Title: Improvements relating to the fixation of dyestuffs on textile fibres
IPC: F16L27/10
Filed: 1933-12-22
Abstract: Acid or substantive dyes, dyeing with; regenerated celluloses, dyeing.--To improve the fastness to washing of dyeings normally loose to washing, and to make possible the production of dyeings with dyestuffs having little or no affinity for the fibres, upon regenerated cellulose fibres, vegetable fibres such as cotton or upon natural silk, the fibres are impregnated or dyed with acid or direct dyestuffs, impregnated simultaneously or subsequently with an aqueous solution of materials capable of yielding in acid medium a synthetic resin of the urea-, thiourea-or dicyandiamide-formaldehyde type and dried and the resin is subsequently insolubilized by heating to 180--210 DEG  C. for 30--60 seconds.  The formaldehyde is preferably employed in excess of the amount required for the formation of dimethylolurea or analogous dimethylol compound.  The application of the formaldehyde to the fibres may follow that of the dyestuff and of the amidic component.  The following examples are specified.  (1) A cuprammonium artificial silk fabric, dyed with Chlorazol fast scarlet 4BS, is impregnated with an aqueous solution containing urea and ammonium acetate with an addition of formaldehyde followed by standing for 30 minutes, and the impregnated fabric is dried and heated for 30 seconds at 200 DEG  C.  (2) A viscose artificial silk fabric, dyed with Diamine rose FFB, is impregnated with an aqueous solution containing acetic acid, formaldehyde and a mildly alkaline solution in which dicyandiamide and formaldehyde have reacted for 15 minutes at 50--60 DEG  C. and the impregnated fabric is dried and heated for 30 seconds at 200--205 DEG  C.  (3) A fabric having a cotton warp and a viscose artificial silk weft is impregnated with an aqueous solution containing Chlorazol fast red K, acetic acid and a solution in which urea and formaldehyde have reacted for 15 minutes at 30--35 DEG  C. under mildly alkaline conditions followed by neutralization, and the impregnated fabric is dried and heated for 50 seconds at 200 DEG  C.  (4) A cotton fabric is impregnated with an aqueous solution containing Lissamine violet 2R, acetic acid and the urea-formaldehyde condensate in (3) and the impregnated fabric is dried and heated for 50 seconds at 200--205 DEG  C.  (5) A natural silk fabric, dyed with Lissamine red 6B' is impregnated with a solution of urea-formaldehyde condensate as in (1), dried and heated for 30 seconds at 200 DEG  C.  (6) A cotton fabric is impregnated with an aqueous solution containing urea, ammonium acetate and Chlorazol fast red K, the impregnated fabric is dried, treated for 15 minutes in an atmosphere of steam containing formaldehyde in excess and heated for 30 seconds at 200 DEG  C.  The Provisional Specification refers to the use of ammonium salicylate and ammonium glycollate in place of ammonium acetate in urea-formaldehyde mixtures.  Reference has been directed by the Comptroller to Specifications 328,978, [Class 15 (ii)], and 424,535.

Title: Process for the preservation of fats
IPC: A23L3/358
Filed: 1928-12-11
Abstract: 303,059. Deurs, J. A. S. van. Dec. 27, 1927, [Convention date]. Preserving fat.-The fatty content of animal and vegetable substances is preserved by giving the tissues surrounding the fat a P H value of less than 5, e.g. by adding an agent which can in aqueous solution augment the hydrogen ion concentration by liberation of hydrogen ions or by hydrolysis, or by adding acid producing microorganisms. This PH value is not deliberately altered during the preservation period. The substances which may be treated include cod and other fish livers, fish such as herrings, fruits such as palm fruits, and copra and like seeds. Examples are given of the treatment of cod livers and of olives employing hydrochloric acid as acidifying medium. Where the alteration of the hydrogen ion concentration is effected by acidproducing micro-organisms, lactic acid bacteria such as betacoccus bovis, betabacterium longum, and streptobacterium plantanum may be used.

Title: Improvements relating to Frequency Modulation Receivers for Data Transmission.
Inventor: LEWIS ALAN
IPC: H04L5/06
Filed: 1966-08-17
Abstract: 1,189,657. Digital transmission systems. EVERSHED & VIGNOLES Ltd. 14 Aug., 1967 [17 Aug., 1966], No. 36893/66. Heading H4P. A frequency shift receiver comprises means for counting clock pulses during a portion of a cycle of the received signal, the count representing the length of the cycle and hence the frequency. In the embodiment described, the received sine wave signal is squared up by trigger 16 and passed as P 1  to gate 18. The gate is fed by clock pulses and its output passes to counter 28. The trigger output also feeds a unit 22 which develops a signal P 2  which inhibits gate 18 from the start of each cycle of the received frequency shift signal for a time less than half a cycle of P 1 . At the end of this inhibit period the counter counts clock pulses. The count at a subsequent point in the cycle, determined by the delayed (42) output P 1  of trigger 16, is read out by enabling gates 30, 32, 34. Depending on the count, one of these gates triggers its associated bi-stable 36, 38, 40, to indicate a Mark, centre, or Space, frequency. Output P 1  resets the counter to zero in preparation for the next cycle. If the number of pulses exceeds the capacity of the counter, gate 18 is inhibited; there is thus no response to excessively low frequencies. There is also no response to excessively high frequencies since unit 22 inhibits gate 18 long enough that it passes no pulses in this instance.

Abstract: 1338507 Flash lamp circuits HUGHES AIRCRAFT CO 10 Aug 1971 [12 Aug 1970] 37534/71 Heading H2H [Also in Divisions H1 and H3] A switching circuit, suitable for use in a capacitor discharge lamp flasher for a laser comprises a switching transistor Q1 having regenerative feedback via a transformer T2 and a transistor Q2 substantially as shown. When a driver signal is applied to the base of Q2, Q1 is rapidly switched to saturation by regenerative feedback. Current builds up in the collector of Q1 until a limit is reached or the driver signal terminates. When this latter occurs the transistors switch off and this occurs rapidly as the drive current to the base while T2 is saturated is low. During switch off a pulse is produced across the secondary of a transformer T1 and this charges a pulse forming network 10 such as a capacitor. Alternate similar switching circuits 11 and 12 are used for the charging. In response to a trigger pulse from 16 the network is discharged into a lamp to pump a laser.
