Title: Improvements in or relating to measuring instruments
IPC: G01F1/50
Filed: 1936-02-24
Abstract: 471,115. Pressure gauges. FOXBORO CO. Feb. 24, 1936, No. 5505. Convention date, Aug. 20, 1935. [Class 106 (ii)] A differential pressure gauge of the manometer type is provided with a lever mechanism transmission which is compensated for pressure or temperature (e.g. by means of a Bourdon tube). The invention is shown applied to compensate a manometer of the mercury U- tube type for measuring the flow of fluid. One of the limbs of the manometer has a float which turns a shaft 11 in proportion to the differential pressure. Shaft 11 transmits its movements to a link 15 turning the pen 5, through linkwork the action of which is modified by a Bourdon tube 17 responsive to one of the two pressures involved. A pin 19 on shaft 11 engages a slotted plate 21 rigid with a frame which consists of two arms 23 spaced by pillars 25, 27. This frame 23 is pivoted coaxially with shaft 11, one pivot being marked 31. At the end 35 of one arm 23 is pivoted an L-shaped lever 33 which is mounted on a yoke 29 and is cranked, Fig. 3, towards the point 39 where it is pivoted to a link 37 ; the latter being pivoted at 47 to the driving crank 45 of the Bourdon tube 17. Point 39 is located, in all its positions, close to the axis of shaft 11 and arms 23. The link 15 is pivoted at 42 to a link 41, itself pivoted at 43 to the lever 33. The position of point 43 and length of link 41 are such that with frame 23 in zero position (full lines, Fig. 2) i.e. there is no flow, the point of connection 42 between parts 41 and 15 lies in the plane containing the point 43 and the axial line of connection 35 between parts 33 and 23. In Fig. 2 this connection 42 coincides with axis 35. If a differential pressure moves shaft 11 and frame 23, the parts take a position such as shown dotted, shortening or lengthening the distance from the axis of shaft 11 and frame 23 to the point 43, which distance constitutes the virtual crank acting upon link 15 through rod 41. Pivot screw 47 may be removed from crank 45 and placed in a fixed hole 49, in which case the compensation does not take place and the pen records differential pressure only. Tube 17 may compensate for the absolute pressure or absolute temperature of the fluid under test.

Abstract: 954,411. Field circuit control for generators starting prime-movers; alternators. SUNSTRAND INTERNATIONAL CORPORATION S.A. Feb. 14, 1962 [Feb. 14, 1961], No. 5625/62. Headings H2A and H2H. The rotors 13, 15 of an A.C. generator 11 and its exciter 12 are driven at constant speed by a shaft 10, and the field -winding on rotor 13 is connected to the output of rotor 15 through a control circuit 18, mounted for rotation with shaft 10 and arranged to disconnect the field winding when the generator 11 is used as an induction motor to run the driving system up to synchronous speed. Subsequently the generator 11 may run as a synchronous motor for a desired period depending on its application, e.g. in starting an aircraft engine. The generator field winding 22 is supplied from the exciter rotor windings 21a, 21b, 21c through a threephase rectifier 25 and a rectifier 26 whose control electrode 26a is connected through a Zener diode 30 to the secondary winding 28a of a transformer 28, the primary winding 28b of which is supplied from one phase of the exciter winding 21. During operation of machine 11 as a generator the exciter field 20 is energized and the voltage applied to electrode 26a renders the rectifier 26 conductive to energize the field winding 22. During induction motor operation of machine 11 the field 20 is not energized and the diode 30 prevents the low voltage which might be generated in the winding 21 by the residual magnetism of the field 20 from being applied to electrode 26a, so that rectifier 26 disconnects the winding 22 and the high voltages induced therein. Those voltages may be limited by a resistor 32 of value about ten times the resistance of winding 22. Members 25, 26, 28, 30 comprise the control circuit 18 of Fig. 1.

Abstract: 1,092,306. Catch fastenings. EVERED & CO. Ltd. Jan. 13, 1966 [Feb. 10, 1965], No. 5680/65. Heading E2A. A fastening device for holding a door or other hinged panel in a closed position with respect to a surrounding structure comprises a body 10 which in use is secured to one of the panel and the surrounding structure, a spring 23 loading a bolt 14 so as to cause a nose thereof to protrude from the body to a limited extent and a catch plate which in use is secured to the other of the panel and the surrounding structure and which is shaped to receive the nose of the bolt when the panel is in its closed position with respect to the surrounding structure, the nose of the bolt being connected by a connector 18 to a stop member 26 which is mounted on the body to slide thereon but which is prevented from rotating relative thereto, the connector being formed in one piece with the nose or the stop member and screw threadedly engaged with the stop member on the nose respectively, stop means 11 formed in one piece with the body being interposed between the nose and the stop member and being apertured to give passage to the connector, the bolt being urged in the direction of increasing protrusion of the nose to an extent limited by engagement of the stop member with the stop means by said spring which is interposed between and engages the nose and the stop means, the arrangement being such that the bolt is rotatable within and relative to the body to vary the effective length of the connector between the nose of the bolt and the stop member and thus to vary the extent of protrusion of said nose from the body. In the construction shown the stop means 11 is a wall of the body and the connector 18 is a shank which extends from the nose 15 of the bolt and the free end portion of which is screw threaded to receive the stop member 26 which, as shown, is a nut. The stop member 26 is contained in a cavity 21 the shape of which prevents rotation of the stop member. In the construction shown the forward end portion of the bolt 15 is hemispherical to form the nose and this is followed by a cylindrical portion, the cylindrical portion being received in a cylindricale bore in the body so that the bolt is rotatable relative to the body to vary the extent of its protrusion. When the connector is integral with the stop member the connector and stop member are in the form of a threaded bolt the head constituting the stop member and the shank of the bolt engaging a screw thread in the portion 15 of the bolt.

Title: Improvements in or relating to method of picking or dressing poultry
IPC: A22C21/02
Filed: 1945-03-07
Abstract: 603,639. Plucking poultry. INDUSTRIAL PATENTS CORPORATION. March 7. 1945, No. 5685. Convention date, Sept. 8. 1944. [Class 28(ii)] Poultry are plucked by mechanically suspending them with their axes vertical and subjecting each carcase during suspension to a substantially tangential beating substantially along the carcase and then performing a second similar beating in the reverse longitudinal direction of the carcase. The first beating is done against the lay of the feathers and the second beating is done with the lay of the feathers. A suitable automatic machine is described in U.S.A. Specification 2.328,770. Each fowl after scalding to open the pores and loosen the feathers is suspended first by its feet on detachable shackles 10 (e.g. as described in U.S.A. Specification 2,035,948). The shackles are hooked on a conveyer chain 8 and passed through a plucking machine 15-26. On emerging an operator reverses the fowl so that it is suspended by the head after which it passes through the other machine 15-26. Instead of having two machines, fowls may be suspended first on alternate shackles and after passing through one machine the operator may transfer a fowl to a vacant shackle on the inlet side and suspend it head up so that it passes through the machine a second time. This double treatment eliminates the need for removing unplucked feathers by waxing and removing the remaining feathers with the wax. One form of plucking machine, Fig. 2, comprises rubber fingers 21 on a pair of rotors 20 geared together and driven by a motor 22. The machine is provided with a housing 26 to catch the feathers. When a shackle 10 of the travelling conveyer actuates a switch 17, each rotor 20 with its plucking fingers 21 and the feather catching box 26 moves up over the fowl in plucking position for a predetermined interval of time and then recedes down out of plucking position, thus striking at the feathers in both directions. In an alternative machine the fowls might be lowered and then raised through stationary pluckers.

Abstract: 1345105 Fairleads H PASSING 9 Feb 1972 [20 Feb 1971] 6016/72 Heading B8B [Also in Division B7] A guide device for the traction cable of a conveying installation comprises two flanged rollers 1, 2 forming a closed roller aperture F therebetween, the rollers being arranged to open the aperture against a restraining spring 6, only when a substantially equal opening force is applied to each roller, whereby the rollers are opened by the engaging means of a conveyer vehicle attached to the cable, but not by the cable forces. In the embodiment of Fig. 1, each roller 1, 2 is mounted on an arm 3, 4, pivoted on a common pin 5, abutments 7 and 8 normally engaging blocking slides 9 and 10 to prevent any substantial opening of the rollers. Levers 11 and 12 extending from the arms 3 and 4 are engageable with the remote ends of the blocking slides to displace the slides against a restoring spring 13, out of alignment with the abutments 7 and 8, the lever 11 on the arm 3 displacing the blocking slide 10 which normally blocks the arm 4, whereby both rollers 1 and 2 must be simultaneously stressed in the opening direction to provide an opening action. In the embodiment of Fig. 2, the opening rollers 21, 22 of a four roller guide, are mounted on spring biased pivoted supports 23, 24 pivoted movement of the supports normally being prevented after a small movement, by blocking slides 29, 30 whose blocking positions are controlled by solenoids 35, 36. The latter are withdrawn to permit opening of the rollers, when the solenoids are energized through a switch 38 controlled by a coil 37, the latter normally being energized to hold the switch 38 open to deenergize the solenoids 35, 36. The actuation coil 37 is in a supply circuit with two contacts 33, 34 in parallel, the coil being de-energized only when both contacts are open. The contacts 33, 34 are each associated with one ov the roller supports 23, 24 and are each opened as that support is initially displaced towards opening. In another embodiment, Fig. 3 (not shown) two roller supporting arms are pivoted on a common pin and a lever pivoted to each support arm is pivoted at its other end to a common slider which is movable along a shaft against a compression spring force. The slide arm only moves along the shaft when both support arm levers apply substantially equal transverse opposing forces to the shaft to reduce sliding friction, and therefore the rollers can only open when both are substantially equally stressed. In the embodiments of Figs. 5 and 6 (not shown) the flanges of opposing rollers are shaped to ensure that the traction cable cannot apply an equal force to both rollers in their flange contact area.

[Class 39 (i)] A charge storage electrode for use in television apparatus, which is adapted to be charged by a composite beam of electrons so as to produce thereon an electric image corresponding to a picture, comprises a metallic electrode coated with a layer of aluminium oxide. The oxide is adapted to emit secondary electrons by which the charging, or in some cases the discharging by a scanning beam of electrons, is effected. The electrode may be a plate or grid of aluminium oxidized superficially by heating in air or oxygen or by anodic oxidation in an electrolyte of chromic acid. In one form of apparatus the image to be transmitted is thrown on a photoelectric gauze to produce a composite beam of photoelectrons which is focused onto the aluminium oxide surface and charges it negatively, or positively if secondary emission is predominant. A scanning beam then either produces secondary electrons in numbers corresponding to the negative charge, or neutralizes the positive charge, respectively. In another form, a grid-like storage electrode charged by a modulated scanning beam, controls a flooding electron beam. Specification 461,197 is referred to. According to the Provisional Specification any insulating metallic oxide may be substituted for the aluminium oxide.
