Abstract: 1,038,546. Testing fuel injectors and pumps. E. SATZGER. Sept. 6, 1963 [Sept. 18, 1962], No. 35366/63. Headings F1A and F1B. In apparatus for testing fuel injection pumps in which the test liquid is discharged from a test nozzle 2 into a damping device 4 from which it flows to a graduated vessel through a narrow outlet passage of capillary size between a pin 15 and oulet opening 14, the pin 15 has portions engaging the inner surface of the opening 14 for accurate centring thereof. The liquid is discharged into a chamber 4 having a transparent wall and flows through valve 10 to the space within a tube 6 from which it escapes through orifices 12 to the outlet chamber 13. The surface of the pin 15 may be hexagonal with the edges thereof guided on the surface of the opening 14; alternatively guide ribs may be formed on the pin 15.

Filed: 1970-07-22
Abstract: 1320928 Injection moulding machines CROUZET 22 July 1970 [25 July 1969] 35423/70 Heading B5A In an injection mould any moulded articles which remain attached to ejector rods 8 are displaced by means of the sprue 5<SP>1</SP>a formed in injection passages 5a leading to mould cavities 6, the sprue being given a rotary movement in the space above the rods 8 by means for ejecting the sprue from the passages 5a. This rotation is produced by means of an internally threaded bore 13b in a sprue puller ring 13 and an ejector rod 12. When the rod 12 is moved upwardly by a ram 11 the threaded bore 13b causes the solidified sprue therein to rotate since rotation of the ring 13 is prevented by a key 15. During the initial opening movement of the upper mould portion 1 the ring 13 and the sprue in passages 5, 5a slide upwardly, thereby severing the sprue noses 5<SP>1</SP>b from the moulded articles which remain in the cavities 6.

Title: Improvements relating to fire-extinguishing sprinkler systems
IPC: A62C35/64
Filed: 1928-12-03
Abstract: 326,141. Woosnam, A., (Automatic Sprinkler Co. of America). Dec. 3, 1929. Sprinklers, automatic.-In a sprinkler system in which the main valve is held closed by air pressure in the distributing piping, the expansion of air in a supplemental piping in the fire area is arranged to open a valve to admit pnessure air to the neutral chamber of the main valve, so that the latter may open before the distributing piping outlets open. As shown, a byepass 10 from the air pipe 7 to the neutral chamber 23 is controlled by a valve 11. A system of piping 20 in the fire zone is kept at atmospheric pressure by a "bleeder" 19, carries air expansion bulbs 21, and leads to a diaphragm chamber 18. When air in the bulbs 21 expands owing to fire, the diaphragm 17 moves a detent 16 to release a weight 15 which, in falling, opens the valve 11. The main valve will thus be opened by the increased pressure in the neutral chamber 23 before the sprinkler heads 9 open. An alarm may be given by suitable device when the main valve opens. Specification 327,436 is referred to.

[Class 87 (ii)] Apparatus for producing scored slabs of sweetmeat, such as toffee, composed of pieces with plain or embossed domed tops, comprises a supporting block 1, scoring blades 2<a>, 2<b> carried by the block and arranged to form rectangular enclosures, and a series of ejecting plungers 4 slidably mounted in the block 1 with the head 3 of a plunger located within each enclosure, each head 3 having a plain or embossed concave undersurface. When the block 1 is lifted after being pressed into the sweetmeat, the plungers 4 are actuated by contact with an ejector plate 6. The other blades 2<a> are deeper than the blades 2b, the deeper scoring effected thereby facilitating the initial breaking of a large slab of sweetmeat into smaller slabs each composed by a plurality of scored small pieces.

In an hydraulic or pneumatic braking system of a road vehicle, a pendulum weight 11 is used to control, through linkage 12, a valve element 13 of a control valve 14 so that deceleration of the vehicle causes the valve element to close a by-pass 16a around a differential piston 18 whereby to cause reduction of pressure to the line 16 to the rear wheel brake cylinders, as compared with the pressure supplied via line 15 to the front wheel brake cylinders, and means is provided responsive to the latter pressure, which, as shown, is generated by an hydraulic master cylinder 22, for opposing the action of the weight, so that a delay in the closing of the valve 14 is obtained which is dependent to some extent on the load carried by the vehicle. The means consists, as shown, of a spring 19 which is compressed by a piston 20 to an extent proportional to the pressure in the line 15 which acts on the piston 20 via line 23.

Title: Improvements in or relating to a process for separately recovering an aldehyde or ketone and an aqueous solution of the corresponding alcohol from an aqueous mixture containing the aldehyde or ketone and the alcohol
Inventor: MENTION MAURICE
IPC: B01D5/00
Filed: 1957-11-19
Abstract: An aldehyde or ketone having at least two carbon atoms and an aqueous solution of the corresponding alcohol containing a proportion of alcohol at least equal to that of the azeotrope are separately recovered from a mixture containing the aldehyde or ketone, alcohol and water by introducing the mixture into the lower part of a distillation column such that pure aldehyde or ketone is obtained overhead and a residue free of aldehyde or ketone and alcohol as bottoms, withdrawing a side stream containing aldehyde or ketone, alcohol and water, the proportion of alcohol to water being at least that of the azeotrope and feeding this cut to the head of a second distillation column to obtain aqueous alcohol free of aldehyde or ketone as bottoms.  The overhead from the second column is preferably returned to the first column at about the same level as the side cut is withdrawn. The mixture may be one obtained from the vapours from oxidation or dehydrogenation of the alcohol to give the aldehyde or ketone by condensing and water washing and may contain ethyl alcohol and acetaldehyde, isopropyl alcohol and acetone, propyl alcohol and propionaldehyde or secondary butyl alcohol and methyl ethyl ketone.

Abstract: 325,324. Trent, W. E. Dec. 8, 1928. Coking processes; gas producers. - Solid carbonaceous materials such as coal or oil shale or semi-solid amalgams of coal and oil are distilled or gasified by being heated by heat conductive members such as metal rods to which heat is applied at points away from those at which contact with the material takes place. Metal rods or bars 20 extend through heating chambers 12 and through retorts 14 which contain the material to be treated in trays 26, the rods serving as supports for the trays which are inserted through openings in the end walls of the retorts. Distillates are withdrawn through conduit 28, and the combustion products from the furnaces 34 through flues 40. When operated as a gas producer, air or steam may be introduced into the retorts through inlets 42. The trays may have perforated bottoms to permit of gases circulating through the charge.

A vibrator (4), Fig. 2 (not shown), is adjustably mounted on the hopper to provide radial, tangential, axially or oblique vibration to the hopper to prevent bridging of the material therein. Pressurized air is also supplied to a valve 36, which delivers pulses of air to an impelling valve 3 situated at the outlet of the hopper to form pockets of material 37 alternating with pockets of air in a duct 7. Relay stations 11 are spaced along the duct 7, at a distance less than the column of material which can be moved by the available pressure, to replenish the pockets of air and to supply further air should a blockage occur in the duct. A low level detector 43 in the hopper 1 acts to control the valve 20 to vent the hopper and thereby open the closure member 15 to refill the hopper and start the cycle. The material is discharged into a further hopper 13 with upper and lower level detectors 44, 45 which act to operate the hopper 1.

Abstract: 1502975 Etching PERSTORP AB 5 Sept 1975 [27 Sept 1974] 36747/75 Heading B6J [Also in Division H1] A metal, e.g. copper and zinc, coated insulant printed circuit laminate is coated with an adherent protective layer of plastics or metal, e.g. aluminium, nickel, chromium, tin, lead or their alloys, chemically different from the metal coating, and the laminate is drilled or punched for through holes, the protective layer reducing burr formation and enabling any burrs to be etched off; after which the protective layer is removed. The etchant attacks the burrs but not the protective layer, and may be ammonium persulphate + dilute nitric acid, or dilute hydrogen peroxide and dilute sulphuric acid, or dilute sulphuric acid and chloride ions with electrolysis.
