Title: Improvements in or relating to the protection of rotating electrical devices
IPC: H02H7/125
Filed: 1959-07-27
Abstract: 864,639. Protective arrangements. WESTINGHOUSE ELECTRIC CORPORATION. July 27, 1959 [Aug. 1, 1958], No. 25631/59. Class 38 (5). [Also in Groups XXXV and XXXVI] Rotatably mounted rectifiers 26 in the field circuit of a turbo generator are protected by fuses 30 in a wheel which rotates with the rectifiers. The rectifiers, e.g. of silicon type, are arranged for three-phase, full-wave operation and, in general, there are several elements in parallel in each limb of the circuit, each with its own fuse. Thus, failure of one or a few elements is not catastrophic; they are disconnected by their fuses and their share of the load is taken by the remainder. In parallel with each fuse is an indicator 32, either a lamp or a fusible wire, or the fuses themselves may give an indication when blown. The wheel in which they are mounted is recessed to allow stroboscopic viewing of the indicator.

IPC: G01S13/28
Filed: 1960-07-25
Abstract: 959,374. Pulse radar; pulse signalling. ETAT FRANCAIS. July 25, 1960, No. 25883/60. Drawings to Specification. Headings H4D and H4L. In a radar pulse system the transmitted pulses are extended and the received pulses contracted by means of a modulator and filter circuit. After modulation, the upper side band is removed and the signal applied to a filter having a propogation time decreasing with increasing signal frequency. If the received pulses are modulated from a high to a low frequency the arrangement first produces a signal which is modulated from a low to a high frequency and secondly, applies this signal to a filter of the above type which effects compression. The effect of jamming is reduced by the selection of the frequency bands employed.

Title: Reclaiming polymeric siloxane scrap
Inventor: MCCOWAN WILLIAM ARCHIBALD
Filed: 1950-10-26
Abstract: Cured polymeric, particularly elastomeric, siloxane scrap is reclaimed by heating at 200-350 DEG  C. in an oxygen-free atmosphere in the presence of steam.  Superheated steam is preferable since the pressure may then be atmospheric.  The scrap should be in a divided condition to provide ready access for the steam and the treatment is continued until the scrap has been softened to the desired extent, e.g. from 15 minutes to 2 hours.  The reclaimed scrap may be milled with fresh uncured material and moulded into articles.  Several examples are given of the reclaiming of various cured commercial siloxane rubbers using an atmosphere of superheated steam at atmospheric pressure and temperatures ranging from 200 to 302 DEG  C. for 15 or 30 minutes.  The products were compounded with various quantities of fresh uncured material, moulded and used.  The mechanical properties of the products are compared with those of products from 100 per cent. fresh material.

Abstract: 902,971. Automatic couplings with transition gear. USINES EMILE HENRICOT S.A. July 30, 1959 [Aug. 14, 1958], No. 26206/58. Class 103(5). An automatic coupling having a knuckle pivoted at 7 and provided with known ledges such as 16 and 17 which co-operate with lugs on the wings 9, 10 so as to relieve the pin of buffing and draw loads, has arcuate lugs 22, 23 on top and bottom portions of the knuckle tail which co-operate with ledges 24, 26, and surfaces 25, 27 in the head casting. Tolerances are arranged so that corresponding lugs and ledges make contact successively when proceeding from the tail of the knuckle to the pivot. By arranging the lugs and ledges 22-27 as shown in Figs. 2, 4 and 5, the line of action of the draft force may be directed along a line 37 through the centre of ledge 26 to the root of the. draw bar 3 and not through the pin 7 in a direction parallel to the draw bar, thus reducing stress in the knuckle. Conversely, however, as the angle α increases, the lock and the wings of the coupler will be more heavily loaded. The knuckle .5 may also be provided with a tail end 28 adapted to catch behind a further lug on the head casting, and the knuckle may be shaped to engage a ledge on the lock 11, Fig. 6 (not shown). The lock 11, Fig. 7, has a ledge 42 which engages in the locking position beneath a ridge 43 on the head casting to prevent unintentional unlocking, and the lock lifter 41 is also provided with a head 44 adapted to engage a ledge 45 if the lifter should jump upwardly in operation. A transition gear, Figs. 9, 10 and 11 (not shown), is also provided, and employs an internally and externally oppositely screw threaded tube containing a screwed rod. The tube at one end screws into a nut pivoted to a shackle, and the other or remote end of the screwed rod is pivoted to a casting journalled in a pocket below the knuckle. A handle is provided for rotating the tube and varying the length of the gear, which gear in operation extends through a cut in the buffing face 4 of the head.

Filed: 1930-09-08
Abstract: 358,228. Time switches ; snap-action switches. RHODES, Inc., M. H., 185, Church Street, New Haven, Connecticut, U.S.A. Sept. 8, 1930, No. 26840. Convention date, Sept. 6, 1929. [Class 38 (v).] A switch with time delay mechanism which may be used or not as required has two handles 3, 8. When the timing handle 8 is " off," operation of the switch handle 3 serves to move the switch rapidly on and off in a normal manner. When the handle 8 is " on," movement of the switch handle 3 into one position, say into its " on " position serves to close the switch rapidly, but the switch is then automatically latched and if the handle 3 is then returned to its " off position, the switch will only open after a predetermined time. The length of time may be increased by reciprocating the handle 3 a determined number of times before finally leaving it "off." With the handle 8 "off," operation of the handle or dolly 3 carries a compression spring 45, arranged between the lower end of the dolly and a member 4, over dead-centres, the member 4 then being driven about an axis 67 and its lower end, which moves in a slot 24 in a slide 61, hitting the end of the slot and driving the slide 61 and contacts 11 carried by it into or out of bridging engagement with fixed contacts 59, 60. When the handle 8 is " on," and the dolly 3 is moved " on," the member 4 is held latched in the position shown in Fig. 3 by a projection 72 on the member 4 engaging a latch 9 which has been moved into latching position by the handle 8 acting through an intermediate dead-centre spring 47. If the dolly 3 is now moved " off " the parts occupy the position shown in Fig. 3, and the arm 4 remains latched till after the time interval the latch 9 is moved out of position by a projection 84 on a wheel 13, Fig. 9. The wheel 13 is fixed to a ratchet wheel 18 and when the dolly 3 is reciprocated a spring- pressed pawl 7 on it engages and drives the ratchet wheel till the projection 84 has moved round through an angle dependent on the number of reciprocations. A spring is simultaneously wound up. The wheel 13 is prevented from return movement under the action of the spring by its fingers 77, Fig. 9, engaging holes 76 in a gear wheel 19, Fig. 8, which is prevented from rotating by being connected through a train of gearing with an escapement wheel 22 the anchor 82 of which is held fast by a spring-pressed bell crank lever 12 so long as the dolly 3 is "on." When the dolly 3 is moved " off " a portion 83 on it engages the bell crank 12 and releases the anchor so that the clockwork begins to run down and after the predetermined time the projection 84 on the wheel 13 releases the latch 9 and allows the arm 4 to move to open the switch. An indicating disc mounted on the same shaft as the wheel 13 shows the length of time still to run.
