Title: Improvements in pistons for internal combustion engines
IPC: F16J1/16
Filed: 1931-06-08
Abstract: 375,975. Pistons. KRAFTFAHRZEUGBEDARF KOMMANDITGES SCHœTTLER & CO., 51, Chausseestrasse, Berlin. June 8, 1931, No. 16691. Convention date, June 21, 1930.

Title: Automatic graphing apparatus
IPC: G01N27/26
Filed: 1973-04-09
Abstract: 1471143 Integrating and recording apparatus JOYCE-LOEBL Ltd 9 April 1974 [9 April 1973] 16836/73 Heading G1J A recorder which plots a graph of a varying analogue input signal, e.g. from a photometric scanning apparatus 10, includes a calculating circuit 16 comprising an integrator which provides an output proportional to the time integral of the input signal, a trough detector 22 to detect minimum points in the input signal, and a control circuit 24 which interrupts the plotting operation in response to detection of each minimum point and causes a value indicative of the output of the calculating circuit 16 to be recorded, after which the plotting operation is continued. With the photometric scanning apparatus, the recorder plots a continuous trace of the scanner 28 output plus, at each trough in the plot, a vertical line 92 the height of which is proportional to the area 90 under the trace between that trough and the previous one.  The recorder pen is controlled by a servo drive 32, 34, 36 and the chart is driven by a motor 30. In the operation of the photometric scanning apparatus 10, the scanning mechanism 26 effects relative movement between the scanning head 28 and an electro-phoresis strip at constant speed in one direction, followed immediately by a reverse scan at the same speed, giving a variation of output voltage with time which is symmetrical about a centre portion BC, Fig.4. During the forward scan AB the pen and chart drives and a trough detector circuit 22 are kept inoperative by the control circuit 24, the scanner output voltage being fed to the integrating circuit 16, which was reset at the start of the scan. At point B, the integrator 16 output is sampled and stored by a circuit 40, the stored value being proportional to the total mass of material in the specimen band of the electro-phoresis strip. At C, the integrator 16 is reset, and a second sample and hold circuit 52 is caused to store the output of an analogue divider 38. The divider 38 output at any instant is proportional to the output of the integrator 16 divided by the value stored in the circuit 40, plus a constant offset voltage. The circuit 52 corrects for the offset voltage by storing said voltage, i.e. the divider 38 output when the integrator 16 output is zero. Also at C the pen and chart drives and the trough detector 22 are activated, the pen servo 34 receiving the scanner output voltage via a switch 14 so that the trace, CD is plotted. At D, the trough detector 22 stops the scanning mechanism 26 and the chart drive 30 and circuit 24 opens switch 14 and closes a switch 20 so that the pen servo receives a signal representing the area 90 as a percentage of the total area under the trace, and draws the line 92. Then the integrator 16 is reset, the chart drive and scanning mechanism restarted, switch 20 opened, and switch 14 closed, so that the next stage DE of the trace is plotted.

Title: Improvements in and relating to a system for heating a space such as an aircraft cabin subject to super-charging
IPC: B64D13/08
Filed: 1939-06-08
Abstract: 530,320. Heating aircraft. PRICE, N. C., and BOEING AIRCRAFT CO. June 8, 1939, No. 16845. [Classes 64 (ii) and 64 (iii)] Relates to means for heating aircraft cabins which are subject to wide variations of temperature and pressure conditions. A steam generator 1 in the exhaust pipe 9 is connected to a radiator 2 in the air intake 91 leading to the cabin, and condensate passes to a tank 30 from which it is returned by a pump 3 to the boiler. A sump 4, Fig. 3, is connected to the system, and water is expelled from it by heat derived from exhaust gas passing through the conduit 46. The rate of circulation of steam and therefore the rate of warming of the air in the conduit 91 is controlled by regulating the rate of the pump 3. When the system is not in use, all water drains to the sump 4, which is of sloping shape to resist damage by freezing. The boiler 1 is constructed as described in Specification 530,361. The radiator comprises tubes 23, Fig. 6, through which air passes, arranged within a shell 24 through which steam passes. Air initially within the closed system passes into the jacket 25 through an opening at its lowest point, and condensate is discharged through pipe 22. The air expands and refills the system when cold. The condenser is supported at its junctions with the conduit 91 by rubber sleeves to prevent vibration. The pump, Fig. 7, comprises a plunger 31 reciprocating in a cylinder 32, and having a stem 33 controlling an electric circuit for operating the valve 34 by means of a solenoid 36, which, when energized, is attracted by a fixed pole 38. The pump is driven by the pressure fluid used in the hydraulic remote control system of the aircraft, which is supplied and discharged through conduits 51, 52 respectively to and from the working cylinder 50. The rate of working of the pump is controlled by thermostatically adjusted valves in the cabin and in the duct 91. The solenoid circuit is controlled by the reciprocation of the bell crank lever 81, 82, coacting with the contact 84. The pump is started and stopped by a thermostat 8 in the cabin and thermostat 80 in the air duct 91, and a pressure limit switch 85 subject to the pressure in the tank 30 through which the fluid passes to the pump.

Title: Improvements in or relating to liquid flow systems
Inventor: MARTIN WILLIAM ALEXANDER ONSLO
IPC: F02C7/228
Filed: 1952-07-04
Abstract: 735,709. Gas turbine plant. ROLLS-ROYCE Ltd. June 24, 1953 [July 4, 1952], No. 16934  52. Class 110 (3) [Also in Group XXIX] A valve for compensating for the variation of head in a liquid fuel conduit due to acceleration of a body such as an aircraft in which the conduit is installed comprises a tubular valve member 22 slidable in a chamber whose axis is aligned with the acceleration to be compensated, an inlet 20 to the chamber controlled by the valve member, the mass of which is chosen in relation to the area of the inlet to provide a force under acceleration to oppose the head of fuel so as to restrict the flow from the inlet through passages 23 to the outlet 21c, a second inlet 24 to the chamber at right-angles to said axis, and lateral port means 25a in the valve member to co-operate with the second inlet upon movement of the valve member away from the seating surrounding the inlet 20. By using the valve member to oppose only a portion of the flow through the valve, that passing through the inlet 24 not exercising any axial force on the valve member, the mass of the valve member may be minimized as-compared with the arrangement in Specification 709,724 in which all the flow passes through the inlet at the end of the valve member. The embodiment shown is described applied to a liquid fuel manifold of a gas turbine engine. In one arrangement, for compensating for vertical acceleration, the connection between each burner and the manifold incorporates an acceleration compensating valve with its axis vertical, the mass of each valve member being chosen according to the height of the point at which the connection to the manifold is made. Alternatively, each valve may be so arranged that the axes along which the valve members slide intersect each other at the centre of the engine and each valve member is acted upon by a spring. In another embodiment a single valve is used in a fuel conduit connecting an engine with a fuel tank in an aircraft to compensate for variations of head due to longitudinal acceleration of the aircraft.

The pillar comprises a lower section 24 mounted on a base 20 and closed at its upper end by a plate 36 with a central aperture and a circular array of ports 40 closed by a valve member 46 mounted within the central aperture. A spindle 76 passes through the valve member and is secured at one end to the upper end plate 74 of the upper sections 54 whereby, when compressed air is fed into the upper section causing the same to rise, upon said upper section reaching a predetermined height the spindle lifts the valve member 46 to uncover the ports 40 and thereby prevent the upper section rising further. The upper and lower section having bearing sleeves 64 located therebetween to allow relative rotary motion therebetween. The lifting arm comprises a rear section 96 fixed to the pillar, and an intermediate section 102 movably received within one end of the rear section and mounting a pair of rollers 112, 130 which respectively engaged the upper and lower surfaces of the rear section. Bolts (120), (132), Fig. 5 (not shown), which secure the respective shafts 116, 124 for the rollers 112, 130, have heads which bear on the sides of the rear section to centralize the intermediate section within the rear section. A front section 104 of the boom is similarly mounted within the intermediate section by rollers 140, 150 and bolts (142), (148) Figs. 7, 8 (not shown), and mounts a loop 212 by which articles may be secured to the lifting arm. A pneumatic ram 106 is mounted parallel to the lifting arm and is connected between the rear section and the intermediate section to effect movement of the intermediate section relative to the rear section. A flat metal strip 160 secured at one end to the rear section, by a tensioning bolt 162, passes over an idler wheel 164 and is secured at its other end to the rear end of the front section by a bolt 166. A further metal strip 168 secured by a bolt 170 to the rear section passes over a roller 172 mounted on the rear of the intermediate section and is secured at its other end to the rear end of the front section. The strips ensure that movement of the intermediate section results in corresponding movement of the front section. A pair of valves 180, 182 respectively controlling the supply of air to the ram 106 and the upper section of the pillar are controlled by respective control rods 188, 190 coupled to a control lever 200 by a control box 192 mounted at the outer end of the intermediate section of the boom; whereby vertical movement of the lever results only in movement of the control rod 190 and hence vertical movement of the lifting arm and horizontal movement of the lever results only in movement of the control rod 188 and hence horizontal movement of the lifting arm. Rotation of the arm is effected by manual effect.
