Patent GB-662920-A (GB)
Title: Altitude control system
IPC: G05D1/06
Filed: 1947-03-27
Abstract: 662,920. Automatic altitude control systems. BENDIX AVIATION CORPORATION. March 27, 1947 [April 26, 1946], No. 8369/47. Class 38 (iv). In an automatic craft control system an elevator surface is controlled by means to maintain a predetermined altitude associated with altitude selector means which when operated causes the craft to move to the altitude selected and renders the means maintaining the predetermined altitude inoperative until the selected altitude is reached. With ganged switches 65, 110 in the position shown there is no altitude control, elevator 14 of a craft being only under the control of the pitch channel of an automatic pilot similar to that described in Specification 662,831, in which pitch and follow-up signals developed by inductive devices 26, 16 operate a motor 13 in such a manner as to maintain a pitch attitude dependent on the setting of rotor 28 of inductive device 26. With switches 65, 110 in the other position, constant altitude is maintained in a manner similar to that described in Specification 662,918, the interior of an aneroid 52 being closed from atmosphere by a valve 124 operated by a solenoid 107 energized through switch 110, and the output of an inductive device 62, operated by the aneroid, being connected in series with the pitch and follow-up signals through switch 65 and a relay 114 energized through switch 110. Altitude selection is effected by rotation of a calibrated knob 80 adjusting the angular position of a sector 78, carrying contact segments 75, 76, 77, relative to an arm 71, carrying contacts 73, 74 operated by a wide-range aneroid 67. Rotation of knob 80 from the position shown to select a new altitude results in (a) segment 75 leaving contact 73 to de-energize solenoid 107 and relay 114, thereby rendering altitude control by aneroid 52 inoperative, (b) segment 76 or 77 meeting contact 74 to energize coil 84 or 83 of a two-way relay 90 which selects from the centretapped secondary winding of a supply transformer 95 a voltage to effect change of altitude in the desired sense, and connects it in series with the pitch and follow-up signals. When the selected altitude is attained arm 71 recentres relative to sector 78 and constant altitude is maintained at the new level by aneroid 52. Remote selection of altitude is referred to.

Title: Improvements relating to carbohydrate-derived polymers
Inventor: BIRD TOM PATE
IPC: C07H13/04
Filed: 1965-03-03
Abstract: Polymers of 1,2:3,4-diketals of galactose esterified in the 6-position with an a ,b -olefinically unsaturated mono- or di-carboxylic acid are prepared by polymerizing the corresponding monomeric ester (see Division C2) in the presence of a free radical catalyst.  The ketal residues may then be removed from the polymer by controlled hydrolysis, e.g. in the presence of an aqueous organic acid such as formic acid.  The galactose diketal may be esterified with, for example, acrylic, methacrylic, ethacrylic, a -chloroacrylic or a -cyanoacrylic acid, or maleic, fumaric or itaconic acid or their half-esters. The ketal groups may be derived from acetone, methyl ethyl ketone, methyl propyl ketone, monochloroacetone or cyclohexanone.  Polymerization can be effected in bulk or in benzene using azobisisobutyronitrile as catalyst.  The galactose diketal acrylates or methacrylates may be copolymerized with monomers such as methyl acrylate, methyl methacrylate or acrylonitrile. The polymers after removal of the ketal groups can be converted to acetate, benzoate, phenyl carbamate, phenylhydrazone and phenylosazone derivatives; they may also be nitrated with nitrogen pentoxide, reduced with sodium borohydride to the corresponding polygalactitol-6-ester, and oxidized with chlorous acid to the corresponding galactonic acid polymer (or 1,4-lactone thereof) which can then be neutralized to the salt form, e.g. sodium or calcium salt.ALSO:Esters of an a ,b  olefinically unsaturated polymerizable mono- or di-carboxylic acid and the hydroxyl group in the six position of galactose, specifically diisopropylidene galactose 6-methacrylate and acrylate are novel compounds and are prepared by reacting a ketone with galactose to form a 1,2:3,4-diketal and then reacting with the unsaturated acid.  Acids specified are acrylic, methacrylic, a -chloroacrylic, a -cyanoacrylic, maleic, half esters of maleic or fumaric, a -ethacrylic, itaconic and half esters thereof, and the ketones may be acetone, methyl ethyl ketone, methyl propyl ketone, mono-chloracetone, and cyclohexanone, and a polymerization inhibitor may be present.
