Title: Resettable electric switch
IPC: H01H9/26
Filed: 1973-05-21
Abstract: 1399577 Scoring apparatus AMP INC 21 May 1973 [13 June 1972] 24032/73 Heading A6D [Also in Divisions G4 and H1] A thumbwheel operated switch module, Fig. 5, having a common reset mechanism for a row of such modules, Fig. 2, is used for transmitting scores to a display unit (Fig. 1, not shown). A cup-shaped number wheel 34 which carries a contact brush 42 for selective engagement with fixed contacts 30 on a printed circuit board 26 is rotated by means of the thumbwheel 70 through a spring biased disconnectable clutch unit 58 and slidable splines 62 on a stem 60 passing through a bearing sleeve 50 of a cover unit 48 which in turn serves to provide an annular recess 46 for housing the number wheel on its one side and an annular pocket 52 for housing the clutch spring 54 on its other side. The thumbwheel 70 is detented for location of its position by a spring 99. Each switch module is contained within a housing 82 and a reset shaft 72, independently movable both axially and rotationally within a central aperture in the various elements, has key and socket ends 74, 76 for mating with adjacent shafts and a thrust collar 84 carrying a tooth 104 which is engageable during shaft rotation with a cooperating tooth 64 on the face of the clutch plate. The reset mechanism, Figs. 3 and 4, operates on a coupled row of reset shafts, and causes the thrust collars 84 to disengage each clutch plate from its associated thumbwheel during axial motion with the consequential resetting to zero of each number wheel independently of the position of its thumbwheel during rotational movement. For the axial movement a lever 138 is operated by knob 152 being moved to the left in L- shaped slot 124 and thus pushing it against pinion 116 which is mated within a socket end 76 as well as bringing a rack 142 into engagement with the pinion. For the rotational movement the rack is moved transversely to the pinion by pressing the lever downwards and on release a return spring 148 initiates reverse rotation of the pinion whereupon the shafts restore their respective reset teeth 104 to their original position. On final movement of the lever to the right all clutch plates are re-engaged with their thumbwheels. . An alternative embodiment (Fig. 12-16 not shown) incorporates a bevel gear drive to the clutch plate from a serrated thumbwheel of larger effective diameter and with a different locating spring arrangement.

Filed: 1955-08-22
Abstract: 793,719. Road-vehicle spring-suspensions. METALASTIK, Ltd. July 25, 1956 [Aug. 22, 1955], No. 24166/55. Classes 108(2) and 108(3) A rubber spring 9 is loaded in combined shear and compression between a vehicle frame 30, and a wheel-carrying structure 8 connected to the frame 30 by a central pivot 18, movement of which is accommodated by deformation of rubber 38, the spring 9 being pre-compressed on assembly, and the spring compression being apapplied to a trailer vehicle, the frame 30 is a turntable platform and is rigid with arms 31 which support brackets 32 which at their forward end carry a pivot pin 36 for the connection 18. The brackets 32 are rigid with respective diagonally extending struts 22. The other end of each strut 22 is rigid with an abutment33 for one end of the respective spring 9. This abutment is also rigid with the frame 30. The other end of each spring 9 is in abutment with the structure 8 which as shown comprises an axle for the road wheels 20. The structure 8 is connected by a pair of diagonally extending ties 17, 17 and a central tie 23 to a block 35 formed with a cylindrical aperture to receive three peripherally-disposed parts 39, each of which has a part-cylindrical surface adapted to engage the aforesaid aperture. The inner surfaces of the members 39 form a sperical surface which engages a layer of rubber 38 to compress it around a spherical element 37 rigid with the pin 36. The pre-compression of the spring 9 is thus withstood by the joint 18. In a modification (Fig. 1), the ends of the struts 22 remote from the springs 9, are rigid with a part-spherical member 24 by a layerof rubber 26 which is bonded to the members 24, 25. The member 24 is rigid with the ties 17, and the tie 23. A turnbuckle may be disposed in each of the ties of the struts 22 in order to enable their lengths to be varied.

Patent GB-689095-A (GB)
Title: Manufacture of 2:4:4-trimethyl pentanal
IPC: C07C45/58
Filed: 1949-09-21
Abstract: 2,4,4-Trimethyl-pentanal is obtained by the isomerization of 1 : 2-epoxy-2 : 4 : 4-trimethylpentane by bringing the latter into intimate contact with a strong acid to form a two-phase mixture, said acid having a volume/volume concentration in the acid phase of between 25 and 100 per cent, while maintaining the temperature in the reaction mixture at below 40 DEG  C.  Specified acids are aqueous sulphuric acid, phosphoric acid, and para-toluene sulphonic acid.  An organic solvent for the epoxide may be present provided it does not dissolve the aqueous acid and is not attacked thereby.  Specified solvents are hydrocarbons, e.g. paraffins, olefines, aromatic hydrocarbons, naphthenes; halogenated hydrocarbons such as chloroform and carbon tetrachloride, and liquid ethers.  The acid may be suspended in the solvent and the epoxide added, or the acid may be added to the solution of the epoxide in the solvent.  Alternatively a solution of the epoxide may be added to the agitated mixture of acid and solvent or a mixture of the acid and solvent added to the epoxide solution. The process may be carried out batchwise or in a continuous manner and instead of using purified or concentrated epoxytrimethyl pentane the crude oxidate resulting from the oxidation of di-isobutene in the liquid phase by means of free oxygen containing gases, as described in Specification 682,067, may be used.  In examples, the isomerization is effected by: (1) adding a benzene solution of a fraction containing 90 per cent of the epoxide to 50 per cent volume/volume aqueous sulphuric acid, the mixture being maintained at 30 DEG  C. by cooling; (2) mixing a solution of the epoxide in cyclohexane with 100 per cent phosphoric acid; (3) adding dry powdered p-toluene sulphonic acid to a solution of the epoxide in cyclohexane; (4) adding a fraction containing 90 per cent of the epoxide to 50 per cent volume/volume aqueous sulphuric acid; (5) adding a solution of the epoxide in cyclohexane at the bottom of a packed column cooled to about 30 DEG  C. whilst fresh 50 per cent aqueous (volume/volume) sulphuric acid is introduced at the top of the column; (6) running a crude oxidate containing the epoxide and unreacted di-isobutene into 50 per cent aqueous sulphuric acid, the upper phase is then distilled to give an unchanged diisobutene, a small amount of methyl neopentyl ketone and finally 2 : 4 : 4-trimethyl pentanal.

Title: Improvements in or relating to apparatus for electrical measurement
IPC: G01V3/06
Filed: 1944-12-04
Abstract: 612,813. Prospecting for ores; resistance measurements. TRIGGS, W. W. (Bolidens Gruvaktiebolag.). Dec. 4, 1944, No. 24215. [Class 37] For detecting subterranean deposits or for determining the resistance of electrolytes, ores and rocks, a current is employed which varies linearly with time. A Wheatstone bridge may be supplied with such a current. Fig. 3 shows apparatus for determining the potential distribution around a current electrode 7 put into the ground or into some other material. Linearly varying current is supplied from a source 1 to the ground through electrodes 6, 7 and a certain voltage is obtained between two potential electrodes 8, 9 put into the ground adjacent to the current electrodes 6, 7. This voltage is compensated by a voltage induced in a coil 10 and adjusted by a potentiometer 11 so that the instrument 2 reads zero. Figs. 4a, 4b and 4c show an arrangement for measuring electromagnetic fields. Linearly varying current from a source 1 flows through a coil 16, and the voltage induced in a frame 17, Fig. 4a, is compensated by the voltage from a coil 14 by means of a potentiometer 15. The relationship between the electromagnetic field at two points outside the coil 16 may be determined by comparing the voltages induced in two frames 18, 19, Fig. 4b. The direction of the field may be determined by inclining a frame 20, Fig. 4c. The currents employed-may be aperiodic when the measurement has to be performed in a very short time before the current and voltage reach high values. Alternatively, the currents may be periodic as shown in Fig. 5. A current 1 rising and falling rectilinearly with time is sent through a rectilinear cable, about which an electromagnetic field is produced. In a coil placed within this field a voltage 2 is induced. If there exists also an electromagnetic field from another conductor, a voltage 3 is induced, the resultant 4 of these voltages being measured by a compensator apparatus as described above. The voltage from the secondary field can be determined if the strength of the primary field is known. Currents of the required type may be produced by special generators or by means of rotating resistance discs. Alternatively, the substantially straight portion of the charge or discharge curve of a condenser may be employed, or a rhombic frame may be inserted with constant speed in a homogeneous magnetic field.

[Classes 83 (ii) and 83 (iv)] A cartridge-case, or like tube with a thickened closed end, is produced by applying axial pressure to a portion at one end of a tube, which portion is supported over its whole outer surface, but is free on its internal surface, the pressure being confined to this end portion of the tubing by an abutment member. Drawing; tube-expanders.-A drawn tube of cylindrical form is supported between a guide member 3, Fig. 9, and a matrix 4 having a bore 11 which is partly conical at the inner end, and the end of the tube projecting from the matrix is expanded by the enlarged portion of a mandrel 1. The abutment 5 and the mandrel 1 are retracted, and a series of balls 18, Fig. 11, are introduced through an inlet 10 and successively forced through the tube to expand the portion within the matrix against the wall of the bore, and then to draw out the tube in length. Alternatively, a long mandrel having a series of enlarged portions corresponding in size to the series of balls may be used. Forging; pipe-end closing.-The tube so formed is transferred to a press comprising a rotary matrix 31 having a gear 38 for engaging a driving pinion, a forming-tool 32 and countertools 34, 35, the portion of the tube of enlarged thickness then being acted on by the tool 32 to weld up the opening and to shape the base 23 to the required form. The matrix may be non-rotary and the counter-mandrel and the work rotated. The mandrel 32 may be advanced by a screw, a hydraulic press, or other means. The space 48 between the heads is filled with oil. The tube 50 after removal from the press is trimmed and shaped to the final form shown in Fig. 24.
