Title: Method and means for the preparation of sample cards carrying knotted sample threads
IPC: B65H69/04
Filed: 1949-11-22
Abstract: 678,942. Sample card packages. ERB, E. Nov. 22, 1949 [Nov. 30, 1948], No. 29845/49. Class 94(i). A method for knotting threads on perforated strips in order to produce sample cards, comprises the steps of holding the threads across the surface of a perforated strip, operating two independent hookprovided combs to engage and draw the threads through the perforations so as to form loops, bringing the respective ends of the thread loops together, passing one of the combs through the loops clear of the strip to seize the loop ends, withdrawing said comb to pull ends around the adjacent edge of the strip and through the loops to form the knots, and separating the combs from the knotted threads. Each comb includes a body 1 to which is secured a row of hooked members 2 each associated with a slidable fork-ended clamping member 9. The members 9 are moved, to grip a thread in association with the hooks 'or to release a thread, by a common operating bar member 4 acting through springs 7 associated with each member 9 and actuated by levers 10. In operation, a comb 1a carries threads 21 threaded through perforations in a transverse guide rail 23, from the transverse guide rail 23 across a perforated sample card 13 held in position by a transverse plate 14. Two combs 1b, 1c are then moved up through the perforations in the card to engage the threads stretched thereover and down to pull the threads in loops through said perforations, the threads having been clamped at the guide rail 23 by combs 1d, 1e. The threads are then cut between the combs 1d, 1e and the comb 1d moved over adjacent the comb 1a. The comb 1c is released from the loops and moved therethrough to hold the ends of the threads, Fig. 6. The combs 1a, 1d then release the ends of the threads which are carried by the comb 1c back over the edge of the card and through the loops to form a series of knots, the comb 1b being released. For the knotting of the threads on the next sample card the comb 1e carries the threads across the card. Specification 637,427, [Group VII], is referred to.

Title: Improvements in regulating means for elastic-fluid prime movers
IPC: F01D17/26
Filed: 1926-11-27
Abstract: 262,133. British Thomson-Houston Co., Ltd., (Assignees of Standerwick, R. G.). Nov. 28, 1925, [Convention date]. Transmitting - mechanism. - Regulating means for turbines &c. comprises a pump 21 driven by the turbine through gearing 17, 18 and pumping fluid through a pipe 24 and valve 26 to a pipe 28 opening into a cylinder 14 below a spring- pressed piston 13. The piston 13 is connected by a rod 12 to operating mechanism 10, 11 for controlling the steam supply valve 6 of the turbine. The pipe 24 has a relief valve 25 so that pressure therein is constant, and the pipe 28 has a by-pass 29 opening into a casing 31 containing a slidable ported bush 32 of a valve 36. The valve 36 is controlled by a centrifugal governor 37, so that, if the speed varies, the valve is moved to vary the escape of fluid from the pipe 29 and consequently the pressure in the pipe 28 and cylinder 14. The piston 13 then adjusts the valve 6 to vary the stream supply. The movement of the piston 13 adjusts the valve bush 32 relatively to the valve 36 by means, of linkwork 39. 38, 34 to restore them to their former relative position. The movement of the lever 39 operates a valve 49 of a connecting device C controlling a port 45 between a cylinder 43 and a cylinder 41 containing a spring-pressed piston 42. Fluid escapes from under the piston to a pipe 47 and the piston descends, pulling down the lever 39 and lowering the valve bushing 32 until the valve 49 again closes the port 45. The movement of the bushing 32 increases the pressure in the pipe 28 and opens the valve 6 a little more. The form shown in Fig. 3 is adapted for maintaining a constant fluid pressure, say, in the turbine exhaust. The lever 39 is pivoted at 52 to a lever 53 pivoted to the rods of the valve 49 and piston 42. The valve is pressed down by a spring 57 and its rod is connected to a diaphragm 59 exposed on its underside to the pressure to be controlled. Variation of the pressure moves the diaphragm and valve, allowing the piston 42 to descend and operate the levers 53, 39, 34, thereby adjusting the valve 6 to vary the steam supply to the turbine.

Title: Improvements relating to teleprinter receivers
IPC: H04L17/18
Filed: 1953-10-30
Abstract: 732,094. Printing - telegraph receivers. AUTELCA AKT.-GES. Oct. 30, 1953 [Nov. 1, 1952], No. 30099/53. Class 40 (3). In a teleprinter-receiving device in which the received elements of a signal are translated and applied to selecting discs by translating mechanisms comprising control levers, swords and T's for each element actuated from a control cam-shaft, the individual translating mechanisms are grouped in circular formation around the cam-shaft so that the control members are successively operated and cause the individual swords to co-operate with an appropriately shaped radial portion of a member which is selectively positioned according to the nature of the received elements of the signal. The receiving magnet 22 has an armature 22c which, in response to the start element, moves a rod 24 to operate a clutch to connect the cam-shaft 5 to the motor 1. The actuation of the armature in response to the signal element longitudinally moves a rod 25 carrying a boss 26 so that, in response to the elements of the two kinds, arcuate sensing levers 27, 28 respectively move inwardly under control of a cam 30 and lock the armature in its selected position. By means of a pin 28b the inward movement of the lever 28 rocks a frame 32 with five arms, each having a central recess 32b, Fig. 5, and side arms 32a with projections 32c, 32d co-operating with turned-up projections 10c, 10d on pivoted sword members 10 mounted on a shaft 17 carried by a corresponding control member 9 mounted on a stub shaft 13 carried on a fixed plate 4 and biased by a spring 14 to its clockwise position. After the reception of a signal element, a cam 6a rocks a member 9 to lift the associated sword 10 so that its projecting finger 10c or 10d engages the projection 32c or 32d of the associated radial arm of the member 32. When a sword 10 is is moved inwardly by the return movement of the member 9, its pointed end 10a engages one of the sloping sides of a knife edge to move, if necessary, a rocking lever 20 secured to a shaft 18 carrying a change-over lever 12 which rocks the associated selecting disc 11. The remaining discs 11 are similarly displaced, if necessary, and the printing or control function is initiated by selecting levers 34 which, under the action of individual springs 36, drop into aligned slots in the discs 11.

Filed: 1958-09-23
Abstract: 850,766. Electrical digital data-storage apparatus. SPERRY RAND CORPORATION. Sept. 23, 1958 (Oct. 18, 1957], No. 30432/58. Class 106 (1). A flexible disc-shaped magnetic record member 32 is pneumatically positioned by supplying air at equal pressure to two chambers 16, 18, lying one on each side of the record member and comprising at least in part a porous material pervious to air, the porous material 22, 24 being located adjacent the corresponding side of the record member. Thus movement of the disc about an axis perpendicular to its axis of rotation creates an unbalance of air pressures on the two sides of the disc and generates a restoring couple. As shown the chambers 16, 18 are annular and porous discs 22, 24 of a sintered powdered bronze alloy form the wall of the chambers adjacent the record disc. The porous discs are bolted together and to remove the record member it is necessary to undo the bolts. In a second embodiment the upper disc 22 is replaced by two curved strips (Fig. 4, not shown) with the interfaces separated so that to remove the record member it is sufficient merelv to bend the record member to pass through the slot thus formed. Transducing heads 30 may be mounted in the porous material and preferably the porous members 22, 24 are spaced apart a distance equal to twice the distance record member to transducer head plus the thickness of the record member. Not all tho record member need be under the influence of pressurized air at any time, it is sufficient that only the part of the surface being utilized at that time should lie between the chambers 16, 18.

Title: Arrangement for synchronizing pulse generators
IPC: H04N5/12
Filed: 1959-09-07
Abstract: 881,793. Automatic phase control systems. FERNSEH G.m.b.H. Sept. 7, 1959 [Sept. 6, 1958], No. 30443/59. Class 40(5). A pulse train Vf frequency obtained by frequency division from a master oscillator 10 is phase locked with synchronising pulses V<SP>1</SP> by applying both to a bi-stable trigger circuit 3 whose output cyclically varies the frequency division ratio between two integral values, a desired and an undesired ratio, until phase synchronism is reached, the duration of the undesired division ratio progressively decreasing and being proportional to the difference in time between corresponding edges of the two pulse trains. To this end are 18 of the quinary dividers 18-21 may have its division ratio increased to 6 by bi-stable circuit 3 with D.C. output voltage alternated between two valves by the pulses V, V<SP>1</SP>, respectively, the pulse train V causing a drop in collector operating potential of one of the transistors of a transistor multivibrator 18 to which pulses from oscillator 10 are applied so that relaxation delay in one unstable condition is increased and the division factor increased to a higher integral value. Alternatively the division factors of all four dividers 18-21 may be progressively altered. The pulses V, V<SP>1</SP> may be television vertical synchronizing pulses, and the oscillator 10 may be synchronized with incoming horizontal pulses H by applying output pulses A through a binary divider 11, to a sawtooth generator 12 whose output is phase compared with H at 13 to derive a control voltage R locking and stabilizing it, local horizontal synchronizing pulses H being derived from divider 11. V, V<SP>1</SP> are therefore finally synchronized to within half a line of output H.
