Patent GB-803466-A (GB)
Title: Improvements in or relating to typographical line-composing and casting machines
IPC: B41B11/06
Filed: 1956-01-25
Abstract: 803,466. Type-bar-making machines. LINOTYPE, G. m. b. H. Jan. 25, 1956 [Feb. 8, 1955], No. 2510/56. Class 100(3) Magazines. In a device for changing over magazines in typographical line-composing and casting machines, the power for shifting the magazine is supplied by an electromagnetic system with an armature mounted for reciprocating motion, which system is actuated by hand or by means of a relay controlled by a perforated strip. On energization of a solenoid 1 by means of a manual key 4 or a relay actuated by the perforated tape, a push rod 8 is raised and co-operates with a cam slot 10 to rotate clockwise through about a right-angle a cam plate 11 fast on a shaft 12. The shaft 12 carries cams 15, 18, which respectively lift the escapement bars 21 and shift the magazine frame 19. The solenoid is soon de-energized as by release of the key, and the rod 8 returns by gravity, its pin 9 moving to the now lower end 14 of the slot 10. A subsequent energization of the solenoid will thus cause counter-clockwise rotation of the shaft 12 and shifting of the frame 19 in the opposite direction. Alternatively, where other parts such as escapement bars do hot require displacement, the member transmitting the mechanical power from the electro-magnetic system (e.g. the plunger 6) may act directly on the magazine frame using an electromagnet acting mechanically in both directions, a solenoid energized in one working position and deenergized in the other, or a self-locking solenoid mechanically locked in the working position and de-energized.

Title: Improvements in or relating to Telephone Installations, particularly for Wireless Telegraphy.
Inventor: BRILLOUIN LEON NICOLAS
IPC: H04B1/22
Filed: 1917-02-22
Abstract: 127,014. Brillouin, L. N., and Beauvais, G. A. Nov. 7, 1916, [Convention date]. Telephonic relays.- In telephone receiving- apparatus, particularly applicable to wireless telegraphy, of the kind in which the incoming telephone currents, or high-frequency oscillations, are amplified by a, number of threeelectrode thermionic valves acting in succession, the plate electrode of each valve is connected through a resistance to one pole of the battery supplying the filament-plate circuits, and a con. denser is interposed between each plate and the grid of the next valve. When the apparatus is used merely as an amplifier, the normal grid potential is made negative relatively to the whole of the filament; but when, in the absence of a separate detector, the valves are required to act also as rectifiers, the normal grid potential is positive. Reactive connexions made be made from the plate of one valve to the plates or grids of preceding valves, and these may be adjusted so as to assist or reduce the amplification, or to set up local oscillations for heterodyne working. As shown in Fig. 1, the filaments a<10>, a<20>, a<30> of the valves a', a<2>, a<3> are heated by a battery b. The grid filament circuit of each valve includes a resistance h<1>, h<2>, h.<3> and a potentiometer j which determines the normal grid potential. The plate filament circuit of each valve includes a resistance d<1>, d<2>, and a battery c with its negative pole connected to the positive pole nf the heating-battery b. The incoming telephone currents or oscillations are conveyed to the grid a<100> of the first valve, preferably through a condenser f<1>, and a connexion is made through condensers f<2>, f<3>, &c. between each plate a'‹‹‹ and the succeeding grid a<200>. The plate-filament circuit of the last valve includes a telephone receiver g. In addition, the plate of one or more of the valves may be connected, through a condenser or resistance or both, to the grid or plate of one of the preceding valves, or these connexions may be made between adjustable points on the resistances d<1>, d<2>, &c. In the arrangement shown in Fig. 6, the incoming terminal e<2> is connected to a condenser plate q<3> which can be swung into capacitative relation with.either of the fixed plates q', q<2>, connected respectively through resistances r<1>, r<2> to variable points on the resistances d<1>, d<2>. By adjustment of the plate q<3>, the apparatus may be regulated so as to give strong amplification of damped oscillations, or to act as a source of oscillations interfering with received continuous oscillations. The resistances are preferably made of short wires of high resistivity, or by a thin deposit of metal on an insulating support or carbon. The connexion wires are made as short as possible, and all metal parts of the apparatus not acting electrically are connected together.

Abstract: 700,768. Gas turbine plant. BRISTOL AEROPLANE CO., Ltd. Jan. 29, 1952 [Feb. 5, 1951 ; May 4, 1951 ], Nos. 2841/51 and 10582/51. Class 110 (3) [Also in Group XXIV] A coupling, especially for coupling a gas turbine shaft 28 to a compressor shaft 24 and permitting slight misalignment thereof, comprises interengaging teeth 50 on members 47, 49 fixed to the shaft ends. A sleeve 30 with spherical convex surfaces 36 fixed to a spigot 29 on the shaft 24 engages a sleeve 33 with spherical concave surfaces 37 fixed within the end of the shaft 28. The sleeves 30, 33 are engaged by a relative axial movement followed by a relative rotary movement. Such rotary movement is transmitted to the sleeve 33 by a tubular member 40 splined at one end 39 to an extension 38 of the member 33 and having at the other end a flange 41 with lugs 42 engaging notches 43. in the end of the shaft 28. When the lues 42 and notches 43 are engaged the spherical members 30, 33 are locked together. To free the members 30, 33 the turbine discs 27 and an end cap 44 on the end of the shaft 28 are removed, the lugs 42 are displaced axiallv from the notches 43 and the tubular member 40 is turned by engaging the lugs 42 with a suitable tool. To ensure correct assembly of the coup.... members 47, 49, some of the interengaging coupling teeth 51 differ in size from the remaining teeth 50 so that the coupling members are engageable in only one position. The fixing splines between the members 47, 49, 38 and the members 24, 28, 38, respectively, may be similarly arranged. Instead of releasing the coupling from the end of the turbine shaft, as shown, it may be released from the end of the compressor shaft. The invention may be applied to a gas turbine engine having high and low pressure compressors and high and low pressure turbines. The high pressure compressor and turbine shafts are interconnected by teeth similar to the teeth 50 and surround the tubular low pressure compressor and turbine shafts which are similarly connected and carry the spherically jointed members. Means are provided for detaching the various parts of the engine to facilitate uncoupling of the shafts.

Title: Improvements in or relating to method of preparing phenol-aldehyde composition and the composition resulting from said method
IPC: C09J161/06
Filed: 1955-02-02
Abstract: In obtaining adhesive thixotropic compositions of alkaline condensed phenol-formaldehyde or phenol-furfural-aldehyde condensates and an extender consisting of a dilute alkaline solution of a lignocellulose or a lignin produced in the acid hydrolysis of vegetable matter, the condensate is added in three portions, the first portion being added to the extender with dilute sodium hydroxide to swell the extender, the second addition terminating the swelling of the lignin, and the third portion being added together with a filler in such proportions to bring the total solids content of the compositions to 43-51 per cent; the ratio of said extender to said resin content is between 0.3 : 1 and 0.45 : 1, and the ratio of alkali added to resin content being of ratio 0.1 : 1 to 0.3 : 1.  The preferred filler is the ground lignocellulose residue produced in the manufacture of furfural but one of the usual cellulosic fillers, e.g. wood flour, walnut flour, may be used.  An accelerator is preferably added, e.g. alkali metal carbonate silicates, borates or phosphates, and an antifoaming agent, e.g. a dispersed mixture of an alkaline earth silicate, pine oil and petroleum distillate.  The phenol aldehyde condensate used is prepared as described in Specification 769,912 and has a solids content of 43-47 per cent.  An inter-condensed phenol-furfural-formaldehyde condensate was mixed with 24 parts of 50 per cent NaOH in 110 parts water.  The mixture was stirred and 90 parts ground lignin residue from the Madison Sugar process added; the mixture was stirred to swell the lignin and then a further 30 parts of condensate were added to terminate the swelling.  30 Parts of a filler consisting of 50 per cent NaCO3 and 50 per cent lignocellulose were added and finally a third portion of condensate.  After stirring a dark brown mixture having a viscosity of 120 centiposes at 25 DEG C. was obtained.  The above resin was prepared by (1) reacting 77.47 parts phenol and 17.76 parts furfural in presence of 2.79 parts 50 per cent NaOH and 1.98 parts water; (2) reacting 30.33 parts of the condensate obtained with 45.44 parts 37 per cent uninhibited formaldehyde in presence of 12.63 parts 50 per cent NaOH and 11.49 parts water.
