Title: Improvements in or relating to gyroscopes
IPC: B63B39/04
Filed: 1919-07-24
Abstract: 160,192. Jackson, P. R., (Sperry Gyroscope Co.). July 24, 1919. Gyroscopic appatatus of the type described in Specification 582/14 for controlling the rolling and pitching of ships, in which precessional motion is impressed on the main or stabilizing gyroscope by means controlled by the precessional movements of an auxiliary gyroscope, is provided with means for automatically adjusting the centralized position of the auxiliary gyroscope so as to maintain the two gyroscopes in phase and thus to equalize the extent of precession of the main gyroscope on each side of its central position; means are also provided for limiting the velocity and the amplitude of precession of the main gyroscope. The rotor 73, Fig. 2, of the auxiliary gyroscope is mounted on an horizontal axis in the ring 74 adapted to process around the vertical axis 72. The ring 74 carries contact points 79, 79<1> adapted to contact with points 80, 81 to control the motor 82, and is centralized by springs 83, 84 bearing against set screws 86 passing through blocks 87 which are threaded upon the shaft 88. Two oppositely-acting ratchetwheels 95, 95<1> are secured to the shaft 88 and are adapted to be rotated by pawls 94, 94<1> which are operated by the solenoids 89, 90. The solenoids 89, 90 are energized by a contact block 120, Fig. 1, which is carried by the main gyroscope and moves over stationary contacts when the gyroscope precesses, so that, should the oscillations of the main gyroscope be chiefly on one side of the central position, either the ratchet-wheel 95 or the ratchet-wheel 95<1> is turned during each oscillation so as to adjust the centralized position of the ring 74. Precessional movement is impressed on the main gyroscope by the motor 82 through gearing 98 - - 103 and in order to limit the velocity of precession a brake 107 is provided around a collar 108 on the motor shaft, the said brake being operated by the core 105 of a solenoid 104 which is drawn in against a spring 106 to release the brake when sufficient current passes through the solenoid, which is in series with the motor 82. The brake is applied when the motor is cut out or when the current falls below a predetermined amount. To limit the amplitude of precession of the main gyro, one of the oscillating gudgeons 3 thereof carries a lug 117, Fig. 4, adapted, when the amplitude of oscillation becomes sufficiently large, to operate one of the arms 118 which opens one of the switches 85, 86<1> and cuts out the motor 82. Specifications 161,133, [Class 12 (iii), Lubricators &c.] 162,604, and 164,285 are referred to.

Abstract: 615,682. Davits. WELIN-MACLACHLAN DAVITS, Ltd., and STEVENS, W. A. June 19, 1946, No. 18490. [Class 115] In a boat-lowering gear for use with davits of the gravity type having a davit carriage 2 which runs on a sloping track 4, the gear is so arranged that when the boat is being hoisted or lowered the tackle between the davit (or its carriage) and a fixed point is " static," i.e. loaded, but the sheaves and ropes stationary. The lead 1 passes over guide sheaves 5, 6, 7 and 8, round a sheave of the floating block 10, thence round block 13 and the other sheave of block 10, round a guide sheave 9 behind sheave 8 and thence round sheaves 17 and 19 to a shackle 21 which forms an anchorage at the inboard end of the track 4. When the boat is being hoisted or lowered to or from the davit head, the lead between the sheave 9 and the sheave 17 and between the sheaves 17 and 19 is " static," i.e. loaded, but the sheaves 17 and 19 and this portion of the lead are stationary.

Abstract: 385,006. Thermionic valves. HUGHES, G., 9, Warwick Court, High Holborn, London.-(Arcturus, Radio Tube Co. ; 720, Frelinghuysen Avenue, Newark, New Jersey, U.S.A.) June 26, 1931, No. 18561. [Class 39 (i).] A pair of insulating plates 22, 23 are fixed to the anode of a thermionic valve by means of tongues 21 on the anode which engage in openings 24 in the plates. The anode consists of two plates 14, 15 with channelled extensions which embrace the supporting rods 57. The openings 24 are provided with notches through which rods 26 supporting a grid 27 pass. The grid 27 prevents secondary emission from the anode. A second grid 29 for reducing the space charge between the anode and cathode is carried by rods 30, 31 which pass through holes in the plates 22, 23. A third grid 32 which forms the control grid is carried by rods 33, 34 also passing through holes in the plates 22, 23. The upper plate 22 is provided with holes 37, 38 and the lower plate 23 has a series of notches 39 .. 44 formed along two opposite edges. These notches receive three metal straps 45, 46, 47 which pass round the plate 23 and are welded underneath to three support rods 59, 60, 61. The filament 48 passes under the strap 46 and is welded at the ends to the straps 45, 47. The upper ends of the filament are carried by hooks which are supported by springs 49, 51. Certain of the grid supporting posts are anchored to the plate 23, by means of clips 54, 55, 56 which are welded to the posts 26, 31, 33 and grip the plate 23. The remaining supporting posts extend below the plate 23 and are welded to rods 58 &c. extending from the pinch 13. The outer grid which prevents secondary emission from the anode is connected to the cathode by means of a strap 63. This places a negative charge on the outer grid. The middle grid 29 is supplied with a positive potential greater than that of the cathode and less than or equal to that on the anode.

Title: Improvements in or relating to the manufacture of condensed products from formaldehyde
IPC: C08B37/00
Filed: 1930-06-19
Abstract: A mixture of glycollic aldehyde, trioses and tetroses (d, l-threose and d, l-erythrose) is prepared by condensing formaldehyde in alkaline solution by heating until the reduction power of the reaction liquid for cold Fehling's solution has reached a maximum. As condensing agents, organic bases, metallic hydroxides or suitable salts may be used and the condensation may be carried out in aqueous or alcoholic solution or in a mixture of water and alcohol.  The products obtained may be hydrogenated to give a mixture of glycol, glycerine and erythrites.  In an example, formaldehyde is condensed in aqueous solution containing lead hydroxide to a mixture of glycollic aldehyde trioses and tetroses.  The lead is precipitated by oxalic acid, and the products are reduced to the corresponding alcohols which are separated by fractional distillation in vacuo.

Abstract: 597,592. Security boxes. WEISSMANN, W., and WEISSMANN H. July 23, 1945, No. 18873. [Class 18] [Also in Group XXV] A security receptacle comprises a box 1 detachably mounted on a plate 20 secured to a support and a latch that serves to hold the lid 3 in the closed position and to secure the box to the plate 20. The walls of the box extend below the bottom 4 to form a recess which encloses the plate 20. A flanged plate 7 is mounted on the inside of the front wall and houses the latch device which consists of a bar 12 slidably mounted on pins 13 and provided at each end with a latch bar 15. Each latch bar 15 has projections 16, 17 which engage with lugs 11, 24 respectively on the lid and the plate 20. A channel shaped strip 6 is secured to the bottom of the box to engage a lip 23 formed on the edge of the plate 20 remote from the lugs 24. The bar 12 and latch bars 15 are urged in an engaging direction by a spring 19 so that the projections engage the lugs on the plate 20 and on the closed lid. To open the box, the bar 12 is moved to disengage the latch bars 15 from the lid and the plate 20 by a key operating a series of tumbler levers 28 and striking an arm 26 on the bar 12. At the same time ,a pawl may be arranged to engage a notch in the bar 12 and maintain the bar in a disengaged position, the pawl being tripped by a lug on the lid when the lid is closed. Alternatively the latch bars may be disengaged from the lid, whilst still securing the box to the plate 20, by part rotation of the key further rotation being necessary to disengage the box from the plate 20. Simultaneously, as the box is disengaged from the plate 20, the latch bars may re-engage the lid so that the box may be lifted by a handle secured to the lid, The box may be constructed of steel and lined with asbestos sheet and the lid may be urged to close by gravity or pneumatic or fluid spring control device.
