Patent GB-330721-A (GB)
IPC: E05B65/00
Filed: 1929-05-09
Abstract: 330,721. Mõdler, M. Feb. 20, 1929, [Convention date]. Hasp fastenings; multiple fastenings for wardrobetrunk drawers.-A hinged hasp - plate is pivotally mounted at a on the body l of the trunk so that it can be moved into locking engagement with a socket n on the lid m to fasten the trunk, or with a socket f on the trunk. Movement to the latter position operates a sliding rod d within the trunk to engage hooks e formed thereon with staples h provided on the individual drawers, not indicated, so that the drawers mav be locked when the lid is released. Operation of the rod, which is slightly flexible to avoid breakage by deformation of the trunk in transit, may be effected by link connection with the hasp, as shown, or by other means such as sprocket and chain, bevel gear, or cam. One or more additional hasp-fastenings b may be mounted on the lid to engage sockets p on the trunk, and adapted to be released automatically by projection o on the rod d when the rod is raised. The hooks may be downwardly directed and engage the staples when rod d is lowered so that drawers and trunk may be locked simultaneously. Sockets n, f may be so disposed that the upper hasp is rotatable through 180 degrees to reciprocate the rod, the hooks being in engagement with the staples with the hasp in either of its extreme positions and disengaged in intermediate position. Selective locking of the drawers may be effected by having hooks of different lengths to engage the staples at different parts of the stroke of rod d, a corresponding number of sockets f being provided to lock the rod at various positions.

Abstract: 809,840. Mounting circuit components; direct connections between conductors. STANDARD TELEPHONES & CABLES Ltd. May 3, 1957 [May 10, 1956], No. 14539/56. Classes 37 and 38 (1). A mounting arrangement for electrical components comprises a row of base members each carrying plug blades projecting on both sides of said members, component mounting plates jacked on to one end of said plug blades and a printed circuit board connected to the other end of said plug blades which pass through holes in said board. Fig. 1 shows base plugs 5 arranged in a row on rods 4 between uprights 2, 3. Each rod 4 is provided with flats 22, Fig. 12, hence the base plugs may be removed by rotating the rods so that the flats are aligned with restrictions 21 in the base plugs 5, Fig. 4. One end of each rod is reduced in diameter to fit into a hole in upright 2 while the other end is provided with further flats 25 at an angle to flats 22 so that the rod may be retained in a keyhole-shaped opening in uprights 3. The rods 4 are secured by one pin passing through both rods. The lower rod 4 may be replaced by a supporting bar against which the plug bases may rest. Each resilient insulating base plug 5 has limbs 9, 10 with grooves 15 to act as guides for jack-in units 6. Fig. 1 shows one of these units comprising an insulating component mounting - plate 27 attached by metal clips to a socket block 28 and carrying an aluminium or plastic handle 31 and a metal heat shield 30 on which valves and other components may be mounted. The handle 31 is provided with grooved arms 36, 37 into which the plate 27 is slid and is retained by barbs 35, Fig. 6, engaging recesses at the ends of the grooves. The heat shield 30 is retained between shoulders 40 on the handle 31 and the end of the plate 27. One limb of each base plug 5 is recessed at 18 to locate the projection 33, Fig. 6, which prevents reverse entry. A stop 19 may be provided on certain base plugs to prevent the insertion of jack-in units not provided with a cut-away corner. A conducting strip, Fig. 16. not shown, having prongs corresponding to the spacing of holes in the plate 27 may be used to interconnect components or printed circuits on the board. Vacant spaces in the rows may be filled with dummy jack-in units to form a continuous heat shield. The dummy base plugs may have blades 12 omitted. Direct connections between comductors.-The inner ends, Fig. 18, of the plug blades pass through holes in a printed circuit board 7 and are connected to wires 49 soldered to the printed conductors by wrapping the wires 49 around them or by the use of a separate binding wire 65, as described in Specification 753,605.

Abstract: 1362111 Removing lead deposits from steam stills PPG INDUSTRIES Inc 29 March 1972 14652/72 Heading F2N [Also in Division B3] In a still 10, used for steam distilling tetraalkyl-lead from a mixture of tetra-alkyl-lead and lead particles suspended in water, deposits 27a, 27b of lead which build up on the still walls are removed by a fluid jet from nozzle 9. The fluid may be water, trichloroethylene, perchloroethylene, mineral acid solution or suspensions of sand and other solids in water. Initially, an area of the inner surface of a still wall may be cleared of lead deposit, e.g. by chiselling or by directing the fluid jet against the deposit overlying this area for a sufficient period of time. Subsequently, the jet is directed against this cleared area until adjacent deposits are dislodged to expose a further area, against which the jet is then directed. This process continues, directing the jet at freshly exposed areas until the still is substantially free of lead deposits.

Title: Apparatus for and Method of Collecting Gas Chromatographic Fractions
IPC: G01N30/84
Filed: 1967-04-03
Abstract: 1,183,189. Gas chromatography. ABCOR, Inc. 3 April, 1967 [4 April, 1966], No. 15092/67. Heading B1L. Gas fractions from a gas effluent of a gas chromatographic system are collected by gradually cooling down the gas effluent stream along a flow path by providing a temperature gradient along the path, whereby at least part of the gas fraction is condensed. The formation of aerosol particles, which are difficult to condense, is said to be thereby inhibited. In a particular embodiment a sample, e.g. a mixture of cis- and trans-pentene-2, is injected into a chromatography column with a carrier gas, e.g. helium, and emerges from the column separated into its various fractions. Each fraction is then passed, via a separate valve, into a corresponding tube or coil located inside an insulated cooling chamber whereby its temperature is gradually reduced, and may be sent into further cooling coils at a still lower temperature and hence to a collection vessel wherein the sample will condense and be separated from the inert carrier gas. The second set of cooling coils may be cooled by an acetone-solid CO 2  mixture, and the inert carrier gas, after being separated from the sample, is directed up through the first cooling chamber, in countercurrent to the sample flow, to act as coolant. It may then be collected, cleaned, compressed and reused as carrier gas. For further control of the cooling gradient, the carrier gas plus sample may be heated, as it is cooled, by a heated body, e.g. electric resistance wire, disposed in or along the gas flow tube. This tube being surrounded by a cooling jacket.

Title: Improvements in the treatment of filaments, threads, fabrics, films, and like materials
IPC: D06P1/645
Filed: 1936-06-03
Abstract: The affinity of regenerated cellulose filaments, fibres, and films to cotton dyestuffs is increased, without introducing combined nitrogen into the cellulose, by subjecting the undyed materials to a swelling treatment with a water-soluble organic nitrogenous base in which each atom of carbon directly attached to nitrogen is also directly attached to three other atoms, or, when the nitrogen atom is doubly linked to said carbon atom, to two other atoms.  Suitable materials for treatment are saponified threads or fabrics of cellulose acetate or other ester, or materials produced by the viscose or cuprammonium process. Particularly useful are materials of high tenacity obtained by a stretching process.  A number of nitrogen bases are specified, and these may be applied in vapour or liquid form, or in solution in a non-hydroxy organic liquid, e.g. acetone, diacetone alcohol, dioxane or methylene ethylene ether, or non-hydrotropic liquid, e.g. benzene or chlorinated aliphatic hydrocarbon, or in an alcohol, e.g. methyl, ethyl, propyl isopropyl or benzyl alcohol, or preferably, in aqueous solution.  The treatment may be carried out with or without shrinkage or stretching of the materials. Specification 345,989 is referred to.  According to the Provisional Specification, the process is applied also to the treatment of cellulose of vegetable origin, and to the base there may be added small quantities of heavy metals, e.g. iron, cobalt, nickel, zinc or silver, or other swelling agents, e.g. thiocyanates, perchlorates, iodides, bromides, or nitrates.
