Patent GB-742812-A (GB)
Title: Process for impregnating fibrous material with micro-biocidal substances
Filed: 1953-05-06
Abstract: Solutions or dispersions of organic microbiocidal mercury compounds of formula R-Hg-X, where R is a mono-nuclear aromatic residue and X is an anionic radical and of basic organic polymeric nitrogen-containing condensation products or their water-soluble salts ("fixing components"), the condensation products being soluble in an aqueous medium and adapted to form complexes with the chemically bound mercury are used to impregnate fibrous material. Specified microbiocidal compounds include phenyl-mercury-lactate, hydroxide, acetate, formate and borate, m-tolyl mercury acetate, p-amino-phenyl-mercury-acetate, lactate and sulphate, p-dimethyl-amino - phenyl - mercury lactate, p - hydroxy - phenyl-mercury chloride and p-diethylamino-phenyl mercury lactate, chloride and acetate.  Fixing components specified include higher molecular poly-alkylene-polyamines obtained by reacting alkyl halides such as ethylene dichloride, propylene dichloride, glycerin dichlorhydrin and epichlorhydrin with ammonia, ethylene diamine, propylene diamine or other polyamines as such or as their alkylated or peralkylated products.  Condensation products obtained from polyalkylene-polyamines such as diethylene triamine, triethylene tetramine and tetraethylene pentamine and compounds containing the grouping <FORM:0742812/IV(a)/1> such as dicyandiamide, guanidine, biguanide, guanylurea and amino-guanidine may be used, as also may the condensation products obtained from compounds containing the <FORM:0742812/IV(a)/2> grouping and formaldehyde and ammonium and amine salts.  The two treatments may take place simultaneously or the solution of the mercury-containing compound may be used for impregnation prior to or after the impregnation with the fixing component.  It is preferred to mix the two materials and dissolve the mixture in the required amount of water.  The solutions may contain in addition hydrophobic compounds, solubilizing agents, stabilizers, surface-active compounds or compounds to maintain a definite pH. In an example a condensation product obtained by reacting glycerine-dichlorhydrin with ammonia and treating the product with dicyandiamide or cyanamide and formaldehyde is mixed with phenyl-mercury-acetate and dissolved in water is used to impregnate cotton fabric.

Title: Process for extracting the non-saponifiable and the difficult saponifiable matter from fatty material
IPC: A61K31/16
Filed: 1928-04-30
Abstract: 289,798. Marcus, J. K. April 30, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 1, 1928J. Soaps, processes and compositions for making. -Vitamines " A," " D," and " E " are separated with the non-saponifiable and difficultly saponifiable matter from fish, vegetable, or animal fats or tissue, by saponifying, and extracting with ethylene di-chloride. Light and oxygen should be excluded. In an example codliver oil is saponified with an excess of 10-15 per cent of potash in aqueous alcohol, the proportions then adjusted to produce a viscous soap mass containing about 60 grams of 30 per cent aqueous alcohol to each 100 grams of oil saponified, and the mass repeatedly extracted with ethylene dichloride. The extract is dried by sodium sulphate or other desiccant, filtered, and freed from solvent in vacuo. The vitamine concentrated may be preserved by dissolving in medicinal mineral oil, and may be administered in this form. The soap to be extracted may be obtained by saponifying the oil with excess of alcoholic potash, distilling off excess alcohol and adding the necessary water, or by using insufficient alcohol to dissolve the reaction mixture, e.g. 50 per cent alcohol amounting to 40 per cent of the oil treated, and adding water after saponincation. According to the Specification as open to inspection under Sect. 91 (3) (a) extraction is effected by " an organic chloride." This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to time indicating devices
IPC: G04F7/06
Filed: 1944-07-04
Abstract: 594,291. Clocks. STEVENS, A. H. (Bausch & Lomb Optical Co.). July 4, 1944, No. 12740. [Class 139] A device for giving a factor for use in determining the average civil time of two preselected events comprises means for indicating one half the time between said events as it elapses. The invention is in the form of a navigator's watch the operating mechanism of which comprises a driving pinion 17 (spring drive not shown) which can selectively drive either one of a pair of pinions 40, 41 carried by spindles 42, 51 mounted in a cage 34. The pinions 40, 41 are connected through gearing to minutes and seconds hands which move over an ordinary watch dial the number of teeth of pinions 40, 41 being such that when pinion 17 is driving pinion 41 the hands are rotated at normal clock speed and if pinion 17 is driving pinion 40 the hands are rotated at half the normal speed. Normally the pinion 17 is driving the pinion 41; pressure on knob 22, however, moves a lever 21, an arm 23 and so turns a ratchet wheel 25 which carries with it a turret wheel 29 which by means of a pawl and arm arrangement 30, 31 rocks the cage 34 to bring the pinion 40 into mesh with the pinion 17, whereupon the hands will be rotated at half normal speed. A second pressure on the knob 22 causes the brake surface 55 of a bellcrank lever 53 to engage the balance wheel 15 so stopping the clock movement. The hands will then indicate the average time at which the first and second pressures of knob 22 were made, the pressures coinciding in this case with two celestial observations of the navigator. A third depression of the knob 22 will cause the pinion 17 to drive the pinion 41 again to rotate the hands at normal speed.

Filed: 1919-05-22
Abstract: 166,224. Antranikian, H. May 22, 1919. High-frequency machines; inductor-alternators.-In a high-frequency alternator having a toothed stator and rotor in two parts energized by a circular coil between the two parts, the width of the teeth of the stator or armature is made equal to D/2 + K V/2f where D is the pitch of the teeth, V is the speed of the rot r, f the frequency of the current, and K a whole member. The width of the inductor teeth is made less than the width of the armature teeth, the widths being in the ratio of an odd number to an even number. The width e, Fig. 1, of the inductor teeth is expressed by the formula e = (Cz + 1)V/f, z being any whole number and C being equal to 1 or 2. The machine may be constructed so that the two stator parts and the two rotor parts may be displaced relatively to each other by an amount equal to V/2f so as to reduce the frequency to half its 2f normal value.

Title: Improvements in and relating to echo-ranging and the like
Inventor: HOPKIN PETER ROY
IPC: G01S7/62
Filed: 1958-04-23
Abstract: 868,146. Echo sounding; distance measuring apparatus. KELVIN & HUGHES Ltd. April 21, 1959 [April 23, 1958], No. 12966/58. Class 40(7). An apparatus used for ranging, as for example in radar, echo-sounding, or flaw detection systems, and in which only echo signals received from within a particular range are displayed, the time base of the display being triggered by an echo from the further limit of said range, comprises a recording medium moved recurrently relative to a record/reproduce head and an erase head, and includes means for switching the former head between its two conditions and for switching off the erase head during reproduction. As described with reference to fish detection the apparatus includes a rotating magnetic recording drum 19, a record/reproduce head 16 and an erase head 18. The transceiver unit 10 transmits pulses (a) which return as (b) in the form of transmitter break-through pulses 11, fish echoes 13 and bottom echoes 12. The break-through pulses are muted and signals (c) pass to the recording drum via units 14, 15 and 16. The bottom echo 12 is passed (d) by an amplitude gate 20 to trigger multivibrator 22. This gives a long negative pulse (e) whose negative going edge changes switch 15 to its reproduce condition and also switches off the erase and bias oscillator 17. The recording drum makes several revolutions during the negative pulse (e) and hence the reproduced signal is as at (f). This signal is fed to the display 29 and to an amplitude gate 31 which passes the bottom echoes (g). These trigger a second multivibrator 33 which in effect delays each reproduced bottom echo by a time t<SP>1</SP>, (h), the delayed pulses being used to trigger the display time-base 30 sweep waveform (i). In this manner the blank periods corresponding to the erased portion of the drum 19, which lies between heads 16 and 18, are not displayed. Repeated display of the recorded signals occurs until the positive going edge (e) returns switch 15 to the record condition and switches on oscillator 17 prior to the reception of the next bottom echo. Specifications 785,001 and 839,131 are referred to.

Patent GB-403071-A (GB)
Title: Improvements in processes for the saponification of organic esters of cellulose
IPC: D06M11/38
Filed: 1932-05-06
Abstract: By conducting the saponification of filaments, threads, yarns, &c. of cellulose acetate and other organic esters of cellulose on the materials while travelling at a speed which diminishes along their path so that contraction may take place, an improvement in tensile strength results.  Preferably washing and drying are also so conducted as to allow the materials to contract.  When saponification is carried out in a bath the speeds of the feed and delivery rollers are suitably adjusted, and the tension to which the threads are subjected may also be controlled by causing the saponification liquid to flow in the direction the threads are moving; if the saponification liquid is applied by padding &c., then the speeds of the drying drums, during passage over which saponification actually occurs, as described in Specifications 316,521 and 318,468, [both in Class 2 (ii), Cellulose &c.], are adjusted in an appropriate manner, and in this case by making the surfaces of the drums very smooth contraction may be assisted by the slip that naturally takes place. Saponification may be effected by aqueous solution of alkali, or by alcoholic solutions as in Specification 125,153, [Class 2 (ii), Cellulose &c.], or solutions in glycols, glycerol &c. as in Specification 313,404, [Class 2 (ii), Cellulose &c.], or with the addition of lime as in Specification 402,106, and buffer salts may be added to saponifying bath, which may also contain oils and fats as described in Specifications 400,996; and the saponifying agent may be applied as a spray or in the form of vapour.  The extent of the saponification may vary according to the effect desired from a loss of weight of 2 per cent to complete elimination of the ester groups. The cellulose acetate &c. constituting the basis of the threads &c. may be of low, medium or high viscosity.  Contraction of the saponified materials may also take place on the bobbin, beam or other package on which the yarn &c. is wound, the yarn being slackly wound thereon, preferably with cross-winding. Before saponification, the materials may be subjected to a stretching operation, as described in Specifications 277,089, 323,790, [both in Class 2 (ii), Cellulose &c.], 370,430 and 371,461, or the stretching may take place during the manufacture of the threads as described in Specifications 340,324,340,325,340,326,340,436, 340,437, 343,062, and 378,858. The materials may be subjected to a shrinking operation subsequent to saponification, but preferably between stretching and saponification, and the shrinking may be carried out as in Specifications 380,504, 380,505, and 389,823.  Specifications 330,950, 332,263, [both in Class 2 (ii), Cellulose &c.], and 351,417 also are referred to.

Abstract: 783,422. Injection-moulding machines. PUCKERT, E. W. May 6,1955 [May 6, 1954], No. 13283/54. Class 87(2). Two co-operating mould parts M, M<SP>1</SP>, Fig. 1, are carried by plates 17, 17<SP>1</SP> pivotally connected to arms 19, 19<SP>1</SP> pivoted on fixed crossheads 21. Fig. 1 shows the mould-closed position and Fig. 2 the mould-open position in which the arms 19, 19<SP>1</SP> have pivoted counterclockwise and clockwise respectively. The mould parts are held in the closed position of Fig. 1 by the pressure of the injection ram 15, the ram acting through the material in the injection cylinder 14. The machine comprises two uprights 2, 5 joined by rods 6, 7 on which slide a pair of crossheads 20 and two crossheads 29, 28. Crossheads 20 control the movements of the mould parts, being provided for this purpose with vertical grooves 23 in which slide lugs 22 on plates 17, 171. Crosshead 29 carries the injection cylinder 14, which in turn carries the feed hopper 13. Between crossheads 20 and 29 are disposed springs 30 which surround rods 7. Other springs 25 surrounding rods 6 are disposed between a fixed crosshead 1 and crossheads 20. The mould is held in the open position shown in Fig. 2 by rods 31 threaded into crossheads 20 and secured to crosshead 28 which is fixed to ram 15. Operation. The mould being open, as in Fig. 2, the operator admits fluid pressure to cylinder 9 to move crosshead 28 to the left, whereupon the springs 25 move heads 20 to the left to pivot arms 19, 19<SP>1</SP> from the Fig. 2 position to the Fig. 1 position and thus close the mould. Continued movement of piston 15 compresses material in cylinder 14 and moves the forward end 24 of the cylinder against the mould, thus locking it in position. After injection, piston 15 retracts, compression springs 30 return the injection cylinder to the Fig. 2 position (where it is held by the abutment of a pin 38 thereon with crosshead 1) and the rods 31 pull the mould open against the action of the springs 25. As the mould opens a stud 35 acts on an ejector pin 34 to discharge the moulded article.
