Abstract: 1,250,637. Dressing grinding wheels. LANDIS TOOL CO. 23 Dec., 1968 [26 Dec., 1967], No. 60938/68. Heading B3D. A method of dressing a grinding wheel 27, Fig. 4, comprises the steps of traversing a rotating dressing roller 18 across the peripheral face of the wheel in one direction, stopping the rotation of the roller, and traversing the now stationary roller across the peripheral face in the return direction to perform a finish dressing operation. In a machine described for carrying out the method the roller 18 is mounted on a carriage member 30 for movement across the wheel 27 and the member 30 is carried by a dresser slide 45 for movement of the roller. 18 towards and away from the wheel. The movements are controlled by piston and cylinder devices 32, 33 and 47, 46 respectively and by contact of a follower 50 with a profile bar 51 to move the roller 18 across the wheel and around the comers R1, R2 thereof, Fig. 3. The roller 18 may be driven by a motor or held non-rotatable by a brake acting on the motor shaft. A solenoid SOL 30, Fig. 4, controls actuation of the motor brake, and solenoids SOL 33 and SOL 34 control the flow of a pressure fluid to cylinder 33. In operation of the machine the roller 18 is stationary in a position A, Fig. 3. After a predetermined number of rotations of the wheel 27 have been counted, a contact in a control circuit is closed which causes the solenoid SOL 30 to be energized to release the motor brake and causes the solenoid SOL 33 to be energized to cause movement of the roller 18 from A to B. At B a time relay in the control circuit causes the motor to be energized so that the roller 18 is rotated as it passes across the face of the wheel from B to G, and subsequently around the comer R2 of the wheel to C. When position C is reached a limit switch 30 LS is operated by an abutment member 60 on slide 45 to stop the motor and operate the brake. The roller 18 is then returned to position G with the roller held non-rotatable, and the solenoid SOL 34 is then energized to move the roller 18 across the face of the wheel 27 to position B. At B a limit switch 29 is operated by an abutment 56 carried by the member 30 to cause the brake to be released and the motor to be driven as the roller passes around corner R from B to H. At H the motor is stopped and the brake applied. The roller is then returned to position A. Coolant fluid may be fed between the roller and wheel during dressing. The motor brake may be omitted.

The time switch device enables a charging period of the storage heater only in the latter portion of a low-tariff period, whether day or night, to reduce heat radiation losses outside the period of use since the normal low tariff period is of too long duration, and the consumer may adjust the heat requirement from the heater in accordance with prevailing or expected temperatures and so enable sufficient heat to be stored. The temperature timer is combined with a manually-settable thermostat to enable automatic changing over from a day to night temperature and vice versa after individual programming. The intake period time switch comprises a period selector knob 3, a drive wheel 25 and switch 8 for manual operation of the day tariff period being arranged concentrically within a recess of the knob 3. The indicator and preselector for adjustment of the timer for night time, lower temperature operation is arranged in an aperture 13 and comprises a clock 14 with settable hands 15, 16 and a calibrated dial 18 for setting the lower temperature period which is set thereon by pointers 20. Knobs 21, 22 allow pre-selection of the day and night temperatures respectively. The knob 3 is rotatably mounted on the drive wheel 25 supported on a hollow stud 27 secured to a back plate 26 intermediate which an adjustable ratchet is arranged comprising detent pins 28 and compression springs 29. Dial 6 is mounted on an extension 31 of the wheel 25 to show the intake period. A cam 32 on the selector knob moves towards a switch cam 33 on the wheel to switch on the storage heater by actuating a star wheel 34 through a shaft 35A. A synchronous motor 39 drives the wheel 25 through gearing 40. The switch 8, operated manually by a crossbar 9, is mounted for rotation in the stud 27 and has a pin 43 actuating a pawl 44 guided by a pin 45. to engage a ratchet wheel 46 on a second control shaft 35 on which is mounted a switchcam 36 to open or close a contact arrangement 37. The temperature-changing timer and thermostat are as described in Specification 1,202,654, being driven through a common timing shaft 47 of the motor 39.

Abstract: 1304841 Fluidic detectors WESTINGHOUSE BRAKE & SIGNAL CO Ltd 22 Jan 1970 [22 Jan 1969] 3501/69 Heading G1M [Also in Divisions F1 and G4] A fluid pressure operated detector for detecting the presence of a surface 18 when moving through a point in a region comprises means to direct two fluid flows into the region in distinct directions 12, 14 at least one flow being deflectable by the surface when present at the point, the detector including means 11, 14 responsive to a state of fluid flow in a direction 17 other than either of said distinct directions which state varies with the presence and absence of the simultaneous deflection of the deflectable flow and interaction between the two flows. As described the presence of a lidless container in a series of similar containers on a conveyor belt is detected by fluid-flow devices detecting the presence or absence of lid and body separately the results of the detections being used by fluid logic circuits (Division F1) to cause alarm signals after each lidless container is detected and to stop the belt after three lidless containers have been detected.  In Fig. 1, air flow 16 is deflected by lid 18 to interrupt balanced interacting opposed air flows issuing from nozzles 11, 12, the reaction back pressure detected at branch conduit 14 decreasing as the balance of interacting flows is upset. In Fig.2 two opposed nozzles (34, 35) in Fig. 3, (not shown), are in block 21 (31) and nozzle 26 replaces conduit 13 to look for lids on containers 25 on conveyor 23. Container bodies 25 are detected by an arrangement in which two opposed nozzles in block 22 producing opposed, balanced jets are on one side of conveyor 23 and nozzle 27 is on the other side of the conveyor so that the jet from nozzle 27 engages the opposed jets (without deflection) which thus produce a reaction back-pressure only when a container body interrupts the detecting air flow from nozzle 27. In Fig. 5 a flow of fluid issuing from conduit 51 is received in an orifice in conduit 52. Fluid flowing from a pair of conduits 53, 54 interact at 55 and is dissipated unless a lid is present when the resultant flow is directed upwards 57 to interrupt the flow from 51 to 52 providing an indication that a lid is present. In Fig. 7 the upward flow resulting from impingement on a lid of two flows is collected in 72 and amplified, 73, before passing to choke 74 and to fluid logic circuit via 75. To prevent dust entering collector 72, Fig. 9, a stream of air may issue from a branch 77; because of the relative width and lengths of conduits 78, and 76, the flow issues through 76 unless flow is being collected by 76 when flow takes place along 78 to turbulance amplifier 79 and thence to diaphragm amplifier 73. The response of amplifier 73 is reversed in this modification and is inverted using an OR/NOR gate to provide output 75 suitable for feeding to the circuit of Fig. 8 (not shown). Reference has been directed by the Comptroller to Specification 1192778 and 1223148.

Abstract: 1307356 Controlling burners UNITED GAS INDUSTRIES Ltd 26 Feb 1970 [27 Feb 1969] 10577/69 Heading F4T In a gas flow control device, a valve controlling gas flow has an operating solenoid 2 in series with a gate controlled solid state switch 4 across an alternating current supply so that when the switch 4 is closed the solenoid is energized holding the valve open by half-wave rectified current, a smoothing capacitor 6 being connected across the solenoid and a signal being applied to the gate of the switch to keep it closed while the valve is required to be open. The switch 4 is preferably a thyristor. If the thyristor is short circuited, a large current flows through the diode 8 blowing a fuse 10. The diode 8, provided to suppress transients when the solenoid is de-energized, may be omitted, in which case short circuiting of the thyristor 8 causes A.C. to be applied to the solenoid 2 which is not able to open the valve because it presents a greater impedance to A.C. than to half-wave rectified A.C. A device for the detection of a flame at a burner, incorporating a gas flow control device according to the invention, is shown in Fig. 2, in which the flame, when present acts as a diode to cause triggering of the thyristor 32 to allow current to flow through solenoid 30 to keep the gas valve open. -
