Title: Thiophosphoric acid esters
IPC: C07F9/165
Filed: 1958-06-17
Abstract: The invention comprises methylene-bis-(thionothiol-phosphoric acid esters) of the general formula <FORM:0825477/IV (b)/1> wherein R1 and R2 are like or unlike C1-C4 alkyl radicals.  They may be obtained by reacting a methylene halide (e.g. chloride, bromide or iodide) with a salt, preferably an alkali metal or ammonium salt, of an appropriate O,O-dialkyl dithio phosphoric acid in aqueous solution at an elevated temperature.  Specified products are the bis-(O,O-dimethyl), bis-(O,O-diethyl), bis-(O,O-di-isopropyl) and bis-(O,O-di-n-propyl) esters.  If the reaction of methylene chloride, bromide or iodide with the alkali metal or ammonium salts is carried out in an organic solvent (e.g. an alcohol or ketone) instead of in aqueous solution, the yields are stated to be unsatisfactory.  The products have good insecticidal properties (see Group VI).ALSO:An insecticidal composition comprises a solid or liquid carrier or diluent and one or more methylene - bis - (thionothiolphosphoric acid esters) of the formula <FORM:0825477/VI/1> wherein R1 and R2 are C1-C4 alkyl radicals which may be the same or different (see Group IV (b)). An example is given to show the insecticidal effect of a solution prepared by mixing an ester of the above formula in which R1 and R2 are ethyl with dimethyl formamide and then adding a benzyl hydroxy diphenyl polyglycol ether containing about 10 to 15 glycol residues (as emulsifier) and diluting with water.

Title: Improvements in transportation vehicles
IPC: B61D45/00
Filed: 1933-07-08
Abstract: 402,020. Vehicle undercarriages. KELLETT, W. P., 4501, Delafield Avenue, Fieldston New York, U.S.A. July 8, 1933, No. 19432. [Classes 103 (vi) and 108 (ii).] In a transport vehicle of the kind in which the body or load receiving platform is cushioned for longitudinal movement relative to the undercarriage or chassis, e.g. as described in Specification 390,431, the longitudinal movements of the platform &c. in starting and stopping and due to the recoil of the cushioning springs are braked, preferably by the provision of interacting friction surfaces on the platform and undercarriage respectively. According to the construction shown the undercarriage comprises longitudinal sills each consisting of two channel members 2, 3, Fig. 5, space a small distance apart and connected at intervals by brackets 4, which carry supporting rollers 11 for the load platform and are provided on the top with friction surfaces 8. Fitted to the under side of the platform to coact with the rollers 11 and surfaces 8 are cam blocks 15 and adjacent friction surfaces 17. In the normal position of the platform the lowest points of the blocks 15 rest upon the rollers 11 and the friction surfaces 8, 17 are out of contact with each other. When any displacement of the platform occurs against the action of the spring buffers 20, Fig. 2, which are fitted under the platform as described in Specification 390,431, the platform gradually descends, and the friction braking elements come into operation. Rubber strips 18, 19 disposed beneath the blocks 15 and friction elements 17 ensure an even support of the platform on the rollers and that all the surfaces 8, 17 come into engagement, while at the same time they cause the braking effort to increase with the platform displacement. Since the springs 20 have ultimately to raise the platform in restoring it to its normal position, 'undue recoil jolts and hunting are prevented.

Abstract: 816,462. Packaging machines. NATIONAL DAIRY PRODUCTS CORPORATION. June 24, 1957 [July 11, 1956], No. 19779/57. Class 94(1). [Also in Group XXX] A machine for telescoping lids over box bodies comprises converging conveyers, one for the bodies and the other for the lids, the lids and bodies being led into partially telescoped relation by the conveyers and being finally telescoped by applied pressure. The described machine places lids 4 on cheese cartons 1. The filled cartons are supplied by a conveyer 10 from which they are transferred by known means 11 to a conveyer 12. The boxes are delayed by means 17, Fig. 2, beneath the conveyer 12 so that they are engaged by pins 13 on the conveyer for positive forward transmission. The lids 4 are supplied by a conveyer 9 above the conveyer 12 and are subjected to a frictionally feed by a belt 18. At the base of the conveyer 9, they are engaged on either side by fingers 21 which retain the lowermost lid until the leading edge of a carton enters it and drags it clear of the fingers beneath a spring loaded pressure plate 28. A finger 47 on a pivoted rod 42 catches against the rear margin of the moving lid to distend it as the pressure plate forces the lid onto the carton. In the event of failure of a lid to engage a carton properly, the pressure plate will yield upwards and may operate a switch to stop the machine.

Title: Improvements in angle modulation receivers
IPC: H03G3/28
Filed: 1946-07-04
Abstract: 618,462. Frequency and phase modulation. RADIO CORPORATION OF AMERICA. July 4, 1946, No. 19985. Convention date, July 4, 1945. [Class 40 (v)] A circuit for receiving frequency or phase modulated signals comprises a frequency multiplier, means for selecting a particular harmonic and applying this to a demodulator, the arrangement being such that if the signal is below a predetermined amplitude substantially no harmonics are produced and therefore no signal is applied to the demodulator. Fig. 1 shows part of a superheterodyne receiver for frequency or phase modulated waves, the intermediate frequency signals being applied via I.F. transformer 1, to a pentode amplifying valve 3. This valve has a sharp cut-off characteristic, and elements R<1> and C<1> provide a short time constant automatic grid bias circuit. The output from valve 3 is applied to a discriminator circuit comprising tuned circuits P and S and a double diode valve 14. The circuits P and S are tuned to the second harmonic of the intermediate frequency, and the width of their band-pass characteristic is twice that of the I.F. circuits, so that these circuits together with diodes 14 act, at the second harmonic frequency, as a demodulator circuit of known type. Owing to the automatic bias action of R<1>, C<1>, the second harmonic output is produced by valve 3 only if the amplitude of the input signal is large enough to extend partly into the cut-off region of this valve. It is shown that the second harmonic output of valve 3 is substantially constant for values of input signal exceeding the predetermined minimum. Automatic volume control voltage is supplied by resistor R<1>, and the circuit elements associated with the screen grid of valve 3 may be adjusted to provide the desired cut-off voltage or output characteristic. It is stated that the circuit avoids the need for amplitude limiting, or noise squelch circuits. Specifications 489,094 and 547,276 are referred to.
