Abstract: 1,091,164. Sewing machines. INDUSTRIAL RESEARCH & DEVELOPMENTS Ltd. Oct. 21, 1966 [July 23, 1965], No. 31391/65. Heading DIG. A thread tensioner in or for a sewing machine comprises means capable in one state of restraining the thread and in another state of permitting free passage of the thread, means for causing the restraining means to alternate periodically between its two states, and gravityloaded means for applying controlled tension to the thread when the latter is restrained. A block 10 is formed with a vertical bore 11 having an open upper end and a restricted lower end communicating with a horizontal bore 12. A weight 13, slidable in bore 11, carries a pulley 15. Two coaxial pulleys 16, positioned above bore 11, are carried by a fixed block 18. A cylindrical bar 20. vertically slidable on a pin 22, is biased by a spring 21 against a flat bar 19 positioned adjacent the upper end of bore 11.

Thread 24, from a supply spool passes over cam 29 between eyes 32, 23, and after passing between bars 19, 20 and then being wound about pulleys 15, 16 to support weight 13, passes to the needle. In operation. when lobe 31 engages the thread, bar 20 engages bar 19 to restrain the thread and weight 13 applies controlled tension thereto, while lobe 31 draws off thread from the supply. When lobe 31 engages arm 28, arm 25 raises bar 20 to free the thread from restraint and weight 13 advances the previously drawn off thread. Compressed air is supplied to bore 12 for facilitating the movements of weight 13. A plurality of bores 11 may be provided for use with a multi-needle machine.

Title: Improvements in and relating to underfeed stokers
IPC: F23K3/10
Filed: 1941-03-22
Abstract: 546,896. Mechanical stokers. QUEENSMERE PROPERTIES & INVESTMENTS, Ltd., and CROOK, C. March 22, 1941, No. 3555/42. Divided out of 545,167, [Group XXVI]. [Class 78 (i)] In a mechanical stoker the conveyer for feeding the solid fuel, is driven from a reversible engine or motor through a transmission gear, the ratio of which is automatically altered on reversal of the motor, so that the rate of supply of the fuel is altered. The fan for supplying the air for combustion may also be driven from the - same engine or motor. In the construction shown a reversible electric motor E drives a shaft D through belt or chain gearing G, and the shaft D drives (1) the fan-shaft D<SP>1</SP> directly, and (2) the shaft S of a screw conveyer W through worm gearing K and eccentric and ratchet gearing L, P. The worm-wheel K carries an inner eccentric R fixed thereto, and an outer eccentric Q is rotatable on the inner eccentric through 180 degrees, a pinU on the outer eccentric engaging a semi-circular slot V in the worm-wheel. The outer eccentric is engaged by a strap O on an arm L which rocks an arm M carrying a pawl P engaging a ratchet wheel N fixed to the conveyer shaft S. Thus, when the worm-wheel K is rotated counter-clockwise, the left-hand end of the slot V drives the pin U so that both eccentrics remain in the relative position shown in which the throw of the combined eccentrics equals gr plus r t, whereas when the worm-wheel is rotated clockwise the pin U is driven by the other end of the slot V, the outer eccentric rotates on the inner one, and the throw of the eccentrics is reduced to q, r-r t, thus reducing the supply of fuel to the retort R. The fan, which is driven by the shaft D\ is preferably of the kind described in Specification 545,167 in which the fan delivers air when driven in either direction but delivers less in one direction than in the other.

Title: Improvements in the production of unsaturated alcohols from epoxides
IPC: C10L1/18
Filed: 1960-02-02
Abstract: a ,b -unsaturated alcohols are obtained by the catalytic isomerisation of epoxides having at least one hydrogen atom attached to a carbon atom adjacent to the epoxy group using an organo-aluminium compound as catalyst.  Suitable epoxides for use as starting materials are, for example, those with the structure <FORM:0877138/IV (b)/1> in which R1 to R5 each represents hydrogen or an alkyl, aryl, aralkyl, cycloalkyl or alkenyl group and n is a whole number, e.g. propylene oxide, 1.2-epoxybutane, 2.3-epoxybutane, 1.2-epoxyoctane, cyclohexene oxide, 1.2-epoxycyclodecane, and 1.2-epoxy-3-phenylpropane.  In addition the -(CH2)npart of the ring may be unsaturated, e.g. 1.2-epoxycyclododecadiene-5.9, or interrupted by hetero atoms. The process is also applicable to di- and triepoxides, e.g. diepoxycyclododecene.  Suitable catalysts are, for example, aluminium triethyl, diethyl aluminium hydride and di-isobutyl aluminium hydride.  The process is preferably carried out by dripping the organo-aluminium compound or its solution in an inert solvent into the epoxide at temperatures between 0 DEG  and 200 DEG C. Examples are given of the conversion of epoxycyclododecadiene-(5.9) to 1-hydroxy-cyclododecatriene-(2.5.9), and epoxycyclododecane to 1-hydroxycyclododecene(2).  Specification 877,139 is referred to.

In a method of pressure casting upwardly from a container 10 in a pressure chamber 2 the container and the mould cavity are both exhausted to equal subatmospheric pressures, and the chamber is then subjected to superatmospheric pressure until the mould 20 is filled. The mould includes a perforated hot top 21 with a sand lining 30 and an inner central projection 27 and is evacuated by means of a vacuum bell 34 connected by a pipe 36 to a vacuum source 48 which is also connected to the chamber 2 via a pipe 40 so that steel in the container 10 may be degasified. A source of pressure air or non-oxidizing gas 44 is also connected to the pipe 40. The pressures in the bell 34 and the chamber 2 may be equalised by opening a valve 51 in a pipe 49 connecting them. When the melt fills the hot top, contact with an electrode 50 causes the mould to be moved transversely on its seat 18 to close the gate 54.
