IPC: G03B27/72
Filed: 1956-08-30
Abstract: 875,659. Automatic control systems. OZALID CO. Ltd., and FIRMINGER, A. R. Aug. 30, 1957 [Aug. 30, 1956], No. 26493/56. Class 38 (4). [Also in Group XX] The speed of a motor 1 is varied by means of a manually operated control 4, the control being a variable tapping on a potentiometer 5. This is a logarithmic potentiometer so that equal increments of movement of the control produce progressively increasing or decreasing increments in the motor speed. (The potentiometer may be "semi-logarithmic," i.e. having a logarithmic characteristic, but modified at one end so that an actual zero setting is obtainable. ) As shown, the control gear 3 operated by the manual control 4 is of the type in which an error signal is obtained by comparing a voltage proportional to the speed of the motor with a reference voltage derived from the control 4. The motor is used to drive the conveyer means for the papers in a photo-copying machine, and so to control the exposure time. An alternative mechanical control is also described (see Group XX).

Title: Improvements in or relating to the production of pure carbon dioxide and pure sulphur dioxide
IPC: C01B17/50
Filed: 1933-09-26
Abstract: Carbon dioxide and sulphur dioxide are obtained in a continuous cyclic process in which sulphites such as calcium sulphite are treated with gases containing sulphur dioxide and the resulting bisulphites are treated with carbonates, e.g. calcium, magnesium, sodium or potassium carbonates, with the production of pure carbon dioxide and sulphites, a part of the sulphites thus obtained being returned to the first step of the cycle and the remainder being treated with an acid to liberate pure sulphur dioxide.  According to a modification an alkali sulphate, e.g. sodium sulphate is treated at the same time as calcium sulphite with gases containing sulphur dioxide, the alkali bisulphite obtained after the separation of calcium sulphate being treated with calcium carbonate with the production of carbon dioxide, calcium sulphite and alkali sulphite, the calcium sulphite being returned to the cycle, the alkali sulphite being caustified, say by means of lime, and the resulting sulphite after separation from the caustic lye being treated with an acid such as nitric or sulphuric acid to produce sulphur dioxide and salts such as calcium nitrate or sulphate.  Potassium sulphate may be used instead or sodium sulphate or barium carbonate instead of calcium carbonate.  The caustisation of the sodium sulphate may be omitted, the sulphite being treated directly with nitric acid, sodium nitrate being produced.

Abstract: 636,972. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. Oct. 6, 1947, No. 26817. Convention date, Oct. 5, 1946. [Class 106 (i)] Cyclically operating apparatus for registering data recorded by designations on a card in a four-position code comprises means for sensing the four positions, an accumulator of the type wherein each registering wheel is started to effect an entry by an impulse transmitted to a start magnet and is stopped by an impulse to a stop magnet or, at a fixed point in the cycle, by mechanical means, and is not affected by simultaneous impulses to both magnets, and means controlled by the sensing means for transmitting an impulse to the start magnet for entry of the digits 9, 8, 7, 5 at times 9, 8, 7, 5 cycle points respectively before the operation of the fixed point stopping means and for transmitting an impulse to the start magnet for entry of the digits 4, 3, 2, 1 and thereafter an impulse to the stop magnet, whereby eaoh one of the digits except 6 is entered by a single start and stop action. The accumulator, Fig. 1, is of known form in which magnets AM and SM initiate clutching and de-clutching, respectively, of an accumulator wheel 24 to and from a constantly-rotating ratchet-wheel 15, additional de-clutching means being provided by pins 52 and 53 which engage and lift a toothed arresting arm 21 at pre-arranged points in-the machine cycle. In addition to the usual transfer contacts .40, 41 co-operating with the transfer-cam-controlled arm 37, a pair of fixed contacts 59, 60 are provided which co-operate with a movable contact 58 operated by an arm 55 coupled to the accumulator wheel detent 25 whereby the contact 58 transfers from contact 59 to contact 60 each time the accumulator wheel 24 moves. Each digit is represented by perforations in the card 10, Fig. 4, at value positions whose sum equals the tens complement of the digit. The timed impulses in the circuits from the card sensing brushes 12 together with the control exercised by timed cam contacts C2, C3, C5 and C6 and the contacts 58, 59, 60 referred to above, direct impulses to the start magnets AM at appropriate times for entry of the digits represented and, in the case of digits 1, 2, 3 and 4, cause the stop magnets SM to be energized to terminate the entry. The entries for digits 5, 7, 8 and 9 are terminated mechanically by the pins 52 referred to above. The digit 6 is entered in two stages: 1+5. Subtraction is accomplished by closing a switch 75 causing energization of a magnet S and transfer of all its contacts a ... e to rearrange the circuits for complementary addition.

Abstract: 1,141,698. Feeding tobacco. TABAKUND INDUSTRIEMASCHINEN DRESDEN VEB. 10 June, 1967, No 26922/67. Heading A2C. In an apparatus for feeding tobacco for forming a continuous strand in a groove 22 of a rotating suction conveyer drum 21, tobacco picked off a spiked roller 1 by a beater roller 2 is pneumatically conveyed and accelerated in a suction nozzle 3 and a pipe 4 and passes an inertia separator 5 to an opening 8 where it enters a flow chamber 12 as a jet of tobacco 39 in which it is further accelerated by the suction applied to the drum 21 and forms a strand thereon. A fan 9 provides suction via a jacket 7 to the separator 5, the exhausted air being passed by the fan 9 to another inertia separator 31 which leads to a pipe 3 feeding into the nozzle 3. Air exhausted through the drum 21 is similarly fed to an inertia separator 34. The chamber 12 includes an upper wall 15, with air inlet openings 18 controlled by flaps 19, and terminates in a resilient plate 17. Opening of the flaps 19 deflects the jet of tobacco 39 downwards and may be augmented by the application of suction through ports (20) in the lower wall 16 of the chamber 12 (Fig. 4), and such adjustment alters the angle α between the plane of the crosssectional area 40, where the tobacco builds up on the drum 21, and the tangent to the drum surface at the line of impact with the jet 39 as shown. The optimum value of the angle α depends on the quality, especially the fibre length, of the tobacco used. Trimming wheels 36, 37 may be associated with the drum 21.

Two clamping plates 26, secured both sides of a split block 30 clamped on a bush 2 welded to a body 1, see also Fig. 2 (not shown), have crosspieces secured between them; one crosspiece carries the nozzle-baffle element 20, another crosspiece 25 carries a zero corrector 24 and a crosspiece 23 carries a bellows 22. The sensor operates as follows: - pneumatic pressure is fed to a relay 53, initially both pressures acting on diaphragms 9', 9 are equal, and an output signal from relay 53 created in bellows 22 controls the position of a baffle 34, Fig. 3, relative to a nozzle 33 supplied from the pneumatic relay 53. The lever 5 is acted on by the different pressures in spaces 16, 17 and the pressure in bellows 22 and when these pressures are equal, the sensor output will be a measure of the difference between the two first mentioned pressures. The crosspiece 23 can be adjusted along slot 32 in plates 26 and by a threaded projection 41 screwed in a ring 42 movable along the shafts, Fig. 4 (not shown). The zero corrector 24 is adjusted, through a hole 60, by tensioning a spring, Fig. 5 (not shown), attached at one end to the device and at the other to the shafts. The baffle 34 position relative to the nozzle 33 outlet is initially determined by an adjustable screw 35.

Title: Improvements in or relating to the manufacture of metal oxide adsorbent gels
IPC: B01J13/00
Filed: 1930-09-11
Abstract: Highly adsorbent metal oxide gels are produced by neutralizing a metal salt solution with acid or alkali so as to produce a nearly neutral mass which if acid is of acidity materially less than 0,1 N. and if alkaline is preferably less than 0,1 N., and washing and drying the colloidal precipitate formed.  For titanium oxide gels the reaction mass should be neutral or slightly acid, and for alumina gels the mass should be neutral or slightly alkaline.  For alumina gels the permissible maximum alkalinity varies inversely with the temperature; at -5 DEG  C. it may be 0,06 N. and at 20 DEG  C. it is 0,02 N., whereas at 60 DEG  C. it is only 0,002 N.  Titanium oxide gel may be made by pouring 50 c.c. of titanium chloride on to ice until it is diluted to 1200 c.c., neutralizing with 2 N. alkali to an acidity of 0,005 N. by the aid of bromphenol blue as indicator, washing the precipitate and drying first at 100 DEG  C. and then at 150-200 DEG  C.  Alternatively an acid solution of sodium titanate of ,4 N. acid which may be obtained by fusing titanium oxide with caustic soda and dissolving the mass in hydrochloric acid, is neutralized with caustic soda solution to 0,01 N. acid or less, preferably between 0,02 N. and 0,002 N. acid, which may be done with bromphenol blue as indicator.  Or an acid solution of titanium pyrosulphate, which may be made by adding titanium oxide to fused sodium pyrosulphate and dissolving the melt in 5 per cent sulphuric acid, is neutralized with caustic soda which may be of 1,5 N. to 2,3 N. strength, to an acidity of 0,004 to 0,005 N., the precipitate in the last two cases being treated as described above.  An alumina gel may be made by neutralizing a solution of aluminium sulphate with normal alkali such as soda or ammonia to give neutrality or slight alkalinity, preferably at 0 to -5 DEG  C., the precipitate being washed before or after the drying, preferably before; the drying is effected as described above.  Alternatively a sodium aluminate solution of about 5 per cent strength is neutralized with normal acid such as sulphuric acid at a low temperature not exceeding 20 DEG  C. so as to give a reaction mass which is alkaline but almost neutral. Mixed gels may be made by neutralizing a mixture of salts so as to give a reaction mixture of slight alkalinity such as 0,005 N.; titanium chloride or sulphate may be used with aluminium chloride, sulphate, or nitrate.  In an example equal volumes of 10 per cent solutions of aluminium and titanium sulphates are mixed, and neutralized at -2 DEG  C. with 1-2 N. ammonia to a slight alkalinity such as 0,005 N. Specifications 212,065 and 286,212, [both in Class 1 (iii), Oxides &c., Metallic], are referred to.  Reference has been directed by the Comptroller to Specification 289,890, [Class 1 (iii), Oxides &c., Metallic].
