Patent GB-469020-A (GB)
Title: Improvements relating to the finishing or treating of cotton or mixed piece goods and to the manufacture of artificial yarn and filaments
IPC: D06M11/62
Filed: 1936-01-15
Abstract: Cotton or mixed piece goods are treated with a solution of the double salt of copper sulphate, one molecular proportion, ammonia, four molecular proportions, and caustic soda, two molecular proportions, with excess of ammonia.  The solution may also contain dissolved cellulose, or it may dissolve cellulose from the material under treatment.  When the solutions contain cellulose they may also be employed for the production of artificial filaments by dry or wet spinning methods.  In an example, 8 litres of ammonia, 26 DEG B<\>ae., are added to a solution of about 161 ounces of copper sulphate crystals dissolved in water.  The solution is cooled and iron precipitates are removed.  The solution is then mixed with ice and then with a solution of about 53 ounces of caustic soda in water also cooled by addition of ice. The solution of the double salt of copper sulphate, ammonia, and caustic soda may then be mixed with bleached cotton linters to form a cellulosic solution.  The double salt is formed in the presence of excess ammonia, the total proportion of which may be eight or more molecular proportions for each molecular proportion of copper sulphate.  Cloth may be led through the cellulosic solution and through squeezing rollers.  The solution may contain pigments, fillers, oil emulsions, or dyes.  The solution may be printed on the cloth.  The cloth may be dried by a current of warm air.  The copper may be removed by treatment with acid followed by washing.  Cloth may be treated with the solution of the double salt without addition of cellulose.  In this case cellulose may be dissolved from the cloth during the treatment and projecting fibres, and fuzz tend to be removed.  The process enables high grade broadcloth to be obtained from relatively poor grade material.  The treated material may be used as stiffening material for collars or cuffs.  A small quantity of ammonium sulphate may be added to the solution to increase stability.ALSO:Cotton or mixed piece goods are treated with a solution of the double salt of copper sulphate one molecular proportion, ammonia, four molecular proportions, and caustic soda, two molecular proportions, with excess of ammonia.

Title: Improvements relating to self-sealing bags or packets
IPC: B31B23/00
Filed: 1967-01-10
Abstract: 1,144,401. Making bags. E. S. & A. ROBINSON (RHODESIA) (PRIVATE) Ltd. 10 Jan., 1967 [21 Sept., 1966], No. 1347/67. Heading B5D. [Also in Divisions B2, B6, B8 and D1] Strips of pressure-sensitive adhesive are printed on opposite sides of a roll 7 (Fig. 3) of packaging material, the strips on one side being applied by adhesive-carrying portions 5 of a printing roll 4, while the strips on the other side are formed when the roll is pressed against an adhesive-bearing roll 11 by portions 14 of a backing roller 12. The roll may subsequently be formed into a bag in such a way that the two pressure-sensitive adhesive areas engage one another to form a re-usable seal for a flap (Fig. 9, not shown). The material passes through drying chambers 15, 16 before use. In forming bags portions are first cut out of the sides of the web by rotary cutters (18) (Fig. 4, not shown) fitted with suction devices (22) to carry the cut-off portions away. The cuts are disposed to leave flaps 24 (Fig. 8) which are subsequently folded inwards by pliers and pasted before the web is cut into lengths by a rotary cutter (26) (Fig. 7, not shown). Each length in turn is then tucked by a blade 28 (Fig. 8) into a slot in a rotating drum which delivers the completed bags to a stack 29. The web feed may include moving tapes 27.

Title: Improvements in or relating to electric motor control systems
IPC: H02P7/34
Filed: 1938-01-14
Abstract: 511,354. Automatic control systems. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. Jan. 14, 1938, No. 1362. Convention date, Jan. 16, 1937. [Class 38 (iv)] [Also in Group XXXVII] Speed. A motor 4 is supplied from a generator 1, the field 2 of which is connected in series with a coil 21 as one arm of a Wheatstone Bridge circuit having other resistance arms r1, r2, r4. A regulator Ar varies the potential applied to one diagonal of the bridge, while the other diagonal is fed from an alternating current source 16 through grid-controlled rectifiers 11, 12. The grid circuits are fed from the source 16 through resistances 26, 27, to which are connected a resistance 25 and a reactor coil 24. The coil 24 is wound on a core 20a which also carries the coil 21, a coil 22 energised by the motor armature voltage. When the regulator Ar is operated to apply a voltage to the bridge, the field 2 and the coil 21 receive current and the motor is started. The energisation of the coil 21 causes saturation of the core 20a and the rectifiers 11, 12, apply a voltage to the bridge to accelerate the growth of the field 2. As the motor speeds up the coils 22, 23, are energised to oppose the coil 21 in accordance with the motor speed. The current 'delivered by the rectifiers 11, 12, is then gradually reduced until the motor speed corresponds to the setting of the regulator Ar. In a modification, Fig. 4, not shown, the bridge circuit is not employed and the rectifiers deliver the whole of the field current. The core 20a has an additional coil energised in accordance with the setting of a speed regulator. Specifications 480,761 and 497,246 are referred to.

Title: Apparatus for unloading film sheet cassettes
IPC: G03D13/00
Filed: 1961-01-12
Abstract: 961,439. Apparatus for unloading cassettes. GEVAERT PHOTO-PRODUCTION N.V. Jan. 12, 1961 [Jan. 12, 1960], No. 1415/61. Heading G2A. Apparatus for unloading exposed films, particularly X-ray films, from cassettes comprises a magazine in which a number of cassettes may be stacked, means for indexing the magazine so that the cassettes contained therein are brought one by one to an unloading station, a mechanicallyoperated member for opening the cassette at said station, and another mechanically-operated member for extracting the film. The magazine is in the form of a vertical rack 2 having a number of shel shelves 7 of stepped section so as accommodate cassettes of different sizes. The magazine is raised to its highest position by a rack and pinion mechanism, and then lowered step by step so as to bring each shelf in turn opposite to the unloading station. A plate 8 at the rear of the shelves closes off in light-tight manner the compartment which is being unloaded. The cassettes are of the hingewise-opening type. Three separate operations are carried out mechanically: unlocking the cassette, opening it, and extracting the film therefrom. The unlocking member is in the form of a bar 25 which has a hook portion 26 at its front end. It pivots on an arm 28 rotatably mounted on a shaft 29. As it moves inwards towards the magazine, a pawl 30 which prevents it from rotating is dislodged, so allowing the bar to be rotated clockwise by a spring (not shown). The hook portion 26 has now entered the magazine through a slot therein, and engages in the lock 19 of the cassette. As the arm 28 rocks back again, the lock 19 is pulled open (Fig. 10). (For re-setting the lock, the arm 28 moves forwardly again, the lock closing under the action of a spring fitted within the cassette.) The cassette-opening mechanism comprises a bar 35 with a hook portion 36. The bar pivots on an arm 39 mounted on a shaft 40. As the arm 39 turns clockwise, the bar 35 is raised. The hook portion 36 swings in through the slot in the magazine, engages under the front of the cassette frame 18, and lifts it up (Fig. 10). For closing, the motions take place in the reverse direction. The film-gripping mechanism comprises a pair of jaws 42, 43, mounted respectively on members 44, 45, these being pivotally carried on side-arms 47, 48. The sidearms rotate on shaft 29. As they swing inwards towards the magazine, a locking member 51 is dislodged, which forces the jaws to move together, and so grip the film (Fig. 10). The gripping mechanism swings back again, so withdrawing the film, which is conveyed to rollers 56, 57, whence it passes on to a developing apparatus. The sequence of operations is entirely automatic, and is controlled by a system of cams and relays, Figs. (not shown) 11 and 12, which also operate various safety devices. Specifications 961,438 and 946,440 are referred to.

Title: Improvements in or relating to frequency dividers
Inventor: MORTLEY WILFRID SINDEN
IPC: H03B19/12
Filed: 1949-01-21
Abstract: 678,162. Valve frequency-dividing circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 22,1949 [Jan. 21, 1949], No. 1779/49. Class 40 (vi). In a frequency divider comprising a cascaded connection of divider stages an output frequency is obtained which has the phase stability of the input frequency by connecting a point in each divider stage through an impedance to a common load fed from a rectifier so that the voltages at these points pass through a negative (or positive peak) simultaneously and the output of every stage is in effect gated by the succeeding stages. The Figure shows a frequency divider comprising four stages of the type described in Specification 663,657. The input voltage is applied across inductor K and the tuned circuit L, C of each stage is tuned to the output frequency of that stage. A point on the tuned circuit of each stage is connected via a resistor R2 to a common lead W so that the voltages derived from each stage pass through a negative peak simultaneously and rectifier D is biased to conduct on the peak of the aggregate of these voltages. The output from each stage is thus effectively gated by the succeeding stage and an output pulse train at the required divided frequency is produced across load LR. An amplifier AM may be interposed between the common lead W and rectifier D. In a modification the output frequency of the divider chain synchronizes a flip-flop or similar circuit, the pulse output of which is filtered to give a sinusoidal output voltage. A number of additional divider stages may be interposed which are not connected to the common rectifier circuit.
