Filed: 1921-01-20
Abstract: 172,269. Halbergerh³tte Ges. Dec. 1, 1920, [Convention date]. Filtering.-Blast-furnace and like combustible gases are superheated prior to filtration by the direct introduction into them of a hot current which either gives its heat up to the gases or supports the combustion of a portion of the gases with consequent evolution of heat. Fig. 1 shows apparatus wherein the gas to be purified passes over a heating-coil 2 through which flows a hot current which is cooled by the gas to a temperature below the ignition point of the gas and either passed through a nozzle 4 into the gas or diverted by a valve 5 into the open air as at starting or stoppage of the purifier. The casing of the superheater 1 through which the gas passes is lagged with fire-clay or brickwork 6. Fig. 2 shows a forced-draught furnace or gas burner which supplies a hot current to the gas to be purified. Compressed air enters the cylindrical combustion chamber 1 by a pipe 2, and gas enters by a pipe 3. The ignition port 6 may be covered by an observation glass. The chamber may have a filling of firebrick or other refractory material. The combustion products at starting may escape by a port 7, afterwards being passed through a watercooled valve 8 to mix with the gas to be cleaned.

Title: Improvements in journal bearings
IPC: F16C33/10
Filed: 1944-02-18
Abstract: 585,394. Bearings. BOARDMAN, J. Feb. 18, 1944, No. 3095. [Class 12 (i)] In a journal bearing the wedge-shaped oil- 111m lubrication is effected by the stationary bearing bush being so supported in its housing as to distort under the working load to provide the wedge-shaped clearances between the rotating shaft and the stationary bush. As shown in Fig. 1 the bearing bush 10 is provided on its exterior with wedge-shaped recesses 13 and the intervening cylindrical portions 15 are firmly supported in a housing. Under working conditions the oil-film pressure causes a distortion of the bearing bush at the externally unsupported areas 13 so as to provide the required wedgeshaped oil-film spaces 23 on the interior surface 11 as shown in the developed view Fig. 3. Alternatively the housing may have the wedge-shaped recesses whereby a plain bearing shell becomes distorted under working conditions to provide the wedge-shaped oil-film spaces at the interior of the shell, Fig. 4 (not shown).

Title: Improvements in or relating to a shell fuze with direct impact and a clockwork-operated self-destroying device
IPC: F42C9/14
Filed: 1956-01-31
Abstract: 788,628. Projectile fuzes. JUNGHANS AKT. GES., GEB. Jan. 31, 1956 [Jan. 31, 1955], No. 3128/56. Class 9(1) A direct action percussion fuze for a projectile provided with a clockworkcontrolled self-destruction device has a safety device preventing initiation on the first part of the trajectory. The firing pin 13 axially aligned with a primer 14 and a detonator 15 passes through the clockwork movement and near its bottom end acts as an arbor for a regulator 19 comprising pallets 19a engaging a toothed regulator wheel 20 with a pinion 21 meshing with a train wheel 22 mounted on pinion 23 for free rotation about the pin 13. Elements 24, 25, 26 each comprising a wheel and pinion complete the gear train, element 26 being in mesh with a centrifugal driving segment 27. The movement is locked by a forked member 29 embracing the regulator 19 and having upturned ends 29a engaging the wheel 20, until the member 29 is moved radially outwards by centrifugal force sufficient to overcome a spring 31 engaged by a lug 29b of the locking member. A safety member 39 engaging a shoulder 13b of the pin 13 carries an arm 39b engaged by a pin 38 on a control lever 34 which meshes with the pinion 23 and has a pointer arm 34b which can be observed through a window 37 to determine whether the fuze has been assembled correctly. Member 39 carries a pointer 39c for inspection purposes. As the clockwork runs down, lever 34 moves until it is out of mesh with pinion 23 and, at the same time, the member 39 releases the firing pin, thus arming the fuze for impact operation: After a given time, if impact does not occur, the weighted segment 27 carries a pin 43 out of engagement with a lever 45, which then rocks to release a sleeve 47 surrounding the striker. A spring 49 then drives the sleeve on to a plate 50 to drive the striker against the primer. Premature initiation of the detonator 15 is prevented by a slide 53 adapted to rotate under centrifugal force to free the flash passage, the slide being prevented from returning by engagement with a spring. A foil may be placed between the pin 13 and the primer 14.

Title: Improvements in and relating to Electric Motor Driving Mechanism for Machines.
IPC: D05B69/12
Filed: 1916-03-03
Abstract: 104,390. British Thomson-Houston Co., (General Electric Co.). March 3, 1916. Sewing - machines; driving -- An electric motor 22 for driving a machine such as a sewing- machine 34 is controlled bv a friction brake which normally holds the motor stationary and is actuated from the pedal 16 by a chain 30 which first closes the motor switch and then progressively releases the brake to start the motor and control its speed. The brake-block 64 is pivoted to a lever 26 pivoted at one end 49 and connected at its free end to a spring 28, the other end of which is connected to a second lever 27. The end 55 of the lever 27 is formed with a slot 41 which is adapted to slide on the pivot 40 of the switch lever 39. A relatively strong spring 29 holds the lever 27 in its retracted position with the switch 38 open. When the pedal is actuated, the slot 41 slides over the pivot 40 and causes the spring 42 to close the switch 38. Further pressure on the pedal draws down the lever 27, thereby diminishing the tension of the spring 28 and consequently the pressure of the brake-block on the brake-wheel 33. The machine 35 and motor 22 are mounted upon a supporting base 4 which can be turned about a hinge 6 to lower the machine into the storage chamber 21, with the end of the base 4 resting against a stop 10<1>. The motor 22 is of high impedance and has its armature and field winding connected in series.

Abstract: 1381901 Repeaters KPKUSAI DENSHIN DENWA KK 25 Jan 1972 [25 Jan 1971 19 March 1971 14 April 1971] 3383/72 Heading H4R A repeater amplifier is included within the diameter of a coaxial cable and is embedded in the insulation between the inner and outer tubular conductors. An unreflective section of wave absorbing material is provided in the insulation and the amplifier is powered by D.C. appearing across a cut in one of the conductors. As shown the outer conductor is cut and separated by insulator 8 which lies between unreflective areas 5-1, 5-2. An amplifier is powered by the voltage appearing across capacitor 6 which is connected between the ends of conductor 2 and the signals are passed through high-pass filters 13, 13a for one direction and lowpass filters 15, 15a for the other direction of transmission. The sections 5-1, 5-2 formed by loading the insulating material with conductive material or magnetic material provide a large alternation of the signal which, together with capacitor 7, prevents interference between terminations 9, 9a; 10, 10a. The filters and amplifier units may be encased in rubber 16 to improve flexibility of the cable. In a modification the inner conductor may carry the power supply and be cut or alternatively if the straining wires la are cut a system of branched conductors may be used to provide mechanical strength. In a further modification the unreflective section may be achieved by providing a layer of resistive and magnetic material on the conductors, Fig. 9 (not shown).
