Title: A process for the preparation of condensation products of ketones and polythioformaldehydes
IPC: C08G18/64
Filed: 1964-11-11
Abstract: Polythioformaldehyde/ketone condensation products are prepared by mixing the ketone with a polythioformaldehyde and a catalytic amount of an acid and reacting the mixture of -20 DEG  to 100 DEG  C. until the polymer is formed.  The polythioformaldehyde has the formula HS(CH2S)nH wherein n is preferably 2 to 7 or more, preferably 3 or 4. Suitable ketones are acetone, ethylmethylketone, diethylketone, methylisobutylketone, hexanones, heptanones, octanones, benzophenone, acetophenone, acetonylacetone, acetophenoneacetone, acetylacetone, fluorenone, phenylacetophenones, cyclopentanone, cyclohexanone and methylcyclohexanone. Suitable acid catalysts are hydrochloric, phosphoric or sulphuric acids, alone or in admixture with zinc chloride.  If desired the reaction may be carried out in the presence of a solvent such as benzene, ethylbenzene, toluene or xylene from which the product may be separated by distillation or the addition of a non-solvent such as methanol.

Title: Improvements in and relating to electrical protective relay circuits
Inventor: PADDISON ERIC
IPC: H02H3/40
Filed: 1966-10-14
Abstract: 1,131,666. Protective systems. ENGLISH ELECTRIC CO. Ltd. 12 Oct., 1967 [14 Oct., 1966], No. 46052/66. Heading H2K. In a protective arrangement having a composite operating characteristic provided by a plurality of measuring or relay units with different operating characteristics, incorrect operation due to a race between the units is prevented by a circuit having switching devices, e.g. transistors TR1, TR2, connected to the units and operable in response to signals received from all the units within a predetermined timed period to energize a protective means, e.g. a trip coil. This period is determined by a timer including a capacitor C1 which commences to charge when either transistor TR1, TR2 conducts. If the remaining transistor conducts before the capacitor C1 is charged then the trip coil is energized through transistors TR1, TR2 and TR7. If the capacitor is charged before the other transistor TR1, TR2 conducts, then transistors TR4, TR5 and TR6 become conducting and render the transistor TR7 non-conducting to prevent energization of the trip coil. Then if the remaining transistor TR1 or TR2 conducts a reset coil is energized through the transistors TR1, TR2 and effects the resetting of the measuring units and interruption of the signals to the transistors TR1, TR2. The reset coil is then de-energized. As shown the measuring units may be a mho unit and a reactance unit, in which case additional timing devices are controlled by the mho unit and permit three zone protection to be obtained. Reference is made to the use of more than two measuring units and to units providing ohm, impedance, directional impedance and directional overcurrent characteristics. Operation of the circuit under various conditions, including the manner in which the resetting action prevents incorrect operation, is described in the Specification.

Abstract: 1417770 Sheet processing apparatus E O SPRADLIN 4 Oct 1973 [4 Oct 1972] 46387/73 Heading G4M Prior art.-Records, e.g. indicating petrol sales made using credit cards are produced by imprinting a credit card number on a sales receipt carrying sales data. A plurality of such sales are entered on a sheet which along with the receipts are sent to a central station. The receipts are machine read and sprayed with a bar code. The bar code is used to sort the receipt into groups. The data from receipts is recorded on tape and the data is sorted and a customer statement is printed. The receipts are sorted and collated with the statements and both are microfilmed. The statement and receipts are sent to the customer (Figs. 1-5, not shown). Alternatively the micro film may be used to produce a copy of the statement and receipts. Present embodiment.-Credit transactions are recorded using a marking machine 40 on different lines of a special sheet. The sheet is exposed between slots 50, 52 and when roller 64 is moved across the machine the sheet receives an imprint from data wheels 42 which indicate the transaction and an imprint from the customers credit card placed in location 46. The customer also places his signature in a space on the line. A receipt for the customer is also produced. The sheets which also carry an identifying number are sent to a central processing location where either a micro-film of the sheet or the sheet itself is processed. The sheet is machine read and the data stored on discs. Any unread data is displayed on two cathode-ray tubes and data is keyed in by two operators. The keyed data must match before it is recorded. When all data is read each sheet is totalled and the dealer is billed. The data is then sorted into individual accounts and a micro-film of the customer statement is produced from which a copy is prepared (Fig. 11, not shown). This carries the date of each transaction, dealer identification, the amount, the customer's signature and his account number. The amounts are added and the balance displayed.

Abstract: Partially collapsed expandable cellular synthetic polymers are prepared by heating a chlorostyrene polymer body containing a conventional volatile fluid foaming agent to a temperature sufficient to heat plastify the body and cause it to expand and form a plurality of individual cells therein, subsequently subjecting the expanded body to steam at a pressure of 5 to 100 pounds per square inch gauge (1.3 to 7.8 atmospheres) for a period of time sufficient to cause further expansion and thereafter cooling the body to a temperature below the temperature at which the body is in the heat softened condition and collapsing the body to at least 60% of the volume obtained with steam under pressure. The preferred thermoplastic resins are polymers of monochlorostyrenes such as o-chlorostyrene, di-chlorostyrenes and copolymers and terpolymers thereof as well as copolymers with vinyl compounds and acrylic acid derivatives.  The product may be in block or particulate form and expands very slowly under ambient atmospheric pressure and temperature.

Abstract: 1480937 Data transmission; two way simplex systems FUJITSU Ltd 30 Oct 1974 [12 Nov 1973] 47073/74 Heading H4P A two way time sharing simplex system has a master terminal S with clock pulse generator to synchronize outgoing signals, e.g. dipolar RZ, while inhibiting reception, and a slave terminal R with a circuit to extract clock pulses for return transmission of RZ signals. Master and slave terminals transmit one bit alternately. The receiver part of each terminal may be disabled while a bit is being transmitted. An NRZ data signal is applied to terminal 12 and local clock to terminal 13 which are passed to gates A1, A2 controlling transistors 15, 17 so that data input 0's and 1's cause oppositely directed currents through half windings W1 of a transformer T. Signals induced into coupled winding W3 are not forwarded to the receiver due to gate 19 being disabled through inverter 20. On reception of signals from W1 in winding W4, through gates A4, A5 these are applied to a flip-flop FF2 which produces an NRZ signal output on terminal 25. Through OR 26 via delay DL a recovered clock sequence is developed, which through inverter 31 clocks A4, A5, also enables gate A6 to pass receiver data signals through transistor TS3 and winding W5 back to receiving portion of the master station which is now not inhibited. Single data pulses pass alternately in each direction. In a modification (Fig. 4, not shown) threshold Zener diodes are inserted in transistor base circuits and in another modification (Fig. 5, not shown) a transformer at each end having single primary and secondary windings only is used. In Fig. 5, also at the slave station, parallel amplifiers (C1, C2 set at different voltage thresholds are used as a discriminator to feed gates A4, A5. Fig. 7 (also not shown) illustrates a timing pulse extraction circuit connected to the output of gate A3 and controlling a further gate (A3<SP>1</SP>) at the input of monostable multi-vibrator MM.
