Title: Perforated tape reader
IPC: H04L17/08
Filed: 1957-11-12
Abstract: 822,785. Printing-telegraph transmitters. OLIVETTI & CIE S. p. A. ING. C. Nov. 12, 1957 [Nov. 30, 1956], No. 35235/57. Class 40 (3). A perforated-tape transmitter has a set of spring-actuated sensing-pins 57 which are moved perpendicularly to the tape 58 to test each row for holes and are also positively moved a short distance with the tape to avoid wear on the tape. The tape 58 is continuously advanced by a pin wheel 65 engaging the sprocket holes. The five sensing-pins 57 are each mounted on a lever 54 urged upwardly by a spring 56 and shaped to slide vertically on a shaft 55 and to engage an eccentric 53 on a shaft 52. Rotation of the eccentric 53 on the shaft 52 causes the associated pin 57 to describe an ellipse starting at A, passing through the tape hole at B moving with the tape through C to D and returning to point A. If no hole is present the pin moves from B to D along a segment. The upward movement of the lever 54 as the pin 57 passes through a hole causes a shoulder 59 to engage a lever 60 engaging a member 64 to open or close contact assembly 64<1>. The eccentrics for the five levers 54 are staggered, as shown, and the pins 57 are arranged in an oblique line so as to register when operated, with the corresponding hole positions. The sequential operation of the contact assembly 64<1> can be applied to a distributer rotating in synchronism with the shaft 52.

Abstract: 1,274,027. Drainage foils for papermaking machines. J. M. VOITH G.m.b.H. 14 July, 1969 [12 July, 1968], No. 35279/69. Heading D2A.  A drainage foil comprises a wire-supporting surface 9, following the leading edge, the surface being substantially parallel to, and in uninterrupted contact with, the wire, an adjacent drainage surface 11, having an initial surface portion diverging from the plane of the undeflected wire in the direction of wire motion, followed by at least one further surface portion, either diverging from, or adjustable to diverge from the plane of the undeflected wire in the direction of wire motion at an angle which is less than the angle that the initial portion diverges. The drainage surface may be shaped as a catenary. There may be a joint in the surface, this joint preferably being situated 20-50% of the way along the foil in the direction of wire motion. There may also be a pivot between the wire-supporting surface and the drainage surface (Fig. 6, not shown). In the drawing, initial portion 3' and trailing portion 3" are joined by flexible portion 7. The disposition of the two surfaces may be changed by means of studs 13 and surfaces 14. Surfaces 14 are attached at intervals across the machine, and taper in the crossmachine direction. Each surface has a stud 13 bearing on it, the studs being carried by a rod 12 whose position across the machine may be varied by conventional screw means (Fig. 2, not shown). Springs may be incorporated between base 2 and portion 3" to hold this portion in contact with studs 13. Other means of adjusting the disposition of the trailing surface, e.g. a turnbuckle (Fig. 6, not shown) may be used. The entire foil construction may be tilted. An insert 10, or the entire leading edge, may be formed of a wear-resistant material e.g. a ceramic or tungsten carbide.

Title: Character generator apparatus
IPC: G09G1/12
Filed: 1970-07-22
Abstract: 1325594 Cathode-ray tube circuits TEKTRONIX Inc 22 July 1970 [28 July 1969] 5472/70 Heading H4T [Also in Division G4] Data, for tracing alphanumeric characters on a C.R.T. display is stored as a set of pairs of X, Y values representing successive points (or nodes) to be traced, the pairs of values being provided each by a triplet of transistors with common emitter and base connections, the emitter areas A x , A y , A z  of a triplet defining X and Y as A x /A x  + A y  + A z  and A y /A x  + A y  + A z , respectively. The bases of the triplets are energized in turn to successively partition the current from a constant-current source between the collectors of the triplets, two collectors of each triplet providing X and Y signals for the corresponding spot point. The energization pulses for successive bases partially overlap to ensure a more-or-less continuous spot movement. Fig. 6 illustrates the realization of the arrangement as an integrated circuit with ten character stores of which one (that generating the digit 9) is shown as a set of eight triples 101-108, the remaining nine similar stores being indicated schematically at 160-168. A sawtooth waveform from 118 is applied in direct and inverted form to points 96 and 94 at the ends of a ladder resistance network with resistance values selected so that the voltages at the bases of the transistor triplets vary to cause each in turn to conduct during a single sawtooth. The character for display is selectively connected at 110, 170 &c. to a constant current source, and the outputs taken from 114, 112. The outputs from each triplet are determined by the number of unit transmitter areas of the X, Y and Z transistors to which connections are actually made, in accordance with the formulae above. In a modification (Fig. 11, not shown) the ladder resistance network is replaced by a ladder of back-to-back diode pairs; the ladder networks are the subject of Specification 1,325,595. The Specification describes and illustrates the integrated circuit construction and fabrication.

Convention date, Nov. 30. [Class 140.] In a process for impregnating electrical materials such as cables, the impregnating mass is subjected to a multi-stage preliminary treatment with increasing pressure reduction. Oil from the tank 3 is forced by pump 11 to a mixer 4 heated by pipes 58, 59. Oxygen is then displaced from the mixer by nitrogen admitted from a tank 5. Resin is introduced through the lid 9 and solution effected by heating and stirring. The pressure is 1 atmosphere, or somewhat more after heating. The product passes through filter 12 to tank 13, provided with stirrer 14 and connected through trap 16 and pipe 20 to a vacuum pump 30 giving a vacuum of 40-50 mm. Removal of gas and water occurs, the tank being heated by pipes 60, 61 to a temperature below 100‹ C. The contents are forced under pressure by pump 21 to a filter 17 and then pass to a tank 24 also connected to the pump 30 and having a stirrer 25. Under the action of pumps 40, 41 the mass passes to tank 35 under a vacuum of, for example, 1 mm. produced by pump 39. The temperature is above 100‹ C., and devices such as conical surfaces are provided over which the mass flows in a thin layer. The withdrawing pump has a greater power than the supplying pump to prevent accumulation,. and the mass passes immediately to either of the impregnating vessels 45, 46 which contains the cable and is exhausted by the high vacuum pump 66. Heating is effected by a pipe 62. The pipe to pump 66 is then closed and impregnation continued while the mass is subjected to pressure by pumps 40 or 41. The mass is then cooled and the vessel opened. Oil vapour condensers 36, 49, 50 are provided, connected with cooling pipes 64, 65, and the heating pipe 62 to facilitate their emptying. The highvacuum pumps 39, 66 exhaust into the preliminary pump 30, a condenser 32 being interposed in which most of the water condenses, the remainder passing to pump 30. Excess impregnating mass is returned by pipe 48 to the vessel 13 together with the drainings from the treated cables which are placed on platforms 54, 56.

Abstract: 1468115 Recovering cellulose E I DU PONT DE NEMOURS & CO 4 Sept 1975 [5 Sept 1974] 36480/75 Heading C3A Cellulose is recovered from coated, plasticized regenerated cellulose by a process including the following steps: (1) The starting material is comminuted. (2) The plasticizer is removed to leave porous, coated cellulose. (3) The coating is removed by means of a solvent. (4) The solvent is driven off by exposing the cellulose at an elevated temperature to stream of an inert gas containing water vapour. The conditions in this step must be such that the regenerated cellulose is left with a water content of 7 to 22% by weight. The action of the humid gas may be assisted by a pre-drying step to remove much of the solvent. Whether or not this is done, the cellulose exposed to the gas must contain at least 6% by weight of the solvent, based on the dry cellulose weight, when exposed to the gas. Optionally a portion of the final water content can be added as liquid water to the cellulose before or during treatment with the humid gas. In examples the coating is polyvinylidene chloride and the plasticizer propylene glycol. The latter is removed by treatment with water and ethanol, and tetrahydrofuran is used as the solvent for the former. The predrying is done by passing warm, dry nitrogen through the cellulose and the final, humid drying gas is either nitrogen or steam.
