Abstract: 1536874 Temporary storage systems in conveyers between cigarette packaging and boxing machines R J REYNOLDS TOBACCO CO 20 Nov 1975 [20 Dec 1974] 47809/75 Heading B8A A temporary storage reservoir 180 in a conveyer system between a cigarette packaging machine and a boxing machine, comprises a magazine 244 which is mounted for vertical movement on posts 194, 196, under the action of a nut and screw drive 198, the conveyer belt 18 between the machine and the boxer passing through open ends of the magazine. Cigarettes packets on the belt 18 overhang the edges of the latter so that as the magazine rises one step, a row of packets is picked up by inwardly projecting pairs of shelf members 266. Similarly on downward movement of the magazine, a row of packets is deposited on the belt. The movement of the magazine is monitored by a photocell 314 (Fig. 19) on the machine frame, which scans holes 318 on a flange 316 carried by the magazine. Other photocells (320), (322), (326), (Fig. 18, not shown) are arranged to scan successively, each pair of shelf members 266 for full or empty occupancy. In the system described (Fig. 1, not shown), there are two packaging machines (10) and (12) feeding through respective conveyers (16) (18) (each having its associated storage reservoir 180 as above-described) to a single boxing machine (14). Flow from the conveyers 16, 18, is distributed selectively to the machine (14) by the action of endless-belt deflector members 510, 512 (Figs. 21 and 22), which can be deflected by respective solenoid units 520, 522 (as shown in broken lines in the case of the member 510). Faulty packets are detected by photocell units in different parts of the system and are discharged by the action of pneumatic jets (Figs. 2-7 and 9-12, not shown).

Title: Method and apparatus for supplying Cops to an Automatic Winding Machine
IPC: B65H67/06
Filed: 1966-10-25
Abstract: 1,165,208. Feeding cops to winding machines. MURATA MACHINERY Ltd. and TOYO BOSEKI. K.K. 25 Oct., 1966 [26 Oct., 1965; 27 Nov., 1965; 8 April, 1966], No. 47853/66. Headings D1F and D1J. A method of automatically supplying fresh cops to travelling winding units of an automatic winder comprises, providing fresh cops of yarn at a given position, transporting the fresh cops in a given sequence along a predetermined path of travel, subjecting each cop to an action to retrieve a free tail end of the yarn, automatically detecting whether the yarn of each cop is in a retrieved condition and detecting a failure to retrieve the yarn end, discharging in succession from the path of travel cops in which the yarn end has not been retrieved, continuing within the sequence to transport along the path of travel as normal cops those cops in which the tail end has been retrieved and transferring the normal cops those cops in which the tail end has been retrieved and transferring the normal cops from the path of travel to the winding units of the automatic winder. The cops are moved along the path in carriers mounted on the periphery of a wheel rotated by the winder during each passage of a winding unit. Stops to prevent movement of a carrier are provided about the wheel at positions adjacent a rotary chute which supplies fresh cops, means to take off the tail end winding, a reserve station, a spindle to rotate the cop and a searcher to remove the back winding, a yarn end retrieval station including a further spindle to rotate the cop, a rotating beater and a suction nozzle, another reserve station, and a failed cop discharging station having a solenoid arranged to open a trap door beneath a cop if a photo-electric detecting device failed to detect a retrieved yarn end. The stops are interconnected and are arranged to be briefly retracted to allow the carriers to be frictionally driven by the wheel to the next stop whenever there is a vacancy for a cop carrier in the reserve positions upstream of the normal cop transferring position. A further stop is provided at the transferring position and is retracted either by the passage of a winding unit or if the next carrier has had a failed cop discharged therefrom. Each cop carrier comprises a pair of cop holding arms which can be opened when a cop is received, is rotated, or is transferred or discharged therefrom. In a modification failed cops are passed through the yarn end retrieval positions a second time and are only discharged if the yarn end has twice failed to be retrieved. Each carrier has a pair of pivoted fingers the positions of which indicate to the cop discharging and transferring positions whether the cop is a normal one or whether the cop has once or twice failed to have the yarn end retrieved.

Title: Mail sorting machine
IPC: B07C3/06
Filed: 1966-10-26
Abstract: 1,126,243. Sorting machines. B. H. BUNN CO. 26 Oct., 1966 [14 Sept., 1966], No. 48130/66. Heading G4M. Envelopes bearing a column of code bits are fed from a stack to a pair of rollers which are inclined to the vertical so as to impart free flight to each envelope, the free flight taking place between a pair of converging guide walls and terminating on a reference surface which serves to align the envelopes with a reading station. On detection of the leading edge of an envelope by a photo-cell, circuit 112 resets flip-flops 107-111 and gates in the code bits from reading photo-cells 97-101. The sorting pockets are divided into groups M1 to M3, each group comprising several pairs of pockets, one pocket on each side of the envelope path. The first bank of flip-flops 107-111 control the solenoid drivers 113-118 for the first group of pockets M1 through decoding AND gates, but should an envelope be destined for a pocket in group M2 or M3, none of drivers 113-118 is actuated, and on arrival at the beginning of group M2, the envelope is detected by a further photocell and circuit 119 transfers the code bits to a second bank of flip-flops 120-124 controlling the solenoid drivers of the second group M2. Similarly, if the envelope is destined for group M3, circuit 132 enables the third group of decoder AND gates on arrival of the envelope at the group M3 to set the appropriate one of power flip-flops 133-138.

A content-addressed memory which allows for search by a variable-length search word comprises a search store 20 into which the search data is loaded in the form of a number of separate search words, a register 12 which receives these search words successively over gates 26 and interrogates the memory matrix 10 in respect of each of them, flip-flops 42, 46 &c. which record the result of the interrogation, and gates 38 which, after each interrogation, transfer the " match " indication downwardly. The number of words forming the search data is recorded in 22 and, when these have all effected interrogation, gates 38 are closed. Fip-flops 42 &c. are reset by mismatch signals so that if and only if a sequence of words in 10 corresponds to the sequence of search words will the flip-flop corresponding to the last word of the sequence in 10 be set at the end of the search.
