Title: Fuel injection systems
IPC: F02M51/00
Filed: 1970-05-14
Abstract: 1310596 Fuel injection systems SOC INDUSTRIELLE D'ELECTRONIQUE ET D'INFORMATIQUE 14 May 1970 [14 May 1969] 23513/70 Heading G1N [Also in Division F1] In an I.C. engine fuel injection control system, fuel pumped from a supply is applied to an injector B, Fig. 1, and to a drain, a valve V in the drain being periodically closed to cause pressure build-up of fuel at the injector to overcome the valve bias of the injector and thereby inject fuel. The closing of valve V is controlled by a circuit, Fig. 2, the valve closing at a point determined by engine speed (e.g. by determining mass flow of air in the inlet manifold, Fig. 9 (not shown)), or by the pressure in the inlet manifold, and opening again at a point determined by the engine load, e.g. the position of the accelerator pedal. As shown, Fig. 2 injection pulses are timed by a timer 136 controlled by the engine, the injection pulse 57 being provided by a flipflop 52 set by a flip-flop 39 which produces a pulse 44 dependent upon engine speed (potentiometer 46), and reset in dependence upon the engine load (potentiometer 55). When applied to a multi-cylinder engine, Fig. 7, operation of each injector B1-B4 is controlled by a series of valves A1-A4 and a logic network Fig. 5 (not shown). Each of the valves A1-A4 Fig. 4 (not shown), includes the valve V shown in Fig. 1 and a further valve which blocks its respective injector from the fuel supply when injection in that cylinder is not required. The logic network has three inputs I 1 -I 3 , I 1  being dependent upon engine crank angle to provide the sequency of operation of the injectors, I 2  being dependent upon engine speed, and I 3  on engine load. However, injection may be controlled independently of the inputs I 2  and I 3 , e.g. during cold starting. The valve V may be provided with an additional electromagnet, Fig. 5 (not shown), this electromagnet being insufficient to overcome the bias of valve V but being operated just before the electromagnet 22 so that rapid operation of the valve V is ensured.

Title: Improvements relating to the separation of minerals and other substances
IPC: B03B5/18
Filed: 1925-09-21
Abstract: 268,043. Davidson, T. M. Sept. 21. 1925. Separating by shaking apparatus. - In the washing and separation of mineral and other substances the material in a finely divided condition is fed from a hopper n to the upper part of an inclined tray b<1> the inclination of which may be varied. This tray, which has a transverse wall b<5> at its lower end, is adapted to be transversely reciprocated and is supported upon a frame carrying an endless belt b which is transversely reciprocated and the upper length of which in the form shown moves upwardly through water contained in a tank a. Tensioning devices h<3> are provided for the belt and screwed spindles i<3> for adjusting its inclination. It is driven from a shaft l, through worm-gear, a shaft l<3>, adjustable friction wheels l<4>, l<5>, and pinion gear l<7> connected to the belt supporting rollers c. The rollers have splined connections with their shafts to permit the transverse reciprocation of the belt. The transverse movement is given from the shaft l through adjustable friction gear m<2> and a shaft m carrying eccentrics the straps of which are connected to the frame carrying the belt. Cushioning springs are interposed between the belt supporting rollers and the reciprocating gear. The material gradually passes down the tray b' and the lighter materials pass over the transverse wall b<5> the heavier particles passing through a slot in the lower part of the wall. The heavier particles thus fall on to the belt b higher up than the lighter ones. The heavier particles are carried upwards by the belt and discharged over its upper end into the liquid where they are collected. A small water spray may be applied at the upper end of the belt above the water level. The lighter particles pass downwards and accumulate against a rubber apron b<7> finally passing over this apron into the liquid at the end of the tank where they can be separately collected. The tray and the conveyer may be separately inclined and the material to be treated may be passed through a series of separating devices.

Title: Fusion welding method and apparatus
IPC: B23K9/007
Filed: 1964-06-08
Abstract: 1,059,394. Welding by fusion. D. SCIAKY. June 8, 1964 [July 18, 1963], No. 23583/64. Heading B3R. In arc spot welding a flange to a panel the electrode is located to fuse the edge of the flange and the panel by a shoe engaging the panel and the flange edge. An inert gas shielded tungsten electrode welding head (71), Fig. 2, not shown, is pivotally mounted on a slide (32) mounted in guideways on a pneumatic cylinder (18) and reciprocated by the piston of the cylinder. The welding head is adjustable about its pivot by a threaded device (61). The cylinder (18) is pivotally mounted on a fixed frame (10) and is adjustable about its pivot by a pneumatic cylinder (20). In operation the cylinder (18) lowers the welding head (71) until a shoe (64) mounted on the head engages the panel. The head (71) and cylinder (18) are then pivoted by the cylinder (20) until the shoe engages the edge of the flange. Initiation and timing of the arc are effected automatically. Prior to welding, a blast of air issues from a pipe (70) connected to the shoe to clean the weld area. After welding the cylinders (18) and (20) return to their initial positions. The shoe (64) may be shaped to project over the upper surface of the flange. In a modification, Fig. 10 (not shown), the welding head (127) and the shoe (130) are mounted in an oblique slideway (116) supported on a splined shaft (112) connected to the piston rod of a pneumatic cylinder (105) having a splined end (107) engaging the shaft (112). The end (107) is mounted so as to be adjustable axially and angularly. The work is moved up against the welding head and moves the welding head in the slideway (116) against spring action so that the shoe (130) moves transversely of the work to engage the edge of the flange. Further lifting of the work is taken up by the pneumatic cylinder (105). In a further modification the welding head is pivotally mounted so as to be reciprocable relative to the shoe and parallel to the edge of the flange to effect an elongated spot weld.

Title: Process for purifying progesterone preparations
IPC: C07J5/00
Filed: 1935-08-22
Abstract: The hydroxylated impurities are removed from crude progesterone preparations by treatment of the preparations with an acylating agent followed by separation of the portion which has entered into reaction from the non-esterified portion which contains the progesterone. Suitable acylating agents which yield sparingly soluble esters with the oxyketones are benzoyl, nitrobenzoyl, dinitrobenzoyl, and phenylbenzoyl chlorides, phenylisocyanate, diphenylisocyanate, and phosgene.  It is preferred, however, to use agents which in addition to the acylating group, contain a salt forming group or a group which can be transformed into a salt forming group such as phthalic and maleic acid anhydrides, oxybenzoic acid chlorides, chlorosulphonic acid, phosphorus oxychloride and alkyl-meta-phosphates.  In examples: (1) a crude progesterone crystallisate is reacted with phthalic anhydride in an atmosphere of nitrogen, the aqueous solution extracted with ether, and the ether extract washed with hydrochloric acid and water.  Evaporation of the ether and recrystallization of the product yields progesterone in two polymorphous forms.  The hydroxylated compounds may also if desired be extracted from the aqueous solution; (2) a crude progesterone crystallisate is reacted with 2 : 4-dinitrobenzoyl chloride in quinoline solution, the product mixed with water, extracted with ether, and worked up to yield the two polymorphous forms as in example 1; (3) a progesterone crystallisate is reacted with phthalic anhydride in pyridine, and worked up as in example 1.

Title: Improvements in or relating to hydraulic telemotor systems
IPC: F01L9/11
Filed: 1937-08-30
Abstract: 501,738. Hydraulic transmission of power; valve gear. SCHWEIZERISCHE LOKOMOTIV-UND MASCHINENFABRIK. Aug. 30, 1937, No. 23663. Convention date, Sept. 2, 1936. [Class 69 (ii)] [Also in Group XXVII] A hydraulic telemotor system, of the kind in which the transmitting piston is reciprocated intermittently but at regular intervals so as to impart a regular but intermittent movement to the receiver piston and therefore to the member actuated thereby, comprises a passage for venting of the system, which communicates with the system at the topmost point of the latter, and a control member for opening and closing said passage ; the control member is a separate member from the primary piston and is moved to its closing position before the primary piston commences to move on its transmitting stroke and is not moved to its opening position until after the primary piston has come to rest on completion of its return stroke. The transmitting piston c, Fig. 1, is reciprocated by cam a on shaft b, a crank pin n on the latter reciprocating through connecting rod k<3> the control member k; during inoperative periods, the member k opens the passage o to permit venting of the system, and also opens a passage r through which liquid is forced by pump p also operated from the cam shaft, so as to flush the system and replenish leakage losses, the excess liquid returning to the reservoir u by pipe s; a relief valve w is provided; when the system is for actuating the valves of an internal combustion or other piston engine, the flushing liquid may be supplied by the lubricating pump of said engine. In a four stroke engine the two systems for actuating the inlet and outlet valves have a common control member. In a further modification, Fig. 4, downward movement of the control member k has a suction effect on liquid in the reservoir e, and when the passages o<1>, o<2> are uncovered, make-up liquid passes by gravity into the two systems, the air rising as bubbles and being vented.

Title: Improvements in methods of fabricating compound construction elements
IPC: B29C65/00
Filed: 1963-06-14
Abstract: 1,009,767. Building panels. L. ELSNER. June 14, 1963, No. 23796/63. Heading E1B. [Also in Divisions B5 and B7] Lightweight plane or curved construction elements, e.g. for vehicles, boat hulls, prefabricated houses or furniture, consist of a hard foam plastics core covered on each side by a layer of synthetic resin reinforced with glass fibre netting or matting. As shown, the core is assembled from a number of parts by inserting ribbons 6 of resin-impregnated glass fibre netting or matting between profiled adjacent edge surfaces. Individual construction elements are joined by overlapping the outer layers and inserting a ribbon in, for example, the C- shape shown; alternatively a spliced joint, as at 8, may be used. The reinforced joints are preferably located at points of high stress. When used as e.g. walls, the ribbons may be dovetail shaped to serve as a means of attaching the wall to the base plate (Fig. 5). Grooves or channels may be pressed in the elements to accommodate pipes or cables. The elements may be produced in moulds by applying to each surface of the mould a parting layer of wax and a gel coat of resin, and then applying successive layers of glass fibre netting or matting and polyester or epoxy resin. The pressing process may be achieved by means of an inflatable pressure pad interposed between the layers. After hardening, the pressure pad is replaced by the foam core, the surfaces of which have been coated with resin, the ribbons are then inserted and pressure is applied.

Title: Operating device for push button-dialled telephone
IPC: H04M1/276
Filed: 1971-04-19
Abstract: 1308402 Keyboards MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 April 1971 [11 March 1970 4 April 1970 20 April 1970] 23824/71 Heading G4H [Also in Divisions H1 and H4] The pushbuttons on a telephone can be operated electromagnetically by means of an overlaid unit 6 which contains electromagnets whose armatures operate the pushbuttons. The overlaid unit acts as a stand for the telephone set and is provided with buttons 12 so that a manual dialling facility is retained. The overlaid unit may be connected with an external control device provided with function buttons which cause a plurality of pushbuttons to be operated as well as digit buttons. An automatic dialling unit 201 which includes a magnetic tape, can alternatively be connected to the overlaid, unit. The overlaid unit may use an arrangement of selector rods moved by a first electromagnet and operating bars moved by a second electromagnet to move a hammer which operates the pushbutton. The particular button is selected by energizing the first and second electromagnets whose rods and bars intersect at the particular button location. Figs. 24 and 29, (not shown). In the external control device 8 the function pushbuttons release a motor driven rotary member which carries a magnet past a plurality of reed switches which cause the respective electromagnets in the overlaid unit to be energized or, alternatively, the first and second electromagnets to be energized thus operating a plurality of pushbuttons on the telephone set. The circuits used in the control device for energizing the pairs of electromagnets are described, Figs. 28, 35 (not shown). A further arrangement using cascaded bi-stable circuits to provide the energization for the overlaid unit electromagnets is also described, Figs. 36, 37 (not shown). In the automatic dialler attachment the numbers are recorded as pulses on a wide magnetic tape using a 4-track recording/replaying head. Each pushbutton in the overlaid number is provided with a reed switch whose contacts close when the button is pressed. This signal together with a timing signal are passed to AND gates which operate to provide on the four tracks of the tape a binary code marking of that digit, Figs. 43, 44 (not shown). When the tape is replayed the signals energize the electromagnets in the overlaid member to "dial" the number. In modifications and by the use of storage registers the recorder may have a single or double track head.
