Patent GB-1545193-A (GB)
Title: Production of acid orthophosphoric acid ester mixtures
IPC: C11D3/36
Filed: 1977-10-03
Abstract: Mixtures of acid orthophosphoric esters are obtained when a phosphorus(V) oxide is reacted with a mixture of a monohydric alcohol and an alkanepolyol having 2 to 12 carbon atoms and 2 to 6 hydroxyl groups in a molar ratio of phosphorus(V) oxide to monohydric alcohol to alkanepolyol of 1:2:<4>/n where n is the number of hydroxyl groups in the alkanepolyol molecule, by mixing or kneading the reaction components at a temperature of between 0 DEG C and 120 DEG C in the presence of an inert gas with exclusion of moisture in the course of 1-6 hours. The mixtures of acid orthophosphoric esters of short-chain mixtures of monohydric alcohol and alkanepolyol are notable for a minimal corrosive effect on metals and they are therefore preferably used as constituents of acidic cleaning compositions. Products with long-chain radicals, if necessary after neutralisation with inorganic or organic bases, are suitable for use as emulsifiers, wetting agents, glidants antistats and foam regulators in detergents and cleaners. Halogen-containing products are useful intermediates for preparing flameproofing agents.

Abstract: 1367687 Nitriding by glow discharge ELEKTROPHYSIKALISCHE ANSTALT BERNHARD BERGHAUS 3 Sept 1971 [8 Sept 1970] 41264/71 Heading C7U Iron or steel are surface hardened by glow discharge in an atmosphere of treatment gas, particularly nitrogen or a titanium compound, in at least two stages, treatment of part of the surface being suppressed by shielding during at least one stage, so that a hardening element is diffused to differing depths. As particularly applied to a valve plunger Fig. 1, the body is treated by glow discharge nitriding in a first stage with the regions 3, 4, 5, 6 protected by shields 26, 27, 28, 29 which may be spaced up to 0À5 mm. from the surface, the treatment being effected at above 500‹ C and particularly for 18 hours at 530‹ C. The outer sleeve 26 is then removed and treatment continued for 6 hours at 490‹ C. In a modified second stage the ring 28 shielding region 4 may also be removed, while the inner sleeve 27 may be partially withdrawn to allow nitriding of that part of the inner surface adjacent to the closed end and thereby minimize distortion. Further improvement may also be obtained by shortening the outer sleeve 26 during the first stage.

Title: Improvements in and relating to self-locking core chucks
IPC: D01H7/16
Filed: 1961-11-21
Abstract: 951,156. Securing rollers on mandrels. A. T. BLAKE. Nov. 21, 1961, No. 41516/61. Heading F2U. A coupling device designed to lock the core of a roll of web material during winding and unwinding operations to a mandrel comprises a cylindrical chuck body 12 dimensioned to accommodate a core 13. Figs. 1, 2 and 3 show two opposite recesses 14 cut longitudinally into the chuck body 12, with the bottom of each recess terraced in the form of opposite stairs descending towards a common centre groove 5, Fig. 14. Inserted into these recesses are toothed rollers 15 having the same length as the chuck body, which fit closely but freely rotatably, between front and rear retaining rings 9 and 10 respectively. The rollers 15 are provided with neck journals 16, for the purpose of retaining the ends of peripheral springs 17 held within a groove 17<SP>1</SP> cut into the surface of the chuck body perpendicularly to its axis. The core chuck body 12 is locked to the mandrel shaft 11 by a set screw 25. Each roller has an overall diameter slightly in excess of the greatest depth of the recess 14 with one tooth resting on the bottom of the common centre groove 5 and an opposing tooth adapted to bite into the opposite face of the core 13, Fig. 3, to form a pivot point for a turning of the roller. The roller 15 is forced into ascending the stairs in a direction of the rotary movement of the core 13 or is forced to mount the stairs in the opposite direction of the rotary movement of the mandrel 11, depending whether the rotational movement originates with the core 13 or the mandrel 11. As a result, the uppermost tooth of the roller 15 digs into the core 13 to the extent of ascent upon the stairs and a substantially unbreakable contact between the core 13 and the mandrel 11 is produced. A slight rotational movement of either the core 13 or the mandrel 11 in the opposite direction causes the toothed roller 15 to descend into its rest position within the bottom groove 5. This movement is aided by that one of the two springs 17 which has been under increased tension. In a modification of the above embodiment, the helical springs 17 are replaced by flat leaf springs 18, Fig. 4 (not shown). In a further embodiment, Fig. 7 (not shown), a mandrel that extends the entire length of a core has a helical spring at each end that extends within a diametrical bore to hold the rollers in place. In a further embodiment, Fig. 5 (not shown), its chuck is in the form of a spider wheel with triangular heads at the peripheral ends of each spider arm. The toothed rollers are held in place by short tension springs 20 mounted in borings 20<SP>1</SP> in each head. In a further embodiment, Fig. 13 (not shown), cylindrical core chucks fit over the ends of a small diameter core. In a further embodiment, Fig. 15 (not shown), which is generally similar to Fig. 3, the peripheral recess 14 has its bottom formed by a platform 27<SP>11</SP> urged outwardly by springs 27<SP>1</SP>.

Filed: 1963-10-21
Abstract: 990,613. Road vehicle spring suspensions. DAIMLER-BENZ A.G. Oct. 21, 1963 [Oct. 24, 1962], No. 41533/63. Heading B7D. In an independent suspension for the front wheels of a motor vehicle, the lower of two triangular links 15, 16 supporting a wheel carrier 10 consists of one arm 23 of a transverse torsion bar stabilizer and a strut member 22 connected to the vehicle frame 17 by an elastic pivot 36 disposed forwardly of the wheel axis. Due to the pivot 36 being in front of the wheel axis so that the moment arm 39 about the pivot 36 of the lateral force Sa on the outside wheel when turning is greater than the moment arm 40 of the force Si on the inside wheel, and due to the stabilizer arm 23 being connected to the strut 22 and to the frame 17 by elastic sleeves 31, 32 providing greater resilience rearwardly of the vehicle than forwardly, the arm 22 and the lower end of the carrier 10 of the outer wheel deflect rearwardly when turning to decrease the castor angle of the outer wheel and reduce the steering effort required. Shims 29 between the pivot 36 and the frame 17 are removable for camber adjustment. The upper link 15 may consist of a construction similar to that of the lower link 16 but in reverse, or (as shown) comprises struts 41, 42 pivotally connected to the frame 17 by elastic sleeves mounted on a common pivot bolt 43. Stops 45, 46 on the strut 41 co-operate with a pin 47 on the carrier 10 to limit steering deflection. A track rod 48 connected to a lever arm 49 on the carrier 10 extends parallel with the strut 22 of the lower link 16. A coil spring 18 and a shock absorber are connected to the upper link 15.

Title: Circuit arrangement for supplying power to a load from a plurality of ac power sources
IPC: H02J9/06
Filed: 1972-09-07
Abstract: 1399756 Systems comprising two or more A.C. sources TELEFONAKTIEBOLAGET L M ERICSSON 7 Sept 1972 [7 Sept 1971] 41663/72 Heading H2H A system for supplying power to a load 10 from either or both in parallel of two A.C. sources 11, 12 comprises two back-to-back pairs of controllable rectifiers 19, 20 and 21, 22, the rectifiers being rendered conductive in a manner so as to supply the load with alternating current from whichever of the two sources has the higher voltage. The rectifiers may be thyristors or thyratrons or equivalent devices and the A.C. source 12 may be an inverter. When the load 10 is resistive the thyristors 19, 22 are rendered conductive during the whole of the relevant half cycles of the sources 11, 12, but if the load 10 is inductive they are rendered conductive only during the portions of the half cycles when the voltage applied to the load has the same polarity as the current flowing through the load. When the terminals X11, X12 are positive and Y11, Y12 negative thyristors 19, 21 are made conductive by the application of, gating pulses thereto. If the potentials at terminals X11, X12 are equal both sources 11, 12 will supply the load 10 in parallel. If the potential of X11 is higher than that of X12, the load 10 will be supplied by the source 11 only. If the potential of X12 is above X11 then the source 12 supplies the load. In the next half cycle when Y11, Y12 are positive the thyristors 20, 22 are rendered conductive and the load 10 receives power of opposite polarity. Voltage peaks in the reverse direction across the thyristors are avoided by means of resistors R1 and capacitors C1 in parallel therewith. Voltage stabilizers may be incorporated into the system arranged to stabilize either the supply voltages or the load voltages. The gating signals for the thyristors may be derived from the sources 11, 12 by way of circuits including transformers and transistors or alternatively may be derived from the load voltage or the current flowing in the load. Circuits are described for producing gating pulses according to whether the load is resistive or inductive.
