Title: Improvements in or relating to multiple switches for establishing a number of simultaneous connections between two groups of conductor systems
IPC: H01P1/12
Filed: 1950-07-05
Abstract: 673,295. Regulating switches; air-break switches. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 5, 1950. [July 7, 1949] No. 16783/50. Class 38 (v). [Also in Group XL (c)] Any one of a number of circuits 13, e.g., radio transmitters or receivers, may be connected to any one of a number of circuits 15, e.g. aerials, by a switch having a switch arm 4 for each circuit 13 rotatable about a common axis 1, each arm 4 carrying contacts 9 connected to a circuit 13 and co-operating with a single arcuate bank of contacts 11 connected to the aerials 15, the contacts 9 being retractable relatively to the arms 4, so that they do not interfere with the other arms on movement of one arm. The contacts 9 are carried by supports 7 rectilinearly movable in tubular guides 6 carried by the arms 4, only one of which is shown. Each arm has an operating mechanism 18 driving a pinion 22 round a fixed rack 21 so as to rotate the arm. The mechanism 18 comprises an electric motor 30 driving two outlets 33, 37 through a differential gear 32, each outlet having a ratchet wheel 39, 40 alternatively engageable by an electromagnetically-operated pawl 41 to lock that outlet. Outlet 33 drives a crank and connecting rod 34, 35 to reciprocate the contacts 9, and outlet 37 drives the pinion 22 over a reversing mechanism 38, a disc P having contact segments P1, P2 also being driven by outlet 37. Each switch arm is controlled by a separate manual switch A, Fig. 4, having, contacts 47 which may be selected by an arm 46, the contacts 47 being connected to contacts 42 co-operating with the contact segments PI, P2, so that on movement of arm 46, a relay R2 is energized over a contact 47, a contact 42, and a segment P1 or P2 to close contacts R21 and open R22, the former energizing motor 30. Also since a switch S2, operable by a pawl 45 in outlet 33, is closed, the electromagnet M1 of pawl 41 is energized to lock outlet 37 and free outlet 33. The contacts 9 are then retracted and at the same time switch S2 is opened and a switch S1 closed. The electromagnet M1 is therefore de-energized and the pawl 41 changes over to lock outlet 33 and free outlet 37, so that the arm 4 is rotated until the segments P1, P2 disengage the contact 42 which is connected to the selected contact 47, the direction of rotation depending on which segment P1, or P2 is initially in contact with said contact 42, i.e., whether relay R2 alone, or R1 and R2, are energized ; if the latter, an electromagnet M2 is energized to operate the reversing mechanism 38. Relays R1 and/or R2 are now de-energized so that contacts R22 close and R21 open, thereby energizing magnet M1 to free outlet 37 so that the contacts 9 are moved into engagement with the selected contacts 11. At the end of this movement, switch Sl is opened (to de-energize motor 30 and electromagnet M1) and switch S2 is closed. Contacts O operated by the other switch arms are provided to prevent simultaneous connection of two arms to the same aerial.

Filed: 1962-05-07
Abstract: 993,165. Purification of diphenylol alkanes. RUTGERSWERKE UND TEERVERWERTUNG A.G. May 7, 1962 [July 12, 1961], No. 17409/62. Heading BIB. A diphenylol alkane, obtained by the condensation of phenol with a carbonyl compound in the presence of hydrochloric acid, is freed from hydrochloric acid and water by azeotropic distillation in the presence of an organic liquid which is insoluble in hydrochloric acid and has a lower boiling point than phenol, e.g. benzene, n-heptane, toluene, monochlorobenzene or xylene. The reaction mixture is fed into column 1 via line 2 and is distilled in presence of the organic liquid, e.g. toluene. An azeotropic mixture of HCI, water and toluene distils over and condenses in condenser 3. The condensate separates into two layers in decanter 4, the toluene layer being returned to column 1 via line 5, and the aqueous HCl layer being removed via line 7. Part of this aqueous HCl layer is bled off via line 6 and returned to column 1 as a reflux. The bottoms product from column 1, containing the diphenylol alkane, phenol and toluene, is pumped into column 9 via line 8, and is distilled under vacuum to remove the toluene. Part of the toluene thus recovered is returned to column 9 via line 11, and the rest of it is passed into column 1 via lines 10 and 5. The bottoms product from column 9, comprising a mixture of the diphenylol alkane and phenol free from HCl, water and toluene, is withdrawn via line 13. Two examples are given illustrating the azeotropic distillation of the reaction mixture obtained in the preparation of 2,2-bis(4-oxyphenyl)propane, using toluene and benzene respectively as azeotrope formers.
