Patent GB-521160-A (GB)
Title: Improvements in or relating to gyroscopic instruments
IPC: G01C19/34
Filed: 1938-11-09
Abstract: 521,160. Gyroscopic apparatus. REID, G. H. Nov. 9, 1938, Nos. 32574/38 and 7917/39. [Class 97 (iii)] In a resetting device for a gyroscopic direction indicating instrument having three degrees of freedom relative to the casing, the outer gimbal 15, Fig. 1, carries co-axially with its mounting axis 17 an axially slidable ring 39 which rotates with the outer gimbal and may be displaced by manually operated means to bring the inner gimbal 19 to a predetermined caged position relative to the outer gimbal. The resetting means may be used to restrain the gyroscope for use also as a rate of turn indicator. The gyro rotor 22 is driven by air drawn through filters 30, 29 and nozzles 25, by the effect of a Venturi connected to a pipe 26. The outer gimbal 15 carries a graduated direction scale 13 read against a lubber line. To reset the instrument, a knob 34, Fig. 3, is pushed in, to place a bevel pinion 32 into engagement with bevel teeth 31 on the outer gimbal 15. A conical member 51 at the same time liberates a forked lever 46, rocked by springs 48, to raise the slidable ring 39 into engagement with a cam 37 secured to the axle of the inner gimbal. The cam is thus urged into its central position to set the spindle of the gyro rotor in an 'horizontal position. By rotating the knob 34 the outer gimbal 15 may be set, the precessional forces of the rotor being met by the .resilience of the springs 48. In a modification, the ring 39 instead of sliding, pivots on the outer gimbal. By employing weak springs 48 the instrument may be used also to indicate rate of turn. In this form the cam 37 carries a pointer 55, Fig. 6, which may be read against a scale 56 on the outer gimbal 15. In use, the abovedescribed bevels 31, 32 are used to lock the outer gimbal 15 in a predetermined position with the pointer 55 and scale 56 in register. Any turning movement of the instrument about a vertical axis then causes the inner gimbal to cant over due to precession, and the cam 37 to overcome the weak springs 48 and give a rough indication of the rate of turn. Specification 471,217 is referred to.
Patent GB-157882-A (GB)
Title: Improvements relating to safety locks
IPC: E05B29/00
Filed: 1920-11-18
Abstract: 157,882. AbbÚ, J. Jan. 19, 1920, [Convention date]. Locks, revolving-barrel.-The blocking-elements of a revolving-barrel lock are constituted by a series of discs b, which on axial insertion of the key are angularly adjusted so as to permit the cylinder to be pressed in axially and make connection with the bolt-operating means. Two toothed bars e are fitted within the casing c, Fig. 1, in such a way that the teeth f on one bar are opposite the notches in the other. Each tooth acts as a stop to limit the rotation of that disc b which is in its own plane, and also blocks the disc lying in front of it against being pushed in until it has been properly arranged by the key to align the notch j, Fig. 12. The discs are connected in pairs by spiral springs which disarrange them when the key is withdrawn. As shown in Fig. 12, they are formed with an opening having a face r working in conjunction with a key, Fig. 5, having the section shown in Fig. 6, but in which the inclination of the part q varies according to the position along the axis at which the section is taken. When the key is fully inserted, all the .discs are so arranged that the notches are aligned with the teeth f lying behind them, and the inner cylinder, together with the discs, can be pressed inwards. This movement releases projections upon the rear end of the inner cylinder from engagement with the outer case, and enables the inner cylinder to turn, and actuate the bolt-operating connection p. In a modification, the key has a sinuous groove formed upon its surface to engage with projctions upon the discs b so as to set them in the necessary position.

Title: Improvements in or relating to the manufacture by extrusion of aluminium containers
IPC: B21C23/22
Filed: 1958-09-18
Abstract: 843,964. Making containers; extruding; welding by pressure. METAL BOX CO. Ltd. Sept. 18, 1958 [Oct. 18, 1957], No. 32620/57. Classes 83 (2) and 83 (4). An aluminium container, Fig. 2, is made by backwardly extruding a ring-shaped aluminium blank 5, Fig. 1, whilst seated on an aluminium disc 4 whereby the ring forms the container wall 6 and the disc an integral bottom 4. The disc is preferably harder than the ring to facilitate preferential flow of the latter; they may be cold-pressure-welded together initially or may be cold-pressure-welded together during the extrusion. The ring 5 may be out from an extruded aluminium tube and the disc blanked out of aluminium plate; both are fed immediately to the extrusion die 1, Fig. 1, in synchronism with the operation thereof, through tunnels containing an inert gas which precludes oxidation of the aluminium and hence facilitates the cold welding. Within die 1 the ring 5 is backwardly impact-extruded by an annular punch 2 containing a spring-loaded hold-down plunger 3 acting on the disc 4, and simultaneously a cold-pressure-welded joint 7 is produced.

Abstract: 1,009,201. Finishing fabrics. HOSIERY & ALLIED TRADES RESEARCH ASSOCIATION. Dec. 27, 1961 [Sept. 23, 1960], No. 32692/60. Heading D1S. Knitted tubular fabric is treated to reduce its liability to shrinkage arising from subsequent laundering by mechanically changing the dimensions of the fabric, whilst under the action of steam or other heat, by stretching the fabric widthwise while it contracts lengthwise followed by maintaining the reduced length while reducing the width. Widthwise stretching may be obtained on a stretcher 1, Fig. 1, over which the fabric is traversed by by two pairs of parallel rollers 2, 3 and 4, 5, the second pair of rollers being arranged to rotate more slowly than the first. Width reduction may be effected by passing the fabric between a pair of belts formed of elastic members, such as coil springs 23, Fig. 4, which can be adjusted to converge to desired widths by manipulation of a handle 43 on an appositely screw-threaded spindle 44. This width reduction apparatus forms the subject-matter of Specification 1,009,201. Arrangements are provided for carrying out both steps under the action of steam or other heat.

Patent GB-443800-A (GB)
Title: Improvements relating to the thermal decomposition or volatilization of liquid carbonaceous material
IPC: C01B17/58
Filed: 1934-11-14
Abstract: <PICT:0443800/III/1> Fluid materials which are decomposed by heat treatment into a volatile portion and a carbonaceous residue are heated by contact with sufficient heated finely divided solids such as sand to decompose the fluid material, the volatile products being removed from the heating zone, the intimate mixture of heating medium and carbonaceous residue being removed and the heating medium being reheated solely by burning at least a portion of the carbonaceous residue in intimate contact therewith.  The process may be applied to the decomposition of sludge from the sulphuric acid purification of carbonaceous materials to yield sulphur dioxide or to the distillation of petroleum fractions.  When the coke in the sand-coke mixture is not completely burnt in the re-heating step, a hot mixture of coke and sand is brought into contact with the fluid materials in the next cycle, in this way sand is gradually eliminated and coke itself serves as the solid heating medium. Hot sand at about 820 DEG C. is fed into a revolving kiln 1 by means of a screw 2 while acid sludge is pumped in by a pump 4.  A mixture of sand and coke is discharged at 6 while the evolved gases containing sulphur dioxide pass out through a gas outlet 5. The mixture of coke and sand is transferred by a conveyer 7 and elevator 8 to a heating kiln 9 where the coke, ignited by a pilot flame 21, burns to reheat the sand for further use.  The gases passing through the gas outlet are purified and worked up to the production of sulphuric acid as described in Specification 443,452.  Specifications 189,542, [Class 32], and 398,023 also are referred to.  Reference has been directed by the Comptroller to Specification 189,542.

Abstract: 654,958. Blasting cartridges. CARDOX (GREAT BRITAIN), Ltd., LORING, E. A., SHIMMIN, T. A., and BRAY, N. Dec. 20, 1948, No. 32876. [Class 9 (i)] A blasting cartridge has a pressureresistant steel casing in two screwconnected sections 1, 2 providing front and rear chambers 3, 4 separated by a partition 5. The partition 5 is a rupturable steel disc with a restricted aperture 7 through which the front chamber 3 is filled with liquid carbon dioxide. The front section 1 has a shoulder 11 on which is seated a rupturable closure disc 13 held in position by a discharge head 54 as in Specification 517, 417. Screwed into the section 2 is a firing head 6 as described in the aforementioned Specification. In the rear chamber 4 is an initiator 14 comprising a paper container 15 filled with a heating or gas-producing composition 16 with a matchhead 17 embedded therein as described in Specification 617,417. The composition is preferably as described in Specifications 617,136 and/or 480,330. The rear chamber may also contain liquid CO 2 . The cartridge is charged with liquid CO 2  as described in Specification 387,068, the liquid flowing through a passage 18 in the firing head into the rear chamber and thence into the forward chamber. The partition 5 may be imperforate, a byepass passage in the casings connecting the chambers 3, 4 or the chambers may be filled independently. If the initiator is filled with a heat-producing composition, on firing the liquid CO 2  is converted into gas and the increased pressure ruptures the partition 5 propelling the charge in the front chamber into the borehole, while in a liquid state, to produce fissures; the liquid expanding into gas in the fissures completes the blasting action. With a gas-producing initiator, the liquid CO 2  in the initiator chamber may be omitted. The partition separating the charge chamber from the initiator chamber may form a unitary structure with the initiator. In one arrangement the initiator chamber is within the firing head.

Patent GB-760711-A (GB)
Title: Improvements in methods of and apparatus for transmitting variable information
Inventor: DUBOURG JEAN DIPL ING
IPC: G08C15/04
Filed: 1953-11-26
Abstract: 760,711. Electric telemetering systems. HEWITTIC SOC. A R.L. Nov. 26, 1953 [Nov. 26, 1952; April 28, 1953], No. 32900/53. Class 40 (1).  A telemetering system comprises means for simultaneously transmitting over one line the values of a series of different variables as corresponding frequency modulations of a series of different carrier frequencies, the receiver comprising means for cyclically varying the frequency of an oscillator which beats with the combined signals so that for each arrangement of the cyclic connections a predetermined beat frequency is obtained from only one of the carrier frequencies, which is demodulated to give the value of the corresponding variable. As shown (Fig. 1) the value of a variable at each of a series of stations 9-14 determines the modulation frequency of a carrier frequency F1-F6 respectively, all of which are fed into a line 16. At the receiver a two-bank stepping switch 5 operated by a magnet 15 varies, at one bank 5a, the frequency of an oscillator 2 in such a way that at each position of the wiper of the switch bank the output frequency of the oscil. lator beats with one of the transmitted carrier frequencies F1-F6 to give a predetermined beat frequency F0, which is fed through a band-pass filter 3 tuned to frequency F0 and a demodulator 4 through the wiper of the other switch bank 5b to the corresponding amplifier 6 and meter 7. The amplifiers 6 each have a large time constant to hold the measuring values throughout the whole of the measuring cycle. In another em. bodiment (Fig. 2) the outputs of demodulator 4 are recorded in individual colours on a moving strip 20. A drum 31 is driven by a motor 36 so that a protruding finger 32 first closes contact 33 to energize the stepping magnet 15 to select the next frequency on the oscillator 2, then closes contact 34 to drive a multi-coloured ribbon 22 to the appropriate position, and finally closes contact 35 to energize a coil 28 which causes a spring-loaded pointer 25 controlled by the output of demodulator 4 to strike the recording strip 20 through the ribbon 22, producing a dot on the strip 20 having a colour characteristic of a particular one of the transmitters. In a modification the stepping magnet 15 also steps the coloured ribbon 22, and contact 34 is not required. In a further embodiment the pointers of meters 7 are locked in the indicating position except for the short measuring period in each cycle when an unblocking device, energized via a third bank of switch 5, releases the pointer to achieve its latest indicating position. Specification 546,754, [Group XXXVI], and French Specification 972,936 are referred to.

Title: Improvements relating to 2-benzothiazolyl sulfene morpholide
IPC: C08K5/00
Filed: 1953-11-27
Abstract: 2-Benzothiazyl sulphene morpholide is manufactured by treating 2-benzothiazolyl disulphide in an inert organic solvent with at least an equimolecular proportion each of N-chloromorpholine and of morpholine in the presence of an acid acceptor.  Preferred solvents are hydrocarbons and halogenated hydrocarbons of the benzene series, whilst the acid acceptor is advantageously an amine, preferably a tertiary amine or excess of morpholine.  The N-chloromorpholine may be prepared by chlorinating morpholine in situ in the solvent to be used in the condensation.  The acid acceptor may be regenerated for further use by treating it, either in the reaction mixture or after separation and re-slurrying in an anhydrous inert solvent, with ammonia and separating the ammonium chloride formed.  When morpholine is used it may be chlorinated before being recycled.  In examples (1) 1 mol. of 2-benzothiazolyl disulphide is added to a solution of 1 mol. of N-chloromorpholine and 2 mols. of morpholine in toluene, which is then stirred at 30-45 DEG  C., after which the mixture is saturated with anhydrous ammonia, the ammonium chloride formed is filtered off, morpholine is extracted with water and the toluene steam distilled; (2) the toluene in (1) is replaced by chlorobenzene and the proportion of morpholine is increased slightly.
