Title: Plate having apertures for the passage of the roving at the outlet of fly-frames
IPC: D01H13/12
Filed: 1964-08-10
Abstract: In a fly frame wherein the rovings running to the flyers pass through apertures 81a, 81b (Fig. 6 not shown) in a plate 14, the apertures are provided with gripping means, such as triangular shaped slots 81a, 81b, at the points at which a broken roving would contact the aperture edge under the action of the air current created by the rotating flyers.

Abstract: 1,245,642. Magnetic recording disc. INTERNATIONAL COMPUTERS Ltd. 16 June, 1969 [9 July, 1968], No. 32713/68. Heading B5N. [Also in Division H1] In a process for making a double-sided magnetic recording disc, a glass plate 1 (Fig. 2) coated with cobalt 3 and thermosetting resin 7 is placed on ring 8, under split mould ring 9. Woven glass fibre re-inforcing layers 11, 13 and glass core plate 12 are assembled inside ring 9, while applying liquid resin to the interior of ring 9. A second cobalt/resin-coated glass plate 11, 3<SP>1</SP>, 71 is inverted over layer 13, and assembly completed by screwing down a second ring 14. Downward pressure of ring 11 pressed the component layers into intimate contact, causing excess resin to exude into peripheral space 10 in mould ring 9. The assembly is heated to cure the resin. Removal of the glass plates 1, 1<SP>1</SP> from the completed disc is effected by removing the screws 15, Fig. 2, that retain ring 14, placing rubber O-ring 17 and plate 18 (Fig. 3) over glass plate 1<SP>1</SP> and reducing pressure in space 21 through connector 20. When bolts 22 are screwed down, the reduced pressure causes glass plate 1<SP>1</SP> to follow plate 18 rather than cobalt layer 3<SP>1</SP>. Glass plate 1 is similarly removed.

In a sytem for automatically maintaining constant the frequency of a rotary inverter or equivalent rotary machine the D.C. excitation of the machine is controlled by a saturable reactor having a pair of control windings each combined with a tuned circuit and supplied from the A.C. side of the machine through a rectifier, one tuned circuit being series resonant and the other being parallel resonant. As shown, the rotor of an inverter has a D.C. input winding a associated with field windings c, d and a three-phase output winding b associated with a field winding e. To stabilize frequency, control windings k, m of a magnetic amplifier controlling the energization of field winding d are energized through rectifiers w, t respectively in series with tuned circuits across the secondary of a transformer x supplied from the A.C. output. The tuned circuits, one of which, s, r, is series resonant, and the other, u, v, of which is parallel resonant, have variable inductances and are tuned to be resonant above the frequency it is desired to maintain. The A.C. winding h of the magnetic amplifier is supplied from the A.C. output in series with a rectifier energizing field winding d. To stabilize voltage, a rectifier g supplied from the A.G. output energises a winding f of a regulator associated with field winding e.

Title: Improvements in control valves for automatic sprinkler installations
IPC: F16K17/00
Filed: 1926-12-30
Abstract: 283,724. Whittingrton, C. H. Dec. 30, 1926. Sprinklers, automatic.-In order to prevent re closing of the control valve of an automatic sprinkler system after it has opened, an hydraulic device actuated by the movements of the valve spindle is provided comprising two members so mounted on the valve spindle as to form an hydraulic chamber between them. In the drypipe arrangement shown, the differential air valve a has a spindle d, the upper part of which is bored at d<1>. A " cup leather " f fixed to the spindle d forms with a second stationary " cup leather " f<1> an hydraulic chamber. When the spindle d rises with the valve a it carries with it the " cup leather " f, the latter exerting a suction which draws a body of water into the hydraulic chamber. This body of water will then resist reclosing movement of the valve a. Upward movement of the valve a is limited by stop surfaces m, m<1> which also form a cut-off valve for the hydraulic chamber. When the valve a is to be reset, a cap g is removed from the upper end of the spindle d, allowing the water to escape from the hydraulic chamber bv the bore d<1> and a slot h, and the valve to sink by gravity.

Escapements.-In an escapement of the lever type, the lever 6, pivoted at 7, carries pallets 8, 8<a> to coact with the scape wheel 5 and also carries an impulse pin 14 and two unlocking pins 15. The impulse pin 14 coacts with a roller 16 on the balance 9, notched at 16<a>, and the unlocking pins 15 coact with a second roller 17 having a lug 17<a>. The relative positions of the pallets may be adjusted by inserting a tool in the slot 19. The scape wheel applies its power through the face of pallet 8<a>. As the balance oscillates, the lug 17 meets one or other of the pins 15 and definitely unlocks the pallets from the scape' wheel. In a modification a separate safety pin on the end of the scape lever, coacts with a crescent-shaped recess in a third roller on the balance staff 10 in order to maintain the correct relative positions of the escapement parts during operation. In this construction also the pallets are spaced on either side of the line between the centres of shafts 7 and 10. Wheels and pinions.-The teeth of the wheels and pinions of the gear train are shaped as shown in Fig. 5 to reduce friction. Alternatively, twin wheels and twin pinions may be used, fixed to the same spindles, the teeth of one wheel or pinion being in alignment with the spaces of the twin wheel or pinion.

Title: Improvements in internal combustion engines of the opposed piston type

Filed: 1936-12-02
Abstract: 473,855. Two-stroke engines. NEIDL, G. Dec. 2, 1936, No. 33117. [Class 7 (ii)] In an internal-combustion engine of the opposed-piston type wherein the opposed pistons are connected to cranks set at an angle of less than 180‹, the ignition of combustible mixture between the pistons, or the injection of fuel into compressed air between them, is timed so that it occurs or begins at the moment when the distance of one of the crank-pins from a dead centre which it has just past is equal to the distance of the other crank-pin from the opposite dead centre, which it is approaching. The cylinder 1 has a bucket piston 2 connected by rods 3 to two cranks on a shaft 4. The piston 5 within the piston 2 is connected to the shaft by a rod 6. The cylinder has ports 9, 10, 11 and the piston 2 ports 12, 13. The port 10 opens into a chamber 14 containing a spark plug 15 to ignite a compressed charge in the space 16. The spark plug may be omitted and the engine operated on the Diesel cycle. The port 9 opens into a chamber 17 connected by a pipe 18 to the crank case and the port 13 opens directly to the crank case. The port 11 opens into an exhaust chamber 20. Chambers 22 are provided with cooling water. Fuel and air are admitted to the crank case and pass when the pistons have moved apart, through port 13, and through pipe 18, chamber 17 and port 9 into the space between the pistons. When the pistons are in the position shown in Fig. 4 with the ports 10, 12 in register, injection of fuel takes place if the engine is a Diesel engine, or ignition by a spark, &c., if the engine is of the gas or petrol type. When the ports 9, 11 register with the ports 12, 13, exhaust takes place through ports 11, 13 with scavenging due to air entering through the port 12. The cranks may be replaced by eccentrics or equivalent mechanism. The pistons may be disced to bring them closer together. In a modification, Fig. 2, the upper piston 25 is connected to the shaft by return connecting rods 27 and carries the piston of a scavenging pump. When working as a Diesel engine, fuel is injected at 33 and air at ports 34, 35 through which the exhaust also passes.
