Title: Data acquisition and identification system
IPC: G06F17/40
Filed: 1970-10-01
Abstract: 1325736 Electric signalling systems GENERAL ELECTRIC CO 1 Oct 1970 [2 Oct 1996] 46734/70 Heading G4H A data acquisition and identification system adapted to monitor a plurality of signal sources 11a-11n comprises a receiver 13a-13n for each source responding to a change of signal to generate an "event flag" signal, gating means having inputs connected to the receivers, providing a signal in response to an event flag signal from any receiver which signal causes a search to be made to identify the receiver generating the event flag. The signals from sources 11 are converted at 12 to some form suitable for transmission having for example only two signal levels. A change of level in any signal causes the corresponding circuit 13 to give the event flag signal, which is also a change of signal level. Several circuits 13 are connected to each of a number of first level selectors 14a &c. The outputs of selectors 14a &c. are connected in groups to a smaller number of second level selectors 15a &c. which are in turn connected to a master level selector 16. An event flag signal is transmitted through selectors 14 and 15 to the master selector 16 which passes a signal to the address scanner and transfer buffer unit 17. The time at which an event flag signal is received is given by the count of a continuously running counter which is transferred to the unit 17. A scanning operation is initiated by the event flag signal to find the line carrying the signal. For this purpose an address counter responds to the event flag signal to begin a systematic search of the second level selectors 15. When the selector through which the event flag signal has come has been found, the first part of the search is stopped and a search is made of the inputs to this selector using a second address counter. When the particular input is found a third address counter is started to scan the inputs to the corresponding selector to find the particular receiver. The direction of the change of level of the signal giving rise to the event flag signal is converted to a marking or a mark on one of two leads and entered into the buffer of unit 17. The data accumulated in the buffer of unit 17 is passed to a computer 18 which may, for example, be a process control computer. The gating arrangements of the various selector circuits are described in detail.

Abstract: 1,024,289. Integrated semi-conductor circuits. STANDARD TELEPHONES & CABLES Ltd. Nov. 17, 1964, No. 46748/64. Heading H1K. In a monolithic semi-conductor integrated circuit, wherein devices are formed in a first region having an insulating region thereon and overlying a second region of different conductivity type, channels are etched about each device so as to form at least part of an insulating means around the device, but the etching is such that the insulating region is left intact and receives a metallized connection pattern thereon. In a modification a channel is etched around the device but a narrow neck is left the material of which is converted to the conductivity of the second region (Fig. 6, not shown). In a specific embodiment, Fig. 3, a P-type silicon substrate 2 has an N-type epitaxial layer 1 deposited thereon, an N+region 9 being provided in substrate 2 to reduce internal resistance. A transistor device is incorporated in layer 1 comprising a P-type base 5, an N-type emitter 6 and an N + collector contact 7. Moats 10 are etched in layer 1 and substrate 2, isolating the device and thus lowering the capacitance. The isolating moats are made by etching silicon away from under the insulating region leaving " bridges " of insulating material to receive the metallized pattern.

Title: Improvements relating to fluid heating systems
IPC: F24D3/02
Filed: 1963-11-27
Abstract: 1,028,179. Fluid heating systems. J. W. DAVISON. Nov. 20, 1964 [Nov. 27, 1963; April 14, 1964], Nos. 46868/63 and 15459/64. Heading F4U. [Also in Division F1] In a fluid heating system having a fuel fired fluid heater (not shown), the means for driving the fluid through the system comprises a fan, or as shown, a circulating pump 7 driven by a turbine 13 in a closed circuit, this circuit including an evaporator 12 and a condenser 10 for a motive fluid and a pump 20 driven directly by a turbine shaft 14 for transferring the motive fluid from the condenser to the evaporator. Hot fluid from the heater passes through a pipe 1 to the heating coil 2 of the evaporator and leaves by a pipe 3. A by-pass 4 with a valve 5 controls the amount of fluid flowing through the coil. Cool fluid flowing back to the heater passes to a cooling coil in the condenser via a pipe 8. If the fluid in the system is air then the incoming cool air cools the condenser. The motive fluid in the closed circuit is of low boiling point, e.g. trichloromonofluoromethane, and the difference in its vapour pressure between the condenser and evaporator is sufficient to drive the turbine. The end of the turbine shaft 14 remote from the pump 20 enters a gear-box 23 containing an epicyclic reduction gear and the output shaft 24 carries a driving element 25 which forms part of a magnetic coupling used to drive the circulating pump 7. If the circulation system uses air then a fan will be used in place of the pump 7. In an alternative embodiment of the invention the turbine may be used to drive a permanent magnet alternator providing power to drive an electric fan or pump. Auxiliary equipment such as extra fans, indicator lamps, and ignition apparatus may also be driven with the electric power provided. If the heating system employs an oil-fired burner then the starter battery may be charged by the generated current. The condenser is disposed at a higher level than the evaporator thereby providing a pressure difference across the turbine to allow automatic starting on the supply of heated fluid to the evaporator.

Abstract: In producing malt wort, malt is comminuted, preferably to a particle size not exceeding 0.05 mm., and continuously subjected to continuous sequential mashing operations, including heating to an elevated temperature to cause saccharification and cooking of the mash (if necessary), and the resulting mashed mixture is subjected to concomitant suction and filtering in order to recover the wort.
