Abstract: The invention comprises thionophosphoric ester derivatives of the formula (RO)2P(S).SO.P(S)(OR)2 wherein R is an alkyl radical, preferably containing up to 6 carbon atoms.  They may be obtained by reacting a dialkylaminosulphinic acid chloride with a dialkyl-thiophosphite in an inert organic solvent, e.g. a hydrocarbon such as benzene, toluene, or ligroin, or by oxidizing a tetra-alkyl thionophosphoric acid disulphide of the formula (RO)2P(S)S.S.P(S)(OR)2, preferably with hydrogen peroxide in a weakly acid medium.  The reaction with hydrogen peroxide is preferably carried out in an inert organic solvent and at a temperature of 40 DEG  to 70 DEG  C.  Glacial acetic acid is a particularly suitable solvent but a liquid hydrocarbon may also be used as solvent if the reaction is carried out in the presence of a small amount of sulphuric acid.  Examples are given for the production of compounds of the above formula in which each R is ethyl, methyl, n-propyl, and iso-propyl, respectively, the compound in which each R is ethyl being obtained by oxidation of the corresponding disulphide by means of 37.5% hydrogen peroxide in the presence of glacial acetic acid at 40 DEG  C. and the other compounds being obtained by reacting dimethylamino-sulphinic acid chloride with the appropriate dialkyl thiophosphite in the presence of benzene.  An example is also given in which the compound in which each R is ethyl is obtained by the latter method and it is stated that compounds in which each R stands for n-butyl, iso-butyl, sec.-butyl and tert.-butyl may also be obtained from the corresponding dibutyl thiophosphites and dimethylaminosulphinic acid chloride.  In the example given for the production of the compound in which each R is isopropyl some tetraisopropyl thiono-phosphoric acid disulphide is obtained as a by-product.  The sulphoxide products are stated to be useful as insecticides (see Group VI).ALSO:An insecticidal composition comprises a solid or liquid carrier or diluent and one or more thionophosphoric acid esters of the formula <FORM:0822476/VI/1> wherein R is an alkyl radical, preferably containing up to 6 carbon atoms.

Title: Improvements in magnetic recording apparatus
IPC: G11B5/004
Filed: 1956-12-20
Abstract: 842,049. Magnetic recording and reproducing apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 20, 1956 [Dec. 23, 1955], No. 38808/56. Class 40 (2). A magnetic recording - apparatus includes a primary transducer associated with a datarecord path on one carrier and a plurality of secondary transducers associated with and spaced along a control path on another carrier, said secondary transducers being responsive to a single indicium on the control-path to selectively control operation of the secondary transducer whereby separate sections of the data record are recorded or reproduced. The embodiment shows a control disc D1 coupled to a data-record disc D2 by a shaft SH. Each of the discs are provided with magnetic peripheries, the control disc D1 having a single pulse signal REF thereon, and the disc D2 having a data track on five separate sectors which are required to be recorded or reproduced selectively. For this purpose five equally spaced separate transducers T1, T2, T3, T4 and T5 are arranged around the periphery of the control disc D1, while a single transducer T6 engages the datarecord D2 and is coupled to a utilization circuit via contacts operated by a relay RL4. According to the setting of switches A, B and C the pulse signal REF renders the said contacts of relay RL4 closed during the passage of the desired sector past transducer T6. It may be seen from the Figure that the point REF reaches transducer T1 as the beginning of sector RC1 reaches transducer T6. Similarly, T2 relates to the beginning of RC2, and so on. If the switches A, B and C are as shown in the Figure, the pulse in transducer T1, which is connected to the input of valve V1, which becomes conductive so that a positive pulse is delivered by valves V6, V7 and V8 to relay RL5 which closes to normally open contacts and, provided switch SP is closed, closes the contacts of relay RL4. When the pulse signal REF passes the transducer T2, which is connected to valve V2, the amplified pulse passes from valves V9, V10, V11 and actuates relay RL6 and breaks the contacts acting as a holding circuit for relay RL4 and disconnects the circuit of transducer T6. In a similar manner closing switch A renders the transducer T6 effective on sector RC2, closing switch B renders sector RC3 effective, closing switches A and B together renders sector RC4 effective, and switch C renders RC5 effective. Specification 819,789 is referred to.

Title: Improvements in or relating to counting devices
Inventor: STEDHAM MICHAEL EDGAR COLERIDG
IPC: B61L1/16
Filed: 1962-10-13
Abstract: 984,174. Counting apparatus. WESTERN COUNTIES BRICK CO. Ltd. Nov. 29, 1963 [Oct. 13, 1962], No. 38843/62. Heading G4D. Apparatus for counting objects moved through a counting station comprises a detector device having an input element to which the weight of each object to be counted is applied designed so that both the weight and speed of application of the weight must be within predetermined limits. The apparatus described is for counting barrowloads of bricks which are wheeled over a bridge 10 having a hinged platform 19 Fig. 1 supported at the free end on springs 23. The object is to prevent the counter being operated falsely by workmen jumping on the platform. The bridge has a further pivoted platform 20 supported on springs 28, acting as a preliminary detector. Platform 20 has a switch MS1 and platform 19 has two switches MS2, MS3 arranged to close sequentially as the platform is depressed. The switches are connected in a circuit so that a count is registered only if the platform 20 is depressed first and, after a suitable period, platform 19 is depressed at a rate such that switches MS2 and MS3 close with a certain interval (e.g. a tenth of a second) between them. A workman jumping on the platform operates the switches almost simultaneously. In the circuit Fig. 3, switch contacts a 1 , b 1  and c 1  belong to switch MS1, contacts a 2 -c 2  to MS2 and a 3 -c 3  to MS3. In normal use the barrow first passes over platform 20 closing contacts a 1  b 1  and operating relay A/1 which holds for about 3 seconds, e.g. due to capacitor C3. After the barrow leaves platform 20 the contacts b 1 , c 1  reclose connecting the supply voltage through relay contacts A1 (now closed) to relay B/1 which does not operate as it is short circuit by contacts a 2 , b 2 . The barrow then comes on to platform 19 closing first switch MS2 so that contacts a 2 , b 2  open and relay B/1 operates after a delay period during which its shunt capacitor charges to a predetermined voltage level. Further movement of the barrow depresses the platform 19 so that switch MS3 operates transferring the supply contact b from contact c 3  to contact a 3  which is connected via relay contact B1 (now closed) to the relay C/2. When relay contact C1 closes, the counter 30 operates and contact C2 operates an audible indication. If switch MS3 had been operated very quickly after switch MS2, relay B/1 would not have operated so that contacts B1 would be open preventing operation of relay C/2. Transfer of contact b 3 from c 3  to a 3  prevents the relay B/1 being operated after switch MS3. The relay C/2 remains operated, due to capacitor C5 for about one second so that it would not be practicable to count a barrow twice by moving it backwards off platform 19 and back on to the platform all within the space of the 3 seconds set by relay A/1.
