Title: Removal of sulphur dioxide from gas streams - by scrubbing - with magnesium (bi) sulphite solns
Inventor: SHAH INDRAVADAN SHANTILAL
IPC: B01D47/10
Filed: 1971-10-27
Abstract: Gas stream is passed downwards through a vertical, annular venturi passage having a central conical flow diversion baffle and a first portion of the aqs. scrubbing soln. contg. MgSO3 and Mg(HSO3)2 is sprayed centrally downwards above the apex of the baffle and the second portion flows downwards on the inner surface of the upper converging section of the venturi passage. The gas stream is scrubbed in the annular throat section of the passage and SO2 is absorbed to form further Mg(HSO3)2 in soln., the overall scrubbing liquid to gas flow ratio being 5:1. The resulting scrubbing soln. is separated and divided into two portions. The first, comprising 1 - 30% of the total, is evaporated to remove water and ppte Mg sulphite-bisulphite crystals which are heated to produce an SO2-rich gas stream and MgO. The MgO and water is added to the second portion of the scrubbing soln. to convert Mg(HSO3)2 to MgSO3 and this second portion is then recycled. Scrubbing efficiency is improved using low liquid to gas flow rates.

Title: Sound and cine system for small camera - is fitted with camera motor activated by tape deck switch in standby position
Inventor: STRACK PETER
IPC: G03B31/04
Filed: 1973-10-26
Abstract: Sound/cine systems for the home movie equipment suffer from relay 'clicks' drop out and other faults on the tape, while correct synchronisation is difficult. to overcome this a socket is provided in the camera motor circuit, to break the circuit and connect it via a connecting cable to a switch on the tape recorder. The tape recorder is set in the standby mode and the remote camera motor switch is mechanically coupled to the clutch for the tape. This enables the tape and film to start together with minimal acceleration time. For replay, the two systems are merely synchronised at the start and remain synchronised for the length of the film and tape. The tape faults associated with conventional systems do not occur and so not have to be cut out.
