Title: Improvements relating to data storage arrangements
Inventor: HOUNSFIELD GODFREY NEWBOLD
IPC: G11C11/06
Filed: 1968-03-25
Abstract: 1,255,629. Magnetic storage apparatus. E.M.I. Ltd. 3 March, 1969 [25 March, 1968], No. 14300/68. Heading H3B. In a matrix in which two plates of non- magnetic material are placed face to face so that parallel grooves lined with magnetic material 1, 2 in the two facing faces of the plates are orientated orthogonally to each other and at least one conductor 3, 4 is positioned in each groove 1, 2 a binary storage element is formed at each crossing point region consisting of two closed magnetic storage loops 6, 7 around respective diagonals. One loop represents one binary state and the other loop represents the other binary state. The magnetic material may be isotropic and/or anisotropic with the easy axis lying along the groove. In order to write a digit into the storage element shown in Fig. 1 a pulse is applied to word address conductor 4 simultaneously with a smaller current of one polarity or the other depending on the digit to be stored to digit drive/sense conductor 3. The combined fluxes produce magnetization round one or other of the diagonals closed loops 6, 7 representing a " 1 " or " 0 ". In order to read out a pulse is applied to address conductor 4 of opposite polarity to that used for writing to produce a magnetic flux in the portions 1, 2 indicated at 5 so that the magnetic flux linking conductor 3 is reduced to zero. The change in magnetic flux induces a voltage in sense conductor 3 the polarity of which represents the digit stored. Separate sense and digit conductors may be used. Only one of the magnetic portions need be formed of magnetic remanent material the other portion being made of non-remanent magnetic material. Two storage elements may be used to store each binary digit in which case the respective digit drive conductors through each pair are driven differentially and the address conductors driven as before.

Abstract: 1,107,381. Selective signalling. GEORGE RICHARDS & CO. Ltd. 9 April, 1965 [10 April, 1964], No. 14983/64. Heading G4H. In a device for converting a position into a phase-modulated pulse train by means of a photo-electrically sensed incremental scale, a scale of 10 lines/inch is used so that one cycle of phase variation corresponds to the relatively large distance of <SP>1</SP>/ 10 th inch, and the output pulses produced are strobed by pulses produced by a 100 lines/inch scale, whereby the resulting output signal has a phase cycle corresponding to the coarse scale but a tolerance or accuracy corresponding to the fine scale. This feature is of particular advantage in the position control system described in Specification 966,379, which is referred to, since, as a result, a larger difference between the desired position and the actual position of the controlled member, can be accommodated in the control loop.

Title: Tube-ice machine
IPC: F25C1/06
Filed: 1947-06-07
Abstract: 632,966. Ice-making. KUBAUGH, B. F. June 7, 1947, No. 15074. Convention date, Jan. 28, 1944. [Class 29], [Also in Group XXIX] In an ice-making apparatus in which tube ice is formed in a vessel in an evaporator of a compressing and condensing system, the ice is freed from the vessel by firstly connecting the condenser to the evaporator to drive some of the refrigerant liquid into a receiver and secondly connecting the suction side of the compressor to the condenser and receiver and the pressure side of the compressor to the evaporator. To freeze ice in tubes 11 in a flooded evaporator 2, the compressor 1 supplies gas by a pipe 8 including a valve 21 to a condenser 3 whence the liquid refrigerant flows by way of a vessel 4 and a pipe 9 to the evaporator 2. The suction line 5 includes a stop valve 6. The pipe 8 is connected to the evaporator by a pipe 16 including a valve 17 and to the suction pipe 5 by a pipe 22 including a valve 23. A receiver 14 is connected to the suction line 5 by a pipe 19 including a valve 20 and to the bottom of the evaporator by a pipe 15. In the freezing stage the valves 17, 20, 23 are closed and the valves 6, 21 open. To free the ice, the valve 6 is closed and the valves 17, 20 opened whereupon gas from the condenser passes to the evaporator by pipes 8, 16 to force liquid refrigerant into the receiver 14. Valve 21 is then closed and valve 23 opened whereupon suction is applied to the condenser through pipes 22, 8 and to the receiver 14 by pipes 5, 19 and hot gas is forced into the evaporator by way of the pipe 16. The valves are solenoid operated in correct sequence through mercury switches actuated by rotating cams on a common controller shaft. As shown in Fig. 3 the valves 21, 23 are replaced by a single three-way valve 27 actuated in dependence on the pressure in the pressure line 8. The valve member 28 of valve 27 is moved by a shaft 29 attached to a diaphragm 30 which is influenced by the pressure in a pipe 35,leading from another three-way valve 34. An input to the valve 34 from the line 8 is provided by pipe 36 and from the suction line 5 by pipe 37. The valve 34 is operated by a solenoid 33 energized when the pressure drops in line 8 by pressure responsive device 32. In the freezing period line 8 is under pressure and the solenoid 33 is not energized and thus the diaphragm 30 is under low pressure from the suction line 5 by way of pipe 37, valve 34 and pipe 35. Thus the valve 27 connects the pressure line to the condenser. In ice freeing, the valve 17 is opened and the pressure in the pipes 8, 16 drops and when it has become sufficiently low the solenoid 33 is energized to move the valve 34 and put the diaphragm 30 under high pressure by way of pipes 8, 36 and 35. In this position, the valve 27 connects the condenser 3 to the compressor suction line 5.

Abstract: 420,087. Variable-speed gearing. RUSHFIRTH, S., 4, Dorset Road, Lytham-St.-Annes, Lancashire. May 25, 1933, No. 15083. [Class 80 (ii)] Relates to variablespeed gearing suitable for vehicles of the kind comprising aligned driving and driven shafts 7, 12 over the adjacent ends of which is mounted a housing 8 rotatable relatively to both shafts and carrying one or more countershafts 24 with alternative trains of gearing for connecting the countershafts to the main shafts there being centrally moving toothed gear and clutch elements such as 31, 32 therefor and a brake 47 for securing the housing 8 against rotation during countershaft drives. A friction clutch 37 to facilitate gear changing on all ratios is arranged directly between and for coupling together the two main shafts 7, 12, instead of being circumferentially arranged as in the arrangement of Specification 347,788. In addition to two reduced forward speeds and reversed drive with the brake 47 applied, there is a solid high-speed drive with the brake disengaged effected by engaging clutch teeth 38 on the friction clutch member 37 engaging clutch teeth 39 on the driven shaft 12. The member 37 turns with the shaft 7 and is controlled through a central rod 40 from a striking ring 41 which is biassed to the left to engage the top speed clutch 38, 39 by a spring 45. Suitable connections interpose a distance piece, not shown, behind a stop 46 when the brake 47 is engaged to prevent the clutch 38, 39 being engaged during countershaft drives. The ring 41 is engaged at 42 by a connection to an engine clutch, not shown, so that at each disengagement of the latter, the synchronizing friction clutch 37 is engaged, the brake 47 being then always released, so that all parts within the casing rotate with little relative motion to the end that change of mesh can be effected without shock. On release of the clutch pedal, the clutch 37 is disengaged and the drive picks up on the new speed.

Filed: 1978-04-18
Abstract: The composition contains as active constituent a dicarboxylic acid containing between 7 and 13 carbon atoms or one of its derivatives with at least one reducing functional group in the molecule. For the preparation of the active constituent in the form of a mercaptoderivative, the bromine derivative is prepared with a number of substituting bromine atoms equal to the number of mercaptogroups to be inserted, and the bromine derivative is reacted with thiourea and ethyl alcohol to form the alkylthiouronic salt which, by saponification, forms the corresponding mercaptoderivative. The composition according to the present invention can be applied topically in the form of creams, pomades, ointments and lotions. The compositions according to the present invention have proved capable in particular of inhibiting the formation of the cutaneous pigment (melanin) by blocking the dopa-tyrosinase reaction by a competitive mechanism.

Abstract: 593,836. Hydraulic intensifiers. TAYLOR, A. H. June 15, 1945, No. 15219. Drawings to Specification. [Class 69 (ii)] A low pressure intensifier unit for hydraulic presses and the like comprising a plurality of intensifiers coupled together hydraulically and electrically whereby operation of the press causes one intensifier to commence to build up high pressure and at the end of its stroke to automatically introduce a further intensifier until the predetermined high pressure is attained. When the press is fully closed by low pressure liquid a switch operates a solenoid which opens a distributing valve to supply low pressure liquid to the intensifiers, the first of which is at the bottom and the second at the top of its stroke, a switch on the latter then actuating a solenoid operated valve to admit liquid to the first intensifier. As the ram of the first intensifier rises it actuates a solenoid operated valve on the second intensifier, thereby opening it to exhaust. As the first intensifier nears the top of its stroke it again operates the switch which controls the valve on the second intensifier, this time opening the valve to admit low pressure liquid to the latter. The ram of the second intensifier commences to rise and when the predetermined high pressure has been attained, a switch opens to operate the solenoid which closes the distributing valve thereby cutting off supply of liquid to the intensifiers.

Abstract: 850,691. Cooling aircraft tanks. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. April 22, 1958 [May 14, 1957], No. 15234/57. Class 4. [Also in Group XXVI] An aircraft has an engine nacelle formed in two relatively movable parts, one of which forms or houses a tank for lubricant or other liquid, so that the cooling effect of the ambient air can be varied by relative displacement of the parts. The Figure shows a half axial section of the forward portion of a nacelle forming the air intake of a gas turbine engine. A fixed part 2b is hollow, forming an annular engine lubricant tank, and a part 2a is axially movable by three double acting circumferentially spaced hydraulic jacks 6 (one shown). With the jacks in the extended position shown, an annular duct 5 is formed between parts 2a and 2b, to permit ambient air flow into the engine compressor intake as shown by arrows C, raising the surface area of the tank over which heat exchange with the air may take place. The jacks may be retracted during normal flight, when the airflow outside the nacelle is sufficient to cool the lubricant, and extended during low speed flight. Hot de-icing gases are led to the part 2a through telescopic tubes (see Group XXVI), these tubes being thermally insulated to prevent heating of the tank or the cooling air.
