Title: Low flow drain sampling system with automatic flow containment
Inventor: BACK BRIAN MORRIE
IPC: F16K7/10
Filed: 2009-10-08
Abstract: A system for sampling fluids in a drainage system in low flow conditions comprising an inflatable bladder 4 for deliberately restricting the fluid flow and increasing the depth of a fluid in a pipe so as to increase the height at which sampling is possible. Preferably inflation of the bladder moves a sampling pipe or transducer 5a,5b into the fluid flow. The system preferably comprises a counterbalanced bracket 6 suspended from a pivot 2 which returns the sampling means out of the flow upon deflation of the bladder 4. Preferably, the system may signal an alarm if hazardous substances are detected, and the inflated bladder may also be used to contain the flow within the pipe. The system preferably comprises means 8 to permit sampling at programmable or remotely controllable sampling intervals, and to prevent sampling in high flow periods. The system may be retrofitted within an inspection chamber 1.

Title: Guard for barbeque tongs and kitchen utensils to protect users hand from heat
Inventor: WHICHELOW NEIL ALEXANDER
IPC: A47J37/07
Filed: 2009-10-22
Abstract: A hand guard, particularly for existing barbecue tongs, has a basket-shaped design. It has rectangular apertures A and B in the front and back of the guard through which the hinged end of the tongs is inserted. A larger aperture C is provided in the top of the guard to enable the user to hold the tong's handles. Alternatively, tongs may be manufactured with a built in guard (Fig. 9). The guard makes cooking safer by preventing burns from either hot liquid splashing onto the cook's hand or being burnt by flames from a grill. The guard is more hygienic than a glove and improves handgrip when compared to a glove. It is made from materials of low conductivity (e.g. a silicone compound) and which meet food safety / hygiene standards. A guard may be used with other handheld kitchen utensils including a flipper (Fig 10), spatula, basting brush, spoon, whisk, skewer (Fig 11), or with cookware such as pans with handles. A bottle opener may be built into the base of the guard (Fig. 5).

Title: Improvements in conveyors
IPC: G05D1/02
Filed: 1965-03-10
Abstract: 1,102,202. Conveyer Systems. JERVIS B. WEBB CO. 10 March, 1965 [12 March, 1964], No. 10076/65. Heading B7L. A conveyer system comprises a doublechannel carrier supporting track 10 extending beneath a forward propelling member track 12 and a receiving propelling member track 14 the carriers consisting of a load bar 32 pivotally connected between trolleys 30 and 31, and the propelling members consisting of trolleys 17, 23, provided with pushers 19, 25, connected to endless chains 18, 24. The forward trolleys 30 of the carriers have one-way pivotable driving and hold back dogs 34 and 40, and the rearward trolleys have supplementary driving dogs 42, the dogs 34, 40 and 42 each extending towards the propelling member tracks to a progressively lesser extent. At normal spacing between the track 10 and either track 12 or 14 the pushers overlap dogs 34 and 40, but not dogs 42. To propel a carrier from the forward propelling member to the receiving propelling member a pusher 19 engages a dog 42 at a section of narrow spaced track, between 46 and 48, and just ahead of the position where track 12 laterally diverges from track 10, and propels the carrier towards the receiving propelling members where at wide track spacing a receiving pusher 25 engages and overlaps the dog 34 without fouling the holdback dog 40. This arrangement allows the receiving propelling members to run at a slower rate than the forward propelling members. After a measured distance normal track spacing returns between tracks 10 and 14. Where track 14 laterally converges with track 10, to prevent a receiving pusher laterally striking a dog 34, a plate 64 held only in the path of this dog forces it to be depressed. A carrier stop device, Fig. 3, comprises a plate 66 movable between stopping and non-stopping positions, the plate in the stopping position extending into the path of travel of dogs 34 and 40 below the level of the pushers and causing the dog 34 to depress into a non-driving position while the hold back dog 40 is engaged. A pivoted arm 70 prevents the carrier rebounding. Contact between means 36 and 38 of two adjacent trolleys will cause the dog 34 on the rearward trolley to be disengaged from its pusher 19.

Title: Improvements in or relating to projectiles
IPC: F42C1/14
Filed: 1942-09-16
Abstract: 568,351. Bombs and projectiles. ROST, H. F., and SVENSSON, R. A. Sept. 16, 1942, No. 13058. [Class 9 (i)] A bomb or projectile is exploded at a distance above the ground or away from the target by the aid of a precursory member which is projected from the bomb or projectile after a suitable interval of time and which, after projection, is rigidly coupled with the striker of the firing device. The precursory member 19, which may be continuous as shown or a telescopic axial rod, is provided with an enlarged inner end 25 which has a sliding fit in a fixed central guidetube 6 around which is disposed a spring-driven rotor 4 provided with a priming-cap 5 and a striker-head 13 bearing a striker 9 normally positioned out of line with the cap 5. The rotor is initially locked against rotation by an inertia bolt 2 supported by a withdrawable safety pin 1 and also by a spring stirrup 3, which is deformed on firing by set-back of the piston to release the rotor. The latter is at first prevented from rotation by friction against its seat on the fuze-body 10 due to acceleration. After acceleration has ceased, rotation of the rotor begins and a stop-pin 8 on it releases the end of a lever 22, a wedge-shaped tooth 23 on which normally retains the precursor. A spring 24 within the precursor can then overcome the restraint of the tooth 23 and project the precursor. The rotor moves until stopped with the priming-cap 5 in line with the fixed striker 9 and with a firing-charge 11 leading to the detonator 26. The enlarged end 25 of the precursor pushes back spring studs 17 on the striker head 13 which close again at the rear of the precursor and lock it to the head, so that firing will occur on impact, against the resistance of the spring 14. in the head 13. Other retaining means for the precursor are also described, and it is stated that the precursor may be projected by means of compressed air or an explosive charge, the firing of which may be timed to take place after an interval of time following the discharge of the projectile, or the dropping of an aerial bomb.

Title: Improvements in the manufacture and production of azo-dyestuffs
IPC: C09B43/00
Filed: 1937-04-12
Abstract: Azo dyestuffs are manufactured by saponifying to carboxylic groups the nitrile groups in azo dyestuffs of the general formula <FORM:0493911/IV/1> where R is an alkylene radicle containing at least two methylene groups, X is a hydrogen atom or an alkyl, hydroxyalkyl, aryl or aralkyl group, Y is an aryl group which may be substituted but must not contain sulphonic or carboxylic acid groups, and A is an aryl radicle free from sulphonic and carboxylic acid groups.  The saponification is preferably effected by heating the dyestuffs with acids, e.g. hydrochloric acid, or in alkaline media, e.g. in alcoholic caustic soda solution.  In an example, the dyestuff p-nitraniline --> b -N-hydroxyethyl-N-(3 - methylphenyl) - aminopropionic acid nitrile is heated with 30 per cent hydrochloric acid.  The dyestuff from diazotized 4-aminoazobenzene and the same coupling component may be similarly treated.  The products dye acetate artificial silk red shades. Specification 491,793 is referred to.

Title: Process for the production of pure anhydrous crystalline alkali metal bromides
IPC: C01D3/10
Filed: 1953-04-16
Abstract: <PICT:0730690/III/1> Pure anhydrous finely crystalline alkali metal bromides are produced by a process wherein an anhydrous alkyl bromide, especially methyl bromide, is reacted at a temperature maintained below 50 DEG  C. throughout the reaction with an anhydrous alkali metal hydroxide in an anhydrous liquid which has a substantially lower solvent power for the alkali metal bromide formed than for the corresponding alkali metal hydroxide.  It is preferred to use the alkali metal bromide as a liquid but reaction in the vapour state may be arranged to take place in a column in countercurrent flow to the liquid containing alkali metal hydroxide. Suitable solvents are aliphatic alcohols, ethanol, propanol and butanol being referred to, but methanol is preferred.  The process may be carried out continuously, e.g. in a flow tube or column, and the liquid in the reaction product may be recirculated to the reaction after making up with alkali metal hydroxide.  In the example, sodium hydroxide was stirred into methyl alcohol, and methyl bromide added little by little with cooling.  The temperature first rose to 42 DEG  C., and was kept until the end of the reaction at 20-25 DEG  C.  The sodium bromide was filtered off after two hours and had a purity of 99.5 per cent.  In the apparatus shown, anhydrous medium is mixed with solid alkali metal hydroxide in vessel 13 provided with a stirrer and the solution passed into reaction vessel 1.  This also contains a stirrer to mix the solution with alkyl bromide entering through pipe 7.  The condenser 6 returns condensed vapours to the reaction vessel. Alkali metal bromide is precipitated and falls into conical section 2 from which it can be withdrawn through valve 3 into a sieve centrifuge 9 where it is separated from the liquid, which is returned, together with the anhydrous medium from pipe 18, used as washing liquid, to the reaction vessel.  The process may be worked particularly advantageously in combination with the production of alkyl bromides, e.g. as described in Specification 730,682, [Group IV (b)].
