Patent GB-343152-A (GB)
Abstract: 343,152. Checking receipts &c. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Shipley, B. M.; 2021, Catalpa Drive, Dayton, Ohio, U.S.A.) Nov. 15, 1929, No. 34901. Convention date, Dec. 19, 1928. [Class 106 (i).] Cash registers ; transfer-mechanism.-Whenever the capacity of a normal totalizer in a cash or other accounting machine is exceeded, one is added to a step-by-step counter. Such a counter may be provided for each of a number of totalizers, and in the particular example shown there may be one for a selected totalizer in each line. As usual in machines of the Shipley type, the back line totalizer 70 is moved into and out of engagement with the actuators by the rocking of the shaft 76 secured to which is an arm 126 carrying a pin engaging a cam slot 129 in a bell-crank lever 128. The other arm of this lever has a pin 131 engaging an L-shaped slot 132 in a link 133 connected with the actuating pawl of an ordinary counter mounted on the keyboard. At each operation of the machine the bellcrank lever is rocked but normally fails to operate the link owing to the pin occupying the longitudinal portion of the slot, the link being held up at this time by a latch 147 engaging a shed 145, Fig. 7. When the capacity of the totalizer is exceeded, however, this latch is tripped by a " transfer tooth on a wheel rigid with the highest totalizer wheel so that the link 133 descends to the position shown in Fig. 8, wherein the rocking of the lever 128 will be effective to shift the link to the right and so operate the counter. The link is restored to normal latched position in the next operation of the machine by a slotted link connection with the indicator-aligning mechanism. Specification 218,689, [Class 106 (i), Calculating &c.], is referred to.

In each flat of a block three fans 16 blow air over three heat exchangers of different heat output and resistances are arranged in the fan motor circuits in such manner that the electricity consumption recorded by a meter 17 is proportional to the heat output of the heat exchangers and may thus be used as a basis for the heating charge levied on the flat. As illustrated, the fan motors of the heat exchangers having the higher outputs are shunted by resistances 19 and 20 whose values are such that the electricity consumed in each fan circuit is proportional to the output of the associated heat exchanger. Each fan circuit may be provided with a solenoid switch or a thermal switch, Figs. 3 and 4 (not shown), in such manner that if the resistance 19 or 20 burns out, the associated fan is rendered inoperative. The heat exchangers are basically identical but are adapted to have different heat outputs by the inclusion of baffles (15), Fig. 1 (not shown), which blank off air flow from portions of the heat exchangers. In another embodiment, Fig. 5 (not shown), the heat exchangers are identical, but have different outputs by virtue of resistances connected in series with the fan motors to reduce the speed of the latter.

Abstract: 522,040. Abrasive articles ; flexible abrasive sheet material. TENNANT, W. J. (Carborundum Co.). Dec. 3, 1938, No. 35292. [Class 60] [Also in Groups V and IV] Bonded abrasive articles are formed with a supporting or reinforcing material of fibrous glass in the form of woven or felted fabric, yarn or individual fibres. Glass fabric may be embedded as a reinforcement in a bonded abrasive body, e.g., an abrasive wheel ring may comprise layers of the fabric with the bonded abrasive therebetween, or glass fabric may be secured to a bonded abrasive body as a backing, or the fabric may be used as a flexible body to which a coating of abrasive particles is attached by means of a bonding-material. Glass threads or yarn usually in an amount approximately 2 per cent. of the weight of the abrasive grain may be distributed in a bonded abrasive body. Binders specified are resins, e.g., phenol formaldehyde resins, rubber, and ceramic binders such as sodium silicate or the calcium aluminium silicate as described in U.S.A. Specification 2,138,829. In the production of abrasive articles employing a glass fabric and a resin binder the fabric may be impregnated with a mixture of liquid and powdered resin or with rubber. When a ceramic binder is used, the fabric is preferably first treated to remove any wax or grease. In employing glass threads or yarns balling during mixing with phenolaldehyde resins and abrasive is prevented by coating the fibres with an aqueous solution of polyvinyl alcohol or with liquid resin.

Title: Precision forging method and apparatus
IPC: B21J9/08
Filed: 1956-11-20
Abstract: 851,407. Forging. CAVANAGH, D. A. Nov. 20, 1956 [Nov. 22, 1955], No. 35412/56. Class 83 (4). A method of precision forging a workpiece 19 comprises electrically heating a portion of the workpiece by passing an electric current through it and simultaneously applying thereto a predetermined pressure such that the workpiece is upset when the correct forging temperature has been reached, and then forging the upset portion to its desired shape by applying a higher pressure thereto. In an electric upsetting process, metal bar stock 19, which may be fed automatically, is held between the two halves 16, 17, Fig. 4, of a die 12 which are closed by bolts or hydraulic means. The ends of the bar are held respectively against a fixed abutment 11 and a movable anvil electrode 22; a brush 29 biased by a spring 30 or by hydraulic means forms the other electrode and may be housed in or separate from the die 12. In operation, hydraulic fluid from a reservoir 35, Fig. 2, is supplied by a pump 33 through a reversing valve 36 to a cylinder 24 whose piston 23 applies a predetermined pressure P1 to the anvil 22. Simultaneously a switch 27 is closed whereby the portion Db of the bar is heated by alternating current from a source 25. When the correct forging temperature, e.g. 2000‹ F., is reached the bar is upset under the pressure P1 and simultaneously the die is moved towards abutment 11 by hydraulic motors 15 supplied with hydraulic fluid through reducing valve 37. Finally the die 12 engages a control device 39 which opens both switch 27 and a valve 40 whereby addition pressure from a second pump 34 is supplied to cylinder 24, thereby causing anvil 22 to force the upset end to conform with the shape of the die cavity, Fig. 6 (not shown). In another embodiment, Fig. 8 (not shown), the brush 29 may comprise three segments which together completely surround the bar and are pressed radially inwardly by hydraulic motors.

[Also in Groups XXIII and XXVIII] A balsa wood batten or sheet formed with interrupted or blocked grooves 13 parallel to the grain in one face or two opposed faces is used for thermal and acoustic insulation as a structure built up of two or more superimposed layers glued together and having, particularly if thermal insulation is especially desired, interposed thin sheets of insulating material such as brown paper, balsa, synthetic plastic or metal. The grooved battens or sheets may be enlarged by pulling them to open up the grooves and by inserting spacers, such as the comb 26, of wood, synthetic plastic or laminated material, into the grooves to maintain them in this condition. The combs block the grooves and prevent circulating convection currents from being set up in individual grooves but this may also be prevented by decreasing the depth of the grooves, preferably to zero, at intervals along their lengths or by filling the grooves with balsa wood dust, or a powdered synthetic plastic or mineral material, and binding the material in the grooves by spraying the surface with cellulose acetate or sodium silicate. The layers may be arranged with grooves running either parallel or mutually perpendicular to each other in adjacent layers and the two outer layers may be ungrooved on their outer faces. Panels may be glued side byside with a plain butt joint or with a zig-zag joint strengthened by a dowel running into both panels at an angle across the joint. For thermal insulation, a structure comprising one or more layers may be glued or otherwise secured to the external surface of a tank, pipeline or refrigeration space or it may be used as an internal lining and, if fluid is to be stored and the balsa wood itself is insufficiently impermeable, an inner caul of plastic material or thin metal sheet may be provided.
