Title: Spray head for swirling spray
IPC: B65D83/14
Filed: 1963-04-25
Abstract: 1,032,065. Spray-producers. E. M. GREEN. April 25, 1963 [May 31, 1962], No. 16405/63. Heading B2F. A spray head of the push-button type for an aerosol sprayer comprises a body moulding 50 having an integrally formed valve actuating slidable depending hollow tubular member 38, an axially located feed conduit 44, a cavity 54 and a combined post and mandrel 60, 62 also formed integrally with the body and disposed coaxially in the cavity 54 to form a regular annular space  therewith. The cavity also incorporates a beading 70 for engagement with an annular groove formed on the external cylindrical wall 68 of a cup-shaped inset 64. The latter incorporates a nozzle orifice 74, a cylindrical chamber 78 and a square shaped chamber 76 connected by tangentially arranged channels 79, 80, 82 and 84 formed in the base wall 66 of the insert with respective passages 110, 111, 112 and 113 which are formed between the conduit 44 and the channels when the insert is fixed in the cavity 54. As shown in Fig. 7 the internal surface of the insert wall 68 is of square cross-section and so dimensioned that the post 60 forms the said passages 110, 111, 112, and 113 which communicate with the conduit through two ports 56 and 58. The mandrel 62 protrudes through the chamber 76 and partly into the chamber 78 to form an annular opening between the two passages. Through the disposition of the channels 79, 80, 82 and 84 and the location of the mandrel 62, the chamber 76 imparts a swirling motion to the pressurised mixture passing therein from the container 14 whenever the spray head is depressed, such depression causing downward or valve opening actuation of a spring-loaded valve member 13 by the depending tubular member 38. This swirling motion is smoothed down in the adjoining chamber 78 which is cylindrical and leads to the nozzle orifice 74. In a modification the depending member 38 is eliminated, the spray head being fitted, when required, to valve mechanism through the interconnection of a recess formed in the underside of the body moulding and a tube upstanding from this valve.

Abstract: 1497939 Axis-crossing detectors DATA RECORDING INSTRUMENT CO Ltd 26 April 1976 [24 April 1975] 16930/75 Heading H3P An axis crossing detector comprises means deriving first signals for all axis crossings delayed by a predetermined time relative to the axis crossing times, means deriving second signals indicating that the input signal has crossed a zone lying between a pair of reference levels lying one on each side of the axis and means for combining the first and second signals to produce delayed signal outputs only in respect of significant axis crossings. As described, the input signal, e.g. the differentiated read out signal from a digital magnetic recording, is applied to a limiting amplifier 11, Fig. 5, providing antiphase two level outputs 28, 29 depending on the polarity of the input. Outputs 28 and 29 are combined in a delay and gating arrangement 13 to provide a pulse train J comprising pulses of predetermined length at the beginning and end of long transitions and double short pulses for short transitions. The input signal is also applied to a limiting amplifier with hysteresis provided by resistors 39, 41 which changes its output only when the input has crossed a zone lying on either side of the axis. This output is processed in an arrangement 16 similar to 13, and the resultant pulse train M is added to a delayed version of J to give pulses at N corresponding to significant transitions only. In another embodiment, Fig. 7 (not shown) delay 14 is provided by a monostable circuit whose output is steered by the output of amplifier 37 to set or reset a bi-stable circuit.

IPC: B23K20/04
Filed: 1957-05-28
Abstract: 865,658. Making composite metal strip; jointing by rolling. TEXAS INSTRUMENTS Inc. May 28, 1957, No. 16971/57. Classes 83 (2) and 83 (4). In a method of solid-phase bonding of composite strip-metal, partial-strength bonds are formed by a sequence of at least two squeezing operations followed by a final sintering to form the permanent bond. In one example, metal strips 1, 3, Fig. 1, to be bonded pass through heating and scratch brushing apparatus 11 to remove surface film and through a dust-removing sweep chamber 13 before a two-stage reduction in roll stands 9, 23 to produce partial bonding prior to sintering. Rolls 17, 19, 21 between the roll stands guide the strips in a curved path to tension the strip 1 of softer metal and thereby assist in preserving the weak bond formed by the first roll stand 9. In modifications the initial weak bond may be preserved by guiding the strips between rolls or platens 31, Fig. 3, loaded hydraulically or by springs &c. Alternatively the initial weak bond may be preserved by driving the second set of rolls at a faster speed to maintain the strips under tension or by heating the strip to produce a partial sintering at temperatures below that at which brittle intermetallic compounds or liquid phases are formed. Examples are described for forming composite strips of copper and silver; copper and steel; silver and nickel; and aluminium and copper. Specifications 745,426 and 745,511 are referred to.

Title: R-f phase shifter
IPC: H01Q3/32
Filed: 1953-06-19
Abstract: 756,048. Phase shifting and attenuation networks. STANDARD TELEPHONES & CABLES, Ltd. June 19, 1953 [June 25, 1952], No. 17037/53. Class 40 (8). [Also in Group XL (c)] A phase shifter for use in an antenna system (see Group XL (c)) comprises a coaxial line 11 having a gap 15 in its inner conductor 14, and a coaxial inductive stub 18 coupled to the line. An endless carrier such as a disc 16 of low loss material, e.g. fibreglass, and having a metallic rim 17, is moved through the gap 15. In a modification (Fig. 10, not shown), where a large phase shift is required over a large bandwidth, three gaps may be provided in the conductor 14 each having an associated revolving disc and inductive stub. The phase shift may be made a sinusoidal function of time by forming the rim 17 of teeth 23, Fig. 4, shaped so that the width of metal bridging the gap varies sinusoidally. The teeth may be alternately of metal and an insulating material, to alternately attenuate and pass energy, allowing the apparatus to be used as a high-speed capacitive switch. If a gradual phase shift is desired from zero to some upper limit with an almost instantaneous return to zero, the teeth of the rim may be of a triangular shape, Fig. 8. If a phase shift is desired which will vary between two predetermined angles, the teeth may be alternately wide and thin (Fig. 9, not shown).

Title: Improvements in or relating to high frequency energy converting apparatus
IPC: G11B11/00
Filed: 1964-04-24
Abstract: 1,056,231. Magnetic recording. LITTON INDUSTRIES Inc. April 24, 1964 [July 2, 1963 (2)], No. 17151/64. Heading G5R. Information transmitted by a beam of radiated microwave energy is recorded on a heat-sensitive recording medium which moves relatively to a transducer comprising a mass of spin resonant material arranged in a magnetic field so that when the frequency of the radiated energy equals the resonance frequency of the material, or a part of the material, resonance occurs and heat is developed. The spin resonant material 13 is a rectangular slab over which the thermographic recording tape 11 runs. The magnet 17, 18 has non- parallel pole faces so that the magnetic field through the slab 13 varies from a maximum at one side of the tape to a minimum at the other. Consequently different points of the slab, across the width of the tape, have different resonant frequencies. A waveguide 14 brings the microwave energy to the slab and is arranged with a bend so as to permit the poles of the magnet to be as close as possible. Any particular frequency of microwave energy will cause resonance, and therefore local heating, at the corresponding part of the slab, and a mark will be made on the moving tape at the position corresponding to that frequency. The tape thus holds a record of the frequency distribution in the waveguide at all times. Since the spin resonant material responds to the magnetic vector of the electromagnetic wave, and since the electric vector would cause spurious heating of the tape, it is desirable that the former should be a maximum and the latter a minimum. If the spin resonant material is not a solid, it is enclosed in a suitable vessel. In another embodiment (Fig. 3, not shown) the tape passes through slits 29, 30 in the walls of a waveguide 22 terminated by a conducting wall 24. A coupling iris 36 is provided. In a similar arrangement (Fig. 5, not shown) the spin resonant material is supported on a tape guiding roller. The spin resonant material may be arranged diagonally across the waveguide and the magnetic field and the tape pass through at right angles to each other (Fig. 7, not shown). In a further embodiment (Fig. 12, not shown) the tape 20 is shielded from the microwave beam 23 except where it passes over the spin resonant material 72.

In an external contracting brake in which shoes 14a, 14b are moved about a common pivot 16 to engage or disengage a drum 11, a rod 15b slidably connects the free ends of the shoes and has slidably mounted thereon a piston 24a which acts in opposition to a spring 15d, embracing the rod, through a cylinder 15 pivoted to one shoe to move the shoes. Pressure below the piston 24a, which is held to the end of shoe 14b by abutment 15a and nut 23 on rod 15b, produces engagement of the shoes with the drum against the face of the spring 15d. On release of air pressure the spring releases the brake to the limit provided by the locknuts 20 and shoe centralizing stop 27. In a second embodiment, Fig. 3 (not shown), the spring is external to the cylinder and applies the brake, release being effected by air pressure on the piston.
