Filed: 1974-07-25
Abstract: 1469474 Self-levelling hydropneumatic suspension units; valves F M ALLINQUANT and J G ALLINQUANT 25 July 1974 [26 July 1973 9 Jan 1974] 32844/74 Headings F2S and F2V In a self-levelling suspension unit, pumping of liquid from one hydropneumatic chamber 11, to another 14, to alter the height of the unit, is effected by the reciprocating movements of a piston rod 7 in a pump chamber, constituted by the chamber 23, 24 in which the piston 6 works, which communicates with the first chamber 11 through an intake valve 18 and with the second chamber 14 through a delivery valve 28; and means are provided to prevent abrupt cessation of pumping and abrupt establishment of communication between the chambers 11, 14 when the suspension unit reaches its mean height. According to the invention, therefore, the pump chamber 23, 24 is separated by a first seal 27, which is a tight fit on a cylindrical portion 7b of the piston-rod 7, from a first compartment 30 communicating with one (14) of the chambers, and the first compartment 30 is itself separated by a second seal 31, which is also a tight fit on the portion 7b of the pistonrod 7, from a second compartment 34 communicating with the other chamber (11). The cylindrical portion 7b is followed by a tapered portion 7c which, as the unit approaches its mean height, comes firstly opposite the first seal 27 to produce a gradually increasing flow between the pump chamber 23, 24 and the first compartment 30 (by-passing the valve 28), and then opposite the second seal 31 to produce a gradually increasing connection between the two compartments 30, 34 (and thus the chambers 14 and 11). The connection between the compartment 34 and the chamber 11 is via an annular passage 3a, located between cylinders 2 and 3, and a jet 20. Valves, Fig. 4.-Instead of the flat plate 28 the delivery valve from the pump chamber may be constituted by three approximately spherical members 128 each held against a seat 126a to close a passage 126 by an annular spring 52 passing through all of them.

Title: Improvements in or relating to electrical cell apparatus for detecting chemical characteristics of liquids
IPC: G01N27/49
Filed: 1947-12-15
Abstract: 647,740. Determining physical qualities of materials. WALLACE & TIERNAN PRODUCTS, Inc. Dec. 15, 1947, No. 32987. Convention date, Dec. 24, 1946. [Class 37] Apparatus for electro-chemically measuring small quantities of oxidizing or reducing substances in liquids, e.g. residual chlorine in water, comprises an electrolytic cell of two electrolytes, one of which is a known quantity of the liquid being tested, separated by a porous wall, the output voltage being measured and reduced to a minimum value by a measured quantity of reagent, e.g. sodium arsenite, the electrode in the test liquid being a small distance from the porous wall, while the test liquid is agitated to obtain proper mixing of the liquid. In one embodiment (Fig. 1), a hollow cylindrical body 23 is surrounded at its lower end by a cup-shaped vessel 30 attached to the shaft 32 of a motor 35, and contains a quantity of electrolyte, e.g. sodium chloride; connection being made by a tubular electrode 45, coaxial with the shaft 32. Its lower end is wound with several turns of platinum wire 26, preferably in grooves 48 (Fig. 3), and between these grooves is another, deeper groove 49 packed with porous material, e.g. pressed cotton wick, having a series of holes 50 drilled through the wall of vessel 23 so that liquids on the inside and outside of the vessel are electrolytically in contact through the porous packing medium. The whole is supported in a cylindrical body 21 containing the liquid to be tested, which is agitated by rotation of the cup-shaped vessel 30. The voltage obtained between the electrodes 45, 26 is indicative of the strength of the residual chlorine in the test liquid. For titration purposes, a reagent, e.g. sodium arsenite solution for detecting residual chlorine, is pumped into a pipette 66 communicating with the liquid in vessel 21 via a clamped conduit. The voltage of the cell is reduced to a minimum by the addition of a measured quantity of reagent to a known volume.of test liquid, as indicated on a meter 75 (Fig. 4) which may be biassed by the rectified voltage obtained from an auxiliary winding 70 on the energizing winding 37 of the motor 35. Another form of electrolytic cell (Fig. 5) comprises an electrode 135 in a vessel 132 containing the electrolyte, and a second electrode comprising a spiral of platinum ribbon 142 wound on a cylindrical former 141 capable of being rotated by a motor 147. The former 141 is surrounded by a cylinder 130 of porous material, the whole being contained in a vessel 120, with the test liquid inside the cylinder 130, and vessel 120 containing the electrolyte fed from a vessel 132 by a conduit 131. In the titration process, the reagent sodium arsenite will indicate the amount of residual chlorine present in the hypochlorous or hypochlorite form. Response to chloramines is obtained by adding potassium iodide.

Title: Improvements in and relating to the production of therapeutically active preparations
IPC: A61K35/741
Filed: 1935-12-02
Abstract: Substances capable of dissolving carcinoma and sarcoma cells are obtained from the products resulting from the culture of normal intestinal bacteria of healthy individuals, (B. Coli), on fatty nutrient media, by methods suitable for obtaining high molecular fatty acids, e.g. liberating the acids by acidulation, extraction by organic solvents and fractional precipitation, the active substance being less soluble than the unwanted acids accompanying it.  Use may also be made of the superior solubility of the calcium salts of the active substance over those of the concomitant substances.  Suitable culture media are skimmed milk with the addition of vegetable oils or whole milk.  The products of bacterial growth are acidified, e.g. with phosphoric acid to pH4, and extracted with ether, petroleum ether &c.  The solution being slowly evaporated.  The addition of extracts of normal internal organs, e.g. liver, pancreas, thymus enhances the activity of the product.  According to the Specification as open to inspection under Sect. 91 active substances of the same kind are obtained from normal blood serum, especially dry serum, by extraction with acid alcohol, neutralization with ammonia, evaporation to dryness and treatment with sodium carbonate to obtain the sodium salt.  Urine also may be treated with kaolin under slightly acid conditions, centrifuged, the product rendered slightly alkaline and again shaken up; after separation of the adsorbent, the effective substance is precipitated from the liquid, e.g. by acetic acid, or is extracted with fatty acid solvents.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to secondary radar systems
Inventor: BARBER PETER FRANCIS
IPC: G01S13/76
Filed: 1959-10-01
Abstract: 856,969. Transponder apparatus, pulse radar. COSSOR Ltd., A. C. Oct. 1, 1959. No. 33370/59. Classes 40(5) and 40(7). A transponder is responsive to groups of pulses employed in either of two secondary radar systems in which response to side lobes radiated by directional antennae is suppressed. In the first system, two pulses A, B are transmitted the first, A, is a control pulse radiated from an omnidirectional antenna, and pulse B is an interrogating pulse radiated from a directional antenna. In the second system, first and third pulses A 1  ,B 1 , are transmitted from a directional antenna and a second pulse C 1 , is transmitted from an omnidirectional antenna. The transponder comprises an input terminal 10, Fig. 1 connected directly to one input of a first coincidence gate 11 and through a delay line 12 introducing a delay equal to the interval between pulses A, B to the second input of gate 11. The output of gate 11 is applied through suppressor gate 14, when open, to trigger the transponder transmitter. Fig. 2 (a) - (g) and Fig. 3 (h) - (m) show the waveforms to be found in Fig. 1 when the corresponding letters occur. The broken lines in Fig. 2, 3 corresponding to the positions of pulse B or of A 1 , B 1 , represent pulses received from the main radiating lobe, whereas full lines in these positions represent pulses received from side lobes. An output pulse is obtained from gate 11 if the received pulses are spaced by the correct interval e.g. 8 Ásec. and have sufficient amplitude to operate the gates. To suppress response to side lobes in the first system, the received signals are applied to an adder 19 by way of inverter 17 and by way of delay line 12, the output (e) of adder 19 being applied to one input of a second coincidence gate 20 to the other input of which, output (c) of gate 11 is applied. If pulse B is received from a side lobe, it has a smaller amplitude than pulse A, hence gate 20 will be operated (pulses D, E coinciding) and suppressor gate 14 will be closed by way of pulse generator 21. A delay 13 is included to enable the operator of gate 14 to take place before the output of gate 11 arrives. In the second system, waveform (h) is received, gate 11 is operated by pulses A 1 , B 1 , and response to a side lobe is suppressed by means of delay line 22 corresponding to the interval between A 1 , C 1  e.g. 2 Ásec., adder 25 which only has an output in the C 1 , position when reception is from a side lobe, and a third coincidence gate 27 operating to close suppressor gate 14. Pulse lengtheners 18, 24 may be included to facilitate the coincidence operation and the positions of inverters 17, 23 may be altered e.g. inverter 17 may be placed after delay line 12 and inverter 23 may be ommitted if variable amplifier 26 provides the necessary inversion.

Abstract: 486,870. Valve amplifying circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Dec. 10, 1936, No. 33948. Convention date, Dec. 10, 1935. [Class 40 (v)] A straight-line relationship on a logarithmic scale is obtained between input and output voltage in an amplifier arranged for volume expansion or contraction, by deriving the gaincontrol voltage from a non-linear potentiometer. Signals from the main amplifier channel are amplified in the valve Hv and rectified at Rgl, the rectified potential being applied to the potential divider Sp composed of devices such as contact rectifiers. Conductors 4, 5 apply the gain-control potential to the main amplifier channel (not shown). The amount of expansion or contraction is controlled by adjustable contact A and tapping points 1, 2, 3. This adjustment may be made simultaneously with the normal volume control of the main amplifier. The amount of expansion or contraction then depends upon volume control setting, overloading being avoided and the amplifier operated at maximum or any desired mean volume.

Abstract: 1529159 Cam-operated switches KIEPE ELEKTRIK GmbH 12 Aug 1977 [14 Aug 1976] 33997/77 Heading H1N A cam-actuated switching arrangement for electrically powered vehicles which has cams and switches for driving stages and braking stages and a lift-off device which selectively engages and disengages the switches with respect to their cams is characterized in that the drive cams and brake cams are fixed on a common cam-shaft and so arranged that during powered driving of the vehicle the brake cams are always positioned so as to provide, when engaged, at least approximately the braking stage suitable to the existing speed of the vehicle. Thus any particular drive stage will automatically set the brake cams to a corresponding brake stage but, as vehicle speed is not determined only by the drive stage, a further small rotation of the cam-shaft may be required. As shown a motor (10, Fig. 2, not shown) controls the cam-shaft 11 carrying disc cams 23 acting on drive switches 22 and disc cams 13 acting on brake switches 12. A motor 31 can actuate levers 15 to lift rollers 14 off the brake cams, or levers 25 to lift rollers 24 off the drive cams 23, thus enabling rapid change over from driving to braking. The use of disc cams and location of brake and drive switches on alternate sides of the cam-shaft reduces the overall length of the camshaft and an even more compact arrangement may be provided by arranging the switches in more than two rows.
