Title: Cardiac monitor apparatus
IPC: A61B5/308
Filed: 1962-03-23
Abstract: 1,005,885. Measuring electrically. CHEMETRON CORPORATION. March 23, 1962 [March 23,1961], No.11233/62. Heading G1N. [Also in Division A5]. Cardiac monitoring apparatus comprises an electrically conductive case for attachment to a part of the body to form one electrode and a monitoring circuit in the case and connected between the case and a terminal for a second electrode, the monitoring circuit including a power supply 19, an amplifier 20, 35, 50 and decoupling means for preventing load surges from affecting the power supply, said decoupling means comprising a capacitor 74 in parallel with the power supply. The circuit including a speaker 82 and/or an indicator lamp (not shown) is contained in the casing. The amplifier comprises three stages including transistors 21, 36, 51. The first stage includes high frequency attenuation means comprising a capacitor 30 and a resistor 26 in a negative feed-back circuit. A capacitor 33 in the amplifier input prevents D.C. leakage through the body affecting the transistor base of the first stage. A resistor-capacitor part 48, 49 decouples the battery from the first two amplifier stages. The output of the second stage is modified by an integrating capacitor 46 to extend the time base of the final signal. The amplifier output is supplied through a plug and socket connection 63 to either the indicator lamp or to an oscillator 65 which comprises a transistor 66 and is decoupled from the battery by a resistor capacitor pair 73, 74. The oscillator output is coupled to the circuit of the speaker through a transformer 75. The biasing of the transistor 66 is controlled by resistors 83, 84, 85 and a rheostat 86 which is adjusted to produce the required oscillation amplitude by a knob 17 on the casing. The knob also operates an on-off switch 78. A diode 91 diverts any rectified signal appearing on the base of the oscillator transistor.

Abstract: 699,561. Rivets. CARLTON TYRE SAVING CO., Ltd. Nov. 19, 1952 [May 6, 1952], No. 11367/52. Class 89 (i) A number of plugs for hollow rivets are connected together by flexible and easily broken links to facilitate handling. The plugs may be of polythene but a more brittle material could be employed. The plugs have rounded ends E, Fig. 2 followed by taper sections H, to facilitate entry into the rivets and they are driven in place by a hammer blow that also effects the severance of the plug from its connecting strip F which is weakened at H to facilitate severance. The strips form the runners of a multiple casting and communicate with a central transverse runner B supplied at A by injection moulding. In a modification the plugs are connected transversely also, the runners producing a grid formation and in a further form the runners connect with the plugs at points intermediate the ends thereof.

IPC: B05B12/12
Filed: 1963-03-26
Abstract: 1,038,212. Coating apparatus. AERASPRAY ASSOCIATED Ltd, & WITTON ELECTRONICS Ltd. June 24,1964 [March 26,1963], No. 11837/63. Heading B2B. Apparatus for spraying a sheet or plate of material includes a spray-gun mounted on a carriage which is adapted to receiprocate over the sheet or plate and carries at least one probe which is adapted to render the spray gun inoperative when the carriage passes beyond the edge of the sheet and to render the spray gun operative when the carriage again crosses the edge and the spray gun is located adjacent the surface to be sprayed. A carriage 12 which supports spray gun 10 and reciprocates transversely over the surface of a sheet 13 of steel carries two probes 16,17 each containing two Reed type relay contacts adapted to be closed by magnet 19 disposed beneath the plane of the sheet except when and where the steel sheet 13 intervenes. Operation of the spray-gun is controlled by a solenoid air valve 18 which is opened and closed in dependence upon the operation of the contacts in the probes 16,17. A plate 20 disposed on the carriage 12 cooperates with sensor devices 21, 22 to sense the direction in which the carriage is moving and to render the leading probe at any given moment effective for sensing the position of the edge of the sheet. After reversal of the direction of the carriage the previously trailing probe becomes and is rendered effective as the leading probe. An inhibitor plate 23 co-operates with magnetic inhibitors 24, 25 to ensure that chance activation of the spray gun does not occur when it is located outside the surface of the sheet. A similar spray gun 11 and carriage 14 with probes 16, 17 is located beneath the sheet 13 and is adapted to spray the under surface thereof. In an alternative embodiment (Fig. 2, not shown) each - probe contains a magnet and a Reed type contact held open thereby except when brought into proximity with the steel sheet. Ultrasonic devices may be used instead of magnetic, each probe then incorporating an ultrasonic transmitter and a contact adapted to be opened by ultrasonic vibrations reflected back from the sheet or plate of material. A single probe may be used for each spray gun the probe being mounted on a sliding arm adapted to change over to the leading side of the carriage at each reversal of direction.

Abstract: 560,459. Pressure gauges. PAULIN, J. G. Aug. 22, 1942, No. 11843. Convention date, Aug. 23, 1941. [Class 106 (ii)] [Also in Group XXTX] A pressure measuring contrivance for determining water levels comprises a back pressure vessel connected to a pressure gauge, a diaphragm arranged in the vessel and acted upon on one side by the pressure to be measured and on the other side by the back pressure and two independent valves located in the vessel to control automatically the back pressure in accordance with the alterations in pressure. The liquid, the depth of which is to be measured, passes through openings 19 into the casing and acts on the outer surface of the diaphragm 15. The threaded bolt 33, secured to the surface 31 and passing through nuts 34, 35, rises and lifts the right arm of lever 27 depressing spring-ballvalve 23 to admit compressed air from a pipe 6 to chamber 13 and hence to the interior of the diaphragm until balance is' restored when the valve 23 closes. The chamber 13 communicates with a pressure gauge by means of the pipe 3 and this gauge registers the depth of liquid. When the liquid level sinks, the valve 24 is opened and pressure fluid from chamber 13 is exhausted to the atmosphere via pipe 5 until balance is restored. The nuts 34, 35 may be adjusted to engage the perforated plate 37 at high and low limits to prevent damage due to sudden fluctuations.
