Title: Improvements in or relating to phase conversion of electrical energy
IPC: H01F30/14
Filed: 1948-03-02
Abstract: 647,435. Phase changing. BUTLER, F. March 2, 1948, No. 6584. [Class 38 (ii)] In a system providing single to polyphase conversion and vice versa, and of the kind comprising a capacitive reactance connected with an inductive reactance, maintenance of the phase voltages and displacement with variation in load current and supply voltage is effected by saturable reactors which in the case of single to three-phase and vice versa are included in the two reactive branches each consisting of a saturable reactor L1, L2 and condenser C1, C2, in parallel, predominantly capacitive and inductive respectively. The D.C. windings L1b on the reactor included in the predominantlycapacitive branch is supplied with D.C. related to the load current, whilst the opposing D.C. windings L2b and L2c on the reactor L2 forming the predominantly inductive branch are supplied with D.C. related respectively to the load current and supply voltage such that the net D.C. excitation of reactor L2 at full load is zero and the inductive reactance is maintained equal to the capacitative reactance. The D.C. is obtained through rectifiers B2 and B1 connected respectively either direct or through transformers in a load or supply lead and across two leads of the supply or load. The inductive and capacitive branches may be connected in series across two phase leads as shown, with the third phase connected to the junction of the branches, or included in two of the three phase supply or load leads (Figs. 2 and 3, not shown). Various modifications are described, whereby adjustable taps may be provided on the reactor windings. The condensers may be variable, fixed or variable resistors may be associated with each rectifier so as to afford control of the reactors. According to the Provisional Specification the arrangement compensates for changes due to variation in supply frequency.

Title: Improvements in circular knitting machines
IPC: D04B9/06
Filed: 1946-03-04
Abstract: 629,249. Knitting-machines. FIDELITY MACHINE CO., Inc. March 4, 1946, No. 6669. Convention date, Sept. 23, 1943. [Class 74 (ii)] To permit of rib knitting, without the use of take-up weights, the dial needles 2 are made straight; and each is maintained in position in its slot by a bowed strip-metal " presser " 1, having at its outer end a loop holding-down finger 4. The finger is advanced to overlie the dial loop, during transfer to a cylinder needle 6, and prevents that needle, if misaligned, from so lifting the loop that it could be caught on the point of the dial needle latch 5, or pass over it and be caught on the dial needle hook; the edge 4a constrains the outwardlymoving loop to pass under the free end of and close the dial needle latch. Bevel 4c provides clearance for the inward passage of the loop and directs it under the finger; shoulder 4b limits inward movement of the loop; bevel 4d eliminates a corner on which the loop might catch and prevents it becoming pinched between the adjacent faces of " presser " and needle. The dial needles are formed with concavities 13.

Patent GB-1278220-A (GB)
Title: Indicating circuit
Inventor: LEWELYN ROGER
IPC: G06F12/123
Filed: 1971-03-13
Abstract: 1278220 Data storage INTERNATIONAL BUSINESS MACHINES CORP 13 March 1971 6816/71 Addition to 1161930 Heading G4C The least recently accessed of a plurality of storage registers is indicated by an indicating circuit. The invention is a modification of parent Specification. For an 8 register store an array of bistables as shown in Figure 1 is used; every time a register (e.g. 3) is accessed its associated row of bistables (Ad, Bd, Cd, Dd) is set to 1 and its associated column of bi-stables (Ea. Eb, Ec) is set to 0. Thus the least recently accessed (LRA) register is that whose row is 0 and whose column is 1, i.e. register 6 in Fig. 1. First embodiment (Fig. 1).-The bi-stables are divided into groups P, Q, R representing the 4, 2, 1 code. If P = Aa.Ab.AcAd + Ba.Bb.Bc.Bd ... Da.Db.Dc.Dd= 1 then LRA is 4, 5, 6 or 7, if P = 0 LRA is 0, 1, 2, 3. If Q = P (Ae.Af + Be.Bf) + P (Ea.Eb + Fa.Fb)=1, then LRA is 2, 3, 6 or 7, if Q=0 LRA is 0, 1, 4 or 5.  If R = P.Q.Ag + P.Q. Ce + P. Q.Ec = P. Q. Ga=1 then LRA is 1, 3, 5 or 7, if R=0 LRA is 0, 2, 4 or 6. Hence the LRA is defined by a unique combination of the values of P, Q, R, using known electronic circuitry i.e. if PQR = 0, LRA = 0 &c. P, Q, R use only one polarity signals from the bi-stables but the complements may be used instead. Second embodiment (Fig. 2, not shown).-The bi-stables are divided into a 5, 3, 2, 1 code and similar logic used. The equations in both embodiments are implemented using conventional circuitry and the P, Q, R signals may directly address a store. It is stated that Specification 1,161,930 is improved by avoiding resetting of the bistables on initial use and errors in the bi-stables.

Title: Improvements in or relating to electric circuit breakers
IPC: H01H73/24
Filed: 1953-03-12
Abstract: 777,810. Automatic circuit-breakers; switches held set and freed mechanically. CUTLER-HAMMER, Inc. March 12, 1953 [March 12, 1952], No. 6835/53. Class 38(5) A circuit-breaker comprises a metal strip 12 mounted on a terminal 29 and flexible in a vertical plane, a contact 44 and embodying a fluid-filled capsule as disclosed in Specification 774.513. Projections 52 on opposed walls of the capsule pivotally engage sockets 58 formed in legs 54, 56 of a member 50 which straddles the strip 12. Leg 54 is extended to form a reflex spring 39 which biases the strip 12 upwards to open the contacts 44. 46, but the spring is normally prevented from so acting by a keeper 43 on the soring which is retained by a cam surface 45 on the lower edge of a control lever 47 pivoted by a trunnion 67. In the closed position of the breaker (Figs. 1, 2) the part 39a of the spring below the keeper 43 is under compression and the part 39b above the keeper is under tension to create contact nressure. The legs 54, 56 are biased inwardly but are moved apart on expansion of the capsule due to an overload current flowing in the strip 12, such expansion moving the keeper 43 to the left (Fig. 2), so that it disengages the surface 45 and permits the spring part 39a to open the contacts. During the tripping action a cam follower 49a on the lower end of leg 56 slides over the flat inner surface 47a of the lever 47 and the top of the member 50 hits a surface 75 on the lever and rotates it to .a " trip " position to give visual indication. On collapse of the capsule the keeper 43 engages a laterally sloping surface 77 on the lever formed above the surface 45. To reclose the breaker the lever 47 is moved to the reset position (Fig. 5) whereupon the keeper 43 rides up the surface 77 and then snaps beneath a cam surface 79 forming a continuation of the surface 45; also the cam. follower 49a co-operates with a cam surface 51. Movement of the lever to the " on position causes stressing of the spring 39a due to the coaction of the surface 79 with the keeper 43 but closure of the contacts cannot take place until the follower 49a snaps into a notch 71 in the surface 51. The breaker may be manually opened by movement of the lever to the " off " position whereby the keeper 43 moves beyond the end 83 of the surface 45, reclosing being effected as previously described. Specification 777,809 also is referred to.

Abstract: 829,607. Clutch combinations. SULZER FRERES S.A. March 4, 1958 [March 5, 1957], No. 6921/58. Class 80 (2). [Also in Group XXXV] A fluid coupling is operated in parallel with a mechanical clutch to transmit starting power from an electrical machine used as a motor to a prime mover, and to transmit running power from the prime mover to the electrical machine used as an alternator. A machine 2, normally used as a synchronous condenser, is used to start the prime mover, which may be a gas turbine, by filling a fluid coupling 6 with oil. The speed of the prime mover is raised to a value at which it is self-sustaining and then raised further under its own power to synchronous speed. The clutch 5 (which may be a magnetic clutch) is then engaged and the prime mover drives the machine 2 as a generator. Other embodiments show the use of reduction gearing to reduce the torque transmitted by the fluid-coupling 6 and a further mechanical clutch (which may act as a freewheel) to allow the gearing to idle when the clutch 5 has been engaged. The gearing and further clutch may be combined in the form of an epicyclic transmission.

Inventor: WIEDEN HORST
IPC: C08G18/68
Filed: 1964-02-19
Abstract: Polyurethane fibres and filaments are produced by reacting a linear polyester containing hydroxyl groups with excess of an aromatic diisocyanate in the melt at above 100 DEG  C. and reacting the product obtained in solution in a polyacrylonitrile solvent at about 50 DEG  C. with such a quantity of a dihydroxyalkyl ether of a phenol or naphthol that the remaining excess of diisocyanate (calculated on 100 parts by weight, of polyester) is 0.2-3 parts by weight, and spinning the resulting solution wet or dry after being stored for several hours at or below room temperature.  The polyester may contain b , g  unsaturated ether groups in the side position, e.g. polyesters derived from allyloxysuccinic acid, glycerine monoallyl ether, trimethylol propane monoallyl ether, pentaerythritol dicrotonyl ether, or their alkoxylation products. Conventional aromatic diisocyanates are specified.  Dihydroxy alkyl ethers mentioned are: di - [p - (b  - hydroxyethoxy) - phenyl] ether, di - [p - (b  - hydroxyethoxy) - phenyl] sulphone, and naphthylene - 1,5 di - [b  - hydroxyethyl ether).  Solvents may be dimethyl formamide, dimethylacetamide, dimethyl sulphoxide and dimethoxydimethyl acetamide.  In a typical Example (1) a polyester derived from hexane 1,6-diol,2,2-dimethylpropane 1,3-diol and adipic acid was reacted with diphenylmethane 4,41-diisocyanate at 130 DEG  C.  A solution of p-(b ,b 1-dihydroxyethoxy)-benzene in dimethyl formamide was added and diluted with additional dimethyl formamide.  The solution was kept for 12-15 hours at 15-20 DEG  C. and wet spun in an aqueous bath.
