Title: Improvements in or relating to apparatus for measuring quantity of heat transfer.
Inventor: WATSON PETER JORDAN
IPC: G01K17/16
Filed: 1966-09-14
Abstract: 1,179,911. Digital measurement. ENGLISH ELECTRIC CO. Ltd. 14 Dec., 1967 [14 Sept., 1966], No. 41109/66. Heading G4H. [Also in Divisions G1 and G3] The total heat transferred to or from a flowing fluid, e.g. in a heat exchanger, is computed from electrical measurements of the difference between the inlet and outlet temperatures and the rate of flow of the fluid. As shown (Fig. 4), the temperature difference is measured by two thermistors 22, 23 arranged at the inlet and outlet respectively of a fluid pipe, and connected in an A.C. bridge 102 whose unbalance voltage is proportional to the temperature difference and is fed, after amplification and rectification, to a comparator 104. The fluid flow rate signal is generated in a coil 107 associated with a magnet (not shown) rotating at a speed proportional to the fluid flow rate. This signal is clipped and differentiated and the resulting pulses 109a, having a frequency proportional to the flow rate, are fed to a bi-stable device 106. When the latter receives a pulse 109a it produces an output voltage 106a which starts a ramp generator 105, also connected to comparator 104. When the ramp voltage 105a equals the temperature bridge unbalance voltage 103a, the comparator 104 produces a pulse which constitutes another input to the bi-stable device 106, and terminates its output voltage 106a. Hence, the output from device 106 comprises a series of pulses 106a of frequency proportional to the fluid flow rate and duration proportional to the temperature difference, which is used to operate an AND gate 111 which transmits pulses from an oscillator 110 to the driving unit 112 of a stepping motor for the duration of the pulses. Thus a measure of the total heat transferred is obtained from a counter 113 driven by the stepping motor.

Abstract: 1496819 Computer controlled tunnelling machine GEBR EICKHOFF MASCHINENFABRIK U EISENGIESSEREI mbH 10 Oct 1975 [11 Dec 1974] 41546/75 Heading G3N [Also in Division E1] A tunnelling machine 1 uses laser alignment and computer control to produce a desired roadway 3 cross-section. The machine 1 works the heading face 2 using a getting tool formed as a cutting drum 4 mounted on arm 7 which is horizontally and vertically pivotable by hydraulic jack cylinder pairs 8, 9. The machine traverses roadway floor 11 by endless track 10 and picks up the debris with shovel 12 for rearward delivery through conveyor 13. A laser 14, Fig. 3, on the roadway passes its beam 15 to a receiver 17 which can be vertically and horizontally displaced by servos to ensure that the beam always hits the receiver surface centrally. Angular deviations of machine 1 with respect to beam 15 are measured and offsets around the machine longitudinal axis are detected by two gyroscopes, in machine casing 19, which respectively rotate about horizontal and vertical axes in the roadway cross-sectional plane. The measured outputs pass to a computer 20 which also receives desired profile data of roadway 3 from store 21 and signals proportional to the measured value co-ordinates of cutting drum 4, the latter being supplied by angle encoders 22, 23 associated with support arm 7 pivoting about axes 5, 6 and connected to counters 24, 25. The computer defines roadway cross-section units beyond which the drum 4 should not move and continuously adjusts these units in accordance with the signals from receiver 17 and the gyroscopes. The machine is controlled via AND gate 29 and electro-hydraulic control 32. The operator can pivot the arm across the face 2 as desired using manual control 27 but cannot go beyond the units set by the computer. Switch 21 can cut out the computer and allow complete manual control. The drum drills the tunnel in a series of horizontal sweeps Fig. 4 (not shown) as directed by a program in store 21. Alternatively Fig. 5, (not shown) the drum can start at the centre and work outwardly. The final cut is at reduced feedrate to reduce profile errors.

Abstract: 1410655 Safety belt frictional braking device TAKATA KOJYO CO LTD 14 Sept 1972 [18 Sept 1971] 42632/72 Heading A3V [Also in Division E2] A vehicle safety belt brake mechanism comprises at least one braking member 2 pivotable about a transverse axis relatively to the belt 1 and having a longitudinally curved braking face for engaging a face or a respective face of the belt to inhibit the advance of the belt when the withdrawal force is less than the frictional restraining force between the belt and the braking face or faces wherein the or each braking face extends across the belt face and is so longitudinally curved that when the or each braking member rocks forwardly any point of maximum engagement between the or each braking face and the belt face moves rearwardly with increase in the withdrawal force unless an angle between a line from the axes perpendicular to the belt and a line from the axis to the corresponding point of maximum engagement exceeds an angle whose tangent is equal to the coefficient of friction between the or each braking face and the belt face. The belt 1 passes between pivoted brakes 2, 2' mounted in a frame 3 in the form of a channel. The brakes clamp the belt under the pressure of a spring urged transverse element 12 which has side flanges 13 with projections which engage in grooves in adjacent end faces of the brakes, the element 12 is connected to a plunger 10 of a solenoid 8 secured to the frame 3 which is bolted to the vehicle frame. When a passenger occupies a seat a switch closes in the circuit of the solenoid to energise the solenoid and swing the brakes apart to allow the belt to pass freely therebetween. In an emergency an inertia switch opens, the solenoid is deenergised, the brakes pivot to grip the belt, as forward motion of the passenger tensions the belt, the brakes pivot further and grip the belt more tightly owing to the decrease in curvature of the braking faces. When the tension in the belt exceeds a predetermined value the belt commences to slip. In a modification, Fig 12 one of the brakes is a fixed plate 23, and the braking face of the brake 2' is roughened to increase the friction to inhibit slipping.

Abstract: 1,000,858. Magnetic core shift registers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 30, 1963 [Nov. 2, 1962], No. 42853/63. Heading G4C. [Also in Division H3] In a shift register in which through each pair of consecutive cores are threaded a first wire connected to a first current pulse source and a second wire connected to a second pulse source, the latter is triggered by a voltage induced in the second wire when the first core changes state due to the triggering of the first current pulse source and supplies a current to the second core in coincidence with current from the first current source so as to switch the second core's  state. As shown in Fig. 1, a first wire 2 is threaded through core R 1  three times and R 2  once so that when current source 1 is triggered a current of 3/2i, where i is the current necessary to change the state of the core R 1  from " 1 " to " 0," flows through wire 2 so that if core R 1  is initially in the " 1 " state it is changed to a " 0 " state. The core R 2  remains in its " 0 " state since it is only threaded once. The voltage induced in wire 4 causes the emitter of transistor 6 of pulse generator 3 to become positive and the transistor to conduct until the core of feed-back transformer 7 saturates when the transistor again becomes non-conductive. The current pulse of ¢i from generator 3 together with the current pulse from generator 1 are sufficient to switch the state of core R 2  from the " 0 " state to the " 1 " state with the result that the information stored in core R 1  is transferred to core R 2 . The arrangement of Fig. 1 may be used in the quadruple shift register of Fig. 2, in which pulses from counter T are successively applied to terminals 11 to 16 and blocking oscillators 3 are triggered by the appropriate core changing state as above.
