Abstract: Emulsifying agents comprise acylated polyglycol ethers prepared by reacting a fatty acid having at least 12 but not more than 22 carbon atoms with a quantity of ethylene oxide such that at least 2 mols but less than 4 mols of ethylene oxide are reacted with each mol of fatty acid (see Group IV).  Examples describe products obtained from ethylene oxide and pure or commercial stearic acid, oleic acid and coconut oil fatty acid.  Other acids mentioned are lauric acid, myristic acid, palmitic acid, hardened train oil fatty acid, arachic acid and ricinoleic or hardened ricinoleic acid.  The Specification as open to inspection under Sect. 91 includes the use of any fatty acid having at least 12 carbon atoms.  This subject-matter does not appear in the Specification as accepted.ALSO:Acylated polyglycol ethers are prepared by reacting a fatty acid containing at least 12 carbon atoms but not more than 22 carbon atoms with a quantity of ethylene oxide, at a raised temperature under superatmospheric pressure in the presence of a substance having an alkaline reaction, such that for every mol. of the fatty acid at least 2 mols. but less than 4 mols. of ethylene oxide enter into reaction with the fatty acid.  Reaction at 120-180 DEG  C. and 4-10 atmospheres is satisfactory.  The substances of alkaline reaction may be alkali hydroxides or alkali salts of carboxylic acids.  The products are water-soluble or -dispersible; they may be used as textile assistants, for example, as agents for preventing agglomeration of staple fibres of regenerated cellulose, for imparting a scroopy feel and for improving the capacity of the fibres for being spun and as emulsifying agents (see Group III).  Examples described (1) products obtained by reacting ethylene oxide as above with pure and commercial stearic acid, oleic acid and coconut oil fatty acid in the presence of sodium acetate, sodium butyrate or sodium stearate and (2) the treatment of artificial wool composed of regenerated cellulose with an aqueous solution of the stearic acid-ethylene oxide product of (1) to give the wool a scroopy feel.  Other fatty acid starting materials specified are lauric acid, myristic acid, palmitic acid, hardened train oil fatty acid, arachic acid, ricinoleic and hardened ricinoleic acid.  The Specification as open to inspection under Sect. 91 includes the use of any fatty acid having at least 12 carbon atoms and states that a strong acid or acid salt may replace the substance of alkaline reaction.

Title: A circuit arrangement in a carrier frequency transmission system
IPC: H04B17/40
Filed: 1964-05-27
Abstract: 1,023,568. Supervising unattended repeaters. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 27, 1964 [May 27, 1963], No. 22002/64. Heading H4R. A repeater station for a carrier current transmission system comprises, Fig. 5, repeater amplifiers associated with respective coaxial cables for each direction of transmission the amplifiers being powered by current supplied over the centre conductor of the cables, the power loop being completed over the go and return paths of a section of the cable, e.g. half the distance between attended monitor stations, with the power source located at an attended monitor station. Two line pairs 13 and 14 are associated one with each direction of transmission as fault indicating lines which may be bridged on the occurrence of a fault in the repeater, the resistance of the loop of line as measured from the monitoring station indicating the location of the fault. The bridging of the line 13 is arranged to occur when both contacts 25 and contacts 37 are closed, and contacts 25 close when the pilot signal level transmitted through the associated amplifier falls below a predetermined level while contacts 37 close if both the power supply current in the coaxial line and the voltage between the go and return lines falls to zero. For the other direction of transmission, i.e. on line 14, the contact 39 again closes for a drop in pilot signal level but contacts 42 close only when the current falls to zero while the voltage between the lines remains at a predetermined level. Fig. 2 shows the effect on the shorting devices across the monitoring lines of a fault occurring in repeater 3, the upper line remaining open at repeaters 1 and 2 because both pilot signal and line voltage are present, while the line is bridged at repeaters 3, 4 and 5, because the pilot signal, line current, and line voltage are all zero. In the return direction, i.e. B - # A the lower line is bridged at repeaters 1, 2 and 3, because line current, and pilot signal are zero but the line voltage is present between the two coaxial cables, at repeaters 4 and 5 the line current and pilot voltage are zero and the line voltage is also zero and therefore the line is not bridged at these repeaters. The position of the faulty repeater can thus be ascertained from either end of the line. It is suggested that operation of the relays might switch in an alternative supply to the repeaters.

Abstract: 221,532. Smith, T. F. May 7, 1923. Two - stoke - cycle engines.-A plate 1 is interposed between the cylinder 2 and the crank case 3 so that a charge, drawn into the cylinder by the piston 5, is compressed between the piston and the plate before being transferred to the outer portion of the cylinder to be further compressed by the piston prior to the ignition. The charge enters the cylinder by a port 9, and after the first compression it passes by way of ports 11, 10 and a passage 12 to the combustion chamber, the exhaust taking place through a port 14. Fig. 1 shows a single-cylinder air-cooled engine in which the piston-rod 4 is connected to the crank-pin 7 by a short rod 6, the piston-rod having a slipper 4<a> sliding in a guide 4b. The piston-rod works in a gland 8 held in place by two studs and the connection with the piston is effected by a pin of driving fit. An engine can be built up of a number of such cylinders all independent of one another. An engine with opposed cylinders and with piston-rods connected to a common crankpin is also described. Reference has been directed by the Comptroller to Specifications 10563/11, 19761/14, 100,873, 144,852, 145,217, and 167,180.

Abstract: 313,361. Hubbard, H. E. Aug. 1, 1928. Addressing and like machines; printing-surfaces.-A printing-plate for use in addressing and like machines has each longitudinal edge bent over to form margins 9 of double thickness, the layers of the bent portions being firmly compressed and flattened and lying substantially in the plane of the main part of the plate at the front surface and beyond the plane of the main part at the rear. A recess is thus formed at the back of the plate deep enough to accommodate the embossed characters on an adjacent plate when a number of plates are stacked in a drawer 5, and space is economized in storing them; also, shoulders 10 are formed which protect the extreme edges of the plate. At each side edge, notches 12, 13 are formed either pair of which may engage a guiding-rib 6 in the drawer so that the plates may be stacked either way up; also, the notches are slightly larger than the ribs to allow the plates to incline slightly so that the characters may be read. Further, to facilitate placing a blank right side up in a stamping-machine, or to facilitate arranging the plates correctly in the drawer, one or both notches 12 may have an inclined side 15.

Abstract: 770,015. Haymaking machines. BAMFORDS, Ltd. July 14, 1955 [July 31, 1954], No. 22397/54 Class 6(3). Relates to haymaking machines of the type having rake-wheels arranged in oblique echelon formation and mounted in groups 19, 19a each of which turns one of a number of adjacent swaths. According to the invention, one or more of the groups are mounted for bodily movement along a frame member 11 which is transverse to the line of travel of the machine so that the transverse distance between two groups may be varied. As shown in Fig. 1, the main frame is roughly D-shaped and comprises box-section members 11, 12 mounted on wheels 13, 14, 15 of which the foremost, 13, is steerable and the remainder are swivel-wheels lockable in at least two positions. The member 12 carries bearings 17 for the cranked axles 18 of rakewheels 19 and a similar set of bearings is provided at the front of the member 11. A channel-section member 21 embraces three sides of the member 11 and carries, on its underside, bearings 17a for the cranked axles 18a of the rake-wheels 19a. The channel-member 21 is slidable longitudinally of the frame-member 11 and is lockable by pivoted bolts 25 which engage fixed lugs 28. For side delivery, the sliding member is in its rearmost position and the cranked axles 18 are removed from the member 12 and inserted in the fixed bearings on the member 11, so that the rake wheels 19 lie in a single line. For swath-turning, the wheels from two groups of which the second, 19a, is slidable bodily upon the member 11 thereby varying both the longitudinal and transverse distances between the groups. In a modification, Fig. 5, the member 21 is slidable upon two parallel tubular frame members 11a, 11b so as to occupy various transverse positions and also a position wherein the group 19a is aligned with the rake-wheel group 19, the axles 18a being oppositely cranked from the axles 19b to reduce the required length of the frame. The rakewheels may be spring-supported and may be positively driven. Specifications 712,992 and 767,331 are referred to.

Abstract: 727,320. Protective cut-out arrangements. METROPOLITAN VICKERS ELECTRICAL CO., Ltd. Sept. 23, 1952 [Sept. 26, 1951], No. 22516/51. Class 38 (5). In a remote control arrangement in which the control of a circuit-breaker or contactor (not shown) is effected by a relay having a winding 1 connected in series with a low voltage A.C. supply 2, a pilot line 3, a remote switch 4, a half-wave rectifier 5 and an earth return, a local circuit is arranged to be completed when the relay and circuit-breaker close to cause a backing current to flow in the winding or in a further winding of the relay. This reduces the holding power of the relay to make the system more sensitive to changes in resistance in the pilot circuit without making it more sensitive to changes in the supply voltage. In Fig. 1, the local circuit comprises a resistor 6 in series with auxiliary contacts C of the relay or circuit-breaker and a half-wave rectifier 7 of opposite polarity to rectifier 5. When the switch 4 is closed " forward " half-wave rectified current flows through the relay winding 1 to close the relay. The resulting closure of the contacts C causes half-wave rectified backing current of opposite polarity to flow through the relay coil to produce an opposing effect so weakening the holding power of the relay. In Fig. 2 (not shown) the backing current may flow through a separate additional winding on the relay, the additional winding being connected in series with the local circuit. In either arrangement the relay may be provided with a further shortcircuited winding as described in Specification 700,472. In a further arrangement, Fig. 3, the relay has parallel-connected relay coils 1a, 1b, associated with rectifiers 8a, 8b, 9a, 9b. When the switch 4 is closed current flows through the .rectifier 9a, coil la and rectifier 5 to close the relay. Then on the closure of contacts C the backing current flows through the rectifier 7, the coil 1 b and the rectifier 9b to reduce the holding power of the relay.
