Title: Party-Line Digital Data Transmission
Inventor: ROBINSON EDGAR ROSINO
IPC: H04L12/403
Filed: 1968-06-28
Abstract: 1,172,057. Digital transmission systems. WESTERN ELECTRIC CO. Inc. 28 June, 1968 [29 June, 1967], No. 30953/68. Heading H4P. [Also in Division G4] The control station of a digital transmission system comprises a control station and a number of out-stations all connected to the same line polls, each of the out-stations in turn. An out-station having a message to transmit indicates to the control station to which of the out-stations the message is to be sent, the control station readying the required receivers and then causing the calling out-station to transmit its message. The control station first sends a poll initiation signal which readies all the out-stations. This signal is followed by the poll signal of the next out-station due to be polled. Under the control of an operator that out-station replies with a signal indicating whether or not it wishes to transmit a message. If there is no message the next out-station is polled, but if a message is ready the control station sends a signal, unique to the polled out-station, that causes that station to transmit a list of the addresses of out-stations which are to receive the message. The waystations not polled are set to quiescent. The control station stores the list of addresses and when the list has ended it sends a signal readying all the out-stations. The first stored address is now transmitted by the control station, the called out-station returning an acknowledgement signal and readying its printer, whereupon the control station cancels that address from the list and calls the next listed address. When all the required outstations have been called, the control station sends a signal which enables all the called outstations and starts the message transmitter at the polled out-station. When the end of message signal is sent the out-stations revert to quiescent and the control station sends a second poll initiation signal to repeat the cycle.

Title: Improvements in wire tensioning, twisting and package binding machines
IPC: B65B13/28
Filed: 1923-12-17
Abstract: 221,771. Cary Manufacturing Co., (Assignees of Weeks, C. S.). Sept. 13, 1923, [Convention date]. Wire strainers having separate levers for tensioning and for securing wires around bales &c. The levers are arranged so that either holds the apparatus in place during actuation of the other, and means are provided for holding the wire under tension before the operations of securing the wire and cutting-off the spare ends are performed, such means being separate from those used to place the tension on the wire. The tensioning means comprise a shaft B, rotated by a lever L and carrying at its opposite ends lugs J, K to which are secured anchoring devices M, N respectively, for the ends of the binding wire. The device M, Figs. 6 and 9, includes a spring- pressed pivoted pawl m biting into the wire, which may be pre-deformed near one end as shown, and the other device N, Fig. 5, comprises a pin n around which the wire is wound. The wire is passed from the clamp M, Fig. 9, across a plate F having a curved guide edge, or a guide roller F<2>. through shearing plates D, E and the slotted pinion C, around the bale, again through the plates D, E and pinion and across a second curved guide plate H and secured to the other clamp N. Intermediate between the clamp M and plate D and between the plate E and clamp N are fixed the means for retaining the tension on the wire, comprising a horizontally rotatable spring-pressed pivoted pawl G, Fig. 1, having a serrated edge, and a vertically rotatable spring- pressed pawl 1, Fig. 5, respectively. The wire is passed between these pawls and the plates coacting therewith and the tensioning lever L is swung upwardly and forwardly from the position shown in Fig. 1 until sufficient tenion is put on the wire, whereupon the lever is swung back to its original position, the pawls G, I meanwhile maintaining the tension on the wire. The operator thereupon presses down the lever L with one hand to give a good bearing whilst rotating the other lever P with the other hand. This lever is secured to a gear segment 0 to actuate the slotted pinion C to twist the wires together, and carries a cross-bar r which actuates spring- pressed pivoted cutter blades Q, R to sever the spare ends of the wire. After the lever P is restored to the position shown in Fig. 1, pressure thereon similarly affords a good bearing during the rotation of the tensioning lever.

Filed: 1958-10-03
Abstract: 857,274. Moulding reinforced synthetic resins. MONTECATINI SOC. GENERALE PER L'INDUSTRIA MINERARIA E CHIMICA. Oct. 3, 1958 [Oct. 4, 1957 ; Jan. 3, 1958 ; June 9, 1958 ; Sept. 22, 1958], No. 31654/58. Class 87(2). [Also in Group VIII] A layer 13, Fig. 1, of glass or other fibre is passed over a support 5, impregnated with a polyester or other curable synthetic resin 15, covered with a layer 8 of impervious non- adhesive material, e.g. cellulose acetate, and pressed between rollers 6, 7, the roller 7 having a substantial covering of cellular rubber or synthetic resin, or other deformable elastic material. A further sheet 2 of cellulose acetate may be fed between the fibrous mat 13 and the support 5, so that both sides of the mat are covered during the rolling. The fibre mat is heated by infra red lamps 18 before it receives the resin from a tank 16. After rolling the laminate may pass to a corrugating apparatus as described in Specifications 748,368 and 824,755, where the cellulose acetate sheets are removed. Separate lengths of resin-reinforced fibrous material may be made in apparatus comprising a series of metal platens travelling on rollers 41, Fig. 3, and receiving a sheet of cellulose acetate from a reel 412 and fibrous material from a reel or reels 413 and cut by shears 415.

Title: Metering valve for hydraulic brake systems
IPC: F16D65/28
Filed: 1965-07-26
Abstract: 1,042,545. Hydraulic brake systems. KELSEY-HAYES CORPORATION. July 26, 1965 [Aug. 6, 1964], No. 31851/65. Heading F2F. A metering valve, for insertion in an hydraulic line between a master cylinder and front wheel brakes of a vehicle, particularly where the latter are disc brakes and the rear wheel brakes are of duo-servo type and are fed via a pressureproportioning valve 15 (Fig. 1, not shown), is adapted initially to block flow of fluid to the disc brakes and, after master cylinder pressure has risen above a predetermined value, to provide a pressure drop which gradually reduces in value until at a further, higher, predetermined master cylinder pressure it becomes zero and full master cylinder pressure is applied to the front wheel brakes. The valve comprises a sealing member 25 carried by a piston 24 which is acted on by a spring 27 to resist flow of fluid between inlet 22 and outlet passage 30. Associated with the piston is a plunger 34 exposed to atmospheric pressure at its end remote from the piston, a flange 34a of the plunger abutting the piston throughout operation of the brake, so that, when pressure at inlet 22 acting on the piston 24 has risen above a value sufficient to overcome spring 27, the reduced pressure transmitted by the valve acts on the plunger and gradually modifies the pressure drop across the valve as inlet pressure rises further, until a pressure is reached at which the pressure acting on the plunger alone is sufficient to overcome the spring 27 so that the valve opens fully, input and output pressures thus being equalized. By-pass passages 33, 38 in the piston are closed by a flap valve 37 throughout brake operation, the flap allowing fluid to pass through the passages 33, 38 on brake release. The plunger 34 is adapted to be engaged manually so that should it be desired to bleed the brakes the flap valve can be moved clear of the passage 38 and a block 39 having passages 40, 41 moved into register with inlet passage 23 to facilitate the bleeding operation. In a modification (Fig. 4, not shown) the flap valve is replaced by a ball valve 59 sealing off the interior 73 of the piston from the inlet when the brakes are applied, there being lost-motion between the piston and a head 70 of a threaded coupling bolt 69 carried by the plunger, and a second spring 66 acting independently on the plunger. The spring 60 acting on the piston is adapted to be overcome by inlet pressure acting on the piston before outlet pressure acting on the plunger overcomes the spring 66, so that the initial pressure drop across the valve is maintained constant until an intermediate pressure is reached, beyond which it reduces as in the previous embodiment until the pressure acting on the plunger is sufficient to overcome both springs and open the valve fully to equalize input and output pressures.

Filed: 1974-07-18
Abstract: 1477517 Logic circuit array GENERAL ELECTRIC CO 10 July 1974 [18 July 1973] 31859/74 Heading G4H In a logic circuit array of Boolean logic cells 11 &c. arranged along crossing sets of parallel lines ("rows" R, "columns" C) including a plurality of row conductors 30 &c. (one or more of which are associated with each row R) and a plurality of column conductors 12, &c. (one or more of which are associated with each column C), at least one row conductor is segmented to form two or more electrically isolated but physically collinear segments (e.g. 24-1, 24- 1<SP>1</SP>), each such segment having associated with it a group of at least two logic cells, and for each such segmentedconductor, a pair of column conductors which cross it to the left and right of the segmentation area 27 also cross at least one further row conductor 21 which is associated with another row R and which is unsegmented between the respective pair of crossing column conductors (e.g. 24 of row N), each such further row conductor having associated with it a group of at least two logic cells, each segmentassociated group being connected by two separate column conductors respectively to a further conductor group. In the embodiment of Fig. 1, diodes D11, D11<SP>1</SP> &c. are arranged in an array R1-RN, C1-C5 of logic cells. Fusible links are provided between the diodes and column lines 12, &c. and in row lines 24 &c. (link 27 divides rowline 24 into segments 24-1, 24-1<SP>1</SP>); the links may be fused during initial masking operations or subsequently by a laser micromachining process, or by electrical "programming" using row and column addressing circuitry 40, 44, 48, 50 Fig. 2, (not shown illustrates circuitry for segmenting the row conductor 24). As shown, row 24 is segmented while row N is not (although there is a fused link at 27<SP>1</SP>), while diodes D11<SP>1</SP>, D12, D14<SP>1</SP> &c. have been separated from their column conductors. This arrangement produces the functions f 1  = AB and f 2  = f 1 C + C. The embodiment of Fig. 3 is similar, but the logic cells, e.g. E11, contain FETs T1-T4 &c., where the gates of T1, T3 are floating. Here T1, T2 are "active" (T1 activated by injection of charge during programming) and T3, T4 are "inactive". A switch S2 selects the programming PO and circuit operation CO modes. Transistors T7, T8 are used to achieve segmentation 24-1, 24-1<SP>1</SP> of the row line. In the embodiment of Fig. 4, row line segmentation is effected by circuits 32<SP>1</SP>, &c. containing enhancement mode MOSFETs which receive and store information in the form of avalanche injected charges on their floating gates (with charge accumulation they conduct). Before programming, there is no charge stored on the electrodes of TS3, TS4 so that TS3 presents an open-circuit and conductors 24-1, 24-1<SP>1</SP> are segmented. If segmentation is not required, charge is stored by means of switches Sl, S2 which are moved to their PO positions. The array may be used in the same way as an "associative" or content-addressed memory.
