Title: Improvements in or relating to the treatment of dyeings prepared on cellulose materials by means of substantive dyestuffs
IPC: D06P1/645
Filed: 1934-06-01
Abstract: Substantive dyes, dyeing with.--The fastness, especially the fastness to water, acids and moist ironing, of dyeings prepared with substantive dyestuffs on cellulosic materials, is increased by after-treating such dyeings with solutions of mixtures of polymeric ethylenediamines of the general formula <FORM:0440488/IV/1> together with compounds of the general formula (C2H4.NH)n, the mixtures containing substantial proportions of compounds in which n is greater than 2, in the form of their salts with inorganic or organic acids or in admixture with such acids.  In an example, a cotton yarn, dyed with Sirius blue BR, is treated for 20 minutes with a solution containing formic acid and the residue of a mixture of polymeric ethylenediamines obtained by the action of ammonia upon an ethylene-1 : 2-dihalide (cf. Specification 337,368, [Class 2 (iii)], from which the fraction boiling under 10 mm. pressure up to 220 DEG  C. has been distilled off, and the treated yarn is rinsed. Specification 435,388 also is referred to.

Filed: 1917-11-09
Abstract: 117,015. British Thomson - Houston Co., (General Electric Co.). Nov. 9, 1917. Lubricant conveyed by mechanical means.-A ball bearing is lubricated by a loose ring 19 which hangs on the end of the shaft 5 and delivers oil to a pocket 25, whence it flows through the bearing 12. The ring 19 lies in an eccentric recess 26 in an extension 23 of an end cap 21. The part 23 rests on a ledge 24 on a bracket 10 which supports the bearing. A groove 29 leads oil to the pocket 25, and an opening 30 allows oil dripping from the end of the shaft to return to the reservoir 18. By turning the cap 21, the ring 19 is raised from the shaft and can then be withdrawn through the opening 20.

Title: Graphic plotting system
IPC: B25H7/04
Filed: 1974-04-16
Abstract: 1462515 Automatic control GERBER  SCIENTIFIC INSTRUMENT CO 16 April 1974 [20 April 1973 9 July 1973] 16463/74 Heading G3N A graphic plotting system consists of a drawing table 42, a carriage 48 movable over the table, a cursor 46 mounted on but movable relative to the carriage, means for detecting displacement of the cursor relative to the carriage, and means responsive to the detection to drive the carriage so as to eliminate the cursor-carriage displacement, whereby the carriage automatically follows the cursor. Electric signals representing such carriage displacements may be fed to a computer 32 which can subsequently or simultaneously command the same or another like carriage to reproduce the displacements. Hence an operator can make the cursor follow a sketch drawing and a pen or pens 49 on the carriage or carriages can automatically produce one or more precise drawings. In Fig. 2, the carriage 48 is movable in the Y direction along a member which is itself supported at its ends by carriages 50 conjointly movable in the X direction. The cursor 46 is mounted on a plate which has a pivotal connection 112, Fig. 3, with a member 416 Fig. 8 (not shown) which is itself pivotally mounted on the carriage 48. Hence the cursor can move a limited distance in the XY plane. The member 416 carries, at its end opposite the cursor, a 4-quadrant photosensor 110 exposed to a light source 118 which is fixed relative to the carriage 48. The outputs from the quadrants Q1- Q4 are used to establish X and Y co-ordinates of sensor-carriage displacement in the form of X and Y outputs which drive the carriages 50 and 48 and which may also be registered in a computer 32. The carriage-driving signals may be fed directly from the cursor circuit 60 as shown in Fig. 2, or via the computer. In either case, the computer may control one or more further drawing tables. A multipletable system, linked to a common computer, may have, at some of the input stations, an electronic cursor system in which a mechanical cursor 203 Fig. 9 (not shown) can be moved over the screen of a CRT 202 Fig. 6 (not shown) on which an XY grid is displayed, the cursor movements being detected by X and Y transducers whose outputs are fed to the computer for use as control data for the drawing table or tables of the system.

Abstract: 588,285. Indicating - tops or teetotums. INNES, C. J. BARTON-. June 29, 1945, No. 16644. [Class 132 (ii)] A top comprises a body portion 1 having a projection 2 on which the top can spin, a spindle 3 having a knurled head 4 by which the top can be spun, and a disclike member 5 loosely mounted on the spindle and having teeth-likeserrations 6 which engage with similar serrations 7 on the -top of the body. The upper surface of the body 1 bears a number of indications, such as numerals, letters &c. one of which is rendered visible through an aperture 8 when the top is at rest. When the top is spun, the sudden twist imparted thereto causes the serration 5 or teeth 6 on the disc 5 to disengage from the serrations 7 on the top of the body 1, leaving the disc 5 to spin for a time free of the body portion and at a different speed. The disc 5 may be provided with vanes or the like 11 to assist in retarding its speed. The number of teeth on the body and disc portions may be equal in number to the indications on the body and the indications may be a direction for moving a piece in a game. The upper surface of the body 1 may be provided with a number of spaced projections 9 around its periphery to receive a plate 10 having a castelated periphery so that the plate may be prevented, during spinning of the top, from movement with respect to the body portion. The same top may thus be utilized for playing different games. The top may be used as a toy or as a substitute for dice &c. in games, deciding order of play, or in raffles &c.

Abstract: 1456450 Control of AC motors H-F GUELDENER 17 April 1974 [17 April 1973] 16754/74 Heading H2J An asynchronous motor 2 is driven or braked according to the position of switches 10, 11 and 12, which are simultaneously controlled by a common actuating element 1 movable between an operating and a braking position corresponding to the following circuit conditions:- (1) Switch 10 closed to energize the stator windings 3, 4, 5 from a three phase supply RST, switch 11 open and switch 12 changed over to charge a capacitor 13 through a rectifier 6 and resistor 14 from the voltage between phase R and the neutral MP. (2) Switch 10 open, switch 11 closed to connect the rectifier 6 in parallel with the stator windings 3, 4 and switch 12 changed over to discharge the capacitor 13 through resistors 14, 15, 16 and a relay coil 8, whose contacts 9 close to connect the windings 3, 4 to the supply R, MP through a rectifier 7. The windings 3, 4 thus receive two half-wave rectified currents which are phase displaced by 180 degrees and thus combine to produce a smoothed D.C. braking current, whose component produced by rectifier 6 falls to zero as the induced voltage in windings 3, 4 reduces with decreasing motor speed. Adjustable resistor 15 is set so that the coil 8 is de-energized and contacts 9 open just after the motor has stopped, the component of braking current produced by the rectifier 7 thus being maintained for a time which may be varied according to the motor characteristics and the load to be braked. The described embodiment may be modified as follows:- (1) Members 7, 9 are replaced by a thyristor (37) whose firing current is made or broken by contacts (39) controlled by a relay coil (38), Fig. 2 (not shown). (2) Members 7, 9 are replaced by a thyristor (67) having a control current generator (79) adjustable to a desired pulse width to produce a desired mains component of braking current, the supply to the generator being taken from the supply R, MP through contacts (69) controlled by a relay coil (68), Fig. 3 (not shown).
