Abstract: 334,583. Michaneck, T., and Sõchsische Webstuhlfabrik. Oct. 5, 1928, [Convention date]. Shuttles, changing bobbins and the like in, automatically.-In order that bobbin changing mechanism may be used in looms having shuttle change boxes at both sides, a special ejector cell a, Fig. 3, is provided at the change side where the bobbin changing device is situated, this cell being at no time at the level of the shuttle race. When a shuttle is substantially exhausted, feeler mechanism f causes the bobbin changing device to be operated, this operation being timed to occur when the spent shuttle has been picked into the upper shuttle-box at the change side and these boxes have been raised to their upper position. The ejected bobbin passes into the cell a and is guided out of it by surfaces l. The invention is shown applied to a loom having three shuttles 1 to 3, which are picked in succession for weft mixing purposes by moving the shuttle boxes as shown in Fig. 2. The bobbin feeler may be at either side, but if it is situated at the non-change side, it is preferably operated at every fourth pick, as shown at x<1> - - x<3>, by means driven from the pulley z of the pattern cards controlling the shuttle change box motion, the feeler mechanism operating a counter which causes the bobbin changing device to be operated three picks later as shown at y<1> - - y<3>. Weft of various colours may be used, a multi-colour bobbin holder being then employed controlled by the change box motion pattern cards. The bobbin feeler may be at the change side.

IPC: H01H71/44
Filed: 1945-07-10
Abstract: 595,931. Electromagnetic switches. BRITISH THOMSON-HOUSTON CO., Ltd. July 10, 1945, No. 17540. Convention date, July 13, 1944. [Class 38(v)] [Also in Group XXXV] An electromagnets device which operates with a time delay and which can be used to actuate a switch, cir cuit breaker &c. is provided with an arm ature consisting of small magnetic ele ments such as smal balls which are en closed in a tubular body which restricts the movement of the elements as t h e y move from their normal position of rest under the influence of a surrounding energised coil. Fig. 2 shows a device comprising a coil 1 wound on a spool 2 and enclosed in a magnetic casing 4 which is split longitudinally to reduce eddy current effects. The winding may be surrounded by a clamp the ends of which pass through the slit in the casing and are clamped by a bolt 6 to mounting brackets 7 fixed to the casing. Within the spool 2 is a tubular body 13 containing a number of magnetisable elements 12. The upper and lower ends of the body 13 are of cylindrical shape and of different diameters and are connected by a tapered portion which delays the movement of the elements 12 in an upward direction when the coil 1 is energised. At the upper end of the device is a pole piece 3 within which is a slidable member 8 carrying a rod 27 which is pushed upwardly by a rider 25 resting on the elements 12 when the coil 1 is energised. The timing of the device may be varied by raising and lowering the tubular body 13 which is fastened to a cap 15 having a sliding fit on a member 17 attached to the lower end of the spool 2. In order to maintain a fixed travel for the member 8 for varying adjustments of the cap 15 and body 13 the upper end of the tube 13 is secured to a screw-threaded member 14 which engages threads on the interior of the polepiece 3 and the rod 27 is screwed into the operating member 8. Lugs 28 on the rod 27 prevent the latter from turning in the member 14 and the threads on the rod 27 are of the same pitch as the threads on the member 14. When the cap 15 is turned and so raised or lowered the rod 27 moves vertically through the same distance. Movement of the member 8 rocks a pivoted bar 30 which may be a trip latch on a circuit breaker operating mechanism.

Abstract: 827,917. Automatic control systems. SOC. ALSACIENNE DE REGLAGE THERMIQUE S. ar.l. June 4, 1958 [June 5, 1957; June 7, 1957], No. 17788/58. Class 38 (4). In a system for automatically maintaining a variable at a desired value, deviations of the variable alter a resistance B, Fig. 1, controlling the resultant signal applied to the primary of a step-up transformer A the output of which is applied, in opposition to the higher mains voltage 1, 2, through a rectifier II to one winding E2 of a differential relay RP. The other relay winding E1 is energized through a rectifier I from the mains in series with a rheostat P3 which serves to set the desired value. Current in relay winding E1 is stabilized by a non-linear resistor V. Change-over contacts of relay RP control the energization of a motor or power switch M which operates to correct the variable. Stabilization is provided by signalling lamps L1, L2 which are also switched by relay RP and which heat temperature-variable resistances T1, T2 in series with the relay windings to introduce negative feedback. In a modification both temperature variable resistances are associated with relay winding E1, one being in series and the other in shunt. Volt-drops in resistors R1, R2 produced by the lamp currents provide feed-back to ensure positive operation of relay RP. These resistors may also be heated by the lamps so that their effect is less when contacts open. A.C. operation of relay RP is referred to.

Filed: 1918-11-01
Abstract: 130,856. Sheldon, P. Nov. 1, 1918. Junction-pieces and the like; butt joints.-For correcting flange adjustments in faulty steam &c. pipes, the spaces between two flanges which do not meet correctly are filled by means of a filling piece formed of two wedge-shaped members A, B, which can be rotated relatively to one another to cause the member to fit accurately between the faulty flanges. Micrometer scales on the sides or edges of the disks enable the exact position of the two wedges to be reproduced in a workshop if the members A, B are taken there to be connected together and fitted with packing pieces. The members may, however, be connected by bending a flange C on the member A into an undercut groove in the member B. Holes or projections may be formed in the edges to facilitate adjustment, and the two members may be secured together by a short tube which is bent into undercut grooves in both members A, B; or an external ring may be similarly employed. Two wedge-shaped members as A, B may be connected by a solid rivet, and be formed with passages for the flow of fluid.
