Title: Improvements in the injection of fuel in internal combustion engines
IPC: F02B19/02
Filed: 1920-06-15
Abstract: 169,009. Mõdler, F. L. June 15, 1920. Cylinders receiving liquid fuel.-Liquid fuel is injected into a cylinder 1 by delivering it in measured quantities to a pump 3 to which burnt gases from the cylinder are admitted and highly compressed. The liquid er.ters the cylinder by the same port 10 as the gases enter the pump and it may be sprayed by a jet of gas issuing from the pump by a passage 24, Fig. 3. The invention is applicable to two- and fourstroke-cycle engines, and the fuel may be injected at the beginning or the end of the compression stroke. Each cylinder may have two pumps so that one can be cleaned while the other is in use.

Title: Permanent magnet alternator
IPC: H02K1/27
Filed: 1969-03-28
Abstract: 1,255,067. Machines with permanent magnets. GENERAL LABORATORY ASSOCIATES Inc. 28 March, 1969 [10 April, 1968], No. 16263/69. Heading H2A. A permanent magnet rotor e.g. for an alternator for aircraft, comprises an annular core 12 having peripheral flats 12a against which a ring of bar magnets 14 is clamped by the turned-over rims 20b, 22b of end plates 20, 22, the rims engaging annular washers 24, 26 and the assembly being held together axially by a central, flanged tube 28, spun over at 28a. The ends of the magnets locate in radial grooves in the end plates. Alternatively, Fig. 8, the plates may be flat and the washers, one of which is shown at 260, formed with teeth 260a with intermediate grooves 260b in which the magnets locate. Two sets of magnets may be located axially in line between two end plates and a central plate, Fig. 9 (not shown). Where fewer than 12 magnets are employed, the gaps between them are reduced by stainless steel bars (15) secured alongside the magnets at their outer ends, Figs. 10-11 (not shown), to prevent demagnetization of the rotor by short circuits. The rotor is magnetized after assembly by inserting it in a member wound so as to produce the required polarity and then discharging banks of capacitors through the windings.

Abstract: 1,151,781. Photographic direct positive silver salt materials. EASTMAN KODAK CO. April 15, 1966 [April 15, 1965], No. 16507/66. Heading G2C. A photographic direct positive silver salt material is made by forming cores comprising grains of a first light-sensitive silver salt, treating these cores so as to produce in them centres which promote the deposition of photolytic silver, covering the treated cores with a layer of a second light-sensitive silver salt to form a shell and fogging the resulting emulsion before or after coating on a support. Silver salts specified are silver halides, thiocyanate, phosphate, cyanide and carbonate. The cores are treated to produce the deposition centres by fogging by exposure to light or by chemical sensitization with a gold or iridium or other noble metal sensitizer, a sulphur sensitizer or a reduction sensitizer. The finished emulsion may be fogged by exposure to light of high intensity, by sensitizing to fog by the methods given above, by adding thiourea dioxide or by reduction sensitizing by treatment with excess silver nitrate under controlled conditions of pAg and PH. On imagewise exposure and development, the material gives a direct positive image.

Tip-wagons.-Consists of a tip-cart or wagon wherein simultaneously with the tipping of the body, the centre about which the body pivots traverses an ascending path for the purpose of increasing the tipping of the body. The body 10, Fig. 1, has bowls 11 resting on cam-tracks 12 on side frames 7, between which is mounted a cross-shaft 13 to which is fixed a two-armed lever 14 connected 'by parallel links 15 to the 'body at points 16. Between these points, bowls 17 are mounted on the body to engage in circular slots 18 in the side frames. The shaft 13 is rotated from a hand-wheel 20 through a screwed spindle 19 connected by guided links 22 and a link 26 to an arm 25 on the shaft 13. On rotation of the shaft, the bowls 17 descend the slots 18 and the body tips about the bowls 11. Simultaneously the bowls 11 move along the camtracks 12, the bowls 17 ascending the slots 18 after descending. The bowls 17 and slots 18 may be dispensed with, and the bowls 17 and points 16 may be mounted on members detachably connected to the body. Stops 28 normally hold the bowls 11. The tracks 12, Fig. 3, may be double ended, and the body connected to the side frames 17 by detachable pins engaging in slots 18. On removal of one pin, the body may be pushed over to the other side. The body 10, Fig. 5, is tipped by a lever 37 slotted at 38 to coact with a pin 39 on an arm 40 to allow the lower end of the lever to engage in either side of the shaft 13, which is connected by togglelevers 32, 32 to a bell-crank lever 34 on the side frame, which is slotted to engage a roller pin 36 on the body. To tip the body, the togglelevers are moved above the dead centre 'by the lever 37 and the body pivots on the bowls until cam guides 30 thereon engage rollers 31 on the side frames; whereupon the bowls 11 move up the tracks 12. The bell-crank levers 34 may be dispensed with and the toggle-levers pivoted to the body. The spindle 19, Fig. 1, or any other means may be used for operating the body, and slotted connections may allow free tipping after starting. The body and associated parts may be mounted on a turntable.

Abstract: Carbon-substituted piperazines are prepared by a method comprising contacting an amino alcohol of formula: <FORM:0781701/IV (a)/1> in which R1 is a 1.2 alkylene radical having from 2 to 5 carbon atoms, R2 is an alkyl radical having from 1 to 3 carbon atoms or a phenyl radical, and R3 and R4 are hydrogen, methyl or ethyl radicals, provided that when R2 is an alkyl radical the total number of carbon atoms in R2, R3 and R4 is not greater than 3, with a metallic hydrogenation/dehydrogenation catalyst at an elevated temperature in the presence of water.  Suitable starting materials are, for example: <FORM:0781701/IV (a)/2> which gives 2-phenyl piperazine and: <FORM:0781701/IV (a)/3> which gives 2.6-dimethyl-piperazine. Suitable catalysts are, for example, platinum, palladium, nickel, cobalt, iron, copper chromite and zinc chromite and they may be deposited on supports.
