Title: Improvements in or relating to electric signalling systems
IPC: H04Q3/42
Filed: 1939-03-24
Abstract: 526,828. Party-line systems. STANDARD TELEPHONES & CABLES, Ltd., and BROWN, A. March 24, 1939, No. 9319. [Class 40 (iv)] Party-line substations of the type comprising a selector responsive to signals of the three-digit constant-total type from a control station as in train dispatching systems are enabled to intercommunicate by providing them with dials and providing the control station with apparatus which translates a two-digit dialled number into the corresponding constant total code. The dialled impulses are in the form of interruptions of the loop or of a simple circuit and do not affect the selectors and the constanttotal impulses are alternate positive and negative current impulses. One of the parties may be a telephone exchange operator with means for extending the line to the ordinary telephone network. Alternatively the apparatus at the control station in response to a characteristic digit may extend the line to an automatic exchange which is then controlled by the calling party in the usual way. Conversely, the line may be seized from an auto-. matic exchange apparatus at the control station converting digits dialled by the subscriber into the constant total code for calling the wanted party-line substation. Means may be provided for interconnecting two or more party-lines-with the aid of an additional switch at the control station. The detailed description only deals with setting up calls between parties on a single line. Circuit operations. Operation of the dialling key at a substation energizes the impulse relay IR at the control station and relays G, GA, DC pull up. Relay IR repeats the first dialled digit to the reverse-drive switch magnet SA. At the end of the digit DC falls and energizes DS which re-operates DC and directs the second digit to the switch magnet SB. At the end of this digit DC falls back again and on the subsequent restoration of the dialling key LC pulls-up and locks. Relays G, GA fall back and a pendulum relay PM which was energized by the operation of GA now gives impulses to SD and receives a kick over its right-hand winding at each impulse. Alternatively, the transmission of impulses may be initiated by the reception of the second digit, the dialling key remaining operated to hold the line busy. SD repeats the impulses to switch magnet SC. LC energizes BR to connect the line to the impulsing battery and IS gives impulses to reversing relay TR as the switch SC advances with two pauses the positions of which depend on the positions of switches SA, SB. The first pause is given by holding IS steadily operated, the second by keeping it de-energized. At the end of the last digit, IS remains steadily operated for about two seconds during which the selected substation is rung. IS is then finally released and an impulse is given to restore the called selector to normal. Subsequently, the switch SC releases LC.

Title: Improvements relating to electromagnetic clutches
IPC: F16D43/04
Filed: 1946-03-27
Abstract: 609,979. Clutches. LUCAS, Ltd., J., and LAIRD, J. A. March 27, 1946, No. 9460. [Class 80 (ii)] [Also in Group XXXVII] In an electromagnetic clutch, a rotary centrifugal switch is adapted to close the magnet circuit automatically to engage the clutch after a predetermined speed of rotation has been attained. The clutch comprises a driven disc c secured to a driven shaft d, and carrying friction faces h, situated between adjacent faces of a projection e on a driving member a and a flange f on an annular member g. The latter is rotatably secured to the member a by bolts i so as to be capable of slight axial movement relatively thereto. Energization of electromagnet windings m situated in a recess n in the driving member a causes the member c to be gripped between the faces of the parts e, f. Current is supplied to the windings through a brush o and a slip ring p via a rotary centrifugal switch mounted in a casing q. One embodiment of the switch, shown in Fig. 2, comprises a contact s, secured to a resilient metal strip t, which engages a contact r under the centrifugal action of a weight v when the engine. reaches a predetermined speed. In order that the clutch may be disengaged at a speed lower than that at which it becomes engaged, a switch x, y, z in parallel with the other switch is held closed by a permanent magnet 5 until the decrease in centrifugal force and the force of a spring 3 are sufficient to overcome the attraction of the magnet 5. In a switch modification, the metal strip z acts directly on the strip t and the contacts x and y are omitted.

Title: Improvements in or relating to Aerial Arrangements of the Radiating Aperture Type
IPC: H01Q25/04
Filed: 1967-02-28
Abstract: 1,179,768. Aerials. TELEFUNKEN PATENTVERWERTUNGS-G.m.b.H. 28 Feb., 1967 [9 March, 1966], No. 9552/67. Heading H4A. In an aerial arrangement comprising a multimode waveguide leading at one end to a radiating aperture, which may be in a radio horn, and fed at the other end by a plurality of monomode waveguides, the relative amplitudes of the various modes developed in the multimode waveguide, and hence the energy distribution pattern across the radiating aperture, are made to conform to predetermined values by suitably spacing apart the feeder waveguides, which are supplied at predetermined amplitudes, and either in phase or in anti-phase. In a first embodiment, two parallel rectangular waveguides 4, 5, Fig. 2, each of crosssectional dimensions a x b feed into one end of a third parallel waveguide 3, of cross-sectional dimensions a<SP>1</SP> Î b and length c. At the frequency of operation the waveguides 4, 5 can support only the H 10  mode, but the waveguide 3 can support higher modes in addition to the H 10  mode. If the waveguides 4, 5 are supplied in phase, at equal amplitudes, the H 10  and H 30  modes are developed in the waveguide 3. The desired relative magnitudes of the H 10  and H 30  modes are obtained by suitably choosing the spacing apart of the waveguides 4, 5 in the H-plane. It is also possible to develop the H 40  mode in the waveguide 3 and, by supplying the waveguides 4, 5 in anti-phase, the H 20  mode. In a second embodiment, three waveguides similar to the waveguides 4, 5, Fig. 2, feed a suitably dimensioned multimode waveguide in which the H 50  mode is thereby developed. In a third embodiment, two feeder waveguides 6, 7, Fig. 6, are spaced apart in the E- plane and excite a multimode waveguide 8. The waveguides 6, 7 allow only the H 10  mode to be transmitted, but in the waveguide 8 the H 10 ,H 11 ,E 11 , H 12  and E 12  modes can exist. In a fourth embodiment, a third feeder waveguide is provided between two feeder waveguides such as 6, 7, Fig. 6, so that higher modes can be developed in a suitably dimensioned multimode waveguide, and a fifth embodiment (Fig. 10) consists of a combination of the first and third embodiments (Figs. 2 and 6). The arrangements are stated to be particularly applicable to monopulse operation and by means of coupling devices sum and difference patterns may be developed with low side-lobe effects. Reference has been directed by the Comptroller to Specification 1,002,140.

Title: Improvements in or relating to processes for the hydrolysis of methyl acetate and the treatment of aqueous mixtures of methyl acetate, methyl alcohol and acetic acid so obtained
IPC: C07C51/09
Filed: 1951-04-26
Abstract: Methyl acetate is hydrolysed with water in the presence of a hydrolysation catalyst at a pressure above atmospheric and an elevated temperature below the boiling-point of the mixture at said pressure.  The catalyst may be a strong acid, e.g. sulphuric acid equivalent to 0.05-2, preferably about 1 per cent by weight of the reactants.  Temperature may be 48-140 DEG  C. and pressure up to 10 atm., e.g. 100 DEG  C. at 3 atm., or 115 DEG  C. at 6 atm.  The ratio of water to ester is preferably such that only 20-70 per cent is hydrolysed, viz. 0.3-2 : 1.  The hydrolysis mixture is preferably subjected to the reaction conditions for 10-45 minutes.  The mixture of acetic acid, methanol, methyl acetate and water obtained by said hydrolysis is distilled, the overhead of methanol and methyl acetate being in part returned as reflux, and in part scrubbed with water to give aqueous methanol and the ester.  The bottoms of aqueous acetic acid is extracted with methyl acetate which may contain 10-25 per cent of cyclohexane, the extract then being distilled to drive off solvent and water and recover anhydrous acid.  The methyl acetate for the extraction may be part of the feed to the hydrolysis or the product of the water scrubbing.
