Title: Improvements in means for draining liquid gas systems
Inventor: HOARE DAVID JOHN RICHARD
IPC: F16K24/00
Filed: 1959-12-19
Abstract: 968,323. Pipe couplings. NORMALAIR Ltd. Dec. 14, 1960 [Dec. 19, 1959], No. 43228/59. Heading F2G. In a filling and venting unit for a liquified gas converter 12 having a bayonet connection 33 for a filling hose and a double-acting valve 19 operated through a stem 21 on connection of the hose to open a vent passage 18 and close the delivery passage 17, a non-return valve 23 in the passage 14 through which the liquid gas is fed into the converter is provided with a stem 24 by which the valve can be tilted for draining the converter. The unit has a build-up circuit similar to that of Specification 846,799. During filling, the filling hose connector mates with the tapered seat 41 without moving a spring-loaded sleeve 36 in which the stem 21 is guided, and valve 19 is moved to open the vent 18 and close the gas delivery port 17. To drain the converter 12, a drainage hose 52, Fig. 2, with an insulated connector 50 is connected to the bayonet fitting 33 and initially the end face 57 of a sliding spring-loaded sleeve 56 therein butts against the end face of the sleeve 36. On operation of a cam 65 by a lever 67, the sleeve 56 is moved to force back the sleeve 36 against spring 37 so that the end of the sleeve 36 contacts stem 24 and tilts the non-return valve 23 to permit the liquid gas to be forced under pressure through the space 22 to hose 52; during this operation valve 18 remains in its normal position closing the vent passage 18. Sleeve 36 returns to its normal position automatically on release of lever 67. Reference has been directed by the Comptroller to Specification 846,799.

Title: A process and apparatus for the manufacture of a crimped multifilament yarn, as well as the yarn thus manufactured
IPC: D02G1/02
Filed: 1965-10-12
Abstract: In a continuous process for stabilisation of multifilament, false-twist crimped and heatset, nylon or polyethylene terephthalate yarn immediately following its travel through a crimping zone, the released yarn is heated by passage in a plurality of turns around a grooved, cylindrical roller which is rotated at constant speed.  The roller is internally e.g. electrically, heated in such manner that its temperature increases in its axial direction and therefore the temperature of the yarn increases e.g. from 100 DEG -180 DEG C, linearly in its direction of travel to a final value higher than the setting temperature.

Patent GB-1447278-A (GB)
Title: Control mechanism for a camera
IPC: G03B7/00
Filed: 1973-09-21
Abstract: 1447278 Exposure control ASAHI KOGAKU KOGYO KK 21 Sept 1973 [22 Sept 1972] 44390/73 Heading G2A A camera has two scales 2, 31, each carrying both a range of shutter speeds and a range of factors by means of which these speeds may be multiplied, a control member by which one of these values may be selected on one scale and set, and coupling means to locate the corresponding value on the other scale to be visible in the viewfinder. As shown, the scale plate 2 carries on the left hand side a series of conventional shutter speeds, which may be set manually, or automatically by a light-sensing device, and on the right hand side a series of multiplication factors which can be used to modify the shutter speeds according to the operator's own judgment and discretion. The scale plate 2 is rotated by means of a dial 1, which is connected to it by means seen in more detail in Fig. 1 (not shown). Rotation of dial I also causes rotation of a gear 18, which meshes with a gear 19. Rotation of gear 19 causes rotation of a reel 26 on which is wound a cord 27 having one end attached to a scale tape 31 on which are marked the same shutter speed and multiplication factors as on scale plate 2. Tape 31 winds on to a spring-loaded drum 30. Thus as any selected value on disc 2 is brought into register with an index mark 24a, the corresponding value on tape 31 is brought into the view-finder. Rotation of dial 1 also causes rotation of a pair of meshing gears (10, 12) which are coupled to a gear 32 which engages with a brush ring 33. Rotation of ring 33 causes corresponding variation in the contact position of a brush 34 on a resistor 35. When automatic exposure is being used, the value of resistor 35 controls the shutter speed. Figures on a scale indicating film sensitivity are visible through a window 2a in scale plate 2, and this value can be adjusted by rotating dial 1 after lifting it against the action of a spring (6), so that it is disengaged from scale plate 2, and therefore plate 2 and tape 31 are not moved. The contact position of brush 34 and resistor 35 is changed, however, in accordance with the film sensitivity value. If manual control of the shutter speed is to be used, plate 2 is rotated to bring the required value against the index 24a. In this mode, a cam 17, linked with the movement of plate 2, opens contacts 37, 38 of a switch in the shutter control circuit, which is hence not operative. If automatic control is adopted, then scale plate 2 is adjusted to bring the selected multiplication factor in register with index 24a, which adjustment causes cam 17 to close the contacts 37, 38, and hence the shutter control circuit becomes operative.

Title: Improvements in or relating to fire-arms that can be fired automatically or semi-automatically
IPC: F41A19/33
Filed: 1964-02-07
Abstract: 1,046,323. Trigger mechanisms. SOC. ANON. STAR, BONIFACIO ECHEVERRIA. Feb. 7, 1964, No. 46363/65. Divided out of 1,046,322. Heading F3C. A trigger mechanism for a firearm comprises a trigger 14 pivoted loosely on a pin 15 and having a lever 10 pivoted thereto, a breech block retaining member 9 loosely pivoted on a pin 16 and a spring-loaded plunger 12 acting between the lever 10 and the member 9. The trigger may be actuated in each of two ways to cause the firearm to fire automatically or single shots. Semi-automatic firing takes place if the trigger is squeezed on the lower arcuate front portion which causes the lever 10 to move ,upwards to pivot the sear 9j downwardly to release the breech-block. The member 9 then moves rearwardly under the action of the spring-loaded plunger clear of the end 10b of the lever 10, slot 9h moving relative to pin 16 so that it can assume a breech-block retaining position even when the trigger remains squeezed. Automatic firing takes place when the trigger is squeezed on the upper arcuate front portion which causes the trigger to first move axially, slot 14 in moving relative to pin 15, and then to pivot the member 9 and release the breech block. Axial movement of the member 9 thereafter under the action of the plunger 12 is not sufficient to move the end 9l clear of the lever end 10l so the member 9 is retained in a position clear of the breech block to permit automatic firing until the trigger is released.

Abstract: 1,185,499. Measuring knock-rating of fuels electrically. BRITISH PETROLEUM CO. Ltd. Oct. 11, 1968 [Oct. 13, 1967], No.46877/67. Heading G1N. The apparatus utilizes knock detection apparatus, such as that described in Specification 1, 125, 991, and applies a first signal to continuously advance the ignition timing of an I. C. engine and a second signal representative of knock frequency to retard the ignition timing so that it is automatically maintained at the critical setting for the onset of knocking. In Fig. 2, sparking plugs 32 are fired by a transistorized ignition system 34 controlled from distributer contact breakers 38 via a delay unit 36 of which the delay is controlled by a pulse frequency-voltage converter 40 fed from knock detection apparatus 30 so that the delay time is progressively reduced until knocking occurs and subsequently increased in proportion to knock frequency so that a critical setting is maintained. The ignition timing is then measured from the delay time and the engine speed by counting the ignition pulses. In the embodiment of Fig. 3 either the distributer body or the contact breaker plate is rotated by a stepping motor 42 in a direction dependent upon the polarity of the input pulses. Knock-representative signals from the detector 30 are fed through a pulse shaper 50 to a motor drive 46 which retards the ignition, a similar drive 44 being fed from a pulse generator 48 so as to continuously advance the ignition.

Copolymerizable monomers specified are diallyl phthalate, triallyl cyanurate, methyl methacrylate, styrene, ethylene glycol dimethacrylate and trimethylol propane trimethacrylate and copolymerizable resins are di(alkyl)acrylate esters of glycidyl polyethers of bisphenol A.
Patent GB-1561494-A (GB)
Title: Process and apparatus for oxidizing cycloalkanes
IPC: C07B61/00
Filed: 1976-11-16
Abstract: A cycloalkane is oxidised in the liquid phase at elevated temperatures and under elevated pressure to the corresponding mixture of cycloalkanone and/or cycloalkanol by means of a gas containing molecular oxygen. A dissolved metal salt is used as a catalyst and the reaction is carried out in the absence of a boric acid derivative. The water concentration of the cycloalkane to be oxidised is reduced before the latter is introduced into the oxidation reactor. Unconverted cycloalkane is removed from the reaction mixture and recirculated into the oxidation stage. The new process reduces the soiling of the reaction vessels and counteracts the occurrence of oxygen strikethrough.
