Title: Improvements in nut making and other machines
Inventor: KENDALL FREDERICK WILLIAM
IPC: B23G9/00
Filed: 1953-12-31
Abstract: 772,291. Lathe details. BROWN & WARD (TOOLS), Ltd. Dec. 22, 1954 [Dec. 31, 1953], No. 36283/53. Class 83 (3). An automatic nut-making &c. machine of the type in which a pivoted-arm picks up a work-piece from a position in which it has been machined and transfers it to another position for a further operation such as chamfering, comprises a transfer-arm which also forms a stop for the feed of a stock-bar automatically fed through the machine. The transfer-arm 1, Fig. 2, is secured to a shaft 2, which is rotated and moved axially in timed-relation with the other parts of the machine, by cam-mechanism. A notched-member 9 secured to the shaft 2 locates the latter, in conjunction with a spring- pressed plunger 14, Figs. 1 and 2, in an intermediate position, where it acts as a stock-stop for feed of the bar 4. Lateral movement of the transfer-arm brings an un-notched collar 13, Fig. 2, into line with the plunger so that the arm falls to its initial position, located by a stop 6, Fig. 1. In the latter position a spring-pressed stud 3 on the arm is aligned with a nut-blank 7 about to be parted from the stock 4. The transfer-arm is moved laterally to pick up the nut, and after rotating to the intermediate stock-stop position, it transfers the blank to a spring-pressed holder 17, Figs. 10 and 11, at a new station, where it is fed against a rotating chamfering-tool 15. A spring-blade 16, Fig. 10, ensures that the nut is turned into the correct position to enter the holder 17, where it fits behind prongs 19 until dislodged by the next nut-blank.

Title: Improvements in or relating to cathode ray tube processing apparatus
IPC: H01J9/22
Filed: 1965-08-25
Abstract: 1,094,720. Endless conveyers. RAULAND CORPORATION. Aug. 25, 1965 [Aug. 25, 1964], No. 36446/65. Heading B8A. [Also in Division H1] In a process for producing a pattern of dots of phosphor on the screen of a cathode-ray tube as a step in forming the screen with a pattern of phosphor dots producing red, green and blue radiations, the screens are conveyed on workholders through a closed path, one at least of the work stations being enclosed in a housing and subjected to a current of clean air. The screens are conveyed on work-holders on an indexing conveyer from a loading station, washed with detergent, rinsed, coated with polyvinyl alcohol, dried, coated with a slurry containing a phosphor material (e.g. green) and a photo-sensitive resist, dried and transferred manually to a second conveyer, a mask being placed above the screen and the screen exposed to light during its travel. It is then unloaded to a further conveyer on which it is washed to remove the unexposed parts of the coating, inspected, and further systems of phosphor dots (blue and red) applied similarly. To protect the screen from contamination during processing, all but the end stations of the conveyer are enclosed by walls and a stream of air is directed partially downwards around the path of the conveyer, being withdrawn at the bottom. In the apparatus described, two similar indexing conveyers are arranged side by side, with a single continuously moving rotary conveyer arranged adjacent one end of each. The indexing conveyers consist of two pairs of runways 41, 41a on which the screening carts are driven by a continuous chain. Each cart carries its own motor by which the workholders are rotated at appropriate speeds at different parts of their travel by means of buses running on power rails alongside each conveyer. The carts also engage tilt rails 50, 50a, 50b which determine the angle of tilt of the workholders at different parts of their travel. The tube caps 26 are carried by threearmed holders 73 on the carts, the holders 73 being exchanged when it is desired to operate on caps of different size and shape. Each cart carries also a screening mask 25 for use with the screen of that cart during the exposure period. Water jets for the washing steps are arranged at suitable points in the travel of the conveyers. The conveyers are enclosed in a housing 60 through which a stream of filtered air is directed downwards on to the work-holders escaping by a central exhaust duct.

Title: Improvements in and relating to pneumatic reversing gear of internal combustion engines
IPC: F01L13/02
Filed: 1938-12-15
Abstract: 506,153. Reversing. NAAMLOOZE VENNOOTSCHAP KROMHOUT MOTOREN FABRIEK D. GOEDKOOP Jr. Dec. 15, 1938, No. 36542. Convention date, Dec. 29, 1937. [Class 7 (v)] In a pneumatic reversing gear comprising a distributing member 13 supplying compressed air to a cylinder 19 whose piston 20 lifts the rollers 5 from the cam shaft 1, displaces the shaft axially and brings the rollers down again, the piston 20 during its outward stroke unlocks the cam shaft and lifts the rollers, at the end of the stroke opens a passage leading to a pipe 23 for the supply of compressed air for displacing the cam shaft and the member 13, and during its return stroke brings the rollers down again upon the cam shaft and locks the latter against displacement. As shown, the cam shaft 1 carries forward and reverse cams 3, 4 for actuating a roller 5 on the plunger of a fuel pump 6. Axial displacement of the cam shaft is effected from a pin 12 carried by the member 13 through arms 9, 11 on a shaft 10, which carries a hand wheel 40 to enable the axial displacement to be effected manually when necessary. The casing 14 of the member 13 is provided also with a slide valve 15 having rack teeth in engagement with a pinion 17 on a shaft 18 carrying a hand lever 38, Fig. 2, by which the valve is adjusted. The piston 20 also has rack teeth in engagement with a toothed sector 37 on a shaft 36, which carries a cam 35 in engagement with an arm 34 on a shaft 33 carrying a latch 32 for locking the cam shaft in its forward or reverse position ; the latch 32 co-operates with a projection 31 on the pin 12 of the distributing member 13. Another cam 41 on the shaft 36 actuates a lever 46. Fig. 3, for engagement with a part 49 of the fuel pump to lift the roller 5 from the cam shaft. The cam 41 also actuates a lever 42 connected to a rack 44 for reducing to zero the amount of fuel injected by the pump when the roller 5 is being lifted. In operation, when the valve 15 is moved to the " reverse " position shown in Fig. 1, compressed air from a pipe 25 is admitted through passages 25a, 28, 21a to the bottom of the cylinder 19 and raises the piston 20. A rod 52 within the piston is also raised to open a valve 53 for the escape of air from the upper end of the cylinder 19 through a passage 55. The upward movement of the piston releases the latch 32 and lifts the roller 5 from the cam 3. When the piston 20 uncovers a port leading to a pipe 23, compressed air is admitted through passages 23a, 27 to displace the member 13 and effect axial movement of the cam shaft; the compressed air is then supplied through passages 22a, 22 to the upper end of the cylinder 19 to reverse the movement of the piston 20, causing the roller 5 to be brought down upon the cam 4 and the latch 32 to re-engage the pin 12. In its lowest position, the piston 20 opens a port leading through a pipe 24 to a supply of compressed air for starting the engine astem.

Title: Improvements in or relating to agricultural machines
IPC: A01B69/00
Filed: 1969-07-22
Abstract: 1,271,957. Automatic steering mechanism. INTERNATIONAL HARVESTER CO. 22 July, 1969 [23 July, 1968], No. 36706/69. Heading B7H.  In an agricultural tractor/implement combination comprising a plough 12 drawn by a tractor 11 having front wheels 15 steered by power steering mechanism, there is provided automatic steering apparatus including forward and rearward sensing discs 30, 71 carried by the tractor 11 and plough 12 respectively and engageable with the wall of a furrow to guide the tractor and implement therealong, the forward disc 30 being arranged to actuate the power steering means to turn the front wheels 15 in response to deflection of the disc from a normal position relative to the wheels, and the rearward disc 71 being connected to the power steering mechanism so as to adjust the position of the front wheels 15 to compensate for lateral drifting of the plough when operating along a slope. Electric switches 43, 44 which control operation of the power steering mechanism are carried by mounting plates 41, 42 secured to a rotatable shaft 38 and are actuated by a cam secured to a sleeve 39 rotatable on the shaft 38. An arm 51 on the shaft 38 is linked by a rod 33 to a laterally displaceable arm 31 carrying the forward disc 30 so that deviation of the tractor 11 from the furrow causes rotation of the switch mounting plates 41, 42 relative to the cam to close the appropriate switch 43 or 44 and turn the front wheels 15 in the desired direction. An arm 52 secured to the sleeve 39 is linked through a rod 53, a lever 55, an arm 57 and a U-shaped link 59 to a plate 60 on the rotatable mounting of the front wheels 15 so that turning of the wheels rotates the switch actuating cam to obtain early opening of the switch 43 or 44 and avoid over-correction of the steered path. The lever 55 and the arm 57 are adjustably connected by the inner member 64 of a Bowden cable 61 actuated through a bell-crank 75 and a link 74 upon rotation of a vertical spindle 69 on which is mounted a spring-loaded arm 70 carrying the rearward disc 71. Lateral drifting of the plough 12 will thus cause displacement of the switch actuating cam to actuate the switches 43, 44 so that the power steering mechanism applies an appropriate correction to the position of the front wheel 15.

Title: Decarboxylation of unsaturated dicarboxylic acids and their derivatives
Inventor: BURNOP VICTOR CHARLES ERNEST
IPC: C08G61/04
Filed: 1959-11-03
Abstract: Maleic or fumaric acids, alkyl derivatives thereof, or maleic anhydride are decarboxylated by contacting with a tertiary amine to yield a polymeric product and/or acrylic or alkyl acrylic acids. Amines mentioned are dimethyl aniline, dioctylmethylamine or dimethyl (2-ethyl) hexylamine, pyridine, 2-vinyl and poly 2-vinyl pyridine and quinoline, and up to 15 mol. per cent is used.  Solvent such as esters, e.g. glycerol tri-acetate, dibutyl phthalate, dioctyl adipate and tricresyl phosphate, chloroform, ethers, acids and mineral oil solvents may be used.  Examples describe the preparation of polymers from maleic anhydride by heating in the presence of pyridine, poly-2-vinyl pyridine; from fumaric acid with dioctyl methyl amine; and from monomethyl maleate with pyridine and quinoline.  The polymeric products may be further cross-linked by heating with, or including in the original mixture organic compounds containing two or more polar groups for example diamines, glycols and amine alcohols, aromatic diamines and dihydroxy compounds, urea, guanidine and melamine. Examples describe the cross-linking of a maleic anhydride polymer with ethylene glycol and ethylene diamine, and the formation of resins by heating maleic anhydride with ethylene glycol or ethylene diamine with pyridine and with hexamethylene tetramine. The resinous products may be used as adhesives or may be heated with for example n-dodecylamine to form a further resin.ALSO:Acrylic and alkylacrylic acids are prepared by heating maleic or fumaric acid or an alkyl derivative thereof or maleic anhydride, in the presence of a tertiary amine such as dimethyl aniline, dioctyl methylamine or dimethyl (2-ethyl) hexylamine, pyridine, 2-vinyl pyridine, poly-2-vinyl pyridine and quinoline. The compounds are decarboxylated and the reaction may take place in solvents such as glycerol triacetate, dibutyl phthalate, dioctyl and dicresyl adipates, dicresyl phosphate, chloroform, ethers, acids and mineral oil solvents.  In examples monomethyl maleate was heated with quinoline or pyridine and methyl acrylate was distilled off; fumaric acid heated with quinoline at between 180 and 260 DEG C. produced acrylic acid which was distilled off.  The process may be continuous. Polymeric products are also produced by the process.
