Title: Improvements in or relating to telephone systems
IPC: H04Q5/02
Filed: 1934-05-30
Abstract: 434,446. Automatic exchange systems. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and CROWE, D. C., Ericsson Telephone Works, Beeston, Nottingham. May 30, 1934, No. 16130. [Class 40 (iv)] In a party line system, sub-stations are selected by applying different potentials to the lines, normally non- conducting devices, e.g. gas discharge tubes, being used to discriminate between the potentials applied. In addition, the polarity of the potentials may be varied to effect further selection by the use of polarized devices. In the 8-party line system shown, a relay R rectifier 22 and tube N are connected between one leg and ground at sub-stations 1-4 and between the other leg and ground at sub-stations 5 to 8 and selection is effected by applying + or - 100 volts to either leg and + or - 50 volts to the other. The selection of the line to which high voltage is applied restricts selection to sub-stations 1 to 4 or 5 to 8, the poling of the rectifiers 22 further restricts selection to a pair of substations, while the operation the two R relays to charge condensers 24 to + or - 50 volts which, on the relapse of the relays discharge over one or other of two bells 21, makes the final selection, depending on the polarity of rectifiers 23. Polarized relays and bells may be used instead of inserting rectifiers. The 100 volt supply is suitably interrupted or has superposed A.C. to provide intermittent ringing. As described, the potentials are applied over an auxiliary switch W set by an extra digit. When the final selector is set on outlet L1, L2, P relay A pulls up over the calling loop, the usual transmission bridge and ringing arrangements being omitted or, if the final selector also has access to ordinary lines, these arrangements are cut out if a level giving access to party lines is dialled. Relays B and C pull up and the additional digit is repeated to DM, the party line being opened until C falls back, whereupon the particular potentials determined by the setting of switch Ware connected to the line. Interrupters RI1 and RI2 of the usual ringing periods and rapid interrupters I1, I2 are connected in the + and - 100 volts leads. Two of the substation R relays are thus intermittently operated and one of the corresponding pair of bells 21 is pulsed by successive discharges of one of condensers 24. When the called party replies, either during a ringing or non- ringing period, slow-to-operate relay FA pulls up since the rectifier bridge 25, 26, 29, 30 provides an operating path whatever may be the polarity of the applied voltage. Relay F pulls up to complete the speaking path, the parties being fed over relays A, D. For outgoing calls, the loop extends over w1, w2 normal to the usual line circuit over X1, Y1.

Abstract: 471,951. Screw - cutting. B.S.A. TOOLS, Ltd., and OGILVIE, W. June 13, 1936, No. 16520. [Class 83 (iii)] A thread-cutting attachment for single or multispindle lathes is of the kind wherein a tool carried on a compound slide is operated by mechanism which is adapted to impart a longitudinal feed traverse in the operation of thread cutting, retraction of the tool transversely of the work, return to the commencement of the feed traverse, and engagement of the tool with the work, with automatic repetition of the cycle any desired number of times, and comprises a compound slide 3, 4, mounted on an adjustable base 2, carrying a tool 19, a housing 5 attached to the base having mounted therein a pair of lead screws 8, 9 in parallel relation and rotated in opposite directions by gears 10, 11, a lead nut 18, mounted on the upper slide and adapted for alternate engagement with each of the lead screws and means whereby lateral movement is imparted to the compound slide to bring the lead nut alternately into and out of engagement with the lead screws for imparting a longitudinal feed traverse and a return movement of the cutter. A trip rod 32, Fig. 5, secured to the longitudinal slide 4 carries adjustable 'collars 30, 31 and when the cutter reaches the end of a feed movement with the nut 18 in engagement with the lead screw 6 the collar 31 strikes a projection on a lever 29 which thus slides a collar 36, mounted on a shaft 24 carried by the housing 5, to the left and brings a lever 27 into engagement with a cam 25 which rotates with the return lead screw 7. The lever 27 is thereby rocked and this motion transmitted to a lever 23, Fig. 6, which withdraws the tool from the work and engages the nut 18 with the quick-return screw 7. A latch 46, Fig. 4, which holds the cross slide during cutting is automatically released prior to the retraction of this slide. When the tool is returned to its initial position the collar 30 acts similarly to slide the lever 28, integral with the lever 27, into the path of a cam 26 arranged adjacent to the cam 25, the nut is thereby thrown over to engage the lead screw 6 and the tool positioned for another working operation. The drive to the replaceable screws 6 and 7 is taken through a clutch 17, Fig. 2, which is operated by known cam and lever mechanism according to the sequence of operations on the work. The cutting tool 19, Fig. 6, is pinned at 63 to a worm wheel 62 adjusted by turning a spindle 61 facilitating resetting of the tool after it has been ground.

IPC: C07C67/00
Filed: 1965-04-20
Abstract: 1,133,762. Azines and isohydrazones and their use in the preparation of hydrazine. FISONS INDUSTRIAL CHEMICALS. 1 April, 1966 [20 April, 1965], No. 16666/65. Heading C2C. Azines and/or isohydrazones are obtained by reacting chlorine and gaseous ammonia to form chloramine in a first step and thereafter as a second step reacting the chloramine with aqueous ammonia and a carbonyl compound. They may be hydrolysed to form hydrazine, hydrazine hydrate or hydrazine salts. The preparation of the azines and/or isohydrazones may be effected in two separate shapes or as a sequential reaction in the same reactor when the chloramine may be formed in situ by the simultaneous introduction of chlorine and ammonia gases into the solution of the carbonyl compound and aqueous ammonia. The reaction is preferably effected in the presence of a strong base, e.g. an alkali metal hydroxide, at a pH of 12À8 to 13À5 when the reaction product is substantially the azine. The reaction may be effected at atmospheric or elevated pressures, continuously or batchwise, and the strong base is preferably fed to the reaction together with the chloramine. An agent such as gelatine or E.D.T.A. may be used in the second step of the process to sequester interfering ions. The azine may be converted to hydrazine salts by treatment with an acid, e.g. HC1 or H 2 SO 4 , or to hydrazine hydrate, e.g. by distillation, suitably under pressure. The isohydrazine or mixture of azine and isohydrazone may be converted to hydrazine salts with a strong acid or by treatment with cation exchange resins.
