Title: Ball joint
IPC: F16C23/04
Filed: 1959-10-16
Abstract: 910,690. Ball and socket joints. KLOCKNER - HUMBOLDT - DEUTZ A.G. Oct. 16, 1959 [Oct. 17, 1958], No. 35123/59. Class 65 (2). [Also in Group XXII] In making a ball joint, particularly for connecting the lifting linkage of an agricultural tractor to the fitted implements guided thereon, two annular part-sockets 6, 7 having cylindrical external surfaces are pressed inwardly from both sides over an inner ball 4 into a cylindrical bore 2 in the linkage component 1 so that the chamfered mutually abutting edges of the part-sockets are bent over outwardly into an annular groove 3 formed substantially centrally of the length of the bore. After the pressing operation the outwardly bent edges substantially fill the groove and the outer end faces of the part-sockets are level with the shoulders of the ball which consequently serve as abutments for the pressing tool. The part-sockets may be made of steel and their part-spherical inner surfaces may be hardened.

Abstract: 1311073 Feeding sheets MILLER PRINTING MACHINERY CO 27 July 1971 [30 July 1970] 35216/71 Heading B8R Sheets are fed from a pile 10, Fig. 1, and over an inclined feed table 12, Figs. 1 and 2, to abut against front stops 14, Fig. 1, 2 and 4, on a shaft 28 which also carries feed rollers 18 projecting through slots in the table to engage upper rollers 16. As an impression or other cylinder 20 of a printing-machine rotates, a cam 72 alternately moves a lever 74 clockwise about an eccentric bushing 76 so as to rotate the shaft 28 counterclockwise by means of a flexible band 88 and allows the lever to move counterclockwise so that a spring 100 rotates the shaft 28 clockwise by means of a flexible band 94. The rollers 16 are pivoted on a shaft 146 for movement towards and away from the rollers 18. Counterclockwise rotation of the shaft 28 moves the stops 14 out of the sheet path and advances a sheet at a speed greater than that of the cylinder 20 so as to buckle it against a register bar on the cylinder, grippers 22 on which then close to grip the sheet and carry it into the machine. Clockwise rotation of the shaft 28 brings the stops into position to register the next sheet, which is also registered sideways before feeding to the grippers. The stops are adjustable angularly by adjusting the shaft 28 with respect to a member 40 securing the bands. The tension of the spring 100 is adjustable by nuts 108, 110. A hand wheel 118 is rotated to adjust the position of the bush 76 and thus the pivotal axis of the lever 74 and its degree of movement by the cam, so as to adjust the degree of buckling according to sheet thickness. Bolts 136 adjust the stops individually to conform to straight or curved front edges of the sheets, or to move some out of operative position.

Title: Separation of benzine polycarboxylic acids
IPC: C07C51/573
Filed: 1958-11-18
Abstract: A process for resolving a mixture comprising unsubstituted p  benzene polycarboxylic acids, at least one but not all of which is capable of forming an intramolecular anhydride, comprises heating the mixture to dehydrate the benzene polycarboxylic acid capable of forming the intramolecular anhydride, extracting the anhydride from the mixture with an aromatic hydrocarbon solvent at a temperature of from 20-200 DEG C. and recovering the extracted benzene polycarboxylic acid anhydride.  The acid mixture containing the intramolecular anhydride-forming acids, i.e. having two carbonyl groups in the ortho configuration, may be obtained by any of the known methods, e.g. nitric acid or air oxidation of alkyl benzenes.  The aromatic solvent used may be toluene, xylene or preferably a mixture of alkyl-substituted aromatic compounds oxidisable to a mixture of benzene polycarboxylic acids.  The anhydride may be recovered by evaporation of the solvent or by cooling the solvent and crystallising the anhydride.  Benzoic acid, if present in the mixture of polycarboxylic acids, may be removed by first extracting the mixture with an aromatic hydrocarbon at a temperature below the dehydration temperature. An aromatic hydrocarbon may be added to the heated mixture to assist in water-removal during the anhydride formation, e.g. cymene for dehydration of o-phthalic acid or durene or prehnitene for dehydration of trimellitic acid.  A lower boiling hydrocarbon may be used however, and when an excess is used anhydride formation and extraction into the hydrocarbon may be conducted simultaneously.  In Examples (1) a mixture obtained by air oxidation of a C8 aromatic fraction boiling at 136-45 DEG C. is resolved by extracting with toluene at 25 DEG C. to remove benzoic acid, heating the residue with approximately 6 1/2 % of xylene at 178-85 DEG C. to dehydrate o-phthalic acid, extracting the cooled mass with toluene at 85 DEG C. and recovering a mixture of isophthalic and terephthalic acids as a residue and phthalic anhydride by evaporation of the toluene filtrate; (2) a 1:2 mixture of trimesic and trimellitic acid is boiled with acetic anhydride and xylene at 178-85 DEG C. the mixture filtered at its boiling point and trimesic acid recovered as a residue and trimellitic anhydride recovered from the filtrate.

In a script display system a switching system is incorporated so that when a speaker is delivering the material set out on the display, accompaniments-such as the switching on or off of lights, starting or stopping of music, film projectors or the like-may be arranged to take place at will. Such a switching system comprises a number of relays 41 each controlled by a gas-filled valve 8, the contacts of each relay and the grid of each valve being connected to jacks in a section 43 of a panel 4. A number of output connectors 12 are provided together with a similar number of output control switches 14, the terminals of each of which connectors and switches are also connected to jacks in a section 47 of the panel 4. The panel 4 is also provided with a number of earthed jacks GR and a number of jacks P1, P2 which are connected to the supply indicated by a lead 16. In operation the apparatus forming the accompanimentshown in Fig. 6 as a spotlight 60-is connected to an output connector 12 and jumper leads 62, 64, 66 are arranged between jacks F, P2; C1, P1; and N01, A respectively. Closure of switch 5 energizes the circuit and after a time delay valve 10 has operated H.T. is applied to the valve 8. This valve does not conduct since it is biased off by means of a rectifier 48 and condenser 50. As the script display progresses a conductive strip thereon, represented by contact 381, is arranged to earth the grid of the valve so allowing it to conduct and energize the relay 41 thereby causing the light 60 to be lit. A circuit for maintaining the grid of the valve 8 earthed when the display has moved on is formed by jumper leads 68, 70, 72 between jacks G, N02; C2 to jack Cl of a second relay and jack NC1 of this second relay to an earthed jack GR respectively. The first valve 8 is maintained conductive until a second conductive strip on the display arrives to earth the grid of the second valve to render it conductive and energize the second relay thus causing the light 60 to be extinguished. The switch 14 is provided to enable alternative automatic or manual operation to be had and jacks C-, C+ are provided to allow capacitance to be inserted to give a time delay to the relay. Lamp 17 is an indicating lamp and push 15 is a disenabling switch. Jacks T are provided for use as desired. Specification 710,385, [Group XXXVII], is referred to.
