Title: Device for impartin an alternating rotary motion to a body about a mechanical axis
IPC: H01Q3/06
Filed: 1972-09-11
Abstract: 1394376 Control of A.C. motors THOMSONCSF 11 Sept 1972 [14 Sept 1971] 42173/72 Heading H2J [Also in Divisions G3 and H4] A motor 3 is coupled, for example by gearing 32, to a body 1 which executes rotational oscillations, for example an antenna, and to which are also connected resilient members 21, 22, e.g. helical, linear or spiral springs or torsion bars. A tachogenerator 5 detects the angular velocity of the antenna and feeds to an amplifier 4, connected to the motor, both a positive feedback signal via resistors R1a, R1b, and a negative feedback signal via resistors R4, R3, R2 and a negative gain amplifier 6. The tachogenerator 5 may be replaced by a device which detects the back e.m.f. of the motor 3. A resolver 7 detects the angular position of the antenna electrically, magnetically or optically and feeds an amplitude-dependent signal to the control electrode of a field-effect transistor Q1. The output voltage from resolver 7 may be first compared with a reference voltage. The output from Q 1 is applied to the junction of resistors R3 and R4 and increases the signal applied to amplifier 6. A starting and safety circuit 9 has a transistor Q2 which, when its base is negatively-biased, earths the junction of resistors R1a, R1b and prevents positive feedback to the motor. During normal operation the base is positively-biased by the output of an amplifier 92 fed by the output of resolver 7. If resolver 7 fails, the output of 92 becomes zero, supply 93 negatively biases the base of Q2 and the oscillations stop. Normal stopping is effected by a switch SW which in its off-position biases the base more negatively from supply 93. To start oscillations a positive pulse is applied to amplifier 92 from a supply 94 via a capacitor C and the positive feedback loop is rendered operative.

Title: Apparatus for jet texturing apparatus
IPC: D02G3/34
Filed: 1973-09-07
Abstract: 1427205 Texturing yarns ENTERPRISE MACHINE & DEVELOPMENT CORP 7 Sept 1973 [14 Sept 1972] 42278/73 Headings DID and D1F In a method of texturing yarn whilst producing variation in bulkiness along the length thereof, a yarn withdrawn from source is directed adjacent a pair of feed rolls rotating at different speeds and passed through a fluid jet device whereafter the textured yarn is wound. The running yarn is moved so as to be engaged alternatively with one and the other of the feed rolls thereby to vary the speed at which it is fed to the jet. The speed of and the speed differential between the feed rolls may be varied to produce any degree of intermittent bulkiness or thick and thin portions along the yarn and to form "reps" or slubs at variously spaced intervals. One or more e.g. core and/or effect, yarns derived from independent source(s) may also be fed by one (or the other) feed roller continuously and at appropriate speed so as to entangle, and be textured with, the first yarn within the jet. In the variable feed mechanism shown, a running yarn Y normally passes through the nip between spring-loaded idler roller 45 and a relatively slow-running feed roll 20. A solenoid 55 is energised at and for predetermined intervals, according to the control of a programme device 57 to move a rocker bracket 41 against the bias of spring 50 whereby idler roll 45 is withdrawn from operation contact with roll 20 and a hitherto inoperative idler roller 46 is forced into contact with a relatively fast-running feed roll 21 (driven through belt 28 and a multiple pulley 29) to form a nip therebetween through which the yarn then passes at increased speed.

Title: Improvements in seats
IPC: B60N2/50
Filed: 1965-10-06
Abstract: 1,119,902. Adjustable resiliently mounted seats. BOSTROM CORP. 6 Oct., 1965 [18 March, 1965], No. 42370/65. Headings A4J and A4U. In order to provide the same range of vertical oscillation for a resiliently mounted seat, irrespective of the weight of the occupant, the loaded seat is adjusted, to bring its equilibrium position to the midpoint of a fixed range of oscillation, on actuation of a control mechanism by the occupant. An independent height adjustment is provided to vary the height of the seat relatively to the pin 58, which is movable with the seat, is located at the midpoint of slots 76 in base housing 50, the ends of the slots defining the fixed range of oscillation. The seat frame 10 is supported, on parallelogram linkage 46, by a known form of air spring (16, Figs. 1, 3 and 4, not shown), connectible to atmosphere and to a source of high pressure air by a two way air valve 48. A control member 54 consists of two elongated side plates (56) joined by pins 58, 60 and 82, the latter pivotally supporting a lever 80, 86 between the plates. A T-shaped member has a cross-sleeeve 68 embracing the pin 60 and its shaft 70 supported for axial sliding in sleeve 72 against the action of compression spring 74. Rod 112 rotates crank 128 partially or completely to withdraw pin 60, by means of link 130, from the teeth of rack 64 fixed to seat frame 10. When rod 112 is actuated by the seat occupant partially to withdrawn pin 60, member 54 is moved to the right against the action of spring 74, but the upper end 130 of lever 80, 86 cannot follow this movement since it abuts the end of sleeve 72. The end 90 is accordingly pivoted into contact with valve-operating rocker 92. If pin 58 is not at the mid-point of slots 76, rocker 92 is tilted out of the vertical to operate air valve 48 and cause the seat to rise or fall until end 90 lodges in notch 96 and pin 58 lies at the mid-point of the slots. On further actuation of rod 112 and of sleeve 136, the seat occupant can completely withdraw pin 60 and turn shaft 70 to raise or lower member 54 and thus valve 48 is operated to cause a follower motion of the seat, which is terminated when pin 60 is re-engaged with a selected tooth in rack 64, and pin 58 again reaches its mid-point. A known damping device 140 (Figs. 1, 3, 4 and 9, not shown) is automatically brought into play when oscillations reach an amplitude at which pin 58 is brought near the lower ends of slots 76.
Patent GB-1016467-A (GB)
Title: Improvements in the production of phosphorus-nitrogen compounds
IPC: C07F9/54
Filed: 1964-10-16
Abstract: The compound <FORM:1016467/C2/1> is prepared by reacting diphenylphosphorus trichloride with ammonium chloride having an average particle size less than 10 microns in the presence of an inert liquid reaction medium at a temperature of 50 DEG  to 150 DEG C.  Usually the reaction medium will be a non-polar hydrocarbon or a halogenated hydrocarbon, particulalry alkanes having 6 to 10 carbon atoms and more especially n-heptane, halogenated alkanes having 6 to 10 carbon atoms and 1 to 4 halogen atoms and mono-, di- or tri-halogenated benzenes.  The diphenylphosphorus trichloride is conveniently obtained by chlorinating diphenyl-phosphorus chloride with gaseous chlorine in an inert solvent preferably of the type listed above, and the finely-divided ammonium chloride is conveniently prepared by passing gaseous streams of ammonia and hydrogen chloride into a rapidly agitated inert solvent. Preferably the reaction is carried out by mixing rapidly the diphenylphosphorus trichloride and the ammonium chloride, under anhydrous conditions. The desired compound may be isolated from the reaction mixture by filtration followed by extraction from the ammonium chloride with chloroform or alternatively the ammonium chloride may be removed from the filtered reaction mixture by extraction with water.  The compound is an intermediate for the production of phenyl substituted phosphonitrilic trimers and tetramers which it forms when heated to 200 DEG  C. and furthermore it may be reacted with phosphorus pentachloride and phenylphosphorus tetrachloride to give chlorosubstituted phosphonitrilic trimers and tetramers.
