Filed: 1970-11-03
Abstract: 1324800 Starting diesel engines AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT 3 Nov 1970 [7 Jan 1970] 52335/70 Heading H2H A circuit for starting and stopping a diesel engine comprises a battery 31, a main switch 32, a heating circuit 33, a circuit 35 controlling a starter 36 and an electromagnetically locked, manual control member 60 for maintaining a valve 58 in a fuel supply conduit 59 open so long as the main switch is in a "running" position. When the switch 32 is placed in its "running" position, contacts 38, 39 are engaged thereby energizing the coil 62 of the electromagnetic lock and depressing a plunger 61 against the member 60. A relay coil 43 is also energized via the switch of a voltage regulator 56 for an alternator 55 so that a switch 41 is closed and heater plugs 48 start to warm up. After a certain time a bimetallic strip 49 heated by a resistor 47 closes a contact 50 thus illuminating a lamp 51. When the number 60 is pulled outwardly the plunger 61 enters a notch 60a to lock the valve 58 open and a contact 63 is closed so that on moving the switch 32 into its third position in which the contact 38 engages contact 40 the starter 36 is energized. When the engine starts the regulator 56 breaks the supply to the relay coil 43 so that the heater plugs are cut off from their supply and an oil pressure switch 53 opens to extinguish a lamp 54. If the starter is not actuated after moving the switch to the "running" position, a bimetallic strip 45 opens a contact 44 to deenergize the relay coil 43 and cut off the supply to the heater plugs. On returning the switch 32 to its first or "stop" position the coil 62 is deenergized and a spring returns the member 60 to its valve closing position.

Title: Physiological measurement display system
IPC: G01K1/02
Filed: 1972-11-16
Abstract: 1417148 Analogue - to - digital conversion MONITRON INDUSTRIES Inc 16 Nov 1972 [17 Nov 1971 19 Nov 1971] 53021/72 Heading H3H In monitoring a physiological condition of a patient a blocking oscillator is controlled by the monitored condition to generate bursts of R.F. which are picked up by a receiver including a demodulator and pulse-shaping means to produce pulses at a rate corresponding to the burst rate of the R.F. bursts and means for counting the pulses that occur in a selected period of time. Overall system.-The tuning coil of the blocking oscillator also acts as the aerial, coupling between transmitter and receiver being by the extreme near field transformer effect. Received bursts are amplified (Fig. 6, not shown) and the dominant frequency selected by demodulator (84) and converted to a sinusoidal waveform by a band-pass filter (86). A voltage controlled square wave oscillator (100) is started oscillating at a frequency higher than the burst rate upon manual actuation of a "read" switch (122) and is swept downwards until it becomes phaselocked to the output of the filter (86). The frequency of the oscillator (100) is digitized as follows. A/D conversion. Fig. 8.-Upon actuation of "read" switch 122, after a delay to allow phaselock to occur, an initial zero-offset number is loaded into counter 136 and counters 130, 134 are reset to zero. The phase-locked pulses are gated through gates 222, 226, 228 into counter 136 for a time interval defined by counting clock pulses from 180 in counter 130 until a decoder 184 detects attainment of a particular count, whereupon, provided counter 134 detects that the number of phase-locked pulses is within set range limits, the count in counter 136 is transferred to the indicator 166. As shown, the first 87 phase-locked pulses are not counted, gate 226 being enabled only after counter 134 has registered the 88th pulse. Other ways of obtaining suitable zero offsets are described (Figs. 10, 11, not shown). In a modification, Fig. 13 (not shown), compensation for non-linearity of a temperature to burst frequency transducer is afforded by feeding both the phase-locked pulses and the clock pulses to the timing counter (406) towards the end of the counting time period to vary it in such a way as to provide the desired compensation. Also in this embodiment, the A/D conversion and display are blocked if phase-lock is lost. The monitored condition may be temperature, blood pressure, pulse rate or E.C.G.

Filed: 1974-12-09
Abstract: 1451579 Trailer over-run brakes; internal shoe drum brakes HAHN FAHRZEUGBAU GmbH 9 Dec 1974 [28 Dec 1973] 53066/74 Heading F2E An over-run brake for trailers including an internal shoe drum brake 7, Fig. 1, operable by a hand-brake lever 3 or a draw rod 2 and member 4 through a floating expanded device 11, firm support for the primary shoe 8 being provided during forward travel 19 and the brake action being almost eliminated in the case of reverse travel 22, is characterized in that the ends of the shoes remote from the expander are supported on components including a pivot cam 25, Fig. 2, which in forward travel abuts a first fixed stop 28 as a result of the moments exterted on the shoes, and in reverse travel pivots to enable the secondary shoe 9 to move (circumferentially) a spring member 40 being inserted between the expander device 11 and the axis of the pivot cam; a second fixed stop 48 is provided by the pivot cam to enable a greater expansion of the shoes by the hand-brake lever 3. In operation, during over-run braking, the primary shoe 8, acting at point 39 of cam 25, Fig. 2, urges the latter clockwise about its axis of rotation 35, to abut first stop 28, because of the direction of travel 19, Fig. 1, of the drum 12, despite the greater lever arm 44 of the counterclockwise moment of the secondary shoe 9. Spring 40 is compressed. During reversing, on account of the opposite directon of rotation, 22, of drum 12, counterclockwise rotation by the secondary shoe 9, including the effect of the greater lever arm 44, prevails, and the cam 25 pivots to the position of Fig. 3. In this position lines 46, 47, of cam 25 constitute the second stop, and, the lower end of shoe 9 being nearer fixed housing 24 than in Fig. 2, the shoes are substantially ineffective. With the trailer stationary, hand-brake-lever operation produces equal forces at the shoes, so the greater leverage by shoe 9 pivots cam 25 to the Fig. 3 position again, after which the leverage provided by hand-brake-lever 3, which is greater than the leverage of draw rod 2 and member 4 in over-run braking, on transmission member 5, Fig. 1, serves to ensure maximum braking effect.

Abstract: 1,202,887. 887. Automatic control systems for rolling mills. NIPPON KOKAN K.K. Nov.24, 1967 [Nov.26, 1966], No.53632/67. Heading G3R. In an automatic shape and thickness control system for a rolling mill of the type wherein a roll bending device is provided and wherein an electrical signal representative of roll force is used to adjust the screw-down at the rolls, the sensed roll force signal is compensated by a signal representative of the reaction force due to the roll bending device so that a signal equivalent to the actual roll force is always obtained for various rolling conditions. As shown an oil pressure detector 6 for the hydraulic cylinder 3 of the roll bending device provides a signal indicative of the bending device pressure, which signal is converted to an electrical signal by a power source 9 for application to a converter 7. This converter derives an output signal in accordance with the equation Q=KP where Q is the bending reaction force, P is the sensed bending device pressure and K is a constant  dependent on the rolling conditions, e.g. the size, constitution and temperature of the workpiece and the type of roll bending device. Such values of K may be calculated in advance and stored in a memory of the converter 7, such calculation, storing and selecting being effected by the rise of an electronic computer, tape or punched card and a manual dial. Thus a value of K is selected for a particular rolling operation and the converter 7 produces an output signal "q<SP>1</SP>" equivalent to the bending device reaction signal "q" which is included in the signal "(f + q)" provided by the load cell sensor 5 at the rolls. Summation of the signals "(f + q)" and "q<SP>1</SP>" thereby removes the reaction signal "q" and provides a signal "f" representative of the actual rolling force, which signal may be applied to an oscillator 8 forming part of a conventional control system for adjusting the screw-down of the rolls, Fig. 9 (not shown). The calculation of the constant K for various arrangements of rolls and bending devices is discussed, Figs. 3 to 8 (not shown).
