[Class 98 (i)] The shutter of a photographic camera is set and released and the sensitive material advanced by motor-operated devices, the motor of which is controlled by means producing electric current impulses. An electric motor 58 drives a shaft 77 through a clutch 57 and a toothed drive 75, 76. Mounted on the shaft 77 are worms 78, 59 for actuating the film feed roller and tensioning the shutter spindle respectively. The motor is kept permanently running but the clutch 57 is actuated by impulses. The clutch is under the control of an electromagnet 55, the armature 54 being itself a lever, or attached to a lever 54a, which acts on the clutch 57. A cam 31 actuates a contact 60 in the circuit of the electromagnet and is rotated by a friction wheel 61 running on a disc 32 driven through worm wheel gearing 33 from an electric motor 62. The wheel 61 is adjustable on the shaft 30 to give a variable rate of rotation thereof. When the clutch is effective, the motor 58 also drives a contact disc 63 in the circuit of a second electromagnet 56 and after the film has been advanced and the shutter set, the disc 63 closes the circuit and attracts the armature 54 to release the clutch 57. A spring 37 holds the clutch in engagement when the film is being wound and the shutter set. A feeler device interrupts the circuit of the motor when the film is completely unwound from the spool. When the camera is adapted for aerial photography, the rate of current impulses is adjusted to match the speed and height of the aircraft.

Title: Improvements in pressure gauge of the aneroid type for pressure measuring in gas or liquid
IPC: G01L7/00
Filed: 1942-03-13
Abstract: 557,518. Relay devices. CARPMAEL, A. (Svenska Aeroplan Aktiebolaget.). March 13, 1942, No. 3363. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 8, 1942.] [Class 118 (ii)] [Also in Group XIX] In a gauge of the aneroid type, wherein the pressure exercises a turning moment on a measuring shaft and the shaft is supported by a helical spring subject to torsion and exercising a turning moment counteracting that transmitted to the shaft by the pressure, two pressure sensitive membranes are employed connected directly to the measuring shaft by steel bands fixed to the shaft. Two aneroid boxes 3, 3<SP>1</SP> in a casing 1 are connected at their centres by a steel band 5 passing through an aperture in a measuring shaft 6. The shaft 6 floats and has one end connected to the casing by a tensional wire 8 the other end being connected to one end of a coaxial tension spring 7 the other end of which is mounted in the casing. When the pressure on the boxes increases, the shaft 6 turns. It is turned back to normal by applying an opposite torque by a servomotor device. The end of the spring 7 is rigid with a coaxial pulley 9 which may be rotated by a rope 11 from a pulley 10 in one with a ratchet wheel 12. A constantly running motor 13 drives through a crank and link 14, 15 a guided piston device 16 through which passes a rod 19 attached to the link 15. The part 16 is pressed by a spring 20 against a cross piece 21. Normally the part 16 is held by a stop 23 pressed below it by a spring 27. Normally, contacts 28, 29 are broken as shown, but when the pressure increases the shaft 6 is turned to cause them to contact. This energises solenoid 22 to retract the stop 23 whereupon the part 16 and panel 15 are reciprocated to feed the wheel 12 so that contacts 28, 29 are broken and the stop 23 restored, the wheel 12 being held by a panel 26.

Title: A process for improving the colour of aqueous solutions of saturated acid sulphuric acid esters or of saturated sulphonic acids or the salts thereof
Filed: 1947-02-05
Abstract: The colour of aqueous solutions of saturated acid sulphuric acid esters or of saturated sulphonic acids (which esters or acids are derived from hydrocarbons, e.g. alkenes or monohydric aliphatic alcohols), or the salts thereof, is improved by treatment with less than 1 per cent by weight of peroxides or salts of weak per-acids or mixtures of these substances. Peroxides instanced are hydrogen peroxide, partial combustion products of lower-boiling hydrocarbons (a peroxide-containing mixture), benzoyl and sodium peroxide.  Sodium perborate and per-carbonate are instanced as weak per-acid salts. Neutral or weakly acid conditions are preferred and the use of elevated temperatures accelerates the reaction.  In examples: (1) an aqueous solution of sodium salts of acid sulphuric acid esters, obtained from sulphuric acid and an alkene mixture with about 10 to 18 carbon atoms in the molecule, is treated with 0.1 per cent of sodium peroxide at 75 DEG  C., and in (2) an aqueous solution of sodium sulphonates, obtained via the sulphochlorination of a de-aromatised gas oil, and with a pH of 8.0 is treated with 0.05 per cent of a 30 per cent solution of hydrogen peroxide at room temperature or boiling point.
