Patent GB-405368-A (GB)
Title: A process and apparatus for softening water
IPC: C02F5/02
Filed: 1932-09-03
Abstract: 405,368. Softening water. CHEMISCHE FABRIK BUDENHEIM AKT.-GES., Mainz, Germany. Sept. 3, 1932, No. 24586. Convention date, Sept. 3, 1931. [Class 46.] In softening water by treatment with alkali phosphate the precipitation of the hardening constituents is caused to take place in a non- heated pipe system, preferably provided with windings and bands, through which the water is passed at such speed that turbulent currents and eddies are formed. The pipe system may be provided with one or more constrictions, which may, if desired, be capable of regulation. With the apparatus shown in Fig. 1, crude water supplied through the pipe b is heated in the cascade heater by steam supplied from the boiler m through the pipe c and mixed with alkaline blow-down water supplied through the pipe d. The alkaline reagent reacts with the hardening constituents in the water as the latter passes through the first portion of a pipe system f, and softening is completed in the later portion by a solution of alkali phosphate supplied through a funnel h from a tank g. The water is then passed through a filter i and is subsequently supplied to the boiler from a collecting box k by a pump l. In modified apparatus the pipe system is under a pressure corresponding to that of the boiler. The crude water and the blow-down water are delivered by separate pumps to a pipe which is fitted with a mixing nozzle receiving steam from the boiler. The alkali phosphate is delivered to the pipe system by a third pump.
Patent GB-247625-A (GB)
Title: Improvements in apparatus for wrapping-up or packing loaves of bread and the like
IPC: B65B11/22
Filed: 1924-10-17
Abstract: 247,625. Lord, J., and Harwood, J. R. Oct. 17, 1924. Packeting by wrapping. - In a machine for wrapping loaves of bread &c. in waxed paper, each loaf is carried by a continuously or intermittently moving belt 2, Figs. 1 and 9, until it rests upon a pair of sliding plates 17 which then move aside and allow the loaf to fall upon a vertically reciprocating table 18 against which a wrapper b is gripped by spring-pressed automatically-actuated grippers 221, Figs. 9 and 15. The table 18 descends thus turning the wrapper against one side of the loaf as shown in Fig. 2. and a bar 24 carried by an arm 25 fixed to a shaft 26 mounted on the table 18, then swings round the loaf and turns the wrapper over its top and against the other side, as shown in Fig. 3. The arm 25 turns in one direction only and is caused by a rack 28 and pinion 27 to make one complete revolution during each descent of the table 18. As soon as the table reaches its lowest position, folding-plates 32 carried by arms 33 turn the top edges of the wrapper down over the ends of the loaf. Sliding plates 37, Figs, 4, and 9, operated by levers 38, fold in the projecting ends on one side, and a pusher moving in the same direction as the plates 37 then pushes the loaf off the table 18 on to a travelling belt 46. During this movement, the fixed plates 47 fold in the other sides of the wrapper against the ends of the loaf, and the depending side of the wrapper is at the same time turned in under the loaf by a plate 48. The projecting flaps b', Fig. 4, are finally turned, in known manner, either under the loaf or up against the ends by the splayed portions of the plates 47. Projections 49, Fig. 4, on the belt 46 carry the loaf past an electric or other heater 51, which melts the wax of the final folds, and then past a water-cooled chilling-device 52 to an incline 53<a> which discharges the loaf from the machine. The wrapping-paper is drawn from a roll h and is fed into correct position over the table 23, Figs. 1 and 2, by positively driven rollers 53, 54, Fig. 9, and the correct length is then cut off by a blade 55 mounted on slides 56 operated by the levers 38. The grippers 221, Fig. 15, are operated in one direction by a spring 61 and tappet 59 contacting with a fixed part 58, Fig. 9, of the machine when the table 18 reaches its highest position, and in the other direction by a tappet 22<a> which contacts with a fixed part 22<b> when the table 18 approaches its lowest position, a spring catch 60 holding the gripper open during the subsequent ascent of the table. According to the Provisional Specification, the plates 17 may descend vertically prior to their withdrawal to deposit the loaf on the table 18, and a rack on the vertically moving carrier for these plates may operate the feeding-device for the paper. It is also stated that the wrapping arm may rise vertically through a slot in the table, pass over the top of the loaf. and then descend through another slot, thus causing the wrapper to encircle the loaf.

[Also in Division B4] A method of making a rotary cutting, scoring, creasing or perforating die comprises making radial incisions 11 in a curved base-plate 10 carried by a cylinder, and then inserting into the incisions a steel cutting &c. rule 12 having a serrated rear edge. As shown, the insertion of the rule has been effected as far as the point 13. The incisions may be made by a saw or by heat treatment of the base-plate. Insertion of the rule may be effected by driving in, pressing in or by rolling. After insertion of the rule, the gaps remaining between the teeth and the cutting rule may be closed by heat treatment of the base-plate or by means of adhesive. The cutting rule may, alternatively or additionally, be coated with adhesive before or during insertion. If the teeth of the cutting rule are provided with barbs, these are sufficient to hold the rule to the base-plate. The base-plate may consist of a metal e.g. aluminium, brass or steel, a thermoplastic material e.g. hard PVC or a thermosetting plastics material.
