Filed: 1975-01-22
Abstract: 1499724 Gas turbine ducted fan engines; acoustic ducts GENERAL ELECTRIC CO 22 Jan 1975 [15 Feb 1974] 2762/75 Headings F1B, F1C, F1G and F1J The invention relates to an acoustic duct and is described with reference to the fan duct of a gas turbine ducted fan engine. The duct has an asymmetric, peripherally discontinuous acoustic lining 20 attached to the inner surface thereof for absorbing sound propagating within the duct. The lining is so located as to alter the direction of sound emitted from the end of the duct and to obtain preferential enhanced suppression of sound in at least one pre-selected angular sector of the directional pattern. In the embodiment shown it is stated that with the acoustic lining at the upper 180 degrees arcuate surface of the duct noise suppression to an observer on the ground is enhanced. In a second embodiment the upper half of the inner surface is lined with one acoustic material 20 such as fibrous material and the lower half is lined with a second acoustic material 22 such as honeycomb, resonant chamber panel material, the first material having a higher sound absorption coefficient than the second material. In Fig. 5 which represents the exhaust duct of an industrial gas turbine plant, there are two arcuate strips 24a, 24b of the same acoustic material disposed at the lateral inner surfaces of the duct.

Patent GB-524341-A (GB)
Title: Improvements in or relating to routine test equipment for electrical circuits
IPC: H04M3/08
Filed: 1939-01-27
Abstract: 524,341. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and PETERS, G. E. Jan. 27, 1939, No. 2893. [Class 40 (iv)]  An automatic routine tester is provided with arrangements for making a permanent record, e.g., by printing, of the identity and nature of the fault of faulty equipment. The circuits shown comprise an access switch AC to the banks of which units UTC to be tested are connected, a test sequence switch TS and a sequence switch SP for controlling the operations of the printer PR which may be that described in Specification 517,296. The test described is for the operation and release of relay TC. When the access switch seizes the unit, test sequence switch TS is standing on its first contacts and TC should operate so that T pulls up, steps TS and falls back, whereupon TC should release and T pull up again to step TS. When the test on UTC is completed, TS restores to normal in known manner and AC is stepped on to the next UTC circuit. If due to the non-operation of TC, T does not pull up in position 1 of TS, a threeseconds interrupter T1 operates FC which connects battery over relay PNS to the start lead STL of timepulse circuit TPS, PNS remaining inert until operated by a pulse on ZL whereupon it locks up. PNS energizes the back-stroke magnet TSM of the test switch and PN pulls up over contacts pmc of the printer magnet PM to mark bank PS of the printer switch over tsm3 and spm3 and to make a selfinterrupting circuit for the printer switch PSM. When this switch, which also carries a printing drum, reaches the marked contact, PT energizes the printing magnet PM which records the nature of the fault. The magnet also releases PN which releases PT followed by the magnet, and printer sequence switch SP takes a step. Relay PN pulls up again and marks over lead SPC a blank space on the printer which thus only advances the tape. Switch SP takes another step, and PN marks over acm3 the printer contact corresponding to the tens digit of the tested unit UTC which is printed in similar manner followed by the units digit marked over acm4 in position 4 of SP. If two stages of access switches were necessary further digits would be printed in accordance with the position of the access switch of the other stage. When SP reaches position 5, PNS is shunted down and TS takes a step to perform the next test. The printer may be common to a number of routiners of different types in which case it would also print information as to the type. The invention may be applied to repeated testing arrangements for a single circuit and to the testing of a sequence of operations of a machine which for this purpose is provided with contacts to give indications to the testing equipment.

Title: Electrical program switch assembly
IPC: H01H43/12
Filed: 1966-01-25
Abstract: 1,135,734. Time switches. CROUZET S.r.l. 25 Jan., 1966 [20 Feb., 1965], No. 3324/66. Heading H1N. A programming switch suitable, for example, for washing machines, comprises a continuous drive and a clutch which is actuated intermittently by the drive itself to step a cam bank and which may be actuated for longer periods by means coupled to the cam bank to provide rapid advance, for example, over portions of the programme to be omitted. A synchronous motor (not shown) drives input shaft 9 and thereby rotates a wheel 7, carrying cams 7c and 18, continuously. Cam 7c operates contacts (not shown) for conventional reversal of an impeller, for example, while a lobe 18a on cam 18 closes contacts 14, 15 to energize a solenoid 10 briefly at regular intervals. Armature 11 of solenoid 10 slides wheel 7 axially to engage clutch teeth 7d thereon with teeth 5a on a cam bank 5 which is thus turned through a small angle. A ratchet wheel 21, integral with cam bank 5 and co-operating with a locating pawl 19, immediately closes contacts 28, 29 (Fig. 2) in parallel with contacts 14, 15 (as in Fig. 3, not shown) thereby maintaining the clutch engaged until pawl 19 locates a completed step of the cam bank and contacts 28, 29 are opened. Stepping continues until a cam track 24a on a programme control disc 24, coupled to the cam bank 5, closes contacts 26, 27 (in parallel with contacts 14, 15) and holds the clutch engaged for rapid advance of the cam bank as long as the contacts 26, 27 are closed. Change of programme may be effected by altering the relative angular position of disc 24 and cam bank 5 or by changing the disc 24 for one with a different cam track 24a. Additional step-initiating contacts may be actuated by cam 18 (Figs. 4 and 5, not shown), or by extra cams (18<SP>1</SP>, 18<SP>11</SP>, Figs. 6 and 7, not shown) and thus different stepping rates may be selected by manually-operated switches (30a 31a, Figs. 4 and 6, not shown), or automatically determined by an additional cam track (24b, Figs. 5 and 7, not shown) on disc 24 which acts on further contacts (33, 34, 35).

Title: Synthetic cross-linked polymers
Inventor: PHILLIPS LESLIE NATHAN
IPC: H01B3/44
Filed: 1964-01-28
Abstract: Cross-linked polymers are prepared by reacting a polymer that contains aromatic nuclei which are not substituted by strongly electron withdrawing groups with an aralkyl ether that has two methoxymethyl groups each attached to an aryl group to eliminate as methanol, hydrogen atoms from aromatic nuclei in the polymer and methoxy groups from the aralkyl ether, whereby a cross-linked polymer is produced with the remaining part of the aralkyl ether crosslinked directly between aromatic nuclei in the polymer.  The cross-linking process is particularly applicable to polymers prepared by reacting a compound that contains at least one aromatic nucleus per molecule with an aralkyl compound that has two groups, each of which is either a methoxymethyl, chloromethyl, bromethyl or iodomethyl group and each being attached to an aryl group in the aralkyl compound, so that hydrogen atoms from aromatic nuclei in the compound and methoxy groups or halogen atoms from the aralkyl compound are eliminated as methanol or hydrogen halide to form a polymer by inter-linking the remaining part of the aralkyl compound between aromatic nuclei in different molecules of the compound.  Suitable compounds for preparing the preferred polymers are lower polyphenyls, fused ring aromatic hydrocarbons e.g. naphthalene and triphenylene, aryl or phenyl esters of inorganic acids e.g. triphenyl phosphate, low molecular weight aryl siloxanes e.g. octaphenylcyclotetrasiloxane, aryl substituted borazoles e.g. N-triphenyl borazole, metallocyclopentadenyl sandwich compounds e.g. ferrocene, resorcinol, diphenyl-diphenoxysilane, diphenyl oxide and carbazole.  Other suitable polymers for cross-linking are polyesters e.g. those prepared from terephthalic acid and polyphenyl glycols, polymers obtained by the self-condensation of benzyl chloride and polystyrene. The preferred aralkyl ether is p-di(methoxy) xylylene and the cross-linking process may be carried out in the presence of a Friedel-Crafts type catalyst, preferably stannic chloride.  The cross-linked polymers may be used to impregnate asbestos felts for the production of laminates and to impregnate a thin sheet of asbestos paper for the producing of a resistance thermometer (see Divisions B5 and H1).

Title: Hydraulic load lifting system

Filed: 1976-01-30
Abstract: 1482399 Valves CATERPILLAR TRACTOR CO 30 Jan 1976 [27 May 1975] 03833/76 Heading F2V [Also in Division F1] In the circuit shown, Fig. 1, lifting rams 12 are provided with vented check valves 33, 34, and in order to prevent hammering and momentary load drop when a control valve 21 is moved to the lowering position, a valve 48 is included in the circuit which pre-pressurizes the control line 27 prior to venting the check valves and moving the control valve 21 to the lowering position. To lower the load a pilot control valve 52 is manually shifted to direct pilot pressure to the valves 48, 21. Less pres. sure is required to move the spool 63, Fig. 2, of the valve 48 than that of control valve 21. Thus, spool 63 is moved so that annuli 65, 70 are connected through passages 80, 81. This connects the head ends of rams 12 to the line 27 via orifices 44, Fig. 5, of check valves 33, 34, control chambers 42, lines 86, 87, vent line 69, passage 70 of valve 48 and connector line 71. This pre-pressurizes the line 27 and equalizes pressure on opposite sides of the check valves. Metering passages 80, 81 modulate this prepressurization. As the pilot pressure increases, the spool 63 of valve 48 is moved to its fully displaced venting position, Fig. 4 (not shown). An annular passage 77 and a metering slot 78 modulate the venting of the check valves. Immediately after the check valves are fully vented the control valve 21 is opened to lower the load. A check valve 73, Fig. 2, prevents loss of pre-pressurization when spool 63 moves to its venting position. A relief valve 84 prevents pressure build up when the control valve 21 closes. It opens at a pressure below that at which relief valve 30 opens. Opening of valve 84 prevents the check valves closing by continuing to vent them and this enables relief valve 30 to open. Devices 88 provide equalization between the two rams 12 and ensure simultaneous closing of the check valves.
