Title: System for transmission of binary start-stop signals for a time division multiplex telegraph system which effects burst multiplexing of the incoming telegraph signals
IPC: H04J3/12
Filed: 1971-12-20
Abstract: 1374589 Multiplexing of telegraph channels SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 20 Dec 1971 [31 Dec 1970] 59152/71 Heading H4P A system for burst i.e. one or more character multiplexing a plurality of telegraph channels in which start-stop "S/S" bits are removed before transmission comprises, connected to each line A1 &c., a register R1 &c. which is entered in turn into a circulating register Rg1 'and a plurality of S/S identification circuits which activate an address unit i.e. a matrix M, a corresponding address from which is inserted in the register Rg1 together with a receiver which recognizes the addresses in order to direct the signals to appropriate outgoing lines with S/S bit addition. Registers R1 &c. incompletely charged are not cleared by the arrangement disclosed. The start bits are detected by network S1- S12 which is registered by bi-stable circuits Sr1-Sr12 and stop bits detected by activating bi-stable circuits St1-St12, OR gates indicating which lines carry a S/S bit with AND gates Az1-Az12 indicating which type of bit. Insertion into register Rg1 is effected by a cyclic control network R1 but in the reverse order by circulating signals stored previously in Rg1. After transferring bits of a line into Rgl, a corresponding address from matrix M is transferred in parallel to register RO when the S/S bit is present and thence into Rg1. Matrix M provides a binary signal. When gates 02, A3 are activated, binary signals from matrix M are transferred into register RO which remain until the following channel presents a S/S bit. his T is passed into section X and is thus transferred in series to register Rg1 together with bits from the preceding address. This operation is repeated for each channel until a service channel is reached on which S/S bits do not occur. Content of register Rg1 is transferred into register Rg2 and thence to line Lm. A receiver provides approximately the reverse process with identification of addresses, and switching to appropriate outgoing channels being performed by a network Li. The receiver providing reinstatement of S/S bits.

An instructional programme played back by the instructional recorder 810 is heard by the student on his headphones 812 and simultaneously recorded on his practice recorder 822 on which the student then records his response through a microphone 825 after the cessation of signals from the instructional recorder 810 has caused first detecting and control means 818, 820 to switch the inputs of the practice recorder 822 and start the operation of a memory 821. When the instructional recorder 810 reaches the beginning of the next instructional programme, second detecting and control means 819, 828 cause the instructional recorder 810 to rewind for a few seconds and then stop and also initiate the fast rewinding and playback of the recording of the student's response (or, in a modification, both the original instructional programme and the student's response) on the practice recorder 822. The memory 821 has stored the time interval between the operation of the first control means 820 and that of the second control means 828, i.e. the time allowed for the student's response, and causes resumption of the cycle of operations with the playback of the next instructional programme by the instructional recorder 810 after this time has passed once more to allow completion of the playback of the recording of the student's response by the practice recorder 822.

Title: Method and apparatus for mounting bristles on brush backs
Inventor: BERGMAN JOHN E
IPC: A46B3/06
Filed: 1978-10-26
Abstract: Plastics brush bristles (55) are joined with plastics brush backs (119) by heating the tips of brush bristle strands until they are soft and heating zones of the brush backs until they are soft. Thereafter, the soft tips of the bristles are brought into contact with the soft zones of the brush backs to fuse the bristles to the brush backs. Two relatively movable plates (33, 49) alternately clamp to and unclamp from indeterminant-length bristle strands (55) to jog the strand ends into contact with the brush backs. One of the plates carries a cutting blade (73) which cuts the strands into bristle lengths once their tips are fastened to the brush backs. For the heating step, expandable heating plates (83, 85) are moved between the brush backs and the tips and expanded to contact the tips and the brush backs and are then contracted and retracted from between the tips and the brush backs. <IMAGE>

Patent GB-2035909-A (GB)
Title: Coincidence gate ink jet
IPC: G01D15/18
Filed: 1979-11-30
Abstract: In a coincidence vector gate ink jet, a droplet is expressed from an outlet orifice 24 by a coincident pressure produced by a pair of transducers Xa, Ya at the outlet orifice. When only one of the transducers is operated, a droplet is not expressed from the outlet orifice as long as the pressure produced by that transducer remains below a given threshold. By providing pressure absorbing chambers 100, 102 this threshold pressure is substantially increased to a level substantially above the minimum coincident pressure necessary to express a droplet from the orifice. Increasing the threshold pressure increases the operating window and so permits greater latitudes in manufacturing variation and greater latitudes in pressure variation to change the size of a droplet to effect halftoning. <IMAGE>
