Title: Improvements in or relating to a process for the distillation of alcohol
IPC: C07C29/74
Filed: 1935-12-05
Abstract: <PICT:0471667/IV/1> In the production of monohydric alcohols by hydrolysis of the liquor resulting from the absorption of the corresponding olefines in concentrated sulphuric acid, an acid absorption liquor is used in which the weight ratio of total acid to water is at least 2 to 3 working on an alcohol-free basis.  The ratios specified for particular alcohols are: ethyl alcohol about 3,5 to 1, isopropyl alcohol at least 3 to 2, secondary butyl and secondary amyl alcohols at least 1 to 1 and tertiary butyl and tertiary amyl alcohol at least 2 to 3.  In the batch method of working, the distillation is preferably below atmospheric, such as 0,1 atmosphere absolute; in continuous working, atmospheric pressure may also be used.  An acid absorption liquor from a storage tank A, diluted with water from a pipe line 2 to give a liquor of the specified strength is supplied to the mid part of a column B.  The liquor contacts with water-alcohol reflux from the upper part of the column and with uprising steam from the base of the column and supplied thereto from a heater C.  Hot acid liquor is removed at the base of the column and the concentrated alcohol vapours flow from the top of the column to a reflux condenser F from which they return to the top of the column for withdrawal at an upper plate 9.  Reference has been directed by the Comptroller to Specifications 17159/98, [Class 2], 161,591, [Class 2 (iii)], 403,654, 427,223, 428,792, and U.S.A.

Title: Improvements in and relating to controlling arrangements for refrigerating systems
IPC: F25B49/02
Filed: 1927-12-14
Abstract: 282,397. Fabrique d'Appareils Electriques F. Sauter Soc. Anon. Dec. 14, 1926, [Convention date]. Refrigerating, compression machines for; circulating brine through chamber.-In a plant comprising an electrically driven refrigerating machine 2, a brine reservoir 1, brine pump 3 and pipes 10, 10<1>, 10" conveying the cooled brine through several chambers I, II to be maintained at independent temperatures, valves 6<1>, 7' in the brine circulating systems (actuated by motors m, m<1> controlled by thermostats 6<11>, 7<11> in the chambers) are electrically connected with a motor m<11> operating a valve 5<1> in the cooling-water supply pipe 8, 9 of the refrigerating machine, in such manner that the valve 5<1> is open so long as any brine valve is open but closed when all the brine valves are closed. The cooling-water when running flows through a balanced tank 4 on the actuating-lever W of switches q for the circuits of the machine 2 and brine pump motors 3<1>, so that when the water valve is shut the machine and pump are stopped. The thermostats move contact arms Z, Z<1> to control the motors m, m<1>, which actuate the brine valves through cranks s and also move switches k, h, k<1>, h<1> to open the motor circuits after actuation of the valves and to prepare them for the next operation. The starting switch 11 of the motor m<11> for actuating the water valve 5 is controlled by an electric relay r, r<1> in a circuit including the switches h, h<1>. In a modification the brine pump motor is controlled from the brine valve circuits independently of the cooling-water circuit. The brine valves may be actuated manually and control the circuit for actuating the cooling- water valve. Specifications 171,380 and 244,538 are referred to.

Title: Improvements in or relating to weighing apparatus
IPC: H03M1/00
Filed: 1963-08-27
Abstract: 1,059,681. Electro-selective signalling. HOBART MANUFACTURING CO. Aug. 27, 1963 [Aug. 31, 1962], No. 33873/63. Heading G4H. [Also in Division G1] Relates to apparatus for sensing and signalling the cessation of motion of a weighbeam 25 (Fig. 2), thus indicating equilibrium, and which may be used with automatic computing scale systems employing a cyclic binary to digital read-out system to provide a computer with a load weight indication. Two or more photo-cells 40, 41 normally used for reading a coded chart are used as motion detectors. The cells 40, 41 scan a projected image of columns A and C (Fig. 3), respectively, of a chart 26 which is movable with the weighbeam. The chart may have only sufficient markings for motion detection purposes or have a complete matrix of cyclic binary markings in columns A to N (A to D only shown) consisting of transparent areas in an opaque sheet. The markings in column A never coincide with those in column C; thus only one cell can scan a border line of a mark at any instant when the other cell will scan an opaque area. The cells 40, 41 respectively control thyratrons 50, 51 (Fig. 4) which when conducting energize relays A and C, respectively. Operation.-The movement of the chart marks may be at a frequency greater than the response time of the cells and causes a blur to be seen by the cells sufficient to make the thyratrons fire. Relays A and C are thus energized, so opening contacts A-2, C-2 and closing A-1, C-1, thereby permitting charging of delay capacitors 70, 71 and the circuit remains in this condition until movement of the chart has ceased. At any given balance position one cell will scan the image of an opaque area while the other cell scans a border line. The resistance of the one cell will increase and its associated thyratron will be cut off. However, the delay capacitor 70 or 71 will prevent immediate release of the associated relay for a time sufficient to ensure that the one cell is sensing a steady state and that the weighbeam is not merely reversing its direction of travel. Release of relay A or C will immediately cancel the delay on the other relay, by breaking contacts C-1 or A-1, so that it may also release instantly if the scale indication is such that both relays are to be de-energized. The opening of relay A or C at equilibrium, initiates the operation of a computer through contacts A-2, C-2 and energizes a relay T which applies power to a remainder of the photo-cell read-out circuits. Relay T also operates a relay U which disconnects the photocell power so that the thyratrons 50, 51 are now independent of any new movement of the scale and the read-out is not affected. At equilibrium the thyratrons energize the appropriate relays A to N in accordance with the condition of their associated photo-cells, and the resultant coded information may be translated into a decimal weight signal by the contacts of the respective relays and fed to the computer.

Filed: 1967-07-25
Abstract: 1,186,192. Teleprinters. ING. C. OLIVETTI & C., S.p.A. 25 July, 1967 [25 July, 1966], No. 34004/67. Heading B6F. A combination type-selector mechanism for a start-stop teleprinter translates incoming code signals to enable the simultaneously setting of printing code members, e.g. vanes 63, to control type-selecting clutches 50 on a typecarriage: the printing code vanes 63 are actuated simultaneously (via parts 64, 109, 99, 97 universal bails 104, 105 link 106, levers 113, 110 and cam 117) after being selectively set by levers 67 and transfer members 66, predisposed by sensing members 36, 37 which are all lowered to be selectively set by code elements 14 themselves sequentially set according to the various units of a received combination under the control of an anhythmical cyclically operating mechanism upon receiving a start impulse. A continuously rotating shaft 49, fluted so that the clutches 50 on the typecarriage may be driven for every letter-space position of the carriage, drives via a two-to-one step-up drive 48, 47, 46, a shaft 7 and gear 6. A clutch 21 controls the drive to a cam mechanism 23 and gear 6 drives a gear 5, frictionally coupled to a main shaft 3 which makes one revolution upon receipt of a start signal. This operates a trip member 9 and releases an arm 8. Rotatably mounted on a sleeve 12 on the shaft 3, is the set of five code elements 14 which are set into one of two positions. After the last element 14 has been positioned and while a stop impulse is received, the cam mechanism 23 operates and displaces all the sensing members 36, 37 downwards. A further cam 96 causes operation of a mechanism to simultaneously effect the type-selector mechanism.

Filed: 1967-07-26
Abstract: 1,172,126. Gas turbine fuel systems. ROLLS-ROYCE Ltd. July 25, 1968 [July 26, 1967], No. 34224/67. Heading F1G. [Also in Division G3] In a gas turbine power plant of the kind having a control valve for supplying fuel to a burner of a combustion chamber, the valve being operated by a device responsive to the ratio of pressures derived from the fuel pressure between the valve and the burner and from the delivery pressure of a compressor of the plant, there is provided a temperature sensing and control means responsive to working fluid temperature downstream of the burner and effective, when the worldng fluid temperature deviates from a datum value, to control a vent to atmosphere for compressed air delivered by the compressor and thereby to alter the ratio to which the device is responsive and correspondingly to restore the working fluid temperature to the datum value. The fuel may be gaseous or liquid or any mixture thereof. The invention is applied to the fuel system described in Specification 1, 013,132, in which the fuel flow to the burner is controlled by a throttle valve 2, Fig. 1, actuated by a servo-piston 6 subject on an annular area to a constant oil pressure supplied by a pump 12 via a governor 36, and an opposing variable oil pressure in a chamber 13, the latter pressure being derived from the constant oil pressure via a half-ball valve 17 carried by an acceleration control arm 18, 19 which is acted on by an adjustable spring 25, a plunger 21 subject to the fuel pressure downstream of the valve 2, and a plunger 22 subject, via a fixed restrictor 83, to compressor delivery pressure. The compressor pressure applied to the plunger 22 can be modified by venting to atmosphere by means of a flow control device 50 controlled by an actuator 51 and by means of a compressor overspeed governor 52, as disclosed in Specification 1, 013,132, and also by means of an additional control means 200, Figs. 1 and 2. The temperature of the working fluid downstream of the burner, e.g., in a duct leading to the power turbine, is sensed by at least one thermocouple, the electrical output of which is composed in an electrical bridge with a potential difference representing the datum temperature, the positive or negative output from the bridge resulting from any deviation of the temperature of the working fluid from the datum temperature being applied to an amplifier which provides a two-phase A. C. output to a reversible electric motor 218 which rotates a cam 215 in the appropriate direction to vary the opening of a halfball valve 206 which controls the venting to atmosphere of the compressor pressure applied to the plunger 22. A relay connected to the amplifier shuts down the plant if the power turbine inlet temperature becomes excessive.

Abstract: 766,495. Mine roof supports. BECORITGRUBENAUSBAU GES. Nov. 26, 1954, No. :34343/54. Class 20(2)  In a mine-roof lagging having pivotally connected lagging irons 5a, 5b, the locking member 10 between the lagging irons is a yoke having inwardly hooked ribs 10a, 10b which are inclined to one another and which embrace a pair of outwardly hooked transversely extending ribs 9 one of which is on one lagging iron and the other of which is on the other lagging iron, the ribs 9 in the assembled position of the lagging irons being inclined towards one another so that as the locking member 10 is forced along the ribs 9, the lagging irons are locked together by wedge action. In the embodiment described the ribs 9 are formed on coupling elements 8 about which the lagging irons 5a, 5b are horizontally swingable on vertical pivots 7, the lower parts of the elements 8 being formed as a socket joint 11 by means of which the irons are pivotally connected. One half joint 11a on one of the elements 8 is forked and receives between the forks the other half joint 11b on the other element so that the half joint 11b can slidably rotate in the half joint 11a. The half joint 11b has rectangular projections 12 which are engageable in - circular holes 11c in the half joint 11a by passing the projections through segmentshaped recesses 13 in the half joint 11a only when the lagging irons are at an angular position relatively to one another of about 90 degrees, thereby preventing unintentional disengagement of the bars in the normal operating position. In a modification referred to, a pivot pin joint with a push through pin can be employed in place of the socket joint and such pin and the locking member can be connected together. The locking member can be arranged below the axis of the pivot if the ends of the lagging irons are connected together scissors-fashion.
