Title: Automatic control for transmitter
Inventor: LAYBOURN IAN DOUGLAS
IPC: H03L5/00
Filed: 1969-07-31
Abstract: 1,239,878. Frequency changers; automatic volume control. PYE Ltd. 31 July, 1969, No. 38504/69. Headings H3T and H4R. In a transmitter, a frequency mixer using, for example F.E.T. F2 receives one input from a first oscillator (1, Fig. 1, not shown) through a variable gain circuit 5, and a second input from a second oscillator (8), the circuit 5 having its gain controlled by a rectified smoothed a.g.c. signal derived from the output stage 13. The output of the first oscillator may be modulated (at 2). The variable gain circuit 5 consists of a F.E.T. F1 whose source drain path impedance is controlled by the a.g.c. signal from rectifier D1 and smoothing circuit RV2, C3. A substantially contsant means level output signal is thus obtained, whose magnitude is adjustable at RV1, which with R2 and diode-connected transistors TR3, TR4 constitutes a voltage divider. These diodes afford temperature stability, and also protect transistor TR2 from excessive voltages which could arise from output mismatch with an aerial. The complete transmitter uses a crystal oscillator (1), a switchable crystal oscillator (8) for selecting different carrier frequencies, an amplifier (6), a band pass filter (11), and a wide-band driver amplifier (12). A thermal cut-out T.C. is provided.

Title: Aminoplastic textile resin finishing compositions
IPC: C08G12/42
Filed: 1958-11-11
Abstract: 891,969. Melamine-ethyleneurea-formaldehyde resins. AMERICAN CYANAMID CO. Nov. 11, 1958 [May 5, 1958], No. 36180/58. Class 2(5) [Also in Group IV(c)] An infinitely water soluble stable textilefinishing melamine-ethyleneurea-formaldehyde resin composition is prepared by reacting, at 30‹-80‹C. and a pH of 7-11, 1 mol. melamine with 8-20 mols. of formaldehyde as paraformaldehyde, in presence of at least 6 mols. of methanol until a clear solution is formed and reaction is complete. Sufficient methanol is added to bring the total to at least 10 mols., the pH is adjusted to below 4 and the mixture stirred at 15‹-60‹C. until solution is complete. The pH is then re-adjusted to 8-10, and 0À6-1À2 mols. of ethylene urea are added and reacted at 30‹-80‹C. until reaction is complete. If desired, 0À25-1 mol. of a monoalkyl ether of diethylene glycol in which the alkyl group has 1-4 carbon atoms, or of a monoalkyl ether of ethylene glycol in which the alkyl group has 1-3 carbon atoms, may be added to the reaction mixture before adjustment of the pH to below 4. It is stated that ethanol, propyl alcohols, butyl alcohols or mixtures of them may also be employed in place of methanol. The substantially fully methylolated and etherified melamine containing excess methanol and free formaldehyde is preferably vacuum concentrated before reaction of the ethylene urea with the free formaldehyde. The compositions are applied to textiles together with a curing catalyst, e.g. phosphoric, tartaric or oxalic acid, ammonium chloride, diethanolamine hydrochloride or magnesium chloride, and the material is then dried and heated to cure the resin. Any ordinary acid or alkali may be employed for the various adjustments of pH. Triethanolamine is particularly useful for the initial methylolation step. When sodium hydroxide is used in this step, particularly favourable results are obtained by adding nitric acid just before the etherification step. It is stated that the compositions of the present invention may be employed with urea-formaldehyde resins; 1,2- or 1,3-propylene urea-formaldehyde resins; guanamine-formaldehyde resins or their alkylated derivatives; homo-polymers of lower alkyl acrylates or their copolymers with styrene or substituted styrene; polyacrylonitrile or polyvinyl chloride. Other conventional treating bath components, e.g. softeners, stiffeners, lubricants, dicyandiamide may also be included. Specification 882,655 and U.S.A. Specifications 2,529,856, 2,690,404 and 2,804,402 are referred to.

Dec. 19, 1934, Nos. 36472/34, 793/35, and 35114/35. [Class 44] For the manufacture of any desired length of fastener of the type in which two stringer tapes each fitted with a series of interlocking elements are brought into engagement by a slider, a continuous length of stringer tape has a few elements removed at the intervals required to give the desired lengths, which lengths are then cut off and fitted with the end stops and the ends of the tape are treated to prevent fraying. A continuous length of two interlocked stringer tapes may be used which is cut off in the desired lengths by two guillotine knives properly staggered to enter between the respective sets of elements, while at the same time tools cut off the legs of the adjacent elements but without damaging the tape beadings. Fabric strips are now folded over the edges of the tapes at the two ends of the length and are cemented or sewn thereto. The bottom stop is fitted over the binding- strip at one end and the binding-strip at the other end is cut at the middle to allow the slider to be fitted. Finally the top stops are fitted, which preferably consist of slotted tubes embracing the severed edges of the top binding- strip. The tape ends may be impregnated with bonding-material such as rubber or celluloid solutions to prevent fraying or a rubber border may be moulded thereon and form the top stops as described in Specification 447,616. The operations of reinforcing the tapes at the required situations, removing the elements, fitting the stops, and cutting off the lengths may be carried out in different sequences.

Title: Arrangement for purifying crude benzene
IPC: C07C7/163
Filed: 1956-11-29
Abstract: <PICT:0844380/IV(b)/1> <PICT:0844380/IV(b)/2> In an arrangement for purifying crude benzene by catalytic pressure refining in the vapour phase with circulating hydrogen at elevated temperature and pressure wherein fresh hydrogen introduced to replace consumed hydrogen contains carbon monoxide, is saturated with steam and is introduced into the system in the reactor, the means for introducing the fresh hydrogen is so arranged that there is present in the reactor a zone wherein carbon monoxide and steam are catalytically converted to hydrogen and carbon dioxide prior to mixing with the circulating gas and the fresh hydrogen is heated by heat exchange with the circulating gas.  This may be accomplished as in Fig. 1 passing the circulating gases through line 4 down through the catalyst bed 2 and out through exit 5; fresh hydrogen is heated and introduced through duct 10 and spray nozzles 11 from which the gases emerge at such speed that the circulating gases are displaced and mixing does not take place instantly.  In an alternative arrangement Fig. 2, the fresh hydrogen introduced by duct 10 passes through empty space 16 where it may be heated and then through catalyst bed 15, the catalyst being the same as or different from that in bed 2. The fresh hydrogen may be mixed with the circulating gas before or at the end of the reactor.  Heat produced by the pressure refining is absorbed by the fresh hydrogen by heat exchange.  Refining conditions may be 320-350 DEG C. and 40-50 atm.  The fresh hydrogen may be town gas containing 14-15% by volume of carbon monoxide and is preheated 150-180 DEG C. and saturated with steam before passing to the reactor.  The amount of circulating gas required is about 1600 SCM per ton of crude benzene produced in a coke works and contains about 2% by volume of carbon monoxide.
