Nov. 29, 1965 [Dec. 16, 1964], No. 50574/65. Heading D1P. Low-cellulose wood pulp, i.e. wood pulp containing not more than 60% by weight of cellulose the remaining material being non-cellulose wood constituents, is bleached by treating it at a temperature of 90‹ - 300‹F for up to 4 hours in an aqueous pulp slurry having a pH of 5.5-8 and containing 1-20% by weight of pulp and 0.1-2% by weight of thiourea dioxide based on the weight of the dry pulp, the thiourea dioxide being used either as the acid or an alkali metal salt thereof, e.g. the sodium and potassium salts. The aqueous pulp slurry may also contain sodium bisulphite in a weight ratio to the thiourea dioxide of up to 20 to 1 and/or up to 1% on the dry weight of the pulp of a polyphosphate, e.g. sodium tripolyphosphate, tetrasodium pyrophosphate and sodium hexametaphosphate. The pH may be adjusted by the addition of sodium or potassium hydroxide or carbonate. The pulp may be a mechanical pulp, e.g. a groundwood pulp produced by grinding wood logs on grinding stones or a refiner pulp produced by passing wood chips through a disc or other refiner to mechanically subdivide the wood into fibres, or a chemi-mechanical pulp produced by softening the wood prior to mechanical subdivision of the fibres by treating it with aqueous sulphite, bisulphite or other softening agent. The pulp may be produced from spruce, fir, hemlock, pine, cottonwood, aspen or poplar. The aqueous pulp slurry may be heated by external heating means or by passing steam through the pulp slurry.

Title: Self-Propelled Vehicle System for use in Transfer of Loads
IPC: B63B27/18
Filed: 1968-05-20
Abstract: 1,168,938. Trans-shipping at sea; winches. MINISTER OF NATIONAL DEFENCE, CANADIAN GOVERNMENT. 20 May, 1968 [29 May, 1967], No. 23986/68. Headings B8B and B8E. [Also in Division B7] In apparatus for conveying a load 23 from a supply ship 1 to a receiving ship 2 by a self propelled vehicle 17, means are provided for controlling the speed and direction of the vehicle. An electric motor 19 having a drive wheel 18 which engages a " highline " cable 3 is energized by an electric cable 28 connected via a console (not shown) on the supply ship. To avoid the vehicle 17 striking kingposts 5 or 8 under power from the motor 19, limit switches 34, 38 are operable respectively by bulges 31, 35 formed on the cables 3, 28. The switches cause the motor to be cancelled and brakes (not shown) on the vehicle to be applied. For releasing or retrieving the cable 3 as the distance between the ships randomly varies, the cable passes around a ram tensioner 11 to a winch 12. In order to avoid the vehicle striking the kingpost 8 with increased speed relative to the kingpost, due to the winch and ram tensioner taking in cable when the ships are approaching each other at the same time as the vehicle 17 approaches the kingpost, a line-direction sensing transducer 39 automatically cancels the vehicle motor 19 when the vehicle is approaching the kingpost 8 and the cable 3 is being taken in. The motor is allowed to start when the cable is released. Having secured the vehicle 17 to the kingpost 8 by a releasable latch 40 the load 23 is raised from deck level by a motor driven hoist 24 or a vertically slidable block 7. The vehicle, after release then proceeds under control of the console towards the receiving ship 2 until brought to a stop by the action of the switch 34. After unloading, the vehicle returns to the ship 1 subject to the action of the switch 38 and the transducer 39. Tension on the electric cable 28 is maintained by a biased reel 30.

Abstract: 775,579. Necktie retainers. MOUNTANOS, D. K. Sept. 20, 1954 [Aug. 18, 1954], No. 24034/54. Class 43. A necktie retainer comprises a length of wire 1 formed at one end into a loop or head 2 in the shape of an inverted triangle, the other end being shaped either to receive a securing- pin 5, Fig. 1, or as a pointed securing-hook 9, Fig. 2, adapted to be passed through the material of the necktie. The securing pin 5 is pushed into a loop 4 in the end of the wire and through the necktie into a hole 8 in a retaining plate 7, the pin being a tight fit in the hole. The length of wire intermediate the parts 3 and 4 is arched. In the alternative arrangement the end part of the wire is bent to form a loop 4, with the hook 9 at the extremity to engage in the narrow portion of the tie. In arranging the device the base of the wire triangle is inserted upwardly, either into the knot of a tie, or behind the knot so that the base bears against the neckband of the collar.

[Also in Group XXVI] A diaphragm-type air pump 12, Figs. 3 and 4, used for exhausting air from a centrifugal pump to prime it, is driven from the centrifugal pump shaft 5 through friction wheels 10, 11. Wheel 10 is urged into engagement with wheel 11, against the action of a tension spring, by an eccentric and a control lever 6. Any mud passing, on completion of priming, from the centrifugal pump and through the suction valve 13 of the pump 12 is deposited on the discharge valve 14 and is forced through the latter when it opens. The eccentric shown in Fig. 3 and the pivotal support for the wheel 10 shown in Fig. 4 may be omitted, the lever 6 then being vertical when the drive is engaged and pivoted at about its mid length, and carrying the wheel 10 at its lower end. Alternatively, the pump 12 may be driven from the shaft 5 through an oscillating beam acted on by a cam on the shaft 5, the lever 6 serving to hold the beam away from the cam to disconnect the drive.

A steam generator heated by a hot gas, steam or a liquid, especially a nuclear reactor coolant, e.g. heavy water, comprises an upright pressure vessel within which is coaxially located a downcomer tube 14 which passes through upper and lower headers 3, 10 which are connected by an annular bank of vertical tubes 8 surrounding the downcomer, the ends of the tubes being welded into the outer walls of the headers. The lower header is divided into four sections by vertical partitions. Two pipes 1 convey the heating medium into opposite sections of the lower header whence it flows upwardly in one half of the tubes 8 to the upper header and then downwardly in the remaining tubes to the other sections of the lower header to discharge through pipes 2. Water is admitted to the pressure vessel at 12 and evaporates as it rises past the tubes 8, steam discharging at 13 whilst unevaporated water returns to the bottom of the vessel through the downcomer tube 14. In a modification, Fig. 2 (not shown), the heating fluid is steam or a gas and is admitted to the upper header to flow downwardly in all of the tubes 8, cooled gas or condensate discharging from the lower header.

Abstract: 815,473. Phase-sensitive circuits. ULTRA ELECTRIC Ltd. Oct. 30, 1956 [Aug. 26, 1955], No. 24555/55. Class 38 (4). In a phase-sensitive discriminator the A.C. reference voltage is applied in parallel to the control grids of a pair of valves together with a D.C. bias voltage, the valves remaining cut-off until an input signal is applied to the grids in push-pull. An input signal is applied in pushpull, from transformer 13, 14, to the grids of valves 1, 2. An A.C. reference voltage from transformer 6 is applied in series with the terminals 5 of a D.C. bias source to the grids inphase, the circuit being balanced by a potentiometer 7. The input signal is either in-phase or anti-phase with the reference signal and in its absence the valves are just cut-off. When it is applied, one or other of the valves conducts depending on this phase relationship and unidirectional current, corresponding in polarity and magnitude with the phase and amplitude of the input, flows in the load between terminals 15, 16 or 15, 17.
