Title: Improvements in or relating to insecticides
Filed: 1924-08-18
Abstract: 245,179. Jackson, W. J. Mellersh-, (California Spray-Chemical Co.). Aug. 18, 1924. Insecticides for spraying plants consists essentially of viscous or solid non-volatile petroleum products purified to such a degree as to be free from ingredients harmful to plants and mixed with a volatile diluent or spreading oil such as kerosene. The mixture, containing preferably one part of viscous oil to two parts of kerosene, is formed into a concentrated emulsion with water and an emulsifying agent such as dried sulphitepulp waste liquor or dextrin, and is further diluted for use. Fungicides or insecticides such as arsenate of lead may be added to the emulsions. The viscous oil may be prepared from crude petroleum by removing the volatile portions by steam and fire distillation, separating a white oil stock of the desired viscosity, and purifying it by sulphonation, neutralization, steam distillation, and filtration; some or all of these steps being repeated until sufficiently pure oil, the physical and chemical properties of which are stated in the Specification, is obtained. Alternatively sufficiently pure commercial oils such as those known as Wyrol, Oxonite Crystal Oil, Nujol, and Marcol may be used. The volatile diluent need not be so highly purified, but a high grade kerosene such as that sold as Eocene is preferable. The prior use of emulsions of mineral, animal, or vegetable oils is referred to.

Abstract: 1534045 Automatic control of fuel supply to IC engines BENDIX CORP 12 May 1976 [23 June 1975] 19584/76 Heading G3N A fuel control system for an I. C. engine is responsive to sensed temperatures below a predetermined level and to loads above a predetermined level to give increased fuel delivery during a warm-up phase of the engine. In the arrangement shown in Fig. 5 the computing circuit 10 is supplied with signals from temperature sensor 14 and manifold pressure sensor 16 to provide control of the duration of fuel injected. Additionally a circuit 18 is provided which determines when the engine is required to deliver a high load during the warm-up phase and provides a signal to computer 10 to increase the injection duration to enrich the fuel supply. In the embodiment shown in Fig. 8 and described in detail with reference to a circuit, Fig. 9 (not shown), the temperature sensor 14 supplies a bias circuit 36 which ensures that comparator 40 provides a signal to give a level of signal to source 46 which gives a warm-up enrichment signal to the pulse generating circuit. The other input of comparator 40 receives a sawtooth signal if the sensed load is above a threshold set in circuit 34 and then this sawtooth wave is sampled by the temperature signal to provide a combined enrichment dependent on load and temperature.

Filed: 1948-07-22
Abstract: 668,370. Two-way transmission. COMPAGNIE INDUSTRIELLE DES TELEPHONES. July 22, 1948 [Oct. 28, 1947], No. 19641/48. Class 40 (iv). A signalling current amplifier arrangement comprises amplifiers 1 and 2, one for each direction of transmission, echo suppressors 3 and 4, and variable attenuators polarized so that the signalling currents are not applied to the input of the amplifier in the opposite direction before it is effectively blocked. Signalling currents at the terminals 10, Fig. 5, after amplification in valve 11, are applied to a rectifier network 13 and to a transformer 21. The former provides a negative blocking bias on the grid of the valve 12 and the latter feeds the attenuator network 5 which offers a high impedance until the output reaches a predetermined level corresponding with the effective blocking of the valve 12. A system which employs the normal speech amplifying valve for the amplification of signal currents is described with reference to Fig. 6 (not shown), and alternative dispositions of the rectifier arrangements 3, 4, 5 and 6, are contained in Figs. 2-4 (not shown).

Abstract: 780,137. Axial-flow compressors. GENERAL MOTORS CORPORATION. July 7,1955, No. 19661/55. Class 110 (1). In a multi-stage axial-flow compressor, the radially inner end of each row of stator blades carries at least one sealing ring made of aluminium, or an alloy containing at least 85 per cent aluminium, so that rubbing contact between the rotor rim and the sealing ring will wear and shape the latter. Sealing rings 21 are supported from stator blades 13, as by being pinched between flanged rings 17, 19 which are fixed to the inner ends of the stator blades 13 by upsetting tongs 20 extending from the blades through the rings 17, 19. The rings 21, which may be of conical form as shown so as to deform easily, are of soft metal such as aluminium or an alloy containing at least 85 per cent aluminium so that rubbing contact with the alloy steel rotor flanges 7 wears away the rings 21 to a minimum clearance. Peripheral ridges 23 further assist in reducing air leakage. The flanges 7 may be replaced by spacer rings not integral with the rotor discs 5.

Filed: 1961-06-01
Abstract: 970, 059. Gas sampling. SECRETARY OF STATE FOR THE WAR DEPARTMENT. Aug. 29, 1962 [June 1, 1961], No. 19784/61. Heading G1B. Gas-sampling apparatus comprises a sealed container e.g. a tube having a receptacle for a pool of liquid containing a contaminant sensitive reagent or reagents and having a fine jet 1 which is provided with a breakable seal and which projects into the container, the jet being so positioned and directed that when the seal is broken and liquid is present in the receptacle a fine stream of gas from outside can issue from the jet and intermix the gas and the liquid enabling any contaminant in the gas to interact with the liquid. The seal on the jet 1 may be broken by use of a wire loop 3 on a thin metal wire 2. The loop has a leg to hold it in position to break the seal. Contaminant sensitive reagents may be stored in breakable phials 4, 5 and a flexible bulb 7 is conveniently stored in one end of the tube as shown. In use the bulb 7 is removed and the tube broken at the point 6. The top of the tube is detached so that the loop 3 breaks the seal on the jet 1. The phials 4, 5 are broken to form a pool of liquid in the receptacle at the base of the tube and the bulb 7 is replaced. By squeezing and releasing the bulb 7 air or gas is drawn in through the jet 1 to swirl up the pool of liquid. The bulb 7 may be fitted with a non-return valve so that air or gas is only drawn in through but is not expelled from the jet 1, and the tube may be stoppered instead of being sealed at its top end. One of the reagents may be present as a dry film or deposit on the inside walls at the base of the tube and in particular the apparatus may be used to detect certain insecticides which inhibit cholinesterase, the cholinesterase being present as a dry film, a buffer solution in which it is soluble being provided in the phial 5. After sampling a chromogenic substrate is added from the phial 4 whereupon a colour will be developed if the enzyme has not been inhibited.
