Title: Horizontal press, especially for trimming flash on elongated workpieces with non-circular contour
IPC: B23D31/00
Filed: 1965-03-16
Abstract: 1,074,661. Transferring blanks; trimming. SMERALOVY ZAVODY, NARODNI PODNIK. March 16, 1965 [March 23, 1964; April 3, 1964; April 14, 1964], No. 10984/65. Heading B3W. A horizontal trimming press for removing the flash from workpieces of non-circular cross-section has means for transferring the workpieces from a shoot to the trimming dies, said means comprising a withdrawal lever 3 to receive workpieces from a shoot 1 and convey them to an aligning head 11, and a transfer lever 4, having clamping jaws 25, 26, Fig. 4 (not shown), for transferring the workpieces from the aligning head to the trimming tools, the transfer lever 4 being freely mounted on a cam-shaft 13 and the trimming tools being rotatable during a closing movement to effect final alignment of the operating faces thereof with the workpiece. The press comprises a crank-operated tool-slide 8 which carries the trimming punch 6 and a spring- loaded ejector 7. The punch 6 co-operates with a trimming die (5), Fig. 2 (not shown). The workpieces, for example T-headed bolts, are gripped by spring clamping jaws on the lever 3, withdrawn from the shoot 1 and swung to a horizontal position in front of the aligning head 11, which is spring-pressed against the bolt-head. The aligning head 11 is then rotated through 360 degrees by a rack 17 which drives a pinion on the head and is itself driven by gears and a system of links 15, 16. The bolt is then gripped by the jaws (25, 26) on the transfer lever (4), Fig. 4 (not shown). The jaws (25, 26) are pivotally mounted on an upper block (19) and are connected to links (31 and 32) which are pivoted to a lower block (18). The blocks (18 and 19) slide in a recess in the lever (4) and are biased apart by a spring (20). The two blocks (18 and 19) are pushed towards the free end of the lever (4) by a cam (28) acting through links (29 and 30), and a compression spring (33). When the block (19) abuts the end of the recess the jaws (25 and 26) are closed by further movement of the block (18). With the bolt gripped in its jaws, the lever 4 is now pivoted around the shaft 13 by a cam (34), Fig. 5 (not shown), acting through a link (36) and an adjustable link (37). As the bolt reaches the working station the slide 8 moves forward and the bolt is gripped between the die 5 and the spring-loaded ejector 7. A cam (38) then initiates reverse movement of the block (18) which first opens the jaws (25 and 26) and then withdraws them below the level of the workpiece. The lever 4 is then returned to its original position by a cam (22) acting through links (24, 36 and 37). The die (5) is split along a diagonal line and is partly open when the slide 8 begins to move forward. When the flash on the bolt-head reaches the face of the die, the die halves begin to close, finally aligning the bolt-head in the die. The opening and closing movement of the die (5) is produced by a pair of cams (46, 47) operating toggle mechanisms (14), Fig. 1 (not shown).

Title: Improvements in the surface treatment of plastic materials
IPC: C08J7/14
Filed: 1943-07-06
Abstract: Hydrophobic surfaces of plastic substances obtained by polymerization of monomeric unsaturated organic esters alone or together with other copolymerizable organic compounds are rendered hydrophilic by superficial treatment with the vapour of fuming sulphuric acid or sulphur trioxide or with a liquid concentrated strong acid, followed by washing with an inert solvent until neutral and/or by an alkaline washing.  The treatment may be carried out at normal temperatures or at raised temperatures below the softening point of the substance. Specified liquid concentrated strong acids are sulphuric, chlorsulphonic, hydrochloric, nitric and phosphoric acids.  Water is the preferred inert solvent, but alcohol may also be used.  In the alkaline washing sodium and potassium hydroxides, ammonia and triethanolamine may be used.  The process is applicable to the treatment of substances obtained by polymerization of methyl methacrylate and acrylic esters, chloracrylic esters and vinyl esters of organic acids as well as to their copolymers with other copolymerizable organic compounds and to mixtures thereof.  Where transparency is important, the dried treated surface may be pressed between polished hot moulds or it may be embossed.  Water spreads evenly over the treated surface and it may be dyed from aqueous solutions.  Adhesives, e.g. glue, dextrin and silicates adhere readily to the surfaces.  The process may be limited to the treatment of a part of the surface which when dyed forms letters or other shapes.  Variations in the depth of colour may be obtained by gradually withdrawing the treated surface from the aqueous dye solution.  Windows formed of the treated surfaces are free from "misting" effects.  Antifreeze solutions are more evenly distributed over the treated surfaces.  Specification 494,031 is referred to.

Title: Improvements in or relating to communication systems
IPC: H04Q1/446
Filed: 1957-04-04
Abstract: 839,478. Automatic exchange systems. GENERAL ELECTRIC CO. Ltd., and TAYLOR, H. B. April 2, 1958 [April 4, 1957], No. 11026/57. Class 40 (4). In a system employing voice-frequency supervisory signals the operation of the voicefrequency receiver at an exchange interrupts the transmission of speech signals in both directions over the junction concerned so that false operation of the receiver by speech signals cannot persist long enough to simulate a supervisory signal. In the arrangement described the invention is applied to carrier working between two exchanges, the receive pair 1 (Fig. 1) and transmit pair 2 of a junction being connected through a terminating set 3 to a two-wire circuit 4 of the near end exchange. Two separate cables or two radio links are used for the receive and transmit channels, respectively. V.F. signals are applied over leads 12 to the transmit modulator 5. Signals incoming on pair 1 are connected over leads 16 to the V.F. receiver 14, which is shown in detail in Fig. 2, where they are amplified by tube 19. Circuits 22 and 24 produce opposing unidirectional voltages across resistors 23 and 25 proportional to the total signal, and twice the signal having the supervisory frequency, respectively, so that only if a supervisory signal or a speech signal having a large proportion of the supervisory frequency is received does tube 28 pass sufficient current to operate relay R. Relays S and N are normally operated, contacts S1/2 and S3/4 (Fig. 1) completing the speech transmit and receive circuits. When R operates, current flows through the winding 15 of S and rectifier 32 to charge capacitor 33, thus delaying the release of S by about 35 ms., and contacts R2 short-circuit the high resistance relay N which holds for about 200 ms. The release of S disconnects the source of speech (two-wire circuit 4) so that if the operation of R is caused by speech signals, R releases before N can do so, but S does not re-operate until 33 has discharged through its opposing winding 31 in order to ensure that R is released for a long enough time to prevent N releasing in response to repeated operations of R. If the operation of R is caused by a voice-frequency signal from the distant exchange the release of S will not result in the release of R, and after about 200 ms. N will relapse to initiate release of the near end exchange equipment.

Abstract: 214,086. Clench, C., and Aster Engineering Co. (1913), Ltd. April 21, 1923. Actuated or applied by running axle or wheel; blocks acting on drums.-In vehicle brakes of the kind comprising a pair of pivoted shoes 3, 4 adapted to be engaged with the brake drum 1 by a cam 10 actuated by a relay lever 11 carrying a brake shoe 13 that tends to revolve in the drum when frictionally engaged with it, the leverage exerted by the relay lever is constant throughout its movement and that on the cam varies only slightly. The lever 11 is mounted by means of a slot 12 of the form shown on the wheel axle 2, so that it is coaxial with the brake drum and may move either radially or angularly with respect to the axle. When the cam 17 is rotated by the brake-actuating shaft 18, the radial movement of the lever 11 applies the shoe 13 to the drum and its subsequent angular movement applies the shoes 3, 4 to the drum through the lever 11, links 15, 16 and cam 10. The lengths of the links 15, 16 may be varied to alter the leverage between the members 10, 11.

Abstract: 1,095,079. Capacitors. AEROVOX CORPORATION. March 14, 1966 [March 31, 1965], No. 11131/66. Heading H1M. Wound capacitor section 10 consisting of interleaved metal foil strips and paper or plastics strips impregnated with dielectric fluid is located in can B filled with the impregnant, and ionic impurities derived from decomposition products of the impregnant are immobilized by a pair of U-shaped compressed Kraft paper members 11, 11<SP>1</SP> impregnated with a stabilizer. The stabilizer, forming 30 to 90% of the paper may be the activated oxide, hydroxide or hydrated oxide of magnesium, aluminium, silicon or titanium, bentonite, Fuller's earth, and aluminium silicates. Since the paper members are in a region where the electric field of the capacitor is less than 200 volts/mil. there is no weakening of the bond between the stabilizer and the decomposition products as is the case when the stabilizer is incorporated in the paper spacer of the capacitor section proper. Moreover, thick paper may be used. The paper members may be curled over at the top as in Fig. 3 (not shown), or in the form of a sleeve surrounding a central metal rod extending through the core of the capacitor, with additional paper caps over the ends of the capacitor section as in Fig. 4 (not shown). The additive should pass a 100 mesh screen, and may be incorporated during the paper-making process. The dielectric fluid may be chlorinated diphenyl, mineral oil, castor oil or silicone oil.

Title: A control device for reciprocating machine tools
IPC: B23D7/00
Filed: 1956-04-12
Abstract: 825,289. Copy-milling. STARRFRAESMASCHINEN A.G. April 12, 1956 [April 15, 1955], No. 11201/56. Class 83 (3). [Also in Group XXIX] The reciprocating spindle-head 8 of a milling- machine attached to a piston 10 is displaced by the latter along a workpiece, not shown, until a gauging-pin 6 in the head 8 abuts one of two contact wires 40, 50, which form a template and have a contour corresponding to that of the finished work, and causes energization of one or other solenoid 2, 3 which moves a valve 5 controlling the admission and exhaust of pressure medium to and from the cylinder 11 of piston 10. Upon contacting the other wire 40 or 50, the opposite solenoid 2 or 3 is energized to reverse the valve 5 and direction-oftravel of the piston 10. This cycle will continue until the machining of the work is complete. Adjustable-stops 17, 18 and a rod 19, slidably guided by a stationary member on the machine-frame, limit the straight-line travel of head 8 by cam-operation of the switch members 22a, 22b of a switch 22, which members also control the solenoids 2, 3 to effect reversal of the piston 10, should the head 8 impinge upon either stop and displace the rod 19; the latter is returned to its original position by a pair of spring-loaded levers 20. Should either of the switch-members 22a, 22b fail, upon the head 8 contacting stop 17 or 18, the switch 22 is displaced with its slide 23 to actuate a safetyswitch 24 and stop the machine. Two pushbuttons 25 enable the movement of the head 8 to be reversed at will. In a modification, the contact wires have a common junction with the safety switch 24, and the solenoids are actuated through a reversing relay. The contact wires may be replaced by electrically-conductive templates.
