Title: An improved automatic weft replenishing device for looms for weaving
IPC: D03D45/20
Filed: 1930-03-11
Abstract: 349,675. Changing bobbins &c. automatically in loom shuttles. CAMPS, J. P., 80, Colomer Street, Sabadell, Spain. March 11, 1930, No. 7857. [Class 142 (iii).] The transfer bobbin is dropped from a stationary magazine into a bobbin conveyer which moves with the lay and transferrer during bobbin transfer. The transfer mechanism includes the usual transfer hammer 1 pivotally mounted on the loom frame and operated, when a spindle A is rocked on indication of weft failure, by the engagement of the catch 9 of a lever 7 with a projection 16 on the lay, pivotal connection being established between the lever 7 and the hammer by means of a stud 8. The lever 7 is in addition pivotally connected by means of a link 4 and pins 5, 6 to a bobbin or weft carrier conveyer 17 pivoted at 14 to a stationary magazine and provided at its lower end with a compartment to hold a single bobbin. During the normal working of the loom the parts are positioned as shown in the drawing, but on weft replenishment being required, the spindle A is rocked and a slotted lever 12 thereon engages a pin 11 on the lever 7 causing the latter to be moved about the spindle 8 and into the path of the projection 16. This movement of the lever 7 also causes the conveyer 17, through the link 4, to rock about its pivot 14 to the position shown in dotted lines thereby positioning the fresh cop below the weft hammer ready for transfer. As the sley advances, the projection 16 engages the catch 9 and forces the lever 7 backwards in a horizontal direction with the result that the conveyer is caused to follow the movement of the sley whilst the hammer 1 is caused to swing about its pivot 10 to effect transfer.

Title: Improved Multiple Control Apparatus for Electric Railways with Motor-driven Main Switch Drums.
IPC: B60L15/34
Filed: 1919-04-01
Abstract: 126,278. Akt.-Ges. Brown, Boveri, et Cie. May 3, 1918, [Convention date]. Master control systems.-In a multiple control apparatus with motor-driven controllers, each controller and each automatic cut-out device for the pilot motors has two contact surfaces insulated from each other and connected to opposite poles of the supply. The master controller has a reverser k interlocked with the control drum i in the usual manner and the drum i has two stepped segments m, n, and fixed contacts so arranged that, in the on positions, the segment m is connected to the positive lead and the segment n is connected to the negative lead. The pilot motor a drives the shaft e of the motor controller through a slip coupling c, and also drives a cut-out device which, in the form shown, consists of brushes u, v mounted on a screw spindle to slide over contact bars x, y. The pilot motor field-coils are controlled for reversal by a relay g, and the locking- magnet r controls the switch s of the motor a. If the master controller drum i is rotated to position III, the leads 1, 2, 3 are connected to the positive side and the leads 4, 5, 6 to the negative side. The right-hand coils of the relays g, h are energized ; this energizes the field coil p of the motor a, removes the pawl t from the notched disk w, and operates the switch s to close the circuit. The motor runs to operate the controller spindle e and the screw spindle of the device l. As soon as the brush v leaves the contact 1, the relays g, h are de-energized. The relay o remains closed but the relay h is returned to its off position by a spring. The pawl t, however, is on the rim of the disk w and the switch s is held closed until the disk w has completed a revolution and the brush v is on the contact 2. This action is repeated until the brush v reaches the contact 4. when it is connected to the negative side and the motion stops. Similar action occurs when the controller is returned to its zero position, but the controlling-current passes through the brush u instead of the brush v.

Title: Process for producing char and volatile products from coal
Inventor: GRIFFITHS DAVID MORGAN LUTHER
IPC: C10B47/18
Filed: 1963-03-01
Abstract: An improvement in the process of Specification 1,027,331 for producing unsaturated hydrocarbons of low molecular weight from coal resides in heating the coal particles to a temperature of 1300-2000 DEG  C. in the closed zone for a total residence time of less than 125 milliseconds.  Higher yields of acetylene, e.g. up to 28% based on the weight of coal, are thus obtained, in addition to CO, H2 and CH4. Preferably the residence time of the coal particles in the zone, including the time of heating to the reaction temperature, is up to 100 milliseconds and that of the gaseous products 0.01-25 milliseconds, the hydrocarbons then being cooled to below 300 DEG  C. within 0.01-25 milliseconds.  The particles are preferably carried by a stream of preheated hydrogen.  The zone pressure may be 2 mm. Hg-15 atmospheres.  The coal may be of 20-350 B.S.S. size, or "micronized," i.e. less than 30 microns, and of Rank 300-900; if desired, cannel or brown coals or lignites can be used.

Abstract: 798,044. Lipstick holders. ROTHSCHILD, A. G. DE, ROTHSCHILD, E. L. DE, ROTHSCHILD, L. D. DE, and ROTHSCHILDS CONSTRUCTION, Ltd., [trading as ROTHSCHILD & SONS, N. M.]. Jan. 31 1957 [March 16, 1956], No. 8382/56. Class 18. A lipstick holder comprising an axially-slotted inner tube 1 having a yielding stop 10, 11, an helically slotted scroll tube 13, an outer tube 20 and a holding cup 24 with a projection 25, has near the upper end of the scroll tube an edge surface 15 forming a circumferential extension of the helical slot, below the projection 25 when the latter has been moved enough to overcome the yielding stop. The inner tube 1 is closed at the lower end by a flanged finger knob 2, the wall of the flange 3 being slit and bent at tongue 5 which projects into annular space 4, and it has an axial slot 6 with a flared open upper end 7 ; it also has a limited secondary slot 8 with its upper end merging with a circumferential slot 9 entering the main slot 6 so that a spring leaf 10 is formed having a hook 11, the leaf 10 and hook 11 together constituting the yielding stop ; a tongue 12 with a downwardly facing lip 19 is punched near the free end in the wall of the tube. Surrounding the inner tube is the scroll tube 13, which has a helical slot 14 open at each end, and a circumferential edge surface 15 at one side of its upper end extending to an axially directed stop edge 17, and a rectangular aperture 18 punched in its wall. The tube 13 is mounted on the tube 1 by screwing it past the tongue 12 so that it is retained by engagement of its free end beneath the lip 19, and is surrounded by the outer tube 20 of which the lower end is located in the annular space 4 ; being provided with a tongue 22 to abut the tongue 5 and a rectangular depression 21 in its wall to register with the aperture 18, and having a slot 23 formed in the beading at its upper edge. The axially projecting pin 25 of the cup 24 engages in the axial slot 6 and the scroll slot 14. Normally the projection of the holding cup is limited through engagement of the projection 25 with the projection 11 on the spring leaf 10 ; when the cup is to be replaced, the tube 1 is rotated forcefully relative to the tubes 13 and 20 so that the projection 25 overcomes the yielding stop 10, 11 and rides along the edge surface 15 until it reaches the stop edge 17, after which the cup may be lifted out. Accidental re-entry of the cup into the holder is prevented by the engagement of the projection 25 with the edge surface 15.

Abstract: 1535376 Colour television SANYO ELECTRIC CO Ltd 3 March 1976 [5 March 1975] 08578/76 Heading H4F The invention relates to a drop out compensator for a colour sequential video signal read out from a video disc. As described, filters 15, 16 separate all the high and low frequency components respectively of the luminance signal, the red, green and blue colour signals having been sequentially superimposed in the low frequency band. Simultaneous colour signals are made available at synthesizer 24 using two one line delay lines 21, 22 so that if a red signal is input to the first delay then blue and green signals are available at the outputs of the first and second delay respectively. Synthesizer 24 generates the low frequency component of the luminance signal which component is recombined with the high frequency component at 19. A third delay line 30 provides a signal of the same colour as is input to the first delay line so that when a drop out is detected at 40 and contact 20a moves to terminal 20c, the same colour signal from three lines previous is substituted for the present signal for the duration of the drop out. The three colour signals are also fed to a trisequential switch 25 which, in combination with demodulator 34 and matrix 35, is used to produce colour difference signals which are modulated on a subcarrier at 36. The chroma signal so produced is combined with the luminance signal and sync signals at 38 and 39 respectively. In an alternative embodiment, Fig. 2, not shown, the input to the first delay line is the sum of the present signal and the delayed signal from the third delay line, the sum being attenuated by 6dB. In addition the AM modulator occurs before the switch 20.
