IPC: B21D53/04
Abstract: 1,052,061. Making composite heat-exchangers. REYNOLDS METAL CO. Sept. 24, 1963, No. 37610/63. Heading B3A. A bonded composite sheet comprises two outer layers and an intermediate layer metallurgically bonded together, the intermediate layer having a lower strength than the outer layers. The intermediate layer is subsequently split and inflated by fluid under pressure to produce a system of passageways therein whilst the composite is held between dies which define the passageways. In an example a pair of aluminium alloy sheets containing 4À5% magnesium and 0À75% manganese and a pair of aluminium sheets having a purity of at least 99% are annealed at 750‹ F. for 1 hour, allowed to cool, wire brushed, reheated to 750‹ F. and each of the aluminium sheets clad to the respective alloy sheets by rolling to effect a reduction of 10-15% to produce a thickness of 0À125 inch. Each of the clad sheets is subsequently annealed at 750‹ F. for 1 hour, brushed, the pure aluminium faces thereof placed together. the corners tack-welded together, the assembly heated to 850‹ F. for 1 hour and roll bonded to a thickness of 0À60 inch followed by annealing at 750‹ F. and slow cooling for 1 hour. A single inner layer or two spaced apart inner layers may be used. The strip may be coiled, until required for further use. A section of strip which is subsequently cut off and which may be preheated to 600‹ F., is located between dies, a portion of the inner layer split and a needle inserted therein for application of fluid pressure, e.g. air, nitrogen, water vapour, water or oil to effect expansion thereof. The layers may be initially cast prior to rolling which may be carried out in a number of passes some of which may be in a direction 90 degrees to the initial bonding direction. The composite sheet may be stamped, bent or drawn before being inflated and may be divided into sections by severing along transversely located short layers of stop weld which also facilitates the initial insertion of the inflation needle. Heating may be carried out by thermostatically controlled electric resistance heaters or ovens. The internal roughness of the passageways may be smoothed by passing chemical brightening solutions or abrasive slurry, e.g. suspended alumina therethrough, flushing with water and drying. The thickness of the inner layer after rolling is not less than 0À0001 inch but is preferably within 0À004 to 0À020 inch. The aluminium alloy preferably contains from 0À8-6% magnesium. Other metals, e.g. copper, silver, titanium or stainless steel or combinations thereof may be used. Articles such as refrigerator evaporators or condensers, tubing, radiators, radiant heating panels, rigid structural and decorative panels, floatable sheets and containers may be made by the process. Structural panels may be strengthened by filling the spaces with foamed plastic.

Abstract: 1,103,317. Making polyamide composite filaments. FARBENFABRIKEN BAYER A.G. 13 May, 1965 [15 May, 1964; 7 Jan., 1965], No. 20267/65. Heading B5B. Crimped conjugate bicomponent polyamide filaments consisting of two components which are bonded together along the whole length of the filament in side-by-side relationship are produced by melt-spinning a modified polyamide containing 0À5 to 20% of a modifying sulphonic acid segment having the general formula wherein R<SP>11</SP> is a -(CH 2 ) x - group, x and y each represent an integer from 2 to 12, R and R<SP>1</SP> each represent a hydrogen atom or a group -(CH 2 ) z -SO 3 Me, in which z represents an integer from 4 to 6 and Me represents an alkali metal or hydrogen, the group -(CH 2 ) z -SO 3 Me, being present at least once in the segment, and a polyamide which does not contain sulphonic acid groups, the two types of polyamide being extruded into air through a common spinneret orifice to form the composite filament at a temperature between 250‹ and 300‹ C., the filament thus formed being stretched at room temperature or at a higher temperature and treated with water at a temperature between 60‹ and 120‹ C. The process may be modified in that the symbol R<SP>11</SP> in the above general formula represents a cyclohexylene group or a group having the formula The ratios by weight between the two components of the composite filaments are advantageously between 5: 1 and 1: 5. The stretching step may be effected at a temperature between 20‹ and 140‹ C. In an example, an unmodified poly-#-aminocaproic acid and a modified poly-#- aminocaproic acid containing 5% by weight of the structural unit are simultaneously melt spun at 280‹ C. into air at 25‹ C. in such a manner that the rates of supply by weight of the polymers to each of the orifices of the spinneret are equal, the composite filaments thus produced are stretched at a stretch ratio of 3À5: 1 at 80‹ C. and thereafter treated with water at 90‹ C. and dried while in the relaxed state.

Abstract: 1,229,414. Aircraft instruments. SPERRY RAND Ltd. 10 July, 1968 [18 July, 1967], No. 32993/67. Heading B7W.  In a duplex arrangement of instruments of the kind described in Specification 1,071,882 for use particularly during an "overshoot", each instrument is constructed to show and compare one with the other, the deviation from a predetermined optimum relationship between the acceleration as measured both along and normal to the longitudinal axis of the aircraft and the pitch attitude of said axis to a horizontal plane, whereby a null reading of each instrument, i.e. by maintaining director bar 25 aligned with the fixed symbol 27, defines a desired acceleration/climb flight path. Each instrument comprises a vertical gyro 30 supplying pitch and roll signals 0 and # to position a spherical indicator 31 of an attitude director 26 and an overshoot computer 29 shown in detail in Fig. 3 which receives a pitch signal # from the gyro 30 and comprises a longitudinal accelerometer 11 mounted so that its sensitive axis lies at a small angle # 0  to the aircraft's longitudinal axis whereby the accelerometer supplies a signal f representing accelerations both along and normal to the aircraft's longitudinal axis. The signal f is corrected for # 0  by a potentiometer 32, shaped by circuit 33 and algebraically summed at 34 with pitch signal # according to the relationship f-b# where b is a constant selected for a particular aircraft to form a pitch demand signal X from which is then subtracted a rate-of-pitch signal c# formed by a phase advance circuit acting on the pitch attitude signal at 35. The resultant modified # signal is amplified and applied through a two-position switch 36 to the director bar 25 as well as to an auto-pilot 37 and a comparator 38. Pitch signals # from each instrument are compared at 39. In a normal landing approach glide path signals are applied on lines 40 via switch 36 to the director bar 25. A desired flight path may also be defined by applying signals f and # to separate indicators which are maintained in alignment (Fig. 2, not shown). In a further embodiment (Fig. 6, not shown), the pitch demand signal # is further modified should the acceleration signal f exceed a predetermined threshold so that the pilot is directed into a less steep climb.

Exposure classification apparatus for classifying originals to be printed, which originals have a subject and a fore or background, comprises an array of photo-cells having first and second areas, the first area 2 including a plurality of relatively small photo-cells e.g. 3; the second area surrounding the first area and including a single photoresponsive device 1 larger than any of the photo-cells of the first area. The output of each of the first area photo-cells and of the perimetrical device 1 is brought out to a circuit Fig. 2 (not shown) including an auctioneering function (4) and a summing function (5). The former determines which of the first area photo-cells is presented with the extreme density and feeds to the summing function an output which is an analog of that extreme density. This output and that of the device 1 are summed to give a classification output which controls the exposure of the print. The first area photo-cells may be arranged in inter-digitated sets, the sets having differing spectral sensitivity. The term "extreme density" is used to denote the maximum density of a negative original or the minimum density of a positive original.

Abstract: 1,231,945. Colour television. AMPEX CORP. 14 March, 1969 [18 March, 1968], No. 13612/69. Heading H4F. The chrominance component of a colour television signal is separated from the luminance and synchronizing components and means are provided to invert selectively the phase of the chrominance component in response to a command signal prior to reconstitution of the composite signal. In the embodiment a low-pass filter 21 separates the luminance and synchronizing components into a first channel 11 while the chrominance component is selected for a second channel 12 by a band-pass filter 23. Any differences in time delay between the filters 21, 23 are compensated by an equalizer 24 in the first channel 11, and a buffer amplifier 22 prevents interaction between the filters. The selective chrominance phase inverter 14 comprises input and output transformers 27, 28 whose respective secondary and primary windings 32, 33 are coupled by two opposite polarity diode loops 34/36, 37/38, one of which is conductive dependent upon the relative bias between two centre taps 42, 43 on the windings 32, 33. Phase inversion is produced by the application of a positive-going command signal C H  at an input 16, which signal renders two transistors 46, 53 in a biasing network 44 conductive and hence applies a positive bias to the centre tap 43. This renders the diode loop 37/38 conductive, cross-coupling the windings 32, 33 and thus applying the necessary phase inversion to the chrominance component. In the absence of the command signal C H  the tap 43 is negatively biased, the windings 32, 33 are directly coupled and no phase inversion is applied. Finally the composite television signal is reconstituted in an adder 17. The invention is applicable to systems in which fast, slow or reversed motion play-back is required.
