Title: Improvements in tensioning apparatus for the spindle drives in spinning and yarn twisting machines
IPC: D01H1/241
Filed: 1936-12-15
Abstract: 475,226. Tensioning-arrangements for belt gearing for spinning &c. machines. SATO, S. Dec. 15, 1936, No. 34461. [Class 80 (i)] [Also in Group IX] The tension of a tape for spinning and yarn twisting machines is maintained constant regardless of its expansion or contraction by a pulley 1, Fig. 1, supported on a pivot O by an arm 4 weighted at 9 in such manner that the centre of gravity of the apparatus is at C, Fig. 7, i.e. on a line OO<2> through O perpendicular to OO<1>, where O<1> is the centre of the pulley 1. To enable the tension to be adjusted, the weight 9 is supported by a screw 10 in a slot 16 in the cradle 8 supporting the arm 4, notches 17<1> being provided to engage a rib 17 on the weight. The weight is thus guided so that its centre of gravity moves along a line XY parallel to OO<2>, and the centre of gravity of the whole tensioner moves along the line OO<2>. The arm 4 may be rotated in its socket in the cradle 8 to suit the direction of the tape. The pulley holder 3 may be adjusted about a horizontal axis, a tooth 19 thereon, Fig. 5, being adapted to engage teeth 20, 20<1> on the arm 4, Fig. 6. In a modification (not shown), the weight 9 slides on a horizontal arm on the cradle 8. In a further modification, a ring depending from the cradle embraces a cylindrical weight whose axis is shiftable along a line parallel to OO<2>. In these modifications an indicator for the position of the weight is provided.

Title: Substituted phenethylamines
IPC: C07C233/02
Filed: 1962-09-10
Abstract: The invention comprises compounds of the formula (I) <FORM:0985340/C2/1> wherein R1 and R2 are normal or branched alkyl groups having from 1 to 5 carbon atoms, R1 and R2 not being able to be methyl groups simultaneously, and R3 is hydrogen or a methyl group, and their non-toxic salts.  The novel compounds are made by the following steps: carbinols of the formula (II) <FORM:0985340/C2/2> are made by reacting p-chlorobenzylmagnesium chloride in ethyl ether with a ketone of the formula R1-CO-R2 at a temperature ranging from room temperature to the mixture boiling point and recovering the product through water decomposition, solvent evaporation and distillation; the carbinol is reacted with hydrocyanic acid in glacial acetic acid and concentrated sulphuric acid at a controlled temperature, to form an N-formyl derivative of the formula (III) <FORM:0985340/C2/3> the N-formyl derivative is acid hydrolysed in a water-alcohol medium at the boiling temperature of the medium itself and the desired p-chlorophenethylamine is recovered by alkalization of the hydrolysis mixture, solvent extraction and vacuum distillation; the compounds of formula (I) in which R3=CH3 being obtained from compounds of the formula (III) through reduction with aluminium-lithium hydride, decomposition of the mixture with water, solvent extraction and vacuum distillation.  The intermediate carbinols and N-formyl derivatives are also novel compounds. Detailed examples are given.  The above novel compounds are useful in therapeutic applications as hypotensive agents, anti-spasmodic agents, sedatives, analeptic, anorexic and anticarcinogenic agents and may be administered, mixed with a suitable carrier, to form tablets, capsules or syrups, suppositories, or may be parenterally administered dissolved in a suitable solvent.

Title: Improvements in or relating to laminated vibration-absorbing materials
IPC: F16F1/366
Filed: 1960-10-11
Abstract: 937,172. Laminates. J. M. STEVENS. Oct. 11, 1960, No. 34761/60. Class 140. A vibration-absorbing material comprises a unitary structure composed of a plurality of layers of non-heat-activatable fibres bonded together and permeated with a non-fibrous fused plastisol mixture of vinyl resin and plasticizer, the weight proportions of resin and plasticizer being different in at least two adjacent layers to provide a structure having strata of different resonant frequencies of vibration. The weight ratio of fibre to resin may also differ between layers. As shown, a paste 1 of polyvinyl chloride and plasticizer with stabilizers and colorants if desired, is spread over two metal plates 3 with partspherical protuberances 5 on them. Mats 7 of fibre-glass are dry, unsized and unimpregnated and may be woven, needled on to a woven fibre-glass scrim, or with their fibres merely assembled in bat form. One is laid lightly on each paste layer 1. Layers 9 of sisal, jute, fibre-glass or other fibre are unimpregnated and may be in the form of a bat of random fibres or a needled bat with or without a woven backing. Two of them are sized by roller or spray on one side only with a thin layer 11 of polyvinyl chloride paste containing a gasgenerating substance, e.g. ammonium bicarbonate, ammonium carbonate or water. Two such layers are placed between the two mats 7 to make the assembly shown. This is placed in a press having heated platens 13 held apart by spacers 17, 19 and 21. Heat is applied for a sufficient time to gel the layers 1, while the mats 7 act as barriers and heat insulators to prevent intermingling of the paste layers, or flow of heat inwards. The spacers 17 are then removed and the press closed, so that the fibreglass of layers 7 is forced into the soft sheets 1, and heat passes to the centre layers 9. This activates the gas-generating substance, and the gas pressure forces the layers 11 into the layers 9 and disperses their material uniformly therethrough. When the gelation of the material 11 is complete, the spacers 19 are removed and the press again tightened to compress the body to its final thickness. Instead of polyvinyl chloride, one may use a copolymer of vinyl chloride and vinyl acetate or vinyl maleate.

Abstract: 1376735 Fire-operated doors and windows TELEFLEX Ltd 18 July 1972 [23 July 1971] 34794/71 Heading A5A [Also in Divisions F2 and G1] A temperature sensitive actuator 16 for automaticaly operating a door or window installation 11 in the event of a fire comprises two rotary members 24, 25 (Fig. 3) separated by an energy storage spring 28 and an epicyclic year train, the rotary members 24, 25 and spring 28 being assembled to be rotatable conjointly except in the event of a fire when the rotary members 24, 25 are caused to rotate relative to one another by the action of the spring 28. As shown, the actuator 16 is inserted in a drive cable 10, 17 to a window installation 11 from a manually operable window opening and closing mechanism 12 in such a way as to provide a direct drive between the mechanism 12 and installation 11 except in the event of a fire when the actuator 16 automatically causes the window to close. The cable lengths 10, 17 which each comprise a relatively movable core and casing are connected respectively to an input wheel 24 and output wheel 25 of the actuator 16, the input wheel 24 being integral with a gear ring 27 which meshes with planet gears 31 carried by the output wheel 25. A spiral spring 28 which is fixed to the wheel 24 at its outer end is attached at its inner end to a spindle 29 which supports a sun wheel 30 meshing with the gears 31. The spindle is so connected by fusible plugs 34 to a tube 33 carrying the output wheel 25 that under normal temperature conditions the wheels 24, 25 are rotatable conjointly and maintain the spring in an energy stored condition. When, however, the plugs 34 fuse upon being subjected to an elevated temperature either directly by the action of a fire or by a heater 36 operatively connected to a smoke detector, the spring 28 releases its stored energy to cause the wheel 25 to rotate relative to the input wheel 24 and thereby close the windows 11.

A fluid pressure governor comprises a body 10, 11 having an inlet connection 1 separated from an outlet connection 6 by a valve seat 2, a closure member 3 adapted to engage the seat 2 secured to a radially intermediate region of a annular flexible diaphragm 8 of which both the inner and outer peripheries are clamped in the body, one side of the diaphragm (the upper side in Fig. 1) being exposed to atmospheric pressure and the other side being exposed to fluid pressure in the outlet 6, the arrangement being such that the pressure in the outlet acts on the diaphragm to urge the closure member into engagement with the seat. The weight of the closure member acts in opposition to the closing force and the weight of the member 3 may be augmented by further weights or a spring. In a further embodiment the inlet and outlet connections lie on the same side of the valve seat and are normal to its axis. In another embodiment the closure member is formed by an upstanding flange on a dished-shaped member 4.

Abstract: 177,586. Arrol & Co., Ltd., Sir W., and Huntley, J. H. Dec. 22, 1920. Jib cranes.-A jib in the form of a two-armed lever pivoted at a<4> is luffed by a force applied to the short arm or tail at a point that varies with the position of the jib. Means are provided such that the load travels horizontally or in some other predetermined path as the jib is raised, the dead-weight of the jib is approximately balanced in all positions, continued movement of the luffing mechanism moves the jib to and fro between determined limits, and luffing is effected without the use of ropes or chains. The tail of the jib forms a runway a<2> for two trollies b, c. The balancing trolley c carries a counterweight and is moved along the tail of the jib by the luffing-link m, which is pivoted to the frame at a point m<1> below and to the rear of its point of attachment m<2> to the trolley. The link m is raised and lowered successively by continued rotation of a crank k. The compensating trolley b is controlled by rollers d which run in guides e in the framework of the crane. The load rope g runs from the hoisting-drum h over sheaves i, b<1>, i<1>, b<2>, to the head sheave, the sheaves b<1>, b<2> being mounted on the trolley b. As the jib is raised from the position shown, the sheaves b<1>, b<2> approach the fixed sheaves i, i<1>, shortening the loop g<1> and paying out the load rope at the jib head, to an extent determined by the contour of the guides e.
