Title: Cow Stall
IPC: A01K1/12
Filed: 1967-06-06
Abstract: 1,160,326. Cow stall. HOLM TRACTOR & EQUIPMENT CO. 6 June, 1967 [6 June, 1966], No. 26164/67. Heading A1M. A cow stall for use in milking comprises two side walls 12 and 18, a rear wall 14 and a front wall 16, an entrance gate 19 for admitting cows to the elongated space enclosed by the walls and stall adjusting means for moving the front wall with respect to the rear wall to adjust the length of the space for each cow. The length of the stall is shortened by the plunger 60 being pushed outward from the piston 58 causing the link 62 to pivot clockwise so that the link 68 pulls on the three leg member 44 which, as it is connected to the front wall 16 by the pin 50, pulls the front wall inwardly. Movement of the front wall pulls the link 76 downwards and causes the centre post 80 to rotate inwardly so narrowing the stall. The front wall 16 and the exit gate 21 are opened by the plunger 42 being withdrawn into the piston 40 so pulling the leg 48, and hence the front wall, in a counter-clockwise direction. This movement causes the leg 52 to push on the link 54 and hence open the gate 21. The entrance gate 19 is opened by the plunger 90 being withdrawn into the piston 88 so that the leg 92 rotates clockwise and hence the leg 98 forces the link 100 against the gate causing it to open. The food pail 20 can be retracted when the front wall and the exit gate are opened. The piston and linkage arrangements are mounted on the cross-members 24 and 34 on top of the walls of the stall.

Filed: 1974-06-13
Abstract: 1459465 Active filters; adaptive equalizers INTERNATIONAL BUSINESS MACHINES CORP 13 June 1974 [12 July 1973 (2)] 26231/74 Headings H3U and H4R An equalizer for equalizing an input signal r(t) comprises two filters having impulse responses h 1 (t), h 2 (t), a Hilbert transformer having an impulse response g(t) and a summing circuit arranged to give two quadrature outputs y(t) and y(t) where In a first embodiment, Fig. 4, the input signal is fed to a first delay 10 and via a Hilbert transformer 9 to a second delay 13, the inputs to the delays being sampled at a rate 1/T. The outputs from tappings along the delays are weighted by four sets of weighting coefficients M<SP>1</SP> 0  ... M<SP>1</SP> 2N , M<SP>2</SP> 0 ...M<SP>2</SP> 2N , M<SP>3</SP> 0  ... M<SP>3</SP> 2N , M<SP>4</SP> 0  ... M<SP>4</SP> 2N  the outputs from which are summed in four adders 11, 12, 14, 15. The outputs from 11, 14 are then differenced to provide the output y(t) and the outputs from 12, 15 are summed to provide the output #y(t). In a second embodiment, Fig. 5 (not shown) the number of multipliers is reduced but the number of delay tappings and the sampling rate is increased. Only one set of outputs is taken from each delay, and the #y(t) output is derived from the y(t) output by means of a second Hilbert transformer (24). In a third embodiment, Fig. 8, the input is fed in parallel to the two filters (which may share a common delay) and their outputs are applied to respective Hilbert transformers 42, 43. The y(t) output is then formed by differencing the output from one filter with the Hilbert transformed output from the other in circuit 44, and the #y(t) output is formed by adding the other output to the transformed output from the first in circuit 45. The filters may be made adaptive by feeding the y(t) and #y(t) signals to error detecting circuits which produce control signals for adjusting the multiplication coefficients of the filters, Figs. 6, 9 (not shown).

Abstract: 1437923 Fuelling reactors WESTING- HOUSE ELECTRIC CORP 17 June 1974 [25 June 1973] 26655/74 Heading G6C An arrangement for transferring fuel assemblies between a fuel handling building 14 and a reactor containment 10, the former including both new and spent fuel pits and an operating deck 74 on the top surface of walls forming the pits, includes a canal 32 adapted to be filled with water and housing a fuel transfer conduit 68. The canal 32 extends through the walls 12, 38 of both the reactor containment 10 and the fuel handling building 14, and includes a rail track 48 on which a car 42 having a frame 44 supported on wheels 46 may move. The car is driven by a motor and linkage (Fig. 2C, not shown) extending from the operating deck 74 to a chain belt drive connected to a long pusher arm 80 extending from the car. A container 52 pivotally mounted at its centre of gravity on the car 42 is actuated by means of an hydraulic cylinder 58 containing a piston connected through linkages 64, 66 to the container 52. When in the vertical position shown in solid outline in Fig. 2A, the container 52 receives a fuel element 15 and is then rotated to the horizontal position shown in broken outline to permit movement of the car 42 through the fuel transfer conduit 68 to the fuel handling building 14. Return to the vertical position provides for fuel element removal and the reverse process is applied when transferring a fuel element in the opposite direction. When a fuel element replacement operation is to take place, the reactor containment 10 is flooded to the level 40 by removing a blank flange 71 from one end of the fuel transfer conduit 68 and opening a valve 70 at the other end by means of a hand wheel 72 (or motor) mounted on operating deck 74 and connected to the valve by a wall-mounted valve stem 76. Water then flows from the fuel handling building 14 through the conduit 68 and into the reactor containment 10, which containment is dry during reactor operation. Stop means (not shown) are provided at each end of the track 48 and are engageable by the pusher arm 80 extending longitudinally from the car 42 whereupon an overload torque limiter deenergizes the drive motor. To detect whether the container 52 is vertically or horizontally oriented and to determine the end position at which the car 42 is stopped, proximity switches (not shown) are provided which close circuits to appropriate signal lights on panel boards 114, 116 mounted on the operating deck 74.

A rocket projectile provided with fins 11, which are deployed after the projectile leaves the launching tube 2, comprises a combustion chamber 1 containing a solid propellant 3 and closed at the rear by a member 4. Within the member 4 are four passages 5a shaped to form the upstream part of jet nozzles 5, which surround a cylindrical inwardly directed boss 6 housing a spring- loaded plunger 13. A carrier 7, held in abutment with the member 4 by a sleeve 8, supports the divergent ends of the nozzles 5 and has a bore 9 coaxial with the bore of cylinder 6. The fins 11, Fig. 3, are pivoted on pins 10 fixed in the carrier and abut arms 16 carried by the plunger 13, guide discs 17 for the fins being mounted on the arms 16. Spring 14 tends to drive the plunger 13 rearward to deploy the fins, but before firing a dished plate 18 holds the fins retracted. On ignition of the propellant, the gases produced dislodge the plate 18 and the fins 11 then bear against the wall of the tube 2 due to the thrust of spring 14, but while in the tube the plunger covers at least partially a duct 15 communicating with the combustion chamber. When the rocket leaves the tube 2, the fins are no longer positively held and the plunger moves so that the duct 15 is cleared. The propellent gases then enter cylinder 6 and reinforce the thrust of the spring 14 to deploy the fins 11. A second duct of smaller diameter may provide permanent communication with the combustion chamber or a groove for the same purpose may lead from the duct 15 either along the inner wall of the cylinder 6 or the outer wall of the plunger.
