Abstract: 1309050 Line printers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 July 1971 [17 July 1970] 33201/71 Heading G4H [Also in Division B6] In a line printer variations in the print intensity upon the visual record caused by differing surface areas of the various printing characters are accommodated by varying the time during which a constant current is allowed to flow through the associated hammer energizing coils. The printer is of the type having a rotatable drum having a plurality, e.g. 16, axial lines of type characters each line having, e.g. 20 print positions of the same characters wherein one or more hammers may be activated on any one line and activations on all lines produces the complete line of print. As shown, data corresponding to a print operation is fed to and stored in a shift register consisting of two portions 17<SP>1</SP> and 17<SP>11</SP>, the former comprising 20 positions each corresponding to one of the hammer coils L 1 -L 20  and the latter having 4 positions and providing a code determining the particular tone. Upon insertion of the word in the register, a stepping motor 12 is caused to rotate the print drum and a photo-electrically sensed position encoding scale 18, the output of which is fed to a comparator 20 together with the word stored at 17<SP>11</SP>, and also to a device 30 which provides an output on 1 to 16 lines l 1 -l 16  in accordance with the code sensed. The lines l 1 -l 16  are grouped into groups of 4 by OR gates G 1 -G 4  and passed to 4 AND gates P 1 -P 4  which are enabled by a coincidence signal of the comparator, which also stops the motor 12. The groups each correspond to those characters requiring similar hammer pressure for satisfactory printing each group requiring a different pressure, and the output from one of the gates P 1 -P 4  causes activation of a corresponding monostable T 1 -T 4  each having different pulse lengths. The output pulse is taken to enable AND gates g 1 -g 20  via which particular coils are energized according to the position of one or more "1's" in the register 17<SP>1</SP>. Constant current generators I 1 -I 20  supplied from a storage capacitor C are employed and the duration of the current pulse in any event is less than the flight time of the hammers and hence each will possess a momentum proportional to the pulse duration.

Abstract: 1482774 Selective signalling ROBERT BOSCH GmbH 31 July 1974 [1 Aug 1973] 33707/74 Heading G4H A plurality of loads are controlled at respective times and signal their states at respective times. In a motor vehicle, a transmitter includes a clock-driven ring counter which scans a plurality of control switches to send respective control pulses on a common line to each of a plurality of receivers. The series of control pulses is preceded by a start pulse of larger amplitude on the same line (or on a separate line) also produced from the ring counter. In each receiver, the start pulse triggers a multivibrator of adjustable period characteristic of the individual receiver. The end of this period is detected by a differentiator to enable a gate to pass a coincident one of the control pulses if present, to switch a load, e.g. lamp. A storage member may be provided to maintain the load switchedon at least until the corresponding point in the next cycle of the ring counter. The differentiator output also passes through a photo-sensitive resistor responsive to the lamp to signal its state back to the transmitter for display on a lamp selected by the output of the corresponding control switch (if actuated).

Abstract: 1,126,912. Mixing fluids in flow. CHLORINATION EQUIPMENT Ltd. 29 July, 1966 [6 Aug., 1965], No. 33828/65. Heading B1C. In apparatus for chlorinating water, the water flow (from right to left as depicted) through an injector 6 establishes a pressure difference in pipes 7, 8 which actuates valve 10 to close vent 13 and open pipe 11 to the reduced pressure (in excess of 45 inches water gauge) of the venturi throat. Constant pressure regulator 17 is adjusted to close when the vacuum in pipe 21 and gas flow meter 22 rises to this figure. Chlorine gas under pressure is supplied through pipe 3, chamber 29, restrictor' 24 and flow meter 22 to pipe 11 and thence to the venturi throat. A spring controlled adjustable regulator 23 can be adjusted to maintain the pressure in chamber 29 and upstream of restrictor 24 at a selected figure between 22 and 45 inches w.g. vacuum, and the proportion of chlorine added will depend on the pressure drop across the restrictor between the selected pressure upstream, and the constant 45 inch w.g. vacuum downstream of the restrictor. A relief valve and vacuum breaker 30 vents the system to vent 13 if excessive pressure builds up if gas is fed when the injector is not working, or if the injector is operated while the gas is off. A return valve 14 prevents back-flow of water into the system. In a modification (see Fig. 2, not shown) the device 30 is replaced by a pair of separate spring-loaded valves, and there is an additional non-return valve in the pipe 11.

Abstract: 901,210. Determining liquids levels. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 6, 1960 [Oct. 6, 1959], No. 33861/59. Class 37. In a manometer or tilt gauge, variation in length of a column or columns of liquid 2, Fig. 1, varies the impedances between two pairs of electrodes 5, 5<SP>1</SP>, 6, 61 forming two arms of a bridge circuit, Fig. 2. The output of the bridge is applied to a calibrated meter. The electrodes may be bare wires immersed in the liquid or may be strips attached to outside surfaces of the tube 1. Alternatively, the tube may be conductive with the other electrode arranged centrally within it. In one embodiment, a manometer may have an additional U tube secured to it so that the latter serves to replace the bridge resistors R 3 , R 4  can thus compensate for errors due to the tilting of the manometer. In another embodiment, the output voltage from the bridge of the first manometer is fed to the input terminals of a bridge for a second manometer, the latter being subjected to corresponding pressures. The output from the second bridge then varies according to the square of the pressure difference, this procedure may be repeated to produce the cube of the pressure difference. In another arrangement for producing a signal varying with the square of the pressure difference, the frequency of the output voltage from the bridge is modified and the resultant signal fed back into the input of the bridge, the new output voltage being measured after selection by a frequency responsive circuit.

Abstract: 445,494. Brakes. PIGANEAU, G. P., 152, Boulevard Malesherbes, Paris. Nov. 26, 1934, No. 33936. Convention date, Nov. 27, 1933. [Class 103 (i)] A brake is operated by a centrifugal device 2 which engages the brake at one end and at the other end a member operated by the driver so that the driver can transmit manual effort to the brake through the centrifugal device. To apply the brake the driving roller 3 of the centrifugal device in casing 2 is brought into engagement with driving means such as a brake drum 4 and the centrifugal weights 7 move radially outward and by inclined surfaces act on rods 11, 13. Rod 11 moves out to operate brake lever 12 and rod 13 is held stationary by a spring-pressed plate 14. When a certain braking pressure has been attained, the springs 15 yield and release the brake. The compression of the springs may be increased by hydraulic transmission acting on a piston 16 against which the springs 15 abut so that the brake is released at a higher braking pressure. The casing 2 is turned in an eccentric mounting to engage the roller 3 and is moved by the brake pedal which on further movement engages a plunger which acts on the hydraulic transmission compressing the springs 15. The plunger may be moved by a hand-operated screw. Specification 400,418 is referred to.

Abstract: 1,012,900. Yarn tension device. J. SAARE. June 4, 1964 [March 5, 1963], No. 34027/62. Heading D1D. A yarn tensioning and tension regulating device comprises two moveable guide eyes 18, 19 supported by depending arms 17 free to swing about horizontal pivots, a fixed guide eye 24 disposed above and between the moveable eyes and means for conducting the yarn y to one of the moveable eyes e.g. 19 and downwardly from the fixed eye 25. As shown each arm 17 is carried by a horizontal beam pivoted in the wall of sleeves 13 which pass through and are rotatable in holes 12 in a horizontal plate 11. The sleeves have arms 14 each of which has a spring urged member 16 to engage teeth 15 in the edge of plate 11 and thus hold the arm 14, sleeve 13 and pivot beam at a desired and adjustable orientation. The device is normally set up with the pivotal axes of arms 17 meeting forwardly of the device and with yarn passing from eye 19 to eye 18, then to eye 25 mounted by an arm 24 on a back plate 10 and finally downwardly to a roller 26 also mounted on back plate 10. The downward run of the yarn passes in front of and in contact with the run of yarn between eyes 18, 19 so that when the tension in the incoming yarn rises and the eyes 18, 19 move towards each other (and thus towards the back plate 10) the substantially horizontal run of yarn tends to move out of contact with the substantially vertical run to decrease the tension applied at the point at which the runs cross and thus regularise the tension in the outgoing yarn.
