Title: Domestic fire alarm
IPC: G08B17/06
Filed: 1964-02-20
Abstract: 1,088,554. Fire alarm systems. E. W. PRICE, and D. PENTELOW. May 14, 1965 [Feb. 20, 1964], No. 7120/64, Heading G4N. A fire alarm system comprises a thermal switch and a fuse connected across a power supply for a house lighting system, the arrangement being such that closure of the thermal switch due to abnormal temperature ruptures the fuse to initiate an. alarm. As described, the power supply live lead is connected to one side of an auxiliary fuse, the other side of which is connected to a first pair of normally closed relay contacts, and to one side of the relay coil. The other side of the coil is connected to the supply neutral and the other side of the contact set is connected to the lighting circuit. The auxiliary fuse and first pair of contacts are shunted by a pair of normally open contacts, and a further pair of normally open contacts connects the live supply lead to an alarm circuit. The thermal switch and its fuse are connected in series across the lighting circuit, so that an abnormal temperature condition ruptures both the fuse in series with the thermal switch and also the auxiliary fuse thus disconnecting the thermal switch and releasing the relay. The normally open contacts now close to restore the lighting circuit and energize the alarm circuit.

Title: Improvements in travelling wave tubes of the magnetron type
IPC: H01J25/44
Filed: 1955-03-10
Abstract: 781,208. Travelling-wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 10, 1955 [March 11, 1954], No. 7132/55. Class 39(1). [Also in Group XL(c)] In a pulse operated travelling-wave tube of the magnetron type, the cathode 1, Fig. 1, normally blocked, is unblocked periodically and the voltage applied between the delay line 4 and the negative electrode 2 is an alternating voltage with the peaks in synchronism with the cathode unblocking pulses. The cathode 1 is grounded except when negative pulses are supplied to it by way of a transformer 9 from a source 10. Source 10 is synchronized with A.C. source 12. Positive pulses may be applied to an auxiliary electrode 3. In another embodiment, Fig. 3, with coaxial electrodes 2, 4, a circular magnetic field and a radial electric field, cathode 1 is normally held by the emission at the potential of electrode 3, but is periodically grounded by a rotary switch 19. The pulsing system of Fig. 1 may be used instead, and both the electric and magnetic fields may be alternating. Specifications 751,034 and 753,688 are referred to.

Title: Process for redicing the concentration of fertilizer particulates in exhaust stack gases
IPC: C05G3/20
Filed: 1972-02-16
Abstract: 1381526 Reducing dust emission in fertilizer manufacture ROYSTER CO 16 Feb 1972 7151/72 Heading C1B [Also in Division F4] In the manufacture of fertilizer compositions, wherein fertilizer particulates are heat-dried and air-cooled, a process for reducing the emission of fertilizer dust to the atmosphere in the cooling phase of the operation, comprises spraying the air-borne fertilizer particulates with an aqueous solution of a nitrogen-containing salt or fertilizer at the beginning of said cooling phase. The particulates become bonded to each other and to larger particles, e.g. by the creation of interparticle salt bridges. The aqueous solutions used may contain ammonium orthophosphates, ammonium polyphosphates, calcium nitrate, ammonium nitrate, urea, urea phosphate, urea nitrate and mixtures thereof. The invention is illustrated with reference to a flow sheet (not shown) wherein a rotary drum cooler is used and wherein the treated cooler air stream also passes to a conventional cyclone duct extractor. In general, the anti-dust solution is injected by spraying on to the face of the falling screen of granular fertilizer at the point or intersection of conveyer flights and lifting flights of the rotary drum cooler. If a cooler other than a rotary drum type is used, it is preferable to pre-treat the feed material for the cooler by spraying same in a small inclined drum, a short section screw conveyer, a short section of a belt conveyer, or in a feed shoot to the cooler. The examples illustrate reductions of 79À7% and 71À2% in emission of dust.

Title: Improvements in or relating to memory systems employing a magnetic recording medium
IPC: G11B5/596
Filed: 1967-02-17
Abstract: 1,127,563. Automatic position control. INTERNATIONAL BUSINESS MACHINES CORP. Feb. 17, 1967 [ March 2, 1966], No. 7584/67. Addition to 987, 357. Heading G3R. [Also in Divisions G4 and G5] In a memory system according to the parent Specification in which a magnetic transducer is positioned over a desired data track by a servosystem actuated in response to servo-signals recorded in tracks adjacent the data tracks, the servo-signals in adjacent tracks are of the same frequency but have portions in anti-phase so that when the transducer is positioned over the desired data track no servo error signals are produced. As described, a disc 10 (Fig. 1) has magnetizable layers 11, 12 respectively of high and low coercivity and carrying respectively servo-tracks ST 1 -- Fig. 3 (not shown) and data tracks DT 1  -- spaced between the servo-tracks. The servo-tracks may, however, be arranged above or below the associated data tracks. The servo-signals (Fig. 4) are sinusoidal over most of their length but are reversed in phase at selected points such as 1 1 -1 3 , t 1  and 1 4 , t 2  so as to define periods a 1 , b 1  &c. of duration indicative of particular tracks by which coarse positioning of the transducer is achieved. The main leading and trailing phase reversals 1 2 , 1 4  and t 1 , t 2  are arranged on radial and spiral lines LR 1  - - - and LS 1  --- respectively. Servo-control: The servo-signal picked up by the head 21 (Fig. 1) takes the form of a suppressedcarrier, double-sideband signal which is separated from the data signals by a band pass amplifier 23 and smoothed by a filter 31 so that the resulting servo-signal has positive pulses at the radial lines and negative pulses at the spiral lines. The radial and spiral line pulses are separated at 32, 33 and fed to a coarse position detector 40 (also Fig. 2) to position the head near the addressed track. The positive (radial) pulses actuate an oscillator 46 to start a binary count cycle whose instantaneous value is compared with an address register 41 and a differentially timed pulse generated, when the values are equal, for comparison in phase discriminator 62 with a negative (spiral) pulse, the output of the discriminator controlling the head position actuator 64. A gate 61 is arranged to be opened when the coarse error signal from the detector 40 is minimal so that fine position signals, filtered from the amplifier 23 and demodulated 52, may pass to a summing gate 62 and thence to the actuator 64, control stability being improved by a tachometer. The demodulating carrier is derived from oscillator 46 in the detector 40 and the resulting, demodulated fine error signals are of amplitude and polarity indicative of magnitude and direction of error.

Abstract: 609,356. Means for producing linear motion. HICKLING, F. O. March 12, 1946, No. 7665. [Classes 80 (i) and 8.0 (iii)] Cam mechanism for steering gears and other purposes comprises a driving shaft 6 having a gear 5 meshing a gear 7 on a rod 1, the latter having a cam groove 9 engaged by a pin 10 fixed in the casing 3. Thus rotation of the shaft 6, which may be a vehicle steering column produces axial movement of the rod 1 which is also caused to revolve by the spiral gear 9 and cam pin 10. The latter absorbs shocks transmitted from the road wheels to the rod 1. In a modification, the gear 7 and cam surface 9 are superimposed. In a further modification, the members 7, 9 are rotatably mounted on the rod 1, which is slidably mounted in the housing 3, and in this case the rod 1 and the part carrying the cam 9 and gear 7 may have a screw-threaded connection with one another. The cam 9 may be of variable pitch.
