Abstract: 1,012,911. Transformers. FOSTER TRANSFORMERS Ltd., and T. COURTNEY. Sept. 4, 1963 [Sept. 4, 1962], No. 33819/62. Heading H1T. In a tap-changing system smooth voltage transition is obtained between adjacent tapping studs 6 of the main transformer winding 5 by inclusion in the connections to the load circuit of auxiliary windings 12 and 13 the voltage of which is bucked or boosted by voltages obtained from contacts 11 moving over at least one winding 10 of a toroidally wound auto-transformer fed by another auxiliary winding 8 on the main transformer. The brushes 11 are mechanically linked to the main tapping contacts 7 and when the latter are on the same tapping stud (e.g. the end stud), the brushes 11 are in contact with opposite ends of the winding 11 and each carry half the load current. From this position one brush 11 moves over an insulated track (shown as a dashed line semi-circle) disconnecting from the load circuit its associated main tapping contact 7 which can them make off-load connection with the next contact stud 6. The other brush 11 picks up from winding 10 a voltage which diminishes to zero as the brush 11 reaches the centre of winding 10 and then increases in the opposed direction, this voltage opposing or adding to the voltage of the winding 12 or 13 connected to that brush in dependence on the position of the latter. The brushes may engage additional short end portions of a higher resistivity wire when engaging or leaving the winding (Fig. 4, not shown). There may be two auto-transformer windings 10 fed in parallel by the centre-tapped winding 8 on the main transformer 5 (Fig. 2, not shown) and having moving contacts 11 connected in parallel with one another and in series with the windings 12 or 13 on the main transformer. In another arrangement the windings of two fine switch transformers 91, 92 (Fig. 3, not shown) are in series but have their output circuits in parallel.

Filed: 1922-12-18
Abstract: 191,020. New Departure Manufacturing Co., (Assignees of Simmons, C. B.). Dec. 27, 1921, [Convention date]. Back-pedalling brake and free-wheel arrangements. - Relates to coaster brakes in which a rotatable axle constituting the driving - member is mounted inside a driven member such as the wheel hub and of the kind in which an axially-moving clutch-sleeve is used to engage the driving-member with the driven member and to actuate a brake. The clutch-sleeve 12, Fig. 1, is moved by a pin 16, driven through axle 3 to which pedal cranks 4 are secured. The ends of the pin engage a coarse thread on the interior surface of the clutch-sleeve and so on forward movement of the cranks move it into engagement with clutch teeth 13 on the hub and on back-pedalling cause it to actuate a brake. This brake comprises plates 23 having interior fingers slidably received in longitudinal slots in the sleeve 18 on the brake-anchor 6 and alternate plates 24 having exterior fingers fitting in longitudinal slots in the hub shell: the disc 29 at one end is thicker and has clutch teeth 30 to engage clutch teeth 14 on the clutchsleeve 12. The disc at the other end of the brake abuts against a shoulder 19 on the brake anchor 6 which is held against rotation by an arm 33 secured to a frame member 2 by a'clamp 38, Fig. 7. The arm passes over a threaded boss 20 on the brake anchor, projections 35 engaging in recesses in the anchor and being held by a lock-nut 39. The interior opening of the boss 20 is enlarged so as to present a shoulder 22 which engages semi-circular pieces of wire 31 fitting in a peripheral channel about the crank-shaft 3. A lag spring 50 is received in a groove around the clutch-sleeve 12 and' has a hump 52 fitting in one of the longitudinal slots in the hub shell. The axle 3 is swaged at one portion on opposite sides so as to form projections on which threads 42 are cut, as shown in Fig. 8. Washer 44 between cone 5 and lock-nut 47 is shaped to fit over these projections as shown in Fig. 9. The axle 3 is mounted in ball-bearings 40 in the frame members and washer 41 takes up any space between this bearing and the crank 4. In the modification shown in Fig. 10, a clutch-sleeve 120 is tapered at each end and coacts with clutch socket 71 on the hub on forward-pedalling and on backpedalling forces brake segments 230 upon a tapered brake anchor 260 and spreads them into braking contact with the hub 70. A split ring 231 retracts the brake segments. An extension 123 of the clutch-sleeve causes lag of the clutchsleeve. The brake segments have lugs 250 sliding in longitudinal slots in the anchor 260; separation of the segments from the anchor is prevented by a split ring 61 in a peripheral groove on the anchor. An arm 330 fits over a reduced portion 62 of the brake anchor, which is made non- circular by having straight parts on it and this arm is secured to a frame member 20 by a strap 331 passing through an eye 332. Sleeves 310, 313 surround the crank-shaft at each end.

Title: A process and apparatus for the manufacture of rods and other elongated articles from artificial resin
IPC: B29C48/475
Filed: 1934-12-06
Abstract: In the method claimed in the parent Specification, the combination of the individual sections produced at each stroke of the plunger is effected by joining surfaces which are not, or not entirely, the smooth faces produced by the plunger.  To this end, the smooth faces may be lacerated or destroyed as by a pin or wedge inside the mould or the sections may be moved relatively to each other.  The relative movement may be produced by reducing the cross-section of the mould at a point where permanent combination is still not effected.  Thus, for making cylindrical rods, the plunger may be of greater cross-section than that of the rod and a conical constriction may be formed in the mould.
