Title: Improvements in and relating to indicating apparatus
Filed: 1943-02-10
Abstract: 567,100. Indicating; pressure gauges. NEGRETTI, H. N., NEGRETTI, P. E., and IBBOTT, H. W. Feb. 10, 1943, No. 2249. [Class 106 (ii)] A plurality of pressure gauges for indicating respectively different variables are each supplied with gas under pressure through a corresponding gas transmission unit which operates in response to the variable concerned to cause a change of delivery pressure dependent upon the value of the variable, the change being effected by a plate situated adjacent a nozzle affording a small escape of gas so that the pressure builds up to a value balancing at the nozzle a load on the plate derived from the variable. The invention is applied to the instrument panels 27, 28 of an aircraft in which a compressor 1 supplies air through a cooler 2, filter 3 and valve 4 to a distribution chamber 5 through a non-return valve 6. The air is passed through constricted pipes 9 ... 14 to gas transmission units 15 ... 20 of the kind specified. These units may be of the type described in Specification 564,129. The resultant pressure in the unit 15 ... 20 is transmitted to pressure gauges 29 ... 34 and 29<1> ... 341, calibrated in terms of the variables to be measured, e.g. engine r.p.m., oil temperature and pressure, fuel pressure and tank contents, and air temperature. A casing surrounding the instruments communicates through a chamber 37 with casings surrounding the units 15 ... 20, whereby the external pressure conditions in the casings are maintained the same. If the compressor fails, an emergency supply can be effected from a compressed air bottle through a non-return valve 8.

Abstract: 951,395. Controlling change-speed gearing. ROVER CO. Ltd. Jan. 18, 1963, No. 2403/63. Heading F2D. A main change speed gear is followed by a two-speed overdrive controlled by one device when the main gear is in its highest ratio and another device when the main gear is in one or more of its lower ratios. The overdrive is engaged through a solenoid S, acting directly or through pneumatic or hydraulic relay means, the circuit for which is de-energized by switches G1 and GR when the main gear selectors are in first or reverse gear positions. A switch G4 closed only when highest ratio is engaged permits control of the overdrive in top gear by a centre biased steering column switch SC having a contact U to engage overdrive and a contact L to short circuit the solenoid relay R and cause release of a holding contact C2. An inhibitor switch I prevents return from overdrive to direct drive at low throttle openings and a preselector relay P permits this return, without further movement of switch SC, when the throttle is next sufficiently opened. When switch G4 is opened, control of the overdrive is transferred to a switch SP, mounted on the instrument panel, under control of switches G2, G3 operated by second and third speed main gear selectors; the switch G2 closing in the neutral position between first and second gear to allow use of overdrive in the upper three ratios, if desired by switch SP, at all times. A relay Q prevents the direct shift from overdrive third to overdrive top unless overridden by switch SC. A warning light W indicates engagement of overdrive, the light being dimmed at night by relay D in the main lighting circuit.

Abstract: 855,833. Substation equipment. AUTOMATON TELEPHONES (LONDON) Ltd. April 24, 1959 [Jan. 24, 1958], No. 2485/58. Drawings to Specification. Class 40 (4). Phonographic apparatus for automatically answering telephone calls is inductively coupled to the telephone in respect of ringing current, which starts the answering cycle of the apparatus either at once or after a delay, and of speech currents representing both incoming messages to be recorded and a pre-recorded announcement to be transmitted to the calling subscriber. The apparatus includes a support for a telephone, with a solenoid-operated lever which lifts the handset at the beginning of the answering cycle. The pre-recorded announcement is on an endless loop of tape or wire carrying an element which effects the switching in of a wire or tape recorder when the announcement has been transmitted. The apparatus is released a predetermined time after the commencement of a continuous incoming signal (normally dialling tone after the calling subscriber has hung up). This is effected by means of a relay in the anode circuit of a valve of which the grid bias is controlled by a voice-operated relay. The apparatus may be released also by the absence of incoming speech currents for a predetermined time, or by the absence of recording medium through breakage or exhaustion.

Title: Generalized logic circuitry
Inventor: HARMAN MICHAEL GODFREY
IPC: H03K19/177
Filed: 1965-01-20
Abstract: 1,101,851. Logic circuit. NATIONAL CASH REGISTER CO. Ltd. 9 Nov., 1965 [20 Jan., 1965], No. 2556/65. Heading G4H [Also in Division H3] The invention relates to a logic circuit for forming one of a desired range of logical functions and comprises an assembly of logical elements interconnectable in a variety of ways, an input register containing input variables and connected to the elements and a function control register applying control signals to the elements so as to selectively control the interconnections of the elements to cause the desired logical function to be formed at an output of the circuit. One embodiment (Fig. 1, not shown) comprises a matrix of AND and OR gates with horizontal or vertical connections determined by the function control register. A second embodiment (Fig. 2) comprises a matrix of OR gates, the horizontal outputs of which are the sum function and the vertical outputs of which are the inverse of the sum function. The transistor circuits of the latter set of gates are illustrated (Figs. 5, 5A, 5B, not shown) (see Division H3). A permutation matrix (Fig. 3, not shown) is provided to rearrange the order of the input variables so that they are applied to the circuit in the order they appear in the function which it is desired to evaluate. A further embodiment operating in the serial mode (Fig. 9) uses only a portion of the matrix, uses flip-flops in the logic elements and applies the input and control signals via shift registers (Fig. 6, not shown). The logic array used 45 corresponds to a logical unit in the first row of the matrix and two units in the second and third rows of the column immediately to the left of the column containing the first unit. A clock signal to resets the flip-flops. Then during time t, determined by a clock signal K, flip-flop M 1  is set by the incoming signal u which is either 8, the input variable or the inverse of 8 as determined by an inversion signal i. The set and reset inputs to flip-flop M 1  are fed by AND gates 57, 56 respectively with the flip-flops being set, or remaining set if the input u is " 1 " or if the horizontal input from the flip-flop set in a previous clock period is " 1." The flipflop is set zero if u is 0 and there is no horizontal connection at a time determined by clock signal K. Similarly, the set and reset inputs to M 2  and M 3  are fed by appropriate AND and OR gates M 2  being set by M 1 .Y 1 .K and reset by X 2  (M 1  + Y 1 )K, where Y 1  indicates there is a vertical output from M 1 , X 2  that there is no horizontal output from M 2 . The final logical output from M 3  is fed to an inverter 47 where the output can be inverted if required.

Abstract: 425,391. Cleaning metals. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Nerad, A. J. ; 1061, Glenwood Boulevard, and Newkirk, B. L. ; 17, Rosa Road, both in Schenectady, New York, U.S.A.) Jan. 26, 1934, No. 2775. Convention date, Jan. 26, 1933. [Class 82 (ii)] [See also Group XXVI] Comprises a method of cleaning mercury boilers either before or after they have been in operation, and is described in connection with a boiler of the kind described in Specification 418,332, [Group XXVI]. Into a boiler free of mercury is introduced a cleaning or pickling solution such as dilute hydrochloric acid to occupy the place of the normal mercury content for a time to remove deposits. The solution is then removed by flushing with water which in turn is removed by direct displacement of mercury and by heating the boiler to a temperature between the boiling point of water and that of mercury. The drums 12 are connected by equalizing pipes 22 arranged above the cold liquid level. The header 24 is connected to the drums by a conduit 25 ; down tubes 26 and up tubes 28 connect the headers 24, 27. A liquid-mercury feed conduit 36 is arranged above the cold liquid level of the drums. The mercury removed by evaporation is stored in the condenser 34 and a container 39 with cooling means 45. Valves 46, 41, 33 control the vapour conduits 40, 31, and valves 44, 49 the liquid conduits. The drums 12 are connected to the conduit 31 by pipes 29, 30. A slow fire is kept in the furnace to prevent overheating; the valves 41, 33 are opened and valves 44, 49 closed until all the vapour is removed. The boiler is filled with dilute hydrochloric acid for two hours, and is then flushed with water. Valve 46 and a valve 47 in a conduit 48 connected to the equalizing pipe are opened and water is circulated through the drums and maintained at a level near the normal liquid level. Valves 44, 49 are next opened to replace the water by mercury, the water being drained through conduit 48, and the boiler is heated to the desired temperature, the steam leaving the left-hand end of conduit 31. Ammonia may be added to the water to remove the acid. The pickling action may be delayed by the addition of glue, size, or bran.
