Filed: 1975-04-17
Abstract: 1531460 Energy absorbing devices IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 6 April 1976 [17 April 1975] 15965/75 Headings F2S and F2V An energy absorber comprises a compressible body comprising a plurality of deformable hollow members embedded in a matrix of resilient material and a piston movable to compress the body thereby to absorb energy from the piston on movement thereof. The absorber may be used in a pressure relief valve, e.g. in a flight terminator in a rocket, the piston constituting a valve opening member. A valve (Fig. 1) consists of the absorber 20 between the piston 12 and end cap 18, and has an opening 14 through which pressure can be vented on release of 12 by a remote control 16 whereby 20 takes up the energy from piston 12. The hollow members may be of glass, and the matrix may be an elastomer. The compressible body may have a deformable reinforcement member embedded therein and the member may be extruded aluminium of honeycomb crosssection.

Title: Improvements in or relating to thermionic valve circuits
IPC: H04N5/52
Filed: 1938-05-30
Abstract: 515,363. Television. HARDWICK, J. May 30, 1938, No. 16083. [Classes 40 (iii) and 40 (v)] A thermionic valve 16 with at least three electrodes functions as a switch on the application of switching pulses which are derived from controlling pulses by passing the latter through a coupling 17, 18, 19 which renders the switch conductive only after the termination of the controlling pulses. Each synchronizing or other controlling pulse is differentiated by the .transformer to afford two pulses of opposite sign from the leading and trailing edges respectively of the synchronizing pulse, and the valve is rendered conductive by the pulse generated by the trailing edge. The synchronizing pulses are followed by datum portions (e.g. black) and the valve connects a condenser 24 and resistance 25 to a lead 14 to stabilize the potential of the television signals and provide a gain-controlling potential. According to a modification, two valves are connected back-to-back and have the switching pulses applied to them simultaneously to serve as a two-way conducting switch, and a potentiometer is connected between the anode of one valve and the cathode of the other for balancing, Fig. 2 (not shown). Specifications 456,450 and 458,585 are referred to.

Title: Liquid sealing device for packing the shaft of a turbine or compressor
IPC: F01D11/06
Filed: 1955-06-07
Abstract: 780,537. Stuffing-box substitutes. AKT.- GES. FUR TECHNISCHE STUDIEN. June 7, 1955 [June 19, 1954], No. 16350/55. Class 122 (5). A liquid sealing arrangement for packing the shaft of a turbine or compressor, particularly in a closed cycle thermal power plant wherein a gaseous working medium circulates under variable pressure depending on operating load conditions, comprises a chamber 5 sealed from the atmosphere by a liquid seal 4 and communicating through a restricted flow path with a second chamber 6 supplied with working medium which is maintained at a pressure above the pressure in the first chamber by a differential pressure actuated valve 15. The shaft 2 of the turbine of a power plant is provided with spaced labyrinth packings 7, 8 and the chamber 6 between the packings is supplied through ducts 9, 10 and 11 with sealing gas from a point in the plant circuit at a pressure higher than that in the turbine outlet 3. The chamber 5 is connected by conduits 12 and 13 to a container 14 in which the pressure is maintained at a value lower than that in the chamber 6 by means of the valve 15 biased to close by the pressure in duct 10 and to open by the pressure in the container and a tension spring 18. When the valve 15 is open, gas escapes via a duct 19 from the container 14 until a predetermined pressure difference exists between the chambers 6 and 5. Sealing gas in the chamber 6 therefore flows through the packings 7 and 8 towards the turbine rotor 1 and to the chamber 5 respectively and gas leakage from the latter is prevented by lubricating oil fed under pressure through a duct 20 to the combined bearing and oil seal 4, A pump 21 draws the oil from a reservoir 22 and delivers it to the duct 20 via ducts 23 and 27 and a throttling device 26 comprising two interconnected pistons 28, 29, the space below the piston 28 being connected to the duct 27 by a duct 30 and the space above the piston 29 being connected by a duct 31 to the container 14. The pistons are urged downwardly to open the duct 27 by a spring 32 so that the pressure in that duct always exceeds by a predetermined amount the pressure in the container. Lubricating oil is also supplied from the duct 27 via a duct 42 to the compressor bearing 33 and the compressor shaft 35 is sealed in a similar manner to the turbine shaft by sealing gas fed from the duct 10 to a chamber 41 between labyrinth packings 39, 40. The level of oil in the container 14 is maintained constant by a spring loaded valve 44 that is opened by the oil pressure in duct 47 when the float rises to a predetermined height and closes outlet 51 from the space under the valve piston 49, oil then returning via duct 45 to the reservoir 22. The throttle device 26 may be loaded by a weight instead of by the spring 32.

[Class 7 (iv)] Discharge of the condenser C2 across the series spark-gap G is initiated by a voltage supplied to a third electrode in response to current flow in the condenser-charging circuit. A transformer P, the primary winding of which is in the condenser-charging circuit, and the secondary connected to the third electrode, may be used. The voltage-initiating discharge may be that applied to a gap F in the condensercharging circuit, an impedance R2 being used to prevent continuous discharge. If the voltage at the gap F is insufficient, it may be increased by using an additional winding on the transformer L1.

Patent GB-744050-A (GB)
Title: Improvements relating to nylon mouldings
Inventor: DOWNES DOUGLAS GEORGE
IPC: C08J7/02
Filed: 1952-07-01
Abstract: The dimensional stability of nylon mouldings is improved by boiling the article in water or other absorbable liquid, e.g. benzene, which is a non-solvent for nylon, until there is no further increase insize and then drying the article to remove almost all of the absorbed liquid.  The final liquid content in the case of water should be at least 0.25 per cent by weight.  The absorbed liquid should be removed almost to the extent such that an oily liquid bleeds from the surface.  The drying may be started on a test sample shortly before starting on the moulding and drying stopped when the sample bleeds. The absorbed liquid should boil at a temperature high enough to ensure that voids in faulty mouldings will burst by expansion of the trapped gas.  If the article is to be machined the boiling and drying treatment may be performed after machining but preferably is performed before and after machining.  In an example, nylon mouldings of 1 inch diameter and 1/4 inch thickness are rough machined, aged for five to six weeks while being protected from ultra-violet and infra-red radiation, boiled in water for four hours and then desiccated in an air oven at 100-115 DEG  C. for forty-eight hours. The mouldings are then immersed in oil.  When required for machining they are cleaned in benzene, machined, and the boiling and desiccating treatment repeated.  The articles are then re-immersed in oil until required for use.  The oil is stated to physically transform the surface to render it impervious to water.
