Patent GB-336754-A (GB)
Title: Improvements in the art of compressed products
IPC: C08L97/02
Filed: 1929-09-20
Abstract: 336,754. Halizite Corporation, (Assignees of Hawerlander, A.). March 13, 1929, [Convention date]. Moulds.-Compressed fibrous products are made from materials such as sawdust etc., by first treating the fibrous material with a small amount of a volatile liquid such as petrol and then incorporating the treated material with sufficient phenol formaldehyde resin condensation product to cover the surface thereof, and subsequently subjecting the mass to heat and pressure using moulds with vents to allow the whole of the volatile liquid to escape before the binding agent hardens. Blocks having the appearance of wood are made by coating a sheet of veneer first with petrol and then with binding agent, placing this at the bottom of the mould, filling the mould with prepared sawdust, placing a second sheet of veneer on top and pressing. Example: About 1,000 grams of sawdust are spread upon a table and about 100 ccs of petrol are sprinkled evenly thereover after which the sawdust is treated with 100 ccs of liquid resin binder, and is placed in a steel mould having vents therein. The mould is closed and subjected to a temperature of 400 F. at 1,500 lbs. per square inch pressure for about 15 minutes.

Filed: 1959-08-21
Abstract: 906,512. Automatic voltage control systems; inductors. MULTITONE ELECTRIC CO. Ltd. Nov. 16, 1960 [Aug. 21, 1959], No. 28697/59. Classes 38 (2) and 38 (4). [Also in Group XL (c)] In a transistor amplifier (see Group XL (c)), the first stage draws its power from and so modulates the amplitude of oscillation of, the second stage which comprises an oscillator. In one modification the transistor oscillator T10, Fig. 4, draws its supply from the collector circuit of a transistor rectifier T11, via resistor R18, rectifier X2 and smoothing condenser C10, providing a D.C. negative feedback circuit which maintains the mean amplitude of oscillation constant. In a modification (Fig. 5, not shown) in which the oscillator is followed by a high-frequency amplifier, the mean amplitude of oscillation is maintained constant by feeding the oscillator from the negative supply via a resistor and from the collector circuit of the high frequency amplifier via a rectifier. A mechanical negative feedback arrangement may also be used; in this the rectified output current of the system is passed through a moving coil C working in the gap of a magnet A and operating a recording stylus G. The moving coil C is also coupled to a nickel silver disc H which provides variable damping on the oscillatory circuit which is wound on a ferrite core K.
