Title: Improvements in or relating to the preparation of macroporous resins and of ion exchange materials
IPC: C08F2/00
Filed: 1967-04-27
Abstract: Macroporous resins, capable of being converted into ion-exchange resins, are produced by the suspension copolymerization in water of at least one mono-olefinic monomer with at least one polyolefinic monomer in the presence of a saturated carboxylic acid which is insoluble or only sparingly soluble in water and is removed from the resin, the said acid comprising 5-50% of the total weight of monomers and acid.  The carboxylic acid is preferably separated from the resin by solubilization in the water of dispersion by means of a base.  The mono-olefinic monomer is preferably styrene; or acrylonitrile or acrylic or methacrylic esters. Preferred polyolefinic monomers are divinyl benzene, or a glycol dimethacrylate or a polyvinyl ether. The saturated carboxylic acids, used singly or as mixtures, may be aliphatic acids of at least 5 C atoms, aromatic acids or naphthenic acids, e.g. caprylic, 2-ethyl-1-hexanoic, lauric, stearic and benzoic acids. Example 1 describes the preparation of a porous resin comprising copolymerizing styrene and divinyl benzene in the presence of a styrenemaleic anhydride copolymer salt and 2-ethyl-1-hexanoic acid.  The resin obtained is cured by heating and is treated with NaOH solution to yield porous beads. The beads are heated with H2SO4 to effect sulphonation and yield a cationic-exchange material, or alternatively are chloromethylated and treated with trimethylamine to give an anionic-exchange resin.

Title: Improvements in or relating to flying machines
IPC: B64C29/00
Filed: 1931-07-07
Abstract: 371,691. Aircraft propelling, supporting, controlling, and landing gear. MEDVEDEFF, N. J., 543E, 132nd Street, New York, U.S.A. July 7, 1931, No. 19566. Convention date, July 7, 1930. [Class 4.] An aircraft is supported and propelled by the Magnus effect of rapidly rotating cylinders arranged in channels in the machine through which a current of air is forced. Pairs of fans 21, 22 driven by chain and bevel gearing from two engines 18, 19 draw air from the sides of the aircraft and direct it over two rapidly rotating rollers 23, 24. The air then enters a longitudinal channel 25 and into a channel 26 past a rapidly rotating transverse roller 27 to give forward propulsion. The rollers 23, 24 are driven in opposite directions by chain gear 54, 57 and bevel gear 51, 50, 55 from a vertical shaft 48 driven by chain gear from the two engines 18, 19. The roller 27 is driven by bevel gearing from the end of the roller 23. A hinged part 62 deflects the air from the passage 26 when forward propulsion is not required and is moved by a cable 65 connected to a handle 70 near the pilot's seat. To steer the machine one or other of two flaps 72 is brought against one half of the roller 27 by cables connected to pedals of which one is shown at 82, Fig. 3. Four similar flaps such as 87, 89, Fig. 2, are adapted to be brought individually against forward and rear portions of the rollers 23, 24 to control rolling and pitching. These flaps are deflected by arms on shafts 106, 110, Fig. 3, the shaft 110 being connected by a chain 111 to a shaft having a pinion 105. This pinion and a pinion 104 on the shaft 106 are engaged by independent lever segments 102, 103 engaged by arms on a lever 98, fore and aft movements of which deflect forward and rear flaps respectively. The lever 98 is independently duplicated on the other side of the pilot's seat. To compensate for variations in the total lift when these flaps are actuated the engine throttles are controlled by members 120, 121 engaged by the levers 102, 103. The speed of the rollers as a whole is controlled by a lever 122. A parachute is provided in a recess 123 ; inflated shock absorbers 125, 126 are secured beneath the machine ; an oil tank 20 is provided at the front of the machine and fuel tanks below the channel 25. The machine is divided into upper and lower compartments by flooring 13. Flaps 130, 131 assist in steering and stopping way.

Filed: 1921-07-21
Abstract: 187,691. Petter, A. G. July 21, 1921. Race games, mechanical.-Relates to mechanical race game apparatus of the kind wherein model race horses &c. are drawn along by flexible cords passing round independent winding barrels which may be coupled with a main drive for simultaneous operation. According to the present invention the flexible cords pass through apertures in a partition arranged at the winning post, the apertures being too small for the passage of the horses and being normally closed by hinged shutters which are pushed back by the horses and are thus caused to hoist indicators. Within a casing 10 are arranged a number of independent winding barrels 30 to which the horses 39 are connected by cords 33. A driving shaft 19 operated by a spring-driven motor may be moved longitudinally to bring its pinions 28 into gear with wheels 29 on the winding barrels and thus drive the barrels simultaneously and at the same speed. The horses are mounted on sledges 40 and may travel over irregularities in the couse passing finally up a slope 13, at the top of which the leading horse pushes back a flap 34 and is then obstructed from further advance thus arresting the driving shaft. The movement of the flap 34 raises the number plate 36 of the successful horse. Clips are provided within the casing for storing the horses, and a handle 26 is provided for winding up the motor. The lid of the casing is detachable and bears upon it a bookmaker's "slate."

Title: Phase modulation equipment
IPC: H04L27/20
Filed: 1972-04-27
Abstract: 1370396 Digital transmission; phase modulation SOC LANNIONNAISE D'ELECTRONIQUE 27 April 1972 [30 April 1971 15 March 1972] 19698/72 Heading H4P In a phase modulator receiving separate bit streams A, B from which signals α<SP>1</SP>, #<SP>1</SP> and α, # (defined in the Specification) are produced, the relative delay between incident and output signals is mT where m is an integer # 2 and T is the bit period. The arrangement is stated to allow an increase in bit rate by the multiple m. In an embodiment described m = 2 which renders the transmission system transparent to clock signals. In this case information is embodied in the phase shift between successive odd numbered bits and between successive even numbered bits, clock signals being recovered by applying alternately positive and negative phase shifts to successive bits which positive and negative shifts mutually cancel. Transcoder 10 receives separate bit streams A, B and provides logic signals α<SP>1</SP>, #<SP>1</SP> and α, # with relative delay mT. An oscillator 30 through splitter 31 provides one output to inversion or ring modulator 33, also receiving half modulation frequency F<SP>1</SP>, connected through attenuator 34 to adder 35 also receiving through delay line 32, which may be of coaxial type, an output from 31. To give a determined phase shift which is dependent on the amplitude ratio between inputs to 35, attentuator 34 is adjustable. Adder output passes to a further splitter 36 giving delayed and direct inputs to inverse modulators 39, 41 also receiving inputs α, # through amplifiers 38, 40 from transcoder 10 described in greater detail with respect to Fig. 1 (not shown); adder 42 receiving outputs from 39, 41 gives a phase modulated output 43. At the receiver distributer (50) Fig. 3 (not shown) divides input signals between outputs (a-c<SP>1</SP>) which are passed respectively to delays (53, 55) also to phase comparators (52, 54) connected to pulse regenerators (58, 59) which may comprise bi-stable circuits, also through (56, 57) to a band pass filter, amplifier, trigger circuit and frequency doubler (60-63), which may be an exclusive OR, the output from which is fed as a second input to (58, 59).  The signal to noise ratio may be increased by multiplying the recovered clock frequency by four and a modified arrangement incorporating this is shown in Fig. 4 (not shown).

Title: Improvements in or relating to the production of acrylic acid
Inventor: BELLRINGER FREDERICK JAMES
Filed: 1963-05-18
Abstract: Acrylic acid is made by reacting acrolein with molecular oxygen at elevated temperature in the vapour phase over an oxidation catalyst to give a reactor effluent containing acrylic acid and an amount of acrolein which is between 10 and 35% by weight of the acrolein originally fed to the reactor, quenching the gaseous reactions product with water or an aqueous acrylic acid solution to condense the acrylic acid and at least some of the acrolein, fractionally distilling the aqueous acrylic acid solution thus obtained to separate an overhead fraction comprising unreacted acrolein and a base product comprising aqueous acrylic acid substantially free from acrolein, and recycling the overhead acrolein fraction to the oxidation reaction.  Preferred features of the process include recovering acrolein from the residual gases from the quenching stage and recirculation to the oxidation stage, for example by scrubbing with water and distilling the resultant aqueous solution to recover acrolein as an overhead fraction, or alternatively using aqueous acrylic acid as the scrubbing medium, the use as oxidation catalyst a molybdate of bismuth, cobalt, tin, vanadium, iron, antimony, cerium, titanium, nickel or tungsten. The reaction may be carried out in the presence of a diluent gas, for example nitrogen or a mixture of steam and nitrogen.  The invention is described with reference to drawings accompanying the Provisional Specification (not shown) and an example is given containing comparative data of operation within the limits set forth by the claims and outside the scope of the claim.

Abstract: 714,808. Centrifugal blowers. SCHEID, A. M., SCHEID, E. M., and SCHEID, W. M., [trading as VORWERK & CO.], Aug. 7, 1952 [Aug. 16, 1951], No. 19914/52. Class 110(1) In a vacuum cleaner in which air leaving the impeller passes by way of an annular passage 7 and a discharge connection 8 to a dust collector, the inner wall 10 of the annular passage is tapered towards the impeller. A sewing thread drawn into the cleaner will be thrown off by the impeller into the passage 7 and, if it fails to pass directly into the discharge connection 8. will tend to be coiled around the conical inner wall 10. Provided that the apex angle # of the wall 10 is 20 degrees or more, the component in the direction of the impeller of the force acting on the thread will exceed the friction between the thread and the wall 10, and the thread will move towards the impeller into circles of smaller diameter, whereby it is loosened. After detachment, which is assisted by the sharp air current in the gap 11, the thread is swept by the impeller outflow against the outer wall of the channel 7 and is carried around to the discharge connection 8. A conical wall 9 is recessed so that the back plate 6 of the impeller lies flush with the peripheral part of the wall, which is rounded to merge with the wall 10. The back plate 6 may be flat instead of conical, and the passage 7 may be disposed as shown dotted. The front edges 5<SP>1</SP> of the impeller blades 5 form an angle a of 45 to 90 degrees with the impeller axis.
