Abstract: 581,879. Bearings. SKEFKO BALL BEARING CO., Ltd., and LAMM, A. M. April 27, 1945, No. 10657. [Class 12 (i)] A ball or roller bearing mounting comprises a resilient disc-like web 32 in which the bearing is mounted with its axis normal to the web by means of tongues 31 extending laterally from the web to engage frictionally across the cylindrical periphery of the outer race 30 of the bearing. The disc-like web is dished and when screwed on to a casing 23 exerts end pressure on the race 30 by a cup-like dust-excluding cover 42 secured as by rivets to the web and arranged around the shaft and engaging the side face of the race 30. Alternatively the web may have short tongues to engage the side of the race, Fig. 5, (not shown), or a washer of metal or plastics material with short tongues projecting into the spaces between the laterally extending tongues of the web may be inserted against the side face of the race, Figs. 1 and 4 (not shown). A dust excluder 76 may be gripped between a shoulder on the shaft and the inner race 29. Fig. 12 shows an arrangement in which two oppositely acting resilient webs 32 with their laterally extending tongues 31 interdigitated bear on the cylindrical periphery of the outer race 58 of a roller bearing and also press flat short-tongued washers 60 against the side faces of the outer race such washers incidentally retaining the rollers 56 in position. The rollers bear directly on the shaft 57. The area of the disc-like web is apertured to increase the resilience.

Abstract: 841,555. Automatic exchange systems. POSTMASTER GENERAL. July 13, 1956 [April 14, 1955], No. 10829/55. Class 40 (4). Two-way communication between two circuits X1, X2 of a group of such circuits is effected by providing each circuit with an integrating circuit WF1, WF2 and a switch S1 S2 connecting them to a common point H which in turn may be connected by a switch SL to one of a further group of integrating circuits CL, the switches S1 and SL being synchronously closed at one instant in a recurring cycle for mutual interchange of energy between WF1 and CL, and the switches S2 and SL being synchronously closed at another instant in the cycle for mutual interchange of energy between WF2 and CL. The recurrence frequency of the closure of switches S1 and S2 must be at least twice the frequency of the signals emitted from the sources X1, X2. The switches may be electronic gates pulsed by sources connected to the switches, Fig. 3 (not shown), or by sources connected in series with condensers C1, C2 of the integrating circuits. For improved transfer of energy inductances may be connected between the integrating circuits and their respective switches, the period of closure of the switches being half the resonance period of the circuits so formed. The condensers of the integrating circuits may be removed and low-velocity cable may either directly replace the condensers of the integrating circuits, or be inserted between the inductors and the switches. Fig. 7 illustrates an extension of the arrangement in which members of two such groups may be connected together, each group being provided with a common point H1, H2 connectable to the integrating circuit CL by switches SL1, SL2 which may be operated (in conjunction with an S-switch in each group) at different instants in the cycle. A suitable low impedance pulse source for the above embodiments may comprise a normally saturated inductor driven by a pulse on an input winding to the non-saturated state, thereby pulsing an output winding, Fig. 4 (not shown). The Provisional Specification describes an arrangement, Fig. 8, in which switches are connected in a closed loop. The voltage sources V1, V2 normally bias the rectifiers MR1, MR2 to conduction so that the outputs of the filters (or integrating circuits) WF1, WF2 are shortcircuited. If GX1 and GX2 are pulsed simultaneously the rectifiers are back-biased thereby effecting connection between the filters. Since in this case the inducatances L1, L2 of the filters are adjacent the switches, additional shunt capacities C1, C11 forming resonant circuits with the inductances may be provided, the half-resonant period being equal to the pulse period so that complete transfer of energy may be effected.

Abstract: 436,396. Uniting by fusion. MUREX WELDING PROCESSES, Ltd., and PATERSON, J. H., Ferry Lane Works, Forest Road, Walthamstow, London. April 10, 1934, No. 10839. [Class 83 (iv)] A flux-coated welding rod for automatic arc welding has one or more longitudinal fins 5 which project through the coating to provide metallic surfaces to meet sliding or rolling electric contacts for conducting the welding current to the core 6. The fins may be integral with the core or may be soldered or spot or otherwise welded thereto, preferably through a flange 7. The feed rolls 1, 2 engage the fin. The flanges may be perforated to engage feed rolls formed with projections. The rods are coated with flux by dipping or extrusion after the fins are formed on or attached to the core, so that a greater part of the width of the fin is left exposed. In order that long lengths of rod may be coiled, the fins may be interrupted at intervals or the rod may be in separate lengths connected by a continuous fin or fins. The fins may be made of metal the same as that of the core or may be of aluminium, particularly when the core is of iron. The fin metal is for the most part burnt away, and if desired may be cut or torn away after passing through the contacts.

Abstract: 854,441. Controlling gas burners. SIMON-CARVES Ltd. April 1, 1958 [April 3, 1957], No. 10857/57. Class 75(1). In a carbonization plant heated alternately by a rich fuel gas and a lean fuel gas, a cock 31 controlling the rich fuel gas and two cocks 41, 51 controlling two supplies of lean fuel gas are mechanically interlocked by cams 33, 43, 53 and pivoted pawls 34, 44, 54, the pawls being connected to fluid operated lock jacks 37, 47, 57 in such manner that the opening of the rich fuel gas cock 31 is prevented unless both the lean fuel gas cocks 41, 51 are closed and vice versa, the lock jacks however not preventing the closing of any of the cocks. The fluid for actuating the lock jacks is supplied under pressure by a pump 2 from a tank 1 and is controlled by a selector valve 4 comprising a piston 6 having annular recesses 7, 10, 12, 13, the recesses 7, 10, 13 being connected by radial bores 8, 11, 14 and a central bore 9. Each lock jack comprises a recessed piston 35 connected to its pawl 34 and urged by a spring 36 to hold the pawl in engagement with the corresponding cam 33. In Fig. 1 the rich fuel gas cock 31 is open and the lean fuel gas cocks 41, 51 are closed and are prevented from opening by the pawls 44, 54 engaging shoulders 42, 52 on the cams 43, 53. The selector valve 4 has been positioned to allow a change in firing from rich to lean fuel gas. When the rich fuel gas cock 31 is manually closed the pawl 34 is moved by lock jack spring 36 into engagement with the shoulder 32 on the cam 33 and piston 35 of the lock jack 37 displaces fluid in the top of the lock jack 37 through pipe 27, recess 58, pipe 29, recess 48, pipe 22, pipe 21, connector 17 on selector valve 4, recess 10, radial bore 11, central bore 9, radial bore 8 recess 7 and pipes 23, 24 to supply tank 1. Pressure fluid from pump 2 then passes through pipe 3, connector 16 on selector valve 4, recess 12, connector 15, pipe 19, pipe 20, recess 38 in piston 35, pipe 30 into the top of lock jack 57 and through pipe 28 into the top of lock jack 47. Pistons 55, 45 are thus depressed by fluid pressure to move their pawls away from the shoulders of the cams so that both lean fuel gas cocks can be opened.

Title: Creased and shaped washable garments and method of manufacture thereof
Inventor: WEIL HENRY BERNARD
IPC: D06M15/423
Filed: 1965-03-15
Abstract: Garments of any style, size, design and shape which are press free with sharp imparted creases retained therein after repeated washing are produced by impregnating a fabric, e.g. a fabric comprising cotton and viscose rayon fibres alone or in admixture with polyester fibres, with an aqueous solution of a composition containing a thermosetting compound containing a catalyst possessing the property of maintaining the thermosetting compound in stable equilibrium in the fabric for periods ranging up to one year at temperature below the curing temperature of the compound, the impregnation being controlled to an extent that 85-100% of the compound by weight is retained in the fabric, drying the fabric at a temperature below the setting temperature of the thermosetting compound to an extent that 8-10% by weight of moisture is retained therein, cutting the fabric containing the thermosetting compound in an unset state to the size, shape, style and design of the desired garments, sewing the fabric to provide garment seams, finishing the cut and sewn fabric to completed garments, imparting at least one crease in each of the garments, presetting the garments at the areas of the seams and creases, and finally curing the thermosetting compound to a water-insoluble state. The thermosetting compound may be an imidazolidone prepared by reaching formaldehyde, urea and glyoxal or other aldehyde at an acid pH and having the formula <FORM:1106223/D1-D2/1> in which at least one X is a hydroxy group and R's may be hydrogen and the catalyst may be zinc nitrate or magnesium chloride.  The solution is preferably constantly agitated at 120 DEG F-130 DEG F, the fabric dried at 200 DEG -220 DEG F presetting effected at 275 DEG -285 DEG F or 300 DEG -310 DEG F depending upon the type of fabric treated and curing effected at 340 DEG -380 DEG F.  If dimethylolated imidazolidone is used and setting effected at 325 DEG -350 DEG F the fabric may also be rendered shrink-resistant.  Cotton stretch fabrics, obtained for example by a slack mercerization process, may be treated.  The solution may also contain wetting agents and softeners, e.g. polyvinyl alcohol and polyethylene.

Title: Improvements in or relating to variable speed power transmission apparatus
IPC: F16D67/00
Filed: 1932-04-16
Abstract: 402,395. Hydro-mechanical variablespeed gearing. HICKS, SIR M., 12, Grosvenor Gardens, and HEATH, A. R. N., Rowans, Hartington Road, Chiswick, both in London. April 16, 1932, Nos. 10929 and 10940. [Class 80 (ii).] The invention comprises a differential gear train, two elements of which are driven through hydraulic transmitters or clutches of the kind in which slip is possible, such as R, S, the third gear element, preferably a planet-carrying spider such as D, being fast on a driven shaft B. When both clutches R, S are operative, the gear elements turn all in the same direction. Different speeds are effected by engaging the clutches alternatively and simultaneously, and by allowing varying amounts of slip. In the arrangement shown, the hydraulic clutches are of the kind described in Specification 401,371 in which there are clutch plates alternately on the driving and driven members, such plates rotating clear of one another and driving by the viscosity of liquid between the plates and held out around the annular clutch chamber by centrifugal force. The clutch R makes connection between a drum C fast on a driving-shaft A and the annulus E of a first epicyclic train. Supported on the spider D are planet gears D<1> which mesh with the annulus E and with a sun gear F fast on a sleeve G prevented from rotating backwards by a spring-pressed detent ring B<3>. Thus, when the clutch R is operative alone, the shaft B is driven at a middle speed by the planets D<1> rolling round on the held sun F. The clutch S similarly drives the annulus H of a second train the planets D<2> of which are supported on a loose carrier E<1> secured to the annulus E. The sun gear F<1> of the second train is also fast on the detent sleeve G. When the clutch S is operative alone, the planets D<2> roll around on the held sun F<1> so as to drive the annulus E more slowly than before, so that the shaft B is driven at a low speed. When the clutches R, S are both operative, the gear turns solid, yielding a high speed, the sleeve G overrunning the detent B<3>. The clutches R, S are separated by a partition J and by packing. Normally liquid is held in both clutches by centrifugal force so that both clutches are operative. To render the clutch R operative alone, the liquid is blown out of the other clutch S so as to free the plates there by pressure air admitted by a duct N<2>. The expelled liquid piles up in an annular chamber N<1> with a vent N'. The clutch S is rendered operative alone by blowing the liquid out of the other clutch R by admitting pressure air through a long duct L<2>. The expelled liquid piles up in a chamber L<1> with a vent L<4>. The ducts N', L<2> terminate in ports N<5>, L<5> so that control of the gearing as a whole is effected by the axial displacement of a slide valve O which delivers pressure air at O<1>. A chamber O<2> beyond the valve O is exhausted by a through duct O<2>.

Abstract: 1359634 Pulse radar COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL 10 April 1956 [19 April 1955] 10960/56 Heading H4D To render systematic jamming of a radar system more difficult the transmitted frequency is varied in a random manner. The output from a fixed frequency (1500 Mc/s) oscillator 1 is mixed at 3 with that from an oscillator 2 having a varying frequency, amplified at 9 and transmitted. The signal received is amplified at 19 and mixed with the output from the pulsed oscillator 2 at 5. The resultant signal passes through a resonant cavity 6 tuned to 1500 Mc/s and then is mixed at 7 with a 1530 Mc/s output from an oscillator 8, the required intermediate frequency of 30 Mc/s then being available for utilization. The frequency of the oscillator 8 is maintained by comparison at 11 with oscillator 1. The random change of frequency at 2 is produced by the use of a backward wave travelling wave tube.
