Title: Improvements in and connected with Internal Combustion Engines.
Inventor: KENT-NORRIS HENRY
IPC: F02B19/10
Filed: 1918-08-02
Abstract: 130,742. Norris, H. Kent-. Aug. 2, 1918. Cylinders receiving liquid fuel. - Heavy liquid fuel from a pump j is injected first through a nozzle g in a preliminary combustion chamber c and then through a main fuel-injection nozzle d in the head of the cylinder, the second injection being prolonged for maintaining combustion at constant pressure. The chamber c contains a hot-plate 7 which may be heated. at starting, by a lamp. During the early portion of the delivery stroke of the pump j, the fuel for the first injection escapes past a valve r carried by the stem of the needle valve q, and traverses a passage t leading to the injector g, the orifice of which is provided with a spring-controlled ball valve w. When the valve r is closed by the pressure of the fuel behind it, the main injection takes place through the orifice in the nozzle d. The needle valve q is held in its closed position by a spring y, the tension of which is adjustable. According to a modified construction, the beat valve is dispensed with, the passage t being cut off by the sliding action of the spindle of the needle valve. Instead of entering a separate chamber, the igniting-charge may be admitted to the main combustion chamber.

Abstract: 578,113. Electron multipliers ; thermionic valve circuits. McGEE, J. D., KLATZOW, L., and SPENCER, R. E. Aug. 8, 1940, No. 12713. [Classes 39 (i) and 40 (v)] A photo-electric cell 3 has a photo-electric cathode 4, a plate-like anode 5 facing the cathode and constructed so as to emit secondary electrons when impinged on by photo-electrons, and an annular collecting electrode 6 surrounding the space between the cathode and anode. The construction and arrangement of the electrodes are such that the current-voltage characteristic curves of the electrode 6 is convex towards the voltage axis with a small slope over the lower voltage ranges, and over the higher voltage 'range becomes concave towards the voltage axis. In the example described, the cathode is formed as a portion of a sphere which may be sensitized by using a compound of antimony as described in Specification 513,523. The electrode 6 may be a flat ring as shown, but is preferably a ring of arcuate section arranged with the concavity facing the cathode. In the operation of the cell for indicating variations in the light flux falling on the photo-electric cathode, the electrode 6 is connected to the grid of an amplifier 8 through a condenser 7. The electrode 6 and anode of the amplifier are connected to a source of positive potential through resistances RA and 9 and a biassing potential is applied to the grid of the amplifier through a leak resistance RG. The impedance RA and the voltages applied to the electrodes 5, 6 are so chosen that the load line intersects the characteristic curves of the electrode 6 at their curved portions, whereby the output voltage variation is not excessive over a wide range of light flux.

Title: Manufacture of an improved mixture for making pavement
IPC: E01C19/10
Filed: 1931-05-05
Abstract: A bituminous composition for road-making &c. comprises solid fragments such as mineral aggregate, a bituminous binder, and a flux confined within porous material coating the solid fragments, the flux being set free, to act on the bituminous binder, when the porous particles are crushed by pressure between the solid fragments. Examples of porous material are diatomaceous earth, chalk, various kinds of limestone, spongy iron, polishing slate, tripoli, coke, granulated blast furnace slag, and porous concrete. Examples of fluxes are soft bitumen, lubricating oils, benzine, paraffin oils, naphtha, tar, pitch, carbon bisulphide, and carbon tetrachloride. The porous material and flux may also be combined naturally, e.g. certain kinds of earth or rock impregnated by nature with lubricating oils, bitumen, &c.  The ingredients may be mixed in any order or manner which ensures that the flux is absorbed by the porous material.  In an example, dried stone material is mixed first with oil in a suitable mixer; powdered material containing porous particles is then added to absorb the oil, the stone thus becoming coated with a thin layer of porous material containing flux; molten, dissolved or emulsified bitumen is then added and the composition is ready for laying. Specification 161,671, [Class 22, Cements &c.], is referred to.

Title: A device for counting and discharging hairpins and similar bifurcated objects
IPC: G06M7/04
Filed: 1943-08-16
Abstract: 605,254. Counting-apparatus. ROWLEY, H. E. G. (Chain Store Products Corporation). Aug. 16, 1943, No. 13271. (Class 106 (i)] Apparatus for counting hairpins and the like in batches of a predetermined number comprises a feeler 45 against which the hairpins rest and which is released to allow the hairpins to move into a counting zone between the feeler 45 and a stop 53, the stop being subsequently lifted to permit the hairpins to discharge only if the counting zone is full. The feeler 45 is on a lever 44 pivoted at 43 to a rockable frame comprising side plates and end blocks 24, 25, the frame being pivoted to a fixed support by a spindle 21. A discharge lever 28 is connected to the frame by a pivot 27 having a flattened part 30, Fig. 3, engaged by a cam block 34 carried by a spring 31 fixed to the support. When the discharge lever 28 is turned clockwise, Fig. 4, the pivot pin, cam block and spring interact to swing the frame anticlockwise until it engages a fixed stop 38. The feeler 45 is thus removed from the path of the hairpins which then slide into the counting zone until they meet the stop 53 which is carried on a lever 51 pivoted to the rockable frame at 39. When the discharge lever 28 and rockable frame return to normal position, if the counting zone is filled with hairpins, the feeler 45 will engage the top of a pin, whereby the lever 44 will be rocked clockwise and through a screw 57 will rock the lever 51 to raise the stop 53 to release the batch of pins which then slide on to a receiving bar 5. The stop 53 is adjustable along a slot on the lever 51 to vary the number of pins in a batch.

Title: Negative resistance diode storage circuits
Inventor: PERRY GERALD HORACE
IPC: G11C11/38
Filed: 1961-04-13
Abstract: 984,222. Electronic data-storage apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 19, 1962 [April 13, 1961], No. 13289/61. Heading G4C. [Also in Division H3] An information storage circuit comprises a negative resistance diode in series with a resistance to form a two state circuit, means for interrogating the circuit with a pulse sufficiently small that the state of the circuit is not switched, and means responsive to the output of the diode for detecting whether it is in its low or high resistance state. As described with reference to Fig. 5, application of a negative pulse to input IT clears the store, setting both tunnel diodes D1, D2 to their low voltage state. Upon application of a small positive interrogation pulse to input IT, equal amplitude pulses are produced in the centre tapped winding of transformer T which cancel to produce no output at Vo. Simultaneous application of a positive input at IS1 a positive input at IT and a negative input at IS2 switches tunnel diode D1 to its high voltage state to store a "0", and a subsequent interrogation pulse produces unequal pulses in the two halves of the centre tapped winding of T, resulting in an output pulse at Vo. Conversely positive pulses at IT and IS2 and a negative pulse at IS1 result in D2 switching to store a "1" and a subsequent interrogation pulse produces at Vo a pulse of opposite polarity. A number of basic circuits may be combined to form a matrix store, Fig. 6 (not shown). Stores comprising a single diode are also described, Figs. 1, 2 (not shown) in which the interrogation is applied to the junction between the diode and the resistor.

Title: Resuscitator control means
IPC: A61M16/20
Filed: 1947-05-16
Abstract: 627,650. Respiratory appliances. E. J. MANUFACTURING CO. May 16, 1947, No. 13299. Convention date, May 20. 1946. [Class 81(ii)] [Also in Group XXIX] In a resuscitator of the pulmometric type the valve is secured to a snap action leaf spring which is actuated by a pressure responsive means. Gas is supplied to the resuscitator body through a tube C and passes through a venturi tube arrangement 20, 21. A snap action leaf spring 25, set between resilient supports 31, carries a valve member 23 which closes the central passage in its lower position and opens it when raised. The pressure responsive diaphragm 13 is connected by a stirrup member 27, passing around the central tube, to a second snap action spring 26 and the stirrup carries an adjustable abutment member, see Fig. 3 (not shown) which, in its upward movement bears against the under surface of the spring 25 and carries it upwards. With the parts in the positions shown, gas is supplied through the tube C and the tube 9b is connected to a face mask applied to the patient. The gas, being unable to pass through the central tube owing to the closed valve 23, passes through side apertures 20b to the interior of the housing and to tube 9b. As the pressure increases in the lungs, the diaphragm rises until, at a predetermined pressure, the spring 26 snaps over dead centre and the abutment carried by the stirrup lifts the spring 25, which also snaps over to its upper position and opens the valve. The venturi arrangement now acts as an ejector and the previously inhaled gas is withdrawn through the tube 9b and apertures 20b and passed out through a muffler H to the atmosphere. This continues until a predetermined rarefaction is produced in the unit, whereupon the diaphragm 13 forces the spring 26 back past its dead centre position and the centre of the diaphragm bears against the upper surface of the spring 25, so forcing this and the valve 23 back past dead centre to the closed position. This cycle is continuously repeated. Specification 595,658 is referred to.

Abstract: 699,773. Drying gases. BRITISH OXYGEN CO., Ltd., and WEBSTER, T. J. May 29, 1952 [June 5, 1951], No. 13302/51. Class 34 (i) In gas-drying-apparatus of the type in which the gas is passed downwardly through a bed of granular alumina or other granular adsorbent, regeneration is performed by passing a stream of heated gas introduced at the top of the drier downwardly through the adsorbent passing a second stream of heated gas upwardly through the adsorbent and withdrawingboth streams from the drier at a point intermediate its top and bottom the velocity of the second gas stream being insufficient to lift the adsorbent granules and its length of travel through the bed being sufficient to prevent passage of moisture through the drier. The regeneration gas is fed through inlet 13 to heater 14 and thence through pipes 15, 16, 17 controlled by valves 18, 19 to the upper ends of driers 2, 3 respectively, which driers operate alternately, and through pipes 20, 21, 22 controlled by valves 23, 24 to the lower ends of the driers. The gas is withdrawn through pipes 25, 26 controlled by valves 27, 28. Electric heating coils 29, 30 round the outer surfaces of the driers raise the shells to regeneration temperature and eliminate loss of heat from the gas to the shell.
