Title: Guanidine sulphamate
Filed: 1952-05-16
Abstract: Guanidine sulphamate is produced by heating, in the absence of water, a mixture of urea, ammonia and sulphur dioxide at a temperature of at least about 220 DEG C. in a reaction zone maintained under a superatmospheric pressure of ammonia for a period of time at least sufficient to initiate the reactions between the reactants to form guanidine sulphamate, and separating and recovering guanidine sulphamate from the reaction product.  The process can be operated at temperatures in the range of about 220 DEG -360 DEG C. or above. Preferably the pressure of ammonia is from 200 to 1,000 lbs. per sq. in. and a molecular ratio of sulphur dioxide to urea of at least 3:1 is used.  Guanidine sulphamate may be separated from the reaction mixture by leaching it with an aqueous solution saturated with guanidine sulphamate and ammonium sulphate.

Abstract: 256,696. Higgins, E. L. May 13, 1925. Locks, permutation; attaching; locking sliding latches.-A lock of the coaxially mounted locking ring type has staggered projections on the bolt and duplex rings frictionally held so that in the intermediate position of the bolt the inner rings are held, while the outer rings are rotated to change the combination. Fig. 1 shows such a lock with the bolt 38 withdrawn and the staggered projections 39 turnable in recesses in the inner rings 40 after having passed the gates 41. When the bolt is shot, the projections re-pass through the gates and are within the recesses of the adjacent rings. To change the combination, the bolt is moved to the intermediate position when the projections 39 are in the gates 41 and hold the inner locking rings 40 while the outer setting rings 42 are rotated to the new combination. The pairs of rings 40, 42 may be held in frictional engagement by a leaf spring housed in a recess. The rings may be mounted in a casing 37 provided with an aperture 46 for setting, and viewing apertures 48, or the casing may be dispensed with. False notches may be provided to prevent picking. The setting rings have a milled part 45 for setting and nicks 49 coacting with spring plungers 50 to maintain their adjusted position. The bolt 38 may block a door latch 58, Fig. 5, or engage a socket 55 to lock window sashes, Fig. 4, in which case the casing 37 is integral with an attaching bracket 51 secured by a screw 53.

Title: Composite closure caps
IPC: G01T1/36
Filed: 1974-03-21
Abstract: 1470585 A two element closure assembly CONTINENTAL CAN CO Inc 21 March 1974 [16 April 1973] 12559/74 Heading B8T A closure assembly for a container comprises a lid 16 which is made of a rigid material 1 and seated in an annular member 12 having a depending skirt 22, the lid being held in position by lugs 32<SP>1</SP> extending inwardly from the skirt. A vacuum seal is maintained prior to opening by an annular gasket 42 disposed between the lid 16 and the rim 28 of the container, the rim being formed by the open end of the container being turned back upon itself and forming an annular collar 58 which engages the inner surface 52 of the depending skirt. The free end of the depending skirt engages an annular bead 46 which is formed in the wall of the container and which extends radially outwardly, beyond the outer surface of the skirt, thereby protecting the closure assembly when the sealed container is packed in close proximity to others. A ring member 20 is connected to the annular member 12 via a belt 124 and held in contact with lid 16 by frangible webs 24, 26. Removal is effected by breaking the webs and exerting a tensile force on belt 124 via ring member 20, thereby breaking the seal and separating the closure from the container. During the removal process the belt 124 is bent at a region 126 disposed radially inwardly from the edge of annular member 12, this having the effect of pressing the depending skirt in the vicinity of the belt, against the container wall thus preventing premature rupture of the seal. The sealing between closure and container may be facilitated by lugs 34 disposed on the inner surface of the depending skirt at a region between the annular collar 58 and bead 46, the lugs engaging the side of collar 58 remote from rim 28.

Patent GB-666906-A (GB)
Title: Improvements in electrical multiplex signalling systems
IPC: H04J3/04
Filed: 1949-05-13
Abstract: 666,906. Electrical distributers. GENERAL ELECTRIC CO., Ltd., and CHUBB, A. A. March 22, 1950 [May 13, 1949], No. 12814/49. Class 40 (iii). [Also in Group XL (c)] An electrical distributer arranged to distribute signals from a line to a number of channels or vice versa employs a plurality of signalling paths, each of which comprises two rectifiers connected in series in the path, the rectifiers being so biased and connected to a source of saw-tooth potential that the paths become conductive and subsequently non-conductive in a predetermined order. As shown, each path includes two rectifiers such as oxide, selenium or germanium crystal elements, the centre connections between the rectifiers being returned through inductances L1-L4 to a tapped source of negative bias P increasing in steps of, say, 4 volts from the leftto right-hand path. Rectifier MRK provides a further position bias of 4 volts through transformers T1-T4 to the upper rectifiers MRA-MRD. The biasing arrangement is such that in any path the bias across the upper rectifier is 4 volts greater and in the reverse direction to that across the lower rectifier, and the directions of bias are such that rectifiers MRA-MRD are normally conductive and rectifiers MRE-MRH non-conductive. A source of positive-going saw-tooth potential ST is connected to all paths through lead 5 and applies a potential increasing to 4N volts, where N is the number of paths. Starting at zero potential, rectifier MRE is first rendered conductive, opening path 1. After the saw-tooth potential has risen through 4 volts, the potential across rectifier MRA reverses, rendering it non- conductive and closing the path again. At this level, however, rectifier MRF becomes conductive and opens path 2. After the sawtooth has risen through a further 4 volts, rectifier MRB becomes non-conductive and rectifier MRG conductive, so closing path 2 and opening path 3. This process repeats in like manner for the remaining rectifiers, opening and closing the paths in sequence. The saw-tooth generator may operate step-wise, passing rapidly from one path-opening potential to another. The steps of the tapped bias source may be made greater than the bias due to rectifier MRK to reduce overlapping between the path attenuation curves. Limiting resistors R1-R8 are made equal to the geometric mean of the forward and backward resistances of the rectifier elements. In order to synchronize two such distributers at each end of a line an alternating current signal is applied through lead 10 at the originating distributer to the first path when the saw-tooth generator commences its waveform. This signal is extracted by a filter at the receiving end and applied as a start signal to trigger the receiver saw-tooth generator. To allow for lack of strict synchronism between the sawtooth waves, a gating valve operating at N times the saw-tooth frequency may be employed in the line at the receiver to pass bursts of signal to each path at the mid-point of time when the path is conductive.

Filed: 1973-03-19
Abstract: 1401731 Echo-sounding TEXACO DEVELOPMENT CORP 19 March 1973 [1 May 1972] 13048/73 Heading H4D Wave height is measured from a floating marine structure by determining the vertical distance from a submerged reference point on the structure to the water surface and the vertical distance from the reference point to the water bottom and combining the two distance determinations. In embodiments described the structure is a semi-submersible drilling platform, the distance below the reference point is determined by echosounding, and the distance above is determined by echo-sounding or by a pressure-responsive device. The echo-sounding beams are maintained vertical by a gimbal system, or else the beams can tilt with the platform and the distance measurements are corrected to allow for the tilt. The distances are recorded using a dual-pen recorder. The wave and swell pattern can thus be determined so that apparatus for stabilizing the drill string position can be programmed to be actuated in advance of anticipated movement of the platform.
