Title: Artificial resinous products
IPC: C08G63/48
Filed: 1930-11-04
Abstract: Ester condensation products.--A polyhydric alcohol-polycarboxylic acid condensation product containing free hydroxy groups equivalent to at least one-third of those originally present in the polyhydric alcohol is made by treating a polycarboxylic acid with an excess of polyhydric alcohol or by treating a mutually satisfied polyhydric alcohol-polycarboxylic acid condensation product with a polyhydric alcohol with or without the addition of known alcoholysis catalysts. The product or the initial materials of the first stage is then heated with a fatty oil until the mixture is substantially homogeneous and this product is then treated with a polycarboxylic acid or a mixture of poly- and mono-carboxylic acids to esterify the free alcoholic groups.  Suitable polyhydric alcohols are ethylene glycol, mannitol, glycerol or mixtures of polyhydric alcohols and suitable carboxylic acids, which may be used as anhydrides, are succinic acid, phthalic acid, and citric acid.  Coconut oil, olive oil, linseed oil, and menhaden oil are suitable oils but hydroxylated oils such as castor oil are excluded.  Alcoholysis catalysts specified are calcium glycerate, acid calcium phthalate or sodium naphthionate.  In the final stage monobasic acids such as the higher fatty acids such as the fatty acids of fatty oils, aromatic acids such as benzoic acid or cinnamic acid and abietic acid or colophony may be used and if an excess of acid is used an amount of alcohol may be added.  In examples (1) glycerol and phthalic anhydride are heated together and linseed oil incorporated with the product.  Phthalic anhydride is added and the mixture heated to complete the condensation.  (2) Glycerol phthalic anhydride, linseed oil, and tung oil are heated together and the clear homogeneous product is heated with phthalic anhydride.  (3) Glycerol, phthalic anhydride, and linseed oil are heated together and the product is heated with glycerol and phthalic anhydride. (4) A glyceryl phthalate condensation product is heated with glycerol and then with linseed oil to give a product which is condensed with phthalic anhydride. (5) A glyceryl phthalate p  condensation product is pulverized and heated with glycerol, linseed oil, and calcium glycerate until the mixture becomes homogeneous and then phthalic anhydride is added. The product is soluble in solvent naphtha.

Title: Ignition circuit for an automatic telephone exchange containing cold-cathode tubes
IPC: H04Q3/52
Filed: 1958-10-17
Abstract: 884,375. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. (Philips' Gloeilampenfabrieken N.V.). Oct. 17, 1958, No. 33218/58. Class 40 (4). [Also in Group XIX] In a telephone system in which speech paths include cold-cathode discharge tubes which are fired to select a particular wanted path under control of a register marker, all the tubes are primed for firing only after the register has received a full set of digits. A two-digit register marker is shown in Fig. 1, digit trains being applied to a terminal 2 connected to all the trigger electrodes of tubes A1 to A10 of a decade counter. When a tube A fires it primes the next and extinguishes the preceding tube. Probe electrodes of the tubes A are connected over resistors R7 to trigger electrodes of a register comprised by tubes B 1 to B10. During the first pulse train as each A tube fires insufficient voltage builds up over resistors R6 and capacitors C3 to fire a B tube, but at the end of the train the last A tube is fired long enough to fire its associated B tube. When the B tube fires it locks out all other B tubes and pulses a self-extinguishing tube E which in firing extinguishes the fired A tube. The second and last digit is now received and the last fired A tube stays ignited to register the digit. Each combination of an A and a B tube are connected over resistors R18, R19, to a tube F in a speech path as shown in Fig. 2 where the blocks 10 and 11 indicate the counter tubes A and the register tubes B. The trigger electrodes of all the speech tubes F are multipled over voltage dependant resistors R20 to a point P at earth potential to lock the tubes out until a tube Y fires. A tube X fires in response to each pulse of the digit trains applied to the counter 10, but is self-extinguishing and during a pulse does not develop sufficient voltage in its RC anode circuit to fire the tube Y. At the end of the first digit X does generate sufficient anode voltage but the self-extinguishing tube E in clearing the counter 10 is also applied over R27 to hold Y cut off. At the end of the second digit train, however, X operates Y and markings extend from the counter and register to the tube F which is consequently fired as conduction through Y raises the potential of multipled point P. Striking of Y fires a tube Z after a delay and Z, which is self-extinguishing, triggers the tube E in clearing the register 11 over capacitor C15 while E clears the counter 10 and extinguishes the tube Y. The circuit is now normal except that a tube F has been fired.

Title: Improved means for actuating a vehicle hand brake
Inventor: BONNER DAVID GORDON
IPC: B60T7/10
Filed: 1953-12-01
Abstract: 742,635. Vehicle hand brake mechanism. GIRLING, Ltd. Nov. 30, 1954 [Dec. 1, 1953], No. 33313/53. Class 103 (1). In a vehicle hand brake of the type which comprises a rod 10, provided with a handle 11 on its outer end, mounted for axial sliding movement in a bracket 15 mounted on the dashboard 17 or other convenient part of the vehicle and adapted for connection at its inner end to a cable or other transmission member leading to the brake, a spring-pressed pivotally-mounted pawl 26 is provided to co-operate with notches 16 in the rod 10 to retain the rod in the brake applied position; the brake being released by turning the rod angularly to free the pawl 26 and bring the smooth portion of the rod into alignment with the pawl so that the rod is free to return to its normal " off " position, as shown in Fig. 1. The pawl 26 is pivotally mounted on a transverse pin 27, the axis of which is at right angles to the rod 10, in a sleeve 19 in which the rod 10 is slidably guided and which is retained in the bracket 15 by a resilient sheet-metal plate 20. To apply the brake, the handle 11 is pulled outwards from the "off " position shown in Fig. 1 so that the rod 10 moves outwards and the pawl 26 rides over the successive notches 16 in the rod such that when the handle is released the rod is moved inwardly through a small distance by the tension in the transmission line until the pawl has engaged a notch and rocks over to the position shown in Fig. 2. The rod cannot then be released accidentally solely by angular movement of the handle since the sleeve 19 moves with it and the pawl remains in engagement with the associated notch. To release the brake the rod must first be drawn outwards a short distance in the brake-applying direction allowing the notches 22 and 23 in the sleeve 19 to engage lugs 24 and 25 respectively in the housing and so key the sleeve against angular movement. At the same time the pawl is rocked over into an inclined position and the rod can be moved angularly relative to the sleeve to carry the notches 16 out of engagement with the pawl, as shown in Fig. 3, so that on release of the handle, the rod will return to its normal release position as illustrated in Fig. 1.

In the printing- telegraph apparatus shown in the Figure, a paper roll 5 rests on rollers 9 in yokes 8 on the platen-carriage 77, the paper web being led over guides 10, 11, around the platen 7, and beneath a knife 34. A bracket 14 secured to the yokes is provided with stub shafts 15 supporting a carbon-supply spool 17 and a spring-urged pivoted frame 24 which is provided with stub shafts 25 supporting a carbonwinding spool 33. The right-hand stub shafts 15, 25 are provided with large and small pinions 18, 27 meshing with a pinion 23 mounted on an arm 22 on the bracket 8. The carbon web passes from the supply spool to the winding-spool and around the platen. At each line-spacing operation, the carbon web is drawn off the supply spool, and the winding- spool is rotated more quickly than the supply spool, and when the carbon web becomes taut, the frame 24 is rocked to separate the pinions 27, 23, excessively tight re-winding being thereby avoided. In an alternative construction, both pairs of stub-shafts 15, 27 are mounted on ball-bearings in the bracket 14 and the righthand stub shafts are provided with pulleys which are connected by a spring belt adapted to slip when the carbon web becomes taut. The pulley associated with the shaft 25 may be provided with a slipping clutch.

Title: Coking heavy petroleum oils
IPC: C10G9/32
Filed: 1954-11-18
Abstract: <PICT:0762831/III/1> In a process of converting a heavy hydrocarbon oil into volatile products and coke by contacting the oil in a coking zone with hot solid particles of non-catalytic material in a fluidized state, the oil to be converted is used to scrub hot flue gases whereby dust is removed from the gases and the oil is preheated.  Crude petroleum is distilled at atmospheric pressure and under vacuum to a obtain a residium which contains no material boiling below 800 DEG -1000 DEG F.  The residium is introduced into the conversion plant (see Fig.) through lines 1a and 1b.  The feed leaving line 1a is mixed in line 2 with oil which has been preheated by contact (in scrubber 9) with flue gases; and part of the mixture is pumped through line 4 to manifold 11 where it is injected at a plurality of points into coking vessel 14 which contains a dense bed of high-temperature (e.g. 950 DEG F.) coke particles maintained in a fluidized state by steam injected through lines 16.  The vapours formed by pyrolysis of the oil pass out from the top of vessel 14, and are submitted to fractionation.  Coke product is removed from vessel 14 via line 17.  The temperature of the coking bed is maintained by continuously withdrawing a portion of the bed from vessel 14, passing it to transfer line burner 20 where carbonaceous material is burned, by air admitted through line 19, from the particles whereby they are raised to a temperature of about 1200 DEG F., discharging the combustion gases and entrained particles into cyclone 22, and returning the reheated particles to the coking bed via line 23.  The flue gases are removed from the cyclone via line 8, and are quenched in scrubber 9 with oil supplied through lines 4 and 7.  The scrubbed gases, now at a temperature below 500 DEG F., are vented through line 10; and the preheated oil is withdrawn from the scrubber through line 2.  Gas oil, which may be separated from the volatile products from the coking vessel, is introduced through line 1c into reactor 24 which contains a fluidized bed of cracking catalyst; and the cracked vapours are removed via line 25. Contaminated catalyst is continuously withdrawn from reactor 24, and transferred to regenerator 28 where it is fluidized by air introduced through line 29.  Regenerated catalyst is withdrawn from the regenerator through line 27, while the flue gases pass out overhead. These flue gases are quenched in line 30 with feed oil introduced through lines 1b and 38.  The mixture flows into separator 31, from which cool flue gases are discharged through line 32 while the heated oil is withdrawn through line 33.  Part of this oil is recycled via cooler 37 to line 38, and the remainder is pumped through line 13 to coking vessel 14.  Specification 585,990 is referred to.
