Abstract: 1399943 Seaming INDUSTRIE PIRELLI SpA 6 June 1972 [3 July 1971] 26246/72 Heading BSK [Also in Division F2] In the joining of two ends of conveyer, or flat transmission belts longitudinal grooves are formed in a layer of flexible material which forms at least a part of the end of the belt, the grooves in the two ends are aligned, and a cord is fixed in each groove to bridge the ends. The described belt comprises a layer of rubber 1 in which cords 2 are embedded on each side of this there being a layer of rubberized fabric 3 and an outer layer 4, of rubber. Each end is firstly prepared as shown in Fig. 3, with the edge 5 at less than 90 degrees to the side 6, and with the outer layer 4 cut back further than the layer 3. The two ends are then cut to form teeth -14 and gaps 11 of the same width as the teeth, and grooves 16 are cut or formed in the ends of the teeth and the bases of the gaps, these grooves being between the cords 2 of the layer 1. The teeth 14 are fitted together as shown in Fig. 9 after which a length of cord is placed in each groove, the length of two aligned grooves, the grooves are filled in with rubber solution, adhesive (or rubber solution) is spread over the layer 1, rubberized (unvulcanized) fabric is placed so as to extend across between the layers 3 shown, and finally the outer rubber 4 is added (these layers being added to both sides). Finally the join is vulcanized by heat and pressure so that the layers bond together as in the rest of the belt. The invention may be applied to other belt constructions, e.g. where short lengths of cord are embedded in a rubber layer.

Title: Improvements in or relating to means for use in conjunction with the printing mechanism of weighing apparatus for preventing a printing operation being effected except when the apparatus is in equilibrium
IPC: G01G23/18
Filed: 1929-09-04
Abstract: 338,996. Avery, Ltd., W. & T., and Timson, W. Sept. 4, 1929. Printed records, apparatus for giving. - In means for preventing the operation of the printing mechanism of weighing-apparatus unless the apparatus is in equilibrium, the printing lever or the like co-operates with an oscillatory locking means which is mechanically coupled to a dashpot adapted to be influenced by a movement of the weighing mechanism whereby when the apparatus is out of equilibrium the movement transmitted through the dashpot to the locking means causes the locking means to oscillate so as to obstruct, and prevent the actuation of, the printing lever. When a commodity is placed on the scale pan the movement of the mechanism is transmitted through a check arm 12 to the cylinder 10 of a dashpot and causes a displacement of the piston 9, lever 7 and bell-crank lever 4. A projection 3<b> on the printing lever 3 protrudes into the horizontal portion of an inverted T- shaped slot 4a in the bell-crank lever 4 and prevents operation of the printing lever in order to obtain a record, unless the projection is in line with the vertical portion of the slot which position occurs when the weighing mechanism comes to rest. To give greater certainty of action the dashpot 10 is arranged to lag behind the main dashpot of the apparatus. Specification 309,722 is referred to.

Title: A control unit for a digital program-controlled computer
IPC: G06F9/48
Filed: 1962-07-13
Abstract: 1,015,325. Digital computers. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT m.b.H. July 13, 1962 [July 14, 1961], No. 27116/62. Heading G4A. In a computer comprising a plurality of peripheral units, each unit has a bi-stable member for indicating that access is required, setting of any of these members causing the computer programme to be automatically interrupted while the peripheral unit is transferring data. The computer described includes a store 2, an arithmetic unit 3, a control unit 1 and four peripheral input-output magnetic tapes 4-7. The computer word length is 48 bits and the computer operates in the parallel mode. A channel selector 8 scans the indicator flip-flops 28 in the four tape units sequentially. The control unit 1 includes a 16-bit address register 9 and an operation register 10. Data is stored on the peripheral tapes in six parallel tracks. In an instruction for transferring data from one of the peripheral tapes 4, for example, to the computer store, the number of words to be read is entered in a register 11 in the control unit and the first effective store address is entered in a register 14. The " read from tape 4 " operation digits in register 10 are effective via the microprogramming circuit 26 to set a " priority " flip-flop 30 and a " read " flip-flop 29 in the tape circuitry and to store the initial address and the number of words in an index store 13. The computer then continues with other instructions until a buffer register 27 in the circuitry of the tape 4 is filled thereby setting the associated indicator flip-flop 28. When the channel selector 8 senses this set flip-flop, it stops thereby setting a bi-stable circuit 32 which is interrogated at intervals by the microprogramme circuit 26. When the circuit 32 is thus found to be set the current computer programme is interrupted, the contents of the registers 9, 11 and 14 being temporarily transferred into one of two registers 19, 20 associated with the computer storage sections SP1, SP2, this data being re-transferred to the registers 9, 11, 14 when the transfer from the tape 4 has been effected. Circuit details.-The various registers are composed of bi-stable transistor circuit stages actuated in response to computer clock pulses. The wiring of the computer is provided on " crossbar plates " which consist of insulating plates having a set of parallel conductors on one side and a perpendicular set of parallel conductors on the other side, the two sets being connected appropriately at various crosspoints either directly or via resistors or diodes. The microprogramme circuit 26 also consists of such crossbar plates (Figs. 11, 12, not shown).
