Title: Improvements in or relating to duplex and like telegraphic systems
IPC: H04L5/14
Filed: 1920-04-24
Abstract: 166,970. Sullivan, H. W. April 24,1920. Artificial lines.-In order to represent more closely the signalling line, more particularly as regards the absorption properties of the insulation, a length of cable core (conductor and insulating covering) having the ratio of its electrical constants substantially the same as that of the signalling line, is used at the home end of the artificial line in substitution for one or more of the ordinary artificial boxes. The cable core may be formed into two coaxial coils 2, 3 of opposite sense and immersed in water in a tank 4, or may be in the form of a bight which may be laid under water. In the latter form, the signalling line 10, Fig. 2, and the artificial-line cores 8, 9 may be laid up side by side in a common covering, which may include armouring at the shore end. Cores 8, 9 are subsequently connected at 11 and the joint insulated. In either form, the cable core is connected at the home end of the artificial line in series with the remainder 6. For long distance work, when the cable cores of the artificial and signalling lines are identical, the length used in the artificial line may be 3 to 6 per cent of the length of the real line, the remainder being represented by the usual artificialline condensers, but by suitably selecting the actual values of the constants this proportion can be varied.

Title: Control equipment for induction motors
IPC: H02P23/00
Filed: 1959-04-03
Abstract: 922,843. Control of A.C. motors. F. DE'DIFNICO. April 3, 1959 [April 3, 1958], No. 11442/59. Drawings to Specification. Class 38 (3). [Also in Group XXXV] Relates to the control of reversible induction motors whose rotor resistance is such that the torque increases continuously over a range from zero slip to 200% slip. Means are provided to afford an alternating stator flux which is gradually changeable to a rotating flux in either direction. A single-phase motor has two poles displaced through 90 degrees, and each pole-winding is in series with a phase-displacing impedance which may be gradually changed from being wholly capacitive to wholly inductive. A two-phase motor has one of its polewindings associated with phase-shift regulators, which may be auto-transformers, and a three-phase motor has such regulators associated with two of its pole-windings. In another arrangement, a pole is angularly displaceable around the rotor axis, the rotor being divided into two portions which are mechanically coupled and each associated with a single pole. A three-phase motor has its rotor divided into three parts, each associated with a pole, two of the poles being angularly displaceable. Each pole may have an auxiliary winding which is short-circuited, or associated with series impedance for speed regulation. In a further embodiment, the motor has a regulator with three pairs of windings, the windings of each pair being series-connected and one situated on a stator and the other on a rotor. In one position of the rotor the regulator windings are aligned to provide maximum flux linkage and maximum inductance, the motor then being stationary. Adjustment of the rotor of the regulator in either direction causes the motor to run in one direction or the other. Another regulator comprises two reactors connected to the motor windings through sliding contacts. Alternatively, the reactors may be saturable.

Title: Improvements in and relating to processes for obtaining sulphuric acid esters from oils, fats, their fatty acids or mixtures thereof
IPC: C11C3/00
Filed: 1936-04-23
Abstract: The reaction mixtures containing sulphuric esters obtained by treating with sulphonating agents, oils, fats or fatty acids which contain a hydroxy group or double bond, are treated, in the presence of an appropriate amount of water with a sufficient amount of an alkaline earth or heavy metal compound to convert the unsulphonated products into insoluble salts (soaps) while the sulphonated products remain in solution.  The sulphonated mixture may be neutralized before being treated with the alkaline earth or heavy metal compound, examples of which are oxides, hydroxides or salts of the alkaline earths or heavy metals such as slaked lime, calcium chloride, zinc carbonate, chromium hydroxide, ferric chloride, lead carbonate, copper sulphate and mercuricchloride. In examples: (1) turkey red oil is gently heated with slaked lime and the soluble sulphuric esters separated by filtration, if necessary after the addition of water; (2) a sulphonated oil containing more sulphuric acid combined in ester-like form than that used in example 1 is treated with aqueous calcium chloride and the insoluble soap separated; (3) a sulphonated olein is washed with Glauber's salt and treated with zinc carbonate and worked up as in the previous examples; (4) a highly sulphated ester product is neutralized and then treated with lead acetate. Specifications 2896/96, 24868/97, [both in Class 91], 293,480, and 293,717, [both in Class 2 (iii)], are referred to.ALSO:The reaction mixtures containing sulphuric esters obtained by treating oils, fats or fatty acids which contain a double bond or hydroxy group with sulphonating agents, are treated in the presence of an appropriate amount of water with a sufficient amount of a heavy metal compound to convert the unsulphonated products into insoluble soaps, while the sulphonated products remain in solution.

Title: Improvements relating to wobbler mechanism
IPC: F16H23/06
Filed: 1939-04-19
Abstract: 527,740. Wobbler mechanism. NAAMLOOZE VENNOOTSCHAP HULSEMO. April 19, 1939, No. 11819. Convention date, April 20, 1938. [Class 80 (iii)] In wobbler mechanism in which the free end of each of the piston-rods is apertured to present two substantially flat opposed surfaces perpendicular to the piston axis between which surfaces a part of the wobbler is received, the height of the apertured piston-rod end is smaller than the diameter of the piston, and the cap closing the aperture at the free end of the piston-rod is secured to the piston-rod by axially extending bolts. A tubular piston-rod 2, Fig. 1, is secured to the piston 1 by T-bolts 3 and an insulating plate 21 may be interposed. The aperture in the rod is formed by the rod itself, two projecting parts 2b thereof and an end cap 4 which is secured to the rods by longitudinally extending bolts 5. The cap, forged from light metal, serves also as a crosshead and for this purpose is provided with projections 6 which slide along U-shaped strips 7 which are drawn against an extension 9 of the cylinder wall by bolts 8. The aperture is made as shallow as possible and has two flat surfaces 10, 11 covered by plates 12, 13 on which the shoes 14, 15 slide. The plate 12 has projecting parts 20 which prevent oil from splashing against the end of the piston. In a modification, the piston body is formed integrally with the rod 2 as one light forging, the rod-being of approximately dumbbell shape in cross-section. In a further modification, the rod is integral with the piston and is screwthreaded into the apertured part. In a still further modification, the apertured rod end is itself extended to form the oil deflectors. In Fig. 9, the guiding of the pistons is effected on both sides thereof. On one side is a guiding piece 24 secured by bolts 25 to the cylinder extension 26. and co-operates with flat surfaces 28, 29 of the apertured rod end, and on the other side are plates 30 secured by bolts 31 to the lower side of the extension 26, flat faces 32 at the edges of each plate guiding the surfaces 33 of two adjacent pistons. When the piston-rod is removably attached to the piston body, the connection between rod and piston is preferably made weaker than that between the cap and the remainder of the rod. Specifications 350,308, 475,262, and 484,366 are referred to.

Title: Improvements in or relating to indexing means for devices arranged to be rotatable step-wise
IPC: B23Q16/10
Filed: 1942-08-21
Abstract: 565,018. Lathe turrets; indexing. BAIGENT, G. M. Aug. 21, 1942, No. 11827. [Class 83 (iii)] In rotating and locking means for indexable members such as lathe turrets, the turret 13 is removably secured to a shaft 12 axially slidable and rotatable within a sleeve 10 splined within the turret casing 11. Dogs 15, 16 on the turret and sleeve respectively have the same pitch as the tool stations in the turret and are normally pressed into engagement by a spring 25 located between a pin 24 on the shaft and a collar 17 in the sleeve. For indexing the turret, the sleeve is moved rearwardly by a fork &c. engaging a bolt 18 thereon so as to disengage the dogs 15, 16, continued motion of the sleeve causing a toothed or friction clutch 20 secured thereto to mesh with a similar collar 21 loose on the shaft and move the collar axially to cause rotation of the shaft through a pin and helical slot connection 22. A spring-pressed pin 34 in the sleeve coacts with indexing recesses 37 in a plate 31 removably secured to the shaft in order to prevent overrunning of the turret. In an alternative construction, the turret may be mounted on the sleeve 10 and axial motion imparted to the shaft 12. The turret and plate 31 may be replaced by others suited to a different pitch of tools and the motion of the pin along the slot 22 may be limited in some cases by an adjustable stop to suit the angular motion required. A pin or balls 29 are located in a radial hole in the sleeve and coact with an annular recess 28 in the shaft so as to project beyond the periphery of the sleeve when the dogs 15, 16 are not in engagement and thus prevent forward feed of the turret, if this has not been properly indexed, by fouling a shoulder 30 on the casing 11. The indexing-mechanism may be used in connection with the safety device described in Specification 565,021, which co-operates with a recess 38 in the turret and may also be used with the dashpot control described in Specification 565,020, actuated by stops 33 on the plate 31. Specification 565,019 is also referred to. Milling.-The indexing-device may be used for milling gear-wheels or toothed quadrants having odd pitches, in which case the sleeve 10 and shaft 12 would each be provided with removable members having the same number of coacting dogs as the teeth in the wheel to be cut.
