Title: Improvements in or relating to printing floor coverings or the like
IPC: B41F1/10
Filed: 1929-01-14
Abstract: 304,237. Armstrong Cork Co., (Assignees of Brinton, W. P.). Jan. 17, 1928, [Convention date]. Platen presses.-A machine for printing linoleums, felt, or piece goods, in which the material to be printed is fed in web form intermittently through a series of block machines comprising blocks 5 - - 9 reciprocated vertically by cams 11<a> and selectively controlled by hooks 12 capable of holding certain of the blocks out of operation, is so constructed that the blocks 6, 7, 8 are built up of sections which are controlled by selective mechanism so that printing may occur from certain of the sections only, thus giving greater variations in the patterns which can be printed and enabling a variety of patterns to be printed with few printing blocks. Instead of employing a single block as 13, Fig. 1, blocks may be used divided transversely into two parts 16, 17, or three parts 19a, 19<b>, 19<c>, each part coacting with a separate different colour compartment of inkducts 18, 20, or with single colour ducts. The blocks may be divided longitudinally as 21b, 21<c>, or both transversely and longitudinally as 23<a> - - 23<d>, 25<a> - - 25f, 27<a> - - 27f, the ink ducts being divided transversely into corresponding sections. To control which of the blocks are brought into printing operation, the blocks as 35, Fig. 5, are carried by pads 34 mounted on guided rods 39 pressed upwards out of printing position by springs 40 and depressed into printing position when desired by cams 45<a>, 45<b> on shafts 45, 46 geared together and rotated intermittently by gearing from the shaft 51 of a disc 52 fitted with pins 53 which are engaged in sequence by a pivoted hook 69 operated from an oscillating lever 60 freely mounted on the shaft 51 of disc 52. The hook 69 is spring-controlled and pivoted at the junction of a lever 67 with a link 65 pivoted to lever 60. The lever 60 is connected to a link 61 pivoted to a fixed bracket 63, and the disc 52 is rotated to the extent of a tooth at each reciprocation of the printing-block, reverse motion of shaft 51 being prevented by a pawl and ratchet. The cams 45a, 45b are designed to bring the required parts of the printing block into action to print the particular pattern desired. Instead of controlling the printing blocks by cams, they can be 'controlled electrically by employing a torque motor 73, Fig. 8, geared to a segmental lever 74 connected by a link 75 to levers 76, 78 which act on the case 79 of a printing-block 72b normally raised by springs 82. An intermittently rotated shaft carries a contact 85 for closing the circuit from the power main to motor 73 by contacting with studs 86. To vary the design a hand-switch 87 is arranged at each stud 86 so that by opening these switches printing will not take place. These switches 87 are set in accordance with the pattern to be printed.

Title: Improvements relating to metering or relay systems
IPC: G01R17/08
Filed: 1930-01-14
Abstract: 344,137. Current meters ; protective cut-out systems. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London.-(Assignees of Lenehan, B. E. ; 90, Berkeley Avenue, Bloomfield, New Jersey, U.S.A.) Jan. 14, 1930, No. 1359. [Class 37.] A meter or relay system comprises a device responsive to power or other quantity of the line, contacts and a counter-torque producing member operated thereby, a thermionic tube energized by the closure of the contacts actuating the meter or relay and counter-torque member. As shown, applied to a remote metering or relay system, a Kelvin balance is employed to vary the magnitude of the current actuating the distant meters &c. The coils 11 .. 16 of the balance are connected to the mains C and respond to power &c. values, the beam contacts 18, 19 closing, short-circuiting resistor 25, and permitting increased current to flow to the indirectly heated cathode of the valve 22. A beam-restoring or counter-torque producing coil 20 in circuit with the meter or relay 27 opens the contacts 18, 19 when the anode current rises sufficiently. The resistor 25 is again inserted and the meter &c. current slowly reduced. So long as the load remains on the circuit C, the beam oscillates and the interval of engagement of the contacts increases with the load. Owing to the time delay in heating the cathode of the valve 22, the meter &c. current remains substantially constant. Alternating or continuous current supply 26 may be provided for the valve 22, a filter circuit 28 being included in the former case.

Title: Improvements in measuring the length of webs
Inventor: MCFARLANE IAN DUNCAN
IPC: B65H26/06
Filed: 1969-01-10
Abstract: 1,242,335. Measuring length. WIGGINS TEAPE RESEARCH & DEVELOPMENT Ltd. 6 Jan., 1970 [10 Jan., 1969], No. 1591/69. Heading G4H. In a method of, and apparatus for, measuring the length of a textile or paper web, the web 1 is passed over a roller 2, carrying a magnetic mark 13, the passage of which is detected by head 12. The passage of mark 13 causes counter 8 to start counting pulses from pulse generator 4 and opens gate 7 to allow pulses through. When the count in counter 8 reaches a preset value (determined by the diameter of roller 2), the gate 7 is closed and the counter reset. Thus the number of pulses passed by gate 7 per revolution is proportional to the roll diameter and hence the length of web. The pulses are added at 16 to give total length in arbitrary units, divided by a scale constant in 17 to give length in desired units and the length recorded at 18. A photocell 19 detects the presence of the web and closes relay 23 if the web breaks.

Title: Improvements in pistons
IPC: F16J1/04
Filed: 1928-01-17
Abstract: 313,893. Marks, E. C. R., (Bohn Aluminum & Brass Corporation). Jan. 17, 1928. Pistons. - In a piston in which expansion of guiding portions 10 of the skirt is controlled by means of struts 12 of nickel-steel or other relatively inexpansible material, any desired rate: of expansion is obtained by the employment of different nickel contents in the steel of the struts, the distance apart of the struts and their length. The expansion of the point A relatively to the point C is produced by the expansion of the slipper between A-B, represented by AG and the expansion of the strut, represented, for one strut material, by GH and, for another strut material, by GL. The resultant expansions AH, AL have diametral components AI, AM, to which are added IK, MO, representing the expansion of the skirt between the ends of the struts and the periphery of the skirt. The distances between the ends of the struts and the periphery of the skirt, may be increased by the employment of pillars 14, Fig. 6, to which the struts are attached. A single diametral strut may be employed. Specification 268,399 is referred to.

Title: Electronic temperature control circuit
IPC: G05D23/20
Filed: 1959-01-16
Abstract: 877,012. Automatic temperature-control systems. REGULATOR A.G. Jan. 16, 1959 [Jan. 17, 1958], No. 1679/59. Class 38 (4). In an automatic temperature-control system, heating of a space is controlled by a transistor amplifier having a thermistor in its input circuit, both the thermistor and an amplifier transistor being temperature responsive to influence the control system in the same sense. In Fig. 1 air supplied through a conduit 13 to a room 11 is heated by a hot-water heat exchanger 15. A thermistor 27 responsive to the temperature of the room produces a direct voltage which is amplified by a transistor 25 the output of which energizes a relay 19. The arrangement is such that a rise in room temperature affects both thermistor and transistor in such a sense as to increase the energization of relay 19 until, at a temperature determined by the setting of a rheostat 35, relay 19 operates a solenoid valve 17 to cut off the supply of hot water to heat exchanger 15. Thereafter room temperature is maintained constant by intermittent operation of relay 19. Modifications are described in which (a) resistor 35 is either outside the room or omitted altogether; (b) a thermistor 27 is either arranged in a bridge circuit or replaced by a resistor which is not temperature responsive ; or (c) a further transistor also responsive to room temperature provides a second stage of amplification.
