Title: Absorption refrigeration systems, and compositions useful in such systems and as liquid coolants
Inventor: ARONSON DAVID
IPC: C09K5/04
Filed: 1968-11-26
Abstract: 1,208,467. Refrigerating; liquid coolants. WORTHINGTON CORP. 26 Nov., 1968, No. 55975/68. Headings F4H and F4U. An aqueous solution for use in an absorption refrigeration system or in a closed engine cooling circuit comprises lithium chloride or bromide and zinc chloride or bromide, the molar ratio of the lithium salt and the zinc salt being between 11: 1 and 1 : 2. The solution may also contain calcium chloride or bromide. The solution is particularly useful in an absorption system since it has a low vapour pressure which in turn allows the absorber to be air cooled rather than water cooled and since it may be highly concentrated without precipitation, thus allowing steam at at least 125 p.s.i.g. to be used to heat the generator. The Specification details the solution characteristics and gives exemplary operating temperatures of an absorption system.

Title: Improvements in and relating to pressurised water nuclear reactors
IPC: G21C1/00
Filed: 1966-12-20
Abstract: 1,117,829. Reactors. BABCOCK & WILCOX CO. 20 Dec., 1966 [20 Dec., 1965], No. 57058/66. Heading G6C. An integral, pressurized water reactor for marine use comprises a vertically disposed pressure vessel 12 in which the primary coolant is contained providing a liquid level 48, a sleeve 22 spaced inwardly from the pressure vessel 12 with the reactor core 16 positioned in its lower portion, and vertically extending steam generating and superheating tubes forming at least one tube bundle 36 disposed in a flow space for the primary coolant between the sleeve 22 and the pressure vessel 12 and extending from near the lower end of the core 16 to a location above its upper end, the liquid level 48 being between the upper end of the tube bundles 36 and the upper end of the core 16. The fluid within the tube bundles 36 is first heated in a nucleate boiling zone, then in a film boiling zone, and finally in a superheating zone. The liquid level 48 is in the superheating zone and the arrangement is such that the nucleate boiling zone will not become exposed to the vapour region of the primary coolant throughout a predetermined degree of movement of the ship resulting from its pitching and rolling. A plurality of spaced nozzles 40 extend horizontally for a short distance from the lower portion of the pressure vessel 12 before turning upwardly to circulating pumps 44. Coaxially within each nozzle 40 is a tube 42 extending through the core support cylinder 18. Each pump 44 receives primary coolant from the lower ends of the tube bundles 36 through the annular space between the nozzle 40 and the tube 42. The pumps 44 then return the fluid through the tubes 42 to the lower end of the core 16, from whence it flows upwardly in the sleeve 22 and out through openings 46 to the tube bundles 36. A plurality of nozzles 26 extend from the upper end of the pressure vessel 12, each having a tube sheet 28 at its outer end and an outer closure head 30 spaced from the tube sheet 28 to form plenum chambers 31, 31A. Alternate plenum chambers 31 serve as feedwater suppliers while the remaining plenum chambers 31A act as steam outlet collectors for the tube bundles 36.

Abstract: 1396880 Making thrust washers VANDERVELL PRODUCTS Ltd 9 March 1973 [9 Dec 1971] 57303/71 Heading B3A [Also in Division F2] A method of making a thrust washer from a flat strip of bearing material comprises the steps of rendering the strip tapered in cross-section, and then curving it in the plane of the strip into arcuate form, the thinner edge forming the inner edge of the arcuate strip, and the thickening of the inner edge which occurs on bending leaving a residual taper towards the inner edge. Fig. 2 shows a radial section through the finished washer comprising a steel back 11 and a bearing layer 12 of aluminium-tin, tin-based babbit, or lead-bronze. The back face 13 of the washer lies in a plane before and after bending. The taper may be up to 2 degrees, preferably 20 to 30 minutes. The strip may be tapered by rolling and parted into lengths each of which is then bent to semi-circular form. Alternatively, the tapered strip may be helically coiled under tension on to a mandrel, and required lengths parted off. Circular washers may be formed with abutting edges or clinch joints. The washer may have a coating of polymer-based bearing material, and further layers may be applied by spraying or electrodeposition. A locating projection may be pressed out of the edge of the strip after bending.

Patent GB-2046538-A (GB)
Title: Time delay circuits for controlling lights
IPC: H05B37/02
Filed: 1978-12-21
Abstract: An electrical time delay circuit provides a conducting path across a pair of terminals T1, T2 for a predetermined time period. The period is controlled by an electrical circuit 15 powered by a rechargeable battery 14. The battery 14 is recharged from a circuit 31 powered from a potential applied across the terminals N T2, which circuit 31 is operative when the conducting path is broken. When a switch 11 is closed, a capacitor 16 is charged and a triac 13 is switched on to energise lamps 12. The capacitor then discharges through resistors 23, 24 and at the end of the predetermined period the triac 13 is switched off to de-energise the lamps. A charging current then flows to the battery via the lamps 12, a resistor 32 and diodes 33, 34, the current being insufficient to cause lighting of the lamps. In a modification the triac is replaced by an electromechanical relay. <IMAGE>
