Abstract: The invention comprises compounds of the formula <FORM:1092696/C2/1> where R is a C1- 12 alkyl or C3- 6 alkenyl radical each of which may be substituted by halogen or a C1- 4 alkoxy group, or a C5- 6 cycloalkyl or cycloalkenyl radical, or a phenyl or benzyl radical optionally substituted by halogen or a C1- 4 alkyl group, R1 is hydrogen or a C1- 4 alkyl radical and R2 and R3 are C1- 4 alkyl or C3- 4 alkenyl radicals, and the acid addition salts thereof.  The compounds may be prepared by (1) heating a pyrazole of the formula <FORM:1092696/C2/2> with a thio ether R-S-CH2-Z, where Z is a radical which is easily split off as an anion, e.g. Cl or Br, preferably in the presence of a solvent and an acid acceptor; or (2) by heating a pyrazole of the formula <FORM:1092696/C2/3> in which Z1 represents a radical which is easily split off as an anion, e.g. halogen, with a mercaptan, RSH, and a compound of the formula <FORM:1092696/C2/4> where Hal represent halogen, e.g. Cl or Br, preferably in the presence of an inert solvent and an acid-acceptor.  Compounds in which R is a haloalkyl radical may be prepared by halogenation of the corresponding hydroxyalkyl compounds with, e.g., thionyl chloride or phosphorus tribromide.  The compounds are converted to the salts by reaction with inorganic or organic acids, e.g. HCl, HBr, formic, acetic and oxalic acids.  The carbamates are used in pesticidal compositions (see Division A5).ALSO:Pesticidal compositions comprise compounds of the formula <FORM:1092696/A5-A6/1> where R is a C1-12 alkyl or C3-6 alkenyl radical each of which may be substituted by halogen or a C1-4 alkoxy group, or a C5-6 cycloalkyl or cycloalkenyl radical, or a phenyl or benzyl radical optionally substituted by halogen or a C1-4 alkyl group, R1 is hydrogen or a C1-4 alkyl radical and R2 and R3 are C1-4 alkyl or C3-4 alkenyl radicals, and the acid addition salts thereof combined with a carrier and/or dispersing agent.  The compositions which are used as insecticides, may take the form of dusts, sprinkling agents, granulates, wettable powders, pastes, emulsion solutions or aerosols and may include synergists and auxiliaries, e.g. succinic acid dibutyl ester, piperonyl peroxide, DDT active substance, olive oil, peanut oil and phosphoric acid esters, or other biocides, e.g. phosphoric acid esters, carbamic acid esters, halogenated hydrocarbons, DDT analogues, and pyrethrines. The compositions may also include additives to increase adhesion, resistance to light and rain, and vegetable, animal and mineral oils to improve adhesion and penetration, baits and attractants, e.g. sugar or honey, and, for fumigants, combustible substances, e.g. paper or sawdust, and a source of oxygen, e.g. potassium chlorate or nitrate.  Compositions for plant protection may contain fertilizers, e.g. ammonium sulphate, phosphates and nitrates, urea and ground vegetable products.

IPC: H04M3/36
Filed: 1956-04-07
Abstract: 805,946. Automatic - exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. March 8, 1957 [April 7, 1956], No. 10693/56. Class 40 (4). An arrangement for counting the rate at which overflow calls occur has two counting circuits which are connected alternately to sum the overflow calls in successive predetermined periods of time, one circuit counting calls while the other circuit is connected to an indicator to display the count for the preceding period. An earth pulse operating an overflow meter OM also operates a relay OF twice, once with its leading and once with its trailing edge. Capacitors C2 and C3 act as counters by accumulating charge over R7 each time OF operates. The indicator comprises a pair of triodes VA, VB, in adjacent arms of bridge with a voltmeter M calibrated in overflow calls per unit time in one diagonal. The grid of VA is connected alternately to C2 and C3 while the grid of VB is held at a fixed potential. Interchange of capacitors C2 and C3 is effected by relays AY, AZ under the control of earth pulses which appear on lead EP at half-minute intervals. The first earth pulse on EP energizes AY which holds up and energizes AZ when the pulse ceases. Before AZ pulls back capacitor C3 is discharged over R4. The next earth pulse is diverted over a contact of AZ to hold AZ energized for the duration of the pulse and to forcibly release AY over its lower winding. Before AZ falls back at the end of the pulse C2 is discharged over R4.

Title: Method of making uniformly thin sheets of ceramic material
IPC: B29C48/08
Filed: 1955-04-14
Abstract: 803,163. Moulding ceramic articles. ELECTRIC MACHINERY MFG. CO. April 14, 1955 [April 26, 1954], No. 10739/55. Class 87(2). A method of forming a material in a thin layer 35 from a liquid mix 36 containing comminuted solids, e.g., the titanates of barium, strontium or lead, and a thermoplastic resin, e.g., low molecular weight polyvinyl chloride (PVC), upon an impervious surface 10, comprises forming a body of the mix 36 and passing the surface 10 upwardly in a direction making an angle to the horizontal beneath and in contact with the mix whereby a film 35 of the mix adheres to the surface 10. The surface 10 is a movable endless metallic belt passing round two drums 11, 12 and having an inclined portion 18 leading to a horizontal supporting surface 16. A parting agent, e.g., mineral oil, is sprayed onto the belt 10 at 20 which passes between electric radiant heaters 24, 25 which raise the temperature of the belt 10 above the polymerization temperature of the PVC, e.g., to 400F. to 450F. The portion 18 of the belt 10 continues below a hopper 31, having side walls 40, to which the mix 36 is fed under control of a valve 34 to maintain a constant liquid level 37 in the hopper 31, a wiper 39 preventing leakage of liquid. The level 37 is kept below the level of the surface 16. The preheated belt 10 emerging from the mix 36 carries with it a viscous liquid layer 42 and the layer 35 which, passing over the surface 16, is heated by electric resistors 46, e.g., to 350F. to 375F., to complete polymerization of the PVC. A knife 51 separates the resulting ware 50 from the belt 10. The ware 50 is cut to size and baked to burn out the resin and plasticizer and to unite the ceramic particles to form a uniformly thin plate. The liquid mix may comprise, proportions by weight, 10 to 12 parts comminuted ceramic, 1 to 3 parts PVC and 1 to 3 parts plasticizer. The thickness of the layer 35 may be controlled by the degree of preheating of the belt 10. In a modification, the thickness is determined by an adjustable doctor blade on the lower lip of the forward wall 41 of the hopper 31, the preheaters 24, 25 being omitted.

Title: Fuel injection apparatus arranged to supply fuel to a combustion engine
IPC: F02M51/04
Filed: 1975-03-17
Abstract: 1499125 Fuel injection pumps; regulating IC engine fuel injection HOLEC NV 17 March 1975 [22 March 1974] 11080/75 Headings F1A and F1B An engine 31 is supplied with fuel by a fuel injection pump 66 having a pump delivery control piston 80 loaded by a spring 74 and responsive to inlet manifold pressure, the natural frequency of the mass spring system comprising the spring 74, the piston 80, and the parts 52, 26 connected thereto being substantially lower than the frequency of pressure variations in the inlet manifold 78 when the engine is idling. Movement of the piston 80 displaces the leaf spring 52 and the wedge 26, the latter acting as a variable stop for two couplings 20 each connected between opposed injection pump pistons 63 and a respective electrically operated armature. The wedge 26 may be slightly stepped, Figs. 1 and 7 (not shown) or the couplings made of slightly differing sizes so that for a given setting of the wedge the fuel delivered to the inner engine cylinders 3b, 3d is greater than to the outer cylinders 3a, 3c. Before the engine has warmed up a duct 86, 87 connected between the inlet manifold 78 and a chamber 85 containing the spring 74 is connected by a thermostatically controlled valve 89 to a duct 88 connected to atmosphere through a filter 58. This causes the pump to deliver excess fuel. After warm up the valve 89 closes so that manifold pressure alone is established in the chamber 85. The armatures are oscillated by electromagnets (2a, 2b, 2c, 2d) supplied with control pulses by an electronic circuit, the timing of the pulses being dependent on e.g. engine speed, temperature or torque. A switch 92 closed by the control piston 80 when the manifold pressure is excessively low prevents the supply of control pulses and a further switch (103) coupled to the starter switch (81) causes the electromagnets to be energized twice during starting (See Specification 1499126)
