Patent GB-1602485-A (GB)
Title: Fuel feed pump assembly and its manufacture
IPC: F04D7/00
Filed: 1978-05-31
Abstract: A method for the ventilation of fuel supply pumps as well as a new type of fuel supply pump are proposed which, particularly in pumps having two pumping stages coupled in series within the housing, serve to secure the ventilation of the first pumping stage. Preferably the first pumping stage is embodied as a lateral channel pump which has a forward anterior base plate. The ventilation bore is arranged axially at first in the base plate and in association with the lateral channel and is preferably formed during manufacture in one piece with the base plate; a reduction of the overly-large diameter of the ventilation bore is effected by the insertion of a reduction part to achieve the flow cross section required for ventilation. The ventilation to the outside of the lateral channel stage takes place via an external connection nozzle on the pump housing, which is secured thereon either axially or radially and can be embodied in one piece therewith as necessary. The connection of the ventilation bore of the lateral channel having a reduced cross section with the housing connection nozzle can be made by an elastic medially disposed member.

Abstract: 1,175,103. Sheet stackins; aeration. G. RUUD. 1 June, 1967 [11 June, 1966], No. 25320/67. Heading B8R. Sheets supported on edge on a horizontal base are mechanically aerated to prevent them from sticking together by causing a lifting member to reciprocate across the base thus raising the sheets in turn relative to each other and the base on passage of the member. Fig. 1, illustrates apparatus in which sheets 11 from a printing machine are piled horizontally on a platform 15 carried on an end plate 12 of the apparatus, and then retained by a movable end piece 13, (in dotted lines in Fig. 1). The entire frame 1, comprising the end plates 12, 13 and a base-plate (2) (Figs. 2, 4 not shown) is then pivoted about hinges 18 by means of pneumatic cylinder 16 so that the end plates 12, 13 and the sheets 11 are vertically supported. The lifting member, in the form of a transverse bar 3, is reciprocated longitudinally on a trolley 4 mounted on longitudinal guide rods (9) by means of a screw spindle 8 driven by motor 20. A flexible band 10 may be fixed to the frame 1 and act between the lifting member 3 and the sheets 11, the sheets falling back on to the band under their own weight when the lifting member has passed underneath. The trolley 4 may be carried on vertical bolts (5) which reciprocate under the action of an eccentric (6) on a shaft (23) driven by motor 7, (Fig. 4, not shown) to impart a vibratory motion to the member 3 and hence to the sheets. Further loosening and aeration of the sheets is accomplished by directing an air-blast 21 at the top edges of the sheets, the nozzle moving synchronously with the trolley 4 and the lifting member 3. The lifting member and the flexible bands may be in several parallel pieces.

Filed: 1934-09-03
Abstract: 428,012. Casting composite articles. MORIN, L. H., 215, East 149th Street, and MARINSKY, D., 1515, Grand Concourse, both in Bronx, New York, U.S.A. Sept. 3, 1934, No. 25340. Convention date, Oct. 3, 1933. [Class 83 (i)] Casting - machines; moulds.-In the production of die castings on a mounting strip, as for example in the manufacture of sliding clasp fastener strips, automatic apparatus employed therein involves the use of a pressure fed nozzle, separating die parts and a core element, which serves for feeding and stripping. Part of the mounting member, which is the usual fibrous strip, is positioned between the dies during the casting operation. A trimming tool removes the runner to form a finished element during the operation of the machine. The casting pot and nozzle are heated electrically and the dies are water cooled. The spacing of the fastening elements into groups may be automatic. As shown, a nozzle 28 is urged by the action of a spring 23b against the dies when in working position and is fed by a gooseneck channel 25b from a port 25<c> leading into the interior of the container 25 for the molten metal. A plunger 34 is operated by a cam actuated rocker arm 35<a> to force the metal through the nozzle to the dies and remove same therefrom after an injection to prevent clogging of the nozzle and channels. The pot is electrically heated by means of circuits 32a, 32b which may be provided with switches 41b and a pyrometer 41a. The dies are water cooled to assist speed of operation of the machine and means is also provided for insulating and/or cooling parts of the apparatus, e.g. the casing 24 containing the pot 25 is mounted on rollers which may be supported on water cooled tubular pins. After the injection of a charge of metal into the dies they are opened as indicated in Fig. 10 by cam operated slide bars, the last formed fastening element 43 being still in contact with the core 45 as shown in Fig. 9. Thereupon the core moves downwardly dragging with it the cast element 43 and the mounting strip, the element as soon as the dies partly close being trapped by the lower side 29d of the dies for stripping the core which moves upwardly alone and the dies are opened. The core feeds and spaces the strip for the production of each casting of a series but a separate feed is arranged for spacing each series with respect to the next series, Fig. 15 showing a strip with group castings having a space between the mounting strip 44 being cut between the series to allow of sufficient material for the end parts facilitating attachment to the articles for which the stringers are employed.
