Title: Improvements in rivet setting devices
IPC: B21J15/04
Filed: 1937-02-26
Abstract: 475,764. Setting hollow rivets. BEGG, R. H. Feb. 26, 1937, No. 5783. [Class 43] In joining two plates E by hollow rivets C, the rivets are set by drawing a headed mandrel A therethrough by means of a tool which comprises a nose 11 adapted to bear against a flange D on the rivet, a chuck 13 with gripping rolls 16 for engaging the mandrel, and a worm 37, preferably driven by an electric motor 51 in engagement with a worm wheel 34 which is associated with eccentrics 33 carrying straps 30 connected to the chuck 13 in such manner that rotation of the worm causes axial displacement of said chuck. The gripping rolls 16 are forced into and out of engagement with the mandrel by a pivoted lever 21 which actuates plates 19 having slots 18 which cooperate with the ends of the rolls, and the worm 37 is mounted in the tool by a pivoted bearing 38 and is retained in engagement with the worm wheel 34 by a hooked end portion 43 of a spring-pressed lever 44 which engages a lip 42 at the lower end of the worm, the other end 47 of the lever 44 projecting inwardly above the chuck 13. The arrangement is such that, after introducing the mandrel with a rivet thereon into the chuck, the lever 22 may be moved to cause the rolls 16 to grip the mandrel. The rivet is then inserted into the holes in the plates E and the switch 53 of the motor 51 moved to effect rotation of the worm and worm wheel and consequent axial movement of the chuck and mandrel to draw the mandrel through the rivet to expand and set the latter. At the end of this operation the chuck abuts against the projecting end 47 of the lever 44 and moves the hooked end 43 out of engagement with the worm to permit the latter to swing away from the worm wheel and prevent further movement of the chuck. The deformed mandrel is then released by actuation of the lever 21 and withdrawn from the tool.

Title: An improved process for the destructive hydrogenation of coal, tars, mineral oils and the like
IPC: C10G1/08
Filed: 1928-09-03
Abstract: 326,184. Johnsan, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 3, 1928. First Provisional Specification divided on 326,157. Catalytic materials.-In the destructive hydrogenation of carbonaceous materials in the liquid phase, catalysts immune to sulphur poisoning are used in the colloidal state. In an example a catalyst is made by grinding molecular proportions of molybdenum oxide, zinc oxide, and mag. nesia in the dry state and mixing the powder with an equal quantity of brown coal low temperature distillation tar. The mixture is passed through a colloid mill until 90 per cent of it will pass a sieve having 10,000 meshes per square centimetre. The catalyst may be regenerated by withdrawal from the destructive hydrogenation vessel and treatment with air at 120‹ C. In another example molecular proportions of molybdic acid and zinc oxide are mixed with 20 per cent of magnesia. and with water to form a paste which is dried and then rendered colloidal as in the previous example. Suitable catalysts for the process are described in Specifications 247,582; 247,583, 247,584, 249,493, [all in Class 32, Distilling &c.]; 249,501, 250,948, 251,264; 257,256, 258,272, 272,829, 272,830, 272,831, [all in Class 32, Distilling &c.]; 275,663, 275,664, 275,670; 276001, 285,923, 286,678, 286,679, 286,680, 286,681, [all in Class 32, Distilling &c.]; 293,719: 300,703, [Class 32, Distilling &c]; 307,946, and 311,251, [Class 32, Distilling &c.].

Title: Improvements connected with steam traps
IPC: F16T1/30
Filed: 1941-05-09
Abstract: 548,091. Steam traps. BAILEY, W. May 9, 1941, No. 6037. [Class 64 (ii)] A steam trap 1 is provided with a cover 2 having inlet and outlet openings 3, 4 in line. The inlet passage 5, 6 terminates below a strainer 15, above which is arranged an inverted bucket 10. An annular baffle 13 constrains steam and air to rise into the bucket. A valve 21 in the form of a metal stamping is mounted to slide on fixed vertical guide pins, and has a flange 22 which is engaged by a flange 12a on a guide tube 12 carried by the bucket to open the valve. If water only is delivered to the trap, the bucket remains in its lower position so that the discharge valve is open. If steam and air are delivered, water is displaced from 'the bucket, which rises and closes the valve. Air escapes through the opening 29 and steam condenses, allowing the bucket to fall, whereby air is discharged, together with water, until the entry of steam raises the bucket and closes the valve. An excessive inflow of steam is provided for by slots 30 in the guide tube, which permits escape to the exterior of the bucket. The passages 3, 4 may be connected and controlled by a hand operated valve which enables the trap to be cut out of the system.

Filed: 1924-03-12
Abstract: 234,218. Brown, W. J., Burch, C. R., Connor, R., Melling, C. T., and Metropolitan-Vickers Electrical Co., Ltd. March 12, 1924. Frequency, measuring. -- An apparatus for measuring the frequency of sound waves and other compressional waves and for analyzing a complex sound wave into its component frequencies comprises means for converting the sound waves into corresponding electrical oscillations in a circuit coupled with an oscillatory circuit which has adjustable tuning means and means for indicating the resonant response. A microphone or magnetophone 1 is connected, if necessary through an amplifier 2, to an inductance coil 3 having a fixed or variable coupling with a variable inductance coil 4, which forms an oscillatory circuit 6 with a variable condenser 5. This circuit is connected through a valve or other amplifier 7 to a telephone receiver 8 or other indicator such as a diode and a galvanometer. A reaction coil 9 may be added to facilitate sharp tuning. The adjustable elements 4, 5 are calibrated, preferably to indicate frequency directly. The tuned circuit 6 mav form the anode circuit of an oscillating valve having a grid coil coupled with the coil 4. In a modification of this arrangement, the detector 8 is connected across the output terminals of the amplifier 2, the amplifier 7 being omitted. A zero heterodyne method is employed in this case. In another modification, the output terminals of the amplifier 7 are connected to a neon or other glow-discharge lamp, instead of to the telephone 8, the lamp glowing whenever a potential difference above a definite limit is applied to the electrodes. The frequency may be determined by a stroboscopic apparatus co-operating with the neon lamp. The microphone may be replaced by a sensitive arc or glow discharge. A thermo-galvanometer or a thermionic voltmeter may replace the telephone as a detector. Other forms of oscillators than thermionic valve oscillators may be empolyed.
