Abstract: 670,791. Mounting electric motors. ENGLISH ELECTRIC CO., Ltd. June 30, 1950 [May 20, 1949], No. 13511/49. Class 79 (iii). In an axle-hung electric traction motor wherein the motor casing is built up, the suspension bearings are carried by integral extensions of the motor frame and plates. As shown, the motor casing is built up from formed plates welded together along axially extending seams to form a box having integral axially extending lugs 2 which engage corresponding notches in the end plates 4, to which they are welded. Extensions 4a of the end plates carry housings 9 for roller bearing suspension, end caps 10 and bolts 11 secure the housings 9. With this construction the welded joints do not carry the weight of the motor. The other side of the motor may be supported from a frame cross member 18 by links 19 and a bar 16 notched into and welded to the motor end plates 4. The axle is driven from the motor armature through a reduction gear housed in the casing 15.

Inventor: NEIER RHEINHARD
IPC: C09B62/535
Filed: 1963-04-05
Abstract: The invention comprises heterogeneous cobalt complex compounds containing monoazo dyes, one of the said monoazo dyes being of the formula <FORM:1037773/C4-C5/1> wherein X represents hydrogen, halogen, alkyl or alkoxy and the NH2 group is in the adjacent position to the -N = N- group and the other monoazo dye being a member of the ortho, ortho1-dihydroxy - benzene - azonapthalene series, and cobalt, less than two cobalt atoms being in complex combination with two molecules of monoazo compound.

The ends of the arms 13 are coupled by links so that they are oscillated in unison. In a modification, the bars 11 are each mounted on the bottom of a pendulum lever, all the levers being oscillated in unison by a crank mechanism. The holes in each bar are so spaced that as the bar passes over the plants some are left untouched by the liquid.

Title: Improvements in Thyristor Trigger Circuits
Inventor: ECCLES ARNAUD MICHAEL
IPC: H02M1/088
Filed: 1966-03-29
Abstract: 1,165,326. Triggering thyristors. ENGLISH ELECTRIC CO. Ltd. 28 March, 1967 [29 March, 1966], No. 13899/66. Heading H2F. [Also in Division H3] A trigger circuit for a thyristor e.g. 4 comprises a D.C. source 18 for charging a transmission line 25 and switching means 36 for discharging the line into the primary winding 12 of a transformer, the secondary winding of which is connected between the gate and cathode of the thyristor 4, the primary winding 12 being terminated at 29 by the characteristic impedance of the line 25. A plurality of thyristors may be connected in series with each other and a load 3 across an A.C. source 1, 2 and energized simultaneously by winding 12 common to the ferrite core transformers 10 individual to the thyristors. Components 5-8 and 11 protect the thyristors against excessive voltage and current. The voltage applied to line 25 is stabilized by Zener diodes 23, 24. To discharge the line, thyristor 36 is rendered conductive by a pulse at 38, or a beam of e.g. light, if responsive to radiation, thus causing Shockley diode 27 to break down and allow energy to pass from line 25 to winding 12 and trigger thyristors 4. Shockley diode 27 may be replaced by a further thyristor which is rendered conductive by a pulse on its gate from the cathode of thyristor 36 when thyristor 36 is triggered. A number of the trigger circuits as shown may be connected with all the thyristors and a common load connected across an A.C. source. In such case, a winding 39 on one of the transformers in each circuit may be used to supply a trigger pulse to the gate 38 of the thyristor 36 in the following circuit. Thus it is then only necessary to trigger the thyristor 36 in one circuit, from an external source, for all circuits to be triggered, in cascade.

Title: Improvements in or relating to the manufacture of artificial teeth
IPC: A61C13/08
Filed: 1925-05-27
Abstract: 254,075. Jackson, W. J. Mellersh-, (Dentists' Supply Co.). May 27, 1925. Teeth, artificial. - Artificial teeth are formed by first moulding a portion thereof from porcelain material, between hard surfaces, and then moulding between a hard surface and the surface of the already moulded material the balance of the porcelain material required to complete the tooth structure, and heating to vitrify the two parts, into a unitary porcelain tooth. In one form, Figs. 4 - - 6. part 16 of the porcelain material is formed between moulds 3, 12, to give a tooth portion tapering from the incisal to the cervical end, and is then dried by heating the moulds. The body portion 11<a>. which is made from porcelain material 11 of darker tint, is then moulded between the surface of this portion 16 and a third mould 2, Fig. 5, the moulds 2, 3 being clamped together. Anchor elements 10 may be embedded in the body material and holes 9<a> for the pins provided, or the pins may be directly moulded in the material without the separate anchors, or holes or depressions without anchors or pins may be moulded therein. The moulds are heated to bake the material and the biscuited tooth then removed and converted into porcelain by heating to the required temperature, the parts 16 and 11<a> fusing and blending together. The moulds 2, 3, 12 may be formed to make several teeth simultaneouslv and are provided with registering pins 6 and sockets, and with contact surfaces 5, 5<a> which engage when the moulds are brought together. In another form, the third mould is adapted to form the body portion 11<a> first, the remaining portion of the tooth being moulded between this portion, in the mould 2. and the mould 3. The moulds 12 may also be constructed by having the parts 13, which are used to form the part 16, made on separate blocks 20, Fig. 11. These blocks may be registered correctly with mould part 3 and the mould body 12d then placed over the blocks 20 and attached thereto bv solder 22. In a further form, the third mould is dispensed with and blocks 13<d>, Figs. 9 and 10, are placed in mould 2 and have pins 18 registering with holes 19 in the mould, and the part 16 of the tooth is then formed by means of the moulds 2, 3. The block 13d is then removed, and posts and anchors and the body material 11 inserted in mould 2 and the formation of the tooth completed in the former way. The block 13d may be adapted to co-operate with mould 2 so that the body portion 11<a> is first formed.

Filed: 1927-05-25
Abstract: 293,533. Electrical Improvements, Ltd., and Logan, E. A. May 25, 1927. Mechanical cut-outs for overhead and like conductors.-A safety arrangement, for ensuring the cutting off from the supply of overhead conductors in case of breakage, consists in the employment of a pivoted conducting ring or frame attached and electrically connected to and supported by one power conductor and surrounding without normally touching another power conductor, the arrangement being such that breakage of either conductor establishes contact between a conductor and its surrounding frame so producing disconnection of the supply. As shown, in Figs. 1 and 2, the lower earthed conductor A<1> carries a conducting arm D<1> terminating in a frame D surrounding the upper insulated conductor A. The arm D<1> is pivoted to the apex of a triangular frame F (Fig. 3) mounted pivotally on the post B so that if the conductor A' is broken the frame F is moved around its pivot and the conducting frame D brought down into contact with the conductor A. Any breakage of the conductor A causes the portion passing through the frame D to drop into contact therewith. Similar arrangements are described (Figs. 4 and 6, not shown) for lines placed side by side, horizontally. Where, as shown in Fig. 9, an earthed line A<1> of a three phase supply is mounted horizontally between insulated lines A, A<2> a frame D<5> is provided around the outer lines, being suspended from the centre line by a wire E<1> and pivoted by arms F<2> about a rod F'. In a modified form of this arrangement shown in Fig. 8 the line A is surrounded by a frame D arranged as already described with reference to Fig. 1, and the line A<2> is surrounded by a frame D<2> clamped to the earthed framework B<5>, B<6>.
