Patent GB-214960-A (GB)
Abstract: 214,960. Heise, R. April 28, 1923, [Convention date]. Vacuum engines.- To render the speed of the tune-sheet of an automatic musical instrument uniform and independent of variations in the load on the tunesheet mctor, an auxiliary governorbellows 9 is coupled to the usual governorbellows 2 arranged between the suction-chest 1 and the tempo-valve 7 leading to the tune-sheet motor at 8. An increased load on the motor causes increased air-tension therein, and the auxiliary bellows 9 then acts to reinforce the tension-spring 3 so as to increase the power of the motor. The coupling 11 may be adjustable.

Abstract: 918,288. Pneumatic separating. STURTEVANT MILL CO. June 20, 1960, No. 21589/60. Class 117. Granular material fed at 6 into a closed casing 2 is centrifuged by a rotating plate 10, and air is drawn upwardly through the cascading material by a fan 34 whereby the finer fraction is carried upwardly through a rotary sizing device 33 and passes downwardly to a section 4 from which it is removed via a rotary valve 28, and the coarser fraction falls down an inner casing 12 to an outlet 18 having a rotary outlet valve 20. The classifying air is drawn into the apparatus through a conduit 30 and is discharged from a conduit 38 having a valve 40 which controls the outflow and hence the classifying action.

Abstract: 403,168. Positioning shuttles in looms with automatic weftreplenishment. TERRY, P. J., 22, Slagg Street, Burnley. Aug. 2, 1932, No. 21601. [Class 142 (iii).] When the shaft g<1> is turned for changing the cop in the shuttle, it turns a shaft b through link and lever devices and a give-way spring d<3>. A finger h on the shaft b is thereby turned into the position shown in dotted lines in Fig. 4 and engages in the shuttle slot. A lever m has one end adapted to engage the picker k while the other is acted upon by a spring n<3> on a rod n connected to a lever on the shaft b. After weft-replenishment has been effected, a spring returns the shaft b to its normal position so that the finger h is clear of the picker and shuttle.

Abstract: 1,236,364. Aerials. OFFICE DE RADIODIFFUSION - TELEVISION FRANCAISE. 28 April, 1969 [30 April, 1968], No. 21601/69. Heading H4A. An aerial for use within the M.F. band (300 to 3000 kHz) comprises a vertical, grounded metal pylon 1, Fig. 3, which has a height of substantially a wavelength at the nominal frequency of operation and which, as described, is of lattice type and of triangular cross-section. Extending around the pylon is a skirt of conductive wires 2 which are suspended from outriggers 3, and which are kept taut by guided counterweights 5, one being provided for each pair near ground level. A rod insulator 9 is provided in each wire 2 at its mid-point, and another rod insulator 10 is provided above the counterweight 5. The wires are connected together every 15 metres by horizontal conductive wires girdling the skirt. Besides being connected to the pylon at its top, each wire is further connected to it at points which are, respectively, one-, two- and three-fourths of the pylons length from its top. At each said point an articulated linkage comprising a triangle 12, Fig. 7, is provided between a U-link 13 engaged on the wire 2, and beams 11 on the pylon 1. The linkages are bridged by conductive jumper wires to ensure electrical continuity. The aerial is supplied by a coaxial feeder 14, which runs up the inside of the pylon 1. The feeder comprises a central conductor (15), Fig. 4 (not shown), which is supported by insulators inside an outer sheath of conductors (16). As is shown in Fig. 3, the central conductor of the feeder 14 is connected to the skirt of wires 2 at a point in the upper half thereof, adjacent its centre, said point being selected to match the aerial and feeder impedances. The feeder is continued up the pylon, and a short-circuit CC1 acts as a means of adjusting reactance at the feed point. A short-circuit CC2 between the bottom-half skirt of wires 2 and the pylon provides compensation for the capacitance to earth of the end of the bottom half-skirt.

Filed: 1922-08-09
Abstract: 190,445. Augereau, A. J. Dec. 14, 1921, [Convention date]. Displacement, determining. -Apparatus for weighing a ship's cargo by consideration of displacement of the ship comprises a reservoir 2, Fig. 1, suspended by a rod 17 from one beam 18 of the weighing-mechanism and communicating with the water of notation by way of the flexible pipe 37, the reservoir being provided with T-pieces 34, Fig. 2, in communication with fixed T-pieces 36<a>, Fig. 1. The weighing- mechanism is supported on a knife-edge 22, Fig. 1, resting on a bearing 23 adjustable along a slide 24 pivoted at 26 in bearings 27 mounted on the deck. The pivot 26 also carries a pendulum 30 associated with a second :.ndex 31 which works across a scale 32. In the event of the ship having a fore and aft list, the bearing 23 is suitably adjusted along the slide 24 and the balance tilted about its pivot 26, after consideration of the reading of the pointer 31, until the vertical axis of the apparatus passes through the centre of buoyancy of the ship; the balance is then fixed in this position by means of a screw which tightens the pivot 26. In order to put the apparatus out of action when at sea, hollow rods 20 depending from the beam 19 act as guides for rods 39 connected by a cross-rod 40 with projection 42 which co-operates with a fixed rack 41<a>. The rods are raised by levers 42, Figs. 2 and 2<a>, associated with rods 44 and locking-members 45 which are raised to grip the reservoir by the operation of a screwed rod 48 carrying nuts 47 and levers 46. In the modification shown in Fig. 2, the pendulum 57 supported by a member 52 carried by the casing carrier a table 58 with suitable graduations which are read with reference to the pointer 59. The reading so determined is transferred to the graduated disc 60 supported on the pivot 63 and raised or lowered with reference to the weighing apparatus by the operation of the screw 61 on which it is mounted.

Title: Hydrogenation of polyallyl alcohol
IPC: C08F8/04
Filed: 1947-08-07
Abstract: Polyallyl-type alcohols are hydrogenated by subjecting them in neutral or alkaline solution and in the presence of a catalyst, to the action of hydrogen at a temperature of 100 DEG  to 207 DEG  C. and a pressure of 500 to 3000 pounds per square inch.  The solution in water or methyl, ethyl or isopropyl alcohol is neutralized or rendered alkaline by sodium or barium hydroxide or calcium oxide. The preferred catalyst is Raney nickel, whose particles may be electrostatically charged.  The process may be continuous.  In a modification, acidic polyallyl alcohol solution is refluxed over Raney nickel, the catalyst removed and fresh catalyst used for hydrogenation.  Polyallyl alcohol may be prepared by passing air into triallyl borate at 137 DEG  C. for 120 hours.  The polytriallyl borate formed is then hydrolysed, boric acid is filtered off and monomeric allyl alcohol distilled off.  Allyl-type alcohols specified are allyl, methallyl, ethallyl, chlorallyl, crotyl, tiglyl, cinnamyl, and 3-hydroxy-butene-1, 3-hydroxypentene-1, 3-hydroxy-hexene-1, 3-hydroxycyclopentene, 3 - hydroxy - cyclohexene, 3-hydroxy - 3 - methyl - butene - 1, 3 - hydroxy - 2 - methyl - butene - 1, 3 - hydroxy - 2,3 - di - methyl - butene - 1, 3 - hydroxy - 3 - methyl - pentene - 1, 3 - hydroxy - 2 - methyl - pentene - 1, 1-hydroxy-2-methyl-pentene-2, 1-hydroxy-2-methyl - hexene - 2, 1 - hydroxy - butadiene - 2,3, 3 - hydroxy - pentadiene - 1,4, 4 - hydroxy - 2,5 - dimethylhexadiene - 1,5, 1 - hydroxy - hexadiene - 2,4, 1 - hydroxy - hexadiene - 2,5, 2 - hydroxy - hexadiene - 3,5, 1 - hydroxy - 3,7 - dimethyloctadiene - 2,7, 3 - hydroxy - hexene - 1 - yne - 5, 3 - hydroxy - 2 - methyl - pentene - 1 - yne - 4, and 3 - chloro - butene - 2 - ol - 1.  The products may be mixed with solvents, swelling agents, plasticizers, tackifiers, dyes, pigments, fillers, oils, natural and synthetic resins, cellulose derivatives and protein plastics, and used as moulding, coating, impregnating and adhesive compositions.
