Title: Parenteral solution equipment and method of making
IPC: A61M5/14
Filed: 1959-02-13
Abstract: 907,017. Parenteral fluid containers. BAXTER LABORATORIES Inc. Feb. 13, 1959 [March 14, 1958], No. 5003/59. Class 81 (2). [Also in Group XVII] A collapsible, flexible translucent parenteral fluid container assumes the shape of a cube when filled with the parenteral fluid and has fluid outlet and inlet parts. A cubical envelope 13 is made from a rectangular sheet of thermoplastic translucent material by folding the sheet in two and heat-sealing the edges to form a flat envelope, adjacent heat-sealed edges 35, 36 at each corner then being superimposed and the sides of the envelope being folded along end portions of each diagonal 50 to form a triangular tab 42 at each corner. The rectangular sheet is creased or scored before folding to facilitate the formation of the tabs and so that the remainder of the envelope naturally takes a cubical shape and when completed will fold flat on its base for storage. The faces of each tab are sealed together along lines 43 where they adjoin the cubical part, the tabs 42 then being cut off. Outlet or inlet fittings 14, 14a comprise flanged tubes heat-sealed to the top wall of the envelope, the top wall portions within the tubes forming puncturable fluid barriers. The envelope 13 is stored in a rigid container 11 of corrugated cellulosic material, e.g. paper. Pilot tubes 19 are stored in compartments in the rigid container which has a synthetic plastic window 24 and a cover 12 with a slot 18. For storage, the slot is located against a side wall of the container and the closed container is wrapped in metal foil or coated with polystyrene, the edges being sealed. In use, the cover 12 is placed on the container so that flanges 18a of the fittings 14, 14a are supported by the edges of the slot and the envelope may be inverted and supported by a strap 29 which is affixed to its base and passes through a slot in the cover or by a tab 27 on the base of the cover 12. The envelope is filled through one fitting which is then closed by a plug or cap. In an alternative construction the base portion of the cubical envelope forms a chamber for anticoagulant, the top portion only of the envelope folding flat for storage. The envelope is housed in an open-ended box on the top of which pilot tubes are fixed, the box being placed in a rigid container with a top flap closure.

Title: Apparatus for producing leno fabrics in particular for the production of chenille cloth
IPC: D03D39/00
Filed: 1930-02-15
Abstract: 348,220. Weaving 1eno fabrics for chenille. GROSSENHAINER WEBSTUHL-UND MASCHINEN - FABRIK AKT.-GES., Grossenhain, Saxony, Germany. Feb. 15, 1930, No. 5171. Convention date, Dec. 31, 1929. [Classes 142 (i), 142 (iii), and 142 (iv).] In apparatus for weaving leno fabrics, such as that shown in Fig. 1 which is cut up to form chenille yarn as shown in Fig. 2, wherein leno warps c tie in the wefts in pairs, as shown, or singly or otherwise, the straight warps a either singly or in groups are passed through bail separators 45 arranged on the reed in front of spaces therein, the warps a then passing through needles 4 on a rail 6, thence over a guide roller 5 to the heald frame 3 which is moved up and down by chains and wires from a lever controlled by a grooved cam. The leno warps c are passed through holes in rails 1, 2 which are supported by but are movable longitudinally in the heald frame. The rails engage in the vertical slots of slides 38, 38, shown in plan view in Fig. 7, which are moved horizontally in a fixed U-shaped bail or guide by rods 35, 36 and levers on a shaft 33 rocked by lever mechanism controlled by a grooved cam. The rails are thus moved in opposite directions to cause the warps c to cross one another in pairs between each pick or pair of picks. The heald 3 is first raised, whereupon the warps c are caused to cross one another over the warps a. The heald 3 is then lowered whereupon the warps a are guided accurately by the parts 45, 4 into the spaces between the crossed warps c, the free ends of the bails 45 passing between the warps c before these engage between the guiding needles 4.

Title: Improvements in or relating to devices for indicating the petrol consumption of an internal combustion engine
IPC: G01F9/00
Filed: 1946-02-19
Abstract: 608,305. Measuring fuel comsumption. JEFFREYS, C. H., and JEFFREYS & EDMUNDS, Ltd. Feb. 19, 1946, No. 5183. [Class 106 (iii)] In a device for indicating the petrol consumption of an internalcombustion engine, a linkage is provided between the spring-actuated diaphragm of a petrol pump and a second diaphragm mounted in a chamber, movement of the second diaphragm against the action of an associated spring resulting in the movement of an indicating medium relatively to a graduated scale. A known type of diaphragm pump 2, Fig. 1, is actuated by a cam 8 driven by the engine, the cam rocking a lever 10 and, through the medium of a plunger 12, compressing the diaphragm spring 3 and drawing fuel through an inlet 2<1>. When the plunger 12 is released for upward movement, the diaphragm is moved upwards by its spring 3 an amount depending on the amount of fuel required at the carburetter 1, the flow to which is governed by a valve 5. Thus the upward movement of the diaphragm 4 is proportional to the fuel consumption and this movement is transmitted through levers 13, 16 to give proportional movement to a diaphragm 20 in a chamber 19. The space above this diaphragm communicates, by means of a pipe 22, with a gauge glass 23 and is filled with a fluid such as alcohol. A semi-non- return valve 24<1> allows slight leakage from the gauge glass to the diaphragm chamber, but permits full flow in the other direction, so that the level of liquid in the gauge glass 23 corresponds with the limit of upward movement of the diaphragm 4 at any particular time. A scale 24, Fig. 2, is provided adjacent the gauge glass 23 to indicate the rate of consumption, e.g. in miles per gallon. On the opposite side a scale 25 indicates the car speeds at which the various consumption rates should apply. In a modification, Fig. 4, the movements of the second diaphragm 20 are converted by gears 30, 31 to rotary motion which is transmitted to a rotary indicator 35. In another embodiment, a simpler form of linkage is used between the diaphragms 4 and 20 and a set-screw cooperating with a flexible pipe in the conduit to the gauge glass serves as a means for adjusting the level of fluid in the latter.

Title: Improvements in steering mechanism
Inventor: STABLE CHARLES EMERY FLEMING
IPC: B62D5/087
Filed: 1955-02-21
Abstract: 817,830. Vehicle power steering. KENT Ltd., G. Feb. 21, 1956 [Feb. 21, 1955], No. 5185/55. Class 79(5) A power assisted steering mechanism comprises a piston and cylinder unit C, Figs. 4 to 6, a control valve, a tube 5 connected to the valve spool 16 and to the manually operable part of the steering mechanism, and another tube 9 connected to the other part of the valve, to the piston 17 and to the transmission of the steering mechanism, the tubes 5, 9 being movable relative to the cylinder 18, connected together by a lost-motion device, and constituting supply and exhaust conduits to and from the unit. As further shown in Figs. 4 to 6 the invention is applied to a rack and pinion steering gear, the steering shaft 47 being connected by gearing 45, 46 to a pinion 25 engaging a rack 24. The rack 24 is connected by the tube 5 to the valve spool 16 and the tube 9 surrounding the tube 5 is connected to a block 26 connected by track rods 27 to the steerable wheels (not shown). The cylinder 18 is secured to a tube 29 in which the block 26 is slidable. The block 26 is provided with supply and exhaust connections 20, 22 leading to a hydraulic pump (not shown), the connection 20 leading to the bore 21 in the tube 5 and the connection 22 to the annular space 23 between the tubes 5, 9. The spool 16 has lands 31, 32, 33, 34, the bore 21 leading to a duct 30 between the lands 32, 33. The piston 17 has lands 35, 36, 37, 38, 39, the space 23 being connected by a bore 41 to ducts between the lands 35, 38 and 37, 39. The piston 17 also has bores 40 each leading to opposite faces of the piston, the bores 40 being connected to ducts between the lands 35, 36 and 36, 37, whereby manual rotation of the shaft 47 causes movement between the spool 16 and piston 17 to cause one end of the cylinder to be connected to exhaust and the other end to exhaust to cause power assisted movement of the block 26. Relative movement between the spool 16 and piston 17 is resisted by a ball 43 in a bore 42 engaging a groove 44 in the bobbin 16, the ball being urged into engagement with the groove by a spring and by hydraulic pressure, the bore 42 being connected by a passage 45 to the duct 30. In a modification Fig. 1, the cylinder 18 is secured at 19 to a fixed part of the vehicle, the tube 9 is connected by a block 8 to a drag link (not shown), and the tube 5 is connected by a block 4 to the drop arm of a cam and follower steering gear (not shown), the tube 5 carrying within the block 8 a flange abutted by two springs in turn abutting the block 8 whereby relative movement in the valve on manual actuation of the gear is resisted.

Title: Improvements in cloth guiding and stretching device
IPC: D06C3/00
Filed: 1930-02-17
Abstract: 344,191. Guiding and stretching webs. TEXTILE - FINISHING MACHINERY CO., 83, Exchange Place, Providence, Rhode Island, U.S.A. Feb. 17, 1930, No. 5227. Convention date, May 6, 1929. (Class 100 (i).] In a cloth-guiding and stretching device, of the type employing pairs of guiding-rollers 20, 24, Fig. 2, one of which is rotatably mounted and controlled electromagnetically by a web-feeler, so that excessive movement of the edge of the web causes the movable roller to be moved out of operative engagement with the web, only one circuit, which is of low voltage, is employed, the control switch of which is carried by the feeler. The movable roller 24 is mounted on an arm 27 pivoted at 25 and having at its other end an armature 29 and counterpoise 30, which is not quite sufficient to balance the weight of the roller 24. The small additional force required to bring the latter into operative contact with the fixed roller 20 is supplied by means of a solenoid 34, which attracts the armature 29, the current being obtained from the commercial alternating current supply by means of a converter and step-down transformer. The solenoidal circuit includes a switch, comprising a fixed contact 39, Fig. 7, and a movable contact 40, carried by a resilient strip 45 attached at its free end 47 to the feeler member 48, so that in the normal position the members 39, 40 are held in contact. The feeler 48 engages the edge of the web, and if the latter moves laterally an excessive distance, the contact is broken, the solenoid deenergized, and the roller 24, being no longer counterbalanced, falls into its inoperative position, until the opposite guiding unit brings back the web into its line of feed, when contact is again made. The movement of the arm 27 is limited by a finger 31, engaging an adjustable abutment 33. In modifications, a spring or other control may be used instead of gravity, or the electromagnetic action may cause the rollers to separate, while their contact is caused by some opposite force.

Abstract: 360,305. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Roberts, W. van B. ; 155, Hodge Road, Princeton, New Jersey, U.S.A.) Feb. 19, 1931, No. 5297. Convention date, Feb. 19, 1930. [Class 40 (v).] A superheterodyne receiver comprises a pair of valves 7, 8, in push-pull, a signal receiving circuit 9 and a local oscillation circuit 3, one of said circuits being symmetrically coupled with the input circuits of the valves, and the other coupled to the input of one valve only, while the intermediate frequency amplifier is differentially associated with the output inductance L1. When the oscillator 3 is inoperative no signal is passed to the intermediate frequency amplifier owing to the in-phase input and differential output; interference from undesired signals is thus eliminated. A band pass filter may be used between the aerial and circuit 9, which may be untuned.
