Title: Improved absorption refrigeration machine
IPC: F25B15/00
Filed: 1969-10-27
Abstract: 1,223,959. Absorption refrigeration system. TRANE CO. 27 Oct., 1969 [6 Nov., 1968], No. 52511/69. Heading F4H. An absorption refrigeration system utilizing lithium bromide as the absorbent and water as the refrigerant uses heat of high pressure steam or the like condensate from a first stage generator 18 to heat intermediate strength solution in or immediately prior to a second or lower pressure generator 20. The two generators, condenser 12, evaporator 14 and absorber 16 are positioned in a single shell 10 and a first heat exchanger 46 mounted in the evaporator has fluid from a heat load passing therethrough for cooling. A second heat exchanger 34 utilizing steam from a source 32 is mounted in the generator 18 which is at high pressure, and the flow of steam condensate passes therefrom to a heat exchanger 90 in the second generator 20, which is at low pressure, via a flow restrictor 36 for eventual recirculation through a conduit 91 to the steam source. Intermediate strength, partially concentrated absorbent solution passes from the generator 18 to generator 20 through a liquid conduit 64, heat exchanger 60 and conduit 66. Refrigerant vapour evolved by the heat exchanger 34 in the generator 18 passes into a heat exchanger 38 in the generator 20 for passage to the condenser 12 through a regulating device 40, whilst the refrigerant vapour evolved by the heat exchanger 38 in the generator 20 passes through a liquid eliminator 42 into the condenser 12 having a heat exchanger 28 from which the liquid flows to the evaporator 14 through an opening 44. In a modification, the heat exchanger 90 is positioned outside the second generator 20 to preheat the flow of intermediate strength absorbent solution prior to introduction into the generator.

Abstract: 1351579 Cathode-ray tube displays DEL MAR ENG LABORATORIES 23 Nov 1972 [9 Dec 1971] 54247/72 Heading H4T Recurrent signals, such as electrocardiograph (ECG) signals, recorded on a single track on a magnetic tape 100 (Fig. 1) are displayed, superimposed, on a cathode-ray tube 102 by employing the output of a play-back transducer 11 which "lags" in the direction of movement (left-to-right) of the tape, to deflection modulate a time base trace produced by sweep generator 17 when triggered by a trigger signal derived via amplifiers-filter 12 and delay multivibrators 13-16 from the output of a further transducer 10 which "leads" in the direction of tape movement. Fig. 2 shows the sequence of the steps employed, the amount of delay introduced between the leading edges of waveforms C and G, the latter triggering the sweep generator, being such that the ECG waveform A, from which the trigger signal is derived, is the same ECG waveform I actually displayed. Instead of employing a chain of multivibrators the required delay may be produced by means of an endless magnetic tape (Fig. 3, not shown) or magnetic discs (Fig. 4, not shown) on which the output of the transduced 10 is recorded by a recording transducer and then reproduced by means of an additional play-back transducer suitably spaced from the recording transducer to provide the required delay. An erase transducer positioned between the recording and play-back transducer erases each recorded signal. In these embodiments the delay means may follow, instead of precede, the circuit which produces the trigger signal.

Title: Braking systems for motor vehicles

Filed: 1971-11-24
Abstract: 1372398 Braking system ROBERT BOSCH GmbH 24 Nov 1971 [25 Nov 1970] 54485/71 Heading F2F A braking system for motor vehicles comprises a braking force regulating valve 13 interposed in the line between a pressure source and a brake cylinder, means for producing a signal proportional to the loading of the vehicle and means for producing a signal proportional to the angular velocity of a wheel of the vehicle. The regulating valve has a member 16 which carries two valve members 17, 19 the arrangement being such that the position of the valve seat 15 for one 17 of the valve members is controllable by a electromagnet 8 which is in turn controlled from a computer 4 which receives the aforementioned signals. As shown the valve 13 allows brake fluid to flow to the brake cylinder which is connected to an outlet 28, the brake fluid operating on a variable effective area diaphragm 22 to control the position of a valve seat 20 which in the "lipped" position of the valve co-operates with the valve member 19 of the member 16. The valve 15, 17 constitutes a brake venting valve which is opened by the electromagnet when a skid is sensed. The electromagnet may be separate from the regulating valve in which case the electromagnet operates a pneumatic valve so that pressurized fluid is allowed to work on the valve seat position controlling member (Fig. 2, not shown). The electromagnet may be coaxial with the regulating valve and the transducer provided for indicating the position of the movable valve seat (Fig. 4, not shown). In a further embodiment the pressures in the braking circuit upstream of the regulating valve and in the brake cylinder itself are monitored and signals proportional thereto fed into the computer for comparison (Fig. 6, not shown). The pressure in the vehicles pneumatic suspension may also be monitored. In a modification of the last mentioned embodiment the brake cylinder pressure in not monitored and during the brake cylinder exhausting sequence of operation the pressurized fluid escaping from the brake cylinder is conducted to the low pressure side of the piston of the brake cylinder to accelerate brake release (Fig. 8,not shown). Suitable circuits for computers to be used with the above constructions are described briefly with reference to Figs. 3, 5 and7 (not shown).
