Filed: 1968-11-20
Abstract: 1,182,400. Coinbox substations. TAMURA ELECTRIC WORKS. 20 Nov., 1968 [6 Dec., 1967], No. 55073/68. Headings H4K. In a prepayment substation, a coin collecting relay M is connected in circuit with parallel opposed rectifiers D1, D2 such that if the reply of the called party is signified by a reversal of line polarity (L2 becoming positive) it is brought up by current flow through D2 (L2, 1, m1 D2, M, t, L1) whereas if the reply is signified by an outbend A.C. signal relay A is energized whereby operating current for M flows through D1 (L1, t2, D4, M, D1, m1 &c.). If both types of reply signal occur simultaneously, M pulls up in the circuit L2, 1, m1 D2, M, D3, t2, L1. Once M has operated it is mechanically latched for the duration of the call. Contact CCL is automatically closed and latched when a coin is deposited, it and relay M being restored when the handset is replaced at the end of the call.

Abstract: 1450351 Soldering YATES INDUSTRIES Inc 3 Dec 1973 [1 Dec 1972] 55863/73 Heading B3R In processing a copper foil having a stainproofing coating containing hexavalent chromium ions, to improve the solder wettability of the coating, a compound such that at the soldering temperature it will react with the coating to expose the copper to the solder is applied to the coating. The foil may be for printed circuits and may be stain-proofed by electrolytic treatment in an aqueous electrolyte containing chromic acid and caustic and suitable compounds which are inert to the coating at 200-350‹ F. but react at 450-560‹ F. include hydrazine hydrochloride and ammonium chloride. The compound may be applied as a water solution by rolling, brushing or spraying if one side is to be treated or by dipping if both sides are to be treated. In an example a copper foil electrochemically treated to deposit on one side microcrystalline, modular, powdery copper is immersed in an aqueous chromic acid/sodium hydroxide electrolyte and then passed through a water spray. The foil then passes through a station where ammonium chloride solution is sprayed on the side opposite the one side. After drying solder wets the ammonium chloride treated side without a flux. The processed foil is, in another example, laminated on its side bearing the powdery copper to a substrate of epoxy glass fibre and the assembly is resist coated and etched to form a circuit which is then solder coated using water white rosin flux and wave soldering apparatus.

Abstract: 1285902 Submersible pumps AIRCO Inc 19 Nov 1969 [19 Nov 1968] 56575/69 Heading F1C A pumping system for a closed storage tank, e.g. a ship's tank or an underground or undersea tank, includes a pump assembly and an isolating chamber through which the assembly can be removed from the tank. A submersible pump and motor assembly 15, Fig. 1, especially for liquefied cryogenic gases, is located in a fixed discharge housing 13 supported adjacent the bottom of a ship's storage tank 28 by rails 17 which additionally act as guide rails during removal and replacement of the assembly from or into the tank. Before removal of the assembly, a cover 21 and an upper sealing plate (43), Fig. 2A (not shown) are removed, whereafter the assembly is raised into an isolation chamber 25 by cable 16 and hoist 24. Then a valve 27 is closed either manually, as by a wheel (89), or by hydraulic, pneumatic or electrical means, to isolate the interior of the chamber 25 from the tank interior. After purging the chamber 25 with inert gas, e.g. nitrogen, and removing two further sealing plates (37, 34), the assembly is lifted out of the chamber 25. The assembly has members 122 which centralize it during entry into chamber 25. Similarly the housing 13 has an upper internal frusto-conical surface (107), Fig. 2B (not shown), which centralizes the assembly when it is lowered back into the housing. The valve 27 can be locked in its closed position by at least one adjustable lug 91. The valve has a counterweight 125 to bias it towards its closed position. The entire discharge system 13, 14 can be removed from the tank by removing support plate 26 from the deck 11.

Title: Improvements in or relating to nuclear reactors

Filed: 1968-11-29
Abstract: 1,248,966. Controlling reactors. BABCOCK & WILCOX CO. 29 Nov., 1968 [30 Nov., 1967], No. 56739/68. Heading G6C. In a liquid cooled nuclear reactor, control rods are moved into position by the coolant flow through the-core. The rod, 30, fits loosely within the guide tubes 33, 34, is moved downwards by gravity into the core and urged upwards by the upward flow of coolant through the annular space, 36. With electromagnetically operated valve, 60, open, high pressure coolant flows into passageway 35 and holds rod 30 up, out of the reactor core. Normally, with valve 60 closed, the rod lies within the core and the hydraulically controlled valve assembly, 40, connects 35 to the lower plenum 27, via port 45, to allow coolant to enter 35 and cool the centre rod. An abnormal pressure drop across the reactor effects closure of 35 by 40, thus preventing the rod 30 being urged by fluid flow from the core. Normally, valve 42 floats between seats 49 and 53, supported by the upward coolant flow in 35, with rod 30 inserted in the core but with a predetermined flow rate, less than that required to raise rod 30, it engages seat 49. The valve 73 opens the flow path through 60 when coil 72 is energized. In the event of a coolant pressure loss, the increased coolant flow rate raises valve 73, against the coil to the closed position.

Title: Instrument for indicating static deformation of vehicle tyres
IPC: G01B5/213
Filed: 1973-12-12
Abstract: 1452965 Static measurements on vehicle tyres; type pressure gauges H DRIENDL 12 Dec 1973 [13 Dec 1972] 57621/73 Headings G1L and G1M The static deformation of a vehicle tyre in dependence upon internal pressure and loading is indicated by an instrument comprising a housing 1, a stationary deformation indicating scale 19 concentric with the axis of rotation of a pointer 7 that moves relative to the scale 19. A feeler arm 3 and a contact arm 5 each have one end pivotally mounted on a spindle 15 carried by the housing 1, a flexible non-extendable band 4 being connected to the opposite ends thereof and arranged to engage the flank of a tyre. An operating arm 6 is arranged to pivot the pointer 7, e.g. via a toothed segment 8, and is coupled to the feeler arm 3 by a slipping clutch 11. An adustable support arm 2 overlies the arm ends supporting the band 4 and is for engaging the wheel rim of the tyre. As described, arm 6 has a greater swinging range than arm 3 and, in the zero position of pointer 7, abuts adjustable stop 13. After adjustment of arm 2, arms 3, 5 are depressed together to move pointer 7 off the scale 19. Initial matching of band 4 with the tyre when the arm 2 is above the ground contact area returns the pointer 7 towards the zero position. Subsequently the arm 2 is abutted with the wheel rim in the ground contact area of the tyre, the band 4 being then applied to the loading zone. A true indication of the tyre deformation is thereby effected. The scale 19 comprises an inner area provided with coloured strips indicating "too much air"-"too little air". An outer pressure scale 21 is also provided, adjustable by means of a knurled ring 23. The amount by which a tyre is below the correct air-pressure may be determined by initially measuring the actual pressure and setting the outer pressure scale 21 so that the pointer coincides with this pressure. The required correct pressure may then be read from above the appropriate coloured strip. A measure of pressure difference i.e. between actual and correct, rather than the absolute atmosphere excess pressure, may also be determined. In this case, the zero point on the pressure scale is brought into coincidence with the pointer. The pressure difference may then be observed opposite the appropriate coloured strip.
