Filed: 1942-12-11
Abstract: 560,365. Glass manufacture; burners. GREETHAM, E. Dec. 11, 1942, No. 17660. [Class 56] [Also in Group XI] A method of heat treating a glass article consists in subjecting the desired part of the article to a number of gas flames arranged around it, and automatically increasing the size and intensity of the flames in a predetermined manner so as to raise the temperature in desired stages up to the required final temperature. The method may be used for sealing electric lamp bulbs, radio valves, or vacuum flasks, and may be carried out with a substantially annular burner having a number of closelyspaced jets disposed around its inner peripheral surface. A number of such burners 2, Fig. 1, may be spaced equally around a rotating table 1, the glass articles being gripped by holders 4 which are raised and lowered by a cam, as the table rotates, to bring the article into and remove it from the ring of flame from the burner jets. The supply of gas to the burners may be controlled and varied in a predetermined cycle by a valve actuated by any suitable mechanism. Preferably the valve comprises a stationary disc 17 and another disc 18 which is fixed to and rotated with the table 1. The discs have ground faces in contact with one another, and ports are formed in these faces. Gas at different pressures supplied to the ports 21-23, Fig. 4, in the disc 17, and ports I-XII in the disc 18 each of which is connected to a burner 2. Thus as the disc 18 revolves, the ports I-XII sweep over the ports 21-23 and each burner is supplied with gas at increasing pressures. Small " buffer " ports 24-26 are also provided in the disc 17 between the main ports and are provided with gas at intermediate pressures in order to keep the burners alight during the change from one gas pressure to the next. In a modification, the burner unit or head may be stationary, and the operator may stand on a platform that is rotated to carry him past the burner units.

Title: Polyester preparation
Inventor: PORTER KENNETH
IPC: C08G63/78
Filed: 1966-04-22
Abstract: Fibre- and film-forming polyesters are made by polycondensing a bis glycol ester of a dicarboxylic acid or an oligomer thereof, at least part of the polycondensation reaction being carried out while the reaction mixture in liquid state is caused to move along a long narrow tube in a state of turbanular flow by continuous concurrent movement past the liquid of an inert gaseous fluid, the rate of flow of the gaseous fluid being such as to ensure that during at least part of the residence time of the reaction mixture in the tube the partial pressure of glycol in the gaseous fluid is below the equilibrium partial pressure for the reaction mixture with which it is in contact.  Suitable glycols are bis-1:4-hydroxymethylcyclohexane and those of formula HO.(CH2)n.OH where n is 2 to 10.  Suitable dicarboxylic acids are terephthalic acid and bis-1:2-(p-carboxyphenoxy)ethane.  Suitable gaseous fluids are nitrogen and trichlorofluoromethane. The gaseous fluid may contain a substance which reacts with carboxyl end groups, e.g. ethylene oxide or diazomethane. The reaction mixture may be fed to the tube in liquid form or dispersed in a suitable liquid. In the case where the gaseous liquid may be liquefied, the same liquid may be used as that in which the reactants are dispersed.  The tube may be of uniform bore or the bore may increase progressively towards the outlet.  The gaseous fluid may be injected at one point or more than one point. In examples, poly-(ethylene terephthalate) oligomers were fed to a tube the first stage of which was 15 metres long and 2.4 mms. internal diameter and the second stage of which was 7.5 metres long and 6.6 mms. internal diameter, the oligomers being (a) dispersed in trichlorotrifluoromethane, (b) dispersed in trichlorotrifluoromethane and a eutectic mixture of diphenyl and diphenyl oxide and (c) in molten form, nitrogen being used as the gaseous fluid.

Title: Improvements in and relating to ultra high frequency coupling devices and systems
IPC: G01S7/03
Filed: 1945-07-12
Abstract: 597,662. Wave-guides. BRITISH THOMSON-HOUSTON CO., Ltd. July 12, 1945, No. 17879. Convention date, July 17, 1944. [Classes 40 (iii) and 40 (v)] A combined transmitting and receiving system comprising a transmitter and a receiver connected to a common wave - guide has means for protecting the receiver from the transmitter and for preventing received signals of low intensity from being dissipated in the transmitter. Fig. 1 shows an arrangement for connecting a transmitter 1 and receiver 5 to a wave-guide 3 terminated by a radiating or receiving horn 4. The receiver 5 is coupled to the guide 3 through a guide 9 having transverse metallic walls 6, 7, 8 and 12, 13 each formed with an aperture or slot resonant at the operating frequency. The slots in walls 12, 13 are closed by glass windows thus enabling guide 9 to be filled with gas, and electrodes 15 are provided to maintain a small discharge across the tuned apertures in walls 6 and 7. With this arrangement, received waves of small intensity are unable to break down the resonant apertures, and so pass freely to the receiver 5. Waves of great intensity from transmitter 1 break down the apertures and are unable to pass to the receiver. To prevent loss of received energy in the transmitter 2, a gas-filled quarter wave stub 16 is placed at one quarter wavelength beyond the receiver branch guide 9. Stub 16 has a glass covered resonant slot in an end wall 19 which is not broken down by the received energy and so presents a short circuit at onehalf wavelength from 9, thus matching the incoming energy into receiver 5. Transmitted energy 7 however, breaks down the slot in wall 19 so that stub 16 does not interfere with the passage of the transmitted energy. The effect of stub 16 over a wide band is increased by placing a second stub 24, Fig. 3, at a quarterwavelength distance. In this case the stub includes dissipative elements (Figs. 4-6 not shown), so that the reactive circuits of the transmitter always have a resistance in series which precludes the building up of strong resonances. Fig. 8 shows a form of resonant gap 32 formed, between two apertures 33, 34 in a metal wall 29. The apertures may be rectangular (Fig. 8 not shown). Specifications 582,760 and 587,812 are referred to.
