A spray head for a paint or insecticide dispenser having a reciprocating pump or a pressurized container comprises an integrally-constructed body 10 formed with a cylindrical blind socket 12 for receiving a liquid supply conduit 13, and including a recess 14 which communicates with the conduit 13 through passages 16 and oppositely directed outlet nozzles 16a, 16b, the base of the recess having a ridge defined by intersecting concave deflecting surfaces onto which the liquid from the outlet nozzles 16a, 16b impinges at an acute angle or tangentially. The concave surfaces are defined laterally by diverging walls (17), Fig. 2 (not shown) which extend from the ends of the nozzles 16a, 16b to the respective ends of the ridge. The surfaces may be of smooth configuration, causing the sheets of fluid formed thereon to impinge and form a fan-like discharge, or grooves (151), Fig. 4 (not shown), may be formed in the surfaces, the grooves of the two surfaces either being in register, Fig. 5 (not shown), or at least partially out of register, Figs. 4, 6 (not shown), to form spray patterns of varying widths. The surfaces may be adjustable relative to one another to vary the spray pattern. The surfaces may be partially smooth and partially grooved.

Abstract: 914,998. Measuring electrically. SARGROVE ELECTRONICS Ltd. April 26, 1961 [June 17, 1960], No. 21342/60. Class 40 (1). The readings of a number of variables are signalled to a remote point by causing each of them to produce a low D.C. voltage controlling the amplitude of a corresponding R.F. oscillator output. All the R.F. outputs are then fed through a coaxial line to a common remote wide-band amplifier and then to selective receivers each tuned to the appropriate frequency so that the readings of each of the variables may be indicated. In the arrangement shown in Figs. 2 and 3 current transformers 1a-1c provide a low voltage A.C. output representative of the condition in a threephase line. These outputs are rectified and smoothed as at 4a, 5a and used to control the amplitude of a crystal-controlled oscillator 9a. All the outputs are then fed through a coaxial line 6 to double crystal units 13a, 13d. The outputs of these units are amplified, 16a-16d, detected at 17a-17d and recorded at 14a- 14d. Fig. 4 shows an arrangement for controlling the oscillator output in which the D.C. signal from the condition to be measured is used to control the output of a transistor 19 acting as a buffer between oscillator 18 and coaxial line 6. The D.C. voltage controls a third winding of a transformer which has a stepped down ratio to the impedance of the coaxial line. In a further arrangement (Fig. 5, not shown) the D.C. voltage controls a variable Á valve between the oscillator and the coaxial line.

Title: Bentilator patient monitor
IPC: A61M16/00
Filed: 1975-05-21
Abstract: 1478767 Monitoring the respiration of a patient using a ventilator HEWLETT-PACKARD CO 21 May 1975 [17 Oct 1974] 21834/75 Heading G1N(E) In a device for determining a continuous measurement of the amount of the gas volume expired by a patient who is connected up to a ventilator to aid the patients respiration, a signal E A , from circuit 27, is derived that positively indicates that the patient is exhaling. This signal is used to gate 43 gas-flow signals F L . from circuit 39, so that only the gas-flow during expiration is monitored. The measurement signal eventually emerges from a D/A converter 59. The device is intended to eliminate the monitoring of the gas volume that leaks through a partially closed ventilator expiration valve (15), Fig. 1 (not shown), during inspiration. The gas-flow through the expiration valve and the mouth pressure, circuit 25, of the patient are used to obtain an indication of the resistance of the expiration valve. That is, a comparator 79 investigates when F V  R T #P V ; where F V  is the gas-flow through the valve; RT is a pre-set threshold valve resistance, and P V  is the pressure across the valve. P V  is directly related to the difference between the mouth pressure at the end of expiration PEE and the real time mouth pressure P M . Thus, the gated digital gasflow rate signals from gate 43 are fed to a series of counters 55, 56. The counters are reset after each expiration and their value transferred to a register 57 by a signal L-R from a pulse rate threshold logic circuit 41, also Fig. 3b (not shown). The output of the register 57 supplies a D/A converter 59 connected to an indicator (not shown), which shows the analogue expired gas volume EGV. The EGV signal may also be supplied to an alarm system 54 that is provided with pre-set thresholds to activate an alarm when the expired gas volume is below a pre-set threshold. The expiration rate, from circuit 53, and the maximum and minimum mouth pressure signals MXP, MNP, from circuit 25, are also fed to the alarm system 54, to activate alarms when the respective signals drop below corresponding preset thresholds. The circuit shown in Fig. 2 is explained in great detail in the description with the aid of a waveform diagram Fig. 3 (not shown), including a modification Figs. 4 and 5 (not shown), designed to overcome the effects of noise when the signals are low. The modification replaces the comparator 79 by a circuit involving two threshold valve resistances, instead of one, and utilizing a resulting "hysteresis" effect to cause the output signal to indicate expiration charge only after both thresholds are crossed.

Convention date, Sept. 27, 1933. [Class 40 (i)] [See also Group XL] Two independent variables, such as the co-ordinates of a point on a map, are transmitted as two sets of impulses the numbers of which are significant of the co-ordinates. At the receiver, the two sets of impulses are integrated to form two potential differences which are applied to the deflector plates of a cathode-ray tube so that the position of the spot on the fluorescent screen gives a reading of the two variables. The two sets of impulses may be transmitted as modulations, at two different frequencies, of a carrier wave, and after amplification de-modulation and separation at the receiver, the two sets of impulses are applied over transformers E1, E2 to two integrating devices the circuits of which are substantially as described in Specification 437,539. The integrated impulses appear as potential differences across condensers K1, K2 respectively and these potentials are applied to the plates P1, P2 of the cathode ray tube. The condensers K1, K2 are discharged by operating switches F1, F2.
