Title: Safety device for automotive vehicle
IPC: F02D17/04
Filed: 1973-06-11
Abstract: 1418232 Transistor delay circuits L GUILLAUME 11 June 1973 [15 June 1972] 27629/73 Heading H3T [Also in Division F1] In an arrangement for disabling a vehicle ignition system in the event of a monitored physical parameter reaching a threshold value, operation of the disabling circuit is delayed for a predetermined time after the threshold is reached. A further delay is also provided to inhibit the disabling circuit when starting the vehicle. Under normal conditions, capacitor 5 is charged via diode 9 to hold transistor 7 conducting. In the event of an abnormal condition reaching the threshold, one of the switches 1 closes earthing point A and sounding alarm 11. Diode 9 is now reverse biased and capacitor 5 discharges through resistor 6 until transistor 7 cuts off, turning on transistor 8 to fire SCR 3 and disable the ignition. If one of the monitored conditions is oil pressure, operation of the disabling circuit during starting is prevented by a circuit 12. Operation of the starter applies a positive voltage to terminal 13 which hold transistor 7 conducting long enough for the oil pressure to build up to normal.

Title: Processes for producing ª‡, ª‰-unsaturated aldehydes and esters of ª‡, ª‰-unsaturated acids
IPC: C07C51/285
Filed: 1962-07-18
Abstract: Esters of a ,b -unsaturated carboxylic acids are prepared by oxidizing an olefine with an oxygen-containing gas to the corresponding a ,b -unsaturated aldehyde in the presence of a catalyst comprising 100 parts by weight of molybdenum trioxide, 1-100 parts of phosphorus pentoxide and up to 100 parts by weight of vanadium pentoxide, dissolving the a ,b -unsaturated aldehyde in methanol or ethanol, and oxidizing the alcoholic solution with hydrogen peroxide as oxidizing agent in the presence of a selenium dioxide catalyst.  Propylene, isobutylene and b -butylene are specified to yield acrolein, methacrolein, and crotonaldehyde, and methacrylate, methyl methacrylate and methyl crotonate, respectively. The catalyst is supported on a carrier such as aluminium sponge, fused alumina, coal cinders, pumice, activated alumina, silicon carbide, silica gel and fire stone, and may include oxides of arsenic, boron, titanium, tungsten, copper, silver and nickel as promoters.  Air or oxygen mixed with nitrogen or carbon dioxide may be used as the oxidizing gas.  A process for the separation of the aldehyde from the by-products is also described.  By-product unsaturated acids from the oxidation stage may be esterified in the presence of a catalyst such as concentrated sulphuric acid.ALSO:A catalyst composition comprising 100 parts by weight of molybdenum trioxide, from 1-100 parts by weight of phosphorus pentoxide, and up to 100 parts by weight of vanadium pentoxide is used in the oxidation of an olefine by an oxygen-containing gas to the corresponding a ,b -unsaturated aldehyde.  The catalyst may be supported on a carrier such as aluminium sponge, fused and activated alumina, coal cinders, silicon carbide, silica gel and firestone and promoters such as the oxides of arsenic, boron, titanium, tungsten, copper, silver and nickel may be included. The preparation of the catalyst may be by impregnating fine granules of carrier e.g. aluminium sponge with a warm aqueous mixture of molybdate and vanadate, and phosphoric acid made alkaline with ammonia, and evaporating the mixture to dryness. The dried mass is heat treated at from 300-450  DEG C. in a mixed gas atmosphere.

Title: Improvements in stop mechanisms
Inventor: MACKIE JOHN PRINGLE
IPC: D03D51/00
Filed: 1955-09-29
Abstract: 842,972. Stop mechanism for textile machines. MACKIE & SONS Ltd., J. Oct. 1, 1956 [Sept. 29, 1955], No. 27758/55. Addition to 732,549. Classes 120(2), 142(1) and 142(2). The stop mechanism of the parent Specification is modified in that the abutment yields when engaged by the detector or a part acting with it and in yielding operates a device for stopping the machine. Further the stop mechanism is adapted for the control of weft yarn in a shuttleless loom, for the control of yarns passing from the-creel to the beam of a beaming machine and for the control of yarns to be twisted in a twisting machine. The embodiment shown is for use in a shuttleless loom and consists of a detector 1 suspended from a pivot 2 at the end of an arm 3 caused. to rock about an axis 4. The detector 1 co-operates with the weft yarn 20 as it passes over support 21 which constitutes the abutment. The support 21 is pivoted at 22 and bears against the plunger 23 of switch 24. In normal operation as the detector 1 is moved into contact with the yarn it is swept aside by the yarn into the position shown in dotted lines at 1<SP>1</SP>. If the yarn is missing or running below speed, however, the detector is not swept aside and in consequence bears on the support 21 causing the latter to yield and rock about its pivot 22 to operate the switch 24 to stop the loom. Similar arrangements are shown for application to a beaming operation and to a twisting machine. In the latter the mechanism controls a mechanical latch which in turn controls a gripping device stopping the feed of the yarn.

Filed: 1929-09-16
Abstract: 339,968. Electrical Research Products, Inc., (Assignees of Gilbert, J. J.). March 23, 1929, [Convention date]. Drawings to Specification, Cables with artificially modified capacity; loaded cables.-In order to facilitate the transmission of voice frequency currents over long loaded submarine cables of the twin core type, the electrical properties of the core lengths are measured during manufacture, and the core lengths grouped so that the cores in any group have approximately identical initial inductance. Pairs are selected from each group having the same capacity and are twisted together. The twisted pairs are then arranged in the cable in order of decreasing hysteresis resistance, the pairs having the lowest hysteresis resistance being placed near the cable end, and those having the highest hysteresis resistance, in the centre of the cable. In the case of a twin core termination of a single core cable, the core lengths may be first grouped as regards hysteresis resistance, the lengths being then paired to obtain balance of inductance and capacity. The method of grouping may be applied to coil-loaded or intermittently loaded cables.

Abstract: 1413067 Cracking TEXACO DEVELOPMENT CORP 14 June 1973 28314/73 Heading C5E A paraffinic raffinate (4), e.g. from the solvent extraction (2) of a reformed naphtha, is divided into two streams of which one is hydrocracked (6) and the other catalytically cracked in a fluidized zone (8). Light naphthas of improved octane rating (12 and 21) are recovered from both. A stream (10) rich in isobutane is recovered from the hydrocracking, and a stream (19) rich in propene and butene from the catalytic cracking. These two streams are alkylated together (11), and the proportions of the raffinate in the two streams are adjusted to yield isobutane and olefines in the right proportions for the alkylation. If the raffinate contains heavier fractions, heavy naphthas will also be recovered from both cracking zones. These can be recycled (15 and 26) to their respective cracking zones, or can be reformed (14) to provide part of the feed to the solvent extraction. The rest of this feed is derived from an external supply (25). Gas oil may also be supplied (16 and 27) from an external source to the two cracking zones, and other fractions may be taken off as shown.

[Class 37] A spacer-electrolyte is made by applying to a paper sheet a liquid mixture formed by adding together a solution of a suitable cellulose ester or ether, one or more ionogens and one or more high-boiling point organic liquids which are not solvents for the cellulose ester or ether but dissolve or combine with the ionogen, and then drying the composition so as to allow liquid electrolyte to exude from the mixture into the paper as the solvent for the ester or ether evaporates. Cellulose esters or ethers are unsuitable if they produce corrosion of the electrodes like nitrocellulose or contain sulphates or chlorides soluble in the electrolyte, or are not precipitated by water or an aqueous solution of the ionogen. Cellulose acetate, ethyl cellulose and cellulose aceto-butyrate are preferred. Examples of solvents are acetone, methyl acetate, ethyl formate or ethylene glycol diacetate.
