Inventor: JORDY ARNOLD
IPC: A62D1/00
Filed: 1967-02-09
Abstract: 1,150,682. Dry powder fire extinguishing compositions. NU-SWIFT INTERNATIONAL Ltd. 29 Jan., 1968 [9 Feb., 1967], No. 6140/67. Heaiding A5A. [Also in Division C1] A dry fire-extinguishing powder comprises ammonium sulphate, ammonium phosphate (mono-ammonium and/or di-ammonium phosphate) and potassium bicarbonate and, as inert additives, micronised minerals halving free OH-groups, the minerals having been dried to a moisture content of not more than 0.05% by weight and rendered hydrophobic by treatment with chlorine-free hydrogen silicone oils. #Micronised" is defined as 90% of the particles being <10Á, and "hydrogen silicone oils" as oils with silicon and hydrogen directly bonded. The minerals may be amphiboles or pyroxenes with free OH- groups obtained in geological development or by alkali hydroxide treatment. Preferably the ammonium sulphate and (phosphate are treated with neutral to acid minerals and the potassium bicarbonate with neutral to alkaline ones. The hydrogen silicone oil. may be augmented with a silicone oil without active hydrogen to the extent of 30% by weight of the mixture. Preferably each active ingredient is separately pre-mixed with inert additive before mixture.

Abstract: 812,914. Couching in high-speed papermaking machines. WALMSLEYS (BURY) Ltd., and TEMPERLEY, J. March 2, 1956 [March 2, 1955], No. 6149/55. Class 96. The web on the wire-cloth W of a high-speed paper-making machine after passing beneath edge trimmers E and an automatic crosscutter A enters the couch press T, C where it is subjected to low suction L and high suction H, and couched with the aid of a continuous stream of low-pressure air supplied through a duct D, pipes X and a nozzle N, a backing-roll B opposite the nozzle N and at a small clearance from the wire-cloth W being driven at about the web speed. The web then passes over a guide roll G to a suction wet-press U, S, on an underfelt F; the inclination of the web approaching the felt F being as little as possible. The roll B may be covered with a hard rubber compositions or may be chromium-plated, and the roll G which normally runs at half the paper speed may be surfaced with polytetrafluorethylene, or chromium-plated. Intermittentlyoperated pressure air jets J deflect most of the web downwardly after a breakage, a lead-strip being left to run through the machine.

Title: Improvements in and relating to the control of electrical pulse generators
Inventor: SCOLES GRAHAM JOHN
IPC: H03K5/02
Filed: 1962-02-19
Abstract: 964,739. Automatic voltage regulation. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 5, 1963 [Feb. 19, 1962], No. 6350/62. Heading G3R. An arrangement for stabilizing the amplitude of pulses produced by a pulse generator comprises a comparator which produces a signal corresponding to the difference between an amplitude-dependent voltage and a reference voltage, a circuit which produces an output below or above a predetermined level according to the sense of said difference, and a modifying circuit which influences the pulse amplitude in dependence upon said output. As shown, a D.C. signal which is a measure of the amplitude of an incoming pulse P is derived from stages A, B, C and D and is applied to a comparator E for comparison with a reference voltage; the resultant output from comparator E is applied to an amplifier F which is arranged to be overdriven so that its output is either fully positive or fully negative. The output from F is applied to an integrator G controlling the action of a stabilizing circuit H which thus acts on the pulse generator in a sense to correct any variations in the pulse amplitude. The output from integrator G which rises or falls according to whether the comparator output is positive or negative, determines the reference voltage of the circuit H which may be of the type described in Specification 964,509. The arrangement is such that deviations due to the pulse generator or to its power source are corrected within one cycle period by the stabilizer H, whilst slow changes including changes in the load are corrected by the other circuit sections, including the integrator G which has a time constant corresponding to several cycles of the pulses to be stabilized. Specification 873, 835 also is referred to.

Title: Improvements relating to escapement devices of telautographs or other instruments
IPC: G04C13/14
Filed: 1920-03-02
Abstract: 139,783. Hansemann, R. A. Sept. 19, 1918, [Convention date]. Escapements constituting gearing for obtaining intermittent motion.-In an escapement device of the type in which the escapement wheel is coupled to the driving shaft by springs tensioned by a constantly acting driving force, the wheel is provided with pins and is loosely mounted on the shaft between two disks formed with recesses which coact with the pins to limit the movement of the wheel. One end of a spring c is connected to the hub of the disk d, the other end being secured to a pin on the escapement wheel b. A spring c<1> is similarly secured to the hub of the disk d<1> and to the escapement wheel, the pins projecting into notches e in the disks. The clockwork k, l constantly tends to turn the shaft a and the disks d, d<1> in a counter-clockwise direction, keeping the pins in contact with the sides of the notches e and maintaining the springs c, c<1> in a state of tension. When the pallet f is moved by a current impulse and the escapement wheel is released, the springs immediately urge the wheel one step forward, whereupon the shaft a and the other parts in engagement with it are caused to follow the wheel by the constantly acting driving force until the sides of the notches e again strike the pins. Consequently at each current impulse only the wheel itself is first moved, its rapid response thus being unretarded by the inertia of other masses.

Abstract: 805,270. Hooks. M. L. AVIATION CO., Ltd. May 17, 1957 [March 6, 1956], No. 7033/56. Addition to 784,053 [Group XXI]. Class 89(2) [Also in Group XXI] Means 2 for releasably attaching equipment to an aircraft as claimed in the parent Specification includes a pair of jaws 3a, 3b wedged in the closed position by engagement with a member 17 extending from the gun 1, the member 17 being moved to disengage the jaws and release t!he equipment either by manual operation or by firing the gun. The jaws 3a, 3b are pivoted between depending flanges 4 of a cap 5 screwed on the lower end of the gun casing 6, which is carried by pivoted crutching mechanism 8 as in the parent Specification. Each jaw 3 has a pair of ears 15a<SP>1</SP>, 15a<SP>11</SP> and 15b<SP>1</SP>, 15b<SP>11</SP> wedged apart by projections 18 of the member 17 to hold the jaws in engagement with a lug 16 on the equipment. Integral with the wedge 17 is a cylinder 19 having sliding fit in a cylinder 20 slidable in a cylinder 22, which in turn is slidable in the casing 6. The wedge 17 and cylinders 19, 20 are supported by a rod 31 seated on the lug 16 and extending into an axial recess in the cylinder 19, where it is secured by a shear pin 21 passing through the cylinders 19, 20. On firing the gun 1, the cylinders 19, 20 and wedge 17 are forced downwards as a unit until cylinder 19 shears the pin 21, the movement of the wedge allowing the ears 15 to move inwards so that the jaws 3 open. The thrust may be transmitted to the lug 16 by the wedge 17 instead of by the rod 31. A member 35 screwed into the cap 5 has depending lugs 36 which engage the projections 18 and lock the wedge 17 against rotation. As.in the parent Specification, the cylinder 20 has an annular groove 40 into which balls 42 move to lock the cylinders 20, 22 together, so that the cylinders are jettisoned with the load. Before firing the balls are housed in openings in the cylinder 22 and recesses in the member 35. Parallel levers 45 pivoted between the flanges 4 bear against the wedge 1'7 to prevent upward movement tihereof. Each lever is also pivoted to a spring- stressed stirrup 48, the web of which bears against a plate 50. The stirrup straddles an electric plug 53 and socket 54 in firing connection with the gun 1. On separation of the plug and socket, the stirrup can be rotated to release the wedge for upward movement by hand. The plug 53 is secured to one of the flanges 4.

The lever g has an adjustable fulcrum h connected to a lever i which is adapted to be moved by the operator against one or other of stops j, k for determining the maximum or idling speed setting. A lever t is adapted to move the pump control rod independently of the governor for interrupting the fuel supply.
