Abstract: 1,097,039. Mineral insulated cables. PLESSEY-U.K. Ltd. Dec. 7, 1964 [Dec. 12, 1963], No. 49182/63. Heading H1A. A cable insulated with magnesia contains titanium which on heating combines chemically with carbon dioxide and reacts with water vapour which lowers the insulation resistance of the cable. Hydrogen is also liberated to produce a reducing atmosphere which increases the resistivity of the insulant. The titanium may form a centre core of a cable with a stainless steel sheath although more than one titanium core may be used. The use of vanadium, zirconium and niobium instead of titanium is mentioned.

Title: Pressure control in heat exchange circuits
IPC: F25B49/02
Filed: 1967-11-07
Abstract: 1,210,074. Refrigerating; heating by circulation of fluids. AMERICAN AIR FILTER CO. Inc. 7 Nov., 1967 [8 Nov., 1966], No. 50635/67. Headings F4A, F4H and F4U. [Also in Division F1] In a heat transfer system of the type in which a fluid circulating in a closed circuit is alternately vaporized and condensed, a relatively non-condensible gas, e.g. nitrogen, is supplied to and removed from the system when the vapour pressure of the fluid is respectively below and above a predetermined value. As shown in Fig. 1, a refrigeration system comprises a condenser 2, a receiver 4 and a vessel 12 which is charged with nitrogen at relatively high pressure and is connected to the vapour space in the receiver by conduit 14 and to the top of the condenser by conduit 15. Valves 11, 16 in the respective conduits are only closed while vessel 12 is being charged. In operation, or when the system is shut down, nitrogen flows into the receiver through conduit 14 and thence into the condenser when the refrigerant vapour pressure is below a predetermined value so as to increase the high side pressure and reduce the effective condensing area of the condenser. The nitrogen tends to accumulate in the top of the condenser and is expelled therefrom through conduit 15 when the vapour pressure rises above said predetermined value. Vessel 12 may alternatively be disposed above the condenser. In the embodiment of Fig. 2 a heating system comprises a boiler 31, a turbine 32 receiving vapour from the boiler, a valveeontrolled turbine by-pass 44, a condenser 33 through which air to be heated is passed by a fan 37, a receiver 39 and a pump 38 for returning condensate to the boiler. The non-condensible gas is stored in a chamber 48 and passes to and from receiver 39 through conduit 49. Turbine 34 provides power for fan 37, a combustion air blower 45, pump 38 and a fuel pump 41. The supply of fuel is controlled by a valve 42 responsive to the temperature of the air leaving the condenser.

Title: Lobed composite synthetic filaments
IPC: D01D5/253
Filed: 1965-11-29
Abstract: A composite filament is characterized by a longitudinally extending core component consisting of a first synthetic organic polymeric material and a plurality of longitudinally extending lobe components having a denier of from 0.05 to 0.5 surrounding and adherent to the core component, at least part of the lobe components consisting of a second synthetic organic polymeric material ad being "readily separable" from the remainder of the composite filament, said core component having a higher denier than any of the lobe components. The denier of the core component may be from 1 to 4.  The first and second polymeric materials may be respectively a polyamide and a polyester or vice versa.  The core and lobe components may contain at least 2% by weight of an antistatic agent consisting of a poly (alkylene ether) with a molecular weight of 1,300 to 200,000.  The term "readily separable" is defined as the tendency for the lobe components consisting of the second polymeric material to separate from the remainder of the composite filament to form separate independent component filaments when the composite filament is subjected to a treatment such as vigorous mechanical agitation while it is immersed in boiling water.  The composite filaments of the invention may be formed by melt spinning through spinneret orofices of cruciform cross-section and draw-twisted into yarns. A knitted, woven or "non-woven" fabric may be formed of the composite filaments or yarns thereof and treated as above to cause their components to separate so that the fabric or yarn thereby becomes bulked.

Title: Telephone systems
IPC: H04Q3/62
Filed: 1974-11-25
Abstract: 1483745 Automatic exchange systems SIEMENS AG 25 Nov 1974 [30 Nov 1973] 50910/74 Heading H4K A number of digit receivers have access to a single unit, for evaluating the digits received, via an arrangement which prevents digits from two receivers being simultaneously transferred to the "evaluation" unit. Associated with each digit receiver is a respective logic circuit WK1-WK3 to the inputs TA1-TA6 of which is applied a 50 Hz pulse train. If for example a complete digit has been received by the digit receiver (2K1, not shown) with which is associated logic circuit WK1, an end of digit signal is applied to the input 1 of gate G2. This causes bi-stable device K1 to be set at the end of a 50 Hz pulse and in turn to set the output 4 of bi-stable R1 to "zero". On the occurence of the next 50 Hz pulse gate G3 is operated to cause gate G4 to produce a signal to cause the stored digit to be transferred to the "evaluation" unit. At the end of this 50 Hz pulse bi-stable device K1 is reset to cause gate G5 to produce a digit receiver resetting signal and at the same time to remove the end of digit signal from gate G2. The arrangement for preventing simultaneous transfer simply involves a connection from the output 2 of each bi-stable device K1-K3 to the gates such as G1 and G4 of the other devices, e.g. the link swa1. If end of digit signals should then be simultaneously applied to two logic circuits, the bi-stable devices K1-K3 are reset irrespective of the 50 Hz pulse train with the result that the gates G6, G8 &c. are enabled to produce a signal to inhibit digit transfer from both of the simultaneously calling digit receivers. Both the callers are then sent engaged tone. The arrangement apparently has application in PBX's with relatively low numbers of extensions, where the use of selector chains to provide a "one at a time" demand arrangement for the "evaluation" unit is not justified. The digit receiver and its associated logic circuit may be produced as an integrated chip. No details of the "evaluation" unit are given.

Abstract: 1,243,356. Agitating, mixing and circulating liquids. AGFA-GEVAERT A.G. 4 Nov., 1968, No. 52070/68. Heading B1C. [Also in Division G2] Light-sensitive silver salts, e.g. silver halides, are made by mixing an aqueous solution of a soluble silver salt e.g. AgNO 3  with an aqueous solution of a soluble metal salt e.g. KBr in a precipitation chamber which is stirred so intensively that the concentration of at least one of the reactants remains substantially constant throughout the chamber, and the dispersion of light-sensitive silver salt is then transferred to a ripening chamber which is of larger volume than the precipitation chamber, the precipitation chamber not being located inside the ripening chamber, and at least some of the dispersion in the ripening chamber being recycled to the precipitation chamber. In Fig. 1 silver salt and metal salt solutions are fed from containers 3 and 4 to precipitation chamber 1 and then pumped by pump 7 and line 5 to ripening chamber 2. Dispersion from the ripening chamber is recycled through line 6 to the precipitation chamber. The precipitation chamber may be the inner chamber of a rotary pump as in Fig. 2. In the apparatus of Fig. 2 dispersion is also recycled from the ripening chamber back to the precipitation chamber, and in embodiments the reacting solutions may begin in the storage containers 3 and 4 or 9 and 10, or one solution may begin in a storage container and the other in the ripening chamber. Gelatin may be present or absent during the precipitation.

A rolling sleeve-type seal for use between a piston and a cylinder or between a reciprocable rod and a housing'comprises a plurality of layers of elastic material which are connected to one another at their edges or over their entire area. The layers when connected to one another only at their edges may have different lengths so that when the seal is mounted in position, the inner edges lie in one plane and the outer edges also lie in one plane. When secured to one another over their entire area, they may be prestressed beforehand, the innermost layer to a greater extent than the outermost layer. The innermost layer may be subjected to' a tensile stress and the outermost layer to a compressive stress. One or more of the layers may be made of a material different from that of the other layers. The concave or the convex side of the sleeve may face the working space. Fig. 5 shows a rolling sleeve-type seal 3 between a piston 1 and a cylinder 2. The layers are secured to one another only at their edges. A lubricant may be provided between the layers to increase the flexibility of the seal and reduce internal friction and wear. The seal is supported on its convex side, remote from the working space 4, by a liquid contained in an annular space 5 which, due to the construction of the piston and cylinder, is kept constant during the operation of the piston so that the pressure differential across the diaphragm once adjusted will not vary.

Relates to an apparatus for determining the natural resonance frequency (2#) of a structure, comprising a driving transducer 6 (Fig. 3) which sets the structure oscillating at twice the frequency (w) of the electrical energy fed to the transducer 6, and a magnetic pick-up 7, and means to prevent the pick-up producing voltage at other than the resonance frequency, the structure having a ferromagnetic layer adjacent the transducers. The transducer 6 is connected in a bridge circuit and acts simultaneously as a driving and pick-up transducer. Equilibrium of the bridge exists when the structure 8 is at rest. When the structure 8 is vibrating an induced voltage E M  appears between terminals A and C, which is applied, via a band pass filter 12 tuned to reject harmonics of w and a limiter 11 to stabilize the amplitude of vibration to a predetermined value, as feedback to an amplifier 9 thereby providing a self-oscillation when its phase shift and gain are such that oscillating conditions are fulfilled. The drive circuit thus does not contain signals at the frequency of vibration 2w of the structure. The pick-up 7 is a variable reluctance type comprising a permanent magnet and produces a voltage when placed near the structure 8. A filter 13 rejects any parisitic voltage at frequency w due to stray radiation from the driving transducer. Alternatively the drive transducer may be electrostatic Figs. 4, 5 (not shown) the structure 8 having an adjacent conductive surface.
