Abstract: 321,266. Callender's Cable & Construction Co., Ltd., and Wilson, A. E. Sept. 3, 1928. Direct connections between conductors; fusible cut-outs. - A device for retaining a metal strip, such as a fuse, in electrical connection with a rigid contact, consists of a spring plunger across a flat face of which the strip is secured, the plunger then being inserted in a flat-sided recess in the rigid contact. A bent strip 1 forms a plunger to the face 5 of which. a strip 3 is attached by bending the end of the strip round the edge of the face 5, the plunger being then inserted in a recess 8 in the rigid contact 2. A bevelled or bent surface 22 coacts with a neck cut in the strip 3 to locate the strip and prevent it from cracking when bent. A projection 10 prevents upward movement of the strip, and projections 9 prevent excessive bending of the strip forming the plunger. The plunger is bolted to a bridge carrier 15 and fits into a recess 19 therein, a tongue 21 entering a recess to position the plunger.

Title: Production of rods, tubes and the like from polytetrafluorethylene
Inventor: DEAKIN STANLEY THOMAS
IPC: B29C48/09
Filed: 1948-10-01
Abstract: 656,300. Moulding polytetrafluorethylene. BRITISH MECHANICAL PRODUCTIONS, Ltd. Oct. 1, 1948, No. 25684. [Class 87 (ii)] Rods, tubes and like elongated articles are produced by preparing a polytetrafluorethylene pellet of rod or tube-like form by compacting the material in powdered, granulated or flocculent form, sintering the compacted material at above 327 C., and then extruding the pellet to decrease its cross-sectional dimension with a corresponding increase in length, To avoid disintegration of the pellet, the reduction in cross-sectional dimension may be limited to one-half. The extrusion may be carried out at a temperature below that at which the material becomes substantially elastic, e.g. normal atmospheric temperature, or at a temperature higher than that at which the material becomes elastic, in which latter case the material is constrained in the extruded form during cooling. The articles produced by the invention are under internal stress, and by releasing this stress they can be restored in part to the original shape of the pellet. The release may be effected successively along the length of the article, to produce in effect one or more local increases in cross-section dimension. The release may be effected by heating or by mechanical means such as shock, vibration or bending. The drawing shows an apparatus for extruding tubes, comprising a body 1 having a socket 2 in which the pellet is placed, a bottom die 3 having a bore 4 into which the pellet is to be extruded, and a top tool 5 which carries a plunger 6 and mandrel 7. The plunger and mandrel are removably held in the tool by a spring-pressed pin 8 which is forced inwardly by a ramp 9 as the body and tool are brought together. In use, a succession of pellets are placed in socket 2, the mandrel 7 is pushed through them, and the pellets are successively extruded into bore 4 by pressure of plunger 6 on the uppermost pellet. To extract the tube, the top tool is removed, carrying with it the mandrel and tube, the pin 8 releases the mandrel, the mandrel is withdrawn carrying the tube, and the tube is removed from the mandrel. Specification 592,127 is referred to.

An envelope addressing system includes apparatus for producing master cards, each bearing an address, apparatus for transferring the addresses on to a master type and apparatus for printing the addresses from the tape on to successively fed envelopes. The cards are produced from a web 101, Fig. 1, which is fed from a roll 100 through a tank 130 in which the web is impregnated with a vaporizable sensitizer to a printing mechanism 140 and a cutting mechanism 150. Each card is then fed to a vaporization station 10, Fig. 3, where an infra-red heating source 241 causes vaporization and condensation of the sensitizer on the card in the imaged areas such that a latent image is produced on an intermittently movable tape 200 of the appropriate address. The latent image is developed in a tower bath 250 and the tower is partially fused by an infra-red heater 253. Envelopes 330, Fig. 7, are addressed by passing them in superimposed relation with the image bearing tape through a heating and pressing station 310. If desired, the imaged tape 200 may be cut into address sections, each section being stuck to an envelope.
Patent GB-258874-A (GB)
Abstract: 258,874. British Celanese, Ltd., (Assignees of Dreyfus, C., and Platt, H.). Sept. 22, 1925, [Convention date]. Yarns and threads, treating with liquids.-By treating fibres, yarns, woven or knitted fabrics of cellulose acetate, or other organic esters of cellulose, or ethers of cellulose with tin chloride and thereafter fixing the tin in an insoluble form on the fibre, an increase in weight and volume, a reduction in inflammability and " laddering " in the case of knitted fabrics and the avoidance of a tendency to melt under a too hot iron are obtained. This effect increases with the duration and temperature of the tin chloride treatment, and the fixing may be done by di-sodium hydrogen phosphate or sodium silicate, or by both in succession. Tannic acid may also be used for fixing. Instead of tin chloride other metal salts having a swelling action, such as zinc chloride may be used, and swelling agents may be used with other metal salts such as aluminium chloride, ferric chloride and chromium chloride, which are not swelling agents.

Title: Dish washer
IPC: A47L15/23
Filed: 1949-10-12
Abstract: 670,679. Dishwashing machines. ORNAS, E. H. AF. Oct, 12, 1949 [Oct. 14, 1948], No. 26176/49. Class 138 (i). In a dishwasher of the kind having a pump for delivering washing liquid from a container to sprays in a washing chamber and having means for controlling the washing process arranged in a vessel for rinsing liquid, heating elements are arranged in the container and vessel and are' brought into operation automatically together with the pump, when the vessel has been filled with rinsing water, and means are provided to subsequently interrupt the washing process, disconnect the heating elements and to operate a device for spraying rinsing water in the chamber, which device is automatically disconnected when the rinsing operation is completed. Water is tapped into the washing liquid container 3 having an overflow cock 14 and connected by pipes having cocks 5 and 6 to the rinsing liquid vessel 4, the cock 5 being arranged at the same level as the cock 14. When the container and vessel have filled the cocks 5, 6, 14 are closed and floats 16, 17 in the vessel 4 are in their highest positions and actuate bellows 24, 23, respectively, the former being contracted and the latter extended. The bellows 23 then actuates a mercury switch 23a to energise electric heaters 11, 18 in the container and vessel, respectively, and also the motor of the pump 7 so that washing liquid is sprayed over dishes in the washing chamber 2 by upper and lower rotatable spray arms 9. The heaters are so arranged that the washing liquid attains a suitable working temperature when the rinsing water boils. Steam pressure in the vessel 4 then passes rinsing water through a siphon 19a to a pump 19 and the float 17 sinks to break switch 23a to de-energise the heaters 11, 18 and pump 7 and to start the motor of the pump 19 so that the dishes are sprayed with rinsing water from a pipe 21 at a temperature of about 100‹ C. When the greater part of the rinsing water is pumped out of the vessel 4, the lower float 16 actuates a switch 24a to stop the pump 19 so that the machine ceases to function. In the meantime all the rinsing liquid pumped to the washing chamber 2 has flowed through a detachable screen 13 into the container 3 and the level therein rises to such an extent that a siphon 15 therein empties the container. A main switch 22 first closes the electric circuit of the machine which then operates as described above. The pumps 7 and 19 may be driven by a common reversible motor, one pump then being driven when the motor drives in one direction whilst the other pump is driven when the motor drives in, the opposite direction. In this case the switch 23a would be used to change the direction of rotation of the common motor. The electric heating elements may be replaced by gas burners or other suitable sources of heat.
