Title: Process of producing ammonium sulphate by the treatment with gypsum of an ammoniacal solution used for the scrubbing of gases
IPC: C01C1/244
Filed: 1928-03-24
Abstract: 307,037. Union Chimique Belge Soc. Anon. March 2, 1928, [Convention date]. Materials for purifying; purifier waste, revivifying.-In the process of treating distillation gases to separate acid impurities by washing with ammoniacal liquor as described in Specification 262,320, the washing liquor is saturated with ammonium sulphate whereby the addition of ammonia or ammonium carbonate which takes place in the scrubbing tower causes separation of crystal of ammonium sulphate. The scrubbing tower 2 receives the impure gases through an inlet 1, ammonia through an inlet 5 and washing liquor containing ammonium sulphate from an inlet 4. Ammonium sulphate crystals separate and are discharged into a vessel 18 in which they are washed with a portion of the solution from the pipe 4. The purified gas passes through an outlet 3. The used washing-liquor passes by a pipe 6 into a vessel 7 in which it is mixed with a suspension of calcium sulphate, which reacts with the ammonium salts in the liquor. The liquor passes through a filter 8 to separate calcium carbonate &c. and the filtrate together with water used in washing the calcium carbonate is passed through a heat exchanger 9 to a distilling apparatus 10 in which ammonia and volatile acids are separated. The residual solution of ammonium sulphate flows into an evaporator 19 in which it is brought to a concentration approaching saturation at ordinary temperature and is cooled by passage through the heat exchanger 9 and returned to the scrubbing column.

Abstract: 446,221. Apparatus for drying cigarettes &c. MOLINS, W. E., 2, Evelyn Street, Deptford, London. Oct. 24, 1934, No. 9007/35. Divided out of 446,077. [Class 34 (ii)] Apparatus for drying or conditioning articles, for example, cigarettes, comprises a rotatable chamber having a heated surface or surfaces therein, and a movable member arranged to extend through and reciprocate in the chamber to convey the articles therethrough and to be rotatable therewith, the member supporting the articles whilst moving in one direction, and being inverted before moving in the opposite direction during which latter movement the articles are supported by the walls of the chamber. In. the construction shown, cigarettes 1 are delivered from a belt 2 to fluted rollers 3 which deposit them on slidable trough-shaped members 6. These members are adapted to pass through drying or conditioning chambers 7 mounted on a circular carrier comprising discs 8, 9 carried by a spindle 10. The chambers 7 are heated by electric heating elements 27 arranged in series. As the carrier is rotated each trough 6 is engaged at one end by a fixed cam 13 whereby it is pushed into a chamber 7. The cigarettes in the trough fall out into the chamber as the trough becomes inverted during the movement of the carrier through half a revolution. During the second half of the revolution a cam 20 engages the end 17 of the trough 6 to move it back to position for receiving further cigarettes. As the carrier continues to rotate the cigarettes are intermittently moved through the carrier in a direction parallel to the axis of the spindle 10, finally falling on to a plate 21 leading to a conveyer 22. The troughs 6 are formed with slots to engage guide rails 18, 19 which are secured to the chambers 7 and are held detachably by springs in slots in the carrier. The apparatus is enclosed within shrouds 39 containing heat-resisting material 40. Specification 446,077 is referred to.

Abstract: 1307935 Digital transmission systems TELECOMMUNICATIONS RADIOELECTRIQUES ET TELEPHONIQUES TRT 25 Feb 1970 [26 Feb 1969 10 July 1969] 9010/70 Heading H4P  A multi-channel frequency-shift telegraphy receiver counts, for each channel, clock pulses between successive or alternate zero-crossings of the received signal, the count representing the length of cycle and hence frequency. Exemplary ranges of signal frequencies for 24 channels are disclosed and it is shown that a counter with a capacity of eight or two, for trivalent or bivalent codes, respectively, is all that is necessary for each channel. The counter state in its final cycle distinguishes the received one out of three or one out of two frequencies. In Fig. 2, which shows a trivalent code discriminator for one channel, zero-crossings of the received signal are detected by a limiting amplifier 19 generating a square wave signal which is differentiated at 20 to reset a counter 1 having a counting capacity of eight and which is fed with pulses from a crystal oscillator 7 and frequency divider 8. Prior to resetting the counter, the differentiated signal causes bistable elements 13, 14 to be reset by the counter output decoded by NAND gates 15, 16 and inverters 17, 18. The presence of one or the other of the complementary outputs of bi-stable elements 13, 14 indicating two of the three possible frequencies and the absence of both outputs indicating the third.

Title: Improved film driving mechanism for sound reproducing or like apparatus
IPC: F16F15/16
Filed: 1933-03-25
Abstract: 415,184. Flywheels. RADIO CORPORATION OF AMERICA, 570, Lexington Avenue, New York, U.S.A. March 25, 1933, No. 9098. Convention date, March 31, 1932. [Class 122 (i).] In sound-film reproducing, recording, &c. I apparatus the rotary film supporting member is carried by a shaft mounted on anti-friction bearings and which positively drives a very light member associated with or enclosing a flywheel, independently mounted on antifriction bearings and driven by the light member either magnetically or through a fluid, the rotary member and the shaft being driven solely by the film. The film 2 is drawn over a drum 1 which is fixed on a shaft 7 mounted on ball bearings 8, 9. A casing 10, of very light weight, is also fixed to the shaft, and encloses a flywheel 11, which can run freely on ball bearings 13 on the shaft. The space between the flywheel and the casing is filled with a fluid such as oil. The flywheel may be hollow, as shown in dotted lines, the main mass being near the periphery. As the film is drawn over the drum 1 by a sprocket 16 running at an approximately constant speed, it rotates the drum, the speed of which is kept uniform by the flywheel. The elasticity of the film causes the formation of loops above and below the drum when the flywheel has acquired its full speed, and slight variations in the speed of the driving sprocket merely alter the length of the loop 19. In a modification, the bearings for the flywheel are carried by a fixed stub shaft, in line with the shaft 7 and projecting into the casing 10 from the opposite side. In a further modification, Fig. 4, a disc 51 is mounted on the shaft 7 and drives the flywheel through an eddy-current disc 50 co-operating with magnets 52 on the flywheel. In another construction, Fig. 5, a flywheel designed to compensate for the effect of temperature changes is used. The body 11 of the flywheel is connected by springs 60 to a rim 11<1> which may be made like a compensated balance-wheel in a watch, and which is close to the wall of a casing 10 filled with oil. When the temperature changes, the rim advances towards or recedes from the casing, thereby compensating for change in viscosity of the oil. Alternatively, the casing 10 and the rim 11<1> may be made of metals having different coefficients of expansion. In another construction, Fig. 6, a flywheel is fixed yieldably with respect to an oil-container 71 by springs 72 attached to partitions 73. These extend into V-shaped notches in the flywheel and have apertures 74 through which the oil passes if relative motion between the flywheel and the casing occurs. The Specification as open to inspection under Sect. 91 also shows a construction, Fig. 4 (Cancelled), in which an eddy-current disc 40 is driven by magnets 41 energized by alternating current, providing a rotative force which overcomes the slight friction of the ball bearings. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in apparatus for forming and filling capsules
IPC: A61J3/07
Filed: 1942-07-02
Abstract: An apparatus, as shown in Fig. 1 of Specification 564,540, for forming and filling capsules comprises a pair of rotatable members 10 each having series of co-operating die-pockets 20 into which filler-material distends the capsule-forming material 14, a filler head having faces converging to a thin edge and provided with passages 50 in which are located tubes 70 tapered to conform with the edge of the filler head 20 as to extrude filler material at the points where the sheets of capsule material converge.  The curvatures of the filler head are designed not to be quite concentric with that of the corresponding roll, but to provide a slightly narrowing space towards the edge.  The packets 20 have within them plungers 22, gravity controlled and connected in axial series by pins 23; a sleeve 24 having limited play co-operates with the plungers to thrust the formed capsules out of the pockets 20.  The feeder head is mounted for limited universal movement by means of bolts 53 and heads 54 entering cavities 55. Specifications 395,546, 564,538, 564,539 and 564,540 are referred to.

Title: Vehicle drive mechanism
IPC: B60K17/34
Filed: 1952-04-10
Abstract: 708,581. Valves. TIMKEN DETROIT AXLE CO. April 10, 1952 [Sept. 25, 1951], No. 9204/52. Class 135. [Also in Groups XXIV and XXXI] On a motor vehicle having a main changespeed gear 10 driving two rear axles and a transfer box 11, driving a front-axle propeller-shaft the shift-rail 33 of a sliding dog clutch, which connects a driven spur-wheel of the transfer box to either a forward or reverse one-way sprag-type clutch driving the propeller shaft (see Group XXIV), is moved into its respective forward and reverse positions by the reverse shiftrail 14 of the main changespeed gear 10 through a hydraulic, compressed air, or suction control. In Figs. 1 and 4 compressed air is constantly supplied from a tank 18 through a pipe 23 to a space 91 between two unequal diaphragms 92, 97, fast on a rod 29 connected to the clutch shift-rod and yoke 33, and holds the rod 29 in the leftward position shown, selecting the forward one-way clutch. When the main reverse shift-rail 14 is moved from either forward or neutral positions into reverse it cams down a valve-plunger 24, Fig. 2, against the resistance of a flexible dome 65, which cuts off an exhaust path comprising a filter 59 and passages 58, 55, 62 communicating through a pipe 28 with a space 87 at the left of the diaphragm 92. Fig. 4, and then opens a spring-loaded discvalve 45 which supplies compressed air from a tank-pipe 22 through the pipe 28 to the diaphragm-space 87, where it overcomes the lesser leftward thrust of the pressure in 91 and moves the rod 29 to the extreme right, selecting the reverse clutch. A compression spring 84, between sliding collars 79, 82, on the rod 29 centralizes the latter in a neutral position from either end position in the absence of pressure either by accident or by intentional shut-off at 21. A restrictor 88 leading to the diaphragm chamber 87 produces gradual action to facilitate tooth mesh in the dog-clutch. In Figs. 5-7 (6 only shown) the clutch-rod 33 directly carries a piston centralized by two springs and having its opposite sides connected alternately to the pressure-tank and atmosphere by two separate valves 136, 137, Fig. 6, operated selectively by cam-tracks 134, 135 on the main reverse shift-rail 129. Each valve 136, 137 communicates with a respective piston side through pipes 126, 127 and, in the inoperative position, shown for the upper valve 136, vents the corresponding pipe 126 through the valve-stem 155, ports 156 and an exhaust connection 158, whilst in the lifted position, shown for the lower valve 137, the exhaust connection 158 is cut off by the lifted stem 155 seating on a spring-loaded disc-valve 151, which is then opened to supply pressure from an inlet 144 to the corresponding pipe 127. Fig. 6 shows the reverse position, from which movement of the shift-rail 129 one step leftwards to neutral exhausts both lines 126, 127 for spring neutralizing of the clutch-dog, whilst a further step in the same direction opens the upper valve to supply the line 126 selecting the forward clutch.
