Title: Improvements relating to Gramophones.
Inventor: MCEWEN JOHN BLACKWOOD
IPC: G11B3/00
Filed: 1917-10-24
Abstract: 119,919. McEwen, J. B. Oct. 24, 1917. Tone - arm joints. - The sound-box is pivotally mounted on a telescopic extension tube of the tone-arm and is constrained by a jointed link and suitable stops, in such manner that, when the sound-box is swung round on changing from lateral-cut to vertical-cut records, the distance between the stylus and the tone-arm pivot remains the same. The sound-box 4 has a curved neck 41, the axis 5 of its outlet being parallel to the stylus bar. The neck 41 has a swivelling connexion to a downwardly-bent tube 3 which telescopes into the tone-arm 1, being guided by a pin 16 and longitudinal slot 17. At the rim of the sound-box outlet is mounted a pin 9 connected by a hinged link 8 to the pin 16. As shown in Fig. 1, the sound-box is in position for playing vertical-cut records. In order to play lateral-cut records, the sound-box is swung through approximately a right-angle around the axis 5. The pin 9 acting as a crank-pin causes the tube 3 to be drawn out from the tone-arm 1, thus placing the stylus at the correct distance from the vertical tone-arm pivot. At the same time the tone-arm is raised slightly on its horizontal pivot 14. A pin-and-slot joint 20, 21 between the parts 1, 11 of the tonearm allows the sound-box to be turned up for changing the needle, &c. The two positions of the sound-box may be determined by the limits of the slot 17, or other stops may be provided. The neck 4 may be locked to the tube 3 by a clamping-screw 18.

Title: An improved process for the production of vinyl chloride
IPC: C07C17/08
Filed: 1951-07-02
Abstract: In the manufacture of vinyl chloride by passing a mixture of acetylene and hydrochloric acid gas over a mercuric chloride catalyst the process is improved by passing the reaction mixture over a nickel chloride catalyst before passing it over the mercuric chloride catalyst.  Preferably the reaction mixture is passed over the nickel chloride catalyst at a temperature in the range 110-160 DEG  C. and at a volumetric rate from 5 to 8 times higher than the volumetric rate at which it is passed over the mercuric chloride catalyst.  The nickel chloride catalyst may be prepared by impregnating a porous support with a solution of nickel chloride and evaporating the excess water.  In the example a mixture of acetylic and hydrochloric acid with traces of chlorine was passed first over a nickel chloride catalyst and then over mercuric chloride to give vinyl chloride.

Patent GB-515353-A (GB)
Title: Apparatus for synchronising reciprocating engines
IPC: F02D25/02
Filed: 1938-05-27
Abstract: 515,353. Synchronizing engines. DEUTSCHE SCHIFF-UND MACHINENBAU AKT.-GES. May 27, 1938, No. 15913. Convention date, May 27, 1937. [Class 57] In apparatus for synchronising internal-combustion reciprocating engines which are not positively coupled or geared together, the fuel control mechanisms of the engines are coupled together by a synchronizing apparatus which from one engine, through one or more adjustable regulating devices which enable the relative crank positions of the engines to be varied during operation, effects regulation of the fuel supply of the remaining engine or engines in correspondence with the speed of the first engine. The regulating shafts 9, 10 of the fuel pumps 7, 8 of a pair of engines 1, 2 are operated by rods 5, 6 with hand controls 3, 4 which may be coupled by a shaft 11 with a clutch 12, and during hand operation arms 32a fast on the shafts 9, 10 are engaged by the lower ends of slots 39 carried by the rods 5, 6. The rod 6 is divided into two parts. The two cam shafts 17, 18 drive the shafts 21a, 21b, and 22 of a differential gear 24, 25, a reversing gear 23 also being provided. If the engines are out of synchronism the casing 25 rotates and, through a speed-reducing gear 26, 27 and the phase adjusting device 28, 29, 30, moves a synchronising cam disc 31. The wheel 29 and disc 31 are loose upon the shaft 22, and different phase relationships can be obtained by moving a pin coupling the wheels 27, 28 along a curved slot in the wheel 27 by means of hand control 30. The disc 31 actuates a roller-ended rod 31a connected with a spring or weight-loaded arm 32b which can be coupled with the shaft 10 by means of a friction clutch comprising a casing 33 which is loose upon, but can be coupled to, the shaft 10 by sliding in a hub 43, Fig. 3, by means of a lever 38, screwed spindle 44, and bevel gears 37. The latter are rotated by the control wheel 34 for engaging the synchronising apparatus through a toothed pinion 35 which engages a toothed wheel 36 having a threaded sleeve by which the ends of the divided rod 6 are drawn together. The wheel 34 is rotated manuallv or by power under manual control. For synchronising the two engines when they are running at approximately the same speed, the two controls are uncoupled by the clutch 12, and the engine 2 is adjusted by the' regulator 4 so that the two shafts 21b, 22 run as nearly as possible at the same speed and in the desired phase relationship. This is indicated by the cam disc 31 coming to rest in the predetermined correct position. The synchronising apparatus is then brought into operation by the hand wheel 34. This reduces the length of the rod 6 and frees it from the slot 39, at the same time bring- ing the shaft 10 under the influence of the cam shaft 17. Should the two engines go out of phase, the different speeds of the shafts 21b, 22 cause rotation of the disc 31, and thereby regulation of the quantity of fuel supplied to the engine 2. Mechanical transmission from the disc 31 to the fuel pumps may be replaced by pneumatic or hydraulic means.

Title: Improvements in and relating to the manufacture of glass and similar mineral fibres
IPC: D04H3/03
Filed: 1956-05-24
Abstract: 808,988. Bonded fibrous fabric. OWENSCORNING FIBERGLAS CORPORATION. May 24, 1956 [May 25, 1955], No. 16138/56. Class 140. [Also in Groups IX and XII] In making mats of mineral, e.g. glass, fibres consolidated by a binder, heat-softened material is centrifugally shaped into elongated bodies which are projected and attenuated by an annular gaseous blast to form a hollow beam of fine fibres to which the binder is applied and transverse forces act alternately from opposite sides to oscillate the fibres transversely to the direction of travel of the beam and distribute them over a collecting surface. In the apparatus shown in Figs. 1 and 3, a stream 20 of molten glass &c. discharged from a feeder 14 flows through a rotating shaft 30, falls on a plate 44 in a rotor 35 and is projected centrifugally against a wall 46 and through openings 48 thereof in the form of primary filaments 50 which are attenuated by a blast of gas, which is at a temperature exceeding the softening temperature of the glass &c., to form fine fibres 68 which descend in a spiral path as a hollow beam 70. A burner 55 is lined with refractory material 56 to form one or more chambers 57 wherein a mixture of fuel gas, e.g. methane, propane, butane, and air, supplied through pipes 60, burns completely and the gases of combustion are discharged at high velocity through an annular orifice or arcuate orifices 64 to soften further and attenuate the filaments 50. The beam 70 enters a hood 74 wherein gaseous streams are directed by means of a rotary valve mechanism 100 from nozzles 93 and 94 to impinge alternately against opposite sides of the beam which is oscillated thereby transversely of and is deposited on a collecting surface 78 of an endless foraminous conveyer 80. A binder 124 is applied by spraying through nozzles 125. The fibre collection is assisted and the spent gases removed by means of a suction chamber 84. A layer 130 of fibre is compressed by rollers 134 carried on arms 133 on a rotating shaft 132 and is then formed by a roll 135 (which may also apply size) into a mat which is conveyed through an oven 137 wherein the binder is used or set. Two separatelyformed beams descending into a hood may be urged simultaneously into corresponding transverse oscillation by gas streams directed alternately against opposite sides of both beams from pairs of nozzles at the sides and centre of the hood, Fig. 8 (not shown) and deposited in stepped overlapping folds alternatively or additionally, three or more separately-formed beams extending in series longitudinally of the collecting surface are alternately oscillated transversely thereof each by gas streams issuing from nozzles at the sides of the hood and impinging on opposite sides of the beams, Fig. 9 (not shown). Different forms of deposited mat, e.g. of uniform thickness or having linear zones of different thickness, result from variation of the timing or phasing, frequency and amplitude of the oscillations of the beam(s).
