Title: Improvements in or relating to conical diaphragms for sound-reproducing and like devices
IPC: H04R7/12
Filed: 1927-12-08
Abstract: 307,450. Clifton, W. E. Dec. 8, 1927. Diaphragms : loud-speakers ; magnetic instruments.-A diaphragm of thin sheet-like material for sound reproducing and like devices, more particularly loud-speakers, is so formed that its surface conforms to that of a cone with the larger end polygonal, e.g. square, in plan. In the constructions shown, the diaphragm is formed from a flat blank 10 of cardboard, manilla board, stout paper &c. of the form shown in either Fig. 1 or Fig. 4, the margins 12, 13 on opposite sides of the gap 11 being overlapped and secured together by adhesive. Fig. 7 shows a construction of loud-speaker in which the diaphragm 10 is mounted on the diaphragm 114 of a unit 14 in the manner described in Specification 304,805. The unit 14 is mounted on a rail 15 extending across the back of a square casing 16, the open front of which is provided with an inwardly projecting flange 17. The diaphragm is mounted in the casing so that its centers are pressed against the flange 17 to which they are preferably secured by pins, adhesive &c. Pads 18 of felt &c. may be inserted as shown, if desired. Alternatively, lugs secured to the diaphragm may serve as the means for securing it in position. The sides of the casing 16 are brought so close to the edges of the diaphragm that they, in conjunction with the flange 17, serve to baffle the diaphragm. In a modification, Fig. 10, the diaphragm 10 is actuated by a coil 21 carried on the outer or inner surface of a former or spider 20 and located in the air gap of a magnet system 22. The inner end of the former fits snugly in the aperture in the smaller end of the diaphragm and abuts against a conical element 23, the diaphragm, former and elements 23 being secured together by adhesive. In -both constructions, Figs. 7 and 10, the flange 17 is preferably secured to the casing 16 by screws passing into the walls of the casing through elongated slots in the flange so that the latter can be adjusted relatively to the casing in a plane adjacent to and parallel with that of the open end of the casing. In the case of the moving coil instrument, this adjustment allows the coil to be adjusted to its optimum position in the magnetic air-gap.

Filed: 1961-10-16
Abstract: Polyurethane prepolymers are made by reacting an organic compound having at least two isocyanate reactive groups in the molecule with an organic polyiso(thio)cyanate without the application of external heat.  The polyiso(thio)cyanate is added in at least two portions; the addition being interrupted when the equivalent of between 1 and 2 iso(thio)cyanate groups has been added for each isocyanate reactive group of the organic compound, one or more further quantities of polyiso(thio)cyanate being added after the viscosity of the mixture has exceeded a value of 10,000 C.P. at 25 DEG  C.  The total quantity of polyiso(thio)cyanate added being sufficient to give a free iso(thio)cyanate content not less than 8% by weight in the final reaction mixture.  The organic compounds containing isocyanate-reactive groups which are specified are polyether polyols, polyesters, polyesteramides and glycerides of hydroxy acids. Polyurethane foams are made by mixing the prepolymer with a compound or compounds capable of inducing foaming and cross-linking and allowing the material to foam and set. Specified are water and catalysts such as tertiary amines and in the examples dimethylsiloxane polyoxyalkylene block copolymers are also added.

Regulation, automatic.-A frequency relay has a voltage coil 9 and a current coil 7 connected together at one end to form one terminal of the instrument, which is connected to one terminal of the supply 4. The current coil 7 is connected through a resonant circuit comprising an inductance 6 and condenser 5 to the other supply terminal. The voltage coil 9 is connected across the supply terminals in series with a condenser 10 or an inductance. Fine adjustment of the resonant circuit may be effected by an adjustable condenser 11 or inductance 12, or both. The main inductance 6 is preferably astatically wound. A variable resistance 13 permits adjustment of the sensitivity. The coils 7, 9 are shown applied to a moving-coil relay which makes one of two contacts 15, 16 according as the frequency is above or below normal. This relay may control switches 20, 21 which shortcircuit one or other of the field windings 22, 23 of a split-field governor motor 24 connected to direct-current mains 25. The motor 24 is thus caused to rotate in one direction or the other according as the frequency is above or below normal. In another arrangement, the relay controls a two-pole reversing-switch which reverses the armature connections. The invention may be used in conjunction with the rotating contact maker described in Specifications 241,523, [Class 38 (iii), Electric motor control systems &c. J, and 309,434.

Abstract: 1,070,245. Tractor power lift mechanisms. ZKL ZAVODY NA VALIVA LOZISKA A TRAKTORY NARODNI PODNIK. Aug. 24, 1964 [Sept. 28, 1963], No. 34479/64. Heading A1P. The main ram 41 and an auxiliary ram 63, Fig. 7 (not shown), in a tractor power lift mechanism can be operated simultaneously and independently of one another. A manual valve 4 controls the supply of fluid from a pump 1 through conduits 11, 12 to a distributing valve A from which the fluid passes through conduits 20, 22 and non-return valve 24 to the main ram 41, and through conduits 17, 18 and valve B to the auxiliary ram 63. The piston 8 of the valve A balances the pressures of the fluid supplied to the two rams. When the auxiliary ram is not in use, the slide 26 of the valve B is moved to cut off its supply and to open conduit 28 from which fluid flows via non-return valve 31 through a filter 44 to sump. This fluid can be diverted into the main ram, for quick operation thereof, through non-return valve 25 by pressuring the chamber 31<SP>1</SP> to close the valve 31. Operation of the slide valve 33 closes the exhaust conduit 57 and so diverts fluid from the conduit 35 into the chamber 31<SP>1</SP>. For weight transfer from the implement to the tractor the slide 16 of the valve C is moved so that the ram 41 communicates with the valve 46 via conduit 37 so that the ram pressure is kept constant. In the neutral position the piston 8 of the valve A opens a differential valve 13 through which fluid flows to exhaust via hole 58.
