Title: Absorption refrigeration machine control
IPC: F25B15/04
Filed: 1970-04-10
Abstract: 1,262,255. Refrigerating. CARRIER CORP. 10 April, 1970 [2 June, 1969 (2)], No. 17253/70. Heading F4H. In an absorption refrigeration system, heating of the generator is prevented if a predetermined solution level is not attained in the generator. Overheating of the generator is thus avoided. As illustrated, a system using ammonia as refrigerant and water as absorbent comprises a generator 16, condenser 12, evaporator 32 and absorber 10. Strong solution is passed from the generator to the absorber through an inner pass of a heat exchanger 64 located in a rectifier 68, weak solution being returned to the generator through an outer pass of the heat exchanger 64. The generator is heated by gas burners 73 to which fuel is supplied through a valve 74. If a generator probe 87 is immersed in solution, then the resultant electrical capacitance between lines C and D acts through a controller 86 to open the valve 74. If the probe is not immersed, then the valve 74 is closed. Action of the controller does not affect the operation of a condenser/absorber cooling fan motor 59 or of a weak solution pump motor 19 which, together with the controller, are energized by a room thermostat 77.

Title: Electrical protective relays
Inventor: HUMPAGE WILLIAM DEREK
IPC: H02H3/40
Filed: 1964-04-28
Abstract: 1,096,412. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. April 28, 1965 [April 28, 1964], No. 17652/64. Heading H2K. A distance protective arrangement comprises comparators 32, 33, each for comparing at least two input signals proportional to different vectorial quantities derived from the protected system and for producing output signals for energizing a control device which produces an alarm or protective signal when any portions of the output signals are coincident in time. At least one of the comparators is an asymmetrical comparator, that is a comparator which is sensitive to the phase sequence of its input signals in addition to the phase angle between them and produces an output signal when the input signals occur within different predetermined phase angles lying on opposite sides of a predetermined vector quantity. Fig. 1 shows a multi-zone protective arrangement and includes a third comparator 34. In the event of a fault, the comparators 32, 33 provide outputs which operate an AND gate 37 to provide an output signal P. Should the fault be within a first zone, the comparator 34 provides an output Q causing an AND gate 38 to provide an output which through an OR gate 40 effects the tripping of a circuit-breaker 11. Should the fault be in the second zone, the comparator 34 does not provide its output signal Q until after a predetermined time delay provided by a timer 41 which is energized by the signal P and modifies a signal generator 22 to increase the reach of the comparator 34. If, however, the fault is in a third zone, the timer 41 after a longer time delay provides a signal directly to the OR gate 40 to effect tripping of the circuit-breaker. The Specification describes the comparators and with the aid of vector and impedance diagrams explains the relay characteristics.

Title: Process for the preparation of substitution products of 2:5-dihydrofuran
Filed: 1945-07-11
Abstract: Dihydrofuran derivatives of the formula <FORM:0595041/IV/1> where X and Y may be hydrogen or substituent groups free from olefinic linkages and R is an aliphatic or alicyclic group, are prepared by reacting furan or a substituted furan with bromine or chlorine and an aliphatic or alicyclic mono-, or dihydric hydroxyl containing compound.  A preferred form of the invention is when X is hydrogen, methyl or carboxymethyl and Y is hydrogen or methyl. Instead of chlorine or bromine, compounds which yield halogen under the conditions of the reaction may be used, such as tertiary butyl hypochlorite or bromonitro-methane.  Alcoholates may be used instead of the hydroxyl containing compound.  When hydroxyl compounds containing more than six carbon atoms are used, it is preferred to carry out the reaction in the presence of an organic solvent, such as tetrahydropyran, tetrahydrofuran, tetrahydrosylvan, chloroform and other saturated chlor-hydrocarbons.  Compounds mentioned as being prepared by the process of the invention include 2 : 5 - dimethoxy - 2 : 5 - dihydrofuran, 2 : 5 - dimethoxy - 2 : 5 - dihydrosylvan and 2 : 5 - dimethoxy - 2 : 5 - dimethyl - 2 : 5 - dihydrofuran.  These compounds were characterised by the preparation of their bis-2 : 4-dinitrophenyl hydrazine derivatives by hydrolysis of the corresponding 2 : 5-dihydrofuran compound and warming the product with a methanol solution of 2 : 4-dinitrophenylhydrazone.  In examples: (1) chlorine is passed into a methanol solution of sodium carbonate and furan to saturation.  Distillation of the product gives 2 : 5-dimethoxy-2 : 5-dihydrofuran; (2) as in example (1) using methyl fuorate to produce 2 : 5-dimethoxy-2 : 5-dihydromethyl furoate.  A sample has been furnished under Sect. 2 (5) of 2 : 5-dimethoxy-2 : 5-dihydrofuran prepared by heating furan and methanol with chlorine and soda ash in the presence of carbon tetrachloride as solvent.

Title: Coordinate determining system
IPC: G06F3/033
Filed: 1971-05-28
Abstract: 1343699 Position finding; ultrasonic probes INTERNATIONAL BUSINESS MACHINES CORP 28 May 1971 [18 June 1970] 17821/71 Headings H4D and H4J [Also in Division G4] The co-ordinates of a probe on the surface of a sheet of material are determined by timing the passage of ultrasonic waves to the probe from each of two ultrasonic vibration generators coupled to the sheet, the two generators being energized in turn by applied sinusoidal electrical signals.  In the Fig. 1 and 2 embodiments the waves are launched as pulses by generators 12, 14 in a glass or plastics sheet 10 used as an overlay for a graphical display or as the faceplate of a CRT. The time between pulses is sufficient to allow spurious reflections from the sheet edges to be damped out. An initiation signal, e.g. from a computer, from a push-button, or from closure of a switch as the tip of tranducer probe 16 is applied to sheet 10, triggers drive control 44 of the Fig. 3 circuit to gate a sine-wave signal pulse from source 46 to generators 12, 14 in turn and to start the timing. The first cycle of acoustic wave energy reaching probe 16 is sensed by detector 54 and stops the timing. Counter-timers 34 and 36 thereby register counts proportional to the probe distances from generators 12 and 14, respectively. These counts may be converted to Cartesian, polar or other coordinates if required. For providing a count directly indicating Cartesian co-ordinates, generators 12 and 14 may be replaced by two linear arrays of transducers, the arrays extending along respective, perpendicular edges of sheet 10 (Fig. 4, not shown). Details are given of a logic circuit system (Fig. 5, not shown) for controlling the following sequence: (a) the gating, at a particular point in the sine-wave cycle, of the sine-wave signal to one vibration generator, and the starting of one countertimer, (b) the stopping of the counter-timer on receipt of the acoustic pulse at probe 16 or, if the pulse is not received by the time the countertimer has reached its maximum count capacity, the re-energization of the same vibration generator for a second or further measurement attempt, (c) when a valid count has been obtained, the gating of the sine-wave signal to the second vibration generator, and the starting of the second counter-timer, (d) the stopping of the second counter-timer, or re-triggering of the second vibration generator as in b above, (e) the production of a "data-ready" signal when both counter-timers have registered valid counts. Transducer details (Fig. 2).-Generator transducer 12 is rigidly epoxybonded in sheet 10, is tubular in form, and vibrates in its length direction. The probe comprises a silvered lead zirconate titanate tubular transducer 16 (operating in a similar mode) in a flexible plastics casing 22, or cemented by soft epoxy within a rigid casing. A spherical, or hemispherical, probe tip 24 of ceramic, ruby, or sapphireprovides an approximate acoustic impedance match between the probe and sheet 10.
