Title: Improvements in or relating to Contact Members, their method of Mounting and Means for Extracting them from a Connector Block
Inventor: CARTWRIGHT JOHN ANTHONY
IPC: H01R12/72
Filed: 1966-05-27
Abstract: 1,184,785. Pliers. PAINTON & CO. Ltd. 17 Aug., 1967 [27 May, 1966; 7 Feb., 1967], Nos. 24007/66 and 37999/67. Divided out of 1,184,786. Heading B4W. [Also in Division H2] Pliers 50 for extracting contacts from a connector housing (see Division H2) comprise a pair of pivoted arms terminating, respectively, in a head 57 and a contact-releasing probe 51, and having hand grips 53, 54. Compression of the hand grips 53, 54 against a spring 56 causes a contact stem 27, which is received in a slot 58 in the grip 53 to be gripped between the head 57 and probe 51, and enables the contact to be pulled from the housing. In a modification (Fig. 4, not shown) the probe (74) is of cruciform cross-section.

Title: Improvements in single-pipe heating systems
IPC: F24D3/10
Filed: 1962-10-09
Abstract: 1,015,372. Pipe couplings. A. SCHON, [trading as RIETSCHEL & HENNEBERG.]. Oct. 9, 1962 [Oct. 10, 1961], No. 38207/62 Heading F2G. [Also in Division F4]. The ends of sections 10, 11 of horizontal heating pipes in a dwelling, preferably rectangular in section so that they fit in the corner between wall and floor, are connected by a bridging pipe 12 which is screwed on to threaded nipples 14, 16 projecting from the sides of the pipe sections near their closed ends. Instead of the bridging pipe being U-shaped, Fig. 1, it may comprise a short straight pipe length with an elbow at each end. In another modification an elbow may be welded to each of the sections 10, 11 and these elbows connected by a sleeve having left-handed and right-handed screw threads. Fig. 5, which is a sectional plan through an outside wall 24 and inside walls 25, shows four ways in which the bridging pipes 27, 28, 29, 30 may be disposed, the pipe 30 entering a cavity in the floor.

Title: Signal processing circuit
IPC: G01G19/18
Filed: 1975-09-17
Abstract: 1481257 Measuring voltage BROKEN HILL PTY CO Ltd 17 Sept 1975 [18 Sept 1974] 38220/75 Heading G1U In measuring a D.C. signal which may be accompanied by A.C. and random components, the period of the A.C. component is determined the input signal is integrated over a complete period thereof and the integral divided by the measured period to provide an average value. The composite input signal EL, is filtered 1 and applied to a phaselocked loop frequency discriminator which provides an output proportional to the frequency of the main A.C. component.. The input signal is integrated by conversion 3 to a proportional frequency signal which is counted in an integrator 4 reset at times determined by the output of the phase-locked loop 2. The integrated values are stored 5. A reference, time base, oscillator 8 output is integrated 9 over a time determined by the phase-locked loop output, to provide a stored 10 digital number representing the period of the A.C. components. A divider 6 divides the integrator output by the measured period to provide an average value of the D.C. input, free from effects of the A.C. and random components. This is converted 7 to analogue form. In the Fig. 6 embodiment (not shown), analogue integration and division is used, and in the Fig. 7 embodiment (also not shown), the integral is measured by determining the time taken to reduce the integrator output to zero using a negative reference input (i.e. the dual-slope integration method).

Filed: 1964-09-21
Abstract: 1,023,676. Directional couplers. MULLARD Ltd. Sept. 21, 1964, No. 38384/64. Heading H1W. A directional coupler uses printed lines of the type comprising an inner conductor located between a pair of outer ground planes. Two lines LC extend parallel to each other in the same plane over a coupling interval and, in order to increase the capacitance between them, two planar conductors P are inserted between the coupled lines and the ground planes which, in this instance, are provided by the casing of the device. The conductors P are not connected to other parts of the coupler. They may be printed on the outer surfaces of two dielectric sheets and the lines LC may be printed on one or both of the contiguous inner surfaces of these sheets. Lead-in lines LF, connected to coaxial sockets A, B, C, D, are slightly wider than the coupling lines LF and, in order to preserve impedance matching, the distance between the ground planes is less in the vicinity of the lead-in lines than in the vicinity of the coupling lines. The coupling interval is one quarter-wavelength at the midband frequency. The coupling factor at 1À8 Gc/s. may be 2-5 db.

Abstract: In the process of the principal patent, the inner wall of a glass tube is covered by at least one glass layer of higher refractive index than that of the tube, forming the core of the optical fibre. In the present process, the coating of the inner wall of the glass tube (11) is carried out by applying a material layer (10) which is converted, under the action of heat, into a glass layer of higher refractive index than that of the tube. To this end, for example, a tube of silicon dioxide is coated with germanium dioxide or germanium dioxide-containing material, the coating material being deposited by a reaction in which hydrogen and compounds thereof are excluded. <IMAGE>

The prepolymer may be represented by the general formula wherein A represents a radical obtained by removing the hydroxyl groups from an n-functional polyalkylene oxide polyol Mol. Wt. 500- 8,000 in which from 5 to 100% of the alkylene oxide units are ethylene oxide units; R represents a divalent radical obtained by removing the isocyanate groups from an organic diisocyanate having a Mol. Wt. of from 112 to 1,000 and n represents an integer of from 2 to 4. Suitable polyols are those comprising from 8 to 70% of ethylene oxide units and from 92 to 30% of propylene oxide units. In a typical example a trifunctional polyether, 17% of whose alkylene oxide segments consist of terminal ethylene oxide segments and 83% consist of propylene oxide segments is reacted with hexamethylene diisocyanate and unreacted diisocyanate subsequently removed from the reaction product by thin layer distillation in vacuo to give the prepolymer (NCO content 3À6%) which is mixed in water containing emulsifying agents, with sodium bisulphite to yield a water dilutable 30% bisulphite adduct solution. The aqueous adduct solutions may be used for treating textiles of natural or synthetic fibres and as binders for chip board, as adhesives and as crosslinking agents in emulsions of isocyanatereactive precondensates.
