Title: Sheet transport system
IPC: B65H29/70
Filed: 1973-12-28

Title: Control of fluid pressure brakes
Inventor: WASHBOURN JACK
IPC: B60T15/04
Filed: 1968-12-18
Abstract: 1291230 Fluid pressure brake systems WESTINGHOUSE BRAKE & SIGNAL CO Ltd 28 Nov 1969 [18 Dec 1968] 60173/68 Heading F2F  Control apparatus for a fluid pressure braking system includes an overcharge arrangement is operable to adjust the fluid pressure to a value corresponding to an overcharge application by means which is set for a timed interval and is maintained set during that interval. In a two pipe system shown after the two vehicles are coupled a push button 37 is operated to actuate valve 35 which connects a supply input 36 to an input 35 of a valve 24 by way of double check valve 32, valve 24 thus being actuated to supply air from a reservoir 27 to a valve 21 and an overcharge reservoir 18 for a time controlled by a choke 28 and check valve 29. Air passes through valve 21 to act on a diaphragm of a relay valve 10 which transmits the overcharge pressure. When valve 24 closes at the interval during which overcharge pressure is applied, the overcharge pressure in the brake pipe is dissipated from chamber 102 through a choke 15 connected to atmosphere. If the brakes are applied before the overcharge is dissipated valve 21 is operated by brake cylinder pressure acting on a control input 22, to vent chamber 102 to atmosphere. Brake pressure also acts on a control input 34 of a valve 30 which connects a pulse reservoir 31 to overcharge reservoir 8, and remains open until the brakes are released, so that falling brake cylinder pressure allows valve 30 to connect reservoir 31 to an inlet of double check valve 32 which is thus operated to supply a control signal from reservoir 31 to control input 25 actuating valve 24 to restart the cycle as overcharge pressure is again fed to chamber 102. In a further embodiment for a one-pipe compressed air system the air supply and control signal pass through the same pipe. The control signals may be electrical.

Abstract: 610,351. Oscillating generators. QUINTON, A. J., FURZEHILL LABORATORIES, Ltd., and SMITH & SONS (ENGLAND), Ltd., S. March 28, 1946, No. 9701. [Class 35] [Also in Group XXXVI] An electromagnetic device for the interconversion of electric current and mechanical force comprises a current-carrying coil, at least part of which is of spiral shape, mounted to permit relative movement between spaced points along the coil and located between magnetic polepieces in such a manner that the magnetic field between the polepieces is transverse to, and preferably normal to, the plane of the coil. In the ammeter or voltmeter shown, the inner end 10 of a plane spiral coil 11 is fixed to a rotatably mounted spindle 12 whose axis is coincident with the axis of the spiral and the outer end of the spiral is fixed to the frame. A second spiral coil 13 of opposite hand is similarly mounted. The.centres of the two coils may be electrically connected through the spindle or otherwise and the two outer .ends of the spirals are connected to the terminals of the instrument. The coils 11, 13 are arranged in the air gap between the polepieces 14, 15 of a permanent or electromagnet 16. When a current is passed in series through the coils 11, 13, one unwinds and the other winds up so that both tend to rotate the spindle 12 in the same sense. The spirals 11, 13 may alternatively be connected in parallel and if their centres are connected together they will be of the same hand. A single spiral coil only may be used. The spirals 11, 13 may be of dished shape and the pole surfaces of corresponding shape. The invention may be used for generating in the coil an E.M.F. dependent upon a displacement.

Abstract: 706,244. Direct connections between conductors. PHILIPS ELECTRICAL INDUSTRIES. Ltd. June 6, 1952 [June 9, 1951], No. 14316/52. Class 38 (1) In order to prevent access of moisture or gas, a circuit component e.g. an electrolytic condensei is enclosed in an aluminium tube 2 into the open end of which is pushed an insulating plug 4, the edge of a rubber disc 5 of larger diameter folding over to form a seal when the end of the tube is turned over.

Title: Method and apparatus for controlling the evvect of the centrifugal force on the stock in pulp defibrating apparatus of the disc mill type
IPC: B02C7/12
Filed: 1979-02-12
Abstract: A method and apparatus is provided for controlling the effect of centrifugal force on pulp stock while being ground in the grinding space of a defibrating apparatus defined between a pair of grinding discs which rotate relative to one another in a fluid environment under superatmospheric pressure and corresponding elevated temperature. The grinding space includes a central portion, a first outwardly extending grinding space and a second outer grinding zone extending at an inclined angle from the first grinding zone. Pulp stock to be ground is introduced into the central portion and accelerated through the first and second grinding zones by centrifugal force generated by the rotating discs. The inclined grinding zone serves to split the centrifugal force into a vector perpendicular to the direction of flow of the pulp material and a vector aligned with the axial flow to reduce the accelerating force on the pulp grist in the direction of outward flow. By reducing the outward acceleration, the dwell time of the grist in the second grinding space is increased, resulting in optimum utilization of the entire grinding space for optimum refining efficiency.
