Abstract: 1,053,078. Wrapping-machines; endless conveyers. AZIONARIA COSTRUZIONI MACCHINE AUTOMATICHE A.C.M.A. S.p.A. May 5, 1964 [May 7, 1963]. No. 18709/64. Headings B8A and B8C. An article to be wrapped is pushed from a compartmented belt conveyer towards a wrapping station where a plurality of wrappers is folded around it. In the form shown, three wrappers, an outer printed paper, an intermediate cardboard blank, and an inner parchment sheet, are centred by photoelectric devices and cut. They are then carried by a clamp 13 to position B (Fig. 9) on an elevator to which a bar of soap P has been pushed from the toothed conveyer. A yoke terminating in projections is raised around the bar of soap, to centre it and then the yoke is raised further, to clamp the wrappers against a spring-mounted plate 19, at the same time as a rubber-coated platform 16 raises the soap to contact the wrappers. Benders 25 then fold down the sides of the intermediate (cardboard) wrapper until they are practically vertical, when hooks 30 hold them down. The elevator is then further raised so that the end edges are folded by two opposed pairs of fixed blades 31 (Fig. 10, not shown, which is a side view of Fig. 9). Upon arrival at B1 tuckers 32 controlled by a pinion 33 fold under the side edges of the wrapper. As the projections 17 move downwards a transverse bender 36 folds under the lower edges of the wrappers, and when the plate 16 commences its descent, projections 51 co-operating with the benders 36 support the product. The partially wrapped object is then moved horizontally by a comb 53 (Fig. 11, not shown) so that the remaining edges are folded by fixed ploughs. They are then adhered at 58, the adherence being effected by heat sealing if required.

Abstract: 1,250,234. Telephone exchanges. STANDARD TELEPHONES & CABLES Ltd. 5 March, 1969, No. 11785/69. Heading H4K. In an impulse transmitter employing a counter, which is set to the complement of a digit to be transmitted, and an impulse generator which steps the counter to a predetermined count at which further transmission is inhibited, the counter is loaded from shift register. As described the shift register forms part of the code converter described in Specification 1,172,946, and the impulse transmitter is located in a subscribers set which is adapted to respond to voice signals from a disabled subscriber. The voice signals are of Morse Code form and are of variable length. As each bit is received the content of the shift register, which has four bistable circuits, is shifted one step and the new bit ". " or " - " is entered in the first bi-stable. A counter consisting of two bi-stables is incremented by one for each bit. When the end of the code, which is of variable length, is detected (i.e. a long pause is received) the content of the shift register (i.e. the last four bits received) is transferred to a four stage counter and represents the complement of a digit to be transmitted. When any stage of this counter is non-zero a gate is disabled releasing a transistor oscillator causing dialling pulses to be transmitted to line and to the counter. When the counter reaches zero count the gate is again enabled to block the oscillator. Codes which would cause the transmission of pulse groups of more than ten pulses are blocked by gates responsive to particular codes. A further gate controlled by the two bistable counter blocks transmission if a code of other than five bits is received. Recognition by the code converter of these additional codes is necessary as they correspond to switch-hook or in the case of a loudspeaking telephone on/off signals etc. The hook or on/off switch, a dial off normal switch and a dial impulse switch are controlled by transistor amplifiers. A warning lamp is associated with the hook or on/off switch.
