Title: Crossed axes gear rolling
IPC: B21H5/02
Filed: 1971-07-15
Abstract: 1323205 Rolling gears LEAR SIEGLER Inc 15 July 1971 [17 Aug 1970] 33207/71 Heading B3M A workpiece spur gear is rolled by one or more gear-like dies having helical teeth with a helix angle of between 3 and 15 degrees. Two dies 18 and 22 (Fig. 1) may contact opposite sides of a workpiece W, the dies being rotated in synchronism by a common motor and being mounted on respective rotatably adjustable supports 20 and 24. The workpiece is supported by a shaft 54 and columns 56, 58 on a table 64. The support 24 may be coupled by a linkage 78, 84 to the table 64 such that any vertical movement of the support 28 (and hence the die 22) is converted into half that movement of the workpiece W. To prevent the spur teeth on the workpiece from being non-uniform along their length, due to the relative inclination of the die and workpiece axes, the teeth on the dies may be longitudinally concave. Alternatively, the workpiece may be traversed in a horizontal plane during rolling. The dies may have modified teeth shapes in order to produce slightly crowned or convex teeth on a workpiece. So that the axial forces generated on the workpiece 100 (Fig. 4) by the dies 102 and 104 cancel each other out, the helix angles of the dies can be respectively right and left-hand.

Title: "spraying apparatus suitable for decorating articles of earthenware, pottery or chinaware or similar workpieces"
Inventor: FOURNIER ALBERT
IPC: B05B12/22
Filed: 1956-11-02
Abstract: A machine for decorating e.g. banding dishes and similar articles 2 comprises a device, e.g. a pair of driven rollers 3, for supporting and rotating the dish, a spray gun 24 directed towards the rollers 3, a plate 41 on a carrier, e.g. a bar 48 adjustably mounted on a pillar 38, which is movable so that the plate 41 can approach the dish 2 in the path of the spray and be retracted from the dish 2, means for moving the carrier 48, 38, and means for supplying compressed air to the gun 24 when the plate 41 is near the dish 2, the means acting in synchronism with the rotation of the dish 2 whereby the dish completes at least one revolution while the gun 24 is operated and the plate 41 is in operative position.  A mask 126 is adjustably bolted at 127 to the plate 41 with the outer edge of the mask 126 more to the edge of the plate 41 to provide a space down which liquid droplets may flow to ensure a sharp edge to the coloured band on the dish 2. The gun 24 is adjustably mounted on the pillar 38 which is movable horizontally in a slot in a table 1 which supports the entire apparatus, including an inclined plate 9 which has spindles, as 8, 6 respectively, for a platen 5 for the dish 2 and for the rollers 3.  A motor <PICT:0841838/III/1> <PICT:0841838/III/2> 21 drives a pulley 17 on a shaft 16 which carries a pulley 15 and a belt 14 for driving the rollers 3, which may be rubber-covered, and a worm 103 engaging a gear wheel 102.  A cam track 99 in the wheel 102 controls the operation of the apparatus as follows:-During part of the rotation of the wheel 102 a ball 98 on an arm 97 falls into a gap in the track 99 to actuate a mercury switch 93 and so to energize a coil 88, Fig. 11, in a valve 77 which thus passes compressed air through a line 86 to a cylinder 56 to move a piston rod 52 against a spring 66 to the right. The pillar 38 is secured to the rod 52 by a collar 51 and is hence moved to carry the gun 24 and plate 41 clear of the dish 2. Movement of the collar 51 allows a spring-pressed arm 114, Fig. 11, to pivot and permit a valve 106 in an air line 105, 107 to close and to cut off compressed air to an inlet 28 on the gun 24, which thus ceases spraying.  When the track 99 engages the ball 102, the valve 77 is closed, the spring 66 advances the carrier 38, 48 to the left, air going to atmosphere at 81, and the collar 51 engages the arm 114 to open the valve 106 and actuate the gun 24.  A ball 121 on the bar 48 engages a cup formed in a hub 122 on the plate 41 which carries a trough 133, for recovering liquid spray material, and the adjustable mask 126 spaced by washers 128 from the plate 41.  Air is supplied by a line 136, Fig. 11, to a pipe 131 leading to a space between a plate 132 and the back of the plate 41 where the air forms a thin screen to improve the decoration of the dish 2.  A further air line 137, Fig. 11, delivers air to a liquid supply tank 27 which communicates at 26 with the gun 24.

Filed: 1965-08-05
Abstract: 1,093,009. Stamping; stretch-forming. JOSEPH LUCAS (INDUSTRIES) Ltd. July 11, 1966 [Aug. 5, 1965], No. 33619/65. Headings B3E, B3Q and B3V. A method of deep drawing or stretch forming steel sheet comprises heating a blank to a temperature at which its structure changes from martensitic to austenitic, inserting the blank between tools which have been heated to a temperature above the temperature at which the austenitic structure of the sheet will change to martensitic, and actuating the tools to perform the required deep drawing or stretch forming operation. In an example, a maraging steel of 18% Ni, with the remainder of substantially pure Fe, is heated to 850‹ C. in an argon atmosphere, the temperature being maintained for 15 minutes to change the structure from martensitic to austenitic. The blank is then deep drawn between drawing tools heated to 170-260‹ C., using colloidal graphite as a lubricant.

Title: Improvements in or relating to distillation plants for aqueous liquid
IPC: C01C1/10
Filed: 1953-12-03
Abstract: <PICT:0778066/III/1> In a plant for distilling aqueous liquors, such as ammoniacal liquor, comprising a fractionating column, the hot effluent discharged from the bottom of the column is passed to a closed chamber which is connected to a suction pump whereby part of the mixture is flashed into steam, and means are provided for feeding a proportion of the liquor-to-be-distilled into the chamber and for delivering, by means of the pump, the mixture of steam and vapours released in the chamber into the column.  Ammoniacal liquor is supplied through pipe 11 into the upper part of column 10 which is heated by steam introduced through pipe 29.  The distillate is withdrawn through conduit 13.  The effluent discharged from the base of the column flows via float-valve 17 and pipe 16 into chamber 15, the lower part of which is divided into two sections by baffle-plate 22.  A pipe 24 joins the top of the chamber to the throat 26 of a venturi, which receives fresh steam through pipe 27.  A branch pipe 32 from pipe 11 is connected through valve 33 and flow-indicator 34 with spray-pipe 35 arranged within chamber 15 above packing material 30 which is supported on perforated plate 31.  The ammoniacal liquor introduced through pipe 32 is distilled as it flows over the packing by the steam evolved from the hot effluent in the lower part of the chamber. The steam and ammonia withdrawn from the chamber via pipe 24 are introduced, together with the fresh steam from pipe 27, into column 10 through pipe 29.  Effluent is discharged from chamber 15 by means of pipe 19 which is on the opposite side of baffle 22 to pipe 16.  Pipes 16 and 19 are joined by a bypass 20 controlled by valve 21.

Title: Delay line memory
IPC: F15C1/12
Filed: 1961-09-20
Abstract: 940,172. Calculating apparatus. SPERRY RAND CORPORATION. Sept. 20, 1961 [Sept. 26, 1960], No. 33732/61. Heading G4B. A fluid operated storage device comprises a fluid amplifier and fluid delay means (serving as a data store) responsive to output signals from the amplifier and adaptedto apply output signals to an input of the amplifier. A fluid compressor 11 supplies a power jet via a pressure regulator 9 and duct 7 to power jet inputs 1A, 3A, 5A of three fluid amplifiers 1, 3, 5 of known type, from which the power stream normally flows through output ducts 1C, 3C, 5C back to the compressor. Pulses, representing binary "ones", arriving at control inputs B of the amplifiers, deflect the power stream to a corresponding output D and the input B of the next amplifier. The apparatus described is designed to store a 4-bit word, a delay line 15 being connected between the output 3D and input 1B so that pulses take four times longer to travel around the delay line 15 than between input 1B and output 3D. Binary "ones" are entered by a control pulse on an "overriding" input 1E which deflects the power stream into duct 1D irrespective of any regenerating input pulses at 1B. Similarly, input pulses at IF direct the power stream into duct 1C, irrespective of the pulses at 1B, so that the pressure at the output 1D is relatively low indicating a binary zero. A tap 17 is provided at the beginning of the delay line 15 for serial readout or in a modification (Fig. 2 - not shown) several taps are spaced at appropriate distances around the delay line to enable parallel reading out of the stored information. When read-out is required suppressing pulses to an "overriding" input 5E are stopped, allowing pulses from the input 5B to direct the power stream to the output 5D.
