Title: Improvements in or relating to crash operated electric switch devices
Inventor: CORFIELD ALBERT HENRY
IPC: H01H35/14
Filed: 1953-03-05
Abstract: 745,539. Switches operated by impact. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 5, 1954 [March 5, 1953], No. 6190/53. Class 38 (5) A crash - operated switch device has a spring-biased control member normally projecting beyond the skin of an aircraft, a second member which is usually caused to project from the skin when the control member is moved into the interior of the aircraft by contact with an obstruction, and a frangible or distortable switch unit which is distorted or broken if the projection of the second member is prevented. n one form, the control member 25 is pivoted at 19 and is biased by a spring 27 to the Fig. 1 position so that a link 15, connected thereto by a link 18 and bell-crank lever 20, tilts a lever 7 clockwise to hold closed the second member 29. which is pivoted at 30. If the member 25 is pushed inwards, the lever 7 is moved counterclockwise, thereby tripping a latch 8 so as to allow a frame 4 carrying the switch unit 36 to swing to the Fig. 2 position, the member 29 having been moved by a spring 32. If the member 29 is prevented from moving by an obstruction, as would be the case in the event of a crash. the unit 36 will strike the member and will be broken or distorted so that the switch contacts close. The switch unit described is similar to that of Specification 716,504. In a modification, Fig. 7, the unit 36 is stationary and a toggle linkage 53 is connected to the lever 7 and member 29 so that if the latter opens the toggle is straightened but, if not. the toggle is bent further so that the unit 36 is fractured by a striker 54. Specification 574,947 also is referred to.

Title: Improvements in or relating to the treatment of wool
Inventor: EARLAND CHRISTOPHER
IPC: D06M11/30
Filed: 1951-03-14
Abstract: Materials consisting wholly or partly of wool are shrink- or felt-proofed by treatment in an aqueous bath containing a water-soluble chlorite and an aldehyde of the formula RCHO, where R is hydrogen, a CHO group, a carboxyl group, an alkyl or unsaturated alkyl or aryl group or a substituted alkyl or aryl group, which aldehyde is free from amino groups, the pH of the bath being between 4-9 and the temperature between 0 DEG -100 DEG C, and the concentration of the chlorite and the time of treatment being such that between 5 per cent and 30 per cent of chlorite (calculated on the weight of material under treatment) disappears from the bath during the treatment.  In a modification, the chlorite and aldehyde are employed in separate baths maintained under the same pH and temperature conditions, the material being passed through both baths in succession and in either order. Preferred chlorites are those of the alkali and alkaline earth metals.  In Examples the following aldehydes are employed: formaldehyde, glyoxal, benzaldehyde, acetaldehyde, lauryl aldehyde, phenyl acetaldehyde, n-heptaldehyde glyoxylic acid, 8-hydroxy valeric aldehyde, vanillin, isobutyraldehyde, chloral hydrate, crotonaldehyde, acrolein and n-butyraldehyde.  The desired pH is obtained by buffering with sodium acetate, acetic acid, sodium dihydrogen phosphate and sodium hydroxide.

As shown, the opening of the emergency valve 30 enables air to pass from the secondary manifold 32 into branch line 52 to operate the valve 54 and branch line 122 to disengage the clutch 24. Air is also allowed to pass into a branch line 60 which is in parallel with some of the valves in the valve block to move some of the components to a desired rest position so that for example the moulds are opened on operation of the emergency valve. An accumulator 34 is provided in the secondary air manifold 32 so that the emergency valve can still operate in the event of total pressure failure. In addition to manual operation the emergency valve 30 can be operated by pressure in line 46 activated by a valve 50 provided with a manually operated plunger and which is located on the machine at a position remote from the valve 30. In a modification (Fig. 8) of the above described apparatus which is only capable of shutting down a single section at a time means is provided to shut down the whole machine. The line 46 is here in two sections 46a, 46b joined by a shuttle valve 200 so that the section 46a can be pressurized not only by operation of the valve 50 but also by pressurizing a manifold 206. Pressurizing the manifold 206 causes the shuttle valve 200 to establish communication between the manifold 206 and the line section 46a. The manifold is itself pressurized by activating any one of the machine emergency valves (218, 218a,...) each of which is located in a branch line 212, 212a, 214, 216.
