Title: Method for producing a hermetically sealed package
IPC: B65B9/213
Filed: 1964-12-31
Abstract: 1,049,610. Packaging in lined boxes. DIAMOND INTERNATIONAL CORPORATION.. Dec. 31, 1964 [Feb. 5, 1964], No. 53001/64. Heading B8C. Sleeving 328 (Fig. 21) to form the lining of a box 12<SP>1</SP> is held in shape while it is inserted in the box and is subsequently cut and sealed so that the seal 318 forms the bottom of the next lining. The shape of the sleeve may be maintained by guides 334, and compressed air may be blown into the sleeve or alternatively the sleeve may be filled with material as it is inserted in the box: to this end the guides 334 may be replaced by a filling nozzle. Alternatively the guides 334 may be replaced by a rigid sleeve which rests on the top edges of the box and through which the lining sleeve is fed. The guides 334, or other supports for the lining sleeve, may be retracted when the seal is to be made, or alternatively the box 12<SP>1</SP> may be drawn downwardly away from the guides. In another form (Figs. 11 and 12, not shown) the box 112<SP>1</SP> is raised into engagement with members 135 on an external support 134 for the lining sleeve and the box and support 134 are then moved upwardly together, so that the lining, sleeve enters the box, and the support 134 is then raised further, to permit seals to be made at 122, 126 for the top of one liner 128 and the bottom of the next. The box, support 134, and sealing jaws 122, 126 are then lowered together to draw the lining tube downwardly and the lining tube is cut by a guillotine 132 so that the filled and lined box 112<SP>1</SP> may be replaced by a further empty box to permit a fresh cycle. The boxes may be fed to the machine on a conveyer 10. The tube may be formed by longitudinal seaming.

Title: Circuit arrangement employing a memory with random access
IPC: G09G1/16
Filed: 1974-12-09
Abstract: 1496148 Digital data storage HARTMANN & BRAUN AG 9 Dec 1974 [19 Jan 1974] 53182/74 Heading G4A A randomly accessible memory SP for use as an image repetition memory in a data display device has values MW sequentially stored therein by means of an address counter AZ incremented by clock pulses TJ, writing addresses SA being fed from the address counter AZ to the memory during a writing cycle, one of the (in general) chronologically older values stored in the memory being read out first at the start of a subsequent sequential reading cycle. This is achieved in effect by adding 1 to the last-used writing address SA (to produce the chronologically newest address) and then adding a relative interrogation address AFA to the sum, the actual additions being carried out in a different order by adder stages AS and KA. The resulting reading address LA is then fed to the memory to access the corresponding stored value.

Title: Simulation system
IPC: H04M3/32
Filed: 1974-12-10
Abstract: 1468988 Simulation INTERNATIONAL STANDARD ELECTRIC CORP 10 Dec 1974 [28 Dec 1973] 53353/74 Heading G4A [Also in Division H4] A data processing system includes a system computer CPa programmed to control a telecommunications switching network SN, a simulation computer CPd arranged to simulate the activity of the network under a traffic load, and an interface between the computers, the arrangement being such that when the time of occurrence of an event has to be determined the system computer is programmed to halt and the simulation computer is programmed to record the time of the halt, halt instructions being provided in the system computer program for at least some of the events at points where a halt would not be made if the system computer were controlling the network SN. The duration of a program, e.g. a program which searches for a free path in network SN, is measured by replacing the first instruction of the program and the first instruction following the program by multiple execute instructions see Specification 1,301,417 each of which controls the execution of a halt instruction and the replaced instruction of the program. A stop detector DS detects the halt instruction to produce signal AR to reset MA and block gate pt. The system computer CPa operates in response to clock pulses supplied via gate pt and is thus stopped. A counter C1G, repeatedly decremented to zero by the clock pulses, records the actual operating time of CPa (as opposed to time spent monitoring and timing the operation of CPa &c.) the signal ZRT serving to indicate that the counter contents have been decremented to zero, to reset flip-flop MA to block gate pt and thus stop CPa and the counter C1G, to increment a field in memory M to update an elapsed-time record, and to reload counter C1G, and to set flip-flop MA. In response to the detection of the halt the current elapsed time record in memory M is copied into a further memory field, the contents of counter C1G are read, and thus the start time of the path search program is calculated. Flip-flop MA is then set to restart computer CPa, which then executes the path search program, and to restart counter C1G. Any input/output instructions in the program are detected at DT to stop computer CPa and record their time of occurrence as above. Following execution of the last instruction of the path search program a further multiple execute instruction including a halt instruction and the first instruction following the program is executed to record, in the same way as above, the end time of the program. Thus by subtraction the actual duration of the program may be established and printed. During simulation computer CPa operates on data in memory M simulating the activity of the switching network rather than on the network itself.

Abstract: 1,256,362. Telephone exchanges etc.; substation apparatus; mouthpiece attachments. PHOTO MAGNETIC SYSTEMS Inc. 26 Nov., 1968 [4 Dec., 1967], No. 55972/68. Headings H4J and H4K. [Also in Division G4] In a system in which a computer may be accessed over a telephone network from a plurality of sub-stations, the computer is provided with a translator 40 which translates V.F. signals sent by a keysender at a sub-station 30 into signals representing alpha, numerical or control data which are suitable for operating the computer. The system is basically that described in Specification 1,156,899 but gives details of a relay contact-tree logic (Figs. 4, 5, 9, 10, not shown) which is suitable for translating the incoming V.F. signals. The method of sending alpha-numeric data involving 36 or more different characters from a ten-key V.F. sender 32 (Fig. 2) is most readily appreciated from a consideration of Fig. 8. For example, the letter A is sent by initially operating simultaneously keys 2, 3 thus sending the single frequency A1 which is interpreted by the translator as a function command indicating that the next digit or digits will be alpha 1 characters c.f. Alpha 1 shift in Fig. 8. Thereafter key 2 is operated so as to send the two frequencies A1, B2 which will be interpreted as the alpha character A. The letter B would be sent by shifting to an Alpha 2 mode (i.e. depressing keys 5, 6) and then operating key 2. Other characters are sent in a similar manner. As an alternative to the above method, letters may be sent by using a single alpha shift signal followed by two successive multi-frequency signals. For the letter A for example the two successive signals would be obtained by pressing key 2 (indicating the ABC group) and then key 1 (indicating the first letter of this group). The computer described is a card punch unit whose punch magnets 50 and punch clutch 54 are actuated, inhibited and delayed by contacts in the translating logic 40 is exactly the same way as if they were under the control of their normal keyboard 48. It is suggested that the keysender may be attached to a normal rotary dial set for use after the latter has initiated the call. As an alternative, a card-reading autodialler may be used since the sensors therein for detecting holes in the card are functionally equivalent to keys. Various tones are reverted to the sub-station indicating the progress of the processing operation. Sub-station incorporates a mouthpiece attachment (Fig. 1, not shown) that comprises a plastics cup which is a push-fit on the mouthpiece of the handset associated with the keysender. The attachment is utilized so as to prevent any audio interference with data sending. As an alternative the microphone may be isolated by a muting switch (31) incorporated in the handset.
