Title: Improvements in apparatus of the injector type for producing a blast of air, gas or vapour with static pressure
IPC: F04F5/46
Filed: 1923-11-06
Abstract: 231,550. White, A. E., (Morgan Construction Co.). Nov. 6, 1923. Blast aspirators, injector. - In apparatus for the supply of air at increased pressure to support combustion in gas producers, and for similar purposes, by means of the inducing action of steam &c., several independent injectors, are employed to deliver in parallel to the same conduit, each having a number of inducing- fluid nozzles extending into the combining-cone of the diffuser and reaching almost to the throat. Provision is also made for preventing eddy and cross-currents where the several deliver cones of the diffusers discharge into the common delivery conduit, and also for a direct supply of inducing-fluid at will to the conduit at this point, in order that the amount of inducing- fluid present in the combined discharge conduit may be varied without the necessity of varying the quantity of induced fluid. The arrangement, which is described as applied to the water seal pan of a gas producer, comprises an inducing- steam supply pipe 12, Fig. 2, communicating with a number of steam boxes 11, one for each of the ejectors in parallel. From each box are supplied a number of nozzles 10 in parallel, reaching nearly to the throat 6 of a diffuser having a combining cone 5 and a delivery cone 7, and beyond the delivery cones and comprising guiding surfaces 9 adapted to promote the union of the several discharges into the common discharge conduit 8 without abrupt expansion resulting in eddy currents. In order to enable more or less steam to be included in the discharge conduit without alteration of the inducing action, there is a separate valve-controlled steam supply pipe 17 to apertures 18 communicating with the discharge. Fig. 5 shows a movable valve plate 15 for regulating the passage of air through ports 13 leading to the air chambers 3 of the injectors, the edges of the apertures being rounded for the prevention of noise.

Title: Demodulators for frequency shift keyed signals
IPC: H03D3/04
Filed: 1974-06-26
Abstract: 1458994 Frequency discriminators SIEMENS AG 26 June 1974 [2 July 1973] 28285/74 Heading H3A An f.m. demodulator, e.g. for a data receiver, comprises: a counter ZA which measures the interval between consecutive flanks of received signals by counting up a plurality of times from a starting-value to a maximum count; a control circuit ST which, at each flank, emits a transfer pulse which writes the instaneous count into a store SD and an erasing pulse which resets the counter; a digital/analogue converter DA coupled to the output of the store; and a lowpass filter coupled to the output of the digital/ analogue converter. The control circuit comprises three bi-stable circuits F1, F2, F3 coupled to form a shift register and three EXCLUSIVE- OR gates Al, A2, A3 with their inputs coupled to respective pairs of outputs from the shift register. Arrival of a first flank produces an output from gate A1 during a first clock pulse ZT which transfers the count of ZA to store SD. During the next clock pulse, gate A2 produces a reset pulse for the counter ZA, which then starts to count subsequent clock pulses until the next plank produces a subsequent output from A1 to transfer the new instantaneous count to the store. During the times that A1, A2 produce outputs A3 also produces an output which prevents the count from being incremented by clock pulses during these intervals. The demodulator is used in an FSK system and a D.C. bias may be superimposed on the output from the D/A converter to produce outputs of opposite polarity corresponding to logical "0" and "1" values of transmitted data.

Title: Improvements relating to the treatment of textiles with liquids
Inventor: HULSE GRAHAM
IPC: D06B1/02
Filed: 1953-10-19
Abstract: <PICT:0737401/IV (c)/1> <PICT:0737401/IV (c)/2> In a process for spraying textile materials with a liquid the liquid is taken up on a rotating wheel or disc and is spun off as a fine spray which is directed on to the material to be treated. Fig. 2 shows a textile spraying apparatus in which a series of discs 10 mounted on an axle 12 dip into treatment liquid 13 and are rotated at high speed so that liquid is taken up and sprayed off of the top edges of the discs through an opening 28 in the side wall of the container 11 on to the textile to be treated. The level of liquid 13 is maintained constant by a supply from reservoir 18 and the width of the aperture 28 may be adjusted by raising or lowering the compartment 30 and a baffleplate 34 is provided.  Any excess liquid which falls into compartment 30 or drip-tray 33 is returned to pool 13.  In a modification shown in Fig. 7 the spray-producer comprises four pairs of annular discs 33 mounted on a rotating shaft 35 which is housed in a box 34 having a false bottom 38 which is kept partly covered with treatment liquid fed in via supply pipe 54 from a glass syphon meter.  The size of the opening 40 through which the spray passes may be adjusted by means of a movable plate 45 mounted on axle 46.  A vertical baffle 44 is provided and also an angled baffle plate 41 which has a vertical portion 42 which is provided with teeth, Fig. 6 (not shown), the gaps in between which are positioned in line with the planes of rotation of the discs 10.  Outside of the wall 39 of the box 34 is mounted a catchpot 50 which can be rotated on an axle 51; when in the down position shown, any liquid which falls into it is discharged via a pipe.  A given treatment rate may be effected by feeding in a known quantity of liquid from pipe 54, catching the spray from discs 33 in catchpot 50 and measuring the liquid so caught.  The catchpot is then raised and the textile to be treated passed in front of opening 40. The process is described as of special use for treating textile fibres during or prior to spinning with silicon sols, for example of the type described in Specifications 607,696, 611,914, 626,847, 645,703, 649,896, 649,897, 654,850, [all in Group III], 654,858; 660,593, 662,423 and 663,013, [all in Group III].

Title: A process for the purification of sugar juices
IPC: C13B20/14
Filed: 1945-10-29
Abstract: The non-sugars are removed from sugar-containing liquids such as molasses or black-strap by bringing them into contact with cation - exchanging adsorbents and with synthetic resin anion-exchanging adsorbents, preferably in that order, said adsorbents being practically insoluble in said liquids, and regenerating the adsorbents after saturation by a treatment with a solution of an electrolyte.  The cation-exchanger may be the material obtained by the reaction of a dehydrating agent such as sulphuric acid or sulphur trioxide on carbonaceous matter such as anthracite at a temperature below 300 degrees C.  The anion-exchanger is preferably the resin obtained by condensing an aldehyde with an aromatic amine.  The exchangers, either in granular or powder form may be housed in an ebonite-lined iron vessel.  Regeneration is effected by means of sulphuric, sulphurous, or hydrochloric acids, or sodium carbonate, caustic soda, lime, sodium chloride or alkaline condensed factory waters.
