Title: Process for the production of cyclododecadiene-mononitrosochlorides
Filed: 1960-05-31
Abstract: A mono - nitroso - chloride of cyclododecadiene is produced by the action of nitrosyl chloride on a solution of cyclododeca- 1, 5, 9-triene. The nitrosyl chloride may be reacted in the form of vapour, or as a solution in a solvent. In example 1, a solution of trans, trans, ciscyclododeca-1, 5, 9-triene in glacial acetic acid is mixed with a solution of nitrosyl chloride in glacial acetic acid. Crystals of 1- nitroso-2-chloro-cyclododeca-trans-cis 5, 9-diene are formed; these are filtered off, dried, and recrystallized from ethanol or hexane.  Example 2 describes the preparation of 1-nitroso-chlorocyclododeca - trans - trans - 5, 9 - diene from all trans - cyclododeca - 1, 5, 9-triene.  The Specification states that cyclododecanone oxime may be prepared from the cyclododecadiene - mono - nitroso - chlorides by hydrogenation of the two double bonds and removal of the chlorine atom. Specifications 848,951, 849,236 and 867,016 are referred to.

Title: Improvements in oxygen regulator
Inventor: JONES LEON
IPC: A62B9/02
Filed: 1957-06-21
Abstract: 823,114. Respiratory appliances. ROBERTSHAW-FULTON CONTROLS CO. June 21, 1957 [Aug. 28, 1956], No. 19659/57. Class 81 (2). [Also in Group XXIX] In a gas regulator in which a main valve is actuated by means of a pressure-sensitive auxiliary valve, an expansible chamber, located downstream of the main valve, serves to actuate the main valve, and gas, under pressure from the inlet, is admitted to this chamber to tend to expand it. In the embodiment shown the main valve 30 is held closed by bellows 36 to the interior of which gas is admitted, through duct 44, from inlet 12 and, although an equal pressure is admitted to chamber 20 through the main supply duct 18, the valve is held closed by the resilience of the bellows. The auxiliary valve 55, comprising a ball on a seating 54, is normally held closed by a lever 74 and spring 84, but, when gas is drawn through duct 68, thereby reducing the pressure below the diaphragm 64, the valve is opened and the pressure within the bellows 36 is vented so that pressure in chamber 20 opens valve 30 and gas passes through duct 22 to the outlet. When no further gas is withdrawn, pressure builds up in the auxiliary chamber 48 and causes closing of valve 55, after which pressure also builds up within the bellows 36, to close the main valve 30, the gas for this purpose being received through a restricted duct 44. In a modified form described with reference to Fig. 2 (not shown), the expansible chamber is formed by a flexible diaphragm closing a chamber in the body of the regulator and also serving as the movable member of the main valve.

Patent GB-199337-A (GB)
Abstract: 199,337. Western Electric Co., Ltd., (Western Electric Co., Inc.). Feb. 27, 1922. Drawings to Specification. Semi-automatic exchange systems; coin-freed systems.-In a system comprising a signal lamp controlled by a supervisory relay at a semi-automatic operator's position, the failure of a group selector to find an idle line in a selected group causes the flashing of the lamp at a definite frequency, whilst the busy condition of the wanted line causes the flashing of the lamp at a different frequency, the two flashings being effected by the intermittent energization of the supervisory relay in series with one or other of two interrupters, both of which are associated with the outgoing end of a trunk leading to the group selector. If the wanted line is free, the operation of a polarized relay bridged across the outgoing end of the trunk causes the continuous energization of the supervisory relay, and the consequent continuous lighting of the signal lamp indicates to the operator that she may initiate ringing. The system described is identical with that described in Specification 198,413 in which toll calls between automatic exchanges are established by toll operators over two-wire inter-exchange trunks.
