Filed: 1935-12-23
Abstract: 467,834. Printing-machines. CAMMEN, L. Dec. 23, 1935, No. 35605. [Class 100 (ii)] Inking-apparatus.-To prevent excessive evaporation of the ink in a rotary intaglio printing-machine, the printing cylinder is provided with a casing which on one side is rendered airtight by the doctor blade and its supporting structure, and on the other side is set at about one sixteenth of an inch from the cylinder to form a passage opening to the atmosphere, the cylinder rotating in a direction from the open end of the passage towards the interior of the casing and causing a state of turbulence in the passage to prevent substantial exit therefrom of the volatile ink components. The ink is supplied to the printing-cylinder 11 from a tank 14, surplus ink falling over a baffle 35 into the bottom of the casing 34 and being returned to the tank 14 by a pump 13 and pipe 17. The doctor 37 is carried by a block 40 in airtight contact with a flange 38 on the tank 14. The casing has a portion extending from the points 36 to 47 set at about one-sixteenth of an inch from the cylinder and of a length at least twenty-five times its distance from the cylinder. The air carried by the cylinder into the narrow passage thus formed causes a state of turbulence which opposes the passage therethrough of ink vapour. When the machine is at rest the opening at 47 may be closed by a rubber flap.

Title: Improvements relating to vehicle steering apparatus
Inventor: TARLTON FRANK HENRY
IPC: B62D5/24
Filed: 1953-12-23
Abstract: 777,866. Vehicle power steering. ROLLS-ROYCE, Ltd. Dec. 8, 1954 [Dec. 23, 1953], No. 35697/53. Class 79(5). In a vehicle power steering mechanism a gear mechanism interposed between the hand wheel 16a and a steering gear worm 11 includes a part moved by torque reaction, which movement is transmitted through operating means arranged within an internal bore in the worm to actuate a valve 28 to initiate power assistance. As shown in Fig. 1, the invention is applied to a vehicle steering arrangement comprising a three-part track rod 7, the middle part being connected to bell crank levers 8, 9. The lever 8 is connected by a link 15a to the drop arm 15 of the steering gear 10 controlled by the hand wheel 16a, and the lever 9 is connected by a link 24 to a hydraulic motor 25. Conduits 25b, 25c connected the motor 25 to the valve 28 which is further connected by conduits 44, 49 to a sump 27 and a pump 26. A ported valve member 28a, Fig. 4, resiliently loaded into a medial position within the valve 28 has a slotted connection with an end 37 of a member 35, the end being maintained in the slot by a screw 38. The member 35 has a socketted connection at 34 with the worm 11 and another socketed connection at 32 with the steering shaft 16, the member 35 being pinned at 36 to a part-spherical element of the connection at 32. The shaft 16 and worm 11 are axially displaced by an amount X, and the shaft 16 and worm 11 are interconnected by an internally toothed member 30 and an externally toothed member. Rotation of the wheel 16a causes movement of the member 35 which is transmitted to the valve member 28a to initiate hydraulic powerassisted steering and also causes movement of the worm 11 which is transmitted through a cam element 13 of the gear 10 to move the drop arm 15. In another embodiment, Fig. 5, the shaft 16 and worm 11 carry sun gears 17, 18 of a bevel differential gear, the planet gears 22 of which are mounted on a carrier 19 secured to a shaft 20 extending through the worm 11 and carrying an arm 23 having a slotted connection with the valve member 28a whereby the hydraulic steering is initiated by rotation of the planet carrier 19, subsequential rotation of the shaft 16 after the member 28a has reached its limiting position causing rotation of the worm 11. The member 35 and shaft 19 may be linked to the valve member 28a. The valve 28 may be mounted on the steering gear 10 either directly or through noise-reflecting connections. Specification 705,372 [Group XXIX] is referred to.

Title: Improvements in slag tap furnaces
IPC: F23J1/00
Filed: 1963-09-10
Abstract: 1,061,587. Baffles. L. & C. STEINMULLER G.m.b.H. Sept. 10, 1963 [Sept. 24, 1962], No. 35698/63. Heading F4B. In a slag tap furnace having a combustion chamber with a horizontal part separated from a radiation chamber by a slag screen, baffles in the horizontal part of the combustion chamber deflect the gases flowing to the radiation chamber to improve the slag separation. Combustion gases from staggered burners 11, 12 are deflected by baffles 6, 7, 8 so that they are spread over the width of the slag screen 4. Each baffle is formed of a band of water tubes 16 which run parallel to the furnace floor, and is formed in sections, each supported by flow and return pipes 26 arranged to provide little resistance to gas flow. The baffles are staggered, with the lowest baffle downstream. The bottom tube of each baffle may be set forward to form a slag trough. The tubes of each baffle may be at an angle to the furnace floor, with the lowest point in the middle of the furnaces. The tubes of the baffles may be studded to support a refractory coating.

Title: Improvements in or relating to tape feeding apparatus
IPC: G11B27/13
Filed: 1962-09-19
Abstract: 981,102. Tape feeding apparatus. AMPEX CORPORATION. Sept. 19,1962 [Oct. 2, 1961], No. 35741/62. Heading G5R. In order to increase the speed with which tape search and rewind operations may be carried out, the tape is arranged in two concentric subcoils 14,15 spaced radially apart and is processed by a magnetic head arrangement 17 which is arranged to engage the tape in the space between the sub-coils only after the search operation is complete. The tape is fed from the outer sub-coil, which is the rewind coil, to the inner by rotating both the inner spindle 31 and the plate 32 carrying the couter coil, at different speeds. This is achieved by passing instructions from the control circuits 75 to the motors 71 and 72 which drive the spindle and plate respectively at different speeds through the pulleys 47 and 59, belts 46 and 58 and pulleys 45 and 35. A count of the rotations of the spindle and plate is maintained by means of the photo-electric arrangements 86, 87, the difference in the counts giving a unique indication as to which section of tape lies in the section between the two sub-coils. By programming the control circuits in accordance with the appropriate count the tape may be stopped at any required position. When the tape has been stopped it is necessary to bring the arrangement 17 downwards into operation to process the tape without crushing the tape. This is achieved by first lowering the pointed sub-arm 123, which will pass on one or other side of the tape, and then rotating the arm to bear against the outer sub-coil 15. The inner sub-coil is then rotated to take up the slack in the tape and leave it in a defined position held by the arm 123. The magnetic head arrangement 17 is then lowered, after which the arm 123 is returned to its original position so that the tape is held taut against the heads 107, 108, 109, and is positioned by the guide 106 and the capstan 111. The arm 17 is rotated so that the capstan 111 bears tightly against the outer sub-coil and this capstan is rotated by the motor 112 so as to draw tape from the inner sub-coil in order that it may be read. Fast winding and rewinding of the tape is always carried out with the arms 17 and 123 raised. In order to hold the tape firmly against the flange in the outer sub-coil, compressed air may be supplied from an apparatus 93 through holes 98 in the central spindle.

Filed: 1938-12-08
Abstract: 522,429. Distributing music. WIRED RADIO, Inc. Dec. 8, 1938, No. 35801. Convention date, Jan. 14. [Class 40 (iv)] [Also in Group XL] In a system in which different programmes are transmitted over, e.g., a power line 25, in the form of side-bands of suppressed carriers and in which a control frequency from which replacement carriers are derived is transmitted with the side-bands, any modulation of the control frequency arising during transmission is removed by combining it in a linear detector 34 with local oscillations 35 of different frequency, and of relatively-low energy level, selecting the sum or difference frequency, recombining this with the local frequency in a second linear detector 37 and selecting the original frequency by a filter 38. Since the local oscillations and the modulation frequencies are both weak relatively to the control frequency, the output of detector 34 will contain only combinations of the control frequency and the weaker frequencies and not combinations of the weaker frequencies with one another, and the sum or difference frequency selected by filter 36 will not contain the modulation. In the system shown, the carriers employed are all harmonic (30, 50, 60, 80 kc) of a crystal-controlled basic frequency of 10 kc and the control frequency is a higher harmonic (150 kc) of the same basic frequency and after the removal of modulation is passed to a submultiple generator 39 to produce replacement carriers corresponding to the suppressed carriers. Specifications 520,074 and 521,720 are referred to.

Abstract: 1,076,746. Detecting objects on a conveyer. SMERALOVY ZAVODY NARODNI PODNIK. Sept.2, 1964 [Sept.7, 1963], No.35834/64. Headings G1A and G1N. The presence of objects on a conveyer is sensed by a photo-electric, inductive, or radioactive detector 1, Fig. 1, which operates a switching device 2 each time an object passes, the switch device 2 (e. g. a transistor or a thyratron) being connected to a circuit containing a time constant R 2 C and a relay 3, which is arranged to operate only if an object remains opposite the detector for more than a predetermined period of time, indicating jamming of the articles on the conveyer. In the circuit shown (Fig. 1) a voltage U charges the capacitor C through a diode D to energize the relay, provided the switch 2 is open. The presence of an object closes the switch 2, and the capacitor C discharges (t 1 , Fig.2, not shown) through R2. The relay is de-energized only if the object remains long enough for the voltage across C to drop below the relay hold voltage (U<SP>1</SP>); otherwise, when the switch 2 opens, the capacitor C charges again, through the diode D, in a short time (t 2 ). If the diode is reversed and the switch 2 is normally closed, but opened by the presence of an object, the relay is normally de-energized and operates only if an object stops long enough for the voltage U to charge the capacitor C through the resistor R2 up to the required relay operating voltage.
