Title: Production of carbinols
IPC: C07D213/30
Filed: 1966-06-01
Abstract: 1,144,474. Cyclopentyl and cyclopentenyl carbinols. SYNTEX CORP. 1 June, 1966 [4 June, 1965], No. 24384/66. Heading C2C. Cyclopentyl and cyclopentenyl carbinols are prepared by a two-stage process comprising (1) reacting a cyclopentadienyl Grignard reagent (or an alkyl- or cycloalkyl-substitution product thereof containing up to 8 carbon atoms in the alkyl or cycloalkyl group) with an aldehyde or ketone, and (2) hydrogenating the product (preferably catalytically) so as to reduce one or both of the double bonds of the cyclopentadienyl group. The process yields secondary alcohols when aldehydes are used for reaction with the Grignard reagent, but tertiary alcohols are obtained when ketones are used. Examples are given in which cyclopentadienyl magnesium chloride or bromide yields (1) ethylcyclopentyl carbinol by reaction with propionaldehyde, (2) cyclopentylphenyl carbinol by reaction with benzaldehyde, (3) 2-pyridylcyclopentyl carbinol by reaction with pyridine-2-aldehyde, (4) dimethylcyclopentyl carbinol by reaction with acetone, (5) ethylcyclopentylphenyl carbinol by reaction with propiophenone, (6) 1-cyclopentylcyclohexanol by reaction with cyclohexanone and (7) methyl cyclopentylphenyl glycolate and methyl cyclopentenylphenyl glycolate of the formulµ by reaction with methyl phenylglyoxalate. An example is given also in which methylcyclopentadienyl magnesium bromide and propionaldehyde yield ethyl-(methylcyclopentyl)-carbinol. Cyclopentadienyl magnesium chloride or bromide, used in most of the examples, is obtainable by reaction of ethyl magnesium chloride or bromide with cyclopentadiene.

Title: Improved electric water heating and hot water control apparatus
IPC: H05B1/02
Filed: 1956-08-10
Abstract: 825,013. Electric water heaters. RELF, V. K. Aug. 10, 1956 [Sept. 14, 1955], No. 24486/56. Class 39(3) [Also in Group XIII] Water heating apparatus comprises an electrically heated tank in which the water is held at a temperature above atmospheric boiling point under sufficient pressure to prevent actual boiling, the filling and temperature of the tank being controlled by a pressure or thermostatic control electrically connected both to the heating element and a solenoid inlet valve. As shown, a thermally insulated tank 1. has a. heating element 10 and a water supply connection 4 leading into the steam head of the tank 1 at point 7 via a solenoid valve 6, a restricting valve 5 also being fitted if the supply is of high pressure. Both the valve 6 and the element 10 are electrically connected to a pressure or thermostatic control switch 11. A float switch 12 operated by a float 14 and float arm 13 is electrically connected in series with the control 11 and the valve 6. A pressure release valve 15 with a two way air bleed valve 16, and a hot water outlet valve 9 are also provided. On heating, air escapes through the bleed valve 16, which then closes until the steam pressure reaches, for example 6 lbs. per sq. inch, at which pressure the control 11 is set to switch off the element 10 and open the solenoid valve 6, thus allowing cold water to enter and cool the tank contents and lower the pressure to, or example, 5 lbs. per sq. inch. At this point, the control 11 is set to close the valve 6 and re-energize the circuit. This heating and filling cycle continues until the water reaches a predetermined level, set by the float 14, when the float switch 12 operates to break the circuit to valve 6, leaving the control 11 to maintain the required temperature and pressure. On opening valve 9 hot water emerges under pressure via a pipe 8, and the float 14 drops to reverse the switch 12, thus allowing the filling and heating cycle to re-commence.

Title: A Supervisory System including a Measuring Bridge
IPC: G01N27/16
Filed: 1966-06-03
Abstract: 1,155,481. Measuring bridge circuits; methanometers. CHARBONNAGES DE FRANCE. June 3, 1966 [June 4, 1965], No.24916/66. Headings G1N and G1U. [Also in Division H3] A measuring bridge incorporating an impedance controlled by a parameter to be supervised is energized intermittently from a D.C. supply, and the variation in the output signal from the bridge when the supply is interrupted is transformer coupled to a tripping device which will initiate a tripping action for operating an alarm (or protection device) for all values of the parameter above a given threshold. The tripping device is unresponsive to any output signal occurring during a time immediately following connection of the bridge, so that initial reverse voltage spikes do not operate the alarm. In a bridge of the type containing a hot filament used in determining the content of methane in an atmosphere by catalytic combustion, the output increases in one direction as the methane content increases and then, above a certain content, sharply inverts to provide an output of the opposite polarity. To use the bridge to detect methane contents above a certain (low) level, outputs in the one direction above a certain threshold and all outputs in the other direction must operate an alarm. The bridge 1 containing the filament 13 and forming part of a supervisory fire damp meter is pulsed periodically by a D.C. supply Va switched on by a system 2 incorporating a multi-vibrator (T1, T2, Fig. 5) whose output is amplified and passed via one of a set of capacitors (C1 . . . . C N ) to a further capacitor (C4) which charges over a number of cycles, until a trigger circuit (T 5 , T 6 ) is operated. The further capacitor then discharges (via a transistor T4) to pulse on a transistor (T7) in the bridge circuit supply. The bridge is thus energized by way of a regulating circuit 3 (T8) for the period set by the trigger circuit. Thus the bridge is interrogated periodically at times determined by the chosen capacitor (C1 . . . . C N ). The change in output from the bridge at the end of an interrogation is fed via a transformer 4 to a trigger circuit 5 D  (T9, T11), which triggers if the signal is above a positive threshold set from a potentiometer 5 ID  (P1), and via an inverter (T13) to a trigger circuit 5 I  (T10, T11), which triggers if the signal is negative. The trigger circuit is prevented from operating for a time period after the bridge supply is switched on by the arrangement 52 (C5-R6-D4), which provides a negative voltage (to T11 base) for a time less than that for which the bridge is switched on. When the trigger circuit operates, a relay 7 (Re) is energized.

Title: Improvements in or relating to tariff recording equipment for telecommunication exchange systems
IPC: H04M15/38
Filed: 1938-08-29
Abstract: 520,681. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (Vriendt, C. de, and Kozma, L.). Aug. 29, 1938, No. 25290. [Class 40 (iv)] In a system in which particulars of calls are automatically recorded for metering purposes, certain lines are provided with means for enabling calls made on behalf of the telephone administration to be identified in the records. In the system described, the subscriber identifying equipment, which is of the type described in Specification 484,568, sends a preliminary digit 1 before normal calls and 11 before administration calls. The responding apparatus is designed to absorb the first impulse it receives and accordingly a dash is printed before the substation number in normal calls and a zero in special calls. Circuit operations-first system, Fig. 1. Special lines are provided with the additional line equipment Di, H, St &c. If a special call is to be made, relay Di is unbalanced by means of key K and energizes- H which locks up and breaks the metallic connection between the finder 4th wire and the terminal IL and connects relay St to the latter. In response to an A.C. signal from the recording equipment, group and line identifying switches are operated and in due course a circuit is made for the direct current double test relay Dt via wipers IF, CF, RI. Dt pulls up if there are no other switches connected to the test circuit, as described in Specification 507,192, and energizes Dh whereupon Lt is operated and Dt falls sluggishly. Lt connects up Ma, Ch in series in place of Dt. If the call is an ordinary one only Ch pulls up. If, however, the call is a special one the circuit for Dt and for Ma, Ch is over relay St instead of over finders 1LF, 2LF. St pulls up sluggishly in the circuit over Ma, Ch and shunts its high resistance winding and Ma then pulls up as well as Ch and removes the marking from bank scm1 which normally causes the sending switch. to send a preliminary digit 1. In consequence the stop relay Df is not energized until the sending switch has made a complete rotation and 11 impulses have been sent whereupon it pulls up over a contact of Us which it energized in position 9. Modified system, Fig. 2, for identification marking over the third wire. The arrangements are generally similar but in this case the relay H interrupts the D.C. connection over the third wire and does not provide a local connection to battery, a relay being provided in the identification circuit to test for this condition.
