Title: Improvements in and relating to electromagnetic switching devices for protecting electric power systems
IPC: H01H71/44
Filed: 1946-01-02
Abstract: 605,657. Electromagnetic switches; protective cut-out arrangements; snap-action switches. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 2, 1946, No. 170. Convention date, Jan. 4, 1945. [Class 38 (v)] On fault in a system 60, the coil 5 of an electromagnetic switch is energized to close contacts 1, 2 and short-circuit the system so that.the fault, if transient, will clear, a second switch 3, 4 is rapidly closed to short-circuit the coil, so re-opening the contacts 1, 2 and removing the short-circuit on system 60, the fault, if permanent, being thereby removed at interrupter 62 before the switch 3, 4 opens a predetermined time after. The downward closing movement of contact 2 causes a roller 30 to rotate a lever 22 clockwise about pivot 16 so as to strain a spring 29 and compress a spring 27 tending to close the contact-carrying member 15 which is held by a latch 17. Near the end of the stroke of contact 2, a roller 21 trips the latch 17, whereupon contact 4 closes with a snap-action, thereby short-circuiting the coil 5 and allowing a spring 13 to re-open contacts 1, 2. If the fault is of a transient nature, it will by now have been cleared. The lever 22 is held in closed position by a projection 37 thereon engaging a latch 36, which is released, to allow 3, 4 to open, after a time-delay, by an escapement mechanism 49, 54 driven through a ratchet-and-pawl device 50, 51 by a spring 47, which is energized through gearing 40 ... 42 when a pin 56 on the carrier 8 of the contact 2 rotates an arm 55 on gear 40 during closure of contact 2. The delay permits operation of a circuit-breaker 62 if the fault is persistent. The apparatus is enclosed in an oil-filled insulator having a window for observing an indicator 57. The application of the invention to a three-phase system is set out, Fig. 4 (not shown).

Title: Improved process for the stabilization of polyamides
IPC: C08G69/02
Filed: 1954-01-04
Abstract: 756,384. Polyamides. PERFOGIT SOC. PER AZIONI. Jan. 4, 1954 [Jan. 12, 1953], No. 175/54. Class 2 (5). In the preparation of polyamides by the polycondensation or polymerization of diamines and dicarboxylic acids or esters thereof, or of aminoacids, or of cyclic amides, the molecular weight of the product is controlled by carrying out the process in the presence of butyrolactone. Polyamides specified are polymers of omegaaminoundecanoic acid, caprolactam or hexamethylene diamine adipate. It is preferred to operate under such conditions that butyrolactone is not lost by distillation and this may be done either by adding the butyrolactone after the greater amount of water, if any, formed during polymerization has been driven off, or, and preferably, by forming a precondensate of the butyrolactone with a part of the polyamideforming starting material and employing this precondensate in place of butyrolactone. Specification 495,790, [Group IV], is referred to.

Title: Improvements in vehicle brake operating mechanism
IPC: B60T7/10
Filed: 1931-01-03
Abstract: 366,243. Hand-operated brakes. LEYLAND MOTORS, Ltd. and HAWORTH, H. F., Motor Works, Hough Lane, Leyland, Lancashire. Jan. 3, 1931, No. 303. [Class 103 (i).] Brake-operating mechanism particularly for motor vehicles comprises a hand-lever formed in two parts 7, 8 hinged together, a drum 6 co-axial with the lever pivot and connected to the brake mechanism, and a hand brake 9 surrounding the drum and adapted to be tightened or loosened to connect the lever to or disconnect it from the brake mechanism, by the rocking of one part of the lever relative to the other. The brake mechanism is operated by a shaft 2, Fig. 2, having a boss 3, loose on which is the lever 7 and to which are bolted ratchet wheels 4, 5 the latter having formed upon it the drum 6. The ends of the band 9 are connected, one end 10 adjustably, to the lower end of the lever 8. A spring 12 keeps the band in tension and the lever 8 pressed clockwise relatively to the lever 7. Clockwise movement of the lever 8 causes the band 9 to grip and the brake to be applied and held on by a spring-pressed detent 17 engaging the ratchet wheels 4, 5. The brake may be further applied by moving the lever anticlockwise to disengage the band and when the lever 8 engages an adjustable stop 13 on the lever 7, the levers move as one back to their original position. The lever 8 is then moved forward again to operate the brake mechanism further. The lever 8 is provided with a trigger 14 connected to the detent 17 by a lover 16 and a rod 15 pivotally mounted in alignment with the axis of the shaft 2. To release the brake the lever 8 is moved forward to take the reaction of the brake mechanism and to allow the detent 17 to rise on the ratchet, the detent 17 is released by the trigger 14, and the brake can now be released gradualiy by hand. A tailpiece 19 on the lever 7 eventually engages a stop 20, stopping the lever 7, the lever 8 may now be moved slightly back to allow the drum 6 to slip through the band, releasing the brake gently.

Title: Improvements in or relating to polyurethanes
Inventor: PHILLIPS LESLIE NATHAN
IPC: C08G18/22
Filed: 1958-01-03
Abstract: A polyurethane adduct comprises a hydrolysable salt of antimony as a storage stabilizing and cross-linking cure accelerating agent. ("Polyurethane adducts" are the reaction products of diisocyanates and polyols).  Antimony chlorides, particularly trichloride and perchloride, are especially advantageous.  In the examples the adduct is prepared by reacting a polyethylene glycol/neopentyl glycol/adipate alkyd resin in turn with naphthalene diisocyanate and toluylene diisocyanate dissolved in toluene and dichlorobenzene. Films were prepared by adding antimony perchloride and trichloride in methyl ethyl ketone and glycol mono-ethyl ether acetate respectively to portions of the adduct and allowing to stand at room temperature followed, in the latter case, by curing at 80 DEG C.  Samples of the adduct and antimony compound kept in bottles developed only a surface skin of resin, the bulk remaining liquid.  Without the antimony compound a gel-like mass resulted.  Specifications 858,096 and 872,568 are referred to.

Title: Improvements in or relating to machine-tools
IPC: B23G1/16
Filed: 1956-01-05
Abstract: 794,222. Screwing and tapping-machines. HAUSER SOC. ANON., H. Jan. 5, 1956 [Sept. 5, 1955], No. 383/56. Class 83 (3). A machine-tool, e.g. a screw-cutting-machine, comprises a slide 7, Fig. 1, movable against a spring 11 in a cross-slide 10 mounted on a frame 1, by a lever 15. The tool-spindle 19 carries, e.g. a tap, is slidable in the slide and centred by springs 45, 46, and is driven by a belt 22 passing over a pulley 21 fixed to a drum 26 on a shaft 24 having a pinion 25 meshing with a quadrant 29, Fig. 2. The quadrant is fixed to a pivot 30 supporting an arm 31 having a roller 32 engaging a cam 4 which is keyed to a shaft 2, together with a worm-wheel 5 and cam 6. Wheel 5 is driven by a worm on the spindle 8 of an electric motor 9, and cam 6 actuates a follower 18 to pivot the lever 15. When motor 9 is switched on to start a cycle of operations, the feed of slide 7 is performed according to the shape of cam 6, and the roller 32 passes from the level surface 35 on to the slope 36, causing arm 31 to turn and quadrant 29 to drive pinion 25 as weight 28 falls. Thus the tool-spindle is driven at a speed determined by the weight until the follower reaches a flat surface 37 or the quadrant abuts an adjustable stop 34. When the follower engages up-slope 38, the quadrant rotates the pinion-and-shaft in the reverse direction, thus winding-up the weight and turning spindle 19 in the opposite direction. The position of stop 34 determines the length of screw-thread cut.

Abstract: 431,400. Filters. WORSSAM & SON, Ltd., G. J., and FOX, R. H. S., Wenlock Road, City Road, and WEINREB, F., 16, Devonshire Square, Bishopsgate, both in London. Jan. 6, 1934, No. 575. [Class 46] A filter 1, which is mounted on horizontal trunnions so that it can be turned over by worm gear 9 to discharge the solid matter, has stoneware linings 2, 4 and a perforated false bottom 3 also of stoneware. The stoneware parts are clamped together by iron castings 6. The lining 2 forms a filtrate trough and may be arranged to slope from either side and towards one end. A filter cloth or other filtering medium is arranged over the part 3. One of the trunnions 11, Fig. 3, is hollow and forms a housing for a duct 13 lined with stoneware. The end of the duct is closed by the stoneware lining of an end plate 17 which is held in position by bolts 21 with encircling springs 24. Between the end of the duct 13 and the lining 16 is a stoneware valve member 14 with a port 15 therethrough, which when the filter is in position for filtering connects the trough 2 to a passage 18 leading to a filtrate receiver under vacuum. With the filter in the same position the member 14 can be turned to bring the port 15 into position so that it makes connection through a passage 19 to a similar receiver for wash liquor. When the filter is turned over to discharge the solid matter the member 14 moves with it and the port 15 is brought opposite a passage 20 through which compressed air is supplied to dislodge the solid matter from the filter. By means of a projection 14a and a fixed abutment the member 14 is automatically reset as the filter is brought back to the filtering position. Two filters may be arranged back to back with floors sloping in opposite directions and valves arranged so that one is in use while solid matter is being ejected from the other.
