Abstract: 700,623. Moistureproofed regenerated cellulose film. BRITISH CELLOPHANE, Ltd. Nov. 27, 1951 [Nov. 29, 1950], No. 29272/50. Class 140 Regenerated cellulose film coated with a moistureproof coating on one side is produced by bringing a pair of dry regenerated cellulose films into intimate contact to form plies of a single web, coating this web on both sides with a moistureproof coating and separating the two plies of the coated web. The films may be produced on the same casting machine as described in Specification 423,365, [Group IV], and may be of the same width. During coating by dipping or spraying the films may be under longitudinal tension, e.g. 0.1-5 lbs. per inch width for film 0.0009 inch thick ; the coating may be 0.00005 inch thick. The liquid coating may be an aqueous dispersion of known co-polymers, such as vinylidene chloride/acrylonitrile, an organic solvent solution of nitrocellulose and high melting point paraffin wax, an organic solvent solution of a vinylidene chloride co-polymer, or a molten mixture of ethyl cellulose, non-heat convertible resin, plasticizer and wax. If the films prior to being brought into contact are impregnated with an aqueous dispersion of a partially condensed urea-formaldehyde resin the moistureproof coating may contain an acidic substance, e.g. citric acid or sulphur dioxide, which acts as a catalyst for the further condensation of the resin. Specification 700,619 is referred to.

[Class 40 (iv)] In a system having facilities for collecting particulars of a call and automatically recording them, in the event of the failure of the recording apparatus the particulars may be indicated temporarily for manual recording. Particulars of the call are stored in junction relay sets JRS as described in Specification 603,789 which are accessible over the banks of the hunting switch H, The apparatus is brought into use either by the printer alarm contact A or by the manually operated key KM. When a call is to be recorded earth over the start lead from the junction relay set operates ST and H hunts until K operates and locks over the T-wire. Relay KR operates and lights calling lamp LPC. The operator throws key KS and switch M steps slowly through interaction with PA and PB. The distributer switch in the junction relay set is stepped in synchronism with M over wire PU, causing relays W ... Z to operate in successive combinations to light lamps LP0 ... 9 to display successive digits giving details of the call. Lamps LPON, LPCN, LPD, connected to appropriate terminals of bank M4 indicate whether the calling number, the called number or the duration of the call is being displayed. Relay V operates over appropriate strappings to bank M2 .to close the circuits of lamps LP0 ... 9, and also to complete the pulsing circuit for the distributer in the junction relay circuit. The latter releases when the distributer reaches its home position, thereby releasing K and KR. To test the lamps key KT is thrown operating ST and sending H to its last position where the W ... Z relays are connected by appropriate strappings to banks M3, M5 to cause all the lamps to be lit in turn. Lamp LPS lights intermittently to indicate the stepping speed of M. When M reaches its last position K is shunted down by a connection to M5. Instead of lighting display lamps the earthing of the appropriate leads may be used to initiate a verbal announcement.

Title: Improvements in or relating to the manufacture of sulphuric acid
IPC: C01B17/84
Filed: 1951-12-19
Abstract: In the manufacture of sulphuric acid using nitric oxide present in gases obtained from the combustion with air of hydrogen sulphide or other starting materials containing sulphur to gases containing sulphur dioxide, the starting materials are burnt at temperatures above 100 DEG C using a limited excess of air, i.e. up to 100 per cent excess of the theoretical amount required for complete combustion of all combustible constituents of the starting material, and the nitric oxide thereby formed is protected from decomposition by immediate subsequent cooling of the combustion gas e.g. to 400 DEG C and the combustion gas containing nitric oxide is passed to a lead chamber or tower system to form sulphuric acid.  The cooling may be by passage through a waste heat boiler.  The use of the gases containing nitric oxide avoids or limits the addition of nitric oxide or nitric acid otherwise necessary to make up losses in the nitrosyl content of the circulating acid.  Specification 736,146 is referred to.

Filed: 1938-10-15
Abstract: 520,205. Inter-control of cage and well doors of lifts. HELLER, E. Oct. 15, 1938, No. 29938. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 17, 1939.] [Class 78 (iii)] The closing of the well door of an empty lift automatically closes the cage door, if open, but the latter can be both opened and closed by hand by the out-going passenger or by a passenger remaining in the cage. The automatic closing-mechanism, which contacts with the cage door but is not positively connected thereto, is controlled by two detents, one of which is released as the floor rises on the last passenger stepping out of the cage and the other when the well door is closed. Fig. 3 shows the arrangement in plan with the hinged cage door 9 and well door 16 both open. In this position the cage door can be moved freely in either direction up to the limit set by the pivoted arm 4 which carries a ratchet sector 10 engaged by two pawls 11, 12. The stepping of the last passenger from the cage allows the floor to rise and move pawl 12 vertically out of register with the sector 10. Closing of the well gate 16 causes the contact 17 to push the rod 13 axially and swing the pawl 11 free from the sector. When both pawls are disengaged, door-closing mechanism 3, 6, 7 of known type actuates the arm 4 to close the door 9. The latter, when pushed open by a passenger, drives the arm 4 in front of it, but the pawls prevent the return of the arm. A modification of the apparatus is described to deal with cages having double swing doors.
