Title: Manufacture of food container and the like from aluminum foil or other thin metallic material
Inventor: EICHNER FRANK LAWRENCE
IPC: B31B50/88
Filed: 1960-08-08
Abstract: 956,710. Making food containers. REYNOLDS METALS CO. Aug. 8, 1960, No. 27452/60. Headings B3A and B3Q. [Also in Division B8] A method of making a food container from aluminium or aluminium alloy sheet material 0.0015 to 0.006 inches in thickness comprises the steps of simultaneously embossing and work hardening the sheet with a pattern of closely adjacent undulations which cause the .sheet to have an apparent thickness of 130- 200% of the un-embossed material and forming said sheet into a container. Fig. 1 shows the type of pattern 22 produced on a sheet 20, on the scale 21 shown under the Figure the distance D represents 0.5 inch. The material is rolled between rolls 26 (Fig. 13) annealed in a furnace 30, further reduced if desired by rolls 34 and then embossed by rolls 36 which may comprise two rigid co-operating rolls, or one rigid roll and one resilient roll. The stiffness of the embossed material is such that the thickness of the stock used may be reduced by 0.0005 to 0.001 inch while retaining the strength of a container made from plain sheet. The drawing characteristics of the material are improved by the extra material available for forming at sharp corners and by the more even tension maintained on the material by the pressure plates of the forming die since the increased apparent thickness of the material reduces the effect of variations in thickness of the plain sheet. Fig. 5 shows a dish 76 which has edges flanged at 90 and beaded at 88, and stiffening grooves 80, 82, 84 formed in the bottom. In view of the increased stiffness of the formed material these grooves may be omitted. In a modification only the bottom of such a dish is embossed, either by embossing selected area of the sheet from which the dish is made or by embossing the material in the forming die. Figs. 7 and 9 show a container 92 which has integral partitions 98 and 100 and edges which are flanged at 104 and beaded at 102. Fig. 10 shows a press tool 120 comprising a punch 122 and die 124 and pressure plate assemblies 134, 136, 138 and 140. The member 138 is stopped by the ring 146 before the bottom of the stroke and the flange 90 or 104 is produced by the members 134 and 138. The bead 88 or 102 is formed by the ring cavities 148 and 150 on the return stroke of the tool. The article is ejected by a knockout 160.

Title: Device for the limitation of the stroke of the control rod  of a fuel-injection pump
IPC: F02M59/44
Filed: 1971-06-11
Abstract: 1325827 Regulating fuel injection pumps FRIEDMAN and MAIER A G 11 June 1971 [13 June 1970] 27465/71 Headings F1A F1B The stroke of a fuel injection pump control rod 1 of an internal combustion engine is limited during normal operation of the engine by a slide 13 which is moved against a restoring spring 14 by a pressure medium derived either from the fuel injection pump or from the engine. The pressure medium may be derived from the engine lubricating oil, the pressure of compressed air from an engine driven compressor or the priming pressure of the fuel injection pump. The pressure is communicated via an annular chamber 24 to an oil chamber 22 where it acts on a diaphragm 16 to move the slide 13. At the engine starting position, Fig. 1 (not shown), a stop screw 7 engages a stationary stop 8. After the engine has started, the pressure in chamber 22 urges the slide 13 against the stop 7 until the control rod 1 is placed in a position of reduced delivery (Fig.4) either automatically or by the operator's action. This allows the slide 13 to move into position and limit further movement of the control rod 1 toward the starting position. The rate of movement of slide 13 may be retarded by a restriction in the pressure medium supply duct to chamber 22. The members 16 may be omitted and the oil pressure act directly on the slide 13. The starting and normal positions of the control rod may be adjusted by washer 6 and lock nut 9.

Patent GB-947807-A (GB)
Title: Control valve for a combined paper steering and power braking system
IPC: F15B11/20
Filed: 1961-07-31
Abstract: 947,807. Steering vehicles. BENDIX CORPORATION. July 31, 1961 [Sept. 6, 1960], No. 27700/61. Heading B7H. [Also in Division F2] A combined power steering and power braking system includes a power steering valve 18, Fig. 1, a pump 12, a reservoir 22, braking means 38 and a control device 10. The latter comprises a power piston 102, Fig. 2, to actuate the braking means 38, a sleeve 48 having three spaced grooves 50, 52, 54 connected respectively to the reservoir 22, the pump 12, and the valve 18, a spool valve 58 slidably received in the sleeve 48 and including three spaced lands 60, 62, 64, the land 62 being operative with the groove 52 and proportioned to be of less width than the groove, and a centrally disposed axial bore 80 having a radial passage 78 to provide fluid pressure access to the power piston 102. Upon axial application of the spool valve 58 the sequential movement causes the land 60 to cover the groove 50, Fig. 4, and the second land 62 to throttle the flow of fluid between the second groove 52 and the third groove 54 to produce a back pressure which is communicated to the power piston. The second land 62 is moved to lapped relationship, Fig. 5, with the second groove 52 when there is a sudden increase in power steering requirements and the back pressure created by the power steering valve 18 exceeds the pressure required by the power piston. The land 62 and the groove 52 are proportioned to provide a change from throttling position to lapped position in response to increased power steering requirements with imperceptible axial movements of the spool valve 58 maintaining substantially constant braking effort. To apply the brakes the spool valve 58 is moved axially by a pedal 40 which forces the stem 92 towards the right, compressing the spring 94 against washer 95 held by a shoulder 96 of a link 100 whose ball end 101 forces the spool valve axially to the position shown in Fig. 4. Fluid under pressure then flows through passages 78, 80, to chamber 82 from which it passes through a small longitudinal passage 103 to act on the piston 102 whose head 110 acts on the hydraulic fluid 112 to actuate the braking means 38. Back pressure quickly builds up within the chamber 82 where it acts against the spool valve biasing it leftwardly to the position shown in Fig. 5. The spool will stay in this position in which leakage from groove 52 past land 62 will equal the leakage past land 60 into groove 50. Regardless of the brake operating effort, the pressure in 82 will build up at such a rate that counter reaction in chamber 82 moves the spool backwardly and noticeable reduction in the rate of fluid flow to the valve 18 will not continue of periods greater than 0.2 seconds. The maximum amount of effort that can be applied to the spool is by compressing the spring 94 through the distance d which is the clearance between the ends of sleeves 140 and 48. U.S.A. Specification 2,517,005 is referred to.

Abstract: 1,168,717. Spectroscopy. CARL ZEISS JENA VEB. June 16, 1967, No.27802/67. Heading G2J. In an arrangement for scattered radiation and fluorescence spectroscopy a parallel beam of radiation 3-5 impinges on a concave mirror 1 and is reflected as a convergent beam on to a convex mirror 2 having a common focus F with mirror 1 and common optical axis X-X parallel to beam 3-5, so that the convergent reflected beam from mirror 1 is reflected back to mirror 1 as a parallel beam of smaller cross-section. The beam thus decreases in cross-section as it approaches axis X-X and the whole beam is absorbed by the sample in the space between the mirrors. The mirrors may be formed as internal or external coatings on a sample cell whose walls are shaped to the form 1, 2. The mirrors may be spherical or curved parabolically in their meridional sections traversed by the optical axis and struck by the principal ray 3.

Title: Suppression of visible spangle in the hot dip coating of ferrous metal strip with zinc
IPC: C23C2/26
Filed: 1965-07-02
Abstract: <PICT:1117323/C6-C7/1> In the hot dip coating of a ferrous metal strip with molten Zn, visible spangle is suppressed by inducing a multitude of closely spaced spangles which are invisible or barely visible to the naked eye by applying to the freshly coated strip, at a point where the temperature of the molten Zn coating on the strip is from just above its solidification temperature to 40 DEG F. there above, a water solution of a reactive inorganic salt which is thermally decomposed on contacting the molten Zn coating, the salt being one which will thermally decompose at a temperature within the range of 175 to 550 DEG F. and release radicals reactive with metallic Zn or a salt which will hydrolize when added to water to form a reactive inorganic salt which is decomposable within the temperature range, the salts and their decomposition products being non-toxic and leaving no harmful, difficulty removable residues on the coated strip.  Specified inorganic salts which decompose at 175 to 550 DEG F. are dibasic ammonium phosphate, NaHCO3, sodium dihydrogen orthophosphate, ammonium borate, ammonium molybdate and ammonium sulphate. Hydrolyzable salts which may be used are sodium carbonate and trisodium phosphate.  The Fig. shows solution containing a reactive inorganic salt being sprayed on Zn coated strip 13a from spray heads 18 extending entirely transversely across the strip.  The height of the spray heads 18 above a molten Zn bath 11 is automatically adjusted such that the metal coating is molten as enters the spray but solid as it leaves.  A radiation pyrometer measures the strip temperature and by a signal to an electronic device 20 controls an electric hoist motor which raises or lowers the spray head and pyrometer.

Title: Improvements in or relating to high frequency electron-discharge tube apparatus
IPC: H01J25/24
Filed: 1950-11-17
Abstract: 680,597. Velocity-modulated tubes. SPERRY CORPORATION. Nov. 17, 1950 [Dec. 30, 1949], No. 28183/50. Class 39(i) An electron-discharger tube apparatus of the reflex-velocity modulation type comprises a plurality of resonant-space resonators of different resonant frequencies and means for varying the circuit, parameters e.g. voltage applied to the reflector electrode so that any one of the resonators may be excited selectively to oscillate at its resonant frequency. As shown the apparatus comprises resonant spaces 38, 39 of different frequencies constituted by metallic laminations 46 to 50 and a separating wall 49 supported by a tube 37 mounted on a shell 23 which forms the enclosure for the cathode button 12 and its heater 13. The electrons emanating from the cathode 12 and under the influence of an accelerating potential provided by battery 69, accelerate toward a "smoother"  grid 35 and traverse the tube 57 after which they pass through gaps defined by grids 41 to 44 to be reflected back by the reflector electrode 57, the potential on which may be varied, for example by switch 76, to excite selectively one of the resonators. Energy is extracted from the resonators in the arrangement shown, by a wave-guide 79 the end of which is closed by a window 82 mounted in a frame 81 the configuration of which provides a relatively long heat path and minimises cracking of the window; alternatively energy may be extracted from the resonators by co-axial transmission lines (not shown). To ensure maximum output from the resonator 38 the length of the "drift" space 54 between the pairs of grids 41 to 44 is kept to a minimum. The arrangement is also such that the modes of oscillation of the resonators 38, 39, do not coincide or overlap. The use of laminations 46 to 50 facilitates the ready construction of resonators of different dimensions; if desired tuning mechanisms may also be employed in conjunction with the resonators. Selective operation may also be effected by altering the accelerating voltage as applied to the " smoother " grid 35 and the cathode voltage in addition to or alternatively to the reflector voltages. The apparatus may be used as a switching mechanism in which H.F. signals of different frequencies are generated in responses to pulses of different magnitudes.
