A.G. 29 Nov., 1968 [1 Dec., 1967], No. 56879/68. Heading H4A. An aerial comprises a coaxial transmission line 2 the lower part 1 of the outer conductor 5 of which is subdivided into segments 6, 7 near its end by two diametrically opposite slots 3, 4 of lengths #‹/2 (# o  = mean operating wavelength). The said lower part 1 is of larger internal diameter than the feeder line and a quarterwave transformer extending from the tops of the slots to a step 19 provides matching means. A transverse cross-sectional plane through the centres of the slots is termed the coupling plane, and a conductive member 9 centered thereon joins the segment 6 to the inner conductor 8 of the line. A short-circuiting disc 10 terminates the line at a distance of from 5/16#0 to 7/16 #0  from the coupling plane and provides capacitive coupling for the segment 7. The effective impedance valves of the couplings to the two segments are arranged to be equal and opposite at the mean operating frequency. A sleeve 13 has a base 16 which is level with the bottoms of the slots 3, 4 and it extends upwardly outside the outer conductor 5 of the line and past the slots. Additional coupling screw elements 11, 12 centered on the coupling plane are provided on the outsides of the segments 6, 7. An insulating cap on the sleeve 13 comprises a sleeve 17 and a frusto-conical end 18. Waves of the TE 11  mode are generated between the outer conductor 5 and the sleeve 13, and linearly polarized radiation is consequently directed upwardly. The aerial may be used as a primary feed for a parabolic reflector, and the insulating cap on the sleeve 13 may be so shaped as to improve the uniformity of illumination over the said reflector.

In a photographic camera, shutter release is prevented if the subject brightness is too low or too high for the selected exposure aperture respective warming lamps being lit. Prior to exposure, an iris disc 46 is rotated to position a selected aperture 49 123  adjacent the lens aperture 48, an appropriate resistance r 345  being connected in the control circuit. (a) Excess brightness. On depressing release 1, contacts Sa 123  engage contacts Sa 467  connecting a resistor r 1  into the circuit and short circuiting a resistor r 2 . The resistance of a photo-resistor P is less than that of r 1  so a transistor T 1  is non- conductive and an electromagnet 45 is notenergized. On depressing release 1 a member 27 is moved downwards by a spring 30 pushing a crank 41 out of its path (since the electromagnet 45 is not energized) and releasing stop 14 which rotates into the path of release 1. This prevents further movement of release 1 and thus of a member 20, and shutter blade 26 fixed to member 20 still covers the aperture 48. The movement of member 27 also engages switch contacts SC 1  and Sc 3 , lighting a warning lamp A 1 . (b) Normal brightness. When release is effected as above, the resistance of photo-resistor P is greater than that of r 1 , so that electromagnet 45 is energized, crank 41 blocks member 27, stop 14 is not freed, and release 1 continues its downward movement to disengage contacts Sa 13  from contacts Sa 47  and connect resistor r 2  in circuit. The resistance of photo-resistor P is less than that of r 1  + r2 so that electromagnet 45 is deenergized and member 27 moves and releases stop 14, the end 16 of which moves out of the path of release 1, the latter having moved too far to be blocked by the end 15. Contacts Sa 13  now engage contacts Sa 58  connecting photo-resistor P to the negative side of battery E and thus energizing electromagnet 45 so that crank 41 blocks member 27. Release 1 continues to move moving a crank 9 from the path of member 20 so that the latter can move to move blade 26 and uncover aperture 48 and open a switch Sb to allow a capacitor C to charge and de-energize the electromagnet. Crank 41 thus releases member 27 which moves to close the shutter with a blade 40. (c) Insufficient brightness. When release is effected as in (b), the resistance of photo-resistor P is greater than that of r 1  + r 2 , electromagnet 45 remains energized, member 27 is blocked after just a short degree of movement and, when release 1 has engaged contacts Sa 13  with contacts Sa 58  to light lamp A 2 , further movement thereof is prevented by end 16 of crank 14.

Thus each time a bore 5 in the piston 2 aligns with a groove 11 in the control piston 10, delivery is terminated since fuel is spilled to an inlet chamber 7 through the groove 3 and bores 13, 12, 6. Fuel enters the pumping chamber 8 through the groove 3 when it connects to the suction chamber 7. The control piston is manually or hydraulically adjustable. As shown, the adjustment is automatically caused by fuel pumped from an auxiliary chamber 15 by a piston extension 14. Fuel is supplied to a passage 19 and attains a pressure dependent on the pump speed and the setting of a throttle 23 in a discharge passage 18. The pressure in the passage 19 acting on the end 21 of the piston 10 determines the amount of compression of a spring 22 and thereby the axial position of the control piston.

Abstract: 1328675 Fluid-pressure servo-motors DIESELMOTORENWERK ROSTOCK VEB 3 Oct 1970 47126/70 Heading G3P [Also in Divisions B1 F2] Liquid to be filtered is pumped from tank 16 through pipeline 20 and two-way, hydraulic slidevalve 11 to filter 17 whence the filtered liquid flows to an appliance 19; but as the degree of soiling of filter 17 increases, the pressuredifference across it is communicated by liquid in pipelines 24 and 25 to opposite sides of piston 7 in slide-valve 3 so that the piston is pushed towards the left and spring 6 is compressed. When the pressure-difference reaches a prescribed minimum value, piston 7 withdraws a locking- bolt from rotary switch 4 releasing spring 6 which rotates switch 4 whereby the control pipelines are exchanged so that pipeline 25 which has been hitherto connected with pipeline 27 via grooves in valve 3 is now connected with pipeline 28; and pipeline 29 is connected with pipeline 27. This exchange causes the piston 12 in valve 11 to slide so that it closes pipeline 20 to filter 17 and opens it to filter 18. The liquid still in valve 11 is forced via pipelines 27 and 29 into time-control slide-valve 8, causing spring 10 to be compressed, filtrate-backflushing circuit 22 to open, and valve 3 to bleed through pipeline 26. The backflushing liquid flows through soiled filter 17, valve 11, pipeline 22 and valve 8 to settling tank 2. Bleeding of valve 3 via pipeline 26 causes piston 7 to be pushed back to its starting position by the pressure of the filtrate in pipeline 25. When the time-control piston 9 reaches its terminal position, pipeline 22 is closed and backflushing is over. The control circuits include choke-valves 13, 14, 15.
