Abstract: 837,406. Dosing-apparatus. GILADI, J., RAJZMAN, F., and COHEN, I. Dec. 30, 1958, No. 42082/58. Class 86 A method for keeping constant the concentration of the volatile active ingredient or ingredients of a liquid mixture, e.g. an insecticidal liquid mixture used for treating fruit prior to shipping, comprises bubbling through the mixture a gas inert to the components of the mixture, the inert gas and entrained volatile ingredient being passed to a detector responsive to deviations in the concentration of volatile ingredient in the inert gas, the detector translating the deviations into electric signals which operate means for adding active ingredients to the mixture. As shown, the mixture in the treatment vessel 1 is continuously withdrawn and returned to the vessel through a sampling vessel 2 through pipes 4, 5 and pump 6. The inert gas is circulated in a closed system comprising pipes 10, 13, pump 12 and detector 11. Air, as the inert gas, and ethylene dibromide as the volatile ingredient of an aqueous solution. are referred to. The partial vapour pressure of the active ingredient in the gas above the liquid in the vessel 2 corresponds with the concentration of the ingredient in the mixture being sampled at the moment, and the detector 11 is correspondingly influenced to control, through an electromagnetic valve 9, the admission of active ingredient from the supply tank 7 to the treatment tank 1.

Abstract: 1,247,511. Coated glass container. R. G. DUNLOP. 18 Sept., 1968 [19 Sept., 1967], No. 42657/67. Heading B2E. [Also in Division G5] The interior surface of a transparent or translucent glass container is coated with a polymeric material to simulate contents of the container by introducing an solution of polymeric material which has been mixed with a plasticizer in a vapourisable solvent into the container, rotating the container to cause the solution to flow and form a film coating of the solution over at least part of the interior surface of the container, and removing solvent by passing a gas over the film. Empty bottles may be treated with a coloured material so as to simulate a liquid filling. The polymeric material solution may be dyed or pigmented. The polymeric material may be a methyl methacrylate polymer which may be plasticised with di-butylphthalate, polystyrene. The preferred solvent is methyl methacrylate monomer. In an example for the simulation of a bottle of whisky for display purposes, a solution of a methyl methacrylate polymer with dibutylphthalate plasticiser and methylmethacrylate monomer and coloured by suitable dyestuffs was introduced into a clean dry whisky bottle, a temporary closure fitted and the bottle slowly rotated until the inner surface was uniformly coated. At this stage rotation was stopped, the closure removed and the bottle inverted and a small bore pipe inserted into the neck of the bottle and air drawn over the film by applying a partial vacuum to the pipe until sufficient solvent has been used to provide a satisfactory stable film coating.

Abstract: 932,381. Radiators for heating buildings. IDEAL-STANDARD Ltd. Dec. 15, 1959 [Dec. 15, 1958; Sept. 10, 1959], No. 42658/59. Class 64 (2). A radiator having a number of sections interconnected at their sides has, for restricting the heating of the radiator, a valve 28 for disconnecting one section or passage or more from the rest, to act as a by-pass for the flow of heating medium between an inlet 9 and an outlet 29. The medium from the inlet 9 flows around a tube 10, which interconnects a first section 6 and a third section 8, and flows up a second section 7. When the valve 28 is in the position shown, the medium passes through all the sections to the outlet 29, although there may be a small clearance between the valve and the aperture 19 in which it is shown located, for a leakage of medium directly to the top of the first section 6 to release any gas in the medium. When the valve 28 closes the port 20 in the nipple between sections 7 and 8, the medium flows directly to the top of the first section 6 and the outlet 29. The sections are shown interconnected by nipples 17 having an exterior thread but they may be interconnected by welding or press-fit nipples.

Abstract: 1,271,114. Inoculator gun. O. H. BANKER. 2 Sept., 1969 [6 Sept., 1968], No. 43486/69. Heading ASR. [Also in Division F1] A gun adapted to inoculate a patient by a jet stream without the use of a needle comprises a cylinder 11, a piston 12, a pivotally mounted trigger plate 31 cooperating with an annular abutment 29 on the rod 28 of the piston 12 in order to hold or release it, a source of pressurised gas (19), Fig. 1 (not shown) communicable with one end of the cylinder 11 through a valve (22) and a passage 23, and a pressure sensitive device operating the trigger plate 31 to release the piston 12 when the pressure in the end of the cylinder 11 has reached a predetermined value. The pressure sensitive device includes a shutoff valve 52 and a plunger 47 mounted in the wall of cylinder 11 with a pivoted latch 39, bearing against the end of the plunger 47 and a leaf spring 42 urging the latch 39 against the plunger, the pressure of the spring being manually adjustable by means of a screw. The trigger plate 31 is held in one position by the engagement of abutments 38 and 40 on the plate and latch respectively. In use, gas at 800 p.s.i. is admitted by depressing a trigger (25) thereby opening the valve (22) and admitting gas via the passage 23 and to the valve 52. The gas passes into an annular groove 49 in the plunger 47 into cross-bores 50 and into an axial chamber 51 in the plunger 47 which also contains the three-stage axially movable valve 52, the smallest stage 55 of which acts as a feeler. The feeler 55 is held towards the chamber 51 by the piston 12 during this operation and thus gas is allowed into part of the cylinder 11 which pressure steadily increases until it is large enough to overcome the restoring force of a spring (27) located in the cylinder and enable the piston 12 to move to the left, this pressure also tending to move the plunger to the right. On release, the piston 12 is pushed with a large force to the left to operate a force pump (14) supplied by a vial (15) which forces inoculant out of a nozzle (17) and the valve 52 is pushed also to the left by the gas pressure in chamber 51 to halt the flow of gas from the source (19). When the trigger (25) is released gas is vented from the cylinder 11 through the valve 22. The piston 12 is urged back to its original position by. the spring (27) and the abutment 29 moves on the trigger plate 31 to its original position by engagement with an ear 37. The dosage is variable by selecting gauges (30) Fig. 3 (not shown) located between the abutment 29 and the housing (10). The movement of the trigger plate 31 is limited, after disengagement with the abutment 29, by a ball 62 dragging against a bracket (33).

Each reel 2 has a retainer bar 10, Fig. 4, that holds the starting end of a thread T supplied by a cheese 23. Each reel 2 is driven by a motor 16. Associated with each reel is a guide bar 26 that rocks to a first setting to cause a first hank to be wound on the reel 2, said guide bar then rocking to a second setting to cause a second hank to be wound on the reel.  A counter counts the revolutions of each reel and controls the guide bar 26 via electromagnetic means 29. As the hanks on a reel near completion the counter causes further electro-magnetic means 22 to cause a high speed roller 18, Fig. 8, to disengage, and a low speed roller 20 to engage, a disc 14 driving the reel 2 so as to slow the reel down. When the final revolution of a reel is about to commence the counter causes a further electro-magnetic device 28 to cause a nose 38 on a locking device F to move to a setting in which it can enter a recess 36 in the disc 14. This stops the reel 2 at a predetermined setting relative to a lacing device H, namely a setting in which the two ends of the wound thread T are aligned with the device H.  Lacing device H. The lacing device H includes presser bars 50, 51 Figs. 10(e) that act on the left and right-hand hanks of a reel 2 to form a chevron shape in the hanks between two stays of a reel. A vortex-shaped needle 45 is then rotated anti-clockwise about an axis 44 so as to pass (1) behind the lefthand hank; (2) in front of the right-hand hank; (3) behind the right-hand hank; and (4) in front of the left-hand hank. At this stage a hook 52 on the needle 45 catches the starting end T1 of the thread. The needle 45 then rotates clockwise and thus pulls the starting end T1 in an 8-shape about the hanks as shown in Fig. 10(h). The thread leading to the cheese 23 is then cut and the resulting end T", together with the end T', are sucked down a tube 53 to a knotter I. Doffing. When a reel 2 reaches a doffing station J the arms 8 of the reel move inwardly to release the tension in the hanks.
