Filed: 1956-02-20
Abstract: 798,491. Igniting burners. BENDIX AVIATION CORPORATION. Feb. 20, 1956 [Feb. 23, 1955], No. 5209/56. Class 75(3) [Also in Group XXVII] A piston type igniter for the combustion chamber 28 of a gas turbine type engine starter comprises a piston 14 for driving fuel from a chamber 12 through a nozzle 17 to a pair of surface electrodes provided by two coaxial conductive members 23, 25 insulated from each other. The inner electrode 23 is formed by the annular end face of a flange 24 on the nozzle and the outer electrode is formed by an annular end face of a flange 26 on an outer conducting shell 1. The outer faces of the electrodes and of a porcelain insulator 27 disposed between the electrodes are flush. The fuel chamber 12 is formed by an inner conducting shell 2 insulated from the outer conducting shell 1 by a nylon shell 3. The nozzle 17 is threaded into a reduced end of the inner shell and forms a conical spray which passes angularly over the electrodes. Fuel is admitted to the nozzle end of the inner shell 2 through a valved port 15, and passes to the nozzle through a spring-closed valve 19 opened by fuel pressure. Pressure air for driving the piston 14 is admitted through a valved port 16 to the end of the inner shell 2, remote from the nozzle. A conductor 9 extending from an ignition box is connected to a stud 6 extending from a conductive plug 4 closing the end remote from the nozzle of the inner shell 2. The outer shell 1 is preferably formed of two separable parts joined by mating flanges 29, 30. The flange 29 also serves to secure the igniter to the combustion chamber 28.

Title: Process of producing aqueous dispersions of organic substances
IPC: C08J3/03
Filed: 1927-03-04
Abstract: 296,685. Anode Rubber Co., Ltd., (Klein, P., and Szegvßri, A.). March 4, 1927. Emulsions, making.-Aqueous dispersions of substances such as vulcanized or unvulcanized rubber, rubber waste, rubber reclaim, rubber substitutes, synthetic resins, balata or gutta percha, or mixtures of such substances, are prepared by bringing the material mechanically into plastic condition and adding successively thereto two reagents forming by mutual reaction a substance facilitating dispersion. Examples of the invention are as follow :-(1) To factis, worked in a masticator until plastic, 5-10 per cent of oleic acid is added with stirring. Ammonia water of about 6 per cent strength is then stirred gradually into the mass to produce the dispersion, which is at first of the water-dispersed type but which suffers a change of phase on further dilution. (2) To 1 kg. of tyre reclaim, rendered plastic in a masticator or between mixing rollers, 60 gms. of commercial oleic acid is gradually added with stirring. 96 gms. of 20 per cent caustic soda are then slowly added followed by 425 c.c. of 6 per cent ammonia water. The dispersion is inverted at this stage and is then diluted with 1.5 litres of 1 per cent ammonia water containing, if desired, dispersing agents or protective colloids. Rubber compounding ingredients, protective colloids or materials such as asphalts, bitumens, mineral rubbers, cellulose esters or viscose may be added to the plastic mass before dispersion. Dispersions of any of the above substances mav serve as the final diluting medium or may be added to the dispersion when completed.

A disposable syringe is assembled from parts which may be stored in a compact package, Figure 6 (not shown), and comprises a flexible, foldable, fluid tight bag 14, an end closure member having a tubular part 16 and a cap part 12 having a nozzle receiving opening and an axially extending wall securable to or integral with part 16 and an elongated tubular nozzle 10 having an end 22 adapted to fit into the opening and at least one discharge port 25, the bag being readily removably attachable to the closure member and the nozzle being readily removably attachable to the cap part. The cap 12 may have a lip 42 co-operating with a circumferential ring 44 on the tubular part 16 to retain the cap 12, the open end of the bag 14 being retained between lip 42 and ring 44 in a fluid-tight manner. The nozzle 10 has a central bore 20 and is secured in the cap 12 by a nozzle retaining sleeve (36) Figure 2, in the centre of the cap which springs over a tapered part (32) of the nozzle and seats around a part (30) of reduced diameter, a rubber gasket 28 providing a seal. The nozzle may alternatively be screwed into the cap, or have a tapered end (72), Figure 4, retained by friction in a tapered socket (74) in the cap. The bag may be retained and sealed on the tubular part by an O-ring (82), Figure 8, clamped between the tubular part and cap, Figure 9, or the tubular part may have a circumferential groove (98), Figure 5, which co-operates with an inwardly extending protrusion (99) on the cap to secure the parts together, the bag being retained between groove and protrusion. The tubular part and cap may alternatively be screwed together or made in one piece with a circumferential groove (81), Figure 7 for retaining an O-ring (79) securing the bag to the tubular part and cap. Alternatively, the cap may be formed with a relatively long tapered part (90), Figures 10, 11, which is used in storage to contain the other parts, the ends being sealed by a plug (92) and a cap(96) with a central cap (93) over a nozzle receiving part of cap (96). The nozzle may be in two parts (94, 95). The bag is secured and sealed on the tapered part (90) by a tubular clamping part (91). All the components may be made from polyethylene or polypropylene. A packet of powder for mixing with the fluid dispensed may be included in the sealed package.
Patent GB-791058-A (GB)
Title: Container filling machine
Inventor: KNOBEL MAX
IPC: B65B1/46
Filed: 1955-03-02
Abstract: 791,058. Filling containers. PNEUMATIC SCALE CORPORATION, Ltd. March 2, 1955 No. 6216/55. Class 94(1). [Also in Groups XXXV and XL(b)] A container filling machine deposits formed loads of granular material in containers and has means for agitating the containers to settle the load, the degree of agitation being dependent on the density of the load. The loads are formed in measuring chamber, the volume of which is adjustable according to load density as determined by a check weighing. The machine comprises a continuously rotating disc 18 having a side wall 20 and a series of measuring chambers 14, the disc rotating beneath a non-rotating hopper 10 so that chambers 14 are filled as they pass through the hopper and their loads are levelled off as they leave it. Each chamber 14 comprises and telescopes into a sleeve 28 carried on a rotating disc 30, the base of each sleeve being closed by a shutter 36. The shutters 36 are swung aside by cam means 44 to discharge the loads into containers 60, continuously moving with the chambers and carried on a conveyer 76, and in the case of one load, into the receptacle 68 of weighing apparatus 70 (see Group XVIII). The weighing apparatus controls means varying the volume of the chambers 14 by raising or lowering the disc 18 and parts 16 of the chambers 14 relative to the sleeves 28. The weigh beam comprises means 142, Fig. 11 (not shown), which obstructs a jet of air in proportion to its deflection, the consequent pressure variations operating switches controlling a motor which varies or lowers the disc 18. The motor rotates one of a series of screws 200, linked by a chain 204 and passing through a ring 26 to raise or lower it, the ring carrying rollers 24 engaging the wall 20. If the check weigh reveals a light load, the disc 18 is raised to increase the volume of the chambers 14, and vice-versa. The unweighed loads pass through funnels 62, rotating with the chambers, into the cartons 60 while the weighed load, after being discharged to a receptacle 72, is released by a cam 416 opening a hopper door 412. The filled cartons pass along a rail 501 which is reciprocated vertically to settle the loads, the reciprocation being controlled by the load density. In one mode of control, the rail is operated by a beam 506 raised and lowered by a rotating cam 508, the beam being raised to a greater or lesser extent clear of the cam 508 by a further cam 514. The cam 514 is automatically adjusted through a gear train by rotation of the screws 200 to vary the volume of the containers 14. In another embodiment, Fig. 27 (not shown), the screws 200 cause a contact to traverse a variable voltage transformer controlling a magnetic device agitating the rail. In another, Fig. 28 (not shown), the screws 200 control a valve admitting air to a pneumatic motor operating the rail. In a still further variation, the settling is independent of the adjustment of the measuring chambers and is controlled by photo-electric means (see Group XL(b)) responsive to variations in level of the material in the containers.
