Title: Apparatus and process for removing iron and/or other chemically reducing substances from potable water
Inventor: KREUSCH EDWARD G
IPC: C02F1/64
Filed: 1984-06-05
Abstract: The apparatus and process are for treating potable water having a pH between 5 and 9. The apparatus includes a tank (10) for receiving the water, which tank contains a bed of activated carbon (16). The untreated water is aerated prior to its communication with the activated carbon. All of the aerated water is allowed to flow through the bed and the activated carbon provides a catalytic action, whereby substantially all of the oxidation occurs throughout the bed of activated carbon and the use of chemical oxidizing agents is obviated. The tank provides a reaction site for oxidation in the catalyst, precipitation of the oxidized ions, and retention by filtration of the precipitated particles. <IMAGE>

Patent GB-2190986-A (GB)
Title: Spindle locking device
Inventor: COSSER HARRY FREDERICK
IPC: F16K31/44
Filed: 1986-05-28
Abstract: A spindle lock, for example on a valve that must not be opened during plant operation, such as drain valves for boilers, comprises a handle 12 rotatable with reference to a spindle 10 between limits defined by a stop formed by engagement of lug 109 fixed to the handle with one or other of lugs 107 or 108 of collar 106 on the spindle. The handle 12 may be turned clockwise until the stop is reached, where upon clockwise drive may be transmitted from the handle 12 to the spindle 10 and anti-clockwise until the other stop is reached, where upon anti-clockwise drive may be transmitted. It will also be appreciated that the handle 12 may be rotated through substantially 180 DEG without rotation of the spindle 10 to permit for example alignment of the hole 18 in handle portion 15 with the locking pin 19 to allow the spindle to be locked. Thus substantial changes in the valve fully closed position may be accommodated whilst still locking spindle 10. <IMAGE>

Title: Control of atmosphere in fruit stores
Inventor: JAMESON JOHN
IPC: B01D53/04
Filed: 1986-09-30
Abstract: In e.g. a refrigerated fruit store 1, the atmosphere is controlled to low levels of oxygen and carbon dioxide using an activated carbon bed 2, by continuously repeating the following cycle of operations:   (1) expose the carbon in the bed 2 to the atmosphere in the fruit store 1, until saturated with CO2 (e.g. 12 minutes); (2) evacuate the bed 2, down to 7 kPa, to the gas reservoir 5, whereby the O2 and N2 (but not CO2) are released in "fruit store" proportions into the reservoir (e.g. 2 minutes); (3) expose the bed 2 to air to purge it of the CO2 (e.g. 18 minutes);   (4) evacuate the bed 2 to waste (7ka is adequate) to remove O2 and N2, which would otherwise remain in the bed in substantially "air" proportions (i.e. excessive oxygen) (e.g. 2 minutes); (5) expose the bed 2 to the gas put in the reservoir 5 at operation (2) above, so that the bed 2 now contains O2 and N2 in "fruit store" proportions (e.g. 2 minutes); (1) expose the adsorptive medium to chamber atmosphere whilst releasing the gas from step (5) to the fruit store; and so forth indefinitely.   <IMAGE>

Patent GB-871213-A (GB)
Abstract: 871,213. Two-way transmission; loud-speaking systems. GYLLING & CO. A.B. May 13, 1959 [June 25, 1958; Nov. 29, 1958], No. 16498/59. Class 40 (4). In a two-way loud-speaker system with an amplifier for each direction of transmission a voice-operated directional switching stage in each amplifier is controlled by voltages derived from the input and output stages of the amplifier. As shown in Fig. 1 two channels are distinguished by suffixes a and b, microphones 3 being followed by amplifiers 5, 10 and 11, to drive loud-speakers 17. Vacuum tubes are shown but the use of transistors is said to be possible. A triode 21 receives input from winding 15 on the output transformer 13, and from the output of tube 5 over components 51, 52. The output of triode 21, over oppositely poled diodes 22 and 23 in the same envelope, drives the voltage of points A and B in opposite directions to similarly alter the voltages along the potential chains 27, 28, 29, thereby increasing the gain of one tube 10 and decreasing the gain of the other. Triodes 34 are cross-connected with each other and with the screen grids of tubes 10. Screen grid current taken by the tubes 10 is taken in shunt from the anode loads of opposite triodes 34 which, due to this fact, are not bi-stable despite cross-connection when no signal occurs in either channel. With a signal in channel a, say, triode 21a drives point A positive and point B negative so that the gain of tube 10a is increased and that of 10b is decreased by their second grids, while tube 34a becomes more, and tube 34b becomes less, conductive. Change in voltage at the anodes of tubes 34 alters the potential of the screen grids of tubes 10 and less screen grid current is taken with the consequence that the tubes 34 become bi-stable and tube 34a switches to full conduction. The screen grid of tube 10a therefore rises rapidly to further increase its gain. By shunting resistors 36 with capacitors the tubes 34 may act as a free-running multivibrator when no signal occurs in either channel, and consequently switch each channel in and out alternately preferably at a frequency of 2 to 10 cycles a second. When a signal appears in one channel the multivibrator is halted in the condition to open that channel. The multivibrator is damped by a capacitor connected between the screen grids of tubes 10 so as to increase its switching time and prevent plucking of the loud-speaker due to transients, see Fig. 2 (not shown). As shown in Fig. 3 the grid circuit of the triodes 21 may include capacitors 45 and non-linear resistors 20 so that for large-amplitude signals in a channel the triode will run into grid current and the output of the triode will fall, as will the gain of the channel, as capacitor 45 discharges and as with increasing voltage the resistance of the non-linear grid leak 20 falls.

Title: Improvements relating to hinges
Inventor: PETTERSSON STIG
IPC: E05D3/02
Filed: 1987-09-18
Abstract: A hinge which allows sliding movement of a door away from a frame followed by pivotal movement is formed by a slide (19) arranged to move in a guide (34) in a fixed part (6) in a direction perpendicular to the door frame (4) between an inner and an outer stop position. The slide (19) is provided with a ratchet mechanism (29, 30, 31, 41) arranged to arrest the slide in an outer position by being activated by the movable part (6) when the door is opened and swung out from the door frame. A snap lock (28) is provided to hold the movable part (10) in a position in which the door (1) is parallel to the door frame (4), with a force which is greater than the force necessary to move the slide (19). When the door (1) is influenced by a force to open the same the slide (19) is moved to its outer position whereupon the snap lock (22) is overcome to allow pivotal motion. Closure of the door requires the reverse sequence of movements. <IMAGE>

Title: Fabrication of resistors in microwave and other circuits
Inventor: MCCULLOCH DAVID JAMES
IPC: H01C17/26
Filed: 1987-12-16
Abstract: The resistance value of a resistor, e.g. a thin-film resistor in a microwave integrated circuit, is adjusted by reducing the thickness of the resistance region (1) without substantially changing its lateral dimensions since such a change could degrade the microwave characteristics of the circuit by distorting the electro-magnetic fields. This reduction in thickness (which increases the sheet resistance) can be effected by oxidising the upper surface of the resistance material by exposure to a pulsed UV laser beam (20) in an oxidizing atmosphere. The oxide (3) can be retained as a protective layer over the resistance material. <IMAGE>

Title: Modulator of an electromagnetic wave with coupled quantum wells, and an application to an electromagnetic wave detector
Inventor: VODJDANI NAKITA
IPC: G02F1/017
Filed: 1989-05-08
Abstract: A semiconductor structure defines two quantum wells (CP1, CP2), which are coupled via a barrier layer (CB). The application of an electric field, or doping, to the structure permits a transfer of electrons from one of the wells to the other. The electron-hole pairs are created by a pump wave, or alternatively by doping of one of the wells. This permits, especially, a double control by the pump wave and by the electric field; this provides a modulator having an "AND" function. <IMAGE>
