Title: Vehicle having atachments mounted thereon
IPC: E02F9/22
Filed: 1970-06-23
Abstract: 1317615 Scrapers CATERPILLAR TRACTOR CO 23 June 1970 [28 July 1969] 30319/70 Heading E1F [Also in Division F1] A tractor 10a comprises a cushion hitch assembly 19a for connecting the tractor to a goose-neck 18a of a bowl scraper, and pushpull coupling 11 b for connecting the tractor to a second tractor 12b, the assembly 19a and the coupling 11b being actuated by fluid circuits including control valves 43a, 23b respectively, the selective operation of which is controlled by a pilot selector valve 50. The valve 50 has a spool 52 slidably mounted in a housing 51 for movement between positions "A", "B" and "C" by a handle 67, the spool being releasably held in any of these positions by a spring-loaded detent ball 69. In the "A" position pressurized fluid passed from a pump 54 through the valve 50 and conduits 58 and 42a to the valve 43a to move it so that fluid from the pump 54 passes through the valve 50 and a conduit 60a to both the head and rod ends of a cylinder 36a of the assembly 19a to dampen relative movement between the tractor 10a and the scraper. A conduit 57 leading to the valve 23b is connected to the pump reservoir through a conduit 60, whereby the valve 23b passes pressurized fluid from a pump 21b to the rod end of a cylinder 19b of the coupling 11b to maintain a bail 18b of the coupling in a raised position. In the "B" position the operation of the valve 23b is not affected but the conduit 58 is connected to the pump reservoir and the valve 43a is spring-operated to connect the head end of the cylinder 36a to drain while the rod end remains under pressure whereby the bowl of the scraper is lowered. In the "C" position the operation of the valve 43a is not affected but pressurized fluid passes from the pump 54 through the valve 50 and the conduit 57 to the valve 23b to move it so that fluid from the pump 21b passes to the head end of the cylinder 19b while the rod end is connected to drain whereby the bail 18b is lowered to engage the tractor 12b. A spring 65 normally acted against by a piston 64 subject to pressure from the pump 54 will, upon failure of the pump 54, move the spool 52 of the valve 50 to the "B" position. The valve 50 may be modified to include a position in which both valves 43a and 23b are subject to pressure.

Title: Improved cellulosic materials and the production thereof
IPC: D06M15/423
Filed: 1926-12-01
Abstract: 291,473. Tootal Broadhurst Lee, Co., Ltd., Foulds, R. P., Marsh, J. T., Wood, F. C., Boffey, H., and Tankard, J. Dec. 1, 1926. Yarns, treating with liquids.-Textile materials such as yarns and fabrics of cotton, silk, ramie, jute, hemp, artificial silk, acetyl silk, and linen are rendered less susceptible to creasing or crushing while retaining their original suppleness by impregnating them with the components of a synthetic resin and effecting the condensation within the material. In an example, a plain cotton fabric, preferably mercerized with or without tension, is impregnated with a mixture of formaldehyde, urea, boric acid, and water. It is then squeezed and dried at 130‹ C., the excess reagents being removed by a soap boil. The intermediate resin may be employed for impregnating the fabric. Alkaline catalysts such as potassium carbonate, sodium bicarbonate, &c. may be used instead of boric acid. Alkaline catalysts may be employed for the intermediate condensation product, an acid catalyst being employed to effect the final condensation. When phenol-formaldehyde resin is employed, alkaline catalysts may be employed for effecting the intermediate and final condensations, and reducing-agents such as formaldehyde sulphoxylate compounds may be used to prevent development of colour on drying and/or exposure to air and light. In another example, a mixture of acetonephenol condensation product (dihydroxydiphenyl dimethyl methane) and formaldehyde are condensed in the presence of caustic potash by boiling in a reflux condenser. The mixture is then cooled and diluted, for example with formaldehyde and water, and employed for impregnating the fabric. After passing the fabric through rollers to remove the surface liquor, it is heated to 160-180‹ C. to complete the treatment. Specifications 258,357, and 291,474, [Class 42 (i), Fabrics, Finishing &c.], are referred to.

Abstract: 446,176. Printing-machines. FLEISCHHACK, F. K., 3, Oswaldstrasse, Leipsic, Germany. Oct. 23, 1934, No. 30410. [Class 100 (ii)] Make-ready arrangonents.-A make-ready for relief-printing formes is prepared by taking an impression from the forme in a layer of a normally plastic material and then treating the layer with a hardening agent. A plastic material consisting of a mixture of 20 parts by weight of beeswax, 2 parts of petroleum jelly, 15 parts of colloidal graphite, and 5 parts of soft soap is applied to the platen or impression cylinder of the press in a layer sufficiently thick to take a clear impression from all parts of the forme. A sheet of paper is preferably placed over the layer before the impression is taken, and a backing sheet may be provided behind the layer. The impressed layer may be hardened by coating or spraying it with a varnish or treating it with a hardening liquid such as formalin, the liquid being applied to the layer directly or used to impregnate a sheet of paper which is then applied to the layer. When the layer of plastic material is exposed, it may be hardened by dusting with powdered asphalt. If it is desired to avoid very sharp impressions of parts of the forme, e.g. half-tone blocks, thin cardboard insertions corresponding to these parts may be introduced into the make-ready.

Steam-generator &c. furnaces; grates; air supply, regulating.- The space beneath a rotary grate is divided into radial compartments to each of which the supply of air is controlled automatically in accordance with the state of the fuel on the grate section above the compartment. Fig. 1 shows a rotary grate provided with retorts 2 fed by an underfeed stoker 21 and with tuyeres 3 supplied with air from compartments a beneath the grate formed by circumferential walls 4, 5, dipping into water seals, and radial walls. Air under pressure is supplied through the conduit 8 to a stationary annular chamber 9 and passes to the compartments a through dampers 13 operated by the rotation of the grate through rollers 43 travelling on a stationary cam shaped ring 24 and mounted on arms 42 secured to the damper shafts. The wall 4 is provided with openings controlled by dampers 19, 20 controlling the supply of air to compartments a', a<2> conveying air to the innermost portion of the annular grate and to the perforated ring 14 surrounding the opening 15 through which unburnt fuel and ash are delivered on to a rotating grate 22. The latter is supplied with air through a passage controlled by a damper 44 and is sealed at 25. Ashes are removed from the grate 22 by a wiper 23. A water or sand seal is provided between the periphery of the grate and the furnace wall. The ring 15 and the peripheral wall 1 surrounding the grate may be water cooled. Steam or water is supplied to the radial grate sections in those periods when the supply of air is stopped. The grate described may be replaced by a flat or inclined grate or a flat grate may be arranged above the retorts, the fuel being supplied through openings arranged above. In the modification shown in Fig. 3, the grate 26 is shown. arranged in a coking or distillation chamber 30 and with the front wall 29 and bridge 28 may be moved towards or away from the boiler 31 according to the nature of the fuel employed. The arch 36 is provided with fuel charging openings 32, 33, 34 for use according to the position of the grate. In revolving grates fed from above, the grate may be cleared by rotating it at such a high speed that the material thereon is removed by centrifugal force. Fig. 6 shows a grate adapted to be cleaned in this man. ner comprising a central rotating part 45 held stationary while the fuel is pushed on to it from the annular grate 46 which is then rotated at high speed to clear it. The grate section 46 is then stopped and the section 45 is rotated at high speed to distribute the fuel over the entire grate.

Title: Improvements in or relating to masks
Inventor: GREEN JACK RAYMOND
IPC: A62B18/08
Filed: 1960-09-05
Abstract: 912,418. Respiratory appliances. VICKERS RESEARCH Ltd. Sept. 25, 1961 [Sept. 5, 1960], No. 30552/60. Class 81 (2). In a breathing-mask, such as for use for high altitudes, the exhalation valve is controlled by a pressure-sensitive member connected to the inlet, the member having means for delaying its response to pressure changes. Respirable gas is supplied to a mask 6 through a tube 4 and open ducts 5 and vitiated air passes out through an exhalation valve 12 to an outlet 9. However, a capsule 13, having its interior connected through a narrow-bore tube 17 to the supply pipe 4, carries a pressure member 14 which may bear upon the exhalation valve plate 11 to tend to hold it closed. Thus as the supply pressure is increased with increasing altitude an equivalent pressure is applied to the valve 12 to prevent a through flow and consequent wastage of gas. However the exhalation valve may be readily opened by the rapid, slight rise in pressure caused by exhalation of the user since this is not transmitted through the restricted tube 17.

Title: Improvements in and in connection with locking guards or covers for sliver and ribbon lap and like machines
IPC: D01G31/00
Filed: 1919-12-08
Abstract: 164,393. Heywood, C. Dec. 8, 1919. No Patent granted (Sealing fee not paid). Interconnecting guard with starting-gear.-In sliver and ribbon lap machines, derby doublers and the like, a guard extending over the lap roller is connected to a hand lever interlocked with the belt-shifting lever, the guard being adapted to rise as the lap increases in diameter although it cannot be released until the belt has been shifted on to the loose pulley. Conversely the belt cannot be shifted on to the fast pulley until the guard is in working position. The guard a is secured to a shaft d with an arm i connected by links j, k to the operating hand lever m pivoted at n to a bracket o on the machine frame. A rod on the belt-shifting lever passes through a hole p in the bracket o and, when the belt is on the fast pulley, is situated over an arm or extension v of the lever m preventing manipulation of the guard. The joint s of the connecting links j, k is however connected by a link t to the upper end of one of lap racks u, the guard being thereby raised as the lap increases in diameter. When the machine is stopped the guard can be raised by the hand lever m, the arm v then obstructing the hole p to prevent the belt being shifted on to the fast pulley.

Abstract: 1,273,299. Continuous casting. KUIBYSHEVSKY METALLURGICHESKY ZAVOD IMENI V.I. LENINA. 24 June, 1970, No. 30702/70. Heading B3F. In mouldless continuous casting, similar to that described in Specification 1,157,977, in which molten metal before solidification is confined to a required cross-sectional shape by a magnetic field of an inductor 2, in order to restore the transverse dimensions of the molten metal, as they deviate from desired values, the current in the inductor is varied. The desired cross-sectional shape and size are obtained when, in the liquid metal, the electromagnetic forces and the outward pressure due to head of metal are balanced. The inductor voltage being kept constant, by negative voltage feed back, e.g. by a signal from a voltmeter 10, any increase in the height of the liquid metal causes the resistance of the inductor-metal system to decrease and thus increase the inductor current so that there is a self-righting tendency to restrict the metal cross-section. To augment this, a float 13 indicating the liquid metal level provides information for automatic modification of the inductor current. The voltage of the inductor 2 is stabilized by a signal from the meter 10 and a reference from a voltage setter 7, a correction signal resulting from these being passed to a power amplifier 12 by an adding device 9 to determine the supply to a field winding 5 of a frequency changer 4 connected via a transformer 6 to the inductor 2. The value of the metal level becomes, in a converter 14, an electric signal which after modification in units 15, 16 is fed to the amplifier 12.

Title: Sensors for exhaust gases
IPC: G01N27/416
Filed: 1974-07-11
Abstract: 1481421 Exhaust gas sensor ROBERT BOSCH GmbH 11 July 1974 [12 July 1973]  30731/74 Heading G1N A sensor for monitoring nitrogen oxides comprises two electrodes separated by an electrolyte, the first electrode contacting the exhaust gas and comprising a catalyst which reduces nitrogen dioxide and oxygen when a constant potential is applied between the electrodes. As shown, the sensor is attached to an exhaust pipe after an afterburning catalyst and may be continuously or intermittently supplied with exhaust gas via valve 1. The sensor comprises a carbon, diffusion inhibiting layer 2 bounded by two layers 3 of PTFE, and separating the catalyst electrode layer 4 from direct exhaust gas. Electrolyte, preferably immobilized, separates the second electrode 6, which functions as counter and reference electrode, from catalyst electrode 4. Catalyst is preferably a metal chelate of a phthalocyanine, particularly 5, 14 dihydro-dibenzo (5, 9, 14, 18)-tetraaza (14) anulene. The preferred chelates are of cobalt. The catalyst may also comprise carbon, particularly acetylene carbon black or a platinum group metal. Counter electrode may be porous lead or a reference comprising silver/silver sulphate, lead/ lead sulphate or quinhydrone. Electrolyte is preferably sulphuric or phosphoric acid, 4À5N, optionally in a porous inert matrix such as kieselgahr. It may also be an ion-exchange material. Operation The applied voltage is preferably 300-700 mV below that at which the sensor gives a zero output in the presence of oxygen. Preferred values are 200-600 mV preferably 400-500 mV.. When the exhaust afterburner catalyst fails, the NO 2  concentration reaching the sensor rises sharply and so does the sensor output current. This rise may be used to trigger an audible or visible alarm.

Title: Apparatus for identifying a circuit element by generation of an  appropriate element identification code
IPC: H03M7/00
Filed: 1971-06-30
Abstract: 1351981 Selective signalling COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 30 June 1971 [30 June 1970] 30753/71 Heading G4H Apparatus for identifying circuit elements comprises matrix networks G having inputs which receive operative electrical potentials provided by elements E to be identified and outputs q, U, g connected to identification networks arranged to generate an identification code which indicates both a particular element and the matrix network G to which it is connected. Each matrix network (Fig. 2) comprises a diode matrix having twenty-five inputs E 00 ,..., E 24  connected in groups of five to respective outputs q 0 ,..., q 4 ; every fifth input is connected to an output U and all the inputs are connected to a common output g. Receipt of an operative potential on input E 00  of network G 00  produces outputs q 0 , U 0À5  and g 00 . Output U 0À5  energizes the windings U 0À1 , U 5À1  of magnetostatic relays U 0 , U 5  connected to electromechanical relays REU0, REU5 (Fig. 3) while q 0  energizes the winding mqo of a magnetostatic relay MQ 0  which in turn energizes a winding U 5À2  to cancel the effect of winding U 5À1  and thus inhibit relay U 5 . Therefore only relays U 0 , MQ 0  are energized; relay MQ 0  energizes an electro-mechanical relay D 0  which indicates a "tens" index of zero and relay U 0  indicates a "units" index of zero, whence element E 00  is indicated. Element E 0À5  would be indicated by outputs q 1 , U 0À5  to relays MQ 1  and U 0 , U 5  and by output g 00 : relay MQ 1  energizes D 0  and inhibits U 0  by means of a winding U 0À2 . Element E 10  yields outputs q 2 , U 0À5  to relays MQ 2  and U 0 , U 5 : MQ 2  energizes a relay D 1  to indicate a "tens" index of one, and inhibits relay U 5 . In this way any element Eij in a network G may be indicated; the particular network (e.g. G 00 ) is indicated by the output g 00  (Fig. 4) which energizes a relay DG0 or DG1 to indicate a "tens" index of 0 or 1 and also two relays E to provide an indication in a 2 out of 5 code for the "units" index. These relays operate electro-mechanical relays and switches (Fig. 5, not shown), when relays DG0, DG1 produce a "tens" output in 2/5 code, and the outputs may be connected directly to units making use of the information provided. The magnetostatic relays may be replaced by, e.g. toroidal magnetic cores.
