Title: Improvements in or relating to accounting machines
IPC: G06K7/08
Filed: 1955-11-02
Abstract: 783,586. Statistical apparatus; calculating- apparatus. EXACTA BUROMASCHINEN GES. Nov. 2, 1955 [Nov. 2, 1954], No. 31392/55. Class 106 (1). A key-set accounting-machine has means for reading and printing an Old Balance magnetically recorded on an account card inserted in the machine. The account card 1 has a magnetic track a which may be sprayed or printed on the card or in the form of a portion of magnetic tape secured to the card. On this track are recorded in series the digits of an Old Balance in the form of sections of different frequencies. As the card is fed into the machine, these sections are read in turn by a head 4, the signal being passed through one channel of an amplifier 5 to filters 6 corresponding to the ten digit frequencies. As a digit is read, the corresponding filter causes operation of an associated relay circuit, Fig. 2 (not shown), to energize a corresponding magnetic device 8 which controls the setting of a type-bar 9. When all of the type bars 9 have been set, a printing roller 10 is actuated. The digits of the Old Balance are erased from the track a by a head 11 after they have been read. An entry is then effected by means of the keyboard, after which the New Balance is printed. Before the type-bars 9 are restored after printing this balance, the card 1 is fed out of the machine and a switch 12 is driven synchronously with the card so as to apply potential in turn to switches 16 positioned with the type bars. The switches 16 are connected to generators 14, Fig. 3 (not shown), each of which generates one of the digit frequencies when energized. The generators are connected by a common lead 20, and through a second channel of the amplifier 5, to the head 4 so that the digits of the New Balance are recorded serially on the track a. A second track b on the card may carry a similar magnetic record representing the printing line reached on the card to enable the latter to be automatically positioned when next fed into the machine. A further track may bear a magnetic record of constant matter, e.g. an account number, or other distinguishing mark.

Abstract: 1,214,738. Moulding shoes. RIEKER & CO. 5 July, 1968 [16 Dec., 1967], No. 32313/68. Heading B5A. Shoes of several different successive foot sizes are produced using an apparatus comprising an outer mould formed of two parts 1 and 2 and having fixed inner cavity dimensions and a core 3 within said cavity having outer dimensions the same as the shoe size to be produced. The core 3 is surrounded by a moulding cover 5 attached to the core 3 by elastic bands 4, the cover 5 being inflatable (shown in inflated position in Fig. 2). In use the outer side of the cover 5 is applied upon a lining bag 10, for example of leather, which is of a general shape similar to the core 3 and corresponds to the inner shape and dimensions of the boot to be made. This lining bag 10 is secured at points 11 to reinforcing layers 12 and 13. The cover 5 is then inflated, so expanding the lining bag and pressing it firmly against the reinforcing layers. Moulding material is injected into the space between the outer mould and the cover 5, lining bag 10 and layers 12 and 13 to form the outer layer 6 of the upper and the outer sole. The pressure in cover 5 is then reduced so that it and the lining bag 10 are drawn back on to the core 3 by the elastic bands 4, leaving chambers 8<SP>1</SP> and 811 between the lining bag 10 plus the core 3 and the outer layer of the upper which are then filled with moulding material by injection to form filler layers. The size of the total core is varied by inflating the cover 5 to different extents. Two solid cores of different sizes may be used instead of a core and moulding cover. The moulding material used is plastics material or rubber. A vacuum instead of elastic bands may be used to draw the cover 5 back on to the core 3.
