Abstract: 1473003 Electric clocks BUNKER RAMO CORP 5 Aug 1974 [21 Aug 1973] 34452/74 Heading G3T In an electric clock, e.g. a car clock, having a housing (not shown) containing a motor 4 energized by a circuit on a board 9, a mounting plate 8 is used to attach the circuit board to the rear wall 11 of the motor, and electric terminals 10a, b project from the plate 8 through the housing to allow an external supply to be connected to the circuit board. As described the terminals are riveted to the plate and project through apertures 31, 32 in the board, pins 19, 20 connected to the terminals being soldered to the board circuitry, as also are motor leads 33, 34. Terminal 10a projects through the plate to provide a ground connection (10c), Fig. 4 (not shown) to the motor. The plate 8 is connected to the motor by engaging its apertures 14, 15 over lugs 12, 13 which are then deformed. Conical locating pins (27), Fig. 2 (not shown) project from the rear of the plate and engage bores 28, 29 in the board which is spaced from the plate by posts (24-26) on the latter. The posts have bores to receive screws which attach the housing and which also pass through the circuit board. A recess 30 in the plate accommodates some components on the board. The motor drives hands via gearing 3.

Title: Improvements in or relating to the production of thiophenes
IPC: C07D333/10
Filed: 1945-12-20
Abstract: Thiophenes are prepared by heating a sulphur oxide and an organic compound having a straight chain of at least four carbon atoms at a temperature of at least 700 DEG  F., in presence of an oxide or sulphide of a metal or metalloid, in the vapour phase, and at a space velocity of between 0.3 and 5.  Metalloid is defined as an element having the physical properties of a metal and the chemical properties of a non-metal, e.g. arsenic, antimony, silicon, and bismuth, boron being regarded as a metal. Catalysts specified are chromia, molydena, silica, alumina, vanadia, boria, titania, magnesia, and the sulphides of molybdenum, nickel, tungsten, cobalt, and tin.  The straight chain organic compound may be a saturated or unsaturated aliphatic hydrocarbon, or may contain aryl or halogen substituents. Sulphur dioxide or trioxide may be used.  In examples: sulphur dioxide and n-butane are heated in presence of (1) a freshly-prepared or a reactivated chromia-alumina catalyst; (2) a vanadia alumina catalyst; (3) a molybdenum sulphide-alumina catalyst; (4) an acid-treated, active clay as catalyst; (5) molybdena-alumina catalyst; (6) a dried silica gel.  Also in examples: (6) sulphur dioxide and n-pentane or isopentane are heated in presence of a freshly-prepared chromia-alumina catalyst. The temperatures range from 1000 DEG  to 1100 DEG  F. and the space velocities from .9 to 1.6.

Title: Improved means applicable to a rotating shaft for automatically stopping or reversing its motion
IPC: F16D43/00
Filed: 1927-12-21
Abstract: 313,978. Bailey, F., and Jackson, F. H. Dec. 21, 1927. Stop-gear.-In means for stopping and reversing a motor-driven shaft described as applied to a water strainer of the rotative and reversible type which upon becoming choked is reversed until the obstruction is again met when reversal again takes place, a flywheel w is frictionally mounted between collars upon a threaded sleeve e mouned upon a screwed shaft driven by an electric motor. The inertia of the flywheel carries the sleeve along the shaft when the motor is overloaded and effects through a lever r and switch mechanism controlled thereby the stoppage or reversal. The shaft t has flanges h and spring-pressed, axially-slidable buffer collars l at its ends. Ratchet projections l<1> on the collars engage like projections on the sleeve and arrest its travel upon the shaft. The lever r through gearing n, n<1> and lever r' actuate switch arms a, a<1> which are connected by a tension spring a<2> to return them to their off position. The lever r<1> carries a spring s which engages pivoted detents k on the arms a, a<1>. Magnets m, m<1> retain the arms in position. The arm r' is eccentrically arranged with respect to the arms a, a<1> so that the spring s can slip past the detents and avoid straining the parts. The switch arm returns to its central position upon an overload coil o coming into action.

Abstract: 1,159,963. Extruding foam particles with binder; laminated foam. IMPERIAL CHEMICAL INDUSTRIES Ltd. 29 July, 1966 [16 Aug., 1965], No. 34920/65. Headings B5A and B5N. [Also in Division C3] Fragments of polyurethane foam are wetted with phenol/formaldehyde mix which acts as a bonding agent, and which contains any necessary curing agent, and are compressed in a mould or by extrusion. The extrusion product is in the form of a board or block which may be faced by placing a material such as paper, plastic sheet, wood, asbestos, roofing felt &c. in contact with the resin as curing takes place. In the example, scrap polyurethane foam is fragmented by a rotary cutter, the crumbs then fall into a rotating barrel where they are tumbled and wetted by spraying with phenol/ formaldehyde resin mix. The wetted crumbs then pass through a rotating spiral and are extruded, between flexible facing material, and at the same time passed through a heating zone to cure the resin. The compression of the wetted fragments may be carried out in a mould.

Abstract: The invention comprises a bisphenol of the formula: <FORM:0952152/C2/1> in which R is a hydrogen or chlorine atom, an alkyl group having up to four carbon atoms or a phenyl group, R1 is a hydrogen or chlorine atom or an alkyl group having up to four carbons and X is 0 or 1.  The bisphenols in which X is 0 are made by heating hexachlorocyclopentadiene with an a ,b -unsaturated aldehyde RCH= CHCHO to give a Diels Alder adduct (hexachloronorbomene-2-carboxaldehyde) and this is condensed with a phenol in an acidic medium to yield the bisphenol. Hydrochloric, sulphuric, toluene-sulphonic or methionic acids can be used.  The bisphenols in which X is 1 are made by Diels-Alder reactions between cyclopentadiene and an a ,b -unsaturated aldehyde and then between the adduct so obtained (norbomenecarboxaldehyde) and hexachlorocyclopentadiene forming a second adduct (a hexachloro-octahydrodimethanonaphthalene-2-carboxaldehyde) which is condensed with a phenol to form the desired bisphenol. Specification 794,621 is referred to.ALSO:The invention comprises a linear polycarbonate containing recurring units of the formula: <FORM:0952152/C3/1> in which X is 0 or 1, R is a hydrogen or chlorine atom, an alkyl group containing up to four carbon atoms or a phenyl group, and R1 is a hydrogen or chlorine atom or an alkyl group containing up to four carbon atoms. The linear polycarbonates may also contain other units recurring in ordered or random arrangement. The polycarbonates may be made by condensing one or more disphenols of the formula: <FORM:0952152/C3/2> with phosgene or bischloroformates of aliphatic, cycloaliphatic or aromatic diols. Mixed copoly-carbonates may be made by using a mixture of bisphenols some of which do not have the above formula. The linear polycarbonates may be made into films and shaped articles.

Title: Improvements in or relating to methods of separating mixed fatty acids
IPC: C11C1/00
Filed: 1946-11-27
Abstract: In the separation of mixed fatty acids obtained from animal fat by solution in a solvent miscible with water and chilling, the water content of the solvent does not exceed about 15 per cent by weight thereof and the concentration of the mixed fatty acids in the solvent does not exceed about 30 per cent by weight of the solvent solution, the solution being chilled to a temperature sufficient to cause precipitation of crystals mainly of stearic and palmitic acid and the fatty acids remaining in the solvent being then recovered therefrom. The solution may be chilled in steps to obtain a first fraction richer in stearic acid and later fractions richer in palmitic acid, three steps being preferred and the intermediate step giving a eutectic mixture of stearic and palmitic acids.  The fatty acid recovered from the solvent after the precipitations is usually oleic acid, also known as red oil. Water miscible polar solvents are preferred and methyl alcohol, ethyl alcohol, isopropyl alcohol and acetone are specified.  The crystalline precipitates are preferably washed with the solvent maintained at a temperature of about that at which the crystals precipitated from the solution.  The process may be applied to commercial stearic acid which is a mixture of stearic and palmitic acids.
