Title: Explosive charge assembly for directed blasting under high temperature conditions, such as tapping of blast furnaces
IPC: F42B1/02
Filed: 1948-10-04
Abstract: 658,625. Blasting devices. DU PONT DE NEMOURS & CO., E. I. Oct. 4, 1948, No. 25867. Convention date, Jan. 29. [Class 9 (i)] [Also in Group XII] An explosive device more especially adapted for tapping blast furnaces comprises a metal container 1, housing at one end an explosive charge 3 with a conical recess fitted with a rigid liner 4. The charge may be a 95-5 blend of cyclotrimethylenetrinitramine and high melting point wax, e.g., paraffin or Montan, pressed to a density of 1.6 gms. per c.c. in a thermosetting plastic casing 5. A packing 6 of asbestos or similar heatinsulating material holds the container 5 in postion. A booster charge 7, e.g., low density cyclonite is placed at the end of the charge in contact with an electric blasting cap 8, the cap being also surrounded by insulating material. The unoccupied part of the container forms a " standoff " for the charge which may be 2 to 5 times the diameter of the charge. The container 1 has removable end closures 2, 10. The electric blasting cap (Fig. 2) has a gilding-metal shell 13 containing a pressed charge 14 of cyclonite on which is superposed a primer charge 15 and an igniting composition 19 in which is embedded a bridge-wire connecting leg-wires 17 extending through a rubber plug 16. Alternative compositions for the main charge 3 are pentaerythritotetranitrate, ethylenedinitramine, cyclonite or mixtures of these with trinitrotoluene. The liner 4 may be of aluminium, copper, glass or steel and the preferred cone angle is 60 degrees. In tapping furnaces, a hole is first drilled through the clay plug at the base of the furnace and the device inserted in the hole. When the forward closure 10 contacts the iron shell of the furnace the device is fired. Specification 610,106 is referred to.

Patent GB-848006-A (GB)
Title: Improvements in or relating to apparatus for the determination of polarisation of very short radio frequency electro-magnetic waves
IPC: G01R29/08
Filed: 1956-08-24
Abstract: 848,006. Waveguide junctions. TELEFUNKEN G.m.b.H. Aug. 24, 1956 [Oct. 1, l955], No. 25970/56. Class 40(8). Waveguide apparatus for the analysis of the configuration of wave-energy comprises means for deriving from the wave to be analysed four energy portions proportional to the vertically and horizontally polarized components and to the clockwise and anticlockwise circularly polarized components into which the wave may be resolved. The input consists of a square-section waveguide 1 which divides at a junction 2 into equal squaresection branches 3, 4. Polarization filters (one only shown), consisting respectively of vertical and horizontal arrays of conductive members 6, are arranged between the input I and the branches 3, 4 such that the horizontal and vertical linearpolarized components of the input wave propagate respectively in the branches 3 and 4. Branch 3 is divided by a vertical septum 9 and branch 4 by a horizontal septum (not shown) whereby half of the energy in each guide may be derived at a pair of terminals guides 10 (one only shown). The other half of the wave energy in branch 3 propagates via an H-bend 12 and an E-bend 13 into the shunt arm of a magic-T junction 14. The other half of the wave energy in branch 4 propagates via an E-bend 15 into the series arm of the magic- T. The path length between the junction 2 and the shunt arm is greater by one quarter-wavelength than the path length between the junction 2 and the series arm. The two linearly polarized components of the input wave arrive at the magic-T 14 with a phase difference whose sign depends upon whether the horizontally polarized component in branch 3 initially leads or lags the vertically polarized component in branch 4, i.e. upon whether the sense of rotation of the input wave is anticlockwise or clockwise. If the input is circularly polarized the two components have equal amplitudes and will be either in phase or in phase opposition. Because of the properties of the magic-T junction the whole of the energy delivered to the junction appears either in arm 16 or in arm 17 depending upon the sense of rotation of the wave. If the input wave is not circularly polarized the components are unequal and the output of the energy is divided between the branches 16, 17. The ratio of the sum and difference of the two rectified outputs gives the degree of ellipticity of the input wave and the sign of this ratio gives the sense of rotation. The orientation of the input wave may be deduced by combining the values of the rectified outputs obtained at all four terminals 10, 10, 16, 17. The mathematics of the method used is given in the Specification. The magic-T junction may be replaced by a ring-hybrid and coaxial lines may replace some of the waveguides.

The composition may be applied to the hair either before or after arranging it in the desired configuration and the hair then set by treatment with a neutralizer or oxidizing agent.  The process is applicable to the waving of human hair and also for the straightening of curly hair.
Patent GB-1101092-A (GB)
Title: Phosphorus-containing polymers
IPC: C08G8/28
Filed: 1965-06-21
Abstract: Phosphorus containing polymers are prepared by reacting a phenol, an aldehyde and a trivalent phosphorus halide particularly phosphorus trichloride.  Two main methods may be used to form the polymers, viz.:-(1) by reacting a phenol and an aldehyde to form a thermoplastic polymer which is then reacted with phosphorus trichloride and (2) by reacting a phenol with phosphorus trichloride to form an aromatic phosphite which is unsubstituted in the 2, 4 or 6 position and reacting this phosphite with an aldehyde.  The preferred aldehyde is formaldehyde and the phenol may be substituted suitably by C4- 18 alkyl groups.  The phosphorus-containing polymers may be added as stabilizing agents to polymers subject to thermal degradation.  Such polymers may be styrene-butadiene rubber polyolefin resins, polyesters or polyurethanes.  The phosphorus containing polymers may be used in conjunction with an ester of thiodipropionic acid and/or a hindered phenol.  Examples describe the stabilization of polypropylene resins, ethylene/propylene copolymers, styrene-butadiene latex rubber crumb, a polyester, an ABS resin and polyethylene.ALSO:Gasolene, waxes, greases, natural and synthetic lubricating oils, jet fuel and heating fuel oil may be stabilized with phosphorus containing polymers prepared by reacting a phenol, an aldehyde and a trivalent phosphorus halide which is preferably phosphorus trichloride. The polymer may be prepared by reacting the phenol with an aldehyde to form a thermoplastic polymer which is further reacted with the phosphorus halide or by forming an aromatic phosphite from the phenol and phosphorus halide and reacting this phosphite with an aldehyde (see Division C3).

Title: Combined television receiver and broadcast receiver
IPC: H04B1/26
Filed: 1952-10-17
Abstract: 729,443. Radio receiving sets. STANDARD TELEPHONES & CABLES, Ltd. Oct. 17, 1952 [Oct. 26, 1951], No. 26107/52. Class 40 (5). A radio receiver for receiving alternatively television signals with concomitant sound signals and V.H.F. sound broadcast signals, comprises means whereby, during television reception, the concomitant signals undergo two stages of frequency changing to reach a final intermediate frequency which is reached, during sound-broadcasting reception, by one stage of frequency changing. The incoming signals are amplified by an H.F. amplifier 1 which is adapted to be tuned to either the sound-broadcasting band or the television band and then undergo a stage of frequency changing in mixer 2. Oscillator 3 is a variable-frequency oscillator which may be tuned to effect the conversion of the incoming signals to predetermined intermediate frequency at the output of mixer 2; in the case of television reception this intermediate frequency is converted to a second intermediate frequency by mixer 5 and fixedfrequency oscillator 6 for amplification in the sound I.F. channel 7. In the case of sound broadcast reception the oscillator 6 is switched out of circuit by the switch 8 and the tuning of the oscillator 3 is arranged to provide the second intermediate frequency directly at the output of mixer 2. The Specification describes how the local-oscillator frequencies are chosen to avoid interference by harmonics thereof within the television and sound-broadcasting bands.

Filed: 1932-09-20
Abstract: 391,676. Direct acting air compressers. PESCARA, R. P., 23, Rue Lesueur, Paris. Sept. 20, 1932, No. 26168. Convention date, Oct. 6, 1931. [Class 8 (i).] The outlet valves 45 of a direct-acting internal-combustion air compressor with freely moving pistons are held on their seats at starting by spring-pressed blocking members 44, air being delivered at this stage through an auxiliary valve 54 to the receiver 2. The pistons on which the blocking members 44 are mounted are subject to air pressure supplied by a pipe 58 through a casing having a control piston 30 an extension 25 on which controls also the outlet from the receiver to the outlet conduit 24. A spindle 57 on the control piston actuates through levers the feed control of the fuel pump 50. The motion of the control piston under the rising pressure in the receiver severs communication between the receiver and the pipe 58 and by opening the valve 38 allows this pipe to discharge to atmosphere. Undue rise of pressure allows the receiver to discharge through a relief port 56.

Title: Improvements in or relating to meteorological balloons
IPC: B64B1/58
Filed: 1945-10-11
Abstract: 601,919. Meteorological balloons. PAK PARACHUTE CO., Ltd., and CASPAR, F. A. Oct. 11, 1945, No. 26639. [Class 4] [Also in Group XL (c)] In order to render a meteorological balloon reflective to radar pulses, it is provided with a self-retaining cover enclosing it over a little more than half its peripheral surface and composed of a metallic or metallised open mesh material such as nylon coated with silver or other good electrical conductor. The cover is. constructed so as to adapt itself to variations in the diameter of the balloon due to changes in altitude and permit of a more or less free expansion of the balloon with increase in altitude. As shown, the cover 1 is of partspherical form built up from six gores 2 connected by seams covered by tapes 4 of woven net material, Fig. 2 (not shown). The seams extend to a binding vent 5 through which is passed the inflating neck of the balloon, the vent being enclosed by a fabric ring 6. The mouth of the cover incorporates elastic cords 7, Fig. 6, which exert a frictional grip on the balloon's surface, and the expansion of the mouth is limited by an inextensible binding tape 8 which encloses the cords 7 and is stitched to the edge of the cover. The diameter of this mouth when fully extended is slightly less than the maximum diameter attained by the balloon when in use so that at high altitudes the mouth bites into the surface of the balloon to form a peripheral channel or recess. Alternatively, the tension of the cords 7 may be such that, when the balloon is fully expanded, it is sufficient to form the peripheral channel or recess, in which case the diameter of the mouth of the cover may be made equal to the maximum diameter of the part of the balloon with which it contacts.
