Title: Crosslinked loop humidity sensing element and method of making the same
IPC: G01N19/10
Filed: 1969-01-01
Abstract: 1,263,291. Humidity sensing element. JOHNSON SERVICE CO. 1 Jan., 1969 [15 Jan., 1968], No. 144/69. Heading B2E. [Also in Divisions C3 and Gl] A humidity sensing element in the form of a loop made by joining the ends of a strip of material comprises a core sandwiched between moisture sensitive layers. The core material is a fully cross-linked reaction product formed by the reaction of a compound containing glucoside chains such as a cellulosic material and a stabilising monomer. To accelerate the cross-linking reaction a catalyst such as urea-formaldehyde is added to the reaction mixture. A catalyst stabilizer such as an epoxide monomer may also be employed. The outer moisture sensitive layers are preferably formed of cellulose, a cellulose ether or a cellulose ester. To prepare the element, components of the core and the outer layers are separately dissolved in a volatile solvent such as acetone, water or xylene, and the solvent solution of one of the outer layers is cast on a glass plate. After the solvent has evaporated the ends of the film are masked with a solvent resistant tape and the solvent solution of the core material is then cast over the first layer. The masking tape is removed before the solvent of the core solution has completely evaporated and when the core has dried a second moisture sensitive layer is cast over the core. When the three layer film has dried it is heated before being cut into strips which are released from the glass by passing water over the glass. The ends of the strip are then trimmed to leave narrow core free portions at each end which are lapped together in the presence of a weak solvent solution to form a loop. The loop is then mounted on brackets and suspended in a hot alkaline bath to hydrolyze the outer surfaces of the cellulosic outer layers. The bath preferably comprises an aqueous or alcoholic solution of an alkali metal base. The loop is finally rinsed in water. The bath may alternatively comprise a solution of a mineral acid.

Title: Improvements in or relating to the shearing of metal billets into pieces with identical lengths
Inventor: GOLDIE WILLIAM LAW
IPC: B23D21/00
Filed: 1965-01-01
Abstract: 1,096,073. Shearing. LAMBERTON & CO. Ltd. March 31, 1966 [Jan. 1, 1965], No 185/65. Heading B3W. In a method of shearing a billet into pieces of equal length the difficulty of gripping a short length on the last cut is overcome by cutting the discard from the middle of the billet. An apparatus for carrying out the method comprises an eccentric-driven reciprocating shear which has an independently operated hold-down adjacent the movable blade, an adjustable front stop 6, an adjustable back stop 12 and a driven roller table F. Close to the back stop 12 is a photo-cell which senses the presence of a billet and is connected to control mechanism which initiates the shearing cycle. The distance of the backstop 12 from the shearing plane is a multiple of the length of the pieces to be cut. Operation.-A billet to be cut is fed on to the roller table F and moved through the shear until it engages a limit switch in the front stop 6. The hold-down is then operated, the frontstop is moved to an inoperative position and the shear is actuated. The feeding and cutting cycle is repeated until the trailing end of the billet passes the back stop 12 and clears the photo-cell which initiates the discard-cutting cycle. The back-stop 12 is moved into line with the billet and the roller table F is reversed so that the billet is moved against the back-stop and a length equal to the discard overhangs the shear which is then operated. The roller table then drives the billet forward again in the normal cutting cycle, the length remaining being an exact multiple of the required cut length. Beneath the shear are two flaps which are pivoted by pneumatic cylinders to direct cut lengths alternately into one of two bins and the discards into a third bin.
