Abstract: 549,761. Carburetters ; extra air valves. CALIFORNIA MACHINERY & SUPPLY CO., Ltd. Dec. 31, 1941, No. 16849. Convention date, Nov. 19, 1940. [Classes 7 (ii) and 7 (iii)] In a device for cutting off the supply of mixture to the engine when the throttle 10 is moved to idling position and the engine is turning over at a speed, or the depression in the manifold becomes, greater than that for normal idling, by means of a cut-off valve 21 closed by the action of the depression on a piston 26 as admitted thereto by a pilot valve 51, valvular means are provided, such as ports 75, 76, which come into operation to give the depression direct access to the piston 26 when this has moved to the right in Fig. 1 to close the valve 21. By this means the valve 21 is held closed independently of the position of the pilot valve 51, and will not be opened again<SP>1</SP>until the depression reaches a point below that for which the pilot-valve spring 57 is set, and fluttering of the valve 21 is avoided The piston 26 is also connected to an extra-air piston valve 30 which is also moved to the right to uncover ports 34 to admit air from an inlet pipe 35 to a passage 36 adjustable at 38 and. opening at 37 on the engine side of the cut-off valve 21. The manifold depression is communicated to the pilot valve and to the port 76 by a passage 60, 61, also opening on the engine side of the valve 21. A check valve 62 prevents injury from backfires. An air-bleed port (not shown) leading to the right-hand side of piston 26 is closed by this piston at the end of its movement to the right. The ports 75, 76 begin to register before the air ports 34 are opened. A further passage (not shown) admitting air to the right-hand side of the piston 26 is closed by a valve which is opened by the throttle 10 then this is moved from the idling position, the piston 26 being thereby returned to the left so as to open the valve 21. In a modification the piston 26 is of differential form.

Title: Needle punch machine and method
IPC: D04H1/46
Filed: 1961-05-10
Abstract: 923,762. Needling fibrous batts. CHATHAM MANUFACTURING CO. May 10, 1961 [May 26, 1960], No. 16958/61. Class 42 (2). A non-woven fabric is produced from a web 10 of loosely matted fibres by advancing the web intermittently between opposed sets 22, 24 of needles and causing the sets of needles to penetrate opposed surfaces of the web when it is stationary. The web 10 which may be formed from at least two layers 16, 18, Fig. 6, separated by a loosely woven fabric 20 is fed intermittently by a conveyer 66 to the needle sets 22, 24 which sets alternately penetrate the web 10 at an actute angle to the direction of movement thereof. The needles 30, 32 having barbs 48 are mounted on boards 26, 28 and are adapted to pass through apertures (not shown) in guide plates 36, 38 curved as shown. The plates 36, 38 are carried between plates 56 having slots 58, 60 therein to carry shafts 62, 70 respectively. The shaft 70 carries an out-feed roller 72 with which a weighted roller 80 co-operates. When the shaft 70 is rotated in step-by-step increments by a one-way clutch and brake assembly (not shown) mounted thereon a pulley 64 on the shaft 62 is intermittently rotated through chain 76 entrained around sprockets 74, 78, 68 so that the conveyer 66 is moved intermittently. A link 88 pivotally connects a crank 86 to a disc 89 keyed to a shaft 90 rotated by a motor 98 so that the crank 86 is oscillated. The crank 86 is connected to the drive member of the one-way clutch so that clockwise movement thereof causes rotation of the shaft 70 and therefore of the roller 72 and also movement of the conveyer 66. During counterclockwise movement of the crank 86 the shaft 70 is stationary. The needle boards 26, 28 are mounted on arms 100, 108 pivoted at 102, 110 to vertical standards 104 and are connected together by rods 112 to move in the same direction simultaneously. Crank arms 120 coupled to cranks 122 carried on a shaft 124 are pivoted to the board 28. The shaft 124 is driven by the shaft 90 to cause continuous up and down movement of the boards 26, 28. The operation is timed so that the web is moved after one set of needles has left the web and before the penetration of the second set. The needled batt produced by this apparatus has rows extending lengthwise thereof. The fibres in the rows extend from one surface of the batt to the other and are entangled with fibres in the other surface and vice versa, and some of the fibres between the surfaces are interentangled, Fig. 14.

Abstract: 292,356. McKissick, W. H. June 25, 1927. Pulley-blocks. - The sheave, or sheaves, is enclosed by a housing comprising side members such as 10, 11, Fig. 1, guard-flanges such as 17 extending transversely across the ends of the housing and guards such as 18 overhanging the sheave between the guard flanges. As shown in Fig. 1, the members 10, 11 are mounted off centre on the axle 15, and the flanges 17 are contiguous. When the becket fastenings are removed, the member 10 may be turned through 180‹ so as to leave gaps between the flanges 17 at both sides of the block for removal of the rope. In modifications, the block is opened by turning one of the side housing members through 90‹, or by shifting it laterally. In another form, Fig. 4, the guard flanges 17<1> are removable, and are provided with lugs 19 which rest in notches of the housing members. In Fig. 6, housing members 23 with ends 24 forming guard flanges are hinged to one side plate 22 and fastened by bolts 30 to flanges on the opposite side plate 25. In a modification, the hinges are at the outer corners, as at A. In Fig. 9, a gap 38 for the rope is provided between guard-flanges 37 of fixed housing members 34. In a modification the gap are closed by removable plates. In a further modification, Fig. 12, the plates 34 are hinged along the upper edge at 42, and the guard flanges are near together when the block is closed. In Fig. 17, a partition plate 88 between two sheaves of the block carries oppositely-disposed tapering flanges 89, which cooperate with guard flanges 85 on the housing members, and the plate 88 may be turned on the axle 83 to open the block, the flanges 89 passing over the upper guards 87.

Title: Weighing device and method
IPC: G01G13/08
Filed: 1976-04-27
Abstract: During filling with products, the weight per pack must not fall below a minimum value. On the other hand, the minimum weight should be exceeded as little as possible, in order to avoid any losses. The weighing apparatus comprises a container (19), in which a product is weighed, a conveying means (20) in order to feed the product to the container (19), and a weighing meter (12) in order to determine the weight of the product in the container (19). The weighing meter (12) has a member (146) which is moved in relation to a trigger device and in proportion to the weight of the product in the container. The trigger device comprises means (102, 144, 147', 148') which generate a first signal. This signal ensures that the speed of the conveying means (20, 24) is progressively reduced when the weight of the product in the container (19) approaches the desired weight. A second signal stops the conveying means (20, 24) when the desired weight is reached. <IMAGE>

Title: Improvements in or relating to brush gear, especially for electric meters and the like
IPC: G01R11/30
Filed: 1926-07-07
Abstract: 255,070. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitdts Ges.). July 7, 1925, [Convention date]. Brush-holders.- Brush gear especially for electric meters &c. is arranged so that the commutator can be freed without complete removal of the brushes. The brushes are carried by a common holder which is arranged displaceably or rotatably with respect to the commutator and has an arm preventing the brushes from coming together when they are removed. In the construction shown in Fig. 2 the brushes 1 are carried by a brush-holder 3 which is arranged displaceably with respect to the support 4 and can be fixed in position by means of a screw 5. An arm 6 on the brushholder prevents the brushes from coming together when withdrawn from the commutator 2. The ends of the brushes are bent outwardly to facilitate replacement on the commutator. The brush-holder 3 may be arranged to swing instead of slide. In a modification, Fig. 4, pins 7 are fitted on the brushes, and are pushed aside by a guide 8 on the brush-holder support as the brushes are withdrawn from the commutator. The pins 7 also prevent the brushes from coming together when completely withdrawn. In a further modification, Fig. 5, guides 10 are firmly connected to the brushes and serve as a protection therefor. In shifting the brushes on to the commutator, the guides and brushes are pressed apart. The protection arrangements may be of bent wire or of sheet metal in the form of a fork.

Abstract: 1,064,887. Valves. INTERNATIONAL NICKEL CO. OF CANADA Ltd. April 22, 1965 [Apri 23, 1964], No. 17039/65. Heading F2V. [Also in Divisions F1 and F4] A plurality of compressed air-operated singlestroke piston and cylinder devices (23, 21), Fig. 1 (not shown), are actuated sequentially by associated three-land spool valves (2) each spool (12) being movable between rest and cocked positions within a body (3) having a main air inlet port (10), a port (9) connected to one end of its associated motor cylinder (21), or port (11) connected by a duct (34), Fig. 4 (not shown) to the main inlet port (10) of the next valve in the series and an exhaust port (8) the arrangement of ports and lands (13, 17, 18) being such that when the valve spool is in the next position it connects main inlet port (10) to port (11) and connects port (9) to exhaust port (8) whereas in the cocked position, Fig. 2 (not shown), inlet port (10) is connected to port (9) and ports (8, 11) are isolated and assuming all the valves to be cocked, compressed air when admitted to inlet (10) and port (9) of the first valve advances piston (23), and air in front thereof is forced through a cylinder end port (24) and a passage (20) to the end (4) of the valve body (3) to return the spool (12) to its rest position thus allowing compressed air to pass from ports (10, 11) through conduit (34) to the inlet port (10) of the next valve in the series which remains cocked until advance of the piston of its associated motor is completed. Air compressed by each piston (23) during advance serves to return the piston against substantially no load since the space behind it is connected to exhaust port (8) and the piston is held in retracted position by inlet air being bled through a passage 32 in load (18). Simultaneous cocking of the valves is effected by feeding compressed air from a leader (30) through ducts (36) leading to ports 19 in the ends 5 of the valve bodies. The advance stroke of the piston-rod (25) may scrape crust from a furnace tuyere or may operate a metal stamping tool.

Title: Improvements in or relating to electrical control circuits for electrostatic precipitators
Inventor: ROBINSON THOMAS PHILIP
IPC: B03C3/66
Filed: 1953-06-19
Abstract: 750,013. Automatic control systems for electrostatic precipitators. STANDARD TELEPHONES & CABLES, Ltd. June 11, 1954 [June 19, 1953], No. 17040/53. Drawings to Specification. Class 38 (4). In a control system for a precipitator as described in Specification 749,832, wherein simultaneous conditions of low electrode voltage and high discharge current-indicative of flash-over in the precipitator-cause operation of a relay which, by modifying the D.C. excitation applied to series and shunt reactors in the supply circuit for the E.H.T. transformer feeding the precipitator, effects a temporary voltage reduction to an arc extinction value for a period determined by a timing circuit associated with the relay, a further control is provided which is responsive to the flash-over rate and which effects permanent voltage reductions to limit this rate when it tends to exceed a given value, as may occur with progressive fouling of the precipitator. The further control may comprise a " make " contact on the temporary voltage reducing relay, over which contact a resistance-capacity integrating circuit is energized from a D.C. source, the voltage to which the condenser charges thus being dependent upon the flash-over rate. A valve-controlled relay, responsive to the condenser voltage, operates at a predetermined flash-over rate and reduces the voltage applied to the E.H.T. transformer by modifying the supply of D.C. to the control windings of the saturable reactors, this being effected by tap-changing on auxiliary transformers supplying rectifiers which feed the control windings. After a voltage reduction has been effected a further pair of integrating circuits and associated valve-controlled relays become operative, one circuit being energized in response to each flash-over and the other being continuously energized from a D.C. source. According as to which of the two valves conducts first, the system operates either to restore the E.H.T. to its original value or to effect a further voltage reduction therein. Specification 684,024, [Group XL (a)], also is referred to.
