Title: Improvements in radio receiving and like apparatus
IPC: H03J3/10
Filed: 1946-05-20
Abstract: 630,678. Radio receiving apparatus. FELGATE RADIO, Ltd., and HANLET, J. M. N. May 20, 1946, No. 15196. [Class 40 (v)] A high-frequency band-spread tuning apparatus tunable through a plurality of frequency ranges, comprises. an inductance, switch means for selecting successive portions of said inductance, and means for moving a magnetic core to vary the value of the inductance of the selected portions, and a common control means for operating the switch means and for moving the core. The Figure shows an H.F. stage V1 and the local oscillator stage V2 of a superheterodyne receiver. The tunable H.F. circuit includes inductances L1, L2 which are wound end to end on a common former provided with a magnetic core which enters coil L1 first. For medium waves, coils L1, L2 are used together, while the short-wave ranges are covered by sections of coil L1 between the upper end and successive tappings a ... e. A rotary selector switch S connects tappings a ... e successively to earth, and the movable contact is wide enough nearly to cover the gap between successive contacts. Also switch S is controlled by a member which also moves the core into L1 from the upper end. Thus all the time switch S is on contact a the upper section of shortwave coil L1 is in circuit and the core is moved into L1 to give band spread tuning in the highest frequency range. Then switch S engages contact b to move the tuning into the next short-wave range and so on. After leaving contact e, the whole of coils L1, L2 are in circuit for the medium-wave range which is tuned through by moving the core in coil L2 during the remaining 180 degrees travel of switch S. If a third long-wave coil is added, then each section of travel of switch S is only 120 degrees. Identical mechanism controls the circuit of the local oscillator V2 and any other H.F. circuits, all the mechanisms being gangcontrolled.

Title: Liquefaction of gases
IPC: F25J1/02
Filed: 1968-03-29
Abstract: 1,208,202. Gas liquefaction process. PHILLIPS PETROLEUM CO. 29 March, 1968 [31 March, 1967], No. 15262/68. Heading F4P. Cooling of gas, e.g. natural hydrocarbon gas to be liquified is effected by passing pressurized liquid refrigerant, e.g. methane into a flash vaporizing zone 212, Fig. 3, withdrawing at 218 liquid refrigerant from said zone 212 and passing it in heat exchanger at 217 with the feed gas in aline 10 and returning the so-warmed refrigerant to the flash zone 212 using as motive force the difference in density between the cold liquid refrigerant in the flash zone and the partly vaporized refrigerant in the heat exchanger, and which transfer is referred to as thermo-syphoning. The refrigerant methane cycle comprises a three-stage compressor 200 which discharges methane at 585 p.s.i. through a line 201, a heat exchanger 42, Fig. 1, cooled by propane, a line 203, a heat exchanger 204 cooled by methane, a line 205, an exchanger 143, Fig. 2, cooled by ethylene and a line 206 leading to a surge tank 207 where liquid methane collects and from which it is withdrawn through a line 208 and expanded at a valve 211 into flash zone 212. Methane gas withdrawn from 212 is returned through heat exchangers 213 and 204 to the third stage 216 of compressor 200, whilst the liquid methane withdrawn from zone 212 and not returned thereto through exchanger 217 is expanded at a valve 221 into a second flash zone 222. Flash gas from 222 is returned through exchangers 223, 213, 204 to the second stage 226 whilst a portion of liquid methane is thermosyphoned to zone 222 through a heat exchanger 227, thereby cooling feed gas in line 10, whilst the remaining liquid methane is expanded at a valve 231 into a third flash zone 232 from which methane gas is returned through a line 234 and exchangers 233, 223, 213, 204 to the first stage 236 of compressor 200, thus completing the refrigerant methane cycle. Liquid methane withdrawn from zone 232 is thermo-syphoned back through a heat exchanger 237 which effects liquefaction of the feed gas in line 10. Preliminary cooling of feed gas in line 10 is effected using a closed propane refrigerant cycle comprising a two-stage compressor 12 and flash zones 19, 27 associated with exchangers 11, 29, through which liquid propane is thermosyphoned back to the flash zones. Further cooling of feed gas leaving exchanger 29 is effected by a closed ethylene refrigerant cycle comprising a three-stage compressor 110 and flash zones 112, 122, 132 associated with exchangers 117, 127, 137 through which liquid ethylene is thermo-syphoned back to the flash zones. The propane cycle also includes flash zones 48, 62 and exchangers 49, 63 which cool ethylene and includes a flash zone 41 and exchanger 42 which cools refrigerant methane. Similarly the ethylene cycle includes a flash zone 142 and exchanger 143 which cools refrigerant methane.

Title: Time lapse circuit for a time lapse relay
IPC: H03K17/292
Filed: 1978-04-18
Abstract: The charging process of a capacitor (C1) of a series RC circuit (R1, C1) is monitored by means of a four-layer diode (T1) which compares the charging voltage rising across the said capacitor (C1) with a reference voltage picked up at a low-resistance voltage divider (R2, R3). When the charging voltage reaches the sum of the reference voltage and the firing voltage of the four-layer diode, the latter becomes conductive. When this is the case, the said capacitor (C1) is discharged via the four-layer diode, a further resistor (R4) and a part of one of the resistors (R3) of the voltage divider. The discharge current surge due to the further resistor generates in the latter a voltage drop which can be picked up at a terminal (Kl 3) and is used as control signal for a timing relay. <IMAGE>

Abstract: 543,870. Lifting dogs. UNITED STEEL COS., Ltd., and COY, E. R. Oct. 17, 1940, Nos. 15369/40 and 12340/41. [Class 78 (iv)] Lifting dogs of the type shown, in which a pair of opposed pivoted jaws 1 with upward extensions 1a, 1b are adapted to grip and lift the load, are provided with a latch lever 5 with latch bye-passing means to prevent closure of the jaws when unloaded while allowing them to close for gripping the load, these operations taking place automatically when the apparatus is raised or lowered. The latch lever 5 is pivoted to one arm 1b and a recess 5a at its other end co-operates with a pin 7 on arm 1a to prevent closure of the jaws when unloaded. The pin is, however, disengaged from the recess 5a by a latch bye-passing means consisting of a lever 6 pivoted to one side of lever 5 and counter-weighted so that the end which covers the recess 5a tends to rise. The end of lever 6 is flanged laterally at 6a to form a partial closure for the recess. When the apparatus is lowered on to the load, the jaws and the arms 1a, 1b separate and pin 7 moves to the right out of recess 5a, lever 6 tilting slightly to allow this movement but returning as soon as pin 7 has passed. When the apparatus is raised, the jaws close to grip the work and pin 7 first slides along the outer surface of the projection 6a and then bears against the underside of lever 5 which it supports. When the load is lowered to rest on the ground, the jaws open, pin 7 moves into recess 5a and prevents closure of the jaws when the apparatus is raised away from the load. In a modification, the shape of the recess is modified and an additional or transfer lever is provided to prevent pin 7 from passing outwardly from the recess when the load is released.

Abstract: 1433652 Fluidic control circuits LEESONA CORP 8 April 1974 [9 April 1973] 15532/74 Heading F1P The circuit shown in Fig. 2 moves a piston 21 through one reciprocation cycle from the position shown when a start lever 23 is operated. This causes fluid from a source 26 to be momentarily vented through a restrictor 30 and a vent 33. A bi-stable device 36 is depressurized and changes over, so that a chamber 46 also becomes depressurized through chambers 37, 38 and vent 40, thus bi-stable device 47 changes over. This allows fluid from source 60 to pass through chamber 64 to begin to move the piston 21 to the right. At the end of the stroke a detent 68 opens a vent 80 and causes the bi-stable element 85 to reverse the element 47 by opening a vent 87. The element 47 reverses the fluid supply to the piston, fluid being supplied from the source 60 through a chamber 61 to extend the ram. Venting from the opposite side of the piston occurs through a chamber 62 and a vent 63. When the vent 80 closes as the detent 68 moves away, vent 87 is closed so that element 47 can be reversed by element 36 when required. By linking the detent 68 to the start lever 23 the cycling may be made continuous. Digital signals from points A-H may be displayed, Fig. 4, (not shown) and used to diagnose faults in the system. Specification 1433651 is referred to.

Title: Improvement in pest control composition
Filed: 1948-06-11
Abstract: Stabilized rosin amines are prepared by reacting stabilized rosins, i.e. rosin acids containing less than two ethylenic double bonds such as dehydroabietic acid, dihydroabietic acid, tetrahydroabietic acid or polyabietic acids, with ammonia to form a nitrile and then hydrogenating the nitrile to form the amine.  The nitrile may be prepared by passing gaseous ammonia into the molten rosin material whilst simultaneously vaporizing the resulting water; or heating the rosin material with ammonia in the presence of a dehydration catalyst, the nitrile being subsequently purified by neutralization or distillation.  The hydrogenation of the nitrile to the amine may be carried out in the presence or absence of ammonia or a solvent at pressures of 200 to 8000 pounds per square inch and temperatures of 20-200 DEG  C. Suitable catalysts for this reaction are nickel, cobalt, Raney nickel or cobalt, platinum, palladium, palladium on carbon, or reduced platinum oxide.  The resulting primary rosin amines may be converted to secondary or tertiary rosin amines by treatment with an alkyl halide or sulphate, or simultaneous condensation and reduction of the rosin amine and an aldehyde or ketone.  Secondary and tertiary alkanol amines may be prepared by reacting the rosin amines with ethylene oxide or other epoxide.  The tertiary rosin amines may be converted into quaternary ammonium compounds by addition of alkyl, alkenyl or aralkyl halides, or dialkyl sulphate, or by the reaction of a halohydrin, such as ethylenebromohydrin.  All the amines may be converted into salts.  An extensive list of such amines and their salts is furnished.  The amines may also be reacted with salts of copper, zinc, chromium, mercury, silver, aluminium, iron, cobalt and nickel to form complex metal amine salts.
