Patent GB-1016170-A (GB)
Title: Improvements in or relating to power-generating thermoelectric devices
IPC: H01L35/22
Filed: 1962-10-11
Abstract: 1,016,170. Thermoelectric devices. ENERGY CONVERSION LABORATORIES Inc. Oct. 11, 1962, [Oct. 16, 1961, May 28, 1962]. No. 38614/62. Heading H1K. A thermoelectric device comprises a lithium compound in contact with metallic lithium, the compound and the metal being provided with electrodes for obtaining electric current when a temperature difference is established between the compound and metal. The compound may be oxide, hydroxide, nitride, carbonate, orthophosphate, metaborate, silicate or mixtures thereof. The compound may be made by fully burning lithium in oxygen or air, and may be fused on to the lithium metal, or deposited mixed with a resinous binder which is subsequently burned off. Alternatively the lithium metal may be partially burned in air and then covered to stop the burning to provide the requisite compound coating. In one embodiment, Fig. 1, a disc 12 of lithium metal is placed in a metal cylinder 10 and a layer 14 of magnesium dust is placed on top and ignited, thereby igniting the lithium, a cover being placed over the top of the cylinder to snuff the ignition. Further layers are similarly added followed by an electrode 16. The device is heated at the top to produce the desired current. The device may be encapsulated in stainless steel or other metal and maintained in an inert atmosphere. Alternatively, as shown in Fig. 3, the lithium metal 41 coated with compound 43 is secured to a metal plate 42, to which is sealed a glass cover 40, heat being applied to plate 42 and the coating 43 remaining relatively cool due to radiation through the glass cover. The device is stated to work better in the presence of some water vapour.

Title: Improvements relating to the measurement of interlayer spacings between ferrous metal layers
Inventor: WALLEY JAMES WILLIAM
IPC: G01B3/22
Filed: 1957-12-12
Abstract: 886,675. Magnetic tests. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 10, 1958 [Dec. 12, 1957], No. 38680/57. Class 37. A method of determining the spacing between superposed ferrous plates, particularly in laminated pressure vessels for nuclear reactors, comprises subjecting the outer layer to a magnetic field between two polepieces and determining the field strength about the surface by means of a magnetometer calibrated in terms of interlayer spacing. Fig. 1 shows in elevation apparatus comprising a permanent magnet 2 and two ferromagnetic side limbs 3, 4, terminated in hinged polepieces 3a, 4a. The permanent magnet 2 may be replaced by an electromagnet fed from a stabilized D.C. supply. A magnetometer 8, shown in plan in Fig. 2, is slidable in a slotted brass member 9 and located between and above the polepieces 3a, 4a. The movement is shown in Figs. 3, 4 and comprises a shaft 10 journalled in jewelled bearings 11, and carrying a number of short permanent magnets 15 of the low permeability alloy Silmanal. A hair-spring 13 provides a restoring force so that the magnetic axes of the magnet 15 lie perpendicular to that of the magnet 2. The polepieces 3a, 4a are first applied to the outer steel plate 5, with the magnetic shunt 7 in place. The magnetometer 8 is then moved along the slotted member 9 until its axis is in the pole gap. The shunt 7 is then removed, magnetically saturating the outer plate 5, so that the deflection of the pointer 12 is dependent upon the air gap between the outer and inner plates 5, 6. It is stated that air gaps between 0.01 and 0.1 inches may be determined. Fig. 5 (not shown) relates to an alternative magnetometer movement using a single magnet. Specification 702,021 is referred to.

Title: Echo suppressor
IPC: H04B3/20
Filed: 1965-09-10
Abstract: 1,093,965. Echo suppressors. NIPPON ELECTRIC CO. Ltd. Sept. 10,1965 [Sept.10, 1964], No. 38821/65. Heading H4R. In a long-distance system such as one including a submarine cable or a communication satellite, in which the 4-wire terminal is connected to a local 2-wire line 14 through the usual hybrid arrangement 13, the leakage through the hybrid is measured and in accordance therewith current is fed into the transmitting path in counter-phase to balance the echo effect. As shown it is assumed that the line 14 leads to the called subscriber. A detector 311 responds to ring-back tone and sends a control pulse to clear a store 35. A second control pulse emitted by a bistable circuit 313 results in the movement of contacts 40, 41, 320 to the positions shown. A test pulse emitted through a gate 316 and wave-shaper 317 passes through the hybrid 131 to an analogue-todigital converter 33, where it is converted to 8-bit binary form and transferred to the circulating store 35. In one course, the second control pulse is interrupted, contacts 40, 41, 320 are restored, and the AD converter 33 now receives the leakage component of the calling subscriber's signals which is converted and fed to a buffer store 37 similar to 35. Both stores 35, 37 control a digital-to-analogue converter 43, the output from which represents the product of the two stored quantities and approximates to the echo component of the signals passing through the hybrid 13. This is integrated and fed in counter-phase to the transmitting terminal 17.

Abstract: 861,830. Continuous-casting machines. MANNESMANN A.G. Dec. 4, 1958 [Jan. 6, 1958], No. 39133/58. Class 83 (1). When continuously casting a hollow body around a mandrel, the casting is divided up during the initial stage into a number of separate sections which subsequently merge into a completely closed annular cross-section, so that the casting does not tightly grip the mandrel on shrinkage. The initial casting is divided by separating-plates a, a 1  on the starting-head e. The plates may be of asbestos, asbestos-covered metal or refractory; holes f or a bevelled edge ensure the uniform filling of the separate compartments.

Abstract: 1,273,035. Transhipping; lifting and lowering. CANADA, MINISTER OF NATIONAL DEFENCE. 12 Aug., 1969, No. 40221/69. Headings B8B and B8E. Means for vertically transferring a load carrier 9 between a helicopter 1 and a ship 5 which are subject to vertical relative movements comprises a constant tension guide cable 3 which laterally stabilizes the carrier 9 by extending therethrough, a load cable 71 detachably attached to the carrier 9 for controlling movement thereof, and a receiving post 11 on the ship adapted to receive and laterally stabilize the carrier 9 on the ship. When a load carrier 9 is to be picked up from the ship's deck, the load cable 71 depending from its winch in the helicopter, is coupled to the carrier 9 by a fitting on the end of the cable 71 engaging lock bolts in a central passage in the carrier, whereafter the carrier can be lifted from the post 11 on the deck. When the carrier 9 is to be lowered on to a ship, a messenger cable is payed out from its own winch in the helicopter and extends through the carrier passage until a coupling on the cable end can be attached to an end fitting on the constant tension cable 3 extending up through the post 11, the messenger cable being thereafter wound up to the helicopter where the end fitting on the cable 3 is held by locking catches. The carrier 9 may then be lowered by the load cable 71 down the guide cable 3 which is maintained at a constant tension by a winch system in the ship, until the central passage in the carrier engages the post 11 which includes a fluid and spring shock absorbing arrangement. This latter engagement causes the lock bolts between the carrier 9 and cable 71 to be released through lever and fluid system on the carrier, whereafter the guide cable 3 is released from the messenger cable coupling. The carrier further includes a fluid shock absorbing buffer between portions supporting the lock bolts and the load. In the embodiment of Fig. 8 (not shown) a fitting is provided on the helicopter for engagement with the receiving post whereby the helicopter may be winched down on to the deck of the ship. In another embodiment, Fig. 9 (not shown), the receiving post is mounted on a boom which extends outwardly from the ship.
