Title: Power supply units for road vehicles
Inventor: ROYLE ANTONY PETER
IPC: H02J9/06
Filed: 1965-08-25
Abstract: 1,100,640. Systems depending on two supply sources; inverters. JOSEPH LUCAS (INDUSTRIES) Ltd. 25 Aug., 1966 [25 Aug., 1965], No. 36449/65. Headings H2F and H2H. A road vehicle comprising an A.C. load 41 such as a refrigerator is provided with means so that whilst the vehicle is in use the load is supplied from the battery of the vehicle by way of an inverter and that whilst the vehicle is in a depot the load may be supplied from an A.C. mains source. The vehicle battery is connected to terminals 11, 12 and whilst the vehicle is in use contact D1 of a relay D is normally closed. Assuming the thermostat of the refrigerator 41 and a master switch 42 to be closed relay B is energized to close contacts B1 B2. Closure of contact B2 energizes relay A to change over contacts A1, A2 whereby the load 41 is connected to the output transformer 48 of an inverter which includes transistors 46, 50. The inverter is driven by an oscillator, including transistors 35, 36, the energization of which oscillator is also effected by closure of contact B2. When the vehicle is out of use in a depot an A.C. mains supply is connected to terminals 13, 14 whereupon a relay C is energized to open contact Cl, thus de-energizing the driving oscillator and the relay A. Contacts Al, A2 revert to the normal positions shown in the Figure, the load 41 then being supplied from the A.C. mains. The oscillator transistors 35, 36 are protected by Zener diodes connected between emitters and collectors, the inverter transistors 46, 50 being similarly protected but with resistors in series with the Zener diodes. The system also contains two further transistors 19, 25 arranged in a Schmitt trigger configuration which is effected to cause energization of relay D when the voltage of the vehicle battery is low. The subsequent change-over of contact D1 prevents the load from discharging the battery further and sounds an alarm 43. Means may also be included in the circuit to prevent energization of the relay D whilst the vehicle engine is being started and also to prevent starting of the engine whilst terminals 13, 14 are connected to the A.C. mains.

Title: Apparatus for regulating the varying humidity of an ambient atmosphere or the moisture content of the ground
IPC: A01G25/16
Filed: 1959-10-30
Abstract: 903,705. Hygrometric apparatus. FRAMPTON, R. C., and LOWNDES, D. B. Oct. 27, 1960 [Oct. 30, 1959], No. 36844/59. Class 97 (3). [Also in Groups XII and XXIX] Apparatus for regulating humidity of an ambient atmosphere or the moisture content of the ground by controlling the supply of water to distributing devices, such as seed or plant irrigators, in dependence upon evaporation and rainfall consists of a porous block or fabric wick 2 in a well 1 which is connected by a tube 4 to a vessel 6 housing a float 7 depending from an open tank 9 having a syphonic discharge pipe 10 and a valve disc 14 that co-operates with a nozzle 13 connected by a pipe 16 to a valve 17 controlling flow through a pipe 18 leading to distributing devices in the air or ground. Normally, the liquid in the vessel 6 lifts the float 7 to urge the disc 14 against the nozzle 13, the liquid level in the well 1 being the same as in the vessel 6. Upon evaporation of liquid from the well 1 the level in the vessel 6 falls, the float and tank being thereby lowered so partially opening the nozzle 13 and allowing liquid from the pipe 18 to enter the tank 9, the resulting increased weight of which then further lowers the float and tank: the reduction of pressure in the pipe 16 opens valve 17 to permit liquid to flow to the distributing devices. The water level in the tank 9 rises until it is discharged through the pipe 10 into the vessel 6 and well 1; the float and tank rise until the nozzle 13 is again sealed by the disc 14, whereupon the valve 7 is closed. Rainwater may also be supplied to the tube 4 from an annular reservoir 23 around the well 1; the reservoir, which is provided with a rain collector 20, discharges into the tube 4 under the control of a float-actuated valve 29. The float 25 and float 26 are arcuate.

Title: Method of producing shell moulds by the croning shell process
IPC: B22C23/00
Filed: 1971-08-05
Abstract: 1307176 Foundry moulding processes and patterns DEUTSCHE EDELSTAHLWERKE AG 5 Aug 1971 [1 Sept 1970] 36963/71 Heading B3F A method of moulding a shell mould comprising two parts one of which is provided with an ingate includes supplying resin-impregnated sand to a heated pattern 3 provided with an ingate-forming member 1, removing surplus sand from the pattern, curing the mould part formed on the pattern in a store and removing at least part of the ingate-forming member 1 from the ingate 8 formed before ejecting the mould part with its integral ingate 8 from the pattern plate. The mould part with the integral ingate is then joined to a mould part without an ingate. In Fig. 1 the ingate-forming member 1 is in two parts 2, 4, a cylindrical part 2 which may be permanently fixed or may be detachable from a pattern plate 3 and a frustoconical part 4 which is detachably connected to part 2 by e.g. a snap connection 5, a permanent magnet, screw or key. Before ejection of the mould part from the pattern plate only the part 4 is removed from the ingate 8 by a handle 6. In Fig. 2 a one-piece ingate-forming member 1 is employed attached to a pattern plate 3 by a permanent magnet 9 and provided with a blind bore 11 into which enters a long ejector pin 10. Movement of a thrust plate 13 upwards forces the ejector pin 10 to remove the member 1 from the ingate 8 and further upward movement of the thrust plate 13 contacts an ejector plate 14 which forces ejector pins 15 thereon to remove the mould part from the pattern plate 3. Although not shown this method of ejection can be employed with a two-part ingate-forming member (1) as in Fig. 1, the long ejector pin (11) serving to remove only the frusto-conical part (4) from the ingate (8). In order to facilitate removal of the ingateforming member it may be provided with a cover-plate (not shown) extending peripherally beyond the widest part of the frusto-conical part to a pointed peripheral edge.

Title: Receiver for centralised controlling apparatus
IPC: H02J13/00
Filed: 1971-08-06
Abstract: 1317066 Ripple current signalling receivers MITSUBISHI DENKI KK 6 Aug 1971 [20 Aug 1970 21 Aug 1970] 37103/71 Heading H4R In a receiver for detecting A.C. signals superimposed on a distribution system a mechanical resonator is arranged to respond to the superimposed signal and cause a voltage to be induced in a detector coil. The induced voltage causes triggering of a switching device to actuate a relay controlling supply of power to a load. As described a supply on terminals 1S, 2S, if it contains a superimposed signalling frequency causes circuit 1, 2, to resonate. The coil 2 is wound on a core 3, Fig. 2, and causes oscillation of a resonant reed 4 to cause variation in the flux in the auxilliary magnetic circuit including the reed 4 a permanent magnet 8 and a core 7 carrying the detector coil 6. Variation of flux in the auxilliary circuit causes generation of a voltage in coil 6. Fig. 1, and firing of a thyristor 9. Current through thyristor 9 flows through the heater 12 of a bimetallic element 14 movement of which, in response to heating closes the switch 13 supplying power to a load connected to 1L, 2L. In an alternative arrangement, Figs. 3 and 4 (not shown), the magnetic core (3) carries two auxilliary magnetic circuits and resonant reeds (40, 50) resonant at two different frequencies. The respective detector coils (44, 53) fire respective thyristors (62, 63) to cause heating of respective bimetallic elements (19, 20) movement of which cause operation of a change over switch (190) in one direction or the other dependent upon which bimetallic element is heated, the switch staying in its operated position until a signal of a frequency to operate the other bimetallic element is received.
Patent GB-912688-A (GB)
Title: A process for the oxidation of hydrocarbons
Filed: 1960-10-31
Abstract: An olefinic hydrocarbon having 3 or more carbon atoms is oxidised to an a .b -unsaturated aldehyde or ketone by passing concurrently the olefinic hydrocarbon vapour, a molecular oxygen-containing gas and a heavy metal-containing oxidation catalyst through an elongated reaction zone which is in open communication with a catalyst-containing zone of cross-sectional area larger than that of the reaction zone, the reaction system being preheated by passing a heated inert gas at controlled rate through the zone of larger crosssectional area and into the reaction zone so that at least a substantial part of the catalyst is maintained in the catalyst-containing zone in the form of a fluidised bed while some is entrained in suspended form in the reaction zone.  The entrained catalyst may be separated from the gaseous effluent from the reaction zone and passed to the catalyst-containing zone.  The heated inert gas is preferably hot hydrocarbon combustion products obtained by burning a hydrocarbon gas in a suitable combustion zone.  Preferably at least part of the gaseous effluent from the reaction zone is passed through a cooling zone to the catalyst-containing zone.  The reaction zone is generally maintained at a temperature in the range 350-550 DEG C. and at a pressure from atmospheric up to 500 lbs./sq. inch.  A paraffinic hydrocarbon gas, e.g. propane, may be present in the reaction mixture.  Suitable catalysts are, for example, tellurium oxide alone or in combination with an oxide of molybdenum, tungsten or uranium; copper oxide in combination with a metal of the palladium-platinum group or with Group VIII elements of the fourth series; silver, lead, iron, cobalt, nickel or cadmium selenites or tellurites; copper in combination with silica gel containing in addition cadmium, cobalt, molybdenum, thorium, manganese, calcium or titanium; selenium in combination with an oxide of copper, vanadium, tellurium, chromium, molybdenum, tungsten, uranium or tin; or combinations of selenium with copper aluminate or silicate.  The preferred catalysts are those containing an oxide of molybdenum, especially bismuth molybdate further modified, if desired, by the addition of phosphorus or phosphorus compounds.  A suitable catalyst is bismuth phosphomolybdate in combination with an aluminous or siliceous catalyst support.  An example is given of the oxidation of propylene to acrolein using a bismuth phosphomolybdate catalyst. Specifications 912,686 and 912,687 are referred to.  Reference has been directed by the Comptroller to Specification 821,999.

Abstract: 446,201. Prepayment mechanism for meters. MEASUREMENT, Ltd., Terminal House, Lower Belgrave Street, London, and CONNOR, R., and CLIFFORD, C. F., Tameside Works, Dobcross, near Oldham. Dec. 29, 1934, No. 37242. [Class 27] In prepayment meter mechanisms, the consumption meter through wheels a, b, c rotates the planet - carrier d of the usual differential gear, the sun-wheel e of which is rotated by prepayment, the other sun-wheel h rotating the cams i controlling the trip lever j for an electric switch or other commodity supply device. The wheel h is carried by a sleeve k to which a wheel m is secured, the sleeve being mounted on a spindle n carrying the cams i. If no rent charge mechanism is to be used, the sleeve k is secured to the spindle n by a screw, so that the cams i rotate with the sleeve k. When a rent charge mechanism is required in the meter, the sleeve k is free on the spindle n and the wheel m drives a sunwheel o of the rent charge epicyclic gear, the planet carrier p of which is driven by the rent charge motor. The other sun-wheel q drives through a sleeve r and wheel s a wheel t secured to the spindle n. If the rent charge mechanism is not required, it can be removed and the sleeve k secured to the spindle n.

Title: Improvements in or relating to aircraft guidance systems
IPC: G01S1/02
Filed: 1965-09-01
Abstract: 1,127,175. Automatic radio control of aircraft. HONEYWELL Inc. Sept.1, 1965 [Sept. 1, 1964], No.37436/65. Heading G3R. [Also in Division H4] In an aircraft guidance system, a radio beam error signal is modified by a gain control device which is automatically varied in dependence on a comparison between functions of the rates of change of beam error and course deviation to ensure a constant ratio between the magnitudes of modified error signal and course deviation regardless of the distance of the aircraft from the radio transmitter. As described, a signal representative of the vertical acceleration of an aircraft, and derived from elevator deflection or pitch attitude and forward velocity, is integrated and compared with a datum rate of change of altitude to produce a signal dependent on rate of change of altitude error. A signal from a radio receiver representing angular displacement from a gilde-path is applied through a variable gain device and a phase shifter to control the aircraft automatic pilot or give an indication of control necessary by a human pilot. In order to ensure that the signal has a constant magnitude for a given linear displacement from the glide path, regardless of the distance from the radio transmitter, a comparison is made between deviation of the rate of change of altitude from the average rate of change of altitude and the output of the variable gain device. Any difference is automatically nullified by utilizing the difference to control the gain of the variable gain device. Filter, lag, and integrator circuits are incorporated to produce desired response characteristics. Alternative application to the control of an aircraft about its roll axis to maintain it on a localiser beam is referred to.
