Title: Stackable and nestable container
Inventor: FRATER ALLEN HATHAWAY
IPC: B65D21/04
Filed: 1967-10-30
Abstract: 1,146,196. Crates &c. CONTAINER DEVELOPMENT CORP. 30 Oct., 1967 [22 May, 1967], No. 49271/67. Heading B8P. A crate or other container has a number of spaced vertical columns along its wall or walls with gaps between, so arranged that when two such crates &c. are similarly aligned the tops of the columns on a lower crate &c. receive the bottoms of the columns of a like crate &c. stacked upon it, but when the crates are e.g. turned through 180 degrees, the columns of the upper crate slide into the recesses between the columns of the lower crate &c. and the two are in nested relationship. In one form, a crate of foamed plastics has a base 2, Fig. 1, with rectangular columns 4 spaced by gaps 6 and connected to a top rim 3. When two such crates similarly orientated are stacked, the bottoms of the columns 4 of the top crate rest on the tops 7 of the columns of the lower crate, Fig. 4 (not shown). By rotating the crates through 180 degrees relatively to each other, the columns 4 of the top crate can slide down the gaps 6 between the columns of the lower crate, so that one is nested within the other, Fig. 5 (not shown). In the stacked position, the rim 3 of the lower crate prevents lateral sliding of the top crate. The rim 3 may alternatively not extend beyond the tops of the columns 4, lateral sliding then being prevented by interengaging bosses and recesses on the top &c. faces of the columns. The columns 4 may alternatively be of circular, oval &c. cross-section. The crate &c. may be of square &c. cross-section, so that crates have to be misorientated by 90 degrees, instead of 180 degrees, for nesting. Feet (5), Fig. 2 (not shown), are provided on the lower side of the base 2. In another form, a crate has solid walls 11, 12, Figs. 8, 9, in which are formed columns 13. The upper and lower sections 14, 15 of the walls are offset to provide a ledge 16. In the nested relationship, the bottoms of the columns 13 of the top crate rest on the ledge 16 of the lower crate, Fig. 11 (not shown). In the stacked relationship, the bottoms of the columns 13 of the top crate rest on the upper ends 17 of the columns 13 of the lower crate, Fig. 12 (not shown). The crate has hand-holes 12, and feet (10), Fig. 7 (not shown). Instead of the rectangular crates shown, a container having the columns of the invention may be of circular, oval &c. shape.

Abstract: 513,039. Concentrating aqueous aliphatic acids by extraction and distillation. BRITISH CELANESE, Ltd. Dec. 16, 1937, No. 34856. Void. Convention date, Dec. 22, 1936. [Class 32] [Also in Group IV] Aqueous aliphatic acids are extracted by means of an aliphatic ester which contains at least 5 carbon atoms, in the presence of a small proportion of a salt which acts as a buffer to inhibit hydrolysis of the ester. The ester may be propyl, isopropyl or n butyl acetate ; and the buffering salt may be sodium or potassium acetate or sulphate. The extract may be subjected to fractional distillation to isolate the acid. The process may be employed for the extraction of formic, acetic, propionic, and butyric acids, and acids'from the fermentation of the juices of apples and grapes. In an example, aqueous acetic acid (31 per cent.) is mixed with 1 per cent. by volume of a concentrated aqueous solution of sodium sulphate. The resulting mixture is passed in countercurrent to n-propyl acetate through a series of columns partially packed with Raschig rings, the temperature being maintained at about 25‹C. The extract is subjected to fractional distillation so as to remove the n-propyl acetate together with any dissolved water in the form of an azeotropic mixture, leaving a highly concentrated acid.

Title: Electronic timepieces with digital display
IPC: G04G9/00
Filed: 1976-12-09
Abstract: 1534947 Electronic watches SUWA SEIKOSHA KK 9 Dec 1976 [10 Dec 1975] 51483/76 Heading G3T A digital electronic timepiece has day, month and year counters to provide a calendar display, the month and year counts being used to ensure that the calendar display is correct irrespective of the length of the month and whether it is a leap year or not. As described, signals from a quartz oscillator (1), Fig. 1 (not shown) pass through the usual divider (2) and counters (3) which produce seconds, minutes and hours signals. A selector circuit (17) permits either time or date figures to be shown on a display (20), e.g. of liquid crystal type, and a flicker circuit (19) causes part of the display to flicker when selected for correction. A 24 hour signal from the counters (3) is fed to a day of the week counter (5), to operate a corresponding display portion, and to binary counters 28, 29 which respectively count units and tens of the day of the month. Counters 30, 31 similarly count units and tens of the month, and counters 32, 33 count units and tens of the year. The outputs of the counters 28, 29 are connected to gates 37-40 and 70 which also receive gating signals from gates 41-45 responsive to which month it is and from gates 53, 54 responsive to whether it is a leap year. The gates 37-40 thus generate a signal on line 34 at the end of the month to reset the counters 28, 29 and advance the month unit counter 30. At the end of December a similar signal on line 35 resets the month counters and advances the year units counter 32. A setting system using only three switches for time and date correction is described. Date setting signals are fed in on lines 67-69, signals on lines 64-66 being used to prevent feeding forward of the counters, e.g. from date to month, during setting.

Abstract: 1499860 Zero force electrical connectors HOLLINGSEAD - PRYOR ENTERPRISES Inc 19 Dec 1975 [23 Dec 1974] 52007/75 Heading H2E A zero force electrical connector comprises a first connector shell 22 carrying a plurality of first contacts 84, and a second shell 104 carrying a plurality of second contacts 132 wherein movement of the shells 22, 104 one towards the other initially causes overlap of the contacts 84, 132 with no contact, subsequent further movement causing mating of the contacts 84, 132 through the action of a force transmitting means. As described, the connector is incorporated in an anionic racking system, shell 22 being connected to an electronic module and resiliently biased by springs 74 outwardly of its associated housing 30. Shell 104 is mounted on a tray on a rack and is resiliently biased by spring 120 transversely of the direction of movement of housing 30 or an arm 60 of the force transmitting means may be constructed so as to initially lift the shell 104. The force transmitting medium comprises a cam lever 54 pivotally mounted in the housing 30. Initial movement of the electronic module with housing 30 causes the contacts 132, 84 to overlap, Fig. 6, an actuating arm 58 of lever 54 abutting a cam actuating lip 136 on housing 112 which encloses shell 104. Further movement causes the lip 136 to rotate the lever 54 clock-wise, arm 60 of lever 54 forcing the shell 104 to move against the biasing spring 120 so as to mate the contacts 84, 132. Indexing pins 128 in slots 36 in housing 30 and similar pins and slots in housing 112 prevent mismatching of modules and trays. Power connectors (122), (124) (Fig. 4, not shown) and 70, 72 on the assembly 102 and housing 30 respectively connect, connectors 70, 72 being as required for the particular module used and may utilize coaxial cable or cooling air conduit. An overcentre spring force mechanism is attached to the cam lever 54 and comprises a spring retainer 62 on lever 54. A compression spring 65 within guide 66 spring biases a follower roller 64 against a cam track 46, the particular design thereof biasing the force arm 60 either clockwise or anti-clockwise. The overcentre force is thus transferred to the cam lever to ensure a locked operative position.

Title: Production of sulphur from calcium and/or sodium sulphate
Inventor: COGHILL DOUGLAS
IPC: C12P3/00
Filed: 1968-11-04
Abstract: 1,245,759. Sulphur; hydrogen disulphide. D. COGHILL. 4 Nov., 1968 [8 Nov., 1967], No. 52183/68.. Heading ClA. In a process for producing sulphur indirectly from calcium and/or sodium sulphates, the sulphates are reduced to hydrogen sulphide by bacteria growing under anaerobic conditions in a liquid culture medium containing sulphates and sodium chloride. The hydrogen sulphide is removed (e.g. by degassing under reduced pressure) from a solution withdrawn from the culture medium, and sulphur is obtained therefrom by conventional means, e.g. by burning in air. After removal of hydrogen sulphide, which may be freed from carbon dioxide by scrubbing with calcium hydroxide solution, the residual liquid may be recycled to the culture medium. Specified starting materials are gypsum, sodium sulphate and sulphate-containing organic wastes. In addition to sulphatereducing bacteria, such as desulphovibrio desulfuricans var. aestuarii, the culture medium may contain clostridium species, such as clostridium pasteurianum. The culture medium, which may be at ambient temperature, may also contain a nitrogen- and phosphorus-bearing fertilizer, limestone (as a source of CO 2  and as a pH buffer), sea-water and comminuted organic-matter, e.g. seaweed. In large-scale production (a proposed plant is described), process tanks containing gypsum and nutrient medium may be inoculated by opening into them sacks containing a mixture of the bacterial culture and plaster of Paris. The action of oxidizing bacteria which consume hydrogen sulphide is suppressed by using " matured " sea-water as a liquid medium, and maintaining the culture in deep tanks.
