Title: Improvements in or relating to flexible electric heating hoses
IPC: B05B7/16
Filed: 1954-05-12
Abstract: 756,787. Electrically heated hoses. HERON, A. G. May 10, 1955 [May 12, 1954], No. 13857/54. Class 39(3). [Also in Groups XXVIII and XXIX] The electrically heated hose described in the parent Specification is modified in that one of two conductors consists of a length of flattened braided conducting wire D which is embedded in a strip of rubber C formed separately from the body of the hose A but bonded to the hose during manufacture of the latter. In Fig. 1 a braided wire conductor B of circular cross section is embedded in the body of the hose, and in the modification shown in Fig. 2, a number of series connected braided wire conducting strips E of arcuate cross section are provided. Fig. 3 shows how the hose A is connected to a spray gun G and to a step-down transformer F. The portion of the gun adjacent the passage leading to the spraying jet may be of metal and be included in the electrical circuit, the metal having an electrical resistance such that heat is generated up to the jet. The conductor D in the strip C may be of such a resistance that it dissipates heat as well as the conductor in the body of the hose ; alternatively, it may vertually constitute a conductor only. If the air supply to the gun is to be heated by a second hose as described in the parent Specification, the strip conductors of the two hoses are not used.

Abstract: 636,861. Grinding-machines. CLERK, A. C. (Clerk, E. J.). May 24. 1948. No. 14014. [Class 59] In a grinding mill wherein a rotor carrying grinding bars extending helically from end to end of the mill rotates wthin a fixed tubular housing the rotor bars are mounted so as to move outwardly under centrifugal force into engagement with the inner surface of the housing. As shown, helical bars 17 are housed in helical grooves in the periphery of the rotor 14, each bar being pivotally attached to the ends of the rotor by means of arms 19 and inclined pins 20. The rotor is given a ratchet-like crosssection by sharply cutting away the surface adjacent to the leading edge 17a of each bar and providing a smooth contour behind each trailing edge 17b. The material to be ground is introduced through hopper 21, ground between the bars 17 and housing 10, and discharged through opening 12. The housing may be conical and the rotor 14 may merely consist of a pair of end flanges connected by bars 17. Two rotors may be provided on the shaft the rotors having bars disposed at opposing angles so that material fed into opposite ends of the housing will be discharged between the two rotors. The bars may be resiliently supported in slots so that they will leave the periphery of the rotor and bear against the interior of the housing. At the feed end of the housing means may be provided for forcing in air under pressure so as to facilitate movement of the ground material through the mill.

Abstract: 609,206. Air heaters. RYLANDS, J. R., TILLOTSON, A. B., and PARRIS, C. W. Aug. 30, 1943, No. 14120. [Class 64(iii)] In a plate air heater, the heating gas passage 1, 2 is formed so that its cross-sectional area is gradually decreased from the inlet 3 to the outlet 4 and the velocity of gas flow therethrough is correspondingly increased; the width of the air passage 5 is also reduced from the inlet to the outlet so as to effect a simultaneous increase in the air velocity. In a tubular type heater the passage 1, 2 is replaced by a group of parallel tubes which decrease in diameter progressively from inlet to outlet.

Title: Improvements in or relating to telegraph systems
IPC: H04L5/14
Filed: 1928-05-14
Abstract: 319,032. Beatty, W. E., (Bell Telephone Laboratories, Inc.). May 14, 1928. Duplex telegraphs. - Cumulative unbalance effects in a system employing a loaded cable are reduced by the suppression of dots or isolated impulses by means of a wave filter at the transmitter; the system is particularly applicable to signals distinguished by change of polarity. Unbalanced effects (due to the difference in hysteresis characteristics between a loaded cable 10 and an artificial line AL) are found to accumulate owing to the slowness of propagation of signal impulses in the loaded cable, and the object of the invention is to reduce this accumulation by suppressing isolated impulses as distinct from blocks of impulses of the same polarity; in this way the frequency of the changes of polarity and also the mean voltage are reduced, since a succession of isolated impulses is represented by a period of zero current. The lost impulses are restored by a vibrator at the receiving station. The transmitting instrument T controls sending-on relays 22, 23 through a low-pass filter 25 which suppresses signals of frequency equal to or greater than that of a series of dots. When such a series occurs the cable 10 is earthed at E through the armatures 22a, 23a, which are held in the positions shown by the biassing circuit B; but when blocks of two or more impulses of like polarity occur, flat-topped signals of the appropriate polarity are sent on by these armatures, the coils 22b, 23b being adapted to overpower the biassing coils energized in the appropriate sense. The sent-on signals are applied to the apex 21 of the bridge. The inductance, cores in the artificial line may be made of compressed iron or permalloy dust. Restoring or modifying imperfect signals.-Incoming signals pass through a reshaping device comprising a shunted condenser 14 and transformer 15, amplifier 17, low-pass filter 19, amplifier 18, and vibrating relay 20 which reinserts the lost impulses to the receiver R.

Abstract: 271,256. O'Hanlon, F. T., and Pennington, A. June 14, 1926. Self-filling reservoir pens; caps.-The. nib-protecting cap of a sac self-filling fountain or stylographic pen is provided with a plunger or aircompressor by the actuation of which, when the cap is fitted on the rear end of the barrel, air and residue ink may be ejected from, and a fresh charge of ink drawn into, the sac. In the form shown in Fig. 1, a hollow plunger 6 is reciprocably mounted in the end of a cap-member 4, a spring ring 7 in the cap-member being adapted to engage a recess 9 in the plunger to prevent separation. Inward movement of the plunger is limited by a shoulder 10 in the member 4. An air-aperture 5 in the cap-member is adapted to be covered by the finger during compression of the air, and an air-aperture 2 is formed in the end of the barrel 1. The plunger may be adapted to screw into the end of the member 4 to prevent accidental operation. As shown in Fig. 3, a washer 13 provided with air-passages 14, is fitted in the end of the cap member and serves to prevent leakage when the cap is fitted on the nib end of the pen. The plunger 6 slides on the outside of the member 4 and is integral with a pocket-clip 11. The lower end of the plunger is adapted to snap over a split ring 7. In a modification of this form, the plunger may be under the influence of a spring tending to force it outwards, and retained in position by a spring ring thereon engaging a recess in the member 4 or by screwing. The washer 13 may be formed as a non-return valve, an air-aperture, closed by the finger during filling, being formed in the member 4. As shown in Fig. 6, the cap-member 4 is provided with a tube 18, and the plunger 6, which slides in an extension 20 of the member 4, is packed to form a tight joint with the tube. The outer end of the tube is closed and a lateral aperture 14 is formed therein. Withdrawal of the plunger forces air through the aperture 14, tube 18, and aperture 2 into the barrel. In a further modification shown in Fig. 7, a rubber teat is mounted in the extension 20 and is compressed by a lever 26 pivoted in the extension 20 and actuated bv the plunger 6.
