Title: Improvements relating to forced circulation steam generators
IPC: F22B35/08
Filed: 1970-12-14
Abstract: 1,269,189. Forced circulation steam generators. SULZER BROS. Ltd. 14 Dec., 1970 [12 Dec., 1969], No. 59344/70. Heading F4A. A forced flow steam generator of the type having at least two evaporator tube systems traversed by parallel flows of working medium and each comprising a plurality of tube lengths arranged in parallel in respect of the flow of working medium and which cover a boiler wall over at least part of their length is operated with sliding pressure control. When close to critical pressure the output from each evaporator is split: a portion from each being supplied for recirculation to a point upstream of the evaporators and a portion passed to a common superheater means. At or above the critical pressure it is arranged that: a difference of at least 30 Kcal./kg. of working medium is produced between the enthalpy of the working medium leaving each evaporator; and that the evaporator producing medium of the higher enthalpy provides the major portion of superheater input, while that producing medium of lower enthalpy provides the major portion of the medium to be re-circulated. In one embodiment, both evaporators I and II are heated equally but one has its input restricted by valve 39 and will therefore produce working medium of higher enthalpy than the other. The evaporators feed steam/ water separators 21, 22; the water being recirculated at 15 and the steam being passed to superheater 28. Because of the enthalpy difference in the outputs of the evaporators, evaporator II will produce the most steam while evaporator I will produce the most water. In another embodiment, Fig. 5 (not shown), both evaporators are again heated equally but the difference in enthalpy is obtained by shielding one set of evaporator tubes from the boiler wall with reheat tubes. The separators may have their water compartments connected, giving a single water level, and there may be provision to condense saturated steam by spraying it with feed water between the discharge of the lowest enthalpy evaporator and the water level.

Abstract: 1287374 Telephone exchanges; transistor bi-stable and gating circuits INTERNATIONAL STANDARD ELECTRIC CORP 17 Dec 1970 [19 Dec 1969] 59932/70 Headings H3T and H4K [Also in Divisions G4-G6] The cross-point elements (Xjk) of a switching matrix comprise MOS field-effect transistors (Q<SP>1</SP>, Q<SP>11</SP>) of large geometry such that the gatesubstrate capacitance (Cgt) is sufficient to hold the cross-point operated during periods in which, due to switching of an auxiliary transistor (Q1), the cross-point operating potential from a bistable (Wjk) is disconnected. Each cross-point Xjk of the matrix shown in Fig. 3 has a corresponding controlling bi-stable Wjk in a stepping register RW. The register has sections RH comprising the bi-stables of each row of the matrix. To operate or release a cross-point the entire contents of the register RW are read out serially over outlet DO to a processor which feeds back into the register over inlet D1 a new pattern of data containing the modifications required. In order that cross-points of the matrix should not be disturbed by the changing states of the bistables as data is moved in and out of RW, a signal EN over inverter N2 cuts off all auxiliary cross-point transistors Q1 to isolate the crosspoint transistors Q<SP>1</SP>, Q<SP>11</SP>, which, if operated, stay held by gate-substrate capacitance Cgt. When the new pattern is established in RW the signal EN is removed and the cross-points are controlled by the bi-stables Wjk. Stepping register.-The presence of signal EN opens transistor Q0 to gate stepping pulses H to register RW, an inverter N1 producing complementary stepping pulses H. As shown in Fig. 5 each stage of the register RW, comprising a bi-stable Wjk has an input Cl<SP>1</SP> from a preceding stage and an output DO<SP>1</SP> to the next stage. If a "one" input is on Dl<SP>1</SP> a pulse H switches on transistor Q2, of an inverter Q2, R2, and this cuts off Q3 of an inverter Q3, R3. When pulse H gives way to its complement H, Q2, Q3 remain held by their gate-substrate capacitances C2, C3, while Q6 is opened to connect to output of Q3 to hold Q2 cut off. At this time, and while the register is not being stepped, Q7 is opened to gate the bi-stable state over inverter Q4, R4. The arrangements are produced as integrated circuits using MOS-Ph transistors.

Abstract: 601,427. Calculating-apparatus. FELT & TARRANT MANUFACTURING CO. July 23, 1943, No. 28162/45. Convention date, Aug. 8, 1942. Divided out of 601,375. Drawings to Specification. [Class 106 (i)] A calculating machine has a first control key for conditioning the machine for a particular type of calculation, a second control key for controlling the completion of the calculation, a first interlock for preventing- depression of the second key unless the first is depressed, and a second interlock for preventing depression of the first key if any digit keys are depressed. The machine described is the subtracting and dividing machine described in Specification 601,375. The first control key is a minus key which when depressed conditions the machine for subtraction and changes the method of machine operation from key-responsive to keyset and subsequently operated. After the subtrahend has been set, the second control or " equals " key is depressed to cause subtraction as described in the said Specification. When the minus key is lowered, a bar moves to remove a lug from blocking position below the equals key. Depression of the minus key and also of the division key are prevented, when any numeral keys are down, by means described in the said Specification. Interlocking means between the minus and division keys is described, also means for releasing (for correcting errors) digit keys depressed to set the subtrahend, this release mechanism being operable subsequent to the depression of the minus key and being locked against operation when the equals key is depressed, as described in the said Specification.

Filed: 1971-12-29
Abstract: 1380917 Selective signalling RCA CORPORATION 29 Dec 1971 [28 Dec 1970] 60516/71 Heading G4H [Also in Division H4] A selected channel (e.g. in pay TV), at a remote station is identified by marking the channels in turn and detecting an associated interval in the case of the selected channel to identify the channel, the identification being stored and sent to a central station on interrogation from the central station. The marking is done at the central station and takes the form of interrupting all the channels simultaneously, then interrupting each in turn, and detecting the interval between the two interruptions of the channel in use. Alternatively, the channels are marked with a subcarrier signal in turn, the time at which the channel in use is marked being detected. The remote stations (remote home units), are addressed in turn using address words sent (using high frequency FM), from the central station, the address word comprising a sync bit, a control bit of 0, the address, a parity bit and a disconnect control bit. If the address is not returned from the remote station, the same address is tried again before proceeding to the next address. The data returned to the central station from a selected station consists of a sync bit, the address of the remote station, a parity bit, an indication of the TV channels in use (may be more than one since there can be more than one TV set per remote station), bits from an opinion-polling and purchase-ordering keyboard, a disconnect control status bit and bits from a utility meter and burglar and fire alarm. Transmission back to the central station uses low frequency FM. The disconnect control bit is used to set a disconnect flip-flop in the remote station if its state (as indicated by the disconnect control status bit), is detected (at the central station), as being different from that of a "disconnect" switch on a control panel at the central station. The control panel can also select the remote station to be addressed (which can also be done in an automatic sequence), and display data sent from the remote stations. A computer at the central station can use the returned data for billing purposes. The TV programme is sent over the same lines from the central station. The disconnect facilities can be used to disconnect the TV video at the remote station, or to switch on a jammer for the channel, or to degrade the picture quality (to cause the viewer to ring up the company, when he can be reminded of an unpaid bill). The computer can identify a fault at any remote station and isolate the remote station.
