Title: Improvements in telephone systems
IPC: H04M15/08
Filed: 1925-10-14
Abstract: 264,236. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), and Deakin, G. Oct. 14, 1925. Automatic and semi-automatic exchange systems.-In a system employing two-wire trunk lines a toll operator at the position S is enabled to check the identity of a calling line requiring toll service by means of a check trunk CC over which she gives the number to a switching operator who plugs into the corresponding line jack at the position M. The toll operator also causes an auxiliary trunk JSC to be associated with the trunk WJC over which the calling line reached her by sending impulses thereover from her dial D to control a single co-ordinate switch JS. A circuit is thereby completed from the checking tone transformer CTT over the test circuits of the automatic switches through condensers C1, C2, C3, as shown in Figs. 1, 2, and a tone is heard by both operators. In Fig. 1, the sleeve circuit of the first line of a P.B.X. group is connected through condensers such as CS1, CS2 to the sleeve circuits of the remainder, so that the check tone may be always picked up on the sleeve of the first jack. In Fig. 2, in the case of a P.B.X. line, it is necessary for the switching operator to test the corresponding jacks successively until the check tone is picked up. Specifications 204,176 and 221,869 are referred to.

Title: Improvements relating to cellulose ester compositions
Inventor: FISHER JAMES WOTHERSPOON
IPC: C08L1/14
Filed: 1958-08-13
Abstract: A composition comprises cellulose esterified with acetic acid and with a dicarboxylic acid, under such conditions that one carboxylic group of the dicarboxylic acid remains free, and an epoxy resin. Preferred compositions comprise a major proportion, especially 60-80% by weight, of the mixed cellulose ester and a minor proportion, especially 40-20% by weight, of the epoxy resin. The preferred dicarboxylic acid is phthalic acid, but other acids specified include succinic, maleic and tetrahydrophthalic acids, and the preferred mixed ester contains a major proportion of acetyl groups with a minor proportion of the dicarboxylic acid group.  Desirably the epoxy resin is an epoxy ester resin, especially one made by reacting D 4-tetrahydrophthalic acid or anhydride with a glycol to form a polyester resin and then epoxidizing the polyester resin, e.g. with peracetic acid. Specified glycols include ethylene glycol, 1:2 propylene glycol, dipropylene glycol and triethylene glycol.  The mixed cellulose ester and epoxy resin may be blended together in the absence of a solvent or in the presence of a mutual solvent, especially acetone.  Filaments, films and coatings may be made from the solutions by conventional methods.  On standing or heating such a filament, film or coating the epoxy resin cross-links the cellulose ester thus rendering the composition insoluble. Examples describe the preparation of films by casting acetone solutions of cellulose acetate phthalate-epoxy resin compositions and heating or standing to insolubilize the films.

A lower frame 17 connected by posts 15 with the frame 16 and removable therewith has a number of arms 33 which support a ring 34 carrying a cup-shaped bearing member 35. The spray member spindle 26 has a relatively flexible portion of reduced thickness below its point of connection with the hub 23 of the fan and within the hub sleeve 28, providing for a slight lateral play. The lower end of the spray member carries a bearing ring 32 preferably of water-lubricated bushing material such as lignum vitae, hard rubber or graphite impregnated wood, cushioning rings 39 being provided which permit self alignment of the ring within the bearing member. Liquid is supplied to the base of the casing through a float-controlled valve and may be re-circulated through conditioning apparatus such as a refrigerator (not shown). The liquid inlet pipe is arranged close to an opening 67 in a wall 66 surrounding the bearing member. A perforated pipe is also provided for discharging steam into the liquid when heating is desired. A stopper plate 46 is adapted to close the lower end of the bearing member through the agency of a lever 43 and a rod or cable 50 which may be actuated manually or by means of a humidistat. The spray member 29 may have internal vanes, ribs or pins for ensuring, rotation of liquid drawn in and may widen abruptly or gradually or in stages, lateral arms 54 being similarly formed and terminating in nozzles 56 into which liquid enters tangentially so as to be caused to swirl before ejection through a central outlet 56a. The spray is discharged backwardly with respect to the direction of travel of the nozzles being thereby deprived of momentum. A small hole 71 near the lower end of the conduit 29 allows some of the last portion of liquid to flow back over the bearing ring when the stopper plate 46 is applied, the liquid being continually re-circulated and lubricating the ring whilst the spray is cut off. Unvaporized liquid' is removed from the gas by an eliminator 72 and the hooked upper edges of the arms 19 and the frame 16. A heater 74 is located near the outlet 14. Each inlet 13 may have a sliding door 79 and lower plates to trap outwardly moving spray. The apparatus may be used for dehumidifying air, the spray liquid being repeatedly circulated through a refrigerator.

Title: Improvements in dish washing apparatus
IPC: A47L15/06
Filed: 1950-10-26
Abstract: 688,939. Dishwashing machines. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 26, 1950 [Oct. 29, 1949], No. 26142/50. Class 138 (i). Relates to a door baffle for a dishwashing machine comprising a vat including top and bottom walls and opposed side walls terminating in an upstanding forwardly directed doorway and a gasketless front door therefor, which machine is of the general character of that disclosed in Specification 681,911. As shown in Figs. 2 and 3 a U-shaped flange 46, of an inner body sheet 45 of a door 42, terminates in a marginal rim 47 which engages against a U- shaped vat rib 40, having a top portion and side legs 41, when the door is in its substantially vertical:closed position. Secured to the inner surface of the flange 46 is a U-shaped baffle 72 which is substantially Z-shaped in cross-section as shown in Fig. 6. The wall 74 of the baffle 72 is secured to the flange 46 by welding or the like and the wall 73 which extends beyond the rim 47 is spaced from the flange 46 by the wall 75. When the door 42 is in its closed position the baffle wall 73 passes through the opening afforded by the U-shaped vat rib 40 into the vat. A U-shaped pocket 78 which is U-shaped in cross-section is thus formed between the vat rib 40 and the baffle 72 when the door is closed. When the machine is in operation a turbulence of washing liquid is created in the pocket 78 and this limits admission of liquid past the door into the doorway. Furthermore the close cooperation of door baffles and vat baffles and the tendency of shearing action between the door baffles and vat baffles described in Specification 681,911 is avoided. The machine includes vat venting means 58, 62, Fig. 2, drain mechanism comprising a raisable and lowerable hose, and vat suspension means in the machine cabinet, all as disclosed in Specification 688,849. The door is hinged within the doorway by hinge means 50, as disclosed in Specification 681,912. The sequence of operations of the machine is effected by an automatic electrical timer as disclosed in Specification 681,925.

Title: Materials comprising resin beads impregnated with magnetic powder
IPC: B01J47/016
Filed: 1971-04-19
Abstract: 1337066 Magnetic resin beads PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [8 April 1970 8 Feb 1971] 26177/71 Heading C3R [Also in Division H1] Resin beads contain magnetic particles which are magnetically-aligned and located discretely with respect to each other, i.e. they are not aggregated. The resin may be an ion-exchange polymer; γ-Fe 2 O 3  and BaFe 2 O 4  are specified magnetic particles. The beads may be made by mixing magnetic particles with a polymerizable material, forming the mixture into beads and polymerizing the beads by heat or irradiation, while they are suspended in a liquid. The beads are subjected for a few seconds to an aligning magnetic field at a stage in the polymerization in which the viscosity of the resin is low enough to allow the magnetic particles to rotate but high enough to prevent them from aggregating. The field may be applied by a coil surrounding the container holding the suspended, polymerizing beads, or by passing the suspension through a tube surrounded by a coil. Examples describe the preparation of phenol-formaldehyde beads containing γ-Fe 2 O 3 . In one embodiment, BaFe 2 O 4  or γ-Fe 2 O 3  particles are dispersed in a mixture of polyethylenimine and epichlorohydrin. The product is dispersed in paraffin oil and heated at 90‹ C. for 16 hours to effect polymerization. A magnetic field is applied after 12 hours. In examples, γ-Fe 2 O 3  particles are dispersed in a partially-polymerized phenol-formaldehyde syrup. The product is dispersed in silicone oil containing finelydivided silica and heated for 60 minutes, a magnetic field being applied for various times and after various periods. The beads are isolated by diluting the silicone oil suspension with petroleum ether and filtering.
