Abstract: In a telephone line feeding arrangement, the line current is monitored by a multi-resistor network (RpRs) and the output of the network applied to the inputs of an operational amplifier (A3). The output of this amplifier, which is a voltage whose value depends on the line current, is compared by a comparator (A4) with a reference voltage (VR) to produce a control voltage for a variable voltage (VVS), the output of which provides line feeding voltage. In an alternative, the monitoring is effected by connecting the two line wires each via a resistor to one of the inputs of an operational amplifier (A6) whose output is a voltage dependent on line voltage. This voltage is applied to an input of another operational amplifier (A7) where it is in effect added to a reference voltage (VR). The output of this amplifier (A7) is used to control the variable voltage source (VVS), which in turn controls a constant current source (CCS) whose output provides line current.

Abstract: A chimney block consists of a smooth inner tube (6) and a smooth outer tube (5) without solid interconnections, their relative positions being fixed by means of an intermediate insulating layer (7) which in slightly compressed state totally fills the interspace between the two tubes. The insulating layer comprises sheets of an inorganic fibrous or granular insulating material kept together by a bonding agent which melts or becomes plastic at a temperature substantially below the temperature in the chimney when in use. The tubes (5 and 6) are manufactured individually, and after positioning the insulating layer (7), loose metal sheets (9) are used to form a kind of chute into which the inner tube (6) can be inserted and pressed down in the outer tube (5) while compressing the insulating layer (7). <IMAGE>

Abstract: A changeover device (3,4,5) is provided with a transformer (6), and the modem circuit (1) feeds an alternating voltage signal over the transformer primary winding, as long as the modem circuit is activated for transmission and/or reception. The signal on the secondary side of an AC/DC convertor unit (9,10) is converted to one suitable for holding the changeover device (3,4,5) in poistion, and with the signal maintained, and only then, holds the line coupled to the modem circuit. The changeover device is a relay with rapid reaction time, whilst its 'on' time is 4 ms or less. The transformer (6) has an insulation voltage which is 4kV or more. To the transformer primary side the output of an AND type grid (8) is connected, which on its one input has a constant feed of an alternating voltage signal. On its other input a continuous signal is received suitable for coupling through the alternating voltage signal when the modem circuit is activated for transmission and/or reception.

Abstract: An ionospheric sounding system for frequency management of a HF communications system operates between a transmitter and a remote receiver and makes use of code-modulated narrow band sounding pulses transmitted at frequencies throughout the HF band. The code has an impulsive auto-correlation function and the frequency selection is pseudo-random. The code may be a two-part complementary code. Alternatively the code may be a selected one of a family of codes possessing high auto-correlation and low cross-correlation properties, thereby enabling communications management information to be conveyed by the choice of code. Measurements of signal and noise are made at the receiver for each transmitted frequency to assist establishing a HF communications link. Synchronous detection of the received signal is used, employing correlators (103, 104) in phase quadrature.

Abstract: "A breathing system for divers includes a breathing bag (211) from which the inhalation gas to the diver is delivered and to which the exhalation gas from the diver is supplied, a compressed gas source for the supply of breathing gas, and a pneumatic cylinder/piston unit (308, 209) operatively connected to the compressed bag source and having the piston (209) coupled to the breathing bag (211) to contract or expand the bag. A sensor responds to pressure variations in the breathing gas caused by the diver's inhalation and exhalation, and causes at least two valves and associated controls (173-205) to switch the compressed gas source to either side of the piston (209) in the pneumatic cylinder (208). The valves (176, 177) ensure that the breathing gas to and from the diver is maintained at a pressure approximately equal to the ambient pressure. When the sensor particularly comprises a diaphragm (170), the valve controls may be arranged to provide for increasing or decreasing the high-pressure gas flow supplied to the pneumatic cylinder (208) in dependence on the extent of movement of the diaphragm (170) in the direction in question.

Abstract: The guide bar for a motor-driven chain saw is provided for taking highest loading and is therefore made of solid material. For weight reduction, openings are provided in the guide bar which are closed off by cover plates that are flush with the flat sides of the guide bar. The cover plates are firmly joined to the base plate of the guide bar. By means of the hollow spaces inside the guide bar, a considerable weight reduction is attained, yet the stability of the guide bar is not substantially impaired as compared to a solid guide bar, since the hollow spaces are located in the zone that is neutral in terms of bending.

Abstract: The cooling tank has bottom and top parts, pref. of steel. An intermediary part forms its walls. A bolt extends through the tank, and with the aid of a nut holds the tank parts together. Packings are fitted in the joints between the parts. To the tank cooling chamber is connected an inlet pipe, passing through the bottom part, for liq. helium, the pipe incorporating a check valve. The alloy used for the tank walls contains copper and gold in equal propertions, and the pipe circuit moulded into them has an inlet for oxygen gas, and an outlet for liq. oxygen. Liq. helium is fed into the cooling chamber at a temp. of approx. -272 deg. C. The liq. helium is gasified on entry into the chamber, and its feed volume is such that the pressure rises to approx. 20-25 atm. Under this pressure, the helium gas temp. rises to approx. -200 deg. C. Oxygen gas is fed into the pipe circuit, and because of the very good heat conducting characteristics of the wall alloy, heat is emitted as the gas is cooled to liq. form, and absorbed by the walls for emission into the atmosphere. The gas is continuously cooled, and on its passage outwards through the outlet in liq. form has a temp. several degrees lower than its boiling point, i.e., -183 deg. C.

Abstract: A diverter-type mixing valve has a body formed with a chamber having opposite ends, a mixed-water feed passage opening into the chamber between its ends, a faucet outlet port opening into the chamber at one end thereof, a vent port opening into the chamber at the other end thereof, a diverter port also opening into the chamber at the other end thereof, and a restriction in the chamber between the feed passage and the ports at the other end. Mixed water is supplied under pressure to the feed passage. A diverter valve in the chamber directs flow from the feed passage out the faucet port when pressure between the restriction and the other end is greater than pressure between the restriction and one end and directs flow from the feed passage to the diverter port when pressure between the restriction and one end is greater than pressure between the restriction and the other end. A one-way vent valve in the vent port only permits flow through the vent port into the chamber and a one-way check valve associated with the diverter port only permits flow through the diverter port out of the chamber.
