Abstract: 1,166,193. Tool-changing. MONARCH MACHINE TOOL CO. 24 April, 1967, No. 18872/67. Heading B3B. In a machine tool, tool-changing means comprise a pair of pivoted tong arms 39 movable by pneumatic means 61 in a plane for opening and closing the tongs and movable by rack-and-pinion means 25 in a perpendicular plane to swing the tool from a transfer station to an operating station, the transfer station being movable by a cam surface 29 through not more than 25 degrees. The tools are stored in conical sockets 19 in a turntable 17, which is indexed by Geneva gearing 52, 56, 57 driven by an electric motor 50 under tape control. The pinion 25 is oscillated by a fluid-pressure device 60 and swings the tong-carrying shaft 64 through a crank 69, a rod 67, and a gear segment 65. The cam 29 moves a rod 28 abutting a lever 59 to swing the table 17 and allow a tool to be moved into, or clear of, its socket 19. Thus, the sequence of tool-changing movements is: the tongs grasp a tool in a socket by its grooved portion 31 and lift it clear, the socket is swung aside, and the tongs are swung to bring the tool into alignment with the machine spindle 14. The tool is held in the spindle 14 by levers 91, 92 engaging bevelled surfaces 35 and actuated by a spring-pressed sleeve 88. To release the tool, the sleeve 88 is moved upwardly by pistons 98, the lower ends of the levers 91, 92 engaging a surface 36 of the tool to disengage the tapered surfaces 81.

Patent GB-954202-A (GB)
Title: Microporous thermoplastic material
IPC: C08J9/26
Filed: 1960-05-30
Abstract: Microporous material is produced by mixing two incompatible thermoplastic resins under sufficient heat and pressure to produce a plasticized mass, shaping the mass e.g. by calendering or extrusion, and backing out one resin with a solvent which does not affect the other. An ion exchange polymer and/or graphite may be added to the plasticized mixture of two resins. Medicaments, e.g. antiseptics, insecticides or bactericides may similarly be incorporated into the microporous material.  The amount of soluble resin may be adjusted to yield pores which exactly accommodate the increase in volume of the ion exchange resin on its conversion to the salt form, thus yielding a continuous ion exchange membrane.  Suitable insoluble resins are polyethylene, polypropylene, polystyrene and polyvinyl chloride. Suitable water-soluble resins for backing out are polyethylene oxide, polyethylene glycol and polyvinyl pyrrolidone.  In Example I, polyethylene is mixed with polyethylene oxide under pressure at 220 DEG -250 DEG F., on a mill, the mixture is calendered to sheet form at 250 DEG F., and then immersed in water for 1/2 to 4 hours.  II is similar, but methylcellulose is introduced into the pasturized mix to give a porous film suitable for use in dry batteries.  III. polymeric methacrylic acid was introduced into the plasticized mix of resins to produce after backing a cation exchange diaphragm.  IV. uses polystyrene sulphonic acid instead of polymethacrylic acid to give an ion exchange diaphragm. V. The ion exchange resin incorporated was a weakly boric one obtained by aminating with diethylenetriamine a chlormethylated copolymer of styrene and divinyl benzene VI.  A strongly basic anion exchange material obtained by aminating and quaternating a chlormethylated styrene-divinyl benzene co-polymer with trimethylamine was used.  Specification 896,800 is referred to.

In the arrangement according to Fig. 1, front and rear axles 12 and 13 are each connected to a vehicle frame 11 through torsion spring suspensions 16, 17 and 18, 19 respectively. Each of the suspensions 16-19 comprises a rubber torsion spring 34 having an outer tubular member 42, Fig. 8, rigidly mounted on a wheel axle longitudinally of the vehicle frame and an inner tube or rod 43 which projects from each end of the tube 42 and which is connected through a linkage to a respective pair of tubular framemembers 21, 22; 27, 28; 29, 31; 32, 33. Rubber or the like sleeves 44 and 45 are bonded to the rod 43 and to a metal liner 46, integral with and within the tube 42. The liner 46 is preferably sectionalized, the centre section serving as a spacer for the sleeves 44, 45. A boss 52 having an arm 53 at right angles to the rod 43 is mounted non-rotatably on a splined portion 51 at each end of the rod 43 and is embraced by friction-tight bosses 54, 55 integral with legs 56, 57 of a bifurcated lever 58 which is thus movable angularly, relative to rod 43. An upper web portion 63, Fig. 9, on the lever 58 carries an adjustable stop bolt 65 which co-operates with the arm 53 whereby the torsion spring may be pre-loaded and the height of the vehicle frame above the ground adjusted. The free end of lever 58 is pivotally connected to one end of a link 71 comprising spaced parallel plates 72, 73 which are pivotally mounted on a boss 75 of a bracket 76 integral with one of the frame members 21-33. A flat 79 on the underside of bracket 76 cooperates with a stop-bar 81 rigidly secured to the lower end of link 71. An inwardly projecting lip 83 of the bracket 76 supports a double-acting shock-absorber, preferably of the vane type, which is pivotally connected through a link 88 to a lip 91 projecting from and integral with boss 55. Upward deflection of the suspension is limited by rubber pads (Fig. 5, not shown). In a modification (Figs. 12 and 13, not shown), the lever 58 is connected through a link to the corresponding end of a similar lever associated with a second torsion spring having'an outer member rigidly mounted on the outer side edge of the vehicle frame. The invention may be applied to independent wheel suspensions or vehicles employing swing- ing half axles.

IPC: F16D13/50
Filed: 1951-08-15
Abstract: 699,380. Assembling clutches. CHURCHILL & CO., Ltd., V. L. May 19, 1952 [Aug. 15, 1951], No. 19238/51. Class 83 (ii). An assembly jig for transmission clutches comprises a rigid base 1 which may be bolted to the clutch casing 5 at or near some or all of the points at which the casing is normally bolted to the flywheel, said base being provided with or adapted to receive pressure pads or surfaces 7 which during use of the tool wholly or partially take up the position normally occupied by the friction discs and clutch plate. The jig is designed primarily for use with Borg & Beck (Registered Trade Mark) clutches. The base 1 has a series of holes 2-4; to accommodate different size clutches, which are bolted to the base by bolts 12. Nuts 13 of the clutch links 11 may then be unscrewed and the base plate gradually released from the cover 5 to take up the travel of the clutch springs 8, the clutch being thereafter easily disassembled. When assembling, the parts of the clutch and the spacers 7 are placed in approximate position and the base plate 1 tightened towards the cover 5 and the nuts 13 fixed. A gauge assembly, Fig. 3, screwing into the base plate 1 and having a finger 17 enables the clutch release levers 9 to be correctly adjusted by means of the nuts 13, or alternatively the clutch release lever plate may be interposed between the levers 9 and the gauge finger 17, and the parts adjusted. A hand-operated lever 21, Fig. 1, operating a dummy release plate 20, allows the clutch-operating conditions to be simulated while the clutch is in the jig, the clutch parts being thereby settled down by repeated operation of the release and the release levers readjusted before the clutch is replaced on the vehicle.

Filed: 1957-06-18
Abstract: In a process for making chloro-substituted organic sulphonyl fluorides sulphuryl chlorofluoride is reacted in the presence of a free radical initiator with an olefinic compound copolymerisable with sulphur dioxide.  The products of the process include compounds having the general formula:  <FORM:0869921/IV (b)/1> in which R, R1 and R11 represent hydrogen or alkyl radicals and n is an integer from 1-15.  Free radical-initiators specified include actinic radiation such as untraviolet light, an organic peroxide, e.g. di-tertiary butyl and benzoyl peroxide, or hydroperoxide or an aliphatic azo compound.  Among the many olefinic starting materials specified are included ethylene, propylene, butene, vinyl chloride and bromide, alkyl chloride, cyclohexene, cyclopentene, 1,3-dienes, undecylenic acid and the methyl ester thereof, undecylenic alcohol, allyl acetic acid, N-allyl acetamide, methyl allyl ether, ethyl allyl ether, phenyl allyl ether, diallyl ether, styrene, ortho-allyl anisole, orotho-allyl phenol and para-bromo-allyl benzene.  In examples the following olefines are reacted with sulphonyl chlorofluoride: Ethylene, propylene, isobutylene, butene-1, octene-1, octadecene-1, undecenyl and allyl chlorides, diallyl ether.  With the latter starting material a substituted tetrahydropyran is obtained.  The products of the examples may be converted to the corresponding sulphonic acids, metal and ammonium salts, acid chlorides and sulphonamides.  The corresponding sulphonic acids may be obtained by hydrolysis of the sulphonyl fluoride in hot alkali solution and decomposing the salt formed with strong sulphuric acid solution.  The metal and ammonium salts may be obtained by reacting the sulphonic acids with the metal or metal oxide and ammonium hydroxide.  The sulphonyl chlorides may be obtained by reacting the sulphonic acids with PCl5 or the salts with the PCl,2ZnCl2 complex.  The sulphonamides can be prepared by reacting the sulphonyl fluoridesor chlorides with liquid ammonia.  The chloro-alkane sulphonyl fluorides may be employed in the preparation of surface active agents, water repellant impregnants and coatings and epoxy resin curing agents. Specifications 758,467 and 869,922 are referred to.

Title: Clock pulse distribution systems

Filed: 1976-05-11
Abstract: 1531894 Processor clock pulse distribution systems INTERNATIONAL BUSINESS MACHINES CORP 11 May 1976 [27 June 1975] 19331/76 Heading G4A In a data processor, clock pulses from a fixed frequency source 12 are delayed at 14 and distributed at 16 to various parts of the data processor, both the delay and the distribution being determined by data sent from a control system 10, a detector 20 coupled to the control system 10 and to an output 18 of the distributor 16 determining the discrepancy (if any) between the timing of the distributed delayed clock pulses and the timing determined by the data sent from the control system 10 so that the clock pulse timing can either be controlled or measured. The delay circuit 14 passes the data from the control system 10 via a shift register to store a bit pattern in an array of memory cells, the output of the array for a particular input selecting the desired delay using coarse, medium and fine increments. The coarse delay increments are fixed delays inserted in a clock pulse path whereas the fine delay increments are switchable gates coupled to the clock pulse path. The distributor 16 also passes the data from the control system 10 via a shift register to store a bit pattern in an array of memory cells, the output of the array for a particular input connecting, one or more of the clock pulse paths to one or more of the outputs of the delay circuit 14 (a plurality of components 14, 16, 20 may be provided, each on a separate chip). In operation, if the detector 20 indicates non- comparison of the timings of the clock pulses applied thereto, the control system 10 alters the delay of the delay circuit 14 until comparison is indicated, which produces the correct clock pulse timing on the selected path. Alternatively, the delay of the delay circuit 14 may be maintained constant and an adjustable delay introduced by means of a circuit 24 into the reference clock pulses sent to the detector 20, comparison in this case producing a measure of the correct clock pulse timing on the selected path, since the delay introduced at comparison by the delay circuit 14 is known by the control system 10. The circuit 24 uses a voltage-controlled oscillator of frequency less than that of the source 12, the source 12, a phase comparator, a further voltage-controlled oscillator of frequency equal to that of the source 12 and a further phase comparator to establish the required delays of the reference clock pulses,  Figs. 9A, 9B, 9C (not shown).
