Title: Improvements relating to moving coil loudspeakers
IPC: H04R9/02
Filed: 1949-08-17
Abstract: 670,667. Loud-speakers. WILLSON, H. C. Oct. 9, 1950 [Aug. 17, 1949], No. 21434/49. Class 40 (iv). [Also in Group XL (b)] In a moving-coil loud-speaker, the stray magnetic field which may have a deleterious effect on the performance of adjacent equipment, e.g. in a television receiver, is neutralized by reversing the direction of the residual magnetism in certain of the loud-speaker components. The current necessary in a predetermined coil for reversing the residual magnetism to the desired extent may be determined by supporting a loud-speaker in a jig at a predetermined distance from a cathode-ray tube. The Provisional Specification describes a method of neutralizing the stray fields by fixing a small magnet, correctly polarized, at the rear of the magnet pot.

Abstract: 686,898. Boat releasing gear. HANSEN, K. E. T. H. Sept. 21, 1951. [Dec. 11, 1950] No. 22146/51. Class 115. In a release device for boats suspended in members h engaging a pair of downwardly inclined pins a mounted on a longitudinal shaft b in the boat and being turnable to an upwardly directed position for releasing the suspension members h, and hence the boat, by turning the shaft b, a release lever n for operating the shaft is mounted freely rotatable in relation to the shaft so that when the release has been initiated the shaft can continue to rotate independently of the release lever. The shaft is journalled in plates d hooked upon and clamped to the hoisting hooks e in the boat, and is normally retained against turning from the full line position of Fig. 2 by means of a cam s on the shaft engaging a stationary abutment v on the plate d and being held against the latter by a pawl g engaging a recess in the cam. A sleeve m mounted freely rotatably on the shaft carries the release lever n and a hook o which engages over a projection p on the pawl to hold the latter in said recess. When the release lever is turned the hook is moved from the projection to release the pawl and a cam t on the sleeve engages the lower side of the projection p to lift the pawl clear of the cam s. A projection u on the sleeve then engages the cam s so that the shaft b turns with the lever n. Continual rotation of the shaft to the dash-and-dot-line position of Fig. 2 takes place spontaneously due to the pull of the suspension members h in the deflected ends a of the shaft, the cam s being free to leave the projection u so that the sleeve and release lever are left free.

In a vehicle-heating apparatus, engine coolant flows through a pipe 8, from a pipe 5 interconnecting the cooling jacket of the engine 1 and radiator 2, to at least one heater 7 for heating air to be passed to the vehicle interior and windscreen and then returns by a pipe 9 to the cooling circuit. Moreover, the heat of this coolant is boosted by passing coolant from the engine jacket or, as shown, from the pipe 5 or by an alternative connection 22 from the pipe 8, by way of a pipe 11 to a tank 10 and pump 19 to be heated in a jacket 13 on the exhaust pipe and thence passed to a thermally controlled valve 16, which, if the coolant is hot enough, directs it to the pipe 8, but, if it is not, diverts it through a pipe 18 back to the tank. The pump 19 may be interposed between the jacket 13 and valve 16. To prevent coolant flowing from the booster system back to the cooling system before it has passed through the air heater 7, there are non-return valves 20 in the pipe 8 and in the feed to the tank 10.
