Title: Improved control system for internal combustion engines
IPC: F01L13/02
Filed: 1945-06-26
Abstract: 594,091. Controlling reversing-gearing; friction-clutches. GENERAL MOTORS CORPORATION. June 26, 1945, No. 16219. Convention date, June 26, 1944. [Class 80(ii)] [Also in Group XXXIII] In a fluid-pressure engaged clutch or clutches, such as for forward and reverse motion, means are provided to prevent stalling by increasing the engine speed as either clutch is engaged. A driving shaft 15, driven by an engine 3, carries a hollow drum 19 having annular expansible clutch tubes 21, 23, for frictional engagement with drums 25, 27, connected to. shafts 29, 31 adapted to provide, through suitable' gearing (not shown), forward and reverse motion to, for example, a ship's propeller shaft. Fluid pressure is supplied from a reservoir 9 through a pipe 7, restrictor 13 and flexible tube 14 to a control valve 11 which is movable longitudinally to admit pressure to the tubes 21 or 23 through ports 32 or 33 respectively. A tapping 5 is taken from the clutch side of the restrictor 13 and leads to a cylinder 1, having a piston 35 -biassed by a spring 37 and connected by a rod 39 to the speed setting lever 45 of the engine governor 47. A stop 51 limits motion of the piston under the influence of the spring, while nuts 48 provide a lost motion coupling with the lever 45. Under normal running conditions the pressure in all parts of the system is substantially the same and the spring 37 is compressed by the fluid pressure on the piston 35, thereby allowing full movement of the lever 45. When the control valve 11 is moved to engage either clutch, the pressure in the pipes 14, 5 drops, the restrictor 13 preventing immediate make-up of pressure from the reservoir 9, and the spring 37 overcomes the pressure on the piston 35 to move the rod 39 and therefore the governor lever 45 to increase the speed of the engine. The restricted flow through the restrictor 13 then equalises the pressure in the system and normal running conditions from idling to high speed are again restored.

Patent GB-377782-A (GB)
Title: Treatment of fibres with latex and product thereof
IPC: C03C25/00
Filed: 1931-06-04
Abstract: In the addition of latex to fibres, such as asbestos, which tend to coagulate it, protective colloids are added in just sufficient quantity to stabilize the latex at about room temperature but which cease to prevent coagulation when the temperature is raised above approximately 65 DEG  C., and preferably to the boiling point.  The protective colloids include sulphonated oil soaps such as sulphonated castor oil soap or Turkey red oil, sodium silicate, casein, soaps, saponins, h moglobin, serum or egg albumen, the latter colloids being of the type coagulable by heat, and need not be added in such precisely calculated amounts. Fillers such as zinc oxide and graphite, vulcanizing agents and accelerators may be added.  The fibre slurry after heating may be sheeted, centrifuged or collected on a filter screen and dried. If drying is effected without excessive heat or pressure the mass may be redispersed in water.  The rubber content may range from 8 to over 50 per cent of the fibre.  Other fibres which may be treated include cords of tyre fabric, mordanted textile fibres or fibres which have adsorbed finely divided material thereon. Specific examples are given.  Specification 377,785 is referred to.

Title: Pregnadiene derivatives
IPC: C07J71/00
Filed: 1955-06-08
Abstract: The invention comprises esters of 3-ethylenedioxy - 11,20 - diketo - 21 - hydroxy - D 5,16-pregnadiene of the general formula: <FORM:0795452/IV (b)/1> wherein R represents an acyloxy group, and the preparation thereof by reacting 3-ethylenedioxy - 11,20 - diketo - D 5,16 - pregnadiene - 21-oxalyl acid with iodine in the presence of a base and reacting the iodoketone thus formed with a salt of an organic carboxylic acid, e.g. sodium or potassium acetate, sodium propionate or sodium benzoate.  The treatment with iodine may be carried out in two stages, first by reaction in a solution of a weak base, e.g. aqueous disodium hydrogen phosphate, and the reaction is then completed by the addition of a strong base such as potassium hydroxide.  A suitable reaction temperature range is approximately 0 DEG  to 25 DEG  C.  The treatment with the salt of a carboxylic acid may be carried out in a refluxing solvent such as acetone.  The above process may be modified in that the 3-ethylenedioxy-11,20-diketo - D 5,16 - pregnadiene - 21 - oxalyl acid is prepared by hydrolysing an ester of 3-ethylenedioxy - 11,20 - diketo - D 5,16 - pregnadiene - 21-oxalyl acid, and the ester of 3-ethylenedioxy-11,20-diketo - D 5,16 - pregnadiene - 21 - oxalyl acid may be prepared by reacting 3-ethylenedioxy-11,20 - diketo - pregnadiene with an organic oxalate, e.g. dimethyl or diethyl oxalate, in the presence of a basic substance such as an alkali-metal hydroxide, hydride, or alkoxide-particularly sodium and potassium methoxide and ethoxide, a suitable reaction temperature being from 0 DEG  to 100 DEG  C., e.g. room temperature.  The above process may be further modified in that the 3 - ethylenedioxy - D 5,16 - pregnadiene-11,20-dione is prepared by a method claimed in Specification 792,410.  The group R is preferably derived from an alkanoic acid, e.g. an acid containing 2 to 10 carbon atoms.  In the examples, 3-ethylenedioxy- D 5,16-pregnadiene - 11,20 - dione - 21 - ol - 21 - acetate is prepared.  Specification 795,454 also is referred to.

Title: Information reversing method and apparatus
IPC: G07F7/00
Filed: 1963-04-29
Abstract: 991,518. Reversing digital data. SPERRY RAND CORPORATION. April 29, 1963 [May 10, 1962], No. 16689/63. Heading G4C. In a method of and apparatus for reversing a block of serial data signals arranged in a plurality of groups, each group of signals is selectively delayed to reverse the order of the groups and the signals of each group are selectively delayed to reverse the signal order within each group. The arrangement shown in Fig. 2 is effective to reverse individual blocks in a sequence, Fig. 1 of such blocks, each block comprising 30 bits arranged in five 6-bit groups. The arrangement shown comprises a mod-5 counter 212 and a mod-6 counter 214 which each have their first stage operative at the commencement of a reversal operation. The data to be reversed is applied on a lead 210 in synchronism with clock pulses on a lead 276, there being one clock pulse in each bit interval. The first six bits are applied via an AND gate 216 to a 12-bit delay 226 after which an output pulse on a lead 278 from the mod-6 counter 214 is effective to step the mod-5 counter 212 to render its second stage 212-2 operative so that the second group of six bits is fed to a delay 230 while the first group moves to the end of the delay 226. Subsequent data groups are applied to the delays 234, 238 and the output of an OR gate 240, which consists of the reversed groups is applied to a circuit which reverses the bit order within each group. This circuit comprises a series of 2-bit delays 254, 258, 262, 266, 270 which are rendered sequentially operative under the control of the mod-6 counter 214 and a fully reversed block output is produced on an output lead 274. The delay circuits may comprise tube, transistors or magnetic core shift registers or acoustic delay lines, but preferably comprise tracks on a magnetic drum (Fig. 4, not shown). Modifications. In a second embodiment (Figs. 5-7, not shown) the bit reversal takes place before the group reversal. In a third embodiment (Figs. 8a, 8b, not shown), the data block is regarded as divided into groups, sub-groups and sub-subgroups, reversal at these different levels taking place separately; and an end-around feedback is employed to reduce the number of delay elements required.
Patent GB-748291-A (GB)
Title: Improvements in or relating to the manufacture of dithiocarbamates
Filed: 1953-06-17
Abstract: Dithiocarbamates are manufactured by the reaction of carbon disulphide with a primary or secondary amine whereafter, when the reaction mixture has become substantially neutral, an amount of strong alkali substantially equivalent to the amount of amine bound in the form of a salt thereof with the dithiocarbamic acid is added to the reaction mixture to regenerate free amine from its said salt for reaction with residual carbon disulphide, successive additions of strong alkali, each substantially equivalent to the amount of amine salt present, being similarly made during the course of the reaction, as the reaction mixture becomes substantially neutral, until all the amine has reacted with the carbon disulphide.  Aliphatic amines, particularly alkylene diamines, are preferred starting materials. The strong alkali salts of the dithiocarbamic acids so obtained may be converted into other salts by adding, to an aqueous solution thereof, a salt whose cation forms an insoluble or difficulty soluble salt of the dithiocarbamic acid.  Cations specified are iron, zinc, manganese, lead, copper, mercury, cadmium, chromium, magnesium or aluminium.  The products are useful for the control of moulds and insects.  In examples: (1) aqueous ethylene diamine and carbon disulphide are mixed with stirring and successive additions of aqueous sodium hydroxide are made when the liquid becomes neutral until all the amine is used up; (2) the sodium ethylenebisdithiocarbamate so obtained is reacted with zinc chloride solution to precipitate zinc ethylenebisdithiocarbamate.ALSO:Compositions for the control of moulds and insects comprise a dithiocarbamate obtained from carbon disulphide and a primary or secondary amine in a specified manner (see Group IV(b)).  Iron, zinc, manganese, lead, copper, mercury, cadmium, chromium, magnesium and aluminium salts of dithiocarbamic acids obtained from alkylene diamines are mentioned, zinc ethylene bisdithiocarbamate being specified for use against Phytophthora infestans in potatoes.  To the dithiocarbamates there may be added one or more substances which are fillers, adhesives, wetting or dispersing agents and other fungicides or insecticides.

Filed: 1966-04-18
Abstract: 1,129,598. Reading electro-phoretic records photo-electrically. BAUSCH & LOMB Inc. April 18,1966 [May 26, 1965], No.16895/66. Heading G1A. [Also in Division H1]. A circuit for investigating an electro-phoretically migrated sample comprises a photo-sensor whose output is connected to a first logarithmic converter, a second logarithmic converter receiving as input a reference signal, and a differential amplifier receiving the outputs of the logarithmic converters. The output of photo-multiplier 3 receiving light tranmitted through the migrated sample is fed to a silicon transistor 6. The voltage across transistor 6 is proportional to the logarithm of the photo-multiplier current and thus the density of the part of the migrated sample being scanned. This voltage and the voltage across a reference transistor are fed alternately by a chopper 70 to an amplifier 18. The amplifier output is fed via a capacitor 31 and potentiometer to a selector switch 12. In the D position of switch 12, the signal indicative of sample density is connected to the recorder 36. Whilst the density record is being made, the capacitor 42 integrates the density signal. If it is desired to make an integral density record, integrated signal is connected to the recorder and the latter adjusted to read 100%. Capacitor 42 is discharged by closing a switch 66 momentarily and the scan is repeated with the switch 12 in the "integrate" position. The recorder contains an amplifier having variable amplification and variable feedback, which are simultaneously adjusted to normalise the recorder whilst ensuring that it remains stable. When switch 12 is in the position shown, the photomultiplier current is connected directly to the recorder so that the current may be adjusted to lie within a desired range.
