Title: Improvements in and relating to dynamo-electric machines
IPC: H02K27/02
Filed: 1943-01-15
Abstract: 606,100. Quadruplex windings. BRITISH THOMSON-HOUSTON CO., Ltd., and LANE, A. C. Jan. 15, 1943, No. 758. [Class 35]  To avoid unbalanced voltages in the four armature circuits of an A.C. commutator motor having a fully - pitched quadruplex armature winding, the slotted armature core comprises sections a, b separated by an axially extending gap d, whereby the coil sides of the winding may have laterally displaced portions located in different slots in the two sections of the core. The coil shapes are such that any coil winding progresses forwardly through each of four slot positions in traversing the four slots in which the coil is located. Thus, in the winding shown in Fig. 1, for an armature having 3 commutator segments per slot, the coil m connected between segments c1 and c5 occupies position No. 1 in slot s1 of core section a, position No. 2 in slot s1 of core section b, position No. 3 in slot s (n+ 1) in core section b (where n is the number of slots per pole) and position No. 4 in slot s (n + 1) in core section a, the last position being actually position No. 1 in slot s (n, + 2), as in this case there are only three positions per slot; Circuits n, p and q follow similarly to circuit m, but are displaced therefrom by one, two and three slot positions, respectively. Equalizing conductors may join any segment to any point in any circuit which is at the same potential, thus the point x of circuit m may be joined to segment c3 of circuit p while the point y of circuit p may be joined to segment c4 of circuit q. Alternatively, the circuits may be coupled by a duplex winding and/or a simplex winding, and the Specification includes rules as to the pitch and location of these windings in relation to the quadruplex winding. Fig. 2 shows a quadruplex winding for a machine having 4 segments per slot and 12 slots per pole, the circuits m, n, p, q being coupled by a duplex winding k1 and a simplex winding j.

Title: Improvements in or relating to photographic processing
IPC: G03C7/00
Filed: 1947-01-09
Abstract: 620,219. Photographic processes. HORNER, R. G., and ILFORD, Ltd. Jan. 9, 1947, No. 773. [Class 98 (ii)] A method of exposing one side only of a radiation-sensitive material consists in directing radiation on to the material while immersed in a liquid absorbing the radiation, the depth of liquid between the material and the source of radiation being small compared with its depth on the other side of the material. The material may be a colour film with a blue-sensitive emulsion layer separated from layers sensitized to other colours by a yellow filter layer, which blue-sensitive layer is to be exposed to blue light without exposing the other layers. The material is placed in a tank having a glass window and filled with a liquid absorbing blue light, such as Tartrazine dye. The blue light is directed through the window on to the film, of which the blue-sensitive layer faces the window arid is at a short distance from it. Light passing the edges of the film has to pass through a greater depth of dye and is absorbed. Preferably, there is no space between the dye and the window, and the inner surface of the tank absorbs blue light.

Title: Improvements in or relating to the formation of n-diaryl dithiocarbamates of metals
Filed: 1936-01-10
Abstract: Metal salts of diarylthiocarbamic acids are prepared by the action of carbon bisulphide on metal compounds of diarylamines. The term diarylamines includes all secondary amines in which the amino group is linked directly to two aromatic nuclei, the specified diarylamines being diphenylamine, phenyltolylamines, phenylcumylamines, phenylxenylamines, phenylnaphthylamines, phenylanthracylamines, ditolylamines, dixenylamines, dinaphthylamines, phenylar - tetrahydronaphthylamines, di-ar-tetrahydronaphthylamines, carbazole, o-iminodibenzyl, ms-ms-dimethylacridane, and thiodiphenylamine; diarylamines containing substituents, e.g. halogen atoms or nitro, alkoxy, aryloxy or secondary or tertiary amino groups may also be used. The metal compounds of the diarylamines may be prepared (1) by heating the diarylamine with a metal in the presence or absence of a catalyst, which may be iodine or a salt of iron, cobalt or copper, or (2) by heating the diarylamine with a metal amide or nitride.  The alkali and alkaline earth metals, including magnesium, are the preferred metals.  The reaction of diarylamine metal compound with carbon bisulphide is preferably effected in a solvent, e.g. a hydrocarbon or an excess of amine.  In the examples: (1) diphenylamine is boiled under reflux with sodium and the product is treated at about 90 DEG  C. with carbon bisulphide after addition of benzene; sodium diphenyldithiocarbamate is obtained; (2) diphenylamine containing a trace of iodine is boiled under reflux with magnesium and the product is treated with carbon bisulphide after dilution with benzene; magnesium diphenyldithiocarbamate is obtained; (3) phenyl - b  - naphthylamine is heated with sodamide and the product is treated with carbon bisulphide; sodium phenyl-b -naphthyldithiocarbamate is obtained.  The products may be subjected to double decomposition to convert them into salts of other metals, e.g. zinc or lead, or they may be acidified to yield the free acids. They may also be converted into esters by reaction with halogenated hydrocarbons, or into mixed anhydrides by reaction with acid halides, or into thiuram disulphides by oxidation, or into thiuram polysulphides by reaction with sulphur chloride.

Filed: 1989-01-06
Abstract: PURPOSE:To obtain the high-magnetic-flux-density steel sheet by specifying the time from the start of rough rolling to that of finish rolling and the finishing temp. at the time of obtaining a non-oriented magnetic steel plate of the Mid-Si class by continuous casting. CONSTITUTION:The continuously cast ingot obtained from the molten steel contg., by weight, <=0.02% C, 1.0-3.0% Si, 0.1-1.0% Mn, <=1.0% Al, and the balance Fe is heated to 1000-1250 deg.C, rough-rolled, and finish-rolled to obtain a hot-rolled steel sheet. One cold rolling and final annealing are then applied in accordance with the conventional method to obtain a non-oriented magnetic steel plate. In this method, the time from the start of rough rolling to that of finish rolling is controlled to Xsec in the equation. Consequently, the ridging of the product is prevented. The succeeding finish rolling is finished at the high-temp. region of 750-900 deg.C. By this method, the aggregate structure governing the orientation of the hot-rolled plate is improved, hot-rolled plate annealing can be omitted, and the magnetic flux density is increased.

Filed: 1991-01-09
Abstract: PURPOSE:To reduce the horizontal component of force to cause the slipping out of a locking roller for its reliable locking by forming a locking device of a locked part provided to incline obliquely downward, and a lock lever having a locking part being detachable to the locked part from a obliquely lower side. CONSTITUTION:When a lock lever 41 is rotated in a locking direction 80, a rotary shaft 38 rotates in the longitudinal direction, and a locking member 49 interlocks with the shaft 38 to rotate in an engaging direction 81, and an locking roller 55 is engaged in the engaging groove 60 of a locked plate 50 from a obliquely lower side, and the locking member 49 abuts on a bolt 53 to control its rotation. An arm member 24 is therefore locked. The lock lever 41 and the locking member 49 take an oblique posture, and a spring 48 energizes the lever 41 in the locking direction 80. When a shock acts onto a device in this state to make horizontal external force F1 in a slipping out direction 82 act on the locking roller 55, since the central axis 83 of the roller 55 intersects a vertical axis 84 passing a rotational axis center 47 at an angle alpha, the external force F1 turns into cosine component force F1cosalpha, and is lessened to make the slipping out of the roller 55 difficult.

Title: Floating type optical head driving mechanism
Inventor: YOSHIZAWA TAKASHI
IPC: G11B21/21
Filed: 1989-01-05
Abstract: PURPOSE:To highly accurately control a rotating operation and floating head translational operation without interfering to each other by independently controlling the rotating operation in the floating surface of a slider and the floating head translational operation in the parallel direction of an information track. CONSTITUTION:A slider 2 is attached to one edge of a slider holding member 4, and the other edge of the slider holding member 4 is rigidly attached to a rotating member 5. The rotating member 5 fits to an axis member 7 rigidly coupled to a fixing member 6, and the member 5 can vertically move and rotates. The rotation driving around the axis member 7 of the rotating member 5 is executed by utilizing electromagnetic force generated among a coil 52 fixed to the rotating member 5, a permanent magnet 65 loaded on the fixed member 6, and a magnetic substance 66. That is, the floating head rotating operation on the floating surface of the slider 2 and the floating head translational operation in the parallel direction of the information track can be independently controlled. Thus, since both driving operations do not interfere to each other, they can be highly accurately controlled.
