Title: Improvements in or relating to the method of spot-carbonizing paper by typographic printing and apparatus for same
Inventor: WAROFF LOUIS
IPC: B41L1/00
Filed: 1954-03-08
Abstract: 754,547. Printing. GAVRIN PRESS, Inc., A. J. March 8, 1954, No. 6670/54. Class 100 (2). Inking -apparatus ; printing surfaces.-Paper is spot-carbonized typographically by continuously transferring a normally solid carbon ink, melted to substantially its optimum printing temperature, to a heat-insulating resilient transfer roller which passes it directly to a heatinsulating resilient typographic plate for printing. With this arrangement, with the optional addition of a heated base for mounting the printing plate, internal heating of a conventional ink-distributing train or the provision of other heating means, e.g. for pre-heating the paper, is unnecessary. As shown a thermostatically controlled heating element 12 maintains ink 11 at the appropriate temperature (usually in the-range 200-250‹ F.); a rubber or other resilient heat-insulating roller 14 transfers the ink from a metal fountain roller 13 to a plate cylinder 15 maintained at fountain temperature by a thermostatically controlled heating element 16; the plate consists of a thin copper sheet to which is vulcanized a rubber typographic printing surface. The paper web 21 after printing passes over a cooling roller 23 and is punched with register holes by rotary perforator 24, 25.

Abstract: 1,058,592. Electric analogue calculating. WHITWORTH GLOSTER AIRCRAFT Ltd. Feb. 19, 1964 [Feb. 19. 1963], No. 6677/63. Heading G4G. In a transfer function analyser for electrical systems, the electrical signal output f(t) obtained from the system to be analysed, when a particular A.C. reference signal a sin #t is applied to its input, is summed in unit 11, Fig. 1, with two feedback signals; one feedback signal is derived by multiplying the output x of the summing means by a function of time, and the other is derived by multiplying the final output p of the analyser by a sin #t or a cos #t ; the output of the summing means is also multiplied by a sin #t or a cos #t and then integrated to derive the final output. The equation to be solved is where and a 0  is the nominal value of a. The unit 11 may be a high gain amplifier which sums to zero its three inputs 0 x  + f(t) - pa in #t. so that The output x of the amplifier is multiplied by a sin #t in unit 12 and integrated with sign reversal in unit 13 to give the final output p which is fed to a display 17, an output terminal 18, and through a sign reversal unit 15 to multiplier 16 which produces the input - pa sin #t for the amplifier 11. The input #x for the amplifier is derived by the feedback of x through a motor driven potentiometer 14 which supplies a linear function of time. A second circuit using the same amplifier 11 and potentiometer 14 but with the other units duplicated, may be provided to calculate the quadrature component. Fig. 2 (not shown).

Title: Digital control for the conveyor in a cooling bed for rolled stock
Inventor: PFISTER MARCEL CHARLES
IPC: H02P7/00
Filed: 1969-02-10
Abstract: 1,263,335. Rolling. M. C. PFISTER. 10 Feb., 1969 [26 March, 1968], No. 6999/69. Heading B3M. [Also in Division G4] In a digital control system for cooling rolled stock, successive packages of the rolled stock are deposited on the cooling bed separated from each other by amounts predetermined by the number stored in a pre-aelector VW3 (Fig. 3). In the embodiment described the useful length L of the cooling bed is stored in a preselector WV1. When a first package is loaded on to the conveyer a detector D11 delivers a "1" signal to enable pulses to be fed into counters Z1, Z2. When the package passes the detector the count in both counters continues and pulses are additionally counted in counter Z3 until this count is equal to the preselected spacing in selector VW3 when the counter Z3 is reset and the count in counter Z2 is terminated. When the conveyer has moved an amount corresponding to the length of the cooling bed the count in counter Z1 is terminated and the conveyer returns, leaving the package of rolled stock on the cooling bed. The count in counter Z2 is then transferred to counter Z 1 and the conveyer transports the next package to the cooling bed, the conveyer being stopped at an earlier time since counter Z1 starts counting from a number representing the width of the first stock package plus the desired spacing. This process is repeated until the count in counter Z2 corresponds to the preset value VW1 when the cooling bed is full and a gating device directs further stock to a second cooling bed.

Title: Improvements in apparatus for stopping trains independently of drivers
IPC: B61L3/04
Filed: 1921-03-04
Abstract: 181,433. Ratcliffe, W. H. March 4, 1921. Track apparatus for stopping trains.-Apparatus for stopping a train independently of the driver has depending arms at each side of the engine joined by levers; each arm has a plunger working therein and is connected bv a train of levers to valves to cut off steam and to apply the brakes when the arms engage a pivoted inclined plane upon the track. The arm A is pivoted to a bracket B on the side of the engine frame, and the plunger D passes right through the arm, then through the bell-crank lever E. It is then bent and fixed to a guide-block F sliding in a slot in the lever H, which is pivoted on a bracket and secured to a bell-crank lever J which operates the.engine reversing lever M through the rod L. An arm A<1> and plunger D<1> are arranged on the other side of the locomotive for use when the engine is running tender first and the two sets are connected together by bell-crank levers and the link O. A bell-crank lever U is connected between the link O and the rod V, which passes into a bracket W and enters a groove c in a rod Z, Fig. 6, thereby holding the rod in place and holding open the valve x in the main steam supply. A rod j is attached to the bell-crank lever E and to the lever n for operating the brake-regulator s through an adjustable rod t. Wedge-shaped pieces AA are pivoted along the track and are operated from the signals. When the line is clear the pieces AA occupy the position shown in dotted lines in Fig. 8, but when the signal is in the danger position the pieces are raised to form inclined planes engaged by the end of the plunger D on the. engine. The arm A is tilted about its pivot, and operates the bell-crank levers E, U, the latter of which pulls the rod V away from the rod Z, thereby allowing the spring v to close the steam valve x, while the former, E, operates the brake valve. The plunger D is raised by the reversing gear when in the reverse position, to clear the wedge pieces on that side of the track. The Provisional Specification states that the closing of the throttle valve causes a lever to engage a rack so that the driver must descend to disengage the lever before he can operate the throttle.

Abstract: 703,041. Separating solid materials. BERRY, F. J. B. March 21, 1952 [April 28, 1951], No. 7427/52. Class 117 In apparatus for separation of rough coal into pure coal, shale and impurities of intermediate density comprising sloping upper and lower perforated tables 20, 21, up through which a gaseous current is passed to stratify the mixture, and which are oscillated in a vertical plane with an elliptical motion to feed the denser material in contact with the tables up the slopes, each table has outlets at each end, the upper table receives the products to be separated and one outlet 27 of the upper table is above and supplies an intermediate zone of the lower table. The lighter coal discharges over a lower outlet 23 of the upper table 20 and the heavier shale and impurities to the lower table through a constricted outlet 27. On the lower table the denser shale then passes forward to an outlet 31 and intermediate density impurities over an inner and lower outlet 32 to a passageway 33 leading to a discharge outlet by lateral passages 30. Thus all outlets discharge the graded products longitudinally of the tables. The outlets 23, 27, 31 aand 32 may be adjustable in height. Both tables are connected underneath by flexible bellows to a fan by independently regulated air passages A, B. The tables are oscillated with an elliptical motion with axis in the direction of inclined guides 18 supporting rollers 17 on the table frame by eccentrics 12, 13 pivoted to the table frame at points whose line of join is parallel to the guides 18. A plurality of side by side separators may be used feeding transverse common collectors. In a modification for use when the denser products are predominant the upper table 20 slopes upwardly away from the lower table and the positions of the eccentrics and roller guide 18 are reversed. In this case the lateral passages 30 discharging intermediate density products may be disposed beneath the upper table 20.

Abstract: 730,917. Filters. BLACK-CLAWSON CO. March 20, 1953 [March 20, 1952], No. 7750/53. Class 46. A rotary suction drum filter of the type including a cylindrical casing 21, a cylindrical strainer 22 spaced from its outer surface, a circumferential row of longitudinally-extending cells 11, an outlet 11a in the casing leading from each cell 11, and rearwardly-bent discharge ducts 12 connecting the outlets with the interior of the drum has means such as pipe 13, connecting each cell with the rear portion of its discharge duct, for admitting air into the cells during their upward movement so that no "trap" is formed in the discharge ducts 12 before a sufficient quantity of liquid is present in them for maintaining vacuum in the cells until the outlet ends of the ducts 12 have moved below the inner liquid level. A cell 11b is shown near its lowermost position in Fig. 1, in which position, as a result of the dimensions chosen for the cell, it is not completely filled, and the outlet 11a is not covered with liquid. After moving to the position of Fig. 2 (not shown), the outlet 11a is completely closed by liquid, but air entering the cell through the pipe 13b permits more liquid to flow from the cell into the discharge duct 12b, this state of affairs continuing until the pipe 13b has reached the position of Fig. 3 in which the liquid in duct 12b closes the pipe opening. Liquid continues to pass through the strainer 22 into the cell 11b and thence into the duct 12b where it is supported by the continuously-increasing vacuum in the cell due to the expansion of the air trapped within the cell. Instead of a pipe 13 each discharge duct 12 may be provided with a hollow bead 14, Fig. 5, preferably set at such an angle (as shown) as to guide the discharging liquid to the filtrate outlet and thus keep the interior liquid level low. The interior liquid level may be kept substantially constant (so as to control the capacity of the apparatus) by providing for varying the drum speed such as by a variable speed drive 25 governed by the interior liquid level.
