Patent GB-177774-A (GB)
Abstract: 177,774. Krupp Akt.-Ges., F. April 1, 1921, [Convention date]. Ball bearings.-Each of the bearings for the horizontal pivots of a gyroscope mounting is composed of two ball bearings, one, the main bearing, intended mainly to take up vertical load, while the other, the auxiliary bearing, mainly takes up horizontal and transverse forces. Fig. 1 shows the general arrangement, the gyroscope being mounted on a vertical axis in the ring M pivoted at m<1>, m<2> in the ring B, which is pivoted at b<1>, b<2> in the fixed support A. Each of the pivots b<1>, b<2>, m<1>, m<2> is mounted in a bearing of the form shown in Fig. 2. The inner race D of the main bearing surrounds the pivot b<1> and the outer race C is mounted in the support a<1>. Between the races are two rings of balls, staggered in relation to each other, the balls being much smaller than those usually employed. The race D is retained in position by a shoulder on the pivot and by a flange b<3> formed on a pin b<4> which is screwed axially into the pivot b<1>. The inner race F of the auxiliary bearing surrounds the pin b' and the outer race consists of a boss g<1> on a disc G which bears against the race C. This bearing also has two rings of small balls. The disc G has a projection g<2> entering a recess c<1> in the member C to prevent relative rotation of these parts, and can be, locked in position by screwing up a member J. A rectangular member K passing through an aperture in the support a<1> can be pressed against the rim of the disc G by turning a screw E. The load due to the weight of the gyroscope &c. is taken by the main bearing and produces uneven loading of the balls as shown in Fig. 2. The floating disc G prevents any of this load from being applied to the auxiliary bearing, which takes up horizontal pressures such as those due to rolling of the ship &c. carrying the gyroscope. Should the horizontal thrust be transmitted to the main bearing sufficiently to produce deviation of the gyro-axis, compensation may be effected by vertically loading the balls in the upper part of the auxiliary member by pressing down the member K against the disc G.

Abstract: 1,071,779. Reinforced resin articles. UNIVERSAL MOULDED FIBER GLASS CORP. May 4, 1964 [May 6, 1963], No. 18429/64. Addition to 1,071,778. Heading B5A. The method of the parent Specification 1,071,778 is modified in that the parting strip or travelling carrier (13) is coated with a heatcurable liquid resin and heated to convert the resin to an at least partially cured but still soft condition so as to be capable of bonding to another resin, and then at least the coated side of the carrier is contacted with a fibrous reinforcement impregnated with a heat-curable liquid resin material and the resulting combination is pulled through the heated forming passage of a die. As shown in Fig. 1 (not shown), the carrier (13) is deflected by a guide (19) downwardly into a bath (20) of liquid resin material, is passed through an oven (21) heated e.g. by electrical heating lamps (22), and is then fed together with fibrous reinforcement strips (25, 26) through a resin pan (12) and forming device (11). Alternatively only one side of the travelling carrier may be coated, for example by spraying. A single reinforcement strip in contact with the coated side of the carrier strip may then be pulled through the forming passage of the die, or two strips, one on each side of the carrier, may be used, in which case two articles will be formed, one having a resin-rich surface, and the other having fibrous reinforcement elements dispersed through its entire section. The carrier may be coated with wax, e.g. by passing it between rollers (34) in a container (33) containing powdered wax before coating it with resin. As seen in Fig. 5 (not shown), the windup-reels (30a), (31a) for the finished articles may be positioned intermediate the discharge end of the forming device (11) and the puller mechanism (7) so that the pulling force is applied only to the carrier (13).

Filed: 1966-04-28
Abstract: 1,149,012. Fluid-pressure servomotor systems. HONEYWELL Inc. April 28, 1966 [May 18, 1965; July 22, 1965j, No.18802/66. Heading G3P. A fluid-pressure regulating valve having a uniform outlet pressure comprises a main valve 25, controlling the flow from an inlet 12 to an outlet 13, which is connected to a diaphragm 21 bounding a fluid-pressure chamber 23. The chamber 23 is connected to the inlet 12 through a restriction 37, on-off valve 33 and passage 44. The pressure in chamber 23 actuating the main valve is controlled by a pilot valve 55 actuated by a diaphragm 54 which is subjected to the pressure in the outlet chamber 15 through passages 42, 53. The diaphragm is loaded by a spring 70 which engages a sliding abutment 66 having a flange 67 movable between adjustable abutments 60, 61. The passage 47 from the chamber 23 is also connected through a restriction 74 to a chamber 72 above a diaphragm 56. In operation with the on-off valve 33 in the position shown, the chamber 23 is connected through valve 33, chamber 41 and passage 42 to the outlet, which is at atmospheric pressure and the valve 25 is closed by spring 26. If the on and off valve is now actuated, for example in response to temperature, the valve 33 moves upwards to open the chamber 23 to the inlet through the restrictor 37 and the main valve opens to allow flow to the outlet. The outlet pressure now acts through passages 42, 53 on diaphragm 54 to open the valve 55 at a predetermined outlet pressure which restricts the pressure in chamber 23. As the flow through restriction 74 to chamber 72 increases the pressure acting on diaphragm 56, the diaphragm moves the spring abutment 66 downwards to increase the loading of spring 70 and thus increase the regulated output pressure at 13. In a modification, the valve 55 is replaced by two valves in parallel one of which has a light loading and this valve is held closed after actuation of a diaphragm similar to 56, and the second valve has a greater loading to provide the higher output pressure. In a further modification, two control valves are used actuated in sequence by a temperature thermostat through a lever mechanism.
