Title: Device for producing a fog or mist from a vaporisable liquid
IPC: A01M1/20
Filed: 1970-03-10
Abstract: 1298985 Fog-generator BURGESS VIBROCRAFTERS Inc 10 March 1970 [10 March 1969] 11379/70 Heading A5G Portable, hand-held apparatus for producing insecticidal and like fogs comprises a reservoir 14 for liquid insecticide communicating with a coiled duct 57 via a non-return valve in housing 20 (see Fig. 4, not shown, for details) the duct being heated by burning fuel from the pressurised reservoir 16 issuing from the burning nozzle 54, the coil and burner being contained within the cylindrical housing 40. The liquid in reservoir 14 is under atmospheric pressure and is delivered in discrete portions to the heated coil by operation of the "trigger" 21 associated with the handle 12, the trigger actuating a reciprocating cylinder type pumping mechanism 76 in the reservoir. Delivery of fuel is controlled by the needle valve 26 operated by the regulator dial 18.
Patent GB-699770-A (GB)
Title: Improvements in or relating to the preparation of copolymers
IPC: C08F210/12
Filed: 1951-05-16
Abstract: Copolymers are prepared by mixing a major proportion of an iso-mono-olefin, preferably isobutylene, with a minor proportion of a conjugated multi-olefin having from 4 to 8 carbon atoms, preferably isoprene or butadiene, together with 0.1 to 0.8 per cent by weight of a non-conjugated diolefin of the structure <FORM:0699770/IV (a)/1> (wherein x is an integer from 1 to 6), cooling the mixture to 0 DEG to -164 DEG C. and polymerizing with a Friedel-Crafts catalyst dissolved in a low-freezing non-complex forming solvent.  The non-conjugated diolefin may be dimethallyl or 2,4-dimethyl-1,4-pentadiene and the catalyst may be aluminium chloride or bromide, titanium tetrachloride or boron trifluoride dissolved in an aliphatic hydrocarbon such as liquid propane, ethane, butane, hexane or heptane, an alkyl halide such as ethyl or methyl chloride, methylene or ethylene dichloride, propyl chloride or chloroform, or carbon disulphide.  The reduced temperature may be obtained by the use of a refrigerating jacket or by the direct admixture of a refrigerant-diluent such as liquid propane, solid carbon dioxide, liquid ethane or liquid ethylene. The polymerization reaction may be conducted batch-wise or in a continuous operation. The copolymer is soluble in aliphatic and aromatic hydrocarbon solvents and in chlorinated hydrocarbons, and may be compounded with zinc oxide, carbon black, stearic acid and a vulcanizing agent and vulcanized.  A plasticizer such as dioctyl sebacate may be added. The copolymer is particularly suitable for the manufacture of automobile inner tubes. Specification 560,924 is referred to.

Title: Improvements relating to closets
IPC: E03D5/016
Filed: 1948-04-27
Abstract: 639,493. Sanitary closets. BRITISH OVERSEAS AIRWAYS CORPORATION, and SAUNDERS, F. S. April 27, 1948, No. 11555. [Class 26] A closet flushing system comprises a closet basin 8, discharging into a container 14 below floor level, an inner receptacle 21 for retaining solid matter therein, but allowing passage of liquid into the outer space of the container wherefrom a pump 47 raises the liquid to the basin 8 for flushing it. The container 14 is connected to the closet by a neck 12 and a pipe 13 fixed by a flanged joint to the plate 18, to which is also similarly fixed a pipe 19 and a vent pipe 20. The receptacle 21 has an imperforate section 22 and a perforated section 23 most of which opens into the annular space between it and a jacket 26, joined to it by a ring 27, a narrow width of the perforations opening directly into the outer space. The container 14 has a discharge pipe 32, the outlet being closed by a plunger valve 33 closing on to a seating 34 and fitted with a rubber sealing ring 39. The valve 33 is carried by a stem 36, passing through a collar 37 and gland 38, having a handle 40. The outer end of the discharge pipe 32 is closed by a screwed cap 43 removed for cleaning out the solid-matter, after which an external source of water is introduced through pipes 29. This water is preferentially forced through the perforated section 23, to remove any remaining' solid matter, by having a constricted opening or openings, e.g. three or four semi-circular holes at the bottom edge of the jacket 26, whereby filtered liquid flows, when the system is in operation, into the outer space. It is then circulated through pipes 44 and 48 by an electric motor 49 to the basin 8. The current for the motor is supplied through a relay 53, said relay and hence the duration of flushing being controlled by a time switch 56. Fig. 1 shows the system within an aircraft fuselage 6, supported on the ground by a framework 7, a servicing door 16 being hinged at 17 to give access for cleaning the container.

Title: An improvement in or relating to looms having automatic weft-replenishing means
IPC: D03D45/34
Filed: 1948-04-28
Abstract: 637,766. Looms with automatic weft replenishment. BROADHEAD, J. E: April 28, 1948, No. 11580. [Class 142 (iii)'] In a loom provided with automatic weft replenishing means, the replenishment is revoked if the shuttle is incorrectly boxed. As the slay moves forward, a rod c normally passes through a hole d<SP>1</SP> in the shuttle box wall, or in the swell, and into an aligned hole in the shuttle. If the shuttle is incorrectly boxed, the rod c is moved forward and turns a rod f carrying an arm h and rod i connected to the weft replenishing mechanism and thereby renders 'that mechanism inoperative. An arm j, also mounted on the rod f, co-operates with the usual weft feeling mechanism k.

Abstract: 353,018. Indicating liquid level. BAILEY, A. J. and BAILEY, F. M., Albion Works, Salford, Lancashire. April 17, 1930, No. 12166. [Class 123 (i).] In a pneumatic' depth indicator in which a pump supplies air to a dip pipe, and the air pressure due to the head of liquid is measured, a valve device is employed, operated by the air pressure due to the pump, whereby during the working stroke of the pump the passage to the indicator is closed and air can pass only to the dip pipe. The valve device is mounted upon the pump 2 and comprises a diaphragm or piston 6 open on one side by a passage 7 to the pump barrel, and on the other side by a passage 9 to the indicator 1 and by a passage 7a to the dip pipe. When air under pressure is supplied by the pump, the diaphragm 6 is lifted and the passage 9 closed by the valve member 10.

Abstract: 818,116. Variable pitch propellers. HINDMARCH, T. April 15, 1958 [April 15, 1957], No. 12265/57. Class 114. A lock for the prevention of unintentional rotation of a blade in a ship's variable pitch propeller comprises a friction brake member upon the root of the blade 13, a friction brake member in the boss 10 of the propeller co-operating with the brake member upon the root, and fluid pressure operated means for forcing the brake members into braking engagement. The brake members upon the root and in the boss constitute a journal 12 having a conical surface and a conical bearing 11 respectively. Pressure fluid introduced into the interior of the boss 10 acts to force the root of the blade outwardly and thereby engage the conical brake members. The fluid may be supplied via a bore 18 in the blade operating push and pull rod 16 house in the propeller shaft 17. When it is desired to alter the pitch of the blade, the locking fluid pressure is removed. In cases where centrifugal force causes a partial locking of the blade, this may be balanced by supplying pressure fluid to a distribution groove 23 in the bearing 11 via a channel 22.
