Title: Improvements in or relating to milling machines
IPC: B23Q35/10
Filed: 1960-04-19
Abstract: 903,738. Milling-machines. DE VLIEG, H. R. April 19, 1960, No. 13582/60. Class 83 (3). A machine-tool comprises a rotatable member 653, Fig. 3, slidingly supported on bars 254 in a housing 233, and carrying a cam 460 engaging a follower 440 fixed in the housing, and a workholder 150, Fig. 8, and a rotatable tool-carrying spindle 40, Fig. 4, reciprocable axially to and from the work-holder. Spindle 40 is mounted in a quill 70, driven via belt 53 from electric motor 28, adjustable angularly by rotating the spindle housing 17 in the support 15 therefore, and axial movement is limited by a collar 58 and effected by rotating a pinion 109 meshing with rack teeth on the quill. Member 653 is urged by spring 262 to press the cam against the follower which is adjustable by screw 450, and the member rotated in a housing 404 slidingly engaging the bars by electric motor 647 through a reduction gear 600 and pinions 424, 424A, 413. Workpiece A is clamped between discs 172, 173 on a spindle 163 indexable in the work-holder body which engages the member 653 with its slot 151. The spindle carries a pinion 181 engageable by a locking rack 223, Fig. 9, and one-way clutch 190 driven by a pinion 191 rotatable by a rack 192. In use, switch 756, Fig. 17, is closed to start motor 647 and rotate the member 653 which actuates a switch 475 selecting slow speed for motor 647 and energizing solenoid 763. This actuates valve 750 admitting compressed air from inlet 752 to conduits 764, 765, 766, thus lowering the quill and locking it with plunger 97, the solenoid remaining energized by a holding relay 774. The member 653 turns and the work is machined until arm 480 actuates switch 475 which causes relay 760 to speed up motor 647, relay 774 to de-energize solenoid 763, solenoids 773 and 780 to be energized. Thus the quill is raised and compressed air is supplied to a chamber 218 to move a piston 219 and release locking rack 223. The air then passes via parts 512 to move rack 192 which indexes the work. Solenoid 780 is de-energized by time switch 778 to exhaust the air in line 781, thus restoring rack 192 and the locking rack 223, while relay 774 maintains solenoid 773 energized. Then when the member 653 actuates switch 476, the cycle recommences. Switches 143 and 503 prevent indexing and commencement of the cycle respectively if the tool spindle is not withdrawn and if the work is incorrectly indexed.
Patent GB-407558-A (GB)
Title: Improvements in and relating to pivoted joints
IPC: E05D11/00
Filed: 1933-05-10
Abstract: 407,558. Hinges; tables. WILSON, E. L., 94, Demesne Road, Wallington, Surrey, and WELLS, E. G., Temple Wood, South Park, Gerrards Cross, Buckinghamshire. May 10, 1933, No. 13649. [Class 65 (ii).] In a pivoted joint, particularly for attaching the leg to the top of a folding table, one member carries an axially-movable spring-influenced plunger or detent, while the other member has two or more spaced apertures, depressions or protuberances for engagement by the plunger, at least one of the apertures or their equivalent being such as to permit locking engagement of the plunger while with the remaining one or ones the plunger has only frictional or resilient engagement ; the leg is thus rigidly locked in one position until the plunger is released by hand, but it can be moved from other positions by reasonable force, the plunger yielding to permit the movement. In the form shown, a table leg 4 is mounted on a pin 3 which is supported in a U-shaped bracket 2 fixed to the frame 1 of the table top ; the top of the leg is provided with a pair of plates 5 with apertures to guide a plunger 10 which is pressed against the bracket 2 by a spring. The bracket is provided with a hole which the plunger can enter in the position shown, to lock the leg against movement until the plunger is withdrawn by the cam lever 13, and an aperture of smaller diameter for partial engagement by the nose of the plunger when the leg is folded, to hold the leg in that position against light pressure or its own weight ; the smaller aperture may be slightly elongated to allow some freedom in the folded position of the leg. The bracket 2 may be modified to allow the leg to fold diagonally across the table top. A small shelf 15 is pivoted to the table leg by a pin 18, and has a similar locking plunger 23, the plate 19 with which the plunger engages having in this case two resilient holding apertures, to allow the shelf to be held folded up or down, as well as a central locking hole. Any or all of the apertures may be countersunk to assist the engagement of the plunger. The apertures may be replaced by depressions or projections for engagement with a plunger of suitable form. In applications, such as to the supporting framework of a sun-blind, where a member is supported by two joints, one of these joints may be provided with means for positive locking in various positions while the other is arranged for resilient holding in these positions, so that the member does not move of itself when the locking means is released.
Patent GB-1577375-A (GB)
Title: Process and apparatus for applying ferromagnetic toner to a substrate
IPC: G03G19/00
Filed: 1977-03-31
Abstract: In the magnetographic process for reproducing graphic information, a magnetic image is formed in a premagnetised layer consisting of acicular chromium dioxide by selective heating of the latter to a temperature above its Curie point. Subsequently, ferromagnetic toner particles are uniformly applied to the chromium dioxide layer, so that they adhere only to the magnetised areas. The toner particles are electrostatically transferred to a substrate and fused on in their position. Alternating-current corona discharge devices or other static neutralisation devices are used for neutralising undesired charges on the toner particles, which would otherwise cause blurred images and undesired background markings on the finished copies.

IPC: F02M41/14
Filed: 1961-04-17
Abstract: 1,006,075. Fuel injection pumps. C.A.V. Ltd. April 4, 1962 [April 17, 1961], No. 13693/61. Heading F1A. A vane type pump 2 feeds fuel to three inlet ports 17, 18, 19 to a rotary valve 9. The port 17 communicates in turn with passages 11 leading to a pump chamber 5, a port 28 always communicates with one passage 11 and is connected to the topside of a shuttle 24 which is axially and angularly adjustable by a plug 22, connected to a governor arm 23 and a piston 36 subjected to feed pressure from the port 19. The port 18 communicates in turn with passages 12, one of which communicates with a port 29 connected to the under side of the shuttle 24. The passages 12 also communicate through a passage 14 which communicates in turn with outlet pipes 15. With ports 17, 18 open to passages 11, 12 fuel forces pistons 6 outwardly and raises the shuttle 24. The ports 17, 18 close and the pistons 6 discharge fuel to the port 28 which forces the shuttle down so that fuel is spilled back to inlet through the pressurising valve 31 until the control edge 32 closes the port 30, thereafter fuel is discharged by the shuttle 24 to an outlet pipe 15 until the control edge 33 uncovers the port 30. Angular and axial adjustment of the shuttle 24 adjusts the timing of the commencement and ending of injection. The end face of the shuttle 24 may be used to control the port 30 instead of one or other edge 32, 33. In a modification the arm 23 is replaced by a pinion on the plug 22 which meshes with a rack subjected at one end to fuel feed pressure and at the other to spring pressure varied by a throttle actuated lever. In an alternative construction the shuttle 24 is housed in an axial passage in the distributer 9. The valve 31 may be replaced by a non-return valve incorporated in the passage 13.

Title: The manufacture of oxycarboxy-ºÔ-diamine-diaryl-sulphones and of oxycarboxy-ºÔ-amino-oxy-diarylsulphones
Filed: 1926-06-07
Abstract: 267,366. Carpmael, W., (I. G. Farbenindustrie-Akt -Ges.). June 7, 1926. Diarylsulphones.-o-Oxycarboxy-p-diamino (or p-amino-oxy)-diarylsulphones and their substitution products are made by condensing an o-oxycarboxyaryl-sulphinic acid with a p-quinone-di (or mono)-imide, or with a substitution product thereof. The quinone-imides are obtained by oxidation of p-diamines or their substitution products or N-alkyl derivatives, or of p-aminophenols, or their substitution products, and the oxidation and condensation processes may be effected in one operation. In examples, (1) a mixture of 4-oxy-3-carboxybenzene sulphinic acid and p-phenylenediamine is treated with ferric chloride to yield 2: 5-diamino-4<1>-oxydiphenylsulphone-3<1>-carboxylie acid; the 4-methoxy cr ethoxy derivativeis obtained by using 2 : 5-di aminoanisol or 2: 5-diaminophenetol instead of p-phenylenediamine, and 2-amino-5-dimethylamino - 5<1> - methyl-4<1>-oxy-diphenylsulphone-3<1>- carboxylic acid is obtained from the corresponding cresotinic sulphinic acid and 4-aminodimethylaniline, (2) 4<1>-5-dioxy-3<1>-carboxy-2-aminodiphenylsulphone is obtained from p-aminophenol and 4-oxy-3-carboxybenzene sulphinic acid, and (3) 3 : 4<1>-dioxy-2-amino-4: 5<1>-dimethyl-diphenylsulphone-3<1>-carboxylic acid is obtained from 5- amino-2-oxytoluene and cresotinic sulphinic acid. The sulphone group takes up the o-position to an amino group, and the remaining amino group in the case of the diamines can be acylated by treatment with acetic anhydride, benzoyl chloride, pmethoxybenzoyl chloride, phthalic anhydride, toluene sulphochloride, salicyl sulphochloride, chlorcarbonic esters, phosgene and the like. o-Oxycarboxyarylsulphinic acids are obtained by gentle reduction of the corresponding sulphochlorides. or by decomposing the diazo compounds of the o-oxycarboxylic acids with sulphur dioxide in the presence of copper. 2 : 5-Diaminoanisol and 2 : 5-diaminophenetol are obtained by reducing 5-nitro-2-aminoanisol or the corresponding phenetol with stannous chloride and hydrochloric acid. Azo dyes.-The above-described diarylsulphones may be used as components in the manufacture of azo dyestuffs, particularly for dyeing wool by chroming processes or for chrome-printing on cotton. The diazo-compound obtained from 4<1> : 5-dioxy-3<1>-carboxy-2-aminodiphenylsulphone gives a red dyestuff when coupled with R salt, and a yellow dyestuff with resorcin; diazotized 3 : 4<1>-dioxy - 2 - amino-4 : 5<1>-dimethyl-diphenylsulphone-3<1>-carboxylic acid also gives a yellow dyestuff with resorcin. Indophenols and indamines.-The above-described diarylsulpbones may also be used for the manufacture of indamines and indophenols,

Title: Process for making cold-flowing material for bituminous road surfacing which hardensafter being applied
IPC: C08J3/09
Filed: 1931-05-14
Abstract: Cold flowing material for road surfacing which hardens after being applied is prepared by dissolving tar pitch or asphalt separately or in mixture in a solvent composed of light volatile, heavy volatile, and chloro hydrocarbons.  A feature of the invention is that a homogeneous mixture of the materials is obtained using the above solvent mixture which does not form a deposit on standing, such mixture being preferably obtained by dissolving tar and pitch in the solvent mixture and then adding asphalt dissolved either in the chloro-hydrocarbon alone or in the complete solvent mixture, and subjecting the whole to agitation in a turbo mixer.  The starting materials may be subjected to an oxidizing, sulphurating, or polymerizing treatment before being dissolved in the solvents.  In some cases the mixture of the base materials is formed immediately before the solutions are to be applied to the road when deposits could not otherwise be prevented with the materials available.  The exact proportion of solvents used in each case is best determined by experiment, thus the solvent capacity of the heavy volatile hydrocarbons for pitch can be regulated by changing the anthracene oil percentage.  The preferred proportion of light volatile solvents (b.p. up to 150 DEG  C.) to heavy volatile solvents (b.p. over 150 DEG  C.) is 4 : 3, and the preferred proportion of solvents to solid matter is 35 : 65. In an example 6,3 kgs. of tar at 50 DEG  C. are placed together with 1 kg. of a mixture of 40 per cent crude benzol first running, 30 per cent of crude benzol, and 30 per cent solvent naphtha, in an autoclave provided with a stirrer and reflux apparatus.  2,2 kgs. of pitch are added and mixed at 90 DEG  C. After cooling to 75 DEG  C. 0,5 kgs. of trichlorethylene are added, to produce a cold flowing tar-pitch solution.  A cold flowing solution of 6,67 kgs. of asphalt in 3,33 kgs. of trichlorethylene is prepared in a similar way and finally 8,5 kgs. of tar-pitch solution are homogenized with 1,5 kgs. of asphalt solution in a turbo mixer.

Title: Improvements relating to liquid dispensing apparatus
Inventor: MONK PHILIP REGINALD
IPC: G01F11/32
Filed: 1957-05-06
Abstract: 895,039. Delivering measured quantities of liquids. BAIRD & TATLOCK (LONDON) Ltd. May 6, 1958 [May 6, 1957], No. 14415/57. Class 106(5). A liquid-dispensing apparatus capable of dispensing accurately predetermined quantities successively into a plurality of containers consists of at least one unit comprising a liquidmeasuring chamber 16, Fig. 2, communicating, through passages in a valve block 2, with inlet and outlet valves 12 and 13 mounted on faces 6, 7 of the block 2 with an inlet 9 connecting the face 6 to a reservoir of liquid under pressure and an outlet 11 connected to the face 7 through which the predetermined quantity is expelled from the chamber 16 in which measuring is effected, e.g. by the rise of a piston 18. An apertured cup-shaped support 14 holds the lower end of the chamber 16 when it is made of glass, but the support is formed integrally if the chamber is of metal; it is secured in a recess 3 in the valve block 2, the recess communicating with a passage 4 which leads into a transverse passage 5 between valve-controlled ports in the faces 6 and 7 of the block. The valves may be electromagnetically operated, of the type described in Specification 853,469, or they may be pneumatically or mechanically operated. When the predetermined quantity of liquid has passed into the chamber 16, the inlet valve 12 is de-energized and discharge may be effected at any subsequent time by energizing the outlet valve 13. Three similar dispensing units are shown mounted on a casing 21 which carries sets of guide wheels 22 and locating means 23 for a test-tube rack 24, Fig. 3, which comprises a metal frame 25 and a cover-plate 26 having three rows of test-tube-receiving holes spaced apart by distances equal to the spacing between the dispensing units. Guide strips 31 engage the guide wheels 22 and a further guide strip 32 is notched opposite each series of three test tube apertures 27, 28, 29 for engagement with rollers 34 and locating means 23. The upper end of each piston 18 may be arranged to close an adjustable contact 36 on a block 37 slidable on a guide rod 38. A switch included in the locating means 23 energizes the inlet valves 12 to allow liquid to flow from the reservoir until the ends 35 of the pistons 18 close the contacts 36 to effect closure of the inlet valves and the opening of the outlet valves 13. A pilot light 39 is connected in the outlet valve circuit to indicate the completion of a cycle of operations. A sealing collar may be provided in a recess in the top of the measuring chamber to reduce leakage; liquid may be supplied to this recess to prevent crystallisation of the thin film of liquid between the cylinder and piston. The Provisional Specification describes also the test-tube rack 24 as movable automatically through the apparatus.
