Title: Non-activated-tank ship-stabilizers
IPC: B63B39/03
Filed: 1965-12-24
Abstract: 1,134,114. Ship stabilizing. NIPPON KOKAN K.K. 24 Dec., 1965 [29 Dec., 1964; 18 March, 1965], No. 54810/65. Heading B7M. A ship-stabilizer of the non-activated tank type comprises a pair of tanks 1, 2, Fig. 1, which are situated adjacent the sides 3, 4 of the ship's hull and connected to each other by a duct 5, air spaces 1a, 1b above the free surfaces of water in said tanks being connected to each other by a conduit or piping 6 containing a pendulum-actuated valve 7 so as to regulate the flow of air and water from one tank to the other in response to rolling of the ship. The valve includes a rectangular valve member 8, Fig. 3, which is attached at its uppermost edge to a pivotable rod 9 carrying a simple pendulum 13 externally of the piping 6, the bob-weight 14 being movable relative to the rod 9 so as to change the periodic time as required. A ridge 12 fixed to the piping co-operates with the valvemember in controlling the flow of air from one tank to the other. The valve may be modified, Figs. 4 and 5 (not shown), in that the pendulum 13 is replaced by a simple pendulum (17) containing a slot (16) that engages with a downwardly-cranked portion (15) of the rod to which the valvemember is attached, the pendulum being otherwise independent of the rod. In another embodiment, Fig. 8, the flow of air from one tank to the other through piping 6a is controlled by a combination of two pendulum elements 19, 20, the element 19 being supported by a pin 24 on a part of the hull and having an opening 21 therein which during operation of said element periodically comes into register with the ends of the piping, whereas the other element is supported by a pin 25 on the element 19 and has a shutter 26 that periodically obturates said opening. In yet another embodiment, Figs. 12 to 14 (not shown), the control valve comprises a simple pendulum (27) constituting per se a valve-member that periodically interrupts the flow of air from one tank to the other through piping (6b) and is lodged in a sealed housing (28) containing guide rails (30) for rollers 31 on the pendulum. In still another embodiment, Fig. 15 (not shown), the tanks are connected to each other by piping (6) that does not contain a control valve, the tank 1 being furnished with an air vent (32) controlled by a valve (A) somewhat similar to that according to Figs. 12 to 14, whereas the tank 2 is furnished with an air vent (33) controlled by a valve (B) having a pendulum type of valve-member with a partcylindrical portion engaging with arcuate guide rails.

Title: A system of time-division multiplex transmission via communications satellites
IPC: H04B7/155
Filed: 1970-11-19
Abstract: 1301206 Satellite communication systems INTERNATIONAL STANDARD ELECTRIC CORP 19 Nov 1970 [22 Nov 1969] 54991/70 Heading H4L  In a system of the type disclosed in Specification 1,300,960 in which each signal burst is preceded by a codeword for identifying the start of a burst, and an address code, means are provided at each ground station for detecting the start of the message bursts and the corresponding address signals without knowledge of the order of sequence in a frame or the number of the participating stations. The incoming bit sequence BF is supplied to an address receiver AE which detects the addresses of the originating transmitters under the control of bit clock signal b 1  and from thence to a correlation receiver KE which recognizes the start signal of a message burst. When a start signal is detected, a signal is supplied via output a to a store ZSP comprising a chain of three drift registers controlled by clock t 2 . The bits appearing at the junctions of the shift registers indicate the condition at a predetermined point of each of three successive frames and by a majority decision, i.e. 2 out of 3, the time position at which start signals are to be expected within the current incoming frame is determined at ZME. Since clocks t 1  and t 2  are independent of one another, incoming start signals in successive frames may fall in adjacent time positions and to allow for these slight variations the information is taken off from two adjoining positions of the shift registers at the junctions via OR gates 01, 02, 03. In the case of a positive decision an AND gate U 1  is enabled for a predetermined period via a device ZF and the next start signal from receiver KE transferred via the gate U 1  to the output line BZ and is also fed to the store ZSp. This also enables a gate U 2  and the address signal at detector AE is transferred to an address store ASp divided into three sections which are used cyclically for three consecutive frames, the store ASp being controlled by clock t 3  via a control device St. A device AME makes an address majority decision over three consecutive frames which is then supplied via line A for further processing. In a modification, Fig. 2 (not shown), the stores ZSp and ASp are combined into a single unit.

Polyvinyl alcohol filaments of non-circular cross-section are produced by spinning an aqueous solution in which polyvinyl alcohol is the predominant solute into an aqueous coagulating bath, having a temperature of 25‹ to 50‹ C. and containing from 210 to 600 grams per litre of one or both sodium hydroxide and potassium hydroxide and, optionally, lithium hydroxide through a spinneret having orifices of non-circular crosssection at a "draw-down ratio" of 0À8 to 2À0, particularly between 0À9 and 1À2. The "drawdown ratio" is defined as the ratio of the peripheral velocity of the first take-up roll to the velocity of extrusion. The coagulating bath preferably contains 290 to 400 grams of alkali metal hydroxide per litre and its temperature is preferably between 30‹ and 40‹ C. The concentration of the PVA in the spinning solution is preferably 13 to 23% by weight, being higher the lower the D.P. of the PVA. The PVA used may be completely saponified PVA, PVA containing a small proportion of residual ester and ether radicals, watersoluble PVA which has been subjected to some amination or sulphonation, or PVA possessing great stereoregularity. The spinning solution may contain, in addition to the PVA, gelatin, casein, starch, polyethylene glycol, emulsified polystyrene or emulsified polymethyl meth. acrylate. After leaving the coagulating bath the filaments may be neutralized by passing them through an aqueous bath containing sulphuric acid and a high concentration of sodium sulphate, wet drawn in a bath containing a high concentration of sodium sulphate, waterwashed, dried and wound upon a bobbin. The filaments may then be drawn, e.g. 150% at 230‹ C. and thereafter shrunk, e.g. 5%. The cross-sections of the orifices of the spinnerets used may be as shown in Figs. 1 to 4 and the cross-sections of the filaments obtained are very similar.

Title: Phase sequence comparator
Inventor: SPENCER DEREK JOHN
IPC: H02H3/38
Filed: 1966-12-20
Abstract: 1,168,459. Magnetic phase sequence comparator. ENGLISH ELECTRIC CO. Ltd. 19 Dec., 1967 [20 Dec., 1966], No. 56886/66. Heading H3B. [Also in Division H1] A phase sequence comparator for detecting the occurrence of two signals intermediate first and second limiting signals comprises a three-aperture magnetic core arranged such that an output signal is induced in an output winding threading one of the apertures when the two intermediate signals are applied to windings on the core intermediate the two limiting signals. Input pulses derived from different sinusoidal input quantities at the instants of transition between positive and negative polarity are applied in sequence to windings 2, 4, 5, 3 on a figure of eight magnetic core, the pulses applied to windings 2, 3 being the limiting pulses A, D and the pulses applied to 4, 5 being intermediate pulses B, C. If the sequence of pulses is ABCD or ACBD then an output is induced in winding 6. Fig. 2 (a)-2 (e) shows the sequence of flux patterns for the pulse sequence ABCDA. After the flux pattern has been set by a positive pulse A, Fig. 2 (a), positive pulses B, C reverse the flux around the upper and lower apertures respectively but not the flux in the two waisted portions. The second limiting pulse D applied to winding 3 reverses the fluxes in the inner limbs and sets up a flux pattern around the centre aperture, this reversal of flux producing an output in winding 6. The next pulse in the sequence is a negative A pulse which sets up the pattern as shown in Fig. 2 (e) and the subsequent pulses BCD produce similar patterns as shown except for a reversal of the arrows. If only one pulse B or C occurs intermediate A and D then the D pulse reverses the flux around only one of the outer apertures and there is no flux reversal in the waisted portions linking the output windings, this occurring during the following cycle coincident with the A pulse, Fig. 3 (a) to (e) (not shown). The output of the comparator is connected to one input of an AND gate the other input of which is supplied directly by D pulses so that an output from the gate only appears during coincidence of the two pulses, Fig. 4 (not shown). If the comparator operates on positive and negative pulses the output from the comparator is applied in common to two AND gates, the other inputs of which are supplied by D pulses and each gate being arranged to respond to either a positive or negative pulse. The resultant output pulses are then applied through pulsestretching circuits to the two inputs of an AND gate which gives an output when there is coincidence of inputs from the pulse-stretching circuits, Fig. 5 (not shown).

Abstract: 1,241,456. Fuel elements. GENERAL ELECTRIC CO. 13 Dec., 1968 [15 Dec., 1967], No. 59521/68. Heading G6C. A nuclear fuel element assembly comprises fuel elements arranged in a plurality of groups including an inner group and at least one outer group arranged concentrically around the inner group, the fuel of the elements of a first one of the groups having an initial predetermined enrichment of fissile Pu, and the initial Pu content (if any) of the fuel of the other or at least one other group being markedly different from that of the first. The Pu may be concentrated in the outer fuel elements of the assembly near the regions of highest neutron moderation, i.e. near zones of lowest thermal neutron energy, which arrangement provides for optimization of fuel cycle costs and fuel reliability. Alternatively, the Pu may be concentrated in the inner fuel elements of the assembly, which arrnagement provides for optimization of power and critical heat flux shaping by taking advantage of the increase in the ratio of the thermal fission cross-section of fissile Pu to that of fissile and of the unique higher heat flux capability of the central fuel elements of a boiling water reactor fuel assembly. In the first of these two embodiments, the outer fuel elements contain 1 to 2 atom per cent fissile Pu mixed with depleted or natural U of 0.25 to 0À71 atom per cent fissile U content, while the inner fuel elements contain U fuel of about 3 atom per cent fissile U content. In the second embodiment, the inner fuel elements contain 1 to 2 atom per cent fissile Pu mixed with U of 0À3 to 2 atom per cent fissile U content, while the outer fuel elements contain U fuel of 2 to 3 atom per cent fissile U content.
