Title: Manufacture of new therapeutic compounds
IPC: C07F3/12
Filed: 1924-08-12
Abstract: Organo mercury compounds of the formula R-Hg-X, in which R represents a phenolic radicle and X the radicle of a higher fatty acid, are prepared by introducing the higher acyl group into the corresponding hydroxy compound or by replacing the lower acyl radicle of a corresponding organo mercury compound with the higher acyl group. The products, which possess therapeutic properties, are soluble in oils, fats and artificially-prepared fatty acid esters.  According to the examples, (1) 2-hydroxy (or acetoxy)-mercuri-3-hydroxybenzaldehyde is warmed with caproic acid and allowed to cool, when 2-caprooxymercuri-3-hydroxybenzaldehyde separates out; the caproic acid may be replaced by caprylic, lauric, myristic, oleic or chaulmoogric acid; (2) p-tert-butylphenol is boiled with mercuric acetate and the resulting 2 : 6-diacetoxydimercuri-p-tert-butylphenol treated with lauric acid to yield 2 : 6-dilauroxydimercuri-p-tert-butylphenol; other phenolic bodies, such as carvacrol, thymol and p-isoamylphenol, may replace the p-tert-butylphenol, and other higher fatty acids may be substituted for lauric acid; (3) 2-hydroxy (or acetoxy)-mercuri-3-hydroxybenzaldehyde is dissolved in sodium hydroxide solution, or the sodium salt of 2-hydroxymercuri-3-hydroxybenzaldehyde is dissolved in water, and treated with caprylic acid, whereby 2-capryloxymercuri-3-hydroxybenzaldehyde is precipitated.

Abstract: 1,237,299. Driver display unit. BRITISH RAILWAYS BOARD. 15 April, 1970 [17 April, 1969], No. 19704/69. Heading B7N. A visual display unit for a train driver's cab comprises a schematic representation of the route 11 which is moved downwardly past line 12 representing the head of the train in synchronism with the train movement and an indication 14 of the maximum safe speed which is varied in dependence on the signal aspect. The route display is provided on an area 1 of a film of plastics material mounted on reels 15, 16 and driven past a viewing window by motor 17. The motor is controlled by a logic unit 18 which receives signals from an odometer or the like driven from a train axle; the unit also receives signals from, e.g., permanent magnets mounted on the track which are compared with signals received via line 22 from marker points on a magnetic strip 24 alongside the display 1 to provide a film position correcting signal controlling motor 17. The magnetic strip also has four tracks each having recorded along its length the safe maximum speed for a respective signal aspect. The outputs from the four tracks are applied to selection unit 30 and in dependence on signal aspect, as signalled to the train from conductor loops adjacent the track, the relevant maximum safe speed is selected and displayed. Instead of a record of the safe speed the data strip 24 can carry information relating to the track gradient, speed restrictions &c. from which a small computer on the train can calculate, taking into account the class of train, e.g. passenger, fast goods &c., the maximum safe speed. The system can also be used to display in window 36 the number of minutes the train is behind schedule and also to display the maximum speed as a profile or graph.

Filed: 1970-04-24
Abstract: 1311997 Digital storage systems HONEYWELL Inc 24 April 1970 [15 May 1969] 19880/70 Heading G4C In a digital storage system in which certain locations in the store may be defective, means are provided to access an alternative location in the store should a defective location be addressed. Reference is made to core stores and integrated circuit stores.  The store comprises a main part M1 and an auxiliary part M2, Fig. 1. When a computer 1 wishes to exhange data with the store via a data register MDR the address of the relevant store location is placed in register MAR. The address is compared at a time t1 with the address of locations in M1 known to be defective, those addresses being stored in section CMA1 of a content addressable store. If no equality is found the address in register MAR is passed at tine t2 via switching unit 7 to decoder 9 which selects the location in store M1 for transference of data. On the other hand if equality is found a substitute address is read at time t2 from section CAM2 of the content addressable store, the address passing via units 7 and 9 to select a location in the auxiliary store M2 in place of the defective location.  Instead of comparing the address in register MAR with the defective locations addresses prior to transference of data comparison may take place simultaneously. If equality is found the computer undergoes a second cycle, the substitute location in M2 being selected for data transfer. In another arrangement, Fig. 3 (not shown), more than one store is provided, each comprising a main part M1 and an auxiliary part M2, and each addressed via a respective decoder, the circuit being otherwise similar to that in Fig. 1. In this arrangement the addresses in the content addressable store may be changed according to which of the stores is currently addressed, this allowing the use of a small capacity content addressable store. The required set of addresses is called up from a read on y memory when a new store is addressed. The addresses of defective locations and of the substitute locations may be set up in CAM1 and CAM2 by hard wiring, by a keyboard input, or by the computer. If locations in the main or auxiliary stores, or in the content addressable store, become defective during use of the system substitute locations may be provided automatically. An embodiment of the content addressable store, together with the circuitry for setting up addresses and for comparing addresses, is described with reference to Fig. 2 (not shown).

Title: Process and apparatus for the disposal of garbage
IPC: F23G7/00
Filed: 1963-05-21
Abstract: 1,029,174. Refuse incinerators. WISTRA OFENBAU G.m.b.H. May 21, 1963 [May 23, 1962], No. 20113/63. Heading F4B. In a method of waste disposal using a revolving tubular furnace, garbage is dried, ignited and part-burned within the furnace itself, the burning and discharge processes being completed in one or more subsequent stationary or moving grates. The garbage, especially of fine-grained or slurried form, is supplied via feeder 1 to the rotary furnace 2 where it is dried, ignited at discharge end 4 and partly burned. The residue is discharged on to the travelling grate 5 and combustion completed, grate droppings being collected by funnels 12. The slag drops into column 6 and is removed. Preheated combustion air enters the furnace via duct 7 and the resulting flue gases and vapours mix with the flue gases that are evolved by the completion of the combustion process in the mixing chamber 8, the latter gases sterilizing and deodorizing the former. The resultant gas mixture passes through aperture 13 to a heat exchanger (not shown), which may be disposed above or below the grate or grates and which may preheat the furnace air supply. Burners may be disposed near duct 7 to be used intermittently or continuously to preheat. Air for supporting combustion on the grate 5, enters via a duct 9, cools side walls 10 and enters the funnels 12 through apertures 11. This air may be preheated in the heat exchanger and/or mixed with flue gas from chamber 8 and/or vapours evolved in any pre-drying of the garbage prior to its entry to feeder 1.

Title: Energizing Circuit for Degaussing Apparatus.
IPC: H04N9/16
Filed: 1967-05-01
Abstract: 1,170,137. Cathode-ray tube circuits. RADIO CORPORATION OF AMERICA. 1 May, 1967 [3 May, 1966], No. 20118/67. Heading H4T. In an arrangement for automatically degaussing a television picture tube, particularly a shadow-mask colour tube, a capacitor connected to one terminal of a degaussing coil is charged through the coil during alternate half-cycles of the A.C. supply for the apparatus and discharges through the coil into a second capacitor connected to the other terminal of the coil during intervening halfcycles of the A.C. supply. The cyclic reversal of the direction of current flow through the coil thus produces an alternating magnetic field, the magnitude of which decreases towards zero as the second capacitor becomes fully charged. For carrying out the invention a conventional voltage doubler type of circuit supplying the television apparatus with the normal D.C. operating potentials from the A.C. supply is modified as shown in Fig. 2. This modification involves replacing the input capacitance of the circuit by two capacitors 16, 17 and the provision of a linked switch 24-27 mechanically biased by resilient means 35 so that it normally occupies the position shown involving contacts N(= normal). In this position the circuit operates in conventional manner to provide operating D.C. potentials viz. 280V and 140V for the television receiver 15. When degaussing of the picture tube is required, the switch is operated to its other position in which contacts D(=degaussing) are engaged and then allowed to return to its normal position under the action of the resilient means 35. During the short interval for which the D contacts are engaged capacitor 16 is charged through the degaussing coil 13, 14 by alternate half-cycles of the input A.C. (via switch 19) whilst during intervening half-cycles capacitor 16 discharges through coil 13, 14 into a second capacitor 23. This charge and discharge of capacitor 16 continues until capacitor 23 becomes fully charged and the resulting alternating magnetic field produced by coil 13, 14 effects the required degaussing of the picture tube. The coil 13, 14 is mounted on a magnetic shield 12 (Fig. 1) of ferrous metal with the forward portions encircling the shield on the outside and the rear portions disposed on the inside of the shield. Values for the various capacitors are given.
